: Postoperative pain or recovery at 3 weeks after repair of midline incisional hernias does not differ between LR and OR, but the LR results in better physical function and less surgical site infections than the OR does. (ClinicalTrials.gov Identifier: NCT00472537).
The laparoscopic and the open preperitoneal mesh methods of repair for recurrent groin hernias were associated with the lowest risk of reoperation. Although the method of repair in previous surgery must be considered, these techniques are the preferred methods for recurrent groin hernia surgery.
Endoscopic repair for first recurrent groin hernia surgery, after an index anterior repair, was associated with less chronic pain, discomfort and disability compared to anterior approach. Chronic pain increased after a second recurrent repair. A high surgeon's volume reduced the risk of chronic pain after open posterior mesh repair.
Background Laparoscopic skills training and evaluation outside the operating room is important for all surgeons learning new skills. To study feasibility, a video box trainer tracking 4-dimensional (4D) metrics was evaluated as a laparoscopic training tool. Method Simball Box is a video box trainer with authentic surgical instruments and camera with video recording, equipped with 4D motion analysis registered through trocars using machine vision technology. Residents attending a 3-day laparoscopy course were evaluated performing a laparoscopic surgical knot at start, middle, and end. Metrics were obtained. Feedback data were presented in reference to expert/tutorial performance. Results Ten right-handed residents were included. Median time (range) to finish the task was 359 (253-418), 129 (95-166), and 95 (52-156) seconds; 655%, 236%, and 174% of tutorial performance, with significance pre-/midcourse (P < .0001), pre-/postcourse (P < .0001), and mid-/postcourse (P = .0050). Combined median total instrument motion decreased pre-/midcourse from 1208 (845-1751) to 522 cm (411-810 cm); P = .042 to 405 cm (246-864 cm) postcourse; pre-/postcourse P < .0001; 673%, 291%, 225% of tutorial performance. Total angular distance in radians (range) was 150 (87-251), 65 (42-116), and 50 (33-136) with significance pre-/midcourse (P = .022) and pre-/postcourse (P = .0002). Right-handed average speed (cm/s) increased: 1.94 (1.11-2.27) pre-, 2.39 (1.56-2.83) mid-, 2.60 (1.67-3.19) postcourse with significance pre-/midcourse (P = .022) and pre-/postcourse (P = .002). Average acceleration (mm/s(2)) and motion smoothness (µm/s(3)) failed to show any difference. Conclusion For laparoscopic training and as a promising evaluation device, Simball Box obtained metrics mirroring progression well.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
