Hungry bone syndrome following thyroid surgery.

The diagnosis of hypocalcemia-induced tetany following a total thyroidectomy is not common. However, there is a higher risk in patients with a history of gastric bypass surgery due to their malabsorption condition. This case describes postoperative hungry bone syndrome resulting from chronic malabsorption in a patient with a history of bariatric surgery. It is important to consider alternative treatment options if the initial management proves ineffective. Typically, this is a temporary condition, but it's crucial to prioritize prevention in high-risk patients by providing perioperative calcium and vitamin D supplementation.

Mucinous adenocarcinoma arising from complex perianal fistula: a diagnostic and therapeutic challenge.

We present a case of a 64-year-old male with a history of perianal abscesses that have been surgically treated on 10 occasions. Eight months after the last drainage procedure, he presented with a new abscess. Drainage was performed, revealing a cavity with smooth walls, a chronic appearance, filled with mucoid material. An internal fistulous opening was identified at the 6 o'clock position above the anorectal line, which communicated with the described cavity, forming a trans-sphincteric fistula to the mid-anal canal. Biopsy with pathological anatomy showed a mucinous adenocarcinoma with possible intestinal origin (CK20+, CDX2+, TTF1-, CK7+). After completing the evaluation, he was diagnosed with T4N1M0 rectal neoplasia. A diverting colostomy was performed, followed by neoadjuvant therapy, and subsequently, a laparoscopic abdominoperineal amputation. Pathological anatomy revealed residual adenocarcinoma ypT2N0 N0V0L0, R0. This case is notable for both the rarity of a mucinous adenocarcinoma originating in a perianal fistula and the nonspecific clinical presentation of such tumors. Clinical suspicion is crucial, especially in cases of recurrent abscesses with the discharge of mucoid material through fistulous openings, prompting the need for biopsies to ensure proper diagnosis and subsequent optimal treatment.

Ictericia obstructiva secundaria a un pseudoaneurisma de arteria mesentérica superior / Obstructive jaundice secondary to a pseudoaneurysm of the superior mesenteric artery

Los pseudoaneursimas de arteria mesentérica superior son una entidad rara, generalmente asintomáticos pero que pueden debutar con dolor abdominal, masa pulsátil o shock, siendo excepcional la ictericia como forma de presentación. El diagnóstico se realiza mediante pruebas de imagen (TC) y en la actualidad el abordaje endovascular es el más extendido reservándose la cirugía abierta en casos seleccionados. Describimos el caso de una paciente con un pseudoaneurisma de la AMS de 86mm con compresión de la vía biliar extrahepática. (AU)

Obstructive jaundice secondary to a pseudoaneurysm of the superior mesenteric artery.

Superior mesenteric arteries pseudoaneurysms are rare entity, usually asymptomatic but they can appear as an abdominal pain, throbbing mass or shock, being jaundice an exceptional type of presentation. Diagnosis is made by imaging tests (CT) and currently the endovascular approach is the most widespread, reserving open surgery in selected cases. We describe the case of a patient with an 86mm SMA pseudoaneurysm with compression of the extrahepatic bile duct.

Características e impacto del sexo en una cohorte de pacientes con colangitis esclerosante primaria: experiencia de un centro trasplantador de la cuenca mediterránea / Characteristics and impact of sex in a cohort of patients with primary sclerosing cholangitis: Experience of a transplant center in the Mediterranean basin

Introducción y objetivos: La colangitis esclerosante primaria (CEP) es una enfermedad hepática colestásica rara, que típicamente afecta a varones de mediana edad con colitis ulcerosa (CU). No obstante, estudios recientes apuntan a cambios epidemiológicos. Nuestro objetivo es determinar si la epidemiología, presentación clínica y curso evolutivo de pacientes con CEP seguidos en un centro de referencia se asemejan a lo descrito en la literatura. Pacientes y métodos: Búsqueda retrospectiva de pacientes con diagnóstico de CEP atendidos en nuestro centro entre los años 2000 y 2019.Resultados: Cohorte de 55 pacientes (media de edad: 37 años), el 44% mujeres, afectos de CEP, el 79% de ducto grande. Casi dos tercios fueron diagnosticados a partir de 2011. En el momento del diagnóstico, un 63% de los pacientes se encontraba asintomático. La mediana de tiempo desde la sospecha hasta el diagnóstico fue de 2 años. Un 34% desarrolló cirrosis en el seguimiento, y un 25% requirió trasplante hepático (TH) tras una media de tiempo de 7 años; entre estos, la enfermedad recurrió en un 46%. Un 45% presentaba una enfermedad inflamatoria intestinal (EII), sobre todo CU. Si bien no se alcanzó significación estadística, la CEP en mujeres se caracterizó por mayor tasa de presentación asintomática, mayor asociación con CU frente a otras formas de EII, así como cirrosis al diagnóstico y necesidad de TH con mayor frecuencia que los varones.Conclusiones: La epidemiología de la CEP está cambiando. El número de mujeres afectas es mayor al descrito previamente, objetivándose un aumento reciente de la incidencia. Podrían existir diferencias entre sexos en la forma de presentación y evolución que deberán confirmarse en estudios posteriores. (AU)

Background and aims: Primary sclerosing cholangitis (PSC) is a rare cholestatic liver disease that typically affects middle-aged men with ulcerative colitis (UC). However, recent studies point out to epidemiological changes. Our aim was to determine if the epidemiology, clinical course and outcome of patients with PSC followed at a reference hepatology center resemble what is described in the literature. Patients and method: Retrospective search of patients with a diagnosis of PSC treated in our center between 2000 and 2019.Results: Cohort of 55 patients (mean age: 37 years), 44% women. Most were large duct type (79%). Most diagnoses were made after 2011. At time of diagnosis, 63% of patients were asymptomatic. The median time from suspicion to diagnosis was 2 years. After a mean follow-up time of 7 years, one third developed cirrhosis, and 25% required liver transplantation (LT); among these, the disease recurred in almost half. Inflammatory bowel disease (IBD) was present in 45%, especially UC. Although statistical significance was not reached, PSC in women was characterized by higher rate of asymptomatic presentation and more frequent association with UC versus other forms of IBD. Women also had more frequently cirrhosis at diagnosis and required LT more often than men.Conclusion: The epidemiology of PSC is changing. The number of women affected is greater than what was expected from the literature, with a recent increase in incidence. There seems to be differences between sexes in the form of presentation and disease course that should be confirmed in subsequent studies. (AU)
