    Comparison of survival results of patients with t0 and t1-2-3 in pathological t staging in patients with non-small cell lung cancer who underwent surgery after neoadjuvant treatment
    (Termedia Publishing House, 2020-01-01) Kermenli, Tayfun; Melek, Hüseyin; Bayram, Ahmet Sami; Gebitekin, Cengiz; MELEK, HÜSEYİN; BAYRAM, AHMET SAMİ; GEBİTEKİN, CENGİZ; Bursa Uludağ Üniversitesi/Tıp Fakültesi.; 0000-0003-0684-0900; 0000-0003-1822-8153; AAE-1069-2022; AAI-5039-2021; JCE-0097-2023; ABB-7580-2020
    Aim: In this study, we aimed to compare the survival results of patients who underwent neoadjuvant treatment with NSCLC between March 1997 and August 2014 and were found to have T0N0 and T1-2-3/N0.Material and methods: A hundred ninety-five patients who had complete neoadjuvant therapy, complete lung resection and lymph node dissection, and pathologically diagnosed as T0 or T1-2-3/N0, M0 were included in the study.Results: Of the 195 patients included in the study, 181 were male, 14 were female and the mean age of the patients was 57.9. The mean age of the groups was as follows: group 1: 58.1, group 2: 57.7, group 3: 59.7 and group 4: 56.8. In our series the most common complication was atelectasis (n = 19). Others were prolonged air leak (n = 16), pneumonia (n = 12), apical pleural space (n = 6), wound infection (n = 3), cardiac problems (n = 3), hematoma (n = 3), bronchopleural fistula (n = 3), empyema (n = 2), chylothorax (n = 1). The 5-year survival rate for patients in the T0N0 group was 76.3%. This rate was 71.8% in group 2, 63.6% in group 3 and 44.1% in group 4.Conclusions: Survival was found to be better in patients who underwent surgery after neoadjuvant therapy and had a complete pathological response. We believe that we can provide better results with the increase in the number of cases detected as TxN0 after the neoadjuvant treatment and prolongation of the follow-up period.

    Background Lung cancer surgery may be required for patients with a history of coronary artery bypass graft (CABG). In this study, we evaluated the general characteristics of patients, the difficulties experienced during and after lung cancer surgery and complications and mortality rates.Method Patients who were operated on for primary lung cancer between January 2012 and July 2017 in the participating centres were analysed retrospectively (n=7,530). Patients with a history of CABG (n=220) were examined in detail. This special group was analysed and compared with other patients operated on for lung cancer who did not have CABG (n=7,310) in terms of 30-day mortality and revision for haemorrhage.Results Of the 7,530 patients operated on for primary lung cancer, 2.9% were found to have undergone CABG. Surgical revision was required in the early postoperative period for 6.8% of those who had CABG and 3.5% in those who did not have CABG (p=0.009). Thirty-day (30-day) mortality was 4.5% in those who had CABG and 2.9% in those who did not have CABG (p=0.143). Further analysis of patients who had undergone CABG demonstrated that video-assisted thoracoscopic surgery (VATS) resulted in fewer complications (p=0.015). Patients with a left-sided left internal mammary artery (LIMA) graft had a higher number of postoperative complications (p=0.30).Conclusions Patients who had CABG suffered postoperative haemorrhage requiring a revision twice as often, and a tendency towards higher mortality (non-statistically significant). In patients with a history of CABG, VATS was demonstrated to have fewer complications. Patients with a LIMA graft who had a left-sided resection had more postoperative complications.

    Bronchial carcinoid tumors are primary lung neoplasms thought to originate from neuroendocrine cells, i.e. Kulchitsky cells, in the bronchial mucosa, although the type of cellular origin has not been clearly understood. A 61-year-old male patient underwent surgery and microscopic examination of the specimen revealed an anastomosing trabecular bony structure among the nests of tumor cells with round nucleus, granular chromatin, and large eosinophilic cytoplasm. Our case has been deemed worthy of being presented as bronchial carcinoid tumor with exaggerated osseous metaplasia.

    Compensatory sweating (CS) is the most common and disabling complication of endoscopic thoracic sympathectomy and represents an unmet clinical challenge. Our surgical hypothesis is to generate a parallel pathway to the damaged part of the sympathetic nerve, similar to the Kuntz nerve, by reconstructing the 2 healthy intercostal nerves, thus treating CS. Here, we present a novel videothoracoscopic technique involving bilateral intercostal nerve reconstruction in patients with severe CS after endoscopic thoracic sympathectomy.(Ann Thorac Surg 2021;111:e443-6)(c) 2021 by The Society of Thoracic Surgeons

    OBJECTIVEIn this study, we aimed to evaluate our patients with tracheal tumours treated with primary or adjuvant radiotherapy (RT) and to review the current literature on the subject.METHODSBetween 1998 and 2017, eight patients underwent RT. Their median age was 37 years (15-53). The diagnosis was adenoid cystic carcinoma in five patients, squamous cell carcinoma in three patients and mucoepidermoid carcinoma in one patient. Resection type was R0 (1), R1 (4), R2 (1), and biopsy (2). The median tumour size was 2.6 cm (2-5). Median 59.4 Gy RT (32.4-66.6) was given, and weekly cisplatin was administered to four patients concomitantly.RESULTSWith a median follow-up of 85 months (4-189), five patients were alive. The 5-year overall and disease-free survival rates were 83% and 67%, respectively. There was no local recurrence in any patient. In one patient who had a complete response with curative chemo-RT, dilatation was performed five times in 10 years because tracheal stenosis developed at 60 months.CONCLUSIONTrachea tumours are rare, and the primary treatment is surgery. Adjuvant RT is controversial in R0 cases. In unresectable cases, RT is the primary treatment modality. We believe that our treatment results will contribute to the literature on the subject.

    Evaluation of polylactide film for prevention of pericardial adhesion in a rabbit model
    (Baycinar Medical Publ-Bayçınar Tıbbi Yayıncılık, 2015-01-01) Gürbüz, Orçun; Ercan, Abdulkadir; Biçer, Murat; Kumtepe, Gencehan; Bayram, Sami; Şenkaya, Işık; Saba, Davit; BİÇER, MURAT; BAYRAM, AHMET SAMİ; ŞENKAYA SIĞNAK, IŞIK; Saba, Davit; Uludağ Üniversitesi/Tıp Fakültesi/Kalp Damar Cerrahisi Anabilim Dalı.; Uludağ Üniversitesi/Tıp Fakültesi/Göğüs Cerrahisi Anabilim Dalı.; ABC-2231-2020; ABB-7580-2020; DTC-2331-2022; DPS-9311-2022
    Background: This study aims to evaluate the efficacy of a bioabsorbable polylactide film, which was proven to be effective in preventing pelvic adhesions, in prevention of postoperative pericardial adhesions in an animal model.Methods: Forty New Zealand white rabbits were divided equally into control and treatment groups. Subjects were performed left anterior thoracotomy and partial pericardiectomy followed by epicardial abrasion. In control groups (group 1 and 2), the pericardium was left open to allow retrosternal adhesions. In treatment groups (group 3 and 4), the pericardial defect was closed with 0.02 mm bioabsorbable polylactide film. Postoperative macroscopic and microscopic evaluations were made by the same blinded observers at the end of the third week in group 1 and 3, and at the end of the sixth week in group 2 and 4.Results: Macroscopic and histopathologic examinations revealed no significant differences between control and treatment groups in terms of adhesion formation. However, polylactide film supported the growth of a mesothelium-like layer in the treatment groups.Conclusion: Although polylactide film assists in the regeneration of mesothelial cells layer, it does not prevent the development of pericardial adhesions.

    Background Function of the thoracic sympathetic chain (TSC) reportedly recovers after surgical clips are removed. Hence, this study was designed to study nerve regeneration after unclipping the TSC.Methods The bilateral TSCs of six goats were studied; the goats were separated into three groups (groups I, II, and III) during excision, clipping, and unclipping. During surgery, the TSCs were excised with a scalpel in group I and clipped in groups II and III. In group III, the clips were removed 1 month postoperatively and observed for possible nerve healing for 1 month. All TSCs were examined histologically following en block resection at 1 month postoperatively in groups I and II and at 2 months postoperatively in group III.Results Inflammation in nerve sections was noted following clip removal. Furthermore, there was significant degeneration and cell infiltration in the nerve fibers of the clipped regions. The Schwann cells around the peripheral nerve endings in the unclipped regions facilitated nerve transmission by reconstitution of myelin.Conclusion Clipping the TSC can cause histologic degeneration; however, histologic nerve regeneration occurs after unclipping.
