Clinical application and observation of modified Ivor-Lewis surgery in Siewert type II adenocarcinoma of the Esophagogastric junction

Abstract

Abstract Background The surgical approach (transthoracic or transabdominal) for patients with Siewert type II adenocarcinoma of the esophagogastric junction (AEG) still remains controversial. We made a bold attempt to adopt the modified Ivor-Lewis surgery, No turning over, thoraco-laparoscopic esophagogastrectomy, two-field lymphadenectomy and intrathoracic anastomosis, to observe the clinical application and effect. Method Data of patients with Siewert type II AEG were collected in the Hebei General Hospital from June 2017 to February 2019. The operation time, surgical blood loss, the number of dissected lymph nodes, duration of drainage tube, postoperative complications, the length of postoperative hospital stay were collected to assess the safety and feasibility of modified Ivor-Lewis surgery. Results A total of 20 patients with Siewert type II AEG were analyzed in our research, there was no case of turning to thoracotomy, laparotomy or death during the operation.The average operation time, surgical blood loss, amount of dissected lymph nodes, duration of drainage tube, postoperative hospital stay of all enrolled patients was 4.67, 0.57 h, 156, 56.80 ml, 22.55, 3.91, 8.6, 2.21 days, 12.85, 2.5 days respectively. Among all the enrolled patients, one patient(5%) developed anastomotic fistula and one patient(5%) developed hematemesis after operation, eventually, these two patients were discharged successfully. Conclusion For patients with Siewert type II AEG, The modified Ivor-Lewis surgery, No turning over, thoraco-laparoscopic esophagogastrectomy, two-field lymphadenectomy and intrathoracic anastomosis, is safe and feasible. The feasibility and safety could be further and better investigated with a RCT to achieve more conclusive results.
