        Background/Aims: Sclerotherapy with aluminum potassium sulfate and tannic acid (ALTA) has a potent effect on internalhemorrhoids. In this retrospective study, we compared the effects of endoscopic ALTA therapy and standard ALTA therapy. Methods: We investigated patients who underwent treatment for internal hemorrhoids at our institution between 2014 and 2016. Theywere divided into a standard ALTA group (n=33, treated using proctoscopy) and an endoscopic ALTA group (n=48). We compared theclinical findings between the 2 groups. Results: There were no intergroup differences in background factors. The mean ALTA dose was 21.9±7.2 mL and 17.8±3.4 mL inthe standard and endoscopic ALTA groups, respectively (p<0.01). Adverse events occurred in 4 patients (12.1%) from the standardALTA group and 6 patients (12.5%) from the endoscopic ALTA group. In both groups, the patients reported good satisfaction withthe therapeutic effect at 1 month after the procedure. Hemorrhoids recurred in 2 patients (6.3%) from the standard ALTA group and 4patients (8.3%) from the endoscopic ALTA group. Conclusions: Endoscopic ALTA sclerotherapy is equivalent to standard ALTA therapy in terms of efficacy, adverse events, andrecurrence. Therefore, it is a useful non-surgical option for patients with internal hemorrhoids who prefer a less invasive treatment.

        Phenotypic characteristics of pediatric inflammatory bowel disease in Japan: results from a multicenter registry

        ( Katsuhiro Arai ),( Reiko Kunisaki ),( Fumihiko Kakuta ),( Shin-ichiro Hagiwara ),( Takatsugu Murakoshi ),( Tadahiro Yanagi ),( Toshiaki Shimizu ),( Sawako Kato ),( Takashi Ishige ),( Tomoki Aomatsu 대한장연구학회 2020 Intestinal Research Vol.18 No.4

        Background/Aims: There are few published registry studies from Asia on pediatric inflammatory bowel disease (IBD). Registry network data enable comparisons among ethnic groups. This study examined the characteristics of IBD in Japanese children and compared them with those in European children. Methods: This was a cross-sectional multicenter registry study of newly diagnosed Japanese pediatric IBD patients. The Paris classification was used to categorize IBD features, and results were compared with published EUROKIDS data. Results: A total of 265 pediatric IBD patients were initially registered, with 22 later excluded for having incomplete demographic data. For the analysis, 91 Crohn’s disease (CD), 146 ulcerative colitis (UC), and 6 IBD-unclassified cases were eligible. For age at diagnosis, 20.9% of CD, 21.9% of UC, and 83.3% of IBD-unclassified cases were diagnosed before age 10 years. For CD location, 18.7%, 13.2%, 64.8%, 47.3%, and 20.9% were classified as involving L1 (ileocecum), L2 (colon), L3 (ileocolon), L4a (esophagus/stomach/duodenum), and L4b (jejunum/proximal ileum), respectively. For UC extent, 76% were classified as E4 (pancolitis). For CD behavior, B1 (non-stricturing/non-penetrating), B2 (stricturing), B3 (penetrating), and B2B3 were seen in 83.5%, 11.0%, 3.3%, and 2.2%, respectively. A comparison between Japanese and European children showed less L2 involvement (13.2% vs. 27.3%, P<0.01) but more L4a (47.3% vs. 29.6%, P<0.01) and L3 (64.8% vs. 52.7%, P<0.05) involvement in Japanese CD children. Pediatric perianal CD was more prevalent in Japanese children (34.1% vs. 9.7%, P<0.01). Conclusions: Upper gastrointestinal and perianal CD lesions are more common in Japanese children than in European children. (Intest Res 2020;18:412-420)
