Percutaneous endoscopic sigmoidopexy using T-fasteners for management of sigmoid volvulus

Laparoscopic fixation of volvulus by extra-peritonealization: a case series

BACKGROUND

Volvulus is one of the leading causes of colonic obstruction with a high recurrence rate following endoscopic decompression. Although colonic resection remains the treatment of choice, it is often associated with significant morbidity and mortality, especially in elderly patients. Colonic fixation with extra-peritonealization has been suggested as an alternative to colonic resection. The aim of this study was to evaluate the surgical outcomes of patients with colonic volvulus in our initial experience with this procedure.

METHODS

A retrospective analysis of a prospectively maintained database of all patients who underwent colonic extra-peritonealization for volvulus between January 2016 and April 2021 in Sheba medical center (Ramat-Gan, Israel) was performed. Patients' demographics, clinical, peri-operative and post-operative data were recorded and analyzed.

RESULTS

One hundred and thirty nine patients were admitted due to acute colonic volvulus, 48 of whom were treated surgically. Eleven patients underwent extra-peritonealization of the sigmiod or cecum during the study period. Mean age was 64.5 years. Six patients (54.55%) were males. Seven patients (63.63%) presented with sigmoid volvulus and 4 (36.36%) with cecal volvulus. Median American Society of Anesthesiologists (ASA) class was 3 (range 2-4). One patient (9.09%) was required urgent surgery. The majority of patients was operated on using a laparoscopic approach (10 patients, 90.9%). Median length of stay was 3 days (range 1-6 days) and no post-operative complications or readmissions within 30 days after surgery were recorded. Median length of follow-up was 283 days (range 21-777 days). During the follow-up period, three patients (27.27%) presented with recurrent volvulus and required an additional surgical intervention with colonic resection. Of the patients with volvulus recurrence, one patient (9.09%) required an urgent surgical intervention.

CONCLUSIONS

Extra-peritonealization of colonic volvulus is feasible and safe. Although recurrence rates are fairly high, the low morbidity associated with the procedure makes it an appealing alternative to colonic resection, especially in patients with high risk for post-operative complications.

American Society for Gastrointestinal Endoscopy guideline on the role of endoscopy in the management of acute colonic pseudo-obstruction and colonic volvulus

Colonic volvulus and acute colonic pseudo-obstruction (ACPO) are 2 causes of benign large-bowel obstruction. Colonic volvulus occurs most commonly in the sigmoid colon as a result of bowel twisting along its mesenteric axis. In contrast, the exact pathophysiology of ACPO is poorly understood, with the prevailing hypothesis being altered regulation of colonic function by the autonomic nervous system resulting in colonic distention in the absence of mechanical blockage. Prompt diagnosis and intervention leads to improved outcomes for both diagnoses. Endoscopy may play a role in the evaluation and management of both entities. The purpose of this document from the American Society for Gastrointestinal Endoscopy's Standards of Practice Committee is to provide an update on the evaluation and endoscopic management of sigmoid volvulus and ACPO.

Outcomes of first-line endoscopic management for patients with sigmoid volvulus

BACKGROUND

Sigmoid volvulus is a common cause of colonic obstruction in old and frail patients. Its standard management includes the endoscopic detorsion of the colonic loop, followed by an elective sigmoidectomy to prevent recurrence. However, these patients are often poor candidates for surgery.

AIM

The aim of this study was to compare death rate between elective sigmoidectomy and conservative management following endoscopic detorsion for sigmoid volvulus.

METHODS

The medical records of 83 patients undergoing endoscopic detorsion of a sigmoid volvulus from 2008 to 2014 were retrospectively reviewed. Patients were divided into two groups: 'elective surgery' and 'no surgery'.

RESULTS

Patients in the 'no surgery' group (n = 42) were older and had more loss of autonomy than in the 'elective surgery' group. Volvulus endoscopic detorsion was successful in 96% of patients with no complications. The median follow-up was 13 months (1 day-67 months). The death rate was 62% in the 'no surgery' group versus 32% in the 'elective surgery' group (p = 0.02). In the 'no surgery' group, 23/42 of patients had volvulus recurrence. No recurrence occurred after surgery.

CONCLUSION

Elective surgery must be planned as soon as possible after the first episode of sigmoid volvulus. In frail patients, other options must be developed.
