Background: The lymph node (Ln) status of patients with resectable pancreatic ductal adenocarcinoma is an important predictor of survival. The survival benefit of extended lymphadenectomy during pancreatectomy is, however, disputed, and there is no true definition of the optimal extent of the lymphadenectomy. The aim of this study was to formulate a definition for standard lymphadenectomy during pancreatectomy., Methods: During a consensus meeting of the International Study Group on Pancreatic Surgery, pancreatic surgeons formulated a consensus statement based on available literature and their experience., Results: The nomenclature of the Japanese Pancreas Society was accepted by all participants. Extended lymphadenectomy during pancreatoduodenectomy with resection of Ln's along the left side of the superior mesenteric artery (SMA) and around the celiac trunk, splenic artery, or left gastric artery showed no survival benefit compared with a standard lymphadenectomy. No level I evidence was available on prognostic impact of positive para-aortic Ln's. Consensus was reached on selectively removing suspected Ln's outside the resection area for frozen section. No consensus was reached on continuing or terminating resection in cases where these nodes were positive., Conclusion: Extended lymphadenectomy cannot be recommended. Standard lymphadenectomy for pancreatoduodenectomy should strive to resect Ln stations no. 5, 6, 8a, 12b1, 12b2, 12c, 13a, 13b, 14a, 14b, 17a, and 17b. For cancers of the body and tail of the pancreas, removal of stations 10, 11, and 18 is standard. Furthermore, lymphadenectomy is important for adequate nodal staging. Both pancreatic resection in relatively fit patients or nonresectional palliative treatment were accepted as acceptable treatment in cases of positive Ln's outside the resection plane. This consensus statement could serve as a guide for surgeons and researchers in future directives and new clinical studies., (Copyright © 2014 Mosby, Inc. All rights reserved.)

Introduction: Operative complications after pancreatoduodenectomy can be managed by nonoperative or operative interventions. The aim of this study was to analyze the shift in management of five major complications and their success rates. An algorithm was developed according to predictors for type of intervention and failure of management., Methods: From 1992-2012, patients with pancreaticojejunostomy, hepaticojejunostomy or gastroenterostomy leakage, postpancreatectomy hemorrhage, or primary abscess after pancreatoduodenectomy were selected from a prospectively maintained database. Complications were treated by nonoperative or operative intervention Two cohorts were created according to period of index operation. Pre- and postoperative characteristics were analyzed., Results: Of 1,037 patients, 263 (25%) experienced operative complications. The incidence of pancreatic fistula increased from 11 to 18%, accompanied by a shift from operative toward nonoperative management. This was also seen in the management of late hemorrhage. Success rates of interventions remained similar for all complications. The incidence of primary abscesses decreased. Early sepsis (odds ratio [OR] 17.8, 95% confidence interval [CI] 4.9-64.4) was associated with failure of nonoperative interventions in patients with pancreatic fistula. Hemodynamic instability (OR 17.2, 95% CI 1.8-160.1) and sepsis (OR 6.7, 95% CI 2.7-16.3) were predictive for operative intervention. Failure of nonoperative intervention (HR 3.95% CI 1.3-7.1) and operative intervention (HR 6.4 95% CI 3.2-12.8) were predictors for poor survival., Conclusion: The shift towards nonoperative interventions was notable in patients suffering from pancreaticojejunostomy leakage and late hemorrhage. Anastomotic leakage, late hemorrhage, and primary abscesses can be managed nonoperatively however; hemodynamic instability and early sepsis are strong arguments to perform surgery., (Copyright © 2014 Mosby, Inc.

Background: Common anastomotic complications after pancreatoduodenectomy (PD) are leakage from the pancreaticojejunostomy or hepaticojejunostomy. Leakage from the gastroenteric anastomosis has rarely been described. We evaluated the incidence of gastroenteric leakage after PD and described its presentation, treatment, and outcome., Methods: Between 1992 and 2012, a consecutive series of 1,036 patients underwent PD in the Academic Medical Center. By use of a prospective database and medical records, we identified patients with gastroenteric leakage. Clinicopathologic data were compared with patients without gastroenteric leakage, and presentation, radiologic findings, treatment, and outcome of gastroenteric leaks were analyzed., Results: Twelve patients (1.2%) had gastroenteric leakage. Patients with gastroenteric leaks had undergone longer operative procedures, had more pancreatic fistulas and other complications, and had a significantly longer hospital stay. Median postoperative day of diagnosis was 8 (range, 2-23). Clinical signs included tender abdomen and high drain output suspicious of gastric content. Common radiologic findings were pneumoperitoneum and intra-abdominal fluid. Seven patients (58%) were treated operatively, 4 (33%) by percutaneous drainage, and 1 (8%) underwent no specific treatment duo to his poor clinical condition. This patient died in hospital, resulting in a hospital mortality of 8%., Conclusion: Gastroenteric leakage after PD is rare. Clinical presentation is not specific, unlike leakage from other sites. Drain output suspicious of gastric content may help to differentiate from pancreatic or hepatic anastomotic leakage. It may be associated with a longer duration of operation and concomitant pancreatic fistula. A good outcome depends on prompt diagnosis and is mostly achieved by operative intervention., (Copyright © 2014 Mosby, Inc. All rights reserved.)
