Abstract
BACKGROUND Early laparoscopic cholecystectomy (ELC) is the standard treatment for acute cholecystitis (AC). However, predicting the difficulty of this procedure remains challenging. The present study aimed to develop an improved prediction model for surgical difficulty during ELC, surpassing the current Tokyo Guidelines 2018 (TG18) grading system. METHODS We analyzed data from 201 consecutive patients who underwent ELC for AC between 2019 and 2021. Surgical difficulty was defined as the failure to achieve the critical view of safety (non-CVS). We developed a scoring system by conducting multivariate analysis on demographics, symptoms, laboratory data, and radiographic findings. The predictive accuracy of our scoring system was compared to that of the TG18 grading system (Grade I vs. Grade II/III). RESULTS Through multivariate logistic regression analysis, a novel scoring system was formulated. This system incorporated preoperative C-reactive protein (CRP) values (≥5: 1 pt, ≥10: 2 pts, ≥15: 3 pts) and TG18 grading score (duration >72 h: 1 pt, image criteria for Grade II AC: 1 pt). Our model, a cutoff score of ≥3, exhibited a significantly elevated area under the curve (AUC) of 0.721 compared to the TG18 grading system alone (AUC 0.609) (p = 0.001). CONCLUSION Combining preoperative CRP values with TG18 grading criteria can enhance the accuracy of predicting intraoperative difficulty in ELC for AC.

Abstract
BACKGROUND Indocyanine green fluorescence imaging (ICG-FI) has been reported to be useful in reducing the incidence of anastomotic leakage (AL) in colectomy. This study aimed to investigate the correlation between the required time for ICG fluorescence emission and AL in left-sided colon and rectal cancer surgery using the double-stapling technique (DST) anastomosis. METHODS This retrospective study included 217 patients with colorectal cancer who underwent left-sided colon and rectal surgery using ICG-FI-based perfusion assessment at our department between November 2018 and July 2022. We recorded the time required to achieve maximum fluorescence emission after ICG systemic injection and assessed its correlation with the occurrence of AL. RESULTS Among 217 patients, AL occurred in 21 patients (9.7%). The median time from ICG administration to maximum fluorescence emission was 32 s (range 25-58 s) in the AL group and 28 s (range 10-45 s) in the non-AL group (p < 0.001). The cut-off value for the presence of AL obtained from the ROC curve was 31 s. In 58 patients with a required time for ICG fluorescence of 31 s or longer, the following risk factors for AL were identified: low preoperative albumin [3.4 mg/dl (range 2.6-4.4) vs. 3.9 mg/dl (range 2.6-4.9), p = 0.016], absence of preoperative mechanical bowel preparation (53.8% vs. 91.1%, p = 0.005), obstructive tumor (61.5% vs. 17.8%, p = 0.004), and larger tumor diameter [65 mm (range 40-90) vs. 35 mm (range 4.0-100), p < 0.001]. CONCLUSION The time required for ICG fluorescence emission was associated with AL.

Abstract
BACKGROUND Early laparoscopic cholecystectomy (ELC) for acute cholecystitis (AC) poses multiple challenges. The Tokyo Guidelines 2018 (TG18) eliminated the time limit (< 72 h) and expanded the surgical indication to severe AC. This study aimed to evaluate the clinical outcomes of ELC for AC following the TG18 in a single high-volume center. METHODS From 2019 to 2021, we managed all AC patients with a TG18 flowchart and prospectively enrolled those who underwent ELC within 7 days of symptom onset. The primary outcome was overall morbidity, with a comparison between mild (Grade I) and moderate/severe (Grade II/III) AC. RESULTS During the study period, 201 patients underwent ELC was for Grade I (56.2%), II (40.3%), and III (3.5%) ACs. Mean age was 69 ± 15.2 years and time to surgery from symptom onset was 0 (12.9%), 1-3 (66.7%), and 4-7 days (20.4%). Mean operative time and blood loss were 118.9 ± 42.7 min and 57.8 ± 99.4 mL, respectively. The critical view of safety (CVS) was achieved in 76.1% of patients, and bailout procedures were performed in 21.4%. There were no open conversions or bile duct injuries. Major morbidities (Clavien-Dindo classification ≥ IIIa) were observed in 5.5% of cases and mortality in 0.5%. Comparing Grades II/III to Grade I, operative time was longer (112.3 vs. 127.3 min, p = 0.014), blood loss was higher (40.3 vs. 80.1 mL, p = 0.005), the CVS rate was lower (83.2 vs. 67.0%, p = 0.012), and the major morbidity rate was higher (1.8 vs. 10.2%, p = 0.012). In the subgroup analysis of Grade II/III, there were no significant differences in major morbidities (p = 0.288) between the two groups (0-3 vs. 4-7 days). CONCLUSION ELC for AC following TG18 is feasible with low morbidity rates. However, ELC for Grade II/III ACs remains challenging, and surgeons must carefully assess intraoperative difficulties and surgical risks before proceeding.

Abstract
BACKGROUND In a Phase 3 international clinical trial (VIALE-C), venetoclax plus low-dose cytarabine improved the response rate and overall survival versus placebo plus low-dose cytarabine in patients with newly diagnosed acute myeloid leukemia who were ineligible for intensive chemotherapy. After the enrollment period of VIALE-C ended, we conducted an expanded access study to provide preapproval access to venetoclax in combination with low-dose cytarabine in Japan. METHODS Previously, untreated patients with acute myeloid leukemia who were ineligible for intensive chemotherapy were enrolled according to the VIALE-C criteria. Patients received venetoclax (600 mg, Days 1-28, 4-day ramp-up in Cycle 1) in 28-day cycles and low-dose cytarabine (20 mg/m2, Days 1-10). All patients took tumor lysis syndrome prophylactic agents and hydration. Safety endpoints were assessed. RESULTS Fourteen patients were enrolled in this study. The median age was 77.5 years (range = 61-84), with 78.6% over 75 years old. The most common grade ≥ 3 treatment-emergent adverse event was neutropenia (57.1%). Febrile neutropenia was the most frequent serious adverse event (21.4%). One patient developed treatment-related acute kidney injury, leading to discontinuation of treatment. Two patients died because of cardiac failure and disease progression that were judged not related to study treatment. No patients developed tumor lysis syndrome. CONCLUSIONS The safety outcomes were similar to those in VIALE-C without new safety signals and were well managed with standard medical care. In clinical practice, more patients with severe background disease are expected, in comparison with in VIALE-C, suggesting that it is important to carefully manage and prevent adverse events.

Abstract
BACKGROUND A growing body of evidence suggests that non-viral hepatocellular carcinoma (HCC) might benefit less from immunotherapy. MATERIALS AND METHODS We carried out a retrospective analysis of prospectively collected data from consecutive patients with non-viral advanced HCC, treated with atezolizumab plus bevacizumab, lenvatinib, or sorafenib, in 36 centers in 4 countries (Italy, Japan, Republic of Korea, and UK). The primary endpoint was overall survival (OS) with atezolizumab plus bevacizumab versus lenvatinib. Secondary endpoints were progression-free survival (PFS) with atezolizumab plus bevacizumab versus lenvatinib, and OS and PFS with atezolizumab plus bevacizumab versus sorafenib. For the primary and secondary endpoints, we carried out the analysis on the whole population first, and then we divided the cohort into two groups: non-alcoholic fatty liver disease (NAFLD)/non-alcoholic steatohepatitis (NASH) population and non-NAFLD/NASH population. RESULTS One hundred and ninety patients received atezolizumab plus bevacizumab, 569 patients received lenvatinib, and 210 patients received sorafenib. In the whole population, multivariate analysis showed that treatment with lenvatinib was associated with a longer OS [hazard ratio (HR) 0.65; 95% confidence interval (CI) 0.44-0.95; P = 0.0268] and PFS (HR 0.67; 95% CI 0.51-0.86; P = 0.002) compared to atezolizumab plus bevacizumab. In the NAFLD/NASH population, multivariate analysis confirmed that lenvatinib treatment was associated with a longer OS (HR 0.46; 95% CI 0.26-0.84; P = 0.0110) and PFS (HR 0.55; 95% CI 0.38-0.82; P = 0.031) compared to atezolizumab plus bevacizumab. In the subgroup of non-NAFLD/NASH patients, no difference in OS or PFS was observed between patients treated with lenvatinib and those treated with atezolizumab plus bevacizumab. All these results were confirmed following propensity score matching analysis. By comparing patients receiving atezolizumab plus bevacizumab versus sorafenib, no statistically significant difference in survival was observed. CONCLUSIONS The present analysis conducted on a large number of advanced non-viral HCC patients showed for the first time that treatment with lenvatinib is associated with a significant survival benefit compared to atezolizumab plus bevacizumab, in particular in patients with NAFLD/NASH-related HCC.

Abstract
A 66-year-old man was referred to our department with the diagnosis of ascending colon cancer. He was undergoing dialysis for chronic renal failure due to diabetic nephropathy. Laparoscopic ileocecal resection was planned for the ascending colon cancer, but the procedure was converted to laparotomy owing to intraoperative bleeding. The patient was discharged from the hospital after 7 days. On the 14th postoperative day, the patient presented with purulent drainage from the wound and fever and was diagnosed to have a minor anastomotic leak. The suture of the anterior sheath was exposed in part of the wound. The patient's general condition was stable, and conservative treatment was planned. However, when he coughed, the wound separated and the intestine prolapsed, and emergency surgery was performed. Intraoperative findings showed leakage of intestinal fluid from the anastomotic border, and we diagnosed delayed suture failure. We present a rare case of delayed anastomotic leakage in a hemodialysis patient.

Abstract
A 78-year-old male presented with a positive fecal occult blood test. Rectal cancer was detected during lower gastrointestinal endoscopy, and further investigations led to a diagnosis of cT1N0M0 cStage I (UICC classification, 8th edition). Preoperative contrast-enhanced computed tomography (CT) showed that the patient also had Leriche syndrome, which is associated with reduced blood flow to the rectum that may result in ischemic anastomosis during rectal cancer surgery with anastomotic reconstruction. The inferior epigastric arteries often function as collateral pathways to the lower limbs in patients with Leriche syndrome; therefore, care is needed to avoid vascular damage during trocar insertion when performing laparoscopic surgeries. We herein described a case of safe laparoscopic low anterior resection in a rectal cancer patient with Leriche syndrome using vascular architecture images obtained by preoperative CT angiography.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) treatment remains a big challenge in the field of oncology. The liver disease (viral or not viral) underlying HCC turned out to be crucial in determining the biologic behavior of the tumor, including its response to treatment. The aim of this analysis was to investigate the role of the etiology of the underlying liver disease in survival outcomes. PATIENTS AND METHODS We conducted a multicenter retrospective study on a large cohort of patients treated with lenvatinib as first-line therapy for advanced HCC from both Eastern and Western institutions. Univariate and multivariate analyses were performed. RESULTS Among the 1232 lenvatinib-treated HCC patients, 453 (36.8%) were hepatitis C virus positive, 268 hepatitis B virus positive (21.8%), 236 nonalcoholic steatohepatitis (NASH) correlate (19.2%) and 275 had other etiologies (22.3%). The median progression-free survival (mPFS) was 6.2 months [95% confidence interval (CI) 5.9-6.7 months] and the median overall survival (mOS) was 15.8 months (95% CI 14.9-17.2 months). In the univariate analysis for OS NASH-HCC was associated with longer mOS [22.2 versus 15.1 months; hazard ratio (HR) 0.69; 95% CI 0.56-0.85; P = 0.0006]. In the univariate analysis for PFS NASH-HCC was associated with longer mPFS (7.5 versus 6.5 months; HR 0.84; 95% CI 0.71-0.99; P = 0.0436). The multivariate analysis confirmed NASH-HCC (HR 0.64; 95% CI 0.48-0.86; P = 0.0028) as an independent prognostic factor for OS, along with albumin-bilirubin (ALBI) grade, extrahepatic spread, neutrophil-to-lymphocyte ratio, portal vein thrombosis, Eastern Cooperative Oncology Group (ECOG) performance status and alpha-fetoprotein. An interaction test was performed between sorafenib and lenvatinib cohorts and the results highlighted the positive predictive role of NASH in favor of the lenvatinib arm (P = 0.0047). CONCLUSION NASH has been identified as an independent prognostic factor in a large cohort of patients with advanced HCC treated with lenvatinib, thereby suggesting the role of the etiology in the selection of patients for tyrosine kinase treatment. If validated, this result could provide new insights useful to improve the management of these patients.

Abstract
This case involved a 63-year-old man. He underwent robot-assisted radical prostatectomy (RARP) for prostate cancer. One year after the operation, he consulted our hospital about left inguinal swelling. Under a diagnosis of a left external inguinal hernia, transabdominal preperitoneal repair (TAPP) was performed under general anesthesia. The inside of the hernia orifice had been damaged by the RARP, and the resultant fibrosis was so marked that it was difficult to dissect the preperitoneal space. Furthermore, an external iliac vein injury occurred during the operation. The bleeding was controlled, and we used laparoscopic continuous non-absorbable sutures to repair the external iliac vein injury. The number of TAPP procedures performed after radical prostatectomy has been increasing in recent years, but dissecting the preperitoneal space inside a hernia orifice is difficult. Although external iliac vein injuries are rare complications of TAPP procedures, they can be laparoscopically repaired.

Abstract
A 72-year-old woman underwent sigmoid colon resection plus D2 lymph node dissection in 2008, with additional resection after endoscopic mucosal resection(EMR). Histopathological examination revealed only atypical ducts in the EMR scar, with no invasion below the submucosa. No lymphatic, venous, or nerve invasions were confirmed, and oral and anal stumps and lymph node metastases were negative. She was followed up for 5 years after the surgery, and no recurrence was detected. In 2018, she visited our hospital with the chief complaint of diarrhea and constipation. Colonoscopy revealed a circumferential lesion around the anastomosis. She underwent laparoscopic low anterior resection for suspected anastomotic recurrence, which was confirmed by histopathological diagnosis. The anastomotic recurrence 10 years after surgery for SM cancer of the colon with negative lymph node metastasis and vascular factor was extremely rare. We recognized the importance of surveillance 5 years after surgery.

Abstract
BACKGROUND The authors conducted a systematic review and meta-analysis to provide a summary estimate of the association between oral health and academic performance. TYPES OF STUDIES REVIEWED The authors conducted a systematic search of PubMed, Embase, and Google Scholar for studies on oral health, school absence, and academic achievement published in English from January 1945 through December 2017. Exposures included subjectively or objectively measured caries, oral pain, and periodontitis. Outcomes included school absence and school achievement. RESULTS The authors screened a total of 2,041 studies, from which they extracted data from 14 studies of 139,989 children (12 cross-sectional studies, 1 case-control study, and 1 longitudinal study). Five studies had school absence as the primary outcome, and 7 studies had student achievement as the primary outcome. Three studies included both outcomes. The authors found no studies for periodontitis. The average modified Newcastle-Ottawa Scale score was 3.93. The authors rated 10 studies as having a low risk of bias and 4 as having a high risk of bias. Qualitative synthesis suggested that poor oral health may have negative effects on student absenteeism and achievement, but study quality was highly variable. Results from meta-analyses indicated that poor oral health was significantly associated with increased odds of poor academic performance (pooled odds ratio, 1.52; 95% confidence interval, 1.20 to 1.83) and absenteeism (pooled odds ratio, 1.43; 95% confidence interval, 1.24 to 1.63). CONCLUSIONS AND PRACTICAL IMPLICATIONS Increased focus on the broader implications of improvements in oral health for children, such as educational or socioemotional development, is of further interest to practicing dentists owing to the greater connection between oral health and general health. The authors of this study found that caries or tooth pain had a negative association with academic achievement and school absenteeism. However, study quality was limited by inconsistent exposure and outcome definitions and a predominance of cross-sectional designs. Thus, causal conclusions are not supported.

Abstract
BACKGROUND Antimicrobial resistance (AMR) is now recognized as a major threat to public health, and surveillance of AMR is essential for successful containment. In 2000, Japan Nosocomial Infections Surveillance (JANIS) Clinical Laboratory (CL) division has been launched as a voluntary AMR surveillance funded by the Ministry of Health, Labour and Welfare and managed by the National Institute of Infectious Diseases. In this study, we aimed to propose a model of sustainable national AMR surveillance which provides not only national AMR surveillance reports but also benchmarking reports to each hospital to facilitate infection control practices. METHODS JANIS CL division collects comprehensive specimen-based data complies with JANIS data format from participating hospitals each month. It had targeted only blood and cerebrospinal fluid samples but was expanded to all types of specimens in 2007 at revision of JANIS. The JANIS system interprets the antimicrobial susceptibility according to the same criteria and conducts removal of duplicates to allow accurate comparison between hospitals. Monthly feedback reports are created automatically within 48 h, while quarterly and annual reports are generated after data validation. RESULTS At the beginning, 468 hospitals were enrolled in the JANIS CL division, but the number of hospitals that submitted data decreased to 210 (45%) in 2006. After surveillance revision in 2007, annual recruitment of hospitals was initiated and as of 2015, 1475 hospitals participated, and 1461 (99%) of them submitted data throughout the year. Nationwide surveillance data collected over the past decade revealed that the prevalence of methicillin-resistant Staphylococcus aureus has decreased since 2008, and that its prevalence is higher in the western part of Japan, where the number of hospitals per capita is higher than in the eastern part. CONCLUSIONS JANIS CL division serves a model of sustainable national AMR surveillance system. Comprehensive data for all specimens promotes understanding of the sampling frequency and prevalence of AMR. As a well-established system for providing rich information to guide action both locally and nationally, JANIS may also be utilized for sharing AMR data globally.

Abstract
Frequent use of broad-spectrum antimicrobial classes has been reported in Japan; however, little is known about the long-term trend of national antimicrobial consumption, and that of individual agents. This study analyzed the national sales data of systemic antimicrobials from 2004 to 2016, derived from the IMS Japan Pharmaceutical Market database, to assess the consumption patterns of antimicrobial classes and agents in Japan. The number of defined daily doses per 1000 inhabitants per day (DID) was calculated for each antimicrobial agent. During the last 13 years, total antimicrobial consumption fluctuated by only 5% around the average of 14.41 DID. In 2016, the most used class was macrolides (32%), followed by cephalosporins (28%) and fluoroquinolones (19%). Oral agents comprised a large proportion (93%) of antimicrobial consumption. The most used agent, clarithromycin, accounted for 25% of all oral compounds used in 2016. The consumption of oral agents with high bioavailability, such as fluoroquinolones, amoxicillin, and sulfamethoxazole/trimethoprim increased, whereas that of cephalosporins decreased. In 2016, ceftriaxone was the most consumed parenteral agent, followed by cefazolin. The consumption of parenteral agents increased after 2009 when high-dose regimens of piperacillin/tazobactam, meropenem, and ampicillin/sulbactam were approved by the health insurance system. National antimicrobial consumption has been stable over the last 13 years. Moreover, shifts in the use of agents with high bioavailability and those approved for high-dose regimens were observed. However, the increased use of broad-spectrum agents is worrisome. A multifaceted approach is required to reduce overall antimicrobial consumption.

Abstract
Purpose For locally advanced pathological T4 (pT4) colon cancer, the safety and feasibility of laparoscopic procedures remain controversial. Therefore, this study aimed to assess short-term and long-term outcomes and to identify the prognostic factors in laparoscopic surgery for pT4 colon cancer. Methods The study group included 130 patients who underwent laparoscopic radical resection for pT4 colon and rectosigmoid cancer from January 2004 through December 2012. The short-term outcomes, long-term outcomes, and prognostic factors in pT4 colon cancer were analyzed. Results The median operative time was 205 min, with a median blood loss of 10 ml. The conversion rate was 3.8%, and 13 patients (10.0%) had postoperative complications. The radial resection margin was positive in 1 patient (0.8%). The median follow-up time was 73 months. The 5-year overall survival (OS) and recurrence-free survival (RFS) were 77.2 and 63.5%, respectively. On a multivariate analysis, a male sex [hazard ratio (HR) 3.09, p < 0.001], lymph node ratio ≥ 0.06 (HR 2.35, p = 0.021), tumor diameter < 38 mm (HR 2.57, p = 0.007), and right-sided colon cancer (HR 2.11, p = 0.047) were significantly related to a poor OS. Conclusions These results suggest that laparoscopic surgery for pT4 colon cancer is safe and feasible, and the oncological outcomes are acceptable. Based on the present findings, select patients with locally advanced colon cancer should not be excluded from laparoscopic surgery.

Abstract
The patient was a 52-year-old man who had a positive fecal occult-blood test on a medical check-upi n April 2015 and was referred to our hospital in June. Detailed preoperative examinations resulted in a diagnosis of cancer of the lower rectum, multiple liver metastases, and clinical Stage IV . A biopsy showed moderately differentiated tubular adenocarcinoma. All-RAS was wild type, and the patient was asymptomatic. Unresectable advanced rectal cancer was diagnosed, and the patient was scheduled to receive systemic chemotherapy. The patient received a total of 16 courses of combination chemotherapy with 5- fluorouracil, Leucovorin, and oxaliplatin(FOLFOX)plus panitumumab, starting in October 2015. In July 2016, Colonoscopy showed scar findings at the site of the primary rectal cancer lesion. A biopsy revealed no cancer cells. It was difficult to identify the primary lesion on computed tomography, and there was no evidence of clinically significant lymphadenopathy. Positronemission tomography and computed tomography showed shrinkage of the liver metastases, with no accumulation of tracer in the primary lesion or lymph nodes. The primary lesion had a clinical complete response(CR), and the metastatic lesions had a clinical partial response(PR). In October 2016, laparoscopic partial hepatectomy was performed to treat the liver metastases. Histologic examination showed that the liver metastases were from rectal cancer. It is currently under observation.

Abstract
The mainstay of treatment for metastatic colorectal cancer is surgery. Therefore, colorectal cancer metastasis is distinctive, compared to other cancer types in which chemotherapy is the main treatment. Initially, Japan experienced medical druglag compared with western countries. However, the use of oxaliplatin for unresectable recurrent metastatic colorectal cancer became available in Japan, as well as in western countries, in 2005. We have since shifted chemotherapeutic regimens from monotherapy to combination therapy with molecular targeted agents. The combination therapy has rapidly become a standard therapy for unresectable metastatic colorectal cancer, and prognosis has dramatically increased for patients with this condition. Herein, we describe the treatment of liver metastasis of colorectal cancer, and surgery and adjuvant or neoadjuvant therapy options for resectable cancer. Furthermore, we focus on conversion therapy for unresectable cancer.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) bacteremia is one of the commonest and most life-threatening of all infectious diseases. The morbidity and mortality rates associated with MRSA bacteremia are higher than those associated with bacteremia caused by other pathogens. A common guideline in MRSA bacteremia treatment is to confirm bacteremia clearance through additional blood cultures 2-4 days after initial positive cultures and as needed thereafter. However, no study has presented statistical evidence of how and to what extent confirming a negative follow-up blood culture impacts clinical outcome. We present this evidence for the first time, by combining clinical microbiological data of blood cultures and the DPC administrative claims database; both had been systematically accumulated through routine medical care in hospitals. We used electronic medical records to investigate the clinical background and infection source in detail. By analyzing data from a university hospital, we revealed how survival curves change when a negative follow-up blood culture is confirmed. We also demonstrated confirmation of a negative culture is significantly associated with clinical outcomes: there was a more than three-fold increase in mortality risk (after adjusting for clinical background) if a negative blood culture was not confirmed within 14 days of the initial positive blood culture. Although we used data from only one university hospital, our novel approach and results will be a basis for future studies in several hospitals in Japan to provide statistical evidence of the clinical importance of confirming a negative follow-up blood culture in bacteremia patients, including those with MRSA infections.

Abstract
INTRODUCTION Despite the availability of various anastomosis techniques, postoperative anastomotic complications such as anastomosis failure and bleeding develop in some patients. Automatic suturing devices have been widely used for gastrointestinal anastomosis. However, overly thick or thin tissue, displacement of tissue, and the creation of a staple-on-staple site may lead to incomplete staple formation. These factors are considered to be related to postoperative complications such as anastomosis failure. METHODS The iDrive™ Ultra Powered Stapling System was used to fire the automatic suturing device. Two types of automatic suturing devices were employed: (i) the Endo GIA™ Reinforced Reload with Tri-Staple™ Technology with a cartridge with the reinforcement material Neoveil™; and (ii) the Endo GIA™ with Tri-Staple™ Technology with no reinforcement material. Stapling was performed using a two-stage crossing approach to make a staple-on-staple site. RESULTS The rates of complete formation with the Endo GIA™ with Tri-Staple™ Technology were 95.6 ± 0.6% for stomach tissue and 95.6 ± 2.3% for colon tissue, which is thinner than stomach tissue. In contrast, the rates of complete formation with the Endo GIA™ Reinforced Reload with Tri-Staple™ Technology were 99.3 ± 1.27% for stomach tissue and 100.0 ± 0.0% for colon tissue. CONCLUSION Our results showed that the Endo GIA™ Reinforced Reload with Tri-Staple™ Technology had higher rates of complete staple formation than the Endo GIA™ with Tri-Staple™ Technology, irrespective of tissue thickness and the presence of a staple-on-staple site.

Abstract
Background Gastrointestinal anastomosis remains associated with a considerable burden of morbidity and, in some cases, mortality. Functional end-to-end anastomosis, whilst extremely efficient, is vulnerable to increased intestinal pressure in the immediate postoperative period, which may predispose to development of anastomotic leakage or bleeding. Therefore, there is a requirement for new techniques that facilitate safe and efficacious anastomotic procedures. Materials and methods This study examined the clinical application of functional end-to-end anastomosis with a stapler that automatically applies a bioabsorbable polyglycolic acid sheet (Endo GIA™ Reinforced Reload with Tri-Staple™ Technology). A porcine model was used to examine functional end-to-end anastomosis with and without application of a bioabsorbable polyglycolic acid sheet. As the crotch of the anastomosis is considered the weakest point, a probe was used to test the integrity of these anastomoses. Furthermore, we performed functional end-to-end anastomosis using the Endo GIA™ Reinforced stapler in a clinical series of 20 patients undergoing gastrointestinal tract resection. In all cases, functional end-to-end anastomosis was performed without suture reinforcement. Results Small intestine anastomoses in the animal study exhibited no weakness at the crotch of the anastomosis, as tested with a probe, suggesting an increased resiliency to conventional complications of functional end-to-end anastomosis. In the clinical population, no postoperative complications were noted. No adhesive intestinal obstruction was noted. Conclusion Sutureless functional end-to-end anastomosis using the Endo GIA™ Reinforced appears to be safe, efficacious, and straightforward. Reinforcement of the crotch site with a bioabsorbable polyglycolic acid sheet appears to mitigate conventional problems with crotch-site vulnerability. Functional end-to-end anastomosis is safe with the Endo GIA™ Reinforced stapler. Conventional functional end-to-end anastomosis requires suture reinforcement. The Endo GIA™ Reinforced allows sutureless anastomosis by creating staple planes.

Abstract
Backgroud The main advantage of laparoscopic surgery is that it is minimally invasive because of the use of small incisions. An approach using small incisions offers many benefits including attenuation of surgical wound pain. However, the presence of postoperative pain may undermine the advantages of laparoscopic surgery as a minimally invasive technique. In addition, perioperative pain management is an important factor affecting recovery after surgery. This study investigated the usefulness of a multimodal approach to postoperative pain management with acetaminophen as a baseline analgesic after minimally invasive laparoscopic colorectal surgery. Materials and methods The study included 40 patients who underwent laparoscopic colorectal surgery for colorectal cancer. 20 patients received acetaminophen as a baseline analgesic for postoperative pain management and 20 received epidural anesthesia. Results The urethral catheter could be removed earlier in the acetaminophen group (2.1 ± 0.22 days postoperatively) compared with the epidural group (4.1 ± 0.45days postoperatively). The frequencies of vertigo were significantly lower in the acetaminophen than epidural group (10.0% and 45.0%, respectively). The frequencies of the use of analgesics on an as-needed basis for postoperative pain relief as well as the variabilities in these frequencies, although not significantly different between the acetaminophen and epidural groups, were lower in the acetaminophen group than the epidural group. Conclusion We herein demonstrated that postoperative pain management with acetaminophen as a baseline analgesic, and without the use of epidural anesthesia, is a safe and useful analgesic modality. Multimodal analgesia with acetaminophen was effective after laparoscopic surgery. Adverse events were less frequent with acetaminophen than epidural anesthesia. Frequency and variability of rescue use were lower with acetaminophen than epidural.

Abstract
BACKGROUND Neoadjuvant chemoradiotherapy (NCRT) for advanced rectal cancer (RC) is a well-evidenced therapy; however, some RC patients have no therapeutic response. Patient selection for NCRT so that non-responsive patients are excluded has been subjective. To date, no molecular markers indicating radiation sensitivity have been reported. METHODS We irradiated six colorectal cancer (CRC) cell lines and identified HCT116 cells as radiation-sensitive and HCT15 and DLD-1 cells as radiation resistant. Using a microarray, we selected candidate radiation sensitivity marker genes by choosing genes whose expression was consistent with a radiation-resistant or sensitive cell phenotype. RESULTS Among candidate genes, cellular retinol binding protein 1 (CRBP1) was of particular interest because it was not only induced in HCT116 cells by tentative 10 Gy radiation treatments, but also its expression was increased in HCT116-derived radiation-resistant cells vs parental cells. Forced expression of CRBP1 decreased the viability of both HCT15 and DLD-1 cells in response to radiation therapy. We also confirmed that CRBP1 was epigenetically silenced by hypermethylation of its promoter DNA, and that the quantitative methylation value of CRBP1 significantly correlated with histological response in RC patients with NCRT (P=0.031). CONCLUSIONS Our study identified CRBP1 as a radiation-sensitive predictor in RC.

Abstract
PURPOSE Abdominoperineal resection (APR) of advanced lower rectal cancer carries a high incidence of perineal wound infection. The aim of this study was to retrospectively evaluate risk factors for perineal wound infection after APR. METHODS The study group comprised 154 patients who underwent APR for advanced lower rectal cancer in our department from January 1990 through December 2012. The following 15 variables were studied as potential risk factors for perineal wound infection: sex, age, body-mass index, American Society of Anesthesiologists score, diabetes mellitus, preoperative albumin level, preoperative hemoglobin level, neoadjuvant chemoradiotherapy(NCRT), surgical procedure (open surgery vs. laparoscopic surgery), operation time, bleeding volume, intraoperative transfusion, tumor diameter, invasion depth, and histopathological stage. RESULTS Among the 154 patients, 30 (19%) had perineal wound infection. Univariate analysis showed that a hemoglobin level of ≤11 g/dL (p = 0.001) and NCRT (p = 0.001) were significantly related to perineal wound infection. On multivariate analysis including the preoperative albumin level (≤3.5 g/dL) in addition to the above 2 variables, neoadjuvant chemoradiotherapy (NCRT) was the only independent risk factor for perineal wound infection. Perineal wound infection developed in 31% of patients who received NCRT, as compared with 10% of patients who did not receive NCRT. The relative risk of perineal infection in the former group was 4.092 as compared with the latter group (p = 0.0002). CONCLUSIONS NCRT is a risk factor for perineal wound infection after APR in patients with advanced lower rectal cancer.

Abstract
INTRODUCTION Laparoscopic surgery is widely used for the treatment of colorectal cancer, but it is often associated with postoperative anastomotic complications. Generally, gastrointestinal anastomosis for colorectal surgery is performed using mechanical anastomosis with a double stapling technique. Using the automatic suture device with bioabsorbable polyglycolic acid (PGA) felt is expected to adequately reinforce staple lines on fragile tissue, helping to prevent anastomotic complications, including leakage. METHODS This study included 17 patients who underwent laparoscopic surgery after a diagnosis of colorectal cancer. The rectosigmoidal colon was resected toward the dentate line with a novel automatic PGA-felt suture device. RESULTS None of the patients had any postoperative bleeding, and none developed grade III or higher postoperative complications based on the Clavien-Dindo classification. When the sigmoid colon, rectosigmoid, or rectum was anastomosed, holding the excess portion of the PGA felt, stapled with the automatic PGA-felt suture device, allowed us to adequately maneuver the part of the colon or rectum to be anastomosed. With this technique, we could easily and safely insert and remove the automatic anastomotic device. When the lower rectum was resected in a planned, two-step operation, the orientation of the PGA felt helped to determine the direction in which the automatic suture device was to be inserted in the second step. Thus, the resected rectum could easily be stapled in a straight line. CONCLUSION The automatic PGA-felt suture device is safe and effective for colorectal resections and anastomoses.

Abstract
INTRODUCTION Clinical use of an adhesion barrier made of oxidized, regenerated cellulose, Interceed®, has been reported in the field of obstetrics and gynecology to help prevent adhesions between the peritoneum and the bowel in various types of operations. In gastrointestinal surgery, sodium hyaluronate/carboxymethylcellulose has been reported as an absorbable membrane to reduce postoperative adhesions. The present study was a prospective randomized controlled study to investigate the safety and usefulness of Interceed in laparoscopic colorectal surgery. METHODS We analyzed 99 patients who underwent laparoscopic colorectal surgery from 2013 to 2014. The patients were randomly allocated to the group that used Interceed (Interceed group) or the group that did not (Non-Interceed group). RESULTS Fifty cases used Interceed, and 49 cases did not. The incidence of adverse events was 12.0% in the Interceed group and 16.3% in the Non-Interceed group (P = 0.58). There were no significant differences, and no adhesive bowel obstructions were observed in the Interceed group. CONCLUSION We have shown that using Interceed in laparoscopic colorectal surgery is valid and technically safe.

Abstract
A 70-year-old woman had been aware of lower extremity weakness and anal discomfort for 3 years. A soft, elastic, palm-sized mass covered by a large amount of mucus was found protruding from the anus. Biopsy revealed a villous adenoma. On the basis of these results, a villous adenoma associated with electrolyte depletion syndrome was diagnosed. After electrolyte abnormalities were improved by fluid replacement therapy, laparoscopic abdominoperineal resection was performed. The surgically resected specimen was a circumferential villous tumor measuring 210 × 140 mm. The histopathological diagnosis was an intramucosal papillary adenocarcinoma. The patient recovered uneventfully after surgery, and the electrolyte abnormalities gradually improved. She was discharged on the 28th postoperative day. The electrolyte levels normalized about 3 months after surgery.

Abstract
3556 Background: To assess long-term clinical outcomes of neoadjuvant chemoradiotherapy (NCRT) of rectal cancer using concurrent irinotecan and S-1. Methods: One hundred and fifteen patients without distant metastases entered this phase II trial in cT3/T4 rectal cancer (n=104/11). Pelvic radiotherapy was given to 45 Gy in 25 fractions over 5 weeks with concurrent oral S-1 at 80 mg/m2 and intravenous irinotecan at 80 mg/m2 once weekly. Median follow-up term was 60 months (ranged from 20 to 96 months). Results: Adverse effect of Grade 3 was recognized in 7 patients (6%), and completion rate of this NCRT regimen was 87 %. All 115 patients (100%) could undergo R0 surgical resection. Twenty-eight patients (24%) demonstrated a pathologic complete response (ypCR). Local recurrence-free survival was 93%, disease-free survival (DFS) was 79%, and overall survival (OS) was 80%. By the multivariate proportional hazard model for DFS and OS, ypN2 was only remnant independent prognostic factor (P=0.0019 and P=0.0064, respectively). ypN2 was recognized in 9 patients (8%), and prognosis was extremely dismal (8 patients were recurred within 2 years). We again performed the multivariate analysis for 106 cases restricted to ypN0/1, which exhibited 85% of DFS, and both ypT and tumor portion were independent predictors (P=0.0065 and P=0.003, respectively). Combination of them could greatly enrich high risk patients for recurrence (P<0.0001), and dominant recurrences were uniquely found in lung. Conclusions: Novel NCRT regimen using S1/irinotecan demonstrated high response rates and excellent long-term survival, with acceptable adverse effects. ypN2 is a definitive indicator of dismal prognosis, and combination of ypT and tumor portion can identify high risk patients among the ypN0/1 patients.

Abstract
Surgery continues to play an important role in the curative treatment of gastrointestinal cancer. Recently, considerable progress has been made in chemotherapy and radiotherapy. In particular, chemotherapy with FOLFIRI and FOLFOX has prolonged survival in patients with colorectal cancer. Molecular-targeted agents have also enhanced the effectiveness of chemotherapy. However, radical resection offers the potential for a cure and is unsurpassed by any other treatments. Nonetheless, further improvement in survival is unlikely to be achieved by surgery alone. Studying how treatment regimens highly effective against unresectable or recurrent colorectal cancer can be adapted to patients with resectable disease is thus an important issue.

Abstract
A 57-year-old woman had undergone a modified radical mastectomy at another medical institute. Six years after the resection, a tumor was confirmed and diagnosed as a recurrent metastasis in the right margin of the breastbone. The patient underwent chemoradiation therapy at the other medical institute and was then transferred to our institute, where treatment was continued. Four years after the recurrence, chemotherapy with capecitabine was started. Over the past 6 years, the capecitabine dose has not been changed and no signs of local recurrence have been seen. The values of biomarkers are normal. No adverse events, such as hand-foot syndrome, have occurred. Early during the capecitabine treatment, grade 2 elevations in the patient's GOT and GPT values were observed. However, these values recovered immediately without supportive therapy. At present, this patient is continuing to receive capecitabine treatment without experiencing any serious adverse events.

Abstract
An outbreak of multidrug-resistant (MDR) Pseudomonas aeruginosa occurred in an acute care hospital in Japan, which lasted for more than three years. During January 2006 to June 2009, 59 hospitalised patients with MDR P. aeruginosa were mainly detected by urine culture in the first half, whereas isolation from respiratory tract samples became dominant in the latter half of the outbreak. Non-duplicate MDR P. aeruginosa isolates were available from 51 patients and all isolates were positive for bla(VIM-2). Pulsed-field gel electrophoresis (PFGE) analysis categorised the isolates into three major clusters; types A, B and C with eight, 19 and 21 isolates, respectively. The outbreak started with patients harbouring PFGE type A strains, followed by type B, and type C strains. Multivariate analysis demonstrated that patients with PFGE type C strains were more likely to be detected by respiratory tract samples (odds ratio: 11.87; 95% confidence interval: 1.21-116.86). Improved aseptic urethral catheter care controlled PFGE type A and type B strains and improvement in respiratory care procedures finally contained the transmission of PFGE type C strains.

Abstract
Sacrococcygeal teratoma is a relatively rare congenital retroperitoneal tumor in adults. The standard treatment is a complete tumor resection. This report describes the successful laparoscopic resection of a sacrococcygeal teratoma. The patient was a 27-year-old woman with a well-demarcated cystic mass, 6 cm in diameter, in the retroperitoneum overlying the anterior surface of the sacrum. The mass was resected laparoscopically. A histopathological examination showed a mature teratoma. The magnifying function of the laparoscope allowed an en bloc resection in the narrow pelvic cavity, without damaging the tumor. The aesthetic outcome was excellent. The patient remains relapse-free at 1 year 6 months after surgery.

Abstract
We report a case of possible retroperitoneal metastasis of breast cancer successfully treated with oral S-1 and cyclophosphamide therapy after docetaxel and cyclophosphamide (TC) therapy. A 57-year-old woman with a history of bilateral breast cancer showed an increase in tumor markers during treatment with oral anastrozole as postoperative adjuvant therapy 4 years after her second cancer surgery. After careful examination, the patient was diagnosed as having multiple bone metastases and her medication was changed to oral letrozole. After 3 months, the patient developed left back pain and was referred to our hospital. CT scanning showed an enhanced mass in the region from the left perirenal and posterior pararenal spaces to the left psoas major muscle and the anterior aspect of the left iliacus muscle, suggesting retroperitoneal metastasis. TC therapy was performed and, as a result, tumor markers decreased and the mass disappeared on CT imaging. After discontinuation of TC therapy, the tumor markers increased again, following which oral S-1 and cyclophosphamide therapy were administered, and the tumor markers decreased. At the time of this writing, the patient is still undergoing therapy, and no recurrence has been observed. We concluded that oral S-1 and cyclophosphamide therapy were useful in the present case and were associated with few adverse effects.

Abstract
A 26-year-old-woman was given a diagnosis of Wegener's granulomatosis and began treatment by both prednisolone and cyclophosphamide at another institution. She was then admitted to our hospital due to progressive multiple pulmonary nodules. A diagnosis of pulmonary metastases from bladder cancer was established with radiological and histological examinations obtained by transbronchial lung biopsy (TBLB) and transurethral resection of the bladder tumor (TUR-Bt). She had already received a total dose of 120 g of cyclophosphamide, which could be related to the development of bladder cancer. On detecting multiple pulmonary nodules in patients with Wegener's granulomatosis treated with cyclophosphamide, it is necessary to consider the possibility of pulmonary metastases form urinary bladder cancer.

Abstract
Many studies have shown the effects of chewing xylitol gum on mutans streptococci (MS) over short- and long-term periods in children; however, few studies have addressed long-term periods in adults. The objective of this investigation was to examine for 6 months the effects of chewing xylitol gum on MS in saliva and plaque in 127 adults (mean age 28.0 years). The participants were assigned to three groups according to gum type, in part taking preference for flavor into account and in part at random: xylitol (XYL), maltitol (MAL) and control (CR); 33, 34 and 27 subjects in each group, respectively, completed the trial. Daily gum use of the XYL and MAL groups was 7.9 and 7.1 g, respectively. MS levels, which declined significantly in saliva (p < 0.05) and plaque (p < 0.001) in the XYL group after 6 months, exhibited a significant increase in plaque in the MAL group (p < 0.001). Differences in relative changes of MS levels in plaque during the experimental period were significant between the XYL group and the CR (p < 0.05) and MAL groups (p < 0.001). Differences in relative change of amount of plaque during the experimental period were not statistically significant between the groups. The present study demonstrated that chewing xylitol gum for 6 months continued to inhibit the growth of mutans streptococci in adults.

Abstract
OBJECTIVE We investigated the association of lip pigmentation with smoking and melanin pigmentation in the gingiva. DESIGN Case-control study. SETTING Health check-up in an institute. SUBJECTS AND METHODS Photos of 213 males employed in an institution were assessed in terms of pigmentation in lip and gingiva. MAIN OUTCOME MEASURES Prevalence and scores of lip and gingival pigmentation and smoking status. RESULTS Among subjects displaying lip and gingival pigmentation, 73% and 87% respectively, were current smokers, whereas 33% and 27% of individuals lacking pigmentation were current smokers respectively. Odds ratios of current smoking relative to lip and gingival pigmentation were 5.6 (95% confidence interval: 2.8-11.1) and 17.0 (8.1-36.0) respectively. Daily consumption, duration of smoking and lifetime exposure exhibited significant correlation with scores of lip and gingival pigmentation (P<0.0001). Odds ratios increased in lip and gingival pigmentation upon exposure. In current smokers, scores of lip and gingival pigmentation demonstrated meaningful correlation (P<0.0001); moreover, 95% of participants with lip pigmentation were positive for gingival pigmentation. CONCLUSION These results indicated the presence of a striking association between smoking and pigmentation in the lip and gingiva, which was stronger with respect to gingival pigmentation. Health professionals could educate smokers, utilizing visible symptoms in the lip and gingiva.

Abstract
AIMS/BACKGROUND Our preliminary studies showed that estradiol suppresses hepatic carcinogenesis and fibrogenesis in animal models. Hepatic estrogen receptors (ERs) medicate estradiol action in the liver. This study was performed to assess possible implications of menopause and hepatic ER levels for the development of cirrhosis with hepatocellular carcinoma (HCC). METHODS One thousand, one hundred and ninety-nine consecutive HCC patients with hepatitis C virus (HCV)-related cirrhosis were divided into two groups, based on a menopausal age of 49 years. Liver tissues were obtained during surgical resection of HCC and metastatic liver tumor. RESULTS The proportion of females among the HCC subjects < or =49 years of age was significantly lower (15.0%) than was the proportion of females among subjects >49 years of age (29.8%). Univariate analysis showed that HCV-related cirrhotic patients who developed HCC were more likely to have low hepatic levels of ER and copper-zinc superoxide dismutase (CuZn-SOD) protein and a high hepatic level of a lipid peroxidation product, malondialdehyde (MDA). Logistic regression identified age greater than 49 years (odds ratio [OR]: 7.9, 95% confidence interval [CI]: 2.8-21.3), male sex (OR: 3.5, 95% CI: 1.3-10.2), a decreased ER level (OR: 16.8, 95% CI: 7.3-34.6), and an increased MDA (OR: 8.3, 95% CI: 2.8-24.0) as the variables independently associated with the development of HCC in HCV-infected patients with cirrhosis. ER level was significantly correlated with CuZn-SOD level (r=0.583) and was inversely proportional to MDA level (r=-0.553). The study also showed that ER levels in the cirrhotic livers from premenopausal females were significantly higher than in male cirrhotic livers. CONCLUSIONS These findings suggest that increased lipid peroxidation and impaired SOD function in the liver may be associated with decreased hepatic ER levels in HCV-infected patients with cirrhosis and HCC, and that HCV-related cirrhotic women before menopause might have the ability to protect against developing HCC via hepatic ER.

Abstract
BACKGROUND AND STUDY AIMS Bleeding due to esophageal variceal rupture is associated with an extremely high mortality rate. Variceal bleeding is frequent in patients who have a red color sign on endoscopy. However, the red color sign is subjectively evaluated on the basis of color tone and the shape of the varices. To allow standardization and facilitate consensus, an objective method of assessing the red color sign is needed. In this study, a system was established for quantifying the red color sign during endoscopic evaluation. PATIENTS AND METHODS Between July 1995 and February 1997, 55 untreated patients with portal hypertension and esophageal varices identified on upper gastrointestinal endoscopy were enrolled in the study. Images obtained about 5 cm oral to the esophagogastric junction during endoscopy were stored on magnetic optical disks using an endoscopic image processor. The still images were transmitted to a computer and analyzed using computer software. The RGB components (R, red; G, green; B, blue) were measured at points showing flare consistent with the red color sign. The endoscopic assessment was based on the Japanese Research Society for Portal Hypertension's general rules for recording endoscopic findings in esophagogastric varices. RESULTS The ratio of the red color area to the variceal area increased with increasing red color grade. There were significant positive correlations between the R and G, and G and B components. This suggests that comparing the R components alone would allow assessment of the color differences in the red color area and in the varices. The R value was significantly higher in the red color area (115 +/- 20) than in the varices (57 +/- 19). An R value of 90 was found at the boundary between the two parts (P < 0.001). CONCLUSIONS The red color area can be automatically calculated and quantified using the analysis program. Improvements in data storage methods may allow real-time evaluation during endoscopy in the future.

Abstract
OBJECTIVES The purpose of this study was to determine the relationship between the concentration of fluoride in drinking water and the prevalence of dental caries and fluorosis in seven Japanese communities with different concentrations of fluoride occurring naturally in the drinking water. METHODS A total of 1,060 10- to 12-year-old lifetime residents were examined to determine the prevalence of dental caries and fluorosis in communities with trace amounts to 1.4 ppm fluoride in the drinking water in 1987. Systemic fluorides (drops or tablets) have never been available in Japan and the market share of fluoride-containing toothpaste was 12 percent at the time of the study. RESULTS The prevalence of dental caries was inversely related and the prevalence of fluorosis was directly related to the concentration of fluoride in the drinking water. The mean DMFS in the communities with 0.8 to 1.4 ppm fluoride was 53.9 percent to 62.4 percent lower than that in communities with negligible amounts of fluoride. Multivariate analysis showed that water fluoride level was the strongest factor influencing DMFS scores. The prevalence of fluorosis ranged from 1.7 percent to 15.4 percent, and the increase in fluorosis with increasing fluoride exposure was limited entirely to the milder forms. CONCLUSIONS The findings of this study conducted in 1987 in Japan parallel those reported by Dean et al. in the early 1940s.

Abstract
We report an 18-year-old male patient who developed chronic hepatitis C after blood transfusion and had testicular dysfunction after irradiation for a testicular relapse of childhood acute lymphocytic leukemia after cessation of maintenance therapy, and the initiation of testosterone replacement therapy at puberty. Concomitant administration of estradiol resulted in a reduction in serum alanine aminotransferase and ferritin levels and hepatic iron concentration and staining after 2 years of estrogen therapy, although interferon therapy was withdrawn because of adverse effects. This observation suggests that endogenous estradiol may play a beneficial role in male patients with chronic hepatitis C.

Abstract
To determine the utility and limitations of an ultrasonic miniprobe (UMP) in the staging of gastric cancer, we evaluated 46 patients who underwent endoscopic ultrasonography (EUS) using an UMP and who were histologically determined to have gastric cancers. In every case, UMP findings were compared with histopathological findings after treatment. The total accuracy of UMP relative to the depth of tumor invasion was 71.7% (33/46 cases). Accuracy with respect to T1-m tumor diagnosis was 75.7% (22/29 cases), and for T1-sm, 76.9% (10/13 cases), but accuracy for T2 tumor diagnosis was low, due to ultrasound attenuation. When the analysis was carried out based on the size of tumor, the accuracy for UMP was 50.0% (9/18 cases) for all tumors over 20 mm and 85.7% (24/28 cases) for all tumors smaller than 20 mm. We conclude that UMP is suitable for investigation of tumor extension when the lesion is superficial and/or small gastric cancers which do not cause ultrasonic attenuation, but not when the tumor is large or located in certain sites, although conventional EUS is useful in some of these cases.

Abstract
Recently, subsegmental transcatheter hepatic arterial embolization under balloon occlusion of the corresponding hepatic vein has been performed to treat hepatic infarction in subregion hepatocellular carcinoma (HCC). Here, we report subsegmental transcatheter hepatic arterial embolization under balloon occlusion of the corresponding hepatic vein with styrene maleic acid neocarzinostatin lipiodol (SMANCS) (SMANCS-TAE under balloon occlusion of the corresponding hepatic vein). This study included 9 patients with HCC who underwent SMANCS-TAE under balloon occlusion of the corresponding hepatic vein. In all patients, the therapeutic effects (TE) were evaluated according to the criteria of direct response to liver cancer treatment on abdominal computed tomography (CT) 3 weeks after surgery. In 7 patients who could be followed for more than one year, there was no postoperative relapse at the site of treatment. Furthermore, this procedure facilitated the detection of accumulation of SMANCS not only in the tumor but also in the subregion of the tumor in patients with HCC involving immature arterial tumor neoplastic vessels. In patients with large HCC complicated by severe heart failure showing a poor general condition, this procedure allowed treatment to be completed without complication. SMANCS-TAE under balloon occlusion of the corresponding hepatic vein, which can also embolize the portal vein by applying targeting chemotherapy with SMANCS, may cause necrosis not only in the tumor but also in noncancerous liver tissues. This procedure may be an indication for a larger number of cases than standard TAE, facilitating more complete local treatment.

Abstract
OBJECTIVES This study assessed the treatment and posttreatment effects of a school-based, fluoride mouthrinse regimen. METHODS Children in a nonfluoridated community in Japan participated in a daily rinse program using a 0.05 percent NaF solution in nursery and primary schools, and a weekly rinse with 0.2 percent NaF in junior high school. Students were examined at least annually for dental caries and dental treatment was provided in a public dental clinic through the ninth grade. Incipient carious lesions with no cavitation were not restored. RESULTS The percent of children in grades one through nine (6-14 years of age) with caries-free permanent teeth increased from 13.4 percent in 1974 to 73.0 percent in 1991, while the mean DMFT decreased by 86 percent during this period. For 12-year-olds, mean DMFT scores declined to about one tooth per child after 1982. For adults 20 years of age, there was a 64 percent difference in DMFS between the treatment group who started the rinse regimen at 4 years of age and continued for 11 years, and the controls who lived in different districts and did not participate in a fluoride rinse regimen. CONCLUSIONS Children who began rinsing at 4 or 5 years of age benefited the most from the program. The program was inexpensive, simple to implement and well accepted by families and teachers. The conservative treatment policy in the public clinic likely contributed to the benefits derived by participants.
