[Prone position thoracoscopic esophagectomy:preliminary experiences of thirty cases in Shanghai Chest Hospital]

Abstract

Objective: To examine the safety and short-term outcomes of prone position thoracoscopic esophagectomy. Methods: Clinical data of consecutive thirty patients who accepted prone position thoracoscopic esophagectomy at Department of Thoracic Surgery, Shanghai Chest Hospital between July and December 2020 was analyzed retrospectively. There were 25 males and 5 females, aging 65.5(29.0) years (M(Q_R))(range: 48 to 82 years). Patients with cT3-4a accounted for 73.3%(22/30) and cN(+) accounted for 43.4%(18/30). All the patients in this study had no serious comorbidity, accepted prone position thoracoscopic esophagectomy. Results: No conversion to thoracotomy occurred. The overall time of operation was 210 (105) minutes (range: 130 to 268 minutes), the time of thoracic procedures was 92 (46) minutes (range: 72 to 136 minutes), the time of abdominal procedures was 32 (14) minutes (range: 20 to 48 minutes), respectively. R0 resection accounted for 93.3%(28/30), the negative ratio of circumferential margin was 96.7%(29/30). The number of lymph nodes dissection was 21.5(7.2) (range: 16.0 to 28.0) in total, 12.0(6.5) (range: 9.0 to 18.0) in thoracic lymph nodes, 2.0(1.5) (range: 1.0 to 5.0) in left recurrent laryngeal nerve lymph nodes, and 1.0(1.0) (range: 1.0 to 3.0) in right recurrent laryngeal nerve lymph nodes, respectively. There was no perioperative death, and the overall postoperative complication rate was 43.3%(13/30). The incidence of anastomotic leakage was 10.0%(3/30), recurrent laryngeal nerve paralysis was 26.7%(8/30), and respiratory complication was 6.7%(2/30). The postoperative hospital stay was 10 (9) days (range: 5 to 42 days). Conclusion: Prone position thoracoscopic esophagectomy is safe and feasible, and the short-term outcomes is satisfactory.
