RESUMO

RESUMEN La hemorragia hepática espontánea (HHE) es una afección rara que resulta de una lesión en el parénquima hepático producida sin una causa externa. Presentamos el caso de una mujer de 74 años que, durante una internación por reagudización de su enfermedad pulmonar obstructiva crónica (EPOC), desarrolla episodio de hemorragia hepática espontánea que evoluciona a shock hemorrágico. Se realiza cirugía con resección atípica de carcinoma hepatocelular (HCC) con hemorragia activa en segmento III hepático. La paciente responde al tratamiento inicial, pero a los 16 días posoperatorios fallece en Unidad de Terapia Intensiva (UTI) debido a una afección respiratoria.


ABSTRACT Spontaneous hepatic hemorrhage (SHH) is a rare condition resulting from a breach in the hepatic parenchyma that occurs without an external cause. We report the case of a 74-year-old woman who, while being hospitalized due to exacerbation of chronic obstructive pulmonary disease (COPD), presented an episode of SHH with hemorrhagic shock. She underwent atypical resection of a hepatocellular carcinoma (HCC) with active bleeding in liver segment III. The patient had a favorable response to the initial treatment but died in the intensive care unit (ICU) on postoperative day 16 due to a respiratory tract complication.

RESUMO

A double-blind randomized controlled trial was performed to compare the safety and efficacy of α-lipoic acid (ALA) in liver transplantation (LT). The grafts were randomized to receive ALA or placebo before the cold ischemia time. Furthermore, patients transplanted with the ALA-perfused graft received 600 mg of intravenous ALA, while patients with the nonperfused graft received the placebo just before graft reperfusion. Hepatic biopsy was performed 2 h postreperfusion. Blood samples were collected before, during and 1 and 2 days after reperfusion. Quantitative polymerase chain reaction (qPCR) analysis was performed on biopsies to assess genes involved in the response to hypoxia, apoptosis, cell growth, survival and proliferation, cytokine production and tissue damage protection. Nine of 40 patients developed postreperfusion syndrome (PRS), but seven of them belonged to the control group. There was a decrease in PHD2 and an increase in alpha subunit of hypoxia-inducible factor-1 (HIF-1α) and baculoviral IAP repeat containing 2 (Birc2) transcript levels in the biopsies from the ALA-treated versus the control group of patients. Additionally, plasma levels of alarmins were lower in ALA-treated patients than control patients, which suggests that ALA-treated grafts are less inflammatory than untreated grafts. These results showed that ALA is safe for use in LT, induces gene changes that protect against hypoxia and oxidative stress and reduces the appearance of PRS.

RESUMO

Antecedentes: los abscesos o colecciones abdominopélvicas sintomáticas se caracterizan por ser una entidad clínico-quirúrgica de origen multifactorial, aunque casi siempre su etología es posoperatoria. Objetivo: describir la aplicabilidad y eficacia del drenaje percutáneo de colecciones abdominales y pelvianas, bajo guía ecográfica, en un servicio de cirugía. Material y métodos: en un período de 9 años se incluyeron todos los pacientes con colecciones ab-dominopelvianas tratados en forma consecutiva con drenaje percutáneo bajo guía ecográfica, en el Hospital Italiano de Bahía Blanca. Resultados: desde junio de 2003 hasta junio de 2012 se trataron 87 pacientes con colecciones abdomi-nopelvianas sintomáticas; en 79 de ellos el tratamiento fue realizado bajo guía ecográfica; 4 pacientes no fueron incluidos en el estudio debido a que el tratamiento se realizó bajo guía tomográfica, y los restantes 4 fueron descartados porque eran pacientes pediátricos. En 51 (64,5%) de ellos, el origen fue posoperatorio. Treinta y ocho (48,1%) pertenecían al sexo femenino. El promedio de edad fue 55 años (rango 18-92). El drenaje se realizó bajo guía ecográfica y radioscópica en 78 pacientes (98,7%) y en uno el abordaje fue ecográfico y laparoscópico. En 15 pacientes (18,9%) se presentaron complicaciones inherentes al procedimiento: 7 pacientes cursaron con febre, 3 refrieron dolor luego de la intervención (abordaje intercostal), en 3 se constataron equivalentes febriles, en una, celulits, y en otra, fistula de colon. De acuerdo con la Clasificación de Dindo-Clavien: 14 puntos Grado I (93,3%) y 1 punto Grado III B (6,7%). No hubo mortalidad asociada al procedimiento; 7 pacientes (8,8%) fallecieron por causas no relacionadas con este. La técnica fue resolutiva en 70 pacientes (88,6%) y satsfactoria en 74 (94%). Conclusiones: el drenaje percutáneo de las colecciones abdominales y pélvicas bajo guía ecográfica en manos del cirujano fue factble y eficaz, lo que la convierte en una técnica segura con baja morbilidad y nula mortalidad.


Background: abscesses or symptomatic abdominal collectons have multifactorial origin, although in more than 65% of the cases, the etology is postoperative. Objective: to describe the applicability and utility of abdominal and pelvic percutaneous drainage guided by ultrasound in a surgical team. Methods: a series of consecutive patents with ultrasound guided percutaneous drainage of abdominal or pelvic collecton performed during in a 9 year period. Results: from June 2003 to June 2012, 87 procedures were performed, 79 of them guided with ultrasound.The etology was postoperative in 51 patents (64.5%). Thirty eight (48.1 %) were female. Average age was 55 (range 18-92). Drainage was performed under ultrasound and radiology guide in 78 patents (98.7%) and by laparoscopic and ultrasound guide in one patent. Fifeen patents (18.9%) presented morbidity related to the procedure: fever in 7 patents, unusual pain in 3 (all with intercostal drainage), chills and sweating in 3, cellulits in one, and a colonic leak in one. All patents were included into of Dindo-Clavien Classificaton of Surgical Complicatons and the results were: Grade I: 14 patents, Grade IIIb: one patent. There was no mortality related to the procedure; seven patents (8.8%) died because of other causes. The overall success rate was 88.6 % (70 cases), and satsfactory in 94% (74 cases). Conclusions: in surgeons hands, ultrasound guided percutaneous drainage of abdominal and pelvic collectons was a feasible, efective and safe procedure with low morbidity.
