“…Previous studies have shown PTT times, serum concentrations of albumin, globulin, and bilirubin, percentage of band neutrophils, and total lymphocyte counts to also be risk factors for death 10,12,13 In the same studies, reported preoperative risk factors for death in dogs undergoing biliary surgery include age, preanesthetic heart rate, blood urea nitrogen, serum creatinine, GGT, phosphorus, and bilirubin values. 10,12 The risk of death in our dogs increased 0.3 times (30%) for each increment in lactate concentration elevation in the postoperative period. Serum lactate concentrations have been previously investigated in dogs as a significant negative prognostic indicator in disease processes such as gastric dilatation and volvulus, and babesiosis.…”

“…7,9 Although the reported perioperative mortality ranges from 21.7% to 40%, 1,2,8 the prognosis for a dog with GM undergoing cholecystectomy is generally favorable if the dog survives the immediate postoperative period. 1,2,[10][11][12] Long-term outcome for dogs surviving surgery and the immediate postoperative period is good with 1 study reporting both 1-and 2-year survival rates of 22 of 34 (66%). 10 Our objectives were to report the clinical and intraoperative findings in dogs with GM undergoing cholecystectomy and to determine prognostic factors.…”

Clinical Findings and Prognostic Factors for Dogs Undergoing Cholecystectomy for Gall Bladder Mucocele

et al. 2013

Objective: To report clinical findings and explore prognostic factors for dogs that had cholecystectomy for gall bladder mucocele. Study Design: Retrospective case series. Animals: Dogs (n = 43) with gall bladder mucoceles. Results: Diagnosis of gall bladder mucoceles was confirmed by histopathology and 74% were diagnosed based on preoperative abdominal ultrasonography. Intraoperative evidence of gall bladder rupture was noted in 10 dogs (23%), and 16 (37%) had evidence of previous leakage in the abdominal cavity. One dog had positive bacterial growth from the gall bladder content. The most common histopathologic findings in liver biopsies obtained at surgery were cholangiohepatitis, biliary hyperplasia, or cholestasis. Univariate analysis showed evidence of postoperative hypotension (P = .05) to be significantly negatively associated with survival. Significant difference in mean postoperative serum lactate (P = .034) and postoperative packed cell volume (P = .063) between dogs that survived and died was also noted. Conclusions: Elevations in postoperative serum lactate concentrations and immediate postoperative hypotension in dogs undergoing cholecystectomy for gall bladder mucoceles are associated with poor clinical outcome.Although a recognized disease process for several decades, the incidence of gall bladder mucoceles (GM) in dogs appears to be increasing.

“…The main risk factors for the development of gallstones in humans are age, heredity, parity and obesity; occurring mainly in people over 55 years, and a greater incidence among women [5][6][7][8] . There are several conditions that, in humans and animals, can cause obstruction in the biliary tree, occurring cholestasis [9][10][11][12][13] . However, in recent years, there was an increase in the diagnosis of asymptomatic lithiasis due to upgrading diagnostic methods routinely performed in patients [14][15][16][17] .…”

Comparative study between ligature with thread or metallic clamping by means of laparoscopy with the purpose of experimental biliary obstruction in swines

et al. 2011

PURPOSE: To induce a total extra-hepatic obstructive jaundice in swines, by ligation of the common bile duct by laparoscopic surgery. METHODS: Eight swines of the Landrace race, 36-day-old, originated from the same matrix, distributed in two groups. Group A: was used titanium metal clip to the common bile duct ligation in three animals; group B: were ligated with 2-0 cotton thread in five animals. RESULTS: The ligation of the biliary ducts was performed successfully in all animals, with easy identification of the common bile duct by laparoscopy. There weren't difficulties in the procedures, mainly due to the increased surgical field provided by the excellent quality of light and image of the appliance. The clinical signs of jaundice were evident in the animals in seven days. In group A, two animals showed bile duct perforation near the clip, probably due to ischemic necrosis, progressing to peritonitis and death. In group B, five animals showed obstructive jaundice without any amendment. CONCLUSION: Under the conditions of this study, we therefore recommend the use of unabsorbed wires to experimental biliary obstruction, in order to avoid complications, such as ischemia and necrosis, followed by perforation of the wall of the bile ducts.

“…Those findings will be used in successive experiments with prolonged time of postoperative histopathological evaluation to determine the character of bile-induced changes in the jejunal mucosa (Amsellem et al 2006). In clinical patients (cats and dogs), cholecystoenterostomy is usually the only form of treatment during surgical interventions (Tangner 1984).…”

The use of shape memory compression anastomosis clips in cholecystojejunostomy in pigs – a preliminary study

et al. 2015

View full text Add to dashboard Cite

This paper reports on the use of compression anastomosis clips (CAC) in cholecystoenterostomy in an animal model. Cholecystojejunostomy was performed in 6 pigs using implants made of nickel-titanium alloy in the form of elliptical springs with two-way shape memory. The applied procedure led to the achievement of tight anastomosis with a minimal number of complications and positive results of histopathological evaluations of the anastomotic site. The results of the study indicate that shape memory NiTi clips are a promising surgical tool for cholecystoenterostomy in cats and dogs.
