Abstract:Abstract: Objective To investigate the safety and efficacy of unidirectional barbed suture in annular pancreas children of laparoscopic duodena-jejunal bypass of duodenum. Methods 21 children with annular pancreas underwent laparoscopic duodena-jejunal bypass of duodenum from January 2016 to April 2018 and were prospectively analyzed. According to the random number table method, children patients were randomly divided into unidirectional barbed suture group (n = 8) for laparoscopic duodena-jejunal bypass of duodenum and normal absorbable suture group for laparoscopic duodena-jejunal bypass of duodenum (n = 13). Compare with the differences of the two suture methods in operation time, incidence of intestinal leakage (intraoperative and postoperative), weight of postoperative drainage, weight of gastrointestinal decompression drainage fluid. Results All the children were successfully operated without conversion to open surgery, and the time of duodena-jejunal bypass suture closure in unidirectional barbed suture group was less than that in normal absorbable suture group [(15.13 ± 1.96) min vs (17.46 ± 1.61) min, t = -2.97, P < 0.05]. The weight of postoperative drainage of duodena-jejunal bypass suture closure in unidirectional barbed suture group was also less than that in normal absorbable suture group [(19.94 ± 6.67) g vs (22.25 ± 6.94) g, t = -2.31, P < 0.05] The incidence of intestinal leakage (intraoperative and postoperative) and the weight of gastrointestinal decompression drainage fluid between the two groups were not statistically significant (P > 0.05). Conclusions Compare of normal absorbable suture, unidirectional barbed suture is short of suture time and less drainage after operation in laparoscopic duodena-jejunal bypass of duodenum, so it is worth popularizing in clinic.
