Multicenter Study Comparative Study
A partnership model between high- and low-volume hospitals to improve results in hepatobiliary pancreatic surgery.
To optimize the results of low-volume (LV) centers for hepatopancreaticobiliary (HPB) surgery. ⋯ Our partnership model helped improve postoperative outcomes at the LV center. Results at the LV hospital were comparable with the HV centers, although 2 years of partnership were required to achieve this in pancreatic surgery.

Randomized Controlled Trial Multicenter Study
Multicenter double-blinded randomized controlled trial of standard abdominal wound edge protection with surgical dressings versus coverage with a sterile circular polyethylene drape for prevention of surgical site infections: a CHIR-Net trial (BaFO; NCT01181206).
To determine whether circular plastic wound edge protectors (CWEPs) significantly reduce the rate of surgical site infections (SSIs) in comparison to standard surgical towels in patients undergoing laparotomy. ⋯ Our trial shows that CWEPs are effective at reducing the incidence of SSIs in elective and clean or clean-contaminated open abdominal surgery.

Randomized Controlled Trial Multicenter Study
Effectiveness of regional hyperthermia with chemotherapy for high-risk retroperitoneal and abdominal soft-tissue sarcoma after complete surgical resection: a subgroup analysis of a randomized phase-III multicenter study.
To determine whether regional hyperthermia (RHT) in addition to chemotherapy improves local tumor control after macroscopically complete resection of abdominal or retroperitoneal high-risk sarcomas. ⋯ In patients with macroscopically complete tumor resection, RHT in addition to chemotherapy resulted in significantly improved local tumor control and DFS without increasing surgical complications. Within a multimodal therapeutic concept for abdominal and retroperitoneal high-risk sarcomas, RHT is a treatment option beside radical surgery and should be further evaluated in future trials.

Randomized Controlled Trial Multicenter Study
Prolonged time to surgery after neoadjuvant chemoradiotherapy increases histopathological response without affecting survival in patients with esophageal or junctional cancer.
To determine the relation between time to surgery (TTS) after neoadjuvant chemoradiotherapy (nCRT) and pathologically complete response (pCR), surgical outcome, and survival in patients with esophageal cancer. ⋯ Prolonged TTS after nCRT increases the probability of pCR and is associated with a slightly increased probability of postoperative complications, without affecting disease-free and overall survivals. We conclude that TTS can be safely prolonged from the usual 4 to 6 weeks up to at least 12 weeks, which facilitates a more conservative wait-and-see strategy after neoadjuvant chemoradiotherapy to be tested.

Multicenter Study Clinical Trial Observational Study
Relevance of postoperative peak transaminase after elective hepatectomy.
Determine whether inflow occlusion is correlated with peak-postoperative serum-transaminases (PSTs) and whether PST is predictive of outcome after liver resections. ⋯ PST is not correlated with ischemia time and should not be used as a surrogate of postoperative outcome.
