Abstract
BackgroundAlthough the feasibility of minimally invasive resection of small gastric GISTs is well established, less is known about safety and efficacy of laparoscopic surgery for large tumors. MethodsA retrospective analysis was performed, using a prospectively maintained comprehensive database. Patients were divided into two groups according to tumor size: Case group with tumors > 5 cm and control group with tumors <5 cm. Hospital charts were reviewed, and various outcome measures recorded, including operative time, estimated operative blood loss, post-operative leak, stasis, infection and recurrence. ResultsNo tumors were ruptured during surgical manipulation and no major morbidity or mortality occurred in either group. Operative time (75,8 ± 33,1 min in large cases vs 75,8 ± 33,1 min in small cases) was similar in both groups (p = 0,61). The incidence of post-operative complications did not differ between the two groups. In details there were 21 out of 25 (84%) uncomplicated cases among small GISTs versus 17 out of 24 (70,8%) uncomplicated cases among large GISTs (p = 0,32). ConclusionThis matched-pair case control study demonstrates that laparoscopic wedge resection for large gastric GISTs is safe and effective, as demonstrated for small tumors.
