Gallbladder (GB) polyp is a mucosal projection into the GB lumen. With increasing health awareness, GB polyps are frequently found using ultrasonography during health screening. The prevalence of GB polyps ranges between 1.3% and 9.5%. Most patients are asymptomatic and have benign characteristics. Of the nonneoplastic polyps, cholesterol polyps are most common, accounting for 60%-70% of lesions. However, a few polyps have malignant potential. Currently, the guidelines recommend laparoscopic cholecystectomy for polyps larger than 1 cm in diameter due to their malignant potential. The treatment algorithm can be influenced by the size, shape, and numbers of polyps, old age (>50 years), the presence of primary sclerosing cholangitis, and gallstones. This review summarizes the commonly recognized concepts on GB polyps from diagnosis to an algorithm of treatment.

Background and Aim: Cholangiocarcinoma (CCA) is an uncommon malignancy of the bile duct, occurring in nearly 2 out of 100,000 people. It is a type of adenocarcinoma that originates in the mucous glands of the epithelium, or surface layers of the bile ducts. The aim of this study was to evaluate the clinical features, diagnostic results and factors associated with survival, morbidity and mortalityof cholangiocarcinoma cases in Iranian patients. Method: In this retrospective study the hospital medical records of 283 patients with a primary or final diagnosis of cholangiocarcinoma who had been admitted to gastroenterology ward of our hospital from 2004 to 2011 were retrospectively reviewed. Results: 283 patients (180 male, 63%, and 103 female, 38.6%) with a mean age of $59.7{\pm}14.4$ years were studied. The most frequent symptoms were painless jaundice (190, 66.9%), abdominal pain (77, 27%), pruritus 133 (46.8%) and weight loss (169, 59.5%). The most frequent associated risk factors and diseases were as follows: gallstones (72, 25.4%), diabetes (70, 24.6%), HBV infection (52 (18.3%), HCV infection 43 (15%), primary sclerosing cholangitis (16, 5.6%) and smoking (120, 42.3%). The most frequent type of cholangiocarcinoma in ERCP and MRCP was hilar. The mean survival time was $7.42{\pm}5.76$ months. Conclusion: The mean survival time in our study was lower than one year. Moreover the most frequent risk factors and associated diseases were smoking, gallstones and diabetes. Painless jaundice, abdominal pain and weight loss were the most clinical features related to cholangiocarcinoma. Additionally survival time did not correlate with risk factors, associated diseases and clinical presentations, but was linked to biliary metallic stenting and surgery.

Enterocytozoon bieneusi는 특히 AIDS환자에게 치명적인 질병을 초래하는 세균과 원충 중간단계의 병원체로서 현재 $30\~50\%$의 발생률오 AIDS환자로부터 가장 많이 발생되는 병원체로 알려져 있다. 하지만 이 병원체는 1980년 후반에서야 비로서 학계의 주목을 받기 시작했으며 환자에게 심한 만성설사, 기력 쇠진, 악성 영양 결핍 등을 주 임상증상으로 하고 있다. 이렇게 다양하고 심각한 질병을 일으킴에도 불구하고 현재까지 이 병원체에 대한 연구가 미흡하였다. 현재 이 병원체에 대한 가장 중요한 연구 중 연구 중 하나는 이 병원체에 대한 AIDS환자로의 전파 경로이다. 최근 여러 각도의 동물야외 조사 및 실험동물을 이용한 연구를 토대로 AIDS환자에 대한 이 병원체의 전파가능성은 감염동물에서부터 전파가 가장 중요한 경로가 될 거라 보고되고 있다.

Background: Patients with long-standing inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC). Colon cancer risk in IBD increases with longer duration and greater anatomic extent of colitis, the presence of primary sclerosing cholangitis, family history of CRC and degree of inflammation of the bowel. This study aimed to characterize the histopathological pattern of benign colorectal diseases among Saudi patients and to highlight age and gender variations of lesions as base line data for future studies to investigate the link between benign/IBD and colorectal cancers in the local population. Materials and Methods: The materials consisted of 684 biopsies, reported as benign (excluding malignancies and polyps) at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006 to December 2013. Data collected and entered in MS-Excel and were analyzed using SPSS-20. Results: Of 684 colorectal tissues reviewed, 408 specimens (59.6%) were from male patients and 276 specimens (40.4%) were from females giving a male: female ratio of 1.5:1. Age of the patients ranged from 4 to 75 years with a mean of 39.6 years. The most frequent histologic diagnosis was a chronic non specific proctocolitis followed by ulcerative colitis, accounting respectively for 52.6% and 31.7% of all cases. These were followed by Crohn's disease 22 (3.2%), ischemic bowel disease 20 (2.9%), diverticular disease 14 (2%), eosinophilic colitis 12 (1.7%) and solitary rectal ulcer 12 (1.7%). A minority of 21 patients (3.1%) were cases of acute nonspecific proctocolitis, schistosomiasis, tuberculosis, volvulus and pseudomembranous colitis. Conclusions: These data show that although chronic non specific proctocolitis and ulcerative colitis were the dominant diagnoses, Crohn's disease, ischemic bowel disease and diverticular disease also existed to a lesser extent and should be considered in the differential diagnosis of benign colorectal diseases. This study provides a base line data for future studies which would be taken up to investigate the link between benign/IBD and colorectal cancers in the local population.

Ulcerative colitis, an inflammatory bowel disease, is primarily managed medically with a combination of 5-ASA and steroids. However, this chronic disease requires surgical management if symptoms persist or complications develop despite medical management. The clinical course, indications and outcome of surgical management of 21 patients under the age of 15 who were endoscopically diagnosed with ulcerative colitis at the Seoul National University Children's Hospital between January, 1988 and January, 2003 were reviewed. Mean follow up period was 3 years and 10 months. The mean age was 10.3 years old. All patients received medical management after diagnosis and 8 patients (38 %) eventually required surgical management. Of 13 patients who received medical management only, 7 patients (53 %) showed remission, 4 patients are still on medical management, and 2 patients expired due to congenital immune deficiency and hepatic failure as a result of sclerosing cholangitis. In 8 patients who received surgical management, the indications for operation were, 1 patient sigmoid colon perforation and 7 patients intractability despite medical management. The perforated case had a segmental colon resection and the other 7 patients underwent total colectomy with ileal pouch-anal anastomosis. One patient expired postoperatively due to pneumonia and sepsis. and 1 is still on medical management because of mild persistent hematochezia after surgery. Six other operated patients are doing well without medical therapy. Pediatric ulcerative colitis patients can be surgically managed if the patient is intractable to medical management or if complications such as perforation are present. Total colectomy & ileal pouch-anal anastomosis is thought to be the adequate surgical method.

Backgrounds/Aims: Data regarding outcomes of endoscopic retrograde cholangiography (ERC) in liver transplant (LT) recipients with biliary-enteric (BE) anastomosis are limited. We report outcomes of ERC and percutaneous transhepatic biliary drainage (PTBD) as first-line therapies in LT recipients with BE anastomosis. Methods: All LT recipients with Roux-BE anastomosis from 2001 to 2020 were divided into ERC and PTBD subgroups. Technical success was defined as the ability to cannulate the bile duct. Clinical success was defined as the ability to perform cholangiography and therapeutic interventions. Results: A total of 36 LT recipients (25 males, age 53.5 ± 13 years) with Roux-BE anastomosis who underwent biliary intervention were identified. The most common indications for a BE anastomosis were primary sclerosing cholangitis (n = 14) and duct size mismatch (n = 10). Among the 29 patients who initially underwent ERC, technical success and clinical success were achieved in 24 (82.8%) and 22 (75.9%) patients, respectively. The initial endoscope used for the ERC was a single balloon enteroscope in 16 patients, a double balloon enteroscope in 7 patients, a pediatric colonoscope in 5 patients, and a conventional reusable duodenoscope in 1 patient. Among the 7 patients who underwent PTBD as the initial therapy, six (85.7%) achieved technical and clinical success (p = 0.57). Conclusions: In LT patients with Roux-BE anastomosis requiring biliary intervention, ERC with a balloon-assisted enteroscope is safe with a success rate comparable to PTBD. Both ERC and PTBD can be considered as first-line therapies for LT recipients with a BE anastomosis.

목 적: MRCP는 간담도췌장 질환을 진단하는데 있어서 비침습적인 방법으로 매우 유용한 것으로 알려져 있다. 본 연구의 목적은 간담도췌장 질환이 의심되는 소아에서 MRCP의 진단적 유용성에 대해 알아보고자 한다. 방 법: 1996년 10월부터 2001년 5월까지 연세의대 세브란스병원 소아과에 간담도췌장 질환으로 입원하여 복부 초음파 및 MRCP를 시행한 환아 70례를 대상으로 하였다. 환아의 최종 진단은 수술, 조직검사 소견, 임상 소견, 기타 검사 등을 토대로 하였다. 결 과 : 1) 대상 환아는 총 70례로 남녀비는 1 : 1.2였으며 평균 연령은 $2.6{\pm}3.3$세였다. 2) 간기능 검사상 혈청 AST, ALT 치는 각각 $192.7{\pm}139.6IU/L$, $182.7{\pm}143.8IU/L$이었고, 총 빌리루빈치, 직접 빌리루빈치는 각각 $6.9{\pm}3.7mg/dll$, $4.8{\pm}2.4mg/dll$이었다. 3) 간담도 췌장질환의 원인은 담도폐쇄증 25례(35.7%), 신생아 간염 18례(25.7%), 담관낭종 16례(23%)로 이 중 APBDU를 동반한 경우가 7례(10.0%), APBDU를 동반하지 않은 경우가 6례(12.9%)였으며, 전염성 단핵구증, 전격성 간염, 콕시엘라증(coxiellosis) 등으로 인한 담즙 정체성 간염이 5례(7.1%), 경화성 담도염이 2례(2.8%), 이차성 담도 경화증은 1례(1.4%), 만성 재발성 췌장염 환아가 3례(4.3%)였다. 4) 수술 소견과 병리 조직학적 소견을 기준으로 할 때 간담도췌장질환에 대한 복부 초음파의 진단의 정확도 75.7%에 비해 MRCP는 97.1%로 높았다. MRCP의 예민도와 특이도는 담도폐쇄증의 경우 각각 100%, 98%였고, APBDU가 동반된 담관낭종의 경우 87.5%, 100%였으며, APBDU가 동반되지 않은 담관낭종, 경화성 담도염, 만성 반복성췌장염은 양자 모두 100%였다. 결 론 : 본 연구에서 MRCP는 간담도췌장 질환을 진단하는데 있어서 편리하고 안전하며 비침습적인 방법으로서 그 진단율 또한 다른 검사에 비해 뛰어나 소아에서 간담도췌장질환이 의심될 때 우선적으로 시행할 수 있는 매우 유용한 검사임을 알 수 있었다.
