Multicenter Study Comparative StudyLong-term and perioperative outcomes of laparoscopic versus open liver resection for colorectal liver metastases with propensity score matching: a multi-institutional Japanese study.
The aim of the present study was to clarify the surgical outcome and long-term prognosis of laparoscopic liver resection (LLR) compared with conventional open liver resection (OLR) in patients with colorectal liver metastases (CRLM). ⋯ In selected CRLM patients, LLR is strongly associated with lower blood loss and shorter hospital stay and has equivalent long-term survival comparable with OLR.

Multicenter Study Comparative StudyMulticenter comparative study of laparoscopic and open distal pancreatectomy using propensity score-matching.
Laparoscopic distal pancreatectomy has been shown to be associated with favorable postoperative outcomes using meta-analysis. However, there have been no randomized controlled studies yet. This study aimed to compare laparoscopic and open distal pancreatectomy using propensity score-matching. ⋯ Laparoscopic distal pancreatectomy was associated with more favorable perioperative outcomes than open distal pancreatectomy.

Multicenter StudyEvaluation of portal vein invasion of distal cholangiocarcinoma as borderline resectability.
The concept of borderline resectability has not yet been introduced for extrahepatic cholangiocarcinoma (ECC). In this study, the surgical results of ECC patients were analyzed to clarify the implications of surgery for distal ECC with portal vein (PV) invasion as a preliminary step for the introduction of the concept of borderline resectability. ⋯ PV invasion of distal ECC should be regarded as indicating borderline resectability.

Multicenter StudyA novel difficulty scoring system for laparoscopic liver resection.
Early on, laparoscopic liver resection (LLR) was limited to partial resection, but major LLR is no longer rare. A difficulty scoring system is required to guide surgeons in advancing from simple to highly technical laparoscopic resections. Subjects were 90 patients who had undergone pure LLR at three medical institutions (30 patients/institution) from January 2011 to April 2014. ⋯ A 10-level difficulty index by linear modeling based on clinical information revealed a weighted kappa statistic of 0.72 and that scored by the extent of liver resection, tumor location, tumor size, liver function, and tumor proximity to major vessels revealed a weighted kappa statistic of 0.68. We proposed a new scoring system to predict difficulty of various LLRs preoperatively. The calculated score well reflected difficulty.

Multicenter StudyProposal for a sub-classification of hepato-biliary-pancreatic operations for surgical site infection surveillance following assessment of results of prospective multicenter data.
Surgical site infection (SSI) surveillance in Japan is based on the National Nosocomial Infection Surveillance system, which categorizes all hepato-biliary-pancreatic surgeries, except for cholecystectomy, into "BILI." We evaluated differences among BILI procedures to determine the optimal subdivision for SSI surveillance. ⋯ Hepatectomy and non-hepatectomy BILI differ with regard to the incidence of and risk factors for developing SSI. These surgeries should be assessed separately when conducting SSI surveillance.
