Aspiration Prevention Surgery under Local Anesthesia for Palliative Care in Patients with Head and Neck Cancer: A Report of Two Cases.

Aspiration prevention (AP) surgery may improve the quality of life (QOL) of patients with severe dysphagia. However, not all patients can endure this type of surgery under general anesthesia because of their poor status. Herein, we describe the cases of 2 patients with head and neck cancer (HNC) who underwent AP surgery for palliative care. Although both patients had tracheostomy due to severe dysphagia and respiratory impairment and frequently needed suction, they were successfully managed with AP surgery under local anesthesia. A tracheostoma was reshaped to be sufficiently large for an airway to be secured without a cannula. Their respiratory failure gradually improved, and suction frequency markedly decreased after surgery; thus, they could receive medical treatment at home. When patients with HNC under palliative care have a tracheal cannula and cannot vocalize, AP surgery under local anesthesia is an option to improve their QOL.

Cholangitis complicated by infection of a simple hepatic cyst.

An 87-year-old man was admitted to our hospital due to fever and elevated liver enzymes. Computed tomography (CT) scan revealed bile duct stones with a dilated biliary system, which confirmed the diagnosis of cholangitis. A 12-cm simple hepatic cyst was also seen in the right liver, which had been detected on CT scan 5 years before, and did not change in size. Fever did not subside even after endoscopic biliary drainage and a repeated CT scan showed an enlarged cyst up to 14 cm, suggesting cyst infection. An enlarged hepatic cyst collapsed after percutaneous transhepatic drainage, along with resolution of fever. Simple hepatic cysts are common and most of them are asymptomatic. Infection of simple hepatic cysts is a rare condition and the major entry route is considered as the biliary tract as communication between the biliary tract and cysts is reportedly observed in those cases. However, in our case, no communication was seen on cholangiogram or cystogram on fluoroscopy and bilirubin level of the cyst aspirate was low. Given the fact that patients with cholangitis are rarely complicated by hepatic cyst infection, other routes of bacterial entry to simple hepatic cysts should also be considered.
