Prophylactic Mesh for Hernia Prevention: Has the Time Arrived?

Incisional and parastomal hernias continue to be vexing problems for patients and surgeons. Risk factors are generally patient-related and/or technical in nature, and in some cases, can be altered, resulting in improved outcomes. Improved fascial closure techniques can only partly reduce the risk of incisional hernia formation.

Diagnostic Accuracy of Selective 3-T MR Neurography-guided Retroperitoneal Genitofemoral Nerve Blocks for the Diagnosis of Genitofemoral Neuralgia.

Purpose To determine if 3-T magnetic resonance (MR) neurography-guided retroperitoneal genitofemoral nerve (GFN) blocks are safe and effective for the diagnosis of genitofemoral neuralgia. Materials and Methods Following institutional review board approval and informed consent, 26 subjects (16 men, 10 women; mean age, 42 years [range, 24-78 years]; mean body mass index, 28 kg/m [range, 20-35 kg/m]) with intractable groin pain were included. By using a 3-T MR imaging system, intermediate-weighted turbo spin-echo pulse sequences, and MR-conditional needles, diagnostic MR neurography-guided GFN blocks were performed in the retroperitoneum.

Long-Term Outcomes of 98 Surgically Resected Metastatic Tumors in the Pancreas.

Purpose: The goal of this study was to assess the outcomes and characteristics of patients who underwent pancreatectomy for metastatic disease to the pancreas.

Methods: Patients who underwent surgical resection of metastatic disease to the pancreas from 1988 to 2016 were identified using a prospectively maintained database. Data on clinicopathological features and outcomes of these patients were analyzed.

Re-evaluating the impact of tumor size on survival following pancreaticoduodenectomy for pancreatic adenocarcinoma.

Background And Objectives: Following resection of pancreatic adenocarcinoma, tumor size has been considered a key prognostic feature; however, this remains controversial. We sought to examine the association of size with outcomes following resection of pancreatic adenocarcinoma.

Methods: Between 1970 and 2010, 1,697 patients with pancreatic adenocarcinoma at the Johns Hopkins Hospital underwent curative intent pancreaticoduodenectomy.

Unusual causes of benign biliary strictures with cholangiographic features of cholangiocarcinoma.

Focal strictures occurring at the hepatic duct confluence, or within the common hepatic duct or common bile duct in patients without a history of prior surgery in that region or stone disease, are usually thought to represent cholangiocarcinoma until proved otherwise. However, not uncommonly, patients undergo surgical exploration for a preoperative diagnosis of cholangiocarcinoma, based on the cholangiographic appearance of the lesion, only to find histologically that the stricture was benign in nature. Despite sophisticated radiographic, endoscopic, and histologic studies, it is often impossible before laparotomy to distinguish malignant from benign strictures when they have the characteristic radiographic appearance of cholangiocarcinoma.
