Experience with a cholinesterase histochemical technique for rectal suction biopsies in the diagnosis of Hirschsprung's disease.

Cryostat sections from 160 rectal suction biopsies were stained for cholinesterases by the method of Karnovsky and Roots (1964) in an attempt to facilitate the diagnosis of Hirschsprung's disease. The method proved at least as reliable as experienced assessment of paraffin haematoxylin-eosin sections, and appeared to offer the advantages of reduced scanning fatigue and superior demonstration of the increased cholinesterase-positive nerves in Hirschprung's disease. Contrary to the findings of Meier-Ruge (1971) it was not possible to base a diagnosis on mucosal cholinesterase activity.

Management of ingested foreign bodies in childhood.

A total of 660 patients with ingested foreign bodies admitted to the general surgical services in two children's hospitals in Liverpool are reviewed. Endoscopic removal (205 cases) is recommended for all foreign objects impacted in the oesophagus, with the exception of rounded or blunt objects in the lower third, which should be observed for a maximum of 12 hours. The indications for laparotomy for removal of a foreign body (43 cases, 6.5%) are the danger of perforation and failure of progression. The ingestion of a long slender object-for example a hair-grip-in a child under 2 years of age, is an absolute indication for prophylactic operative removal owing to the high incidence of impaction and perforation of the duodenum.
