Department of Gastroenterology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Background And Aims: Although the incidence of inflammatory bowel disease (IBD) is increasing in Asia, data on long-term epidemiologic trends are limited. We performed a 30-year longitudinal study to investigate temporal trends in the epidemiology of Crohn's disease (CD) and ulcerative colitis (UC) in Seoul, Korea.

Methods: This population-based study included 1431 IBD patients (418 CD, 1013 UC) diagnosed between 1986 and 2015 in the Songpa-Kangdong district of Seoul, Korea. Read More

Purpose Of Review: Endoscopic ultrasound (EUS) is routinely utilized for evaluation of disorders of the lower gastrointestinal tract. In this review, we summarize the current status of rectal EUS in clinical practice and describe recent developments in diagnostic and therapeutic rectal EUS.

Recent Findings: Recent guidelines recommend rectal EUS for rectal cancer staging as a second line modality in cases where MRI is contraindicated. Read More

Hyperimmunoglobulinaemia D syndrome is an autoinflammatory disease usually representing recurrent episodes of fever, arthralgia/arthritis, cervical lymphadenopathy, vomiting, diarrhoea, abdominal pain and skin rashes lasting 3-7 days every 4-8 weeks since their infancy. Recent reports suggested a link between perianal fistulae/abscess and severe colitis with hyperimmunoglobulinaemia D syndrome resembling an inflammatory bowel disease phenotype. Herein, we report an 18-month-old patient with recurrent attacks of fever and pharyngitis lasting 2-3 days every 10-15 days since the first two weeks of life. Read More

Internal Medicine, Florida Hospital, Orlando, USA.

Liver abscess is a rare complication seen in Crohn's disease (CD) and has been rarely reported. Our aim is to illustrate a case of liver abscess in a patient with CD and the importance of a complete history and physical examination in identifying the potential cause of a hepatic abscess in an immune competent individual in who the diagnosis of CD was apparently ignored for two years before she presented to us. Although the manifestation of a hepatic abscess without any perianal abscess or fistula in CD is extremely rare, recognition of this would facilitate the diagnosis and appropriate management of abscess and CD.

Background: Treatment of anorectal abscesses continues to revolve around early surgical drainage and control of perianal sepsis. Yet even with prompt drainage, abscess recurrence and postoperative fistula formation rates are as high as 40% within 12 months. These complications are thought to be associated with inadequate drainage, elevated bacterial load, or a noncryptoglandular etiology of disease. Read More

Crohn disease (CD) is a chronic inflammatory disease involving the entire digestive tract and non-perianal fistula is the most serious surgical complication of CD. The goal of treatment is to cure intestinal fistula and intra-abdominal infection, restore the continuity of digestive tract, reduce postoperative recurrence, and improve the quality of life. Evaluation of nutritional status, especially during perioperative period, is important and nutrition support for malnutritional CD patients is necessary. Read More

Many disorders of the digestive tract cause cutaneous manifestations that may be an indication of an underlying condition; hence dermatologist plays a key role in recommending that the patient see a gastroenterologist. Conversely, gastroenterologist often sees patients with mucocutaneous lesions suggesting possible association with well-known digestive disorders. Chronic inflammatory bowel diseases are the typical example of this essential collaboration between the two specialities. Read More

Department of Radiology, Hacettepe University School of Medicine, Ankara, Turkey.

Purpose: Anal fistula is an abnormal tract or cavity between the anal canal and perianal skin. Surgical treatment of anal fistulas requires the identification of the course of the primary and secondary tracts and their relation with the sphincter musculature in order to appropriately manage them and drain any abscess. Physical examination alone is not as accurate as imaging modalities in detecting these features of the fistula, and recurrences are usually due to missed or inadequately managed infective components.

Hidradenitis suppurativa (HS), also known as Verneuil's disease and acne inversa, is a chronic inflammatory skin disease characterized by a dysfunction of the pilosebaceous structures resulting in occlusion and inflammation. The disease usually starts after puberty, on average between twenty and thirty years, with subcutaneous painful inflammatory nodules, abscess collections, fistulization and scars mainly in the axillary, inguinal, sub-mammary, perineal and perianal regions. It is a multifactorial disease with the most commonly cited risk factors or aggravating factors being smoking, obesity, and HS family history. Read More
