Laparoscopic Revision After Roux-en-Y Gastric Bypass for Pouch Enlargement
Some patients that have had a gastric bypass display a distension of the gastric pouch that may participate to weight regain. We studied the impact of pouch size reduction on weight changes.Seven patients aged 42.9±8.9 yrs, with an initial BMI of 42.5±5.7, who had had a Roux-en-Y gastric bypass (RYGB) were reoperated on from June… Continue Reading

Laparoscopic Revision of Antireflux Surgery to Roux-en-Y Gastric Bypass in Morbidly Obese Patients
Introduction: Laparoscopic Roux-en-Y gastric bypass (LRYGB) is an effective treatment for gastroesophageal reflux disease (GERD) in morbidly obese patients. However, LRYGB in patients with a previous anti-reflux procedure may present a significant technical challenge. We aimed to demonstrate the safety and efficacy of laparoscopic revision from anti-reflux procedures to LRYGB in a series of morbidly… Continue Reading

Laparoscopic Right Portal Vein Ligation for Metastatic Liver Tumors
In the case of an extended hepatectomy, percutaneous transhepatic portal vein embolization (PTPE) is necessary for a metastatic liver tumor, in order to enlarge the remnant liver. In a case with a giant tumor occuping the right lobe, PTPE would unavoidably injury the remnant liver. There is a method to perform portal vein branch ligation… Continue Reading
Laparoscopic Robot Assisted Distal Pancreatectomy in an Hiv + Patient for Mucinous Cystic Neoplasm with Ovarian Struma: a Case Report
Background: Mucinous cystic neoplasms of the pancreas are distinct entities with malignant potential, the vast majority occurring in middle aged women. The presence of ovarian struma and lack of communication with the main pancreatic duct is required for the diagnosis of mucinous cystic neoplasm. Case history: We report on a twenty six year old female,… Continue Reading
Laparoscopic Robot-Assisted Pancreatic Cystgastrostomy: Surgical Technique and Short-term Outcomes
Background: Pancreatic pseudocysts are a relatively common complication of acute pancreatitis. While there a number of approaches to the management of pseudocysts, internal surgical drainage is generally the most effective in preventing recurrence. The use of minimally invasive techniques for pseudocyst drainage is rising. The use of the da Vinci surgical system allows for a… Continue Reading
Laparoscopic Roux-en-Y Cystjejunostomy and Choledochojejunostomy for a Pancreatic Pseudocyst with Biliary Obstruction
The minimally-invasive management of uncomplicated chronic pancreatic pseudocysts has been shown to be safe and effective with laparoscopy becoming the preferred surgical modality in many patients. Complicated pancreatic pseudocysts, however, continue to pose a challenge to the surgeon, and the ideal surgical treatment remains unclear. We are reporting the first case to our knowledge of… Continue Reading

Laparoscopic Roux-en-Y Gastric Bypass: Short Term Weight Loss Outcomes At a Military Treatment Facility
Introduction: Short term weight loss outcomes after Roux-en-Y gastric bypass (LGB) are not found in large numbers within the literature. This study establishes a weight loss curve that individual patients may be compared to at follow up visits. Methods: This study is a retrospective analysis of all patients receiving LGB from the initial inception of… Continue Reading

Laparoscopic Roux-en-Y Hepatico- or Choledocho-jejunostomy in the Era of Laparoscopic Surgery
Background: With rapid development and wide application of laparoscopic procedure in biliary surgery, laparoscopic Roux-en-Y hepatico- or choledo-chojejunostomy is being performed more frequently than ever since our first report on 2004. Method: Between February 1997 and September 2008, 36 patients underwent laparoscopic biliary-enteric anastomosis with the diagnosis of choledochal cyst, recurrent CBD stone, intrahepatic duct… Continue Reading
Laparoscopic Sigmoid Colon Resection in the Management of a 13-year-old Patient with Severe Rectal Prolapse
Background: Rectal prolapse in the pediatric population is usually a benign and self-limited condition. We present a rare case of severe recurrent rectal prolapse on a 13-year- old patient associated with a redundant sigmoid colon treated with laparoscopic resection. Case Presentation: A 13-year-old male presented with a five-year history of chronic intermittent rectal prolapse requiring… Continue Reading

Laparoscopic Sigmoid Resection for All Patients Who Present with Complicated Diverticulitis and Fistula Formation
Purpose: Traditionally, complicated diverticulitis with fistula formation was thought to be a contraindication to performing laparoscopic sigmoid resection and was performed with an open procedure. As experience in laparoscopic surgery increased, more complex surgery was performed laparoscopically in selective patients. Since 2004, our institution has been offering laparoscopic colectomy to all elective patients presenting with… Continue Reading

Laparoscopic Sigmoidectomy and Anastomotic Leak
This video demonstrates a laparoscopic approach to complex diverticulitis, as well as post-operative anastomotic leak. The patient is a 43 year-old morbidly obese male (BMI 48) who developed diverticulitis with a 9cm intra-abdominal abscess. Despite percutaneous drainage, the patient had continued sepsis requiring surgery. The patient underwent a hand-assist sigmoid resection. This video highlights techniques… Continue Reading

Laparoscopic Single-Access Appendectomy
Background: Natural orifice transluminal endoscopic surgery (NOTES) has been proven to be technically feasible in animal models but still has significant limitations for human application. Single-access transabdominal surgery is a competing alternative which obviates the need for multiple incisions. Looking to minimize the operative trauma and following NOTES principles, we used the umbilicus, an existing… Continue Reading

Laparoscopic Single Port Appendectomy Using Intraperitoneally Placed Magnetic Camera
Single Port Appendectomy has been described. One of the problems of single port surgery is that there are limited valves for insertion of instruments and that the instruments tend to clash with the camera outside as the point of ingress is the same. Caddedu and colleagues have been working on a magnetic camera that can… Continue Reading

Laparoscopic Skill Acquisition with Lap Sim®virtual Simulators: A Comparative Study
Objectives: Virtual simulators have been validated as training tools for development of laparoscopic skills and as an instrument of discrimination between novice and senior surgeons. Whilst formal training programs for inexperienced surgeons are lacking; there is no information about the use of these simulation devices in order to obtain optimal results.Material and methods: We present… Continue Reading

Laparoscopic Skills Acqusition in a Short Term Structured Training for Laparoscopic Cholecystectomy in a Phantom Model Using Porcine Gall Bladder
IntroductionLaparoscopic skills training outside the operating room is becoming the standard for educating surgical residents. There are various methods of training outside the operation theatre ranging from inanimate models, virtual simulation and training on cadavers. The best method of training has not yet been well established. This study prospectively evaluates the laparoscopic skills acquisition in… Continue Reading
