This study was undertaken to evaluate the outcomes after laparoscopic Heller myotomy with anterior fundoplication and diverticulectomy for patients with achalasia and esophageal diverticula. 634 patients undergoing laparoscopic Heller myotomy and anterior fundoplication from 1992 to 2015 are prospectively followed up; patients were stratified for those(More)
Many studies purport that obesity, and specifically visceral fat, impact survival after pancreaticoduodenectomy for pancreatic adenocarcinoma. However, these studies involve crude measures of obesity [eg, body mass index (BMI)] or visceral fat [eg, linear measurements on computed tomographic (CT) scans]. Some studies purport that weight loss and muscle(More)
Since the Leapfrog Group established hospital volume criteria for pancreaticoduodenectomy (PD), the importance of surgeon volume versus hospital volume in obtaining superior outcomes has been debated. This study was undertaken to determine whether low-volume surgeons attain the same outcomes after PD as high-volume surgeons at high-volume hospitals. PDs(More)
Heller myotomy provides durable and effective treatment of achalasia. Due to recurrence or persistence of symptoms, a small subset of patients seeks reoperation. This study was undertaken to determine if reoperative Heller myotomy provides salutary amelioration of symptoms. 609 patients undergoing laparoscopic Heller myotomy between 1992 to 2013 were(More)
Ten mature rams were paired on the basis of pre-treatment semen production and assigned randomly to one of two treatments. Treatments were bilateral intraepididymal injections of 3 ml of 50% (w/v) CaCI2 in .9% NaC1 (w/v) or 3 ml .9% NaCI. Semen was collected twice weekly for 5 weeks prior to treatment and for 7 weeks following treatment. Mounting times,(More)
Although anti-reflux surgery has been used liberally over the past decades for the treatment of gastroesophageal reflux disease (GERD), few studies report follow-up after 10 years. This study was undertaken to report follow-up on 100 consecutive GERD patients up to 22 years after utilizing a laparoscopic fundoplication. Hundred consecutive patients(More)
