Abstract
BACKGROUND: Colonic anastomotic leaks are associated with significant morbidity and mortality. Whereas small case series suggest that fully covered self-expandable metal stents (FCSEMS) are effective, no larger studies have examined the impact of combination endoscopic therapy on colonic anastomotic leaks. METHODS: Our retrospective cohort study reviewed 51 patients undergoing endoscopic therapy for colonic anastomotic leaks between 2011 and 2018. Patients receiving combination therapy involving FCSEMS plus local closure (n = 24) were compared with patients receiving FCSEMS alone (n = 18) or endoscopic suturing alone (n = 9). The primary outcomes were technical and clinical success (resolution of leak, removal of percutaneous drains, avoidance of surgical reoperation, and reversal of temporary diversion). RESULTS: Clinical success was achieved in 55 % of patients. Clinical success was achieved in 18/24 patients (75 %) with combination therapy compared with 6/18 patients receiving FCSEMS alone (33 %, adjusted risk ratio [RR] 2.16, 95 % confidence interval [CI] 1.10 - 4.24; P = 0.02) and 4 /9 patients undergoing endoscopic suturing alone (44 %, RR 1.91, 95 %CI 0.84 - 4.31; P = 0.10). Stent migration occurred in 40 % of patients. CONCLUSIONS: This large series demonstrates that combination therapy was associated with a higher rate of clinical success, and future prospective studies are warranted. Thieme. All rights reserved.
