Anterior abdominal wall abscess secondary to subcutaneous gallstones

Cholecystocutaneous fistula incidence, Etiology, Clinical Manifestations, Diagnosis and treatment. A literature review

Cholecystocutaneous Fistula (CCF) is a type of external biliary fistula, which connects the gallbladder with the skin. Thilesus first described this phenomenon in 1670. There is usually a history of calculi in the gallbladder or neglected gallbladder disease. The incidence of CCF is rare, most patients are elderly females with the mean age of 72.8 years old. They usually present with chronic calculus cholecystitis or a history of a previous surgical intervention. US, CT, MRI, MRCP and (CT or X-ray) fistulogram are used to confirm the diagnosis. CT was more significant than US in identifying the track of the fistula and the fluid that runs throw it. CCF patients presented with systemic symptoms (fever, nausea and vomiting) or local symptoms. RUQ region is the most common site of external opening. Open cholecystectomy with excision of the fistulous tract is considered an acceptable option for treatment and it is curative in most cases. However, laparoscopic approach can be another option with experience surgeons.

Case Report: Spontaneous cholecystocutaneous fistula, a rare cholethiasis complication

One of the most unusual complications in cholethiasis is spontaneous cholecystocutaneous fistula, which has only been reported a few times in the literature.  We report the case of a 76 year old man who presented with a right hypochondrium subcutaneous abscess, with pain evoked through palpation.  No comorbidity in the patient’s medical history were noted.   Confirmation of cholecystocutaneous fistula was made using the proper diagnostic process, which is computed tomography with contrast media, followed by hepatobiliary MRI. This confirmed the presence of a fistulous pathway between the gallbladder and the skin.  The patient underwent cholecystectomy surgery and open laparotomy with en block aponeurotic muscle, skin and fistula orifice excision.

Cholecystocutaneous abscess: diagnostic difficulty in a groin lump

An older patient presented with a 4-week history of tender lump in the right groin. Appearances were consistent with strangulated inguinal hernia and theatre was arranged. At operation, the lump was found to be an abscess communicating with the abdominal cavity. Alternative diagnosis requiring further operative management was considered but consent was deemed inadequate to proceed. Operation was abandoned and CT examination arranged. CT unexpectedly identified a cholecystocutaneous abscess discharging through the right inguinal region. The patient made good clinical recovery with ongoing drainage of the abscess and did not require any further operative treatment.
