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&gt.

The "Hitch-Stitch" for Preventing High Tracheal Stent Migration: Expanding Indications and Extended Experience.

Airway stenting is a standard treatment option for tracheo-bronchial obstruction and other conditions like tracheo-esophageal fistula (TEF). To prevent stent migration, a percutaneous fixation strategy called the "hitch-stitch" was described in 2016 as an efficient technique. We describe an extended experience of the "hitch-stitch" for silicone stents in high tracheal stenting situations and expanding indications to metal stents. Seventy-four percutaneous stitches were placed in 54 patients (36 males and 18 females). The mean age of the patients was 42 (±19) years. The indication for stenting was tracheal stenosis in 63/74 (85%) cases and TEF in 11/74 (15%) cases. Silicone stents were used in 56/74 (75.5%) cases while self-expanding metal stents (SEMS) were used in 18/74 (24.5%) cases. The majority of the stents (62/74, 85%) were high tracheal stents. The "hitch-stitch" as an anti-migration strategy had a high success rate, with distal stent migration in only 2 cases (2.7%) as the stitch had given way-these were repositioned and hitched with double stitches. Minor complications included delayed skin healing (2.8%) and suture site infection (1.4%), which was successfully managed with oral antibiotics. Stitch removal was easy with no complications. In this large series of percutaneous "hitch-stitch" as a stent migration prevention strategy, long-term data shows it is safe and effective in an expanded cohort of silicone stents. Its extended utility is the successful application to metal stents, especially in TEF, where the consequences can be deleterious. It is simple to do, with minimal extra requirements and not associated with any significant complications.

Breastfeeding practices among infants at Madina Teaching Hospital in Faisalabad: A comprehensive analysis.

Objective: To gain insight into the breastfeeding practices of new mothers within a tertiary care facility. Study Design: Descriptive, Cross-sectional Approach. Setting: Department of Pediatric Medicine, Madina Teaching Hospital in Faisalabad. Period: Jan 2023 to June 2023. Methods: The study included 350 infants, of both genders, aged between 6 months and 1 year, who were attending the outpatient department for a routine checkup. Infants with congenital respiratory or cardiac conditions, as well as congenital anomalies such as cleft lip, diaphragmatic hernia, tracheoesophageal fistula, and congenital pneumonia at birth were excluded from the study. The researcher in training meticulously recorded data in the structured study Performa, utilizing this instrument to gather information on breastfeeding practices. Results: Findings revealed that 34.57% of mothers initiated breastfeeding within an hour after childbirth, while 53.43% did so between one and twenty-four hours later. Additionally, 30.57% of mothers chose not to provide their newborns with colostrum, whereas 69.43% did. Only 32.86% of women exclusively breastfed their infants. Furthermore, 35.71% of mothers fed their babies honey, 33.71% used ghutti, 17.14% opted for top feed, and 1.43% provided water. A backache hindered 32% of women from breastfeeding, while weakness affected 40.57%. Additionally, nostalgia, experienced by 13.43% of mothers, and depression experienced by 11.71%, also posed obstacles to breastfeeding. Conclusion: The study indicated that while the majority of mothers possessed knowledge about breastfeeding, there was a noticeable gap between knowledge and its application in practice. Surprisingly, a relatively small percentage of women engaged in exclusive breastfeeding.

Colorimetric CO2 Detector to Improve Effective Mask Ventilations in Very Preterm Infants: A Pilot Randomized Controlled Study

Introduction: End-tidal CO2 (ETCO2) detector is currently recommended for confirmation of endotracheal tube placement during neonatal resuscitation. Whether it is feasible to use ETCO2 detectors during mask ventilation to reduce risk of bradycardia and desaturations, which are associated with increased risk of death in preterm babies, is unknown. Methods: This is a pilot randomized controlled trial (NCT04287907) involving newborns 24 + 0/7 to 32 + 0/7 weeks gestation who required mask ventilation at birth. Infants were randomized into groups with or without colorimetric ETCO2 detectors. Combined duration of any bradycardia (<100 bpm) and time below prespecified target oxygen saturation (SpO2) as measured by pulse oximetry were compared. Results: Fifty participants were randomized, 47 with outcomes analysed (2 incomplete data, 1 postnatal diagnosis of trachea-oesophageal fistula). Mean gestational age and birthweight were 28.5 ± 1.9 versus 29.4 ± 1.6 weeks (p = 0.1) and 1,252.7 ± 409.7 g versus 1,334.6 ± 369.1 g (p = 0.5) in the intervention and control arm, respectively. Mean combined duration of bradycardia and desaturation was 276.7 ± 197.7 s (intervention) and 322.7 ± 277.7 s (control) (p = 0.6). Proportion of participants with any bradycardia or desaturation at 5 min were 38.1% (intervention) and 56.5% (control) (p = 0.2). No chest compressions, epinephrine administration, or death occurred in the delivery room. Conclusion: This pilot study demonstrates the feasibility of a trial to evaluate colorimetric ETCO2 detectors during mask ventilation of very preterm infants to reduce bradycardia and low SpO2. Further assessment with a larger population will be required to determine if ETCO2 detector usage at resuscitation reduces risk of adverse outcomes, including death and disability, in very preterm infants.

Air Leak with Abdominal Distension in Severe ARDS: Beware of Tracheoesophageal Fistula!

Air Leak with Abdominal Distension in Severe ARDS: Beware of Tracheoesophageal Fistula!

Modified stent for the treatment of tracheomegaly combined with a tracheoesophageal fistula: a case reportStent.

Tracheoesophageal fistulas (TEFs) are common in clinical practice and we address them in different ways according to their etiologies. Herein, we present a case of tracheomegaly combined with a TEF after long-term tracheotomy. We placed a modified silicone stent into the trachea to simultaneously cover the fistula and maintain an artificial airway for ventilation. After migration of the modified stent, we replaced it with a prolonged tracheotomy tube. This modified stent is a novel clinical attempt at addressing TEFs that should be more thoroughly explored.

Difficult Airway Management with Awake Fiberoptic Intubation and Cross Table Ventilation in a Case of Acquired TEF with Severe Subglottic Stenosis

We report a case of 30-year male who presented with Acquired Tracheoesophageal Fistula with subglottic stenosis and Aspiration Pneumonitis. Patient was managed with Feeding Jejunostomy, Tracheoesophageal Fistula repair and Tracheoplasty, after which patient recovered well. Difficult airway was managed by Awake Fiberoptic Intubation and cross-table ventilation through flexometallic tube intraoperatively during TEF repair.

Timing of Complications in Open Airway Reconstruction.

Tracheal resection (TR) and cricotracheal resection (CTR) are performed for patients with airway stenosis, tracheal tumor, and tracheoesophageal fistula. Post-operative complications include airway edema requiring reintubation, hematoma, anastomotic dehiscence, restenosis, and death. Although these complications and associated risk factors have been well described, the time where clinical suspicion should be highest post operatively has not been characterized. Patients who underwent TR or CTR at a single center between 2015 and 2022 were reviewed. Variables including demographics and comorbidities were recorded. Rate, nature, and time in days of post-operative complications were evaluated. Sixty-nine cases were reviewed. Average patient age was 46.8 years old and 63.8% were male. The average follow-up period was 625 ± 724 days. 19 (27.5%) patients experienced one or more major complications including four (5.8%) who died. Eight (11.6%) patients required reintubation and 4 (5.8%) patients underwent revision tracheostomy. Most complications occurred within 8 days of surgery. Restenosis was noted an average of 42.6 days after surgery, with no new restenosis occurring after 3 months. In this single-center study, most post-operative complications after TR or CTR, including hematoma and anastomotic dehiscence, occurred within 8 days post-operatively. Restenosis was noted approximately 1-3 months after surgery. This may inform clinical decision-making regarding patient monitoring and surveillance after open airway surgery. 4 Laryngoscope, 134:3527-3531, 2024.

Latissimus dorsi myocutaneous free flap for the laryngopharyngectomy defect.

Partial or total laryngopharyngectomy defects have traditionally been reconstructed using the radial forearm, anterolateral thigh, or jejunal free flaps. The latissimus dorsi myocutaneous free flap (LDMFF) is an option for high-risk patients with complex laryngopharyngeal ± cutaneous neck defects. Retrospective single-surgeon case series from 2017 to 2022. Outcomes were assessed at both the back donor site and head and neck. Twenty-four patients were identified. Flap survival was 100%. There was 1 (4.2%) pharyngocutaneous fistula and 2 (8.3%) tracheo-esophageal peristomal fistulas. At last follow-up, 17 (71%) were sustaining weight on oral intake, and 7 (29%) were G-tube dependent with 4 of these able to do some type of oral intake. Seven (29.2%) had post-operative stricture/stenosis requiring dilation. There were only minor donor site complications, all managed conservatively. The LDMFF can be a robust reconstructive option, particularly for radiated high-risk patients with complex pharyngeal defects, including skin.

Pedicled pericardial patch in tracheal reconstruction in children – Novel technique to provide vascularized tissue for salvaging difficult airways

BackgroundManagement of large central airway defects are often complex. Children who present with these defects have multiple co-morbidities or have had previous surgeries. Surgical options include various tissue cover for these defects without longer term benefits. Vascularized autologous pericardial patch offers a better solution to these defects by providing vascularity and potential for remodelling in future. Methods41 children (M:F of 24:17) were operated for large trachea-bronchial defects between January 2015 and August 2022. The median age of was 12 months with median weight of 8.9 kg (IQR 3.3 kg–17.7 kg) Causes leading to the central tracheal defect include failed repair of previous trachea-oesophageal fistula (TOF) (n = 21) and acquired fistula due to button battery injury (n = 11). Surgical repair consisted of autologous pedicled pericardial patch repair for the airway defect under cardiopulmonary bypass. ResultsThere were two operative deaths related to extensive sepsis and necrosis of reconstructed trachea. Four children had further reoperation with additional patch. Bronchoscopy was used as surveillance in all these children, with use of airway stents (biodegradable stent) in 9 children. The median ventilation time was 8 days, with tracheostomy being needed in 5 for long term support. ConclusionsAutologous pericardial patch is a versatile technique and can be used to salvage large tracheal defects when other method have failed or not feasible. Tracheomalacia at the site of repair could be managed with biodegradable stents. Vascularity and ciliary function of the patch still needs to be evaluated.

Single-cell analysis reveals the spatial-temporal expression of genes associated with esophageal malformations

Understanding the molecular mechanisms of congenital diseases is challenging due to their occurrence within specific developmental stages. Esophageal malformations are examples of such conditions, characterized by abnormalities in the development of esophagus during embryogenesis. These developmental malformations encompass a range of anomalies, including esophageal atresia, and tracheoesophageal fistula. Here, we investigated the preferential expression of 29 genes that are implicated in such malformations and their immediate interactome (a total of 67 genes). We conducted our analyses across several single-cell atlases of embryonic development, encompassing approximately 150,000 cells from the mouse foregut, 180,000 cells from human embryos, and 500,000 cells from 24 human organs. Our study, spanning diverse mesodermal and endodermal cell populations and early developmental stages, shows that the genes associated with esophageal malformations show their highest cell-type specific expression in lateral plate mesoderm cells and at the developmental stage of E8.75–E9.0 days. In human embryos, these genes show a significant cell-type specific expression among subpopulations of epithelial cells, fibroblasts and progenitor cells including basal cells. Notably, members of the forkhead-box family of transcription factors, namely FOXF1, FOXC1, and FOXD1, as well as the SRY-box transcription factor, SOX2, demonstrate the most significant preferential expression in both mouse and human embryos. Overall, our findings provide insights into the temporal and cellular contexts contributing to esophageal malformations.

Goal-directed fluid therapy guided by plethysmographic variability index versus conventional liberal fluid therapy in neonates undergoing abdominal surgery: A prospective randomized controlled trial.

Intraoperative fluid therapy maintains normovolemia, normal tissue perfusion, normal metabolic function, normal electrolytes, and acid-base status. Plethysmographic variability index has been shown to predict fluid responsiveness but its role in guiding intraoperative fluid therapy is still elusive. The aim of the present study was to compare intraoperative goal-directed fluid therapy based on plethysmographic variability index with liberal fluid therapy in term neonates undergoing abdominal surgeries. A prospective randomized controlled study was conducted in a tertiary care centre, over a period of 18 months. A total of 30 neonates completed the study out of 132 neonates screened. Neonates with tracheoesophageal fistula, congenital diaphragmatic hernia, congenital heart disease, respiratory disorders, creatinine clearance <90 mL/min and who were hemodynamically unstable were excluded. Neonates were randomized to goal-directed fluid therapy group where the plethysmographic variability index was targeted at <18 or liberal fluid therapy group. Primary outcome was comparison of total amount of fluid infused intraoperatively in both the groups. Secondary outcomes included intraoperative and postoperative arterial blood gas parameters, biochemical parameters, use of vasopressors, number of fluid boluses, complications and duration of hospital stay. There was no significant difference in total intraoperative fluid infused [90 (84-117.5 mL) in goal-directed fluid therapy and 105 (85.5-144.5 mL) in liberal fluid therapy group (p = .406)], median difference (95% CI) -15 (-49.1 to 19.1). There was a decrease in serum lactate levels in both groups from preoperative to postoperative 24 h. The amount of fluid infused before dopamine administration was significantly higher in liberal fluid therapy group (58 [50.25-65 mL]) compared to goal-directed fluid therapy group (36 [22-44 mL], p = .008), median difference (95% CI) -22 (-46 to 2). In postoperative period, the total amount of fluid intake over 24 h was comparable in two groups (222 [204-253 mL] in goal-directed fluid therapy group and 224 [179.5-289.5 mL] in liberal fluid therapy group, p = .917) median difference (95% CI) cutoff -2 (-65.3 to 61.2). Intraoperative plethysmographic variability index-guided goal-directed fluid therapy was comparable to liberal fluid therapy in terms of total volume of fluid infused in neonates during perioperative period. More randomized controlled trials with higher sample size are required. Central Trial Registry of India (CTRI/2020/02/023561).

Long-term Airway Outcomes and Interventions in Children With Oesophageal Atresia With Tracheoesophageal Fistula: A 20-year Single Centre Observational Study

BackgroundAirway anomalies, symptoms and interventions are commonly reported in children with oesophageal atresia with tracheoesophageal fistula (OA/TOF). The purpose of this study was to assess the incidence of these airway pathologies and those requiring interventions in the long-term. MethodsA retrospective case note review of all patients admitted to the Neonatal Unit at the Royal Hospital for Children, Glasgow between January 2000 and December 2015 diagnosed with OA/TOF. Included patients had a minimum of 5 years follow-up. Results121 patients were identified. 118 proceeded to OA/TOF repair. 115 patients had long-term follow-up data. Ninety-five (83%) children had one or more airway symptom recorded. Thirty-six (31%) neonates underwent airway endoscopy at the time of their initial OA/TOF repair. Forty-six (40%) children underwent airway endoscopy at a later date due to airway symptoms. Airway pathologies identified included airway malacia, thirty-two (28%), subglottic stenosis, eleven (10%), tracheal pouch, twenty-five (22%), laryngeal cleft, seven (6%) and recurrent fistula, five (4%). Airway interventions included endoscopic division of tracheal pouch, ten (9%), tracheostomy, seven (6%), aortopexy, six (5%), repair of recurrent fistula, five (4%), endoscopic repair of laryngeal cleft, three (3%) and four (3%) required open airway reconstruction for subglottic stenosis. One child (1%) remains tracheostomy dependent. ConclusionsLong-term airway pathologies are common in children with OA/TOF. Many of these are remediable with surgical intervention. Clinicians should be cognisant of this and refer to Airway Services appropriately.

Surgical strategies for benign acquired tracheoesophageal fistula.

Tracheoesophageal fistula (TEF) is characterized by abnormal connectivity between the posterior wall of the trachea or bronchus and the adjacent anterior wall of the oesophagus. Benign TEF can result in serious complications; however, there is currently no uniform standard to determine the appropriate surgical approach for repairing TEF. The PubMed database was used to search English literature associated with TEF from 1975 to October 2023. We employed Boolean operators and relevant keywords: 'tracheoesophageal fistula', 'tracheal resection', 'fistula suture', 'fistula repair', 'fistula closure', 'flap', 'patch', 'bioabsorbable material', 'bioprosthetic material', 'acellular dermal matrix', 'AlloDerm', 'double patch', 'oesophageal exclusion', 'oesophageal diversion' to search literature. The evidence level of the literature was assessed based on the GRADE classification. Nutritional support, no severe pulmonary infection and weaning from mechanical ventilation were the 3 determinants for timing of operation. TEFs were classified into 3 levels: small TEF (<1 cm), moderate TEF (≥1 but <5 cm) and large TEF (≥5 cm). Fistula repair or tracheal segmental resection was used for the small TEF with normal tracheal status. If the anastomosis cannot be finished directly after tracheal segmental resection, special types of tracheal resection, such as slide tracheoplasty, oblique resection and reconstruction, and autologous tissue flaps were preferred depending upon the site and size of the fistula. Oesophageal exclusion was applicable to refractory TEF or patients with poor conditions. The review primarily summarizes the main surgical techniques employed to repair various acquired TEF, to provide references that may contribute to the treatment of TEF.

Perforator-based chimeric ulnar forearm microvascular free tissue transfer reconstruction of post-radiated tracheoesophageal puncture fistulae.

Tracheoesophageal puncture (TEP) performed during total laryngectomy in the primary treatment of laryngeal cancer is the standard method for voice restoration. Following adjuvant radiotherapy, the TEP site can experience complications resulting in a tracheoesophageal fistula (TEF) with chronic leakage making oral alimentation unsafe due to aspiration. Here, we describe a technique using chimeric ulnar artery perforator forearm free flaps (UAPFF) in the reconstruction of these complex deformities. Four patients underwent chimeric UAPFF reconstruction of TEP site TEFs following primary TL with TEP and adjuvant radiotherapy. No flap failures or surgical complications occurred. Average time from end of radiotherapy to persistent TEF was 66 months (range 4-190 months). All patients had resolution in their TEF with average time to total oral diet achievement of 22 days (14-42 days). Chimeric UAPFF reconstruction is a safe and effective method to reconstruct recalcitrant TEP site TEFs.

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

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

Delayed Presentation of Button Battery Ingestion in a 6-year-old Girl – A Case Report

Foreign body ingestion is a common presentation to Otorhinolaryngology Department (ORL) especially among pediatrics population. Foreign body can be food or non-food related substances. Button battery ingestion is a life-threatening emergency which can cause injuries such as oesophageal strictures, perforations, tracheoesophageal fistulas, mediastinitis and aortoesophageal fistulas. The extent of damage increases with the duration the button battery remains lodged, underscoring the importance of promptly identifying ingestion. We present a case of a child with a delayed presentation of battery ingestion and a complication of esophageal injury.
