Laparoscopic Liver Resection with a SAND Balloon Catheter for a Large Mucinous Cystic Neoplasm of the Liver

This is the authors' abstract. We don't add key points for this paper.

A 48-year-old woman was referred to our department for managing the regrowth of a cystic lesion of the liver. MRI revealed an 11-cm multilocular cystic lesion occupying the left lobe. Given the lack of obvious malignant findings such as intracystic nodules, we decided to perform laparoscopic liver resection (LLR). During the surgery, retracting the large hepatic cystic lesion proved difficult. We therefore aspirated the cystic contents using a SAND balloon catheter, after which the cyst wall could be managed. Ultimately, LLR could be performed fully after sequentially dissecting the Glissonean vessels toward the cystic wall. Given the presence of ovarian-like stroma below the cystic epithelium, the patient was diagnosed with mucinous cystadenoma of the liver with low-grade dysplasia. For the patient with a large mucinous cystic neoplasm of the liver, a SAND balloon catheter may prevent the leakage of cystic contents and is considered an effective device for facilitating LLR.
