Acute Abdomen Secondary to a Spontaneous Perforation of the Biliary Tract, a Rare Complication of Choledocholithiasis.

INTRODUCTION: The spontaneous perforation of the biliary tract (SPBT) is an extremely rare cause of peritonitis, which was first described by Freeland in 1982, to date only around 70 cases have been reported. Here we present a case of spontaneous perforation of the biliary tract, in a patient with choledocholithiasis, which was treated with ultrasound-guided drainage and ERCP. CASE REPORT: A 51-year-old male was admitted to the emergency room for 15-day evolution jaundice, localized pain in the right flank and hypochondrium of 3days. He had a history of cholecystectomy 15 years ago and 4 episodes of cholangitis, the last one in 2015. A magnetic resonance imaging (MRI) was performed, that showed evidence of choledocholithiasis, in addition to a possible biliary leakage. The patient was treated with ultrasound-guided drainage and ERCP successfully. DISCUSSION: Spontaneous perforation of the biliary tract is a disease entity in which wall of the extrahepatic or intrahepatic duct is perforated without any traumatic or iatrogenic injury. The clinical presentation varies from nonspecific abdominal pain to biliary peritonitis, in most of the cases forming bilomas. Universal management involves decompression of the biliary tree and repair of the leak site. CONCLUSION: The spontaneous perforation of the biliary tract is a disease that represents a diagnostic challenge. The treatment in the patients with SPBT is not well established and has to be individualized for each case, depending on the history of the patient, the site of perforation, the time of evolution, the suspicion of infection, and the patient status.

A rare case of subacute appendicitis, actinomycosis as the final pathology reports: A case report and literature review.

INTRODUCTION: Acute appendicitis is the most common indication for an emergency abdominal surgery in the world, with a lifetime incidence of around 10%. Actinomycetes are the etiology of appendicitis in only 0.02%-0.06%, having as the final pathology report a chronic inflammatory response; less than 10% of the cases are diagnosed before surgery. Here, we present the case of a subacute appendicitis secondary to actinomycosis. CASE REPORT: A 39-year-old male presented with a twelve-day evolution of intermittent abdominal pain in the right lower quadrant, treated at the beginning with ciprofloxacin and urinary analgesic. The day of the admission he referred intense abdominal pain with nausea. An open appendectomy was preformed, finding a tumor-like edematous appendix with a diameter of approximately 2.5cm. DISCUSSION: Actinomyces are part of the typical flora of the oral cavity, gastrointestinal tract and vagina. The predominant form of human disease is A. Israelii, it requires an injury to the normal mucosa to penetrate and cause disease. Abdominal actinomycosis involves the appendix and caecum in 66% of the presentations, of these, perforated appendicitis is the stimulus in 75% of the cases. A combination of antibiotic therapy and operative treatment resolves actinomycosis in 90% of cases. CONCLUSION: Abdominal actinomycosis is an uncommon disease been the common presentation a perforated appendicitis, here we present a less common presentation of it with a non-perforated appendix.
