Hernia obturatriz: Aspectos clínicos, imagenológicos y tratamiento / Obturator hernia: Clinical, imaging and treatment aspects

Introducción. Debido a la rareza de la hernia obturatriz y la imposibilidad para desarrollar estudios controlados de alto grado de evidencia, la mayoría de la literatura al respecto proviene de reportes de casos. Lo anterior, aunado al poco conocimiento del área anatómica de presentación y el cuadro clínico, la convierte en la hernia con mayor mortalidad. Métodos. Se realizó una búsqueda de la literatura en las principales bases de datos, ilustrado con pacientes manejados en el Servicio de Cirugía general de la Clínica Santa María de Sincelejo, Colombia. Discusión. La hernia obturatriz se puede descubrir en mujeres ancianas con antecedentes de cirugía abdominal o multiparidad. El signo de Howship­Romberg, que se presenta en la mitad de los pacientes, puede acompañarse de dolor abdominal en hipogastrio, vómitos y distensión progresiva. La radiografía de abdomen simple muestra tardíamente niveles hidroaéreos con ausencia de gas en ampolla rectal, pero como es poco específica para demostrar el sitio de obstrucción, es preferible la Tomografía computarizada. Conclusión. La hernia obturatriz requiere alto índice de sospecha, que ayude a la detección temprana e intervención quirúrgica inmediata, para evitar las complicaciones.

Introduction. Due to the rarity of the obturator hernia and the impossibility to develop controlled studies with a high degree of evidence, most of the reference in the literature comes from case reports. This, coupled with little knowledge of the anatomical area of presentation and clinical picture, makes it the hernia with the highest mortality. Methods. A literature search was carried out in the main databases, illustrated with patients managed in the General Surgery Service of the Clínica Santa María de Sincelejo. Discussion. Obturator hernia can be discovered in elderly women with a history of abdominal surgery or multiparity. The Howship ­ Romberg sign occurs in half of the patients, it can be associated with lower abdominal pain, vomiting, and progressive distension. Plain abdominal X-ray shows delayed air-fluid levels with absence of gas in the rectal ampulla, but since it is not very specific to demonstrate the site of obstruction, computed axial tomography is preferable. Conclusion. Obturator hernia requires a high index of suspicion, which helps early detection and immediate surgical intervention, to avoid complications.

Obstrucción intestinal por hernia obturatriz: serie de casos / Intestinal obstruction caused by obturator hernia: case series

OBJETIVO: Se presentan 3 casos de obstrucción intestinal por hernia obturatriz atascada, su manejo y una breve revisión de la literatura. MATERIALES Y MÉTODOSles y Métodos: Discusión del cuadro clínico, imágenes y manejo. Todos los casos fueron operados dentro del mismo día del diagnóstico y se confirmó la presencia de hernia obturatriz. El manejo de la hernia y su contenido fue ajustado a la situación de cada paciente. RESULTADOS: Los tres casos de hernia obturatriz aquí discutidos tienen la presentación clásica del cuadro, cuando se los revisa en forma retrospectiva y con imagenología compatible. Los tres pacientes evolucionaron en forma satisfactoria con alta precoz y control posoperatorio sin incidentes. Discusión: Nuestros 3 casos se condicen tanto en hallazgos clínicos, imagenológicos y en manejo con lo descrito en la literatura internacional. CONCLUSIÓN: La hernia del agujero obturatriz siendo infrecuente, se presenta en un tipo particular de pacientes y con sintomatología clásica. La tomografía axial computada es de gran ayuda y suele hacer el diagnóstico preciso en el preoperatorio. Es importante recordar este diagnóstico diferencial al momento de estudiar pacientes con obstrucción intestinal.

OBJECTIVE: 3 cases of intestinal obstruction that resulted in diagnosis of obturator hernia, their management and a brief international literature review are presented. MATERIAL AND METHODS: Discussion of the presentation, images, and management. In all cases surgery was performed the same day from the diagnosis of intestinal obstruction and confirmation of obturator hernia. The management of the hernia and it's content was adjusted to each patient's situation. RESULTS: Our 3 patients, when reviewed retrospectively, had the classic presentations and images of obturator hernia. All of them had a favourable evolution with an early discharge and no complications on follow up. DISCUSSION: Our 3 cases had clinical presentations and imaging studies that correlated well with international literature. CONCLUSION: Obturator hernia is an infrequent pathology, but appears in a particular type of patient and with classic presentation. Axial computed tomography is an important tool and usually makes the diagnosis previously to surgical exploration. It is important to consider this diagnosis when being faced with patients with intestinal obstruction.

Hernia obturatriz complicada. Conducta diagnóstica y terapéutica / COMPLICATED OBTURATOR HERNIA. DIAGNOSIS AND THERAPEUTIC MANAGEMENT

La hernia obturatriz tiene una baja incidencia, predomina en mujeres ancianas desnutridas, habitualmente con signos y síntomas poco específicos, situación que requiere resolución quirúrgica precoz para disminuir la morbi-mortalidad. Materiales y métodos: Análisis retrospectivo observacional sobre tres casos de oclusión intestinal por hernia obturatriz en el servicio de Cirugía General del Hospital Italiano de Córdoba entre el período comprendido desde enero de 2013 a diciembre de 2015. Resultados: Los tres pacientes fueron diagnosticados por TC en el preoperatorio, en dos se debió realizar resección intestinal y entero-entero anastomosis. Conclusión: la cirugía de urgencia es el tratamiento ideal

Obturator hernia is a rare type of hernia. Because of its low incidence, predominantly in elderly malnourished women, usually with non- specific signs and symptoms, diagnosis and treatment are often delayed. This situation requires early surgical treatment to prevent serious morbidity and mortality associated with this entity. Methods: Retrospective observational analysis of 3 cases of intestinal occlusion due to complicated obturator hernia at the Department of General Surgery, Hospital Italiano Córdoba, Argentina, between January 2013 to December 2015. Results: All three cases were diagnosed preoperatively by CT , but in two of the three cases it was due to perform an intestinal resection with anastomosis. Conclusion: The surgery performed early after admission, is the treatment of choice.

Un recorrido por la pared abdominal: evaluación de las hernias por tomografía computada multidetector / A tour of the abdominal wall: assessment of hernias by multidetector computed tomography

Si bien el diagnóstico de hernias de la pared abdominal es clínico y el estudio más indicado es la ecografía, en una gran cantidad de casos es difícil su evaluación o no se sospecha su presencia debido al biotipo del paciente, la ausencia de síntomas, la aparición de complicaciones o corresponde a algún tipo de hernia poco frecuente. Además, la debilidad de la pared abdominal generada por una cirugía predispone a la eventración de órganos, a veces poco habituales, como el hígado, la vejiga o el apéndice. La utilización de la tomografía computada multidetector (TCMD) brinda grandes ventajas cuando resulta dificultoso establecer el diagnóstico por otros métodos. También puede ser un hallazgo incidental a tener en cuenta por sus posibles complicaciones futuras. En el presente trabajo describimos los principales hallazgos por TCMD de las hernias y eventraciones de la pared abdominal (como la umbilical, epigástrica, hipogástrica, inguinal, de Spiegel, lumbar, obturatriz, intercostal e incisional) y su contenido.

Although the diagnosis of abdominal wall hernias is clinical, and the most appropriate study is ultrasound, in a lot of cases they are difficult to evaluate, or their presence is not suspected because of the biotype of the patient, the absence of symptoms, the presence of complications, or the appearance of rare hernias. Surgery weakness generated in the wall leads to organ hernia, sometimes unusual, as in the liver, bladder, or appendix. The use of multidetector computed tomography (MDCT) is a great advantage in these situations where the diagnosis can be difficult to determine with other methods. It also can be an incidental finding to consider eventual complications. In this paper, the main MDCT findings in abdominal wall hernias are described, including umbilical, epigastric, hypogastric, inguinal, Spiegel, lumbar, obturator, intercostal, and incisional, as well as their content.

Rol de la TC multicorte con RMP en el diagnóstico de la hernia obturatriz: presentación de un caso / Role of multislice CT with MPR (multi-planar reformation) in the diagnosis of obturator hernia. a case report

La hernia obturatriz (HO) es poco frecuente y representa del 0.05 al 0.4 por ciento del total de hernias. Debido a su rareza y a su presentación inespecífica, el diagnóstico es por lo general tardío y las tasas de mortalidad elevadas (12-70 por ciento). Se presenta un caso típico de HO diagnosticada en el preoperatorio mediante TC Multi-corte con RMP y tratado mediante laparotomía de urgencia con buen resultado. El empleo de TC Multicorte con RMP de abdomen y pelvis, en cuadros de obstrucción intestinal en mujeres añosas, sin antecedente de cirugías previas ni hernias objetivables, tiene gran valor para el diagnóstico preoperatorio precoz de HO y podría contribuir a reducir las elevadas tasas de morbilidad y mortalidad.

Abstract. The obturator hernia (OH) is rare and accounts for 0.05 to 0.4% of all hernias. Because of its rarity and its nonspecific presentation, diagnosis is usually late and has high mortality rates (12-70%). A typical case of OH diagnosed preoperatively by Multislice CT with MPR and treated using emergency laparotomy with good results, is presented. The use of Multislice CT with MPR of the abdomen and pelvis, in symptoms of intestinal obstruction in elderly women with no history of previous surgery or objectified hernias, has great value for early preoperative diagnosis of OH and could help reduce the high rates of morbidity and mortality.

Hérnia obturadora recidivada encarcerada: um relato de caso / Incarcerated recurrent obturator hernia: a case report

Objetivos: descrever a história, o diagnóstico e o tratamento de uma paciente com hérnia obturadora.Descrição do caso: uma paciente de 71 anos apresentou quadro de abdome agudo obstrutivo secundário a uma hérnia obturadora encarcerada e recidivada. O diagnóstico foi feito pela tomografia computadorizada e o tratamento foi cirúrgico, através da correção do defeito com colocação de tela de polipropileno em forma de cone.Conclusões: a hérnia obturadora é uma rara mas importante causa de obstrução intestinal. Por ser uma patologia incomum, seu diagnóstico normalmente é tardio, sendo realizado no transoperatório ou, menos frequentemente, através de tomografia computadorizada em avaliação pré-operatória de abdome agudo. Existem diversas formas para sua correção cirúrgica.

Aims: To describe the history, diagnosis and treatment of a patient with obturator hernia.Case description: A 72 years old woman presented with acute obstructive abdomen secondary to an incarcerated recurrent obturator hernia. The diagnosis was made by computed tomography and the treatment was surgical, by repairing the defect with placement of a polypropylene mesh in a cone shape (patch/plug).Conclusions: Obturator hernia is a rare, but important cause of intestinal obstruction. Because it is an uncommon patology, the diagnoses is usually delayed and is done during surgery or, less frequently, by computed tomography in the preoperative evaluation of acute abdomen. There are several strategies for its surgical correction.

Obstrucción intestinal por hernia obturatriz: caso clínico / Intestinal obstruction caused by an obturator hernia: report of one case

We report a 76 years old female presenting in the emergency room with a history of abdominal pain lasting seven days. A plain abdominal X ray showed few fluid filled loops. Due to persistence of pain and appearance of vomiting, an abdominal CAT sean showed a short bowel obstruction caused by an obturator hernia. The patient was operated, correcting the defect with a mesh. The postoperative evolution was uneventful.

La hernia obturatriz es una rara causa de obstrucción intestinal, se presenta en pacientes mujeres adultos mayores, desnutridos y postrados; se asocia a una elevada mortalidad por los antecedentes mórbidos de los pacientes y al bajo índice de sospecha. Se recomienda el uso de la tomografía axial computada como técnica de elección para el diagnóstico en pacientes con sospecha clínica. El objetivo de este trabajo es presentar un caso clínico de una paciente con hernia obturatriz que consultó en nuestro servicio de urgencia y se solicitó tomografía de abdomen y pelvis para completar estudio que requirió laparotomía exploradora ante el cuadro clínico y los hallazgos imagenológicos.

Diagnóstico y tratamiento de la hernia obturatriz: análisis de nuestra experiencia / Diagnosis and management of obturator hernia: analysis of our experience

Background: Obturator hernia is a rare type of hernia. Because symptoms and signs are non-specific, diagnosis and treatment are often delayed, increasing the rate of strangulation and mortality. Material and Methods: A retrospective study was performed in 17 cases of obturator hernia at Ramón y Cajal Hospital between January 1986 and December of 2007. Results: All patients were women with a mean age of 77 years (range 19-88 years). Mean time from onset of symptoms to surgery was 3 days (range 0-10 days). Howship-Romberg sign was positive in five cases (29,4 percent). Emergency surgery was performed in 16 cases (94 percent) and elective surgery in one (6 percent). CT has increased the rate of preoperative diagnosis from 16,6 percent to 41,2 percent, however, the rate of strangulation of bowel was 47 percent, requiring intestinal resection ten patients (59 percent). Hernia repair was performed using polypropylene mesh in 8 cases (47 percent) and by means of simple suture and apposition of the peritoneum in the rest 9 cases. Mean hospital postoperative stay was 11,65 days (range 4-26 days) and mortality was 23,5 percent. Conclusion: Although CT sean has facilitated us the correct diagnosis of obturator hernia, decreasing the mean time from onset of symptoms to surgery to 3 days, we could not reduce the rate of intestinal resection and mortality.

La hernia obturatriz es una entidad rara, con frecuente ausencia de signos y síntomas específicos, lo que retrasa su diagnóstico y tratamiento, y por ello puede presentar una elevada tasa de estrangulación y mortalidad. Material y Métodos: Efectuamos un estudio retrospectivo sobre 17 casos de hernia obturatriz en el Hospital Ramón y Cajal entre enero de 1986 y diciembre de 2007. Resultados: Todos los pacientes eran mujeres con una edad media de 77 años (rango 19-88 años). El tiempo medio desde el inicio de los síntomas hasta la cirugía fue de 3 días (rango 1-10 días). El signo de Howship- Romberg fue positivo en 5 casos (29,4 por ciento). Se efectuaron 16 intervenciones con carácter de urgente (94 por ciento) y una de forma electiva (6 por ciento). La realización de un TAC va a incrementar la tasa de diagnóstico preoperatorio de un 16,6 por ciento a un 41,2 por ciento. La tasa de estrangulación fue de 47 por ciento, requiriendo resección intestinal 10 pacientes (59 por ciento). En 8 ocasiones se reparó el defecto hemiario con una malla de polipropileno (47 por ciento), siendo con cierre simple y aposición del peritoneo en los 9 restantes. La estancia media postoperatoria fue de 11,65 días (rango 4-26 días) y la tasa de mortalidad de 23,5 por ciento. Conclusión: Aunque la realización del TAC ha incrementado la tasa de diagnóstico preoperatorio, disminuyendo el tiempo desde la aparición de los síntomas hasta la cirugía a 3 días, no hemos podido reducir la tasa de resección intestinal y mortalidad.

The Obturator Hernia: A Challenge for Early Diagnosis with Computed Tomography in Emergency Situations

Obturator hernias usually occur in elderly persons. We sometimes miss the correct diagnosis because of vague symptoms and signs in older patients at initial presentation. For good clinical outcomes, we should make the correct diagnosis earlier, especially in aged patients. Here we report cases of obturator hernia in two aged patients without specific medical or surgical histories. Two older women suffered obturator hernias, which were characterized by clinical and radiographic features. They did not have any specific surgical and medical histories. For further evaluation of abdominal symptoms and signs, we did an abdominopelvic computed tomography (CT) scan in the emergency department. The CT scan revealed findings compatible with an obturator hernia in the area of the obturator foramen. They were treated and discharged without complications. When obturator hernia is suspected in a patient with related symptoms and signs, early CT scans should be considered to detect obturator hernia.

Experiences on Obturator Hernia and Review of Korean Cases

PURPOSE: We performed this study to share experiences in the management of obturator hernia, which is a very rare disease among elderly women, because rarity of this disease will not approve an expert institute or surgeon and because the aging society, Korea, can increase the incidence. METHODS: Patient characteristics, clinical manifestations and treatment results were retrospectively collected from the 12 obturator hernia patients since 2000 in the three hospitals of the authors. Twenty-one obturator hernia cases reported in the Korean literatures were reviewed. In addition, we analyzed clinical features and treatment results of the total 33 patients, collectively. RESULTS: Most of the patients were elderly women except one young, poorly nourished, male patient with pulmonary tuberculosis. Their mean age was 79.6 years. Sixty-four percent (21/33) of the patients had preoperative morbidity. Symptoms from the compression of the obturator nerve, which is an important clue to the diagnosis, were observed in 67% (22/33). Interestingly, spontaneous or suspicious-spontaneous reductions were reported in 7 (21%) patients. Abdominal CT scan was the major tool for diagnosis. Abdominal approach alone could successfully manage most cases, though 84% (27/32) needed anastomosis of the bowel. Operative mortality was 2 of the 32 cases but morbidity was 44% of the 32 patients and the mean hospital period after operation was 21 days. CONCLUSION: Management of patients with obturator hernJd surgical management and proper peri-operative care as well as appropriate managing the families is essential for improved results.

Successfully Treated Obturator Hernia in Spite of Delayed Operation

Obturator hernia is a rare type of pelvic hernia and occurs most commonly in elderly and debilitated women. It is still a challenge for surgeons to diagnose precisely in early stages because of its nonspecific symptoms and consequently delayed diagnosis could lead to high morbidity and mortality. We experienced a 92-year old patient who was diagnosed as obturator hernia which was confirmed by computed tomography scan of the abdomen and pelvis. The operation was delayed due to the refusal of family members but eventually done after 12 days from initial diagnosis. After manual reduction of small bowel impacted into right obturator foramen, segmental resection of impacted small bowel and anastomosis was done. The hernial defect was closed by primary closure with Dexon suture material. After the operation, the patient was discharged without significant complications. We report here successful results of delayed operation for obturator hernia.

Incarcerated Obturator Hernia: The Need of Herniorrhaphy in Self-reduced Obturator Hernia

An obturator hernia is an exceptionally rare form of hernia. It occurs mostly in elderly, thin, multiparous, and emaciated women. Correct diagnosis and treatment is important because delayed treatment can lead to a higher mortality rate. Recently, we experienced two cases of mechanical small bowel obstruction due to incarcerated obturator hernia. One of these patients was an 83-year-old woman who was diagnosed with left incarcerated obturator hernia by computed tomography (CT). The patient's symptom disappeared abruptly. A recheck CT scan revealed self-reduction of the obturator hernia, and the patient refused operation. Two weeks later, the patient was presented again to the emergency clinic with incarcerated small bowel in the left obturator hernia, which was seen on CT. The other patient was a 79-year-old woman who had a 2-day history of abdominal pain. She was diagnosed with a right obturator hernia by CT. Both patients were treated without bowel resection.

Obturator hernia.

An elderly emaciated female patient presented with recurrent lower abdominal pain associated with nausea and vomiting due to obstruction of the small bowel. Although the Howship-Romberg sign and tender mass on digital rectal examination could not ascertained but plain X-ray abdomen shows features of acute intestinal obstruction. After resuscitation laparotomy was done and diagnosed as case of strangulated obturator hernia of Ricters type. Reduction of hernial content and resection of the gangrenous part of small bowel with end-to-end anastomosis done. The hernial defect is repaired by a proleine mesh. Abdomen closed in layers keeping a drain in right iliac fossa and pelvic cavity. The postoperative recovery was uneventful. Patient discharge with advice on 9th postoperative day.

Totally Extraperitoneal Laparoscopic Repair of Obturator Hernia withPartial Intestinal Obstruction

Obturator hernia is a rare variety of pelvic hernia. The diagnosis frequently is delayed and may be accompanied by dehydration, acute abdominal distress and small bowel strangulation. We report a case of totally extraperitoneal repair of obturator hernia with partial intestinal obstruction. An eighty-two-year old female with intermittent abdominal pain was diagnosed with obturator hernia with partial intestinal obstruction. We did total extraperitoneal laparoscopic repair of the obturator hernia with polypropylene mesh. Total extraperitoneal laparoscopic repair for obturator hernia is a safe and effective treatment.

Obturator hernia in an ageing society

<p><b>INTRODUCTION</b>Obturator hernia is an important cause of small bowel obstruction and is associated with difficult diagnosis and high mortality.</p><p><b>MATERIALS AND METHODS</b>We reviewed 22 cases of intestinal obstruction due to obturator hernia that necessitated surgical intervention over the last 17 years and evaluated the changes in the number of patients based on the census data.</p><p><b>RESULTS</b>All cases were elderly females. The Howship-Romberg sign was present in 15 patients (68%). Computed tomography (CT) correctly diagnosed 13/15 (87%) of cases in which it was performed prospectively. The median time to surgery was 7.5+/-5.2 days for those patients with bowel resection, compared to 0.8+/-1.3 days for those without (P <0.05). The number of patients with obturator hernia has increased with an ageing society.</p><p><b>CONCLUSIONS</b>The rising incidence of obturator hernia is probably linked to an ageing society. CT of the pelvis was helpful in obtaining the correct diagnosis. The shorter the delay between admission and surgery, the lower the bowel resection rate. Laparotomy at an early stage is recommended in such patients as it leads to reduced morbidity and mortality.</p>

Sixty-one cases of obturator hernia in Chiangrai Regional Hospital: retrospective study.

OBJECTIVE: To review the patient characteristics and clinical symptoms, intraoperative finding and management, including morbidity and mortality rate of obturator hernia cases. MATERIAL AND METHOD: A retrospective study was performed in 61 patients diagnosed as obturator hernia at Chiangrai Regional Hospital between January 2000 and December 2005. RESULTS: The incidence of obturator hernia is 61 of 2,828 cases (2.2%) of all hernias, female:male 6.6:1. The mean age was 72.85 years. The mean body weight was 35.72 Kg. Howship-Romberg's sign were positive in eight patients (13.11%). Thirty-five patients (57.38%) were Richter type hernia, left:right side 3:2. Strangulation of bowel occurred in 41 patients (67.21%) Mortality rate was 11.47%. All patients with postoperative complications and all deaths showed bowel strangulation and all were more than 70 years of age. CONCLUSION: In the present study, the authors found a high incidence of obturator hernia (2.2% of all hernias) compared with a previous report (0.05%-1.4% of all hernias). This high incident rate might relate to the specific local life style of people in Chiangrai as most patients had a habit of smoking. Chronic obstructive pulmonary disease (COPD), old age, and low body weight were possible contributing factors. Bowel strangulation and age more than 70 years old were associated with morbidity and mortality.

Small Bowel Obstruction due to Incarcerated Obturator Hernia

An obturator hernia is a rare but important cause of small bowel obstruction, due to the difficulty of its diagnosis and the high mortality rate. Elderly, multiparous and debilitated women with comorbid illnesses are most often affected, and this hernia, coupled with a delay in the diagnosis and operative intervention, results in the high mortality rate, which represents both diagnostic and therapeutic challenges to the surgeon. Recently, we experienced two unusual obturator hernia cases, where incarceration had lead to a small bowel obstruction. One patient was an 82-year-old woman with a compression fracture of the lumbar spine, which presented with left inguinal pain and abdominal distension. The abdominal plain X-ray showed evidence of a small bowel obstruction. The hernia was diagnosed by a computed tomography (CT) scan and repaired using the lower midline transperitoneal approach. To prevent a recurrence, the hernial defect was enforced with a polypropylene plug and mesh. The other patient was a 92-year old woman with fracture of the neck of the left femur, which presented with defecation difficulty and abdominal distension. The abdominal plain X-ray showed multiple distended small bowel loops consistent with small bowel obstruction. A contrast-enhanced CT scan of the abdomen and pelvis showed a right obturator hernia with strangulation. We recommended an emergency operation, but the patient refused the operative procedure. With on going conservative management, the symptom was fortunately resolved. Herein, we report these findings with a brief review of the literature.

Incidence of corona mortis; preperitoneal anatomy for laparoscopic hernia repair.

The present study 66 half pelvis of cadaver for vascular structure called corona mortis, vessel that connect between external iliac and internal iliac system. The vessel was found 77.27% and the incidence of aberrant is 13.6%. The average distance from symphysis pubis to the vessel is 5.28 cm and distance above superior pubic rami is 1.37 cm.
