Multivariable analysis of risk factors for enlargement of the tracheoesophageal puncture after total laryngectomy

A Multidisciplinary Approach to Secondary Tracheoesophageal Puncture for Voice Prosthesis Insertion Using Flexible Esophagoscopy

BACKGROUND

Tracheoesophageal puncture (TEP) with voice prosthesis (VP) insertion is the gold standard of surgical voice restoration in postlaryngectomy patients. The conventional technique involves rigid esophagoscopes and trocar performed by ENT surgeons alone, with technical limitations encountered in patients with cervical abnormalities - in particular those with free or rotational flap reconstructions and postradiotherapy strictures. We report our technique using flexible endoscopy which we show to be feasible and without major safety events, as a possible consideration in the anticipated difficult TEP.

METHODS

Our study describes a multidisciplinary approach to secondary TEP involving a combined upper gastrointestinal (UGI) and (Ear, Nose, and Throat) ENT procedure, under the guidance of flexible esophagoscopy, with intraoperative involvement of the speech pathologist to guide VP insertion and placement. The procedure was performed with ease without major complications.

RESULTS

We identified nine postlaryngectomy and laryngopharyngectomy patients in our institution who underwent secondary TEP with VP insertion using flexible esophagoscopy and multidisciplinary intra-operative involvement. All patients had pharyngeal reconstruction, including radial forearm free flap (n = 4), pectoralis major rotational flap (n = 3), and anterolateral thigh flap (n = 2). Eight out of nine patients underwent adjuvant radiotherapy. The technique was successfully performed in all patients. There were three cases of early TEP displacement in two patients, of which one patient had a successful repeat procedure. We found the technique advantageous in terms of feasibility and practicality compared to the conventional approach, and without intraoperative difficulties encountered in achieving the desired field of views or navigating the challenging anatomy in a free flap and post-radiotherapy patients. This includes distorted cervical anatomy, the presence of bulky and hair-bearing flap skin, and stricture formation. Minor complications in our cohort included pharyngo-esophageal spasm, TEP displacement, granulation tissue, and peri-prosthetic leaks.

CONCLUSION

Our multidisciplinary approach to secondary TEP was performed with flexible esophagoscopy without major related complications. The technique is advantageous in the surgical approach to VP insertion in postlaryngectomy and laryngopharyngectomy patients who have had radiotherapy or pharyngeal reconstruction. It allows for safe anatomical insertion and thorough evaluation of the upper aerodigestive tract for comorbid benign or malignant esophageal pathology.

A double-blind randomized clinical trial of inflammatory cytokine and pepsin levels in the saliva of patients with voice prostheses

BACKGROUND

Tracheoesophageal speech is one of the most effective method used for voice rehabilitation after laryngectomy. The main limitation is the need for periodic voice prothesis (VP) replacements. The process of developing VP usage complications is still unexplored. The aim of this study was to assess the level of cytokines (IL-1β, IL-6, IL-8, IL-10, TNFα) and pepsin in saliva as potential factors reducing VP longevity.

METHODS

Prospective double-blind randomized clinical trial was conducted (NCT04268459). Patients were randomly divided into two groups depending on VP replacement regimen (regular-every 3 months, or irregular-when complications occur). Levels of IL-1β, IL-6, IL-8, IL-10, TNFα, and pepsin in saliva samples (fasting and after eating) of laryngectomized patients were measured using ELISA tests.

RESULTS

Fifty-two patients (26 in both groups) with control group (7 patients) participated in the study. The level of IL-1β, IL-6, IL-8, IL-10, TNFα, and pepsin did not differ according to regularity of VP replacements (p = 0.301-0.801). IL-6 levels were significantly higher when VP complications occurs (p = 0.012).

CONCLUSIONS

The saliva components were not significantly different depending on the frequency of VP replacements. IL-6 plays an important role in the development of VP use complications.

Total tracheoesophageal puncture failure: A scoping review of patient characteristics and etiologies

OBJECTIVES

Tracheoesophageal prosthesis (TEP) is a common method for post-laryngectomy speech rehabilitation. Despite its common use, some patients ultimately fail TEP rehabilitation. TEP dysfunction negatively affects quality of life due to poor voice quality and need for repeated interventions to restore TEP function. Occasionally, voice rehabilitation with TEP is completely unsuccessful. We performed a scoping review to characterize the main reasons for total TEP failure, in hopes of guiding selection of optimal TEP candidates.

STUDY DESIGN

Scoping review using PubMed of all English language articles from 1990 to 2020 addressing causes of TEP failure.

METHODS

This scoping review followed the population, intervention, comparison, outcome and study (PICOS) guidelines. Total TEP failure was defined as complete loss or abandonment of TEP voice or tract. A comprehensive search strategy using PubMed's MeSH subject headings and keywords was created. Causes and rates of failure were reviewed.

RESULTS

Among 544 peer-reviewed journal articles reviewed for inclusion. Seventy articles met inclusion criteria, resulting in a total of 4928 TEP voice restoration patients for analysis. 15.2% of these patients had total TEP failure. The most common reasons for failure were dissatisfaction with voice (26.3%), leakage (17.9%), inadequate patient motivation (14.7%), comorbidities (14.2%), stoma problems (11.6%), and abandonment of TEP after dislodgement (10.6%).

CONCLUSION

Common reasons for TEP failure included voice dissatisfaction, leakage, lack of patient motivation, patient comorbidities, and stoma problems. These factors should be considered when selecting candidates for TEP voice restoration.

A custom device for managing recurrent tracheoesophageal voice prosthesis dislodgement and aspiration due to treatment refractory, severely enlarged puncture: A video case report

We report the case of a laryngectomized patient with an enlarged tracheoesophageal puncture (TEP) that is refractory to standard treatments and culminating in life-threatening recurrent dislodgement and aspiration of custom fabricated dual extra-large flange voice prostheses (VP). The fabrication and use of a novel intraluminal prosthetic device to prevent dislodgement, lessen aspiration, and preserve TE voice is described. A custom device insetting a commercial VP into the posterior wall of a LaryTube (coined "inset-VP") was devised with the primary goal of eliminating chronic VP dislodgement and lessening aspiration while maintaining TE voice. Tools required to fabricate the device included a commercial laryngectomy tube, standard-flanged commercial indwelling voice prosthesis, felt-tip marker, 6 mm biopsy punch, and silk suture. After 7 months of using an inset-VP LaryTube device, the patient has experienced zero episodes of VP aspiration. Thin liquid aspiration control is equivalent or better than prior management with custom 24-30 mm dual collar prostheses. TEP voice is fluent and functional with device in place. Novel strategies are needed to manage the rare but devastating effects of a severely enlarged TEP. Solutions to manage symptoms need to be patient-specific, aligning with their anatomy, physiology, psychosocial needs, and goals. The inset-VP device described in this report may offer improved prosthetic retention in select patients with enlarged TE puncture and frequent VP dislodgements.

Surgical closure of enlarged tracheoesophageal fistula after laryngectomy: A systematic review of techniques

OBJECTIVES

The objectives of the study were (1) systematically review the data on surgical closure of enlarged tracheoesophageal fistula after laryngectomy and (2) to perform a comparison of reconstruction of surgical techniques.

METHODS

Systematic review was performed using PRISMA methodology. Cumulative patient data were compared between patients reconstructed with vascularized tissue (sternocleidomastoid fascia and muscle, pectoralis major, deltopectoral, radial forearm) and those closed primarily (two-layer, three-layer, and tracheal transposition).

RESULTS

Fourteen studies reported outcomes for the reconstruction of tracheoesophageal fistula. Primary closure was used in 98 patients, vascularized flap in 74, and occlusive device in 8. Vascularized flap resulted in successful closure of the fistula in 89 % of cases compared to primary closure in 62 % (p = 0.0003).

CONCLUSION

Systematic review of the literature supports an improved surgical closure rate with vascularized flap interposed between the esophageal and tracheal lumens compared to primary closure.

Management of Enlarging Tracheoesophageal Fistula with Voice Prosthesis in Laryngectomized Patients

Management of Enlarging tracheoesophageal fistula (TEF) with Voice Prosthesis in Laryngectomized Head and Neck Cancer Patients.

OBJECTIVES

An enlarging TEF following voice prosthesis placement impacts patient quality of life, risks airway compromise, and can lead to aspiration pneumonia. Pharyngoesophageal strictures have previously been reported to be associated with TEF enlargement and leakage. We describe a series of patients with enlarging TEFs after Tracheoesophageal puncture (TEP) for voice prosthesis who required pharyngoesophageal reconstruction.

METHODS

Retrospective case series of laryngectomized H&N cancer patients with primary or secondary TEP who underwent surgical management for enlarging TEF site between 6/2016-11/2022.

RESULTS

Eight patients were included. The mean age was 62.8 years old. Seven patients had a history of hypothyroidism. Of seven with prior H&N radiation history, two had both historical and adjuvant radiation. Two of the eight TEPs were placed secondarily. Mean time from TEP to enlarging TEF diagnosis was 891.3 days. Radial forearm-free flaps were used in five patients. Six had stenosis proximal to the TEF whereas one had distal stenosis and one had no evidence of stenosis. Mean length of stay was 12.3 days. Mean follow-up was 400.4 days. Two required a second free flap for persistent fistula.

CONCLUSION

Surgical reconstruction of enlarging TEFs due to TEP/VP placement is effective in combination with addressing underlying pharyngeal/esophageal stenosis contributing to TEF enlargement and leakage. Radial forearm-free flaps have the additional benefit of a long vascular pedicle to access more distant and less-irradiated recipient vessels. Many fistulae are resolved after the first flap reconstruction, but some may require subsequent reconstruction in case of failure.

Protocolized awake secondary tracheoesophageal puncture with immediate voicing

Tracheoesophageal (TE) puncture with voice prosthesis placement is a common method for vocal rehabilitation in patients who have undergone total laryngectomy. Tracheoesophageal voice prosthesis (TEP) placement after laryngectomy, known as secondary TE puncture, is traditionally done in the operating room, using rigid esophagoscopy. Traditional secondary TEP placement carries a number of downsides including risks associated with general anesthesia, high cost, and technical challenges associated with anatomical variables. As a result, in-office secondary TE puncture has become an increasingly utilized procedure with many advantages but currently lacks standardization. Here, we describe a kit-based, awake, in-office secondary TE puncture with primary TEP placement technique. This technique calls for an endoscopic snare in the event there is difficulty passing the guidewire in the cranial trajectory. No surgical technique videos demonstrating in-office secondary TE puncture currently exist. Here, we present a video tutorial of our technique, breaking down the procedure into 10 steps from analgesia to voicing.

Prevention of periprosthetic leakage with double flange voice prosthesis: a systematic review and management protocol proposal

OBJECTIVE

To conduct a systematic review of the use and results of the Provox®VegaTMXtraSealTM in the prevention of periprosthetic leakage and to propose a management protocol for this voice prosthesis.

METHODS

Systematic search based on the PRISMA Statement during February 2020. Keywords were double flange, periprosthetic leakage, voice prosthesis, and laryngectomy.

RESULTS

Four articles with 315 voice prosthesis (94 XtraSeal and 221 controls) in 55 patients were found. The XtraSeal mean duration was 114.28 ± 73.2 (CI 95%, 98.29-130.26) days compared to 102.98 ± 17.74 (CI 95%, 100.62-105.35) days of the control group. Out of 266 replacements, endoprosthetic leakage was the most frequent cause in both groups (62.41%). Periprosthetic leaks were less frequent in the XtraSeal (9.62%) than in the control group (22.43%).

CONCLUSIONS

The XtraSeal could be effective in preventing periprosthetic leakage and lengthening the time between replacements. Studies with a robust methodology are necessary to confirm these results. Managing voice prosthesis is complex and requires a multidisciplinary and systematic approach by experienced professionals to reduce replacements and complications. Incorrect placement of the XtraSeal could cause a foreign body reaction and consequently inflammation, extrusion, or pressure lesions. The Tower of Hercules protocol: (1) Measurement of the tracheoesophageal fistula using the Provox® Measure, (2) Minimization of XtraSeal slack by avoiding the complete visualization of the prosthesis' blue ring, (3) Nasofibroscopic examination of the oesophageal wall confirming both flanges are in correct position; could prevent or minimize complications derived from the use of the XtraSeal.

Cost-Effectiveness Study of Double-Flange Voice Prostheses in the Treatment of Periprosthetic Leakage in Laryngectomized Patients

BACKGROUND

Tracheoesophageal speech with a voice prosthesis is considered the rehabilitation treatment of choice in laryngectomized patients. The main reasons for prosthesis failure are endoprosthetic leakage and periprosthetic leakage. The Provox XtraSeal^® stent incorporates an additional double flange on the esophageal side to prevent periprosthetic leakage. The objective of this study is to compare the duration and costs of the Provox Vega^® and Provox XtraSeal^® prostheses used in these patients in a tertiary university hospital.

MATERIALS AND METHODS

A prospective crossover case study of laryngectomees with Provox Vega^® who underwent Provox XtraSeal^® placement due to recurrent periprosthetic leaks and decreased theoretical prosthesis life. The duration and possible factors affecting voice prostheses were studied using Kaplan-Meier curves and Cox regression. A cost-effectiveness analysis was carried out from the perspective of the Spanish National Health System with an incremental cost-effectiveness calculation.

RESULTS

A total of 38 patients were recruited, 35 men and 3 women, with a mean age of 66.26 ± 9.36 years old. Information was collected from 551 voice prostheses, 484 Provox Vega^® and 68 Provox XtraSeal^®. The mean duration of Provox Vega^® was 119.75 ± 148.8 days and that of Provox XtraSeal^® was 181.99 ± 166.07 days (p = 0.002). The most frequent reason for replacement was endoprosthetic leakage in both groups: 283 (60.86%) in the case of Provox Vega^® and 29 (48.33%) in that of XtraSeal^® (p < 0.000). To obtain no cost differences (ICE ~ 0) between Provox Vega and Provox XtraSeal, the latter should cost EUR 551.63.

CONCLUSIONS

The Provox XtraSeal^® is a cost-effective option in patients with increased prosthesis replacements due to periprosthetic leakage, reducing the number of replacements, increasing the duration of the prosthesis, and providing savings compared to Provox Vega^®.

Voice Restoration and Quality of Life in Larynx Cancer

Voice restoration following laryngectomy has a significant influence on quality of life (QOL). Three main techniques exist to provide voice: esophageal speech (ES), artificial larynx (electrolarynx [EL]), and tracheoesophageal puncture (TEP). Although the EL was historically the most used technique, TEP has quickly become the gold standard. ES remains the least frequently used technique in developed countries. Technique selection must be made on an individual basis, considering the patient's cancer history and comorbidities. Ultimately, the choice in voice-restoration technique requires joint decision making with the surgeon, speech pathologist, and patient.

Platelet-Rich Plasma, an Innovative and Noninvasive Technique for Closure of Tracheoesophageal Fistula After Laryngectomy, Report of 2 Cases

An innovative and noninvasive technique for closure of persistent tracheoesophageal fistula after total laryngectomy is described. In our preliminary study, two patients were included. No clinical and radiological signs of locoregional recurrence prior to treatment were diagnosed. We performed local injections of autologous platelet-rich plasma (PRP) according to our protocol. Complete closure of the fistula was observed in both patients who were able to take normal feeding. No side effects associated with the procedure were observed. These preliminary results are encouraging to consider PRP injection before more invasive surgical techniques in the treatment of persistent tracheoesophageal fistulas after total laryngectomy.

Patient experience of the acute post-surgical period following total laryngectomy during the COVID-19 era

BACKGROUND

Total laryngectomy (TL) results in permanent functional changes requiring rapid development of complex new skills. A significant portion of this learning happens in the acute post-surgical stage. There is increasing interest in enhanced recovery after surgery (ERAS) protocols in TL; however, implementation has been difficult. COVID-19 has placed significant pressures on acute services, requiring rapid service changes for TL patients.

AIMS

To understand the acute patient experience of having a TL both before and during COVID-19.

METHODS & PROCEDURES

Semi-structured interviews using a pre-designed topic guide were conducted with 10 people who had undergone a TL within the last 2 years. Participants were recruited by their speech and language therapists using purposive sampling. Braun and Clarke's iterative approach to data collection and thematic analysis was used to generate key themes from the data.

OUTCOMES & RESULTS

Thematic analysis identified four main themes: (1) pre-operative information-giving: 'it was just words'; (2) decision-making influences: 'I just wanted them to get it all out and get it over with'; (3) coping with adjustment to the new normal: 'this is part of me now'; and (4) the importance of relationship-building: 'when you've had something like this, you need some care and understanding'.

CONCLUSIONS & IMPLICATIONS

The need for an individualized approach to TL intervention which incorporates medical and psycho-social approaches from pre-treatment to acute discharge is vital. ERAS models should be reviewed to shift beyond the medical model alone. Rapid service changes due to COVID-19 did not contribute any major changes to the acute patient-reported experience.

WHAT THIS PAPER ADDS

What is already known on the subject We know that ERAS protocols have the potential to improve patient outcomes following TL. However, the research does not consider anything other than the early oral feeding debate and it has therefore been difficult to implement ERAS protocols in current service models. COVID19 required head and neck cancer services to make quick changes to surgical pathways, with the potential that some ERAS protocols had been adopted inadvertently. In order to understand the impact of this, we need to understand the patient experience following TL both before and during COVID19. What this paper adds to existing knowledge This paper used qualitative interviews to understand the acute patient experience following TL both during and before COVID19. Findings from these interviews highlighted that people were on the most part, well prepared for the functional changes they would experience after surgery. However, people felt there were gaps in service delivery at the pre-treatment and early discharge home period. Overall, the gaps identified were from a more psycho-social need suggesting that future ERAS models of care should consider both medical and psycho-social principles to enhance patient experience and outcome. What are the potential or actual clinical implications of this work? Pre-treatment services provided to people who have a TL could be reviewed to help maximize long-term adjustment to life. Areas which could be reviewed include the method and mode of information delivery. Further work needs to be done in partnership with community services to improve the immediate discharge home experience.

Long-term outcomes and cost-effectiveness of a magnet-based valve voice prosthesis for endoprosthesis leakage treatment

PURPOSE

Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. The main reason of voice prosthesis failure is the endoprosthesis leakage. Provox ActiValve^® incorporates a magnet-based valve system to achieve active closure of the valve to treat these leakages, with the drawback of being significantly more expensive. The aim of the study was to compare the Provox Vega^® and Provox ActiValve^® duration and costs in patients with replacements increase due to endoprosthetic leakage.

METHODS

Prospective case-crossover study in laryngectomized patients with Provox Vega^® and endoprosthesis leakage to whom a Provox ActiValve^® was placed. Survival and possible factors that affect voice prosthesis were studied using Kaplan-Meier curves and Cox Proportional Hazards Regression. Cost-effectiveness analysis from the perspective of the Spanish Public National Health System with incremental cost-effectiveness calculation was performed.

RESULTS

A total of 159 prostheses were evaluated. The most frequent reason for replacement was the endoprosthesis leakage (N = 129; 83.77%) in both models. The mean duration-time of Provox Vega^® was 44.77 ± 2.82 days (CI 95%, 39.18-50.35; median 36 days), and 317.34 ± 116.8 days (CI 95% 86.66-548; median 286 days) for the Provox ActiValve^® (p < 0.000). For every replacement not made thanks to the Provox ActiValve^® there was saving of 133.97€ CONCLUSIONS: The Provox ActiValve^® is a cost-effective solution in patients with increased prosthesis replacements due to endoprosthetic leakage, reducing the number of changes and cost compared to Provox Vega^®.

Extracorporeal lung support for tracheoesophageal fistula surgical repair with free flap

Tracheoesophageal fistula results in persistent leakage of saliva into the trachea, prevents oral feeding, and predisposes to aspiration pneumonia. Large fistula closure may require a free flap to cover the defect. When the defect involves the tracheal area between the neck and the mediastinum, a tubeless field for optimal exposure can be advantageous. This article reports the use of veno-venous extracorporeal lung support, a known safe and efficient technique to support the patient's respiratory function, for this purpose. The typical veno-venous extracorporeal lung support setting includes a femoro-jugular bypass. The patient cases reported here had characteristics that precluded the use of the jugular vein, such as neck radiation dermatitis, previous radical neck dissection, and poor accessibility. Therefore a more rarely described femoro-femoral approach was used. The cases of three patients with persistent tracheoesophageal fistula who had free flap surgeries (two bi-paddled radial forearm free flap and one latissimus dorsi muscle free flap) assisted by femoro-femoral veno-venous extracorporeal lung support are reported.

Periprosthetic Leakage in Tracheoesophageal Prosthesis: Proposal of a Standardized Therapeutic Algorithm

OBJECTIVE

Periprosthetic leakage represents the most demanding long-term complication in the voice prosthesis rehabilitation. The aim of this article is to discuss the various causes of periprosthetic leakage and to propose a systematic management algorithm.

STUDY DESIGN

Retrospective cohort study.

SETTING

Otolaryngology clinic of the University Polyclinic A. Gemelli-IRCCS Foundation.

METHODS

The study included 115 patients with voice prosthesis who were treated from December 2014 to December 2019. All patients who experienced periprosthetic leakage were treated with the same step-by-step therapeutic approach until it was successful. Incidence, management, and success rate of every attempt are analyzed and discussed.

RESULTS

Periprosthetic leakage was reported 330 times by 82 patients in 1374 clinic accesses. Radiotherapy, timing of tracheoesophageal puncture, and type of total laryngectomy (primary or salvage) did not influence the incidence of periprosthetic leakage. Salvage total laryngectomy increases the risk of more clinically relevant leakages.

CONCLUSION

By using a systematic algorithm with a step-by-step standardized approach, periprosthetic leakage management could become a less treacherous issue.

Current Role of Total Laryngectomy in the Era of Organ Preservation

In this article, we aimed to discuss the role of total laryngectomy (TL) in the management of patients with larynx cancer (LC) in the era of organ preservation. Before the 1990s, TL followed by radiotherapy (RT) was the standard treatment for patients with locally advanced LC. Over the last 30 years, various types of larynx preservation (LP) programs associating induction or concurrent chemotherapy (CT) with RT have been developed, with the aim of treating locally advanced LC patients while preserving the larynx and its functions. Overall, more than two-thirds of patients included in a LP program will not require total laryngectomy (TL) and will preserve a functional larynx. However, despite these advances, the larynx is the only tumor site in the upper aero-digestive tract for which prognosis has not improved during recent decades. Indeed, none of these LP protocols have shown any survival advantage compared to primary radical surgery, and it appears that certain LC patients do not benefit from an LP program. This is the case for patients with T4a LC (extra-laryngeal tumor extension through the thyroid cartilage) or with poor pretreatment laryngeal function and for whom primary TL is still the preferred therapeutic option. Moreover, TL is the standard salvage therapy for patients with recurrent tumor after an LP protocol.

Use of double flange voice prosthesis for periprosthetic leakage in laryngectomised patients: A prospective case-crossover study

INTRODUCTION

Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. One of the main problems of voice prosthesis is the periprosthesis leakage. Provox Vega XtraSeal incorporates a double flange on the pharyngeal side of the prosthesis in order to avoid these failures. The aim of the study is to compare the device lifetime between the Provox Vega and Provox Vega XtraSeal and to examine possible related factors that influence their duration.

METHODS

Prospective case-crossover study in 20 laryngectomised patients with Provox Vega and periprothesis leakage to whom a Provox Vega XtraSeal was placed. Survival and possible factors that affect voice prosthesis were studied using Kaplan-Meier curves and Cox Proportional Hazards Regression with Schoenfeld residuals to test the possible assumptions.

RESULTS

A total of 230 prostheses were evaluated. The most frequent reason for replacement was due to an endoprosthesis leakage (n = 146, 67%) in both models. Mean lifetime of Provox Vega was 104.474 ± 7.29 days (CI 95% 90.19-118.76) and of Provox XtraSeal was 176.76 ± 26.46 days (CI 95% 124.9-228.61) (P = .012). Complementary treatment with radiotherapy demonstrated a higher device survival (P = .007).

DISCUSSION

Provox XtraSeal seems to be effective reducing the number of changes due to periprosthetic leakage, thus increasing the survival of voice prosthesis.

Influence of proton pump inhibitor therapy on occurrence of voice prosthesis complications

PURPOSE

It has been shown that the reflux of the gastric content to the proximal oesophagus influences incidence of voice prosthesis (VP) complications in laryngectomized patients. We conducted prospective randomised study to investigate the relationship between pepsin concentration in saliva and occurrence of VP complications before and after 3 months of proton pump inhibitor (PPI) therapy.

METHODS

60 laryngectomized patients with VP and 30 controls were included in the study. Saliva samples were collected in the morning and concentration of pepsin were measured by Human Pepsin (PG) ELISA kit. Thirty-Four (57%) patients reported one or more VP complication and were randomised in two groups, with and without PPI therapy, 40 mg pantoprazole per day for 3 months.

RESULTS

Patients who had longer time since last VP change had higher incidence of periprosthetic and transprosthetic leakage and Candida colonisation. Pepsin was found in all saliva samples. Median saliva pepsin concentration level did not significantly differ between laryngectomized patients and control subjects, or between patients with and without VP complications, and there was no correlation between saliva pepsin concentration levels and type of VP complication. After 3 months therapy, there was no difference in median saliva pepsin level or incidence of VP complication between patients with and without PPI therapy.

CONCLUSION

Although reflux was proposed to be associated with VP complications and pepsin was proven as a most sensitive and specific marker of EER, we did not find any statistically significant correlation between pepsin levels and occurrence of VP complications. A 3 months 40 mg pantoprazole therapy was ineffective in reduction of VP complications in our study group.

Provox 2® and Provox Vega® device life-time: a case-crossover study with multivariate analysis of possible influential factors and duration

INTRODUCTION

Tracheoesophageal speech is considered the gold standard for rehabilitation following total laryngectomy. Current literature is limited and contradictory about the possible causes of device failure. The aim of the study is to compare the device life-time between the Provox 2 and Provox Vega and to examine possible related factors that influence their duration.

METHODS

Retrospective case-crossover study in 34 laryngectomized patients who had undergone tracheoesophageal voice rehabilitation using indwelling Provox 2 and Provox Vega voice prostheses between 2010 and 2016 in a tertiary care centre.

RESULTS

A total of 440 prostheses were evaluated. The most frequent reason for replacement was due to an endoprosthesis leakage (n = 221, 64.2%) in both models. Radiotherapy increases the risk of prosthesis replacement (IRR = 1.88, p = 0.007) as well as bilateral neck dissection (IRR = 1.56, p = 0.017) in Provox 2. Age and unilateral neck dissection do not seem to influence the duration of the prosthesis. Mean life-time of Provox 2 was 106.64 days and 124.19 days for Provox Vega (p = 0.261). Complementary treatment with radiotherapy demonstrated a lower device survival (p < 0.001).

DISCUSSION

Results confirmed the non-significant differences on device life between Provox Vega and Provox 2, as well as the relevant role of radiotherapy treatment in the increase of replacements and diminution of the device duration.

The national landscape of unplanned 30-day readmissions after total laryngectomy

OBJECTIVES/HYPOTHESIS

Examine rates of readmission after total laryngectomy and determine primary etiologies, timing, and risk factors for unplanned readmission.

STUDY DESIGN

Retrospective cohort study.

METHODS

The Nationwide Readmissions Database was queried for patients who underwent total laryngectomy between January 2013 and November 2013. Patient-, procedure-, admission-, and institution-level characteristics were compared for patients with and without unplanned 30-day readmission. Outcomes of interest included rates, etiology, and timing of readmission. Multivariate logistic regression was used to identify predictors of 30-day readmission.

RESULTS

There were 2,931 total laryngectomies performed in 2013 with an unplanned readmission rate of 17.5%. Postoperative fistula accounted for 13.7% of readmissions. The odds of readmission were elevated for patients undergoing concurrent procedures, including primary tracheoesophageal fistulization (adjusted odds ratio [aOR]: 2.44, 95% confidence interval [CI]: 1.15-5.18, P = .02) and/or pedicle graft or flap procedures (aOR: 1.73, 95% CI: 1.13-2.66, P = .01). Additionally, patients with comorbid coagulopathy (aOR: 3.04, 95% CI: 1.13-8.22, P = .03), liver disease (aOR: 2.48, 95% CI: 1.08-5.71, P = .03), and valvular heart disease (aOR: 3.18, 95% CI: 1.20-8.41, P = .02) had increased risk for unplanned 30-day readmission. Private insurance and longer lengths of stay were associated with decreased odds of readmission.

CONCLUSIONS

Nearly one-fifth of total laryngectomy patients are readmitted to the hospital within 30 days of discharge. Risk factors identified in this nationally representative cohort should be carefully considered during the postoperative period to reduce preventable readmissions after total laryngectomy.

Indwelling voice prosthesis insertion after total pharyngolaryngectomy with free jejunal reconstruction

Objectives

Total pharyngolaryngectomy with free jejunal reconstruction is often performed in patients with hypopharyngeal carcinoma. However, postoperative speechlessness significantly decreases patient quality of life. We investigated whether Provox® insertion could preserve speech after total pharyngolaryngectomy with free jejunal reconstruction.

Study Design

Retrospective chart review.

Methods

A total of 130 cases of secondary Provox® insertions after total pharyngolaryngectomy with free jejunal reconstruction were analyzed. Communication outcomes were compared using the Head and Neck Cancer Understandability of Speech Subscale. Outcomes and complications associated with insertion site (jejunal insertion vs. esophageal insertion) and adjuvant irradiation therapy were also evaluated.

Results

Provox® insertion had favorable communication outcomes in 102 cases (78.4%). Neither the insertion site nor irradiation affected the communication outcome. Complications were observed in 20 cases (15.4%). Local infection was the most common complication. Free jejunal insertion, in which the resection range was enlarged, had a lower complication rate than did esophageal insertion, and its complication rate was unaffected by previous irradiation. For all patients, the hospitalization duration and duration of speechlessness were 13.4 days and 14.6 months, respectively. Patients receiving jejunal insertions had a significantly shorter hospitalization duration than did those receiving esophageal insertions. Unlike Provox®2, Provox®Vega significantly reduced the complication rate to zero.

Conclusion

For jejunal inserson of a Provox® prosthetic, a sufficient margin can be maintained during total pharyngolaryngectomy and irradiation can be performed, and satisfactory communication outcomes were observed. Provox® insertion after total pharyngolaryngectomy with free jejunal reconstruction should be considered the standard therapy for voice restoration.

Post-laryngectomy voice rehabilitation with voice prosthesis: 15 years experience of the ENT Clinic of University of Catania. Retrospective data analysis and literature review

This study reports our 15-year experience, in Sicily, with the use of voice prostheses, analysing the different variables that have influenced the success or failure of speech rehabilitation. The retrospective clinical analysis was carried out by reviewing the clinical histories of 95 patients with laryngeal cancer, in whom a voice prosthesis had been placed by trachea-oesophageal puncture between 1998 and 2013. Age, type of tumour, type of surgery, use of prior radiation therapy, type of puncture, prosthesis used and its duration, number of replacements, complications and causes for prosthetic success or failure were analysed. The results showed a mean of Harrison-Robillard-Schultz (HRS) TEP rating scale of 11.8 in primary TEP and 12.6 in secondary TEP (P =0.613). PORT did not affect overall rehabilitation success. In these patients, the mean HRS rating scale was 11.2, with long-term success of 85% (P =0.582). In patients over 70 years old, long-term success was 82.5%, with 78% in primary and 86% in secondary TEP, the mean HRS was 11.2 in primary and 12 in secondary TEP (P =0.648). In total, long-term success was 87.5%, with 84% in primary and 91% in secondary TEP. The results obtained by retrospective analysis of 15 years of prosthetic rehabilitation in the Sicilian territory highlighted standard rehabilitation, in terms of intra and postoperative complications, fistula related pathology and overall success.

Influence of timing, radiation, and reconstruction on complications and speech outcomes with tracheoesophageal puncture

BACKGROUND

We evaluated the impact of radiation, reconstruction, and timing of tracheoesophageal puncture (TEP) on complications and speech outcomes.

METHODS

Retrospective review identified 145 patients who underwent TEP between 2003 and 2007.

RESULTS

Ninety-nine patients (68%) had primary and 46 (32%) had secondary TEP, with complications occurring in 65% and 61%, respectively (p = .96). Twenty-nine patients (20%) had major complications (18 primary and 11 secondary; p = .42). Ninety-four patients (65%) had pre-TEP radiation, 39 (27%) post-TEP radiation, and 12 (8%) no radiation. With patients grouped by TEP timing and radiation history, there was no difference in complications, fluency, or TEP use. With mean 4.7-year follow-up, 82% primary and 85% secondary used TEP for primary communication (p = .66). Free-flap patients used TEP more commonly for primary communication after secondary versus primary TEP (90% vs 50%; p = .02).

CONCLUSION

Primary and secondary tracheoesophageal speakers experience similar high rates of complications. Extent of pharyngeal reconstruction, rather than radiation, may be more important in selection of TEP timing. © 2016 Wiley Periodicals, Inc. Head Neck 38: 1765-1771, 2016.

Treatment of large persistent tracheoesophageal peristomal fistulas using silicon rings

Introduction

Tracheoesophageal peristomal fistulae can often be solved by reducing the size of the fistula or replacing the prosthesis; however, even with conservative techniques, leakage around the fistula may continue in total laryngectomy patients. Also, several techniques have been developed to overcome this problem, including injections around the fistula, fistula closure with local flaps, myofascial flaps, or free flaps and fistula closure using a septal perforation silicon button.

Objective

To present the results of the application of silicon ring expanding the voice prosthesis in patients with large and persistent peri-prosthetic fistula.

Methods

A voice prosthesis was fitted to 42 patients after total laryngectomy. Leakage was detected around the prosthesis in 18 of these 42 patients. Four patients demonstrated improvement with conservative methods. Eight of 18 patients who couldn’t be cured with conservative methods were treated by using primary suture closure and 4 patients were treated with local flaps. As silicon ring was applied as a primary treatment in the 2 remaining patients and also, applied to 2 patients who had recurrence after suture repair and to 2 patients who had recurrence after local flap implementation. Silicon rings were used in a total of 6 patients due to the secondary trachea-esophageal fistula. Patients were treated with provox-1 initially and later with provox-2. At the time of leakage around the fistula, 6 patients had provox-2.

Results

Fistulae were treated successfully in 6 patients, and effective speech of patients was preserved. Patients experienced no adaptation problem. Prosthesis changing time was not different between silicon rings expanded and normal prosthesis applied patients. Silicon ring combined voice prosthesis was used 26 times; there was no recurrence in fistula complication during 29 ± 6 months follow up.

Conclusion

Silicon rings for modified expanded voice prosthesis seems to be an effective treatment for persistent peri-prosthetic leakage, for both, fistula closure and preserving the patients speech.

[Importance of cellular tight junction complexes in the development of periprosthetic leakage after prosthetic voice rehabilitation]

BACKGROUND

The use of voice prostheses is currently the gold standard in voice rehabilitation after total laryngectomy. This method combines low complication rates and excellent rehabilitation results; however, approximately 30% of patients show periprosthetic leakage or severe fistula enlargement after laryngectomy and prosthetic voice restoration within the first 4 years. The development of this enlargement is controversially discussed in the literature but recently published studies have shown that high esophageal reflux plays a key role in this process, which leads to an inflammatory reaction and disturbs the intercellular tight junctions in the sense of an epithelial mesenchymal transition (EMT).

MATERIAL AND METHODS

A total of 44 patients underwent 24 h pH monitoring, a sample biopsy from the region of the fistula and a subsequent biomolecular examination for intracellular junction proteins as well as a correlation between the severity of reflux and tracheoesophageal fistula problems before and after antireflux therapy with proton pump inhibitors (PPI).

RESULTS

Immunohistochemical staining revealed decreases in membrane E-cadherin and β-catenin and a significant increase in the cytoplasmic fraction, depending on the severity of inflammation in the fistula tissue. In patients with an improvement of clinical fistula problems under oral PPI treatment an increase of membrane E-cadherin could be shown, whereas patients with persisting fistula enlargement demonstrated a further decrease of E-cadherin.

CONCLUSION

The data indicate a central role of EMT in the development of fistula enlargement after total laryngectomy. Patients with periprosthetic leakage showed a loss of membrane bound E-cadherin and β-catenin with an up-regulation of vimentin expression. In patients with mild or no leakage problems EMT could be resolved by aggressive antireflux treatment, whereas patients without any effect of PPI treatment on the fistula showed no reversal of EMT. These data contribute to the understanding of treatment resistant fistula enlargement after total laryngectomy.

Novel modification of voice prosthesis

The undesired dilatation of the tracheooesophageal shunt after surgical implantation of voice prosthesis is a typical complication of this procedure. Temporary removal of the prosthesis and reinsertion after a short period of time is a first-line therapeutical option aiming shrinkage of the shunt. Failure of this measure generally is an indication of revision surgery. We present first experiences treating leakage problems with novel modified voice prosthesis without surgical intervention in specified cases. 11 patients (1 female, 10 male) aging between 51 and 71 years were presented with shunt leakage between 11/2008 and 11/2012 in the ENT-Department of the University Hospital of Homburg/Saar after a custom built voice prosthesis had been used initially successfully. A "Provox 2"(®) voice prosthesis was modified with two discs made of silicone each on the tracheal and oesophageal side and additionally reinforcing the diameter of the prosthesis by a silicone tube. The modified prosthesis was inserted in a retrograde way under general anesthesia, analogical to the approach used with the "Provox 1"(®)-prosthesis. The period of observation ranged between 12 and 48 months. As a measure of control swallowing of methylene blue was used. In all cases leakage suspended. Durability of the modified prosthesis ranged between 2 and 6 months. Neither the patients' complained about, nor did the physicians notice subjectively an impairment of the voice quality. Modifications of "Provox 2"(®)-prosthesis should be regarded in individual cases and constitute a reasonable alternative to revision surgery. A surgical approach is more intricate and costly, more taxing for the patient and susceptible to failure. We regard the necessity of general anesthesia for the insertion of the modified prosthesis as a disadvantage.

Reconstruction of expanding tracheoesophageal fistulae in post-radiation therapy patients who undergo total laryngectomy with a bipaddled radial forearm free flap: Report of 8 cases

BACKGROUND

Our surgical approach describes a bipaddled radial forearm free flap (RFFF) for closure of chronic tracheoesophageal fistulae (TEF) in patients who underwent total laryngectomy. The desired functional results were achieved.

METHODS

Eight patients underwent the procedure. The surgical approach includes exposure and resection of the fistula tract, and a bipaddled RFFF transfer. Key surgical maneuvers include: circumferential dissection and mobilization of the trachea; partial sternal resection in select cases; inset of flap's distal paddle into the anterior esophageal wall; and inset of the proximal skin paddle to the posterior tracheal wall and cervical skin.

RESULTS

Successful reconstruction of all 8 cases was done to restore a normal diet and a widely patent tracheal opening. One patient developed a delayed esophageal stricture, which was successfully managed with home dilation.

CONCLUSION

Several TEF treatment approaches have been reported. Our 87.5% esophageal lumen preservation success rate, reestablishment of adequate airway, and uncomplicated postoperative courses demonstrates the reliability of this surgical approach. © 2015 Wiley Periodicals, Inc.

The development and treatment of periprosthetic leakage after prosthetic voice restoration. A literature review and personal experience part I: the development of periprosthetic leakage

In the past 30 years, the use of a voice prosthesis has become the treatment of choice for the restoration of speech following laryngectomy. Not only is the placement of a voice prosthesis a simple surgical procedure, but it is also associated with a low rate of complications and an excellent success rate. Approximately, 20-30 % of all patients with voice prostheses, however, develop periprosthetic leakage with aspiration over time. Periprosthetic leakage is usually caused by an enlargement of the tracheo-oesophageal fistula and substantially affects the quality of life of the patients concerned. In a retrospective analysis of our patients, the incidence of periprosthetic leakage was 35.7 % in a total of 232 patients who underwent laryngectomy during a period of 20 years. Substantial enlargement of the tracheo-oesophageal fistula which required multiple treatments occurred in 12.5 % of the patients. In this review, the various causes of fistula enlargement are discussed on the basis of the literature and the experience that we have accumulated during the past 20 years in the management of patients with voice prostheses.

Management of advanced laryngeal cancer

Squamous cell carcinoma of the larynx continues to be the commonest head and neck cancer in many Western countries. The larynx plays a key role for many essential functions, including breathing, voice production, airway protection, and swallowing. The goals of laryngeal cancer treatment are thus to provide best possible oncologic control, while optimizing functional outcomes. In recent decades, the treatment paradigm for advanced laryngeal cancer has shifted from one of primary surgery (total laryngectomy) as gold standard, toward non-surgical organ-preserving treatment using radiotherapy or chemoradiotherapy. However, concerns have emerged regarding functional outcomes after chemoradiotherapy, as well as possible decreased overall survival in patients with laryngeal cancer. The purpose of the present review is to review surgical and non-surgical options for treatment of advanced laryngeal cancer, as well as the evidence supporting each of these.

Laryngectomy rehabilitation: a perspective from the United States of America

PURPOSE OF REVIEW

It is important on a periodic basis to evaluate and re-evaluate the standard of care in your area and to compare it to the care provided in other parts of the world. This can result in modifications and improvement in the patient's outcome.

RECENT FINDINGS

Over the last year, additional weight has been added to the medical literature regarding the value of moisture exchangers, chronic low-risk medications, the relationship between vocal rehabilitation and esophageal reflux disease, as well as the chronic concern regarding tracheo-esophageal puncture site enlargement. Multidisciplinary input remains critical for optimum success as measured not only by the vocal outcomes, but also by the quality-of-life metrics.

SUMMARY

Optimum outcomes for vocal rehabilitation following laryngectomy suggest the need for careful multidisciplinary perioperative planning and therapy. There have been improvements in tracheo-esophageal prosthesis design, moisturization, and ease of speech generation. Additional research is needed to explore the relationship between speech and chest wall kinematics, puncture site and location, prosthesis leakage, and the potential relationships to gastro-esophageal reflux disease. Future effort should be directed toward measurable improvements in the quality of life.

Relationship between radiotherapy and gastroesophageal reflux disease in causing tracheoesophageal voice rehabilitation failure

OBJECTIVE

The objective was to analyze the association of radiotherapy with gastroesophageal reflux as determinant of fistula related pathology, in voice prosthesis patients.

STUDY DESIGN

Retrospective study.

METHODS

Sixty-one laryngectomy patients were enrolled between 2005 and 2012. All patients underwent phonatory rehabilitation with voice prosthesis, along with evidence of gastroesophageal reflux disease, for which proton pump inhibitors (PPIs) were prescribed. We analyzed the occurrence of fistula-related problems among patients who received postoperative radiotherapy and those patients who did not.

RESULTS

We observed a higher rate of failure of speech rehabilitation in laryngectomy patients with gastroesphageal reflux: this occurred when they had a history of postoperative radiotherapy (45%) compared with patients who did not (17%) (P < 0.05), although all patients were treated with PPIs.

CONCLUSION

Our results seem to confirm the importance of postoperative radiotherapy with gastroesophageal reflux for the determinism of fistula-related problems.

Early risk factors for enlargement of the tracheoesophageal puncture after total laryngectomy: nodal metastasis and extent of surgery

OBJECTIVE

To determine the early risk factors for enlargement of the tracheoesophageal puncture (TEP) after total laryngectomy.

DESIGN

Retrospective cohort study.

SETTING

The University of Texas MD Anderson Cancer Center, Houston.

PATIENTS

The study included 194 patients who underwent total laryngectomy (with or without pharyngectomy) and TEP (2003-2008).

MAIN OUTCOME MEASURES

Multiple logistic regression methods were used to evaluate early risk factors for an enlarged TEP.

RESULTS

The incidence of an enlarged TEP was 18.6% (36 of 194 patients). After adjustment for follow-up time and radiotherapy history, patients with nodal metastases had a significantly higher risk of TEP enlargement (adjusted odds ratio, 6.6; 95% CI, 1.6-26.6) than those with node-negative disease. Total laryngopharyngectomy significantly increased the risk of an enlarged TEP (adjusted odds ratio, 4.5; 95% CI, 1.4-14.7) compared with simple total laryngectomy. Before multivariable adjustment, the preoperative body mass index was also significantly associated with enlargement (P for trend, .04).

CONCLUSIONS

These data suggest that 2 clinical factors-nodal staging and extent of resection-may help identify those at highest risk for TEP enlargement early after surgery. These simple indicators may ultimately aid in patient selection and prevention of an enlarged TEP after total laryngectomy.

Customization of the voice prosthesis to prevent leakage from the enlarged tracheoesophageal puncture: results of a prospective trial

OBJECTIVES/HYPOTHESIS

Customization of the tracheoesophageal (TE) voice prosthesis (VP) is often preferred over surgical closure to prevent aspiration around the VP in laryngectomized patients with an enlarged tracheoesophageal puncture (TEP), but it has not been thoroughly evaluated.

STUDY DESIGN

Single-institution prospective trial.

METHODS

A prospective trial was conducted to evaluate the effectiveness of a customized VP with the addition of an enlarged tracheal and/or esophageal collar in patients with leakage around an enlarged TEP. Absence of leakage around the VP after placement defined immediate effectiveness. Long-term success was defined by the prevention of adverse events related to leakage during the study period. Events that defined failure included: permanent gastrostomy dependence, aspiration pneumonia, and/or surgical TEP closure.

RESULTS

Twenty-one patients with enlarged TEP were enrolled (2003-2006). Insertion of a customized VP was unsuccessful in one patient; 145 customizations were performed in the remaining 20 patients (median, 3.5 customizations) during the trial period. Of the customizations, 77% (112/145) prevented leakage immediately after VP insertion. The most common adverse event was dislodgement of the prosthesis (11%) or the collar alone (7%) in 18% (26/145) of customized VP placements. Six patients who died of disease were not evaluable for long-term outcomes. Long-term success was achieved in 80% (12/15) of evaluable patients who avoided permanent gastrostomy, aspiration pneumonia, and surgical TEP closure.

CONCLUSIONS

Prosthetic customization offers an effective method to prevent leakage around the VP in many patients with an enlarged TEP, thereby preserving TE voice while avoiding surgical closure in this high-risk population.

Outcomes of elective total laryngectomy for laryngopharyngeal dysfunction in disease-free head and neck cancer survivors

OBJECTIVE

Total laryngectomy (TL) can be offered for management of chronic aspiration, radionecrosis, and/or airway compromise after head and neck cancer (HNC) treatment. The objective of this study was to evaluate functional outcomes after TL in disease-free HNC survivors.

DESIGN

Retrospective case series with chart review.

SETTING

The University of Texas MD Anderson Cancer Center.

PATIENTS

Twenty-three disease-free HNC survivors who underwent TL for laryngopharyngeal dysfunction.

INTERVENTION

TL ± pharyngectomy.

MAIN OUTCOME MEASURES

Post-TL swallowing-related (diet, gastrostomy dependence, and pneumonia rates) and communication outcomes.

RESULTS

All patients who underwent TL for dysfunction were previously treated with radiotherapy (12/23, 52%) or chemoradiotherapy (11/23, 48%). Preoperative complications included aspiration (22/23, 96%), pneumonia (16/23, 70%), tracheostomy (9/23, 39%), and stricture (7/23, 30%); 17 patients (74%) required enteral/parenteral nutrition, and 13 of 23 (57%) were nothing per oral (NPO). Rates of pneumonia, NPO status, and feeding tube dependence significantly decreased after TL (P < .001). At last follow-up after TL, all patients tolerated oral intake, but 4 (17%) required supplemental enteral nutrition. Continued smoking after radiotherapy and a preoperative history of recurrent pneumonia were significantly (P < .05) associated with final tube dependence and/or diet level. Sixteen patients (70%) underwent tracheoesophageal (TE) puncture, and 57% (13 of 23) communicated using TE voice after TL.

CONCLUSION

Salvage TL may improve health status by significantly decreasing the rate of pneumonia and improve quality of life by restoring oral intake in patients with refractory laryngopharyngeal dysfunction after HNC treatment. TE voice restoration may enhance functional outcomes in select patients treated with elective TL for dysfunction.
