Surgical Outcomes of Single-Port and Multiport Laparoscopic Resection for Gastric Gastrointestinal Stromal Tumors (GIST): a Single-Center Experience

Although single-port laparoscopic resection of gastrointestinal stromal tumor (GIST) offers advantages over multiport procedures in terms of reduced pain, faster recovery, and superior cosmetic results, its efficacy and indications are not fully established. In this study, we compared the safety and efficacy of single-port and multiport laparoscopic resection for GIST. We evaluated 85 consecutive patients (age > 18 years) with GISTs who underwent gastric wedge resection at an area hospital between January 2000 and December 2014. The surgical outcomes of patients undergoing single-port (S group) and multiport (M group) laparoscopic resections were compared. There were 61 patients in the M group and 24 in the S group. No statistically significant differences in patient characteristics (sex ratio, age, performance status, physical status), surgical factors (operative time, blood loss), postoperative course (time to resumption of oral intake, length of hospital stay), or treatment outcome (receipt of adjuvant therapy, tumor recurrence) were found between the M and S groups (all p > 0.05). Patients in the M group had larger tumors than those in the S group (mean 36.6 ± 14.8 mm vs. 26.4 ± 7.9 mm; p < 0.05) and their tumors were more likely to demonstrate extramural growth (56 vs. 66.7%; p < 0.05). Our results show that both single-port and multiport laparoscopic resection for GIST are safe and effective.
