Analysis of clinical, imaging and endoscopic characteristics of 14 patients with idiopathic mesenteric phlebosclerosis / 中华消化杂志

ABSTRACT

Objective:To investigate the clinical, imaging and endoscopic characteristics of idiopathic mesenteric phlebosclerosis (IMP).Methods:From January 2010 to December 2020, 14 patients with IMP diagnosed and treated at the Quzhou Hospital Affiliated to Wenzhou Medical University (Quzhou People′s Hospital) were enrolled. All patients underwent abdominal X-ray, contrast enhanced computed tomography (CT) and endoscopy. Three cases accepted double-contrast barium enema and 11 cases underwent endoscopic biopsy. Three of the 14 IMP patients underwent surgery and pathological examination because of intestinal perforation or intestinal obstruction that failed conservative treatment. The general data (such as gender, drinking history, etc.), clinical symptoms, complications, imaging (abdominal X-ray, CT, double-contrast barium enema) and endoscopic features were retrospectively analyzed. Descriptive method was used for statistical analysis.Results:Among the 14 IMP patients, 13 cases were male and one case was female. All the 13 male cases had long history of drinking Chinese herbal medicine wine, among them, 8 patients consumed acanthopanax bark wine. Complications occurred in 7 cases, including 5 cases of intestinal obstruction and 2 cases of intestinal perforation. The clinical symptoms of 14 IMP patients were nonspecific, mostly manifested as abdominal pain (11 cases), abdominal distension (6 cases), diarrhea (6 cases), nausea and vomiting (4 cases), and constipation (2 cases). Abdominal X-ray images mainly showed multiple irregular calcifications along involved colon. The images of 3 patients received double-contrast barium enema demonstrated shallowness or disappearance of semilunar folds, rigid colonic wall, narrowed lumen and " thumb printing". The typical CT images indicated edema and thickening of the involved intestinal wall, blurred mesenteric fat space, spot, thread-like, and curved calcification of mesenteric vein and colonic wall. Typical endoscopic findings included dark-purple colored mucosa, congestion, edema, erosion and ulceration, and focal nodular surface and visible varicose veins.Conclusions:IMP has typical imaging and endoscopic characteristics, and the combination of them can diagnose and evaluate IMP more accurately.
