Abstract
Background: Untreated pancreatic exocrine insufficiency (PEI) results in substantial patient harm. Upper gastrointestinal surgery (bariatric metabolic surgery and oesophagogastric resection) affects the delicate physiology of pancreatic exocrine function and may result in PEI. The aim of this study was to assimilate the literature on incidence, diagnosis, and management of PEI after bariatric metabolic surgery and oesophagogastric resection.
Methods: A systematic review of PubMed, MEDLINE, and Embase databases identified studies investigating PEI after non-pancreatic upper gastrointestinal surgery. Meta-analyses were undertaken for incidence of PEI and benefit of pancreatic enzyme replacement therapy.
Results: Among 1620 patients from 24 studies included in quantitative synthesis, 36.0% developed PEI. The incidence of PEI was 23.0 and 50.4% after bariatric metabolic surgery and oesophagogastric resection respectively. Notably, the incidence of PEI was 44% after biliopancreatic diversion with duodenal switch and 66.2% after total gastrectomy. The most common diagnostic test used was faecal elastase 1 (15 of 31 studies), with less than 200 µg/g being diagnostic of PEI. A total of 11 studies considered the management of pancreatic exocrine insufficiency, with 78.6% of patients responding positively to pancreatic enzyme replacement when it was prescribed.
Conclusion: PEI is common after non-pancreatic upper gastrointestinal surgery and patients may benefit from enzyme replacement therapy.
