Anatomy and Complications Following Laparoscopic Sleeve Gastrectomy: Radiological Evaluation and Imaging Pitfalls
(2011)To evaluate the post-operative gastric anatomy depicted by upper gastrointestinal gastrografin swallow studies (UGI) and report radiological work-up and management of complications following laparoscopic sleeve gastrectomy ... -
Early and long-term results of surgery for severe necrotising pancreatitis
(2004)Background: Necrotising pancreatitis is a challenging problem for the surgeon, as it is associated with considerable morbidity and mortality. The indications, timing of surgical intervention and type of procedure continue ... -
The Fat Content of Small Primary Breast Cancer Interferes with Radiofrequency-Induced Thermal Ablation
(2009)Background: Radiofrequency (RF) thermal ablation is a minimally invasive technique of local mass elimination with variable efficiency. Methods: Ten patients with small primary breast cancer diagnosed preoperatively by core ... -
Habib EndoHPB: A Novel Endobiliary Radiofrequency Ablation Device. An Experimental Study
(2013)Background: The Habib EndoHPB is a bipolar radiofrequency (RF) catheter developed to be introduced across malignant strictures of the bile ducts, so that RF energy can locally ablate the tumor prior to stent placement. ... -
Impact of intraoperative hypotension on hospital stay in major abdominal surgery
(2011)Although the relationship between preoperative risk factors and outcomes has been extensively studied, the effect of intraoperative hemodynamic changes in a patient's postoperative course has been less well defined. We ... -
Laparoendoscopic Rendezvous Versus Preoperative ERCP and Laparoscopic Cholecystectomy for the Management of Cholecysto-Choledocholithiasis Interim Analysis of a Controlled Randomized Trial
(2012)Background: Although the ideal management of cholecysto-choledocholithiasis is controversial, the 2-stage approach [endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and common bile duct (CBD) clearance ... -
Laparoendoscopic rendezvous: an effective alternative to a failed preoperative ERCP in patients with cholecystocholedocholithiasis
(2010)Background Although the ideal management of cholelithiasis and concomitant choledocholithiasis is controversial, the two-stage approach [endoscopic retrograde cholangiopancreatography (ERCP), sphincterotomy, and common ... -
Laparoscopic appendectomy: Differences between male and female patients with suspected acute appendicitis
(2007)Background: The role of laparoscopy in the management of patients with suspected acute appendicitis remains controversial. It has been suggested that laparoscopy is useful mainly in young women of reproductive age because ... -
Laparoscopic cholecystectomy under spinal anesthesia: A pilot study
(2006)Background: Regional anesthesia has not been used as the sole anesthetic procedure other than in the scenario of a patient at high risk to undergo laparoscopic cholecystectomy with CO2 pneumoperitoneum under general ... -
Laparoscopic ventral hernia repair under spinal anesthesia: a feasibility study
(2008)BACKGROUND: Regional anesthesia has not been used as the sole anesthetic procedure in laparoscopic ventral hernia repair due to the fear of potential adverse effects of the pneumoperitoneum. However, there are recent reports ... -
Modified radiofrequency-assisted liver resection: A new device
(2007)Background: Radiofrequency ablation (RF) is emerging as new therapeutic method for the management of hepatic tumors. So far the RF-assisted hepatectomy has been described using an electrode initially designed for ablation ... -
New trends in the management of colonic trauma
(2005)Background: The management of colon trauma seems to have swung from the "diversion dogma" to a more liberal use of primary repair. However, there are still debatable issues, regarding the management of destructive injuries ... -
A Novel Experimental Animal Model of Arterial Stenosis Based on Endovascular Radiofrequency Energy Application
(2011)Purpose: To develop a new rabbit model of arterial stenosis using endovascular radiofrequency (RF) energy. Materials and Methods: Ten rabbits were used for multiple endovascular RF applications to the aorta and left common ... -
The role of antibiotic prophylaxis in elective tension-free mesh inguinal hernia repair: results of a single-centre prospective randomised trial
(2007)Hernia repair is one of the so-called clean operations. Many surgeons, however, use antibiotics, especially in the mesh repair era, without strong evidence to support this policy. We conducted a single-centre prospective ... -
Spinal vs general anesthesia for laparoscopic cholecystectomy
(2008)Objective: To compare spinal anesthesia with the gold standard general anesthesia for elective laparoscopic cholecystectomy in healthy patients. Design: Controlled randomized trial. Setting: University hospital. Patients: ... -
Timing of laparoscopic cholecystectomy for acute cholecystitis: A prospective non randomized study
(2006)AIM: To study the timing of laparoscopic cholecystectomy for patients with acute cholecystitis. METHODS: Between January 2002 and December 2005, all American Society of Anesthesiologists classification (ASA) I, II and III ... -
Transduodenal sphincteroplasty and transampullary septectomy for sphincter of Oddi dysfunction
(2002)Background: The diagnosis and management of sphincter of Oddi dysfunction are controversial issues. Both surgical and endoscopic series report modest success in the treatment of this condition. There is evidence from ... -
Vascular injuries in laparoscopic cholecystectomy: An underestimated problem
(2006)Background: Bile duct injury is a severe complication of laparoscopic cholecystectomy and many reports focus on this topic, especially regarding the long- term success of repair of these injuries. There is some concern, ...
