Minor surgery is any invasive operative procedure in which only skin or mucus membranes  and connective tissue is resected e.g. vascular cutdown for catheter placement, implanting pumps in subcutaneous tissue. Procedures in which the surgical field cannot be effectively disinfected, e.g. tooth extractions and gingival grafts, will generally be considered minor. This category also includes biopsy, an invasive operative procedure for procurement of tissue samples or body fluids using a needle or trocar.
Minor surgical procedures may be done in our laboratory using appropriate aseptic technique, including a clean work area, preparation and disinfection of the surgical site including clipping of the hair and surgical scrub of the skin, draping of the surgical site with sterile drapes, mask by the surgeon and any assistants working in the surgical field.
