[Pediatric colonoscopic polypectomy].
Colorectal polyps are relatively frequent in infancy and constitute one of the main causes of bleeding per rectum. Endoscopic polypectomy, with its lower morbidity and mortality, has revolutionized its treatment. Between October 1, 1985 and May 31, 1994, 122 polypectomies were done in 88 pediatric patients. Forty five patients (51.1%) were male and 43 female (48.9%). Forty four patients (50%) were between 1 and 5 years of age. Ninety five polyps (77.9%) were found more frequently in the rectum. Regarding the size, 63 polyps (51.6%) measured between 1 and 2 cm. Seventy three patients (83%) had a single polyp, 10 patients (11.4%) had 2 polyps and 1 patient had 12 polyps. Ninety six polyps (78.7%) were pedunculated, being this the more frequent form found. Histologically the most common was the juvenile polyp, found in 106 cases (87.6%). The polypectomies was carried out without using general anesthesia and is performed as an outpatient procedure. We had no experience of endoscopic complications. It is concluded that colonoscopy polypectomy is a useful, simple and safe procedure for treating colorectal polyps in children.

[Cholelithiasis in patients with liver cirrhosis].
We retrospectively studied 67 cirrhotic patients hospitalized in the service of gastroenterology of Hospital Daniel A. Carrión, Callao, Perú, between June 1993 and July 1995, aimed to determine the frequency of cholelithiasis and its main clinical and epidemiological features. Twelve out of 67 cirrhotic patients (17.91%) had cholelithiasis. 24% of women and 14.3% of men were affected (p > 0.05). The mean age of women and men were 57.33 and 57.5 years old respectively (range: 41-67 years old). The frequency of cholelithiasis did not increase with age and the proportionally most affected age group was 41-50 years (33.33%). Alcoholic etiology was the most often in cirrhotic patients with cholelithiasis (41.67%). The severity of liver disease influenced in the cholelithiasis frequency (p = 0.001) and 33.33% of patients with gallstones were in grade C of Child Pugh Score. Two thirds of patients were asymptomatic. We conclude: 1. Cholelithiasis in our cirrhotic patients more prevalent than in general population (17.91% vs 0.7-5%). 2. Age did not influence in cholelithiasis prevalence in our cirrhotic patients. 3. The severity of liver disfunction influenced in highly significant way (p = 0.001) on cholelithiasis prevalence. 4. Cirrhotic patients with gallstones had mostly (66.67%) an asymptomatic course.
