Pancreaticopleural fistula causing pleural effusion: a case report and review of the literature.

BACKGROUND: Pancreaticopleural fistula is a rare complication of pancreatitis and poses diagnostic and therapeutic challenges. This case report sheds light on the unique challenges posed by pancreaticopleural fistula as a rare complication of pancreatitis. The aim is to contribute valuable insights to the scientific literature by presenting a case involving a middle-aged man with acute necrotizing pancreatitis and associated pleural effusion. CASE PRESENTATION: A 41-year-old Asian male with a history of pancreatitis and chronic alcohol use presented with severe dyspnea, chest pain, and left-sided pleural effusion. Elevated serum amylase lipase levels and imaging confirmed acute necrotizing pancreatitis with a computed tomography severity index of 8/10. Magnetic resonance cholangiopancreatography revealed pancreatic necrosis and pseudocyst formation and findings suggestive of pancreaticopleural fistula. The patient was then treated with octreotide therapy. CONCLUSION: The management of pancreaticopleural fistula demands a comprehensive and individualized approach. Recognition guided by high clinical suspicion coupled with appropriate investigations and a careful balance between medical, endoscopic, and surgical interventions is crucial for achieving favorable outcomes. This case report adds to the scientific literature by providing insights into the complexities of pancreaticopleural fistula and emphasizing the importance of personalized strategies in its management.

Chinese expert consensus on interventional diagnosis and management of acquired digestive-respiratory tract fistulas (second edition).

Acquired digestive-respiratory tract fistulas occur with abnormal communication between the respiratory tract and digestive tract caused by a variety of benign or malignant diseases, leading to the alimentary canal contents in the respiratory tract. Although various departments have been actively exploring advanced fistula closure techniques, including surgical methods and multimodal therapy, some of which have gotten good clinical effects, there are few large-scale evidence-based medical data to guide clinical diagnosis and treatment. The guidelines update the etiology, classification, pathogenesis, diagnosis, and management of acquired digestive-respiratory tract fistulas. It has been proved that the implantation of the respiratory and digestive stent is the most important and best treatment for acquired digestive-respiratory tract fistulas. The guidelines conduct an in-depth review of the current evidence and introduce in detail the selection of stents, implantation methods, postoperative management and efficacy evaluation.

Nonsurgical Risk Factors Associated With Pharyngocutaneous Fistula in Patients Who Have Undergone Laryngectomy.

Importance: Pharyngocutaneous fistula (PCF) is a serious complication after total laryngectomy. Despite the well-described clinical risk factors for PCF and its association with poor quality of life, there is a paucity of data on the nonclinical factors that may be associated with this complication. Objective: To determine whether nonclinical risk factors (eg, age, sex, race and ethnicity) are associated with an increased risk of developing a PCF after total laryngectomy, and whether or not the method of reconstruction explains any differences found. Design, Setting, and Participants: This retrospective multicenter cohort study used data from a nationally validated, risk-adjusted, outcomes-based, surgical quality improvement database (the National Surgical Quality Improvement Program) to examine outcomes in patients who underwent a total laryngectomy from 2005 to 2018. The database was queried from January 1, 2005, to December 31, 2018; data analyses were performed from September 1, 2020, to March 31, 2021. Main Outcomes and Measures: The primary outcome was development of a PCF within 30 days of a total laryngectomy. Patient characteristics, including age, sex, race and ethnicity, comorbidities, and mode of reconstruction, were analyzed. Results: A cohort of 1573 adult patients (median age [IQR], 63 [56-71] years; 1280 [81.4%] men; 293 [18.6%] women; 1001 [63.6%] non-Hispanic White individuals) had undergone a total laryngectomy during the study period and were included in the analyses. The overall rate of PCF formation was 4.3% (68 of 1573 patients). Hispanic patients had the highest rate (9.5%; 9 of 95 patients) of PCF formation, which was more than twice the rate among non-Hispanic White patients (3.8%; 38 of 1001) and non-Hispanic Black patients (4.7%; 11 of 236). After adjusting for clinical and other covariates, women were 1.9 times more likely to develop a PCF compared with men (adjusted odds ratio, 1.90; 95% CI, 1.08-3.35). We also found that the odds of developing a PCF were 3-fold higher among Hispanic patients compared with non-Hispanic White patients (adjusted odds ratio, 2.96; 95% CI, 1.36-6.47). The type of reconstruction did not differ across age or race and ethnicity after controlling for clinical risk factors. Conclusions and Relevance: This multicenter cohort study found that 2 nonclinical risk factors-Hispanic ethnicity and female sex-were associated with an increased risk of PCF formation. Knowledge of these risk factors should be included in patient-physician decision-making as well as future interventions to decrease the rate of PCF formation after laryngectomy.

Post-tracheostomy tracheoinnominate fistula: endovascular treatment.

OBJECTIVE: Tracheoinnominate fistula (TIF) is a rare and frequently lethal complication of tracheostomies. Immediate bleeding control and surgical treatment are essential to avoid death. This report describes the successful endovascular treatment of TIF in a preschooler and reviews the literature concerning epidemiology, diagnosis, prophylaxis, and treatment of TIF in pediatric patients. CASE DESCRIPTION: A tracheostomized neurologically impaired bed-ridden three-year-old girl was admitted to treat an episode of tracheitis. Tracheostomy had been performed two years before. The child used a plastic cuffed tube continually inflated at low pressure. The patient presented two self-limited bleeding episodes through the tracheostomy in a 48h interval. A new episode was suggestive of arterial bleeding, immediately leading to a provisional diagnosis of TIF, which was confirmed by angiotomography, affecting the bifurcation of the innominate artery and the right tracheal wall. The patient was immediately treated by the endovascular placement of polytetrafluoroethylene (PTFE)/nitinol stents in Y configuration. No recurrent TIF, neurological problems, or right arm ischemia have been detected in the follow-up. COMMENTS: TIF must be suspected after any significant bleeding from the tracheostoma. Endovascular techniques may provide rapid bleeding control with low morbidity, but they are limited to a few case reports in pediatric patients, all of them addressing adolescents. Long-term follow-up is needed to detect whether stent-related vascular complications will occur with growth.

Association of Pharyngocutaneous Fistula With Cancer Outcomes in Patients After Laryngectomy: A Multicenter Collaborative Cohort Study.

Importance: Pharyngocutaneous fistula (PCF) results in an inflammatory reaction, but its association with the rate of locoregional and distant control, disease-free survival, and overall survival in laryngeal cancer remains uncertain. Objective: To determine if pharyngocutaneous fistula after salvage laryngectomy is associated with locoregional and distant control, disease-free survival, and/or overall survival. Design, Setting, and Participants: A multicenter collaborative retrospective cohort study conducted at 5 centers in Canada and the US of 550 patients who underwent salvage laryngectomy for recurrent laryngeal cancer from January 1, 2000, to December 31, 2014. The median follow-up time was 5.7 years (range, 0-18 years). Main Outcomes and Measures: Outcomes examined included locoregional and distant control, disease-free survival, and overall survival. Fine and Gray competing risk regression and Cox-proportional hazard regression models were used for outcomes. Competing risks and the Kaplan-Meier methods were used to estimate outcomes at 3 years and 5 years. Results: In all, 550 patients (mean [SD] age, 64 [10.4] years; men, 465 [85%]) met inclusion criteria. Pharyngocutaneous fistula occurred in 127 patients (23%). The difference in locoregional control between the group of patients with PCF (75%) and the non-PCF (72%) group was 3% (95% CI, -6% to 12%). The difference in overall survival between the group with PCF (44%) and the non-PCF group (52%) was 8% (95% CI, -2% to 20%). The difference in disease-free survival between PCF and non-PCF groups was 6% (95% CI, -4% to 16%). In the multivariable model, patients with PCF were at a 2-fold higher rate of distant metastases (hazard ratio, 2.00; 95% CI, 1.22 to 3.27). Distant control was reduced in those with PCF, a 13% (95% CI, 3% to 21%) difference in 5-year distant control. Conclusions and Relevance: This multicenter retrospective cohort study found that development of PCF after salvage laryngectomy is associated with an increased risk for the development of distant metastases.

A rare case of lung abscess due to esophageo-pulmonary fistula in asymptomatic carcinoma of esophagus.

Acquired esophago-respiratory fistulae are usually esophago-tracheal or esophago-bronchial. Esophago-pulmonary fistulae are rare. Most patients present with cardinal symptoms of esophageal carcinoma or esophago-pulmonary fistula leading to early diagnosis. We report a 56-year-old female with an unusual presentation. She presented with high grade fever with chills and rigor, cough with mucopurulent expectoration and shortness of breath for 15 days without dysphagia, nausea, vomiting or chest pain. Clinically and radiologically a diagnosis of lung abscess was entertained and she was treated with multiple antibiotics without any improvement. Contrast Enhanced Computed Tomography (CECT) chest revealed esophageal malignancy with esophageal-pulmonary fistula communicating with abscess cavity. Patient responded to palliation with self-expandable esophageal stent and drainage of abscess. Although rare, asymptomatic malignant esophageal disease should be considered in the differential diagnosis of lung abscess, which does not follow a usual course. Keywords: Lung abscess, Esophageal cancer, Esophageo-pulmonary fistula, Self expandable metallic stent.

Aortotracheal fistula after slide tracheoplasty in a patient with dextrocardia, left pulmonary artery sling and tracheal stenosis: a case report.

BACKGROUND: Aortotracheal fistula (ATF) is an uncommon and fatal complication of tracheal or aortic surgery, especially among pediatric patients. CASE PRESENTATION: We reported a case in a 1-year-old boy with dextrocardia, left pulmonary artery sling and long segment tracheal stenosis. He received slide tracheoplasty at 9 months of age and had post-operative refractory granulation at distal trachea status post repeated balloon dilatation and laser vaporization. Episodes of hemoptysis occurred on post-operative day 81. Bronchoscopy revealed a pulsating pseudoaneurysm at lower trachea which ruptured during the procedure Urgent surgical repair under cardiopulmonary bypass with deep hypothermic circulatory arrest was done. No recurrent bleeding or significant neurologic deficits noticed at a 4-month follow-up. CONCLUSION: Congenital anomaly that changes the spatial relationship between trachea and aorta could have contributed to formation of ATF. This warrant future attention when managing tracheal granulation with this not uncommon anatomy.

Postoperative Bronchopleural Fistula: A Conservative Way of Treatment in Selected Cases.

BACKGROUND: Postoperative bronchopleural fistula represents a challenging issue for thoracic surgeons. The treatment options reported include bronchoscopic or surgical procedures but the method yielding the best results remains unclear. METHODS: In our thoracic surgery department, between January 2011 and June 2020, 11 patients treated conservatively for early bronchopleural fistula after lobectomy or bilobectomy were reviewed. The fistula size ranged between 2 and 3 mm and complete suture dehiscence. RESULTS: In all 11 patients favorable conditions such as clinical stability, complete expansion of the remaining lung, and resolution of the pleural infection allowed a successful conservative treatment with chest tube drainage. CONCLUSION: In selected cases, conservative management of early bronchopleural fistula after lobectomy or bilobectomy may be an alternative therapeutic option to bronchoscopic or surgical procedures, regardless of the fistula size.

Bilious pleuritis due to hepatic microwave ablation: Two illustrative cases and literature review.

Ultrasound guided percutaneous thermal ablation has been well acknowledged in treating hepatic malignancy. Although thermal ablation is safe for the treatment, it may induce some lethal complications such as diaphragmatic injury, bile-stained pleural fistula, and bilious pleuritis.We presented 2 cancer patients in hepatic diaphragmatic dome showed diaphragmatic injury, bile-stained pleural fistula, and bilious pleuritis after microwave ablation (MVA). The symptoms were attenuated after chest drainage and anti-infection therapy. In the literature review, 17 articles published in the recent 10 years on diaphragmatic injury after MVA for treating hepatic cancer were available. Twenty-three cases were obtained, among which 2 showed bilious pleuritis after radiofrequency treatment. Most of the lesions were adjacent to the diaphragma. Among the articles reporting the localization of lesions, most of the cases showed lesions in S8, 2 in S7, 3 in S4, and 3 in S5, respectively. Surgical recovery was required for the patients with massive diaphragmatic injury. Only 2 cases underwent thorascopic surgery. After chest drainage and anti-infection, their symptoms were attenuated to some extent.Radiofrequency or MVA may induce pleural effusion, and special attention should be paid to the diaphragmatic injury induced by thermal ablation.

Case report: the thoracoscopic surgery in peritoneal-pleural leakage. A valid therapeutic strategy.

Pleuro-peritoneal leakage is an uncommon complication of peritoneal dialysis (PD). In this study, we report the case of a male patient (age 83), treated with PD (daytime single-exchange). In October 2019, hospitalization was necessary due to dyspnoea and a reduction of peritoneal ultrafiltration. A right pleural leakage resulted at chest x-ray. A regression of the pleural leakage was immediately observed after interrupting PD. It was then performed a pleuro-peritoneal CT scan at baseline, followed by a second scan performed 4 hours after the injection of 2 L of isotonic solution with 100ml of contrast medium, which evidenced a pleuro-peritoneal communication. It was then decided to perform a video-assisted thoracoscopic surgery (VATS), that showed no evidence of diaphragm communication. It was then executed a pleurodesis using sterile talcum. The patient was released on the 3rd day, with a conservative therapy and a low-protein diet. After 2 weeks a new pleuro-peritoneal CT scan with contrast medium was executed. This time the scan evidenced the absence of contrast medium in the thoracic cavity. The patient then resumed PD therapy, with 3 daily exchanges with isotonic solution (volume 1.5 L), showing no complications. Concerning the treatment of pleuro-peritoneal leakage, VATS allows both the patch-repairing of diaphragmatic flaws and the instillation of chemical agents. In our case, VATS allowed the chemical pleurodesis which in turn enabled, in just 2 weeks of conservative treatment, the resuming of PD. In conclusion, this methodology is a valid option in the treatment of pleuro-peritoneal leakage in PD patients.

[Endoscopic bronchial valve treatment of bronchopleural fistala and air leakage]. / Endoskopicheskaya klapannaya bronkhoblokatsiya pri lechenii bronkhoplevral'nykh svishchei i utechki vozdukha.

OBJECTIVE: To evaluate an effectiveness of endobronchial valve treatment of patients with bronchopleural fistulas and prolonged air leakage. MATERIAL AND METHODS: Endobronchial valve treatment was analyzed in 115 patients with bronchopleural fistulas or postoperative air leakage. All patients were divided into 5 groups depending on disease: bullous emphysema, acute purulent lung diseases, chronic purulent lung and pleural diseases, bullous emphysema complicated by pneumothorax with failed pleural cavity, other lung diseases associated with prolonged postoperative air leakage. RESULTS: Endobronchial valve treatment was effective in more than 70% patients. There were no intraoperative and postoperative complications. CONCLUSION: Endobronchial valve treatment is a highly effective minimally invasive method for treating patients with bronchopleural fistulas and postoperative air leakage.

Management of Complications After Lung Resection: Prolonged Air Leak and Bronchopleural Fistula.

Prolonged air leak or alveolar-pleural fistula is common after lung resection and can usually be managed with continued pleural drainage until resolution. Further management options include blood patch administration, chemical pleurodesis, and 1-way endobronchial valve placement. Bronchopleural fistula is rare but is associated with high mortality, often caused by development of concomitant empyema. Bronchopleural fistula should be confirmed with bronchoscopy, which may allow bronchoscopic intervention; however, transthoracic stump revision or window thoracostomy may be required.

Management of Complications After Esophagectomy.

Esophagectomy is a complex operation with many potential complications. Early recognition of postoperative complications allows for the best chance for patient survival. Diagnosis and management of conduit complications, including leak, necrosis, and conduit-airway fistulae, are reviewed. Other common complications, such as chylothorax and recurrent laryngeal nerve injury, also are discussed.

Management of thoracogastric airway fistula after esophagectomy for esophageal cancer: A systematic literature review.

BACKGROUND: Thoracogastric airway fistula (TGAF) is a serious complication of esophagectomy for esophageal cancer. We conducted a systematic review of the appropriate therapeutic options for acquired TGAF. METHODS: We performed a literature search to identify relevant studies from PubMed, EMBASE, and Web of Science using the search terms "gastric airway fistula", "gastrotracheal fistula", "gastrobronchial fistula", "tracheogastric fistula", "bronchogastric fistula", "esophageal cancer", and "esophagectomy". RESULT: Twenty-four studies (89 patients) were selected for analysis. Cough was the main clinical presentation of TGAF. The main bronchus was the most common place for fistulas (53/89), and 29 fistulas occurred in the trachea. Almost 73% (65/89) of patients underwent non-surgical treatment of whom 87.7% (57/65) received initial fistula closure. Twenty-three patients underwent surgery, including 19 (82.6%) with initial closure. The 1-, 2-, 3-, 6-, and 9-month survival rates in patients who underwent surgical repair were 95.65%, 95.65%, 82.61%, 72.73%, and 38.10%, respectively, and the equivalent survival rates in patients with tracheal stent placement were 91.67%, 86.67%, 71.67%, 36.96%, and 13.33%, respectively. CONCLUSION: TGAF should be suspected in patients with persistent cough, especially in a recumbent position or associated with food intake. Individualized treatment should be emphasized based on the general condition of each patient.
