[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.

La lesión quirúrgica de la vía biliar es una complicación peligrosa de la colecistectomía, con importantes secuelas postoperatorias para el paciente en términos de morbilidad, mortalidad y calidad de vida. Tienen una incidencia laparoscópica estimada del 0,4% al 1,5% y del 0,2% al 0,3% en la colecistectomía convencional. El objetivo de este estudio fue evaluar la incidencia de LQVB durante la formación del cirujano y la importancia de realizar colangiografía intraoperatoria (COI) durante esta etapa

Bile duct surgical injury is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality and quality of life. These have an estimated laparoscopic incidence of 0.4% to 1.5% and 0.2% to 0.3% in conventional cholecystectomy. The aim of this study was to evaluate the incidence of LQVB during surgeon training and the importance of performing intraoperative cholangiography (IOC) during this stage

[Ceccum leiomyoma: an unusual cause of intestinal occlusion in adults] / Leiomioma de ciego: una causa inusual de oclusión intestinal en adultos.

Introduction: Cecal leiomyoma is a very rare benign tumor of the colon, constituted by a proliferative process of smooth muscle that originates from the muscularis propria or the muscularis of the cecum mucosa. These are often asymptomatic tumors that are found incidentally during screening studies or in the context of some other pathology. In cases with clinical expression, it commonly presents as chronic abdominal pain or a palpable abdominal mass. Infrequently it manifests as complications such as intestinal perforation, intestinal bleeding, or intestinal obstruction that require surgical treatment. Method: We present the case of a 25-year-old woman who came to the Central Guard service of the institution for abdominal colic pain of 48 hours of evolution associated with vomiting and abdominal distention. The videolaparoscopic surgical approach was decided in which an abdominal mass was identified at the level of the ileoceccal valve. Conventional right hemicolectomy with proximal loop ileostomy was performed with good postoperative evolution. Histopathological examination of the resected specimen revealed a benign ceccum leiomyoma. Results: The patient resolved her acute abdominal symptoms without complications and was discharged on the 5° postoperative day. Conclusion: The scarcity of studies and bibliography related to this infrequent pathology denotes the need to elaborate new studies of greater scope that offer answers to the questions and controversial aspects that still persist in relation to the clinical, diagnostic and therapeutic management of benign cecal tumors of mesenchymal lineage.

Introducción: El leiomioma cecal es un tumor benigno del colon, muy raro, constituido por un proceso proliferativo de músculo liso que se origina a partir de la muscularis propia o la muscularis de la mucosa del ciego. Con frecuencia se trata de tumores asintomáticos que se encuentran de forma incidental durante los estudios de detección o en el contexto de alguna otra patología. En los casos con expresión clínica, comúnmente se presentan con dolor abdominal crónico o masa abdominal palpable. Infrecuentemente debutan con complicaciones como perforación intestinal, sangrado intestinal u obstrucción intestinal que requieren tratamiento quirúrgico.Método: Presentamos el caso de una mujer de 25 años que acude al servicio de Guardia Central de la institución por dolor cólico abdominal de 48 horas de evolución asociado con vómitos y distensión abdominal Se decidió el abordaje quirúrgico videolaparoscópico en el que se identifico una masa abdominal a nivel de la válvula ileoceccal. Se realizó hemicolectomía derecha convencional con Ileostomía en asa proximal con buena evolución post operatoria. El examen histopatológico de la pieza resecada reveló un leiomioma benigno de ciego. Resultados: La paciente resolvió su cuadro abdominal agudo sin complicaciones y fue dada de alta al 5° día post-operatorio. Conclusión: La escasez de estudios y bibliografía relacionados con esta infrecuente patología denota la necesidad de elaborar nuevos estudios de mayor alcance que ofrezcan respuestas a los interrogantes y aspectos controvertidos que aún persisten en relación al manejo clínico, diagnóstico y terapéutico de los tumores cecales benignos de estirpe mesenquimal.

Apendicitis aguda y el riesgo de tumor maligno oculto. Presentación de un caso y revisión sistemática de la literatura / Acute appendicitis and the risk of hidden malignant tumor. Presentation of a case and systematic review of literature

Introducción: Los tumores apendiculares representan aproximadamente 1% de los tumores malignos del intestino grueso. Más del 50% de las neoplasias primarias del apéndice se manifiestan inicialmente como apendicitis aguda. Métodos: Se reporta caso de paciente masculino que presentó adenocarcinoma invasor en biopsia de pieza quirúrgica de apéndice cecal tras apendicectomía, tomando la decisión de realizar hemicolectomía derecha laparoscópica diferida. Discusión: En este caso y como en la mayoría de los reportes de la bibliografía mundial, el adenocarcinoma simula un cuadro de AA. En un metaanálisis y una revisión sistemática de 2.771 pacientes diagnosticados de masa apendicular inflamatoria (flemón o absceso), Andersson et al. encontró 31 con tumores malignos. Estas lesiones se detectan en el 0,9% al 1,4% de las apendicectomías realizadas para tratar la AA. Conclusión: Este subtipo histológico presenta mayor incidencia de metástasis en los ganglios linfáticos y la supervivencia global era del 47,5%. Es por ello por lo que abogamos por la resección colónica como tratamiento definitivo del adenocarcinoma de apéndice cecal.

INTRODUCTION: Appendulular tumors represent approximately 1% of malignant tumors of the large intestine. More than 50% of the primary neoplasms of the appendix initially manifest as acute appendicitis. Methods: Men's patient who presented invading adenocarcinoma in Cecal Appendix Surgical Party Biopsy after appendectomy, making the decision to perform deferred laparoscopic right hemicolectomy, is reported. Discussion: In this case and as in most world literature reports, adenocarcinoma simulates an AA picture. In a meta -analysis and a systematic review of 2,771 diagnosed patients of inflammatory appendicular mass (phlegmon or abscess), Andersson et al. He found 31 with malignant tumors. These lesions are detected at 0.9% to 1.4% of appendectomies made to treat the AA. Conclusion: This histological subtype has a greater incidence of metastasis in lymph nodes and global survival was 47.5%. That is why we advocate colonic resection as a definitive treatment of cecal appendix adenocarcinoma.

[Usefulness of the Difficult Cholecystectomy Score according to laparoscopic conversion]. / Utilidad del Score de la Colecistectomía Dificultosa según conversión laparoscópica.

Introduction: Biliary lithiasis (LB) is a very frequent problem in the daily consultation of a general surgeon, so currently, 10 to 15% of the adult population in the experienced countries has LB. Methodology: A descriptive, observational and cross-sectional study was carried out with patients sometimes having a laparoscopic cholecystectomy in a period between January 1, 2018 and December 31, 2018. The main objective of this study is to determine the differences in the risk scoring means of difficult cholecystectomy according to the conversion to open surgery in patients diagnosed with symptomatic biliary lithiasis. Results: Through the registered data, it can be said that being a man, with a leukocyte count> 12,000 mm3, with a BMI> 30, the presence of choledocholithiasis and a greater gallbladder cut with 3 mm are factors that increase the risk of conversion to open surgery in this series of patients. It is feasible and safe to use this score to determine the patients with the highest risk of conversion since all the independent factors identified are not modifiable. Conclusion: In short, being a man, with a leukocyte count> 10,000 mm3, with a BMI> 30, the presence of choledocholithiasis and a gallbladder wall greater than 3 mm are factors that increase the risk of conversion to open surgery in a series of patients undergoing video laparoscopy. in a university hospital and it is feasible and safe to use this score to identify those patients with the highest risk of conversion.

Introducción: La litiasis biliar (LB) es un problema muy frecuente en la consulta diaria de un cirujano general, por lo que actualmente, del 10 al 15% de la población adulta en los países desarrollados presenta LB. Metodología: Se realizó un estudio descriptivo, observacional y transversal con los pacientes sometidos a colecistectomía laparoscópica en un período comprendido entre el 1 de enero del 2018 y el 31 de diciembre del 2018. El objetivo principal de este estudio es determinar diferencias de media del score de riesgo de colecistectomía dificultosa según conversión a cirugía abierta en pacientes con diagnóstico de litiasis biliar sintomática. Resultados: A través de los datos registrados se puede decir que ser hombre, con recuento de leucocitos >12.000 mm3, con IMC >30, presencia de coledocolitiasis y pared vesicular mayor a 3 mm son factores que incrementan el riesgo de conversión a cirugía abierta en esta serie de pacientes. Es factible y seguro utilizar este score para determinar aquellos pacientes con mayor riesgo de conversión dado que todos los factores independientes identificados no son modificables. Conclusión: En definitiva, ser hombre, con recuento de leucocitos >10.000 mm3, con IMC >30, presencia de coledocolitiasis y pared vesicular mayor a 3 mm son factores que incrementan el riesgo de conversión a cirugía abierta en una serie de pacientes sometidos a video laparoscopía en un Hospital universitario y es factible y seguro utilizar este score para identificar esos pacientes con mayor riesgo de conversión.

Lugar de aplicación: Hospital Nacional de Clínicas y Clínica privada. Diseño: Estudio protocolizado y prospectivo. Material y método: Entre diciembre 2000 y diciembre 2014 se operaron 96 DPC. Las indicaciones de la cirugía fueron: 39 cánceres de la cabeza de páncreas, 19 cánceres de papila, 9 cáncer de duodeno, 10 de colédoco distal, 5 tumores quísticos del páncreas, 4 pancreatitis crónica, 3 tumores funcionantes de páncreas, 3 tumores no funcionantes, finalmente 3 tumores de otra etiología. Resultados: Con respecto a la mortalidad dentro de los 30 días, fallecieron 5 pacientes (4, 80 %). Posteriormente, fallecieron dentro de los 90 días 5 pacientes más (9,3 %). En las complicaciones quirúrgicas, nosotros encontramos: la fistula pancreática hubo en 32 pacientes. Con respecto al Vaciamiento gástrico estuvo presente en 19 enfermos y finalmente en 5 pacientes tuvieron una hemorragia intra peritoneal que fueron re intervenidos y uno de los cuales falleció. Por otro lado, hubo 11 colecciones abdominales, donde se re operaron 4 pacientes y a los 7 restantes se les colocó un drenaje en dicha colección. Se re intervinieron 4 pacientes con evisceración, CONCLUSIONES: Los resultados de nuestro trabajo, apoyan el concepto que cirujanos con bajo volumen de D.P.C. anuales, pero con una estricta formación en Instituciones con infraestructura adecuada y un equipo multidisciplinario, pueden también obtener buenos resultados en las lesiones malignas y benignas del confluente bilio-duodeno-pancreático

Background: Cephalic duodenopancreatectomy (CDP) (pancreaticoduodenectomy of the head of the pancreas) is the surgical option accepted as the procedure of choice for the management of both malignant and benignant tumours of the duodenal-pancreatic biliary confluence. Setting: National Clinical Hospital and private practice. Desing: Protocoled and prospective study. Methods: Between December 2000 through December 2014, 96 CDP have been operated upon: 39 cancers of the head of the pancreas, 19 cancers of the papilla, 9 cancers of the duodenum, 10 of the distal common bile ducts, 5 cystic tumours of the pancreas, 4 chronic pancreatitis, 3 functioning pancreas, 3 non-functioning tumours, and finally 3 tumours of different ethiologies: 1 GIST of duodenum, 1 metastasis from a renal cancer, and 1 colon cancer of the hepatic flexure who invaded the duodenum. Results: Pancreatic fistulas were observed in 32 patients. With reference to gastric emptying it was present in 19 patients, and finally in 5 patients an intra peritoneal haemorrhage was present which were re- intervened, and one of them died. On the other hand, 11 abdominal collections were present, of whom 4 patients were re-operated, and to the remaining 7 ,a drainage was placed in the collection. Four patients were re-operated with evisceration. Conclusions: The results of our study support the concept that surgeons with low volume of annual CDP, but with strict training in institutions with adequate infrastructure and a multidisciplinary team, can obtain also good results.

[Minimally Invasive Video-assisted Thyroidectomy. Experience the same working group] / Tiroidectomía mini-invasiva videoasistida.

Different thyroidectomy techniques have been developed to improve the aesthetic results, postoperative pain and to reduce hospital stay. Objective: To demonstrate the feasibility, safety and efficacy of minimally invasive video-assisted thyroidectomy (MIVAT). Design: Retrospective Methods: Ninety six patients with thyroid nodules were selected for MIVAT if they presented nodules under 35 mm in diameter, thyroid volume below 30 ml and absence of high-risk malignant tumor, lateral cervical lymphadenopathy or prior cervical surgery. Indirect laryngoscopy was performed before and after surgery to all patients. Surgery was performed through a midline incision of 1.5 cm above the sternal notch, without carbon dioxide and with magnification endoscopy. We evaluated postoperative complications, pain after surgery, the cosmetic outcome and length of stay. Results: Ninety patients underwent total thyroidectomy or near-total thyroidectomy. The average operative time was 54 ± 9 minutes. The average diameter of the nodule was 20 ± 6 mm. The average volume was 19 ± 6 ml. We documented six (6.2%) hyperparathyroidism and one recurrent laryngeal nerve palsy (0.96%), both transient and none of them permanent. The postoperative pain was minimal and all patients were discharged within 24 hours. Conclusion: In our experience the MIVAT is a safe and feasible technique for the treatment of thyroid disease, with clear advantages over conventional thyroidectomy in selected patients. Conclusion: In our experience the MIVAT is a safe and feasible technique for the treatment of thyroid disease, with clear advantages over conventional thyroidectomy in selected patients.

[Primary Hyperthyroidism. Minimally invasive video-assisted parathyroidectomy] / Hiperparatiroidismo primario. Paratiroidectomia miniinvasiva videoasistida

Objective: Show our experience performing the minimally invasive video-assisted parathyroidectomy with central approach for the treatment of patients with primary hyperparathyroidism without using intraoperative parathyroid hormone monitoring (IPTHM) based solely on the concordance of two preoperative localization studies. Material and methods: An informed consent for the accomplishment of a minimally invasive approach was performed on 27 selected patients diagnosed with primary hyperparathyroidism who underwent pre-operative cervical ultrasound and sesta-MIBI scintigraphy studies, which were consistent across them. None had a family history that might indicate a multiple endocrine neoplasia (MEN), known thyroid disease, previous neck incision, or suspicion of carcinoma. Surgery was performed through a 1.5 cm central cervical incision and the use of harmonic scalpel. IPTHM was not performed in either case. Results: In all cases the topographic location of the adenoma was confirmed. No signs of hyperparathyroidism persistence or recurrence were registered after a follow-up period of 42 months. There were no recurrent nerve lesions. The average operative time was 24.5 minutes and all patients were discharged within 24 hours. The analgesic requirement was minimal and the cosmetic result satisfactory. Conclusion: The minimally invasive unilateral exploration of the parathyroids with video-assisted magnification without IPTHM, under the guidance of two concordant localization studies is safe and feasible, with comparable results to those of standard technique as well as aesthetic advantages, less postoperative pain and reduced hospitalization.

Objetivo: Mostrar nuestra experiencia realizando la paratiroidectomía miniinvasiva video-asistida con abordaje central para el tratamiento de pacientes con hiperparatiroidismo primario, sin utilizar el monitoreo intraoperatorio de paratohormona (mipth), basados únicamente en la concordancia de dos estudios de localización preoperatorios. Material y métodos: Se seleccionaron 27 pacientes con diagnóstico de hiperparatiroidismo primario, a los cuales se les realizó previo su consentimiento para la realización de un abordaje miniinvasivo, una ecografía cervical y una centellografía sesta-MIBI como estudios de localización pre-operatorios, los cuales fueron concordantes en todo ellos. Ninguno presentó antecedentes familiares que hicieran sospechar una neoplasia endócrina múltiple (NEM), enfermedad tiroidea conocida, cervicotomía previa, ni sospecha de carcinoma. La cirugía se realizó a través de una incisión cervical central de 1,5 cm. con el empleo del bisturí harmónico. El mipth no se realizó en ninguno de los casos. Resultados: En todos los casos se confirmó la ubicación topográfica del adenoma. No registramos persistencias del hiperparatiroidismo ni recidivas después de un período de seguimiento de 42 meses. No hubo lesiones recurrenciales. El tiempo quirúrgico promedio fue de 24,5 minutos y todos los pacientes se fueron de alta antes de las 24 horas. El requerimiento analgésico fue mínimo, y el resultado estético satisfactorio. Conclusión: La exploración unilateral miniinvasiva de las paratiroides con magnificación videoasistida sin mipth, bajo la guía de dos estudios de localización concordantes, es un procedimiento seguro y factible, con resultados comparables a los de la técnica estándar y con ventajas en lo estético, menor dolor postoperatorio y hospitalización reducida.

[Total thyroidectomy treatment of bening multinodular goiter]. / Tiroidectomía total en el bocio multinodular benigno.

INTRODUCTION: The treatment of benign multinodular goiter (BMNB) is a matter of ongoing debate in recent decades despite evidence that total thyroidectomy (TT) is associated with a significant reduction in disease recurrence and minimal morbidity in trained hands. OBJECTIVE: Determine BMNB recurrence after 10 years in 100 patients treated with TT and evaluate the technique-related complications. DESIGN: Prospective non randomized. MATERIAL AND METHODS: From March 1999 to March 2001, one hundred patients, 95 female, with an average age of 42.4 years (range 23-67) underwent TT for having a BMNB, which was confirmed by cervical ultrasound, which also served as a guide to perform fine-needle aspiration (FNA). In all cases, laryngoscopy was performed before and after post-surgical bitstream. RESULTS: Mean operative time was 49 minutes (range 35-58). Recurrencial recorded paralysis (1%) and five hypoparathyroidism (5%), both transient and no definitive case. All patients were discharged within 24 hours of surgery. We did not record any recurrence BMNB a follow-up period of more than 10 years. CONCLUSION: The TT is the treatment choice of BMNB, being an effective, safe, with low rates of complications and to avoid or significantly reduce the recurrence of this disease.

In all cases, laryngoscopy was performed before and after post-surgical bitstream. RESULTS: Mean operative time was 49 minutes (range 35-58). Recurrencial recorded paralysis (1

) and five hypoparathyroidism (5

), both transient and no definitive case. All patients were discharged within 24 hours of surgery. We did not record any recurrence BMNB a follow-up period of more than 10 years. CONCLUSION: The TT is the treatment choice of BMNB, being an effective, safe, with low rates of complications and to avoid or significantly reduce the recurrence of this disease.

Complicaciones del bypass gástrico convencional y laparoscópico. Estudio prospectivo y comparativo / [Complications of conventional and laparoscopic gastric bypass. Prospective and comparative study].

BACKGROUND: Roux-en-y gastric bypass for the management of morbid obesity is currently the safest and more efficient treatment option. the laparoscopic era has shown its benefits in this type of surgery, so some authors advocate its implementation in a practical systematic way. all of which has lead in recent years to the unavoidable change in the surgical approach. OBJECTIVES: To evaluate and compare the complications of laparoscopic gastric bypass and the conventional one in patients with morbid obesity. Application site: self-administration national university hospital. DESIGN: Comparative, prospective no randomized study. POPULATION: Between 2002 and 2011, 420 morbidly obese patients received surgical treatment for the obesity either open (167) or laparoscopic (253) surgery RESULTS: Early postoperative complication rate was 4

in the lbg and 34

in the cbg (p < 05, 95

ci 22-38), mostly represented by seromas (25

) and wall abscesses (5.4

). the percentage of late postoperative complications was 2.8

in the lbg group and 9.6

in the cbg (p=0.004, 95

ci 1.4-12.2), the most frequent being incisional hernias (7.18

). CONCLUSIONS: According to our experience and consulted literature, laparoscopic gastric bypass is a safe, reproducible and with a lower rate of both early and late complications than cbg, and so we consider and offer lbg as the ideal technique for the treatment of patients with morbid obesity.

Tiroidectomía total en el bocio multinodular benigno. / [Total thyroidectomy treatment of bening multinodular goiter].

INTRODUCTION: The treatment of benign multinodular goiter (BMNB) is a matter of ongoing debate in recent decades despite evidence that total thyroidectomy (TT) is associated with a significant reduction in disease recurrence and minimal morbidity in trained hands. OBJECTIVE: Determine BMNB recurrence after 10 years in 100 patients treated with TT and evaluate the technique-related complications. DESIGN: Prospective non randomized. MATERIAL AND METHODS: From March 1999 to March 2001, one hundred patients, 95 female, with an average age of 42.4 years (range 23-67) underwent TT for having a BMNB, which was confirmed by cervical ultrasound, which also served as a guide to perform fine-needle aspiration (FNA).

Ablación con láser de la vesícula biliar en un modelo animal / Gallbladder ablation with a laser in an animal model

Introducción En los años ochenta comenzaron los intentos para eliminar la vesícula biliar de manera no quirúrgica, aplicando químicos, calor o láser para eliminar su mucosa y reducirla a una cicatriz inocua. El objetivo de este trabajo es determinar si con la aplicación de láser de diodo se puede realizar una ablación completa de este órgano. Material y métodos Se dividieron 30 conejos en tres grupos de 10 animales. Se accedió quirúrgicamente a la vesícula biliar, y se aplicó láser diodo de 980nm endoluminalmente a través de una fibra óptica hasta lograr su retracción. En uno de los grupos controles se usó etanol como esclerosante más cola de fibrina para obturar la luz vesicular y en el restante solución fisiológica. A los 65 días se sacrificaron los animales y se observó el resultado del procedimiento macroscópica e histológicamente evaluando la presencia de luz vesicular remanente, la fibrosis, y áreas de reepitelización. Análisis estadístico: test de Fisher. Resultados Ocho de las vesículas tratadas con láser desaparecieron dejando una pequeña cicatriz subhepática. No hubo complicaciones intra- ni postoperatorias. En el grupo del etanol el resultado fue exitoso solo en un caso, con solución fisiológica no hubo ablación. La comparación de los resultados demostró una diferencia significativa favorable al grupo tratado con láser en comparación con el de etanol más cola de fibrina (p<0,0055) y el de solución fisiológica (p<0,0007).Conclusiones En este modelo experimental fue posible la ablación de la vesícula biliar usando láser de diodo (AU)

Introduction Attempts to remove the gallbladder by non-surgical means began in the 1980's, by applying chemicals, heat or laser to remove its mucosa and reduce it to an innocuous scar. The aim of this work is to determine whether complete ablation of this organ is possible using total ablation by applying a diode laser. Material and methods Thirty rabbits were divided into 3 groups of 10 animals. The gallbladder was surgically accessed and a 980nm diode laser was applied endoluminally using fibre optics until it shrunk. Ethanol was used as a sclerosing agent plus a fibrin tail to seal the gallbladder lumen in one of the control groups, and a physiological solution was used in the rest. The animals were slaughtered at 65 days and the results of the procedure were observed macroscopically and histologically, evaluating the remains of the gallbladder lumen, fibrosis, and areas of re-epithelialisation. Statistical analysis was made using the Fisher test. Results Eight of the gallbladders treated by laser disappeared leaving a small sub-hepatic scar. There were no complications during or after surgery. The results were successful in only case in the ethanol group, and there was no ablation with physiological solution. The comparison of the results showed a significant positive difference in the group treated with laser compared to those with ethanol plus fibrin tail (P<.0055) and the physiological solution (P<.0007).Conclusions Ablation of the gallbladder using a diode laser was possible in this experimental model (AU)

[Chemical ablation of the gallbladder with sodium hypochlorite in an animal model]. / Ablación química de la vesícula biliar con hipoclorito de sodio en un modelo animal.

INTRODUCTION: The cholecystectomy is the current treatment of the biliary lithiasis. Nevertheless there have been attempts in order to eliminate the gallbladder epithelium and to generate the sclerosis of the organ using chemical substances, heat and laser. OBJECTIVE: Sodium hypochlorite and fibrin glue is proposed to achieve the ablation of the gallbladder mucosa and sclerosis. MATERIALS AND METHODS: Thirty rabbits were divided into three groups of 10. Accessing surgically to the gallbladder, sodium hypochlorite was injected, afterward the same was done with fibrin glue to occlude the cystic duct and collapse the organ lumen, avoiding the bile reflux. In the control groups ethanol plus fibrin adhesive and physiological solution was used. In day 65 the animals were sacrificed and the result of the procedure was observed macroscopic and histologically. RESULTS: Eight of the gallbladders treated with sodium hypochlorite disappeared leaving a small subhepatic scar. There were no intra nor postoperative complications. In the group of the ethanol the result was successful only in one case, and with saline solution there was no ablation. A significant difference exists for the group treated with sodium hypochlorite plus fibrin glue compared to the ethanol plus fibrin adhesive group (p <0,0055) and the saline solution group (p <0,0007). CONCLUSION: In this experimental model there was possible the ablation of the gallbladder using sodium hypochlorite as sclerosing agent and fibrin glue to collapse the lumen and to occlude the cystic duct.
