This paper compares the positive predictive value of an immunochemical fecal occult blood test for colorectal neoplasms between the stool specimens obtained during the digital rectal examination and those obtained during the routine screening. ⋯ These findings indicate that the stool obtained by routine screening has a better positive predictive value than stool collected during the digital rectal examination.

Clinical Trial
Abdominosacral resection for primary irresectable and locally recurrent rectal cancer.
The purpose of this study was to present a technique of abdominosacral resection and its results in patients with locally advanced primary or locally recurrent rectal cancer with dorsolateral fixation. ⋯ The abdominosacral resection provides wide access and may be the therapeutic solution for the accomplishment of a radical resection for distally situated, dorsally or dorsolaterally fixed primary or locally recurrent rectal cancers.

Case Reports
Experience with radiofrequency ablation in the treatment of pelvic recurrence in rectal cancer: report of two cases.
The aim of this study was to assess the efficacy of radiofrequency ablation in the treatment of pelvic recurrent rectal cancer. ⋯ Radiofrequency ablation is a relatively readily maneuverable and safe local treatment for pelvic recurrence in rectal cancer and is considered a procedure worth applying with further accumulation of experience in clinical cases.

Randomized Controlled Trial Clinical Trial
The WAND local anesthetic delivery system: a more pleasant experience for anal anesthesia.
The WAND is a computer-controlled local anesthetic delivery system. Its use has been proven to be more comfortable for dental patients. The purpose of this study is to explore its applicability to anal procedures. Our hypothesis is that the WAND will provide greater comfort during anesthesia delivery while achieving the same anesthetic effect as traditional syringe technique. ⋯ The WAND is as effective as the traditional syringe technique in the delivery of anal anesthesia while providing a more comfortable experience for the patient.

Comparative Study Clinical Trial
Primary vs. secondary anastomosis after sigmoid colon resection for perforated diverticulitis (Hinchey Stage III and IV): a prospective outcome and cost analysis.
Our hypothesis was that in patients with perforated sigmoid colon diverticulitis and peritonitis (Hinchey Stage III and IV) a one-stage sigmoid colon resection is safe and cost effective when performed by an experienced colorectal surgeon. We evaluated outcome and cost of one-stage vs. two-stage sigmoid colon resection after diverticulitis perforation and peritonitis. ⋯ With meticulous surgical technique and extensive intraoperative lavage, perforated sigmoid colon diverticulitis with peritonitis can be treated by a one-stage sigmoid colon resection and anastomosis with a low mortality and morbidity. A one-stage procedure is considerably cheaper and patients are rehabilitated faster and to a higher percentage.
