Colonoscopic polypectomy and long-term prevention of colorectal-cancer deaths.

Background: In the National Polyp Study (NPS), colorectal cancer was prevented by colonoscopic removal of adenomatous polyps. We evaluated the long-term effect of colonoscopic polypectomy in a study on mortality from colorectal cancer.

Methods: We included in this analysis all patients prospectively referred for initial colonoscopy (between 1980 and 1990) at NPS clinical centers who had polyps (adenomas and nonadenomas).

Selective use of esophageal manometry and 24-Hour pH monitoring before laparoscopic fundoplication.

Background: Preoperative esophageal manometry and 24-hour pH monitoring commonly are used in preoperative evaluation of patients undergoing fundoplication. Here we review our experience with the selective preoperative workup of patients undergoing fundoplication to treat gastroesophageal reflux disease.

Study Design: A series of 628 consecutive antireflux procedures was reviewed.

Case report: "Popcorn" dystrophic ileal calcification in a patient with Crohn's disease.

Small bowel calcification is a rare finding, often associated with chronic infection or small intestinal neoplasms. The authors report a patient who developed dystrophic ileal calcification in the setting of medically refractory Crohn's disease. The patient had longstanding, obstructive ileal Crohn's disease, treated with corticosteroids for a 10-year period.
