Abstract
Jejunostomy, which requires the fixation of the jejunum to the abdominal wall, is commonly used as an enteral feeding access after esophagectomy. However, this procedure sometimes causes severe complications, such as mechanical bowel obstruction. In 2009, we developed a modified approach to insert an enteral feeding tube through the reconstructed gastric tube using the round ligament of the liver. The aim of this study is to investigate the usefulness of this approach as compared to the approach through jejunostomy. Between January 2005 and March 2015, 420 patients with thoracic esophageal cancer underwent esophagectomy via thoracotomy and laparotomy. Of these, 214 underwent feeding jejunostomy (FJ group) and 206 patients underwent feeding via gastric tube with round ligament of the liver (FG group). Catheter-related complications, other postoperative complications, and mortality were compared between the two groups. The incidence of catheter site infection during catheterization in the FG group was significantly lower (n = 1/206, 0.5%) compared to the FJ group (n = 11/214, 5.1%) (P < 0.01). The postoperative bowel obstruction did not occur in the FG group, while it occurred in eight patients (3.7%) in the FJ group (P < 0.01). The incidences of other catheter-related and postoperative complications were similar between the two groups. Feeding catheter gastrostomy with the round ligament of the liver can be a useful enteral feeding access after esophagectomy, because the incidence rate of severe catheter-related complications, such as surgical site infection and mechanical obstruction tend to be lower with this technique compare to jejunostomy.

Abstract
BACKGROUND Bismuth type IV perihilar cholangiocarcinoma has traditionally been categorized as unresectable disease. The aim of this study was to review experience with a resection-based strategy in patients who have type IV perihilar cholangiocarcinoma. METHODS Medical records of consecutive patients with a diagnosis of type IV perihilar cholangiocarcinoma between 2006 and 2015 were reviewed retrospectively. Primary outcomes assessed were surgical results and long-term survival. RESULTS Of the 332 patients with type IV tumour, 216 (65·1 per cent) underwent resection. Left hepatic trisectionectomy was the most common procedure (112 patients). Combined vascular resection was performed in 131 patients. Median duration of operation was 607 (range 356-1045) min, and blood loss was 1357 (209-10 349) ml. Complications of Clavien-Dindo grade III or more developed in 90 patients (41·7 per cent) and four (1·9 per cent) died from complications within 90 days. Survival rates were better for the 216 patients whose tumours were resected than for the 116 patients with unresected tumours (32·8 versus 1·5 per cent at 5 years; P < 0·001). Patients with pN0 M0 disease after resection had a favourable 5-year survival rate of 53 per cent. Percutaneous transhepatic biliary drainage, blood transfusion, lymph node metastasis and distant metastasis were identified as independent negative prognostic factors for survival. CONCLUSION Although resection for type IV tumour is technically demanding with high morbidity, it can be performed with low mortality and offers better survival probability in selected patients.

Abstract
OBJECTIVES To examine associations of dietary variety with changes in lean mass and physical performance during a 4-year period in an elderly Japanese population. DESIGN Four-year prospective study. SETTING The Hatoyama Cohort Study and Kusatsu Longitudinal Study, Japan. PARTICIPANTS 935 community-dwelling Japanese aged 65 years or older. MEASUREMENTS Dietary variety was assessed using a 10-item food frequency questionnaire. Body composition was determined by multifrequency bioelectrical impedance analysis, and physical performance (grip strength and usual gait speed) was measured in surveys at baseline and 4 years later. Longitudinal analysis included only participants who were originally in the upper three quartiles of lean body mass, appendicular lean mass, grip strength, and usual gait speed. The outcome measures were decline in lean body mass, appendicular lean mass, grip strength, and usual gait speed, defined as a decrease to the lowest baseline quartile level at the 4-year follow-up survey. Associations of dietary variety with the outcome measures were examined by logistic regression analysis adjusted for potential confounders. RESULTS In the fully adjusted model, the odds ratios for decline in grip strength and usual gait speed were 0.43 (95% confidence interval, 0.19-0.99) and 0.43 (confidence interval, 0.19-0.99), respectively, for participants in the highest category of dietary variety score as compared with those in the lowest category. Dietary variety was not significantly associated with changes in lean body mass or appendicular lean mass. CONCLUSION Among older adults, greater dietary variety may help maintain physical performance, such as grip strength and usual gait speed, but not lean mass.

Abstract
OBJECTIVES To examine the associations of dietary variety with body composition and physical function in community-dwelling elderly Japanese. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS A total of 1184 community-dwelling elderly adults aged 65 and over. MEASUREMENTS Dietary variety was assessed with a food frequency questionnaire (maximum, 10 points) that encompassed the 10 main food components of Japanese meals (meat, fish/shellfish, eggs, milk, soybean products, green/yellow vegetables, potatoes, fruit, seaweed, and fats/oils). Body composition was determined by multifrequency bioelectrical impedance analysis. Physical function was assessed by measuring grip strength and usual walking speed. Multiple linear regression analysis was used to examine the associations of dietary variety with body composition and physical function. RESULTS After adjusting for potential confounders, higher dietary variety scores were independently associated with higher lean mass (β (SE): 0.176 (0.049), p<0.001) and appendicular lean mass (β (SE): 0.114 (0.027), p<0.001) but not with body fat mass. Elders with a higher dietary variety score had greater grip strength and faster usual walking speed (β (SE): 0.204 (0.071), p=0.004, and β (SE): 0.008 (0.003), p=0.012, respectively). CONCLUSION Greater dietary variety was significantly associated with greater lean mass and better physical function in Japanese elders. The causal relationship warrants investigation in a prospective study.

Abstract
INTRODUCTION In the case reported here, the authors observed ovarian small cell carcinoma of the pulmonary type as it developed. CASE The patient was a 48-year-old woman who underwent a hysterectomy for CIN3 in 2007. A year later, the woman underwent screening for ovarian cancer. A gradually growing ovarian mass was noted. This mass was found to be a mixed tumor. This mixed tumor grew to 36 mm in size, and six months later it had enlarged to 119 mm. After surgery, the tumor was pathologically diagnosed as an ovarian small cell carcinoma of the pulmonary type with a neuroendocrine nature that was positive for CD56 and synaptophysin. Postoperatively, the patient received six courses of combined therapy with irinotecan and cisplatin (CPT-P therapy), and the patient has survived disease- free for over two years. CONCLUSION Findings suggested that ovarian small cell carcinoma of the pulmonary type is a type I ovarian malignancy that develops through an adenoma-carcinoma sequence.

Abstract
BACKGROUND Surgical treatment for perihilar cholangiocarcinoma frequently involves hepatectomy and extrahepatic bile duct resection with a choledochojejunostomy (CJ). Cholangitis owing to bilioenteric anastomosis is a common complication. The impact of CJ or regurgitating cholangitis on the liver regeneration process after major hepatectomy is unknown. METHODS Rats underwent 70 per cent hepatectomy (Hx group) or hepatectomy with CJ (Hx + CJ group). The intrahepatic inflammatory response, hepatic regeneration rate, and expression of regeneration-associated genes in the liver and blood were compared between these two groups. RESULTS Levels of hepatobiliary markers in the blood were significantly higher 4 and 7 days after operation in the Hx + CJ group than the Hx group. Intrahepatic expression of inflammation-associated genes, such as interleukin 6 and tumour necrosis factor α, was also significantly higher in the Hx + CJ group on days 4 and 7. A progressive periportal inflammatory response was identified in the Hx + CJ group by histological examination. The hepatic regeneration rate was significantly lower in the Hx + CJ group than in the Hx group on day 2 (mean(s.d.) 14·2(6·3) versus 21·4(2·6) per cent; P = 0·013) and day 4 (32·4(5·3) versus 41·3(4·4) per cent; P = 0·004). Gene expression levels of hepatic regeneration-promoting factors such as hepatocyte growth factor were significantly lower in the Hx + CJ group than the Hx group on day 1. CONCLUSION CJ perturbs early liver regeneration after hepatectomy. An excessive inflammatory response in the liver and suppression of liver regeneration-associated factors may play a role. Surgical relevance Patients with perihilar cholangiocarcinoma may need major hepatectomy with extrahepatic bile duct resection and choledochojejunostomy. This carries a substantial risk of postoperative complications including liver failure. A rat model of partial hepatectomy with choledochojejunostomy was established. The molecular mechanisms underlying liver regeneration, and perturbation of this process by duodenobiliary reflux via the choledochojejunostomy, are described. The results give insight into the pathophysiological events following major hepatectomy with extrahepatic bile duct resection and choledochojejunostomy. This may help to develop a treatment strategy to reduce postoperative liver failure.
