Basic information】Female, 50 years old 【Disease type】 Polycystic liver 【Hospital】 Liaocheng People’s Hospital 【Time of consultation】March 2022 【Treatment plan】Surgery (laparoscopic left hemihepatectomy) + Intravenous injection (compound glycyrrhizic acid glycoside injection, cefoperazone sodium sulphadoxine sodium for injection, growth inhibitor for injection) 【Treatment cycle】Hospitalization for 7 days, and outpatient review half a month later 【Effects of treatment Patient’s dyspeptic symptoms disappeared, no recurrence on follow-up, good mental state, normal diet I. Initial interview 50-year-old Liu said she had dyspeptic symptoms for more than a year, thought it was a stomach disease, did not pay attention to it, and then the symptoms worsened, so she came to our hospital. When asked about her past medical history, she said that she had a liver cyst 7 years ago, which was not treated because it was small and asymptomatic at that time. When asked about her family history, she said that her mother had a polycystic liver. The patient was prescribed a CT abdomen, which revealed multiple cysts in the liver, mainly located in the left half of the liver, and was initially diagnosed with polycystic liver, which required timely surgical treatment. So the patient was prescribed the relevant preoperative examination, and explained that the patient needed surgical treatment, and the patient agreed. Second, the treatment process The patient improved the relevant preoperative examinations, and laparoscopic left hemihepatectomy was performed under general anesthesia at an elective stage. After the operation, compound glycyrrhizin injection was given to protect the liver, and at the same time, cefoperazone sodium sulbactam sodium for injection was given for anti-infection treatment, and growth inhibitor for injection was given intravenously to assist in relieving the condition. The patient was hospitalized for 5 days, then the drain was removed, and he was discharged after 7 days. He was instructed to eat less greasy food recently, and was rechecked in the outpatient clinic after half a month. Polycystic liver is a benign disease, and there are often no symptoms when the liver cysts are small in the early stage, but the cysts will press the liver and even the surrounding organs in the later stage, which will cause symptoms of the digestive system. The patient was discharged after 7 days of hospitalization, at which time the symptoms of indigestion disappeared, liver function and other indexes were not abnormal in the follow-up, there was no recurrence of the phenomenon, the mental state was good, the diet was normal, and the patient was relatively satisfied with the therapeutic effect. Note: We are glad that the patient’s condition has been effectively treated, but we still need to advise the patient to pay attention to keep the skin clean and hygienic at the incision before the incision is completely healed to avoid infection. At the same time, pay attention to the diet mainly to light, easy to digest, avoid eating spicy stimulating food, and prohibit drinking alcohol, so as not to aggravate the burden on the liver. V. Personal perception Polycystic liver is often overlooked because of the lack of specific symptoms in the early stage, but it should be emphasized because it may produce more serious complications. The patient in this article started with symptoms of dyspepsia, and it was only after examination that it became clear that he had polycystic liver. Therefore, polycystic liver should be considered in addition to gastrointestinal disorders when gastrointestinal symptoms occur. Polycystic liver is a hereditary disease, and one should be aware of one’s own checkups when there are such patients in the family.
