      Prominent publications by Walter E Longo

      KOL-Index: 16088

      INTRODUCTION: Previous research has demonstrated that nonsteroidal anti-inflammatory agents alter the incidence of colorectal cancer. It has been postulated that the response may be due to the effect of these agents on the activities of the cyclooxygenase (COX) enzymes. The COX enzymes catalyze the conversion of arachidonic acid to biologically active prostanoids. Two forms of COX have been identified. COX-1 is a constitutive enzyme, generally involved in cell functions, while COX-2 is ...

      OBJECTIVE: Opioid abuse has become an epidemic in the United States, causing nearly 50,000 deaths a year. Postoperative pain is an unavoidable consequence of most surgery, and surgeons must balance the need for sufficient analgesia with the risks of overprescribing. Prescribing narcotics is often the responsibility of surgical residents, yet little is known about their opioid-prescribing habits, influences, and training experience.

      DESIGN: Anonymous online survey that assessed the ...

      BACKGROUND: Although family and lifestyle are known to be important factors for medical students choosing a specialty, there is a lack of research about general surgery residency program policies regarding pregnancy and parenthood. Similarly, little is known about program director attitudes about these issues.

      STUDY DESIGN: We performed a cross-sectional survey of United States (US) general surgery residency program directors.

      RESULTS: Sixty-six respondents completed the survey: 70% ...

      PURPOSE: In various studies, type of surgery, age, and gender had different impact on sexuality and quality of life in patients with rectal cancer. This study was designed to investigate how sexuality and quality of life are affected by age, gender, and type of surgery.

      METHODS: A total of 516 patients who had undergone surgery for rectal cancer in our department from 1992 to 2002 were included. Within one year after the operation, 117 patients died. Questionnaires were sent to 373 ...

      OBJECTIVE: The outcomes of patients with squamous cell carcinoma of the anal canal treated by either sphincter-preserving procedures or radical surgery were evaluated, with the goals of identifying factors predicting treatment failure and quantifying results of salvage therapy in patients with recurrent disease.

      BASIC PROCEDURES: A population-based study on all patients in all 159 hospitals of the Department of Veterans Affairs (VA) from 1987 to 1991 was carried out. Data were compiled ...

      PURPOSE: Comorbid conditions affect the risk of adverse outcomes after surgery, but the magnitude of risk has not previously been quantified using multivariate statistical methods and prospectively collected data. Identifying factors that predict results of surgical procedures would be valuable in assessing the quality of surgical care. This study was performed to define risk factors that predict adverse events after colectomy for cancer in Department of Veterans Affairs Medical ...

      To determine how quality of life changes over time and to assess gender-related differences in quality of life of rectal cancer patients we conducted a 5-year study. Little is known about how quality of life (QoL) changes over time in patients after surgery for rectal cancer, and whether gender of the patients is associated with a different perception of QoL. The aim of this study was to assess prospectively, changes in quality of life after surgery for rectal cancer, with a focus on ...

      BACKGROUND: General surgical training has changed significantly over the last decade with work hour restrictions, increasing subspecialization, the expanding use of minimally invasive techniques, and nonoperative management for solid organ trauma. Given these changes, this study was undertaken to assess the confidence of graduating general surgery residents in performing open surgical operations and to determine factors associated with increased confidence.

      METHODS: A survey was ...

      OBJECTIVE: To define risk factors that predict adverse outcomes after the surgical treatment of appendicitis in Department of Veterans Affairs Medical Centers.

      SUMMARY BACKGROUND DATA: Risk factors for adverse outcomes after the surgical treatment of appendicitis in adults are poorly defined. Accurate presurgical assessment of the risk of perioperative complications and death is important in planning surgical therapy.

      METHODS: The VA National Surgical Quality Improvement Program contains ...

      HYPOTHESIS: We hypothesized that the model for end-stage liver disease (MELD) score may be a better and less subjective method than the Child-Turcotte-Pugh score for stratifying patients with cirrhosis before abdominal surgery.

      DESIGN: Retrospective medical record review.

      SETTING: Tertiary care institution.

      PATIENTS: Fifty-three adult patients with histologically proven cirrhosis undergoing abdominal surgery at Saint Louis University Hospital, St Louis, Mo, between 1991 and 2001. Those ...

      OBJECTIVE: To identify rapidly modifiable risk factors that would improve surgical outcomes in elderly patients undergoing emergent colorectal procedures who are at high risk for morbidity and mortality.

      DESIGN: Retrospective review. Patients were identified on the basis of Current Procedural Terminology codes and admission through the emergency department. Medical records were reviewed and data were abstracted for comorbidities, procedural details, and in-hospital morbidity and ...

      OBJECTIVES: Patients with spinal cord injury (SCI) and chronic indwelling catheters are known to be at increased risk of bladder malignancy. "Decatheterization" by clean intermittent catheterization, external condom catheterization, or spontaneous voiding is thought to reduce the risk by decreasing the chronic mucosal irritation and rate of infection. We examined two Department of Veterans Affairs (DVA) data bases to test this theory.

      METHODS: A population-based retrospective analysis of ...

      Peptide YY (PYY) and enteroglucagon are hormonal peptides found in endocrine cells of the distal intestinal mucosa. Although it is known that plasma concentrations of both peptides increase in response to feeding, the mechanism by which ingested food causes release of colonic hormones is not understood. The release of PYY and enteroglucagon was measured in response to intraluminal stimuli in 176 patients having investigative colonoscopy. Introduction of air, saline (isotonic and ...

      KOL-Index: 10372

      BACKGROUND: Primary repair has become the most common method of treatment for civilian injuries of the colon. However, colostomy may still be required in selected patients.

      AIMS: This study was undertaken to identify factors for the performance of colostomy in patients with colon injuries.

      METHODS: During a 60-month period, all penetrating injuries to the colon treated at Saint Louis University Hospital were evaluated. All patients underwent an operation within six hours of injury. ...

      OBJECTIVE: To define risk factors that predict adverse outcomes after proctectomy for cancer in Department of Veterans Affairs Medical Centers.

      SUMMARY BACKGROUND DATA: Accurate presurgical assessment of the risk of perioperative complications and death is important in planning surgical therapy.

      METHODS: The National VA Surgical Quality Improvement Program contains prospectively collected and extensively validated data on >287,000 patients. All patients undergoing proctectomy for rectal ...
