[Application of computed tomography and abdominal pressure measurement in the treatment of giant incisional hernias].

Giant abdominal wall defects represent a major challenge for surgeons. CT scan can determine the ratio between the volume of the hernia sac and the abdominal cavity, determining the extent of the disproportion, which is related to the postoperative abdominal pressure value. Confirmation of the significance of CT examination in postoperative giant abdominal wall defects, effectiveness analysis of the reconstruction method by abdominal pressure measurement. A prospective study is conducted on patients with giant incisional hernias, with preoperatively performed abdominal CT scan. Tension-free abdominal wall reconstruction is realized with retromuscular Prolene mesh and hernial sac. Abdominal pressure is measured during and after surgery. Patients' follow-up is performed through phone after 2-4-6 months. We present our results through three cases. First case: 48-year-old woman presented a giant recurrent incisional hernia and multiple comorbidities. Maximum defect diameter was: 155 mm, hernia volume: 1536.63 cm, BMI = 43.6. The patient was discharged after seven days. Second case: 51-year-old male patient presented with multilocular giant incisional hernia, BMI = 26,85. Maximum diameter of the two wall defects were 123 mm and 105 mm, their total volume: 406.41cm. The patient was discharged after five days. Third case: A 67-year-old male patient presented with giant incisional hernia. The abdominal defect size was 100/100 mm (LL/CC), volume: 258.10 cm, BMI = 23.7. The patient was discharged after four days. The proper surgical technique can be established based on the preoperative CT scan. Abdominal wall reconstruction with retromuscular Prolene mesh and hernial sac provides a cheap, reliable, tension-free technique. The technique's short-term efficacy can be determined by abdominal pressure measuring through the bladder. Orv Hetil. 2020; 161(9): 347-353.
