INTRODUCTION: Overlap guiding tube (OGT)-assisted overlap oesophagojejunostomy (EJS), which was first designed and reported by our team, has shown feasibility. However, its safety and efficiency have not yet been compared with the conventional overlap approach.
METHODS: We retrospectively analysed the data of 155 gastric/gastroesophageal junction (G/GEJ) cancer patients who underwent laparoscopic total gastrectomy by conventional (conventional group, n = 83) or OGT-assisted (OGT group, n = 72) overlap methods at Nanfang Hospital. The anastomotic efficiency and surgical outcomes were compared between the two groups.
RESULTS: The success rate of inserting an anvil fork into the oesophageal lumen at the first attempt in the OGT group was much higher than in the conventional group (86.7% vs. 97.2%, P = 0.019). Consistently, the duration of EJS (P < 0.001) in the OGT group was significantly shorter than that in the conventional group. Operatively, there was one case in which oesophageal pseudocanals developed; another case was converted to thoracoscopic surgery in the conventional group, but there were no such cases in the OGT group. In terms of postoperative recovery, the OGT group was superior to the conventional group. The incidence of postoperative complications (28.9% vs. 20.8%, P = 0.247) and the classification of complication severity (P = 0.450) were milder in the OGT group, although the difference was not statistically significant. Notably, the conventional group had four cases (4.8%) of oesophagojejunal anastomotic leakage (EJAL) and one case (1.2%) of anastomotic stenosis. In the OGT group, two patients (2.8%) developed EJAL, but none developed anastomotic stenosis or anastomotic bleeding. Neither group had any cases of unplanned secondary surgery or perioperative deaths.
CONCLUSIONS: The OGT-assisted method reduced the surgical difficulty of overlap EJS with good safety. This study provides new perspectives for optimizing EJS.
