Considerable disagreement exists regarding whether endometrial polyps should be removed before attempting natural pregnancy and before pregnancy via intrauterine insemination (IUI) or in vitro fertilization (IVF). Through a literature review, we obtained information on the impact of endometrial polyps and polypectomy on fertility outcomes. Several observational studies have suggested that women with unexplained infertility may benefit from endometrial polypectomy for a future natural pregnancy. A few studies reported benefits from endometrial polypectomy in infertile women who plan to undergo IUI. However, no strong evidence supports polypectomy as a way to improve the pregnancy rate in infertile women who plan to undergo IVF or polypectomy during controlled ovarian stimulation for IVF. Although no studies have defined criteria for the polyp size that should be removed in infertile women, clinicians should be aware that small endometrial polyps (<10 mm) sometimes regress spontaneously. Endometrial polypectomy is currently justified in patients with repeated IVF failure, but more studies are needed to verify that endometrial polypectomy itself will eventually increase the pregnancy rate. Although several mechanisms by which endometrial polyps exert a negative effect on fertility have emerged, there is no consensus about the proper management of endometrial polyps in infertile women. Therefore, the management of endometrial polyps should be individualized depending on the patient's situation and clinician's preference.

Background: This study investigates the influence factors of medical service variations using medical charge and the length of stay (LOS) for urinary incontinence surgery and uterine polypectomy. Methods: The National Health Insurance claims data and Medical Resource Report by the Health Insurance Review & Assessment Service in 2016 were used. Frequency analysis, one-way analysis of variance, and Bonferroni post-hoc tests were executed for each surgery. A multilevel analysis was executed to assess the factors to the medical charge and LOS for each surgery in patient, doctor, and hospital level. Results: Fifty-two point eight percent of urinary incontinence surgery and 87.1% of uterine polypectomy were distributed in general and tertiary hospitals. Among three levels, the patient level variation was 61.5% or 77.2% in medical charge and 93.9% or 96.3% in LOS, respectively. The doctor level variation was 29.6% or 22.6% in medical charge and 0.6% or 0.0% in LOS, respectively. The institution level variation was 8.9% or 0.2% in medical charge and 5.5% or 3.7% in LOS, respectively. Number of other disease and organizational type were main factors that affected the charge and LOS for urinary incontinence surgery and uterine polypectomy. Conclusion: Medical service variations of the urinary incontinence surgery and uterine polypectomy were the largest for the patient level, followed by doctor level for the medical charge, and the institution level for the LOS.

This study was performed to determine the effect of patients with colon polypectomy on health behavior practices. Data were surveyed using interview and questionnaires by 112 patients with colon polypectomy in a general hospital who were located in Seoul from December 6, 2010 to January 31, 2011. Data were evaluated with t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression. The results were as follows: First, the higher control of life habit was, the more positive attitude(r=.350, p<.01) and the less inconvenience was significant correlation(r=-.263, p<.05). Secondly, in the stepwise multiple regression analysis, the most important factors influencing health behavior practices were control of life habit(${\beta}$=.392, p=.000), and then inconvenience of life(${\beta}$=-.265, p=.007), weight gain(${\beta}$=-.248, p=.024). In conclusion, positive attitude and control of life habit are necessary to improve the health behavior of patient with colon polypectomy.

In patients having long-standing ulcerative colitis (UC), the risk of colorectal cancer (CRC) increased compared with general population. Dysplasia is a precancerous lesion of colitic patients, and traditionally total proctocolectomy was considered as a standard therapy to prevent colorectal cancer in UC patients. However, even with ileal pouch-anal anastomosis (IPAA), patients who underwent total proctocolectomy may experience early and late postoperative complications, such as ileus, bleeding, pouchitis, and so on. In addition, the bowel movement after proctocolectomy with IPAA reaches a median of seven times per day, and a considerable proportion of patients require daytime and nighttime pads. Change in the strategy for managing dysplasia started from two early studies, which suggested polypectomy for polypoid dysplasia to prevent CRC in colitic patients. After that, many studies supported that polypectomy should be the first option for the management of polypoid dysplasia. Moreover, recent studies suggested the feasibility of endoscopic submucosal dissection as a therapeutic option for non-polypoid dysplasia, although long term, large studies should be followed.

Purpose : This study was performed to know the clinical profile and effectiveness of colonoscopic polypectomy in patients with solitary juvenile polyp. Methods : This study included 19 children, aged 1.8 to 11.4 years, who underwent colonoscopic polypectomy and histologically proven solitary juvenile polyps between March 1998 and August 2002. We analyzed their detailed history, clinical manifestations, colonoscopic examination, method of anesthesia and results of colonoscopic polypectomy. Results : The mean age of the 19 cases was $4.7{\pm}2.8year$. The male to female ratio was 1 : 1.1. Hematochezia, the main indication of colonoscopy, was present in all cases. Combined symptoms were mucoid stool or diarrhea(42%), abdominal pain(26%), constipation(11%) and anal fissure(11%). Anemia(Hb <10 g/dL) in four cases recovered spontaneously after polypectomy. Complications associated with premedication, sedation and colonoscopy itself did not occur. Bleeding developed in two cases(11%) after polypectomy. One of them was controlled with hemoclipping. The main site of polyps was the rectosigmoid colon in 15 cases(79%). The size of the polyps ranged from 0.5 to 3.5 cm. The interval between the onset of symptoms and polypectomy was from 0.1 to 42 months. Conclusion : Juvenile polyps are a common cause of benign, chronic and recurrent rectal bleeding. Colonoscopic polypectomy is a simple, safe and effective therapeutic method. So earlier colonoscopy might avoid uneffective treatment and prevent untoward problems such as fear of parents and anemia.

Purpose: Colonoscopy is considered the most reliable method for the diagnosis of juvenile polyps. However, colonoscopic screening is an invasive and expensive procedure. Fecal calprotectin (FCP), a marker of intestinal inflammation, has been shown to be elevated in patients with polyps. Therefore, this study aimed to evaluate FCP as a screening biomarker for the diagnosis of juvenile polyps. Methods: This cross-sectional, observational study was conducted at the Pediatric Gastroenterology and Nutrition Department, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. For children with polyps, colonoscopic polypectomy and histopathology were performed. FCP levels were analyzed before and 4 weeks after polypectomy in all patients. Information was recorded in a datasheet and analyzed using the computer-based program SPSS. Results: The age of the children was between 2.5 and 12 years. Approximately 93% of the polyps were found in the rectosigmoid region. Children with juvenile polyps had elevated levels of FCP before polypectomy that subsequently normalized after polypectomy. The mean FCP levels before and after polypectomy were 277±247 ㎍/g (range, 80-1,000 ㎍/g) and 48.57±38.23 ㎍/g (range, 29-140 ㎍/g) (p<0.001), respectively. The FCP levels were significantly higher in patients with multiple polyps than in those with single polyps. Moreover, mean FCP levels in patients with single and multiple polyps were 207.6±172.4 ㎍/g and 515.4±320.5 ㎍/g (p<0.001), respectively. Conclusion: Colonic juvenile polyps were found to be associated with elevated levels of FCP that normalized after polypectomy. Therefore, FCP may be recommended as a noninvasive screening biomarker for diagnosis of colonic juvenile polyps.

Purpose: Total colonoscopy is recommended if colorectal polyps are clinically suspected. This study aimed to investigate the performance status of pediatric colonoscopic polypectomy in Korea. Methods: We surveyed pediatric endoscopic specialists who perform colonoscopic polypectomy in Korea using a questionnaire of 13 questions on pediatric colonoscopic polypectomy performance status. Results: The survey was conducted at 45 institutions, and 32 specialists (71.1%) responded. Among the respondents, 31.2% (10/32) said colonoscopy was performed in all age groups, while 12.5% (4/32) said sigmoidoscopy was performed in all age groups. Meanwhile, 56.2% (18/32) said that sigmoidoscopy was performed in young children, while colonoscopy was performed in older children. Among them, 38.9% (7/18) believe that 4-6 years were young, and 44.5% (8/18) believe that 7-9 years were young. Regarding surveillance examinations, 21.9% (7/32) said they would perform a surveillance colonoscopy or sigmoidoscopy in the future if less than five juvenile polyps were found in the colon. Meanwhile, if less than five adenomatous polyps were found in the colon, 93.8% (30/32) said they would perform surveillance colonoscopy or sigmoidoscopy in the future. Conclusion: More than half of the pediatric endoscopic specialists in Korea choose between a colonoscopy and sigmoidoscopy depending on the patient's age, contrary to the generally accepted recommendation of total colonoscopy if colorectal polyps are suspected in children and adolescents. In this survey, most pediatric endoscopists used the age range of 4-9 years as the reference age.

Objectives: Colonoscopy is a popular tool for screening for colon cancer throughout the world. The incidence of polypectomy and follow-up colonoscopy are persistently increasing but the studies about follow-up test after polypectomy are still lack of its domestic sources. This study is designed to look into the recurrence rate of colon polyps and risk factors after polypectomy. Methods: This is a retrospective study by reviewing medical charts of 147 patients who underwent polypectomy and follow-up colonoscopy from Jan. 2000 to Mar. 2008. The Kudo classification was used to describe the polyps found in the colonoscopy. The follow-up period was defined as the term between polypectomy and the first colonoscopy follow up. Results: Seventy six point two percent of the enrolled patient were male and the mean age was $56.5{\pm}8.1$. Mean follow-up period was $24.9{\pm}13.7$ (6 - 65) months. The cumulative recurrence rate of 1 year was 11.6%. The rate of 2 years was 36.7% and that of 3 years was 55.8%. The number of polyps was the factor which statistically showed significant relation of its recurrence rate. The histological morphology characteristic of polyps could be one independent factor which may be associated to the recurrence of polyps. Conclusions: The importance of colonoscopy follow up after polypectomy was clearly emphasized through the cumulative recurrence rate of 55.8%. Therefore, there is a need for more domestic studies with a large number of patients about the recurrence of polyps after polypectomy.

Carcinoid tumors are derived from the enterochromaffin cells of neural crest origin. Most are commonly found in the gastrointestinal (GI) tract. The rectum is the third most common site for GI carcinoids. Rectal carcinoid tumors make up 13.7% of all carcinoid tumors and the vast majority occurs in the sixth decade of life. Approximately 80% of rectal carcinoid tumors are less than 1 cm in size, limited to the submucosa without metastasis and can be safely treated by local excision. We report a case of rectal carcinoid tumor in a 13 year-old child that was successfully treated by endoscopic polypectomy.

Peutz-Jeghers syndrome is an autosomal dominant inherited syndrome characterized by mucocutaneous pigmentation and gastrointestinal hamartomatous polyps. The most important complications that increase morbidity are intussusception, bleeding and obstruction. Most patients with Peutz-Jeghers syndrome may undergo multiple laparotomies for complications such as intussusception or bleeding every 2 to 3 years during adolescence and early adulthood. To decrease the relaparotomy rate, intraoperative endoscopy may be useful in the treatment of complications that are related to Peutz-Jeghers syndrome. Use of intraoperative endoscopy can lead to a healthier life and to a longer life expectancy for the patient. We describe a case of Peutz-Jeghers syndrome, who underwent polypectomy by total gut endoscopy in an 11-year-old girl presented with intestinal obstruction and anemia. During the course of the operation, the endoscope was inserted per the enterostomy and colostomy sites, and 16 polyps in the small and large intestine were removed endoscopically using a snare.
