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

The natural history of Crohn's disease (CD) is characterized by a remitting and relapsing course and a considerable number of patients ultimately require bowel resection. Moreover, postoperative recurrence is very common. Relatively few studies have investigated the postoperative recurrence of CD in Korea. The aim of the current study was to assess postoperative recurrence rates - both clinical and endoscopic - in CD as well as factors influencing postoperative recurrence.

Methods

Electronic medical records of patients who underwent surgery due to CD were reviewed and analyzed. Patients with incomplete surgical resection, a follow-up period of less than a year, and a history of strictureplasty or perianal surgery were excluded.

Results

Of 112 CD patients, 39 patients had history of bowel resection, and 34 patients met the inclusion criteria. Among them, 26 were male (76%) and the mean age of onset was 32.8 years. The mean follow-up period after operation was 65.4 months. Cumulative clinical recurrence rates were 8.8%, 12.5%, and 33.5% at 12, 24, and 48 months, respectively. Use of immunomodulators for prophylaxis was the only predictor of clinical recurrence in univariate analysis (P=0.042). Of 21 patients who had undergone follow-up colonoscopy after surgery, cumulative endoscopic recurrence rates were 33.3%, 42.9%, and 66.1% at 6, 12, and 24 months, respectively. No significant predicting factor for endoscopic recurrence was detected.

Conclusions

Postoperative recurrence rates in Korean patients with CD are high, and endoscopic recurrence rates are comparable to those reported from Western studies. Appropriate medical prophylaxis seems to be important for preventing postoperative recurrence in CD.

The Inflamed Appendiceal Orifice does not Always Suggest Acute Appendicitis

AbstractAbstract PDF
Background/Aims
Colonoscopy may be helpful in the diagnosis of appendicitis occasionally. However, it is unclear that isolated inflammation at the appendiceal orifice is always suggestive of acute appendicitis. Methods: Eighteen consecutive patients with colonoscopic findings of the isolated inflammatory lesion in the area of the appendiceal orifice were included. Surgical- pathology-proven appendicitis within 6 months after the colonoscopy were defined as 'true-appendicitis'. Results: Of the 18 patients, 16 patients were followed up for more than 6 months. Seven patients underwent appendectomy within 5-79 days after the colonoscopy. Of these, 4 patients (25%) had true-appendicitis, one periappendiceal abscess without appendicitis, two normal appendices. Nine patients did not take appendectomy. Of these, no definite etiology was defined in 6. Of the rest, one patient revealed Crohn's disease, one Behcet's disease and one cecal involvement of distal ulcerative colitis later. Conclusions: Isolated inflammation at the appendiceal orifice does not always suggest acute appendicitis but diverse etiologies. The diagnosis of appendicitis should not be made only by colonoscopic findings but also by clinical course and other imaging studies. (Intestinal Research 2006;4:39-44)

Case Reports

AbstractAbstract PDF
Arteriovenous malformation is well known cause of lower gastrointestinal bleeding in elderly patients. This is relatively uncommon in people younger than 50 years of age. Endoscopically, it generally appears as bright red flat or elevated bright red lesion. A polypoid appearance is extremely uncommon. We report a case of large polypoid arteriovenous malformation of colon in 81-year-old male patient. He has complained of hematochezia for 4 days. During colonoscopy, a 3.5 cm sized semipedunculated polypoid mass in the proximal transverse colon was detected. For prevention of bleeding, detachable snare was applied and biopsy was done. 3 days later, follow up colonoscopy was done. There was no hemorrhege. We performed endoscopic mucosal resection. Polypoid arteriovenous malformation of colon was comfirmed by microscopic findings. Histologically, section of excised polyp shows ulceration, hemorrhage and the dilated, irregularly thick walled blood vessels in the mucosa and submucosa. (Intestinal Research 2004;2:36-39)

AbstractAbstract PDF
Recently, we experienced a case of bacterial overgrowth syndrome with recurrent edema, hypoproteinemia and normal serum cobalamine level after Billoth II subtotal gastrectomy, which was diagnosed by jejunal aspirates culture and antibiotics treatment. When predisposition and clinical suspicion were present, jejunal culture might be preferable especially in case of post-Billoth II operation status because jejunal approach is easy, screening tests are negative in certain cases and some screening tests are not available in Korea.
