Single-Incision Multiport Laparoendoscopic (SIMPLE) Cholecystectomy

Published: April 2010 - Surgical Endoscopy
Authors: Bruce M. Molinelli, Athanassios Petrotos
Excerpt: "We have moved from a three-port trocar technique to a more stable and flexible port platform (GelPOINT; Applied Medical, Rancho Santa Margarita, CA, USA), which allows the insertion of multiple ports. We continue to use straight instruments preferentially, with occasional need for a right-angled instrument and even less need for articulating instruments... We have since found that the GelPoint system allows for much more freedom of movement through the same small skin incision."

Single-Incision Laparoscopic Colectomy: Outcomes of an Emerging Minimally Invasive Technique

Published: March 2011 - International Journal of Colorectal Disease
Authors: Diego I. Ramos-Valadez, Chirag B. Patel, Madhu Ragupathi, Malak B. Bokhari, T. Bartley Pickron, Eric M. Haas
Excerpt: "We have since gained experience with the Gelpoint device and found it more advantageous for colorectal procedures. Its high outer profile allows use of four or even five trocars with varying degrees of separation to limit clashing and allowing for ample counter traction when needed. In addition, a built in wound protector not only prevents direct contact between the specimen and the abdominal wall, but also secures the port in patients with a high BMI or thick abdominal wall."

Single Incision ("Scarless") Laparoscopic Total Abdominal Colectomy with End Ileostomy for Ulcerative Colitis

Published: February 2011 - Journal of Gastrointestinal Surgery
Authors: Alessandro Fichera, Marco Zoccali, Roberto Gullo
Excerpt: "In all cases, a GelPOINT Advanced Access Platform (Applied Medical, Rancho Santa Margarita, CA) was employed as sole access to the abdominal cavity. Its GelSeal cap provides additional outer working space and the ability to achieve tissue triangulation even with the standard laparoscopic instrumentation that we routinely use."

Single Incision Laparoscopic Total Abdominal Colectomy with Ileorectal Anastomosis for Synchronous Colon Cancer

Published: May 2010 - Techniques in Coloproctology
Authors: O. Bardakcioglu, S. Ahmed
Excerpt: "All retraction could be adequately achieved using a single instrument through the GelPoint device and patient positioning. The advantage of the GelPoint device as compared to other single port access devices is that a variable incision size from 2-4 cm can be used depending on the size of the extracted colon."

Transumbilical Sleeve Gastrectomy with an Accessory Lateral Port: Surgical Results in 237 Patients and 1-Year Follow up

Published: November 2012 - Obesity Surgery
Authors: Carlos Farias, Jose Ignacio Fernandez, Cristian Ovalle, Carolina Cabrera, Jaime de la Maza, Karin Kosiel, Ana Maria Molina

"We initially used SILS (Covidien) but converted to GelPoint (Applied Medical), which is currently our standard single-port device for all transumbilical procedures."

"The presented technique uses the transumbilical approach as the primary means of intra-abdominal access with a 5-mm assistance trocar. Although this technique does not correspond to pure SILS, this technique achieves all of the cosmetic advantages of the single-incision approach and adds better instrument triangulation as well as very good visualization and exposure."

Laparoendoscopic single-site surgery (LESS) in gynecology: a multi-institutional evaluation

Published: November 2010 - American Journal of Obstetrics and Gynecology
Authors: Amanda Nickles Fader, MD; Luis Rojas-Espaillat, MD; Okechukwu Ibeanu, MD; Francis C. Grumbine, MD; Pedre F. Escobar, MD
Excerpt: "Conclusion: LESS is feasible, safe, and reproducible in gynecology patients with benign and cancerous conditions. Operative times are reasonable and can be decreased with experience."

Single Incision Prone Retroperitoneoscopic Paediatric Nephrectomy

Published: May 2015 - Journal of Pediatric Urology
Authors: Neil C. Featherstone, Gunter De Win, Shabnam Undre, Abraham Cherian

“We have found that the advanced access platform (GelPOINT Mini) facilitates triangulation and that flexible instrumentation was not necessary.”

“LESS nephrectomy is feasible from infants to adolescents and can be taught to senior trainees with existing conventional laparoscopic experience.”

Is Right-Sided Laparoendoscopic Single-Site Donor Nephrectomy Feasible?

Published: June 2011 - Journal of Urology
Authors: Cheguevara Afaneh, Ranjith Ramasamy, David B. Leeser, Sandip Kapur, Joseph J. Del Pizzo

"Although technically challenging, LESS-RDN in experienced hands can be performed safely and should be considered as an alternative if it is the preferred kidney for transplantation."

"The GelPOINT device with 3 trocars is inserted into the abdomen and pnuemoperitoneum is established."

"Standard nonarticulating laparoscopic instruments are used in most of the procedure."

"The LESS-RDN surgical technique essentially duplicates standard LDN."

Laparoendoscopic Single Site Live Donor Nephrectomy: Initial Experience

Published: November 2010 - Journal of Urology
Authors: Gimenez E, Leeser DB, Wysock JS, Charlton M, Kapur S, Del Pizzo JJ
Excerpt: "The use of a specialized umbilical multichannel port may confer specific advantages to the surgeon. In this series the GelPOINT provided greater space for triangulation and, thus, decreased instrument clashing. It also allows easy, rapid modification of port configuration during the procedure, which aids in improving dissection and retraction ergonomics. In this series no extra-umbilical incisions were needed."

Laparoendoscopic Single-Site (LESS) Surgery Versus Conventional Laparoscopic Surgery: Comparison Of Surgical Port Performance in a Surgical Simulator with Novices

Published: December 2010 - Surgical Endoscopy
Authors: Bernadette Brown-Clerk, Adam E. de Laveaga, Chad A. LaGrange, Laura M. Wirth, Bethany R. Lowndes, M. Susan Hallbeck
Excerpt: "Overall, the TriPort may be more challenging for novices to use in learning the LESS procedure than either the SILS port or the GelPOINT system. The GelPOINT system may offer the most consistent platform for LESS performance and novice skill acquisition."
