This report presents two rare cases of gallbladder rupture in dogs with small gallbladders that did not result in bile leakage and their subsequent surgical treatment. The report includes a 5-year-old spayed female Chihuahua weighing 3.5 kg and a 9-year-old castrated male Poodle weighing 5.3 kg. Both dogs had elevated liver enzyme levels on blood chemistry. However, only the second dog (2) (Poodle) presented with hyperbilirubinemia and jaundice, whereas the first dog (Chihuahua (1)) did not display any specific clinical signs. Diagnostic imaging revealed a small gallbladder in both dogs, and the dogs were diagnosed with cholecystolithiasis (1) and extrahepatic biliary tract obstruction (2). No bile leakage-related abdominal effusion was observed. Gallbladder rupture and adhesion to the adjacent tissues were confirmed during cholecystectomy.

Purpose: Although an increased incidence of gallbladder (GB) stone formation after gastrectomy has been reported, its etiology remains uncertain. The goal of this study was to explore the incidence of gallstone formation after gastrectomy in gastric cancer patients and investigate the risk factors therein. Materials and Methods: Medical records of patients who underwent curative gastrectomy, performed by a single surgeon between August 2012 and December 2015 at the Asan Medical Center, were retrospectively reviewed. Baseline characteristics and surgical outcomes, including GB stone gallstone formation after gastrectomy, were analyzed. Results: Of 561 patients included in the study, 36 presented with GB stone formation after gastrectomy for gastric cancer. The incidence of gallstone formation was 6.4%. The mean interval between gallstone formation and gastrectomy was 21.9 months. In multivariate analyses, the incidence of gallstone formation increased in patients 63 years or older, with greater than 6.2 kg weight loss in the first 6 months after the procedure, a preoperative serum total bilirubin level greater than 0.5 mg/dL, and in patients who did not receive adjuvant chemotherapy. Conclusions: This study presented risk factors for GB stone formation after gastric cancer surgery, and special attention should be afforded to patients with such risk factors.
