NOTES Nephrectomy: Searching for the Best Path
Introduction:Laparoscopic nephrectomy is replacing open radical nephrectomy as the standard of care and it can be performed by a transperitoneal and retoperitoneal approach.Data remain scanty as to whether any objective difference exists between the two approaches.NOTES may shift the decisional paradigm between the two techniques.In the attempt to establish the best way to approach the… Continue Reading

NOTES Retroperitoneal Transvaginal Total and Partial Right Nephrectomy
IntroductionAdvantages of transperitoneal and retroperitoneal laparoscopic nephrectomy in comparison to open nephrectomy are well established. The vagina is a viable route for kidney retrieval following laparoscopic nephrectomies. Conceivably, nephrectomy performed through a natural orifice could enhance cosmesis and patients recovery.Aim: to explore trans-vaginal retroperitoneal NOTES total and partial nephrectomy in the porcine model.Materials and methodsTotal… Continue Reading

NOTES Specimen Retrieval Using Novel Endoscopic Instrumentation
INTRODUCTION: Currently, there is no ideal specimen retrieval bag for NOTES. This study tested the efficacy and reliability of a novel through-the- scope (TTS) retrieval bag.METHODS: Eleven NOTES retrieval bags (Ethicon Endo Surgery) 5.5x2.5cm in size and 3.6mm in diameter were used for these experiments. The impermeable bags have a 3.5cm wire-supported articulating/rotating opening with… Continue Reading

NOTES Transgastric Cholecystectomy: One-year Follow-up
OBJECTIVE: Natural orifice translumenal endoscopic surgery (NOTES) is still a new and investigative technique. To date, published short-term outcomes have been promising. Little is known about the long term effects of novel access routes for standard surgeries. Here we present long-term data of the first human transgastric cholecystectomies performed one year ago. METHODS: Four patients… Continue Reading

Novel Approach to NOTES Gastrotomy Creation Using the Endoscopic Cap Suction Technique
BACKGROUND: Numerous methods have been described for gastrotomy creation during Natural Orifice Translumenal Endoscopic Surgery (NOTES). These techniques are often blind, difficult to perform, or require temporary placement of a gastrostomy tube. The objective of this study is to create a safer method of NOTES gastrotomy creation.METHODS: A novel endoscopic cap suction technique was used… Continue Reading

Novel System Improves Accuracy of Needle Placement for Ablation Procedures
This study demonstrates improved accuracy in needle placement for ablation procedures using a novel 3D ultrasound trajectory system. Ultrasound guidance can be difficult and require years of experience to master. In addition it does not provide a real time trajectory to the target. This system creates an advanced, real-time stereoscopic image when added to standard… Continue Reading

Objective Mapping of the Anal Sphincter Complex Using 3-d Endoanal Ultrasound
Introduction: Despite the subjectivity of the method, endoanal ultrasonography (EAUS) is the gold standard to evaluate the external (EAS) and Internal (IAS) anal sphincters. Differentiating a sphincter defect from normal anatomic variation is challenging. We developed a new standardized protocol to evaluate the anal sphincter complex and establish normal values of lengths and thickness of… Continue Reading

Old Age Does Not Affect Outcomes of Laparoscopic Esophagomyotomy and Dor Fundoplication for Achalasia
Introduction: The effectiveness of esophagomyotomy for improving swallowing in elderly patients with achalasia compared with younger ones has been questioned. This study was designed to provide an answer. Methods: 139 consecutive patients with esophageal achalasia who underwent laparoscopic esophagomyotomy and Dor fundoplication and who were available for telephone interview were divided into two groups by… Continue Reading

Oncologic and Perioperative Outcomes of Hand-Assissted Laparoscopic Surgery (hals) Vs Open Low Rectal Cancer Resection: A Case Match Study.
Purpose: Hand-assisted laparoscopic colorectal resection, the non-dominant hand in the pelvis has been believed as the major obstacle and may be the cause of difficulties and longer the operative time compares to open procedures. Hand-assissted laparoscopic colorectal resection was found to be associated with less postoperative pain, faster return to bowel function, and shorter hospital… Continue Reading

One Year Symptom Scores After Laparoscopic Anti-reflux Surgery: Is There a Learning Curve?
Introduction: Laparoscopic anti-reflux surgery is the gold standard for surgical treatment of GERD and a well defined learning curve for the procedure has been described. Aim of this study is to assess if the surgeons experience has an effect on one year symptom scores and patient satisfaction.Methods: All patients undergoing anti-reflux surgery are entered into… Continue Reading

Open or Laparoscopic Resection of Paraganglioma? a Comparison to Adrenal Pheochromocytoma in the Laparoscopic Era
Introduction: Laparoscopic adrenalectomy (LA) has become the standard for removal of most adrenal pheochromocytomas (pheos). However, laparoscopic (LAP) resection of extra-adrenal pheos or paragangliomas has been reported only anecdotally. This study investigates the results of resection of paragangliomas in the laparoscopic era.Methods: A retrospective record review of all patients who underwent resection of intra-abdominal paragangliomas… Continue Reading

Opportunity Cost in the Evaluation of Surgical Innovations: A Case Study of Laparoscopic Versus Open Colectomy
Introduction Opportunity cost is the value of an activity forgone to participate in some other activity. With respect to surgery, an innovation incurs an opportunity cost when it uses additional operating time that could otherwise be used in a productive way. Although fundamental to the economist’s view of costs, opportunity cost is infrequently used in… Continue Reading
