Surveillance and Survivorship after Treatment for Colon Cancer.

Colorectal cancer is the third most common cancer diagnosed in the United States. Majority of patients have localized disease that is amenable to curative resection. Disease recurrence remains a major concern after resection.

Current status: new technologies for the treatment of patients with fecal incontinence.

Fecal incontinence is a frequent and debilitating condition that may result from a multitude of different causes. Treatment is often challenging and needs to be individualized. During the last several years, new technologies have been developed, and others are emerging from clinical trials to commercialization.

Is the abdominal repair of rectal prolapse safer than perineal repair in the highest risk patients? An NSQIP analysis.

Background: Although the perineal approach in the surgical management of rectal prolapse has a higher recurrence, it is the accepted approach for higher-risk patients because of its lower morbidity.

Objective: The aim of this study was to determine outcomes of abdominal versus perineal approaches to rectal prolapse repair. DESIGN SETTINGS: A retrospective study was performed comparing outcomes of patients undergoing different types of surgical approaches (open abdominal, laparoscopic, perineal) for rectal prolapse.

Virtual three-dimensional computed tomography assessment of the gastric pouch following laparoscopic Roux-Y gastric bypass.

Background: The construction of the gastric pouch during surgery is largely based on the prevailing dogma of Roux-Y gastric bypass (RYGB) surgery. The scarce data that exist suggest that the smaller the gastric pouch, the greater the weight loss after surgery. Current estimations of pouch volume have inherent limitations.

A new modality to evaluate the gastric remnant after Roux-en-Y gastric bypass.

Background: Gastric bypass surgery has become one of the most common operations performed in the United States. Exclusion of the gastric remnant has raised concerns about the difficulty for future evaluation of mucosal-based lesions. Current methods include retrograde endoscopy, which is technically challenging, or a surgically created gastrotomy.

Laparoscopic gastric wedge resection for Dieulafoy's disease following preoperative endoscopic localization with India ink and endoscopic clips.

Background: Dieulafoy's lesion is a vascular malformation, usually of the stomach but occasionally of the small or large bowel. It is an uncommon, but clinically significant, source of upper gastrointestinal hemorrhage. Three cases have been reported in the literature of laparoscopic gastric wedge resection of these lesions by using intraoperative endoscopic localization.

The postoperative surveillance of patients with colon cancer and rectal cancer.

Background: Colon cancer is relatively common; however, the results of treatment have marginally improved over the last half century. Though about 85% of patients have colorectal tumors resected with curative intent, a significant number of these patients will eventually die from cancer. As a result, many clinicians have advocated intensive follow-up in such patients as an attempt to increase survival.

Colorectal manifestations of collagen vascular disease.

Background: The collagen vascular diseases are a collection of conditions, which are thought to be secondary to pathologic alterations in the immune system. Deposition of immune complexes in blood vessel walls resulting in either ischemia or thrombosis is the most widely accepted pathologic mechanism. The lack of familiarity with this subgroup of disease can lead to unnecessary surgical intervention.

The role of arachidonic acid regulatory enzymes in colorectal disease.

Purpose: Nonsteroidal anti-inflammatory drugs have a wide ranging effect on diseases of the colon and rectum. Interestingly, nonsteroidal anti-inflammatory drugs seem to play a beneficial role in colorectal cancer chemoprevention and adenoma regression, but may have a deleterious effect in inflammatory bowel disease. Prostaglandin inhibition is central to both the beneficial and toxic effects of this class of drugs.

The management of rectal cancer in the elderly.

Introduction: The majority of patients with rectal cancer are elderly. Due to the increasingly aging population the number of people with colorectal cancer is increasing. As medical advances in the areas of local therapy, radiation therapy, and surgical technique, such as, laparoscopy are made more elderly patients are offered various types of treatment for rectal cancer.

ANGIOACCESS FOR HAEMODIALYSIS IN RENAL FAILURE-AN ANALYSIS OF THE ROLE OF THE BRESCIA-CIMINO FISTULA.

Forty-six patients with end stage renal disease underwent forty-eight arteriovenous fistula formation by the Brescia-Cimino method between Jan 1994 and Jan 1997. The purpose of the fistula in all cases was to provide angioaccess for haemodialysis through the arterialised veins. Thirty-five (72.
