Stage IV Colorectal Cancer at Initial Presentation versus Progression during and after Treatment, Differences in Management: Management Differences for Initial Presentation versus Progression of Disease after Initial Treatment.

Stage IV colorectal cancer is a prevalent disease and understanding the appropriate treatment options is important. Medical oncologic treatment remains the mainstay of treatment in cases where curative resection is not possible. Surgical intervention is indicated if the primary tumor and associated metastases are amenable to curative resection or if obstructive, bleeding, or perforative complications arise from the tumor.

Seasonal and Geographic Variation in Peptic Ulcer Disease and Associated Complications in the United States of America.

Background: Hospitalization for peptic ulcer disease (PUD) has been described outside of North America as peaking in the fall and winter. However, no recent literature has so far investigated the seasonal fluctuations and complications of PUD in the USA. Cross-sectional population database review.

Seasonal Variations and Factors that Influence Diverticular Bleeding in the United States of America.

Background: Seasonal variation in hospitalizations for diverticulitis has a sinusoidal pattern, peaking in summer. Little is known about seasonal, regional trends, and risk factors associated with hospital admissions regarding diverticular bleeding in the United States.

Study Design: Cross-sectional population database review using the healthcare cost and utilization project's national inpatient sample.

Trends in General Surgery Resident Experience with Colorectal Surgery: An Analysis of the Accreditation Council for Graduate Medical Education Case Logs.

Objective: Colorectal surgery is a core component of general surgery. The volume of colorectal surgery performed by general surgery residents throughout training has not been studied. This study aims to analyze trends observed in colorectal-specific case numbers logged by general surgery residents over 16 years.

Use of Preoperative Laboratory Testing Among Low-Risk Patients Undergoing Elective Anorectal Surgery.

Background: Many low-risk patients receive preoperative laboratory testing (PLT) prior to elective outpatient surgery, with no effect on postoperative outcomes. This has not been studied in patients undergoing anorectal surgery. The aim of this study was to determine if PLT in this population was predictive of perioperative complications.

An update on surgical treatment of hemorrhoidal disease: a systematic review and meta-analysis.

Background: Pathologic hemorrhoids are common among adults age 45-65. Hemorrhoids are characterized as internal or external, and grades 1-4 based on severity. The type and grade dictate treatment, with surgical treatment reserved for grades 3/4.

HIV-positive women with anal high-grade squamous intraepithelial lesions: a study of 153 cases with long-term anogenital surveillance.

Women living with HIV (WLHIV) are at increased risk for human papillomavirus (HPV)-associated anal cancer. Given the "field effect" of HPV pathogenesis, some recommend that anal cancer screening should be limited to WLHIV with prior genital disease. This study aimed to characterize the relationship between anal and genital disease in WLHIV in order to better inform anal cancer screening guidelines.

An Update on the Current Role of High Resolution Anoscopy in Patients With Anal Dysplasia.

The incidence of anal squamous cell carcinoma (ASCC) in the U.S. is increasing, particularly in immunocompromised patients.

Morbidity and Mortality Risk Assessment in Gynecologic Oncology Surgery Using the American College of Surgeons National Surgical Quality Improvement Program Database.

Introduction: Gynecologic oncology patients represent a distinct patient population with a variety of surgical risks. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database provides an opportunity to analyze large cohorts of patients over extended periods with high accuracy. Our goal was to develop a postoperative risk assessment calculator capable of providing a standardized, objective means of preoperatively identifying high-risk patients in the gynecologic oncology population.

Perioperative strategies to prevent surgical-site infection.

Colon and rectal resections are among the most common surgical procedures performed in the United States. Complication rates of up to 25% have been reported and result in a substantial impact on quality of life and cost of care. Recently, the Surgical Care Improvement Program (SCIP) has promoted guidelines to prevent postoperative and potentially preventable complications.

Premalignant lesions of the anal canal and squamous cell carcinoma of the anal canal.

Squamous cell carcinoma of the anus (SCCA) is a rare tumor. However, its incidence has been increasing in men and women over the past 25 years worldwide. Risk factors associated with this cancer are those behaviors that predispose individuals to human papillomavirus (HPV) infection and immunosuppression.
