Randomized Controlled Trial Multicenter Study Comparative Study
Endovascular repair versus open repair of ruptured abdominal aortic aneurysms: a multicenter randomized controlled trial.
Randomized comparison of endovascular repair (EVAR) with open repair (OR) in patients with a ruptured abdominal aortic aneurysm (RAAA). ⋯ This trial did not show a significant difference in combined death and severe complications between EVAR and OR. Mortality for OR both in randomized patients and in cohort patients was lower than anticipated, which may be explained by optimization of logistics, preoperative CT imaging, and centralization of care in centers of expertise.

Multicenter Study Controlled Clinical Trial
A total laparoscopic approach reduces the infertility rate after ileal pouch-anal anastomosis: a 2-center study.
To assess the infertility rate after laparoscopic ileal pouch-anal anastomosis (IPAA). ⋯ The infertility rate appears to be lower after laparoscopic IPAA than after open surgery.

Multicenter Study
Pathohistological subtype predicts survival in patients with intraductal papillary mucinous neoplasm (IPMN) of the pancreas.
To investigate different subtypes of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas and their prognostic value. ⋯ Evaluation of IPMN subtypes supports postoperative patient prognosis prediction. Therefore, subtype differentiation could lead to improvements in clinical management. Potentially identifying subgroups with the need for adjuvant therapy may be possible.

Comparative Study
Feasibility of split liver transplantation for 2 adults in the model of end-stage liver disease era.
To examine the results of split liver transplantation for 2 adults in the model of end-stage liver disease (MELD) era. ⋯ Although most of the recipients with split liver transplantation had high MELD scores, the results were comparable with those of living donor liver transplantation. Split liver transplantation for 2 adults is still feasible in the MELD era.
