Résumé
Complications after colorectal surgery remain inevitable, and anastomotic leakage is one of the most severe and potentially fatal complications. Generally, anastomotic leakage is associated with severe peritonitis, the need for emergency reoperation, and an increased mortality rate. Additionally, particularly after rectal cancer surgery, it has a negative impact on long-term outcomes, including postoperative anorectal function, local recurrence, and survival. To prevent anastomotic leakage, understanding the characteristics of each anastomotic technique and establishing a stable anastomotic procedure are important. Transanal total mesorectal excision (TaTME) is a relatively new advanced surgical access technique for pelvic dissection and facilitates different anastomotic techniques without the need for transabdominal rectal transection. Especially, stapled anastomosis in TaTME, also known as double purse-string circular stapled anastomosis or the single stapling technique (SST), has gained much attention as an alternative to the conventional double stapling technique (DST). In this article, we describe the DST, SST, and hand-sewn anastomosis as anastomotic techniques after rectal surgery, focusing mainly on the differences between conventional anastomotic techniques and SST in TaTME. Furthermore, the blood flow evaluation method for the reconstructive colon before anastomosis, which is extremely important in anastomotic leakage prevention regardless of the anastomotic type, is also described.
Résumé
Colorectal cancer patients account for the largest proportion of total cancer patients in Japan. With an increase in its surgical cases and relatively higher five-year survival rate, the number of cancer survivors is expected to be increasing. Therefore, primary prevention, surgical therapy and recurrence prevention for colorectal cancer are public health priorities in Japan. General and abdominal obesity (Not only abdominal but also general obesity) are risk factors for colorectal cancer. In addition, accumulated abdominal fat can extend time spent in surgery by hindering operative procedures and surgical field expansion. These factors raise the risk of postoperative complications such as bleeding and surgical site infection, which eventually leads to increased medical expenses. Physical activity is one of protective factors for colorectal cancer. Recent studies showed that exercise intervention in cancer survivors reduces the cancer recurrence risk. Furthermore, it has been suggested that exercise interventions are effective in reducing fatigue, improving immune function, and maintaining physical function. However, the effectiveness of preoperative exercise intervention aimed at reducing weight in colorectal cancer patients remains unknown. In this review article, we discuss necessity for peri-operative weight loss among obese colorectal cancer patients.
Résumé
<p> The education program in all medical schools in Japan has been studied and analyzed every 2 years since 1974 by the curriculum committee of the Association of Japan Medical Colleges. Based on the most recent analysis in 2015, the marked innovation of medical education, such as an integrated curriculum, active learning, and clinical clerkship, was recognized.</p>
Résumé
1) A program entitled Doc MMC was broadcast on FM Mie, a local FM radio station.“The Doc MMC Declaration”was performed on this program by residents.<BR>2) The declarations were classified into six groups: “Affection, ”“Contribution to Community Medicine, ”“Knowledge and Skill, ”“Special Training Course Selection or Self-Activation, ”and “Others.”<BR>3) This kind of broadcasting may enhance the motivation of residents and facilitate the understanding of medical issues by the community.
Résumé
1) The faculty development at each medical school from 2003 through 2005 was analysed.<BR>2) The major themes in faculty development were problem based learning, tutorial, computer based testing, and clinical training.<BR>3) Faculty development is considered an effective way to enhance the contributions of faculty members to medical education.
Résumé
At the Niigata University School of Medicine, objective structured clinical examinations (OSCEs) were performed for the first time in 2001 for 92 fourth-year medical students. The average evaluation scores students received from instructors were summarized, and the differences between scores given by different instructors were examined. We found that practice methods for the medical interview and physical examination before OSCE and the question topics and evaluation methods of OSCE were appropriate, but scores on some items were extremely low. The standardization and objectivity of the evaluation were satisfactory, perhaps because one explanatory conference and two training conferences were held for instructors before OSCE. However, some questions tended to produce differences between instructors, as did some topics, especially in the medical interview. The scores with standardized patients and those by teachers were strongly correlated, but those with the former were lower than those by the latter.
