Therapeutic gastrointestinal endoscopy.

ABSTRACT

The safety, efficacy and utility of various therapeutic gastrointestinal (GI) endoscopic procedures performed on children (January 1992 to July 1995) at a tertiary referral centre in India were studied. A total of 1,030 sessions (upper GI 972 and lower GI 58) of therapeutic GI endoscopy were performed in 162 children (mean age 7.4 +/- 4 years; upper GI 115, lower GI 47). Various upper GI endoscopic procedures done were injection sclerotherapy (EIS), endoscopic variceal ligation (EVL), bougie dilatation of oesophageal strictures, balloon dilatations of oesophageal stricture/pyloric obstruction and retrieval of foreign bodies in 75%, 6%, 9%, 4% and 12% of children respectively. Therapy for bleeding from oesophageal varices constituted the major group (75%). Repeated EIS (sessions total--876, mean 8, range 5-15) performed on 86 children resulted in control of bleeding in all and eradication of oesophageal varices in 85% of cases. Minor complications (oesophageal ulcers and oesophageal strictures) due to EIS were observed in 9% of children. EVL (10 sessions in 7 children) was effective in controlling bleeding and substantial decrease of varices in all without any complication. Oesophageal dilation either by bougie (61 sessions in 10 children) or balloon (6 sessions in 3 children) were performed for benign strictures. Balloon dilatation of pyloric obstruction was successfully done in 2 children. Foreign bodies (retained or sharp) were retrieved from upper GI tract in 14 children. No complications were observed with stricture dilatation/foreign body retrieval. Therapeutic lower GI endoscopies were performed in 47 children (colonoscopic polypectomy in 92%, anal dilatation and piles banding in 4% each). One child with juvenile polyposis coli developed sigmoid colon performation following colonoscopic polypectomy which required surgical correction. We conclude that upper and lower GI endoscopic therapeutic procedures in children are highly effective and safe. The risk of major complication is very small in experienced hands and occasional minor complications, can be managed conservatively.
