title: [Digestive involvement in progressive systemic sclerosis].
abstract: We studied 14 patients with PSS, 12 females and 2 males with a mean age of 43.6 and a medium of 8 years disease. All of the patients were selected for this study according to updated ARA criteria and were included in a prospective protocol to investigate digestive involvement. This protocol consists of a complete medical history, physical examination, radiologic and endoscopic studies, parasitological and microbial flora investigation. The symptoms more frequently seen were: pyrosis (78%), gastroesophageal regurgitation (50%), flatulence (50%), dysphagia (42%) and chronic diarrhea (21%). The radiologic findings commonly seen were: distal esophageal aperistalsis (78%), gastroesophageal reflux (57%), dilatation of intestinal loops (35%), changes of the mucosal folds (35%). A mild esophagitis was seen endoscopically in 64% of the patients, moderate and severe in 7% respectively. The study of the microbial flora showed contaminations with enterobacteria in 5 patients (35%). After statistical analysis we concluded that the digestive compromise by PSS is frequent, being the esophagus more commonly affected (80%), at the beginning in the form of reflux esophagitis and later in esophageal stenosis, the compromise of the small intestine (40%) is manifested by chronic diarrhea or dyspeptic flatulence, which correlates well the radiologic findings and the bacterial overgrowth in this organ. The colonic compromise generally is asymptomatic, and the common finding is dilatation os the colonic loops. Finally, the bacterial overgrowth in the small intestine is a secondary involvement to the intestinal compromise of Progressive Systemic Sclerosis.
