Randomized Controlled Trial
Biomolecular inflammatory response to surgical energy usage in laparoscopic surgery: results of a randomized study.
Use of surgical energy is integral to laparoscopic surgery (LS). Energized dissection (ED) has a potential to impact the biomolecular expression of inflammation due to ED-induced collateral inflammation. We did this triple-blind randomized controlled (RCT) study to assess this biomolecular footprint in an index LS, i.e., laparoscopic cholecystectomy (LC). ⋯ Clinical Trials Registry, India (REF/2014/06/007153).

Urgent laparoscopic cholecystectomy has been established as the best treatment for acute cholecystitis. However, conservative treatment is advocated for high-risk patients. Failure of conservative treatment can result in high-risk operations with relatively high rates of operative morbidity. Percutaneous cholecystostomy is a good option for these patients. Recently, percutaneous aspiration of the gall bladder without drain has been described. ⋯ Conservative treatment and delayed operation is an acceptable option for acute cholecystitis. Percutaneous gall bladder aspiration is a simple and effective procedure, with a high success rate and low morbidity. Laparoscopic cholecystectomy after drainage of the gall bladder has low morbidity with a relatively low conversion rate.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) is one of the most common bariatric procedures worldwide, but the importance of gastric pouch size is still under debate. We have studied how pouch size affects risk of marginal ulcer and excess body mass index loss (EBMIL%) at 6 weeks and 1 year postoperatively. ⋯ A smaller pouch reduces the risk of marginal ulcers, but does not predict better weight loss at 1 year. Additional stapling should be avoided as each extra centimeter increases the relative risk of marginal ulcers by 14 %.

It has been postulated that increased operator workload during task performance may increase fatigue and surgical errors. The National Aeronautics and Space Administration-Task Load Index (NASA-TLX) is a validated tool for self-assessment for workload. Our study aims to assess the relationship of workload and performance of novices in simulated laparoscopic tasks of different complexity levels before and after training. ⋯ NASA-TLX score is an accurate reflection of the complexity of simulated laparoscopic tasks in the FLS curriculum. This also correlates with the relationship of test scores between the three tasks. Simulation training improves both performance score and workload score across the tasks.

Laparoscopic major hepatectomy (LMH) for hepatocellular carcinoma (HCC) is currently perceived a complex and challenging laparoscopic procedure and is limited to a few expert teams. This study analyzed the short- and long-term outcomes of LMH for HCC compared with open hepatectomy. ⋯ This study shows the feasibility of LMH for HCC compared to open hepatectomy in regard to both short- and long-term outcomes. LMH offers many advantages commonly attributed to laparoscopy and is well suited for HCC with cirrhosis when performed by experienced surgeons.
