A 16-Year-Old Girl with Sinonasal Cutaneous Fistula Following Excision and Radiotherapy for Rhabdomyosarcoma Requiring Reconstructive Surgery Using an Expanded Forehead Flap.

BACKGROUND Sinonasal rhabdomyosarcoma (RMS) is a rare malignancy in children and adolescents. It is aggressive and locally invasive, and can require local postoperative radiotherapy. This report presents the case of a 16-year-old girl with a sinonasal-cutaneous fistula following excision and radiotherapy for rhabdomyosarcoma, which required reconstructive surgery using an expanded forehead flap. CASE REPORT We report the case of a16-year-old girl who was referred to our clinic with sinonasal-cutaneous fistula. Prior to presentation at our department, she presented with bilateral intermittent nasal congestion 3 years ago. At a local hospital, orbital computed tomography and nasal endoscopic biopsy revealed an embryonal rhabdomyosarcoma (ERMS). One month later, skull base tumor resection, nasal cavity and sinus tumor resection, and low-temperature plasma ablation were performed at a local hospital. Two weeks after the operation, the patient received intensity-modulated radiation therapy for a total of 50 Gy. Chemotherapy started 15 days after radiotherapy, using a vincristine, dactinomycin, and cyclophosphamide (VAC) regimen. Approximately 1 month later, an ulcer appeared at the nasal root and the lesion gradually expanded. The patient was referred to our hospital due to the defect. Firstly, a tissue expander was implanted at the forehead for 7 months. Then, the skin around the defect was trimmed and forehead flap was separated to repair the lining and external skin. The flap survived well 1-year after the operation. CONCLUSIONS This report highlights the challenges of post-radiation reconstructive surgery and describes how an expanded forehead flap can achieve an acceptable cosmetic outcome in a patient with a sinonasal-cutaneous fistula.

Vesicocutaneous fistula at site of closed suprapubic tube tract as the first presenting sign of giant bladder stone.

Bladder stones represent approximately 5% of all cases of urolithiasis and are typically identified and managed long before causing irreversible renal injury. We present a case of a man in his 40s with a prior history of a gunshot wound to the abdomen who presented with leakage from a previously healed suprapubic tube tract and was found to have a giant bladder stone with a resulting renal injury. He subsequently underwent a combined open cystolithotomy and vesicocutaneous fistulotomy during his hospitalisation, which helped to improve his renal function. In addition to there being few reported cases of bladder stones >10 cm, this represents the first report in the literature of an associated decompressive 'pop-off' mechanism through a fistulised tract.

Impact of stapler versus manual closure techniques on pharyngocutaneous fistula development post-total laryngectomy: A systematic review and meta-analysis.

Pharyngocutaneous fistula (PCF) is a major complication after total laryngectomy, with significant morbidity and mortality. Whether mechanical stapler closure of the pharynx reduces fistula rates compared to hand-sewn techniques remains unclear. We conducted an updated systematic review and meta-analysis to clarify this question. Five databases were systematically searched from inception through November 2023 for studies comparing stapler versus suture closure for fistula outcomes after laryngectomy. Odds ratios (OR) were pooled using random-effects models and fixed-effects models. Subgroup and sensitivity analyses were performed. Risk of bias was appraised using NHLBI tools. Nine studies with 803 patients were included. Mechanical closure significantly reduced fistula incidence versus suture closure (OR = 0.57, 95% CI 0.34-0.95, p = 0.03). Subgroup analysis found that stapling's protective effect varied by patient age, country/region, linear stapler size and female percentage. Stapling reduced fistula odds by 80% in the Turkey subgroup (OR = 0.20, 95% CI 0.09-0.50) but showed no benefit in other regions. Patients <60 years showed an 84% fistula reduction with stapling (OR = 0.17, 95% CI 0.06-0.45), whereas older subgroups did not. Linear stapler size of 60 mm significantly reduced fistula occurrence while 75 mm did not. There was no evidence that low female percentage mitigated stapling benefits. Mechanical stapler closure after total laryngectomy meaningfully reduces the likelihood of postoperative PCF formation compared to hand-sewn closure, especially for patients younger than 60 years old. The absolute risk reduction supports its utility to prevent this complication.

Utero-cutaneous fistula following caesarean section.

A multiparous woman in her 20s, presented to the clinic with bleeding from caesarean scar site. After clinical examination and radiological evaluation with ultrasound and MR fistulogram, the diagnosis was utero-cutaneous fistula. Complete resection of fistulous tract with uterine defect closure and supportive omental patch placement was done after an intraoperative demonstration of the utero-cutaneous fistula by injecting methylene blue dye. Utero-cutaneous fistula is a rare complication after caesarean section. Cyclical bleeding from an abnormal opening in previous caesarean scar site is the classical presentation of this condition.

Pediatric Tracheotomy Stomal Maturation and Tracheocutaneous Fistulas.

OBJECTIVE: The purpose of this study is to determine whether tracheostomy stomal maturation affects the risk of tracheocutaneous fistula (TCF) in children. METHODS: A retrospective chart review was conducted for all children who both underwent a tracheostomy and were decannulated between 2012 and 2021 at a tertiary children's hospital. Charts were analyzed for demographics, surgical technique, and development of a TCF. TCF was defined as a persistent fistula following 3 months after decannulation. RESULTS: 179 children met inclusion criteria. The median (interquartile range) age at tracheostomy was 1.5 (82.4) months, average (standard deviation [SD]) duration of tracheotomy was 20.0 (20.6) months, and length of follow-up after decannulation (range; SD) was 39.3 (4.4-110.0; 26.7) months. 107 patients (60.0%) underwent stomal maturation and 98 patients developed a TCF (54.7%). Younger age at tracheostomy placement was significantly associated with increased risk of TCF, mean (SD) age 28.4 (51.4) version 80.1 (77.5) months (p < 0.001). Increased duration of tracheostomy was significantly associated with increased risk of TCF, 27.5 (18.4) version 11.0 (18.2) months (p < 0.001). Stomal maturation was not significantly associated with the risk of TCF, including on multivariable analysis adjusting for age at tracheostomy and duration of tracheostomy (p = 0.089). CONCLUSION: Tracheostomy stomal maturation did not affect the risk of TCF in children, even after adjusting for age and duration of tracheostomy. LEVEL OF EVIDENCE: 4 Laryngoscope, 134:2941-2944, 2024.

Prophylactic pectoralis major flap to compensate for increased risk of pharyngocutaneous fistula in laryngectomy patients with low skeletal muscle mass (PECTORALIS): study protocol for a randomized controlled trial.

BACKGROUND: Total laryngectomy (TL) is a surgical procedure commonly performed on patients with advanced laryngeal or hypopharyngeal carcinoma. One of the most common postoperative complications following TL is the development of a pharyngocutaneous fistula (PCF), characterized by a communication between the neopharynx and the skin. PCF can lead to extended hospital stays, delayed oral feeding, and compromised quality of life. The use of a myofascial pectoralis major flap (PMMF) as an onlay technique during pharyngeal closure has shown potential in reducing PCF rates in high risk patients for development of PCF such as patients undergoing TL after chemoradiation and low skeletal muscle mass (SMM). Its impact on various functional outcomes, such as shoulder and neck function, swallowing function, and voice quality, remains less explored. This study aims to investigate the effectiveness of PMMF in reducing PCF rates in patients with low SMM and its potential consequences on patient well-being. METHODS: This multicenter study adopts a randomized clinical trial (RCT) design and is funded by the Dutch Cancer Society. Eligible patients for TL, aged ≥ 18 years, mentally competent, and proficient in Dutch, will be enrolled. One hundred and twenty eight patients with low SMM will be centrally randomized to receive TL with or without PMMF, while those without low SMM will undergo standard TL. Primary outcome measurement involves assessing PCF rates within 30 days post-TL. Secondary objectives include evaluating quality of life, shoulder and neck function, swallowing function, and voice quality using standardized questionnaires and functional tests. Data will be collected through electronic patient records. DISCUSSION: This study's significance lies in its exploration of the potential benefits of using PMMF as an onlay technique during pharyngeal closure to reduce PCF rates in TL patients with low SMM. By assessing various functional outcomes, the study aims to provide a comprehensive understanding of the impact of PMMF deployment. The anticipated results will contribute valuable insights into optimizing surgical techniques to enhance patient outcomes and inform future treatment strategies for TL patients.

Persistent Ostomy Following Percutaneous Endoscopic Gastrostomy Removal: Treatment Strategies.

PURPOSE OF REVIEW: The purpose of this article is to review available literature on management of persistent ostomy following PEG tube removal. We will discuss the incidence of persistent gastrocutaneous fistula (GCF) following PEG tube removal, risk factors for their development, and management strategies that have been proposed and their efficacy. RECENT FINDINGS: The use of over the scope clips (OTSC) have evolved recently in the management of gastrointestinal bleeding, perforation, and fistula closures. OTSC has become more readily available and proven to be effective and safe. Suturing devices have shown promising results. Persistent gastrocutaneous fistula following PEG removal is a rare yet serious complication that can lead to continuous skin irritation and leakage of gastric contents and acid. There are several postulated risk factors but the most important of these is duration of placement. Management can include medical therapy which has recently been shown to be somewhat effective, endoscopic therapy and surgery as a last resort. Overall, the data on GCFs is limited and further study with larger sample size is needed.

Cutaneous fistula formation after thyroid nodule rupture: A rare complication after radiofrequency ablation.

BACKGROUND: With innovative treatment options such as radiofrequency ablation (RFA) for thyroid nodules, new complications are being identified. It is important to define and delineate complications in order to counsel patients appropriately about treatment options and their associated risks and benefits. METHODS: A 46-year-old male presented with a left thyroid nodule (6.5 cm). Fine needle aspiration results were benign. He started to develop intermittent dyspnea and underwent one RFA procedure. Approximately 6 days post-RFA, the neck area was raised and red with blister. The skin overlying the blister underwent eventual dehiscence with fluid spillage. Several months later, MRI imaging showed substernal extension with tracheal deviation. RESULTS: A left thyroid lobectomy was performed with cutaneous excision and successful closure of a fistula. CONCLUSIONS: This is the first reported case of a thyroid nodule rupture following RFA which manifested into a thyro-cutaneous fistula and required surgical intervention.

Pharyngo-cervicospinal fistula with destructive osteomyelitis after laryngopharyngectomy and radiotherapy, managed successfully with a vascularized fibula free flap.

Total laryngectomy is an operation mainly employed in recurrent laryngeal and hypopharyngeal carcinoma after previous radiotherapy. The most feared complication after this procedure is a pharyngocutaneous fistula. An extremely rare complication is the development of osteomyelitis of the cervical spine, which is associated with high rates of neurological impairment and epidural empyema, often requiring surgical treatment. This report describes the case of a patient with neck and shoulder pain and progressive motor weakness of the left deltoid and biceps muscle, caused by a pharyngo-cervicospinal fistula with spinal empyema. This condition resulted in destructive osteomyelitis of the cervical spine. A successful reconstruction of the cervical spine and neopharynx was performed using a free vascularized fibula bone and skin graft in a complex area because of previous treatments. It appears that no similar case has been described previously.

Surgical closure of enlarged tracheoesophageal fistula after laryngectomy: A systematic review of techniques.

OBJECTIVES: The objectives of the study were (1) systematically review the data on surgical closure of enlarged tracheoesophageal fistula after laryngectomy and (2) to perform a comparison of reconstruction of surgical techniques. METHODS: Systematic review was performed using PRISMA methodology. Cumulative patient data were compared between patients reconstructed with vascularized tissue (sternocleidomastoid fascia and muscle, pectoralis major, deltopectoral, radial forearm) and those closed primarily (two-layer, three-layer, and tracheal transposition). RESULTS: Fourteen studies reported outcomes for the reconstruction of tracheoesophageal fistula. Primary closure was used in 98 patients, vascularized flap in 74, and occlusive device in 8. Vascularized flap resulted in successful closure of the fistula in 89 % of cases compared to primary closure in 62 % (p = 0.0003). CONCLUSION: Systematic review of the literature supports an improved surgical closure rate with vascularized flap interposed between the esophageal and tracheal lumens compared to primary closure.

Development of a nomogram for predicting pharyngocutaneous fistula based on skeletal muscle mass and systemic inflammation indices.

BACKGROUND: Laryngeal and hypopharyngeal cancers often require surgical treatment, which can lead to the development of pharyngocutaneous fistula (PCF). Our research aimed to assess the predictive value of skeletal muscle mass (SMM) and systemic inflammation indices for PCF and construct a clinically effective nomogram. METHODS: A nested case-control study of 244 patients matched from 1171 patients with laryngeal or hypopharyngeal cancer was conducted. SMM was measured at the third cervical level based on CT scans. A PCF nomogram was developed based on the univariate and multivariate analyses. RESULTS: Glucose, white blood cell count, platelet-to-lymphocyte ratio, and skeletal muscle index were independent risk factors for PCF. The area under the curve for the PCF nomogram was 0.841 (95% CI 0.786-0.897). The calibration and decision curves indicated that the nomogram was well-calibrated with good clinical utility. CONCLUSIONS: The nomogram we constructed may help clinicians predict PCF risk early in the postoperative period, pending external validation.

[Spontaneous cholecysto-cutaneous fistula: about two cases]. / Fístula colecisto-cutánea espontánea: a propósito de dos casos.

Cholecysto-cutaneous fistula (CCF) is a rare complication of untreated biliary pathology, with fewer than 100 cases documented in the literature. Most are secondary to bacterial infection, although it has also been described in gallbladder adenocarcinoma and post trauma. Its clinical presentation is variable, being able to present systemic affection, and its most frequent external drainage site is in the right hypochondrium. Due to the low incidence of this pathology, and the variety of forms of presentation, its management does not have, to date, standardized bases. We present two cases of patients who consulted in the emergency room at the Hospital Nacional de Clínicas for presenting cholecysto-cutaneous fistula. The treatment of both was surgical.

La fístula colecisto-cutáneas (FCC) es una rara complicación de la patología biliar no tratada, habiendo menos de 100 casos documentados en la literatura. La mayoría son secundarias a infección bacteriana, aunque también fue descripta en el adenocarcinoma de vesícula y posterior a traumatismo. Su presentación clínica es variable, pudiendo presentar afección sistémica, y su sitio más frecuente de drenaje externo es en hipocondrio derecho. Debido a la baja incidencia de esta afección, y a la variedad de formas de presentación, su manejo no tiene hasta el momento bases estandarizadas. Presentamos dos casos de pacientes que consultaron por guardia de urgencias en el Hospital Nacional de Clínicas por presentar fistula colecisto-cutánea. El tratamiento de ambos fue quirúrgico.

Endoscopic stent placement for the management of gastro-pleural and gastro-cutaneous fistula post laparoscopic sleeve gastrectomy: a case report.

BACKGROUND: Gastro-pleural and gastro-cutaneous fistulae formation are rare yet life-threatening complications post-bariatric surgery. To our knowledge so far only limited cases of gastro-pleural and gastro-cutaneous fistulae post gastric sleeve surgery have been reported in the literature with their corresponding management. Therefore, we are reporting a case of placement of an endoscopic stent in the management of gastro-cutaneous fistula post laparoscopic sleeve gastrectomy. CASE PRESENTATION: A 42 years old Pakistani, female morbidly obese patient, underwent laparoscopic sleeve gastrectomy. Within a week after the procedure, the patient presented with dyspnea. Workup showed a gastric leak for which percutaneous drain placement was done. Later, gastro-pleural and gastro-cutaneous fistulae were formed for which endoscopic fistula closure was done using a metallic stent. CONCLUSION: Endoscopic stent placement is an emerging field and it is considered safe and effective for the management of complications related to bariatric surgery.

Closure of Gastrocutaneous Fistula Following Bariatric Surgery: a Systematic Review.

Gastrocutaneous fistula (GCF) is a devastating complication that can arise after bariatric and metabolic surgery (BMS). This systematic review examines the success rate of closure techniques of GCF. A systematic search was conducted across MEDLINE, Embase and Cochrane databases to identify studies which reported on closure techniques of GCF after BMS in adults. Thirty-three studies (n = 108 patients) were included. Seventeen different techniques were used to close GCF across all studies. The most popular were stents (n = 17), tissue sealants (n = 12) and over-the-scope clips (n = 11). Twenty-one studies used multiple techniques to attempt closure, including endoscopic vacuum therapy and revisional surgery. This systematic review demonstrates current practice focusing on endoscopic methods such as stents and over-the-scope clips, with relative success in closing GCF.

A review of pharyngocutaneous fistula management in head and neck malignancies.

Pharyngocutaneous fistula is a serious complication after head and neck reconstruction and concurrent chemoradiotherapy, yet no consensus or practical protocols regarding the surgical timing and specific procedures could be found in the current literature. The authors aimed to review their clinical experience in surgical management and develop an algorithmic approach accordingly. A retrospective review of all hypopharyngeal cancer patients who developed pharyngocutaneous fistula during 2017 to 2021 at E-Da Hospital was conducted. Seventeen patients developed pharyngocutaneous fistula in all 321 pharyngeal cancer admissions during this period. Three patients received interventions at acute stage (≤2 weeks), with two direct repairs Three patients received interventions at acute stage (≤2 weeks), with two direct repairs and one regional flap coverage then negative pressure wound therapy. Nine received interventions at subacute stages (2 weeks to 3 months), with 4 resolved after debridement and direct repair yet another 4 underwent regional flap reconstruction and 1 free flap reconstruction. Five chronic fistula (>3 months) received secondary reconstructions utilizing a double-layered repair of local turn-over flaps for the internal mucosal opening and another flap harvest (four regional flaps and one free flap) to cover the outer skin defect. All patients after the palliative surgery achieved complete remission of fistula at follow follow-up. Different conservative and surgical approaches should be adopted according to the acute, subacute, and chronic stages of pharyngocutaneous fistula after palliative head and neck reconstructions.

Staged neck dissection prior to transoral robotic surgery for oropharyngeal cancer: does it reduce post-operative complication rates? A multi-centre study of 104 patients.

PURPOSE: Transoral robotic surgery (TORS) has become increasingly recognised as a safe and effective treatment for early oropharyngeal squamous cell carcinoma, often performed in conjunction with neck dissection (ND) and vessel ligation. It has been proposed that performing the neck dissection in a staged fashion prior to TORS results in low rates of transoral haemorrhage and pharyngocutaneous fistula, and may aid in TORS patient selection by eliminating patients who would require multi-modality treatment based on nodal pathology. This study aims to assess the effect of staged neck dissection with TORS in mitigating pharyngocutaneous fistulae and post-operative haemorrhage as well as the impact of staged ND on TORS patient selection. METHODS: A retrospective cohort analysis was performed of patients undergoing staged ND with intent to proceed to TORS at two Australian hospitals between 2014 and 2022. Incidence of post-operative haemorrhage and pharyngocutaneous fistula and length of inpatient stay was identified. The number of patients who did not proceed to TORS was recorded. RESULTS: One hundred and four patients were identified who underwent staged neck dissection with an intention to proceed to TORS. Six patients did not proceed to TORS following pathological assessment of the neck dissection specimen and ninety-eight patients (91 primary, 7 salvage) underwent TORS. There were six cases of secondary haemorrhage (one major, two intermediate and three minor). There were no cases of pharyngocutaneous fistula. CONCLUSION: Staged neck dissection prior to TORS results in low rates of haemorrhage and pharyngocutaneous fistula and can improve TORS patient selection.

Gastrostomy dependence following pharyngolaryngectomy: The effect of preoperative tube insertion.

BACKGROUND: The aim of this study is to investigate the impact of preoperative gastrostomy in patients undergoing pharyngolaryngectomy (PL) on gastrostomy tube dependence at 6 months postoperatively. METHODS: A retrospective review of patients undergoing PL for laryngeal squamous cell carcinoma between 2005 and 2019 was performed. Parameters were collected and analyzed within the multivariate models. RESULTS: Ninety-three patients (82% male, mean age 63.4 [SD 9.4]) were included. Preoperative tube placement and pharyngocutaneous fistula (PCF) were associated with an increased likelihood of gastrostomy tube dependence at 6 months (odds ratio 6.43, CI 1.1-38.3, p = 0.041) after adjusting for multiple confounding factors. There was no difference in the incidence of delayed oral feeding, PCF, or hospital stay between the groups. CONCLUSIONS: Preoperative tube and PCF are associated with an increased likelihood of tube dependence at 6 months. Patients for preoperative tube insertion should be carefully selected and early oral feeding reintroduction should be encouraged.

Pyelonephritic end-stage kidney and ureterocutaneous fistula in a Shetland pony.

A 12-y-old Shetland Pony was presented with a mucus-secreting fistula in the right paralumbar fossa. Surgery was performed to unravel the origin of the fistula. The horse died under anesthesia and was forwarded to autopsy. The right kidney was markedly atrophic and fibrotic, consistent with unilateral end-stage kidney. The right ureter was markedly thickened, but with luminal continuity leading into the urinary bladder where a partial obstruction caused by nodular para-ureteral fat necrosis was evident. The lumen of the cutaneous fistula was continuous with the right ureter; therefore, we diagnosed the lesion as a ureterocutaneous fistula. Anomalies of the ureter are uncommon, and ureterocutaneous fistula formation in equids has not been reported previously to our knowledge.
