Colonoscopic polypectomy. North Indian experience.

Colonoscopic snare polypectomy was carried out in 70 patients (40 children, 30 adults). There was a male preponderance in both the groups with a combined male: female ratio of 4.4:1. The majority of patients (85%) were aged 20 years or below. All patients presented with intermittent bleeding per rectum, ranging from 2 months - 6 years (mean 1.2 +/- 1.1 years) in children and 1-14 years (1.9 +/- 2.3) in adults. The majority of patients polyps were located in the rectum (73%) or in the rectosigmoid region (21%). Polyps were significantly more common in the rectum (80% vs 63%; P less than 0.01) and less frequent in the rectosigmoid (15% vs 30%; p less than 0.01) in children as compared to adults. A single polyp was present in 49 (70%) patients; 17 (24%) had 2-10 polyps, while 4 patients (2 children, 2 adults) had more than ten polyps. Most patients (94%) had polyps of less than 2 cm size. Histologically, the most polyps (91.5%) were of the juvenile variety; 39 (97.5%) children and 25 (83%) adults had this variety of polyp. The remaining 5 (17%) adults and one (2.5%) child had adenomatous polyps. The difference in the polyp histology between the two age groups was statistically significant (p less than 0.05). Only one patient (1.4%) had excessive bleeding following polypectomy. The present study suggests two important differences in the nature of polyps as compared to the West: 1) our patients were much younger, and polyps were rare after 40 years; and (2) histologically, the commonest polyps were of the juvenile variety (91.5%) while adenomatous polyps were rare (8.5%).

Colorectal tuberculosis.

Seven cases of colorectal (five of colonic and two of rectal) tuberculosis are presented. Only one of these patients had associated pulmonary tuberculosis. Radiologic signs of colorectal tuberculosis are nontypical, making the preoperative diagnosis difficult. All five patients with colonic tuberculosis presented with subacute intestinal obstruction and underwent resectional surgery followed by antitubercular chemotherapy. Both patients with rectal tuberculosis presented with rectal strictures and were treated by repeated dilatation combined with antitubercular drugs. All seven patients have been followed for two to ten years and have remained asymptomatic.

Retained surgical sponge after laparotomy. Unusual presentation.

Erosion of a retained surgical sponge into the intestine is an unusual occurrence and may make its appearance months or years later. The demonstration of a distended bowel by the barium-impregnated mass with multiple polypoidal filling defects in a patient who has undergone previous laparotomy should lead the physician to suspect a retained surgical sponge. Surgical intervention is rewarding.
