ABSTRACT
@#Objective To compare the clinical effect of single mediastinal drainage tube and both mediastinal drainage tube and closed thoracic drainage tube for the patients who received thoracoscopic radical resection of esophageal carcinoma. Methods We enrolled 96 esophageal carcinoma patients who received thoracoscopic radical resection from June 2016 to October 2018. Of them, 49 patients were indwelt with both mediastinal drainage tube and closed thoracic drainage tube (a chest & mediastinal drainage group, a CMD group) while the other 47 patients were indwelt with single mediastinal drainage tube (a single mediastinal drainage group, a SMD group). The total drainage volume, intubation time and incidence of postoperative complications (postoperative atelectasis, pulmonary infection, pleural effusion and anastomotic leakage) between the two groups were compared. The pain score and comfort score were also compared between the two groups. Results The total drainage volume and intubation time in the SMD group were not significantly different from those in the CMD group (1 321±421 mL vs. 1 204±545 mL, P=0.541; 6.1±3.7 d vs. 6.4 ±5.1 d, P=0.321). The incidence of postoperative complications (postoperative atelectasis, pulmonary infection, pleural effusion and anastomotic leakage) in the SMD group was not significantly different from that in the CMD group (10.6% vs. 6.1%, P=0.712; 4.3% vs. 10.2%, P=0.656; 6.4% vs. 12.2%, P=0.121; 2.1% vs. 4.1%, P=0.526). The numerical rating scale (NRS) pain scores on the first to the fifth day after surgery and during extubation in the SMD group were significantly lower than those in the CMD group (3.2±2.1 vs. 5.1±2.4, P=0.041; 2.8±0.6 vs. 4.8±1.4, P=0.015; 2.1±0.4 vs. 4.5±0.4, P=0.019; 1.7±0.7 vs. 4.0±0.8, P=0.004; 1.8±0.7 vs. 3.2±1.2, P=0.006; 1.4±0.2 vs. 2.5±3.4, P=0.012). The VAS comfort scores in the SMD group were significantly lower than those in the CMD group (3.6±1.7 vs. 6.6±3.7, P=0.018; 2.9±2.0 vs. 5.1±3.4, P=0.007; 2.1±1.4 vs. 5.5±2.4, P=0.004; 3.0±0.9 vs. 4.6±3.8, P=0.012; 1.8±1.1 vs. 4.2±2.7, P=0.003; 2.4±3.2 vs. 5.3±1.7, P=0.020). Conclusion The clinical effect of single mediastinal drainage tube in thoracoscopic resection of esophageal carcinoma is similar to that of both mediastinal drainage tube and closed thoracic drainage tube, but it can significantly improve the comfort of the patients.
ABSTRACT
@#Objective To analyze the outcome of fast track surgery after intercostal nerve block (INB) during thoracoscopic resection of lung bullae. Methods We recuited 76 patients who accepted thoracoscopic resection of lung bullae from February 2013 to March 2015. They were randomly divided into two groups: an intercostal nerve block and intravenous patient-controlled analgesia (INB+IPCA) group, in which 38 patients (30 males, 8 females, with a mean age of 23.63±4.10 years) received INB intraoperatively and IPCA postoperatively, and a postoperative intravenous patient-controlled analgesia (IPCA) group, in which 38 patients (33 males, 5 females, with a mean age of 24.93±6.34 years) only received IPCA postoperatively. Their general clinical data and the postoperative pain visual analogue scale (VAS) were recorded. Analgesia-associated side effects, rate of the pulmonary infection were observed. Expenses associated with analgesia during hospital were calculated. Results The score of VAS, the incidence of nausea and vomiting, fatigue and other side effects, pulmonary atelectasis and the infection rate in the INB+IPCA group were significantly lower than those in the IPCA group. Postoperative use of analgesic drugs was significantly less than that in the IPCA group. Medical expenses did not significantly increase. Conclusion INB+IPCA is beneficial for fast track surgery after thoracoscopic resection of lung bullae.
ABSTRACT
Objective To discuss the clinical application of CT-guided localization of small pulmonary nodules (SPNs) by using double-hook-wire before the performance of video-assisted thoracoscopic (VATS) resection.Methods Before the performance of VATS resection,CT-guided localization by using doublehook-wire was carried out in 54 patients with SPNs (67 small pulmonary nodules in total) and CT-guided localization by using single-hook-wire was employed in 63 patients with SPNs(81 small pulmonary nodules in total).The location success rate and complication rate of the double-hook-wire technique and the singlehook-wire technique were calculated.Results The location success rate of CT-guided localization for SPNs by using double-hook-wire performed before VATS resection in 54 patients was 100％.The incidences of pneumothorax and hemorrhage were 29.6％ (16/54) and 48.1％ (26/54) respectively.In 63 patients receiving single-hook-wire technique,the location success rate for SPNs was 98.4％ (62/63).The incidences of pneumothorax and hemorrhage were 28.5％ (18/63) and 25.4％ (16/63) respectively.Conclusion CT-guided localization for SPNs by using double-hook-wire before VATS resection can reduce the risk of failure in positioning the hook-wire,and this technique is an important supplement for other localization techniques.
ABSTRACT
Objective To prospectively evaluate the efficacy and safety of Computed Tomography (CT)-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity prior to thoracoscopic resection.And to investigate the indication for CT-guided microcoil localization for small solid pulmonary nodules and ground-glass opacity.Methods From December 2012 to February 2014,85 enrolled patients with pulmonary solid nodules and ground-glass opacity underwent CT guided microcoil localization prior to video assisted thoracoscopic surgery.The procedures of localization were performed by trailing method or routine method under CT guided percutaneous pneumocentesis.For Trailing method,the microcoil was placed with the distal part coiled adjacent to the lesion and the proximal end coiled beyond the parietal pleura.By routine method,the entire microcoil was injected adjacent to the lesion.Results CT-guided microcoil placements were successful in all ninety-one lesions,including 15 solid nodules,15 mixed ground glass opacity,and 61 pure ground glass opacity,with an average diameter of 8.75mm(5-26 mm).The Complication rate of the localization procedure was 23.5％ (20/91),with 13 cases of asymptomatic pneumothorax,and 7 cases of pulmonary hematoma.None patient required surgical intervention,nor severe Complication occurred.All patients underwent video assisted thorascopic surgery on the same day or the next few days after microcoil localization.VATS removal of the pulmonary lesions was successful in all patients.However,two of 91 microcoils were found displaced during VATS resection.The success rate of microcoil marking VATS resection for pulmonary small solid nodules and ground-glass opacity was 97.8％.Microcoil marking was required for 84.6 percent of all the resected lesions.Conclusion Preoperatively CT-guided microcoil localization for pulmonary small solid nodules and ground-glass opacity is a feasible safe and effective marking technique for video assisted thoracoscopic resection.The indication for microcoil localization in our study meet the requirement of VATS resection.
ABSTRACT
Pulmonary sequestration (PS) is a rare congenital malformation of the lower respiratory tract. The anomaly is characterized by absence of communication with the tracheobronchial tree and isolated blood supply from an anomalous systemic vessels. With the utilization of antenatal ultrasound, the diagnosis of asymptomatic neonatal PS has increased. Treatment options include observation, arterial embolization and surgical resection. The aim of the present study is to review the clinical course of PS and to share our experience with thoracoscopic resection. A total of 96 patients with PS were treated at Asan Children's Hospital between 1999 and 2010. The diagnosis of PS was established by CT in the cases managed by observation or embolization, and by tissue pathology in the surgical cases. Medical records and radiographic images were retrospectively reviewed. Thirty-nine patients were managed by embolization and 30 patients by surgery. The remaining 27 patients have been under observation without any procedures. Among 27 observation patients, 1 patient regressed completely and 10 patients were lost to follow up. Of the 39 embolizations patients, 2 had their lesion regress and sepsis was suspected after embolization. In 1 patient, the microcoil migrated to the iliac artery during the embolization procedure, and another patient developed renal abscess caused by renal artery embolization. Among 30 surgical cases, resection by thoracotomy was performed in 27 at the Department of Thoracic Surgery, and thoracoscopic resection in 3 at the Division of Pediatric Sugery. Only one wound complication ocurred. We conclud that surgical excision should be recommended for pulmonary sequestration, whether the sequestration is symptomatic or not because of the risk of infection, the low rate of natural regress, poor compliance, severe complications after embolization, and to exclude other pathology. In summary, thoracoscopic resection of the pulmonary sequestration is feasible, efficacious, safe and cosmetically superior even in neonatal period.
