Microwave Ablation with 915 Mhz Vs 2.45 Ghz. What Is the Difference?
We present preliminary results from an upcoming prospective, non-randomized comparison of patients with liver tumors treated with either a 915 MHz or a 2.45 GHz microwave ablation system. Results from this institution using a commercially available 915 MHz microwave ablation system (ValleyLab, Boulder, CO) for malignant tumors in the liver have been previously published, using… Continue Reading
Single Port Access (spa) Cholecystectomy: a Comparison to Standard Mutliport Cholecystectomy
Over the last two years the field of minimally invasive surgery has seen the emergence of single port laparoscopic techniques. In May 2007, we performed our first Single Port Access (SPA) cholecystectomy. This technique provides an alternative approach to accessing the abdominal cavity for minimal access procedures. Additionally, it enhances cosmesis and decreases skin incisions.… Continue Reading
Laparoscopic Intervention for Massive, Rapidly Progressive Pancreatic Pseudocyst Disease with Endocrine and Exocrine Dysfunction
Introduction: Therapeutic interventions for pancreatic pseudocyst disease are most often based on symptoms, lesion size, and in particular duration of the lesion. Conventional wisdom typically avoids early surgical therapy for “immature” pseudocysts, citing concerns of cyst wall thickness, durability, and ability to hold suture material for a secure anastomosis. We present a case of a… Continue Reading

Laparoscopic Near Infrared Fluorescence Imaging of Biliary Tree Anatomy
Objective of the study: The primary goal of this study was the successful intraoperative near infrared fluorescence (NIRF) imaging of extra and intra hepatic bile ducts using the SPY and laparoscopic SPY2 scope systems (Novadaq Technologies Inc.) after parenteral administration of Indocyanine Green (ICG). Optimal NIRF imaging of biliary anatomy occurs when sufficient amount of… Continue Reading

Laparoscopic Enucleation of Pancreas Tail or Head Lesion: Report of 13 Cases
Introduction) Laparoscopic enucleation of pancreas (LEP) can be best treatment option avoiding resection or pancreatic anastomosis, if performed appropriately and safely. But reports regarding LEP have been rare and mainly case report. So, we herein report the largest series of LEP to date.Method) From April 2006 to Aug 2008, total 13 cases of LEP were… Continue Reading
Single Port Access (spatm) Cholecystectomy: Preservation of the Critical View
The Single Port Access (SPATM) technique utilizes the umbilicus as a single portal of entry into the abdominal cavity. The goal of this access technique is to maintain the current, safe dissection of standard multiport laparoscopic cholecystectomy while performing the entire operation through one incision concealed within the umbilicus.The critical view is a proven paradigm… Continue Reading
Robot-Assisted Biliary Reconstruction – Short-term Outcomes with Minimally-invasive Roux-en-Y Hepaticojejunostomy
Objective: A minimally invasive approach to hepatobiliary reconstruction can be technically difficult due to the need to suture a fine structure in an enclosed space, intimately related to critical vascular structures, often with significant adhesions or fibrosis. Using the da Vinci surgical system can aid in visualization and maneuverability, facilitating the dissection and anastomosis in… Continue Reading
Clipless Minilaparoscopic Cholecystectomy: A Comparative Cost Study for a Minimally Invasive and Cost Effective Procedure.
INTRODUCTION: For the surgical treatment of gallbladders diseases, the laparoscopic cholecystectomy has been accepted as the gold standard all over the world. Although, it seems to be clear that the needlescopic procedure, called minilaparoscopic cholecystectomy (MLC) is superior in many aspects when it is compared not only to open surgery, but also compared to the… Continue Reading

Establishing Nd:yag Laser Based Left Lateral Liver Resection: Comparison of Open, Laparoscopic and Hand Assisted Approach in a Porcine Model
Objectives:Aim of this study was to assess the feasibility and safety of a 1064 nm Nd:YAG laser for left lateral liver resection in a porcine model. Laparoscopy and hand assisted laparoscopic surgery were evaluated and compared to conventional open surgery. Methods:A group of 15 pigs were randomized for three different approaches of left lateral liver… Continue Reading
Fluorescent Cholangiography During Laparoscopic Cholecystectomy By Intravenous Injection of Indocyanine Green
Objective of the technique: To delineate bile duct anatomy during laparoscopic cholecystectomy (LC) using fluorescent cholangiography with preoperative intravenous injection of indocyanine green (ICG).Methods: Our fluorescent cholangiography technique is based on the principle that ICG is excreted into bile and that protein-bound ICG emits light with a peak wavelength of around 830 nm when illuminated… Continue Reading
Laparoscopic Pancreatoduodenectomy:safety and Efficacy of Radical Resection
Aim: To prove that radical laparoscopic pancreatoduodenectomy for malignancy can be safely performed, adhering to sound oncological principles. Methods: From March 1998 to January 2008, we retrospectively reviewed 52 patients undergoing laparoscopic pancreatoduodenectomy with nodal clearance for malignancy, and present a step-by-step video demonstration. Results: Mean age was 62 years and the types were ampullary,… Continue Reading

Laparoscopic Management of Patients with Early Forms of Gallbladder Cancer
INTRODUCTION: Laparoscopy can represent an useful tool in the management of patients undergoing reoperation for gallbladder cancer detected after the study of the cholecystectomy specimen. The aim of this study is to evaluate the feasibility and outcome of a series of patients undergoing initial laparoscopic management . METHODS AND PROCEDURES : According a prospective protocol,… Continue Reading
Assessing the Potential and Limitations of Laparoscopic Ultrasound in the Staging of Pancreatic Cancers
Introduction: Although the role of laparoscopic ultrasound (LUS) during staging laparoscopy for pancreatic cancers is well established there is no consensus as to whether it provides useful information over and above other imaging modalities. Aim: To evaluate the value of intra-operative LUS in the pre-operative assessment of pancreatic cancer. Methods: A retrospective consecutive case series… Continue Reading
