Background PIA has been proven to be a predictor for postoperative dysphagia in patients who undergo occipitospinal fusion. However, its predictive effect for postoperative dysphagia in patients who undergo OCF is unknown. The aim of this study was to evaluate the predictive ability of the pharyngeal inlet angle (PIA) for the occurrence of postoperative dysphagia in patients who undergo occipitocervical fusion (OCF). Methods Between 2010 and 2018, 98 patients who had undergone OCF were enrolled and reviewed. Patients were divided into two groups according to the presence of postoperative dysphagia. Radiographic parameters, including the atlas-dens interval (ADI), O-C2 angle (O-C2a), occipital and external acoustic meatus to axis angle (O-EAa), C2 tilting angle (C2Ta), C2-7 angle (C2-7a), PIA and narrowest oropharyngeal airway space (nPAS), were measured and compared. Simple linear regression and multiple regression analysis were used to evaluate the radiographic predictors for dysphagia. In addition, we used PIA = 90° as a threshold to analyze its effect on predicting dysphagia. Results Of the 98 patients, 26 exhibited postoperative dysphagia. Preoperatively, PIA in the dysphagia group was significantly higher than that in the nondysphagia group. We detected that O-C2a, O-EAa, PIA and nPAS all decreased sharply in the dysphagia group but increased slightly in the nondysphagia group. The changes were all significant. Through regression analyses, we found that PIA had a similar predictive effect as O-EAa for postoperative dysphagia and changes in nPAS. Additionally, patients with an increasing PIA exhibited no dysphagia, and the sensitivity of PIA <90° in predicting dysphagia reached 88.5%. Conclusions PIA could be used as a predictor for postoperative dysphagia in patients undergoing OCF. Adjusting a PIA level higher than the preoperative PIA level could avoid dysphagia. For those who inevitably had decreasing PIA, preserving intraoperative PIA over 90° would help avert postoperative dysphagia.

BackgroundLaparoscopic fundoplication (LF), even if performed in specialized centers, can be followed by long-term side effects such as dysphagia, gas bloating or inability to belch. Patients with an ineffective esophageal motility (IEM) and concurrent GERD are prone to postoperative dysphagia after LF. The aim of this study is to evaluate the safety and efficacy of electrical lower esophageal sphincter stimulation in patients with IEM and GERD.MethodsThis is a prospective, open-label single center study. Patients with PPI-refractory GERD and ineffective esophageal motility were included for lower esophageal sphincter electrical stimulation (LES-EST). Patients underwent prospective follow-up including physical examination, interrogation of the device and were surveyed for changes in the health-related quality of life score.ResultsAccording to power analysis, 17 patients were included in this study. Median distal contractile integral (DCI) was 64 mmHg s cm (quartiles 11.5–301). Median total % pH < 4 was 8.9 (quartiles 4–21.6). Twelve patients (70.6%) underwent additional hiatal repair. At 1-month follow-up, none of the patients showed any clinical or radiological signs of dysphagia. There were no procedure related severe adverse events. Mean total HQRL improved from baseline 37.53 (SD 15.07) to 10.93 (SD 9.18) at follow-up (FUP) (mean difference 24.0 CI 15.93–32.07) p < 0.001.ConclusionsLES-EST was introduced as a potential technique to avoid side effects of LF. LES-EST significantly improved health related quality of life and does not impair swallowing in patients with GERD and ineffective esophageal motility.

Study Design A retrospective study Objective To investigate the potential risk factors of dysphagia after anterior cervical discectomy and fusion (ACDF) and to establish and validate a prediction model. Methods The clinical data of 252 patients who underwent anterior cervical discectomy and fusion in our hospital from January 2018 to October 2020 were retrospectively analyzed and divided into the dysphagia group and the non-dysphagia group according to whether dysphagia occurred after surgery. Age, gender, body mass index, smoking and drinking history, hypertension history, diabetes history, disease duration, placement of Hemovac negative pressure drain, number of segments involved in surgery, whether C4-5/C5-6 segment surgery, incision length, incision position, level of preoperative EAT-10 score, whether preoperative tracheal exercise, and changes in cervical curvature before and after surgery were recorded in both groups. Risk factors for postoperative dysphagia were identified and nomogram prediction models were developed. Results A total of 252 patients were included in the study, 115 of whom presented with dysphagia within 1 week after anterior cervical fusion. The results of multivariate logistic regression analysis indicated that male gender (OR = .045, 95% CI .223-.889) and whether preoperative tracheal exercise (OR = .260, 95% CI .107-.633) were independent risk factors associated with reduced incidence of postoperative dysphagia. Conclusion The incidence of dysphagia symptoms after anterior cervical decompression and fusion gradually decreased with the extension of follow-up time, and preoperative tracheal exercise and shortening the operation time may help to reduce the occurrence of postoperative dysphagia.

Background: Anterior cervical discectomy and fusion (ACDF) is a widely performed surgical intervention for cervical spine herniation (CSH) to alleviate symptoms such as pain, weakness, and restricted mobility. Despite its efficacy, ACDF is associated with postoperative complications, notably dysphagia and dysphonia (PDD). Objective: This study investigates the prevalence, severity, and risk factors associated with PDD following ACDF using the validated Dysphagia and Dysphonia Inventory (HSS-DDI) adapted into Greek. Methods: A prospective observational cohort study was conducted at the University General Hospital of Ioannina from May to November 2023. The study involved 40 adult patients who underwent ACDF for CSH. Postoperative dysphagia and dysphonia were assessed using the Ohkuma questionnaire and HSS-DDI at 1 week and 1 month postoperatively. Results: The mean age of participants was 54.78 years, with a majority being male (60%). In terms of body mass index (BMI), 30% of participants had a normal weight, 47.5% were overweight, and 22.5% were obese. This study revealed that dysphagia and dysphonia were common postoperative complications, with improvements noted after one month. Factors such as BMI were statistically significant in influencing dysphagia outcomes, with normal BMI individuals reporting better outcomes than obese participants. Confirmatory factor analysis indicated the need for a larger sample size to confirm subscale validity in the Greek population. Conclusions: Postoperative dysphagia and dysphonia are prevalent following ACDF, but most patients experience improvements within a short period. Identifying risk factors, such as BMI, and utilizing validated assessment tools like the HSS-DDI can help optimize surgical techniques and postoperative care. Further studies with larger sample sizes are recommended for a more comprehensive understanding of these complications.

Background: Excess flexion or extension during occipitocervical fusion (OCF) can lead to postoperative complications, such as dysphagia, respiratory problems, line of sight issues, and neck pain, but posterior fossa decompression (PFD) and OCF require different positions that require intraoperative manipulation. Objective: The objective of this study was to describe quantitative fluoroscopic morphometrics in Chiari malformation (CM) patients with symptoms of craniocervical instability (CCI) and demonstrate the intraoperative application of these measurements to achieve neutral craniocervical alignment while leveraging a single axis of motion with the Mayfield head clamp locking mechanism. Methods: A retrospective cohort study of patients with CM 1 and 1.5 and features of CCI who underwent PFD and OCF at a single-center institution from March 2015 to October 2020 was performed. Patient demographics, preoperative presentation, radiographic morphometrics, operative details, complications, and clinical outcomes were analyzed. Results: A total of 39 patients met the inclusion criteria, of which 37 patients (94.9%) did not require additional revision surgery after PFD and OCF. In this nonrevision cohort, preoperative to postoperative occipital to C2 angle (O-C2a) (13.5° ± 10.4° vs. 17.5° ± 10.1°, P = 0.047) and narrowest oropharyngeal airway space (nPAS) (10.9 ± 3.4 mm vs. 13.1 ± 4.8 mm, P = 0.007) increased significantly. These measurements were decreased in the two patients who required revision surgery due to postoperative dysphagia (mean difference - 16.6°° in O C2a and 12.8°° in occipital and external acoustic meatus to axis angle). Based on these results, these fluoroscopic morphometrics are intraoperatively assessed, utilizing a locking Mayfield head clamp repositioning maneuver to optimize craniocervical alignment prior to rod placement from the occipital plate to cervical screws. Conclusion: Establishing a preoperative baseline of reliable fluoroscopic morphometrics can guide surgeons intraoperatively in appropriate patient realignment during combined PFD and OCF, and may prevent postoperative complications.

Objectives To develop and validate a risk stratification model for postoperative dysphagia in pediatric cardiac surgery patients, focusing on factors relevant to otolaryngologic assessment and implications for Otolaryngology management. Methods Analysis of 174 pediatric patients undergoing cardiac surgery at a tertiary care center between January 1, 2022 and December 31, 2023. Logistic regression was used to develop a risk score based on preoperative and intraoperative factors. Patients were categorized into low, moderate, and high‐risk groups for dysphagia requiring Otolaryngology consultation. Secondary outcomes included impaired vocal fold mobility. Results Of 174 patients, postoperative dysphagia necessitating Otolaryngology evaluation was identified in 102 (58.6%) children. The final predictive model included age at surgery (OR, 0.80; 95% CI, 0.72–0.90; p < 0.001), cardiopulmonary bypass duration (OR, 1.73; 95% CI, 1.23–2.45; p = 0.002), and high‐risk complex procedures (e.g., Norwood) (OR, 6.49; 95% CI, 2.70–15.61; p < 0.001). Model discrimination was good (AUC 0.82). Predicted risk categories showed distinct dysphagia rates among the cohort: low‐risk (24.7% of the cohort, with 30.2% experiencing dysphagia), moderate‐risk (31.6%, with 38.2% experiencing dysphagia), and high‐risk (43.7%, with 89.5% experiencing dysphagia). Among high‐risk patients, 70.6% exhibited impaired vocal fold mobility at long‐term follow‐up. Conclusion This Otolaryngology‐focused risk stratification model identifies pediatric cardiac surgery patients at high risk for postoperative dysphagia and associated impaired vocal fold mobility. Early identification of this population can aid consultation and therapeutic interventions like injection laryngoplasty. Level of Evidence Level 3.

Background/Objectives: The role of double-lumen endotracheal tube (DLT) versus single-lumen endotracheal tube (SLT) use during lung transplantation (LTx) and its effects on postoperative dysphagia have not yet been studied. It has been shown that new-onset oropharyngeal dysphagia (OPD) is common after various thoracic surgeries including lung transplantation and that OPD is associated with increased postoperative complications. Methods: A single-center, retrospective cohort study was performed using a data exploration tool in the electronic medical record. Data included demographic characteristics, medical history, postoperative dysphagia measured by Functional Oral Intake Scale (FOIS) via modified barium swallow study (MBSS) within 5 days of surgery, and other secondary outcomes. Results: In univariate analysis, participants who had a DLT (49 patients) had significantly higher FOIS scores (indicating better swallowing function) as compared to those with an SLT (21 patients) (p = 0.035). Lumen type remained significant in a multivariable model, with use of a DLT showing more than a 5-fold increase in the odds of a higher FOIS score after controlling for other factors (p = 0.004; cumulative OR (95% CI): 5.2 (1.7–15.9)). Participants who had a DLT had shorter hospital length of stay (LOS) (p = 0.017; single 18 days (IQR = 13), double 14 days (IQR 7)). Those who had a DLT experienced significantly greater ventilator-free time at postoperative day 30 compared to those who received an SLT (p = 0.018). ICU LOS was similar between those who received a DLT vs. SLT. Conclusions: Overall, DLT seems to confer reduced new-onset OPD after lung transplantation surgery when compared with SLT. The use of DLT instead of SLT for lung isolation for LTx may have the potential to reduce morbidity and mortality in this population.

Background The management of paraesophageal hernia (PEH) is one of the most debated in surgery. Trends regarding indications, approach (open, laparoscopic, thoracoscopic), sac excision, mesh placement, and routine performance of fundoplication have changed over time. Today, most surgeons tend to perform a laparoscopic PEH repair that entails the excision of the sac, liberal use of a mesh to buttress the hiatus, and the addition of an anti-reflux procedure. Nevertheless, very little has been written on which type of fundoplication should be performed in these patients. Therefore, the goal of our study was to provide an evidence-based overview of which type of fundoplication should be performed during a PEH repair and the role of preoperative function tests in the decision-making Methods We searched the MEDLINE, Cochran, PubMed, Google Scholar, and Embase databases for papers published between 1996 and 2016 pertaining to the surgical treatment of PEH. We hand-searched the bibliographies of included studies and we excluded all reviews and case reports. We selected clinical studies and technical reports. We only considered papers stating rationales for the type of fundoplication performed. Results Our search yielded 24 articles: 17 clinical studies and 7 technical reports. In five of the clinical studies, a fundoplication was added only to patients with reflux symptoms. In all clinical studies, the most performed procedure was a total fundoplication (Nissen or Nissen-Rossetti), whereas a partial fundoplication (Toupet more frequently than Dor) or no fundoplication was reserved to those with impaired esophageal motility. All seven technical reports recommended a tailored approach and suggested adding a partial fundoplication (mainly Toupet) when the manometric findings showed esophageal dismotility. Conclusion The argument of whether or not a fundoplication should be added to a PEH repair in patients without evidence of reflux still persists. However, this review highlights that, when a fundoplication is performed, a tailored approach based on preoperative function tests is almost always preferred.

Objectives Although laparoscopic posterior fundoplication (LPF) i.e., Nissen or Toupet have the proven efficacy for controlling gastro-esophageal reflux surgically, there remain problems with postoperative dysphagia and gas bloat syndrome. To decrease some of these postoperative complications, laparoscopic anterior fundoplication (LAF) was introduced. The aim of this study was to conduct a meta-analysis and systematic review of randomized controlled trials (RCTs) to investigate the merits and drawbacks of LPF versus LAF for the treatment of gastro-esophageal reflux disease (GERD). Data Sources, Study Selection, and Review Methods A search of Medline, Embase, Science Citation Index, Current Contents, PubMed, ISI Web of Science, and the Cochrane Database identified all RCTs comparing different types of LPF and LAF published in the English Language between 1990 and 2013. The meta-analysis was prepared in accordance with the Preferred Reporting Items for Systematic reviews and Meta-analyses (PRISMA) statement. Data was extracted and analyzed on ten variables which include dysphagia score, heartburn rate, redo operative rate, operative time, overall complications, rate of conversion to open, Visick grading of satisfaction, overall satisfaction, length of hospital stay, and postoperative 24-h pH scores. Data Synthesis Nine trials totaling 840 patients (anterior = 425, posterior = 415) were analyzed. There was a significant reduction in the odds ratio for dysphagia in the LAF group compared to the LPF group. Conversely, significant reduction in the odds ratio for heartburn was observed for LPF compared to LAF. Comparable effects were noted for both groups for other variables which include redo surgery, operating time, overall complications, conversion rate, Visick’s grading, patients’ satisfaction, length of hospital stay, and postoperative 24-h pH scores. Conclusions Based on this meta-analysis, LPF compared to LAF is associated with significant reduction in heartburn at the expense of higher dysphagia rate on a short- and medium-term basis. We therefore conclude that LPF is a better alternative to LAF for controlling GERD symptoms.

Aim Postoperative dysphagia after emergency abdominal surgery (EAS) in patients of advanced age has become problematic, and appropriate dysphagia management is needed. This study was performed to identify predictive factors of dysphagia after EAS and to explore the usefulness of swallowing screening tools (SSTs). Methods This retrospective study included 267 patients of advanced age who underwent EAS from 2012 to 2022. They were assigned to a dysphagia group and non‐dysphagia group using the Food Intake Level Scale (FILS) (dysphagia was defined as a FILS level of <7 on postoperative day 10). From 2018, original SSTs including a modified water swallowing test were performed by nurses. Results The incidence of postoperative dysphagia was 22.8% (61/267). Patients were significantly older in the dysphagia than non‐dysphagia group. The proportions of patients who had poor nutrition, cerebrovascular disorder, Parkinson's disease, dementia, nursing‐care service, high intramuscular adipose tissue content (IMAC), and postoperative ventilator management were much higher in the dysphagia than non‐dysphagia group. Using logistic regression analysis, high IMAC, postoperative ventilator management, cerebrovascular disorder, and dementia were correlated with postoperative dysphagia and were assigned 10, 4, 3, and 3 points, respectively, according to each odds ratio. The optimal cut‐off value was 7 according to a receiver operating characteristics curve. Using 1:1 propensity score matching for high‐risk patients, the incidence of postoperative dysphagia was reduced by SSTs. Conclusions The new prediction score obtained from this study can identify older patients at high risk for dysphagia after EAS, and SSTs may improve these patients' short‐term outcomes. This retrospective study included 267 patients of advanced age and was performed to identify predictive factors of dysphagia after emergency abdominal surgery and to explore the usefulness of swallowing screening tools. This study demonstrated that high intramuscular adipose tissue content, postoperative ventilator management, cerebrovascular disorder, and dementia were associated with postoperative dysphagia after emergency abdominal surgery in patients of advanced age. For patients at high risk as identified by our new prediction score that was created based on these risk factors, propensity score‐matching analysis showed that the use of swallowing screening tools can help to prevent postoperative dysphagia.
