    A long-course antibiotic therapy increases the risk of antibiotic resistance. A 7- to 14-day duration of therapy has been traditionally adopted in patients with intra-abdominal infections (IAIs). Prophylactic antibiotic use is warranted in uncomplicated IAIs, in which the infection involves a single organ, and the source of the infection is completely eradicated by a surgical procedure. A large, randomized clinical trial of the treatment of complicated IAIs recently demonstrated that a fixed 4-day course of antibiotic therapy was as effective as a long-course therapy in patients who underwent adequate source control. Considering the poor prognosis and lack of clear evidence available for shortening the duration of antibiotic therapy in patients who are critically ill or those with ongoing signs of sepsis, the duration of therapy for complicated IAIs should be individually determined according to the clinical course. Limiting therapy to no more than 7 days seems to be warranted in patients who are critically ill with a good clinical response.

    Lynch syndrome is a hereditary cancer syndrome caused by germline mutations in one of several DNA mismatch repair genes. Lynch syndrome leads to an increased lifetime risk of various cancers, particularly colorectal, and endometrial cancers. After identifying patients suspected of having Lynch syndrome by clinical criteria, computational prediction models, and/or universal tumor testing, genetic testing is performed to confirm the diagnosis. Before and after genetic testing, genetic counseling should be provided. Genetic counseling should involve a detailed personal and family history, information on the disorder and genetic tests, discussion of the management and surveillance of the disease, career plan, family plan, and psychosocial support. Surveillance of colorectal cancer and other malignancies is of paramount importance for properly managing Lynch syndrome. This review focuses on important considerations in genetic counseling and the latest insights into the surveillance of individuals and families with Lynch syndrome.

    Objectives: Dietary guidance for patients with fecal incontinence (FI) in Japan is lacking. Here, we sought to investigate dietary trends of patients with FI. Methods: We performed a comparative study of dietary intake par day between patients with FI and the national mean. Our study group consisted of 100 female patients who consulted a dietitian about meals between June 2015 and March 2017. For national mean values, we used results from 3,332 women included in the 2015 National Health and Nutrition Survey (NHNS). Survey items included dietary fiber (DF), rice, wheat products, vegetables, fruits, and snacks. Results: No significant difference with respect to the overall DF (14.2 and 14.5 g, respectively; P=0.517) and vegetables (277.0 and 282.7 g, respectively; P=0.692) consumption was observed between the intake values reported in patients with FI and in NHNS. The intake of patients with FI was significantly lesser than that reported in NHNS for rice consumption (184.3 and 262.1 g, respectively; P<0.001). The intake of patients with FI was significantly higher than that reported in NHNS for wheat products (116.0 and 97.1 g, respectively; P<0.001), fruits (151.3 and 116.7 g, respectively; P=0.002), and snacks (45.5 and 28.8 g, respectively; P<0.001) consumption. Conclusions: Dietary trends for patients with FI revealed that the intake of rice was less, whereas that of wheat products, fruits, and snacks was much higher. Although the overall DF intake was about the same as the national mean, our results suggest that contents of DF differ between patients with FI and the NHNS.

    Objectives: Palliative stoma creation should be considered in patients at high risk of colonic metallic stent failure. However, it is unclear whether ileostomy or colostomy is superior. This study compared short-term outcomes between palliative ileostomy and colostomy. Methods: We identified 82 patients with malignant large bowel obstruction, caused by various advanced cancers, between January 2005 and December 2016. We compared short-term outcomes between the ileostomy group (n = 33) and the colostomy group (n = 49). Results: For all 82 patients, clinical success was achieved. Three patients with ileostomy died within 30 days of ostomy formation. The ileostomy group had statistically significant differences in median operative time (113 vs. 129 minutes, p = 0.045) and blood loss (8 vs. 40 g, p = 0.037) in comparison with the colostomy group. No statistically significant differences were observed in the surgical complications (30.3 vs. 38.8%, p = 0.431), in the median period to oral intake (3 vs. 4 days, p = 0.335) and in the hospital stay after surgery (32 vs. 27 days, p = 0.509) between the two groups. Overall stoma-related complications occurred in 27 (32.9%) patients. Stoma-related complications occurred more frequently in the ileostomy group (16/33 vs. 11/49 patients, p = 0.014). High output stoma (6 patients) and irritation (5 patients) occurred more frequently in the ileostomy group. Conclusions: Palliative colostomy is superior to ileostomy due to fewer stoma-related complications. When ileostomy is required, aggressive interventions for high output stomas should be implemented.

    Objectives: Previously, adjuvant chemotherapy using oxaliplatin was a standard treatment for patients with node-positive colorectal cancer (CRC) who underwent curative surgery. The factor predicting adverse events and therapeutic effect have not yet been established. Methods: A retrospective cohort of 42 patients diagnosed with stage III CRC between April 2009 and March 2013 in our institution were included in this study. The indicators of host nutritional status were body weight (BW), body mass index (BMI), serum albumin, Onodera's prognostic nutritional index (OPNI), and Glasgow Prognostic Score (GPS). The indicators of host immunocompetence was total lymphocyte counts, total neutrophil counts, granulocytes/lymphocytes ratio (G/L ratio). Results: The overall recurrence rate was 26.1%. Patients who had a recurrence were more likely to be older. The recurrence was not associated with type of regimen or adverse events. The cases with a few cumulative doses and relative dose intensity of oxaliplatin experienced significantly more recurrence. Nutritional status indicators, such as the serum albumin level, OPNI, and the modified Glasgow prognostic score (mGPS) were associated with the adjuvant chemotherapy outcome. Our study results indicated worse nutritional status induced worse disease-free survival (DFS) and more recurrence. Conclusion: The host's nutritional status associated with outcomes in stage III CRC patients.

    Objectives: Raman spectroscopy yields precise information, not only regarding the secondary structure of proteins but also regarding the discrimination between normal and malignant tissues. There is, however, no standard measurement method. We evaluated the use of a miniaturized, handheld, all-in-one Raman spectrometer with a 1064-nm laser excitation source for the diagnosis of colorectal cancer. The ultimate goal is real-time, in vivo diagnosis. Methods: Tissue samples were obtained from 20 patients who underwent surgery for colorectal cancer. The samples were irradiated with the portable Progeny™ Raman spectrometer, with which the Raman spectra were also obtained. We searched for characteristic Raman shifts and examined whether these shifts could distinguish the cancer tissues. To improve accuracy, we divided the spectra into 100 cm−1 bands and applied principal component analysis (PCA) to each range. We evaluated the contribution of each range for cancer discrimination. Results: Intensities at 1261 and 1427 cm−1 differed significantly between the normal tissues and cancer tissues, but these did not efficiently discriminate the cancer tissues. However, we were able to identify the characteristic spectral range in fingerprint regions; accuracy was 85.1%. Conclusions: Use of the all-in-one type Raman spectrometer can efficiently discriminate colorectal cancer, not on the basis of the intensities at 1261 and 1427 cm−1 but rather on the basis of PCA. Thus, Raman spectroscopy performed using a handheld device has potential to become a clinically powerful tool for producing high-quality data, obtaining highly reproducible measurements, and thus accurately diagnosing colorectal cancer.

    Objectives: Restorative proctocolectomy and ileal pouch-anal anastomosis is frequently performed in patients with ulcerative colitis and factors suspected of increasing the risk of postoperative infectious complications. Using a three-stage approach may result in improvement in overall outcomes, because this leads to improvement in nutritional status and reduction of immunosuppressive doses. However, the influence of preoperative nutritional status on postoperative infectious complications after this procedure has not been examined. The aim of this study was to clarify the potential associations between nutritional status and postoperative infectious complications in patients with ulcerative colitis undergoing proctectomy with ileal pouch-anal anastomosis. Methods: The records of 110 patients who had undergone proctectomy with ileal pouch-anal anastomosis from January 2000 to March 2018 in Mie University and met the eligibility criteria were reviewed and possible associations between postoperative infectious complications and clinical factors were assessed. Results: Of the remaining 110 patients, 18 (16.4%) had developed postoperative infectious complications. Multivariate analysis revealed that operative bleeding ≥270 g and prognostic nutritional index <47 were significant predictors of postoperative infectious complications (P = 0.033, 0.0076, respectively). Various variables associated with immunosuppressives before ileal pouch-anal anastomosis were not associated with postoperative infectious complications. Conclusions: Our findings suggest that immunosuppressives have no association with postoperative infectious complications, whereas a poor prognostic nutritional index may be a significant predictor of postoperative infectious complications in patients with ulcerative colitis undergoing proctectomy with ileal pouch-anal anastomosis.
