Robotic Proximal Gastrectomy with Double-Tract Reconstruction for Gastroesophageal Junction Cancer

AbstractThe current standard surgical procedure for proximal gastric and gastroesophageal junction (P/GEJ) cancers with limited esophageal involvement is total gastrectomy (TG). TG is associated with impaired appetite and weight loss due to decreased levels of ghrelin (a “hunger hormone” secreted by the stomach) and with anemia due to intrinsic factor loss and vitamin B12 malabsorption. Theoretically, proximal gastrectomy (PG) with an anti-reflux technique such as double-tract reconstruction (DTR) can improve quality of life (QoL) by preserving gastric function.1 A recent Japanese prospective GEJ adenocarcinoma study reported a low incidence of lymph node metastases at peripyloric stations,2 indicating the oncological safety of PG for GEJ adenocarcinoma regardless of tumor stage. As a result, PG is increasingly performed in South Korea and Japan, although the QoL benefit of PG over TG remains unknown.3,4 We have performed PG with DTR in select cases with satisfying short-term outcomes. In this video, we introduce our technique for robotic PG with DTR. The presented case is a 75-year-old woman with GEJ adenocarcinoma that showed an excellent response to preoperative chemoradiation therapy. The patient underwent robotic PG with DTR. Fluorescent sentinel lymphatic mapping was performed by injecting indocyanine green solution (total of 2 ml, at four quadrants around the tumor at submucosal space) via endoscopy at the beginning of the operation. It showed absence of sentinel l...
