Blood vessels may be clamped or cauterized to prevent bleeding, and retractors may be used to expose the site or keep the incision open. The approach to the surgical site may involve several layers of incision and dissection, as in abdominal surgery, where the incision must traverse skin, subcutaneous tissue, three layers of muscle and then the peritoneum. In certain cases, bone may be cut to further access the interior of the body; for example, cutting the skull for brain surgery or cutting the sternum for thoracic (chest) surgery to open up the rib cage. Whilst in surgery aseptic technique is used to prevent infection or further spreading of the disease. The surgeons and assistants hands, wrists and forearms are washed thoroughly for at least 4 minutes to prevent germs getting into the operative field, then sterile gloves are placed onto their hands. An antiseptic solution is applied to the area of the persons body that will be operated on. Sterile drapes are placed around the operative site. Surgical masks are worn by the surgical team to avoid germs on droplets of liquid from their mouths and noses from contaminating the operative site. Work to correct the problem in body then proceeds. This work may involve:

excision – cutting out an organ, tumor, or other tissue. resection – partial removal of an organ or other bodily structure. reconnection of organs, tissues, etc., particularly if severed. Resection of organs such as intestines involves reconnection. Internal suturing or stapling may be used.
Also, drugs that are of poor quality or less in quantity, especially in developing countries, contribute to MDR TB. Identifying and diagnosing patients with HIV/AIDS as soon as possible. They lack the immunity to fight the TB infection and are at great risk of developing drug resistance. Identifying contacts who could have contracted TB: family members, people in close contact, etc. Research: Much research and funding is needed in the diagnosis, prevention and treatment of TB and MDR TB. "Opponents of a universal tuberculosis treatment, reasoning from misguided notions of cost-effectiveness, fail to acknowledge that MDRTB is not a disease of poor people in distant places. The disease is infectious and airborne. Treating only one group of patients looks inexpensive in the short run, but will prove disastrous for all in the long run. "— Paul Farmer

DOTS-Plus
Community-based treatment programs such as DOTS-Plus, a MDR-TB-specialized treatment using the popular Directly Observed Therapy – Short Course (DOTS) initiative, have shown considerable success in the world. In these locales, these programs have proven to be a good option for proper treatment of MDR-TB in poor, rural areas. A successful example has been in Lima, Peru, where the program has seen cure rates of over 80%.However, TB clinicians have expressed concern in the DOTS program administered in the Republic of Georgia because it is anchored in a passive case finding. This means that the system depends on patients coming to health care providers, without conducting compulsory screenings.
