Giant hepatic hemangioma

Real-world data on the clinicopathological traits and outcomes of hospitalized liver hemangioma patients: a multicenter study

Background

There is currently a lack of consensus regarding the clinical features, diagnosis, treatment indications and options, and risk assessment of hepatic hemangioma patients.

Methods

This was a multicenter, real-world study that analyzed a large number of hepatic hemangioma cases in China and included patient data on epidemiology, diagnosis, treatment methods, and outcomes.

Results

A total of 5,143 patients hospitalized for hepatic hemangioma were included, of whom 34.42% were male and 65.58% were female. The age distribution was concentrated between 30 and 60 years old, accounting for 87.41% of the patients. Among the hepatic hemangioma patients, 60.8% had only one tumor, with the most common pathological type being cavernous hemangioma (96.07% of cases). The treatment motivations and indications included anxiety, obvious clinical symptoms, rapid tumor growth, unclear diagnoses and acute emergencies. Overall, 41.4% of the patients were treated for psychological reasons, while 30.59% were treated because they presented obvious (primarily nonspecific) clinical symptoms. Hepatic resection was the main therapeutic method and was based on various indications. There were a small number of patients with Kasabach-Merritt syndrome, according to its generally recognized definition.

Conclusions

Most patients in this study who were hospitalized for hepatic hemangioma did not meet the indications for requiring treatment. Surveillance is the recommended course of action for definitively diagnosed hepatic hemangioma, and a new classification system is needed to standardize the diagnosis of this condition.

Surgical indication and strategy for liver hemangioma in the caudate lobe: a multi-institutional retrospective analysis with 137 patients

Objective

To investigate the surgical indication and tactics for liver hemangioma in the caudate lobe

Methods

From January 1994 to July 2019, 137 patients, including 51 males and 86 females with the average age of 49.2 years old were diagnosed with liver hemangioma in caudate lobe and received treatment at five tertiary referral hospitals. Clinical features, correlations between tumor size and clinical manifestations, treatments, and prognosis were analyzed.

Results

Of the 137 patients identified, 40 (29.20%) patients were asymptomatic, whereas other 94 patients had clinical symptoms mainly presented as upper abdominal discomfort, epigastric distention, upper abdominal dull pain, nausea, and vomiting. Fifteen (93.75%), 18 (39.13%), and 7 (10.45%) patients presented no clinical symptoms among those tumor size was less than 3 cm (D ≤ 3 cm, n = 16), 3 cm < D ≤ 6 cm (n = 46), and 6 cm < D ≤ 9 cm (n = 67), respectively, while all 8 patients with tumor larger than 9 cm were symptomatic. Tumor diameter was obviously associated with the presence of clinical symptoms. In follow-up period, 7 patients in the conservative group (n = 39) received surgery because of tumor growth or symptom appearance. Totally 105 patients received operation including partial resection or isolated complete resection of caudate lobe and caudate lobe resection combined with liver segment resection, right liver resection, or left liver resection. All operations went smoothly, and no severe complications appeared.

Conclusion

Tumor diameter was obviously associated with the presence of clinical symptoms in patients with hemangioma in caudate lobe. Surgical therapy is not recommended for asymptomatic patients and available for patient who has symptoms. Effective surgical strategies should be put into use to reduce operative bleeding.
