Background:
A modified Michelassi strictureplasty over the ileocaecal valve or ileocolic anastomosis could be an alternative to ileocaecal resection. This study assessed the outcome of the modified Michelassi strictureplasty in patients with extensive stenotic terminal ileal Crohn's disease [CD].
Methods:
This type of strictureplasty was proposed to all patients with an extensive strictured [neo-] terminal ileal segment [> 20 cm]. Short- and long-term outcome data were retrieved from a prospectively maintained database. Safety and medium-term efficacy were studied, using both postoperative magnetic resonance enterography [MRE] and ileocolonoscopy at 6 months.
Results:
Between June 2009 and September 2014, 29 CD patients had a modified strictureplasty [male 9/29, median age 38 [range: 16-64] years]. The median length of strictureplasty was 50 [27-110] cm. Twelve patients underwent a total of 30 additional procedures during surgery, mainly additional short strictureplasties, but also segmental resections. The majority had a laparoscopic-assisted procedure. Median length of hospital stay was 9 [6-17] days. Two patients had an early rescue procedure to oversew a small anastomotic leak. MRE and ileocolonoscopy at follow-up showed a remarkable regression of inflammation and bowel wall thickness. Clinical recurrence, necessitating initiation or modification of medical therapy, and surgical recurrence were reported in 11 and 1 patient after a median follow-up of 21 [1-54] months, respectively.
Conclusion:
A modified long Michelassi strictureplasty appears to be safe in patients with extensive stricturing Crohn's ileitis. Significant mucosal and bowel wall healing is observed and suggests that clearance of microbial stasis may play a role in this process.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
