Laparoscopic"Making-dumplings"Resection of Gastrointestinal Stromal Tumor: Report of 50 Cases / 中国微创外科杂志

ABSTRACT

Objective To explore the clinical effect and feasibility of laparoscopic "making-dumplings"resection for gastrointestinal stromal tumor (GIST). Methods Fifty patients with GIST underwent laparoscopic "making-dumplings"resection from July 2010 to February 2015.We used suture to overhang the tumor , then sealed the lesion with linear cutting stapler like "making-dumplings", finally resected it with a more than 2 cm edge. Results The operation time was (95.8 ±34.2) min and the intraoperative blood loss was (40.2 ±17.9) ml.The tumor body of resected specimen was intact , and the resection margin was more than 2 cm.GIST was diagnosed by pathological examination and immunohistological staining .There were 5 cases of tumor diameter >5 cm, 23 cases between 2 cm and 5 cm, and 22 cases less than 2 cm.No residual tumor or lymph node metastasis was found . According to newly revised NIH risk grading standards , there were 20 cases of very low risk , 17 cases of low risk , 7 cases of moderate risk, and 6 cases of high risk.The mean follow-up time after operation was 24 months (range, 8-36 months).There was one case of omentum metastasis after 3 months operation which was reoperated , and the remaining 49 cases had no recurrence or metastasis under gastroscopy , ultrasonography and CT scanning . Conclusion Laparoscopic "making-dumplings"resection for GIST is feasible and effective, being worthy of further clinical application .
