[Tratamiento endovascular exitoso de aneurisma del ventrículo izquierdo en un paciente pediátrico].

BACKGROUND: Aneurysms and diverticula of the left ventricle are rare entities in childhood, with a prevalence of less than 0.1%. Described since 1886, as a severe and potentially fatal disease if not corrected, mainly due to the presence of associated anomalies and the risk of rupture. OBJETIVE: Present other management options for ventricular diverticula, different from surgical options, using alternative materials that are not used very often in daily practice. METHOD: A detailed description of a case successfully managed with these new treatment modalities. RESULTS: Endovascular management of the left ventricular diverticulum, diagnosed prenatally in the patient presented, was successful after initial failure with surgical management. CONCLUSIONS: Endovascular management of ventricular diverticula, using alternative materials to those commonly used, is an attractive option with satisfactory results in these patients.

Calyceal diverticulum simulating a renal tumor.

Calyceal diverticulum (CD) is a rare anatomic anomaly with an incidence of 0.2% to 0.6% in the patients undergoing renal imaging. They are considered benign lesions and malignancy is exceedingly rare. For diagnosis it is suggested to perform a multiphasic contrast-enhanced computed tomography (CT) evidencing a diverticulum of the pelvicalyceal system with thin-walled cavities communicating with the central collecting system. However, they can be usually mistaken as kidney cancers leading to unjustified nephrectomy. Here, we present a case of a 34-year-old patient who underwent surgery in 2022 due to suspected kidney cancer and histopathological analysis surprisingly reported a CD.

Emergent hybrid surgical approaches for non-dissecting ruptured Kommerell's aneurysm: a case report series.

BACKGROUND: Kommerell's aneurysm is a saccular or fusiform dilatation found in 3-8% of Kommerell's diverticulum cases. A non-dissecting rupture rate of 6% has been reported. If ruptured, emergent surgical correction is usually granted. However, evidence regarding the optimal surgical approach in this acute setting is scarce. In this case report series, we aim to describe our experience managing type-1 non-dissecting ruptured Kommerell's aneurysm with hybrid emergent surgical approaches. CASES PRESENTATION: From January 2005 to December 2020, three cases of type-1 non-dissecting ruptured Kommerell's aneurysm requiring emergent surgical repair were identified. The mean age was 66.67 ± 7.76 years, and 3/3 were male. The most common symptoms were atypical chest pain, dyspnoea, and headache (2/3). The mean aneurysm's diameter was 63.67 ± 5.69 mm. Frozen Elephant Trunk was the preferred surgical approach (2/3). The Non-Frozen Elephant Trunk patient underwent a hybrid procedure consisting of a supra-aortic debranching and a zone-2 stent-graft deployment. We found a mean clamp time of 140 ± 60.75 min, cardiac arrest time of 51.33 ± 3.06 min, and a hospital stay of 13.67 ± 5.51 days. The most common complications were surgical-site infection and shock (2/3). Only one patient died (1/3). CONCLUSION: Evidence of management for non-dissecting ruptured Kommerell's aneurysms is scarce. Additional, robust, and more extensive studies are required. The selection of the appropriate surgical approach is challenging, and each patient should be individualized. Frozen Elephant Trunk was feasible for patients requiring emergent surgical repair in our centre. However, other hybrid or open procedures can be performed.

Tracheal Diverticulum as a Cause of Recurrent Infection in Post-Lung Transplant Patients: A Report of 2 Cases.

BACKGROUND: Tracheal diverticulum (TD) is a rare entity in clinical practice, accidentally found by imaging methods. It is a potential factor for the development of chronic respiratory infections, contributing to the progression of preexisting lung diseases and putting the success of lung transplantation at risk. OBJECTIVES: This paper reports 2 cases of TD with atypical clinical presentation in post-lung transplant patients with recurrent infections and aims to present the importance of this differential diagnosis. DISCUSSION: Case 1: A 30-year-old man with terminal lung disease underwent bilateral lung transplantation with a satisfactory postoperative period. He presented with TD as a focus of recurrent infection associated with persistent hemoptysis. Indicated for surgical resection (cervicotomy with resection of tracheal diverticulum), without complications. He evolved uneventfully in the postoperative period and was clinically stable at follow-up. Case 2: A 57-year-old woman with hypersensitivity pneumonia associated with secondary pulmonary arterial hypertension and bronchiectasis underwent bilateral lung transplantation without complications. She presented with TD as a focus of infection associated with esophageal symptoms. Indicated for the surgical approach (cervicotomy with resection of tracheal diverticulum), she was asymptomatic at follow-up. CONCLUSION: Conservative treatment is recommended in elderly and asymptomatic patients. Surgical resection is based on the recurrence of symptoms and failure of clinical therapy and is the preferred approach for reported cases.

Risk factors of postoperative sexual function in patients with urethral diverticulum and their partners: A cohort study of 83 women.

INTRODUCTION AND OBJECTIVE: Several studies have focused on the treatment and recurrence of urethral diverticulum (UD). However, few investigations have addressed sexual function in pati-ents with UD. Therefore, we sought to examine sexual function in women affected by UD. MATERIALS AND METHODS: There were 108 accepted cases involving transvaginal diverticulectomy at our institution. Ultimately, 83 women were included for further analysis, only 61 of these wo-men had sexual partners. We collected data for the Female Sexual Function Index (FSFI) from the female patients and the Male Sexual Health Questionnaire (MSHQ) from their male partners before and after surgery. RESULTS: Preoperatively, the UD size affected the female patient's arousal and lubrication (p=0.04), and the UD location affected their satisfaction. However, no significant between-group differences were found in the total FSFI score. For all women, sexual activity improved after surgery (p=0.0087). In addition to improvements in arousal for women with a large UD, improvements in lubrication were affected by the UD size, number and shape, increases in sa-tisfaction scores were impacted by the UD location and shape, and pain relief was linked to the UD number and shape. Analysis of the MSHQ results revealed no between-group differences among the male partners. CONCLUSION: Only the UD size and location affected sexual function in women with a small UD. Surgery could improve female sexual function but did not affect the sexual function of the patient's partners.

[Lemmel's syndrome: report of a case]. / Síndrome de Lemmel: reporte de un caso.

Lemmel's syndrome is a very rare condition as a cause of obstructive jaundice secondary to the presence of a duodenal diverticulum. We report a case, a 68-year-old female patient with a cholestatic pattern, biliary tract dilatation, who underwent ERCP, with a juxtapapillary diverticulum compressing the distal bile duct, which was sphincterotomy.

Divertículo duodenal simulando neoplasia quística de páncreas / Duodenal diverticulum as a cystis neoplasm of pancreas

Resumen Objetivo: El divertículo duodenal se presenta con una frecuencia del 1 al 23% según series radiológicas y de autopsias. La localización más frecuente es la segunda porción duodenal cercana a la cabeza pancreática, por lo cual puede ser confundido con neoplasias pancreáticas quísticas. Material y Método: Presentamos un paciente con diagnóstico de sospecha radiológica, mediante ecoendoscopia y punción aspiración con aguja fina (PAAF), de neoplasia mucinosa de páncreas que fue intervenido, encontrándose un endurecimiento de la cabeza pancreática y un divertículo duodenal yuxtavateriano, realizándose extirpación en bloque ante la sospecha de malignidad. Resultado: El posoperatorio del paciente fue favorable y el resultado anatomopatológico del tejido pancreático informó de tejido pancreático sin anomalías y divertículo duodenal. Discusión: El diagnóstico diferencial preoperatorio del divertículo duodenal con la neoplasia mucinosa quística de páncreas es muy complejo, ya que la punción del líquido del interior del divertículo puede ser similar al de un proceso neoplásico mucinoso pancreático. Ante la sospecha diagnóstica y la presencia de clínica está indicado realizar laparotomía exploradora, para obtener un diagnóstico de certeza.

Objective: The duodenal diverticulum presents with a frequency of 1 to 23% according to radiological series and autopsies. The most frequent localization is the second duodenal portion near the pancreatic head so it may be confused with cystic pancreatic neoplasms. Material and Method: We present a patient with diagnosis of radiological suspicion by means of echoendoscopy and fine needle aspiration biopsy (FNAB) of a mucinous neoplasm of the pancreas that was intervened, being a hardening of the pancreatic head and a duodenal juxtavaterian diverticulum, being performed a block removal on suspicion of malignancy. Result: The patient's postoperative period was favorable and the anatomopathological result of the pancreatic tissue was of pancreatic tissue without anomalies and duodenal diverticulum. Discussion: The preoperative differential diagnosis of duodenal diverticulum with mucinous cystic neoplasia of the pancreas is very complex, since the puncture of the fluid inside the diverticulum may be similar to that of a neoplastic process of the pancreatic mucin. Before the suspected diagnosis and the presence of clinic is indicated to perform exploratory laparotomy, to obtain a diagnosis of certainty.

Congenital diverticulum of the left ventricle is a rare cardiac malformation usually associated with midline thoraco-abdominal defects and other congenital cardiac malformations.

[Digestive bleeding due to jejunal diverticula: A case report and literature review]. / Sangrado digestivo por divertículos yeyunales: reporte de un caso y revisión de la literatura.

BACKGROUND: Bleeding from the small bowel is a rare pathology that represents 5-10% of gastrointestinal bleeding; 0.06% to 5% of cases are due to the presence of diverticula of the small intestine. The majority of diverticula are asymptomatic and present symptoms when there is a complication. CLINICAL CASE: We present the case of a 53-year-old male with a history of chronic renal failure and hypertension. While he was hospitalized due to cerebrovascular disease he recurrently presented lower gastrointestinal bleeding that required blood transfusion on several occasions. Upper gastrointestinal bleeding and colon bleeding were ruled out by endoscopy. It was not until an arteriography was performed that we identified bleeding at proximal jejunum level, and therefore we performed a laparotomy. We present the studies and management that the patient underwent. CONCLUSION: Although jejunal diverticula are rare, they must be included in the differential diagnosis of lower gastrointestinal bleeding when present in a patient. Arteriography is a study of great use in locating the site, provided the bleeding is more than 0.5ml/minute.

[Kommerell's Diverticulum (KD)]. / Divertículo de Kommerell (DK).

Right aortic arch with aberrant left subclavian artery from a Kommerell's diverticulum is a very rare variant of the incomplete vascular ring. Associated symptoms are caused due to tracheal or esophagus compression. Magnetic resonance is the gold standard for diagnosis. Surgical treatment is recommended for symptomatic patients or asymptomatic patients with a large diverticulum. We report three consecutive cases of patients with Kommerell's diverticulum, aberrant left subclavian artery, and right-sided aortic arch.

Jejunal diverticulitis as a cause of acute abdomen / Abdome agudo por diverticulite de jejuno

O objetivo deste relato é ilustrar um caso de diverticulose jejunal que evoluiu para um quadro de abdome agudo.

Factores predictivos de conversión laparoscópica en el tratamiento electivo de la enfermedad diverticular / Predictive factors of laparoscopc conversion in the elective treatment of diverticular disease

Introducción: en las últimas décadas la utilización del abordaje laparoscópico en el tratamiento de enfermedades colorrectales, ha experimentado un auge significativo, logrando disminuir la morbimortalidad del tratamiento. Estos beneficios se pierden ante la necesidad de conversión. Objetivos: nos propusimos identificar los factores preoperatorios predictivos de conversión del procedimiento laparoscópico, en el tratamiento electivo de la enfermedad diverticular validando su aplicación, y evaluar las consecuencias de la conversión. Material y método: se realizó un estudio retrospectivo, descriptivo, observacional de los pacientes con diagnóstico de enfermedad diverticular, operados electivamente por técnica laparoscópica, en el Servicio de Coloproctología del Hospital Británico de Buenos Aires, durante el período comprendido entre junio de 1993 y junio de 2011. Se evaluaron las siguientes variables: edad, sexo, el índice de masa corporal, el riesgo quirúrgico según la American Society of Anesthesiologists (ASA), existencia de cirugías previas, motivo de indicación de cirugía, el tiempo operatorio, la recuperación del tránsito intestinal y la duración de la estadía hospitalaria. Se realizó un análisis univariado de las variables preoperatorias e intraoperatorias. Utilizando la prueba t de Student, se tomó estadísticamente significativo un valor de p < 0,05. Comparamos la morbilidad en relación a dichas variables. Resultados: se realizaron 126 procedimientos, 97 exclusivamente por laparoscopía y 29 requirieron de una laparotomía para su resolución. La edad promedio de la serie fue de 62,3 años de edad (rango 31-88). Setenta y nueve correspondiendo al sexo masculino (62.9%) y 47 al sexo femenino (37.3%). El IMC promedio fue de 25,1 kg/m2. Ochenta y cuatro pacientes fueron clasificados como ASA 1; 35, ASA 2 y 7, ASA 3... (TRUNCADO).

Background: in recent decades the use of laparoscopy in the treatment of colorectal diseases, has experienced an increase significant, achieving treatment reduce morbidity and mortality. These benefits are lost with the conversion. Objectives: we proposed identify preoperative factors predictive of conversion of laparoscopic procedure in the elective treatment of diverticular disease, validating their application, and evaluate consequences of the conversion. Material and methods: retrospective, descriptive, observational study of patients with diagnosis of diverticular disease, were electively operated by laparoscopic technique in the service of Coloproctology British Hospital of Buenos Aires during the period between June 1993 and June 2011. Following variables were evaluated: age, sex, body mass index, surgical risk according to the American Society of Anesthesiologists (ASA), existence of previous surgery, reason for surgery indication, operative time, recovery of intestinal transit and time of hospital stay. A univariate analysis of preoperative and intraoperative variables was performed. Using the Student t test, a P value <0.05 was statistically significant take. We compared morbidity in relation to these variables. Results: one hundred and twenty-six procedures were performed. Ninety-seven exclusively by laparoscopy and 29 laparotomy required for resolution. The average age of the series was 62.3 years (range 31-88). Seventy-nine corresponding males (62.9%) and 47 females (37.3%). The average BMI was 25.1 kg/m2. Eighty-four patients were classified as ASA 1, 35, 2 and 7 ASA, ASA 3. Seventy-four patients had a history of previous abdominal surgery (58.7%). Ninety-four (74.6%) patients corresponded to uncomplicated diverticulitis, and 32 (25.3%) present complicated diverticulitis. Operative time was 175 minutes for the laparoscopic group, while for the conversion group was 262 minutes. The conversion rate of the series was 23% (29/126)... (TRUNCADO).
