ABSTRACT

BACKGROUND: The presence of bile stasis is a frequent mechanism for presenting choledocholithiasis and recurrence of this one. The bile duct angulation, also known as "elbow sign," could be a risk factor for reducing the flow of bile and forming stones and it has been reported as a consequence secondary to the use of T-tube. The recurrence of choledocholithiasis without the use of T-tube in the bile duct is minimal, whereas in those with T-tube is four times higher in bile duct exploration surgeries. We present a case report of a patient who underwent T-tube laparoscopic bile duct exploration surgery, who had a bile duct angulation and residual choledocholithiasis as a complication. CASE REPORT: 34-yeard-old female, who presented acute cholecystitis and underwent cholecystectomy. In this operation it was detected choledocholithiasis, which is why it was carried out a T-tube bile duct exploration surgery for acute cholecystitis, without solving the choledocholithiasis condition. Afterwards, she had three endoscopic retrograde cholangiopancreatography procedures, requiring endoscopic hemoclip. Four months later, she was referred to a third-level hospital for definitive treatment with unsolved choledocholithiasis. CONCLUSIONS: The bile duct angulation by T-tube is unusual and it favors bile duct dilatation, stasis of bile pigments and new stones formation. We consider that the best surgical option is the biliary bypass.


INTRODUCCIÓN: La presencia de estasis biliar es un mecanismo frecuente para presentar coledocolitiasis y su recurrencia. La angulación del conducto biliar, también llamada «signo del codo¼, puede ser un factor de riesgo para disminuir el flujo biliar y propiciar la formación de litos, y ha sido reportada como una complicación del uso de sonda en T. La posibilidad de recurrencia de la coledocolitiasis sin colocación de sonda en T en una exploración quirúrgica de vía biliar es mínima, y en aquellas con sonda es cuatro veces mayor. Se presenta el caso de una paciente operada de exploración de la vía biliar con colocación de sonda en T que presentó como complicación una angulación de la vía biliar y coledocolitiasis residual. CASO CLÍNICO: Mujer de 34 años con colecistitis crónica litiásica agudizada que fue sometida a colecistectomía. En la intervención se notó la presencia de coledocolitiasis, por lo que se hizo una exploración de vía biliar y se colocó una sonda en T, sin resolver el cuadro de coledocolitiasis. Posteriormente se hicieron tres colangiopancreatografías retrógradas endoscópicas que fueron fallidas, lo cual ameritó la colocación de hemoclip por sangrado. Cuatro meses después, la paciente fue referida a tercer nivel con diagnóstico de coledocolitiasis no resuelta para tratamiento definitivo. CONCLUSIONES: La angulación de la vía biliar por sonda en T es poco frecuente y favorece la dilatación del conducto biliar común, la estasis de pigmentos biliares y la formación de litos. Consideramos que la mejor opción quirúrgica es la derivación biliodigestiva.

ABSTRACT

BACKGRONUND: Bronchogenic cysts result from abnormal budding of the primitive tracheobronchial tube and are rare congenital cystic lesions. The location of the cyst depends on the embryological stage of abnormal budding. Although periesophageal bronchogenic cysts have been frequently reported, a completely intramural cyst is very rare. CLINICAL CASE: A 42-year-old female patient, a three-month course with retrosternal pain associated with food intake, accompanied by intermittent dysphagia to solids. Esophagogram, high resolution thoracic tomography and endoscopic ultrasound are performed, concluding a probable esophageal bronchogenic cyst. Resection is performed by video-assisted thoracic surgery, without complications. Patient presents with adequate evolution and complete remission of the symptomatology. CONCLUSION: Bronchogenic cysts of the esophageal wall are extremely uncommon lesions. Its surgical treatment is indicated to be symptomatic; video-assisted thoracoscopic surgery resection is of choice, with excellent long-term results and minimal morbidity.


ANTECEDENTES: Los quistes broncogénicos son lesiones congénitas raras que resultan de brotes anormales del tubo traqueobronquial primitivo. La localización del quiste depende de la etapa embriológica del brote anormal. Aunque los quistes broncogénicos periesofágicos han sido frecuentemente reportados, un quiste completamente intramural es muy raro. CASO CLÍNICO: Mujer de 42 años con cuadro de 3 meses de evolución, con dolor retroesternal asociado a la ingestión de alimentos, acompañado de disfagia intermitente a sólidos. Se realiza esofagograma, tomografía de tórax de alta resolución y ultrasonido endoscópico, que concluyen probable quiste broncogénico esofágico. Se realiza resección por cirugía torácica videoasistida, sin complicaciones. La paciente cursa con adecuada evolución y remisión completa de la sintomatología. CONCLUSIÓN: Los quistes broncogénicos de la pared esofágica son lesiones extremadamente poco comunes. Está indicado su tratamiento quirúrgico al ser sintomáticos; es de elección la resección por cirugía torácica videoasistida, con excelentes resultados a largo plazo y mínima morbilidad.

ABSTRACT

BACKGROUND: The relevance of biliary tract injury patients is not only related to diagnosis and treatment but also to follow-up for the possibility of late complications and medical and legal aspects. Hepatobiliary scintigraphy has played a principal roll in diagnosis of many hepatobiliary diseases. METHODS: We carried out a descriptive and retrospective study. Included were all patients with biliary tract injuries who underwent biliary reconstruction and liver biopsy. Clinical, laboratory exams and hepatobiliary scintigraphy follow-up was done. RESULTS: From January 2001 to december 2009 one hundred patients, sixty-five women and thirty-five men were registered. According to Strasberg's classification we had 13 % type E1, 17 % type E2, 38 % type E3 and 32 % type E4. All of them underwent biliary tract reconstruction, eighty-four Hepp-Couinaud type and sixteen conventional jejunum-hepatic anastomosis (Roux-Y). Liver biopsy demonstrated twelve patients with inflammation, forty-nine with cholestasis, nineteen with ductular proliferation and nineteen with fibrosis. When we compare pathologic results of liver biopsy with pre and postoperatively hepatobiliary scintigraphy we found significance in those patients with cholestasis and ductular proliferation in hepatobiliary scintigraphy elimination step, but none in those with inflammation and fibrosis. CONCLUSIONS: Hepatobiliary scintigraphy is an adequate study to the follow-up of patients who underwent hepatobiliary reconstruction been more significative in patients with cholestasis and ductular proliferation.


Introducción: la importancia de casos de lesión de vía biliar no solo involucra el diagnóstico y el tratamiento oportuno, sino también el seguimiento a largo plazo por la posibilidad de complicaciones tardías y los aspectos médico-legales. La medicina nuclear ha desempeñado un papel importante en el diagnóstico de múltiples enfermedades hepatobiliares. Métodos: estudio observacional, retrospectivo, transversal y analítico. Revisión de pacientes con lesión de vía biliar y sometidos a reconstrucción bilio-digestiva y biopsia hepática en la cirugía. Seguimiento clínico, con laboratorio y colangiogamagrama. Resultados: de enero de 2001 a diciembre de 2009 se evaluaron cien pacientes, treinta y cinco hombres y sesenta y cinco mujeres con edad promedio de 38.8 años. Los tipos de lesión de acuerdo con la Clasificación de Strasberg fueron: Tipo E1 (13 %); Tipo E2 (17 %); Tipo E3 (38 %), y Tipo E4 (32 %). Todos los pacientes fueron sometidos a cirugía reconstructiva de la vía biliar, 84 con técnica de Hepp-Couinaud y 16 pacientes con técnica convencional de hepático-yeyuno anastomosis en Y de Roux. Por biopsia hepática, doce pacientes con inflamación, cuarenta nueve colestasis, diecinueve ductopenias y diecinueve fibrosis. Conclusiones: la colangiogamagrafía, es un estudio adecuado en el seguimiento al valorar la captación y eliminación, su mejor utilidad es en pacientes con resultado histopatológico de colestasis y ductopenia.

ABSTRACT

INTRODUCTION: Achalasia is a primary esophageal motor disorder. The most common symptoms are: dysphagia, chest pain, reflux and weight loss. The esophageal manometry is the standard for diagnosis. The aim of this paper is to determine the effectiveness of the surgical management in patients with achalasia in a tertiary care hospital. METHODS: A case series consisting of achalasia patients, treated surgically between January and December of 2011. Clinical charts were reviewed to obtain data and registries of the type of surgical procedure, morbidity and mortality. RESULTS: Fourteen patients were identified, with an average age of 49.1 years. The most common symptoms were: dysphagia, vomiting, weight loss and pyrosis. Eight open approaches were performed and six by laparoscopy, with an average length of cardiomyotomy of 9.4 cm. Eleven patients received an antireflux procedure. The effectiveness of procedures performed was 85.7 %. CONCLUSIONS: Surgical management offered at this tertiary care hospital does not differ from that reported in other case series, giving effectiveness and safety for patients with achalasia.

ABSTRACT

INTRODUCTION: Acute pancreatitis (AP) is usually a mild and self-limiting disease, but some patients develop a severe form that is associated with high mortality. In AP, local inflammation is followed first by the systemic inflammatory response syndrome and then by the compensatory anti-inflammatory response syndrome, which is defined by low human leukocyte antigen (HLA)-DR expression on monocytes, increased concentration of the anti-inflammatory cytokine IL-10, and decreased monocyte function. Our aim was to measure the expression of triggering receptor expressed on myeloid cells (TREM)-1 (a proposed marker of infection or inflammation) and HLA-DR on monocytes, and the serum concentrations of IL-6 (a proinflammatory cytokine) and IL-10 in patients with AP to determine whether these markers can identify patients at high risk of developing severe AP or infection. METHODS: Fifty healthy volunteers, 18 patients with mild AP, and 11 patients with severe AP were included in this study. Samples were taken at admission and one and three days later. TREM-1 and HLA-DR expression was evaluated by flow cytometry, and soluble TREM-1, IL-6 and IL-10 concentrations were measured by ELISA. RESULTS: TREM-1 expression was higher in patients with AP than in healthy volunteers, but there was no difference between patients with mild and severe AP. TREM-1 expression was not associated with mortality or with the presence of infection. Soluble TREM-1 concentration in serum was higher in non-survivors than in survivors. HLA-DR expression was lower and IL-6 concentration higher in patients with severe AP and in infected patients. CONCLUSIONS: Increased TREM-1 expression was associated with the presence of inflammation but not infection in AP. In patients with AP, low HLA-DR expression and high IL-6 concentration could predict severity and infection in samples taken shortly after admission.

ABSTRACT

BACKGROUND: Inflammation is the response of an organism to tissue injury or infection. It is usually limited to the affected tissue, but sometimes the inflammatory mediators reach the bloodstream and act systemically. A compensatory anti-inflammatory response syndrome, in which expression of major histocompatibility complex class II (MHC-II) molecules are decreased, regulates the resulting systemic inflammatory response syndrome (SIRS). SIRS and compensatory anti-inflammatory response syndrome can lead to the development of sepsis. Triggering receptor expressed on myeloid cells (TREM)-1 has been proposed as a biomarker of the presence of sepsis. In this study, we investigated whether TREM-1 is increased only in septic patients, and not in patients with systemic inflammatory response but no infection. We also looked for a possible correlation between TREM-1 and MHC-II expression levels and the patients' progress. MATERIALS AND METHODS: Fifty-eight surgical patients, 14 septic patients and 50 healthy volunteers, were included in this study. TREM-1 and MHC-II expression on blood monocytes was determined by flow cytometry. RESULTS: TREM-1 expression was increased in all patients after surgery, and its expression was higher in patients with preexisting SIRS. No association was found with the presence of infection. In septic patients, the increase in TREM-1 expression was transitory. MHC-II expression was decreased in both surgical and septic patients, and this decrease was greater in patients with a worse outcome. CONCLUSIONS: Increased TREM-1 expression on monocytes is associated with both infectious and noninfectious inflammatory processes, and the levels of MHC-II expression is better correlated with the patient outcome.

ABSTRACT

The open abdomen (OA) strategy is accepted in the treatment of extremely ill surgical patients. Its usage has increased in the last decade as the understanding of its functions, advantages and disadvantages increases. Unfortunately, it continues to be associated with very high morbidity and mortality, and the different techniques used to protect the intra-abdominal contents cannot be standardized for all surgical circumstances. The objective is to review the origins, actual indications and controversies of the staged abdominal repair (STAR) and to report on the latest and most used techniques to ensure an optimal temporary abdominal closure (TAC). A search was done in Medline and Ovid for articles with key words of open abdomen, temporary abdominal closure and staged abdominal repair. We found the use of the technique is justified in patients with trauma, abdominal compartment syndrome and patients with severe intra-abdominal sepsis. The technique used for TAC must always be individualized for each clinical circumstance. The best reported results have been obtained with the vacuum pack technique. In our own experience and as a general rule we discouraged the use of mesh to protect intra-abdominal contents. The strategy of OA is useful in complex surgical situations in extremely ill patients. Its use must be very carefully evaluated, knowing the potentially serious complications that the patient may develop with its use.

ABSTRACT

Surgical site infection is one of the most important health problems representing an increase in morbi-mortality and economical devastation for the patient. There have been a variety of procedures that surgeons have employed to control this situation, from very refined surgical procedures, advanced antimicrobial therapy to local therapy with alginates, hydrocolloid dressings and many others with active topical substances. One of the newest treatments is the VAC (Vacuum-Assisted Closure). This therapy has been proven to be useful in wound infection control and we used it to carry out this study in 38 patients with wound infections. We present the results with this therapy in our institution.

ABSTRACT

INTRODUCTION: Appendix tumors are unusual, accounting for 0.4% of all gastrointestinal- tract malignancies. Although rare, the spectrum of malignant disease is complex and has led to confusion with regard to accurate description of the natural history of these tumors. Consequently, many errors in diagnosis and treatment have occurred. OBJECTIVE: Our aim was to analyze incidence and clinic-pathologic behavior of appendiceal tumors. METHODS: Our study type was retrospective, observational, longitudinal, and descriptive, and was conducted at a secondary-care-level hospital. From a single care center, a histopathologic database of 5,307 appendectomies, all appendiceal tumors, was identified and case notes were reviewed. Analysis of clinical presentation, histopathology, operation, and outcome is presented. RESULTS: During a 10-year period (5,307 appendectomies), 31 patients (0.58%) with appendiceal tumors were identified: 11 had carcinoid tumors, 18 benign, and two patients had malignant tumors. Acute appendicitis was the most common presentation (79.1%), and 20.3% were normal appendices. Patients with appendiceal tumor included 23 females and eight males with mean age of 48 years. Ninety seven percent of patients had preoperative diagnosis of acute appendicitis. CONCLUSIONS: Appendiceal tumors are uncommon and most commonly present as acute appendicitis. Macroscopic suspicion during surgery is the most important point to make the best decision.

ABSTRACT

Antecedentes: las obstrucciones de la vía biliar en general son provocadas por cálculos y neoplasias. Existen otras alteraciones mucho menos frecuentes que pueden provocar obstrucción, entre ellas se encuentran los hamartomas de la vía biliar. Se presenta el caso de una paciente de 34 años diabética, que inicia su padecimiento con dolor abdominal e ictericia. El estudio inicia con ultrasonido de vesícula y vías biliares, que reporta colelitiasis y dilatación de vías biliares. Se realiza CPRE y se descubre una lesión ocupativa del árbol biliar. Se somete a colecistectomía y exploración de la vía biliar. La evolución de la paciente fue satisfactoria. La revisión de patología reporta un hamartoma de la vía biliar extrahepática. Los hamartomas de la vía biliar son neoplasias benignas poco frecuentes, sin embargo, debemos de tenerlas en mente como parte del diagnóstico diferencial.

ABSTRACT

La isquemia mesentérica aguda es un estado de inadecuada perfusión que ocasiona un problema clínico catastrófico con alta morbilidad y mortalidad. El porcentaje de mortalidad se encuentra entre 60 por ciento y 100 por ciento. La lesión intestinal por isquemia depende del estado general de la circulación, del flujo colateral, de la respuesta vascular a estímulos autónomos de las sustancias vasoactivas circulantes y de los productos del metabolismo antes y después de la reperfusión. Cuatro eventos fisiopatológicos se presentan: embolia de la arteria mesentérica superior, trombosis de la arteria mesentérica superior, isquemia no oclusiva, y trombosis de la vena mesentérica superior; la más frecuente es la embolia. La lesión que se observa después de 3 horas de isquemia y 1 hora de reperfusión es mucho más grave que cuatro horas de isquemia. El diagnóstico de isquemia mesentérica requiere de un alto índice de sospecha; el dolor abdominal y la descompensación hemodinámica son los datos clínicos más frecuentes. En la actualidad, la angiografía mesentérica juega un importante papel en el diagnóstico y el inicio del tratamiento con vasodilatadores. Aquellos con persistencia de abdomen agudo requieren de laparotomía exploradora y según sea el caso, exploración vascular. El pronóstico depende de un diagnóstico y tratamiento oportuno.

ABSTRACT

Antecedentes. Los tumores quísticos del mesenterio son lesiones poco comunes, generalmente únicas, que pueden localizarse desde duodeno hasta el recto. La localización más frecuente es en el intestino delgado. Objetivo. Conocer e identificar las manifestaciones clínicas y de gabinete en los pacientes con quiste de mesenterio. Material y método. Se estudió a paciente femenino de 62 años con padecimiento de un año de evolución caracterizado por aumento del perímetro abdominal, dolor abdominal, hiporexia, astenia y adinamia. A la exploración física se corroboró tumoración abdominal. El abordaje diagnóstico incluyó radiografía simple de abdomen y tomografía computada de abdomen. Fue sometida a laparotomía exploradora con diagnóstico preoperatorio de quiste gigante de ovario izquierdo; se resecó un quiste de mesenterio a nivel de sigmoides. La evolución posoperatorio fue satisfactoria. El reporte de histopatología fue de quiste benigno de mesenterio. Conclusión. Los quistes de mesenterio son poco frecuentes. Se deben extirpar cuando presentan sintomatología abdominal importante y por la posibilidad de degeneración maligna
