Comparative Study
The effect of distractions in the operating room during endourological procedures.
Professionals working in the operating room (OR) are subject to various distractions that can be detrimental to their task performance and the quality of their work. This study aimed to quantify the frequency, nature, and effect on performance of (potentially) distracting events occurring during endourological procedures and additionally explored urologists' and residents' perspectives on experienced ill effects due to distracting factors. ⋯ Distracting events occur frequently in the OR. Equipment problems and communication, the latter both procedure-related and medically irrelevant, have the largest impact on the sterile team and regularly interrupt procedures. Distracting stimuli can influence performance negatively and should therefore be minimized. Further research is required to determine the direct effect of distraction on patient safety.

Comparative Study
Robot-assisted gastrojejunal anastomosis does not improve the results of the laparoscopic Roux-en-Y gastric bypass.
Traditional laparoscopic surgery presents some difficulties for morbidly obese patients due to limited motion of instruments related to a thick abdominal wall, intraabdominal fat, and a large hepatic left lobe, with consequent loss of dexterity and greater musculoskeletal discomfort. Robotic technique could potentially overcome these limitations. This study aimed to evaluate robot-assisted laparoscopic Roux-en-Y gastric bypass in morbidly obese patients and to compare the results of robotic assistance with those of traditional laparoscopic technique. ⋯ Although safe and intuitive, the robotic approach was burdened by a longer operative time and higher equipment costs. Moreover, it did not seem to provide a real advantage over standard laparoscopy in terms of hospital length of stay and complications rates.

Video. Single-incision laparoscopic left lateral segmentectomy of colorectal liver metastasis.
Laparoscopic surgery via a single port is an evolving technique being applied to an increasing variety of operations [1]. Multiple series over the past 3 years have shown single-incision laparoscopic cholecystectomy to be feasible and safe [2]. The ergonomic difficulties of single-port laparoscopy include a loss of instrument triangulation and operation with camera and instruments in parallel. ⋯ The patient was able to resume an oral diet and full mobility free of opioid analgesia on the first postoperative day. The resection margin was clear. This video demonstrates that the authors' technique is feasible and oncologically safe for selected patients requiring liver resection.

Comparative Study
Evaluation of intraperitoneal placement of absorbable and nonabsorbable barrier coated mesh secured with fibrin sealant in a New Zealand white rabbit model.
This study aimed to evaluate the acute and chronic fixation strength of fibrin sealant (FS) as an alternative method of fixation for laparoscopic ventral hernia repair (LVHR). ⋯ In a chronic rabbit model of LVHR, fixation strength with FS alone was inadequate for selected nonabsorbable and absorbable barrier-coated meshes. The acute and chronic fixation strengths of suture+FS were equivalent or superior to the fixation strength of tacks alone. Using a combination of suture and FS for mesh fixation in LVHR may provide adequate fixation while decreasing postoperative pain due to spiral titanium tacks. In this preclinical series, mesh secured to the peritoneal surface by FS alone may have led to early recurrence.
