Abstract

Aim: To assess the outcomes following several kinds of local repairs for stoma prolapse to determine the optimal local prolapse repair procedure.

Methods: Thirty-seven patients (24 men, median age: 63 years, range: 33 years to 88 years) undergoing 45local repairs were prospectively registered, and their medical records were retrospectively reviewed in characteristics of patients and stoma, operative outcomes, and recurrence.

Results: Stapler repair with anastomosis was performed in 26 repairs, button-pexy fixation in 12 repairs, fascia fixation in 4 repairs, stapler closure in 2 repairs, and modified Gant-Miwa procedure in one repair. The selection criteria for the procedure were different in each repair. The operative time and bleeding volume were acceptable in all procedures without mortality. Postoperative morbidities were few and not serious. Recurrence of stoma prolapse after stapler repair with anastomosis, button-pexy fixation, fascia fixation, and stapler closure occurred in 3.8%, 41.7%, 50% and 0% of repairs, respectively, during a median follow-up period of 13months (range: 1 month to 120 months). Stoma closure after repair and emergent surgery for stoma prolapse were performed in 5 (13.5%) and 3 (8.1%) of 37 patients, respectively.

Conclusion: The selection of repair method might depend on the patients’ general conditions, expected survival period, and possibility of stoma reversal. Button-pexy fixation maybe used for transient stoma. Otherwise, stapler repair with anastomosis or closure can be an option for prolapse repair according to the condition of stoma.

Introduction

Stoma prolapse is a complication occurring in 2% to 26% of patients after stoma creation, and it often disturbs the quality of life of patients with stoma [1-4]. The prolapse can mostly be managed conservatively by Wound, Ostomy, and Continence (WOC) nurses [5-7]. When complications by stoma prolapse make stoma care by WOC nurses difficult and/or the stoma prolapse affected the normal bowel functioning, surgical managements can be considered. If stoma functions as a faecal diversion, stoma prolapse is resolved by stoma reversal.

The surgical approach for stoma prolapse repair can be broadly classified into the abdominal approach, which is often via a midline laparotomy, and the local approach around the stoma [8]. The abdominal approach is more invasive and requires induction of general anesthesia, although there are recent reports of abdominal procedures being performed laparoscopically [9,10]. The local approach is considered a less invasive procedure. Several procedures have been reported as local approaches, including button pexy fixation [11-13], conventional method [8], repairs similar to the Altemeier’s procedure [14], Delorme operation [15,16] and Miwa-Gant method [17], stapler technique [18-25] and mesh strip technique [26]. However, studies on the outcomes after operative repair of a stoma prolapse are scarce and the lack of comparative data and short-term follow-up have made choosing the optimal correction method for stoma prolapse difficult. Even in a recent report, the largest number of analyzed patients who underwent repair with abdominal and local approaches was 23 [8]. We therefore aimed to assess the outcomes of several local repairs for stoma prolapse in our institution and clarify the selection criteria for choosing the appropriate local repair procedure for stoma prolapse.

Materials and Methods

Ethical information

The protocol of this study was approved by the institutional review board of Fujita Health University and performed in accordance with the 1964 World Medical Association’s Declaration of Helsinki and its later amendments. All patients gave their written informed consent prior to inclusion in the study.

Patient population and study design

This retrospective observational cohort study was conducted in the colorectal division of a single hospital. Thirty-seven patients who underwent local repairs for stoma prolapse between December 1997 and April 2020 were prospectively registered, and their medical records were retrospectively reviewed. The characteristics of patients and stoma, operative outcomes, and recurrence of stoma prolapse in each local repair procedure were investigated.

Operative procedures

Button-pexy fixation was performed according to the procedure described by Canil, et al. and Katsuno, et al. [11,13] After identifying the fixation point from the limb of the stoma by using the fingers, followed by injection of local anesthesia into the skin, two straight needles with 2-0 non-absorbable threads attached a standard round-edged laboratory coat button were passed through the bowel wall and anterior abdominal wall. Another button was fitted with the threads at the skin side of the abdomen, and the threads were tied to properly fix the limb of the stoma to the abdominal wall.

Stapler repair with anastomosis was done according to the procedure described by Maeda, et al. and Masumori, et al. [18,24] After pulling out the prolapsed stoma with Babcock forceps as long as possible, the prolapsed stoma was vertically divided using a stapler (GIA 60; Covidien, Tokyo, Japan or PCEE60A; Ethicon, Tokyo, Japan) down from 1 cm to 2 cm above the skin level. Then, the prolapsed stoma was divided horizontally and circumferentially at 1 cm to 2 cm above the skin level.

Simple excision and closure of a distal limb of a loop stoma prolapse with a stapler device (Stapler closure) was performed according to the procedure reported by Masumori, et al. [22] After grasping and lifting the prolapsed distal limb of the stoma with two Babcock forceps, a stapler (GIA™ 80-4.8 stapler; Covidien, Mansfield, MA, USA) was used in the distal limb of the prolapsed stoma at 1 cm to 2 cm above the skin level and then fired.

Fascia fixation was performed as a modified procedure of button-pexy fixation without using a button. A curved needle with 0-absorbable thread was passed from the inside of the proximal limb of stoma through the bowel wall, abdominal fascia, and bowel wall into the stoma lumen, and then a suture was tied without a button. Six to 8 stitches were made in the proximal limb of stoma.

The modified Gant-Miwa procedure was performed according to the procedure for rectal prolapse [27] described by Furumoto, et al. [17] Mucosal plication of the prolapsed bowel was performed to shorten the prolapsed bowel length.

Criteria for prolapse repair and procedure selection

Stoma prolapse repair was indicated for stoma prolapse with a length of >5 cm, stoma prolapse causing difficulty in stoma care by WOC nurses, and/or for stoma prolapse affecting normal bowel functioning.

The button-pexy fixation was selected for patients with poor general conditions and/or expected short-term survival and stoma reversal. Stapler closure was indicated in patients with irreducible loop stoma prolapse of the distal limb, when no decompression was required in the distal limb of the stoma. Fascia fixation was principally performed for the proximal limb of ileostomy prolapse. The modified Gant-Miwa procedure was used in patients with poor general conditions and expected short-term survival after button-pexy fixation failure. Otherwise, stapler repair with anastomosis was selected to maintain the continuity of the intestine by excising and anastomosing the prolapsed stoma.

Criteria for recurrence and follow-up period

Recurrence of stoma prolapse was defined as a stoma prolapse with a length of >5 cm that developed at the initial repair site. Follow-up period of each procedure was determined from the repair date to the last follow-up date or next repair date. The median follow-up period of all patients was 13 months (range 1 month to 120 months).
