Laparoscopic resection for gastric stromal tumors with sizes larger than 5 cm / 中华普通外科杂志

ABSTRACT

Objective To investigate the treatment efficacy,feasibility and safety of laparoscopic resection for gastric gastrointestinal stromal tumors (GISTs) larger than 5 cm.Methods The clinical data of 31 patients who underwent laparoscopic resection of large gastric GISTs between Jan 2010 and Jun 2017 at Sir Run Run Shaw Hospital and People's Hospital of Zhejiang Province were retrospectively analyzed.Results All operations were successful.Two patients were converted to open surgery.The mean tumor size was (7.2 ±0.5) cm.The mean operation time was (127 ± 12) min,intraoperative blood loss was (83 ±25) ml.The first flatus time was (2.2 ±0.8) days,the first diet resumption time was (2.4 ± 1.2) days,and the median postoperative hospital stay was (5.5 ± 1.5) days.The median follow-up time was 25 months.One patient developing liver metastasis 41 months after primary resection received oral mesylate imatinib therapy for 24 months and was still alive at the last follow-up.One patient died of lung cancer 33 months after primary operation without recurrence of gastric GIST.Conclusions Laparoscopic surgery for gastric GIST larger than 5 cm on laparoscopicaly accessible location is feasible and safe.
