Laparoscopic vs Open Stomach Surgery: What Do the Small Incisions Change for Recovery?

The pre-op appointment is almost over when the question finally comes out. The patient has read the consent form, nodded through the explanation of the pouch and the staple line, and then asks the thing that has been bothering her since the first consultation: “Will I have four little cuts or one big one, and does it really matter?”

It is a fair question, and a more precise one than it sounds. In the debate over laparoscopic vs open stomach surgery, the part that happens inside the abdomen, the reshaping of the stomach, is essentially the same. What changes is the route in. Whether a surgeon works through incisions the width of a fingertip or through a single cut down the upper belly shapes how the first breath after waking feels, how soon walking to the bathroom is realistic, and what the abdominal wall looks like years later.

This explainer follows that difference from the operating table to the six-week check, using what the mainstream evidence actually supports, and no more.

What does laparoscopic vs open stomach surgery actually mean?

Both terms describe how a surgeon reaches the stomach, not what is done to it. “Open” surgery means one incision long enough for the surgeon to see and handle the organs directly. In weight-loss operations that cut usually runs vertically down the upper abdomen, and it passes through skin, fat, the tough sheet of connective tissue called fascia, and the muscle beneath.

“Laparoscopic” surgery, often called keyhole surgery, replaces that single opening with several small ones. A laparoscope is a thin tube carrying a camera and a light; it sends a magnified picture to a screen. Long, narrow instruments pass through other small ports. For a gastric bypass, MedlinePlus describes four to six small cuts in the belly, each roughly the size of the incisions the NHS quotes for diagnostic laparoscopy, around 1 to 1.5 cm.

The surgeon inflates the abdomen with carbon dioxide gas to create working space, a bit like lifting the roof of a tent so you can move around inside it. That gas is the reason many people describe a strange shoulder or upper-back ache for a day or two afterward; it irritates the diaphragm, and the nerves there share pathways with the shoulder.

Inside the abdomen, the steps are the same whichever route is used. In a sleeve gastrectomy, a long tube of stomach is stapled and the rest removed. In a gastric bypass, a small pouch is created and joined to the small intestine. The staple lines, the new connections and the long-term physiology are identical.

So when patients compare laparoscopic vs open stomach surgery, they are really comparing two things: how much the abdominal wall is disturbed, and how well the surgeon can see and work. Everything in the recovery story flows from those two facts.

How does a laparoscopic stomach operation actually happen, step by step?

The day begins the same way for both approaches. General anesthesia means you are fully asleep and a breathing tube supports your lungs. Compression stockings or sleeves on the calves start working before the first incision, because immobility on an operating table is one of the moments when clots are most likely to form.

For a laparoscopic operation, the surgeon makes the first small cut, usually near the belly button, and introduces the gas. Once the abdomen is domed, the camera goes in and the team watches the screen rather than the patient’s belly. Further ports are placed under direct vision so instruments can approach the stomach from different angles.

The stomach is then freed from its attachments, a stapling device divides it, and, depending on the operation, a new connection to the intestine is made. Surgeons commonly test the staple line or joint with dye or air to look for leaks before finishing. The gas is released, the ports come out, and the small incisions are closed with dissolving stitches, glue or small strips.

Mayo Clinic notes that gastric bypass typically takes a few hours and is usually performed laparoscopically. Laparoscopy can take somewhat longer than open surgery for the same procedure because instruments are worked at arm’s length, though this varies with the team’s experience and the patient’s anatomy.

An open operation follows the same internal sequence. The differences are that the surgeon’s hands, not instruments, do much of the work, there is no gas, and closing takes longer because the fascia and muscle layers must be sutured back together securely enough to hold under the pressure of coughing and standing.

Either way, you wake in recovery with a nurse checking your breathing, pain level and wound dressings. The next few hours look surprisingly similar; the divergence begins when you first try to sit up.

On which side of the body is the stomach, and why does that affect the incision?

People often place the stomach lower and more central than it really is, somewhere around the belly button. In fact, Cleveland Clinic describes it as sitting in the upper left part of the abdomen, tucked under the lower ribs and just below the diaphragm, the dome of muscle that separates the chest from the belly. It is J-shaped: the wider upper portion lies to the left, and the narrower lower end curves toward the middle where it meets the small intestine.

That position matters for surgery in two ways. First, the stomach is high, close to the spleen, the liver and the diaphragm. An open incision has to be long enough, and placed high enough, to reach those upper corners, which is why it usually starts just below the breastbone. That is also a region where the abdominal wall moves with every breath, so a long wound there hurts most when you inhale deeply or cough.

Second, the stomach’s position under the rib cage is awkward for direct vision. A camera on a rod can slide up under the ribs and look at the top of the stomach from angles a surgeon’s eye through an open wound simply cannot achieve. Many surgeons feel this magnified, well-lit view is one of the practical advantages of laparoscopy for upper-abdominal work, not just a cosmetic one.

A thick apron of abdominal fat deepens the problem. In someone with a large body, the distance from skin to stomach through an open incision can be considerable, and the wound has to be held open with retractors for hours. Laparoscopic ports simply pass through that depth, and the instruments do the reaching. This is part of why keyhole techniques became standard in weight-loss surgery earlier than in some other fields.

Why does incision size change recovery? The mechanism, plainly

Think of the abdominal wall as a corset of muscle you use constantly without noticing: to sit up, to cough, to take a deep breath, to stand from a chair, to laugh. A long open incision cuts across that corset, and every one of those movements pulls on the healing edges. Pain after open surgery is not mainly from the stomach; it comes from the wall.

Pain then sets off a chain. When breathing deeply hurts, people take shallow breaths and avoid coughing. The lowest parts of the lungs do not fully inflate, mucus is not cleared, and the risk of chest infection and low oxygen rises. When getting out of bed hurts, people stay in bed, and blood pools in the calf veins, which is precisely how deep vein thrombosis, a clot in a deep leg vein, begins. Stronger painkillers help with the pain but bring their own drowsiness, nausea and constipation, which slow eating and walking further.

Small incisions interrupt that chain near its start. The NHS lists the practical advantages of laparoscopy as a shorter hospital stay, faster recovery, less pain and bleeding, and less scarring. None of these is magic; they follow from leaving most of the muscle and fascia intact.

There is a longer-term mechanism as well. Any incision through fascia is a weak point where bowel or fat can later push through, forming an incisional hernia. A long vertical incision creates a long weak line; a handful of small ports create small ones. MedlinePlus lists incisional hernia among the risks of gastric bypass, and surgeons broadly regard it as more common after open than laparoscopic operations.

What incision size does not change is what happens inside. A staple line heals at the same pace whether the skin above it has one scar or five.

Open vs laparoscopic gastric bypass and sleeve: a side-by-side comparison

The table below summarizes what the two approaches typically look like from the patient’s side. Ranges are typical, not promises, and your own team will give you figures for your situation.

Feature	Laparoscopic (keyhole)	Open
Incisions	Usually 4 to 6 small cuts (MedlinePlus), each roughly 1 to 1.5 cm (NHS)	One long incision in the upper abdomen
Surgeon’s view	Magnified camera image on a screen	Direct sight and touch
Typical hospital stay	Often 1 to 3 days after gastric bypass (MedlinePlus)	Usually longer; set by the team
Early pain	Generally less; gas-related shoulder ache is common	Generally more, worst with breathing and movement
Wound complications	Lower rates of infection and incisional hernia are widely reported	Higher rates, particularly hernia along the incision
Return to usual activity	Often 3 to 5 weeks after gastric bypass (MedlinePlus)	Often longer, especially for heavy lifting
Internal risks (leak, bleeding, clots)	Similar	Similar
When used	Standard approach for most weight-loss operations (Mayo Clinic)	Chosen for specific anatomy, prior surgery or safety during the operation

Two things stand out. First, the columns diverge on everything that involves the abdominal wall and converge on everything that involves the stomach itself. Second, the open column is not a “worse” operation; it is the same operation through a different door, chosen when that door is the safer one.

People searching for open vs laparoscopic gastric bypass results sometimes expect to find that one produces more weight loss. Long-term weight outcomes depend on the internal anatomy created and on eating and activity habits afterward, not on the route in. The comparison is about recovery and wound risk, and on those measures the small-incision approach has become the default for good reason.

Who usually gets keyhole surgery, who may need open, and who is asked to wait

For most people undergoing sleeve gastrectomy or gastric bypass, the laparoscopic route is the starting assumption. Mayo Clinic describes gastric bypass as usually performed laparoscopically, and the same is true of the sleeve. The question is less “do I qualify for keyhole?” and more “is there a reason keyhole is not right for me?”

Reasons a surgeon may plan an open operation, or warn that one is likely, include extensive previous abdominal surgery with dense scar tissue, called adhesions, that can bind organs together and make safe camera work difficult; very large hernias in the abdominal wall that need repair at the same time; unusual anatomy found on imaging; or a body shape in which the gas cannot create enough working space. Some heart or lung conditions make the pressure of the gas on the diaphragm harder to tolerate under anesthesia, and the anesthesia team weighs in on that.

Being asked to wait is different from being turned down. Weight-loss surgery programs commonly pause the timeline when blood sugar is poorly controlled, when smoking has not stopped (nicotine slows wound healing and raises the risk of leaks), when sleep apnea has not yet been assessed and treated, or when nutritional deficiencies need correcting first. The NHS describes weight-loss surgery as available to people who have tried other approaches and who commit to long-term follow-up, and most teams want to see that groundwork before booking a date.

The decision about approach is made by the operating surgeon, often with input from anesthesia and the wider team, and it is revisited right up to the operation. If you are told open surgery is planned, it is worth asking what specifically drives that choice; the answer is usually concrete and reassuring rather than vague.

When is open surgery needed part-way through? Understanding conversion

Consent forms for laparoscopic surgery almost always include a line about the possibility of converting to open surgery. It reads alarmingly, but conversion is a safety valve, not a failure.

Conversion means the surgeon begins with small incisions and then, during the operation, decides that a single larger incision is the safer way to finish. Common reasons include bleeding that is difficult to control through the ports, adhesions that hide the anatomy, an unexpectedly large liver blocking the view of the stomach, or equipment limitations. Surgeons describe the mindset simply: if they cannot see clearly, they change the view.

What this means for you is that you may wake with a wound you did not expect, and your recovery timeline shifts toward the open column of the table above. Your nurses and surgeon will explain what happened and why, and the internal operation is usually completed exactly as planned.

The likelihood of conversion is low in established weight-loss surgery programs, but it is higher when the risk factors listed in the previous section are present. This is why surgeons sometimes say, “I plan to do this laparoscopically, but I would put the chance of needing to open at higher than usual for you.” That sentence is a good sign; it means the team has thought about your specific anatomy.

If conversion happens, the practical differences are the ones already described: more attention to breathing exercises, more support to get moving, a longer stay in hospital and a longer wait before lifting. The risk of incisional hernia along the new wound is monitored at follow-up.

Patients often ask whether they can refuse conversion in advance. In practice, no responsible surgeon will agree to that, because it would mean promising to continue in a situation they have judged unsafe. The better conversation is about what would prompt it and how the team would manage recovery afterward.

Laparoscopic surgery recovery time: what the first 48 hours usually look like

Waking after a laparoscopic stomach operation, the first sensations are usually a dry throat from the breathing tube, tightness across the upper belly, and, for many people, an ache in one or both shoulders from the gas. Nurses monitor heart rate, temperature, oxygen level and pain, and will ask you to take deep breaths early and often.

The single most useful thing you can do in these hours is move. Most programs aim to have patients sitting on the edge of the bed within hours of surgery and walking short distances the same day or the next morning. Walking pushes blood through the calves, reinflates the lungs and wakes up the bowel. After laparoscopy this is uncomfortable but usually possible; after an open operation it is possible too, but needs more pain control and more help.

Fluids come first, in sips, once the team is satisfied there is no sign of a leak. Some units do a swallow X-ray; others rely on clinical observation. Nausea is common on the first day and is treated as it arises.

MedlinePlus gives a typical hospital stay of 1 to 3 days after gastric bypass, and NHS guidance for weight-loss surgery describes most people going home within a few days. Going home depends on drinking enough, walking safely, having pain controlled with tablets and having no warning signs, not on the calendar.

Before discharge you will typically be shown how to care for your small wounds, given a clot-prevention plan that may include injections for a period set by the team, and told exactly which symptoms should bring you back. Write those down. The first few nights at home are when people most often wonder whether an ache is normal, and having the list beside the bed answers most of those questions.

Weeks two to six: eating, walking, driving and returning to work

The second week is when the difference between approaches becomes obvious to the person living it. After laparoscopic surgery, most people are walking freely around the house and beyond, climbing stairs and showering unaided, with soreness that fades day by day. After open surgery, walking is still encouraged and possible, but the wound continues to pull on bending, coughing and turning in bed for longer.

Eating follows a staged plan that is identical for both approaches, because the stomach inside is the same. Liquids give way to puréed food, then soft food, then a gradual return to solid textures over several weeks. The NHS recovery guidance for weight-loss surgery describes this progression and stresses that the pace is set by your dietitian, not by how hungry or impatient you feel.

Driving is usually possible once you can perform an emergency stop without hesitation and are no longer taking painkillers that cause drowsiness; the NHS advises checking with your team and your insurer. Desk-based work often resumes within a few weeks. MedlinePlus gives a typical return to normal activity of 3 to 5 weeks after gastric bypass, while heavy lifting and vigorous exercise are usually held back longer, particularly after an open incision where the fascia needs time to regain strength.

Fatigue surprises many people. Rapidly reduced calorie intake, the metabolic work of healing and disrupted sleep combine, and a nap in the afternoon during week three is not a sign of a problem.

Follow-up appointments in this window check wounds, weight, fluid intake and blood tests, and they are the place to raise anything that feels off. Both laparoscopic and open patients need the same long-term monitoring for vitamin and mineral deficiencies, which the NHS describes as a lifelong commitment after these operations.

Which complications change with the approach, and which do not?

It helps to sort risks into two boxes: those that live in the abdominal wall and those that live inside.

Abdominal-wall risks shift with the approach. Wound infection is more likely along a long incision than around small ports, partly because the wound is bigger and partly because it is under more tension. Incisional hernia, which MedlinePlus lists as a risk of gastric bypass, is widely reported to be more common after open surgery. Chest infection and clots, although they are not wound problems, are influenced indirectly, because pain and immobility are their upstream causes.

Internal risks are largely shared. The most serious is a leak from a staple line or a new joint between stomach and intestine, which allows digestive contents into the abdomen and can cause a severe infection. The NHS risks page for weight-loss surgery lists leaks alongside blood clots, wound infection, bleeding and, rarely, death. Bleeding, narrowing at a new joint, gallstones after rapid weight loss, dumping syndrome after bypass (rapid emptying of food into the intestine causing sweating, cramping and faintness) and long-term nutritional deficiency depend on the operation performed, not on how the surgeon got in.

Two honest caveats. First, the camera view can reduce some internal risks by improving visibility, but the evidence for that is less clear-cut than the evidence on wound outcomes. Second, laparoscopy has a small set of its own hazards, including injury to bowel or blood vessels when ports are placed and effects of the gas on circulation under anesthesia; these are uncommon and are managed by experienced teams.

The most useful takeaway is that the decision between approaches is about recovery and the abdominal wall. It is not a decision about whether the operation is safe inside; that safety rests on the team, your preparation and follow-up.

Does keyhole surgery apply to stomach cancer operations too?

Searches about stomach surgery often mix two very different reasons for operating: reshaping a healthy stomach for weight loss and removing part or all of a stomach affected by cancer. The approach question arises in both, but the answers are weighed differently.

Most stomach cancers are adenocarcinomas, meaning they begin in the gland cells of the stomach’s inner lining, the layer that produces acid and mucus. The NHS describes surgery to remove part or all of the stomach as one of the main treatments when the disease has not spread widely. Pathologists further divide adenocarcinoma into types; the “diffuse” type spreads through the stomach wall as scattered cells rather than forming a single lump, which can make it harder to see on scans and at operation and often influences how much stomach the surgeon removes.

Laparoscopic gastrectomy for cancer is performed in many centers, and the recovery advantages are the same ones described throughout this article. The additional considerations are oncological: the surgeon must remove the tumor with a clear margin and take out the surrounding lymph nodes, small glands that filter fluid and are the first place cancer often travels. Whether that can be done as thoroughly through a camera as through an open wound has been studied extensively, and mainstream guidance treats both as acceptable in appropriately selected patients, with the choice resting on tumor stage, location and the surgeon’s expertise.

If your question is about cancer rather than weight loss, the decision framework changes: the priority is complete removal and accurate staging, and recovery speed is weighed against that. Your cancer team, which usually includes a surgeon, an oncologist and a specialist nurse, will explain why they recommend one route over the other for your particular tumor.

What people often get wrong about laparoscopic vs open stomach surgery

“Keyhole is minor surgery.” The incisions are minor; the operation is not. Inside, a laparoscopic sleeve or bypass is exactly as major as the open version, with the same staple lines, the same leak risk and the same lifelong nutritional follow-up. The NHS is clear that weight-loss surgery is a major operation whichever route is used.

“Open surgery is old-fashioned or means something went wrong.” Open surgery is a deliberate, safety-driven choice for particular anatomy or circumstances, and conversion during an operation reflects good judgment rather than error.

“Smaller scars mean faster weight loss.” Weight change depends on the internal operation, on hormones, on eating and on movement. The abdominal wall has no role in it.

“Pain after keyhole surgery is all from the cuts.” A good share of early discomfort is referred pain from the gas irritating the diaphragm, felt in the shoulders. Walking and time relieve it; wound dressings do not.

“I can rest in bed until it stops hurting.” Rest feels intuitive and is the wrong instinct. Immobility drives clots and chest infections after both approaches. Gentle, frequent walking is treatment, not optional activity.

“Once the wounds heal, recovery is over.” Skin heals in a couple of weeks; fascia takes months to regain strength, which is why lifting limits outlast the visible scars, especially after open incisions. The dietary progression and vitamin monitoring continue for life.

“A hernia at the scar is only a cosmetic problem.” Incisional hernias can trap bowel and cause obstruction; a new bulge at any scar that is painful or cannot be pushed back needs prompt assessment.

The thread running through these myths is a tendency to judge an operation by what is visible. The evidence points the other way: the visible part is where laparoscopy helps most, and the invisible part is where the two approaches are the same.

Questions to ask your care team before you decide

A good consultation leaves you knowing not just what is planned but why. These questions are designed to draw out the reasoning behind the approach chosen for you.

• Do you plan to perform my operation laparoscopically, and what about my history or anatomy might make an open approach more likely?
• How often do operations like mine convert to open in your team, and what would prompt that decision during surgery?
• If conversion happens, how will my hospital stay and activity restrictions change?
• What will my incisions look like, and how should I care for them at home?
• What clot-prevention measures will I have in hospital and after discharge, and for how long?
• How will pain be managed on the first day, and what is the plan for reducing stronger painkillers before I go home?
• When can I expect to shower, drive, return to my specific job and lift my children or shopping bags?
• Which warning signs should bring me back to hospital rather than waiting for the next appointment?
• How will you check for an incisional hernia at follow-up, and what should I look for myself?
• Is there anything I should do or stop in the weeks before surgery, such as stopping smoking or adjusting medicines, that would make the laparoscopic route safer?

Bring someone with you if you can, and write the answers down. It is entirely reasonable to ask the same question twice if the first answer used words you did not follow. The team expects it, and a clear understanding of the plan is part of the consent process, not an add-on to it.

One more question is worth asking of yourself: what matters most to you in recovery? For some people it is getting back to a physical job; for others it is the appearance of scars or the length of the hospital stay. Telling the team your priority helps them tailor the explanation, even though the choice of approach itself rests with the surgeon.

When to call your doctor after stomach surgery

Most discomfort after either approach is expected and eases with time, walking and the pain plan you were given. A few signs are different in kind and should not be watched and waited on. Contact your surgical team, or emergency services if you cannot reach them and feel unwell, if you notice any of the following.

• A heart rate that stays fast at rest, particularly with fever, chills or a sense of dread. This combination can be the earliest sign of a leak from a staple line, sometimes before pain becomes severe.
• Abdominal pain that is worsening rather than settling, or pain that spreads to the shoulder and is not relieved by walking or the passing of a day or two.
• Shortness of breath, chest pain, or coughing up blood, which can indicate a clot in the lung or a chest infection.
• Pain, swelling, warmth or redness in one calf or thigh, the typical signs of a deep vein thrombosis.
• Vomiting that will not stop, an inability to keep fluids down for more than a few hours, or signs of dehydration such as very dark urine, dizziness on standing and a dry mouth.
• Vomiting blood or passing black, tarry stools, which suggest bleeding into the digestive tract.
• A wound that becomes increasingly red, hot, swollen or opens up, or that leaks pus or cloudy fluid.
• A new bulge at any incision, especially one that is painful, hard or cannot be pushed gently back in, or a bulge with cramping and vomiting.
• Fever that persists or climbs after the first day at home.

These red flags apply after both laparoscopic and open surgery; the internal complications are shared, and the wound-related ones are simply more likely along a long incision. Your team will have given you a direct number for the first weeks. Using it for a concern that turns out to be nothing is exactly what it is there for, and no surgeon would rather hear about a leak on day five than day two.

Frequently asked questions

Is laparoscopic stomach surgery safer than open surgery?

It is safer for the abdominal wall, with less pain, fewer wound infections and fewer incisional hernias, and those benefits indirectly reduce chest and clot problems by getting people moving sooner. Internal risks such as a staple-line leak or bleeding are broadly similar because the operation inside is the same. The safest approach for any individual is the one the surgeon can perform with clear visibility, which is why open surgery is still chosen in some cases.

How long is laparoscopic surgery recovery time compared with open?

After laparoscopic gastric bypass, MedlinePlus gives a typical hospital stay of 1 to 3 days and a return to normal activity in about 3 to 5 weeks. Open surgery generally means a longer stay and a longer wait before heavy lifting, because the muscle and fascia layers must regain strength. These are typical ranges, not guarantees, and your team will set limits based on your progress and your job.

Is open vs laparoscopic gastric bypass different in how much weight you lose?

No. Weight change depends on the internal anatomy created, on gut hormone changes and on eating and activity habits afterward. The route through the abdominal wall plays no part in it. The comparison between open and laparoscopic gastric bypass is about recovery speed, pain and wound complications, where the small-incision approach has clear advantages, not about the long-term effect of the operation.

Why do my shoulders hurt after keyhole stomach surgery?

The carbon dioxide gas used to create working space irritates the diaphragm, and the nerves supplying the diaphragm share pathways with the shoulder, so the brain registers the ache there. It usually fades within a day or two as the gas is absorbed, and walking helps. Shoulder pain that is worsening, or that comes with fever or a racing heart, should be reported because it can occasionally signal a leak.

When is open surgery needed instead of keyhole?

Surgeons plan an open operation, or warn it is likely, when dense scar tissue from previous surgery, a large abdominal-wall hernia, unusual anatomy or a body shape that limits gas working space would make the camera view unsafe. Some heart or lung conditions also make the gas pressure hard to tolerate under anesthesia. The surgeon may also convert during a laparoscopic operation if bleeding or poor visibility arises.

On which side of the body is the stomach located?

The stomach sits in the upper left part of the abdomen, tucked under the lower ribs and just below the diaphragm, according to Cleveland Clinic. It is J-shaped, with the wider upper part on the left and the narrower outlet curving toward the middle. Its high position is one reason laparoscopic cameras, which can look up under the ribs, are well suited to stomach operations.

What is adenocarcinoma of the stomach, and can it be treated with keyhole surgery?

Adenocarcinoma is cancer that begins in the gland cells of the stomach lining, and it accounts for most stomach cancers. Surgery to remove part or all of the stomach can be performed laparoscopically or open; the choice depends on the tumor’s stage and position and on the need to remove surrounding lymph nodes completely. Recovery advantages of keyhole surgery apply, but complete removal is the first priority for the cancer team.

What is diffuse type gastric adenocarcinoma?

Diffuse type gastric adenocarcinoma spreads through the stomach wall as scattered cells rather than forming a single lump, which can make it harder to see on scans and during surgery. Because its edges are indistinct, surgeons often remove a wider margin, sometimes the whole stomach. The approach, keyhole or open, is decided by the surgical team based on how clearly the extent of disease can be defined.

Will small incisions mean I can skip the walking and breathing exercises?

No. Walking and deep breathing are treatments against clots and chest infection after both approaches. Keyhole surgery makes them easier and less painful, which is one of its main benefits, but the risk of immobility is the same. Most programs expect patients to be sitting up within hours and walking the same or next day, and compression devices or injections may be used alongside movement.

How do I know if a bulge at my scar is a hernia?

An incisional hernia usually appears as a soft bulge at or near a scar that becomes more obvious when standing, coughing or straining and may flatten when lying down. It is more common after open incisions but can occur at laparoscopic port sites. Any bulge that is painful, hard, cannot be pushed back gently, or comes with vomiting or cramping needs urgent assessment because bowel can become trapped.
