Endoscopic Nd:YAG laser treatment of severe radiation injury of the lower gastrointestinal tract: long-term follow-up.

We report a series of patients with severe radiation injury treated with endoscopic laser photocoagulation. Eight patients with recurrent lower gastrointestinal bleeding secondary to procosigmoiditis were treated with endoscopic Nd:YAG laser therapy. Patients were followed for an average of 21.7 months after the first laser treatment. Average transfusion requirements and hospital admissions per patient-month were 0.93 and 0.27, respectively, in the prelaser period and 0.18 and 0.06, respectively, in the entire period following the first laser treatment. A total of 26 laser treatments were performed. There were three major (prolonged ileus) and one minor (pain) complication. We conclude that endoscopic Nd:YAG laser photocoagulation is a safe, effective, and lasting treatment in severe, symptomatic radiation injury of the lower gastrointestinal tract.

CT diagnosis of dorsal pancreas agenesis.

We report a case of agenesis of dorsal pancreas diagnosed by CT. This anomaly can easily be confused with pancreas divisum on endoscopic retrograde cholangiopancreatography alone.

Diagnosis of swine dysentery: spirochaetes which may be confused with Treponema hyodysenteriae.

Spirochaetes, designated PWS, microscopically resembling Treponema hyodysenteriae, were isolated from the colon contents of pigs with post-weaning scours from three herds, which on clinical and epidemiological grounds were thought to be free from swine dysentery. One of the isolates was fed to pigs experimentally but no evidence of disease was noted. Their cultural characteristics differed from those of T hyodysenteriae but they were similar to those of a non-pathogenic spirachaete (4/71) which had been isolated previously from the laboratory's dysentery-free herd. Smears prepared from cultures of the PWS spirochaete, 4/71 and two virulent and one avirulent strain of T hyodysenteriae were all positive to a fluorescent antibody test which was in use as an aid to the diagnosis of swine dysentery in the United Kingdom.
