单孔胸腔镜手术在结核性脓胸治疗中的应用

目的探讨单孔胸腔镜手术治疗结核性脓胸的应用价值,并总结相关临床经验。方法回顾性分析我院胸外科2015年1月～2017年12月住院手术治疗的120例结核性脓胸患者。依据纳入、排除的相关标准,在知情同意下将纳入患者随机分为研究组(单孔胸腔镜手术组,60例)和对照组(传统开胸手术组,60例),比较两组患者的手术时间、术中出血量、术后引流量、胸腔引流管时间、术后住院时间及术后并发症。结果两组患者围术期均无死亡病例,中转开胸3例,中转开胸率为5%(3/60)。单孔胸腔镜组与传统开胸组相比较,手术时间分别为(88.00±15.77)min、(87.52±15.66)min,术中出血量分别为(236.33±15.16)mL、(443.75±43.69)mL,术后引流量分别为(423.93±41.49)m L、(663.92±16.28)mL,胸腔引流管时间分别为(2.92±0.10)d、(4.35±1.44)d,术后住院时间分别为(11.50±2.51)d、(13.65±2.52)d,两组患者的术中出血量、术后引流量、胸腔引流管时间及术后住院时间相比,差异均有统计学意义(P均0.05)。比较两组的手术时间,差异无统计学意义(P0.05)。单孔胸腔镜组术后并发症的总的发生率为6.67%(4/60),传统开胸组术后并发症的总发生率为13.33%(8/60)。结论单孔胸腔镜手术治疗结核性脓胸创伤小、并发症少、住院时间短,患者恢复快,在临床应用中值得推广。但在临床实际中应根据患者病情合理选择手术方式。

Diffuse malignant pleural mesothelioma in an urban hospital: clinical spectrum and trend in incidence over time

This retrospective analysis reviews the clinical experience of a major urban referral hospital with diffuse malignant pleural mesothelioma during the 14-year period from 1973 through 1986. Seventy-five cases of definite or equivocal mesothelioma were identified. There were four cases of primary malignant peritoneal mesothelioma, seven cases of benign fibrous mesothelioma, and 64 cases of diffuse malignant pleural mesothelioma. In 43 cases (67%) of diffuse malignant pleural mesothelioma, there was historic evidence of asbestos exposure. In 21 cases (33%), there was no known history of asbestos exposure. An increase in annual incidence of diffuse malignant pleural mesothelioma was observed over the study period, from three cases in 1973 to ten cases in 1986. Despite greater awareness of this disease, the diagnosis remains a difficult one to establish given the nonspecific symptoms, signs and radiographic appearance, variable histologic appearance, and poor diagnostic sensitivity and specificity of thoracentesis and closed pleural biopsy. Thoracotomy, thoracoscopy, and CT-guided needle biopsies gave higher yields and are the diagnostic measures of choice when diffuse malignant pleural mesothelioma is suspected.

Anatomical basis for a successful upper limb sympathectomy in the thoracoscopic era

In this clinico-anatomical study, factors potentially responsible for unsuccessful upper limb sympathectomy (ULS) by the thoracoscopic route were evaluated. This study comprised two subsets: 1) in the clinical subset, 25 patients (n = 50 sides) underwent bilateral second thoracic ganglionectomy for palmar hyperhidrosis, and factors predisposing to unsuccessful ULS were identified; and 2) in the anatomical subset, the neural connections of the first and second intercostal spaces were bilaterally dissected in 22 adult cadavers (22 right, 21 left; n = 43 sides). Alternate neural pathways (ANP) were noted in 9 of 50 sides in the 25 clinical cases (18%). In three asthenic patients (5 sides), fascia overlying the longus colli muscle mimicked the sympathetic chain. The right superior intercostal vein (SIV) was located anterior to the second thoracic ganglion in 6 of 50 sides (12%) and predisposed to troublesome bleeding in 2 of 50 cases; the SIV was posterior to the ganglion in 19 of 50 sides (38%), posing no technical problem. On the left, the SIV was noted outside the field of dissection in all but one case. A successful outcome to sympathectomy was noted in all 25 patients. A spectrum of sympathetic contributions to the first thoracic ventral ramus for the first intercostal space was noted in 37 of 43 anatomical cases (86%). These were categorized according to the arrangements of the intrathoracic ramus between the second intercostal nerve and the first thoracic ventral ramus. The cervicothoracic ganglion (37/43 cases; 86%) and an independent inferior cervical ganglion (6/43 cases; 14%) were always located above the second rib. The second thoracic ganglion was consistently located in the second intercostal space. This study demonstrates that ANPs have little clinical significance when a second thoracic ganglionectomy is undertaken. Technical failures may be avoided if the surgeon is mindful of anatomical variations at surgery.

Gas movement in the nonventilated lung at the onset of single-lung ventilation for video-assisted thoracoscopy

To assess the potential for atmospheric nitrogen to enter the nonventilated lung following the initiation of single-lung ventilation, the nonventilated lung of 10 patients undergoing video-assisted thoracoscopy was connected to the air in a water-filled spirometer, and gas movement out of and back into the lung was measured. Airway pressure from both lungs and pleural pressure from the nonventilated side were also measured. With each breath of positive-pressure ventilation to the ventilated lung prior to the thoracic cavity being opened to the atmosphere, the pressure transmitted to the opposite hemithorax generated a mean (range) tidal movement of gas in the nonventilated lung of 134 (65-265) ml. In addition, ongoing gas exchange resulted in a progressive influx of gas from the spirometer over the 110-120 s measurement period of a mean (range) volume of 155 (70-320) ml. This easily preventable influx of atmospheric nitrogen could, in theory, predispose to arterial desaturation and to delayed lung collapse after the parietal pleura is opened.     

Spontaneous regression of malignant pleural mesothelioma

We describe the spontaneous regression of a malignant pleural mesothelioma with left pleural effusion, chest pain, and a high fever (38° to 39°C) in a 37-year-old man. The patient was referred to us because multiple nodules were seen on his chest radiograph after he was successfully treated with thoracocentesis and conventional antibiotic therapy for pleural effusion. Our diagnosis was malignant pleural mesothelioma, based on histologic findings in a biopsy specimen obtained during thoracoscopy. Interestingly, the tumors markedly regressed without treatment, and the patient was doing well more than 5 months after the cancer was diagnosed. The spontaneous regression of malignant pleural mesothelioma is rare, and this may represent the first case report.
