Purpose: While it is widely accepted that laparoscopic total extraperitoneal (TEP) inguinal herniorrhaphy has decreased post-operative pain, there are conflicting data as to whether instillation of local anesthetic into the preperitoneal space improves post-operative pain in these patients. We designed a prospective study to evaluate this. Secondary outcomes include time spent in the PACU, need for narcotic pain medication, and total amount of narcotics required postoperatively.

Background: There is significant variability in weight loss after bariatric surgery. We hypothesize that part of this variability may be predetermined by genetic differences associated with metabolic homeostasis. MicroRNA (miRNA) are short pieces of RNA that regulate gene expression and are readily detectable in serum.

Bariatric surgery remains the most effective intervention for long-term sustained weight loss and resolution of comorbidities. It should be considered for patients with a body mass index of 40 kg/m or greater regardless of comorbidities and for patients with a body mass index of 30 kg/m with significant comorbidities, such as diabetes and sleep apnea. For these patients, laparoscopic bariatric surgery, including sleeve gastrectomy, Roux-en-Y gastric bypass, and duodenal switch, is safe with minimal perioperative risks of morbidity and mortality.

Article Synopsis
  • A low-cost training model for parotid surgery was created using a 3D-printed skeleton, silicone soft tissue, and a facial nerve simulation that uses copper wire to signal instrument contact.
  • The model was validated through surveys assessing its face and content validity after residents performed a simulated superficial parotidectomy following a video demo.
  • Results showed faculty scored higher than residents on the simulation, and both groups agreed the model could greatly benefit junior residents in their training.
