BACKGROUND This study aimed to establish an easy, safe, and cost-saving intestinal anastomotic method. MATERIAL AND METHODS Between January 2014 and February 2016, a total of 150 patients with gastric cancer who underwent surgery in the Department of General Surgery of Xuzhou Medical University Affiliated Hospital were divided into 2 groups: the treatment group (80) using new hand-sewn anastomoses, and the control group (70) using stapled anastomoses. Briefly, a new hand-sewn anastomosis of continuous suture without inversion was performed, with the first layer encompassing the entire layer of the intestinal wall. The edge was about 5 mm, and the stitch spacing was about 6 mm. Continuous suturing was performed only in the seromuscular layer of intestinal wall for the second layer, with the same edge and stitch spacing as the first layer. All 70 patients in the control group underwent intestinal stapled anastomoses. Surgical anastomotic time and cost, postoperative anastomotic bleeding, leakage, and stricture were recorded and analyzed. RESULTS The surgical anastomotic time using the new method was relatively short compared with the control group (8±1.6 min vs. 9±2.8 min), and the cost of anastomosis using the new method was significantly lower compared to the control group ($30±6.8 vs. $1000±106.2). The new method exhibited lower anastomotic bleeding (0/80 vs. 2/70) and anastomotic leakage (0/80 vs. 1/70), but similar anastomotic stricture (0/80 vs. 0/70). CONCLUSIONS Our results suggest the new hand-sewn intestinal anastomosis is a safe, easy-to-learn, cost-saving, and time-saving method that also avoids some of the drawbacks of the stapled anastomoses.

Possible mechanisms underlying diabetes remission following Roux-en-Y gastric bypass (RYGB) include eradication of putative factor(s) with duodenal-jejunal bypass. The objective of this study is to observe the effects of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass rat model. In order to verify the effect of duodenal-jejunal transit on glucose tolerance and diabetes remission in gastric bypass, 22 type 2 diabetes Sprague-Dawley rat models established through high-fat diet and low-dose streptozotocin (STZ) administered intraperitoneally were assigned to one of three groups: gastric bypass with duodenal-jejunal transit (GB-DJT n = 8), gastric bypass without duodenal-jejunal transit (RYGB n = 8), and sham (n = 6). Body weight, food intake, blood glucose, as well as meal-stimulated insulin, and incretin hormone responses were assessed to ascertain the effect of surgery in all groups. Oral glucose tolerance test (OGTT) and insulin tolerance test (ITT) were conducted three and 7 weeks after surgery. Comparing our GB-DJT to the RYGB group, we saw no differences in the mean decline in body weight, food intake, and blood glucose 8 weeks after surgery. GB-DJT group exhibited immediate and sustained glucose control throughout the study. Glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide (GIP) levels were also significantly increased from preoperative level in the GB-DJT group (p

Uterine rupture during pregnancy caused by uterine dysplasia, such as the double uterus, is very rare and easily overlooked by the surgeon. A 25-year-old woman, at 17 weeks of gestation presented to our emergency center with acute right lower abdominal pain for more than 10 h. The initial diagnosis is acute appendicitis, but during the exploration, we found about 2500 mL of intraperitoneal hemorrhage, appendix was normal, pregnancy in one of the double uterine and ruptured at the right bottom. The pregnancy was removed and the uterine defect was repaired. Uterine rupture caused by double uterus is very rare and easily Ignored by the surgeon. The survival of patients suffered from uterine rupture depends on the time interval between rupture and intervention.
