The purpose of this study was to review whether routine usage of indocyanine green (ICG) perfusion assessment during complex ileal J-pouch surgery requiring lengthening maneuvers reduces ischemic complications. Retrospective chart review of patients with ulcerative colitis (UC) or familial adenomatous polyposis (FAP) who underwent ileal pouch-anal anastomosis (IPAA) surgery with lengthening maneuvers and intraoperative ICG assessment between January 2015 and January 2021. All patients underwent a double stapled anastomosis and were temporarily diverted. All patients underwent laparoscopic and trans-anal ICG assessment of their J-pouch and anastomosis. All J-pouches were evaluated 6 weeks after surgery via contrast enema and pouchoscopy. One hundred fifty eight patients underwent ileal J-pouch surgery during the study period. Sixteen patients (10%) underwent lengthening maneuvers and intra-operative ICG assessment. Twelve patients underwent surgery for UC and 4 for FAP. Median age was 40.3 years and average body mass index was 24.9 kg/m2. Twelve patients underwent a two-stage procedure and the remaining underwent a three-stage procedure. 93.7% of cases were completed laparoscopically (15/16). All patients underwent scoring of the peritoneum and 43% (7/16) underwent division of the ileocolic or intermediate mesenteric vessels. There was no mortality or pouch ischemia and the leak rate was 12.5%. All patients underwent reversal after an average of 18 ± 7 weeks. ICG perfusion assessment appears to be of utility in complex IPAA surgery requiring lengthening maneuvers. Its application may be associated with reduced J-pouch ischemia and leak rate in this unique setting. © 2021. Springer Nature Switzerland AG.
