[Persistent hiccups after perforated cholecystitis]. / Vedvarende hikke etter perforert kolecystitt.

BACKGROUND: Persistent hiccups lasting more than 48 hours are rare and have numerous possible causes that require further investigation. CASE PRESENTATION: We present a man in his seventies who was admitted to hospital after 11 days of hiccups. The hiccups were preceded by abdominal pain that spontaneously receded after a few hours. At admission he had no abdominal pain during examination, but a CT scan later suggested that the cause was a perforated cholecystitis with an intra-abdominal abscess. The abscess was drained percutaneously and treated with antibiotics, and the hiccups stopped. INTERPRETATION: Persistent hiccups warrant thorough examination, and it is recommended to consider CT scans of the head and truncus, cerebral MRI scan and an upper GI endoscopy. Treating the underlying cause of hiccups is the ultimate target, while symptomatic treatment simultaneously is preferred.

Double cholecystectomy of duplex gallbladder associated with chronic cholecystitis in a cat.

A 6-year-old female neutered Persian cat presented with hyporexia and gradual weight loss over 6 months. Physical examination revealed cranial abdominal pain. Haematology and serum biochemistry were within normal limits. Abdominal ultrasonography and a computed tomography scan suggested a non-neoplastic mass compressing the gallbladder. During an exploratory laparotomy, a duplex gallbladder with two separate cystic ducts was diagnosed intraoperatively. The mass identified using the imaging techniques was an abnormal right gallbladder which was distended with immobile mucoid bile and a thickened wall. The left gallbladder and cystic duct were grossly normal. A cholecystectomy of both gallbladders was performed. Histopathology of the right gallbladder identified chronic cholecystitis. The cat made a good recovery from surgery and reported complete resolution of its hyporexia and a return to normal body weight. This is the first report of a successful cholecystectomy of a duplex gallbladder with chronic cholecystitis of a single gallbladder.

Focused abdominal ultrasound.

A focused point-of-care abdominal ultrasound is an examination performed at the patient's location and interpreted within the clinical context. This review gives an overview of this examination modality. The objective is to rapidly address predefined dichotomised questions about the presence of an abdominal aortic aneurysm, gallstones, cholecystitis, hydronephrosis, urinary retention, free intraperitoneal fluid, and small bowel obstruction. FAUS is a valuable tool for emergency physicians to promptly confirm various conditions upon the patients' arrival, thus reducing the time to diagnosis and in some cases eliminating the need for other imaging.

Deep-learning models for differentiation of xanthogranulomatous cholecystitis and gallbladder cancer on ultrasound.

BACKGROUND: The radiological differentiation of xanthogranulomatous cholecystitis (XGC) and gallbladder cancer (GBC) is challenging yet critical. We aimed at utilizing the deep learning (DL)-based approach for differentiating XGC and GBC on ultrasound (US). METHODS: This single-center study comprised consecutive patients with XGC and GBC from a prospectively acquired database who underwent pre-operative US evaluation of the gallbladder lesions. The performance of state-of-the-art (SOTA) DL models (GBCNet-convolutional neural network [CNN] and RadFormer, transformer) for XGC vs. GBC classification in US images was tested and compared with popular DL models and a radiologist. RESULTS: Twenty-five patients with XGC (mean age, 57 ± 12.3, 17 females) and 55 patients with GBC (mean age, 54.6 ± 11.9, 38 females) were included. The performance of GBCNet and RadFormer was comparable (sensitivity 89.1% vs. 87.3%, p = 0.738; specificity 72% vs. 84%, p = 0.563; and AUC 0.744 vs. 0.751, p = 0.514). The AUCs of DenseNet-121, vision transformer (ViT) and data-efficient image transformer (DeiT) were significantly smaller than of GBCNet (p = 0.015, 0.046, 0.013, respectively) and RadFormer (p = 0.012, 0.027, 0.007, respectively). The radiologist labeled US images of 24 (30%) patients non-diagnostic. In the remaining patients, the sensitivity, specificity and AUC for GBC detection were 92.7%, 35.7% and 0.642, respectively. The specificity of the radiologist was significantly lower than of GBCNet and RadFormer (p = 0.001). CONCLUSION: SOTA DL models have a better performance than radiologists in differentiating XGC and GBC on the US.

Fístula colecistoduodenal sin migración de cálculo: reporte de caso / Cholecystoduodenal fistula without gallstones migration: case report / Fístula colecistoduodenal sem migração de cálculos: relatório de caso

El síndrome de Bouveret es una causa infrecuente de íleo biliar, posee una elevada morbimortalidad. Se produce por la migración de un cálculo, generalmente de gran tamaño, hacia el tracto gastrointestinal a través de una fistula colecistoduodenal. El objetivo de esta carta científica es presentar un paciente con un estadio previo de la enfermedad donde la fistula se encuentra constituida, pero sin migración del cálculo, por lo que el diagnóstico oportuno tendría un impacto favorable en el tratamiento y pronóstico debido a que no se encuentra instaurado el cuadro obstructivo intestinal.

Bouveret's syndrome is a rare cause of biliary ileus, with a high morbimortality. It is caused by the migration of a stone, usually large, into the gastrointestinal tract through a cholecystoduodenal fistula. The objective of this scientific letter is to present a patient with a previous stage of the disease where the fistula is constituted, but without migration of the calculus, so that the timely diagnosis would have a favorable impact on the treatment and prognosis because the obstructive intestinal condition is not established.

A síndrome de Bouveret é uma causa rara de íleo biliar com uma morbilidade e mortalidade elevadas. É causada pela migração de uma pedra, geralmente grande, para o tracto gastrointestinal através de uma fístula colecystoduodenal. O objectivo desta carta científica é apresentar um doente com uma fase anterior da doença em que a fístula está presente, mas sem migração da pedra, para que o diagnóstico atempado tenha um impacto favorável no tratamento e prognóstico, uma vez que a condição obstrutiva instestinal não está estabelecida.

Colecistitis hemorrágica: reporte de caso y revisión de la literatura / Hemorrhagic cholecystitis: case report and literature review

Resumen Introducción: La colecistitis hemorrágica es una complicación poco frecuente de la colecistitis aguda con una alta mortalidad. Materiales y Método: Paciente con dolor abdominal en hipocondrio derecho e ictericia. Los exámenes de laboratorio y ultrasonido hepatobiliar mostraron datos sugestivos de colecistitis aguda; durante su estancia hospitalaria presenta deterioro de su estado general, realizándose tomografía computarizada mostrando imágenes sugestivas de colecistitis hemorrágica y hemoperitoneo. Resultados: Laparotomía de urgencia, corroborando los hallazgos tomográficos y resolviéndose satisfactoriamente con la colecistectomía. Discusión: El diagnóstico de colecistitis hemorrágica es difícil ya que sus manifestaciones clínicas de inicio no difieren de la colecistitis aguda, por lo que la sospecha clínica y el adecuado estudio de imagen son importantes para su detección. Conclusión: A pesar que la colecistitis hemorrágica con perforación y hemoperitoneo es una patología muy poco común, de diagnóstico confuso, es importante establecer la realización de una tomografía computarizada abdominal con contraste endovenoso en pacientes con sospecha de colecistitis aguda grave.

Introduction: Hemorrhagic cholecystitis is a rare complication of acute cholecystitis with a high mortality. Materials and Method: Patient with abdominal pain in right hypochondrium and jaundice. Laboratory analyses and hepatobiliary ultrasound suggested acute cholecystitis, however, general worsening during hospital stay was observed and a computed tomography was performed, revealing hemorrhagic cholecystitis and hemoperitoneum. Results: Urgent laparotomy which confirmed tomographic results, successfully solved with cholecystectomy. Discussion: Hemorrhagic cholecystitis diagnosis is difficult as symptoms at the beginning do not differ from acute cholecystitis, then, clinical suspicion and a correct image analysis is crucial for its detection. Conclusion: Although, perforated hemorrhagic cholecystitis with hemoperitoneum is a very rare entity with confused diagnosis, an abdominal computed tomography with intravenous contrast is very important in any patient with severe acute cholecystitis suspicion.

Colecistectomía con anestesia local como recurso en el paciente anciano / Cholecystectomy with local anesthesia as a resource in the elderly

Ante un paciente con colecistitis aguda lo ideal es extirpar la vesícula biliar. A veces se presentan situaciones especiales en ancianos desnutridos, con deterioro de su estado general, en los que una intervención con anestesia prolongada, incluso con medios pocos invasivos como la videocirugía, pone en peligro la vida del enfermo. En tales casos la colecistectomía con anestesia local es una alternativa que se puede considerar(AU)

In the case of a patient presenting with acute cholescystectomy ideally is to remove the gallbladder. Sometimes there are special situations in malnourished elderlies with deterioration of its general status in whom a lengthy anesthesia intervention, even using not much invasive means as the videosurgery, put at risk the life of patient. In such cases the cholescystectomy with local anesthesia is an alternative that must to be taken into account(AU)
