ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the feasibility of right neck anastomosis in thoracoscopic and laparoscopic esophagectomy.</p><p><b>METHODS</b>This study used a retrospective cohort study method. Clinical data of 169 patients with stage I-III esophageal squamous cell carcinoma undergoing neck anastomosis in thoracoscopic and laparoscopic esophagectomy at the Department 5 of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from November 2013 to October 2016 were retrospectively analyzed. Eighty-two cases underwent right neck anastomosis (right neck anastomosis group) and 87 cases underwent left neck anastomosis(left neck anastomosis group). Both groups underwent routine thoracoscopic and laparoscopic radical resection of esophageal cancer. The entry of right and left neck anastomosis group was at the anterior edge of the right and left sternocleidomastoid muscle respectively. Anastomosis of the esophagogastric junction was performed and the drainage tube was placed in the neck incision. The operation time, intraoperative blood loss, lymph node dissection and morbidity of postoperative complications were compared between the two groups.</p><p><b>RESULTS</b>There were 101 males and 68 females among 169 patients with esophageal cancer. There were no significant differences in age, gender, tumor location, clinical stage between two groups(all P>0.05). The total operation time of left and right neck anastomosis groups was (278.3±39.4) minutes and (287.8±39.4) minutes, respectively (t=1.563, P=0.120). The intraoperative blood loss was (134.9±71.5) ml and(147.9±85.5) ml, respectively (t=1.074, P=0.284). The number of lymph node dissections was (17.45±5.68) and (16.47±4.98), respectively (t=1.190, P=0.236). Seventeen cases(20.7%) in the right neck anastomosis group developed postoperative complications, while 31 cases (35.6%) in the left neck anastomosis group developed postoperative complications (χ²=4.609,P=0.032). Compared with left neck anastomosis group, right neck anastomosis group had lower rate of gastric emptying disorder (0% vs. 6.9%, P=0.029), anastomotic fistula (7.3% vs. 18.4%, χ²=4.572, P=0.033), pneumonia (18.3% vs. 32.2%, χ²=4.294, P=0.038) and ICU management (4.9% vs. 16.1%, χ²=4.726, P=0.030).</p><p><b>CONCLUSION</b>Thoracoscopic and laparoscopic esophagectomy with right neck anastomosis is safe and effective, can completely remove the tumor, at the same time, has less complications than left neck anastomosis, and improve the quality of life.</p>
