Exteriorisation of Bowel Loops

Bowel loop exteriorization surgery

Bowel loop exteriorization surgical procedure is a medical operation where a piece of intestine (loop) is exposed to the surface of the abdomen through a hole in the abdominal wall. This forms a temporary or permanent stoma to enable the intestinal contents to leave the body bypassing a diseased, injured or healing section of the bowel.

What is it also called?

• Loop stoma
• Loop colostomy (when colon is employed)
• Loop ileostomy (when small intestine is employed)
• Bowel loop exteriorization.

What is the Rationale of Bowel Loop Exteriorization?

It is an operation that is usually carried out to:

• Decongest intestinal obstruction.
• Treat perforation or peritonitis.
• Secure a terminal bowel anastomosis.
• Prevent fecal contamination of sepsis.
• Treat bowel ischemia or trauma.
• Short-term diversion of stool in cancer or inflammatory bowel disease.

Bowel Loop Exteriorization Categories

Loop Ileostomy

• Diffuses via the small intestine (ileum).
• Product is liquid to semi-liquid.
• Increased fluid and electrolyte depletion.

Loop Colostomy

• Utilizes the large intestine (colon).
• Output is more formed
• Easier long-term stoma care

Bowel Loop Exteriorization Advantages

• Quick management of contamination.
• Saving of lives during emergencies.
• Guards against distal bowel repair.
• Allows preoperative healing along with the subsequent definitive surgery.

Primary exteriorized bowel repair

Primary exteriorized bowel repair, a surgical intervention, is one in which a diseased or damaged section of bowel is repaired (sutured/anastomosed) and then extended out through the stomach wall rather than remaining entirely in the abdomen. The bowel that has been repaired is temporarily exteriorised in order to have a closer look and also to minimize the chances of contamination of the abdomen in case of leakage.

What is it also known as?

• Exteriorized bowel repair
• Exteriorized anastomosis
• Plastic exteriorization of bowel rivage.

What is the Rationale behind Primary Exteriorized Bowel Repair?

This approach is chosen when:

• Risk of anastomotic leak is great.
• This is gross contamination or peritonitis.
• Patient is haemodynamically unstable.
• Viability of bowel is marginal.

Emergency surgery for:

• Intestinal perforation
• Abdominal trauma
• Typhoid or tuberculous perforation.
• Ischemic bowel
• Neonatal bowel perforation

Advantages

• Less risk of intra-abdominal lethal leak.
• Eliminates or minimizes the necessity of the stoma.
• Maintains bowel continuity
• Applicable in the emergency scenarios of high risk.

Bowel exteriorization procedure

Bowel exteriorization is a surgical procedure where the end of the intestine is exteriorized through the abdominal wall. It is done as either temporary or permanent to deviate intestinal contents, to cover a bowel repair, or to closely observe bowel viability in dangerous cases.

Bowel Exteriorization types

Loop Exteriorization (Stoma Formation)

• Loop ileostomy/loop colostomy.
• Bowel is opened to provide fecal diversion.

End Exteriorization

• End ileostomy or colostomy
• There is exteriorization of one end of bowel.

Exteriorized Primary Repair

• Bowel is sutured yet not perforated.
• Out of the case and under observation.

Procedure

• Anaesthesia is provided in form of general anaesthesia.
• Abdominal probe to examine pathology.
• Choice of healthy bowel segment.
• Abdominal wall opening creation.
• Bowel segment exteriorization.
• Obsession with skin that contains sutures.
• Stoma formation (where diversion is needed)
• Use of stoma bag or sterile dressing.
• Operating time: 45 to 120 minutes 

Postoperative Care

• Observe bowel movements and stool.
• Oral feeding reintroduction.
• Stoma education (where necessary)
• Fluid and electrolyte management.
• Infection prevention

Conclusion

Bowel exteriorization is a useful and frequently life-saving surgical intervention in the case of emergency and high-risk cases of the abdomen. Surgeons can regulate contamination, bowel repair, viability, and minimize the potential disaster of intra-abdominal catastrophe by taking a section of bowel outside of the abdominal cavity. When it is done as a stoma, loop exteriorization, or exteriorized primary repair, it will enable a safer, staged method of managing a patient; particularly when the patient is in sepsis, suffering some kind of trauma, perforation, or even with poor bowel health. Bowel exteriorization may enhance survival, bowel continuity, and in most cases, a subsequent restoration of normal bowel functions with appropriate patient selection, care, and meticulous surgical practice as well as good postoperative care.

FAQ

1. Is exteriorization of the bowel equivalent to a stoma?

• Not always. All stomas entail exteriorization of the bowel but other exteriorizations of the bowel (like exteriorized primary bowel repair) do not expose the bowel but only observe and are performed on safety grounds.

2. What is the rationale behind bowel exteriorization rather than the primary anastomosis?

• It is desirable where the risk of an anastomotic leak is great, like in sepsis, peritonitis, bowel poor condition, malnutrition or hemodynamic instability.

3. Does it have temporary or permanent bowel exteriorization?

• Most cases are temporary. Permanent exteriorization is only carried out in case bowel continuity is no longer safe to restore.

4. What is the time when bowel exteriorization can be reversed?

• This is typically reversed after 6-12 weeks when the patient is free of infection and his condition has become stable.

5. Will the patient have normal stool?

• In stoma cases: the stool comes out through the stoma.
• In exteriorized repair: stool can pass normally anus in case of a repair intact.

6. Can exteriorisation done in children?

• Yes. It is typically performed in emergency situations of neonatology or pediatrics, such as intestinal perforation or necrotizing enterocolitis.
