Clinical analysis of laparoscopic and endoscopic cooperative surgery in the treatment of gastric gastrointestinal stromal tumor: report of 46 cases

Abstract

To evaluate the feasibility and safety of laparoscopic and endoscopic cooperative surgery for treating gastric gastrointestinal stromal tumors(GIST). Retrospective analysis was performed on the clinical data of 46 patients with gastric GIST undergoing laparoscopic and endoscopic cooperative surgery between June 2009 and June 2011 at the Renji Hospital of Shanghai Jiaotong University School of Medicine. There were 27 males and 19 females with the mean age of 58.5 years. Thirty-three patients received endoscopy-assisted wedge resection, and 13 cases received laparoscopy-assisted endoscopic resection. All the operations were successful. The mean operative time was (85.5±29.3) min, the mean blood loss was (31.4±12.2) ml, the mean post-operative gastrointestinal functional recovery time was (31.6±14.9) h, and the mean post-operative hospital stay was (5.1±2.9) d. No post-operative complication occurred. NIH risk assessment showed that 34 cases were very low risk and 12 low risk. No recurrence or metastasis was found during the follow-up ranging from 2 to 26 months(median, 12.6 months). Laparoscopic and endoscopic cooperative surgery for gastric GIST is both feasible and safe with minimal invasiveness, fast recovery and satisfactory short-term outcomes.
