Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Summary

Surgical outcomes for feline extra-hepatic biliary obstruction (EHBO) are poor. Pre-operative jaundice and post-operative low blood pressure predict worse survival, while inflammatory causes offer a better prognosis than cancer.

Area of Science:

  • Veterinary Surgery
  • Canine and Feline Medicine
  • Surgical Oncology

Background:

  • Feline extra-hepatic biliary obstruction (EHBO) presents significant surgical challenges with limited reported survival data.
  • Identifying prognostic factors is crucial for improving outcomes in cats with EHBO.

Purpose of the Study:

  • To investigate the etiology and clinical findings associated with feline EHBO.
  • To determine the influence of these factors on short-term (2 weeks-6 months) and long-term (>6 months) survival.

Main Methods:

  • Retrospective observational study of 26 cats undergoing surgery for EHBO between 2012 and 2020.
  • Analysis of etiological factors (inflammatory, neoplastic, foreign body) and clinical parameters.
  • Evaluation of short- and long-term survival rates and median survival time (MST).

Main Results:

  • Inflammatory causes (14/21) were more common than neoplastic (6/21).
  • Pre-operative hyperbilirubinemia and post-extubation hypotension were linked to reduced survival.
  • Short-term survival was 17/26 cats, long-term survival 13/26 cats. MST was 86 days.
  • MST for neoplastic EHBO was 17 days vs. 1165 days for inflammatory causes.

Conclusions:

  • Pre-operative hyperbilirubinemia and post-operative hypotension are potential negative prognostic indicators for feline EHBO surgery.
  • Inflammatory causes of EHBO are associated with a more favorable prognosis compared to neoplastic causes.
  • Further research is needed to validate these prognostic associations.
