[Application of laminated anastomosis with absorbable suture in cervical esophagogastrostomy].

OBJECTIVE

To observe the clinical results of laminated anastomosis using absorbable suture in cervical esophagogastrostomy, and to reduce the incidence of cervical esophagogastric anastomotic stricture.

METHODS

A retrospective analysis was carried out on 210 patients who underwent cervical esophagogastrostomy after subtotal esophagectomy from January 2008 to June 2010. Among them, 96 cases were treated with traditional full layer interrupted varus suture (varus group) and the remaining 114 cases were treated with seromuscular layer and mucosal layer laminated anastomosis with absorbable suture (laminated group). Esophageal angiography was performed in 1 week, 1 month, and 3 months after the operation. The diameter of anastomatic stoma was measured on the anteroposterior and lateral angiography image respectively. The area of anastomatic stoma was calculated. The degree of stenosis was assessed according to the patients' dysphagia symptom.

RESULTS

There was no operative deaths, no serious pulmonary complications and chylothorax, no sever esophageal reflux in all patients. The ratio of cervical esophagogastric anastomotic leakage was 2.1% (2/96) in the varus group. No anastomotic leakage in the laminated group. Compared with the varus group, the area of the anastomatic stoma in the laminated group was significantly increased in all measured time points (P<0.01). The incidence of obstruction in the laminated group was decreased significantly (P<0.01) in 1 month or in 3 months after operation compared with the varus group.

CONCLUSION

Application of the laminated anastomosis with absorbable suture in cervical esophagogastrostomy can significantly reduce the incidence of anastomotic stenosis.
