Real-time Intraoperative Detection of Tissue Hypoxia in Endoscopic Gastrointestinal Surgery By a Novel Wireless Pulse Oximeter (wipox)
ObjectiveDehiscence or leakage following bowel anastomoses occurs at a rate of 0-50% with a high associated mortality. Vascular perfusion and tissue oxygenation (SpO2) at the anastomotic site are fundamental determinates of anastomotic viability. We aimed to construct a wireless pulse oximeter (WiPOX) to monitor intraoperative real-time tissue oxygenation, permitting the identification of unrecognized compromised blood… Continue Reading
Single-incision Laparoscopic Cholecystectomy in Modified Lithotomy Position – Improved Ergonomics for Surgeons and Surgical Assistants
INTRODUCTION – Most single-incision laparoscopic cholecystectomy procedures described to date were done with the patient in supine position. Although convenient for the operating surgeon (standing on the patient’s left), we found this position to be taxing on a surgical assistant (who stands on the patient’s right). To alleviate the strain on the assistant’s back we… Continue Reading

Single-incision Laparoscopic Cholecystectomy Using Novel Powered Articulating Instruments (terumo)
Introduction: Single-incision laparoscopic surgery (SILS) has emerged as a promising way to perform laparoscopic surgery less invasively. Currently, most SILS procedures are performed using standard laparoscopic instruments. This video demonstrates the use of novel powered articulating instruments to perform a SILS cholecystectomy in a cadaver. Methods: SILS cholecystectomy was performed through an umbilical incision in… Continue Reading
Single Port Access Surgery: Performance Difficulty and a Possible Solution
Introduction: During single port access surgery (SPA), surgeons often find it difficult to triangulate their instruments to the target organ. Their hand movements are limited by the single port access to the abdominal cavity. The first goal of this study is to quantify the level of difficulty in performing a SPA procedure as compared to… Continue Reading

Single Site Laparoscopic (ssl) Cholecystectomy in Human Cadavers Using Novel Percutaneous Retraction and a Magnetic Anchoring and Guidance System (mags): Re-establishing the Critical View
Introduction: SSL, though promising, introduces ergonomic challenges due to loss of instrument triangulation as obtained in conventional laparoscopy. This limitation makes establishing the critical view during dissection of the Triangle of Calot (TOC) difficult and has resulted in a variety of strategies to overcome the problem. This study investigates use of a novel percutaneous grasper… Continue Reading
Use of a Novel Percutaneous Retraction Device and Magnetic Anchoring and Guidance System (mags) Helps Re-establish the Critical View and Improves Surgeon Performance While Mimicking the Four Port Technique in Single Site Laparoscopic (ssl) Cholecystectomy
Introduction: SSL, though promising, introduces ergonomic challenges due to loss of instrument triangulation as obtained in conventional laparoscopy. This limitation makes establishing the critical view during dissection of the Triangle of Calot (TOC) difficult and has resulted in a variety of strategies to overcome the problem.

Use of a Novel, Self-contained Tissue Retraction Device to Reduce Trocar Site Number in Laparoscopic and NOTES-based Surgical Procedures
In an effort to make laparoscopic surgical procedures even less invasive, single port access and natural orifice transgastric endoscopic surgical (NOTES) approaches have been developed over the past several years. However, the need to maintain basic surgical working principles, such as proper tissue retraction to create tension and counter-tension, is still of critical importance if… Continue Reading
