Background
Controversies in terms of efficacy and postoperative advantages surround stapled esophagogastric anastomosis compared with the hand-sewn technique as a treatment for patients with esophageal cancer. The purpose of this study was to compare the clinical outcomes of hand-sewn end-to-side esophago-gastrostomy and side-to-side stapled cervical esophagogastric anastomosis after esophagectomy for the aforementioned patients.
Methods
This retrospective cohort study involved examining the medical records of 433 patients who underwent transhiatal esophagectomy for esophageal cancer from March 2010 to March 2016. All the patients were operated using end-to-side hand-sewn esophago-gastrostomy and side-to-side stapled cervical esophagogastric anastomosis. 409 of the patients received a year’s worth of follow-up evaluations. All the cases were revisited in 2 weeks as well as in four, eight, and 12 months after surgery. The patients were assessed in terms of postoperative outcomes, including reflux symptoms, anastomotic leakage and stricture, and the need for anastomotic dilatation.
Results
Hand-sewn anastomosis was carried out in 271 (62.5%) patients, whereas stapled anastomosis was performed in 162 (37.4%) patients. The mean operative times were 214.46 ± 84.33 min and 250.55 ± 43.31 min for the stapled and hand-sewn anastomosis groups, respectively (P = 0.028). The two groups showed no significant differences with respect to stays in intensive care units and hospitals. Postoperatively, 38 (14.67%) cases of anastomotic leakage were detected in the hand-sewn anastomosis group, with incidence being significantly higher than that in the stapled anastomosis group (8 cases or 5.33%; P = 0.002). Anastomotic stricture occurred less frequently in the patients who underwent stapled anastomosis (P = 0.004). Within the one-year follow-up period, the patients treated via hand-sewn anastomosis more frequently required anastomotic dilatation (P = 0.02).
Conclusion
Side-to-side stapled cervical esophagogastric anastomosis may reduce operation times and decrease the rates of anastomotic leakage, anastomotic stricture, and anastomotic dilatation in patients with lower thoracic esophageal cancer undergoing transhiatal esophagectomy.
