  • 목 적: 본 연구에서는 췌장암 환자 MRgART(Magnetic Resonance-guided Adaptive Radiation Therapy)시 복부가스용적변화로 인하여 Image fusion 과정에서 생길 수 있는 조직과 가스의 전자밀도 매칭오류를 확인하고 그에 따른 선량 변화와 치료시간에 미치는 영향을 확인해 보고자 한다. 대상 및 방법: 본원에서 ViewRay MRIdian System (Viewray, USA)를 이용하여 MRgART를 시행한 췌장암 환자 중 최초 simulation시와 비교하여 복부가스용적감소가 발생한 환자를 대상으로 Initial plan과 복부가스 전자밀도를 수정한 AGC(Abdominal gas correction) plan의 PTV와 OAR선량을 비교하였고, 총4회 Adaptive 치료에서 환자의 Beam ON(%)을 확인하여 복부가스용적이 치료시간에 미치는 영향을 확인해 보았다. 결 과: Initial plan에서의 Mean, Minimum, Maximum 선량과 AGC plan의 Mean, Minimum, Maximum 선량평균값을 비교하였을 시 OAR에서는 -7~0.1%의 선량차이를 보였으며 평균 0.16% 감소하였고, PTV에서는 4.5~5.5%의 선량이 감소하였으며 평균 5.1%의 선량이 감소하였다. Adaptive치료 시 복부가스용적이 증가할수록 Beam ON(%)이 감소하였다. 결 론: Initial plan과 Adaptive plan간 복부가스용적 변화는 Adaptive plan시 전자밀도매칭 오류로 이어질 수 있으며 이는 PTV와 주변OAR의 선량분포를 변화시키므로 Adaptive plan시 영상 fusion 과정에서 가스용적을 보정한 정확한 전자밀도매칭은 필수적인 요소이다. 또한 복부가스용적이 커질수록 Beam ON(%)이 감소하여 환자의 Motion error로 인한 치료시간이 증가될 수 있다. 따라서 MRgART시에는 전자밀도매칭을 확인하고 복부가스의 가변성을 최소화 하여야 한다.

  • Purpose: This study was aimed to investigate the effects of gum-chewing on the recovery of bowel movement and oral cavity discomfort after abdominal surgery. Method: The nonequivalent control group, non-syncronized repeated treatment design was used. A total of 99 patients were participated in the study. The 44 patients were in the experimental group and the rest in the control group. The experimental group chewed gum three times a day until they passed gas. As the patient reported gas-passing, bowel movement time, subjective symptoms of oral cavity, and oral status were recorded precisely. The frequency, percentage, $x^2$-test and t-test were analyzed by SPSS PC 12.0. Results: There were significant differences in bowel movement, gas passing, oral cavity symptoms, and oral status scores between the experimental and the control group. Conclusion: The findings of the study demonstrated the fact that gum-chewing helps early recovery from post-operative ileus and thirst. It is because gum chewing stimulates bowel mobility and secretion of saliva. Thus gum-chewing seems to be an effective nursing intervention in reducing post-operative side effects for patients with abdominal surgery.

  • In this retrospective study the effect of positioning on the radiographic appearance of duodenum and the radiographic differences of duodenal gas pattern between dogs without pancreatitis and dogs with pancreatitis were investigated. Ventrodorsal, dorsoventral as well as both lateral abdominal radiographs of 255 dogs were evaluated. Gas distribution in the duodenum, gastroduodenal angle, accuracy of the positioning was examined. The duodenum was more visible in a left lateral view and a dorsoventral view. The positioning of dorsoventral view was the most inaccurate. Based on this study, there were not significant differences in duodenal gas pattern between dogs without pancreatitis and dogs with pancreatitis.

  • Objectives: The purpose of this study was to propose a diagnostic method for classifying patients with dyspepsia by symptom type. The correlation between symptom types and X-ray findings was studied in 62 patients with indigestion. Methods: In this study, the complaints and abdominal X-ray findings were collected for 62 patients who visited the outpatient Korean medicine clinic. The medical information related to dyspepsia was grouped for similar patients and classified by symptom type. Results: The patients with dyspepsia were classified into three types according to their medical symptoms: Distention type (N=43, 68.3%), Abdominal Pain type (N=16, 25.5%), and Constipation type (N=12, 19.0%). Intestinal fecal findings (80.6%) on x-rays were noted in most of the cases, followed by intestinal gas pattern findings (14.5%). Conclusion: Classifying patients with dyspepsia by symptom types is an appropriate diagnostic method due to the unclear pathophysiology of indigestion and the difficulty in applying a Korean medical dialectic. Irrespective of the symptom types, the large number of fecal material findings (80.6%) on x-rays means an effect on the interior environment of the body where intestinal feces accumulate easily and decreased gastrointestinal motility in patients with indigestion. This can be correlated with "food accumulation (食積)" as intestinal feces are tangible substances. In addition, gas in the intestine increases visceral sensitivity, causing abdominal distention or pain. The gas pattern findings (14.5%) on x-ray were observed in the "Distention type" and "Abdominal pain type," but not in the "Constipation type."

  • Purpose: The purpose of this study was to compare differences in the time when bowel sounds were heard and gas was passed in women who had an abdominal hysterectomy and were treated for 5 minutes (experimental group A) or 10 minutes (experimental group B) with San-Yin-Jiao (SP-6) acupressure. Method: The design of this study was a nonequivalent control group non-synchronized post test only design. The participants included 142 women, 39 in experimental group A, 30 in experimental group B, and 73 in the control group. Data was collected using a structured questionnaire which included items on general characteristics and a self report of time when gas was passed. Differences for the three groups as to time when bowel sounds were heard and gas was passed were analyzed using ANOVA. Result: The time when bowel sounds were heard was statistically significantly shorter in both experimental groups compared to the control group(F=10.29, p=.000). The time when gas was passed was statistically significantly shorter in experimental group B(10 min) compared to the control group(F=4.68, p=.011). Conclusion: It could be concluded that SP-6 acupressure of 10 minutes was effective in shortening the time until bowel sounds were heard and gas was passed for women who had had an abdominal hysterectomy. Replication of the study with a larger number of participants is necessary in order to be able to generalize the results.

  • Objectives The purpose of this study is to report the case of fecal impaction in a child without any abdominal symptoms treated by taking herbal medicine. Methods We examined a 7-year-old girl who had normal bowel movement and defecation per day, and had no particular abdominal symptoms. Abdominal radiography was taken, and unexpected severe fecal impaction was observed throughout the abdominal cavity, filled with intestinal gas and feces. According to the subject's parents, she had no generalized symptoms, such as abdominal pain or distension, and had on a regular diet and normal bowel movement daily. She was treated with herbal medicine (Daeseunggi-tang) for 23 days. While she was on the therapy, numbers, doses, bowel movements, and radiography were checked and recorded. Results During the treatment, her stool was softened, and fecal impaction was relieved as showed by abdominal radiography. Conclusions We have identified that there are cases where subjects have no symptoms of abdominal pain, despite presence of severe fecal impaction. In addition, it was found that Daeseunggi-tang is effective in fecal impaction in childhood.

  • Purpose: Although ultrasonography is the gold standard of diagnosing intussusception, plain abdomen radiograph (AXR) is often used to make differential diagnosis for pediatric patients with abdominal pain. In intussusception patients, we aimed to analyze the AXR and clinical data to determine the characteristics of early AXR findings associated with diagnosis of intussusception and recurrence after reduction. Methods: Between January 2011 and June 2018, 446 patients diagnosed with intussusception based on International Classification of Diseases-10 code of K56.1 were admitted. We retrospectively reviewed medical records of 398 patients who received air reduction; 51 of them have recurred after initial reduction. We evaluated six AXR features including absent ascending colon gas, absent transverse colon gas, target sign, meniscus sign, mass, and ileus. Clinical data and AXR features were compared between single episode and recurrence groups. Results: Two groups did not show significant differences regarding clinical data. Mean time to recurrence from air reduction was 3.4±3.2 days. Absent ascending colon gas (63.9%) was the most common feature in intussusception, followed by mass (29.1%). All of six AXR features were observed more frequently in the recurrence group. Absent transverse colon gas was the most closely associated AXR finding for recurrence (odds ratio, 2.964; 95% confidence interval, 1.327-6.618; p=0.008). Conclusion: In our study, absence of ascending colon gas was the most frequently seen AXR factor in intussusception patients. Extended and careful observation after reduction may be beneficial if such finding on AXR is found in intussusception patients.

  • Hepatic portal venous gas (HPVG) is a rare radiographic finding associated with severe intra-abdominal disease and fatal outcome. Most cases of HPVG are historically related to mesenteric ischemia accompanied by bowel necrosis. The current spread of computed tomography scan promotes not only the early detection of related severe diseases but also the identification of other causes of HPVG. It has been reported in many non-fatal conditions, such as inflammatory bowel disease, intra-abdominal abscess, bowel obstruction, paralytic ileus, endoscopic retrograde cholangiopancreatography and endoscopic sphincterotomy, and gastric dilatation. Among these, paralytic ileus is a very rare condition, with no case yet reported in South Korea. Reported herein is a case of HPVG in paralytic ileus, which was treated well internally and was promptly resolved.
