Management of a hydatid cyst in a center with high prevalence. Descriptive series.

Hydatidosis is a zoonosis caused by the larval stage of the genus Echinococcus. Humans are an accidental intermediate host. The main organ affected is the liver (70%). The incidence increases in endemic regions such as North Africa, Eastern Europe and South America. We present a descriptive series of cases treated in our hospital in the last 5 years. Demographic variables, cyst characteristics, as well as preoperative and postoperative variables are collected.

Peritoneal tuberculosis mimicking colonic carcinomatosis.

Pulmonary Tuberculosis (TB) has increased in Spain in recent years due to multiple factors. Peritoneal tuberculosis represents the sixth cause of extrapulmonary tuberculosis, accounting for 11% of tuberculosis cases. We report a 28-year-old male from Mali, who arrived at our hospital with an acute abdomen due to intestinal perforation with a computed tomography scan (CT) performed peritoneal tuberculosis mimicking primary carcinomatosis. This presents a diagnostic and therapeutic challenge, since the surgical approach differs in both cases, and the prognosis is very different between them.

Giant cavernous mesenteric lymphangioma in an adult.

We report the exceptional case of a 71-year-old patient with a giant mesenteric mass causing mass effect, dyspnea and abdominal pain. After surgical resection and histopathological analysis of the specimen, the result was a cavernous lymphangioma, an unusual diagnosis due to both the location and age of presentation.

Myolipoma of the round ligament of the liver: a diagnosis to be considered.

A 39-year-old patient consulted for an incidental finding of a mesenteric-epiploic mass measuring 11x6x9.5 cm. Laparoscopic excision of the lesion and cholecystectomy were indicated, revealing a myolipomatous mesenchymal neoplasm in the hepatic round ligament.

Emphysematous hepatitis: a very rare entity with a poor prognosis.

A 67-year-old female, with no alterations in glucose metabolism or other relevant history, presented to the Emergency Department due to abdominal pain and vomiting after a syncopal episode. Physical examination revealed a poor general condition, mild stupor and a distended abdomen, painful on palpation in the right hypochondrium, with localized rigidity. On arrival at the Emergency Department, the patient's blood pressure (BP) was 150/66 mmHg, heart rate (HR) was 110 beats/minute and temperature 35 °C.

[Prevalence and associated factors to non-alcoholic steatohepatitis in obese patients subjected to bariatric surgery]. / Prevalencia y factores asociados a la esteatohepatitis no alcohólica en pacientes obesos sometidos a cirugía bariátrica.

INTRODUCTION: Non-alcoholic fatty liver disease has a high prevalence among obese patients. It has been difficult to identify clear predictors of chronic liver damage, which could help in selecting patients for liver biopsy and therapeutic options. The aim of the study is to describe the liver damage in these obese patients and identify predictors of liver damage progression. PATIENTS AND METHOD: 76 obese patients submitted to bariatric surgery were included. Liver biopsies were taken at the time at the time of the surgery. Clinical and biochemical variables were analyzed. RESULTS: 67 patients (88.1%) were found to have non-alcoholic fatty liver disease; 41 (61.2%) had simple steatosis, and 26 (38.8%) had non-alcoholic steatohepatitis. Patients with non-alcoholic steatohepatitis had significantly higher values of GGT. Non-alcoholic steatohepatitis was associated with diabetes (p < 0.01) in these patients. CONCLUSIONS: Non-alcoholic fatty liver disease is highly prevalent in morbidly obese patients. Non- alcoholic steatohepatitis seems to be associated with diabetes and high values of GGT in obese patients.

[Influence of bariatric surgery on the non-alcoholic liver steatosis. A histological evaluation]. / Influencia de la cirugía bariátrica en esteatosis hepática no alcohólica. Evaluación histológica.

INTRODUCTION: Non-alcoholic fatty liver (NAFL) is highly prevalent in obese patients. The aim of this study is to look at the development of the histological lesions in these patients that we treated using biliopancreatic diversion. MATERIAL AND METHODS: A liver biopsy was performed on 76 obese patients who were operated on using bariatric surgery. Another liver biopsy was performed on 39 of them between 12 and 24 months after the surgery. The clinical and analytical variables at the time of the surgery, and at 18 months were analysed. RESULTS: A total of 67 patients (88.1%) had NAFL at the time of the operation. Simple steatosis was seen in 41 (61.2%) patients and 26 (38.8%) had non-alcoholic steatohepatitis (NASH). An improvement was seen in both the associated pathology and the analytical evaluations. A significant improvement was observed in the degree of steatosis as well as the NASH in the second biopsy performed on 39 patients. There were no deteriorations in the lesions in any of the patients. CONCLUSIONS: There is a high prevalence of NAFL among obese patients. Bariatric surgery (Scopinaro) leads to weight loss which is associated to an improvement in the pathology associated with obesity, as well as a significant decrease in the liver function values. After weight loss, almost all our patients showed an improvement in the histological hepatic lesions, and in particular, that NASH disappeared in 85% of them.
