ABSTRACT

Background: Anastomosis management is the main challenge of airway resection and reconstruction, and postoperative anastomotic complications, including ischemia, stenosis, dehiscence, and separation may lead to severe outcomes and a poor prognosis. The anastomotic buttress is vital in airway reconstruction, but the selection of surgical buttress and reinforcement remains controversial. We aimed to demonstrate and evaluate the buttress options of anastomosis, including their preoperative characteristics, the intraoperative process, and the incidence of postoperative complications to help address the controversy regarding anastomosis management. Methods: This retrospective study was conducted at a single institution. Patients who underwent airway reconstruction with anastomotic wrapping from Jan. 2019 to Sep. 2021 were enrolled in this study and preoperative characteristics and operational features were collected. All patients were carefully followed up by telephone and outpatient. Their postoperative complications and postoperative status after 6 months were recorded. The surgical procedures and clinical characteristics of the buttress options of anastomosis were assessed. Results: A total of 62 patients undergoing either cervical tracheal, thoracic tracheal, carinal, or secondary carinal and main bronchus resection and reconstruction were evaluated. The anastomotic buttress used included mediastinal pleural flap (24/62, 38.7%), anterior cervical muscle (14/62, 22.6%), sternocleidomastoid (2/62, 3.2%), thymus flap (12/62, 19.4%), intercostal muscle flap (2/62, 3.2%), biological patch (2/62, 3.2%), prepericardial fat (1/62, 1.6%), thyroid gland (1/62, 1.6%), pectoralis major flap (2/62, 3.2%), and omental flap (2/62, 3.2%). All procedures produced satisfactory results without short-term anastomotic complications. A follow-up for 6 months was conducted and all patients were alive postoperatively. Tracheomalacia stenosis postoperatively occurred in 3 patients and they were subsequently treated with an endotracheal stent. One patient had tumor recurrence 3 months after surgery and received adjuvant chemotherapy. Conclusions: Various anastomotic wrapping materials are used in airway reconstruction. Different utilizations of buttress are selected according to the anatomic characteristics and the reconstruction method used. This study indicated that appropriate surgical buttresses for wrapping anastomoses are legitimate alternatives to reduce the risk of anastomotic complications.

ABSTRACT

Background: Aggressive management of heart and lung transplant (HLTx) requires a team of specialists with dedicated expert to improve long-term outcomes. This study aimed to summarize practical experiences of anesthetic management in HLTx operations. Methods: This study retrospectively analyzed the anesthesia-related clinical records of 14 cases of HLTx performed from September 2015 to October 2019. Preoperative diagnoses included congenital heart disease with pulmonary arterial hypertension, idiopathic pulmonary arterial hypertension with right heart failure, end-stage cor pulmonale, dilated cardiomyopathy, end-stage heart failure with pulmonary arterial hypertension, congenital heart disease, and lung transplant failure. All recipients received intravenous-inhalation general anesthesia with single-lumen endotracheal intubation, Swan-Ganz catheterization, and transesophageal echocardiography (TEE). Results: All 14 cases of HLTx were completed successfully and the patients were transferred to the intensive care units (ICUs). The postoperative data of the 14 patients were collected from 1 month to 4 years: seven cases survived the first year, four cases died in the short term (within 30 days), and one case died within 24 h. As at the end of November 2019, eight cases were reported dead (the longest survival was 2 years 1 month and 22 days). Four cases used extracorporeal membrane oxygenation (ECMO) for cardiopulmonary support. Conclusions: The success of the HLTx was attributed to the joint efforts of the entire transplantation team. The anesthesiology team was required for experiences in anesthesia for HLTx. The key to anesthesia management was the in-depth participation in preoperative discussions and assessments. Preventing the exacerbation of right heart failure and pulmonary arterial hypertension is critical during the induction of anesthesia. Regulation and support are crucial from the withdrawal of cardiopulmonary bypass (CPB) to within 1 h of the circulation and respiratory functions undertaken independently by the donor heart and lungs.
