Digital Mucous Cyst Clinical Trial
Official title:
A New Surgical Treatment Technique "Aspiration and Percutaneous Capsulotomy" for Digital Mucous Cyst
Digital mucous cysts (DMCs) are a benign rubbery cystic lesion which usually involve the dorsal or lateral side of DIP joint (digital interphalangeal joint) or proximal nail fold. The most successful treatment way is surgical management. However, which may cost time, require expertise, may cause infection, prolong wound healing and sometimes may lead to the joint movement limitation. The investigator bring this new technique: percutaneous capsulotomy for digital mucous cysts, which is easy and quick, last but not least, low recurrence rate.
Participant
Between 2016 and 2017, 50 participants with DMCs in Taipei veteran general hospital were
included in this study. According to the clinical assessment at OPD(out participants
department), DMC was diagnosed. Serial related serial clinical features of DMCs were
investigated including participant's age, location, size of cysts, symptoms, duration, nail
bed condition, underlying disease(ex. rheumatoid disease, Diabetes) and previous treatment.
After explaining to participants about the treatment choice (surgical excision, aspiration of
cystic contents, and our needle assisted percutaneous capsulotomy for mucous cyst) and
participants agreed with accepting needle assisted percutaneous capsulotomy, they were
selected for accepting our needle assisted percutaneous capsulotomy for mucous cyst.
Surgical capsulotomy procedure.
The surgical procedure for DMCs was using a 18G needle performing aspiration first and then
cutting the stalk tract by the needle tip for capsulotomy. All procedure were done with local
anesthesia. After operation, the investigator asking participants using dressing to pressure
the wound about 10 minutes to stop bleeding. Later on, the wound was covering with
antimicrobial ointment (neomycin) and simple dressing. Educating participants from water for
24 hrs.
Clinical assessments
The investigator evaluating participant's prognosis by VAS, the improvement of fingernail
deformity, the participants' subjective satisfaction and the recurrences was evaluating
during follow-ups. This clinical study's approval was obtained from Association of IRB,
Taipei veteran general hospital.
