Abstract
INTRODUCTION: Anastomotic leak and conduit necrosis are devastating complications following Ivor Lewis esophagectomy. Near infrared imaging (NIR) using IndoCyanine Green allows for real time tissue perfusion assessment which may reduce anastomotic leak during minimally invasive Ivor Lewis esophagectomy (MIE). METHODS: Forty consecutive MIE were performed by a single surgeon at a tertiary referral center. The first 20 were assessed for gastric conduit perfusion by clinical criteria (Group 1). The second 20 were also assessed using NIR laparoscopic system (Group 2). RESULTS: Comparing Group 1 to Group 2, no significant differences were found in overall complication rate, readmission or reoperation rate. NIR resulted in resection of the non perfused proximal portion of the conduit in 30% (6/20). Two patients in group 2 group developed anastomotic leak (2/20) compared to 0 in Group 1 (p = 0.49). Graft necrosis led to one mortality in Group 1, while there were 0 mortalities in Group 2. (p = 1.0). CONCLUSION: Although NIR plays a role in assessment of tissue perfusion, in our study its use did not result in reduction of anastomotic leak rate.
