Intestinal tuberculosis is a common disease of extrapulmonary tuberculosis and should be differentiated from the inflammatory bowel diseases and malignancy such as Crohn's disease, ulcerative colitis, amebic colitis, and colon cancer. Most frequently involved sites (75% of cases) are the terminal ileum and cecum. Other sites of involvement, in order of frequency, are ascending colon, jejunum, appendix, duodenum, stomach, esophagus, sigmoid colon, and rectum. Intestinal tuberculosis simultaneously involving the stomach and colon has been very rarely reported. Recently, we experienced a case of synchronous gastric and colonic ulcers with granulomatous inflammation. Although we did not find acid fast bacilli and the culture test was negative, empirical anti-tuberculosis therapy resulted in dramatic clinical and endoscopic improvement. We report a rare case of multifocal gastrointestinal tuberculosis with a review of literature.

Patients with inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC). Accordingly, the duration and anatomic extent of the disease have been known to affect the development of IBD-related CRC. When CRC occurs in patients with IBD, unlike in sporadic CRC, it is difficult to detect the lesions because of mucosal changes caused by inflammation. In addition, the tumor types vary with ill-circumscribed lesions, and the cancer is difficult to diagnose and remedy at an early stage. For the diagnosis of CRC in patients with IBD, screening endoscopy is recommended 8 to 10 years after the IBD diagnosis, and surveillance colonoscopy is recommended every 1 to 2 years thereafter. The recent development of targeted biopsies using chromoendoscopy and relatively newer endoscopic techniques helps in the early diagnosis of CRC in patients with IBD. A total proctocolectomy is advisable when high-grade dysplasia or multifocal low-grade dysplasia is confirmed by screening endoscopy or surveillance colonoscopy or if a nonadenoma-like dysplasia-associated lesion or mass is detected. Currently, pharmacotherapies are being extensively studied as a way to prevent IBD-related CRC.

Most common cause of brisk hematochezia is diverticular bleeding in Western countries. It occurs in 15% of patients with diverticulosis and one-third of them appear to be massive. Most of diverticulosis in Western countries occur in the left colon but the right colon is more common in Korea. Especially, the reports of diverticular bleeding on left colon are rare in Korea. We report a case presenting with multiple diverticuli complicated by recurrent massive bleeding restricted to the left colon. 75-year-old female was admitted due to hematochezia and dizziness. On past history, two years and two weeks ago respectively, she was treated of diverticular bleeding with and without diverticulitis. Hemoglobin level was 9.8 g/dL. On Colonoscopy, numerous diverticuli were seen at sigmoid colon upto splenic flexure which showed fresh blood clots in the lumen. We diagnosed her as recurrent massive diverticular bleeding on the sigmoid colon. She received elective laparoscopic left hemicolectomy.

Self-expandable stents are widely available for the treatment of perforation of the gastrointestinal tract. Because of the risk of migration, there has been no report of the use of self-expandable stents for the treatment of perforation of the colon or rectum. This is a report of successful treatment of iatrogenic colonic perforation during balloon dilatation of anastomotic stricture with a fully covered stent. Fully covered, self-expandable metallic stents can be considered useful tools for management of this condition.

A 68-year-old woman with known severe aortic stenosis was admitted to the hospital because of hematochezia and dizziness. She had received several blood transfusions over the preceding 3 years and undergone right hemicolectomy 2 years ago for severe lower gastrointestinal bleeding. Postoperative histology revealed angiodysplasia involving the ascending colon. After the hemicolectomy, she continued to have hematochezia and anemia and required additional blood transfusions for anemia. During this admission, platelet count, activated partial-thromboplastin time, von Willebrand factor antigen, and von Willebrand factor ristocetin cofactor were normal. She had a severe deficiency of high-molecular-weight multimers of von Willebrand factor. Colonoscopy showed angiodysplasia in the transverse colon at this time. Successful coagulation of the bleeding angiodysplasia was achieved by argon plasma coagulator. No additional bleeding was observed thereafter. We report a case of Heyde's syndrome with abnormal von Willebrand factor in a patient who presented with intestinal angiodysplasia and aortic stenosis.

Pneumatosis cystoides intestinalis (PCI) is a rare condition defined as the presence of multiple gas-filled cysts in the wall of gastrointestinal tract. The etiology and pathogenesis of PCI remain uncertain. It is associated with various medicosurgical conditions, including various pulmonary and gastointestinal diseases, connective tissue diseases and endoscopic procedures. The diagnosis is confirmed by endoscopic puncture and biopsy. PCI in adults, for the most part, show a benign clinical course and better prognosis if the associated disease is well controlled. Infantile PCI is more serious condition and especially associated with necrotizing enteritis. The treatment is usually conservative, However surgical intervention is needed when complications such as intussusception, obstruction, bleeding and perforation develope. We experienced a case of PCI found during the follow-up colonoscopy in a patient taken right hemicolectomy and systemic adjuvant chemotherapy due to colon cancer.

Lower gastrointestinal complications often develop in end stage renal disease patients, and among the more problematic is recurrent colon ulcer. The exact pathogenesis of this condition is not known and there were no specific therapeutic modalities concerning this type of disease entity. We report, with a literature review, a case of recurrent colon ulcer with intermittent hematochezia in an end stage renal disease patient on long term hemodialysis that improved after conversion to peritoneal dialysis.

We experienced a rare case of colonic cryptococcosis in an apparently immunocompetent individual. A 27-year- old woman admitted our hospital for intermittent melena. Initial abdominal CT scan revealed a mass lesion obstructing most of the lumen in ascending colon. Colonoscopy showed huge ulcerofungating mass in proximal ascending colon. Colonoscopic biopsy was performed and pathologic diagnosis was made as colonic cryptococcosis with positive PAS stain. Laboratory test evaluating immune status and bone marrow examination was normal. The patient was treated with intravenous amphotericin B for four weeks and six months of oral fluconazole afterwards. Follow-up abdominal CT scan and colonoscopy were taken at four weeks and seven months after the beginning of treatment. On completion of intravenous amphotericin B treatment, the mass lesion was decreased in abdominal CT and colonoscopy. After seven months, abdominal CT and colonoscopy showed near-complete resolution of the colonic lesion so the treatment ended. Cryptococcosis in a healthy individual is a rare disease and there have been only several sporadic case reports on pulmonary or central nervous system involvement. Hence, we report a case of colonic cryptococcosis in an apparently immunocompetent individual.
