Abstract: Objective To investigate the effect and feasibility of ropivacaine in local postoperative abdominal incisional pain in patients with minimally invasive esophageal cancer.Methods A retrospective analysis of 134 patients with thoracic esophageal cancer treated by thoracic and laparoscopic radical treatment at the Cardiothoracic Surgery from March 2017 to September 2018.Patients were divided into two groups.Group A（66 cases） were patients who didn’t have disposable venous infusion needle left in the abdominal incision during the surgery and didn’t take ropivacaine after the surgery while group B（68 cases）  were patients who had indwelled disposable intravenous infusion needle at the abdominal incision during the surgery and have taken ropivacaineafter the surgery.Abdominal median incision pain score，postoperative fat liquefaction，infection and other related complicationsof the two groups were compared after the surgery.Results Compared with group A patients，the median abdominal incision pain score（VAS）was lower in the group B in the first three days after the surgery,which was（4.1±0.9）VS（3.1±0.8）,（4.0±0.9）VS（2.9±0.9）,（3.7±0.8）VS（2.7±0.8）,respectively，and the difference was statistically significant（P<0.05）.Patients who had taken additional analgesic drugs（tramadol）were few[36.36%（24/66）VS 11.76（8/68） ,P＜0.05].There was no significant difference in fat liquefaction and infection between median abdominal incisions（P>0.05）.No cases of abdominal infection were found in both groups.Conclusion Ropivacaine for localized minimally invasive esophageal carcinoma is effective for the postoperative abdominal incision analgesia；meanwhile it does not increase the incidence of fat liquefaction，infection and abdominal infection in the middle abdominal incision，which is ideal method for minimally invasive esophageal cancer.
