| Summary: | Abstract Objective To evaluate the intraoperative and short-term postoperative outcomes of a novel robotic intracorporeal π-shaped esophagojejunostomy (EJS) after D2 total gastrectomy (TG) using the Da Vinci robotic surgical system for intracorporeal anastomosis after TG. Background Intracorporeal π-shaped EJS, using a linear stapler, was recently reported for laparoscopic total gastrectomy in patients with gastric cancer. However, robotic intracorporeal π-shaped EJS using a linear stapler has not been reported. This report aimed to describe the use of a novel technique for π-shaped EJS using the Da Vinci robotic system. Methods Robotic intracorporeal π-shaped esophagojejunostomy after total gastrectomy was performed in 11 consecutive patients diagnosed with early gastric cancer, and their perioperative outcomes were analyzed. Results All the operations were successful without conversion to open or laparoscopic surgery and postoperative complications. The total number of patients was 11 (7 males and 4 females). The mean age of the patients was 63.36 ± 10.56 years old. Seven patients were diagnosed with cardia cancer, 3 patients were diagnosed with gastric body cancer, and 1 patient was diagnosed with gastric antrum cancer. The patients’ mean proximal resection margin was 3.18 ± 1.17 cm, the distal resection margin was 6.18 ± 1.40 cm, the mean length of the incision was 4.55 ± 0.69 cm, the mean operative time was 287.27 ± 30.69 min, the mean day of first flatus was 3.27 ± 0.79 days, the mean day of the start of diet was 2.91 ± 0.94 days, the mean postoperative hospital stay was 11.45 ± 5.13 days, and the mean operative blood loss was 47.27 ± 31.33 ml. No complications were observed during anastomosis, and the median anastomosis time was 19.5 min. The mean number of lymph node dissections was 17.91 ± 4.59, the mean number of positive lymph nodes was 0.45 ± 0.69, all patients were diagnosed with stage I–II gastric cancer, and the mean maximum diameter of the tumor was 2.67 ± 1.30 cm. All the patients had a smooth hospital discharge. Conclusion A novel robotic gastrectomy with intracorporeal π-shaped EJS for esophagojejunal anastomosis described and shows acceptable resulted. This technique has the potential to offer better short-term surgical outcomes and overcomes the drawbacks of laparoscopy with a decreased risk of complications during and after surgery.
