Current screening guidelines overlook a significant number of patients treated for colorectal cancer.

The U.S. Preventive Services Task Force (USPSTF) recommends screening for colorectal cancer (CRC) in adults, beginning at age 50 years and continuing until age 75 years.

The efficacy and morbidity of different surgical treatment techniques for chronic anal fissure: an academic colorectal experience.

Up to 40 per cent of chronic fissures will fail to heal with medical treatment alone. Open (OLIS) and closed (CLIS) lateral internal sphincterotomies are considered by many to be the treatment of choice for chronic anal fissures (CAF). The aim of this study was to compare the efficacy and clinical outcomes of different surgical techniques for treatment of CAF.

Differential lymph node retrieval in rectal cancer: associated factors and effect on survival.

Background: Recent publications have identified positive associations between numbers of lymph nodes pathologically examined and five-year overall survival (5-yr OS) in colon cancer. However, focused examinations of relationships between survival of rectal cancer and lymph node counts are less common. We conducted a single institution, retrospective review of rectal cancer resections to determine whether lymph node counts correlated with 5-yr OS and to explore the relationship between lymph node counts and various clinical and pathologic factors.

Neuroendocrine tumors of the rectum: a 10-year review of management.

Neuroendocrine tumors of the rectum constitute approximately 19 per cent of gastrointestinal neuroendocrine tumors (NETs). The histologic characteristics of the tumor seem to be an indicative prognostic factor. Optimal treatment of NETS of the rectum has been widely debated, but more recent studies suggest that treatment depends upon the size.
