Utility of single-port laparoscopic retrograde gastric mobilization during McKeown esophagectomy for esophageal cancer: a 2-year experience with 120 cases in a single institution.

Background: As a novel alternative to the conventional minimally invasive esophagectomy (MIE), more minimally invasive single-port laparoscopic retrograde 3-step gastric mobilization (SLRM) for esophageal reconstruction during MIE to treat esophageal cancer was attempted by our department. This study explored the preliminary clinical outcomes and feasibility of this innovative surgery. Methods: The data of 120 patients who had undergone SLRM combined with 4-port thoracoscopic McKeown esophagectomy for their esophageal cancers from March 2020 to November 2021 were reviewed. Gastric mobilization with abdominal lymph node dissection was performed via SLRM. The clinical characteristics and short-term outcomes were retrospectively analyzed. The data of operating time, blood loss, harvested lymph nodes, postoperative hospital stay and complications are presented as the mean and standard deviation. Results: A total of 120 patients underwent R0 resection without conversion to open surgery. The mean times for the thoracic procedure, abdominal procedure, and total operation were 43±6, 60±18, and 195±20 min, respectively. The numbers of mediastinal and abdominal lymph nodes harvested were 13.2±2.7, and 10.2±2.5, respectively. Postoperative pneumonia occurred in 10 patients (8.3%). Anastomotic leakage occurred in 3 patients (2.5%). Temporary vocal cord paralysis was reported in 20 patients (16.6%). The mean length of hospital stay was 8.5±4.6 days. Conclusions: SLRM is a technically feasible and safe treatment for patients with esophageal cancer. It can be considered an alternative method for patients, especially those with obesity and gastric distension.
