Most studies on delayed gastric emptying (DGE) after pancreatic surgery have been carried out after pancreatoduodenectomy. Information on DGE after left or distal pancreatectomy (DP) and the factors that cause it is very scarce.
We have conducted a systematic review in accordance with PRISMA guidelines using the descriptors “delayed gastric emptying” AND “distal pancreatectomy”, with no language limitations and date until December 31, 2024. To evaluate the quality of the non-randomized studies, we used the Newcastle-Ottawa Scale.
A total of 121 articles were obtained. Upon review, only 4 articles were relevant. They included 2549 patients, 52.9% of whom were women. A total of 228 presented DGE after DP, representing an incidence of 8.9%. The only factor related to DGE present in all series was the existence of a postoperative pancreatic fistula. The presence of abdominal collections, laparotomy approach used, multivisceral resection, older patients, tumor vascular involvement, and drains have been related to DGE after DP in some of the 4 articles studied.
The incidence of DGE after DP is close to 10%. Therefore, it should be systematically evaluated in any DP series. Among the factors associated with DGE, postoperative pancreatic fistula is the only confirmed factor contributing to its development. More studies are needed to evaluate these factors and thus reduce their incidence.
