Transsphincteric Repair of Rectourethral Fistulas in Combination With Dartos Muscle Flap Interposition Following Radical Prostatectomy

OBJECTIVETo present our experience with a novel technique that combines the York–Mason transsphincteric approach with dartos muscle flap interposition to treat rectourethral fistulas. METHODSWe extracted records from our prospectively kept database of 35 procedures conducted for treating rectourethral fistulas during 2002–2023; the York–Mason approach was combined with dartos muscle flap interposition in five cases, performed for treating rectourethral fistulas due to radical prostatectomy, all of which were referral cases. RESULTSAll five patients were successfully treated and followed up for a median of 70.0 months without recurrence. Before the fistula repair, all had a diverting stoma. In all cases, the first voiding cystourethrogram revealed a healed fistula. The posterior and the scrotal incisions healed uneventfully. All patients reported normal voiding and no urinary incontinence. To date, the stoma has closed in three patients, all of whom had intact fecal continence and no postoperative anal stenosis. CONCLUSIONThe transsphincteric modified York–Mason approach combined with dartos muscle flap interposition resulted in complete healing of rectourethral fistulas.

Post-Intubation Tracheoesophageal Fistula: Surgical Management by Complete Cervical Tracheal Transection.

We report successful surgical management of post-intubation tracheoesophageal fistula (TEF) in an adult patient requiring long-term mechanical ventilation. A complete tracheal transection without tracheal resection, via an anterior cervical approach, followed by direct closure of tracheal and esophageal defect, and interposition of muscle flap between the suture lines and tracheal reconstruction was performed. In selected cases, this surgical procedure may be a viable alternative to traditional techniques used to treat post-intubation TEF via the anterior or lateral cervical approach.

Traumatic injuries to the trachea and bronchi: a narrative review.

ObjectiveIn this narrative review, we aim to provide a definition of traumatic tracheo-bronchial injuries as well as an approach to their diagnosis and management, including operative and non-operative strategies.BackgroundTraumatic tracheo-bronchial injuries are relatively uncommon, but are associated with a high mortality, both at the scene and among patients who survive to hospital. Management often requires an emergency airway, usually intubation over a flexible bronchoscope, followed by definitive repair.MethodsThe published literature on the diagnosis and management of traumatic airway injuries was searched through PubMed. Additional references were identified from the bibliography of relevant publications identified. The evidence was then summarized in a narrative fashion, incorporating the authors’ knowledge, experience, and perspective on the topic.ConclusionsDefinitive diagnosis of traumatic tracheo-bronchial injuries usually involves direct visualization through liberal use of bronchoscopy in addition to cross-sectional imaging to evaluate for associated injuries, notably to the great vessels and esophagus. Important considerations for management include concerns for airway obstruction, uncontrolled air leak, and mediastinitis. Early repair of injuries recognized acutely is favored in attempts to prevent the development of airway stenosis. Key operative principles include exposure, conservative debridement to preserve length when possible, creation of a tension-free anastomosis, preservation of the blood supply, and creation of a tracheostomy, particularly in polytrauma patients. An interposition muscle flap is also required, specifically in the setting of combined esophageal and airway injuries. Patients with penetrating injuries tend to have more favorable outcomes, possibly on account of fewer concomitant injuries. Selective non-operative management is also an option in the subset of patients with iatrogenic injuries to the posterior membranous wall of the trachea, and includes broad-spectrum antibiotics and surveillance bronchoscopy.

Acquired Benign Tracheoesophageal Fistula: An Alternative Tracheoplastic Technique.

We present a case of surgical management of a tracheoesophageal fistula (TEF) following prolonged intubation. After transverse tracheal division and retraction of the distal stump, direct closure of the esophageal defect and repair of the membranous tracheal defect using a synthetic bioabsorbable patch were performed, followed by interposition of muscle flap between the suture lines and tracheal reconstruction. Large TEFs, without tracheal stenosis or circumferential airway defect, associated with marked peritracheal inflammation, may be treated with this alternative tracheoplastic technique in patients deemed not suitable for tracheal resection and anastomosis.

Rectourethral Fistula Induced by Localised Prostate Cancer Treatment: Surgical and Functional Outcomes of Transperineal Repair with Gracilis Muscle Flap Interposition

BackgroundTransperineal repair of rectourethral fistula (RUF) following prostate cancer treatment with gracilis muscle flap interposition (GMFI) leads to favourable outcomes, but published data are still lacking, notably concerning functional aspects. ObjectiveTo assess surgical and functional outcomes of this treatment of RUF. Design, setting, and participantsA retrospective study was conducted in two referral hospitals including 21 patients who underwent RUF transperineal repair with GMFI between 2008 and 2020. Surgical procedureThe standard vertical perineal approach is performed for fistula dissection. Bladder and rectal defects are closed separately. After dissection from its facia, the flap is harvested, preserving its pedicle; it is brought to the perineum and placed between the urethra and the rectum to fully cover the sutures. MeasurementsFistula closure (clinical data and postoperative cystography), digestive stoma closure, and complications graded according to the Clavien-Dindo classification were reviewed. Functional results were assessed using the Urinary Symptom Profile (USP) questionnaire, anal incontinence St Mark’s score, Patient Observer Scar Assessment Scale (POSAS) score, and a nonvalidated Likert scale questionnaire assessing issues with lower extremity functionality. Results and limitationsThe median (interquartile range) follow-up was 27 (8–47) mo. Fistula closure was successful for 20 patients (95% success). Digestive stoma was closed in 10/12 shunted patients (83%). Two (9%) Clavien-Dindo grade ≥3b complications were reported (one urinoma in a kidney transplant patient and one thigh haematoma evacuation). Eighteen patients (86%) completed the postoperative questionnaire; 11/18 (61%) had significant urinary incontinence. The mean (standard deviation) USP dysuria score was 1/9 (1.2), mean St Mark’s score was 5/24 (5), mean POSAS score was 19/70 (11), mean lower extremity functionality score was 2/20 (4), and mean procedure patient satisfaction score was 9/10 (2). The retrospective design and limited number of patients are the main limitations. ConclusionsThe present study found an excellent success rate and low morbidity for RUF transperineal repair with GMFI. Functional outcomes were satisfactory despite a high urinary incontinence rate. Patient summaryWe performed an analysis of the outcomes of perineal approach surgery with muscle interposition for closing abnormal communication between the bladder and the rectum after prostate cancer treatment. This surgical technique was found to be safe to perform and provides a high success rate, with patients being satisfied despite poor urinary continence outcomes.

Management of Cervical Tracheo-Esophageal Fistula by Lateral Cervical Approach: Our Experience'.

Acquired Tracheo-esophageal fistula (TEF) is a challenging and complicated condition. The laryngeal protection is lost in acquired TEF cases due to the established connection between the esophagus and the airways leading to aspiration, pneumonia, and acute respiratory distress syndrome. Malignancy contributes to about 80% of acquired TEF. Nonmalignant causes for TEF include prolonged ventilation, trauma (iatrogenic, penetrating, or blunt injury), foreign bodies, corrosive burns, and granulomatous infections. With the advancements in critical care, the incidence of TEF post-ventilation is on the rise in recent decades. We would like to share our experience managing ten cases of nonmalignant acquired cervical TEF by the lateral cervical approach at our institute. Apart from the isolated TEF cases, one patient with concomitant tracheal stenosis was repaired simultaneously with good postoperative results. TEF was identified in two cases following removal of T-tube and solid stent respectively and was repaired successfully with lateral cervical approach with strap muscle flap interposition.

Surgical management of benign cervical tracheoesophageal fistulas: A single-tertiary academic institution experience

PurposeDespite improvements of diagnosis and management, acquired benign tracheoesophageal fistulas (AB-TEFs) remain a challenging clinical problem and a life-threating condition. In the present study, we reviewed the early results and the long-term outcomes after surgical treatment of cervical AB-TEFs treated in our institution during the last 9 years. MethodsThis retrospective study included patients who underwent transcervical repair of benign cervical AB-TEFs. Patients were identified from a prospectively filled electronic database which included patients' demographics, medical history, disease presentation, prior treatments, operative report, morbidity and mortality, hospital stay, postoperative results and follow-up information. ResultsA total of 13 patients affected by cervical AB-TEF were treated. Most of the patients (91%) in our series were treated with a lateral cervicotomic approach with interposition of either sternocleidomastoid muscle flap (72.7%) or pectoralis major myocutaneous flap (9.1%) or infrahyoid muscle flap (9.1%). The univariate analysis of showed that the etiology and surgical technique were significantly associated with immediate postoperative outcome. Esophageal diversion was removed in all patients but 3 due to their neurological status, which was the only significant factor related to post-operative oral-intake (p =0.016). We experienced 2 (18.2%) failures of the reconstruction, which occurred in patients previously treated with chemoradiation for head and neck malignancies. None of the remaining patients (72.8%) relapsed after a long-term follow-up restoring a normal oral diet was restored. ConclusionThe lateral cervicotomic approach with sternocleidomastoid flap interposition showed its effectiveness and safety in the treatment of AB-TEFs in our single-institution experience.

Muscle flaps in pulmonary infections: a case series from Northeast India

Treatment of complications due to pulmonary infections usually involves lung resection with or without debridement. Managing residual intrathoracic defects, chronic empyema, and bronchopleural fistulae after such resections poses unique challenges. We retrospectively reviewed the data of all 9 patients referred to us with complications due to pulmonary infections, including the surgical procedures, flaps used, and their outcomes between 2018 and 2019. The mean age of the patients was 30 years (range 9?48 years). The primary disease was tuberculosis in 6 (66%) patients. Complications of primary infections were pneumothorax (n = 3), auto-pneumonectomy (n = 2), organized empyema (n = 3), and recurrent hemoptysis (n = 1). Initial interventions included lobectomy (n = 2), tracheoesophageal repair (n = 1), bronchial artery embolization (n = 1), intercostal tube drainage (n = 4), and decortication(n = 1). Complications after primary interventions included bronchopleural fistula (n = 4, 45%), recurrent empyema (n = 3, 33%), tracheal stump dehiscence (n = 1, 11%) and non-resolving hemoptysis (n = 1, 11%). Pathological microorganisms were isolated in 8 (88%) patients. Secondary corrective surgical interventions along with pedicled muscle flap interposition and reinforcement were undertaken. Nine flap procedures with or without thoracoplasty were performed. There was no open thoracostomy conversion. There was one death postoperatively. A locoregional pedicled flap with or without thoracoplasty is an effective option to manage complications of pulmonary infections. The cardiothoracic surgeon should have a knowledge of the locoregional flaps of the thorax and abdomen to address such complications.

P31 SURGICAL MANAGEMENT OF ACQUIRED TRACHEOESOPHAGEAL FISTULA CAUSED BY ESOPHAGEAL DIVERTICULUM

Abstract Aim To assess the safety and feasibility of surgical treatment for acquired tracheoesophageal fistula caused by esophageal diverticulum. Background & Methods There are rare studies of the treatment for acquired tracheoesophageal fistulas (TEFs) or bronchoesophageal fistulas (BEFs) caused by traction esophageal diverticula. Between Jan. 2014 and Apr. 2019, twelve patients were admitted to our department for TEF/BEF combined with esophageal diverticula. Clinical characteristics of the twelve patients were retrospectively reviewed. Results Among the 12 orifices in the airway side, there were two at the carina, three at the right main bronchus and seven at the right intermediate bronchus. All orifices in the esophagus side opened at the diverticula wall. All TEF/BEFs received surgical treatment. Firstly, the fistula tunnels were dissected easily. Then, interrupted sutures repaired the fistula orifices in the airway membrane. A limited diverticulectomy with the fistula resection was done in the esophagus. Separate layers of repair were performed for the defect in the esophagus. The serratus anterior muscle flap interposition was performed in all 12 cases. There were no postoperative morbidity and mortality. No recurrence fistula and symptomatic diverticula occurred. The airway and esophagus were unobstructed during the follow-up period. Conclusion Acquired TEF/BEFs caused by esophageal diverticula can be treated successfully by surgery. A limitated diverticulectomy is sufficient to ensure esophagus remodeling.

Repair of Iatrogenic Recto-Urethral Fistulas : Experience of 6 Cases

I repaired iatrogenic recto-urethral fistulas (RUF) in 6 patients. All the fistulas had developed after surgery, 5 for prostate cancer (prostatectomy) and the remaining one for pelvic solitary fibrous tumor. All of them were"simple"fistulas. I performed repair using the transperineal approach with gracilis muscle flap interposition in 4 cases, and using the transsphincteric approach (modified York-Mason method) in 2, with the cooperation of general surgeons and/or plastic surgeons. All fistulas were successfully repaired. The operation time ranged from 414 to 464 minutes for transperineal repair and 246 and 253 minutes for transsphincteric repair. The blood loss ranged from 100 to 533 ml for transperineal repair and 30 and 60 ml for transsphincteric repair. Transsphincteric approach was less invasive and may be the first choice for simple RUF repair.

Anterior pedicle temporalis muscle flap interposition in the treatment of TMJ disorders

Temporomandibular joint (TMJ) disorders are a common reason for consultation. Failure of medical treatments sometimes leads to the need for one of many surgical alternatives. Our purpose was to evaluate the results of anterior pedicle temporalis muscle flap interposition in the treatment of TMJ disorders. Material and methodsFor this prospective study, we selected 18 patients who underwent TMJ surgery involving the interposition of a temporalis muscle flap according to a standardized technique, between January 1, 2009 and August 31, 2014. CT imaging was performed on all patients prior to surgery. We documented the etiology of TMJ dysfunction, pre and postoperative pain using a visual analogue scale (VAS), pre and postoperative (last consultation) mouth opening, and complications. We used the Wilcoxon test for our statistical analysis. ResultsWe observed a significant variation in preoperative and postoperative pain and mouth opening, with an average decrease in VAS values of 4.9/10 and an average increase of mouth opening of 11.1mm. No major complications were observed. DiscussionThe interposition of an anterior pedicle temporalis muscle flap in the treatment of temporomandibular joint disorder is a simple and effective technique.

Transsphincteric repair of rectourethral fistulas: 15 years of experience with the York Mason approach.

To evaluate the surgical and functional outcomes of our single institution's 15-year experience with surgically treated rectourethral fistulas using a modification of the York Mason technique. Prospectively recorded data between 2002 and 2016 of all patients who underwent transsphincteric repair of rectourethral fistula using a modified York Mason technique at Eskilstuna County Hospital, Eskilstuna, Sweden, were assessed. A total of 20 consecutive patients, including 17 referrals (85%) and three patients (15%) from our hospital have undergone the modified York Mason procedure. The surgical and functional outcomes were evaluated. Of the 20 patients, 18 were repaired successfully (90%), and one was combined with a dartos muscle interposition flap. No fistula recurrence occurred in the 18 successful repairs during the median follow-up time of 84.7 months. Before fistula repair, 12 patients (60%) underwent a diverting stoma. The remaining eight patients (40%) underwent repair and synchronous diverting stoma. We did not find any significant differences between patients in which the repair was successful compared with patients with failed repair, but diabetes, smoking and preoperative irradiation were much more frequent in the failed group. Of the 18 patients who had a successful repair, 17 patients experienced normal voiding and no urinary incontinence. One patient was suffering from postprostatectomy incontinence before rectourethral fistula repair, and was successfully treated with Scott prosthesis. All the 13 patients in whom the stoma had been closed reported intact fecal continence and no anal stenosis postoperatively. The transsphincteric modified York Mason approach offers excellent exposure and a high fistula closure rate without fecal and urinary incontinence.

Repair of Recto-Urethral Fistula with Urethral Augmentation by Buccal mucosal Graft and Gracilis Muscle Flap interposition- Our Experience

Repair of recto-urethral fistula with urethral augmentation by buccal mucosal graft and gracilis muscle flap interposition - our experience.

IntroductionRecto-urethral fistula (RUF) is a relatively rare surgical condition, the treatment of which is quite challenging. There are many causes of RUF, but 60% of them are iatrogenic following open prostatectomies, radiotherapy, brachytherapy, urethral instrumentation etc. We present a series of six cases treated at our institution.Material and methodsA retrospective study of all six patients with recto-urethral fistula treated at our centre between 2011 and 2016 was performed. The study included charting of information like age, etiology, clinical presentation, diagnostic modalities, treatment protocols, complications and recurrence. All the patients had simple direct fistulas with no previous history of repair. One patient had history of pelvic fracture following road traffic accident, one patient had a penetrating perineal injury following road traffic accident; two patients had history of Freyer's prostatectomy for benign prostatic hypertrophy; two patients had history of open radical prostatectomy performed at other centres. All patients were treated with an initial double diversion (suprapubic cystostomy and colostomy) followed by definitive surgical repair three months later. The surgical technique used was fistula excision, urethral augmentation by buccal mucosal graft, primary rectal defect repair and gracilis muscle flap interposition between the rectum and urethra.ResultsThe patients were followed up ranging from after 6 to 48 months with a mean follow-up period of 27 months. There were minimal complications such as main wound site infections, seroma at the harvested site of gracilis muscle flap, urethral stricture. There was no report of recurrence.ConclusionsFrom our experience, we conclude that this method of repair is a very efficient one without any recurrence and with minimal complications. The results were on par with all the other successful methods of recto-urethral fistula repair described in the literature.

Bronchopleural Fistula After Pneumonectomy: Risk Factors and Management, Focusing on Open-Window Thoracostomy

We evaluated principal risk factors and different therapeutic approaches for post-pneumonectomy bronchopleural fistula (BPF), focusing on open-window thoracostomy (OWT). We retrospectively reviewed all patients treated by pneumonectomy for lung cancer from 1999 to 2014; we evaluated preoperative, operative, and postoperative data; time between operation; and fistula formation, size, treatment, and predicting factors of BPF. Cumulative incidence curves for the development of BPF were drawn according to the Kaplan-Meier method. Differences between groups were assessed with the log rank test. Multivariable Cox proportional hazards regression analysis was used to assess the independent risk factors for BPF. P values <0.05 were considered significant. BPF occurred in 60 of 733 patients (8.2%). Bronchial suture with Stapler (EndoGia) (P = 0.02), right side (P = 0.003), and low preoperative albumin levels (< 3.5 g/dL) (P = 0.02) were independent predicting factors of fistula. Early BPF was treated by thoracotomic (12) or thoracoscopic (2) debridement of necrotic tissue and BPF surgical repair. Late BPF was treated by bronchoscopic application of fibrin glue (3) or endobronchial stent (1), chest tube and cavity irrigation by povidone-iodine (15). OWT was performed in 27 patients, followed by muscle flap interposition in 7 of these 27. The survival time of patients after the treatment of BPF was 29.0 months. The overall survival of patients treated by OWT was 50% at 2 years and 27 (8%) at 4 years. Correct management of BPF depends on several factors. In case of failure of different initial therapeutic approaches, we could consider OWT, followed by myoplasty.

Surgical management of acquired tracheo/bronchoesophageal fistula associated with esophageal diverticulum.

The reports on acquired tracheoesophageal fistulas (TEFs) or bronchoesophageal fistulas (BEFs) associated with traction esophageal diverticula (TED) are rare. Here, we present our experience of six cases. Between Jan. 2015 and Jun. 2016, 6 patients were admitted to our department for TEF/BEFs combined with esophageal diverticula. Clinical data of the 6 patients were retrospectively reviewed. All orifices of TEF/BEF in the esophagus side opened at the diverticula wall. The orifices in the airway side were 2 at the carina and 4 at the right intermediate bronchus. All six patients received the same intervention: a limited diverticulectomy with the fistula resection was done in the esophagus; separate layers of repair were performed for the defect in the esophagus; the muscle flap interposition was used in all six cases. All postoperative courses were uneventful. No recurrence fistula and symptomatic diverticula occurred. The airway and esophagus were patency during a median of 9-month follow-up. Acquired TEF/BEFs caused by esophageal diverticula can be treated successfully by surgery. A limited diverticulectomy is sufficient to ensure enough esophagus remodeling. Tracheo/bronchoesophageal fistula (TEF/BEF); esophagus diverticulum; acquired.

Post-Intubation Tracheoesophageal Fistula; A Nine-Year Experience

Introduction: Tracheoesophageal fistula (TEF) is a rare condition, which could be life-threatening if diagnosed late or mismanaged. Post-intubation TEF is the most common form of acquired, non-malignant TEF and is usually associated with tracheal stenosis, which makes the treatment more challenging. Here, we present our experience of managing 21 patients with post-intubation TEF. Materials & Methods: Twenty one patients including seven women and fourteen men with mean age of 38.05 years, who had post-intubation TEF were managed in our center (Massih Daneshvari Hospital, Tehran, Iran) during 2004-2013. None of the patients were operated before weaning from mechanical ventilation. Single division and closure of the fistula was performed in one patient who did not have accompanying tracheal stenosis. One-stage surgical repair including tracheal resection, anastomosis, primary closure of the esophageal defect, and muscle flap Interposition was the main treatment method in all other cases. Patients were followed up for at least two years. Results: Excellent and good results achieved in 85.7% of our patients. Major complications including permanent vocal cord paralysis and recurrence of tracheal stenosis necessitating T-tube insertion occurred in two patients (9.5%). Severe cachexia and sepsis secondary to sputum retention resulted in one mortality (4.8%). Conclusion: Surgery might provide the best treatment results along with low mortality and morbidity rates in post-intubation TEFs if performed within the proper time.
