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)
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)
INTRODUCTION Endoscopic surgical repair of inguinal hernia is currently conducted using 2 techniques: the totally extraperitoneal (TEP) and the transabdominal (TAPP) hernia repair. The TEP procedure is technically advantageous, because of the use of no mesh fixation and the elimination of the peritoneal flap, leading to less postoperative pain and faster(More)
BACKGROUND 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. METHODS All the patients who underwent laparoscopic inguinal herniorrhaphy at the authors' hospital during a period of 11(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)
Simulators are useful tools in the development of laparoscopic skills. However, little is known about the effectiveness of short laparoscopic training sessions and how retention of skills occurs in surgical trainees who are naïve to laparoscopy. This study analyses the retention of laparoscopic surgical skills in medical students without prior surgical(More)
INTRODUCTION 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. METHODS Twelve adult female pigs underwent peritoneoscopy with liver and peritoneal(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)
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)
