Endoscopic endoluminal therapy with the Eso-SPONGE® system for the treatment of spontaneous esophageal perforation with associated paraoesophageal collection.

We present the case of a 92-year-old woman with no relevant history, who consulted for sore throat, progressive dysphagia to solids and fever. A cervical-thoraco-abdominal CT was performed with the finding of a paraesophageal collection at the level of C3-T1 without a clear solution of continuity, although with passage of oral contrast to the collection, exerting a mass effect on the esophageal lumen, suggestive of contained esophageal perforation, of cause not clarified. A gastroscopy was performed, in which three esophageal fistulous orifices were observed, two 4-5 mm, and a third 10 mm deeper, located 22cm from the dental arch, septate, with perilesional purulent material and bubbling.

Upper gastrointestinal bleeding secondary to late gastric metastasis of renal cell carcinoma.

Clear cell renal cell carcinoma is the most common renal neoplasm in adults. It has a relatively slow growth pattern that delays diagnosis until the onset of local, paraneoplastic or metastasis-related manifestations, and an unpredictable behavior ranging from aggressive tumors with poor short-term prognosis to late recurrence cases where metastases are identified years after nephrectomy, the latter scenario being the subject of the case we herein report.

Ethmoidal metastasis as an uncommon presentation and diagnostic form of hepatocellular carcinoma.

Nasopharynx metastases are an extremely rare cause of hepatocarcinoma debut. We report the case of a 71 year old man who presented symptoms of nosebleed and diplopia event, diagnosed by imaging and biopsy of ethmoidal metastasis of hepatocarcinoma.

Diagnosis of biliary papillomatosis with a Spyglass® cholangioscope.

We report the case of a 78-year-old woman with dyspepsia for several years and a history of cholecystectomy, informed by pathology as calculous cholecystopathy, where CT revealed a left-sided intrahepatic bile duct dilation. Cholangio-MRI confirmed a size increase in the distal intrahepatic bile duct on the left side, with T2-hyperintense contents with scarce contrast enhancement, which resulted in the observed dilation. . A Spybite® forceps was used to obtain a biopsy sample, which showed a benign papillary growth compatible with biliary papillomatosis. Biliary papillomatosis or intraductal papillary neoplasm of the biliary tract is a rare, uncommon condition characterized by intraductal papillary growth of the biliary epithelium. It has a tendency towards malignization, hence must be considered a premalignant condition . Major symptoms include jaundice, abdominal pain, and repeat cholangitis, with imaging studies being key for diagnostic suspicion . The development of cholangioscopy with biopsies allows an early diagnosis of malignant precursor lesions of the bile duct, thus allowing early treatment.

Endoscopic submucosal dissection of gastric plexiform fibromyxoma, an alternative to the traditional approach.

We report the case of a 62-year-old woman with no history of interest who presented with dyspepsia of 2 years' standing. Gastroscopy revealed a subepithelial lesion at the greater antral curvature with irregular surface and preserved mucosal and vascular pattern, 15 mm in diameter. Because of clinical persistence a radial endoscopic ultrasonogram (EUS) was performed, which showed a well-delimited hypoechoic lesion with heterogeneous areas that was dependent on the muscularis mucosae layer. A biopsy was obtained using the "bite-on-bite" technique, which provided no pathological findings. With these findings an endoscopic submucosal dissection (ESD) procedure was performed with wide margins and no complications. Pathology found low-grade mesenchymal fusicellular proliferation dependent on the muscularis mucosae with immunohistochemistry positive for smooth-muscle vimentin and actin, consistent with plexiform fibromyxoma.

Mucinous ascites secondary to peritoneal pseudomyxoma of an uncertain origin.

Peritoneal pseudomyxoma (PP) is a rare malignant tumor, which is characterized by the presence of mucinous ascites. Abdominal ultrasound as the first diagnostic method of this entity allows the visualization of ascites on the one hand and its analysis through a diagnostic paracentesis on the other.

Active search for hepatitis C patients in primary care.

INTRODUCTION: undiagnosed active hepatitis C virus (HCV) infections are an obstacle to achieve the WHO (World Health Organization) hepatitis C elimination goal by 2030. One of the possible strategies to identify these patients is the active search for patients in primary care (PC). METHODS: patient medical records in PC were reviewed with a "hepatitis C" open case in the last five years. Cases with an incomplete diagnostic study (due to the absence of active infection confirmation) or those who did not start or finish treatment were included. A blood analysis was recommended to prove the existence of an active infection. The one-step diagnosis (OSD) was implemented to assess viremia in all patients with a new serologic diagnosis. RESULTS: of 253 cases with a "hepatitis C" open case in their medical records, 24.1 % (61) did not finish the diagnostic study or did not follow the treatment. Four were not suitable candidates to finish the study. Of the other 57, 92.9 % accepted the diagnostic test. Active infections were confirmed in 40 patients (75.4 %) and the treatment was completed in all of them. CONCLUSIONS: active searching for patients with hepatitis C in PC together with the OSD are effective measures to detect hidden infections and to increase the number of treatments, thus contributing to the elimination of hepatitis C.

Porcine experimental model for perforator flap raising in reconstructive microsurgery.

BACKGROUND: Perforator free flap-based reconstruction of the head and neck is a challenging surgical procedure and needs a steep learning curve. A reproducible mammal large animal model with similarities to human anatomy is relevant for perforator flap raising and microanastomosis. The aim of this study was to assess the feasibility of a swine model for perforator-based free flaps in reconstructive microsurgery. METHODS: Eleven procedures were performed under general anesthesia in a porcine model, elevating a skin flap vascularized by perforating musculocutaneous branches of the superior epigastric artery to evaluate the relevance of this model for head and neck reconstructive microsurgery. RESULTS: The anterior abdominal skin perforator-based free flap in a swine model irrigated by the superior epigastric artery was elevated in eleven procedures. In six of these procedures, we could perform an arterial and venous microanastomosis to the great vessels located in the base of the neck. CONCLUSIONS: The porcine experimental model of superior epigastric artery perforator-based free flap reconstruction offers relevant similarities to the human deep inferior epigastric artery perforator flap. We could demonstrate this model as acceptable for perforator free flap training due to the necessity of perforator and pedicle dissection and transfer to a distant area.

Hypersplenism secondary to splenoportal axis compression by a giant hepatic cyst.

Simple hepatic cysts (SHCs) are formations that contain serous fluid surrounded by normal hepatic parenchyma with no communication with intrahepatic bile ducts. Symptoms develop as a result of their size or complications such as bleeding, rupture, intracystic infection or compression of adjacent structures.

Autologous Tragal Perichondrium Graft for Vocal Fold Scar and Sulcus Vocalis.

Between 2006 and 2016 in a Tertiary Academic Center, 11 patients underwent phonomicrosurgery with tragal perichondrium graft placement in Reinke's space for the treatment of sulcus (Ford type 2) and vocal fold scar. A total of six patients out of 11 had an additional autologous fat implantation in order to improve the glottic closure. We evaluated the functional outcome using the Spanish validated version of the VHI- 30 before and 6 months after the surgery. We also measured the subjective appreciation of the obtained outcome, a perceptual voice evaluation using GRBAS scale, and changes in videostroboscopy examinations concerning mucosal wave and glottic closure. In the VHI-30 questionnaire, we observed an improvement in all patients (six of which showed an improvement of 50% or more) with statistically significant results (P = 0.003), and no significant differences between sulcus (Ford type 2) and vocal cord scar patients (P = 0.7579). The results obtained from the single question assessing changes in voice quality showed a high improvement in seven patients. According to the GRBAS scale, all cases improved. Concerning the results of the videostroboscopy, two patients obtained very favorable results, eight of them presented a moderate recovery and only one improved slightly. The following complications were identified: two granulomas, a graft extrusion and a tragal infection. The tragal perichondrium used as an autograft in Reinke's space appears to be a safe and satisfactory choice, comparable to other grafts such as temporalis fascia or autologous fat.

Reconstruction using facial artery system-based flaps. One vascular system for multiple purposes in head and neck reconstructive surgery. / Reconstrucción mediante colgajos basados en el sistema de la arteria facial. Un sistema vascular para múltiples usos en cirugía reconstructiva de cabeza y cuello.

INTRODUCTION: to review the modifications and advances in reconstructive surgery of the soft tissues of the oral cavity exclusively based on flaps that depend on the facial artery system. METHODS: review of the literature regarding oral cavity reconstructions based on main facial artery system flaps. DISCUSSION: The reconstruction of the soft tissues of the oral cavity, based on facial artery system flaps, offers satisfactory results and allows limited reconstructions avoiding the use of pedicled regional flaps or free flaps. CONCLUSIONS: Knowledge of reconstructive options using the facial artery system in oral cavity surgery allows expanding reconstructive options for head and neck surgeons, enabling safe, high quality and effective reconstructions, with limited resources consumption.

Porcine experimental model for gracilis free flap transfer to the head and neck area with novel donor site description.

INTRODUCTION: Functional free tissue transfer in the form of muscle free flap is a challenging surgical procedure and needs a steep learning curve. A porcine model for free muscle transfer and insetting in a distant area is of great interest in reconstructive microsurgery due to the experience and learning curve necessary to perform these surgeries. The aim of this study was to assess the feasibility of a swine model for gracilis muscle free transfer and to describe the donor site anatomy. METHODS: Ten gracilis free flap transfer surgery models were performed under general anesthesia in a porcine model, based on a vascular pedicle depending of the external iliac vessels and a branch of the obturator nerve with microsuture mediated connection to head and neck nerves and vessels. RESULTS: The gracilis myocutaneous or muscle-only free flap was successfully transferred in all cases using as receptors the vagus nerve, the common carotid artery, and the external or internal jugular veins. In two cases, nervous connection had to be redone. All vascular anastomoses were correctly functioning. CONCLUSIONS: Despite the anatomical and design variations, porcine gracilis free flap transferred to the head and neck area with microvascular anastomosis and nerve connection provides a suitable training model for functional reconstructive microsurgery.

Application of flexible endoscopy-based biopsy in the diagnosis of tumour pathologies in otorhinolaryngology. / Aplicación de la biopsia por endoscopia flexible en el diagnóstico de la patología tumoral en otorrinolaringología.

INTRODUCTION AND OBJECTIVES: Interventional endoscopy allows us to act on the pathology of the patient with minimal discomfort, low costs and high efficiency. We assessed the validity of flexible endoscopic biopsies in our hospital, in lesions suspected of malignancy in the rhino-pharyngo-laryngeal space. SUBJECTS AND METHODS: Retrospective study of patients with a pathology suspected of malignancy assessed between 2006-2016 in our centre. We evaluated the effectiveness, the tolerance and the number of complications. We calculated the cost reduction in comparison with direct laryngoscopy in the operating room. We compared our sample with others of similar characteristics described in the literature. RESULTS: Thirty patients were studied with a flexible endoscopic biopsy during that period. Nineteen patients obtained positive results which allowed them to start treatment for their pathology. Seven cases had no evidence of malignancy and required another biopsy under general anaesthesia, which confirmed the carcinoma diagnosis. Two samples ruled out malignancy which was confirmed by laryngeal microsurgery. One case showed inflammation and the lesion was cured after antibiotherapy. It was impossible to collect the sample in one case. Thus, we obtained sensitivity levels of 73% with a specificity of 100%. There were no complications. The cost reduction in our sample was above 80%. CONCLUSIONS: Flexible endoscopic biopsy has advantages over direct laryngoscopy that are relevant in the diagnosis of oncological pathology in otorhinolaryngology.

Utility and versatility of the supraclavicular artery island flap in head and neck reconstruction. / Utilidad y versatilidad del colgajo en isla de la arteria supraclavicular en reconstrucción de cabeza y cuello.

INTRODUCTION: The supraclavicular island flap is a rotational pedicled flap and may have some advantages in head and neck reconstruction compared with free-tissue transfer when this kind of reconstruction is not affordable or recommended. MATERIAL AND METHODS: We present our experience during the year 2016 in the application of the supraclavicular island flap in five cases as an alternative to microvascular reconstruction in several defects after resection of head and neck tumours. In two patients, the flap was used to close the surgical pharyngostoma after total laryngectomy with partial pharyngectomy. In one patient, it was used in lateral facial reconstruction after partial resection of the temporal bone. In one case, it was used to close a skin defect after total laryngectomy with prelaryngeal tissue extension. And in the last case to close a neck skin defect after primary closure of a pharyngo-cutaneous fistula. There were no flap complications, and the result was satisfactory in all cases. RESULTS: The supraclavicular artery island flap is useful and versatile in head and neck reconstruction. Operating room time in aged patients or those with comorbidities will be reduced compared to free flaps. The surgical technique is relatively easy and can be used for skin and mucosal coverage. CONCLUSION: The supraclavicular island flap could be a recommended option in head and neck reconstruction, its use seems to be increasing and provides a safe and time-saving option to free flaps in selected patients.

A review of our experience in phonosurgery in children. / Revisión de nuestra experiencia en fonocirugía infantil.

INTRODUCTION AND OBJECTIVES: Dysphonia is a common problem in children, especially those of school age. Exploration of vocal folds is often difficult and less accurate in children. The most frequent lesions found in children with chronic dysphonia are vocal nodules, followed by epidermoid cysts and other congenital lesions, such as sulci and mucosal bridges. The treatment is multidisciplinary and it is fundamentally based on vocal rehabilitation. We indicate surgical treatment in children older than 9 years of age for whom the problem persists after rehabilitation, especially if we suspect a congenital lesion of the vocal fold. METHODS: We present a retrospective study of paediatric phonosurgery performed by the Vocal Pathology Unit of our Hospital over a period of 9 years (2005-2013). Fifty-one children were included, ranging in age from 9 to 16 years old. We analyzed the distribution of the different lesions, both congenital and acquired. We evaluated the results by subjective evaluation by the children's relatives. RESULTS: We obtained a distribution of 76% (n=39) of congenital lesions and 24% (n=12) of acquired lesions. After surgery, there was a global percentage of improvement of 90%, with better results in cases of vocal nodules, without statistical significance. CONCLUSIONS: The evaluation of the results of this surgery is controversial and in this study is done with a single question survey administered to relatives. We found an overall result of improvement in 90% of operated cases, without any complications. We obtained better results in vocal nodules, although not reaching statistical significance.

Change in tinnitus after acoustic neuroma removal using a translabyrinthine approach. A Prospective study. / Estudio prospectivo de la evolución del acúfeno tras exéresis por vía translaberíntica del neurinoma del acústico.

INTRODUCTION: Tinnitus is one of the primary symptoms of vestibular schwannoma (VS) and the effect of surgery is unpredictable. MATERIALS AND METHODS: We conducted a prospective study of the patients who underwent a translabyrinthine approach for the treatment of their VS (2009-2013) at our Hospital. Patients answered the Tinnitus Handicap Inventory (THI) questionnaire pre- and postoperatively. The clinical charts provided data such as age, gender, tumour size, preoperative audiometry and postoperative facial function. RESULTS: The study included 39 patients. Of these, 71.8% suffered from tinnitus: 50% grade I, 17.9% grade II, 10.7% grade III, 21.4% grade IV and 0% grade V. We found no statistical association between tinnitus and the different variables measured preoperatively. Postoperatively, 48.7% of the patients suffered from tinnitus: 31.6% grade I, 36.8% grade II, 10.5% grade III, 15.8% grade IV and 5.3% grade V. The difference between mean pre- and postoperative THI was statistically significant (P=.011); this difference was greater in younger patients. We have found a significant negative correlation (r=-0.335; P=.037) between preoperative audiometry and postoperative THI. CONCLUSIONS: We did not find any significant association between tinnitus and age, gender, tumour size and postoperative facial function. Translabyrinthine surgical removal of VS in these patients led to better THI results, with the younger patients having better outcomes. The patients with poorest preoperative audition were the ones that had the best results in the postoperative THI questionnaire.

Bone-anchored hearing device surgery: Linear incision without soft tissue reduction. A prospective study.

INTRODUCTION AND OBJECTIVES: The classic surgical procedure for percutaneous bone-anchored hearing devices involves removal of a large area of subcutaneous tissue down to the periosteum. This leads to alopecia and raises the risk of devascularization of the overlying skin with the potential for infection and scarring. The objective of this study was to determine the results of implant placement using a single, linear incision with no underlying soft tissue reduction. MATERIAL AND METHOD: A prospective study was conducted in our hospital over a period of 14 months in all consecutive surgeries performed using this technique in adults. Patients were reviewed regularly (week 1, week 3, weeks 4-6 and months 3, 6 and 12) to assess wound healing including evaluation with the Holgers scale. RESULTS: Corresponding to 34 patients, 34 cases were consecutively enrolled in this study. We found that 15% of the patients had minor skin reactions during the first visit (Holgers grade 1 or 2); this number raised to 20% in week 3, but at week 4 only 1 patient had a reaction score of 1 (which was solved by week 6). None of the cases required revision surgery and all skin reactions were treated topically. CONCLUSIONS: Our results suggest that the tissue preservation technique is a simple and effective insertion technique with a favourable healing process and cosmesis.

Aplicación de la biopsia por endoscopia flexible en el diagnóstico de la patología tumoral en otorrinolaringología / Application of flexible endoscopy-based biopsy in the diagnosis of tumour pathologies in otorhinolaryngology

Introducción y objetivos: La endoscopia intervencionista nos permite actuar sobre la patología del paciente con mínimas molestias, bajos costes y alta eficiencia. Evaluamos la validez de la biopsia por endoscopia flexible en nuestro hospital, en las lesiones sospechosas de malignidad en el espacio rinofaringolaríngeo. Material y método: Estudio retrospectivo de los pacientes con patología sospechosa de malignidad valorados en el periodo 2006-2016 en nuestro centro. Valoramos la eficacia, la tolerancia y número de complicaciones. Calculamos la reducción de costes frente a la laringoscopia directa en quirófano. Comparamos nuestra muestra con otras de características similares descritas en la bibliografía. Resultados: Treinta pacientes fueron estudiados mediante biopsia por endoscopia flexible en ese período. Diecinueve pacientes obtuvieron resultados positivos que permitieron iniciar el tratamiento de su patología. Siete casos, sin evidencia de malignidad, requirieron nueva biopsia bajo anestesia general que confirmó el diagnóstico de carcinoma. Dos muestras descartaron malignidad, dato que se confirmó tras microcirugía de laringe. Un caso mostró inflamación y la lesión se resolvió tras antibioterapia. En un caso la toma de muestra resultó imposible. Obtenemos de esta forma niveles de sensibilidad del 73% con una especificidad del 100%. No se produjeron complicaciones. La reducción de costes en nuestra muestra fue superior al 80%. Conclusiones: La biopsia por endoscopia flexible aporta ventajas sobre la laringoscopia directa que resultan de interés en el diagnóstico de patología oncológica en otorrinolaringología (AU)
