Abstracted from: Wang Cheng, Jin Feng, et al: Surgical treatment of chest wall tuberculosis: a clinical analysis of 179 cases. (Published in: China Comprehensive Clinical 2009, No.2) The surgical incision was made in stages. Shandong Provincial Chest Hospital Thoracic Surgery Department Wang Cheng skin with sinus tracts, the sinus tract mouth skin line shuttle excision, suction pus, scraping the sinus tract and the pus cavity with which the diseased tissue, dry gauze filling and electrocoagulation hemostasis, explore the direction of the sinus tract, and then according to the direction of the sinus tract to determine the direction of the extension of the incision and the length of the incision. If the sinus tract is long and the main lesion is far away from the sinus tract, then an incision is made at the blind end of the sinus tract along the ribs under the guidance of a probe in the sinus tract in order to reveal and remove the main lesion. If there is no sinus tract in the skin, the incision is made in the middle of the abscess in the chest wall along the direction of the ribs, and the incision is appropriately cut about 4M, and the corresponding curved extension is made according to the probing situation; if the abscess has broken through the muscle membrane and has already reached the subcutaneous tissues, the pus will be suctioned, and then it will be separated along the sinus tract in the direction of the muscle fibers to reach the abscess; if the abscess has not broken through the muscle membrane, it will be separated or cut through the muscle to reach the abscess. Aspirate the pus, quickly scrape the abscess wall, use dry gauze to stop bleeding, and after withdrawing the gauze, electrocoagulate the remaining bleeding point to stop bleeding. Adjust the light, in the bloodless trauma cavity under direct vision to explore the sinus tract and its direction and to find out the status of the rib in the abscess cavity, completely remove the tuberculous lesion tissue in the sinus tract and track the open to the blind end, there are ribs with periosteal defects, bone destruction and the deep surface of ribs with sinus tracts or dumbbell-type abscesses, will be the corresponding rib segments excision. If the sinus tract is submerged under several rib beds, the direction of the sinus tract should be explored first, and the covered rib segments should be removed, then the outer wall of the sinus tract should be lifted up with a spatula or curved forceps in the sinus tract, avoiding the intercostal blood vessels and nerves, and the sinus tract wall should be cut in a direction parallel to the intercostal blood vessels and intercostal nerves, and the sinus tract wall should be cut open and shortened to the blind end starting from the rib beds adjacent to the mouth of the sinus tract and the lesion tissues should be removed one by one. If the residual cavity is large, a muscle flap with good blood flow is used to fill the cavity adequately, and the bottom of the cavity is fixed with absorbable sutures, and the periphery is reinforced with silk thread away from the lesion. If the trauma is large and the exudate is large, a porous silicone tube is placed to drain under negative pressure. The drainage tube is submerged in the healthy muscle tissue and drains out from the opposite direction of the gravity of the fluid when the patient is lying down or in the upright position. If it is difficult to transfer the muscle flap or if there are many skin defects that cannot be closed in one stage, the wound cavity is filled with iodine-vapor oil gauze after the lesion is cleared and the medication is changed one by one.
