Abscess of intra-abdominal organs, if left untreated, can lead to sepsis or septic shock. Drainage of abdominal abscess under the guidance of enhanced X-ray is an effective treatment method for patients.

An abscess is an inflammatory pocket of tissue that is filled with pus. Abscesses can appear anywhere on the body. Abdominal abscess (intraperitoneal abscess) is a collection of pus or infected material in the abdomen. Abdominal abscess can be distributed in the middle abdomen, the back part of the abdomen or around the organs in the abdomen such as liver, pancreas, kidney,...
Abdominal abscess is usually caused by invading bacteria. enter the abdomen as a result of trauma, intestinal rupture, or following abdominal and gastric surgery. When having an abdominal abscess, patients often have symptoms such as: Feeling tired, abdominal pain, fever, nausea and vomiting, loss of appetite.

The symptoms of abdominal abscess are not specific, easy to confuse with symptoms of some other diseases. For an accurate diagnosis, the doctor needs methods such as blood tests, X-rays of the abdomen, abdominal ultrasound, computed tomography (CT scan), magnetic resonance imaging (MRI) or sample analysis. abscess translation.
To treat abscesses of intra-abdominal viscera, drainage is the first choice to drain pus from the abscess. In this procedure, the doctor will use X-ray, computerized tomography, ultrasound or digital background eraser to inject a needle through the skin, go directly into the abscess, and then use a pump to drain the fluid. . After draining the abscess, the doctor will send a sample of the fluid to a laboratory for analysis and an indication for appropriate antibiotic use.
In addition, some other cases require surgery to: Clean the abscess, if the abscess is difficult to reach with a needle aspiration or an intra-abdominal organ has ruptured. During surgery, the doctor will put the patient under general anesthesia, then make an incision in the abdomen to locate the abscess. Then, the doctor cleans the abscess, attaches a drainage tube to drain the pus out. The drain is left in place until the abscess heals.

Cases of abscesses in different organs in the body such as liver, kidney, spleen, pancreas, perirenal, intra-abdominal, retroperitoneal or intramuscular abscess.

Patients with coagulopathy, prothrombin rate less than 60%, platelet count less than 50 G/l; Patients with severe hepatic, renal, respiratory and circulatory failure.

Performers: Specialist doctors, assistant doctors, radiology technicians, anesthesiologists, nurses; Technical facilities: Television X-ray machine; ultrasound machine with flat and curved transducers; film, film printers and image storage systems; lead vest, apron, X-ray shielding, antibacterial plastic bag covering the ultrasound probe; Medicines: Local anesthetics or general anesthetics (if indicated), water-soluble iodine contrast agents, skin and mucosal antiseptic solutions; Common medical supplies: Syringe; physiological saline or distilled water; gloves, gowns, caps and surgical masks; cotton, gauze, surgical tape; sterile interventional kit (knife, scissors, tongs, metal bowl, bean tray, tool tray); medicine boxes and emergency equipment for iodine contrast drugs; Special medical supplies: Kim Chiba; the conductor corresponds to the Chiba needle; drug pump connection; pigtail drainage catheter; sutures to fix the catheter; Patient: The procedure is explained; fast and drink before 6 hours, can drink less than 50ml of water; In the intervention room, the patient lies on his back, prone or on his side depending on the drainage position, at the same time installing a monitor (breath rate, blood pressure, pulse, electrocardiogram, SpO2), disinfecting the skin and then covered with a sterile towel. hollow. Can give the patient sedation if too excited, do not lie still; Test sheet: Includes medical records, order of procedure, X-ray film, magnetic resonance, computed tomography if any.

Pre-intervention assessment: Ultrasound and/or computed tomography to evaluate abscess; determine the location, limit and nature of the abscess. Then mark the expected site of access to the abscess; Exposing the way in: Wide antiseptic at the needle puncture site, local anesthesia, small incisions on the skin with a surgical knife; Accessing the abscess: Insert a guide needle through the skin incision into the abscess. Next, inject contrast material into the abscess cavity to confirm that the needle is already inside the abscess. Then, drain fluid from the abscess to culture, isolate microorganisms, make an antibiotic chart, and then insert the guide wire into the abscess cavity through the guide needle; Insertion of a drainage tube: Insert a catheter into the abscess cavity by following the guide wire to widen the inlet, the size increases gradually depending on the diameter of the catheter intended to be placed. Next, insert the pigtail drain into the abscess by following the lead, fix the catheter with a surgical suture needle. Finally, use sterile physiological saline to flush the abscess until the fluid is clear.

The catheter is firmly fixed to the abdominal wall - thorax, the distal end of the catheter is in the abscess; Assess puncture site and catheter drainage; Monitor the patient's pulse, blood pressure and temperature.

Heavy bleeding: Treat with blood transfusion or surgery; Shock due to pain or drug shock: The procedure should be discontinued and anti-shock treatment according to the standard protocol; Abscess drainage into the abdomen, gastrointestinal fistula: Option to continue drainage and surgery on a case-by-case basis; Infection: Should be treated with antibiotics or surgery on a case-by-case basis. Drainage of intra-abdominal abscesses under enhanced radiographs is an effective treatment for this condition, reducing the risk of serious complications. Patients assigned this technique need to coordinate with all instructions of the doctor to ensure effective treatment.
