RESUMO
INTRODUCTION AND AIMS: PEG removal in head and neck cancer patients (HNCPs) is performed after treatment, in case of disease remission and after adequate oral intake is resumed. The PEG tract usually closes spontaneously within 2-3 days. Persistent gastrocutaneous fistula (GCF) is a rare complication after PEG tube removal and is characterized by the persistence of gastric leakage through the fistulous tract for more than 1 month. Our main goal was to access the incidence and the success of a treatment algorithm for GCF in HNCPs. METHODS: Retrospective unicentric study of HNCPs referred for PEG removal between 2014 and 2018. The patients with GCF were selected and their sequential treatment was reviewed. RESULTS: In 331 patients with PEGs removed, 19 (5.7%) GCFs were documented. Medical therapy (4-8 weeks) was performed with clinical success (definitive closure of the GCF) in 12 (63.2%) patients. The remaining seven patients required endoscopic or surgical treatment. In four, endoscopic treatment had technical and clinical success (in three patients with fulguration of the gastric leak edges with argon plasma coagulation, silver nitrate in the path and external orifice, and closure of the internal orifice with hemoclips and in one with an over-the-scope-clip). Only three patients underwent surgery, one due to clinical failure of sequential endoscopic therapy and two had direct surgery. CONCLUSION: GCF occurs rarely after PEG removal in HNCPs. Medical therapy is usually effective and should be maintained for at least 8 weeks. Endoscopic therapy is an effective second-line option with and surgery rarely required.

Primary esophageal cancer (EC) frequently presents as a locally advanced disease with airway involvement. Placement of combined esophageal and airway stents has been reported in small series to be an effective palliation strategy. Our aims are to present the largest cohort of EC patients who underwent double stent palliation and to evaluate the safety and efficacy of this approach. Longitudinal cohort study of patients with primary EC undergoing two-stage esophageal and airway stent placement at an oncology referral institute (January 2000-January 2019). Assessments: baseline demographics and clinical variables; baseline and week 2 dysphagia, dyspnea and performance status (PS) scores; baseline and week 8 body mass index (BMI); overall survival. Statistics: paired t-test; Kaplan-Meier method. Seventy patients (89% men, mean age 60.20 ± 8.41) underwent double stenting. Esophageal stent was placed for esophageal stenosis and dysphagia (n = 41; placement of a second stent due to recurrence in nine cases) or esophagorespiratory fistulas (ERFs) (n = 29); airway stent was required for ERF sealing (n = 29 + 7 new ERFs after esophageal stent) and to ensure airway patency due to malignant stenosis (n = 29; placement of a second stent due to recurrence in 13 cases) or compression (n = 5). There were 13, endoscopically managed, major complications after esophageal stent [hemorrage (n = 1), migration (n = 5) and new fistulas (n = 7)]. As for airway stents, four major complications were recorded [hemorrage (n = 1) and three deaths due to respiratory infection and ultimately respiratory failure 3-7 days after the procedure]. Overall, patients showed significant improvement in dysphagia and dyspnea symptoms (3.21 vs. 1.31 e 15.56 vs. 10.87; P < 0.001). There was a PS improvement for 89.2% (n = 58) of the patients. BMI at week 8 was comparable to baseline records. Mean survival was 137.83 ± 24.14 days (95% CI: 90.51-185.15). Survival was longer for better PS (PS1, 249.95 days; PS2, 83.74 days; PS3, 22.43 days; PS4, 30.00 days). This is the largest comprehensive assessment of double stent palliation in advanced incurable EC. For both esophageal or airway stenosis and fistula, placement of combined esophageal and airway stents was a feasible, effective, fast-acting and safe modality for symptom palliation and body mass maintenance. Patient autonomy followed symptom improvement. Since it is impossible to provide treatment for cure in most of these cases, this endoscopic strategy, performed in differentiated units with the required technical capacity, may guarantee treatment for the relief of palliative EC.
