Comparison of incidence rate of anastomotic stricture between conventional anastomosis and double-layers anastomosis after operation of esophageal cancer / 中华老年医学杂志

ABSTRACT

Objective To explore how to decrease the incidence of anastomotic stricture after the operation of esophageal cancer by improving anastomosis.Methods Clinical data of 374 cases aged ＞ 60 years who had undergone left thoracotomy radical resection of esophagus cancer at our hospital from April 2013 to August 2015 were collected.Patients were divided into double-layers anastomosis group (n=187) and conventional anastomosis group (n=187).During process of stapling anastomosis,double purse string anastomosis on esophagus and gastric wall were performed in doublelayers anastomosis group,with no purse string suture in conventional anastomosis group.Incidence rate of anastomotic stricture was compared between the two groups.Results Conventional anastomosis group versus double-layers anastomosis group showed that a mild anastomotic stricture occurred in 17 cases (9.1 ％) versus 7 cases (3.7 ％) (x2 =4.452,P =0.035),a moderate anastomotic stricture in 12 cases(6.4 ％) vs.4 cases (2.1 ％) (x2 =4.179,P =0.041),a severe anastomotic stricture in 9 cases (4.8％)vs.3 cases(1.6％)(x2 =3.099,P=0.078),total number of anastomotic stricture in 38 cases vs.14 cases (x2 =12.866,P =0.000),showing that double-layers anastomosis was relatively superior to conventional anastomosis.Conclusions Double-layers anastomosis can effectively reduce the incidence of anastomotic stricture after surgery.
