Previous studies have shown that self-expanding metal stents are an effective method for palliation of malignant biliary or duodenal obstruction. We present our experience with the use of simultaneous self-expandable metal stents for palliation of malignant biliary and duodenal obstruction. ⋯ Combined self-expandable metal stenting for simultaneous palliation of malignant biliary and duodenal obstruction may provide a safe and less invasive alternative to surgical palliation with an acceptable clinical outcome. Simultaneous self-expandable metal stents should be considered as a treatment option for patients who are poor candidates for surgery.

Instead of open laparotomy, laparoscopy can be used safely and effectively for the diagnosis and treatment of traumatic abdominal injuries. ⋯ The short-term results from this study suggest that laparoscopy is a safe, feasible, effective procedure for the evaluation and treatment of hemodynamically stable patients with abdominal trauma, and that it can reduce the number of nontherapeutic laparotomies performed.

Chronic postoperative pain has been reported in as many as 62.9% of patients after inguinal herniorrhaphy. Moderate to severe neuropathic pain requiring intervention develops in 2.2% to 11.9% of patients as a result of ileoinguinal and genitofemoral nerve entrapment. Cryoanalgesic ablation has been successful in treating chronic pain from craniofacial neuralgia, facet joint syndrome, and malignant pain syndromes. We report our experience using cryoanalgesic ablation for chronic ileoinguinal and genitofemoral neuralgia after inguinal herniorrhaphy. ⋯ Cryoanalgesic ablation successfully eliminates ileoinguinal and genitofemoral neuralgia in most patients, and should be considered early in the treatment of patients with postherniorrhaphy neuropathic pain.

Randomized Controlled Trial Comparative Study Clinical Trial
Duplex ultrasound assessment of femoral venous flow during laparoscopic and open gastric bypass.
Pneumoperitoneum (PP) and the reverse Trendelenburg (RT) position have been shown to decrease femoral blood flow, resulting in venous stasis. However the effects of PP and RT on femoral venous flow have not been evaluated in morbidly obese patients undergoing laparoscopic gastric bypass (GBP). We analyzed the effects of PP and RT on peak systolic velocity and the cross-sectional area of the femoral vein during laparoscopic and open GBP. We further examined the efficacy of intermittent sequential compression devices in reversing the reduction of femoral peak systolic velocity. ⋯ Pneumoperitoneum and reverse Trendelenburg position during laparoscopic and open GBP are independent factors for the development of venous stasis. Combining the reverse Trendelenburg position with pneumoperitoneum during laparoscopic GBP further reduces femoral peak systolic velocity and hence increases venous stasis. The use of sequential compression devices was partially effective in reversing the reduction of femoral peak systolic velocity, but it did not return femoral peak systolic velocity to baseline levels.
