Hand-sewn esophagojejunostomy in transthoracic single-port assisted laparoscopic esophagogastrectomy for Siewert type II adenocarcinoma of the esophagogastric junction with esophageal invasion > 3 cm

Background An optimal method for digestive tract reconstruction (DTR) in laparoscopic radical resection of Siewert type II adenocarcinoma of esophagogastric junction (AEG) has not yet been standardized. The aim of this study was to evaluate the safety and feasibility of a hand-sewn esophagojejunostomy (EJ) technique during transthoracic single-port assisted laparoscopic esophagogastrectomy (TSLE) for Siewert type II AEG with esophageal invasion > 3 cm. Methods The perioperative clinical data and short-term outcomes for patients who underwent TSLE using hand-sewn EJ for Siewert type II AEG with esophageal invasion > 3 cm between March 2019 and April 2022 have been retrospectively reviewed. Results A total of 25 patients were eligible. All 25 patients were successfully operated. None was converted to open surgery or mortality. 84.00% of patients were male and 16.00% were female. The mean age, body mass index (BMI), and the American Society of Anesthesiologists (ASA) score were 67.88 ± 8.10 years, 21.30 ± 2.80 kg/m 2 , and 2.08, respectively. The average incorporated operative and hand-sewn EJ procedural times were 274.92 ± 57.46 and 23.36 ± 3.00 min, respectively. The length of extracorporeal esophageal involvement and proximal margin was 3.31 ± 0.26 cm and 3.12 ± 0.12 cm, respectively. The average time for the first oral feeding and hospital stay were 6 (3–14) and 7 (3–18) days, respectively. Two patients (8.00%) developed postoperative grade IIIa complications according to the Clavien–Dindo classification, including 1 case of pleural effusion and 1 case of anastomotic leakage, both of whom were cured by puncture drainage. Conclusion Hand-sewn EJ in TSLE is safe and feasible for Siewert type II AEG. This method can ensure safe proximal margins and could be a good option with an advanced endoscopic suture technique for type II tumor with esophageal invasion > 3 cm.
