Outcomes of Different Surgical Procedures After High Level Resection for Patients With Small Intestinal Gangrene

January 3, 2025 updated by: Mohamed Mohamed Shendy Abdelsayed, Assiut University
In this cohort study, aim to evaluate and compare short-term postoperative outcomes of different surgical procedures for patients with intestinal gangrene who underwent high level small bowel resection (< 150 cm from DJ).

Detailed Description

Patients with intestinal gangrene have a high mortality rate depending on etiology, degree, and length of an ischemic part, associated comorbidity, and time between the onset of symptoms and final diagnosis. This overall mortality ranges from 50 to 80%. When intestinal gangrene is evident or suspected, surgical laparotomy is mandatory, where the affected segment is resected, and the remaining part is either anastomosed or diverted on the anterior abdominal wall as stoma.

Small bowel anastomoses performed in the emergency settings have a high risk of anastomotic leakage. The leak rate in these settings may reach 35% . Intestinal gangrene is usually associated with peritonitis and sepsis. The performance of ostomy or intestinal anastomosis in cases of peritonitis or sepsis is a controversial theme. This controversy increases when proximal small bowel is involved .

Stomas avoid the risks of anastomotic leakage and re-operation and permit close examination of the bowel by inspection. However, creating stoma after proximal level of resection is associated with catastrophic sequels of high output fistula and short bowel syndrome. Hence, most of the time the risk of a high jejunal anastomosis dehiscence is preferred to the metabolic complications associated with ostomy .

A jejunostomy was defined as having less than 200 cm of proximal remaining small bowel. Since most nutrients are absorbed within the first 100-150 cm of the jejunum, the severity of short bowel syndrome and dependence on TPN is markedly increased if a jejunostomy is created at less than 150 cm from DJ . Distal refeeding of chyme "re-feeding enteroclysis", by reinfusing the chyme collected from the proximal stoma into the downstream small bowel through the distal stoma, was used by some surgeons to alleviate the complications of jejunostomy before re-establishment of digestive continuity . However, this procedure can be technically demanding. On the other hand, some authors prefer to use prophylactic tube enterostomy with primary anastomosis in cases of high risk of anastomotic leak .

The choice between these surgical technical varieties depends upon general health status of the patient, and local abdominal factors e.g. presence of peritoneal contamination, but mostly depends on surgeons' experience.

Contacts and Locations

This section provides the contact details for those conducting the study, and information on where this study is being conducted.

Study Contact

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Sampling Method

Non-Probability Sample

Study Population

This study is a prospective non-randomized comparative study. Patients who will undergo high level small bowel resection for intestinal gangrene during the period from September 2024 to September 2026 are included.

Description

Inclusion Criteria:

  • 1) Distance of proximal resection margin less than 150 cm from DJ. 2) Mesenteric vascular ischemia. 3) Strangulating obstruction e.g. due to hernia, volvulus, band, etc.

Exclusion Criteria:

  • 1) Patients less than 18 years. 2) Patients with malignant disease. 3) Patients with almost all small bowel loops resected (< 60 cm remaining).

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Group A: Primary anastomosis: using hand sewing technique
Group B: Primary anastomosis with prophylactic tube enterostomy. Feeding jejunostomy may be inserted
Group C: Jejunostomy: double barrel stoma.
Group D: Jejunostomy: double barrel stoma with distal refeeding via the mucous fistula opening.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Study Major Dates

Study Start (Estimated)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
