Multicenter Study
Minimally invasive esophagectomy: results of a prospective phase II multicenter trial-the eastern cooperative oncology group (E2202) study.
The primary aim of this trial was to assess the feasibility of minimally invasive esophagectomy (MIE) in a multi-institutional setting. ⋯ This prospective multicenter study demonstrated that MIE is feasible and safe with low perioperative morbidity and mortality and good oncological results. This approach can be adopted by other centers with appropriate expertise in open esophagectomy and minimally invasive surgery.

Multicenter Study
Tumor location is a strong predictor of tumor progression and survival in T2 gallbladder cancer: an international multicenter study.
To determine the prognostic impact of tumor location in gallbladder cancer. ⋯ After curative resection of T2 gallbladder cancer, tumor location predicts the pattern of recurrence and survival.

Multicenter Study
The role of biological sex in severely traumatized patients on outcomes: a matched-pair analysis.
Analyze sex differences in TraumaRegister DGU (TR-DGU). ⋯ Males are more susceptible to multiple organ failure, sepsis, and mortality after trauma. Differences were not exclusively related to reproductive age and thus cannot be attributed to sex hormones alone. Females aged 16 to 44 years seem to tolerate shock better. Higher susceptibility to sepsis might be explained by male immune function or increased systemic burden from higher rates of surgical interventions.

The study aim was to quantify the burden of complications of pancreatoduodenectomy (PD). ⋯ This study develops a quantitative non-risk-adjusted benchmark for postoperative morbidity of PD. The method quantifies the burden of types and grades of postoperative complications and should prove useful in identifying areas that require quality improvement.

Randomized Controlled Trial Multicenter Study
Laparoscopic repair of very large hiatus hernia with sutures versus absorbable mesh versus nonabsorbable mesh: a randomized controlled trial.
Determine whether absorbable or nonabsorbable mesh in repair of large hiatus hernias reduces the risk of recurrence, compared with suture repair. ⋯ No significant differences were seen for recurrent hiatus hernia, and the clinical differences were unlikely to be clinically significant. Overall outcomes after sutured repair were similar to mesh repair.
