Randomized Controlled Trial
Randomized clinical trial of mechanochemical and endovenous thermal ablation of great saphenous varicose veins.
A variety of minimally invasive techniques are available for the treatment of varicose great saphenous vein (GSVs). Non-tumescent, non-thermal ablation methods have been developed. This study compared mechanochemical ablation (MOCA), a non-tumescent, non-thermal ablation technique, with two endovenous thermal ablation methods requiring tumescence in an RCT. ⋯ The GSV occlusion rate 1 year after treatment was significantly higher after EVLA and RFA than after MOCA. Quality of life was similar between interventions. Registration number: NCT03722134 (http://www.clinicaltrials.gov).

Postoperative readmission after colorectal resection is common. It is unknown whether patients who receive readmission care from the surgeon who performed the index surgery have improved mortality. This study evaluated whether postdischarge continuity of care, defined at the hospital and surgeon level, was associated with decreased mortality after colorectal surgery. ⋯ Readmission after colorectal resection not under the care of the index operating surgeon is associated with an increased risk of 30-day mortality. Addressing processes of care that are affected by surgeon care continuity may decrease surgical deaths.

Observational Study
Nationwide observational study of mortality from complicated intra-abdominal infections and the role of bacterial cultures.
The benefit of taking intra-abdominal cultures during source control procedures in patients with complicated intra-abdominal infection (CIAI) is unknown. The aim of this study was to evaluate whether intra-abdominal cultures reduce the mortality rate of CIAI. ⋯ Intra-abdominal cultures obtained during source control procedures may reduce in-hospital mortality, especially in patients with lower intestinal perforation, biliary tract infection/perforation, or healthcare-associated or high-risk community-acquired CIAI.

Visceral obesity is one of the risk factors for clinically relevant pancreatic fistula after pancreatic resection. The objective of this study was to evaluate the impact of intraperitoneal lipolysis on postoperative pancreatic fistula. ⋯ Intraperitoneal lipolysis significantly exacerbates pancreatic fistula after pancreatic resection. Inhibition of lipolysis by intraperitoneal administration of a lipase inhibitor could be a promising therapy to reduce clinically relevant postoperative pancreatic fistula. Surgical relevance Clinically, there are two types of pancreatic fistula after pancreatic resections: harmless biochemical leak and harmful clinically relevant pancreatic fistula. Visceral obesity is one of the known risk factors for clinically relevant pancreatic fistula; however, the underlying mechanisms remained to be elucidated. Patients with clinically relevant pancreatic fistula had a higher free fatty acid concentration in the drain discharge, suggesting a relationship between intraperitoneal lipolysis and pancreatic fistula. The experimental model of pancreatic fistula demonstrated that intraperitoneal lipolysis caused deterioration in pancreatic fistula, suggesting that intraperitoneal lipolysis is one of the mechanisms that drives biochemical leakage to clinically relevant pancreatic fistula. Intraperitoneal administration of a lipase inhibitor prevented lipolysis as well as pancreatic fistula deterioration in the experimental model, suggesting a future clinical application for lipase inhibitors in prevention of clinically relevant pancreatic fistula.
