A Prospective, Dual-Center Trial of Circumferential Radiofrequency Ablation of Anal High-Grade Squamous Intraepithelial Lesions Demonstrate Improved Long-term Efficacy Over Historical Controls of Targeted Ablation.

Background: Targeted ablation of anal canal high-grade dysplasia results in high recurrence over time. Circumferential radiofrequency ablation might decrease recurrence.

Objective: This study aimed to determine the safety and efficacy of circumferential radiofrequency ablation for anal high-grade dysplasia.

Retrorectal teratoma: a rare cause of pain in the tailbone.

Retrorectal tumors are extremely rare and heterogeneous, requiring complete surgical excision for definitive diagnosis and optimal outcome. We describe a patient presenting with chronic "tailbone pain" who was found to have a benign cystic teratoma in the presacral space. She underwent en bloc resection and recovered well.

Multidisciplinary management of colorectal cancer enhances access to multimodal therapy and compliance with National Comprehensive Cancer Network (NCCN) guidelines.

Purpose: Multidisciplinary teams have become increasingly desirable for managing complex disease but little objective data exist to support this approach. The aim of our study was to determine the impact of a multidisciplinary clinic on the management of colorectal cancer.

Methods: Data were prospectively collected on all patients with newly diagnosed colorectal cancer referred to the multidisciplinary clinic at our institution in 2009 and compared to a control group of all patients managed outside the clinic from 2008 to 2009.

Endoprosthetic management of refractory ileocolonic anastomotic strictures after resection for Crohn's disease: report of nine-year follow-up and review of the literature.

Background: The role of endoluminal stenting in benign obstruction, especially for Crohn's disease (CD), is controversial, with limited data and widely disparate outcomes. The purpose of this study was to determine the long-term efficacy and safety of this technology in the treatment of fibrostenotic CD and to review the existing literature on this topic.

Methods: We undertook a retrospective review of all patients undergoing endoluminal stenting for CD strictures at our institution from 2001 to 2010.

Traumatic transection of the pancreas. A case of delayed presentation.

Context: Isolated traumatic injuries to the pancreas are extremely unusual and diagnosis may be difficult due to delay in presentation and subtlety of symptoms.

Case Report: We describe a patient who presented 24 hours after sustaining blunt abdominal trauma and was found to have a complete pancreatic neck transection on computed tomography with no other injuries. The patient underwent a distal pancreatectomy and splenectomy which was complicated by a postoperative abscess on day 15.
