Abstract:
Objective:To explore the feasibility of using ligation clip-assisted modified " expansion and co-llapse method" to determine the intersegment plane in thoracoscopic resection of the external posterior basal segment (S 9+ 10) in children with congenital pulmonary airway malformation (CPAM). Methods:Retrospective study.The clinical data of 12 CPAM children who underwent thoracoscopic S 9+ 10 resection in Children′s Hospital Affiliated to Shandong University from July 2019 to May 2021 were collected and analyzed.There were 7 males and 5 females.The age at operation ranged from 3.50 to 11.50 months.The body weight of patients ranged from 6.5 to 11.5 kg.In all the patients, the ligation clip-assisted modified " expansion and collapse method" was applied during the operation to determine the intersegment plane (S 9+ 10 was in the expansion state and the remaining lungs were in the collapse state) before thoracoscopic S 9+ 10 resection.After S 9+ 10 resection, the surgical treatment and postoperative recovery were summarized and analyzed. Results:All the operations were completed under thoracoscopy, and there was no conversion to thoracotomy.In 11 patients, the intersegment plane was accurately determined by the ligation clips-assisted improved " expansion and collapse method" , and the S 9+ 10 segment was successfully resected.Of these 11 cases, 8 cases had right S 9+ 10 resection and 3 cases had left S 9+ 10 resection.In the process of using the ligation clip-assisted improved " expansion and collapse method" to determine the intersegment plane, the operator needed to clamp the ligation clip after the anesthesiologist expanded the lung completely.Because the operation was not stable enough, the ligation clip fell off and did not clamp S 9+ 10, resulting in operation failure.The operation was changed to the traditional " expansion and collapse method" . Besides, the basal segment bronchus was cut off by mistake, so the right basal segment had to be resected.The operation time ranged from 85 to 205 min, with a median of 149 min.Intraoperative bleeding ranged from 5 to 15 mL, with a median of 10 mL.The indwelling time of drainage tubes ranged from 2 to 4 days, with a median of 3 days.The postoperative hospital stay ranged from 5 to 8 days, with a median of 6 days.Postoperative pathological examination results suggested 4 cases of type 1, 6 cases of type 2 and 2 cases of type 3.There were 2 cases of simple subcutaneous emphysema without postoperative complications such as bleeding, bronchopleural fistula and atelectasis.The follow-up time ranged from 6 to 28 months, with a median of 15 months.The chest CT of all children showed no residual lesions and no residual cavities in the involved hemithorax. Conclusions:Ligation clip-assisted improved " expansion and collapse method" for determining the intersegment plane is suitable for CPAM children with a narrow thoracic space, and the operation is simple and effective.It is relatively safe and feasible to use this method in S 9+ 10 resection.
