Direct healthcare costs of patients with symptomatic diverticular disease randomized for either laparoscopic or open elective sigmoid resection are compared. Cost-effectiveness analysis of the laparoscopic approach compared with open sigmoid resections is presented. ⋯ Total healthcare costs of laparoscopic and open elective sigmoid resections for symptomatic diverticular disease are similar. As the clinical outcomes are in favor of the LSR group, candidates for an elective sigmoid resection should preferably be approached laparoscopically.

Robotic-assisted laparoscopic surgery (RALS) is evolving as an important surgical approach in the field of colorectal surgery. We aimed to evaluate the learning curve for RALS procedures involving resections of the rectum and rectosigmoid. ⋯ The three phases identified with CUSUM analysis of surgeon console time represented characteristic stages of the learning curve for robotic colorectal procedures. The data suggest that the learning phase was achieved after 15 to 25 cases.

Management of postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy.
The common and distressing complications of postoperative nausea and vomiting (PONV) are the main concern of 40-70% of patients undergoing laparoscopic cholecystectomy (LC). The first step in preventing PONV after LC is to reduce the risk factors involving patient characteristics, surgical procedure, anesthetic technique, and postoperative care. Particularly, the use of propofol-based anesthesia can reduce the incidence of PONV after LC. ⋯ Third, antiemetic therapy combined with a serotonin receptor antagonist (ondansetron, granisetron) and droperidol or dexamethasone is highly effective in the prevention of PONV after LC. Fourth, acupressure at the P6 point is a nonpharmacologic technique that is as effective as ondansetron for preventing PONV after LC. Knowledge regarding the risk factors for PONV and antiemetics is needed for the management of PONV after LC.

Rising health and financial costs associated with iatrogenic errors have drawn increasing attention to the dexterity of surgeons. With the advent of new technologies, such as robotic surgical systems and medical simulators, researchers now have the tools to analyze surgical motion with the goal of differentiating the level of technical skill in surgeons. ⋯ In this paper, we provide a clinical motivation for the importance of surgical skill evaluation. We review the current methods of tracking surgical motion and the available data-collection systems. We also survey current methods of surgical skill evaluation and show that most approaches fall into one of three methods: (1) structured human grading; (2) descriptive statistics; or (3) statistical language models of surgical motion. We discuss the need for an encompassing approach to model human skill through statistical models to allow for objective skill evaluation.
