Effect of Double-Channel Anastomosis and Esophagojejunal Anastomosis on Postoperative Recovery and Complications of Laparoscopic D2 Radical Gastrectomy for Gastric Cancer

The aim of this study was to investigate the effects of double-channel anastomosis versus esophagojejunostomy on postoperative recovery and complications after laparoscopic D2 radical gastrectomy for early proximal gastric cancer. The cases were collected from 100 patients with early proximal gastric cancer admitted to our hospital from January 2017 to January 2021. According to different surgical methods, they were divided into control group (total gastrectomy + esophagojejunal anastomosis) and experimental group (D2 radical resection + double-channel anastomosis). The two groups were compared in terms of clinical outcomes (operative time, intraoperative blood loss, number of lymph nodes dissected, digestive tract anastomosis time, postoperative exhaust, and hospitalization days), postoperative complications, and nutritional status; the expression of T lymphocyte subsets in peripheral blood of the two groups was detected to reflect the recovery of immune ability. There was no significant difference between the observation group and the control group in clinical operation effect indexes (P < 0.05). The incidence of complications of dumping syndrome and reflux esophagitis in the observation group was significantly lower than that in the control group (P < 0.05). In terms of postoperative nutritional status, the ratio of plasma albumin level and body weight restored to operation at 12 and 24 weeks after operation in the observation group was significantly higher than that in the control group (P < 0.05). 3 months after the operation, the levels of CD3 +, CD4 + cell subsets, and CD4+/CD8+ index reflecting the recovery of immune ability in the observation group were significantly higher than those in the observation group (P < 0.05). The application of double-channel anastomosis in laparoscopic D2 radical gastrectomy for early proximal gastric cancer has a better effect on reducing complications and promoting postoperative recovery, which is of great application value.
