Intrathoracic hand-sewn esophagogastric anastomosis in prone position during totally minimally invasive two-stage esophagectomy for esophageal cancer.

Utilization of totally minimally invasive esophagectomy for cancer is on the rise. Esophagogastric anastomosis is mechanically or robotically performed routinely; little report exists of hand-sewn esophagogastric anastomosis. This is the largest so far study with thoracoscopic hand-sewn esophagogastric anastomosis during fully minimally invasive two-stage esophagectomy for esophageal cancer in prone position. Consecutive two-stage totally minimally invasive esophagectomies for cancer were performed by one surgical team, from September 2016 to March 2019. All operations were technically identical in terms of patient positioning, surgical approach, extend of lymphadenectomy and type of anastomosis formed. Primary end points were anastomotic leak and anastomotic stricture rate, while secondary end points were 30-day and 90-day mortality rates. From the overall n = 80 patients, n = 67 were males, while n = 13 were females. Mean age was 64.6 years. Mean length of stay was n = 14 days. There were no conversions to open. Mean operating time was 420 minutes with no blood loss over 200 mL noted. Pulmonary and cardiac complication rate was 23.75% and 2.5%, respectively. Anastomotic leak rate was 2.5%. Anastomotic strictures were seen in 12.5% of cases. 30-day and 90-day mortality rate was 2.5% and 5%, respectively, with none accounted for ischemic conduit complications. Intrathoracic anastomosis in totally minimally invasive esophagectomy is challenging and accountable for most of the mortality associated with the procedure. In thoracoscopic two-stage esophagectomy, a mechanical anastomosis is usually preferred; this is believed to be due to the complexity of manual anastomosis associated with the thoracoscopic approach. We aim to present our series of completely hand-sewn intrathoracic anastomosis utilizing a totally minimally invasive approach with favorable outcomes. With this study, reproducibility of the anastomosis is shown that can potentially favor a change in the practice of esophageal surgeons worldwide.
