Abstract:
Objective:To evaluate the safety and efficacy of ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique for the treatment of complex encapsulated lesions.Methods:A total of 48 patients(48 lesions) with complex encapsulated lesions who underwent ultrasound-guided percutaneous negative pressure suction and minimally invasive rotatory excision technique at Xi′an Chest Hospital from January to October 2023 were retrospectively enrolled, including 39 cases of encapsulated abscess, 7 cases of encapsulated effusion, and 2 cases of encapsulated haematoma; the distribution of the bacterial flora of the abscesses were as follows: 24 cases of tuberculous abscess, 14 cases of bacterial abscess, 1 case of bacterial combined bacterial-fungal abscess, and 7 cases of encapsulated effusion were tuberculous pleurisy, and the clinical data were analysed retrospectively. The maximum upper and lower diameters, right and left diameters, and anterior and posterior diameters of the lesions were measured by ultrasound before and after the operation. The patients′ various biochemical indicators (C-reactive protein, white blood cell count, neutrophil count, erythrocyte sedimentation rate) were detected. The intraoperative and postoperative complications, postoperative outcomes, and postoperative clinical symptoms were recorded.Results:Of the 48 patients, 39 were cured and discharged after negative pressure suction and rotatory excision technique, and 9 patients were cured and discharged after surgical incision and drainage of the lesions. The overall effective rate of negative pressure suction and rotatory excision treatment reached 81.25%, and the average number of days of tube placement was (11.81±7.22) days, and the average number of days of follow-up was (35.77±19.39) days. Compared with preoperative values, the upper and lower diameters, the left and right diameters, and the anterior and posterior diameters of the lesions were all reduced after operation [5.80 (4.95, 7.95)cm vs 8.00 (6.00, 11.82)cm, 4.00 (3.25, 5.00)cm vs 5.85 (4.52, 7.65)cm, 1.80 (1.00, 2.90)cm vs 3.40 (2.50, 6.15)cm, all P<0.01]; and postoperative C-reactive protein, white blood cell count and neutrophil count all decreased (all P<0.05). Before operation there were 31 cases of local swelling, 16 cases of pain, 12 cases of activity limitation, 12 cases of fever, 7 cases of chest tightness, and 6 cases of shortness of breath, and during postoperative follow-up, there were 4 cases of local swelling, 5 cases of pain, and 4 cases of activity limitation. The symptoms of fever, chest tightness, and shortness of breath all disappeared, and there was a statistically significant difference between preoperation and postoperation (all P<0.05). There were no adverse events or complications associated with the intraoperative and postoperative follow-up of negative pressure suction and rotatory excision treatment. Conclusions:Ultrasound-guided percutaneous negative pressure suction and invasive rotatory excision technique for the treatment of complex encapsulated lesions can significantly reduce lesion size, reduce inflammatory response and improve patient symptoms, which is a safe, effective and minimally invasive technique.
