Abstract
Purpose:
Laparoscopic resection of submucosal tumors in the gastric fundus, especially in the posterior wall near the esophagocardiac junction (ECJ), is difficult and time consuming and is and likely to cause esophageal stenosis and splenic injury. In this article, we report an extraluminal laparoscopic wedge-resection (ELWR) that minimizes these problems.
Methods:
Thirty-seven patients with submucosal tumors in the posterior wall of the gastric fundus received ELWR. The operation consisted of four steps: 1) localization of the tumor, 2) dissection of the omentum, 3) mobilization of the gastric fundus/upper pole of the spleen and exposure of the ECJ, and 4) resection of the gastric fundus with a linear endoscopic gastrointestinal anastomosis stapler.
Results:
None of the cases needed conversion to open surgery. Mean postoperative hospital stay was 5.5 ± 1.0 days. The distance between the tumor and the incision margin ranged from 0.7 to 2.5 cm toward the ECJ. Pathologic examination revealed 7 cases of leiomyomas, 29 cases of stromal tumors (4 were low-grade malignant tumors), and 1 case of neurofibroma. There was no recurrence, metastasis, esophageal stenosis, or any other severe adverse event during the follow-up period (52 ± 3.1 months).
Conclusions:
ELWR is a safe, effective treatment for submucosal tumors in the posterior wall of the gastric fundus.
