[Laparoscopic cystoprostatovesiculectomy and ureterosigmoidostomy. Experimental surgical model].
The authors have performed 26 experimental laparoscopic cystoprostatovesiculectomies in pigs, 17 of which were followed by ureterosigmoidostomies, also laparoscopically. Using a 10 mm trocar at the umbilical level (optics), another 10 mm at the hypogastric level (pliers and titanium staple applicator), a third 5 mm in left iliac fossa (pliers) and another 5 mm in right iliac fossa (electric shears), cystectomy is performed with a routine technique: stapling and section of deferents, umbilical arteries, vesical lateral pedicles and prostate-seminal pedicles. A double ligature precedes the section of the urethra in the pelvian fundus. A plier passed within an Amplatz jacket (previously introduced through the anus) assists the laparoscopic ureterosigmoidostomy "in elephant trunk" which is performed by sero-muscle suture using 3-zero reabsorbable single-strand material. Overcoming the anatomical differences existing with humans, the illustrated experimental model confirms the possibility of performing this type of procedures in human beings, which would considerably curtail the morbidity associated with this type of surgery.
