title: A comparison of the Monti and Casale (spiral Monti) procedures.
abstract: OBJECTIVE
  We present our long-term followup and comparison of outcomes between the Monti and Casale (spiral Monti) procedures in a large group of children and young adults.
  
  
  METHODS
  A retrospective chart review was done, including all patients undergoing the Monti or Casale procedure at our institution with a minimum followup of 6 months. Age at surgery, the bowel segment used, stomal location, the number and type of revisions or endoscopic procedures required after channel creation, problems catheterizing and channel continence were documented, and a database was created.
  
  
  RESULTS
  Of 188 patients identified with at least 6 months of followup 109 underwent a Monti procedure, while 79 underwent a Casale procedure. Patient age at surgery was 10 months to 31 years (mean 10.2 years). Mean followup was 43 months for the entire cohort, and 47.2 and 37.2 months for the Monti and Casale groups, respectively. A total of 43 open revisions were required in 36 patients (19.1%). Stomal revisions accounted for 18 procedures, while subfascial revisions accounted for 25 in 17 (9.0%) and 21 (11.2%) patients, respectively. A total of 21 endoscopic procedures requiring anesthesia were performed in 17 patients (9.0%). In the Monti group stomal revision was required in 11 patients (10.1%), while subfascial revisions were required in 9 (8.3%). In the Casale group stomal revision was required in 6 patients (7.6%), while subfascial revisions were required in 12 (15.2%). Of the channels 98% were completely continent at the stoma.
  
  
  CONCLUSIONS
  In a large population of children and young adults we report durable and reliable long-term results with the Monti and Casale procedures, including continence at the stoma. The only significant difference noted between the 2 procedures was a higher incidence of subfascial revisions for umbilical stomas in each group. The need for subfascial revision is highest in spiral Monti channels placed in the umbilicus.
