Purpose: This study was a randomized single-blind trial of whole versus split-dose PEG solutions for colonoscopy preparation to compare the patient compliance, quality of bowel cleansing, and endoscopist's satisfaction. Methods: The participants were recruited from outpatients who planned to receive colonoscopy of C hospital in Busan. Sixty participants were randomly assigned to receive either a spit-dose group(n=30) consuming $2{\ell}$ of PEG solution twice, or a whole-dose group(n=30), consuming $4{\ell}$ of PEG solution once. These participants completed the questionnaire to assess their compliance before colonoscopy. The quality of bowel cleansing was assessed using the Ottawa Scale with the endoscopist who was blinded to the type of preparation, and their satisfaction by using VAS. Results: The participants who did not completely consume $4{\ell}$ of PEG solution were less in split-dose than in whole-dose group (0% vs 13.3%). The split-dose group complained less about abdominal pain(t=2.644, p=0.009) and abdominal bloating(t=2.802, p=0.013) with a statistical significance. For the quality of bowel preparation, there were no significant differences in the bowel cleansing scores and the endoscopist's satisfaction between two groups. Conclusion: Colonic preparation with split-dose of PEG solution could be a more useful method for better patient compliance, with no significant impact on bowel cleansing quality.

서구화된 식생활 등의 영향으로 국내에서 대장암의 빈도가 증가하고 있다. 건강에 대한 관심의 증가와 대장내시경 기술의 발달 및 건강검진의 영향으로 조기대장암의 진단 또한 증가하고 있지만, 상당수의 대장암 환자들이 대장 폐쇄의 임상적 증상을 호소한다. 이러한 환자들은 진행된 병기, 고령, 동반 질환 등으로 수술을 시행하기가 어려운 경우가 많고 대장이 불결한 상태에서의 응급 수술은 수술과 관련한 심각한 사망률 및 합병 이환율을 초래한다. 악성 대장 폐쇄에서 스텐트가 도입된 이래 최근 10여 년간 많은 연구들이 있었고 고식적 목적, 수술 전 감압 목적으로 그 역할이 인정되고 있는 듯하다. 대장 스텐트의 역할이 좀 더 구체화되기 위해서는 향후 잘 디자인 된 무작위 전향 연구가 필요하며, 특히 장기간에 걸친 연구 결과들이 뒷받침되어야 할 것으로 생각된다.

Purpose: This research is to know whether aroma foot massage has influence on the relief of anxiety and pain during colonoscopy under conscious sedation. Method: This research was designed as a quasi-experiment of non-equivalent control group pretest-posttest. Data were collected from April 1 2005 to August 30 2005. The subjects were divided into three groups (control group, foot massage group and aroma foot massage group) with 30 persons each. Anxiety was evaluated with Visual Analogue Scale (VAS), blood pressure and pulse. Pain response was measured with VAS and non-verbal pain behavior score. Sleep satisfaction was measured with a graphic rating scale. Data were analyzed through Chi-square test, t-test and repeated measure ANOVA. Results: Systolic blood pressure, pulse, subjective anxiety and pain scores from the aroma foot massage group decreased significantly. Sleep satisfaction score of the aroma foot massage group increased significantly. Diastolic blood pressure from the aroma foot massage group did not decrease. Conclusion: The results show that aroma foot massage with refined oils can increase sleep satisfaction and decrease anxiety and pain during colonoscopy under conscious sedation.

Purpose: The purpose of this study was to evaluate the effects of an educational video program on bowel preparation for a colonoscopy. Methods: The study used a non-equivalent control group and non-synchronized design as a quasi-experimental research involving 101 participants undergoing bowel preparation for a colonoscopy (experimental group 51, control group 50 subjects) at W. university hospital, from Aug. 7 to Oct. 31, 2013. The control group received verbal education with an explanatory note while the experimental group received education using a video program. To measure knowledge of diet restrictions and compliance with ingesting bowel preparation solutions, a questionnaire, based on The Korean Society of Gastrointestinal Endoscopy's Guide (2003), developed by Sam-Sook You, was used after revisions and supplementation was done. To measure bowel cleanness, the 'Aronchick Bowel Preparation Scale' was adopted. Data were analyzed using the SPSS WIN 12.0 program. Results: A higher proportion of the experimental group showed a positive change in knowledge level on diet restrictions (U=1011.50, p =.035) and ingestion of bowel preparation solutions (U=980.50, p =.019), a higher level of compliance with diet restrictions (U=638.50, p <.001), ingesting bowel preparation solutions (U=668.00, p <.001) and the level of bowel cleanness (${\chi}^2$=17.00, p <.001) than the control group. Conclusion: The results of this study indicate that a video educational program for patients having a colonoscopy can improve knowledge, level of compliance with diet restrictions, ingestion of bowel preparation solutions, and bowel cleanness. Therefore video educational program should be used with this patient group.

Purpose: This study was conducted to examine the effects of an educational program based on mobile SMS and counseling for colonoscopy in elderly people. Methods: The study utilized a non-equivalent control group with a non-synchronized design as a quasi-experimental research. The study subjects consisted of 72 elderly people (36 elderly people in the experimental group and 36 in the control group). Among the subjects, 49 were male (68.1%) and 23 were female (31.9%), and the age was 69.04±6.14 years. Forty-five subjects (62.5%) answered that they had underlying diseases, eight subjects (11.1%) had a family history of colon disease, and 61 subjects (84.7%) had undergone a colonoscopy. The experimental group was provided with an educational program based on mobile SMS and counseling when three days and one day before the test. The control group received verbal explanations using information sheet. The data were analyzed using descriptive statistics, the Chi-squares test, and the independent t-test with SPSS/WIN 21.0. Results: Significant differences were found in bowel cleanliness scores (t= 3.60, p= .003) between the groups. No significant differences were seen between the groups in the sedation drug dosage (propofol (t= 1.02, p= .730), midazolam (t= 0.66, p= .380)) and time for colonoscopy (t= 1.08, p= .235). Conclusion: Based on the results of this study, an educational program based on mobile SMS and counseling for colonoscopy was proposed as an educational program before colonoscopy.

본 연구에 목적은 연령별 대장용종의 발생과 경동맥 내중막 두께와의 상관관계를 알아보고자 하였다. 대장내시경과 경동맥 초음파를 동시에 시행한 환자를 대상으로 연령별로 나누어 경동맥 내중막 두께에 따라 대장용종 발생의 상관관계를 교차분석을 토대로 확인하였다. 분석결과 대사증후군 환자 중 연령별로 대장용종과 경동맥 내중막 두께와의 연관성은 고령일수록 높은 일치결과를 나타냈고, 경동맥 내중막 두께가 1.1mm이상일 때 용종발생비율이 높게 나타났다. 결론적으로 대사증후군 환자의 용종발생비율은 경동맥 초음파 검사와 대장내시경과 높은 상관관계가 있었고, 고령일수록 경동맥 내중막 두께가 두꺼울수록 높았다.

For robotic endoscope, some researchers suggest pneumatic actuators based on inchworm motion. But, the existing endoscopes are not seemed to be replaced completely because human intestine is very sensitive and susceptible to damage. We design and test a new locomotion of robotic endoscope able to maneuver safely in the human intestine. The actuating mechanism is composed of two solenoids at each side and a single permanent magnet. When the current direction is reversed, repulsive force and attractive at the opposition side propels permanent magnet. Impact force against robotic endoscope transfer momentum from moving magnet to endoscope capsule. The direction and moving speed of the actuator can be controlled by adjusting impact force. Modeling and simulation experiments are carried out to predict the performance of the actuator. Simulation experiments show that force profile of permanent magnet is the dominant factor for the characteristic of the actuator. The results of simulations are verified by comparing with the experimental results.

Conventional clonoscope is semiflexible tube that should be manipulated by operator for inspection and treatment. Therefore, it sometimes causes pain for the patient and even perforation to the wall of colon if a surgeon is not well trained. For safe colonoscopy, self-propelling robots with inchworm locomotion are studied. But, inchworm locomotion has some problems in adaptiveness to the variation of colon diameter. In this paper, we propose novel locomotive mechanism which can move in the colon without any external assistance. It has several cams that have constant phase difference each other and located along the centerline of the mechanism. This mechanism could realize the robotic endoscope which has continuous and smooth thrust force.
