Severity of Pancreatic Leak in Relation to Gut Restoration After Pancreaticoduodenectomy

Background:. Pancreatic leak after pancreaticoduodenectomy and gut restoration via a single jejunal loop remains the crucial predictor of patients’ outcome. Our reasoning that active pancreatic enzymes may be more disruptive to the pancreatojejunostomy prompted us to explore a Roux-en-Y configuration for the gut restoration, anticipating diversion of bile salts away from the pancreatic stump. Our study aims at comparing two techniques regarding the severity of postoperative pancreatic fistula (POPF) and patients’ outcome. Methods:. The files of 415 pancreaticoduodenectomy patients were retrospectively reviewed. Based on gut restoration, the patients were divided into: cohort A (n = 105), with gut restoration via a single jejunal loop, cohort B (n = 140) via a Roux-en-Y technique assigning the draining of pancreatic stump to the short limb and gastrojejunostomy and bile (hepaticojejunostomy) flow to long limb, and cohort C (n = 170) granting the short limb to the gastric and pancreatic anastomosis, whereas hepaticojejunostomy was performed to the long limp. The POPF-related morbidity and mortality were analyzed. Results:. Overall POPF in cohort A versus cohorts B and C was 19% versus 12.1% and 9.4%, respectively (P = 0.01 A vs B + C). POPF-related morbidity in cohort A versus cohorts B and C was 10.5% versus 7.3% and 6.3%, respectively (P = 0.03 A vs B+C). POPF-related total hospital mortality in cohorts A versus B and C was 1.9% versus 0.8% and 0.59%, respectively (P = 0.02 A vs B+C). Conclusion:. Roux-en-Y configuration showed lower incidence and severity of POPF. Irrespective of technical skill, creating a gastrojejunostomy close to pancreatojejunostomy renders the pancreatic enzymes less active by leaping the bile salts away from the pancreatic duct and providing a lower pH

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide.Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters.Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 percent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 percent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 percent; however, it was 41 per cent in low-to-middle-compared with 19 per cent in very high-HDI countries.Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
