Laparoscopic surgery for rectal stromal tumor: a report of 16 cases / 第二军医大学学报

ABSTRACT

Objective To explore the feasibility and safety of laparoscopic resection for rectal stromal tumor.Methods Sixteen (10 male and 6 female) patients underwent laparascopic resection of rectal stromal tumor in our department from May 2013 to Dec.2016,and the tumor diameter of all patients was less than 5 cm.The patients with the distance of more than 5 cm from the lower margin of the tumor to the anal verge received laparoscopic anterior resection of the rectal carcinoma (Dixon),the patients with the distance of less than 5 cm and more than 3 cm received laparoscopic local resection,and the patients with the distance of less than 3 cm,whose tumor boundary with the surrounding tissue were unclear,received laparoscopic abdominal perineal resection (Miles).Results The rectal stromal tumors of 16 cases were successfully removed under laparoscope without conversion to laparotomy,and no post-operative complications such as perforation,bleeding,obstruction or anastomotic leakage occurred.Of 16 cases,12 underwent laparoscopic anterior resection of the rectal carcinoma (Dixon),3 underwent laparoscopie local resection,and 1 underwent laparoscopic perineal resection (Miles).The average operation time was (103.0±23.8) min,the average hospital stay was (7.0 ± 1.2) days,and the average volume of intra-operative bleeding was (14 ± 4.1) mL.The pathological findings were confirmed as stromal tumor with negative margin.There was no recurrence during the followup of 8 to 40 months.Two cases with the tumor transferring to the liver eventually died of liver metastasis.Conclusion Laparoscopic resection of rectal stromal tumors is safe and feasible,with less trauma,shorter hospitalization time and quicker post-operative recovery.
