Abstract

Background

First performed in 1992, the side-to-side isoperistaltic strictureplasty (SSIS) is a bowel-sparing surgical option for Crohn’s patients presenting with sequentially occurring stenoses over long intestinal segments (>15 cm). This investigation was designed to study the outcomes and patterns of recurrence after a SSIS.

Materials and methods

Between 1992 and 2003, 30 patients underwent SSIS at the University of Chicago. Their data were gathered prospectively in an Institutional Review Board-approved database.

Results

A total of 31 SSISs were constructed in 30 patients. As an indication of the severity of disease in these patients, 25 of 30 (83%) required a concomitant bowel resection, and 13 (43%) underwent at least one additional strictureplasty. The average length of diseased bowel used to construct the SSIS was 51 cm. The average length of residual small bowel after performance of SSIS was 275 cm, and the SSIS represented an average 19% of the remaining small bowel that would have otherwise been sacrificed with resection. Three patients experienced perioperative complications (10%) and one died (3%). Seven patients (23%) required reoperation to treat recurrence of symptoms within the first 5 years. In four of these patients, recurrence was found at or near the previous SSIS.

Conclusions

A side-to-side isoperistaltic strictureplasty (SSIS) is a safe and effective surgical option for sequentially occurring Crohn’s strictures over long intestinal segments.

Introduction

Multiple, repeated, or massive resections of the small bowel are associated with an increased risk of short-gut syndrome in Crohn’s disease patients. Side-to-side isoperistaltic strictureplasty (SSIS) has recently emerged as a bowel-sparing surgical alternative to resection in the treatment of extensive Crohn’s disease [1]. SSIS is distinct from other conventional strictureplasties (Heineke-Mikulicz, Finney), in that it can be used to treat very long (>15- to 20-cm) segments of disease with multiple sequential strictures by performing a longitudinal enterotomy and subsequent side-to-side enteroenterostomy. In so doing, SSIS widens the diameter of the diseased bowel without sacrificing any mucosal absorptive area.

Background

Crohn’s disease is a chronic inflammatory bowel disease of unknown etiology and with no known cure. Although it may present anywhere from the mouth to the anus, Crohn’s disease has a propensity for involvement of the small and large bowel [2]. There it manifests its cardinal pathology of mucosal ulceration and transmural inflammation. Chronic inflammation of the bowel wall may lead to intestinal strictures and bowel obstruction in its advanced forms [3].

Crampy, intermittent abdominal pain is

Data management and case identification

Data were assembled from the Crohn’s disease protocol and database of the Section of General Surgery, University of Chicago. The Crohn’s disease protocol and database is an Institutional Review Board-approved methodology for gathering prospective data on Crohn’s patients undergoing surgery. It involves two distinct data collection periods. Preoperatively, the patient is interviewed by the operating surgeon and a nurse clinician specialized in the management of inflammatory bowel disease. During

Results

Patients presented with a host of symptoms before surgery, most of which (87%) were obstructive in nature (Fig. 5). In addition, 28 of 41 (68%) primary indications for surgery were related to some degree of intestinal obstruction; other indications included failure of medical management (8 cases), fistula repair (2 cases), and hernia repair, resection of excluded bowel, and gastrointestinal hemorrhage (1 case each).

A total of 31 SSISs were constructed; of these, 20 (64%) were constructed with

Discussion

Strictureplasty was first proposed by Katariya et al. as a means to treat ileal strictures secondary to intestinal tuberculosis [14]. Stimulated by this concept, Lee and Papaioannou began using strictureplasty to treat fibrostenotic strictures in Crohn’s disease in the late 1970s [11]. The guiding principle behind the use of strictureplasty was that obstructive symptoms resulting from Crohn’s disease could be ameliorated without resection, thus reducing the risk of short-gut syndrome. This aim

    These interventions are indicated for the treatment of stenosis, especially when these are very extended or multiple, and when they arise in patients who had already undergone previous bowel resections. Furthermore in the case of multiple stenosis a strictureplasty can be usefully combined with a resection, during the same surgical procedure, to reduce the extent of surgical demolition.1,11,12,60,143 It has been repeatedly called attention to the fact that strictureplasty interventions, leaving in situ sections of affected bowel, may favor the onset of cancer.144
