Transrectal pelvic abscess incision and drainage

Use a scientific method to drain the abscess through rectal pelvic abscess incision and drainage. Note: 1. Before cutting the abscess, you must first test the puncture, and the extracted liquid must be different from the small intestinal fluid. The pus is generally uniform, yellow, with odor, and pus cells are seen on microscopic examination; the small intestinal fluid is generally uneven, with lumps, slightly odorous, and different colors, with some frozen samples, and no pus cells or microscopic examination Ascaris eggs are visible. 2. There is an intestinal tube between the abscess and the anterior wall of the rectum. When the test puncture and extraction are intestinal contents, this method cannot be used for drainage. Intra-abdominal abscess incision and drainage should be used instead. 3. When transrectal incision, the incision direction should be as far as possible forward, not completely forward. Avoid making transverse incisions in the rectal wall. The drainage location should be low, and the incision should be large enough to allow smooth drainage. 4. When entering the pus cavity, be gentle, so as not to damage the surrounding organs. The insertion direction of the vascular forceps should be basically parallel to the rectal wall, and the penetration should not be too deep, so as not to rupture the pus cavity wall into the abdomen and cause the infection to spread. 5. The pus is routinely sent to bacterial culture and drug sensitivity tests. 6. Male patients undergo pelvic abscess incision through the rectum. After surgical expansion of drainage, 200 ~ 300ml of normal saline should be injected into the bladder from the catheter. If the infusion solution comes out of the drainage port, it indicates that there is bladder injury, and the bladder repair should be performed after the drainage is placed. Reasons All instruments and dressings should be replaced. Surgical access to the bladder extraperitoneally on the pubic bone. Generally, the injury can be found in the triangle of the bladder and the ureter, and the injured muscle layer and mucous membrane are sutured intermittently with the intestinal line. A mushroom or umbrella-shaped urethral catheter is placed in the bladder, and the bladder and abdominal wall are closed.
