Intercostal Lung Hernias Presenting After Minimally Invasive Cardiac Surgery.

INTRODUCTION: With the introduction of minimally invasive cardiac surgery, more commonly cases of lung herniation are starting to appear. Acquired lung hernias are classified as postoperative, traumatic, pathologic, and spontaneous. Up to 83% of lung hernias are intercostal. Herein, we describe patients presenting with intercostal lung hernias following minimally invasive cardiac surgery at a single center in Medellín, Colombia. METHODS: We conducted a retrospective search of all patients presenting with intercostal lung hernias secondary to minimally invasive cardiac surgery at our clinic in Medellín since the beginning of our program, from 2010 to 2022. Mini-sternotomies were excluded from our study. We reviewed the incision type and other possible factors leading to intercostal lung hernia development. We also describe the approach taken for these patients. RESULTS: From 2010 up until 2022, 803 adult patients underwent minimally invasive cardiac surgeries through a mini-thoracotomy. At the time of data retrieval, nine patients presented with intercostal lung hernias at the previous incision site. Five hernias (55%) were from right 2nd intercostal parasternal mini-thoracotomies for aortic valve surgeries. Four hernias (45%) were from right 4th intercostal lateral mini-thoracotomies for mitral valve surgeries. Our preferred repair technique is a video-assisted thoracoscopic mesh approach. CONCLUSION: Minimally invasive cardiac surgical approaches are becoming more routine. Proper wound closure is critical in preventing lung hernias. Additionally, timely diagnosis and opportune hernia surgery using video-assisted thoracoscopic mesh repair can prevent further complications.

Management of High Output Enterocutaneous Fistula due to Richter's Hernia After Gastric Bypass: Video Demonstration.

INTRODUCTION: The increase in laparoscopic surgery in patients with obesity increases the incidence of trocar site hernia (TSH). Therefore, TSH represents a risk for the development of Richter's hernia (RH). METHODS: We present the unusual case of a postoperative gastric bypass patient complicated with a high output enterocutaneous fistula through a trocar site wound. RESULTS: The Laparoscopic surgery consists of an RH reduction, enterotomy, and repair of the preperitoneal space. CONCLUSION: RH complicated by high-output enterocutaneous fistula has not been previously reported. It is essential to close the preperitoneal space in bariatric surgery to avoid these complications.

When to use a prophylactic mesh after stoma closure: a case-control study.

PURPOSE: The closure of a stoma is frequently associated with an acceptable morbidity and mortality. One of the most frequent complications is incisional hernia at the stoma site, which occurs in 20%-40% of cases, higher than incisions in other parts of the abdomen. The objective of this study was to identify the risk factors associated with the presentation of incisional hernia after stoma closure, this in order to select patients who are candidates for prophylactic mesh placement during closure. METHODS: An unpaired case-control study was conducted. This study involved 164 patients who underwent a stoma closure between January 2014 and December 2019. Associated factors for the development of incisional hernia at the site of the stoma after closure were identified, for which it was performed a logistic regression analysis. RESULTS: 41 cases and 123 controls were analyzed, with a mean follow-up of 35.21 ± 18.42 months, the mean age for performing the stoma closure was 65.28 ± 14.07 years, the most frequent cause for performing the stoma was malignant disease (65.85%). Risk factor for the development of incisional hernia at the stoma site after its closure was identified as a history of parastomal hernia (OR 5.90, CI95% 1.97-17.68). CONCLUSIONS: The use of prophylactic mesh at stoma closure should be considered in patients with a history of parastomal hernia since these patients present a significantly higher risk of developing a hernia.

A descriptive, prospective and cross-sectional study of the 747 operated patients due to external abdominal hernias in La Atlántida Comprehensive Diagnosis Center from Vargas State, of the Bolivarian Republic of Venezuela was carried out from April, 2013 to December, 2017 with the objective of characterizing them according to variables of interest for the investigation. In the series the male sex (75.1 percent), the age group 51-60 years (37.8 percent, the hypertension as the main comorbidity (32.0 percent), the inguinal hernia as the most frequent variety (63.7 percent), besides the repair with prosthesis without tension (mesh) as the most used procedure and without hernia relapse (72.6 percent) prevailed; also, the complications were within the accepted international range (5.1 percent) and the edema of the cord turned out to be the most common.

Chronic hepatothorax due to right diaphragmatic rupture: an anesthetic challenge in a rare case / Hepatotórax crônico devido à ruptura do diafragma direito: um desafio anestésico em um caso raro

Abstract Background: Diaphragmatic rupture is an uncommon condition, with 90% of ruptures occurring on the left side. However, its incidence on the right side is increasing along with the increase in traffic accidents. Liver herniation may become progressive causing severe atelectasis of the right lung, resulting in impaired respiratory status and hemodynamic changes. Case report: We report the case of a 40 years old female, ASA III, scheduled for hepatothorax repair that evolved from right diaphragmatic hernia after a car accident when she was 8 years old. Clinically, she had severe restrictive respiratory syndrome caused by the hepatothorax. The anesthetic evaluation was normal, except for the chest X-ray showing elevation of the dome of the right hemidiaphragm without tracheal deviation. Diagnosis was confirmed by CT scan. After liver replacement in the abdominal cavity, a transient increase in central venous pressure, stroke volume index and flow time corrected (35%), and a decrease in systemic vascular resistance were observed. After complete hemodynamic and hepatosplenic stabilization, as well as ventilation, the patient was transferred intubated, under controlled ventilation and monitored, to the liver transplant unit. Conclusions: Hepatothorax is a rare condition and its repair may represent an anesthetic challenge. After liver replacement in the abdominal cavity during corrective surgery under general anesthesia complications may occur, particularly associated with pulmonary re-expansion. Effective teamwork and careful planning of surgery, between the surgical and anesthetic teams, are the key to success.

Resumo Justificativa: A ruptura diafragmática é uma condição incomum e ocorre em 90% no lado esquerdo. No entanto, a incidência de ruptura à direita tem vindo a aumentar junto com o aumento dos acidentes automobilísticos. A herniação do fígado pode tornar-se progressiva, causar atelectasia grave do pulmão direito, resultar num débil estado respiratório e alterações hemodinâmicas. Relato de caso: Mulher de 40 anos, estado físico ASA 3, marcada para reparação de hepatotórax que evoluiu de hérnia diafragmática direita, adquirida aos 8 anos, após um acidente automobilístico. Clinicamente apresentava síndrome respiratória restritiva grave, causada pelo hepatotórax. A avaliação anestésica era normal, com exceção da radiografia do tórax, que evidenciava elevação da hemicúpula diafragmática direita, sem desvio traqueal. Diagnóstico foi confirmado por tomografia computadorizada. Depois da recolocação do fígado na cavidade abdominal foram observados um aumento transitório da pressão venosa central, do Stroke Volume Index e Flow Time Corrected (35%) e uma diminuição da resistência vascular sistêmica. Uma vez alcançada a estabilização hemodinâmica geral e hepatoesplênica, bem como da ventilação, a paciente foi transferida entubada, sob ventilação controlada e monitorada para a Unidade de Transplantação Hepática. Conclusões: O hepatotórax é uma condição rara e a sua correção pode representar um desafio anestésico. Após a recolocação abdominal do fígado, durante uma cirurgia corretiva, sob anestesia geral, podem ocorrer complicações, principalmente as associadas à reexpansão pulmonar. Um trabalho em equipe eficaz e o planejamento cuidadoso da cirurgia, entre as equipes cirúrgica e anestésica, são a chave para o sucesso.

MRI findings of postherpetic abdominal wall pseudohernia: A case report.

Herpes zoster is caused by the reactivation of latent varicella-zoster virus from dorsal root ganglia. Although infrequent, simultaneous damage to the anterior horn cells or anterior nerve roots at the same level may result in motor neuropathy. When motor involvement is localized in the abdominal wall, a pseudohernia may be the clinical presentation. We report a case of abdominal wall post-herpetic pseudohernia, with clinical, ultrasound and MRI correlation. MRI demonstrated increased T2/STIR signal intensity in the abdominal wall muscles, suggesting acute denervation. To our knowledge, this is the first case report of postherpetic pseudohernia with acute denervation demonstrated on MRI.

3-D Virtual Reconstruction of a Large Amniocele With Protrusion of Legs and Umbilical Cord Following Asymptomatic Uterine Rupture.

BACKGROUND: Complete uterine rupture is a rare and severe intrapartum complication with high rates of maternal and fetal mortality. Asymptomatic uterine rupture is a very rare condition with one unique previous case described in the literature. Three-dimensional virtual models allow an immersive virtual reality of maternal-fetal structures with better understanding by the parents and the medical team. CASE: We demonstrate a case of asymptomatic rupture uterine with a large amniocele and protruded legs and umbilical cord at 28 weeks of gestation by using a 3-D virtual model from ultrasound scan data. CONCLUSION: 3-D virtual models may be applied to the assessment of obstetric complications, thereby allowing a novel 3-D spatial view of maternal-fetal structures.

Intractable intraoperative brain herniation secondary to tension pneumocephalus: a rare life-threatening complication during drainage of subdural empyema / Herniação cerebral intratável secundária a pneumoencéfalo hipertensivo no intraoperatório: uma complicação rara com risco para a vida durante a drenagem de empiema subdural

Abstract Tension pneumocephalus is rare but has been well documented following trauma and neurosurgical procedures. It is a surgical emergency as it can lead to neurological deterioration, brainstem herniation and death. Unlike previous cases where tension pneumocephalus developed postoperatively, we describe a case of intraoperative tension pneumocephalus leading to sudden, massive open brain herniation out of the craniotomy site. The possible causative factors are outlined. It is imperative to rapidly identify possible causes of acute intraoperative brain herniation, including tension pneumocephalus, and institute appropriate measures to minimize neurological damage.

Resumo O pneumoencéfalo hipertensivo é raro, mas foi bem documentado após trauma e procedimentos neurocirúrgicos. Trata-se de uma emergência cirúrgica porque pode levar à deterioração neurológica, herniação do tronco cerebral e morte. Ao contrário de casos anteriores, nos quais o pneumoencéfalo hipertensivo se desenvolveu no pós-operatório, descrevemos um caso de pneumoencéfalo hipertensivo desenvolvido no período intraoperatório que levou a uma herniação cerebral súbita, maciça e aberta para fora do local da craniotomia. Os possíveis fatores causais são destacados. É imperativo identificar rapidamente as possíveis causas da herniação cerebral aguda no intraoperatório, incluindo o pneumoencéfalo hipertensivo, e instituir medidas apropriadas para minimizar os danos neurológicos.

Expertise, accidents and hernias in the context of the right to health, Colombia 1915-1946.

For most physicians, the assessment of disability in cases of work accident or occupational disease is very relative matter, and clinical judgments are subjective and unsatisfactory in legal settings. Work accident legislation gives them the task of deciding on any causal links between accident and disease and indicating any economic compensation that should be awarded. They must therefore reach beyond their scientific knowledge to understand the multitude of social factors that underlie these problems in the world of work. In this article, we analyze Colombian sources from the first half of the 20th century on the physiology of labor, fatigue, professional risk, work accidents, occupational diseases, among other issues. The aim is to advance understanding of how the field of medical knowledge established an ethical approach for experts in cases of occupational accidents, focusing on hernias, typical misfortunes of the world of work.

Hernia del espacio de Petersen: complicación tardía del bypass gástrico laparoscópico / Petersen’s space hernia: late complication of laparoscopic gastric bypass

Introduction: Petersen's Space Hernia is a protrusion of intestinal loops through a defect between the alimentary loop and the transverse mesocolon that occur as a late complication of Gastric Bypass. Objective: To present our experience in the management of this entity, making emphasis on the difficulty of clinical diagnosis, the typical CT Scan findings and to suggest prevention and management strategies. Method: Case series study of patients with Petersen's Space Hernia after Laparoscopic Gastric Bypass. Clinical presentation, CT Scan findings and surgical results were analyzed. Results: 8 patients. Mean age 43 years. All presented al least 12 months after primary surgery, with unspecific abdominal pain. CT Scan most frequent findings were: Swirled mesentery, engorgement of mesentery vessels and the mushroom sign. Surgery was performed laparoscopically in the 8 patients. No bowel ischemia was found. In all cases, once reduced the protruded loops, complete closure of the defect with a running non absorbable suture was done. Conclusion: In patients with Gastric Bypass, presenting with abdominal pain, a high degree of suspicion must be kept about this entity. Clinical findings are unspecific and radiological study is crucial. When diagnosed on time bowel necrosis is avoided and the main surgical goal is to achieve a complete closure of the defect with non absorbable suture.

Introducción: La Hernia del Espacio de Petersen es una complicación tardía del bypass gástrico, que ocurre por la protrusión de asas intestinales a través del defecto que se genera entre el asa alimentaria y el mesocolon transverso. Objetivo: Presentar nuestra experiencia en el manejo de esta patología, haciendo énfasis en la dificultad del diagnóstico clínico, los hallazgos más típicos de la Tomografía Computada (TC) y sugerir estrategias de prevención y manejo. Método: Estudio de una serie de casos con diagnóstico de Hernia del Espacio de Petersen posterior a bypass gástrico. Se analizó la presentación clínica, los hallazgos imagenológicos e intraoperatorios y los resultados del tratamiento quirúrgico. Resultados: 8 pacientes. Todos se presentaron luego de 12 meses de la cirugía primaria y la manifestación fue dolor abdominal de carácter inespecífico. Los hallazgos más frecuentes de la TC fueron el "arremolinamiento" mesentérico, ingurgitación de los vasos mesentéricos y el "signo del hongo". La cirugía se realizó por vía laparoscópica en los 8 pacientes. No se evidenció isquemia intestinal. En todos los casos, una vez reducido el contenido herniado, se cerró el espacio con sutura continua de material no reabsorbible. No hubo complicaciones ni mortalidad. Conclusión: En los pacientes sometidos a bypass gástrico hay que mantener un alto grado de sospecha acerca de esta entidad. La clínica es inespecífica y el estudio imagenológico es fundamental. Pesquisado a tiempo se puede evitar la necrosis intestinal y el pilar fundamental del tratamiento es lograr un adecuado cierre del defecto con material no reabsorbible.

Herniación de quiste de seno maxilar a través de fístula oroantral: reporte de un caso / Hermiation of a maxillary sinus cyst through an oroantral fistula: report of a case

Los quistes de retención mucosa y los mucoceles son las lesiones máscomunes de los senos paranasales. Éstos comparten características muysimilares y su diferencia estará determinada por su etiología. A diferencia del quiste de retención mucosa, cuyo comportamiento es mucho más sutil, el mucocele causa fenómenos infl amatorios locales, y algunas veces,reabsorción ósea de las estructuras adyacentes. El tratamiento será laenucleación quirúrgica. En el caso clínico que presentamos a continuación,se evidencia una lesión quística que se expone a través del alvéolo no cicatrizal de extracción traumática realizada semanas atrás, además se presenta la técnica que utilizamos para el cierre de fístula oroantral.

Mucus retention cysts and mucoceles are the most common lesions of the paranasal sinuses. They share very similar characteristics and the difference between them depends on their etiology. Unlike mucous reten-tion cysts, whose behavior is much more subtle, mucoceles cause local infl ammatory phenomena and sometimes bone resorption of adjacent structures. The treatment called for is surgical enucleation. The clinical case presented deals with a cystic lesion protruding through the non-cicatricial alveolus following a traumatic extraction performed weeks earlier. We also present the technique used to close the oroantral fi stula.

Perineal hernia extruding into the labium majus after multiple surgeries for pelvic organ prolapse.

A 78-year-old woman presented with a large bulge in the right labium majus. She had a previous history of two anterior and posterior vaginal wall prolapse repairs, a vaginal hysterectomy for uterovaginal prolapse, a sacrospinous ligament fixation for vaginal vault prolapse, and a LeFort partial colpocleisis for recurrent vault prolapse. Magnetic resonance imaging (MRI) revealed an anterior perineal hernia containing small bowel. Surgery was performed to close the pelvic floor defect through a perineal approach, and polypropylene mesh was used as a bolster. The hernial sac contained small bowel with very thin adhesions. Over 6 months of follow-up, there was no recurrence of the hernia or mesh complications. Perineal hernias after gynecological surgeries for benign diseases are rare. The indications for repair and the optimal surgical approach are not well described.

Spontaneous pulmonary hernia: a case report.

Hernia is defined as the protrusion of a totally or partially displaced organ from its normal visceral cavity. Most hernias occur at the level of the abdominal wall, because of a muscular defect. Pulmonary hernias are extremely rare and can be congenital or acquired. We present a 64-year-old patient who developed a spontaneous pulmonary hernia after a severe coughing episode. We describe the clinical features, diagnosis, and successful treatment.

[Right postpneumonectomy syndrome: case report]. / Síndrome postneumonectomía derecha: informe de un caso.

Postpneumonectomy syndrome is a rare entity in children. We report a case secondary to pneumonectomy performed due to an intrathoracic tumor. A 4-year-old boy with a history of right pneumonectomy and progressive respiratory distress, with extrinsic airway obstruction due to displaced mediastinal structures. There were failure to intubate the airway with endoluminal devices and impossibility of withdrawing from mechanical ventilation. As mediastinal repositioning was not possible, an aortic bypass with a prosthetic tube graft was performed, with favorable outcome and hospital discharge.
