Stoma associated complications after diverting loop ileostomy, end ileostomy or split stoma formation after right sided colectomy-a retrospective cohort study (StoComSplit Analysis).

BACKGROUND: For high-risk patients receiving right-sided colectomy, stoma formation is a safety strategy. Options are anastomosis with loop ileostomy, end ileostomy, or split stoma. The aim is to compare the outcome of these three options. METHODS: This retrospective cohort study included all patients who underwent right sided colectomy and stoma formation between January 2008 and December 2021 at two tertial referral centers in Switzerland. The primary outcome was the stoma associated complication rate within one year. RESULTS: A total of 116 patients were included. A total of 20 patients (17%) underwent primary anastomosis with loop ileostomy (PA group), 29 (25%) received an end ileostomy (ES group) and 67 (58%) received a split stoma (SS group). Stoma associated complication rate was 43% (n = 21) in PA and in ES group and 50% (n = 34) in SS group (n.s.). A total of 30% (n = 6) of patients in PA group needed reoperations, whereas 59% (n = 17) in ES and 58% (n = 39) in SS group had reoperations (P = 0.07). Wound infections occurred in 15% (n = 3) in PA, in 10% (n = 3) in ES, and in 30% (n = 20) in SS group (P = 0.08). A total of 13 patients (65%) in PA, 7 (24%) in ES, and 29 (43%) in SS group achieved stoma closure (P = 0.02). A total of 5 patients (38%) in PA group, 2 (15%) in ES, and 22 patients (67%) in SS group had a stoma-associated rehospitalization (P < 0.01). CONCLUSION: Primary anastomosis and loop ileostomy may be an option for selected patients. Patients with end ileostomies have fewer stoma-related readmissions than those with a split stoma, but they have a lower rate of stoma closure. CLINICAL TRIAL REGISTRATION: Trial not registered.

Reversal Surgery for Split Stoma with Peristomal Incision is Associated with Improved Postoperative Outcome in Patients with Crohn's Disease.

BACKGROUND: Temporary stoma formation is common in Crohn's disease (CD), while stoma reversal is associated with postoperative morbidity. This study aimed to evaluate the postoperative outcomes of split stoma reversal, SSR (i.e., exteriorization of proximal and distal ends of the stoma through a small common opening) and end stoma closure, ESC (i.e., the proximal stump externalized, and distal end localized abdominally. METHODS: Patients with CD who underwent stoma reversal surgeries between January 2017 and December 2021 were included. Demographic, clinical, and postoperative data were collected and analyzed to evaluate outcomes of reversal surgery. RESULTS: A total of 255 patients who underwent stoma reversal surgeries met the inclusion criteria. SSR was superior to ESC in terms of operative time (80.0 vs. 120.0, p = 0.0004), intraoperative blood loss volume (20.0 vs. 100.0, p = 0.0002), incision length (3.0 vs. 15.0, p < 0.0001), surgical wound classification (0 vs. 8.3%, p = 0.04), postoperative hospital stay (7.0 vs. 9.0, p = 0.0007), hospital expense (45.6 vs. 54.2, p = 0.0003), and postoperative complications (23.8% vs. 44.3%, p = 0.0040). Although patients in the ESC group experienced more surgical recurrence than those in the SSR group (8.3% vs. 3.2%) during the follow-up, the Kaplan-Meier curve analysis revealed no statistical difference (p = 0.29). CONCLUSIONS: The split stoma can be recommended when stoma construction is indicated in patients with Crohn's disease.
