Failures of antireflux procedures occur in 5% to 10% of the patients. Our objective is to report our experience with laparoscopic management of failed antireflux operations. Of 1698 patients who underwent laparoscopic treatment of gastroesophageal reflux disease (GERD), 53 were reoperations following either a previous open or laparoscopic antireflux(More)
Bacterial contamination from viscerotomy is a barrier to natural orifice translumenal endoscopic surgery (NOTES). The aim of this survival study is to evaluate pure (totally) transvaginal NOTES bacterial contamination compared with laparoscopy in pigs. Twelve adult female pigs underwent peritoneoscopy with liver and peritoneal biopsies, using either(More)
OBJECTIVE To evaluate the impact of NOTES compared to laparoscopic surgery, through the analysis of physiological parameters as well as surgical complications and postoperative outcome, for liver biopsy. METHODS 12 female pigs were divided into two groups: laparoscopy group (GLap) and NOTES group (GNote). The animals underwent liver biopsy by peritoneal(More)
Although laparoscopic inguinal herniorrhaphy is considered safe, several complications may occur. This study aimed to evaluate the complications observed in 780 laparoscopic inguinal herniorrhaphies at the authors’ hospital. All the patients who underwent laparoscopic inguinal herniorrhaphy at the authors’ hospital during a period of 11 years were enrolled(More)
OBJECTIVE To assess the acquisition of basic laparoscopic skills of Medical students trained on a surgical simulator. METHODS First- and second-year Medical students participated on a laparoscopic training program on simulators. None of the students had previous classes of surgical technique, exposure to surgical practice nor training prior to the(More)
BACKGROUND Liver resection constitutes the main treatment of most liver primary neoplasms and selected cases of metastatic tumors. However, this procedure is associated with significant morbidity and mortality rates. AIM To analyze our experience with liver resections over a period of 10 years to determine the morbidity, mortality and risk factors of(More)
INTRODUCTION The Lichtenstein technique is commonly used in inguinal hernia repair and a polypropylene mesh is the most frequently used mesh. Mesh migration into the colon has been rarely reported in the literature. Here we report a case of a colocutaneous fistula that developed following delayed mesh migration into the sigmoid colon. PRESENTATION OF CASE(More)
CONTEXT Diagnosis and treatment of cystic neoplasms of the pancreas increased significantly in the last decades. There are only a few Brazilian publications on these tumors. The majority of them are limited to reports of one or few cases. OBJECTIVE To present our experience with 27 patients with cystic neoplasms of the pancreas. METHODS Demographic(More)
Despite inguinal hernia repair being one of the most common elective operations performed in general surgical practice, there are many controversies including indications for repair and selection of the surgical technique. In recent years, laparoscopic repair has gained wider acceptance because it is associated with fewer postoperative complications and(More)
Esophageal leiomyomas are the most common benign tumors of the esophagus. Surgical enucleation is warranted for symptomatic patients. Thoracoscopic enucleation is the preferable approach for being less invasive by avoiding the discomfort and complications associated to larger thoracic incisions. The purpose of this study was to review our experience with(More)
