Purpose
Duodenal gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the gastrointestinal tract. For localized or potentially resectable GISTs, surgery is the first choice. But the important and complex anatomical structure adjacent to the duodenum makes surgical management for duodenal GISTs challenging and few comprehensive surgical strategies have been described. This study aims to provide new comprehensive surgical strategies for duodenal GISTs by summarizing the surgical approaches and outcomes of duodenal GISTs in different locations in our center in the past 11 years.
Methods
Information from patients who underwent surgical resection for duodenal GISTs at our facility during the past 11 years was retrospectively analyzed.
Results
Ninety-two patients have received surgical procedures in the facility. Twenty-three, 31, 3, and 35 patients underwent wedge resection, segmental resection, pancreatic head-preserving duodenectomy, and pancreaticoduodenectomy, respectively. The mean operative times were 212.6 (150–270), 260 (180–370), 323 (300–350), and 354.9 (290–490) min; the mean blood loss was 226.1 (100–400), 303.2 (100–600), 500 (400–600), and 582.9 (200–1300) ml, respectively. R0 margins were obtained in 21, 29, 3, and 32 patients, respectively.
Conclusions
For duodenal GISTs without invasion of the ampulla of Vater or the pancreatic head, a limited resection (such as wedge resection, segmental resection, or pancreatic head-preserving duodenectomy) is feasible. For duodenal GISTs with an invasion of the ampulla of Vater or the pancreatic head, a pancreaticoduodenectomy is still necessary.
