Comparative Study
Thoracoscopic esophageal mobilization during minimally invasive esophagectomy: a head-to-head comparison of prone versus decubitus positions.
Minimally invasive esophagectomy (MIE) is being performed at an increasing number of institutions. The thoracoscopic portion is generally performed in the left lateral decubitus position. Recently there has been increasing interest in esophageal mobilization in the prone position and the potential benefits of this technique with regard to operative time, surgeon ergonomics, and operative exposure. We sought to objectively compare thoracoscopic mobilization of the esophagus in the left lateral decubitus position versus the prone position and identify potential differences between the two techniques. ⋯ Prone thoracoscopic esophageal mobilization appears to be equivalent to decubitus thoracoscopic esophageal mobilization with respect to blood loss, number of lymph nodes dissected, and complications, but with a significant reduction in thoracoscopic surgical time.

Randomized Controlled Trial
Randomized controlled trial investigating the effect of music on the virtual reality laparoscopic learning performance of novice surgeons.
Findings have shown that music affects cognitive performance, but little is known about its influence on surgical performance. The hypothesis of this randomized controlled trial was that arousing (activating) music has a beneficial effect on the surgical performance of novice surgeons in the setting of a laparoscopic virtual reality task. ⋯ Music in the operating theater may have a distracting effect on novice surgeons performing new tasks. Surgical trainers should consider categorically switching off music during teaching procedures.

Comparative Study
Comparison of two low-molecular-weight heparin dosing regimens for patients undergoing laparoscopic bariatric surgery.
Venous thromboembolic events (VTE) are a morbidity and mortality concern for patients undergoing laparoscopic bariatric surgery. Although VTE prophylaxis is recommended in bariatric surgery, data with regard to monitoring and appropriate dosing of low-molecular-weight heparin are limited. Enoxaparin prophylactic doses ranging from 30 to 60 mg every 12 h have been used for this population. The authors hypothesized that higher prophylactic enoxaparin doses (60 mg) would yield more appropriate heparin antifactor Xa (anti-Xa) concentrations than the 40-mg dosage for bariatric surgery patients. ⋯ Enoxaparin 60-mg every 12 h was superior to a dosage of 40 mg every 12 h in achieving therapeutic anti-Xa concentrations and avoiding subtherapeutic anti-Xa levels. However, the 60-mg group had a number of supratherapeutic levels. Future studies evaluating the relationship of anti-Xa concentrations and outcomes with larger numbers of morbidly obese patients are needed.

The use of mesh for laparoscopic repair of large hiatal hernias may reduce recurrence rates in comparison with primary suture repair. However, there is a potential risk of mesh-related oesophageal complications due to prosthesis erosion. The aim of this study was to evaluate a lightweight polypropylene mesh (TiMesh) repair of hiatal hernias with particular reference to intraluminal erosion. ⋯ Laparoscopic reinforcement of primary hiatal closure with TiMesh leads to a durable repair in patients with large hiatal hernias. Endoscopic follow-up did not show any signs of mesh-related complications after prosthetic reinforcement of the crural repair. Our preliminary results suggest that it is safe to proceed with this lightweight polypropylene mesh for reinforcement of the hiatal repair.

Morbid obesity is associated with a high prevalence of cholecystopathy, and there is an increased risk of cholelithiasis during rapid weight loss following gastric bypass. In the era of open gastric bypass prophylactic cholecystectomy was advocated. However, routine cholecystectomy at laparoscopic gastric bypass is controversial. ⋯ In our experience, concomitant cholecystectomy at LRYGB for ultrasonography-confirmed gallbladder pathology is feasible and safe. It reduces the potential for future gallbladder-related morbidity, and the need for further surgery.
