Clinical Outcomes After Total Pancreatectomy: A Prospective Multicenter Pan-European Snapshot Study.

OBJECTIVE: To assess outcomes among patients undergoing total pancreatectomy (TP) including predictors for complications and in-hospital mortality. BACKGROUND: Current studies on TP mostly originate from high-volume centers and span long time periods and therefore may not reflect daily practice. METHODS: This prospective pan-European snapshot study included patients who underwent elective (primary or completion) TP in 43 centers in 16 European countries (June 2018-June 2019). Subgroup analysis included cutoff values for annual volume of pancreatoduodenectomies (<60 vs ≥60).Predictors for major complications and in-hospital mortality were assessed in multivariable logistic regression. RESULTS: In total, 277 patients underwent TP, mostly for malignant disease (73%). Major postoperative complications occurred in 70 patients (25%). Median hospital stay was 12 days (IQR 9-18) and 40 patients were readmitted (15%). In-hospital mortality was 5% and 90-day mortality 8%. In the subgroup analysis, in-hospital mortality was lower in patients operated in centers with ≥60 pancreatoduodenectomies compared <60 (4% vs 10%, P = 0.046). In multivariable analysis, annual volume <60 pancreatoduodenectomies (OR 3.78, 95% CI 1.18-12.16, P = 0.026), age (OR 1.07, 95% CI 1.01-1.14, P = 0.046), and estimated blood loss ≥2L (OR 11.89, 95% CI 2.64-53.61, P = 0.001) were associated with in-hospital mortality. ASA ≥3 (OR 2.87, 95% CI 1.56-5.26, P = 0.001) and estimated blood loss ≥2L (OR 3.52, 95% CI 1.25-9.90, P = 0.017) were associated with major complications. CONCLUSION: This pan-European prospective snapshot study found a 5% inhospital mortality after TP. The identified predictors for mortality, including low-volume centers, age, and increased blood loss, may be used to improve outcomes.

Intra-arterial bolus octreotide administration during Whipple procedure in patients with fragile pancreas: a novel technique for safer pancreaticojejunostomy.

BACKGROUND AND OBJECTIVES: Leakage from the pancreaticojujenostomy is the most serious complication of Whipple. Pancreatic fistula rate is higher in cases of fragile pancreas often seen in duodenal carcinomas and carcinomas of the ampulla of Vater. Octreotide administration has been used for the prevention of fistula formation through the subcutaneous route. Due to its physiologic effects to the pancreatic parenchyma the intra-arterial administration of octreotide could provide tissue hardening that allows for a technically easier anastomosis while maintaining its protective role for fistula formation. METHODS: Octreotide was injected directly into the distal part of the gastroduodenal artery (GDA) in four patients undergoing Whipple for histologically proven periampullary cancer. RESULTS: Tissue hardening after octreotide administration was evident not only in surgeons' hands but in the intra-operative ultrasound as well. The three patients were discharged on day 9, 11, and 13; they had an uneventful postoperative course, while one patient had a minor bile leak from the choledojejunal anastomosis and was discharged on day 22. CONCLUSIONS: The intra-arterial administration of octreotide during Whipple is a safe procedure and provides tissue hardening thus making the performance of the anastomosis technically easier. The actual benefit in terms of morbidity, mortality, and fistula rate are to be further evaluated.

Somatostatin versus octreotide in the treatment of patients with gastrointestinal and pancreatic fistulas.

BACKGROUND AND PURPOSE: Gastrointestinal and pancreatic fistulas are characterized as serious complications following abdominal surgery, with a reported incidence of up to 27% and 46%, respectively. Fistula formation results in prolonged hospitalization, increased morbidity/mortality and increased treatment costs. Conservative and surgical approaches are both employed in the management of these fistulas. The purpose of the present study was to assess, evaluate and compare the potential clinical benefit and cost effectiveness of pharmacotherapy (somatostatin versus its analogue octreotide) versus conventional therapy. PATIENTS AND METHODS: Fifty-one patients with gastrointestinal or pancreatic fistulas were randomized to three treatment groups: 19 patients received 6000 IU/day of somatostatin intravenously, 17 received 100 microg of octreotide three times daily subcutaneously and 15 patients received only standard medical treatment. RESULTS: The fistula closure rate was 84% in the somatostatin group, 65% in the octreotide group and 27% in the control group. These differences were of statistical significance (P=0.007). Overall mortality rate was less than 5% and statistically significant differences in mortality among the three groups could not be established. Overall, treatment with somatostatin and octreotide was more cost effective than conventional therapy (control group), and somatostatin was more cost effective than octreotide. The average hospital stay was 21.6 days, 27.0 and 31.5 days for the somatostatin, octreotide and control groups, respectively. CONCLUSIONS: Data suggest that pharmacotherapy reduces the costs involved in fistula management (by reducing hospitalization) and also offers increased spontaneous closure rate. Further prospective studies focusing on the above parameters are needed to demonstrate the clinicoeconomic benefits.
