Abstract
Abstract Background Stapled anastomosis is the most common anastomotic method after ileocolic resection for Crohn's disease, whereas handsewn end-to-end (HS-ETE) anastomosis is less frequently performed. The optimal technique for ileocolic anastomosis in Crohn's patients remains controversial. Some studies have suggested potential benefits of HS-ETE over SSTS, including lower recurrence rates, whereas others have found no difference. We aimed to compare short-term postoperative outcomes and long-term recurrence-free survival between the HS-ETE and SSTS groups at our center. Methods This retrospective study included consecutive patients who underwent ileocolic resection for Crohn's disease between 2012-2022 with either HS-ETE or SSTS anastomosis. The primary outcomes were perianastomotic recurrence and need for surgical/endoscopic intervention. Cox regression and Kaplan-Meier curves were used to compare recurrence-free survival. Results A total of 764 patients were included: 162 (21%) with HS-ETE and 602 (79%) with SSTS anastomosis. The median age of the HS-ETE and SSTS groups was 39 and 38 years, respectively. Males comprised 43% of the HS-ETE group and 51% of the SSTS group. The median BMI was 24 kg/m2 in both groups. The HS-ETE group had a longer median disease duration (10 vs. 7 years, p=0.02) and a higher rate of previous abdominal surgery (35% vs. 22%, p=0.01) than the SSTS group did. The ileocolonic location (78% vs. 66%, p=0.03) and perforating disease (45% vs. 35%, p=0.04) were also more common in the HS-ETE group. The median operative time (207 min vs. 147 min, p<0.001) and estimated blood loss (150 mL vs. 75 mL, p<0.001) were greater in the HS-ETE group. There were no differences in 30-day outcomes between the groups. Perianastomotic recurrence rates were similar between the HS-ETE and SSTS groups (29.6% vs. 28.9%, p=0.93). The 5-year recurrence-free survival rates were also comparable (HS-ETE, 56.4% vs. SSTS, 59%; p=0.94). Also, we found that the risk of requiring surgical or endoscopic intervention for recurrence between HS-ETE and SSTS was comparable (HS-ETE, 65.2% vs. SSTS, 74.2%; p=0.273) Conclusion Although the HS-ETE group had worse baseline disease characteristics, including longer disease duration, higher previous surgery rates, and more aggressive disease location and behavior, HETE and SSTS anastomosis after ileocolic resection for Crohn’s disease yielded comparable perioperative and long-term outcomes in our patient cohort.
