Thoracoscopic plication of the membranous portion of crescent-type tracheobronchomalacia in an elderly patient: a case report.

ABSTRACT: BACKGROUND:It is presumed that tracheobronchomalacia in adults is caused by airway pressure-induced injury due to chronic cough related to pulmonary emphysema or chronic bronchitis. Commonly, a posterolateral approach using stabilizing materials is the surgical technique of choice for treating tracheobronchomalacia. We report a case in which thoracoscopic plication of the membranous portion was performed instead of airway stent placement for tracheobronchomalacia in an elderly individual. CASE PRESENTATION:An 87-year-old man who had been treated for bronchial asthma, pulmonary emphysema, and tracheobronchomalacia was admitted to our hospital with acute exacerbation of dyspnea. The patient underwent tracheal intubation, which was followed by tracheostomy 16?days later. Insertion of the tip of the adjustable-length tracheostomy tube to the end of the stenotic lesion enabled him to breathe spontaneously. However, conservative management failed due to recurrent pneumonia caused by the tracheobronchomalacia. Crescent-type tracheobronchomalacia (Johnson's classification grade III) was diagnosed, and the main narrowed area of the trachea was assumed to be approximately 3-10?cm from the tracheal bifurcation. A thoracoscopic approach was selected because a posterolateral approach was considered too invasive considering the patient's age and general condition. We placed eight stitches on the tracheal membranous portion and four stitches on the membranous portion of the right main bronchus, using the horizontal mattress suture technique. The use of foreign materials was avoided because meropenem-resistant Pseudomonas aeruginosa was cultured in a tracheal specimen. Immediately after the operation, the expiratory airway stenosis improved, and subsequently, spontaneous ventilation was possible using a normal type of tracheostomy tube instead of an adjustable-length tracheostomy tube. CONCLUSIONS:Tracheobronchomalacia is not a rare condition in patients with chronic obstructive pulmonary disease. The thoracoscopic approach is less invasive than the posterolateral approach and is suitable in cases that are otherwise refractory to medical treatment. We believe that thoracoscopy may be a useful treatment option in cases where conservative treatment is not appropriate.

Project description:Although previous studies have reported the use of total thoracoscopic hepatectomy (TH) for malignant liver tumors, it is technically impossible to perform intraoperative ultrasonography (IUSO) to exclude intrahepatic metastasis for the whole liver via a thoracic approach. Therefore, total TH may be inappropriate for these patients. We here report the first case of modified TH for a malignant liver tumor in China.The patient was a 26-year-old man with a 10-year HBV infection. Preoperative CT showed a 1.2 cm × 0.9 cm mass located in segment VIII. His alpha-fetal protein level was 444 ng/mL. Child-Pugh was Grade (A, 6), whereas an ICG-15 test yielded 2.7%. HCC was diagnosed preoperatively. The indications for TH were difficult tumor location, HCC, and a young patient with good resilience.The modified TH included 2 steps: (1) the patient was placed in a supine position. IUSO was used to locate the tumor in segment VIII and determine that intrahepatic metastasis had not occurred. The hepatoduodenal ligament was hanged over using a Pringle maneuver; (2) patient was then placed in the left-lateral position with single-lung ventilation. Three trocars were placed into the right thoracic cavity. The intra-thoracic space was observed using a regular 10-mm rigid scope. The diaphragm was transected and retracted. IUSO was used again to confirm the tumor location. Under the Pringle maneuver (once every 10 min), the superficial portion of the liver was transected by ultrasonic shears, whereas the deeper tissue was transected by LigaSure. Bipolar was used for hemostasis. The specimen was put into a retrieval bag and removed from the abdominal trocar. The diaphragm was repaired by running suturing. The operation time was 260 minutes and estimated blood loss was 30 mL. The patient was discharged on postoperative day 5 with normal liver function. No complications arose.Total TH may be inappropriate for malignant liver tumors due to the limitation of IUSO for the whole liver. The 2-step modified TH is technically feasible and suitable for malignant liver tumors located in segments VII or VIII.Video abstract: http://links.lww.com/MD/B6.
