BACKGROUND/AIM: Colonoscopy has been known as the best diagnostic and therapeutic modality for colorectal polyps. However, it has been difficult to assess its accuracy. METHODS: We studied the data from patients who had colonoscopic polypectomy within 30 days after the initial examination. RESULTS: From 218 patients, a total of 362 polyps were found, 51 (14.1%) of which were missed. There were 17 patients with missed polyps among 59 patients who had two or more polyps on the initial examination. According to the location, the missing rates were variable: the splenic and hepatic flexure had the highest missing rates, and the sigmoid colon had the lowest missing rate. In our study, there was no difference of missing rate according to the size and shape. CONCLUSIONS: There is a significant colonoscopic missing rate for colorectal polyps in routine clinical practice, especially in patients with multiple colonic polyps and at the site of the colonic flexure.

BACKGROUND: Presently, a multidisciplinary team of doctors, pharmacists, nurses, and dietitians provides patient education to impart information on chemotherapy. However, studies on multidisciplinary education satisfaction are inadequate. In this study, we aimed to contribute to the improvement of quality of multidisciplinary education counseling for patients with cancer by developing a satisfaction questionnaire and analyzing the satisfaction survey. METHODS: A questionnaire was developed by an expert group, and the responses were recorded using the 5-point Likert scale. After conducting a pre-test, factor analysis was performed to evaluate validity. The reliability of the questionnaire was measured by Cronbach's alpha coefficient. A satisfaction survey was conducted by self-administration method. RESULTS: Based on the results of factor analysis, factors can be divided into two parts: “overall education” and “each team member's education” (total 14 questions). The construct validity and reliability of the questionnaire are sufficiently high. Fifty-one patients took the survey between January 2, 2018 and January 20, 2018. Twenty-six (51%) patients responded that they were “very satisfied” and 22 (43.1%) patients responded that they were “satisfied”. CONCLUSION: By developing a questionnaire on multidisciplinary education counseling for patients with cancer, it is possible to perform evaluation and research of cancer patient education. This study will contribute to the management and improvement of quality of multidisciplinary education.

Background: Probiotics are live microorganisms that confer health benefits on the host. Many animal studies have shown that among the probiotics, lactobacilli exert favorable effects on bone metabolism. Herein, we report the results of a randomized controlled trial performed to investigate the effect of Lactobacillus fermentum (L. fermentum) SRK414 on bone health in postmenopausal women. Methods: The bone turnover markers (BTMs) and bone mineral density (BMD) in participants in the study group (N=27; mean age, 58.4±3.4 years) and control group (N=26; mean age, 59.5±3.4 years) were compared during a 6-month trial. BTMs were measured at pretrial, 3 months post-trial, and 6 months post-trial, while BMD was measured at pre-trial and 6 months post-trial. Changes in the gut microorganisms were also evaluated. Results: Femur neck BMD showed a significant increase at 6 months post-trial in the study group (P=0.030) but not in the control group. The control group showed a decrease in osteocalcin (OC) levels (P=0.028), whereas the levels in the study group were maintained during the trial period. The change in L. fermentum concentration was significantly correlated with that in OC levels (r=0.386, P=0.047) in the study group at 3 months post-trial. Conclusions Probiotic (L. fermentum SRK414) supplementation was found to maintain OC levels and increase femur neck BMD during a 6-month trial in postmenopausal women. Further studies with a larger number of participants and a longer study period are required to increase the utility of probiotics as an alternative to osteoporosis medication.

PURPOSE: No standardized treatment protocol yet exists for intestinal Behcet's disease. The aim of this retrospective study was to identify the factors that are related to the recurrence and mortality of intestinal Behcet's disease. METHODS: Twelve patients who had undergone surgery for intestinal Behcet's disease at Korea University Hospital from 1991 to 1999 were chosen. Nineteen patients had been diagnosed as having intestinal Behcet's disease. Of the 19 patients, 7 are still being followed up, and 12 have undergone surgery, these patients were chosen as the subjects. RESULTS: Of the 11 cases, excluding one case that expired following the initial surgery, 8 cases required subsequent surgery due to recurrence. When the data was analyzed according to the patient's age, medication, classification of Behcet's disease, location of the lesion, operative method, and extent of resection, recurrence was shown to be related with medication and extent of resection (p<0.05). Of the 12 cases, 5 cases expired. When, the data of the 5 cases that expired were analyzed according to the patient's age, medication, extent of resection, classification of Behcet's disease, location of the lesion, and operative method, mortality was shown to be related with the location of the lesion (p<0.05). CONCLUSION: Medical treatment is the primary therapy for intestinal Behcet's disease and radical extended resection extending 30 cm proximal and distal to the lesion prevents recurrence. However, when the lesion was located in the small intestine and formed a fistula with the duodenum, the prognosis appears to be extremely poor.

PURPOSE: Splenic artery aneurysm is uncommon, but the increased frequency in use of arteriography, computed tomography, and ultrasonography has resulted in increasing clinical recognition of these lesions. This paper relates our experience in the outcome and management of aneurysms of the splenic artery. METHODS: From January 1992 to October 1999, 12 patients were diagnosed with splenic artery aneurysms. They were retrospectively analyzed. RESULTS: The male to female ratio was 1:4 and the mean age was 46.3 years. The mean of pregnancy history of all women was 3.0 and there were no pregnant women during operation. The associated diseases that might have caused the aneurysms were pancreatitis in 5 patients, portal hypertension in 1, operative trauma in 1, and ill defined pathogenesis in 5 patients. The size of the aneurysms was larger than 2 cm in all patients. The splenic artery aneurysms was located at distal in 9 patients, mid in 1, and proximal in 2 patients. 7 patients were treated surgically (aneurysmectomy without splenectomy in 1 patient, aneurysmectomy with splenectomy in 6 patients). Transcatheter embolization was used in 4 patients. One of them was treated with distal pancreatectomy after two months because of pancreatic pseudocyst. One patient without treatment died 2 years after diagnosis. CONCLUSION: Although surgery remains necessary in splenic artery aneurysms larger than 2 cm, transcatheter embolization is effective in initial treatment of the high risk group in splenic artery aneurysms.

PURPOSE: By virtue of advances in scientific methods and technical systems, there has been a rapid growth in the number of end stage renal disease (ESRD) patients treated using continuous ambulatory peritoneal dialysis (CAPD) as their primary renal replacement therapy. However, there are various catheter related complications that are limiting factors in patient and catheter maintenance. This study was aimed at introducing of the techniques of CAPD catheter implantation designed for reducing the complication rate, as well as conducting an investigation of the incidence of CAPD catheter related complications and patient survival and catheter survival rates. METHODS: We performed 234 cases of CAPD catheter implantation using a conventional surgical method (n=162, between January 1993 and December 1997) or a modified surgical method (n=72, between January 1998 and December 1999), and retrospectively reviewed the patient's medical records to elucidate the incidence of early catheter related complications and the catheter removal rate in relation to the surgical methods. RESULTS: There were 21 cases (23.8%) of peritonitis in the modified group, which was less than that in the conventional group (79 cases, 48.8%) (P=0.036). There were 9 cases (12.5%) of exit site and tunnel infection in the modified group, which was less than that in the conventional group (36 cases, 22.2%) (P=0.019). We were able to reduce the peritonitis as well as exit site and tunnel infection by a long segment of tunneling and immobilization of the catheter to the skin. Nine cases of leakage (5.5%) have occurred in the conventional group and one case (1.3%) in the modified group; the difference was statistically significant (P=0.046). CONCLUSION: These results indicate that our modified surgical methods can reduce the rate of early catheter related complications.
