The optimal surgical approach to extensive Crohn’s disease (CD) terminal ileitis is debated. To date, no studies have directly compared the short- and long-term outcomes of modified side-to-side isoperistaltic strictureplasty over the valve (mSSIS) to traditional ileocecal resection.
A retrospective, observational, comparative study was conducted in consecutive CD patients operated for extensive involvement of the terminal ileum (≥ 20 cm). Ninety-day postoperative morbidity was assessed using the comprehensive complication index (CCI). Surgical recurrence was defined as the need for any surgical intervention related to CD during the follow-up period. Endoscopic remission was defined as ≤ i2a, according to the modified Rutgeerts score. Deep remission was defined as the combination of endoscopic remission and absence of clinical symptoms. Perioperative factors related to clinical recurrence were evaluated.
Eighty-seven patients were included (47 (54%) ileocecal resection and 40 (46%) mSSIS). Median follow-up was 56 (IQR 34.7–94.4) and 72 (IQR 48.3–87.2) months for resection and mSSIS, respectively (p < 0.001). No mortality occurred. Mean CCI was 9.1 vs 8.5 for ileocecal resection and mSSIS, respectively (p = 0.48). Throughout the follow-up, 8 patients in the resection group (17%) and 5 patients in the mSSIS group (12.5%) experienced surgical recurrence (p = 0.393). Thirty-seven (92.5%) of patients kept the mSSIS. No difference in deep remission was observed (41% vs 22.5%, p = 0.34).
Modified SSIS seems to be non-inferior in terms of safety, recurrence, and durability to traditional resections with the advantage of mitigating the risk of a short bowel syndrome. Larger prospective studies are required to confirm these findings.
