Laparoscopic management of giant splenic true cyst with partial splenectomy: A case report

Non-parasitic splenic cysts are relatively rare, and the optimal surgical treatment for them remains controversial. Laparoscopic unroofing is a relatively safe and easy technique, but a significant number of recurrences has been reported. Thus, complete cystectomy with partial splenectomy is recommended by several surgeons. However, patients sometimes suffer from intra-operative bleeding. Here, we report a patient with a giant non-parasitic splenic cyst who underwent subtotal cystectomy with partial splenectomy. After the dissection of the vessels circulating the upper pole at the splenic hilum, the resection line of the splenic parenchyma was on the ischemic side of the cyanotic demarcation line. A vessel sealing system and laparo-scopic coagulation shears were used for the resection. We intentionally left about 10% of the cyst wall to avoid bleeding from the non-ischemic splenic parenchyma and remaining vessels. No recurrence has been detected after 6 months of observation. We believe this method could be a useful alternative procedure for the treatment of non-parasitic splenic cysts and preservation of the splenic parenchyma.
