Large bowel cancer correlates tightly to dietary factors such as dietary fiber and fat. Dietary fiber prevents the large bowel cancer in different modes of action which depend upon physicochemical and fermentable properties. Water-soluble fiber is fermented easily by intestinal microbes producing short chain fatty acids ; in contrast, water-insoluble fiber occurs effectively more rapid transit time due to greater bulk of gut content, though it is unfermentable. Not only short chain fatty acid is utilized in the proximal and distal colon as primary energy source, but also it lowers pH in the colon to normalize cellular differentiation and helps to stimulate peri staltic movement by acting as an osmotic laxative. In particular, butyric acid may also regulate gene expression and cell growth, though it is an important respiratory fuel for the colonocyte. Since dietary fiber and non-digestible oligosaccharides are the major source of butyric acid, this provides a possible link between dietary fiber and oligosaccharide and prevention of large bowel cancer. But, as with many links between dietary fiber and large bowel cancer, a direct casual association has not been established. In addition, RDA of dietary fiber which is 20~25g/day for adult Japanese, appears to be reasonable for the defecation once daily and the prevention of large bowel cancer.

Large bowel cancer shows the 4-5th frequency in cancers that occurs in Korea. The western medicine cures the Large bowel cancer by radiation, surgery and chemotherapy. While, Oriental medicine cures the Large bowel cancer by Herb-drugs, acupuncture, moxa and et al. With just one way of treating Large bowel cancer can't be effective remedy. Because each medicine has a strength and weakness, it is effective treatment when two medicine combines and supplement each other. We got the following result about a trend of oriental and western combination treatment for Large bowel cancer through studding records. 1. In Large bowel cancer, colon cancer is referred hematochezia(腸風下血), rectal cancer is refereed enterotoxin(腸毒), and anal cancer is accumulation of pathogens in yin(結陰). 2. The western medicine treats Large bowel cancer patient with surgery first. They need on assembly treatment such as chemical, radiation and immune treatment. In oriental medicine, they treats Large bowel cancer patients with differentiation of symptom and signs and treatment(辨證施治) for example, insufficiency of spleen and stomach(脾胃虛弱), collapse of the spleen-ql(脾氣下陷), stagnation of blood stasis and toxic agent(瘀毒內結), reinforcing both qi and blood(脾血下陷), stagnation of damp-phlegm(痰濕凝結) and cure for them by acupuncture and moxa too. 3. In combination with oriental and western medical treatment princple of Large bowel cancer by each stage is as follows. First stage is cured with radical surgery and herb-drugs without chemotherapy. The intermediate and terminal stage patients is used radiation before surgery, or after palliative surgery cour with chemotherapy, radiation and Herb-drugs. In terminal stage patients, unable for surgery, is used combination between chemotherapy, palliative radiation and Herb-drugs. 4. After radiation surgery, the terminal stage patients who have extensively lymph node metastasis or local contraindication is able to undergo combination of Herb-durgs and chemotherapy. 5. The cure-effect with oriental and western medicine combination treatment was better than that just with oriental or western medical treatment. 6. The merits of oriental and western medicine combination treatment lengthen one's life and diminish the bad effect of chemotherapy and complete radiation treatment, prevent from relapsing, maintain the balance in their environment of body and improve immunity.

Large bowel cancer is one of the major causes of increasing world-wide cancer mortality. Our group has found a variety of naturally-occurring and synthetic compounds which have chemopreventive potentials against the occurrence of large bowel cancers using animal models. Aberrant crypt foci (ACF) which develop in rodents soon after the carcinogen exposure have been used as a biomarker for screening effective agents for cancer chemoprevention.(omitted)

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.

Cancer is the first leading cause of death in Korea and the second leading cause of death in the USA. There is extensive research into prevention of cancer and the support of oncology patients with diet or dietary supplements. In vitro and in vivo animal studies have indicated that antioxidants, including beta-carotene, alpha-tocopherol, and ascorbic acid, can yield anti-cancer effects in addition to providing protection against oxidative damage. Although many observational studies have shown that consuming fruits and vegetables can reduce the risk of some cancers, the results of several large-scale human intervention trials testing the benefits of a single or combined higher-dose of individual micronutrients have been inconsistent. Cancer can cause profound metabolic and physiological changes which may affect patients' nutrient requirements. Although the optimal route of nutrient delivery is through diet, cancer patients often suffer symptoms that disrupt their food intake, including anorexia, premature satiety, altered taste and smell, and changes in bowel mobility. In particular, micronutrient deficits can slow postoperative healing, contribute to depression symptoms, and decrease immune competence. Cancer patients are generally motivated to take dietary supplements to improve responses to treatment and quality of life. The Physician's Health Study II (PHS II) randomized controlled trial reported recently that daily multivitamin supplementation significantly, albeit modestly, reduced the risk of total cancer. Although evidence of multivitamin use benefits is limited in cancer patients, taking dietary supplements with constituents in the range of the recommended daily allowance according to the Dietary Reference Intake (DRI) recommendation is generally considered to be safe.

Herniation after harvesting of deep circumflex iliac artery (DCIA) flap is a known but not a common complication. It occurs about 2.8 to 9 % according to the literatures and can proceed to a more severe complication such as bowel obstruction. There are several factors that exacerbate the risk: surgical factors, operator factor, and patient factors. Surgical factors include large anatomical defect and denervation of related muscles. Operator factor stands for unpunctual suture technique. Patient factors represent obesity, diabetes, pulmonary disease, smoking habits, and so on. Thus, herniation might occur regardless of meticulous suture. Herein, we would like to report two cases of herniation after DCIA flap harvesting and repaired by Lichtenstein tension-free hernioplasty with literature review.

Computed Tomography Colonography (CTC) is a medical imaging technology used in identifying polyps and colon cancer masses in the large intestine. The technique has evolved a great deal since its invention and has become a routine diagnostic procedure in Western countries due to its non invasiveness and ease of use. The objective of our study was to explore the possibility of CTC application in Indian hospitals. This paper gives an overview of the procedure and its commercial viability. The explanation begins with the domain aspects from gastroenterologist perspective, the new way of thinking in polyp classification, the technical components of CTC procedure, and how engineering solutions have helped clinicians in solving the complexities involved in colon diagnosis. The colon cancer statistics in India and the results of single institution study we carried out with retrospective data is explained. By considering the increasing number of patients developing colon malignancies, the practicality of CTC in Indian hospitals is discussed. This paper does not reveal any technical aspects (algorithms) of engineering solutions implemented in CTC.

Background: Colorectal cancer (CRC) is the most common gastrointestinal malignancy and is a significant cause of mortality. Its incidence is generally increasing in Asia. Reports from the West have indicated that the incidence of rectal cancer is increasing in the younger population. This study assessed the time trend of CRC in Brunei Darussalam specifically assessing the different age groups at which the incidences start to increase. Materials and Methods: The National Cancer registry was reviewed (1991 to 2014). The age standardized rate (ASR) and the age specific incidence rates (ASIRs) for three time periods (1991-1998), (1999-2006) and (2007-2014) were calculated. Results: The mean age of diagnosis was $59.3{\pm}14.6$ years old, incidences being slightly higher amongst men (57.6%) and Malays (67.1%). The most common tumor type was adenocarcinoma (96.4%). Rectal cancers accounted for 35.2% (n=372/1,056) of all cancers of the large bowel; more men were affected than women. The proportion of rectal cancer was also high among the indigenous group. In the three time periods, the ASR for CRC increased from 16 per 100,000 (1991-1998) to 19.6 per 100,000 (1999-2006) and 24.3 per 100,000 (2007-2014). The ASIRs for CRC increased markedly between the time periods 1998-2006 and 2007-2014, beginning in the 40-44 years age group. For rectal cancers, the ASIRs started to increase in the 25-29 age group onward whereas for colon cancers, the increase was observed at a later age, starting from the 45-49 age group. Conclusions: Our study showed an increase in the incidence of CRC including in the younger age groups. The increase was seen earlier in rectal cancer compared to colon cancer. These data mirror the trends reported from the West.

Background: Colorectal cancer is currently the third most common cancer in Indonesia, yet colonoscopy - the most accepted mode of screening to date - is not done routinely and national data are still lacking. Objective: To determine the detection rate of colorectal cancers and adenomas in unselected patients undergoing colonoscopy for various large bowel symptoms at the Digestive Disease and GI Oncology Centre, Medistra Hospital in Jakarta, Indonesia. Materials and Methods: Colonoscopy data from January 2009 to December 2012 were reviewed. New patients referred for colonoscopy were included. Data collected were patient demographic and significant colonoscopy findings such as the presence of hemorrhoids, colonic polyps, colonic diverticula, inflammation, and tumor mass. Histopathological data were obtained for specimens taken by biopsy. Associations between categorical variables were analyzed using chi-square test, while mean differences were tested using the t-test. Results: A total of, 1659 cases were included in this study, 889 (53.6%) of them being men. Polyps or masses were found in 495 (29.8%) patients while malignancy was confirmed in 74 (4.5%). Patients with a polyp or mass were significantly older (60.2 vs 50.8 years; p<0.001; t-test) and their presence was significantly associated with male gender (35.0% vs 23.9%; prevalent ratio [PR] 1.71; 95% confidence interval [CI] 1.38-2.12; p<0.001) and age >50 years (39.6% vs 16.6%; PR 3.29; 95% CI 2.59-4.12; p<0.001). Neoplastic lesions was found in 257 (16.1%), comprising 180 (11.3%) adenomas, 10 (0.6%) in situ carcinomas, and 67 (4.2%) carcinomas. Conclusions: Polyps or masses were found in 30% of colonoscopy patients and malignancies in 16.1%. These figures do not represent the nation-wide demographic status of colorectal cancer, but may reflect a potentially increasing major health problem with colorectal cancer in Indonesia.
