Low diagnostic sensitivity of cystoscopy and cystography of surgically confirmed vesicoenteric fistulae.

Purpose: The objective of this study was to assess the accuracy of cystoscopy and cystography, as compared to other diagnostic studies, in identifying vesicoenteric fistulae (VEF) in a contemporary series of patients with surgically confirmed VEF.

Methods: With institutional review board approval, we performed a single-center retrospective review of surgically confirmed VEF between 2002 and 2018. Demographic data, comorbidities, symptoms, and diagnostic evaluation were reviewed.

No clinical benefit from routine histologic examination of stapler doughnuts at low anterior resection for rectal cancer.

Background: The aim of this study was to evaluate the clinical utility and cost-effectiveness of routine histologic examination of the doughnuts from stapled anastomoses in patients undergoing a low anterior resection for rectal cancer.

Methods: We performed a retrospective review of 486 patients who underwent a low anterior resection with stapled anastomosis for rectal cancer between 2002 and 2015 at 3 institutions. Pathologic findings in the doughnuts and their impact on patient management were recorded.

Management of low colorectal anastomotic leak: Preserving the anastomosis.

Anastomotic leak continues to be a dreaded complication after colorectal surgery, especially in the low colorectal or coloanal anastomosis. However, there has been no consensus on the management of the low colorectal anastomotic leak. Currently operative procedures are reserved for patients with frank purulent or feculent peritonitis and unstable vital signs, and vary from simple fecal diversion with drainage to resection of the anastomosis and closure of the rectal stump with end colostomy (Hartmann's procedure).

Anal Adenocarcinoma: Outcomes in an Uncommon Malignancy.

Adenocarcinoma is an uncommon malignancy of the anal canal. Although it is recognized as an aggressive disease, optimal management and long-term outcomes are not well established. Patients diagnosed with anal adenocarcinoma were identified from a cancer database.

Excess of proximal microsatellite-stable colorectal cancer in African Americans from a multiethnic study.

Purpose: African Americans (AA) have the highest incidence of colorectal cancer compared with other U.S. populations and more proximal colorectal cancers.

Management of anastomotic leak: lessons learned from a large colon and rectal surgery training program.

Background: Anastomotic leak is a dreaded surgical complication that can lead to significant morbidity and mortality. Despite its prevalence, there is no consensus on the management of anastomotic leak. This study aimed to review the management of anastomotic leak in the Division of Colon and Rectal Surgery at two institutions.

Causative pathogens, antibiotic sensitivity, resistance patterns, and severity in a contemporary series of Fournier's gangrene.

Objective: To identify the causative pathogens and evaluate the antibiotic sensitivity, resistance patterns, and virulence in a contemporary series of patients with Fournier's gangrene.

Materials And Methods: The medical records of 41 consecutive cases of Fournier's gangrene were evaluated. The patient demographics, causative pathogens, antibiotic sensitivity, and resistance patterns were assessed.

A comparison of open and robotic total mesorectal excision for rectal adenocarcinoma.

Purpose: This retrospective study was designed to compare open with robot-assisted total mesorectal excision for rectal adenocarcinoma.

Methods: With use of predefined exclusion criteria, all consecutive laparoscopic-assisted (51 patients) and robot-assisted (36 patients) rectal resections for adenocarcinoma from August 2005 to November 2009 at a single institution were considered. Hand-assisted laparoscopy was used for splenic flexure mobilization in all cases.

Total mesorectal excision for rectal cancer: the potential advantage of robotic assistance.

Purpose: The purpose of this study was to analyze the safety, feasibility, and efficacy of the da Vinci S HD robotic system in mesorectal excision for rectal adenocarcinoma, with the aim to identify areas of potential advantage for the robot in this procedure.

Methods: This study was conducted as a retrospective review of a prospectively maintained database of 44 consecutive cases of robot-assisted mesorectal excision for rectal adenocarcinoma performed between August 2005 and February 2010. Patient demographics, perioperative outcomes, and complications were evaluated and compared with similar published reports and relevant literature.

Robotic assistance in right hemicolectomy: is there a role?

Purpose: The purpose of this study was to evaluate the results, postoperative outcomes, and cost of robotic assistance in right hemicolectomy and determine its safety, feasibility, and efficacy as compared with the conventional laparoscopic approach.

Methods: From August 2005 to February 2009, 40 robot-assisted right hemicolectomies were performed by the authors at a single institution. These were compared with 135 laparoscopic right hemicolectomies performed by the authors, at the same hospital and during the same time period.

Epidermoid cancers of the anal canal: current treatment.

Epidermoid carcinoma of the anal canal is an uncommon disease, but has increased in incidence with the HIV epidemic. Prior to the 1970s, treatment consisted of radical surgery with abdominoperineal resection. With the pioneering work of Dr.

The Parkland formula under fire: is the criticism justified?

Controversy has continued regarding the practicality and accuracy of the Parkland burn formula since its introduction over 35 years ago. The best guide for adequacy of resuscitation is urine output (UOP) per hour. A retrospective study of patients resuscitated with the Parkland formula was conducted to determine the accuracy (calculated vs.

Surgical site infections after colorectal surgery: do risk factors vary depending on the type of infection considered?

Background: The purpose of this study was to compare risk factors for the development of incisional versus organ/space infections in patients undergoing colorectal surgery.

Methods: An institutional review board-approved retrospective review was performed examining a 4-year period (January 2002 to December 2005). Patients were included if they had undergone abdominal operations (open or laparoscopic) in which the colon/rectum was surgically manipulated.
