Observational Study
The impact of intra-operative interruptions on surgeons' perceived workload: an observational study in elective general and orthopedic surgery.
Surgeons' intra-operative workload is critical for effective and safe surgical performance. Detrimental conditions in the operating room (OR) environment may add to perceived workload and jeopardize surgical performance and outcomes. This study aims to evaluate the impact of different intra-operative workflow interruptions on surgeons' capacity to manage their workload safely and efficiently. ⋯ Our study documents the unique contribution of different interruptions on surgeons' workload; whereas case-irrelevant communications may be beneficial for mental fatigue and stress in routine cases, procedural interruptions and case-irrelevant communication may contribute to surgeons' mental focus deteriorating. Well-designed OR environments, surgical leadership, and awareness can help to control unnecessary interruptions for effective and safe surgical care.

We have evaluated the safety and feasibility of combining median-to-lateral and anterior-to-median (MLAM) approaches to perform laparoscopic complete mesocolic excision (CME) with radical lymph node dissection along the gastrocolic trunk of Henle (GTH) for right hemicolon cancer. ⋯ Laparoscopic CME conducted by fusion fascia exposure with radical lymph node dissection along the GTH via a combination of MLAM approaches is a safe and feasible procedure for right hemicolon cancer.

Comparative Study Clinical Trial
Ergonomic analysis of robot-assisted and traditional laparoscopic procedures.
Many laparoscopic surgeons report musculoskeletal symptoms that are thought to be related to the ergonomic stress of performing laparoscopy. Robotic surgical systems may address many of these limitations. To date, however, there have been no studies exploring the quantitative ergonomics of robotic surgery. In this study, we sought to compare the activation of bilateral biceps, triceps, deltoid, and trapezius muscle groups during traditional laparoscopic surgery (TLS) and robot-assisted laparoscopic surgery (RALS) procedures, as quantified by surface electromyography (sEMG). ⋯ We have quantitatively examined the ergonomics of TLS and RALS and shown that in a single surgeon, TLS procedures are associated with significantly elevated biceps, triceps, and deltoid activation bilaterally when compared to RALS procedures.

Clinical Trial
Symptomatic and physiologic outcomes one year after peroral esophageal myotomy (POEM) for treatment of achalasia.
Peroral esophageal myotomy (POEM) is a new endoscopic operation for the treatment of achalasia. Here, we report 1-year physiologic and symptomatic outcomes following the procedure. ⋯ In this series, POEM resulted in greater than 90% symptomatic treatment success at mean 15-month follow-up. Rates of iatrogenic gastroesophageal reflux, as measured both by symptoms and 24-h pH monitoring, appeared to be on par with recent studies of patients undergoing laparoscopic Heller myotomy and pneumatic dilation.

Over 700,000 laparoscopic cholecystectomies are performed yearly in the US. Despite multiple advantages of laparoscopic surgery, the increased rate of bile duct injury (BDI) compared to the traditional, open approach to cholecystectomy remains problematic. Due to the seriousness of bile duct injury, the time has come for an aggressive educational campaign to better train laparoscopic surgeons in order to reduce the incidence of this life-threatening and expensive complication. ⋯ BDI is an appropriate target for the application of educational theories of expertise. Designing better educational interventions for the prevention of BDI will require uncovering the hidden knowledge of expert surgeons and incorporating the processes of reinvestment and progressive problem solving that are inherent to expert performance.
