Objectives: To use three-dimensional anorectal ultrasonography (3D-US) to evaluate the outcome of ligation of the intersphincteric fistula tract (LIFT) in patients with crypto-glandular transsphincteric fistula and describing the patterns of healing, failure, and recurrence rate.
Methods: After classifying the fistula and determining the length of the sphincter muscle to be transected, the patients were submitted to LIFT. The accuracy of pre- and postoperative 3D-US with 360° endoprobe (16 MHz) with automatic scanning and clinical findings was evaluated against surgical findings.
Introduction: 3-dimensional printing has enabled the development of unique and affordable additive manufacturing, including the prototyping and production of surgical forceps. Objective: demonstrate the development, 3D printing and mechanical-functional validation of a laparoscopic grasping forceps.
Methods: the clamp was designed using a computer program and printed in 3 dimensions with polylactic acid (PLA) filament and added 5 screws for better leverage.
Background: Paracentesis is a routine medical procedure quite relevant in clinical practice. There are risks of complications related to paracentesis, so it is essential a proper trainee for the younger practicer.
Objective: The article describes the construction and the application of a low cost paracentesis simulator for undergraduate medical students and it also describes the perception of students about the simulator as well.
Background: Three-dimensional videosurgery is already a reality worldwide. The trainee program for this procedure should be done initially and preferably in simulators.
Aim: Assemble low-cost simulator for three-dimensional videosurgery training.
