Comparison of the outcomes between thoracoscopic and laparoscopic esophagectomy via retrosternal and prevertebral lifting paths by the same surgeon

BACKGROUND: The objective of the study is to explore the effects of retrosternal and prevertebral lifting paths of the tubular stomach on postoperative complications of patients undergoing cervical anastomosis in thoracoscopic and laparoscopic esophagectomy. METHODS: Sixty-three patients were retrospectively analyzed. The patients received thoracoscopic and laparoscopic esophagectomy by the same surgeon. According to the path by which the stomach was lifted upward, the patients were divided into two groups: the retrosternal path group (32 patients) and the prevertebral path group (31 patients). Operative indications and complications of postoperative patients in these two groups were observed. RESULTS: There was no statistically significant difference in the time duration of surgery, amount of bleeding, number of dissected lymph node, and postoperative hospitalization time between the retrosternal and prevertebral lifting paths (P > 0.05). Furthermore, the two groups did not show significant difference in the incidence rate of postoperative anastomosis fistula complications (P = 0.702). Instead, the amount of postoperative gastric drainage and the incidence rates of the pulmonary infection were significantly lower in the retrosternal path group than in the prevertebral path group, respectively (P = 0.001, P = 0.012, respectively). CONCLUSION: The esophagogastrostomic cervical anastomoses performed via the retrosternal and prevertebral paths are both feasible methods of digestive tract reconstruction. The amount of postoperative gastric drainage volume and the pulmonary infection incidence rate in the retrosternal path group were lower than those in the prevertebral path group. Therefore, gastroesophageal anastomosis via the retrosternal lifting path may be preferably considered for thoracoscopic and laparoscopic surgery for esophageal carcinoma patients.
