Effect observation of uncut Roux-en-Y anastomosis in laparoscopic assisted radical gastrectomy for distal gastric cancer / 中国综合临床

ABSTRACT

Objective:To investigate the effect of uncut Roux-en-Y anastomosis in laparoscopic assisted radical gastrectomy for distal gastric cancer.Methods:The clinical data of 53 patients with distal gastric cancer treated by surgery in Tangshan Union Medical College Hospital from May 2016 to October 2019 were analyzed retrospectively.The operation method was laparoscopic assisted radical gastrectomy for distal gastric cancer.The anastomosis methods were uncut Roux-en-Y anastomosis in 29 cases (uncut group) and Roux-en-Y anastomosis in 24 cases (traditional group). The operation time, digestive tract reconstruction time, the time to flatus, length of hospital stay, incidence of complication and one year followed up results were compared between the two groups.Results:The operation time was (196.0±28.8) min, anastomotic time was (56.1±13.8) min, postoperative exhaust time was (52.5±14.4) h, postoperative hospital stay was (12.5±2.8) d in the uncut group, and (201.0±28.5) min, (57.8±12.9) min, (53.9±14.6) h, (12.0±3.0) d in the traditional group.There was no significant difference between the two groups ( P values were 0.534, 0.664, 0.717 and 0.557, respectively). Postoperative complications anastomotic leakage was 0(0/29), abdominal bleeding was 3.4% (1/29), alkaline reflux gastritis was 6.9% (2/29) in the uncut group and 4.2% (1/24), 4.2% (1/24) and 4.2% (1/24) in the traditional group respectively.There was no significant difference between the two groups ( P values were 0.453, 1.000 and 1.000, respectively). The incidence of Roux-en-Y stasis syndrome was 0 (0/29) in the uncut group and 25.0% (6/24) in the traditional group.There was significant difference between the two groups ( P=0.006). One case in the uncut group was found recanalization 8 months after operation, the patient underwent reoperation, the method of anastomosis was changed to traditional Roux-en-Y anastomosis.The patient′s symptoms of reflux and hearburn improved significantly after operation. Conclusion:As a digestive tract reconstruction method for radical gastrectomy of distal gastric cancer, uncut Roux-en-Y anastomosis is safe and feasible, and can avoid Roux-en-Y stasis syndrome.
