Limited resection for duodenal gastrointestinal stromal tumors: Surgical management and clinical outcome

Figure 2 Illustration of the different techniques for limited resection of duodenal gastrointestinal stromal tumors. Wedge resection was performed for small tumors and for larger tumors with only a small-area base at the duodenal wall in all parts of the duodenum. Wedge resection with reconstruction of the defect at the duodenal wall by duodenojejunostomy was performed in patients with larger defects of the second part of the duodenum after tumor resection. Segmental duodenectomy was carried out for larger tumors of the third or fourth part of the duodenum.
