Abstract
Objective
During totally minimally invasive esophagectomy (MIE), the gastric conduit is typically constructed via laparoscopy. Trauma from laparoscopic instruments, inability to palpate the gastroepiploic arcade, and challenges in optimal positioning of the stomach for intra-abdominal stapling have led to the widespread use of laparotomy as part of hybrid MIE procedures. Our objective was to evaluate the safety of transthoracic extracorporeal gastric conduit preparation. We hypothesize that this alternative technique is equivalent in safety to the laparoscopic approach.
Methods
This is a retrospective comparison of laparoscopic and transthoracic extracorporeal gastric conduit preparation with regard to anastomotic and respiratory outcomes.
Results
During a 3-year period, 30 patients underwent MIE with a right intrathoracic anastomosis (extracorporeal conduit, 15; laparoscopic conduit, 15). Mean age (58.6 vs 67 years, P = 0.59), tumor location (gastroesophageal junction vs middle and lower esophageal, P = 0.27), and histology (adenocarcinoma vs other 26.7%, P = 0.68) were similar between groups. Anastomotic technique and operating surgeon were the same for all patients. Patients in the laparoscopic gastric conduit group were more likely to have undergone induction chemoradiotherapy (40% vs 80%, P = 0.030). There was no significant difference between groups with respect to anastomotic complications, including anastomotic leak and anastomotic stricture (20% vs 13.3%, P = 0.70). Transthoracic gastric conduit preparation was not associated with increased respiratory complications (8% vs 12%, P = 0.09).
Conclusions
Transthoracic gastric conduit preparation is a simple, minimally invasive alternative laparotomy for gastric conduit preparation during MIE. No additional incision is required. The technique may help surgeons overcome shortcomings of the laparoscopic approach without impacting perioperative risk.
