Acute acalculous cholecystitis is traditionally associated with elderly or critically ill patients.
We present the case of an otherwise healthy 23-year-old Caucasian man who presented with acute right-sided abdominal pain. An ultrasound examination revealed evidence of acute acalculous cholecystitis. A laparoscopy was undertaken and the dual pathologies of acute acalculous cholecystitis and acute appendicitis were discovered and a laparoscopic cholecystectomy and appendectomy were performed.
Acute acalculous cholecystitis is a rare clinical entity in young, healthy patients and this report describes the unusual association of acute acalculous cholecystitis and appendicitis. A single stage combined laparoscopic appendectomy and cholecystectomy is an effective treatment modality.

Acute acalculous cholecystitis (AAC) is rare clinical entity traditionally associated with elderly patients with extensive co-morbidities or critically ill patients, such as those with burns or who have sustained trauma. We present a case of an otherwise healthy 23-year-old man who presented with acute right sided abdominal pain and had ultrasonographic evidence of both AAC and acute appendicitis.
A 23-year-old unemployed Caucasian man presented to our Emergency Department with a twelve-hour history of severe right upper and lower quadrant pain. This pain originated in his epigastrium and was associated with nausea, multiple episodes of non-bilious vomiting and anorexia. His background history was unremarkable. He was on no regular medications, did not smoke and was a social drinker. On physical examination, he had a normal pulse and blood pressure but was pyrexic (38.5°C). An abdominal examination revealed tenderness in his right upper quadrant and right iliac fossa, guarding and rebound tenderness. Rovsing, obturator and psoas signs were negative. Laboratory investigations revealed an elevated white cell count of 14.3 × 109/L, and slightly deranged liver function tests, namely a total bilirubin of 54 μmol/L and aspartate aminotransferase of 39 U/L with normal renal function and electrolytes. A dipstick of his urine showed 1+ bilirubin, 1+ blood and 4+ ketones. His Alvarado score was 10, consistent with appendicitis .
AAC is a well-recognized but poorly understood clinical entity. Traditionally, it occurs in elderly patients with chronic debilitating disease or patients with critical illness, typically trauma or major burn injury. Whilst early case series associated AAC exclusively with critical illness , more recent reports demonstrate increasing de novo presentation of AAC in the absence of acute illness  and even in young, otherwise healthy patients without any predisposing factors . The age of onset of AAC has been reported to be most commonly in the sixth decade . The commonest postulated etiologies of AAC are bile stasis resulting in a change in bile composition, sepsis and ischemia . In critically ill patients, AAC results from gallbladder ischemia, which may be secondary to shock due to hypovolemia or sepsis.
It has previously been noted that a hyperbilirubinemia occurs in acute appendicitis . It has been proposed that appendicitis associated hyperbilirubinemia is due to bacterial translocation into the portal venous system, leading to altered bilirubin excretion. This, in combination with sepsis, may have precipitated AAC in our patient.
AAC is a rare clinical entity in young, healthy patients and to the best of our knowledge, this represents the first report of AAC associated with acute appendicitis. A single stage combined laparoscopic appendectomy and cholecystectomy was an effective treatment modality in this case, although the timing of surgery for acute cholecystitis remains controversial, with some surgeons opting for interval cholecystectomy which carries a lesser risk of conversion to an open procedure or damage to the common bile duct, whereas other surgeons prefer early cholecystectomy to avoid failure of conservative management and to prevent disease recurrence. Surgical management of AAC in the end depends on the severity of the disease, physical status of the patient and the laparoscopic skill of the surgeon.
