Metallic stent insertion and removal for post-tracheotomy and post-intubation tracheal stenosis.

PURPOSE: To study the safety and effectiveness of fluoroscopic insertion and removal of self-expandable metallic airway stent for post-tracheotomy tracheal stenosis (PTTS) and post-intubation tracheal stenosis (PITS). METHODS: We conducted a retrospective analysis of 32 patients who underwent fluoroscopic stenting from September 2011 to March 2017. The patients ranged in age from 12 to 69 years. Thirty-eight airway stents were implanted, 35 covered stents and three bare stents. Nineteen airway stents were used for 16 cases of PITS or PTTS. All patients underwent chest CT scans with/without bronchoscopy prior to stent removal. The indication of stent removal and post-interventional complications were analyzed. RESULTS: All 38 airway stents were successfully inserted. Insufficient expansion and tissue hyperplasia were most common complications after stenting. Thirty five of 38 airway stents were successfully removed fluoroscopically, with a technical success rate of 92.1%. Routine removal was performed after 2.9 ± 0.3 months, and stent restenosis was found after a mean duration of 2.7 ± 0.3 months. There were six complications of stent removal with no death. Four stents showed strut fracture after removal, of which three stent pieces retained. Two patients showed dyspnea immediately after removal and required mechanical ventilation in PTTS. One patient with PTTS lost of follow-up during a mean period of 33.7 ± 3.9 months. The one-, three- and five-year patency rates were 87.1%, 76.2% and 70.8%, respectively. There was no significant difference between PITS and PTTS. CONCLUSIONS: Fluoroscopic insertion and removal of airway stent is safe and effective for PITS and PTTS. A three-month retention time is reasonable for airway stents.

Clinical significance of differentiating post-intubation and post-tracheostomy tracheal stenosis.

BACKGROUND AND OBJECTIVE: Post-intubation tracheal stenosis (PITS) and post-tracheostomy tracheal stenosis (PTTS) are serious complications in mechanically ventilated patients. Although the aetiologies and mechanisms of PITS and PTTS are quite different, little is known about the clinical impact of differentiating one from the other. METHODS: We retrospectively conducted a chart review of 117 patients with PITS and 88 patients with PTTS who were treated with interventional bronchoscopy at Samsung Medical Center between January 2004 and December 2013. RESULTS: Compared to patients with PITS, patients with PTTS had a lower BMI, poorer performance status and more frequent neurological aetiologies, mid-to-lower tracheal lesions, total obstruction and mixed stenosis types. Although there were no differences in the number of patients who received silicone stents between the two groups, Montgomery T-tubes were more frequently used in the PTTS group than in the PITS group. The final success rate without surgery, mortality or tracheostomy in situ was higher in the PITS group than in the PTTS group (76.9% vs 63.6%, P = 0.043). Additionally, airway prosthesis removal was achieved in 46.2% of patients in the PITS group and in 33.0% of the PTTS group (P = 0.063). CONCLUSION: There were significant differences between PITS and PTTS in terms of patient and stenosis characteristics, treatment modalities and clinical outcomes. Therefore, PITS and PTTS should be considered two different entities.

Evaluation of six videolaryngoscopes in 720 patients with a simulated difficult airway: a multicentre randomized controlled trial.

BACKGROUND: Videolaryngoscopes are aggressively marketed, but independent evaluation in difficult airways is scarce. This multicentre, prospective randomized controlled trial evaluates six videolaryngoscopes in patients with a simulated difficult airway. METHODS: With ethics committee approval and written informed consent, 12 senior anaesthetists intubated the trachea of 720 patients. A cervical collar limited mouth opening and neck movement, making intubation difficult. We evaluated three unchannelled (C-MAC™ D-blade, GlideScope™, and McGrath™) and three channelled videolaryngoscopes (Airtraq™, A.P. Advance™ difficult airway blade, and KingVision™). The primary outcome was first-attempt intubation success rate. Secondary outcomes included overall success rate, laryngeal view, intubation times, and side-effects. The primary hypothesis for every videolaryngoscope was that the 95% confidence interval of first-attempt success rate is ≥90%. RESULTS: Mouth opening was decreased from 46 (sd 7) to 23 (3) mm with the cervical collar. First-attempt success rates were 98% (McGrath™), 95% (C-MAC™ D-blade), 87% (KingVision™), 85% (GlideScope™ and Airtraq™), and 37% (A.P. Advance™, P<0.01). The 95% confidence interval of first-attempt success rate was >90% only for the McGrath™. Overall success, laryngeal view, and intubation times differed significantly between videolaryngoscopes (all P<0.01). Side-effects were minor. CONCLUSIONS: This trial revealed differences in the performance of six videolaryngoscopes in 720 patients with restricted neck movement and limited mouth opening. In this setting, first-attempt success rates were 85-98%, except for the A.P. Advance™ difficult airway blade. Highest success and lowest tissue trauma rates were achieved by the McGrath™ and C-MAC™ D-blade, highlighting the importance of the videolaryngoscope blade design.

Alternative intubation techniques vs Macintosh laryngoscopy in patients with cervical spine immobilization: systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Immobilization of the cervical spine worsens tracheal intubation conditions. Various intubation devices have been tested in this setting. Their relative usefulness remains unclear. METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library for randomized controlled trials comparing any intubation device with the Macintosh laryngoscope in human subjects with cervical spine immobilization. The primary outcome was the risk of tracheal intubation failure at the first attempt. Secondary outcomes were quality of glottis visualization, time until successful intubation, and risk of oropharyngeal complications. RESULTS: Twenty-four trials (1866 patients) met inclusion criteria. With alternative intubation devices, the risk of intubation failure was lower compared with Macintosh laryngoscopy [risk ratio (RR) 0.53; 95% confidence interval (CI) 0.35-0.80]. Meta-analyses could be performed for five intubation devices (Airtraq, Airwayscope, C-Mac, Glidescope, and McGrath). The Airtraq was associated with a statistically significant reduction of the risk of intubation failure at the first attempt (RR 0.14; 95% CI 0.06-0.33), a higher rate of Cormack-Lehane grade 1 (RR 2.98; 95% CI 1.94-4.56), a reduction of time until successful intubation (weighted mean difference -10.1 s; 95% CI -3.2 to -17.0), and a reduction of oropharyngeal complications (RR 0.24; 95% CI 0.06-0.93). Other devices were associated with improved glottis visualization but no statistically significant differences in intubation failure or time to intubation compared with conventional laryngoscopy. CONCLUSIONS: In situations where the spine is immobilized, the Airtraq device reduces the risk of intubation failure. There is a lack of evidence for the usefulness of other intubation devices.

Evaluation of a smartphone camera system to enable visualization and image transmission to aid tracheal intubation with the Airtraq(®) laryngoscope.

Using three-dimensional printing, we produced adaptors to attach a smartphone with camera to the eyepiece of the Airtraq(®) laryngoscope. This low-cost system enabled a team to simultaneously view the laryngoscopy process on the smartphone screen, and also enabled image transmission. We compared the Airtraq(®) with the smartphone Airtraq(®) system in a crossover study of trainee anesthesiologists performing tracheal intubation in a manikin. We also evaluated the smartphone Airtraq(®) system for laryngoscopy and tracheal intubation in 30 patients, including image transmission to and communication with a remote instructor. In the manikin study, the smartphone Airtraq(®) system enabled instruction where both trainee and instructor could view the larynx simultaneously, and did not substantially increase the time required for intubation. In the patient study, we were able to view the larynx in all 30 patients, and the remote instructor was able to receive the images and to respond on correctness of laryngoscopy and tracheal tube placement. Tracheal intubation was successful within 90s in 19 (63 %) patients. In conclusion, use of a smartphone with the Airtraq(®) may facilitate instruction and communication of laryngoscopy with the Airtraq(®), overcoming some of its limitations.

Optimizing oxygenation and intubation conditions during awake fibre-optic intubation using a high-flow nasal oxygen-delivery system.

BACKGROUND: Awake fibre-optic intubation is a widely practised technique for anticipated difficult airway management. Despite the administration of supplemental oxygen during the procedure, patients are still at risk of hypoxia because of the effects of sedation, local anaesthesia, procedural complications, and the presence of co-morbidities. Traditionally used oxygen-delivery devices are low flow, and most do not have a sufficient reservoir or allow adequate fresh gas flow to meet the patient's peak inspiratory flow rate, nor provide an adequate fractional inspired oxygen concentration to prevent desaturation should complications arise. METHODS: A prospective observational study was conducted using a high-flow humidified transnasal oxygen-delivery system during awake fibre-optic intubation in 50 patients with anticipated difficult airways. RESULTS: There were no episodes of desaturation or hypercapnia using the high-flow system, and in all patients the oxygen saturation improved above baseline values, despite one instance of apnoea resulting from over-sedation. All patients reported a comfortable experience using the device. CONCLUSIONS: The high-flow nasal oxygen-delivery system improves oxygenation saturation, decreases the risk of desaturation during the procedure, and potentially, optimizes conditions for awake fibre-optic intubation. The soft nasal cannulae uniquely allow continuous oxygenation and simultaneous passage of the fibrescope and tracheal tube. The safety of the procedure may be increased, because any obstruction, hypoventilation, or periods of apnoea that may arise may be tolerated for longer, allowing more time to achieve ventilation in an optimally oxygenated patient.

Upper limb muscular activity and perceived workload during laryngoscopy: comparison of Glidescope(R) and Macintosh laryngoscopy in manikin: an observational study.

BACKGROUND: The interaction between operators and their working environment during laryngoscopy is poorly understood. Numerous studies have focused on the forces applied to the patient's airway during laryngoscopy, but only a few authors have addressed operator muscle activity and workload. We tested whether different devices (Glidescope(®) and Macintosh) use different muscles and how these differences affect the perceived workload. METHODS: Ten staff anaesthetists performed three intubations with each device on a manikin. Surface electromyography was recorded for eight single muscles of the left upper limb. The NASA Task Load Index (TLX) was administered after each experimental session to evaluate perceived workload. RESULTS: A consistent reduction in muscular activation occurred with Glidescope(®) compared with Macintosh for all muscles tested (mean effect size d=3.28), and significant differences for the upper trapezius (P=0.002), anterior deltoid (P=0.001), posterior deltoid (P=0.000), and brachioradialis (P=0.001) were observed. The overall NASA-TLX workload score was significantly lower for Glidescope(®) than for Macintosh (P=0.006), and the factors of physical demand (P=0.008) and effort (P=0.006) decreased significantly. CONCLUSIONS: Greater muscular activity and workload were observed with the Macintosh laryngoscope. Augmented vision and related postural adjustments related to using the Glidescope(®) may reduce activation of the operator's muscles and task workload.

Tracheal intubation in patients with odentogenous abscesses and reduced mouth opening.

BACKGROUND: Odentogenous abscesses with involvement of the facial or cervical spaces can be life-threatening and often have to be drained under general anaesthesia. Trismus and swelling can make intubation with a Macintosh laryngoscope difficult or even impossible. However, indirect laryngoscopy has been successful when conventional direct laryngoscopy has failed. Therefore, we evaluated the efficacy of the Glidescope laryngoscope in patients with odentogenous abscesses and the improvement in mouth opening after neuromuscular block. METHODS: After approval of the ethics committee, 100 patients with odentogenous abscesses were randomized to undergo tracheal intubation with the Glidescope or Macintosh laryngoscope. Success rate, visualization of the glottis, intubation duration, and need for supporting manoeuvres were evaluated. RESULTS: Intubation with the Glidescope was always successful, while conventional intubation failed in 17 out of 50 patients (P<0.0001). In all patients in whom conventional tracheal intubation failed, a subsequent attempt with the Glidescope was successful. The view at the glottis (according to Cormack and Lehane; P<0.0001), intubation duration [34 s (CI 27-41) vs 67 s (CI 52-82), mean (95% confidence interval); P=0.0001], and need for supporting manoeuvres (P<0.0001) were significantly different. The inter-incisor distance improved overall with induction of anaesthesia from 2.0 cm (CI 1.8-2.2) to 2.6 cm (CI 2.3-2.9; P<0.0001) and was correlated with the duration of symptoms. CONCLUSIONS: In patients with odentogenous abscesses, the use of a Glidescope laryngoscope was associated with significantly faster tracheal intubation, with a better view, fewer supporting manoeuvres, and a higher success rate than with a conventional laryngoscope. Improvement of the inter-incisor distance after induction of anaesthesia correlated with the duration of symptoms.

Recurrent Subglottic Stenosis in a 16-Month-Old Male in the Setting of Influenza A, Intubation, and Honey Consumption.

Recurrent episodes of subglottic stenosis are rare in the literature, and the etiologic causes are misunderstood but can be congenital, idiopathic, or iatrogenic in nature. Complications of intubation can result in subsequent inflammation and reactive processes. This case involves a 16-month-old male who suffered from a recurrent episode of subglottic stenosis in the setting of croup, influenza, and honey consumption. He had presented to the emergency department in respiratory distress after ingesting a home remedy of onion juice and honey. He had been discharged one day prior from the pediatric intensive care unit after four days of intubation and a seven-day hospital course with evidence of croup on imaging. He was readmitted, and subglottic edema and narrowing were confirmed via endoscopy, which prompted antibiotic treatment and close monitoring. After three days of monitoring and re-evaluation by bronchoscopy, the patient's condition began to improve, and no intubation was necessary. It is unclear what the cause of recurrent subglottic stenosis is due to the patient's clinical picture being clouded by a potential allergic reaction to honey versus an inflammatory reactive process post-intubation from the previous admission days prior. This case emphasizes the need for further research on the prevalence and etiology of recurrent subglottic stenosis and a deeper understanding of how to optimize diagnosis and treatment.

Management of post-intubation tracheal membrane ruptures: A practical approach.

Tracheal rupture is an infrequent, severe complication of endotracheal intubation, which can be difficult to diagnose. Post-intubation tracheal rupture (PiTR) is distinct from non-iatrogenic causes of tracheobronchial trauma and often requires different treatment. The increasing adoption of pre-hospital emergency services increases the likelihood of such complications from emergency intubations. Effective management strategies for PiTR outside specialist cardiothoracic units are possible. Two cases of severe PiTR, successfully managed non-operatively on a general medical-surgical intensive care unit, illustrate a modified approach to current standards. The evidence base for PiTR is reviewed and a pragmatic management algorithm presented.

Incidence of Airway Complications in ICU.

To show the incidence of airway complications in ICU. Endotracheal intubation is an essential skill performed by multiple medical specialists to secure a patient's airway as well as provide oxygenation and ventilation through the oral route or nose. The goal of endotracheal intubation in the emergency setting is to secure the patient's airway and obtain first-pass success. There are many indications for endotracheal intubation, including poor respiratory drive, questionable airway patency, hypoxia, and Hypercapnia. These indications are assessed by evaluating the patient's mental status, conditions that may compromise the airway, level of consciousness, respiratory rate, respiratory acidosis, and level of oxygenation. In the setting of trauma, a Glasgow Coma Scale of 8 or less is generally an indication for intubation. There are many different complications of intubation as hoarseness of voice, dental injuries, arytenoid dislocation, laryngeal stenosis, tracheal stenosis and tracheomalacia. . 150 patients who were sat in the ICU that developed certain complications. 86 patients (57.3%) were sitting in the ICU develoed certain complications. Liver diseases were the main cause of ICU admission 34 (22.7%) patients then shock 32 (21.3%) patients. Blockage of endotracheal tube was the main ICU complications 18 (12%) patients then sinusitis 16 (10.7%) patients. Endotracheal intubation is a lifesaving procedure and its complications are significant problems in ICUs. A successful procedure of intubation avoids complications. Skilled endotracheal intubation in the ICU decreases the complications.

Post-intubation tracheal stenosis in pediatric age group: single-center experiences of 24 years.

BACKGROUND AND AIM: Post-intubation tracheal stenosis (PITS) is an iatrogenic injury that involves some patients. Given the importance of this issue and the referral of a significant number of children with tracheal stenosis to Masih Daneshvari Hospital in Tehran, Iran, the present study investigated tracheal stenosis following prolonged intubation in the pediatric age group. METHODS: In this observational retrospective study, from 1994 to 2018, the medical records of all children under 14 years of age with a history of PITS were reviewed. Demographic and clinical characteristics including signs and symptoms, the underlying condition that leads to intubation, duration of intubation, type of stenosis, and the therapeutic approach, type of surgery, and follow-up were collected and analyzed using SPSS. RESULTS: Among 161 patients with a mean age of 9.8 ± 4.2 years, 69% were male. The site of stenosis was limited to the trachea in 47% and others both trachea and subglottic area were involved. The most common cause of intubation was trauma. The most common symptoms were dyspnea and wheezing. Success rates of reconstruction were 93.75% in type I, 82.15% in type II, and 35.70% in type III. Among the 16 patients who underwent Type III surgery, decannulation was not performed in 11 patients. Traction in the anastomosis and complications were stated in 26 and 10% of the patients respectively, a mortality rate of 8.7% was also reported. CONCLUSION: In the case of endotracheal intubation, PITS should be considered in the differential diagnosis of dyspnea in children as well as adults.

Prognostic Factors for Tracheal Restenosis after Stent Removal in Patients with Post-Intubation and Post-Tracheostomy Tracheal Stenosis.

PURPOSE: Long-term tracheal stent placement can increase the risk of stent-related complications; hence, removal of the stent after stabilization is attempted. However, little evidence has been established regarding the risk factors for tracheal restenosis. We aimed to identify the risk factors for tracheal restenosis in patients with post-intubation tracheal stenosis (PITS) and post-tracheostomy tracheal stenosis (PTTS). MATERIALS AND METHODS: We retrospectively analyzed patients with PITS and PTTS between January 2004 and December 2019. Patients were classified into a success or failure group according to treatment outcomes. Patients with successful stent removal were defined as patients who did not require additional intervention after stent removal during the follow-up period. Multiple logistic regression analysis was performed to identify the factors associated with tracheal restenosis. RESULTS: Among 269 stented patients, 130 patients who had removed the stent were enrolled in this study. During the follow-up period, 73 (56.2%) patients had a stable clinical course; however, 57 (43.8%) patients had restenosis. The proportion of trauma-induced intubation was higher in the success group than in the failure group (p=0.026), and the median stent length was shorter in the success group (45 mm) than in the failure group (50 mm, p=0.001). On multivariate analysis, trauma-induced intubation [adjusted odds ratio (aOR), 0.329; 95% confidence interval (CI), 0.117-0.927; p=0.036], and stent length <50 mm (aOR, 0.274; 95% CI, 0.130-0.578; p=0.001) were associated with a decreased risk of restenosis. CONCLUSION: Trauma-induced intubation and stent length were associated with successful stent removal.

The role of interventional bronchoscopy in the management of post-intubation tracheal stenosis: A 20-year experience.

PURPOSE: Benign tracheal stenosis management is still controversial, and there is no international consensus on the best treatment option. Thus, we aimed to look into the history of PITS and the different strategies used in its treatment. The importance of bronchoscopic treatment was also defined, and its effectiveness and safety were assessed. METHODS: Retrospective study of patients diagnosed with PITS, who were referred to the Bronchology Department between January 1996 and December 2016. RESULTS: Of 115 patients enrolled (mean age 48.5±17.6 years, 53% males), 66.1% had complex stenosis. The most common causes of intubation were respiratory (29.9%), neurological (26.8%) and surgical (19.6%). Complex stenosis was caused by longer intubation, and was more frequent among previously tracheostomized patients. The most common location was the upper third of trachea (60.9%). Most cases were initially treated by interventional bronchoscopy, and although serial dilations were effective in some complex PITS, a higher proportion of simple stenosis was successfully managed with this treatment option. Long-term recurrence after serial dilation was observed in 25.0% of cases. Stent placement was required (19.1%) only for complex PITS. Stent-related complications were frequent (61.9%) and linked to the stenting time (p<0.001). Overall, there were no procedure-related complications. Surgical intervention was also performed (30.0%), always with complex PITS. Post-surgical recurrences were observed in 24.2% of cases. CONCLUSIONS: Interventional bronchoscopy is an efficient and safe modality in PITS management. Further studies are needed for better classification and improved knowledge of PITS pathogenesis, and to achieve international consensus of definition to guide clinicians in their practice.

Tracheal resection and reconstruction for post-tracheostomy tracheal stenosis treated with T-tube stenting for 10 years.

We describe the case of a patient who underwent tracheal resection for post-tracheostomy stenosis following T-tube stenting for 10 years. A 32-year-old female patient with a T-tube in the trachea was referred to us. She had brain surgery for intracranial hemorrhage 10 years ago and developed a post-tracheostomy tracheal stenosis, for which she had been treated with a T-tube. At the time of referral, she was ambulatory with a cane and otherwise independent in her daily life. We assessed her stenosis and determined that it was amenable to tracheal resection as a definitive treatment. We resected the tracheal stenosis including the stoma site and performed an end-to-end tracheal anastomosis. The anastomosis was widely patent at 6 months follow-up. Long-term treatment of tracheal stenosis with T-tube does not preclude tracheal resection as a definitive treatment. A careful review of airway stenosis for resectability on a case-by-case basis is imperative.

Post intubation tracheal stenosis.

Tracheal stenosis following prolonged intubation is a relatively rare but a serious problem. However, some degree of airway injury is common following intubation, no matter whether it is prolonged or of short duration. Here, we are reporting a fifty six year old male patient who developed multiple web like tracheal stenosis following intubation with high volume low pressure cuff endotracheal tube. Subsequently, the stenosis was successfully dilated by balloon bronchoplasty.

Endoscopic and Surgical Treatment of Benign Tracheal Stenosis: A Multidisciplinary Team Approach.

PURPOSE: Surgical resection and reconstruction are considered the most appropriate approaches to treat post-intubation tracheal stenosis (PITS). Bronchoscopic methods can be utilized as palliative therapy in patients who are ineligible for surgical treatment or who develop post-surgical re-stenosis. We investigated treatment outcomes in patients with benign tracheal stenosis. METHODS: A retrospective review was performed in patients who were diagnosed with PITS. Tracheal resection was performed for operable cases, whereas endoscopic interventions were preferred for inoperable cases with a complex or simple stenosis. RESULTS: In total, 42 patients (23 treated by bronchoscopic methods, 19 treated by surgery) took part in this study. No significant differences were observed in segment length, the proportion of obstructed airways, or vocal cord distance between the two groups. In all, 15 patients in the bronchoscopic treatment group received a stent. Following the intervention, the cure rates in the bronchoscopic and surgical treatment groups were 43.47% and 94.7%, respectively. A multidisciplinary approach resulted in a cure or satisfactory outcome in 90.5% of the patients while failure was noted in 9.5% of the patients. CONCLUSION: Bronchoscopic methods are associated with a lower cure rate compared to surgery. A multidisciplinary approach was helpful for treatment planning in patients with PITS.

A randomised controlled trial comparing fibreoptic-guided tracheal intubation through two supraglottic devices: Ambu® AuraGain™ laryngeal mask and LMA® Fastrach™.

The Ambu®AuraGain™ laryngeal mask (LM) (Ambu A/S, Ballerup, Denmark) is one of the few readily available second-generation supraglottic airway devices (SADs) that offer a conduit for fibreoptic-guided endotracheal intubation. We aimed to compare fibreoptic intubation through this device with the LMA® (laryngeal mask airway) Fastrach™ (Teleflex Medical, Co. Westmeath, Ireland), which has been a recommended dedicated rescue device for the management of the unanticipated difficult airway. This randomised controlled trial compared a previously described fibreoptic score in 116 patients with no known airway pathology, who had asleep fibreoptic endotracheal intubation via either the AuraGain LM or the LMA Fastrach. Time, ease and success rate of SAD and endotracheal tube (ETT) insertion and complications were recorded. The AuraGain LM demonstrated better laryngeal alignment with 29 out of 59 patients in the AuraGain LM (AG) group having a Grade 4 view (only vocal cords visible), compared to 20 out of 54 patients in the LMA Fastrach (FT) group (P=0.003). It allowed significantly quicker and easier ETT intubation when used as a conduit. The AuraGain LM was also quicker to insert compared to the Fastrach LMA. Similar rates of minor complications, such as sore throat and dysphonia occurred in both groups. Our study indicates that when used in patients with complete muscle relaxation and no known airway pathology, the AuraGain LM achieves better laryngeal alignment and quicker, easier and more successful fibreoptic-guided ETT intubation than the Fastrach LMA.

The evaluation and surgical management of post-intubation tracheal strictures at a thoracic surgery referral centre in South Africa.

BACKGROUND: The surgical treatment of tracheal stenosis following endotracheal intubation or tracheostomy is well described in the developed world. OBJECTIVES: To describe our surgical experience with this pathology, and highlight the nuances of its diagnosis and management in South Africa. METHODS: We reviewed the clinical records and archived imaging of all patients who underwent tracheal resection and reconstruction for post-intubation tracheal stenosis between 1 July 2003 and 31 July 2014 in the Department of Cardiothoracic Surgery at Inkosi Albert Luthuli Central Hospital, Durban, South Africa. RESULTS: During the study period, 42 patients underwent tracheal resection. We evaluated the preoperative bronchoscopic characteristics of the tracheal stricture in all patients, and computed tomography (CT) was used as an adjunct in 28 (66%) patients. The stricture lengths determined by CT and intraoperative measurement were strongly correlated (r (27)=0.506, p=0.006), and the stricture lengths determined by bronchoscopy and intraoperative measurement were weakly correlated (r (41)=0.201, p=0.209). A total of 36 patients (85.7%) underwent surgery via a cervical approach and 6 (14.3%) via a right thoracotomy approach. There was no early mortality, and surgery was complicated by vocal cord palsy in 4 cases, restenosis in 2 cases, infection in 1 case and paraparesis in 1 case. CONCLUSION: Tracheal resection for the treatment of post-intubation tracheal stenosis can be undertaken safely with minimal complications in the developing world, with the vast majority of lesions approached via a cervical approach. A preoperative evaluation of the stricture using CT is an accurate technique for planning tracheal resection and reconstruction.
