A Band Lifting Assisted Method for Laparoscopic Resection of Gastrointestinal Stromal Tumors on the Posterior Wall of the Stomach

Laparoscopic surgical techniques are beneficial for the wedge resection of gastrointestinal stromal tumors (GISTs). We have developed a new technique of laparoscopic transgastric resection for GISTs of the posterior wall of the stomach, a band lifting wedge resection method that has been confirmed to ensure sufficient surgical margins around the resected specimen in 21 cases. GISTs located at the posterior wall of the stomach were collected for this study. Laparoscopic anterior gastrotomy was performed and a 9-Fr rubber band was looped around the base of the tumor, allowing it to be lifted up through the anterior gastrotomy. The lesion was transected using a laparoscopic linear cutter and the gastrotomy was then closed by sequential application of the linear cutter. Surgical specimens were examined immunohistochemically All GISTs were successfully and completely resected using the laparoscopic technique. The resected tumors were ellipse-shaped or round. Macroscopic examination of the resected specimens showed complete tumor excision with negative surgical margins in all patients. A band lifting method for transection of GISTs on the posterior wall of the stomach easily allows for sufficient surgical margins of GISTs. The technique is reliable and feasible for laparoscopic treatment of GISTs in the stomach.

Operative Findings

Gastrointestinal stromal tumors (GISTs) are malignant and rare form of soft tissue sarcoma of the digestive tract. The incidence of gastrointestinal stromal tumors is very low Kramer et al. 2005 Jejunal GISTs are extremely rare. Here we present a rare case of jejunal GIST with unusually large size at presentation. The patient presented with severe abdomen pain, exophytic growth, and dimorphic anemia. Surgical resection of the tumor was carried out, and operative findings revealed a 15 × 10 cm growth, arising from serosal surface of jejunum, at the antimesenteric surface. Diagnosis in this case was made by subjecting the resected specimen to immunohistochemical analysis. In view of large size of the resected tumor, and high-risk histopathological features, imatinib mesylate 400 mg once daily was given as adjuvant chemotherapy. Patient is asymptomatic without any evidence of tumor recurrence after six months of postoperative followup. Imatinib as such is recommended in metastatic, residual or recurrent cases of GISTs or which are surgically not removable; however, recent recommendations suggests the use of imatinib mesylate after radical surgery in high-risk cases, because it has shown a significant decrease in the recurrence rate, and the Food and Drug Administration (FDA) has also approved the use of imatinib as adjuvant therapy after complete resection of localized, primary GIST.
