The voice and swallowing profile of adults with laryngotracheal stenosis before and after reconstructive surgery: A prospective, descriptive observational study

OBJECTIVES

Airway reconstruction for laryngo tracheal stenosis (LTS) improves dyspnoea. There is little evidence relating to impact upon voice and swallowing. We explored voice and swallowing outcomes in adults with LTS before and after reconstructive surgery.

DESIGN

Outcome measures were collected pre-reconstructive surgery, two-weeks post-surgery and up to 4-6 months post-surgery.

SETTING

Tertiary referral centre.

PARTICIPANTS

With ethical approval, twenty consecutive adult (≥18 years) LTS patients undergoing airway reconstruction were prospectively recruited.

MAIN OUTCOME MEASURES

These included physiological values (maximum phonation time (MPT) and fundamental frequency; penetration aspiration score, residue score), clinician-reported (GRBAS, functional oral intake score, 100ml Water Swallow Test) and patient-reported outcomes (Voice Handicap Index-10, Reflux Symptoms Index, Eating Assessment Tool, Dysphagia Handicap Index).

RESULTS

The observational study identified patient-reported and clinician-reported voice and swallow difficulties pre- and post-surgery; median and interquartile range are reported at each time point: Voice Handicap Index-10 23 (8-31); 20.5 (9-33.5), 24.5 (12.5-29); Dysphagia Handicap Index 9 (0-37); 13 (7-44); 15 (4-34); GRBAS grade 1(1-2); 2 (1-2.5); 2(1-2); 100ml Water Swallow Test volume score 16.7 (11.1-20); 14.3 (12.5-16.7); 16.7 (14.3-20.0); 100ml Water Swallow Test capacity score 16.3 ± 9.0; 11.0 ± 4.1; 12.5 ± 2.6.

CONCLUSIONS

We present the first prospective data on voice and swallowing outcomes in adults with LTS before and after reconstructive surgery. The variability of the outcomes was higher than expected but importantly, for many the voice and swallow outcomes were not within normal limits before surgery. The clinical value of the study demonstrates the need for individual assessment and management of LTS patients' voice and swallowing.

X-ray-guided self-expandable metal stent (SEMS) implantation in oesophageal malignancy as an alternative treatment

<b><br>Indroduction:</b> Significant dysphagia, aspiration pneumonia, and impossible oral nutrition in patients with unresectable or recurrent gastroesophageal malignancy or bronchial cancer invading the oesophagus with a tracheoesophageal fistula lead to cachexia. Dehiscence of the esophago-jejunal or gastroesophageal anastomosis may cause severe oesophageal haemorrhage. We believe that X-ray-guided oesophageal stent implantation (SEMS) is an alternative palliative method for microjejunostomy or full parenteral nutrition.</br> <b><br>Aim:</b> The aim of this paper was to assess the safety and efficacy of a novel X-ray-guided oesophageal stent implantation technique.</br> <b><br>Materials and methods:</b> This retrospective analysis included 54 patients (35 men and 19 women) treated for malignant dysphagia, gastroesophageal/gastrointestinal anastomotic fistula or bronchoesophageal fistula in two Surgical Units between 2010 and 2019, using a modified intravascular approach to oesophageal stent implantation.</br> <b><br>Results:</b> The presented modified intravascular method of oesophageal stent implantation was successfully performed in all described patients requiring oral nutrition restoration immediately following oesophageal stent implantation. Two patients with oesophageal anastomotic dehiscence died on postoperative days 7 and 9 due to circulatory and respiratory failure. One patient was reimplanted due to a recurrent fistula. Two patients with ruptured thoracic aneurysm and thoracic stent graft implantation due to oesophageal haemorrhage, who were implanted with an oesophageal stent, died on postoperative days 4 and 14.</br> <b><br>Conclusions:</b> The modified intravascular X-ray-guided SEMS technique may be a palliative treatment for patients with unresectable oesophageal malignancies.</br>.

Lower Cranial Nerve Schwannomas: Cohort Study and Systematic Review

BACKGROUND AND OBJECTIVES

Schwannomas originating from the lower cranial nerves (LCNS) are rare and pose a significant surgical challenge. Resection is the mainstay treatment; however, risk of treatment morbidity is considerable, and the available literature regarding differential treatment outcomes in this vulnerable population is sparse.

METHODS

A single-institution cohort study and systematic literature review of LCNS were performed.

RESULTS

Fifty-eight patients were included: 34 underwent surgical resection and 24 underwent stereotactic radiosurgery (SRS). The median age at diagnosis was 48 years (range 17-74). Presenting symptoms were dysphagia (63%), dysarthria/hypophonia (47%), imbalance (33%), and hearing loss/tinnitus (30%). Tumor size was associated with surgical resection, as compared with initial SRS (4.1 cm vs 1.5 cm, P = .0001). Gross total resection was obtained in 52%, with tumor remnants predominantly localized to the jugular foramen (62%). Post-treatment worsening of symptoms occurred in 68% of surgical and 29% of SRS patients ( P = .003). Postoperative symptoms were mostly commonly hypophonia/hoarseness (63%) and dysphagia (59%). Seven patients (29%) had new neurological issues after SRS treatment, but symptoms were overall milder. The median follow-up was 60 months (range 12-252); 98% demonstrated meaningful clinical improvement. Eighteen surgical patients (53%) underwent adjuvant radiation at a median of 5 months after resection (range 2-32). At follow-up, tumor control was 97% in the surgical cohort and 96% among SRS patients.

CONCLUSION

Although LCNS resection is potentially morbid, most postoperative deficits are transient, and patients achieve excellent tumor control-particularly when paired with adjuvant SRS. For minimally symptomatic patients undergoing surgical intervention, we advise maximally safe resection with intracapsular dissection to preserve nerve integrity where possible. For residual or as a primary treatment modality, SRS is associated with low morbidity and high rates of long-term tumor control.

[Curriculum "Tracheostomy management in dysphagia therapy"]

The number of tracheotomized patients with dysphagia and their need for treatment are continuously increasing in clinical and community settings. The revised version of the directive on home care and community-based intensive care of the Federal Joint Committee (G-BA) requires that tracheotomized patients are regularly evaluated with the aim of identifying and promoting the therapeutic potential after hospital discharge. Dysphagia treatment plays a crucial role as without improvement of severe dysphagia there is practically no possibility for decannulation. Tracheotomized patients with dysphagia are treated by speech and language therapists (SLT); however, the contents of tracheostomy management (TM) are not obligatory in the speech and language therapeutic training curricula, so that there is a need for further education and treatment standards must be secured. Therefore, the German Interdisciplinary Society for Dysphagia (DGD) in cooperation with the participating German medical and therapeutic societies developed a postgraduate curriculum for TM. This should serve as the basis for contents in TM and qualification of therapists within the framework of the delegation of medical services. The goals of the TM curriculum are the definition of theoretical and practical contents of TM, the qualification to perform TM according to current standards of care and quality assurance. The curriculum defines two qualification levels (user and trainer), entry requirements, curricular contents, examination and qualification criteria as well as transitional regulations for SLTs already experienced in TM.

Laparoscopic Large Hiatal Hernia Repair With RefluxStop: Outcomes of Six Months Follow-up in Thirty Patients

OBJECTIVE

The antireflux surgical technique with the RefluxStop device is one of the latest approaches to treating patients with gastroesophageal reflux disease (GERD). The aim of this study was to assess the safety and feasibility of laparoscopic hiatal hernia (HH) repair with the RefluxStop device in patients with GERD and concurrent large HH (≥4 cm).

PATIENTS AND METHODS

A retrospective chart review was performed for the first 30 patients with a large HH who consented and underwent HH surgery with the RefluxStop device. The operative technique and outcomes were evaluated to assess safety and feasibility, HH recurrence, dysphagia, and patient satisfaction.

RESULTS

Between May 2020 and April 2022, 30 patients underwent laparoscopic HH repair with the RefluxStop device. All patients had typical symptoms of GERD, such as heartburn and regurgitation, and 15 patients (50%) had preoperative dysphagia. Median HH size was 5 cm (interquartile range, 4 to 5). Median operating time was 56 minutes (interquartile range, 52 to 63), with no intra and postoperative complications related to the device. One patient required laparotomy due to adhesions and associated bleeding when accessing the abdomen. All patients had postoperative imaging (video fluoroscopy) on postoperative day 1 and at 3 months, confirming the correct location of the RefluxStop device. One patient (3.3%) needed postoperative balloon dilatation due to severe dysphagia. Reflux symptoms (heartburn and acid regurgitation) resolved significantly in all patients ( P < 0.001) at 6 months. One episode of recurrence of HH (3.3%) occurred during the follow-up period of 6 months.

CONCLUSION

This study demonstrates the short-term safety and feasibility of laparoscopic HH repair with the RefluxStop device in patients with large HH, with a low rate of postoperative dysphagia and subsequent improvement or resolution of reflux symptoms in all patients.

MAGNETIC SPHINCTER AUGMENTATION DEVICE FOR GASTROESOPHAGEAL REFLUX DISEASE: EFFECTIVE, BUT POSTOPERATIVE DYSPHAGIA AND RISK OF EROSION SHOULD NOT BE UNDERESTIMATED. A SYSTEMATIC REVIEW AND META-ANALYSIS

BACKGROUND

Magnetic ring (MSA) implantation in the esophagus is an alternative surgical procedure to fundoplication for the treatment of gastroesophageal reflux disease.

AIMS

The aim of this study was to analyse the effectiveness and safety of magnetic sphincter augmentation (MSA) in patients with gastroesophageal reflux disease (GERD).

METHODS

A systematic literature review of articles on MSA was performed using the Medical Literature Analysis and Retrieval System Online (Medline) database between 2008 and 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies.

RESULTS

A total of 22 studies comprising 4,663 patients with MSA were analysed. Mean follow-up was 27.3 (7-108) months. The weighted pooled proportion of symptom improvement and patient satisfaction were 93% (95%CI 83-98%) and 85% (95%CI 78-90%), respectively. The mean DeMeester score (pre-MSA: 34.6 vs. post-MSA: 8.9, p=0.03) and GERD-HRQL score (pre-MSA: 25.8 vs. post-MSA: 4.4, p<0.0001) improved significantly after MSA. The proportion of patients taking proton pump inhibitor (PPIs) decreased from 92.8 to 12.4% (p<0.0001). The weighted pooled proportions of dysphagia, endoscopic dilatation and gas-related symptoms were 18, 13, and 3%, respectively. Esophageal erosion occurred in 1% of patients, but its risk significantly increased for every year of MSA use (odds ratio - OR 1.40, 95%CI 1.11-1.77, p=0.004). Device removal was needed in 4% of patients.

CONCLUSIONS

Although MSA is a very effective treatment modality for GERD, postoperative dysphagia is common and the risk of esophageal erosion increases over time. Further studies are needed to determine the long-term safety of MSA placement in patients with GERD.

Comparison of swallowing disorder in patients with tongue cancer undergoing reconstruction with either a radial forearm free flap or a submental island flap

PURPOSE

In this study, the swallowing status of patients with tongue cancer undergone tongue reconstruction using radial forearm free flaps (RFFF) and submental flaps were compared.

METHODS

A total of 26 patients with tongue cancer undergone tongue resection were randomly treated by tongue reconstruction with either submental flap or RFFF approach. Swallowing status of the patients was investigated using fiberoptic endoscopic evaluation of swallowing (FEES) by measurement of pharyngeal residue and penetration scales.

RESULTS

The pharyngeal residue scale in vallecula and pyriform sinus and the average of vallecula and pyriform sinus on days 10 and 30 post-operation as well as penetration scale at the same time showed no significant difference between two groups. However, the time to start oral feeding was significantly reduced in the submental group compared to the free flap group (P = 0.031). A positive Pearson correlation was found between the size of oral tongue and base of tongue resection and some of swallowing parameters.

CONCLUSION

Since there was no significant difference between submental and free flap respected to swallowing disorder, the submental flap is prior to free flap due to lower cost and hospitalization and less complication after tongue reconstruction.

Early Voice and Swallowing Disturbance Incidence and Risk Factors After Revision Anterior Cervical Discectomy and Fusion Using a Multidisciplinary Surgical Approach: A Retrospective Cohort Evaluation of a Prospective Database

BACKGROUND AND OBJECTIVES

Dysphagia and vocal cord palsy (VCP) are common otolaryngological complications after revision anterior cervical discectomy and fusion (rACDF) procedures. Our objective was to determine the early incidence and risk factors of VCP and dysphagia after rACDF using a 2-team approach.

METHODS

Single-institution, retrospective analysis of a prospectively collected database of patients undergoing rACDF was enrolled from September 2010 to July 2021. Of 222 patients enrolled, 109 patients were included in the final analysis. All patients had prior ACDF surgery with planned revision using a single otolaryngologist and single neurosurgeon. MD Anderson Dysphagia Inventory and fiberoptic endoscopic evaluation of swallowing (FEES) were used to assess dysphagia. VCP was assessed using videolaryngostroboscopy.

RESULTS

Seven patients (6.7%) developed new postoperative VCP after rACDF. Most cases of VCP resolved by 3 months postoperatively (mean time-to-resolution 79 ± 17.6 days). One patient maintained a permanent deficit. Forty-one patients (37.6%) reached minimum clinically important difference (MCID) in their MD Anderson Dysphagia Inventory composite scores at the 2-week follow-up (MCID decline of ≥6), indicating new clinically relevant swallowing disturbance. Forty-nine patients (45.0%) had functional FEES Performance Score decline. On univariate analysis, there was an association between new VCPs and the number of cervical levels treated at revision ( P = .020) with long-segment rACDF (≥4 levels) being an independent risk factor ( P = .010). On linear regression, there was an association between the number of levels treated previously and at revision for FEES Performance Score decline ( P = .045 and P = .002, respectively). However, on univariate analysis, sex, age, body mass index, operative time, alcohol use, smoking, and individual levels revised were not risk factors for reaching FEES Performance Score decline nor MCID at 2 weeks postoperatively.

CONCLUSION

VCP is more likely to occur in long-segment rACDF but is often temporary. Clinically relevant and functional rates of dysphagia approach 37% and 45%, respectively, at 2 weeks postoperatively after rACDF.

Short-term results of laparoscopic anti-reflux surgery with the RefluxStop device in patients with gastro-esophageal reflux disease and ineffective esophageal motility

PURPOSE

In gastro-esophageal reflux disease (GERD) requiring surgical treatment, concomitant ineffective esophageal motility (IEM) is a decisive factor in surgical planning, due to concern regarding dysphagia. Anti-reflux surgery with the RefluxStop device is a promising technique. We assessed initial feasibility and clinical outcomes of RefluxStop surgery in patients with GERD and IEM.

METHODS

Retrospective analysis of patients with GERD, hiatal hernia (HH), and IEM, who underwent surgery with RefluxStop at our institution and achieved 12-month follow-up. Technique feasibility was assessed, in addition to symptom resolution (GERD-HRQL questionnaire), adverse events, HH recurrence, dysphagia, and patient satisfaction. Placement of the device was confirmed by video fluoroscopy on postoperative day 1, and at 3 and 12 months.

RESULTS

Between June 2020 and November 2022, 20 patients with IEM underwent surgery with RefluxStop and completed 12-month follow-up. All patients reported typical symptoms of GERD, and 12 had preoperative dysphagia. The median HH length was 4.5 cm (IQR, 3.75-5). The median operating time was 59.5 min (IQR, 50.25-64) with no implant-related intra- or postoperative complications. No HH recurrence was observed. One patient reported persistent left-sided thoracic pain at 11 months post-surgery, which required diagnostic laparoscopy and adhesiolysis. Three patients reported severe postoperative dysphagia: balloon dilatation was performed towards resolution. The mean GERD-HRQL scores improved (from 40.7 at baseline to 4.8 at 3 months and 5.7 at 12 months (p <0.001)).

CONCLUSION

RefluxStop surgery was feasible and offered effective treatment for this group of patients with GERD and IEM. All patients had complete resolution or significant improvement of GERD symptoms, and 90% of them were satisfied with their quality of life 1 year after surgery.

Laparoscopic Approach to Epiphrenic Diverticula Under Endoscopic Assistance: A Technical Report

Introduction: Epiphrenic diverticulum is a rare disease caused by mucosa and submucosa herniation through the muscular layers of the esophageal wall. This study presents a case of a patient with a symptomatic epiphrenic diverticulum treated with surgery under endoscopic assistance. A review of the literature on this unusual condition was conducted, focusing on the pathogenesis, presentation, and surgical challenges. Methods: A 75-year-old woman who underwent an esophagogastroduodenoscopy (EGD) after experiencing worsening dysphagia for food and liquids. The EGD revealed a large epiphrenic diverticulum 36 cm from the upper incisor teeth. The presence of a diverticulum was verified by barium swallow, which revealed a 6 cm diameter epiphrenic diverticulum on the right side of the esophagus. Results: Patient underwent laparoscopic diverticulectomy associated with Heller's myotomy and anterior partial fundoplication. A gastroscope was placed intraoperatively to calibrate the esophagus to prevent stenosis during diverticulectomy, and it was also used to check the integrity of the esophageal wall. The patient tolerated clear liquids on postoperative day 2. Postoperative course was complicated by right pleural effusion and fever managed with antibiotics and pleural drainage. Conclusion: Epiphrenic diverticulectomy in conjunction with management of the underlying motor dysfunction and avoidance of gastroesophageal reflux disease is an effective procedure. Laparoscopy is considered the approach of choice for the majority of patients. Endoscopic assistance during surgery can help the identification of the diverticulum and verify the integrity of the staple line.

Impedance planimetry (EndoFLIPTM) and surgical outcomes after Hill compared to Toupet fundoplication

INTRODUCTION

Endoluminal functional lumen imaging probe (EndoFLIP) provides a real-time assessment of gastroesophageal junction (GEJ) compliance during fundoplication. Given the limited data on EndoFLIP measurements during the Hill procedure, we investigated the impact of the Hill procedure on GEJ compliance compared to Toupet fundoplication.

METHODS

Patients who underwent robotic Hill or Toupet fundoplication with intraoperative EndoFLIP between 2017 and 2022 were included. EndoFLIP measurements of the GEJ included cross sectional surface area (CSA), intra-balloon pressure, high pressure zone length (HPZ), distensibility index (DI), and compliance. Subjective reflux symptoms, gastroesophageal reflux disease-health related quality of life (GERD-HRQL) score, and dysphagia score were assessed pre-operatively as well as at short- and longer-term follow-up.

RESULTS

One-hundred and fifty-four patients (71.9%) had a Toupet fundoplication while sixty (28%) patients underwent the Hill procedure. The CSA [27.7 ± 10.9 mm2 vs 42.2 ± 17.8 mm2, p < 0.0001], pressure [29.5 ± 6.2 mmHg vs 33.9 ± 8.5 mmHg, p = 0.0009], DI [0.9 ± 0.4 mm2/mmHg vs 1.3 ± 0.6 mm2/mmHg, p = 0.001], and compliance [25.9 ± 12.8 mm3/mmHg vs 35.4 ± 13.4 mm3/mmHg, p = 0.01] were lower after the Hill procedure compared to Toupet. However, there was no difference in post-fundoplication HPZ between procedures [Hill: 2.9 ± 0.4 cm, Toupet: 3.1 ± 0.6 cm, p = 0.15]. Follow-up showed no significant differences in GERD-HRQL scores, overall dysphagia scores or atypical symptoms between groups (p > 0.05).

CONCLUSION

The Hill procedure is as effective to the Toupet fundoplication in surgically treating gastroesophageal reflux disease (GERD) despite the lower CSA, DI, and compliance after the Hill procedure. Both procedures led to DI < 2 mm2/mmHg with no significant differences in dysphagia reporting (12-24) months after the procedure. Further studies to elucidate a cutoff value for DI for postoperative dysphagia development are still warranted.

Improvement in swallowing safety after injection laryngoplasty in patients with unilateral vocal paralysis complicated with aspiration

BACKGROUND

The benefit of injection laryngoplasty (IL) on voice for unilateral vocal fold paralysis (UVFP) is supported increasingly in literatures, yet less is known for swallowing. Also, prevalence of patient-reported dysphagia is substantially higher than instrumental studies. This prospective study focused on swallowing outcomes, with predetermined flexible endoscopic evaluation of swallowing (FEES) protocol that simulates daily life situation.

METHODS

Adult patients with UVFP and aspiration receiving IL were recruited. Voice outcome measurements, as well as swallowing outcomes including Eating Assessment Tool (EAT-10) and FEES, which challenged patients with different fluid volumes: 10 mL, 20 mL, and 90 mL cup sipping were evaluated.

RESULTS

Significant improvements were demonstrated in all voice outcomes. Significant changes were also presented inEAT-10 (P < 0.01). Pre-operatively, penetration-aspiration scale (PAS) was 1.5 ± 1.3, 1.9 ± 1.7 and 2.3 ± 1.8 for 10 mL, 20 mL and 90 mL serial sipping, and improved to 1.1 ± 0.3, 1.1 ± 0.4 and 1.4 ± 0.7 post-operatively (P < 0.01). Safe swallowing (PAS ≤ 2) was achieved in all, except for one patient, who presented with a post-injection PAS of 4 (material enters the airway, contacts the vocal folds, and is ejected from the airway) on 90 mL cup sipping, whose pre-injection PAS was 7 (residue in trachea).

CONCLUSION

Maintaining swallowing function suitable for social environment is important. Our results demonstrated the feasibility of the predetermined FEES protocol, and positive effects of IL on both voice and swallowing outcomes.

The efficacy of post-operative drains for anterior cervical discectomy and fusion: a systematic review and meta-analysis

BACKGROUND

Controversy remains with the use of post-operative subfascial drains for anterior cervical discectomy and fusion, with limited guidelines and a paucity of conclusive evidence. Thus, the aim of this meta-analysis was to analyse and collate an evidence summary to determine the efficacy of such drains.

METHODS

A systematic search of Medline (2002-2022.11), PubMed (2003-2022.11), Scopus (2002-2022.11), Cochrane Library (2015-2022.11) databases and reference lists of articles was conducted as per Cochrane systematic reviews standards. All relevant RCTs and NRCTs were included in this study. Data was extracted in a standardised form and analysed with RevMan version 5.4.1. Bias was assessed with RoB2 tool for RCTs and ROBINS-E tool for NRCTs.

RESULTS

Two RCTs (136 patients) and five NRCTs (7563 patients) were included. These had a moderate to high risk of bias, except for one very high-risk article. Meta-analysis results showed no significant differences for post-operative haematoma (P = 0.31), surgical site infection (P = 0.84), take back to theatre (P = 0.27), length of stay (P = 0.34), and estimated blood loss (P = 0.09). Dysphagia (P = 0.002) and median operative time (P = 0.02) were significantly increased in the drain cohort.

CONCLUSION

The low quality of available data in the included studies is insufficient to estimate the effect of post-operative drains for elective spondylotic ACDF. The findings suggest that if the decision to leave a drain in is left to the surgeon, then there is no difference in the rates of POH, SSI, LOS, or take back to the theatre. The significant association of dysphagia and increased operative time with drains, and the non-significant trend towards increased EBL with drains, must be considered in the context in which procedures may influence the decision to place drains. The results could not be stratified by various confounders that affect the decision-making process, including the number of levels operated. Due to the decreased quality and amount of evidence available, large-scale RCTs that adequately account for confounders should be performed.

Outcomes of Surgical Repair of Aberrant Subclavian Arteries in Adults

BACKGROUND

Symptoms, imaging characteristics, and early and midterm surgical outcomes for aberrant subclavian arteries (ASCA) are not well defined in the adult population.

METHODS

A single-institution retrospective review was conducted of adults undergoing surgical repair of ASCA and descending aorta origin/Kommerell diverticulum (KD) from January 1, 2002, to December 31, 2021. Symptom improvement and differences in imaging characteristics between anatomic groups and the number of symptoms were assessed.

RESULTS

Mean age was 46 ± 17 years. There were 23 of 37 left aortic arches with right ASCA (62%) and 14 of 37 right aortic arches with left ASCA (38%). Of these, 31 of 37 (84%) were symptomatic, and 19 of 37 (51%) had KD size/growth meeting criteria for surgical repair. KD aortic origin diameter was larger in more symptomatic patients: 20.60 mm (interquartile range [IQR], 16.42-30.68 mm) in patients with ≥3 symptoms vs 22.05 mm (IQR, 17.52-24.21 mm) for 2 symptoms vs 13.72 mm (IQR, 12.70-15.95 mm) for 1 symptom (P = .018). Aortic replacement was required in 22 of 37 (59%). There were no early deaths. Complications occurred in 11 of 37 (30%): vocal cord dysfunction (4 of 37 [11%]), chylothorax (3 of 37 [8%]), Horner syndrome (2 of 37 [5%]), spinal deficit (2 of 37 [5%]), stroke (1 of 37 [3%]), and temporary dialysis requirement (1 of 37 [3%]). Over a median follow-up of 2.3 years (IQR, 0.8-3.9 years), there was 1 endovascular reintervention and no reoperations. Dysphagia and shortness of breath resolved in 92% and 89%, respectively, whereas gastroesophageal reflux persisted in 47%.

CONCLUSIONS

The KD aortic origin diameter correlates with the number of symptoms, and surgical repair of ASCA and descending aorta origin/KD effectively relieves symptoms, with low rates of reintervention. Given the operative complexity, surgical repair should be performed in patients meeting size criteria or with significant dysphagia or shortness of breath symptoms.

Second free jejunum transfer after flap loss does not affect oral intake: A retrospective case-control study

PURPOSE

Free jejunum transfer is one of the standard procedures for restoring oral intake after total pharyngo-laryngo-esophagectomy. Flap loss leading to a second free jejunum transfer rarely occurs. This study investigated the impact of a second free jejunum transfer on post-operative oral intake.

METHODS

A retrospective review was conducted on patients who underwent a first free jejunum transfer between July 1998 and December 2019. A total of 367 patients were included in the study. Among them, 17 patients who underwent a second free jejunum transfer because necrosis constituted the second free jejunum transfer group, whereas 350 patients who did not require a second free jejunum transfer formed the first free jejunum transfer group. The incidence of dysphagia requiring tube feeding and post-operative complications was compared between the two groups. Moreover, risk factors for dysphagia and complications were estimated.

RESULTS

There were no statistically significant differences in the incidence of dysphagia post-operation between the two groups. A second free jejunum transfer was a statistically significant factor for complications at 2- and 6-months post-operation; however, there were no significant differences in complication rates at the 12-month follow-up. Furthermore, there were no significant differences in the incidence of severe complications between the two groups.

CONCLUSION

Although a second free jejunum transfer increases early complications, it is not associated with major complications and does not negatively impact oral intake. These findings support the conclusion that free jejunum transfer is safe and helps maintain post-operative quality of life.

[Dysphagia as the main symptom in anterior cervical spine osteophytes (Forestier disease and cervical spondylosis deformans). Case reports and literature review]

Anterior cervical osteophytes are a fairly common X-ray finding in people over 50 years old. Incidence of dysphagia in patients with anterior osteophytes varies from 1% in those aged 40-60 years to 10.6% in patients over 60 years old. The most common causes of anterior cervical hyperosteophytosis causing dysphagia are cervical spondylosis deformans and Forestier disease. We present 2 clinical cases of spondylogenic dysphagia in cervical spondylosis deformans and Forestier disease. The review is devoted to the causes and diagnostic methods for dysphagia caused by anterior cervical osteophytes, as well as surgical options for this pathology.

CONCLUSION

Microsurgical resection of anterior osteophytes is an effective method for dysphagia after ineffective therapy for 3 months. Microsurgical osteophytectomy provides stable regression of dysphagia with low recurrence rate.

Success rates of fixation techniques on prevention of esophageal stent migration: a systematic review and meta-analysis

BACKGROUND

 Esophageal stenting is an important intervention for managing malignant and benign dysphagia, with stent migration representing a common drawback. This systematic review with meta-analysis aimed to assess the benefit of stent fixation over nonfixation.

METHODS

 A systematic search was performed in MEDLINE, Cochrane, Scopus, and ClinicalTrials.gov databases until January 2023 for comparative studies evaluating the migration rates of esophageal stents with versus without (control) fixation. The primary outcome was migration rate. Secondary outcomes included adverse event rate. A subgroup analysis stratified the results based on different fixation techniques: suturing, over-the-scope (OTS) clipping, and through-the-scope (TTS) clipping. Meta-analysis was based on a random effects model and the results were reported as odds ratios (ORs) with 95 %CIs.

RESULTS

 10 studies (1014 patients) were included. The rate of stent migration was significantly lower after fixation (OR 0.20, 95 %CI 0.11-0.37; I2  = 59 %, P = 0.01). The adverse event rate was similar between fixation and control groups (OR 0.65, 95 %CI 0.28-1.52; I2  = 55 %, P = 0.06). In the subgroup analysis, all fixation techniques remained superior to nonfixation of stents (suturing OR 0.23, 95 %CI 0.10-0.53; OTS clips OR 0.31, 95 %CI 0.17-0.58; TTS clips OR 0.10, 95 %CI 0.03-0.38); however, only the OTS and TTS clip groups achieved nonsignificant heterogeneity (I2  = 0 %, P = 0.67 and P = 0.73, respectively). No difference between techniques was recorded for migration rates.

CONCLUSION

 Esophageal stent fixation was associated with significantly lower migration rates compared with nonfixation of stents, regardless of fixation technique and stenting indication.

Indication as a predictor for outcomes in anterior cervical discectomy and fusion: The impact of myelopathy on disposition

BACKGROUND

While the indication for Anterior Cervical Discectomy and Fusion (ACDF) may influence the expected postoperative course, there is limited data comparing how length of stay (LOS) and disposition for patients with myelopathy differ from those with radiculopathy. This study aimed to compare LOS and discharge disposition, in patients undergoing ACDF for cervical radiculopathy versus those for myelopathy.

METHODS

A retrospective review of all adult ACDF cases between 2013 and 2019 was conducted analyzing sex, age, race, comorbidities, level of surgery, myelopathy measures when applicable, complications, dysphagia, hospital LOS, and discharge disposition.

RESULTS

A total of 157 patients were included in the study with 73 patients undergoing an ACDF for radiculopathy and 84 for myelopathy. Univariate analysis determined older age (p < 0.01), male sex (p = 0.03), presence of CKD (p < 0.01) or COPD (p = 0.01), surgery at C3/4 level (p = 0.01), and indication (p < 0.01) as predictors for a discharge to either acute rehabilitation or a skilled nursing facility rather than to home. Multivariate logistic regression demonstrated age and indication as the only independent predictors of disposition, with home disposition being more likely with decreased age (OR 0.92, 95 % CI 0.86-0.98) and radiculopathy as the diagnosis (OR 6.72, 95 % CI 1.22- 37.02).

CONCLUSIONS

Myelopathic patients, as compared to those with radiculopathy at presentation, had significantly longer LOS, increased dysphagia, and were more often discharged to a facility. Understanding these two distinct populations as separate entities will streamline the pre and post-surgical care as the current DRG codes and ICD 10 PCS do not differentiate the expected post-operative course in patients undergoing ACDF for myelopathy versus radiculopathy.

A Novel Approach for the Treatment of Intractable Aspiration After Supracricoid Laryngectomy

OBJECTIVES

This manuscript aims to present a novel and successful intervention for intractable aspiration following a supracricoid laryngectomy (SCL) that may avoid the need for total laryngectomy in patients experiencing intractable aspiration after SCL.

STUDY DESIGN

This report describes a novel approach to treat intractable aspiration and feeding tube-dependency due to an incomplete posterior apposition of the laryngeal surface of the epiglottis to the arytenoids after a SCL in a 67-year-old man.

METHODS

The right and left aryepiglottic folds and the median glossoepiglottic fold were denuded using a CO2 laser. Then, an arytenoepiglottopexy was completed by placing 4-0 Vicryl between the lateral aspect of the epiglottis and arytenoids; thus, approximating these structures.

RESULTS

Two weeks after surgery, fiberoptic endoscopic evaluation of swallowing demonstrated improved closure of the larynx upon swallowing with great upgrading in the Penetration-Aspiration scale (PAS). PAS improved from a 6 to 2, corresponding to, transient penetration for moderately thick liquids and puree solids. He also demonstrated improved secretion management and airway protection. Following a 4-week course of intensive dysphagia therapy, a modified barium swallow revealed a significant improvement in airway protection, with a PAS score of 1 (no airway invasion).

CONCLUSIONS

Chronic aspiration is a life-threatening condition that can severely reduce patients' quality of life. Despite the use of current therapeutic approaches, a subset of patients will remain plagued by persistent symptoms. We introduce an innovative, simple, and quick endoscopic technique that offers benefit in controlling aspiration after SCL.

Acute cricopharyngeal achalasia after general anesthesia in myotonic dystrophy: A case report

RATIONALE

Myotonic dystrophy type 1 (DM-1) is a progressive multisystem genetic disorder that causes myotonia and both distal limb and facial/neck muscle weakness by expanding the CTG repeats of the DMPK gene in chromosome 19q13.3. General anesthesia is indicated in DM-1 patients owing to their sensitivity to anesthetic drugs such as opioids, hypnotics, and neuromuscular blocking agents.

PATIENT CONCERNS

A 48-year-old male patient underwent a laparoscopic cholecystectomy for gallstones under general anesthesia. He experienced sudden cardiac arrest and respiratory failure the day after surgery. After a thorough review of past medical history, we recognized that 15 years prior, he had been diagnosed with classic type DM-1, but the diagnosis was not self-reported before general anesthesia. Symptoms of severe dysphagia developed subsequently. In a videofluoroscopic swallowing study (VFSS), we observed abrupt aggravation of myotonic dysphagia after general anesthesia. VFSS revealed cricopharyngeal opening dysfunction, with a remaining large residue in the pyriform sinus, resulting in a severe cricopharyngeal achalasia pattern.

DIAGNOSIS

Acute cricopharyngeal achalasia after general anesthesia.

INTERVENTION AND OUTCOME

The patient underwent a dysphagia rehabilitation program that included cricopharyngeal opening exercises and functional electrical stimulation. However, no significant improvement was observed in the cricopharyngeal achalasia in a 3-month follow-up VFSS.

LESSONS

Low body temperature and anesthetic medications such as opioids and hypnotic agents can induce myotonia in the cricopharyngeal muscle.

Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA): Influences on the Voice Changes and Swallowing Function Disorders

OBJECTIVE

The aim of this study was to evaluate the influence of transoral endoscopic thyroidectomy vestibular approach (TOETVA) on voice changes and swallowing function disorders.

MATERIALS AND METHODS

We retrospectively reviewed 215 patients who underwent thyroid surgery with TOETVA (105 cases, endoscopic group) and open approach (110 cases, open group). Major outcomes, the changes in voice and swallowing function in the 2 groups of patients before and after surgery were analyzed by using both subjective and objective evaluation indexes. Subjective evaluation indexes included the Voice Handicap Index, voice GRBAS (Grade, Roughness, Breathiness, Asthenia, Strain) classification, and swallowing impairment score; the objective indicators included the fundamental frequency (F0), fundamental frequency perturbation (jitter), amplitude perturbation (shimmer), and maximum phonation time.

RESULTS

In terms of subjective evaluation indexes, there were no significant differences (all P> 0.05) between the groups regarding Voice Handicap Index (1 and 3 mo after surgery) and GRBAS (1 and 3 mo after surgery). The incidence rates of swallowing disorder in the endoscopic group were higher than that in the open group according to the outcomes of swallowing impairment score at 1 and 3 months after surgery (both P< 0.05). In addition, no significant changes in terms of jitter, shimmer, and maximum phonation time in both groups of patients at 1 and 3 months after surgery compared with their preoperative values (all P> 0.05).

CONCLUSIONS

Voice and swallowing disorders may occur in some patients, either TOETVA or open thyroid surgery, which in most cases will recover within 3 months after surgery. The time to swallowing function recovery is relatively prolonged in patients following TOETVA, which may be probably associated with neck adhesion and fixation after the operation.

Swallowing evaluation in patients who underwent Partial CO2 LASER Epiglottectomy for Sleep Apnea treatment

OBJECTIVE

To evaluate swallowing in patients who underwent CO2 LASER Partial Epiglottectomy (CO2-LPE) for Obstructive Sleep Apnea Syndrome and to assess the risk of aspiration with this technique.

MATERIAL & METHODS

Chart review of adult patients who underwent CO2-LPE between 2016 and 2020, in a secondary care hospital. Patients underwent surgery for OSAS, in accordance to Drug Induced Sleep Endoscopy findings and an objective swallowing evaluation was done at least 6 months after surgery. Eating Assessment Tool (EAT-10) questionnaire was applied and Volume-Viscosity Swallow Test (V-VST) and Fiberoptic Endoscopic Evaluation of Swallowing (FEES) were performed. Dysphagia was classified according to Dysphagia Outcome Severity Scale (DOSS).

RESULTS

Eight patients were included in the study. The mean time between surgery and the swallowing evaluation was 50 (±13,2) months. Only 3 patients presented ≥ 3 points on EAT-10 questionnaire. Two patients presented signs of decreased efficacy of swallowing (piecemeal deglutition) but none had a decrease in safety, according to V-VST. Although 50% of the patients presented some pharyngeal residue on FEES, it was classified as trace to mild in most of the cases. No evidence of penetration or aspiration was identified (DOSS ≥ 6 in all patients).

CONCLUSION

The CO2-LPE is a potential treatment for OSAS patients with epiglottic collapse and no evidence of swallowing safety compromise was found.

Laparoscopic Nissen Versus Toupet Fundoplication for Short- and Long-Term Treatment of Gastroesophageal Reflux Disease: A Meta-Analysis and Systematic Review

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is the most common standard technique worldwidely for Gastroesophageal reflux disease (GERD). Another type of fundoplication, laparoscopic Toupet fundoplication (LTF), intends to reduce incidence of postoperative complications. A systematic review and meta-analysis are required on short- and long-term outcomes based on randomized controlled trials (RCTs) between LNF and LTF.

METHODS

We searched databases including PubMed, Cochrane, Embase, and Web of Knowledge for RCTs comparing LNF and LTF. Outcomes included postoperative reflux recurrence, postoperative heartburn, dysphagia and postoperative chest pain, inability to belch, gas bloating, satisfaction with intervention, postoperative esophagitis, postoperative DeMeester scores, operating time (min), in-hospital complications, postoperative use of proton pump inhibitors, reoperation rate, postoperative lower oesophageal sphincter (LOS) pressure (mmHg). We assessed data using risk ratios and weighted mean differences in meta-analyses.

RESULTS

Eight eligible RCTs comparing LNF (n = 605) and LTF (n = 607) were identified. There were no significant differences between the LNF and LTF in terms of postoperative reflux recurrence, postoperative heartburn, postoperative chest pain, satisfaction with intervention, reoperation rate in short and long term, in-hospital complications, esophagitis in short term, and gas bloating, postoperative DeMeester scores, postoperative use of proton pump inhibitors, reoperation rate in long term. LTF had lower LOS pressure (mmHg), fewer postoperative dysphagia and inability to belch in short and long term and gas bloating in short term compared to LNF.

CONCLUSION

LTF were equally effective at controlling reflux symptoms and improving the quality of life, but with lower rate of complications compared to LNF. We concluded that LTF surgical treatment was superior for over 16 years old patients with typical symptoms of GERD and without upper abdominal surgical history upon high-level evidence of evidence-based medicine.

Combined laryngeal framework surgery and cricopharyngeal muscle-origin transection: a novel effective surgery for dysphagia with pharyngolaryngeal palsy and cricopharyngeal dysfunction under local anesthesia

BACKGROUND

Cricopharyngeal myotomy and laryngeal framework surgery can improve swallowing function in patients with severe dysphagia. We developed a novel surgical technique for severe dysphagia associated with pharyngolaryngeal paralysis and cricopharyngeal dysfunction, performed under local anesthesia, and investigated its effectiveness.

METHODS

We included nine patients who underwent cricopharyngeal muscle-origin transection with laryngeal framework surgery through a horizontal skin incision under local anesthesia.

CONCLUSIONS

All patients demonstrated significant improvement in the Food Intake LEVEL Scale without complications. Thus, this surgical technique may serve as a useful and less invasive treatment option for patients with severe dysphagia.

Current opinion in otolaryngology and head and neck surgery: the role of the otolaryngologist in the management of pediatric dysphagia

PURPOSE OF REVIEW

Dysphagia affects at least 1% of the pediatric population. This prevalence further increases in patients who are born prematurely or who have underlying neuromuscular or cardiopulmonary disorders. A multidisciplinary team approach, including an Otolaryngologist, can help promote an expedited diagnosis and therapeutic regimen, ensuring that the patient receives adequate nutrition needed for growth and development.

RECENT FINDINGS

The development and growth of multidisciplinary aerodigestive clinics have improved outcomes in pediatric patients with dysphagia. If a structural concern is noted on examination, there remain a multitude of medical and surgical options to help improve patient outcomes and swallow. These treatment options are usually multimodality and specific interventions may be employed to target a specific and notable abnormality.

SUMMARY

Pediatric dysphagia is a complex concern. For the otolaryngologist, etiologies with surgical targets may include ankyloglossia, tonsillar hypertrophy, laryngomalacia, laryngo-esophageal cleft, vocal fold movement impairment, and cricopharyngeal achalasia. The development and formalization of a multidisciplinary approach has streamlined and broadened treatment options for these patients. An otolaryngologist is integral as part of the treatment team of these patients.

Per-oral endoscopic myotomy is a safe and effective treatment for Zenker's diverticulum: a retrospective multicenter study

Zenker per-oral endoscopic myotomy (ZPOEM) has become a promising technique for Zenker's diverticulum (ZD). The aim of this study was to add to the limited body of literature evaluating the safety and efficacy of ZPOEM. A prospectively maintained database was retrospectively reviewed to identify patients who underwent ZPOEM at two separate institutions between January 2020 and January 2022. Demographics, preoperative and postoperative clinical data, intraoperative data, adverse events, and length of stay were analyzed. A total of 40 patients (mean age 72.5 years, 62.5% male) were included. Average operative time was 54.7 minutes and average length of stay was 1.1 days. There were three adverse events, and only one was related to the technical aspects of the procedure. Patients showed improvement in the Functional Oral Intake Scale (FOIS) scores at 1 month (5 vs 7, p < 0.0001). The median FOIS scores remained 7 at both 6 and 12 months, although this improvement was not statistically significant at these time intervals (p = 0.46 and 0.37, respectively). Median dysphagia scores were decreased at 1 (2.5 vs 0, p < 0.0001), 6 (2.5 vs 0, p < 0.0001), and 12 months (2.5 vs 0, p = 0.016). The number of patients reporting ≥1 symptom was also decreased at 1 (40 vs 9, p < 0.0001) and 6 months (40 vs 1, p = 0.041). Although the number of patients reporting ≥1 symptom remained consistent at 12 months, this was not statistically significant (40 vs 1, p = 0.13). ZPOEM is a safe and highly effective treatment for the management of ZD. .

Laparoscopic Toupet fundoplication: a safe and effective anti-reflux option in lung transplant recipients

BACKGROUND

Fundoplication is known to improve allograft outcomes in lung transplant recipients by reducing retrograde aspiration secondary to gastroesophageal reflux disease, a modifiable risk factor for chronic allograft dysfunction. Laparoscopic Nissen fundoplication has historically been the anti-reflux procedure of choice, but the procedure is associated with discernable rates of postoperative dysphagia and gas-bloat syndrome. Laparoscopic Toupet fundoplication, an alternate anti-reflux surgery with lower rates of foregut complications in the general population, is the procedure of choice on our institution's lung transplant protocol. In this work, we evaluated the efficacy and safety of laparoscopic Toupet fundoplication in our lung transplant recipients.

METHODS

A prospective case series of 44 lung transplant recipients who underwent laparoscopic Toupet fundoplication by a single surgeon between September 2018 and November 2020 was performed. Preoperative and postoperative results from 24-h pH, esophageal manometry, gastric emptying, and pulmonary function studies were collected alongside severity of gastroesophageal reflux disease and other gastrointestinal symptoms.

RESULTS

Median DeMeester score decreased from 25.9 to 5.4 after fundoplication (p < 0.0001), while percentage of time pH < 4 decreased from 7 to 1.1% (p < 0.0001). The severity of heartburn and regurgitation were also reduced (p < 0.0001 and p = 0.0029 respectively). Overall, pulmonary function, esophageal motility, gastric emptying, severity of bloating, and dysphagia were not significantly different post-fundoplication than pre-fundoplication. Patients with decreasing rates of FEV1 pre-fundoplication saw improvement in their rate of change of FEV1 post-fundoplication (p = 0.011). Median follow-up was 32.2 months post-fundoplication.

CONCLUSIONS

Laparoscopic Toupet fundoplication provides objective pathologic acid reflux control and symptomatic gastroesophageal reflux improvement in lung transplant recipients while preserving lung function and foregut motility. Thus, laparoscopic Toupet fundoplication is a safe and effective antireflux surgery alternative in lung transplant recipients.

Evaluation of outcome measures for post-operative dysphagia after anterior cervical discectomy and fusion

PURPOSE

The goal is to conduct a review of the current literature to determine and evaluate the current classification metrics available for quantifying post-operative dysphagia.

METHODS

We surveyed the literature for the subjective and objective measures used to classify dysphagia, and further described and analyzed them in the context of post-operative dysphagia (PD) after anterior cervical spine surgery, with a focus on anterior cervical discectomy and fusion (ACDF). We searched PubMed from the years 2005-2021 using the terms "anterior cervical discectomy and fusion" and "dysphagia or postoperative dysphagia." We included papers that were meta-analyses, systemic reviews, prospective, or retrospective studies. Our selection was further consolidated via abstract and title screening. Ultimately, nineteen articles were included and had full-text reviews.

RESULTS

EAT-10 tool was shown to be more valid and reliable than the commonly used Bazaz grading system. HSS-DDI was found to have a high diagnostic accuracy in stratifying mild, moderate, and severe PD. A shortened 16-item version of the original 44-item SWAL-QOL was found to be statistically and clinically significant. When compared to PROMs, objective tests more accurately diagnose PD.

CONCLUSION

We found that the most valuable subjective tests were the EAT-10 and HSS-DI because they are quick, sensitive, and correlated strongly with the well-established measurements of PD. The MBS and FEES provided accurate measurements of the severity of PD, but they required more time and equipment than the surveys. In some patient populations, such as those with pre-surgical dysphagia, objective testing should always be done.

Association of the "Jet Phenomenon" with Positive Symptom Outcome Following Surgical Treatment of Cricopharyngeus Muscle Dysfunction

OBJECTIVES

Cricopharyngeus muscle dysfunction (CPMD) is a common cause for progressive dysphagia and can lead to dietary restriction, reduced nutrition, weight loss, and pneumonia. Controversy exists whether CPMD is best managed with primary surgical treatment of the cricopharyngeus muscle and who represents a good surgical candidate.

METHODS

Retrospective review of patients diagnosed with CPMD who underwent surgical treatment were evaluated through prospectively collected pre- and postoperative Eating Assessment Tool-10 (EAT-10) and Functional Oral Intake Scale (FOIS). Videofluoroscopic swallowing studies (VFSS) were reviewed for presence or absence of a high-pressure barium stream through the upper esophageal sphincter, termed the jet phenomenon (JP).

RESULTS

We identified 42 patients with CPMD who underwent surgical treatment and had serial Eating Assessment Tool (EAT-10) measures obtained pre- and postoperatively. Mean EAT-10 scores improved by 12.1 points (95%CI = 8.6-15.6), p < 0.0001. There was a significantly greater improvement among patients with JP (|∆EAT-10|= 17.0, 95%CI = 12.5-21.4) compared to those without (|∆EAT-10|= 6.2, 95%CI = 1.6-10.8), p = 0.0013. Patients with JP also showed improved FOIS score (p = 0.0023) while those without JP did not.

CONCLUSION

This study provides the initial report on the utility of JP as a VFSS feature that is strongly associated with improved outcomes following surgical treatment of CPMD. Further work determining the physiologic correlates responsible for JP will help clarify its predictive capabilities.

Predictive Factors for Dysphagia After Anterior Cervical Spine Surgery: A Prospective Multicenter Study

OBJECTIVE

To identify the incidence and predictors of postoperative dysphagia in patients who undergo anterior cervical spine surgery (ACSS) by utilizing the Eating Assessment Tool (EAT-10).

METHODS

A multicenter prospective study was undertaken at three hospitals to evaluate patients undergoing ACSS between January 2021 and January 2023. Included patients were aged 18-80 years and were undergoing primary or revision ACSS. Dysphagia was assessed using the validated EAT-10 questionnaire. Patients with dysphagia were included in the observation group, and those without dysphagia were included in the control group.

RESULTS

Of the 343 patients enrolled, 50 patients (14.6%) had EAT-10 scores of 3 or more at the 6-month follow-up. In the univariate analysis, patients with dysphagia at 7 days had a longer operative time, were current smokers, had involvement of vertebral bodies at C4 and above, and underwent intraoperative neurophysiological monitoring. Patients with dysphagia at 6 months had involvement of vertebral bodies at C4 and above and underwent intraoperative neurophysiological monitoring. In the multivariate analysis to determine associations with prolonged dysphagia, only the involvement of vertebral bodies at C4 and above (odds ratio 3.883, 95% confidence interval 1.847-8.165, P = 0.001) and intraoperative neurophysiological monitoring (odds ratio 0.273, 95% confidence interval 0.080-0.931, P = 0.038) remained significant.

CONCLUSIONS

Dysphagia is common after ACSS, affecting more than 67.5% of patients at 7 days postoperatively, but over time, the incidence of dysphagia gradually decreases. Involvement of the vertebral bodies at C4 and above is a risk factor for dysphagia after ACSS, and intraoperative neurophysiological monitoring is a protective factor.

A Novel Risk Model for Predicting Dysphagia after Tongue Reconstruction: A Retrospective Multicenter Study in Japan

BACKGROUND

There is no consensus on the postoperative outcomes of tongue reconstruction. Therefore, the authors developed a novel risk model for predicting dysphagia after tongue reconstruction.

METHODS

This retrospective study was conducted by the Oral Pharyngeal Esophageal Operation and Reconstruction Analytical, or OPERA, group across 31 cancer centers and university hospitals in Japan. A total of 532 patients [390 (73.3%) men and 142 (26.7%) women; median age at surgery, 60 years (range, 15 to 88 years)] who were diagnosed with oral tongue squamous cell carcinoma and underwent tongue reconstruction following glossectomy between 2009 and 2013 were included. Independent risk factors were identified using univariate regression analysis and converted to a binary format for multivariate analysis. An integer value was assigned to each risk factor to calculate a total score capable of quantifying the risk of feeding tube dependence.

RESULTS

Overall, 54 patients (10.2%) required a feeding tube at the time of evaluation. Predictive factors for feeding tube dependence were advanced age, lower American Society of Anesthesiologists physical status, low body mass index, lower serum albumin, comorbid hypertension and diabetes, extended tongue defect, resection beyond the tongue, laryngeal suspension, postoperative radiation therapy, and no functional teeth. In multivariate logistic regression analysis, age greater than or equal to 58.5 years, postoperative radiation therapy, wider tongue defect, and body mass index less than 21.27 kg/m 2 earned 6, 4, 3, and 2 points, respectively, for a maximum total score of 15.

CONCLUSION

The authors' risk model provides a mathematical tool for estimating the individual risk of postoperative feeding tube dependence before tongue reconstruction.

The robot can break bars with the best of them: a novel approach to treating cricopharyngeal bars with myotomy

INTRODUCTION

Failure of the cricopharyngeus to relax results in oropharyngeal dysphagia, which over time results in hypertrophy and increased risk for aspiration. Open myotomy is one definitive treatment option, however there are several drawbacks attributable to the long neck incision, ± drain placement, and invasiveness of the procedure. We aim to share our experience using the DaVinci robotic platform to perform a minimally invasive cricopharyngeal myotomy, which has never been described before in the literature.

METHODS

All robotic cricopharyngeal myotomies performed in adult patients by a single surgeon from 2021 to 2022 were retrospectively reviewed. No patients were excluded. Outcomes of interest included length of procedure, time to diet resumption, hospital length of stay, complications, symptom improvement at follow-up, and symptom recurrence.

RESULTS

Eight robotic cricopharyngeal myotomies were performed. The median age was 65 years old (62-91) and mostly female (n = 5, 56%) with a median BMI of 28.9 kg/m2 (21.7-39.5). The median procedure length was 113 min (94-141) and there were no intraoperative complications. All patients underwent a post-procedural esophagram with no leaks were identified. All patients were started on clear liquids in recovery and transitioned to full liquids prior to discharge. All but one patient was subsequently discharged home on the same day as procedure. All patients had routine 2-week post-operative follow-up in addition to phone follow-up at a later date (6-11 months post-operative). All patients reported resolution of symptoms. There were no complications or readmissions. No instances of recurrence were reported. On cost analysis, the minimally invasive robotic approach allows for an outpatient procedure with similar cost to an open approach with a one-night stay.

CONCLUSION

Our experience with the novel technique of minimally invasive robotic cricopharyngeal myotomy for cricopharyngeal bars with cervical dysphagia is safe, efficacious, less invasive, and cost saving, with excellent patient outcomes.

Lap. Nissen fundoplication leads to better respiratory symptom control than Toupet in the long term of 20 years

INTRODUCTION

Having performed anti-reflux surgery for thirty years, it was important to reexamine our patients in the long term to enlarge the body of evidence concerning classical and extraesophageal symptoms that are differently controlled by Nissen or Toupet fundoplication.

OBJECTIVES

We report a cohort of 155 GERD patients who underwent fundoplication within a tailored approach between 1994 and 2000. Changes in the perioperative functional outcome, GERD symptoms, and quality of life are being analyzed 10 and 20 years after the operation.

RESULTS

The operation resulted in a superior quality of life compared to a patient cohort treated with PPI therapy. We found that both surgical methods (laparoscopic Nissen fundoplication and laparoscopic Toupet fundoplication) cure classical symptoms equally (heartburn, regurgitation, and dysphagia). GERD patients receiving a Toupet fundoplication seem more likely to suffer from extraesophageal GERD symptoms 10 and 20 years after surgery than patients with a Nissen fundoplication. On the other hand, some patients with Nissen fundoplication report dysphagia even 10 and 20 years after surgery.

CONCLUSION

Both the laparoscopic Nissen and Toupet fundoplications provide excellent symptom control in the long term. Moreover, the Nissen fundoplication seems to be superior in controlling extraesophageal reflux symptoms, but at the expense of dysphagia. In summary, tailoring the operation based on symptoms seems advantageous.

International Multi-Institutional Experience with Presentation and Management of Aortic Arch Laterality in Aberrant Subclavian Artery and Kommerell's Diverticulum

BACKGROUND

Aberrant subclavian artery (ASA) with or without Kommerell's diverticulum (KD) is a rare anatomic aortic arch anomaly that can cause dysphagia and/or life-threatening rupture. The objective of this study is to compare outcomes of ASA/KD repair in patients with a left versus right aortic arch.

METHODS

Using the Vascular Low Frequency Disease Consortium methodology, a retrospective review was performed of patients ≥18 years old with surgical treatment of ASA/KD from 2000 to 2020 at 20 institutions.

RESULTS

288 patients with ASA with or without KD were identified; 222 left-sided aortic arch (LAA), and 66 right-sided aortic arch (RAA). Mean age at repair was younger in LAA 54 vs. 58 years (P = 0.06). Patients in RAA were more likely to undergo repair due to symptoms (72.7% vs. 55.9%, P = 0.01), and more likely to present with dysphagia (57.6% vs. 39.1%, P < 0.01). The hybrid open/endovascular approach was the most common repair type in both groups. Rates of intraoperative complications, death within 30 days, return to the operating room, symptom relief and endoleaks were not significantly different. For patients with symptom status follow-up data, in LAA, 61.7% had complete relief, 34.0% had partial relief and 4.3% had no change. In RAA, 60.7% had complete relief, 34.4% had partial relief and 4.9% had no change.

CONCLUSIONS

In patients with ASA/KD, RAA patients were less common than LAA, presented more frequently with dysphagia, had symptoms as an indication for intervention, and underwent treatment at a younger age. Open, endovascular and hybrid repair approaches appear equally effective, regardless of arch laterality.

[Esophagectomy for Bronchogenic Cyst within the Esophageal Muscle Layer with Dysphagia:Report of a Case]

A 26-year-old man referred to our hospital because of dysphagia and a mediastinal tumor detected on chest computed tomography (CT). A contrast-enhanced CT revealed a 12 cm long cystic tumor along the right thoracic esophagus. An upper gastrointestinal endoscopy showed no abnormalities in the esophageal mucosa, and an unclear boundary between the tumor and the esophageal wall was observed by echography. In surgery, the tumor and the esophagus were in one lump, and esophagectomy was performed. On the fourth postoperative day, esophagogastric anastomosis was performed with poststernal reconstruction, and the patient was discharged home on the 38th postoperative day. Pathological examination revealed that the mass was a cystic lesion within the esophageal muscular layer, and the cyst wall was coated with airway-like multi-lineal hairy epithelium, which led to the diagnosis of a bronchogenic cyst. Even if the cyst is within the esophageal muscularis layer, bronchogenic cyst should be considered in the differential.

Need for frequent dilations after magnetic sphincter augmentation: an assessment of associated factors and outcomes

BACKGROUND

Dysphagia is the most common complaint after magnetic sphincter augmentation (MSA), with nearly one-third of patients requiring at least one dilation following MSA. A subset of patients require frequent dilations, but there is a paucity of data on the characteristics of this population. This study aimed to identify predictors of the need for frequent dilations within the first year after implant and to assess these patients' outcomes.

METHODS

This is a retrospective review of prospectively collected data of patients who underwent MSA over an 8-year period. Frequent dilations were defined as 2 or more dilations within 1 year of surgery. Patients completed baseline and 1-year postoperative GERD-HRQL questionnaires and objective physiology testing. Baseline demographic, clinical characteristics, and objective testing data were compared between patients who did and did not require frequent dilations.

RESULTS

A total of 697 (62.7% female) patients underwent MSA, with 62 (8.9%) patients requiring frequent dilation. At a mean (SD) of 12.3 (3.4) months follow-up, the frequent dilation group had higher median GERD-HRQL total scores (21.0 vs. 5.0, p < 0.001), PPI use (20.8% vs.10.1%, p = 0.023), dissatisfaction (46.7% vs. 11.6%, p < 0.001), and device removal (25.8% vs. 2.2%, p < 0.001) rates. Acid normalization was comparable (p = 0.997). Independent predictors of frequent dilation included preoperative odynophagia (OR 2.85; p = 0.001), IRP > 15 mmHg (OR 2.88; p = 0.006), and > 30% incomplete bolus clearance (OR 1.94; p = 0.004). At a mean (SD) of 15.7 (10.7) months, 28 (45.1%) patients underwent device removal after frequent dilation. Independent predictors of device removal after frequent dilation within 5 years of surgery were preoperative odynophagia (OR 7.18; p = 0.042), LES resting pressure > 45 mmHg (OR 28.5; p = 0.005), and ≥ 10% failed swallows (OR 23.5; p < 0.001).

CONCLUSIONS

The need for frequent dilations after MSA is a marker for poor symptom control, dissatisfaction, and device removal. Patients with preoperative odynophagia, high LES pressures, and poor esophageal motility should be counseled of their risk for these poor outcomes.

Videofluoroscopic Measures of Swallowing After Partial Epiglottidectomy for Dysphagia

OBJECTIVE

Partial epiglottidectomy has a role in improving dysphagia due to epiglottic obstruction. This study evaluates objective parameters of swallow function in patients who underwent partial epiglottidectomy.

STUDY DESIGN

Retrospective study design.

SETTING

Tertiary Care University Academic Medical Center.

METHODS

A review was performed of patients who underwent CO2 laser partial epiglottidectomy for the treatment of dysphagia at a single tertiary care academic center over a 4-year period. Objective swallowing parameters were evaluated from pre- and postoperative modified barium swallow studies using SwallowTail Advanced Measurement software using blinded reviewers. The postswallow pharyngeal residue (bolus clearance ratio or BCR), spatiotemporal swallowing variables (oropharyngeal [OPT], hypopharyngeal [HPT], and total pharyngeal transit times [TPT]), and airway protection (Penetration-Aspiration Scale [PAS]) were analyzed. Student paired t test was used to determine significant changes in outcome parameters pre- and postsurgery.

RESULTS

Forty-three patients (age range 45-92 years, median 70) met the inclusion criteria. A majority (69.8%) had a history of external beam radiation therapy for head and neck cancer. BCR decreased significantly from a mean of 31.7% presurgery to 24.2% (p = .01) postsurgery. OPT, HPT, and TPT did not differ significantly postsurgery. The mean Eating Assessment Tool-10 score improved from 25.1 to 20.2 after treatment (p = .03). PAS score improved by 15.4% and remained stable at 66.2% after surgery.

CONCLUSION

Partial epiglottidectomy improves pharyngeal bolus clearance in properly selected patients with dysphagia due to epiglottic obstruction. Patients demonstrated stable swallow function with the benefit of reduced postswallow residue following surgical intervention.

Effects of Different Levels of Surgical Separation on Neck Bulge and Swallowing Disorders during Endoscopic Thyroidectomy

OBJECTIVE

Our study aims to compare the effects of different levels of access on postoperative neck bulge and swallowing disorder and provide a better level for endoscopic thyroidectomy.

MATERIALS AND METHODS

The patients were selected retrospectively between March 2021 to September 2021 by the Department of Thyroid Surgery, Third Affiliated Hospital of Zunyi Medical University. They were divided into two groups according to the level of the free flap during surgery: group A (the superficial cervical fascial level) and group B (the superficial deep cervical fascial level). Age, sex, body mass index, diameter of the primary lesion, postoperative neck bulge, and swallowing disorders and other complications were compared between the two groups.

RESULTS

A total of 40 patients who underwent endoscopic unilateral lobectomy plus central region lymph node dissection were enrolled in our study. Twenty in group A and 20 in group B. The age, gender, body mass index, diameter, and the proportion of benign and malignant primary lesions were not significantly different between the two groups ( P >0.05), and there was also no difference in thyroid function between the two groups ( P >0.05). No significant differences were observed in terms of bleeding and operation time during the operation ( P >0.05). There were also no statistical differences in terms of recurrent laryngeal nerve injury or hypoparathyroidism ( P >0.05). However, patients in group B were superior to those in group A in the occurrence of neck bulge and swallowing disorders ( P <0.05). These symptoms were most evident one month after surgery. Six months after the operation, only 4 patients in group B still complained of neck "swelling" and uncomfortable straining which did not resolve until 1 year after the operation. No statistical significance between long-term results and complication rates could be observed in either group.

CONCLUSION

In endoscopic thyroidectomy, the superficial cervical fascial level may be a better option for reducing postoperative neck bulge and swallowing disorders, which needs further validation by conducting a large sample study.

The Role of Biologic Mesh and Fundoplication in the Surgical Management of Hiatal Hernias: A Multicenter Evaluation

INTRODUCTION

Hiatal hernia repair is associated with substantial recurrence of both hiatal hernia and symptoms of gastroesophageal reflux (GER). While small randomized controlled trials demonstrate limited differences in outcomes with use of mesh or fundoplication type, uncertainty remains.

METHODS

A multicenter, retrospective review of patients undergoing surgical treatment of hiatal hernias between 2015 and 2020 was performed. Patients with mesh and with suture-only repair were compared, and partial versus complete fundoplication was compared. Primary outcomes were hernia recurrence and occurrence of postoperative GER symptoms and dysphagia. Multivariable regression was performed to assess the effect of each intervention on clinical outcomes.

RESULTS

A total of 453 patients from four sites were followed for a median (IQR) of 17 (13) months. On multivariate analysis, mesh had no impact on hernia recurrence (odds ratio 0.993, 95% CI: 0.53-1.87, p = 0.982), and fundoplication type did not impact recurrence of postoperative GER symptoms (complete: odds ratio 0.607, 95% CI: 0.33-1.12, p = 0.112) or dysphagia (complete: odds ratio 1.17, 95% CI: 0.56-2.43, p = 0.677).

CONCLUSION

During hiatal hernia repair, mesh and fundoplication type do not appear to have substantial impact on GER symptoms, dysphagia, or hernia recurrence. This multicenter study provides real-world evidence to support the findings of small RCTs.

[Dysphagia lusoria treated by surgery]

Aberrant right subclavian artery, also called arteria lusoria, is the most common congenital anomaly of the aortic arch (prevalence 0,5-1.8 %). Patients with trisomy 21 have a higher prevalence (35 %). It takes its origin from the aortic arch after the three others supra-aortic trunks. It may be associated with other cardiovascular anomalies. In more than 80 % of cases, the aberrant artery is positioned behind the oesophagus. It is often asymptomatic. Sometimes it is associated with symptoms after the age of 40 years old, more often among women: dysphagia (dysphagia lusoria), dyspnoea or cough. Diagnosis is made by computed tomography or magnetic resonance imaging. When it is symptomatic, a barium contrast radiography of the oesophagus is indicated. Surgical treatment by transposition of the aberrant vessel is performed only for symptomatic patients. We report the case of a 50-year-old woman with dysphagia lusoria treated by transposition of the aberrant right subclavian artery into the right common carotid through a cervical approach.

Outcomes of Heller Myotomy for Esophageal Achalasia: Lessons From a 48-Year Prospective Experience With 4 Different Techniques

OBJECTIVE

To provide information on long-term outcomes of Heller myotomy for esophageal achalasia with or without an antireflux fundoplication.

BACKGROUND

Since the adoption of the Heller myotomy, surgeons have modified the original technique in order to balance the cure of dysphagia and the consequent cardial incontinence.

METHODS

Totally, 470 patients underwent primary Heller myotomy between 1955 and 2020. A long abdominal myotomy (AM) was performed in 83 patients, the Ellis limited transthoracic myotomy (TM) in 30, the laparotomic Heller-Dor (L-HD) in 202, the videolaparoscopic Heller-Dor (VL-HD) in 155. The HD was performed under intraoperative manometric assessment. Starting on 1973 these patients underwent a prospective follow-up program of timed lifelong clinical, radiological, endoscopic evaluations.

RESULTS

Median follow-up time was 23.06 years [interquantile range (IQR): 15.04-32.06] for AM, 29.22 years (IQR: 13.46-40.17) for TM, 14.85 years (IQR: 11.05-21.56) for L-HD and 7.51 years (IQR: 3.25-9.60) for VL-HD. In AM, relapse of dysphagia occurred in 25/71 (35.21%), in TM in 11/30 (36.66%), in LH-D in 10/201 (4.97%), in VL-HD in 3/155 (1.93%). Erosive-ulcerative esophagitis was diagnosed for AM in 28.16%, for TM in 30%, for L-HD in 8.45%, for VL-HD in 2.58%. Overall, the outcome was satisfactory in 52.11% for AM, 41.9% for TM, 89.05% for L-HD, 96.12% for VL-HD.

CONCLUSIONS

The Dor fundoplication drastically reduces postmyotomy gastroesophageal reflux. The Heller-Dor operation is a competitive option for the cure of esophageal achalasia if this operation is performed according to the rules of surgical physiology learned by means of intraoperative manometry.

Efficacy and safety of laparoscopic Roux-en-Y gastric bypass in symptomatic patients following fundoplication failure: a meta-analysis

Revisional surgery may be required in a subset of patients who remain symptomatic despite undergoing laparoscopic fundoplication (LF) for gastroesophageal reflux disease (GERD). While revisional LF (RLF) is feasible in these patients, laparoscopic Roux-en-Y gastric bypass (LRYGB) may serve as an alternative, although its efficacy and safety remains unknown. This study aimed to determine the outcomes of LRYGB in symptomatic patients following failed LF for GERD. MEDLINE, EMBASE, and PubMed databases were systematically searched for studies reporting LRYGB outcomes in symptomatic adults despite undergoing LF for GERD. Postoperative symptom resolution, recurrence of heartburn and dysphagia, proton pump inhibitor (PPI) use, and body mass index (BMI) reduction were assessed to determine LRYGB efficacy. Postoperative morbidity and mortality were used to evaluate LRYGB safety. Twenty-two studies with 1523 patients were included. Pooled rates of symptom resolution, recurrence of heartburn and dysphagia, PPI use, morbidity, and mortality were 71.6% (95% CI 59.4-86.4), 15.6% (8.9-27.3), 20.7% (12.5-34.3), 29.6% (18.8-46.5), 39.5% (29.9-52.3), and 2.2% (1.2-4.0), respectively, following LRYGB. Similar rates were observed after RLF. However, BMI reduction was significantly greater after LRYGB compared with RLF (mean difference 6.1 kg/m², 4.8-7.4; p < 0.0001). LRYGB resulted in symptom relief in a majority of patients, and proved comparable to RLF regarding symptom recurrence and PPI use. Morbidity and mortality following LRYGB also did not differ from RLF. However, LRYGB was associated with considerably greater weight loss relative to RLF. Therefore, LRYGB is efficacious and an acceptable revisional procedure in symptomatic GERD patients who have previously undergone LF.

The Impact of Ineffective Esophageal Motility on Patients Undergoing Magnetic Sphincter Augmentation

OBJECTIVE

To evaluate and characterize outcomes of MSA in patients with IEM.

SUMMARY BACKGROUND DATA

MSA improves patients with gastroesophageal reflux and normal motility. However, many patients have IEM, which could impact the outcomes of MSA and discourage use.

METHODS

An international, multi-institutional case control study of IEM patients undergoing MSA matched to normal patients was performed. Primary outcomes were new onset dysphagia and need for postoperative interventions.

RESULTS

A total of 105 IEM patients underwent MSA with matching controls. At 1 year after MSA: GERD-Health Related Quality of Life was similar; DeMeester scores in IEM patients improved to 15.7 and 8.5 in controls ( P = 0.021); and normalization of the DeMeester score for IEM = 61.7% and controls = 73.1% ( P = 0.079).In IEM patients, 10/12 (83%) with preop dysphagia had resolution; 11/66 (17%) had new onset dysphagia and 55/66 (83%) never had dysphagia. Comparatively, in non-IEM patients, 22/24 (92%) had dysphagia resolve; 2/24 (8%) had persistent dysphagia; 7/69 (10%) had new onset dysphagia, and 62/69 (90%) never had dysphagia.Overall, 19 (18%) IEM patients were dilated after MSA, whereas 12 (11%) non-IEM patients underwent dilation ( P = 0.151). Nine (9%) patients in both groups had their device explanted.

CONCLUSIONS

Patients with IEM undergoing MSA demonstrate improved quality of life and reduction in acid exposure. Key differences in IEM patients include lower rates of objective GERD resolution, lower resolution of existing dysphagia, higher rates of new onset dysphagia and need for dilation. GERD patients with IEM should be counselled about these possibilities.

Relationship between dysphagia and surgical treatment for supraglottic laryngeal carcinoma: A meta-analysis

OBJECTIVE

To systematically evaluate differences in swallowing disorder-related manifestations in patients with supraglottic laryngeal cancer, who underwent traditional open partial horizontal laryngectomy (OPHL) and endoscopic supraglottic laryngectomy (ESL).

METHODS

A systematic review of the literature and a meta-analysis were performed. The CNKI, Wan Fang, PubMed, EMBASE, Cochrane Library, Web of Science, and Clinical Trials databases for clinical studies data sources were investigated. The efficiency of recovery, postoperative swallowing function, and complications related to dysphagia were investigated to compare the effects of surgical procedures.

RESULTS

The meta-analysis included 8 studies with 281 patients. ESL surgery played a positive role in the recovery of patients. Preservation of the anterior epiglottic space, ventricular band, and arytenoid cartilage without destroying the external framework of the larynx can effectively reduce the risk of aspiration pneumonia in patients.

CONCLUSIONS

ESL has advantages in postoperative recovery and retention of swallowing function in patients with supraglottic laryngeal cancer.

Efficacy of laparoscopic Toupet fundoplication compared to endoscopic and surgical procedures for GERD treatment: a randomized trials network meta-analysis

PURPOSE

We aim to review and quantitatively compare laparoscopic Toupet fundoplication (LTF), Nissen fundoplication (LNF), anterior partial fundoplication (APF), magnetic augmentation sphincter (MSA), radiofrequency ablation (RFA), transoral incisionless fundoplication (TIF), proton pump inhibitor (PPI), and placebo for the treatment of GERD. A number of meta-analyses compared the efficacy of surgical and endoscopic procedures for recalcitrant GERD, but considerable debate on the effectiveness of operative strategies remains.

METHODS

A systematic review of MEDLINE databases, EMBASE, and Web of Science for randomized controlled trials (RCTs) comparing the aforementioned surgical and endoscopic GERD treatments was performed. Risk ratio and weighted mean difference were used as pooled effect size measures, whereas 95% credible intervals (CrI) were used to assess relative inference.

RESULTS

Thirty-three RCTs were included. Surgical and endoscopic treatments have similar RR for heartburn, regurgitation, bloating. LTF has a lower RR of post-operative dysphagia when compared to APF (RR 3.3; Crl 1.4-7.1) and LNF (RR 2.5; Crl 1.3-4.4). The pooled network meta-analysis did not observe any significant improvement regarding LES pressure and pH < from baseline. LTF, APF, LNF, MSA, RFA, and TIF had have a similar post-operative PPI discontinuation rate.

CONCLUSION

LTF has a lower rate of post-operative dysphagia when compared to APF and LNF. The pre-post effects, such as GERD-HQRL, LES pressure, and pH <4, should be avoided in meta-analyses because results may be biased. Last, a consensus about the evaluation of GERD treatments' efficacy and their outcomes is needed.

[Not Available]

This is a classic case report of a rare giant fibrovascular polyp (GFP) of the oesophagus in a 50-year-old male patient, who two years prior had regurgitated the polyp and swallowed it again. He only sought medical professionals after losing 25 kg and having severe dysphagia. The GFP, weight 520 g and size 21 × 9 × 7 cm, was removed in toto with a cervical excision following intraluminal marking of the base of the polyp during oesophagoscopy. On histological examination the GFP was found to represent a well-differentiated liposarcoma.

Incidence and severity of dysphagia after anterior cervical discectomy and fusion with zero-profile spacer: prospective study with 3-years follow-up

INTRODUCTION

Dysphagia after anterior cervical discectomy and fusion (ACDF) is a regular complication. The aim of this study was to identify risk factors for incidence and severity of dysphagia after ACDF with zero-profile spacer.

METHODS

Incidence and severity of dysphagia was evaluated preoperatively and for time of three years after ACDF (regular outpatient check-ups) ‒ prospective study with 3-years follow-up. Severity of dysphagia was assessed subjectively using Bazaz‒Yoo dysphagia score. Influence of selected factors on the incidence and severity of postoperative dysphagia was evaluated. Following statistical methods were used: Fisher's exact test, unpaired Student's t-test, one-way ANOVA and Spearman's correlation coefficient. Level of significance was defined as p ˂ 0.05. Correlations between paired parameters were evaluated according to Spearman's correlation.

RESULTS

Our study included 133 patients who underwent one-, two- or three-level ACDF with zero-profile spacer in years 2013‒2018. Myelopathy and GERD had significant impact on incidence and severity of pre-existing dysphagia. Risk factors for incidence of dysphagia after ACDF were number of treated segments, myelopathy, pre-existing dysphagia and surgery of C4/5 segment. Age of patients, duration of surgery and pre-existing dysphagia correlated positively very weakly to weakly with severity of dysphagia after ACDF. Number of treated segments, myelopathy, GERD and surgery of the C4/5 segment were risk factors for greater severity of postoperative dysphagia.

CONCLUSION

Risk factors for incidence and severity of pre-existing dysphagia were myelopathy and GERD. Risk factors for dysphagia incidence after ACDF were number of treated segments, pre-existing dysphagia, myelopathy and surgery of C4/5 segment (Tab. 6, Fig. 1, Ref. 30).

Cricopharyngeal muscle origin transection for oropharyngeal dysphagia, a novel surgical technique

BACKGROUND

Cricopharyngeal myotomy improves pharyngeal dysphagia by resecting the cricopharyngeal muscle.

METHODS

Our procedure, cricopharyngeal muscle origin transection (CPM-OT) is performed through a midline skin incision at the cricoid cartilage level under local anesthesia.

CONCLUSIONS

Sixteen patients demonstrated preservation of vocal fold movement without laryngeal nerve injury immediately after CPM-OT in the awake state during aspiration prevention surgery using the glottic closure technique. Postoperative videofluoroscopic examination of swallowing revealed the cricopharyngeal bar was absent and pharyngeal passage of the bolus and Food Intake LEVEL Scale was improved in all patients. CPM-OT is a feasible and less invasive treatment option.

SX-ELLA biodegradable stent for benign oesophageal strictures: a systematic review and proportion meta-analysis

Background

This systematic review aimed to analyse the use of the SX-ELLA biodegradable stent (BDS) for benign oesophageal strictures through the assessment of clinical and technical success, differences in pre- and post-BDS insertion dysphagia scores, rates of stent migration, and safety.

Methods

A systematic review was reported according to PRISMA guidelines, with a prospectively registered protocol. The databases PubMed, Embase, SCOPUS, and ClinicalTrials.gov were searched up to March 2022. Studies assessing the use of the SX-ELLA BDS in adults with benign oesophageal strictures were included. A pooled data analysis was conducted to analyse the clinical and technical success associated with BDS use, rate of stent migration, and safety.

Results

Of the 1509 articles identified, 16 studies treating 246 patients were eligible for inclusion. BDS was clinically successful in 41.9% of cases (95% CI = 35.7 – 48.1%), defined as those who experienced complete symptom resolution following BDS insertion. Technical success was achieved in 97.2% of patients (95% CI = 95.1 – 99.3%). A pooled analysis concluded a decrease in mean dysphagia score of 1.8 points (95% CI = 1.68 – 1.91) following BDS insertion. Re-intervention was required in 89 patients (36.2%, 95% CI = 30.2 – 42.2%), whilst stent migration occurred in 6.5% of patients (95% CI = 3.4 – 9.6%). A total of 37 major clinical complications related to BDS insertion were reported (15.0%, 95% CI = 10.5 – 19.5%).

Conclusion

The pooled data analysis demonstrates the high technical and moderate clinical success of the SX-ELLA biodegradable stent, supporting its use for benign oesophageal strictures in adults. However, greater evidence is required for more robust conclusions to be made in terms of success when compared to alternative methods of intervention, such as endoscopic dilation.
