Synchronous Acute Appendicitis and Cholecystitis in a Paediatric Patient with Salmonella Enteritis

We present the case of a 13-year-old male who presented with right upper quadrant pain and diarrhoea after recently travelling from Bali, Indonesia. He had a normal white cell count of 8x10^9/L and elevated c-reactive protein (CRP) of 205 mg/L with normal liver function tests. Originally thought to be appendicitis, given the rarity of cholecystitis in a child, he was commenced on broad-spectrum antibiotics and was taken to the operating theatre based on his clinical presentation. Diagnostic laparoscopy revealed inflammatory change in both the gallbladder and appendix and a laparoscopic cholecystectomy and appendicectomy were performed simultaneously. Histopathology results confirmed cholecystitis and appendicitis and a stool culture confirmed the presence of Salmonella serotype B. Synchronous cholecystitis and appendicitis is an exceedingly rare phenomenon with only a handful of cases reported in the literature. This is the first case in the literature of this phenomenon occurring in the paediatric population; surgeons need to be aware of this rare possibility even in the paediatric population and especially in those patients with an atypical presentation or in recent travellers experiencing gastroenteritis.
