Duodeno-jejunal or gastro-enteric leakage after pancreatic resection: a case–control study

Effect of preoperative nutritional supplementation on postoperative outcomes for patients undergoing pancreaticoduodenectomy for cancer: a systematic review protocol

OBJECTIVE

This review aims to present the best available evidence related to the effect of preoperative nutritional supplementation on postoperative outcomes for patients undergoing pancreaticoduodenectomy for cancer.

INTRODUCTION

Pancreaticoduodenectomy surgery is the only curative option for early head of pancreas and periampullary cancers. This complex, high-risk procedure is associated with significant morbidity, making opportunities to improve outcomes paramount. Nutritional supplementation in the preoperative period may enhance the body's ability to withstand the stress of major surgery and reduce postoperative complications.

INCLUSION CRITERIA

This review will consider studies of patients undergoing pancreaticoduodenectomy for cancer who are provided preoperative nutritional supplementation in any form for a minimum of 48 hours. Randomized and quasi-randomized trials that compare any form of preoperative nutritional supplementation to standard care in these patients will be included. Outcome data will include hospital length of stay, mortality, infections, delayed gastric emptying, pancreatic fistula, anastomotic leak, hemorrhage, weight loss, body mass index, serum albumin, lymphocyte levels, and nutrition risk index score.

METHODS

Electronic databases (PubMed, Scopus, CINAHL, and Cochrane Library) and trial registers will be searched for published and unpublished articles. All articles from database inception to present, published in any language will be included. One reviewer will perform the literature search, screen texts for inclusion, and extract data. Two authors will assess methodological quality of the literature using the JBI critical appraisal tool. Authors will be contacted where additional data or clarification is required. Statistical meta-analysis through synthesis and pooling of data for each intervention will be completed where meaningful.

Gastro- or Duodenojejunostomy Leaks After Pancreatoduodenectomy: Single Center Experience and Narrative Literature Review

BACKGROUND AND METHODS

Gastro- or duodenojejunostomy leaks after pancreatoduodenectomy is rare. This study aims to analyze the incidence, management, and outcome of gastro- or duodenojejunostomy leaks after pancreatoduodenectomy based on a single center experience from 2004 to 2020 with a narrative literature review.

RESULTS

Of a total of 1494 pancreatoduodenectomies, eight patients with gastrojejunostomy (n=1) or duodenojejunostomy (n=7) leak were identified from the institutional pancreatic database. All leaks were treated operatively. In two patients dismantling of the duodenojejunostomy, distal gastrectomy, and closure of the pyloric and jejunal side, a percutaneous endoscopic gastrostomy and a feeding jejunostomy ultimately had to be performed after an unsuccessful attempt of gastrojejunostomy and suture of the duodenojejunostomy, respectively. The literature search revealed three more studies specifically addressing this complication after pancreatoduodenectomy (36 patients of a total of 4739 pancreatoduodenectomies). Based on an analysis of the current study and the literature review, the overall incidence of gastro- or duodenojejunostomy leaks after pancreatoduodenectomy was 0.71 % (44/6233 pancreatoduodenectomies). The occurrence of a gastro- or duodenojejunostomy leak was associated with a concomitant postoperative pancreatic fistula in 50 % of the cases, an increased length of hospital stay, and a mortality rate of 15.9 %. Surgical treatment was performed in 84 % of the cases.

CONCLUSION

Gastro- or duodenojejunostomy leak is a rare complication after pancreatoduodenectomy. Prompt diagnosis and early repair is important. In most cases, a surgical intervention is necessary for a good outcome. Under salvage conditions, a bailout strategy may be to temporarily dismantle the gastro- or duodenojejunal anastomosis.
