Congenital Mesenteric Defect with Transmesenteric Hernia in Children: A Case Series.

ABSTRACT: Transmesentric hernias are a type of internal hernia, in which there is herniation of bowel loops through a defect in the mesentery. They present with a wide variety of symptoms without any specific radiological features, leading to a delay in diagnosis and high mortality rate. Here, we present a case series of four patients with this rare but fatal cause of small bowel obstruction. Three children presented to the emergency department with small bowel obstruction. The other baby was a preterm neonate with an antenatal scan showing small bowel obstruction. All children underwent emergency laparotomy and were found to have a mesenteric defect with herniation and gangrene of the small bowel. Resection anastomosis of the gangrenous segment and closure of the mesenteric defect were done. The differential for small bowel obstruction in children should include transmesentric hernia. Laboratory or imaging investigations are often inconclusive. Timely exploration can save lives in this rare but life-threatening condition.

Diagnostic value of high-resolution ultrasound combined with multi-slice computer tomography (MSCT) for pediatric intra-abdominal hernias: a retrospective study.

INTRODUCTION: To explore the diagnostic value of high-resolution ultrasound combined with multi-slice computer tomography (MSCT) for pediatric intra-abdominal hernias (IAHs), and to analyze the potential causes for missed diagnosis and misdiagnosis of IAHs in children. METHODS: A retrospective analysis was conducted on 45 children with surgically confirmed IAHs. The diagnostic rate of IAHs by preoperative high-resolution ultrasound combined with MSCT was compared with that of intraoperative examination, and the potential causes for missed diagnosis and misdiagnosis by the combination method were analyzed. RESULTS: Forty-five cases of pediatric IAHs were categorized into primary (25/45, 55.5%) and acquired secondary hernias (20/45, 44.5%). Among children with primary hernias, mesenteric defects were identified as the predominant subtype (40%). Acquired secondary hernias typically resulted from abnormal openings in the abdominal wall or band adhesions due to trauma, surgery, or inflammation. In particular, adhesive band hernias were the major type in children with acquired secondary hernias (40%). The diagnostic rate of high-resolution ultrasound was 77.8%, with "cross sign" as a characteristic ultrasonic feature. Among 10 cases of missed diagnosis or misdiagnosis, 5 were finally diagnosed as IAHs by multi-slice computer tomography (MSCT). Overall, the diagnostic rate of pediatric IAHs by preoperative ultrasound combined with radiological imaging reached 88.9%. DISCUSSION: IAHs in children, particularly mesenteric defects, are prone to strangulated intestinal obstruction and necrosis. High-resolution ultrasound combined with MSCT greatly enhances the diagnostic accuracy of pediatric IAHs.

Spigelian hernia.

INTRODUCTION: Spigelian hernia is a rare type of abdominal wall hernias which are often diagnosed when incarcerated. These hernias typically develop at the crossing point of the arcuate line and lateral portion of rectus abdominis muscle. CASE REPORT: We present the case of a 44-year-old female patient admitted to our surgery unit for a painful lump in her right mesogastrium. Incarcerated atypical hernia in the right mesogastrium was suspected based on completed imaging assessments. Spigelian hernia was confirmed by preoperative findings. Interestingly, the patient applied interferon (multiple sclerosis therapy) at the site of the lump, which is why the diagnosis of lipodystrophy had been considered. CONCLUSION: In general, the diagnosis of Spigelian hernia is difficult. From the anatomical point of view the clinical finding is not always specific. The risk of incarceration is relatively high, and thus even clinically silent findings are indicated for surgery.

A rare case of abdominal cocoon associated with internal hernia in an adult.

A transmesenteric internal hernia (TIH) is a protrusion of a viscus through the mesenteric defect. It is secondary to previous gastrointestinal surgery in an adult. Early diagnosis and management are warranted to prevent the strangulation of the bowel in a TIH. Here, we are reporting a case of a 24-year-old gentleman with COVID-positive status who has presented with cough, abdominal cocoon, and features of subacute intestinal obstruction (SAIO) without any previous history of abdominal surgery. A nonoperative trial is given in the management of abdominal cocoon with SAIO. In contrast, delay in surgical intervention in TIH leads to bowel gangrene. Surprisingly even on contrast-enhanced computed tomography of the abdomen, TIH was not picked up. We have diagnosed this case intraoperatively with gangrene of the bowel. In an abdominal cocoon without any history suggestive of tuberculosis or previous surgery, or any other condition that leads to an intra-abdominal reaction, an internal hernia should be kept as a differential diagnosis. The delay in diagnosis and surgical intervention is associated with potentially disastrous complications.

Evaluation and clinical significance of predictors for strangulation and intestinal resection in emergency anterior abdominal wall hernia surgery.

BACKGROUND: Emergency anterior abdominal wall hernia surgery plays a pivotal role in emergency general surgery practice. In this study, the predictive value of laboratory and imaging findings as well as demographic information and comorbidities of the patients for the recognition of strangulation and intestinal resection was investigated. METHODS: Patients over the age of 18 who were operated consecutively with an indication for emergency anterior abdominal wall hernia surgery between January 2017 and December 2019 in a single tertiary hospital were included in this retrospective cohort study. The patient population was divided into two groups according to the pre-operative findings during the emergency anterior abdominal wall hernia surgery. Group 1 consisted of cases with incarceration but without strangulation, whereas Group 2 consisted of cases with strangulation in addition to incarceration. Moreover, in evaluation for the requirement for intestinal resection, patient Group 2 was divided further into two groups, namely, as Group (1 or 2) a and Group (1 or 2) b, defining the need for intestinal resection. RESULTS: A total of 106 patients who had emergency anterior abdominal wall repair surgery due to incarcerated hernias were included in the study. The evaluation of the indices related to systemic inflammation revealed that lactate dehydrogenase to white blood cell ratio was significantly lower but neutrophil to platelet and neutrophil to albumin ratios were significantly higher in patients with strangulation, showing the significance of those systemic inflammation indices in detecting strangulation (p=0.027, p=0.035 and p=0.030, respectively). Moreover, the analysis of the patients in whom intestinal resection was required (Group 2a vs. 2b) exposed that neutrophil to albumin ratio was significantly higher in the patients with intestinal resection (p=0.036). CONCLUSION: Indices of systemic inflammation such as lactate dehydrogenase to white blood cell ratio, neutrophil to platelet ratio, and particularly neutrophil to albumin ratio may be potentially beneficial to prevent complications and improve clinical outcomes in emergency hernia surgery.

Retrocecal hernia with small bowel obstruction: a review of literature.

Retrocecal hernia, a type of internal hernia, is a rare cause of small bowel obstruction. It can come as a surprise to the operating surgeon if not diagnosed preoperatively. We hereby report a case of retrocecal hernia presenting with small bowel obstruction. A man in his early 60s presented to the emergency department with recurrent episodes of vomiting associated with abdominal pain for 3 days and the inability to pass flatus for 1 day. Preoperative imaging revealed multiple air-fluid levels with a transition point in the terminal ileum suggestive of small bowel obstruction. After adequate resuscitation, emergency laparotomy was performed, and intraoperatively, herniated ileal loop through a retrocecal defect was identified as a cause of obstruction. Herniated ileal loop was reduced, followed by the closure of the defect and cecopexy. The postoperative course was uneventful, and the patient was discharged in a stable condition. He was asymptomatic on follow-up.

Multiple Internal Hernias: A Complication of Laparoscopic Roux-en-Y Gastric Bypass.

Introduction: Internal hernias are the most common cause of small bowel obstruction following laparoscopic Roux-en-Y gastric bypass surgery (LRYGBP) with four distinct types. Herein, we report the clinical course of a patient with two independent hernias at the Petersen's space and a rarer subtype at the jejunojejunal window. A high index of suspicion for less common subtypes of internal hernias and the possibility of multiple, simultaneous internal hernias is critical. Case Description: We describe the case of a 52-year-old female with a history of LRYGBP who presented with abdominal pain and emesis due to an internal hernia at Peterson's defect, requiring subsequent laparoscopic repair. On postoperative day three, the patient presented again with recurrent abdominal pain and emesis. Repeat exploratory laparoscopy found a separate internal hernia involving the jejunojejunal window with the previously repaired Petersen's defect intact. Discussion: This case illustrates a unique scenario of a patient post-LRYGBP with multiple internal hernias at the Peterson's space and the less common jejunojejunal window, which was missed during the index surgery. Failure to identify simultaneous hernias may result in additional invasive intervention and further morbidity. Conclusion: Multiple less-common variants of internal hernias may present simultaneously following LRYGBP.

Acute abdomen due to strangulated intravesical hernia with incidental finding of kidney tumor: A case report and literature review.

Internal supravesical hernia is a rare type of internal abdominal hernia with overall incidence <4% of all internal abdominal hernias. The clinical diagnosis is a major preoperative diagnostic challenge for both the surgeon and the radiologist. It is a rare cause of small bowel obstruction, but in case of strangulation it can be fatal and it necessitates urgent surgical intervention. In this case study, we report a case of intravesical type of supravesical hernia in a 63-year-old man with acute intestinal obstruction and an accidental finding of a kid-ney tumor. In the article, we discuss the clinical picture, diagnosis, risk factors, treatment strategy and complications of this rare entity.

Hernia de Garengeot / Garengeot's Hernia

Introducción: La hernia de Garengeot es una de las hernias de la pared abdominal más infrecuente del mundo. Objetivo: Presentar una paciente con diagnóstico de hernia crural, con el apéndice cecal, lo cual constituye la hernia de Garengeot. Caso clínico: Paciente femenina de color de piel blanca, de 56 años de edad, con antecedentes de salud, que ingresó en el Servicio de Cirugía del Hospital Universitario "Manuel Ascunce Domenech" con el diagnóstico de hernia crural atascada. Presentó dolor en la raíz del muslo derecho, náuseas y presencia de una tumoración por debajo de la línea de malgaigne, irreductible. Conclusiones: La hernia de Garengeot es una entidad quirúrgica única, difícil de distinguir de una hernia crural irreductible. Por tanto, su diagnóstico es un hallazgo intraoperatorio y la herniorrafia es el proceder quirúrgico más empleado(AU)

Introduction: Garengeot's hernia is one of the most uncommon abdominal wall hernias worldwide. Objective: To present the case of a patient with a diagnosis of crural hernia, with cecal appendix, definitely being Garengeot's hernia. Clinical case: A female patient of white skin color, aged 56 years old, with a family history of disease, was admitted to the surgery service of Hospital Universitario "Manuel Ascunce Domenech" with the diagnosis of incarcerated crural hernia. He presented pain in the root of the right thigh, nausea and an irreducible tumor below the Malgaigne's line, irreducible. Conclusions: Garengeot's hernia is a unique surgical entity, difficult to distinguish from an irreducible crural hernia. Therefore, its diagnosis is an intraoperative finding and herniorrhaphy is the most commonly used surgical procedure(AU)

Small Bowel Obstruction Caused by Spontaneous Transomental Hernia: A Case Report.

An internal hernia is a protrusion of visceral contents through a defect in the mesentery or peritoneum. Small bowel obstruction is a common clinical presentation of internal hernias, accounting for 4.1% of all intestinal obstructions. Transomental hernia is a rare type of internal hernia (1-4% of internal hernias), with non-specific symptoms, making its preoperative diagnosis difficult. It is strangulated more frequently, and the postoperative mortality rate is high (30%). Therefore, early diagnosis and management are crucial. We report a case of a 77-year-old female who presented with small bowel obstruction, and a suspected incarcerated internal hernia on abdomen-pelvis CT. A spontaneous transomental hernia was confirmed on emergency laparotomy.

Hernia de Spiegel: a propósito de un caso / Spiegel Hernia. About a case

Presentamos el caso de una mujer de 86 años con una hernia espigeliana complicada por la oclusión intestinal, cuyo diagnóstico se basó en semiología y tomografía computarizada. En la anamnesis, informó dolor en la fosa ilíaca derecha asociada con los vómitos. El examen físico mostró una masa dura, sensible y móvil ubicada en la fosa ilíaca derecha. La tomografía computarizada abdominal mostró un saco hernial de 13 mm con un cuello en la fosa ilíaca derecha, frente a la aponeurosis del músculo oblicuo externo. Eso contenía grasa y un bucle de intestino delgado. El diagnóstico de hernia espigeliana atascada. La cirugía se realizó con un manejo postoperatorio simple.

In the anamnesis, he reported pain in the right iliac fossa associated with vomiting. Physical examination showed a hard, sensitive, and mobile mass located in the right iliac fossa. abdominal computed tomography showed a 13-mm hernial sac with a neck in the right iliac fossa, in front of the aponeurosis of the external oblique muscle. That contained fat and a loop of small intestine. The diagnosis of stuck Spigelian hernia. The surgery was performed with simple postoperative management

Ruptured Ovarian Cyst Masking Diagnosis of Hernia Through Broad Ligament of Uterus: A Case Report.

Small bowel obstruction is a common surgical emergency and frequent cause of hospitalization. Internal hernias account for less than 6% of all small bowel obstruction cases. Less frequently, hernias through the broad ligament of the uterus can occur and account for only 4-7% of total internal hernia cases. We report a case of a small bowel hernia through broad ligament of the uterus in a young female. Multiple diagnostic modalities suggested a ruptured ovarian cyst as the most probable cause for her abdominal pain. However, her symptoms were much more severe than an ovarian cyst would normally produce. Therefore, a diagnostic laparotomy was performed, which found a small intestine hernia through the left broad ligament of the uterus. The diagnosis of intestinal hernias, specifically through the broad ligament, is often delayed due to the infrequent occurrence, varied presentation, and difficulty of confirmation on computed tomography (CT) scan. Surgery is the gold standard for the diagnosis and treatment of internal hernias. This article draws attention toward a rare and potentially life-threatening cause of abdominal pain.

Traumatic Spigelian Hernia in a Pediatric Patient Following a Bicycle Injury.

Blunt abdominal trauma due to bicycle accident is a common occurrence in the pediatric population; however, traumatic abdominal wall hernia as the result of blunt trauma is a rare presentation. Abdominal wall injuries can be isolated or associated with multiple intra-abdominal pathologies. A high index of suspicion is essential for prompt intervention, especially when there is concurrent intra-abdominal pathology. We present a case of a traumatic spigelian hernia in a pediatric patient following a handlebar injury with the intraoperative discovery of a bucket-handle type mesenteric injury to the jejunum.

Manual Closed Reduction of Incarcerated Hernia: Is It Safe in the Emergency Department?

BACKGROUND: Emergency surgical repair is the standard approach to the management of an incarcerated abdominal wall hernia (IAWH). In cases of very high-risk patients, manual closed reduction (MCR) of IAWH may prevent the need for emergency surgery. OBJECTIVES: To evaluate the safety, success rate, and complications of MCR in the management of IAWH conducted in an emergency department. METHODS: The data of all patients who underwent MCR between 2012 and 2018 were retrospectively collected. Patient demographics, presenting symptoms, clinical parameters, and management during the hospitalization were retrieved from the medical charts. RESULTS: Overall, 548 patients underwent MCR during the study period. The success rate was 25.4% (139 patients). One patient had a complication that required a laparotomy 2 days after his discharge. A recurrent incarceration occurred in 23%, 60% of them underwent successful repeated MCR and the others underwent emergency surgery. Six patients (1.4%) had a bowel perforation after a failed MCR. CONCLUSIONS: MCR can be performed safely in the emergency department and should be consider as an option to treat IAWH, especially in high operative risk patients.

Primary defect of ileal mesentery presenting as internal herniation and strangulation of the small bowel: Case report.

Primary internal hernia is a rare entity of acute intestinal obstruction. Delay in diagnosis and surgical intervention can cause ischaemia or gangrene of the small bowel and result in high morbidity and mortality. A 14-year-old boy presented to the emergency department with acute intestinal obstruction. On exploration, 3-4cm mesenteric defect was noted in the ileal region. Strangulated loops of the small bowel had gone through the mesenteric defect in a complicated way. Primary anastomosis was done after resection of the gangrenous small bowel.

Left paraduodenal hernia: a rare cause of recurrent abdominal pain: case report.

Internal hernias are quite rare, accounting for fewer than 1% of all abdominal hernias. Moreover, the most frequent cause of internal herniation is paraduodenal hernia (PDH). Diagnosing paraduodenal hernias can be difficult due to the wide range of symptoms that can occur. It is a case report of paraduodenal hernia that was diagnosed and managed in a tertiary center. We describe the case of a 55-year-old male patient who had been experiencing nonspecific abdominal discomfort for the last 5 years and had several comorbidities and positive serology. An abdominal computed tomography (CT) revealed that he had a left PDH, which was effectively treated with laparoscopic surgical repair. The study's strength is that it was correctly identified by CT and subsequently laparoscopically corrected. A gastrografin swallow study was also performed postoperatively to ensure there was no leak. The study's flaw is that the patient was misdiagnosed for five years in other medical facilities. Because paraduodenal hernia is an uncommon diagnosis, it's important to keep it in mind as one of the differential diagnoses for persistent discomfort. It also needs accurate imaging in order to identify and successfully manage it. To demonstrate the relevance of this uncommon condition, future research is needed to report on any misdiagnosis or treatment. To conclude, nowadays the best option for paraduodenal hernia repair is laparoscopic surgery. However, because it can present with a wide variety of symptoms and diagnosis might be challenging, it demands a high index of suspicion. The gold standard for identifying paraduodenal hernia is still a CT scan of the abdomen. Patients who are stable and have no signs of intestinal obstruction might decide to have their hernia repaired to avoid future problems. To demonstrate the relevance of this uncommon condition, future research is needed to report on any misdiagnosis or treatment.
