Primary retroperitoneal mucinous cystic tumors (PRMCT) are divided into 3 groups: benign, borderline malignancy, and malignant. We report a rare case of benign retroperitoneal mucinous cystadenoma of a 59-year-old Caucasian female who presented to our clinic with moderate intermittent left upper quadrant abdominal pain for several months, accompanied by early satiety, and unintentional weight loss of 10 pounds. An abdominal contrast-enhanced computed tomography (CT) scan indicated the presence of a 6.5 × 8.8 cm multilobulated mass in the left upper quadrant, characterized by a homogenous appearance with smooth margins. Upper endoscopic ultrasound and fine needle aspiration were performed. Cytology and histology results yielded rare inflammatory cells and debris with no cytological evidence of malignancy. The case was discussed at the hepatopancreatobiliary conference; the patient underwent a robotic resection of the mass with a gastric rim. Primary retroperitoneal mucinous cystadenomas are commonly managed by complete surgical excision. Robotic excision presents an alternative approach for handling this uncommon neoplastic lesion., (© 2024 The Authors. Published by Elsevier Inc. on behalf of University of Washington.)

Introduction: Although a volume-outcome relationship has been well established for pancreatectomy, little is known about differences in mortality by facility type. The objective of this study is to evaluate the impact of facility type on short-term and long-term survival outcomes for patients with pancreatic adenocarcinoma who underwent pancreatectomy and identify determinants of overall survival (OS)., Methods: A cohort of 33,382 patients with Stage I-III pancreatic adenocarcinoma diagnosed between 1998 and 2011 were evaluated from the National Cancer Data Base. Clinicopathological, sociodemographic and treatment variables were compared among three facility types where patients received resection: (i) community cancer program (CCP), (ii) comprehensive community cancer program (CCCP), and (iii) academic research program (ARP). 5-year OS was calculated using the Kaplan-Meier method., Results: Despite ARP having significantly higher percentage of poorly differentiated tumors, higher T-stage tumors, more positive lymph nodes, and greater circle distance compared to the other facilities, it had the highest 5-yr OS. The 5-yr OS for CCP, CCCP, and ARP was 11.2%, 13.2%, and 16.6%, respectively (P < 0.0001) and the median survival time (months) was 12.4, 15.6 and 19.1, respectively., Conclusion: Patients receiving pancreatic resection at an ARP yielded a higher 5-year OS compared to CCP or CCCP., (Published by Elsevier Ltd.)

We present a 42-year-old male with strictured bilioenteric anastomosis after bile duct injury repair. The patient improved after percutaneous biliary drainage and balloon dilation of the stricture. Persistent bile reflux around the catheter insertion site prompted a cholangiogram that suggested an error in the enteric limb. Surgical exploration revealed that a torsed ileal loop was used for bilioenteric anastomosis. This error was repaired surgically. The patient had immediate and long-term resolution of symptoms., (Copyright © 2015 Elsevier Inc. All rights reserved.)
