- A new large-caliber trocar for percutaneous endoscopic gastrostomy by the introducer technique in head and neck cancer patients(2011) GIORDANO-NAPPI, J. H.; MALUF-FILHO, F.; ISHIOKA, S.; HONDO, F. Y.; MATUGUMA, S. E.; LIMA, M. Simas de; SANTOS, M. Lera dos; RETES, F. A.; SAKAI, P.Background and study aims In many patients, percutaneous endoscopic gastrostomy (PEG) can be limited by digestive tract stenosis. PEG placement using an introducer is the safest alternative for this group of patients, but the available devices are difficult to implement and require smaller-caliber tubes. The aim of this study was to evaluate the modification of an introducer technique device for PEG placement with regard to the following: procedure feasibility, possibility of using a 20-Fr balloon gastrostomy tube, tube-related function and problems, complications, procedure safety, and mortality. Patients and methods Between March 2007 and February 2008, 30 consecutive patients with head and neck malignancies underwent introducer PEG placement with the modified device and gastropexy. Each patient was evaluated for 60 days after the procedure for the success of the procedure, infection, pain, complications, mortality, and problems with the procedure. Results The procedure was successful in all cases with no perioperative complications. No signs of stomal infection were observed using the combined infection score. The majority of patients experienced mild-to-moderate pain both in the immediate postoperative period and at 72 hours. One major early complication (3.3%) and two minor complications (6.7%) were observed. No procedure-related deaths occurred during the first 60 days after the procedure. Conclusion The device modification for PEG using the introducer technique is feasible, safe, and efficient in outpatients with obstructive head and neck cancer. In this series, it allowed the use of a larger-caliber tube with low complication rates and no procedure-related mortality.
- Comparison of electrical current and ultrasonic device for incision of the septum of the pharyngoesophageal diverticulum in a pig model(2015) HONDO, Fabio Yuji; GIORDANO-NAPPI, Jose Humberto; PESSORRUSSO, Fernanda Cristina Simoes; FRANCO, Matheus Cavalcante; NEVES, Carla Zanelatto; CECCONELLO, Ivan; SAKAI, Paulo; MALUF-FILHO, FauzeComplications of endoscopic treatment of pharyngoesophageal diverticulum (PED) such as bleeding and perforation occur in up to 15 % of cases. Our objective was to compare incision of the PED septum using the ultrasonic device (group H) with incision using electrical current (group M) in a pig model. Twenty domestic pigs were divided into groups H and M. The incision of the PED septum was performed using the ultrasonic device or using electrical current, respectively. The procedural time, complication rate, length of the border of the incised septum, and thermal tissue damage were compared between groups. Mean time to divide the septum and total procedure time were significantly shorter in group H. Mean length of the border of the incised septum was significantly higher in group H. The lateral thermal spread caused by electrical current (group M) was more intense. Hemorrhage was exclusively observed in group M. Experimental endoscopic diverticulotomy using ultrasonic device was faster and caused less tissue damage when compared to electrical current.
