BACKGROUND Recent data has shown that the use of warmed, humidified carbon dioxide (CO2) insufflation during laparoscopic surgery may be associated with better outcomes. METHODS We performed a randomized, doubleblind, prospective controlled clinical trial of 30 patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP). Patients were randomized(More)
PersPective Every year, 220,000 new cases of prostate cancer are detected. Approximately 18% of these cases will be treated with brachytherapy [1,2]. Over 1.2 million prostate needle biopsies are carried out every year in the USA. Systematic transrectal ultrasound (TRUS)-guided biopsy is the most frequently used technique for detecting prostate cancer and(More)
BACKGROUND Previous studies have reported that risk factors for elevated mortality after Roux-en-Y gastric bypass include male gender, as well as a very elevated BMI. The present study was aimed at determining whether these same risk factors applied to patients undergoing the duodenal switch (DS) operation. MATERIALS AND METHODS A retrospective chart(More)
Eighteen morbidly obese women had plasma brain-derived neurotrophic factor (BDNF) measured before bariatric surgery and 3 months postoperatively. We analyzed plasma BDNF levels in all the participants then subdivided according to menopausal status and type of surgery. Brain-derived neurotrophic factor decreased significantly in all the participants and in(More)
BACKGROUND The use of bariatric surgery to treat refractory obesity is increasingly common. The great weight loss that can result from these procedures has been shown to ameliorate certain deleterious effects of obesity. However, the effect of surgery on immune status is unclear. We investigated the relationship between surgical weight loss and peripheral(More)
BACKGROUND A standard approach for postoperative analgesia in laparoscopic surgery is to infiltrate the incisions with local anesthetic in combination with systemic opioids. The intraperitoneal introduction of local anesthetic in this setting has the potential to provide appropriate analgesia without the side effects of systemic opioids. We performed a(More)
Massive gastrointestinal hemorrhage secondary to metastatic renal cell carcinoma involving the jejunum is rare but has been previously described in the medical literature. Treatment options for metastatic renal cell carcinoma are limited, but transcatheter arterial embolization can be performed to control gastrointestinal hemorrhage either alone or prior to(More)
BACKGROUND Severe sepsis syndrome (SSS) and septic shock have an associated mortality ranging from 31 to 60%. Drotrecogin alfa (activated), activated protein C (APC), has been shown in a recent trial to decrease mortality from 44 to 31% in patients with SSS and a high risk of death. We present 3 patients who developed SSS after bariatric surgery and were(More)
BACKGROUND The most prevalent long-term complications in patients undergoing laparoscopic adjustable gastric band (LAGB) surgery are symmetric pouch dilation and gastric prolapse (slippage). However, no published data or a reliable model are available to evaluate the actual mechanism of band slippage or how to prevent it. The objective of the present study(More)
