Laparoscopic Nissen fundoplication assessment: task analysis as a model for the development of a procedural checklist.
Learning an advanced laparoscopic procedure is a complex process that requires clinical exposure, direct teaching, and deliberate practice. Expert surgeons automate their knowledge, making it difficult to teach incremental steps. Our aim was to deconstruct the steps of a laparoscopic Nissen fundoplication (LNF) and develop a procedural checklist assessment instrument. ⋯ The task analysis and Delphi technique was successful in reaching expert consensus on the procedural steps of a LNF and in creating a valid checklist. By capturing automated knowledge in a checklist form, we can scaffold resident learning and improve feedback for an advanced laparoscopic case.

Comparative Study
Ergonomics, user comfort, and performance in standard and robot-assisted laparoscopic surgery.
Robot-assisted surgical systems have been introduced to improve the outcome of minimally invasive surgery. These systems also have the potential to improve ergonomics for the surgeon during endoscopic surgery. This study aimed to compare the user's mental and physical comfort in performing standard laparoscopic and robot-assisted techniques. Surgical performance also was analyzed. ⋯ In this experimental setup, the use of a robot-assisted surgical system was of value in both cognitive and physical stress reduction. Robotic assistance also demonstrated improvement in performance.

Comparative Study
Assessment of pain by face scales after gastrectomy: comparison of laparoscopically assisted gastrectomy and open gastrectomy.
Laparoscopic gastrectomy is reported to cause little pain. However, only the total number of analgesics used has been studied to date. Because pain is a subjective experience, its evaluation requires indicators for the subjective assessment. ⋯ The pain score for laparoscopic gastrectomy was low. There was no significant difference in pain between procedures while epidural anesthesia was in effect. Pain subsided earlier with laparoscopic than with open gastrectomy. The same characteristics were observed with both LADG and LATG.

Median arcuate ligament syndrome (MALS) is a rare entity that manifests as abdominal pain, nausea, vomiting, and diarrhea. The median arcuate ligament is a fibrous band that connects the crura of the diaphragm. ⋯ After viewing a video that described the laparoscopic median arcuate ligament release technique at the 2006 SAGES meeting and reviewing the online video, we report our experience with two cases and discuss the lessons learned in performing the procedure within a training program. We also discuss the extent to which surgical resident participation contributes to intraoperative complications during a new and complex surgery.
