Abstract
Introduction Evaluating mediastinal lymph nodes is crucial in determining patient survival. (1) Surgical resection after neoadjuvant treatment prolongs survival in patients with advanced lung cancer. However, mediastinal lymph nodes should [...]
Objective: Remediastinal intervention is an indispensable procedure to assess mediastinal lymph node metastasis after induction chemotherapy in patients with non-small cell lung cancer. Remediastinal interventions can be a difficult procedure because adhesions from a prior mediastinoscopy may reduce the surgeon's field of view and may cause difficulty in diagnosing a lymph node, which causes suspicion about invasion. There are several adhesion barrier procedures, which were used to prevent postoperative adhesions, but none of them provided remarkable results. There are studies including abdominal, gynecologic, and neurochirurgic surgery; however, there is no sufficient study regarding mediastinum. In this study, we have explored the role of hyaluronic acid and carboxymethylcellulose in preventing mediastinal adhesion. Methods: In our study, 21 New Zealand-type male and female rabbits--each with a weight of 2500-3500 g--were used. Three groups, each including 7 rabbits, were set up using randomized sampling method. Mediastinal dissection was performed in the first group and Seprafilm[R] was used to build adhesion inhibition. Mediastinal dissection was performed in the second group, and 0.9% NaCl was used to build adhesion inhibition. In the control group, all layers were sutured primarily after mediastinal dissection. The rabbits were sacrificed after 30 days and each group was compared with the control group, using macroscopic and microscopic adhesion criteria. Results: According to the results of our study, Seprafilm[R] was found to be statistically efficient in preventing and decreasing adhesion in mediastinum (P < .01 in macroscopic criteria, P < .05 in inflammation, and vascular proliferation criteria). Conclusion: Seprafilm[R] can be used as an adhesion barrier in prevention of adhesions that develop as a result of surgery. Keywords: Mediastinoscopy, mediastinal adhesion, remediastinoscopy, sodium hyaluronate-carboxymethylcellulose
