The use of circular stapler for cervical esophagogastric anastomosis after esophagectomy: surgical technique and early postoperative outcome

Stapled esophagogastric anastomosis after esophagectomy is considered to be superior to traditional handsewn techniques. Linear staplers are usually used. The aim of this study is to evaluate early postoperative results of circular stapler in cervical esophagogastric anastomosis. Records of all patients who underwent esophagectomy during the years 2003-2008 were reviewed. Patients that underwent transthoracic esophagectomy, colon transposition, or linear stapler anastomosis were excluded. Esophagogastric anastomosis was done either handsewn or using circular stapler. Patients underwent either pyloromyotomy, pyloroplasty, or no pyloric intervention. Postoperative leakage was diagnosed either clinically or radiologically. The end-point of this study was the incidence of anastomotic leak in the immediate postoperative period. Eighty-two patients (average age 66 years, male/female, 52/30) met the inclusion criteria. In 30 patients, the anastomosis was handsewn, and in 52 patients, it was done using a circular stapler. Overall operative mortality rate was 4.8% (four patients because of pulmonary or cardiac complications). Anastomotic leak occurred in five (n = 5, 16.6%) patients in the handsewn group and eight (n = 7, 13.4%) patients in the circular stapler group. Pyloric manipulation had no significant effect over the leakage rate. Routine upper-gastrointestinal (GI) series done on the fifth or sixth postoperative day did not reveal any of the leaks. Cervical esophagogastric anastomosis using an end-to-side circular stapler is feasible and safe, and has comparable outcomes to handsewn anastomosis in regard of leakage rates or other major surgical or general complications. Postoperative GI series seems to be a poor diagnostic tool for anastomotic leakage and could be omitted as a routine study for occult anastomotic leak.
