Usually, sphincter defects are in the anterior position on the sphincter, when an anterior sphincteroplasty may be carried out. Where the sphincter defect is laterally or posteriorly placed, this carries a less successful outcome. [3] [4] [5] Overlapping anterior sphincteroplasty is preceded by a bowel preparation and possibly antibiotics. Once ...
Dennis L. Fowler is the Vice President and Medical Director for Perioperative Services at NewYork-Presbyterian Hospital/Columbia University Medical Center.He is a pioneer in the field of endoscopic surgery and has been the first to perform numerous innovative laparoscopic surgical procedures, never before accomplished (NYP).
Lateral internal sphincterotomy is the preferred method of surgery for persons with chronic anal fissures, and is generally used when medical therapy has failed. [1] It is associated with a lower rate of side effects than older techniques such as posterior internal sphincterotomy and anoplasty, [3] and has also been shown to be superior to topical glyceryl trinitrate (GTN 0.2% ointment) in ...
End-to-end sphincteroplasty is shown to have a high failure rate in 1940. In AD 1971, Parks and McPartlin first describe an overlapping sphincteroplasty procedure. Biofeedback is first introduced in 1974. [71] In 1975, Parks describes post anal repair, a technique to reinforce the pelvic floor and EAS to treat idiopathic cases.
Biliary endoscopic sphincterotomy is a procedure where the sphincter of Oddi and the segment of the common bile duct where it enters the duodenum are cannulated and then cut with a sphincterotome, a device that includes a wire which cuts with an electric current (electrocautery).
Perineoplasty (also perineorrhaphy) denotes the plastic surgery procedures used to correct clinical conditions (damage, defect, deformity) of the vagina and the anus. [1] [2] [3] Among the vagino-anal conditions resolved by perineoplasty are vaginal looseness, vaginal itching, damaged perineum, fecal incontinence, genital warts, dyspareunia, vaginal stenosis, vaginismus, vulvar vestibulitis ...
Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. [1]
The system allows an endoscopist to access walled-off necrosis and symptomatic pancreatic pseudocysts by means of a transduodenal or a trans gastric approach to then place the AXIOS stent. [49] This was the first system of its kind in the United States and is currently the only minimally invasive approach that entirely streamlines the process ...
