Meta Analysis Comparative Study
Comparison of treatment effect estimates from prospective nonrandomized studies with propensity score analysis and randomized controlled trials of surgical procedures.
We aimed to compare treatment effect estimates from NRSs with PS analysis and RCTs of surgery. ⋯ There was no statistically significant difference in treatment effect between NRSs with PS analysis and RCTs. Prospective NRSs with suitable and careful PS analysis can be relied upon as evidence when RCTs are not possible.

Randomized Controlled Trial Multicenter Study Comparative Study
Outpatient versus hospitalization management for uncomplicated diverticulitis: a prospective, multicenter randomized clinical trial (DIVER Trial).
We compare the results of 2 different strategies for the management of patients with uncomplicated left colonic diverticulitis and to analyze differences in quality of life and economic costs. ⋯ Outpatient treatment is safe and effective in selected patients with uncomplicated acute diverticulitis. Outpatient treatment allows important costs saving to the health systems without negative influence on the quality of life of patients with uncomplicated diverticulitis. Trial registration ID: EudraCT number 2008-008452-17.

Meta Analysis Comparative Study
Long-term oncologic outcomes of laparoscopic versus open surgery for rectal cancer: a pooled analysis of 3 randomized controlled trials.
To compare long-term oncologic outcomes between laparoscopic and open surgery for rectal cancer and to identify independent predictors of survival. ⋯ This pooled analysis with a follow-up of more than 10 years confirms the long-term oncologic safety of laparoscopic surgery for rectal cancer.

Randomized Controlled Trial Multicenter Study Comparative Study
Antecolic versus retrocolic route of the gastroenteric anastomosis after pancreatoduodenectomy: a randomized controlled trial.
To investigate the relationship between the route of gastroenteric (GE) reconstruction after pancreatoduodenectomy (PD) and the postoperative incidence of delayed gastric emptying (DGE). ⋯ The route of GE reconstruction after PD does not influence the postoperative incidence of DGE or other complications. The etiology and treatment of DGE, which occurs frequently after both procedures, need further investigation. The GE reconstruction after PD should be routed according to the surgeon's preference.

To systematically determine the imaging findings for distinguishing malignant and benign branch-duct type intraductal papillary mucinous neoplasms (BD-IPMNs), including mixed type, and their diagnostic value through meta-analysis of published studies. ⋯ Presence of mural nodules should be regarded highly suspicious for malignancy warranting a surgical excision whereas cyst size greater than 3 cm, MPD dilatation (5-9 mm), or thick septum/wall may better be managed by careful observation and/or further evaluation.
