There is growing evidence that mini-gastric bypass (MGB) is a safe and effective procedure. Operative outcome and long-term follow-up of a consecutive cohort of patients who underwent MGB are reported. The data on 1,000 patients who underwent MGB from November 2005 to January 2011 at an academic institution were reviewed. Mean age was 33.15 ± 10.17 years(More)
Thyroid hormones define basal metabolism throughout the body, particularly in the intestine and viscera. Gastrointestinal manifestations of dysthyroidism are numerous and involve all portions of the tract. Thyroid hormone action on motility has been widely studied, but more complex pathophysiologic mechanisms have been indicated by some studies although(More)
Acute mesenteric ischemia (AMI) is a highly-lethal surgical emergency. Several pathophysiologic events (arterial obstruction, venous thrombosis and diffuse vasospasm) lead to a sudden decrease in mesenteric blood flow. Ischemia/reperfusion syndrome of the intestine is responsible for systemic abnormalities, leading to multi-organ failure and death. Early(More)
BACKGROUND AND OBJECTIVES Packed red blood cell transfusion has been associated with increased infection in a variety of critically ill patient populations. We evaluated the microbiology and time course of infection in transfused patients in the intensive care unit (ICU) as no data exist on these parameters. MATERIALS AND METHODS We performed a(More)
BACKGROUND Human natural orifice transluminal endoscopic surgery (NOTES) is slowed down by technical hurdles. Concomitantly, single-incision laparoscopy has been increasingly reported as an alternative. By reducing the invasiveness of standard laparoscopy, we may further reduce postoperative pain, decrease morbidity, preserve abdominal wall, and enhance(More)
The parathyroid glands are the main regulator of plasma calcium and have a direct influence on the digestive tract. Parathyroid disturbances often result in unknown long-standing symptoms. The main manifestation of hypoparathyroidism is steatorrhea due to a deficit in exocrine pancreas secretion. The association with celiac sprue may contribute to(More)
Single-incision laparoscopic surgery (SILS) and natural orifice transluminal endoscopic surgery (NOTES) have rapidly gained pace worldwide, potentially replacing conventional laparoscopic surgery (CLS) as the preferred colorectal surgery technique. Currently available data mainly consist of retrospective series analyzed in four meta-analyses. Despite(More)
Therapeutic attitudes for papillary thyroid microcarcinoma (PTMC) range from observation alone to aggressive management. Clinicopathologic features, therapeutic options, and follow-up results are described in a series of PTMC revealed by cervical adenopathies. Twelve patients were enrolled in this retrospective study. They were all treated by(More)
OBJECTIVES/HYPOTHESIS This study evaluates the accuracy of ultrasonography in guided unilateral parathyroidectomy to treat primary hyperparathyroidism. STUDY DESIGN Retrospective study. METHODS Two hundred fifty-three patients with primary hyperparathyroidism underwent preoperative ultrasonography. Two groups were defined. Group 1 included the patients(More)
This study aims to review the safety of thyroidectomy combined with cervical neck dissection without drainage in well-differentiated thyroid carcinoma (WDTC). The medical records of consecutive patients who underwent thyroidectomy without drainage for WDTC were retrospectively reviewed. Group 1 included 123 patients who underwent thyroidectomy with central(More)
