Neuroendocrine tumors (NETs) involve the genitourinary system in less than 1% of cases, with primary renal carcinoids comprising only 19% of reported genitourinary NETs (56 cases worldwide). We report a case of a renal NET presenting as a large renal mass with extensive local invasion, requiring definitive radical en bloc resection via a thoracoabdominal approach.

BACKGROUND Endoscopic submucosal dissection (ESD) is a technique for en bloc resection of superficial tumors of the gastrointestinal tract. In contrast to Japan and other Asian countries, few data are available in Western countries. The objective of the current study was to evaluate the experience of ESD in a single Australian tertiary center. METHODS The patient features, outcomes and compli...

Horses with extensive or invasive tumors of the external genitalia may require surgical intervention for successful treatment. Solitary tumors may be removed completely by local excision, laser ablation, cryotherapy, or circumferential posthectomy (i.e., reefing). Horses with advanced lesions involving the glans or body of the penis warrant phallectomy, whereas horses with infiltrative lesions ...

OBJECTIVE To document what can be accomplished with surgical resection done according to the classical principles of surgical oncology. METHODS One hundred consecutive patients underwent en bloc esophagectomy for esophageal adenocarcinoma. No patient received pre- or postoperative chemotherapy or radiation therapy. Tumor depth and number and location of involved lymph nodes were recorded. A l...

Introduction: A novel electrosurgical generator unit (ESU), ConMed Beamer, was recently introduced to facilitate endoscopic submucosal dissection (ESD) by employing Automatic Cutting Effect (ACE) technology. Its use in endoscopy has yet be investigated. Background and study aims: The aim of this evaluate the feasibility safety performing ESD per-oral myotomy (POEM) using settings generated with...

CONTEXT Endoscopic mucosal resection is a minimally invasive technique used in the treatment of colorectal neoplasms, including early carcinomas of different size and morphology. OBJECTIVES To evaluate procedure safety, efficacy, outcomes, and recurrence rate in endoscopic mucosal resection of colorectal lesions. METHODS A total of 172 lesions in 156 patients were analyzed between May 2003 ...

OBJECTIVES: This study sought to determine the clinical and pathological factors associated with perioperative morbidity, mortality and oncological outcomes after multivisceral en bloc resection in patients with colorectal cancer. METHODS: Between January 2009 and February 2014, 105 patients with primary colorectal cancer selected for multivisceral resection were identified from a prospective...

BACKGROUND AND STUDY AIMS Local recurrence has been observed after endoscopic mucosal resection (EMR) of nonpedunculated colorectal lesions. The indications for follow-up colonoscopy and the optimal time interval are currently unclear. The aims of this systematic review were to assess the frequency of local recurrence after EMR, to identify risk factors for recurrence, and to provide follow-up ...

OBJECTIVES Endoscopic submucosal dissection (ESD) has advantages over conventional endoscopic mucosa resection. The number of elderly patients (more than 75 years old) with early gastric cancer (EGC) has been steadily increasing. We sought to assess clinical outcomes of ESD for EGC in elderly. METHODS ESD was performed for patients with EGC, who fulfilled the criteria for ESD: mucosal cancer ...

Background and study aims: Endoscopic submucosal dissection (ESD) is an advanced endoscopic technique that allows en-bloc resection of gastrointestinal tumor. We systematically review the medical literature in order to evaluate the safety and efficacy of colorectal ESD. Patients and methods: We performed a comprehensive literature search of MEDLINE, EMBASE, Ovid, CINAHL, and Cochrane for studie...
