Purpose: The TWIST (Testicular Work-up for Ischemia and Suspected Torsion) score was developed to allow for expedited diagnosis of testicular torsion (TT) in children based on clinical variables: edema (2 points), hard mass (2), absent cremasteric reflex (1), high-riding testis (1) and nausea/vomiting (1). We sought to validate the TWIST Score applied by non-expert physicians for the diagnosis of testicular torsion in an adult population.
Methods: We prospectively analyzed all consecutive males presenting to a tertiary hospital with acute scrotum.
Purpose: To evaluate the effects of pneumoperitoneum with carbon dioxide and helium on renal function and morphology in a rat model.
Methods: Twenty four rats were randomized into three groups (n=8): gasless insufflation ('open', Pressure=0 mmHg), carbon dioxide pneumoperitoneum at 12 mmHg, and helium pneumoperitoneum at 12 mmHg; all lasting 90 minutes..
Article Synopsis
- The study aimed to assess the safety and feasibility of a new laparoscopic technique for segmental colectomy and anastomosis in rats.
- Thirty rats were divided into three groups: one underwent laparoscopic surgery at low pressure, another at high pressure, and the control group had open surgery, with post-op evaluations on day seven.
- Results showed no major complications in any group, with one case of leakage in the low-pressure group, and overall, the technique was deemed safe and effective.
