Multicenter Study
Recurrence rate after absorbable tack fixation of mesh in laparoscopic incisional hernia repair.
The mesh fixation technique in laparoscopic incisional hernia repair may influence the rates of hernia recurrence and chronic pain. This study investigated the long-term risk of recurrence and chronic pain in patients undergoing laparoscopic incisional hernia repair with either absorbable or non-absorbable tacks for mesh fixation. ⋯ Absorbable tack fixation of the mesh was associated with a higher risk of recurrence than non-absorbable tacks for laparoscopic mesh repair of incisional hernia, but did not influence chronic pain.

Multicenter Study
International validation of a risk score for complications and reinterventions after endovascular aneurysm repair.
Lifelong surveillance is considered mandatory after endovascular repair (EVAR) of abdominal aortic aneurysms to detect endograft complications and prevent aneurysm rupture. Current protocols are not cost-effective or clinically effective. The international validity of the St George's Vascular Institute (SGVI) score for EVAR complications was examined. ⋯ This study has provided international validation of a morphological risk score that predicts mid-term reinterventions and endograft complications. The results may enable risk-stratified surveillance after EVAR.

Multicenter Study
Hospital teaching status and volume related to mortality after pancreatic cancer surgery in a national cohort.
The association between hospital teaching status and mortality after pancreatic resection is not well explored. Although hospital volume is related to short-term mortality, the effect on long-term survival needs investigation, taking into account hospital teaching status and selective referral patterns. ⋯ Hospital teaching status was strongly related to decreased mortality in both the short and long term. This may relate to processes of care rather than volume per se. Very low-volume hospitals had the highest short-term mortality risk.

Randomized clinical trial of skin closure by subcuticular suture or skin stapling after elective colorectal cancer surgery.
The best suture method to prevent incisional surgical-site infection (SSI) after clean-contaminated surgery has not been clarified. ⋯ UMIN000004001 (http://www.umin.ac.jp/ctr).
