<b>Background/Aims</b><br/>

Crohn's disease (CD) is a chronic inflammatory bowel disease that presents with variable features and repeated disease aggravation. The incidence of CD is increasing in Korea. We evaluated the clinical features of CD in a study population in Busan and Gyeongnam, Korea.

Methods

A hospital-based analysis included 619 patients diagnosed with CD between March 1986 and February 2013 from seven tertiary care hospitals in Busan and Gyeongnam. Individual case records were reviewed with regard to age at diagnosis, sex, disease location, disease behavior, and medical and surgical treatments received during the follow-up period.

Results

The cumulative frequency of patients diagnosed with CD revealed a continued increase in the number of cases reported yearly. The male-to-female ratio was 2.5:1 and the median age at diagnosis was 24 years. At diagnosis, 114 (18.4%) had isolated small bowel disease, 144 (23.3%) had isolated colonic disease, and 358 patients (57.8%) presented with disease in the small bowel and colon. The number of patients presenting with stricturing or penetrating disease behavior was 291 (47%) at the final evaluation. In total, 111 (17.9%) patients underwent intestinal resections.

Conclusions

A continued increase in the number of patients diagnosed with CD was found in Busan and Gyeongnam as observed in other regions. We report results similar to that of other Korean studies in terms of sex distribution, age, and location of disease.

Clinical and Endoscopic Characteristics of Acute Hemorrhagic Rectal Ulcer and the Risk Factor of Rebleeding
Sung Han Park, Tae Oh Kim, Jung Nam Lee, Hyun Seok You, Dong Yup Ryu, Bong Yun Lee, Geun Am Song
Intest Res 2009;7(1):8-13.   Published online June 30, 2009
AbstractAbstract PDF
Background/Aims
Acute hemorrhagic rectal ulcers (AHRUs) are rare and have not been thoroughly studied. This study aimed to assess the clinical and endoscopic characteristics of AHRUs and to determine the risk factors for rebleeding after the initial management. Methods: Thirty patients who underwent colonoscopy within 48 hours of the onset of hematochezia were consecutively enrolled between January 2004 and December 2007. The patients were divided into a rebleeding group and a non-rebleeding group according to presence of recurrent bleeding after initial management. We analyzed the clinical features, including the underlying disorder, the Karnofsky performance status (PS), the use of anticoagulant or antiplatelet agents, the endoscopic findings, and the methods used for hemostasis. Results: All of the patients were elderly, in a bedridden status, and all had experienced the sudden onset of massive, fresh rectal bleeding without pain. The characteristics of the lesions on colonoscopy included solitary or multiple rectal ulcers, or Dieulafoy lesions located in the distal rectum. There were no differences between the two groups based on mean age, gender, use of anticoagulant or antiplatelet agents, PS, methods of hemostasis, and clinical outcomes. The PT (INR) and endoscopic findings (Dieulafoy types), however, differed significantly between the two groups (p=0.024 and p=0.013, respectively). Conclusions: When massive hematochezia occurs in bedridden patients with severe comorbid illnesses, AHRUs should be considered in the differential diagnosis. It is advisable to be vigilant for rebleeding in patients with prolongation of the PT (INR) and Dieulafoy-type ulcers on colonoscopy.

Case Report
A Case of Acute Lower Gastrointestinal Bleeding from Appendix
Sun Mi Lee, Tae Oh Kim, Gwang Ha Kim, Jung Heo, Dae Hwan Kang, Geun Am Song, Mong Cho
Intest Res 2007;5(2):184-187.   Published online December 30, 2007
AbstractAbstract PDF
It is known that the most common causes of lower gastrointestinal bleeding are diverticulosis and angiodysplasia. In addition to these causes, a malignant neoplasm, hemorrhoids, Meckel’s diverticulum, infection, Crohn’s disease, inflammatory disease due to radiation treatment, ischemic colitis, and vasculitis due to connective tissue disease can commonly produce lower gastrointestinal bleeding. A colon varix, endometriosis, or Dieulafoy's lesion rarely causes lower gastrointestinal bleeding. Lower gastrointestinal bleeding that is localized to the appendix is extremely rare, and may be caused by angiodysplasia, an ulcer due to aspirin, endometriosis, a lymphoma, or fissures on the mucous membrane associated with appendicitis. A colonoscopy, radioisotope scan, and angiography are modalities used to diagnose lower gastrointestinal bleeding, and recently, multi-detector row CT (MDCT) has been used for cases where it has been difficult to locate a lesion with other methods or to diagnose a patient when endoscopic access was not available. We report a case of a patient that came to the hospital complaining of hematochezia, and bleeding in the appendix was determined after an MDCT examination and colonoscopy. Subsequently, the patient was treated with surgery. (Intest Res 2007;5:184-187)

Clinicopathologic Features and Endoscopic Treatment of Laterally Spreading Tumors of the Colorectum
Cheol Woong Choi, Sun Mi Lee, Tae Oh Kim, Gwang Ha Kim, Jung Heo, Dae Hwan Kang, Geun Am Song, Mong Cho
Intest Res 2007;5(1):33-37.   Published online June 30, 2007
AbstractAbstract PDF
Background/Aims
Laterally spreading tumors (LSTs) of the colorectum are defined as lesions greater than 10 mm in diameter with a low vertical axis that extend laterally along the luminal wall. We analyzed the clinicopathologic characteristics and endoscopic treatment of LSTs on the colorectum. Methods: The 127 colorectal LSTs were collected from January 2005 through February 2007. Those lesions were analysed according to their endoscopic and pathologic findings. Results: 67 LSTs (52.8%) were more than 20 mm in size. Most common involved sites of LSTs were rectum (32.4%) and ascending colon (25.9%). Most common subtype of LSTs were granular-homogeneous type (G-H) (37%). Histologic types were 76 tubular adenomas (59.8%), 24 tubulovillous adenomas (18.8%), 6 villous adenomas (4.8%) and 21 adenocarcinoma (16.6%). Both nodular mixed type (G-NM) and pseudo-depressed type (NG-PD) contained a carcinomatous component with high frequency as compared with the G-H type. Carcinoma invaded into the submucosa were present in 3 lesions of G-NM type and 6 lesions of NG-PD type. Conclusions: LSTs showed different clinicopathologic characteristics depending on the morphologic classification. G-NM type or NG-PD type had more malignant potential than other types. Endoscopists should select an adequate therapeutic strategy for large LST with careful consideration. (Intest Res 2007;5:33-37)

Rare Diseases of Rectum and Sigmoid Colon
Geun Am Song
Intest Res 2006;4(1):1-6.   Published online June 30, 2006
AbstractAbstract PDF
The rectum is approximately 10 to 15 cm in length and extends from the sigmoid colon to the anal canal. It contribute to defecation as the rectal walls expand, stretch receptors from the nervous system located in the rectal walls stimulate the desire to defecate. There are some differences between rectum and colon. The rectum is divided into two portion by peritoneal reflection and makes pouch. The pouch is associated with many pathologic conditions, such as rectal shelf in stomach cancer, rectal endometriosis, and spread of pelvic inflammation. The inferior mesenteric arteries and middle, inferior rectal arteries supply the rectum. This dual blood supply system causes different incidence of ischemic inserts and metastatic site in rectum and colon cancer. The function of anal sphincter and rectum in pelvic cavity is significantly important in defecation and its disturbance causes some specific rectal disease. Due to its position, rectum may be injuried by external and internal events and show the initial suggestion of colorectal disease. We describe uncommon specific diseases in rectum classified into inflammatory diseases, functional disease and tumor. (Intestinal Research 2006;4:1-6)
