Background. The optimal type of anastomosis after proximal gastrectomy (PG) is still controversial. A novel technique termed “double-flap” esophagogastrostomy (EG) has been introduced. The application of this technique after PG is reported to have little gastroesophageal reflux without the need of creating an esophagojejunostomy. However, this procedure is technically challenging and hence difficult to apply in laparoscopic PG. This technical report describes in detail how to perform single-incision proximal gastrectomy (SIPG) with double-flap EG with the use of novel laparoscopic instruments. Methods. Two patients diagnosed with early gastric cancer underwent SIPG. A 2.5 cm incision was made, and a scope holder was used in place of a scopist. After performing PG with D1+ lymphadenectomy, double seromuscular flaps were created on the anterior wall of the stomach. After tagging the esophagus to the inferior edge of the flap window, the stomach and esophagus were opened through electrocautery. EG was performed intracorporeally using continuous barbed sutures, and the flap is then secured to the anastomosis. To facilitate this procedure, an intra-abdominal organ retractor and an articulating needle holder were used. The supplementary video illustrates in detail how these devices are used to perform the technique. Results. Total operation times were 190 and 110 minutes each, and anastomosis took 75 and 46 minutes each. Patients had no complications and were both discharged on postoperative day 6. Conclusion. Double-flap PG is technically feasible through a single incision with the use of articulating laparoscopic devices and intra-abdominal organ retractors to assist in intracorporeal anastomosis.
