Abstract Objective To present clinical experiences regarding surgical treatment of patients with severe cicatricial tracheal stenosis. Patients and methods From January 2008 to March 2020, 14 patients underwent tracheal resection and reconstruction under general anesthesia. Nine cases had cervical tracheal stenosis and five cases had thoracic tracheal stenosis. The mean diameter and length of strictured trachea was 0 − 8 mm with a mean of 4.5 ± 2.4 mm and 1 − 3 cm with a mean of 1.67 ± 0.63 cm, respectively. General anesthesia and mechanical ventilation were performed in ten cases and four patients underwent femoral arteriovenous bypass surgery due to severe stenosis. End-to-end anastomosis of trachea was performed in 13 cases and the anastomosis between trachea and cricothyroid membrane was performed in one case. Absorbable and unabsorbable sutures were used for the anterior and posterior anastomoses, respectively. Postoperative neck anteflexion was maintained by a suture between the chin and superior chest wall. The relevant data of the 14 patients were retrospectively reviewed, and the operation time, blood loss, postoperative hospital stay, postoperative complications and follow-up were retrieved. Results There was no intraoperative death. The length of resected trachea ranged from 1.5 to 4.5 cm with a mean of 1.67 ± 0.63 cm. Operation time ranged from 50 − 450 min with a mean of 142.8 ± 96.6 min and intraoperative hemorrhage ranged from 10 − 300 ml with a mean of 87.8 ± 83.6 ml. Follow-up period ranged from 5 to 43 months with a mean of 17.9 ± 10.6 months. None of the patients had recurrent laryngeal nerve paralysis during postoperative follow-up. Ten cases were discharged uneventfully. Anastomosis stenosis occurred in three cases who received interventional therapies. Bronchopleurocutaneous fistula occurred in one patient after 6 days postoperatively and further treatment was declined. Conclusion The strategies of anesthesia, mechanical ventilation, identification of stenosis lesion, the “hybrid” sutures and postoperative anteflexion are critical to be optimized for successful postoperative recovery.

Abstract Background In this study, we aimed to summarize the extremely important lesson and experience in the whole process of surgical treatments of lung tumors for the benefit of steps taken to prevent against unplanned reoperation. Methods Demographical and clinical information of 7732 patients were retrospectively retrieved and reviewed, who were diagnosed with pulmonary tumor and underwent surgical treatments from January 2016 to March 2021. Those patients who underwent unplanned reoperation for the treatment of severe complications were focused carefully and analyzed meticulously. Results A total of forty-one patients (41/7732) received 44 unplanned reoperations. Among them, eight and thirty-three patients were diagnosed with benign and malignant tumor, respectively. The incidence of unplanned reoperations seemed to be similar on both sides (Left vs. Right: 12/3231 vs. 29/4501, p = 0.103). Lobectomy plus segmentectomy is prone to reoperation (2/16, 12.5%) as compared to the other types of surgery. The complications leading to reoperation was hemothorax, including active hemorrhage (23/44, 52.3%) and clotted hemothorax (6/44, 13.6%), chylothorax (8/44, 18.2%), and the others (7/44, 15.9%) including bronchopleural fistula, torsion, or injury of right middle bronchus and pulmonary bulla rupture. The morbidity and mortality after unplanned reoperation were 17.1% (7/41) and 12.2% (5/41), respectively. Conclusions Bronchi or vessel stumps, the surgical edges of the lung parenchyma, and pleural adhesions should be checked to avoid postoperative bleeding. Prophylactic ligation of the thoracic duct should be recommended in case of the suspected oily-like exudation in the lymph node bed. Smooth expansion of the middle lobe is important to avoid narrowing and torsion before transection of the bronchus.

Abstract Background Compensatory hyperhidrosis (CH) is a frequent side effect after sympathectomy for the treatment of primary palmar hyperhidrosis. We determined the effects of demographic and clinical factors which may increase the duration of CH (DCH). Methods One hundred twenty-two patients who had undergone sympathectomies from 2014 to 2016 were retrospectively reviewed. Anxiety was evaluated using the State and Trait Anxiety Inventory score. Follow-up evaluations continued until CH remitted. A Cox proportional hazards model was used to determine the association between DCH and variables. Results DCH ranged from 5 to 27 weeks (median, 11.47 weeks). Severe CH (HR = 0.318, 95% CI, 0.136–0.741) and exacerbated anxiety 1 month post-operatively (HR = 0.816, 95% CI, 0.746–0.893) may prolong CH. A positive correlation between post-operative anxiety and DCH was common in patients with moderate or severe CH, and in cases with forearm CH. Conclusions Pre- and post-operative anxiety should be evaluated, and anti-anxiety treatment is offered to patients with moderate-to-severe CH to shorten the DCH.
