Technical Details and Results of a Modified End-to-Side Technique of Pancreatojejunostomy: a Personal Series of 100 Patients.

<bold>Background: </bold>The treatment of pancreatic stump is a critical step of pancreatoduodenectomy (PD) because leaks from this anastomosis incur major morbidity and mortality. We describe the technical details of a modified end-to-side pancreatojejunostomy (mPJ), and report on the outcome of the first 100 patients.<bold>Methods: </bold>From October 2008 to June 2017, 424 pancreatic resections were performed, of which 203 were PD. The mPJ was introduced in November 2010 and used in 100 consecutive patients, by a single surgeon. Data were retrieved from a prospectively collected Institutional database, and used for the present retrospective evaluation. Post-operative pancreatic fistulas (POPF) were stratified with the Fistula Risk Score (FRS), based on the 2005-International Study Group of Pancreatic Fistula classification (ISGPFc) and on the subsequent 2016-revised version (ISGPSc).<bold>Results: </bold>ISGPFc POPF occurred in 17/100 (17%): grade A in 10/100 (10%), grade B in 6/100 (6%) and grade C in 1/100 (1%). On the ISGPSc, POPF rate averaged 7%: grade B in 6/100 (6%) and grade C in 1/100 (1%). POPF rate associated with high FRS was 18.8%/6.3% (ISGPFc/ISGPSc). With low and intermediate FRS, POPFs were 5.3%/0% (ISGPFc/ISGPSc) and 21.3%/9.8% (ISGPFc/ISGPSc) respectively. Re-operation rate was 3%. In-hospital mortality rate was 2% and specific mortality rate for POPF was 1%.<bold>Conclusions: </bold>The mPJ technique is associated with a POPF rate which was less than expected, especially for "difficult" pancreas with high FRS (soft gland texture and small duct). A larger prospective series is needed in addition to comparative studies with other techniques for robust assessment. [ABSTRACT FROM AUTHOR]
