English to Italian Medical Medical (general) chirurgia

Si tratta di un manuale americano di chirurgia, capitolo sul sistema biliare.
In questo paragrafo analizza la colangite piogenica ricorrente, presentazione e trattamento.
Trovo queste frasi:

The variability of presentation and location of disease has spurred the development of a number of operations to achieve these goals. The presence of intrahepatic strictures connotes a complicated case and may warrant resection, stricturoplasty, or hepaticocutaneous jejunostomy. When clearance of all stones is not possible or future need for endoscopic therapy is anticipated, the terminal end of the Roux limb for a hepaticojejunostomy can be brought out as a stoma to provide easy access for choledochoscopy.

Stricturoplastica?? Vedo che esiste in italiano ma non capisco se va bene per questo contesto...
Grazie mille.
