OBJECTIVETo explore the clinical effect of electro-acupuncture (EA) in treating patients with lingual hemangioma (LHG).

METHODSEA therapy was applied on 36 patients by directly inserting the platinum needles into LHG through a trocar with plastic insulating cannula to protect the normal tissues and connecting the needles with the electro-chemical therapeutic apparatus of model ZAY-B. Then electricity was given until the tumor body got contracted and rigid. The result was assessed 6 months after EA was started.

RESULTSAll patients were treated effectively, namely, the effective rate was 100%, with the therapeutic effect reaching grade I in 29 patients (80.6%), grade II in 7 (19.4%), and all having the function of tongue recovered to normal.

CONCLUSIONEA shows special superiorities in treating LHG, proved to bring about less injury and quick recovery and being simple in operation. Especially when applied on huge LHG, it could not only remove the tumor, but also preserve the function of the tongue, so it is a brand-new approach that is likely to be accepted by patients.

OBJECTIVETo assess the feasibility and safety of radiofrequency ablation (RFA) in spleen to treat secondary splenomegaly and hypersplenism in dogs.

METHODSFourteen healthy mongrel dogs were randomly divided into two groups: group A (n = 4) and group B (n = 10) Both groups underwent ligation of the splenic vein and its collateral branches to induce congestive splenomegaly. At the end of the 3rd week, radiofrequency thermal ablation of the spleen was performed in the group B via laparotomy. After splenic RFA, the procedure-related complications were observed, CT scan was performed and the spleens were obtained according to schedule. The radiofrequency (RF) thermal lesions and its histo- pathological changes of the spleen were examined regularly.

RESULTSThere were no morbidity and mortality in the experimental dogs. CT findings revealed that splenomegaly could sustained over 2 months after ligation of the splenic vein. The segmental RF lesions included hyperintense zone of coagulative necrosis and more extensively peripheral hypo-intense infarcted zone. The latter was called as "bystander effect". The infarcted zone would be absorbed and subsequently disappeared between 4 and 6 weeks after RFA, and the size of the remnant spleen shrunk, but the lesion of coagulative necrosis hardly altered. The fundamental histopathological changes of splenic lesions caused by RF thermal energy included local coagulative necrosis and the peripheral thrombotic infarction zone. Subsequently, tissue absorption and fibrosis occurred in the zone of thrombotic infarction. Simultaneously occluded vessels, fibrin deposition, and disappearance of normal splenic sinuses resulted in the condensed structure of the viable remnant spleen, which were the pathological basis responsible for the shrunk spleen.

CONCLUSIONSIt is feasible and safe to perform RFA in the spleen to treat experimental splenomegaly and hypersplenism. The RFA technique could be safely performed clinically via laparotomy or laparoscopic procedure to strictly isolate the spleen from the surrounding organs.

OBJECTIVETo study the security and curative effect of radiofrequency ablation (RFA) for hypersplenism due to portal hypertension in the near future.

METHODS12 patients of the disease were treated with RFA. The blood count showed that WBC is (2.0 +/- 0.7) x 10(9)/L, PLT (25 +/- 10) x 10(9)/L, RBC (3.08 +/- 0.56) x 10(9)/L. In manners of systemic anaesthesia, through skin or in the operation or under the celioscopes the RFA needles are inserted the upper and middle parts of spleen in the instructing of US. Average time of RFA is (36.4 +/- 5.4) s.

RESULTSAfter the RFA, 1 case develop hematoma under the envelope of liver, and 1 case developed skin burn; 6 patients appeared middle or little fluid in the left thorax, 2 of them were drawn through puncture. The volume of spleen and damaged part of spleen from RFA were determined by enhanced CT in the days of 10 after RFA, the percentage of damaged part of spleen from RFA is 49.1% (23.3% - 88.9%). In the days of 14 after RFA, RBC is (5.5 +/- 0.9) x 10(9)/L, PLT is (124 +/- 21.36) x 10(9)/L; In the days of 33 after RFA, RBC is (5.4 +/- 1.1) x 10(9)/L, PLT is (205 +/- 34) x 10(9)/L. The levels of WBC and PLT in the blood after RFA are significantly higher than those of levels of WBC and PLT before RFA (P < 0.01).

CONCLUSIONSRadiofrequency ablation for Hypersplenism due to portal hypertension of hepatitis hepatocirrhosis is safety and credibility and has excellent curative effect in the near future.
