Gastrointestinal visceral motor complications of dermatomal herpes zoster: report of two cases and review

Abstract

Motor complications are uncommon manifestations of herpes zoster. This report describes two cases of gastrointestinal visceral motor manifestations associated with dermatomal herpes zoster and reviews the English-language literature since 1900. The 17 cases reviewed were divided clinically into two groups: colonic pseudo-obstruction and localized colonic spasm. Characteristics of the patients, radiographic study results, endoscopic findings, proposed pathogenesis, and management options are discussed. It is important to recognize this manifestation in order to institute proper management and avoid unnecessary surgery, given the complete resolution with conservative management in most cases.
