BACKGROUND The management of cystic dystrophy of the duodenal wall(CDDW),or groove pancreatitis(GP),remains *** pancreatoduodenectomy(PD)is considered the most suitable operation for CDDW,pancreas-preserving duodenal resection(PPDR)has also been suggested as an alternative for the pure form of GP(isolated CDDW).There are no studies comparing PD and PPDR for this *** To compare the safety,efficacy,and short-and long-term results of PD and PPDR in patients with *** A retrospective analysis of the clinical,radiologic,pathologic,and intra-and postoperative data of 84 patients with CDDW(2004-2020)and a comparison of the safety and efficacy of PD and *** Symptoms included abdominal pain(100%),weight loss(76%),vomiting(30%)and jaundice(18%)and data from computed tomography,magnetic resonance imaging,and endoUS led to the correct preoperative diagnosis in 98.8%of *** patients were treated conservatively with pancreaticoenterostomy(n=8),duodenum-preserving pancreatic head resection(n=6),PD(n=44)and PPDR(n=15)without *** gain was significantly higher after PD and PPDR and complete pain control was achieved significantly more often after PPDR(93%)and PD(84%)compared to the other treatment modalities(18%).New onset diabetes mellitus and severe exocrine insufficiency occurred after PD(31%and 14%),but not after *** PPDR has similar safety and better efficacy than PD in patients with CDDW and may be the optimal procedure for the isolated form of *** pure form of GP is a duodenal disease and PD may be an overtreatment for this *** detection of CDDW provides an opportunity for pancreas-preserving surgery.
