Systematic Analysis for Factors Associated with Symptomatic Mesenteric Phlebosclerosis in Japanese / 日本東洋医学雑誌

Growing evidences indicate that the development of mesenteric phlebosclerosis (MP) is associated with long-­term gardenia fruit (GF) intake. Besides duration and total dosage of GF ingestion, other factors associated with the development of MP or the symptoms of MP have not been known. We searched for previous case reports of MP from Japan. MP patients were divided into two groups : asymptomatic group without abdominal symptoms or symptomatic group. Age, gender ratio, body size, and duration of GF ingestion of the both groups were statistically analyzed. We evaluated concomitant diseases that can cause elevated venous pressure in the both groups. Colectomy rate were compared between symptomatic men and symptomatic women. Severe symptoms including ileus, stenosis peritonitis, and perforation were also compared between men and women. Age and sex were analyzed in all 164 cases. The gender ratio of women to men in the symptomatic group was higher than that in the asymptomatic group. However, colectomy rate in the symptomatic group was similar between men and women. Ileus, stenosis, peritonitis, and perforation were similarly found in both men and women. We found 15 symptomatic MP patients with concomitant diseases that can cause phlebostasis. None of the asymptomatic had these diseases. Concomitant diseases that can cause elevated venous pressure might be associated with symptomatic MP. The severity of MP seems to be similar between men and women. Association of gender difference with the development of MP symptoms was uncertain.

<b>Screening for Idiopathic Mesenteric Phlebosclerosis in Outpatients Undergoing Long-Term Treatment at the Department of Kampo Medicine</b> / 日本東洋医学雑誌

<p>Idiopathic mesenteric phlebosclerosis (IMP) is a rare chronic ischemic intestinal disease, mainly in the right hemicolon, characterized by dark purple mucosa on colonoscopy and calcifications of the intestinal wall and mesenteric veins on abdominal radiography and computed tomography. In recent years, many patients who developed IMP over the long-term administration of Kampo medicines have been reported. However, the present status of IMP in patients under long-term treatment with Kampo medicines in departments specializing in Kampo therapy is unclear. We surveyed whether there were any IMP outpatients followed for 5 years or more at the Department of Oriental Traditional Medical Center, Suwa Central Hospital. We detected 2 of 257 (0.8%) patients having IMP. Both patients had undergone long-term treatment with Gardenia fruit. One of them underwent surgery due to acute abdomen, but the other was asymptomatic. The etiology and pathogenesis of IMP are still unclear. However, in patients undergoing long-term treatment with Kampo medicines, particularly containing Gardenia fruit, the possible presence of IMP should be taken into consideration, and active screening using imaging examinations is necessary even in asymptomatic patients.</p>
