Abscess is the accumulation of pus in the tissues, organs or body cavities with an intact wall in the acute inflammation of deep tissues.

The treatment includes antibiotics for systemic or local use, local hot application, physical therapy, incision and drainage through operation, and the drain after operation is often vaseline yarn strips etc [21]. 

Zheng GH [22] treated 18 cases of abscess of iliac fossa through drainage with the use of MEBO oil yarn strips, and all the patients were healed in 7-10 days. The author came to a conclusion: drainage therapy with MEBO yarn strips was safe with few pains, short treatment course, low expense and high cure rate. 

Zhao BS etc. [23] treated 78 cases of perianal abscess with MEBO yarn strip drainage, and more than 90% of the patients were healed after 2-5 times of dressing change and drainage. He thought this method had following advantages: 

1. Analgesia;
2. Anti-infection;
3. Accelerating wound healing; 
4. Shortening the course of disease, 
5. and reducing workload. 

Ge XF etc. [24] treated 28 cases of perianal abscess with MEBO yarn strip drainage, 78% of the patients were healed after 3-4 times of dressing change and drainage. 

Kong QC etc. [25] treated 31 patients after hemorrhoids exsection with MEBO yarn strip pressing wound, and all the patients were healed. Compared with Yuhong ointment, a Chinese traditional medicine, the average healing time was reduced by 7 days. 

Zhang CY etc. [26] treated 56 cases of Bartholin's abscess with MEBO yarn strip tamping and drainage, the dressing was changed every other day and more than 90% of the patients were healed after 2-3 times of dressing.
