A modified side-to side isoperistaltic strictureplasty over the ileocecal valve could be a valid alternative for ileocecal resection in patients with Crohn's disease (CD) and a long involved ileal segment. We explored the safety and efficacy in a prospective group of patients.


All CD patients with a long stenotic terminal ileum (>25cm) were included. Early ileocolonoscopy and magnetic resonance enterography (MRE) were performed to assess healing. Data were retrieved from a prospectively maintained institutional IBD database.


Between June 2009 and September 2014, 29 patients, with a median age of 38 years (range: 16 - 68) and a median disease duration of 8 years (range: 0 - 34) underwent surgery. Nine male patients were included. Eleven patients were active smokers. Twenty six patients had primary surgery with a strictureplasty over the ileocecal valve. Three patients had a strictureplasty over the ileocolic anastomosis after previous ileocecal resection. Most patients had a laparoscopic approach (n = 24). The median length of the strictureplasty was 50cm (range: 27 - 110). 12 patients had 29 additional procedures: 22 strictureplasties, 6 segmental small bowel resections and 1 reversal of Hartmann's resection. Median length of stay was 9 days (range: 6 - 17) with prolonged postoperative ileus being the main cause of delayed discharge (median: 5 days, range: 2 - 12). Two patients developed a leak requiring additional suturing with successful salvage of the strictureplasty. Twenty-four patients underwent a postoperative colonoscopy at a median follow up of 6 months (range: 2 - 21) with significant improvement of the 'simple endoscopic score in Crohn's disease (SES-CD score). Postoperatieve MRE at a median interval of 6.7 months (range: 2 - 27) showed a significant regression of inflammation, bowel wall thickness and adequate luminal patency. At a median follow up of 10 months (range: 1 - 47), clinical recurrence was reported in 10 patients at a median interval of 14 months (range: 4 - 28). One patient had a surgical recurrence requiring additional strictureplasty after 48 months. Another patient needed adhesiolysis for small bowel obstruction.


A modified long side-to-side isoperistaltic strictureplasty over the ileocecal valve represents a valuable bowel sparing technique in Crohn's disease patients with a long stenotic segment. Surgery is safe and efficient at medium term follow-up.
