Background: Because involvement is extremely rare, surgery for gastric stro
mal tumors consists of local excision with clear resection margins. The aim
of this study was to report the results of a consecutive series of nine pa
tients with posterior gastric stromal tumors that were excised using a mini
mally invasive method.
Methods: Patients received a general anesthetic before placement of three l
aparoscopic ports- a 10-mm (umbilical) port for the telescope and two worki
ng ports, a 12-mm port (left upper quadrant) and a IO-mm port (right upper
quadrant). Grasping forceps were placed through an anteriorly placed gastro
tomy to deliver the tumor through the gastrotomy into the abdominal cavity,
thus allowing an endoscopic linear cutter to excise the tumor with a cuff
of normal gastric tissue.
Results: Nine consecutive patients with a median age of 73 years (range, 47
-83) were treated. In seven patients, laparoscopic removal of the tumor was
achieved. Two patients required conversion to an open operation because th
e tumor could not be delivered into the abdominal cavity. The median length
of postoperative stay for the seven patients in whom the procedure was com
pleted laparoscopically was 3 days (range, 2-6).
Conclusions: Posterior gastric stromal tumors can be removed safely using t
his minimally invasive method. Delivery of the tumor through the gastrotomy
is essential for success.
