Purpose: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. Methods: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher`s-exact test and multiple logistic regression. Results: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). Conclusion: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.

Wang, Jin,Fan, Huan,Han, Ye,Zhao, Jinzhao,Zhou, Zhijiang Asian Australasian Association of Animal Productio 2017 Animal Bioscience Vol.30 No.1

Objective: The gastrointestinal tract of sheep contain complex microbial communities that influence numerous aspects of the sheep's health and development. The objective of this study was to analyze the composition and diversity of the microbiota in the gastrointestinal tract sections (rumen, reticulum, omasum, abomasum, duodenum, jejunum, ileum, cecum, colon, and rectum) of sheep. Methods: This analysis was performed by 454 pyrosequencing using the V3-V6 region of the 16S rRNA genes. Samples were collected from five healthy, small tailed Han sheep aged 10 months, obtained at market. The bacterial composition of sheep gastrointestinal microbiota was investigated at the phylum, class, order, family, genus, and species levels. Results: The dominant bacterial phyla in the entire gastrointestinal sections were Firmicutes, Bacteroidetes, and Proteobacteria. In the stomach, the three most dominant genera in the sheep were Prevotella, unclassified Lachnospiraceae, and Butyrivibrio. In the small intestine, the three most dominant genera in the sheep were Escherichia, unclassified Lachnospiraceae, and Ruminococcus. In the large intestine, the three most dominant genera in the sheep were Ruminococcus, unclassified Ruminococcaceae, and Prevotella. R. flavefaciens, B. fibrisolvens, and S. ruminantium were three most dominant species in the sheep gastrointestinal tract. Principal Coordinates Analysis showed that the microbial communities from each gastrointestinal section could be separated into three groups according to similarity of community composition: stomach (rumen, reticulum, omasum, and abomasum), small intestine (duodenum, jejunum, and ileum), and large intestine (cecum, colon, and rectum). Conclusion: This is the first study to characterize the entire gastrointestinal microbiota in sheep by use of 16S rRNA gene amplicon pyrosequencing, expanding our knowledge of the gastrointestinal bacterial community of sheep.

목적: 내시경 검사의 빈도가 늘면서 이전에는 매우 드물던 유암종의 빈도도 늘고 있다. 특히 대장 내시경을 시행하면서 우연히 발견되는 작은 유암종들은 내시경적 절제술 및 외과적 국소절제술을 통하여 비교적 간단히 치료되고 있다. 저자들은 이러한 하부위관 유암종의 임상적 특징과 치료 결과 및 재발 등에 대해 분석하고자 하였다. 대상 및 방법: 1999년 9월부터 2009년 9월까지 10년간 충북대학교병원에서 하부위장관의 유암종을 진단받은 41명의 환자를 후향적으로 조사하였다. 결과: 41명의 환자 중 남녀비는 1:0.64 이었고, 평균 연령은 47.4±12.4세였다. 41명의 환자 중직장 유암종이 38예(92.7%), 충수돌기 유암종이 2예(4.9%), S자결장 유암종이 1예(2.4%)였다. 내시경을 통한 유암종의 육안적 평균 크기는 9.4±4.8 mm였다. 초기치료를 시행받은 41명 중 수술적 절제를 시행받은 사람이 12명(29.3%), 내시경적 절제를 시행받은 사람이 29명(70.7%)이었다. 수술적 절제를 시행한 군의 평균 크기는 13.8±5.8 mm였고 내시경적 절제를 시행한 군의 평균 크기는 8.0±3.4 mm로 차이가 있었다 (P=0.011). 초기 치료 후 절제연 종양 양성을 보인 예는 총 41예 중 10예(24.4%)로 용종절제술을 시행하였던 28예 중에서 10예 모두가 발생(35.7%)하여 용종절 제술이 다른 치료방법에 비하여 유의하게 높은 치료후 절제연 종양 양성을 나타내었다(P=0.013). 41명의 환자 중 29명(70.7%)에서 추적 관찰이 이루어졌다. 이들의 평균 추적 관찰 기간은 19.2±14.5개월이었다. 재발은 추적 관찰하던 29명 중 직장 유암종으로 치료받았던 2명(6.1%)에서 발생하였다. 결론: 하부위장관의 유암종은 내시경적 절제술을 통해 쉽게 절제될 수 있으나 용종절제술의 경우 비교적 높은 절제연 종양 양성률(35.7%)을 보여 보다 신중한 치료적 접근이 필요하다. 또한 작은 크기의 직장 유암종도 재발의 가능성은 있으므로 추적 관찰은 반드시 시행되어야 하겠다. Background/Aims: The increase of colonoscopy procedures has led to an increase in the diagnosis of carcinoid tumors in the lower gastrointestinal tract. The purpose of this study was to identify the clinical and pathological characteristics that affect the treatment and recurrence of carcinoid tumors of the lower gastrointestinal tract. Methods: A 10-year (1999-2009) retrospective analysis of 41 patients with carcinoid tumors of the lower gastrointestinal tract at the Chungbuk National University Hospital was conducted. Patient and tumor characteristics, treatment and recurrence were analyzed. Results: The mean age was 47.4±12.4 (range, 22-79 years) and the male to female ratio was 1:0.64. The mean tumor size was 9.4±4.8 (3-20) mm. In the lower gastrointestinal tract, the rectum was the most frequent location of the lower gastrointestinal carcinoid tumors (92.7%). Twenty-nine out of 41 patients were treated by endoscopy (mean size of tumor: 8.0±3.4 mm) and 12 were treated by surgery (mean size of tumor: 13.8±5.8 mm)(P=0.011). Among the patients treated by endoscopy, only one patient had a complete resection. However, the histology showed that 10 patients treated by endoscopy had positive resection margins; all 10 cases (35.7%) had a polypectomy (P=0.013). The mean follow-up duration was 19.2±14.5 months, and there were two recurrences of rectal carcinoid tumors. Conclusions: Both endoscopic and surgical resections were effective methods for the treatment of lower gastrointestinal carcinoid tumors. However, endoscopic polypectomy should be carefully considered because of the possibility of more frequent incomplete histological resections. Moreover, even for small rectal carcinoid tumors, follow-up examination should be performed to evaluate for tumor recurrence. (Intest Res 2010;8:142-150)

The Effects of Fiber Source on Organ Weight, Digesta pH, Specific Activities of Digestive Enzymes and Bacterial Activity in the Gastrointestinal Tract of Piglets

Ma, Yongxi,Li, Defa,Qiao, S.Y.,Huang, C.H.,Han, In K. Asian Australasian Association of Animal Productio 2002 Animal Bioscience Vol.15 No.10

The aim of this study was to explore the effects of fiber sources on gut development and bacterial activity in the gastrointestinal tract of piglets. Eighteen crossbred (Duroc${\times}$Landrace${\times}$Yorkshire) barrows were fed a basal diet based on corn plus soybean meal or similar diets in which a portion of the corn and soybean was replaced by 5% wheat bran or 5% sugar beet pulp. The results indicate that pigs fed diets containing 5% wheat bran or 5% sugar beet pulp had lower liver weights than control pigs (p<0.01). The relative weight of the pancreas in pigs fed diets containing 5% sugar beet pulp was greater than that of control pigs or pigs fed diets containing 5% wheat bran (p<0.05). The pH of the ileal digesta of pigs fed the diet containing 5% wheat bran was higher than that of control pigs or pigs fed the diet containing 5% sugar beet pulp (p<0.05). The lipase activity in the distal jejunum, proximal, and distal ileum of pigs fed the control diet was higher than that of pigs fed the diets containing 5% wheat bran or 5% sugar beet pulp (p<0.05). The concentration of volatile fatty acids anterior to the caecum was greater for the pigs fed the diet containing 5% sugar beet pulp, while the concentration of volatile fatty acids posterior to the ileum was greater for the pigs fed the diet containing 5% wheat bran. This means that sugar beet pulp increased the bacterial fermentation precaecum, while wheat bran increased the bacterial fermentation post-ileum. The concentration of bacterial nitrogen and bacterial protein/total protein in ileal digesta of pigs fed the control diet was higher (p<0.05) than that of pigs fed the diets contained either fiber source. Bacterial protein/total protein in the feces of pigs fed the diet containing 5% sugar beet pulp was higher than that of pigs fed the control diet. This means that inclusion of 5% wheat bran or sugar beet pulp in diets influenced the development of the digestive tract of piglet. The mechanism by which dietary fiber reduced specific activity of lipase needs further consideration. Dietary fiber influenced the bacterial activity in the digestive tract of piglets, sugar beet pulp increased the fermentation in the upper gastrointestinal tract, and while wheat bran increased the fermentation in the lower gastrointestinal tract.

To determine the colonization ability of <I>E. coli</I> 3D8scFv, <I>E. coli</I> cells with or without the <I>3D8scFv</I> gene were fed to mice. Total DNA was extracted from the animals’ stools, stomach, small intestine and colon.

이영섭,강계월,최원규,Lee, Young-Sub,Kang, Kae-Wool,Choi, Won-Kyu 대한소아소화기영양학회 2001 Pediatric gastroenterology, hepatology & nutrition Vol.4 No.2

목적: 소아의 위장관 이물은 일상 생활에서 흔히 경험하는 질환으로 대개의 경우는 합병증 없이 자연 배출된다. 저자들은 내시경과 Foley 도관을 이용한 위장관 이물 적출술에 관한 최근 경향을 알아보고자 한다. 방법: 1996년 1월부터 1999년 12월까지 4년간 원주기독병원 소아과에 위장관 이물로 내원한 60례를 대상으로 하였으며 성별, 연령, 임상 증상, 이물의 종류와 위치, 이물의 치료 및 제거 방법, 합병증 등에 대하여 후향적으로 조사하였다. 결과: 위장관 이물 환자의 연령은 7개월에서 13세까지였으며, 5세 이하가 57례(95.0%)를 차지하였으며, 남녀비는 1.07:1이었다. 임상 증상은 무증상이 45례(75.0%)로 가장 많았고 연하곤란 8례(13.3%), 인후통 5례(8.3%), 구토, 복부 불쾌감이 각각 1례(1.7%)였다. 이물의 종류는 동전이 43례(71.7%)로 가장 많았고 구슬, 바둑알, 반지 등이 각각 3례(5.0%), 수은 건전지가 2례(3.3%)였으며 그 외 금속 clip, 나사못, 커튼핀, 머리핀, 오디오 열쇠, 스티커 등이 각각 1례(1.7%)씩 있었다. 이물의 위치는 식도 31례(51.6%), 위 25례(41.7%), 소장 3례(5.0%), 인후 1례(1.7%)였고, 이 중 식도 이물은 경부식도 24례(40.0%), 원위식도 5례(8.3%), 흉부식도 2례(3.3%)에서 관찰되었다. 유연성 내시경적 이물 제거를 시행한 경우가 22례(36.7%)로 가장 많았고, Foley 도관을 이용한 경우가 18례(30.0%), Forcep를 이용한 경우가 1례(1.7%)였다. 18례(30.0%)에서는 자연 배출되었고, 1례(1.7%)에서는 수술을 시행하였다. 결론: 소아에서 상부 위장관 이물은 조기에 제거하여 이환율과 합병증을 감소시켜야 하며, 식도이물의 제거시 X-선 투시하의 Foley 도관과 내시경은 소아에서 안전하고, 효과적인 이물적출방법이다. 얇고, 날카로운 이물은 주위 깊은 관찰을 요하며, 하부 위장관에 위치시 장천공에 대한 주위 깊은 관찰을 요한다. Purpose: Ingested foreign bodies present a common clinical problem. It is well known that most of them pass uninterrupted through the gastrointestinal tract. We evaluated the role of endoscopy and Foley catheter for removal of foreign bodies in the gastrointestinal tract. Methods: We investigated retrospectively 60 cases with foreign bodies in the gastrointestinal tract. They had been treated at Wonju Christian Hospital, Yonsei University of Korea, from January, 1996 through December, 1999. Results: The age of the patients ranged from 7 months to 13 years. Patients under 5 years were 57 cases (97%) and there was no significant difference in sex (M : F=1.07 : 1). 45 cases of the patients had no symptom. The most common foreign bodies were coins (43 cases). The most common location was esophagus (31 cases). The number of foreign body removal using flexible endoscopy and Foley catheter was 22 (36.7%) and 18 (30.0%) cases, respectively. In 18 cases (30.0%), foreign bodies passed spontaneously. Only 1 case (1.7%), curtain pin impaction at ileocecal region, required surgery. Conclusion: Early foreign body removal from esophagus and stomach is recommended to lessen the morbidity and complication. Fluoroscopic foley catheter technique and flexible endoscopy for removal of esophageal foreign bodies in children is safe and effective.

Omair Rashed Abdulwareth Alman,Mohd Azraai Mohd Razman,Ismail Mohd Khairuddin,Muhammad Amirul Abdullah,Anwar P.P. Abdul Majeed 제어로봇시스템학회 2021 제어로봇시스템학회 국제학술대회 논문집 Vol.2021 No.10

Colorectal cancer is a leading cause of death among the cancer family with a record of almost a million moralities in 2020 alone. While the treatment of colorectal cancer is very difficult, early diagnosis can help immensely with treatment, eliminating the risks, and recovery. In most cases early diagnosis is possible by catching any of the precursors of the disease, many of which appear on the Gastrointestinal tract. The use of machine learning to automate the process of gastrointestinal tract examination could accelerate the process of diagnosis, and increase its efficiency. This study suggests the use of the stacking ensemble method with multiple pre-trained CNN models for an accurate classification of GI tract using the publicly available dataset Kvasir. The pre-trained models used in this study were ResNet50, MobileNetV2, and Xception, all of which were ensembled and trained on a subset of the data and tested on another to eliminate bias, and evaluates the model’s capacity for generalization. Overall, the model demonstrated impressive performance at 99.2% accuracy, 0.9977 AUC, and 99.29% F1-score, especially compared to the individual constituent models and other models discussed in the review section of the study.

위장관 점액성 선암의 CT소견

김정희 대한영상의학회 1996 대한영상의학회지 Vol.34 No.4

Purpose : To evaluate CT findings of mucinous adenocarcinoma in the gastrointestinal tract. Materials and Methods : CT scans of 24 gastric and five colorectal mucinous adenocarcinomas, proven by histology, were retrospectively analysed; the patients consisted of 18 men and 11 women (age range, 27-76; mean, 59). CT findings were analysed, with emphasis on : (a) tumor size and maximal wall thickness ; (b) the presence of a low attenuation area, suggestive of a mucin pool within the tumor ; (c) the presence, shape and location of calcification, and (d) correlation between primary tumor (T) staging and CT findings. Results : The mean tumor size of gastric mucinous adenocarcinoma was 8.2cm (range, 1.4-17cm) and the mean maximal wall thickness was 2.3cm (range, 1-4.5cm). Low attenuation areas on enhanced CT were seen in 12 cases (50%). Mottled, punctate, diffuse calcifications were demonstrated in nine cases (38%), and were located in low attenuation areas in eight cases. The T staging could be determined in 22 cases. Of there, low attenuation areas were demonstrated in ten cases and calcification in seven. Of those ten cases with low atteuation area T staging was T2 in two cases, T3 in two, and T4 in six. Of the cases showing calcification, T staging was T3 in one case and T4 in six. The mean size of colorectal mucinous adenocarcinoma was 6cm (range, 3-13cm) and the mean maximal wall thickness was 3.6cm (range, 1.5-7cm). Low attenuation area were seen in three cases. Mottled calcification within the low attenuation was detected in one case. The T staging of three cases which showed a low attenuation area was T3 in two cases and T4 in one case. One case with calcification was T3 stage. Conclusion : The CT finding of mucinous adenocarcinoma in the gastrointestinal tract was a relatively thick-walled mass containing an area of low attenuation or calcification. Although calcification is believed to be a pathognomonic finding for the specific diagnosis of mucinous adenocarcinoma, a low attenuation area may be an important CT finding because it can be detected at lower T staging and more frequently.

Cystic Lesions of the Gastrointestinal Tract: Multimodality Imaging with Pathologic Correlations

이종미,박철민,김경아,이창희,최재웅,신봉경,이순진,최동일,장기택 대한영상의학회 2010 Korean Journal of Radiology Vol.11 No.4

The cystic lesions of the gastrointestinal (GI) tract demonstrate the various pathologic findings. Some lesions may present a diagnostic challenge because of non-specific imaging features; however, other lesions are easily diagnosed using characteristic radiologic features and anatomic locations. Cystic masses from the GI tract can be divided into several categories: congenital lesions, neoplastic lesions (cystic neoplasms, cystic degeneration of solid neoplasms), and other miscellaneous lesions. In this pictorial review, we describe the pathologic findings of various cystic lesions of the GI tract as well as the radiologic features of GI cystic lesions from several imaging modalities including a barium study, transabdominal ultrasound (US), computed tomography (CT), and magnetic resonance (MR) imaging.
