Despite decreasing overall morbidity with minimally invasive esophagectomy (MIE), conduit functional outcomes related to delayed emptying remain challenging, especially in the immediate postoperative setting. Yet, this problem has not been described well in the literature. Utilizing a single institutional prospective database, 254 patients who underwent MIEs between 2012 and 2020 were identified. Gastric conduit dilation was defined as a conduit occupying >40% of the hemithorax on the postoperative chest X-ray. Sixty-seven patients (26.4%) demonstrated acute conduit dilation. There was a higher incidence of conduit dilation in the patients who underwent Ivor Lewis esophagectomy compared to those with a neck anastomosis (67.2% vs. 47.1%; P = 0.03). Patients with dilated conduits required more esophagogastroduodenoscopies (EGD) (P < 0.001), conduit-related reoperations within 180 days (P < 0.001), and 90-day readmissions (P = 0.01). Furthermore, in 37 patients (25.5%) undergoing Ivor Lewis esophagectomy, we returned to the abdomen after intrathoracic anastomosis to reduce redundant conduit and pexy the conduit to the crura. While conduit dilation rates were similar, those who had intraabdominal gastropexy required EGD significantly less and trended toward a lower incidence of conduit-related reoperations (5.6% vs. 2.7%). Multivariable analysis also demonstrated that conduit dilation was an independent predictor for delayed gastric conduit emptying symptoms, EGD within 90 days, conduit-related reoperation within 180 days, and 30-day as well as 90-day readmission. Patients undergoing MIE with acute gastric conduit dilation require more endoscopic interventions and reoperations.
