Long-term quality of life (QoL) after liver resection is becoming increasingly important, as improvements in operative methods and perioperative care have decreased morbidity and mortality rates. In this study, postoperative QoL after resection of benign or malignant liver tumours was evaluated. ⋯ This study confirmed overall good QoL in patients undergoing liver resection for benign or malignant tumours, which improved after surgery. Benign diseases were associated with better short- and long-term QoL scores.

Review Meta Analysis
Meta-analysis of microsatellite instability in relation to clinicopathological characteristics and overall survival in gastric cancer.
Several associations between microsatellite instability (MSI) and other clinicopathological factors have been reported in gastric cancer, but the results have been ambiguous. This systematic review and meta-analysis investigated the relationship between MSI and overall survival and clinicopathological characteristics of patients with gastric cancer. ⋯ MSI in gastric cancer was associated with good overall survival, reflected in several favourable clinicopathological tumour characteristics.

Randomized Controlled Trial Multicenter Study Comparative Study
Randomized clinical trial of adjuvant gemcitabine chemotherapy versus observation in resected bile duct cancer.
Although some retrospective studies have suggested the value of adjuvant therapy, no recommended standard exists in bile duct cancer. The aim of this study was to test the hypothesis that adjuvant gemcitabine chemotherapy would improve survival probability in resected bile duct cancer. ⋯ The survival probability in patients with resected bile duct cancer was not significantly different between the gemcitabine adjuvant chemotherapy group and the observation group. Registration number: UMIN 000000820 (http://www.umin.ac.jp/).

Multiple surgical procedures in a single patient are relatively common and lead to dependent (clustered) data. This dependency needs to be accounted for in study design and data analysis. A systematic review was performed to assess how clustered data were handled in inguinal hernia trials. The impact of ignoring clustered data was estimated using simulations. ⋯ Clustering was rarely considered in inguinal hernia trials. The simulations underline the importance of considering clustering as part of the statistical analysis to avoid false-positive and false-negative results, and hence inappropriate study conclusions.

Screening for abdominal aortic aneurysm (AAA) is known to reduce AAA-related mortality; however, the psychological impact of population AAA screening is unclear. The aim was to assess the impact of AAA diagnosis on quality of life (QoL) using data from an established AAA screening programme. ⋯ This study suggests that screening for AAA does reduce mental QoL; however, this effect is transient (less than 12 months). Men diagnosed with AAA have a consistently worse physical QoL compared with controls.
