Recurrent volvular herniation of the ileal pouch: a case report and literature review

Volvulus of the ileal pouch-anal anastomosis: a meta-narrative systematic review of frequency, diagnosis, and treatment outcomes

Background

Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice for medically refractory ulcerative colitis and familial adenomatous polyposis. While rare, a pouch volvulus can occur. We aimed to determine the frequency, presentation, and management approach of pouch volvulus in patients with IPAA.

Methods

A systematic search of published literature was performed by a medical reference librarian on 10 August 2018 and two independent reviewers identified relevant publications, extracted data, and assessed the methodological quality based on a validated tool. A retrospective review of the Mayo Clinic electronic medical records identified one case of pouch volvulus between January 2008 and August 2018.

Results

The frequency of pouch volvulus from one large published study reporting long-term outcomes of IPAA was 0.18% (3/1,700). A total of 22 patients (18 ulcerative colitis) were included (median age 32 years, 73% females). Median time to volvulus after IPAA was 36 months while median interval to volvulus diagnosis from symptom onset was 24 hours. Abdominal pain was the most commonly reported symptom (76%). The diagnosis was made primarily by abdominal computed tomography (13/17 patients, 76%). Endoscopic treatment was successful in 1 of 11 patients (9%). Surgery was performed in 20 patients and pouch-pexy and pouch excision were the most frequent surgical operations. A redo IPAA was performed in five patients (25%).

Conclusion

Pouch volvulus is a rare but serious complication of IPAA and should be suspected even in the absence of obstruction symptoms. Endoscopic treatment often fails and surgery is effective when performed early.

Surgical Management of an Ileal J-Pouch-Anal Anastomosis Volvulus

BACKGROUND

A restorative proctocolectomy with an IPAA is the surgical treatment of choice for medically refractory ulcerative colitis. Until now, a pouch volvulus has been considered a rare complication, only described in case reports and small case series. The aim of this technical note was to develop a standardized approach to allow a minimally invasive treatment.

TECHNIQUE

First, an endoscopic decompression of the pouch is attempted. Subsequently, an exploratory laparoscopy is performed. If the endoscopic decompression was successful, a complete laparoscopic reduction is feasible. Once the integrity of the pouch is confirmed, a bilateral pouchopexy is performed, using multifilament interrupted sutures. Finally, the pouch patency is tested by pouchoscopy.

RESULTS

Between December 2010 and December 2018, 151 minimally invasive restorative proctocolectomies with an IPAA were performed. Eighty-nine IPAAs were constructed with the mesentery positioned anteriorly, 35 posteriorly, and 27 on the right side. Three patients were diagnosed with an IPAA volvulus. All 3 of the patients were in the anterior group (3.4%) compared with 0 patients in the nonanterior group. One patient (33%) was treated laparoscopically, after a successful endoscopic reduction. In the other 2 cases, conversion to a laparotomy was needed because an endoscopic decompression could not be achieved.

CONCLUSION

An endoscopic decompression was required to allow a laparoscopic treatment, and a bilateral pouchopexy was needed to avoid recurrence. This standardized approach might be a good treatment option, and we are awaiting additional follow-up to determine its long-term durability. In addition to the already described risk factors (minimally invasive technique, female sex, and low BMI), an anterior positioning of the pouch mesentery might be a potential risk factor as well for pouch volvulus. However, these observations should be carefully interpreted, considering the small number of cases.

Mesh Migration into the J-Pouch in a Patient with Post-Ulcerative Colitis Colectomy: A Case Report and Literature Review

Mesh repair offers advantages like lower postsurgical pain and earlier return to work. Thus, it has become a widely used treatment option. Here, we present the first case report of a mesh migration into a J-pouch in a patient with history of ulcerative colitis who underwent total abdominal colectomy with J-pouch and ileoanal anastomosis and a subsequent laparoscopic ventral hernia repair with mesh.
