Amyand's hernia: a report of 18 consecutive patients over a 15-year period

Amyand's hernia: a case report

An Amyand's hernia is a type of inguinal hernia where the appendix protrudes into the hernial sac. Pre-operative diagnosis is clinically challenging and ultimately the diagnosis is made intra-operatively. We report on a 75-year-old lady who presented with abdominal pain and a lump in her right groin region. She proceeded to theatre and had a diagnostic laparoscopy where she was diagnosed with an Amyand's hernia. The appendix was mildly inflamed and there was an ischemic appearance of the mesoappendix. According to the guidelines proposed by Losanoff and Basson she subsequently underwent a successful laparoscopic appendicectomy and primary repair of the hernia.

Management of Perforated Appendicitis in Amyand's Hernia: A Multidisciplinary Approach to Complex Postoperative Complications

Amyand's hernia is an exceptionally rare condition in which the appendix is located within an inguinal hernia sac. While it is typically asymptomatic, the occurrence of appendicitis or perforation within these hernias presents significant diagnostic and therapeutic challenges. We report a unique case involving a 31-year-old male patient who developed perforated appendicitis within an Amyand's hernia, resulting in severe intra-abdominal infection and complex postoperative complications, including the formation of multiple abscesses at three different sites. A multidisciplinary approach, involving general surgery, infectious disease, interventional radiology (IR), and urology, was crucial for effective source control and infection management. This case underscores the importance of individualized surgical decision-making in cases of Amyand's hernia with significant inflammatory involvement, emphasizing the necessity for timely recognition and intervention to minimize complications and improve patient outcomes.

Strangulated Amyand's hernia with testicular necrosis in an adult: A case report

INTRODUCTION

Amyand's hernia is a rare condition defined by the presence of the vermiform appendix within an inguinal hernia sac. The occurrence of Amyand's hernia with testicular necrosis is particularly uncommon, further complicating its clinical presentation and management.

CASE PRESENTATION

A 50-year-old male presented with a two-year history of progressive right scrotal swelling, acutely worsened over four days with pain and fever. Examination revealed a firm, tender, irreducible right scrotal mass with overlying erythema. Laboratory tests showed leukocytosis. Imaging confirmed an inflamed appendix within the hernial sac, consistent with Amyand's hernia complicated by abscess formation. Emergency surgery revealed a gangrenous appendix, scrotal abscess, and necrotic right testicular tissue. The patient underwent appendectomy, orchiectomy, hernia repair, and abscess drainage. He recovered uneventfully, with symptom resolution and no recurrence at follow-up.

DISCUSSION

The progression of Amyand's hernia to appendicitis and subsequent perforation, as seen in our case, can result in severe complications, including abscess formation and testicular necrosis. The Losanoff and Basson classification categorizes Amyand's hernia based on the appendix's condition and associated complications, ranging from a normal appendix (Type 1) to severe extra-sac pathology such as gangrene or malignancy (Type 4). Our case aligns with Type 4, involving a perforated appendix with gangrene and a scrotal abscess, necessitating extensive surgical intervention.

CONCLUSION

This case highlights the rarity and complexity of Amyand's hernia in adults, emphasizing the need for prompt recognition and tailored management to achieve favorable outcomes.

Amyand's hernia and associated acute appendicitis: A case report

INTRODUCTION

Amyand's hernia is incarceration of vermiform appendix within inguinal hernia. Amyand's hernia associated with acute appendicitis is rare.

CASE PRESENTATION

A male in his 5th decade of life presented with enlarged right reducible inguinal scrotal swelling and each episode of incarceration relieved manually. Background history of a movement disorder. Ultrasound reported right inguinoscrotal hernia with bowel content but no obstruction seen with plain abdominal x-ray. Elective right open inguinoscrotal repair was done. Intraoperative findings included enlarged superficial ring, enlarged hyperemic appendix in indirect hernia sac adhering to caecum. After appendectomy, the sac was transfixed above caecum. Hernioplasty was done with a polypropylene, poliglecaprone 25, macroporous and partially absorbable mesh. Immediate post-operative period was uneventful. Last review at 7 months showed no complication.

CLINICAL DISCUSSION

About 1 % of inguinal hernias retain part or whole appendix. In Amyand's hernia, 0.07-0.13 % of appendix is more prone to trauma, impaired vascular supply, inflammation, and microbial multiplication. Index patient's appendix was inflamed and histology confirmed focal acute transmural inflammation and denudation of appendiceal epithelial walls. Mesh repair is generally contraindicated in appendicitis or ruptured appendix but no post-operative complication occurred in index patient up to 7 months after appendectomy via the hernia with mesh repair.

CONCLUSION

Amyand's hernia with acute appendicitis is rare. Though use of mesh during surgery is controversial, hernioplasty was done in index patient because of the predisposing history of a movement disorder and recurrence rate of herniorrhaphy.

Management of a Patient With an Obstructed Inguinal Hernia With Amyand's Variety: A Report of a Rare Case With a Review of the Literature

Amyand's hernia is a rare form of inguinal hernia, where the appendix is located within the inguinal sac. A 66-year-old male presented with an obstructed, incarcerated right inguinal hernia. He underwent an emergency herniotomy under spinal anesthesia. Intraoperatively, the hernia sac contained a viable small bowel and part of the appendix. As the appendix appeared mildly inflamed, an appendicectomy was performed, and a synthetic mesh repair was done. He received a postoperative course of antibiotics and was discharged home on day 3 after an uneventful recovery. Histology of the appendix revealed a fecolith in the absence of acute inflammation. He did not have any procedure-related complications on follow-up. Preoperative diagnosis of Amyand's hernia is a challenge due to nonspecific symptoms and rarity. Lasanoff and Basson classify Amyand's hernia and provide surgical guidance for its management. Our case belonged to the type 2 category. Management of Amyand's hernia needs an individually tailored approach rather than strict adherence to conventional guidelines. The presence of an appendicular fecolith in the absence of inflammation provides an interesting area to explore in an Amyand's hernia.

Appendicitis Within an Incarcerated Inguinal Hernia Presenting as Acute Testicular Pain: A Case Report

Testicular pain is a common complaint in emergency departments, with a wide range of underlying pathologies. Incarcerated inguinal hernias are an emergent and often overlooked cause of testicular pain, necessitating prompt diagnosis and management. These cases can be complex, especially when the hernia contents obscure the clinical picture. Here, we present the case of a 34-year-old male patient who presented with testicular pain and swelling, ultimately diagnosed with appendicitis within the scrotum. This appendicitis led to an incarcerated inguinal hernia requiring emergent surgical intervention. The patient had an uneventful postoperative course and remained well at the two-month follow-up.

Unilateral Concurrent Amyand's Hernia and Inguinal Bladder Hernia (IBH): A Case Report

An inguinal hernia is a common surgical condition where abdominal contents protrude through a weakened area of the abdominal wall. While most are straightforward, rare variants can lead to significant complications. Named after the surgeon who successfully removed a vermiform appendix from a hernia sac, Amyand's hernia is a rare finding. Similarly, an inguinal bladder hernia (IBH) is a rare condition where part of the urinary bladder protrudes into the inguinal canal. We present a unique case of a 62-year-old male who presented to the emergency department with a one-day history of lower abdominal pain, exacerbated by physical exertion. The absence of associated symptoms like nausea, vomiting, fever, or urinary symptoms made his condition challenging to diagnose clinically. However, computed tomography (CT) scans of the abdomen and pelvis confirmed the diagnosis of concurrent Amyand's hernia and IBH. The definitive treatment for symptomatic and painful inguinal hernias involves surgery, either open or laparoscopic hernia repair, while asymptomatic, lower-risk inguinal hernias may be observed before intervention is warranted. This report underscores the challenge of balancing the benefits of standardizing diagnostic protocols, particularly preoperative diagnosis and management guidelines for rare variants of inguinal hernias, with the associated costs. In this case, the absence of typical urinary symptoms commonly seen in IBH further complicated the diagnostic process, exemplifying the challenge of identifying such rare anomalies. While standardized screening could help prevent serious and potentially fatal complications, it also poses a strain on medical resources and may lead to unnecessary emotional and physical stress for patients when screening for rare variants of inguinal hernias.

Amyand's Hernia diagnosed preoperatively via a CT scan: A case report

Amyand's hernia is a rare type of inguinal hernia characterized by the presence of the vermiform appendix within the hernia sac. It was named after Claudius Amyand who performed the world's first successful appendectomy on an 11-year-old boy with a right inguinal hernia in 1735 and discovered a herniated appendix during surgery. This condition warrants urgent surgical treatment, with the type of surgical intervention depending on the appendix's condition. However, the nonspecific clinical presentation often complicates the preoperative diagnosis, emphasizing the critical role of imaging in surgical planning. Herein, we present the case of a 74-year-old male who presented with fever, inguinal swelling, and discomfort. Clinical suspicion of inguinal and scrotal inflammation prompted us to perform a prompt CT scan. This radiological evaluation led to a preoperative diagnosis of a Type 3 Amyand's hernia. This case highlights the significance of CT scans in the accurate and timely diagnosis of Amyand's hernia. Distinguishing between various types of Amyand's hernia is pivotal as it profoundly influences surgical decision-making and postoperative outcomes. By sharing this case, we contribute to current knowledge about Amyand's hernia, increase clinical awareness of the condition, and emphasize the crucial role of imaging in its management.

Amyand's hernia: a case of right inguinoscrotal hernia with appendiceal content

Introduction

Amyand's hernia, a rare condition where the appendix becomes lodged in the inguinal canal, poses diagnostic challenges due to its varied clinical presentations and lack of distinctive radiological features. This case underscores the importance of early detection and comprehensive diagnostic evaluation.

Case Presentation

A 30-year-old male presented with a 2-year history of right inguinoscrotal swelling, culminating in agonizing symptoms and irreducible masses over the inguinoscrotal area. Despite the absence of significant medical history, diagnostic imaging confirmed a complete right inguinoscrotal hernia and bilateral hydrocele with internal echoes.

Clinical Discussion

The case illustrates the difficulties in preoperative diagnosis of Amyand's hernia, emphasizing the reliance on imaging modalities and clinical assessment. Successful surgical intervention involving appendectomy and hernioplasty highlights the necessity for prompt diagnosis and management.

Conclusion

This case exemplifies the challenges and complexities associated with Amyand's hernia, emphasizing the importance of early recognition and comprehensive surgical planning. Moving forward, increased clinical vigilance and awareness are essential to ensure optimal patient outcomes in cases of inguinoscrotal pathology.

Amyand's Hernia: An Uncommon Encounter of an Appendiceal Presence in an Inguinal Hernia

Amyand's hernia is a rare variant of inguinal hernia characterized by the presence of the vermiform appendix within the hernia sac. It represents a unique diagnostic and management challenge for surgeons due to its low incidence and varied clinical presentations. Here, we present a case of a 45-year-old man with a one-year history of right inguinoscrotal swelling, diagnosed as a right indirect inguinal hernia. Preoperative imaging revealed the presence of omentum within the hernia sac. Intraoperatively, both the omentum and the vermiform appendix were found within the sac without evidence of inflammation. The patient underwent successful Lichtenstein meshplasty without appendicectomy. This case highlights the importance of considering Amyand's hernia in the differential diagnosis of inguinal hernias and the significance of intraoperative findings in guiding surgical management. Further studies and case reports are needed to enhance our understanding of this rare clinical entity and optimize patient outcomes.

Emergency totally laparoscopic surgery for appendicitis in right Amyand's hernia associated to symptomatic left inguinal hernia: A case report

INTRODUCTION AND IMPORTANCE

Amyand's hernia is a rare type of inguinal hernia which contains vermiform appendix in the inguinal sac, seldom complicated by acute appendicitis. It is usually repaired by open inguinal approach, but laparoscopic technique has been increasingly described in literature; nevertheless, standard of care is far from being defined. Here we report the case of Amyand's hernia complicated by acute appendicitis and simultaneous symptomatic left inguinal hernia, both repaired by laparoscopic technique.

CASE PRESENTATION

A 85-years-old man presented with acute appendicitis in Amyand's hernia and simultaneous incarcerated left inguinal hernia.

CLINICAL DISCUSSION

After complete preoperative work-up, the patient underwent laparoscopic appendectomy and laparoscopic bilateral hernia repair with mesh.

CONCLUSION

Laparoscopic approach may be safe and feasible for Amyand's hernia treatment in emergency setting when performed by expert hands, with minimized risk of surgical site infection (SSI), quick recovery and reduced hospital stay. Laparoscopic hernia repair with mesh can be a reasonable approach in selected cases of bilateral or recurrent hernia, and concomitant intrabdominal inflammation, especially when contamination is scarse and limited to a restricted area.

Perforated Amyand hernia with an adenocarcinoma tumour presenting as a groin abscess

An Amyand hernia is an incarcerated inguinal hernia containing the appendix with or without appendicitis. This is a rare form of inguinal hernia, making up approximately 0.4%-1% of all cases. As with any hernia, this may become strangulated at any time, leading to the loss of blood supply and further development of gangrene and complications. Clinically, this can present in a manner indistinguishable from other types of inguinal hernias. In addition, the appendix can be affected by its own set of pathological processes, such as infection, inflammation, and malignancy. Not uncommonly both hernial and appendiceal complications coexist. The clinical diagnosis of an Amyand hernia remains challenging due to its low incidence and indistinct clinical presentation. At present, surgery is usually diagnostic and therapeutic. However, there is a growing number of recent reports showing the invaluable role of imaging on the diagnosis of Amyand hernias and associated complications. The correct and timely recognition of their imaging features including complications can optimize and expedite patient care by guiding diagnosis, treatment, and prognosis. Here, we report for the first time the radiological and pathological findings of a patient with a unique complicated Amyand hernia, which posed a diagnostic challenge for the clinical and radiological teams.

Amyand's Hernia: A Rare Case Study of Perforated Appendicitis in an Inguinal Hernia

Amyand's hernia is defined as the presence of an appendix contained within an inguinal hernia. An inguinal hernia is the protrusion of a small or large bowel through a peritoneal defect of the groin. In rare cases, the appendix can become incarcerated or strangulated within the hernia, cutting off the blood supply to the organ. If incarcerated, the appendix is at risk for strangulation, which can lead to rupture and cause worsening of symptoms and/or collapse. We report a case of a 76-year-old male with a history of inguinal hernia repair 30 years prior, who presented with 30 days of intermittent right lower quadrant pain and unintentional weight loss. He required emergent treatment and management. This case underscores the challenge of diagnosing concurrent inguinal hernia and appendicitis and places an emphasis on timely intervention. Treatment options vary based on the appendix's apparent condition within the hernia sac. Despite the complications, including additional drainage site and enterocutaneous fistula, the patient was discharged in stable condition. This case contributes insights into managing complex inguinal pathologies, particularly in the geriatric population.

Amyand's Hernia With Sliding Component: A Case Report

Amyand's hernia (AH) occurs when the appendix becomes part of an inguinal hernia. Amyand's hernias are typically discovered incidentally during surgery due to their variable clinical manifestations and features, such as caecum and appendix forming the sliding component in the present case. Claudius Amyand operated it for the first time in 1735. Due to the simple presentations that these patients typically exhibit, the diagnosis is extremely challenging. The choice between surgical modalities is influenced by the numerous, logically accepted advantages and disadvantages of management modalities, which are subject to debate. That being said, we believe that, in the absence of sepsis or inflammation, open repair using mesh - as long as a clean operating room and competent surgical skill are available - should be the gold standard approach.

Amyand's Hernia: Incarcerated Appendicitis in a Recurrent Inguinal Hernia in an Adult

Inguinal hernias are among the most common cases presented to a surgeon. In spite of extensive research and clinical experience over centuries, inguinal hernias still pose anatomical challenges for operating surgeons, especially with a propensity for recurrence. One such complicated entity is the Amyand's hernia - defined as an inguinal hernia contained within the hernial sac - the vermiform appendix - as the herniated content. It is a rare clinical presentation and carries with it certain complexities with regard to operative decisions and clinical management. We present a case of a 71-year-old male presenting with a recurrent inguinal hernia, with an incarcerated, inflamed appendix as the content; managed surgically with appendicectomy and herniorraphy, without the use of a prosthetic mesh.

Controversies Regarding Mesh Utilisation and the Attitude towards the Appendix in Amyand's Hernia-A Systematic Review

Inguinal hernia containing the vermiform appendix is a rare entity. It is more common in children than in adults. It can be discovered incidentally during the surgical intervention performed for the cure of the inguinal hernia or when the appendix shows inflammatory changes, a situation that can lead to diagnostic confusion with a number of other diseases. Imaging can guide the diagnosis, which often comes as an intraoperative surprise. The therapeutic approach is controversial both in terms of whether or not to perform an appendectomy in the case of an appendix without inflammatory changes and especially in terms of using a mesh during the hernia repair process. Since the pathology is not very frequent, there are no standardized stages in terms of surgical ethics that can guarantee good surgical practice. The study aimed to carry out a review of the specialized literature to obtain some conclusions or trends regarding the management of this pathology. The low frequency of this type of hernia did not allow the consultation of large-scale studies or extensive reviews focusing on case reports or case series communications. The obtained results were statistically analyzed and integrated in relation to the surgical attitude depending on the particularities of the condition.

Amyand's hernia with a perforated appendix and an enterocutaneous fistula: A case report

INTRODUCTION

Amyand's hernia is a rare finding accounting for less than 1 % of inguinal hernias. The appendix with its pathology within the hernia sac may become isolated from the gastrointestinal tract, which can cause further confusion in clinical diagnosis. Awareness of the possibility of such appendiceal isolation could aid in clinical diagnosis. We report a rare case of Amyand's hernia complicated with a perforated appendix and an enterocutaneous fistula.

PRESENTATION OF CASE

A 64-year-old gentleman with diabetes mellitus type II and hypertension presented with a right inguinal swelling associated with a malodorous discharge without features of intestinal obstruction. Ultrasonography revealed a right inguinal hernia with features of partial strangulation. He underwent a right inguinal exploration with subsequent debridement, appendicectomy and a herniorraphy. The patient had complete recovery and histopathology revealed acute appendicitis.

DISCUSSION

Amyand's hernia is rare and difficult to diagnose pre-operatively. Appendicitis in Amyand's hernia is rarer still and may be caused by intraluminal or extraluminal obstruction. Clinical presentation is variable and ultrasonography and computed tomography (CT) scan aid in diagnosis. Appendicectomy is regarded as unnecessary when the appendix is normal. Synthetic mesh should be avoided when the appendix is inflamed or perforated.

CONCLUSION

Amyand's hernia is rare and difficult to diagnose. Ultrasonography and CT scan are valuable tools for pre-operative diagnosis. Isolation of the appendix with its pathology within the hernia sac can add to the confusion in clinical diagnosis. Management of Amyand's hernia should be tailored according to the pathology encountered and treatment should not be delayed.

Challenges in strategies for Amyand hernia in children: literature review with clinical illustrations

Introduction

Amyand hernia (AH) is a rare disease, so there are no standard strategies and there are many different aspects at each stage of its management. Based on our own experience, we encountered these differences even in a small number of cases and therefore sought to review the literature to highlight the diversity of approaches to this pathology. This review of the literature was not intended to describe the statistical findings found in the clinical case series, but rather to highlight the clinical and surgical difficulties of AH in children. Nevertheless, we conducted an introductory statistical study based on data from PubMed and Google Scholar to understand the global prevalence of AH.

Materials and methods

The search for the key terms Amyand hernia, Amyand’s hernia, and “children” between 2003 and 2023 resulted in 52 PubMed and 548 Google Scholar articles.

Results

After the exclusion of irrelevant studies, 101 articles were found. A total of 83 case reports describing 182 pediatric patients were used to understand the demographic distribution of this pathology. Given the impossibility of further comprehensive statistical analysis (due to heterogeneous data), a narrative design was used to describe the remaining aspects of AH management. Finally, three clinical cases demonstrated the mentioned aspects.

Discussion

As a result of the search, conclusions were drawn about the main difficulties in the management of AH in children, which were discussed.

Amyand hernia as a rare cause of abdominal pain: A case report and literature review

Key Clinical Message

Amyand's hernia is an uncommon kind of inguinal hernia in which the appendix becomes entrapped within the hernia sac. In patients with an inflamed or perforated appendix, mesh repair is not recommended for hernia repair.

Abstract

Amyand's hernia is an uncommon kind of inguinal hernia in which the appendix becomes entrapped within the hernia sac. We report a 48-year-old man with a right groin protrusion and abdominal pain. In the abdominopelvic ultrasound, an appendix with a diameter of 9 mm was reported in the right inguinal canal. The patient was diagnosed with Amyand hernia.

Rare Hernias as Surgical Emergencies: A Case Series of Five Cases

Hernia is one of the most common clinically diagnosed cases seen in day-to-day practice. But some of them might pose a challenge in diagnosing the condition and, thus, their further management. Some types of hernias are rare and mimic the common presentation of the acute abdomen, thus requiring extra caution to keep hernias as a differential diagnosis in the acute abdomen. In this series, we report five cases of rare hernias presented to a tertiary care center in northern India over the course of one year. Two cases of paraduodenal hernias (PHs), a right and left, respectively, a male femoral hernia, an Amayand hernia, and an obturator hernia presented as acute abdomen in the emergency department, with challenges in their diagnosis, intraoperative findings, and their outcomes. Computed tomography is a useful diagnostic tool for arriving at the diagnosis pre-operatively in these situations.

Fishbone-Induced Appendicular Perforation: A Rare Case Report of Amyand's Hernia

Amyand's hernia is a rare type of hernia where the appendix is found to be the content of the inguinal hernial sac. It is most often diagnosed intraoperatively wherein the appendix may be found healthy, incarcerated, inflamed, or perforated. Claudius Amyand performed a successful appendectomy on a patient with an appendix noted in the inguinal canal and this condition was hence named after him. The incidence of Amyand's hernia is rare in inguinal hernia patients. There are no defined guidelines for the management of Amyand's hernia but adequate resuscitation followed by immediate appendectomy is widely followed. Here is a case report of a 60-year-old male presenting to the Emergency Department with an irreducible right-side inguinal hernia with features of small bowel obstruction. On exploration, Amyand's hernia was identified with appendicular tip perforation due to an impacted fishbone with pyoperitoneum. Appendectomy was done through midline laparotomy with impacted fishbone removal from the hernial sac with tissue repair of the hernia. There are as such no reported cases of fishbone-induced appendicular perforation in an Amyand's hernia in the available literature. After the exploration, we found the management of the case challenging regarding the closure of the hernia.

Appendiceal Abscess Within a Giant Amyand’s Hernia: A Case Report

Amyand's hernia is a rare clinical entity, defined as an inguinal hernia containing the appendix. Giant inguinoscrotal hernia is also a rare clinical finding that presents major operative dilemmas due to the loss of abdominal domain. Here, we report a case of a 57-year-old male who presented with a giant irreducible right inguinoscrotal hernia and obstructive symptoms. The patient underwent an emergency open right inguinal hernia repair, where an Amyand's hernia was identified. The hernia contained an inflamed appendix and associated abscess, caecum, terminal ileum, and descending colon. Using the giant sac to isolate the contamination, an appendicectomy was performed, the hernial contents reduced and the hernia repair reinforced with partially absorbable mesh. The patient recovered post-operatively and was discharged home with no recurrence on four-week follow-up. This case provides learning points on decision-making and surgical management of a giant inguinoscrotal hernia containing an appendiceal abscess, also known as Amyand's.

Vermiform Appendix within Post-Laparoscopic Incisional Hernia: A Unique Case Report and Literature Review

Background: Appendicitis within incisional hernia is an extraordinarily rare postoperative complication with an incidence range from 0.08 to 1%. From the 14 cases that we found in the English literature, only three present appendixes vermiform in incisional hernia followed by laparoscopic surgery. Only two cases are treated minimally invasively by the laparoscopic approach. Case presentation: We introduce a 65-year-old man who had a laparoscopic sigmoid colon resection and had a lump found at the 12 mm trocar site in the right iliac area in the late postoperative phase. There were no complaints from the patient. A vermiform appendix was unexpectedly discovered in the sac of that incisional hernia during control CT scans performed by chemotherapists. Laparoscopic hernia repair without appendectomy was performed. Postoperative outcomes were excellent. Conclusions: Because of low incidence and a lack of distinctive clinical presentation of appendicitis within incisional hernia, there is a risk of delayed perioperative diagnosis and treatment. A CT scan might play an important role in verifying the diagnosis early. For better postoperative outcomes, if possible, laparoscopic surgery should be chosen.

Incarcerated left-sided Amyand's hernia and synchronous ipsilateral femoral hernia: first case report

BACKGROUND

The finding of a vermiform appendix within the peritoneal sac of an inguinal hernia is called Amyand's hernia. The reported incidence of Amyand's hernia and femoral hernia is 1% and 3.8%, respectively. To our knowledge, no cases have been reported in the literature that associate these two entities. We present the first case of incarcerated left-sided Amyand's hernia and synchronous ipsilateral femoral hernia found during emergency surgery.

CASE PRESENTATION

A 72-year-old woman was admitted to the Emergency Department for a complicated left inguinal hernia. An inguinotomy was performed that detected a large direct hernial sac and a synchronous femoral hernia. The opening of the inguinal hernia showed the presence of the cecum and the appendix, both without signs of inflammation. The femoral space was evaluated transinguinally, identifying the larger omentum that had slipped into the femoral canal. The primary closure of the posterior wall defect was performed with the McVay technique due to its large size, and then the hernioplasty was completed with a polypropylene mesh. No postoperative complications were reported.

CONCLUSIONS

In the context of an incarcerated Amyand's hernia, the decision to perform an appendectomy in addition to hernia repair with or without mesh will depend on intraoperative findings.

Amyand's hernia combined with contralateral recurrent inguinal hernia: A case report

INTRODUCTION

Amyand's hernia (AH)-where the appendix becomes incarcerated within the inguinal hernia (IH) sac-is rare, particularly if detected and operated concurrent with a contralateral recurrent IH.

PRESENTATION OF CASE

A 65-year-old man presented with symptomatic bilateral IH; the left IH was recurrent. Abdominopelvic computed tomography (CT) revealed a right IH with appendiceal herniation and left recurrent IH with omental fat. Using the prolene hernia system (PHS) mesh, the left recurrent IH underwent operation, followed by the right AH. The patient was in a good state with no recurrence 16 months postsurgery.

DISCUSSION

If AH is accidentally encountered during surgery, the procedure should differ depending on the inflammatory state of the appendix. Simultaneously operating AH and contralateral recurrent IH is complicated; it is necessary to preoperatively decide which side to operate on first and whether to use an anterior or laparoscopic posterior surgical approach. If the planned operation is unattainable, alternative surgery should be considered. Fortunately, herein CT was performed prior to surgery, and the surgical plan was properly established.

CONCLUSION

Prior to simultaneous AH and contralateral recurrent IH surgery, the surgical plan should be established. If the planned surgical technique for recurrent hernia repair is not feasible, an alternative should be performed. In AH repair, different surgical methods are required depending on the presence and severity of inflammation of the appendix.

Amyand hernia; a case report on serendiptous intra-operative diagnosis

Introduction and Importance

Amyand hernia is an accidental finding that occurs in 0.19–1.7% of patients with inguinal hernia, with children being more commonly affected than adults. However, the management depends on the guidelines given by Losanoff and Basson.

Case Presentation

A 62-year-old male presented with complaints of progressive swelling in the right inguinal region without any clinical spectrum of bowel obstruction or strangulation. Examination revealed a right-sided indirect inguinal hernia with positive Ziemann technique. Open hernioplasty revealed an appendix within a hernia sac and was found to be adhered to the surrounding structure with a fibrotic band. According to the Losanoff and Basson protocol, the patient had an appendectomy and an open mesh repair with polypropylene mesh without any post-operative complications.

Clinical Discussion

Amyand hernia are often predominantly present in children, with a rare presence in the elderly. Pre-operative clinical diagnosis remains a challenge, and the management depends upon the Losanoff and Basson protocol. Appendectomy of the normal appendix within the hernia sac is often recommended to prevent the sequelae (appendicitis, rupture) following manipulation during hernioplasty.

Conclusion

Amyand's hernia is a rare clinical entity and difficult to diagnose due to its uncomplicated presentation. Nevertheless, the progress of appendix inflammation, the possibility of abdominal sepsis, and co-morbidities should all be taken into consideration when deciding how to manage individual patients.

•

Amyand's hernia is a rare clinical entity characterized by the presence of a vermiform appendix (normal or inflamed or perforated) within an inguinal hernia sac.

•

Preoperative diagnosis of this clinical condition is uncommon and remains primarily an incidental intra-operative finding.

•

Management with appendectomy is a must to prevent the deleterious sequelae of acute appendicitis and hernioplasty with or without mesh repair depending upon the status of the appendix.

Laparoscopic simultaneous inguinal hernia repair and appendectomy in children: A multicenter study

BACKGROUND

Inguinal hernias (IHs) are sometimes encountered incidentally in children during laparoscopic appendectomy. This study aims to evaluate the efficacy and outcomes of laparoscopic simultaneous inguinal hernia repair and appendectomy in children.

METHODS

A multicentric study was performed in patients with AA and concurrent IH who received laparoscopic simultaneous inguinal hernia repair and appendectomy (study group), compared with patients who underwent two-stage laparoscopic procedures (control group) between September 2012 and January 2020. Intraoperative data, postoperative complications, and clinical outcomes were prospectively collected and retrospectively analyzed.

RESULTS

189 patients with AA and concurrent IH (117 children in the study group, and 72 children in the control group) were enrolled. No significant differences in preoperative characteristics were identified between the two groups. Patients in the study group had a shorter total operative time and hospital stay than those in the control group (43.2 ± 8.1 vs 53.9 ± 7.3 min, p < 0.001; 1.5 ± 0.8 vs 2.2 ± 0.9 days, p = 0.023). The study group incurred lower costs than the control group (9198.7 ± 587.6 vs 14,392.5 ± 628.6 RMB, p < 0.001). During follow-up (range 1.5-6.0 years), three children in the study group and two children in the control group experienced wound infection. One child in the study group had recurrent IH.

CONCLUSIONS

Laparoscopic simultaneous procedures do not increase the incidence of wound infection or recurrent IH. Moreover, they avoid repeat anesthesia and hospitalization. Therefore, this approach is safe, feasible and cost-effective for children with AA and concurrent IH.

Emergency imaging of a rare cause of inguinal swelling: Amyand's hernia with perforated appendicitis and abscess-cutaneous fistula - a case report and review of the literature

Inguinal hernias containing the appendix are rare, but even more exceptional is the occurrence of complicated appendicitis within the hernial sac with a cutaneous fistula. We report the case of a man in his 50s presenting to the emergency department with a right-sided erythematous and painful inguinal swelling secreting seropurulent material. A perforated appendix within an inguinal hernia complicated by an appendico-cutaneous fistula was diagnosed.

Inguinal Hernia Containing an Inflamed Appendix: A Case of Amyand Hernia

Inguinal hernia is a prevalent surgical condition worldwide. The hernia sac typically contains the omentum and small intestine. However, it has been reported that some other organs might be seen, including the ovary, fallopian tube, bladder, and colon. We report the case of a 23-year-old man who presented to our emergency department with the complaint of scrotal pain for the last six days. The pain was mainly in the right side. There was no history of preceding trauma, and the pain developed gradually. He described the pain as having a sharp nature and was constant. He reported having a low-grade fever that resolved with the use of over-the-counter analgesics. There was no change in the urine or bowel habits. No penile discharge was reported. On examination, the patient had a low-grade fever and tachycardia. The patient appeared in pain and was not cooperative to have a complete genitalia examination. However, there was a positive cough impulse in the right inguinal region. The laboratory findings suggested the presence of inflammatory or infectious processes with elevated leukocytes, C-reactive protein, and erythrocyte sedimentation rate. The patient was prepared for emergency laparotomy for reduction of the hernia and resection of the appendix. During exploration, the appendix was reduced from the hernia sac. The appendix appeared edematous, with marked erythema representing acute appendicitis. The appendix was resected and the hernia sac was closed. The presence of an appendix in the inguinal hernia sac is very rare. The preoperative diagnosis of Amyand hernia, the inguinal hernia containing the appendix, can be difficult based on the clinical presentation. Early diagnosis is crucial to avoid the potential complications of Amyand hernia, including perforation and abscess formation. Imaging studies can establish the diagnosis of Amyand hernia with high accuracy and confidence.

Amyand's hernia- outcome of nylon darn repairs after complicated appendix surgeries in a district hospital: case series

INTRODUCTION

Complicated appendix is a least expected sac content of inguinal hernias that always require appendix surgery and hernia repair. The current recommendations for posterior wall repairs however, continue to attract conflicting views as to which modality gives the best outcome in infected surgical wounds. New posterior wall repair methods with properties to withstand surgical site infections, minimise hernia recurrence, affordable and easy skill to acquire with a potential to be widely adopted are continuosly sort.

AIM

To determine the surgical outcomes of complicated Amyand Hernias repaired using the open tissue base Nylon Darn posterior wall re-enforcement method.

METHOD

A retrospective review of medical records of patients who had surgery for emergency inguinal hernia with intra-operative confirmation of complicated appendix in the hernia sac from January 2015 to December 2020 at the Margaret Marquart Catholic Hospital, Kpando were included. Data on age, sex, clinical presentation, surgical procedure, intra-operative findings, post operative complications were captured and presented as descriptive statistics.

RESULTS

Twelve out of 286(4.6%) repairs were complicated Amyand Hernias in patients aged 6weeks to 76-years{median age 54.5-years}. Most of them were adults, long-standing hernias. All diagnosis were made on-table. Surgical site infections was the most frequent complication in types III and IV AHs which resolved with antibiotic treatment.

CONCLUSION

The incidence of complicated AHs is higher and should be anticipated in surgeries for long-standing complicated inguinal hernias. Even though complications were significantly associated with longer hospital stay, no second procedure or mortality was recorded.

Laparoscopic repair of bilateral inguinal hernias each containing sigmoid colon in a premature infant

Inguinal hernias are rare in the general population but are more frequently seen in premature infants. Risk factors include male gender, small for gestational age, low birth weight and respiratory distress. Infant inguinal hernias most frequently contain small bowel. Other contents can include the appendix and cecum, and rarely, the sigmoid colon. Sigmoid colon as content of inguinal hernia in children has only been reported twice in literature, and in both cases it was unilateral. We present the first reported case of bilateral inguinal hernias containing the sigmoid colon in a premature boy, who additionally had the appendix and the cecum in the right hernia. This is also the first reported laparoscopic repair of such a hernia.

Appendiceal Carcinoid Tumor Contained in a Large Inguinal Hernia: A Case Report

We report the first case of a clinically diagnosed incidental appendiceal carcinoid tumor contained in an incarcerated inguinal hernia without inflammation of the appendix. A 67-year-old white man underwent elective open repair of an incarcerated right inguinal hernia containing small bowel, cecum, appendix, and ascending colon. He was found to have a grossly abnormal mass at the tip of his appendix. Appendectomy was performed, and histopathologic analysis confirmed the presence and adequate resection of a neuroendocrine tumor. It is important for general surgeons to be aware that unusual presentations of appendiceal tumors may not be associated with appendiceal inflammation or related symptoms.

Amyand Hernia With Acute Appendicitis: A Rare Type of Hernia

A hernia is an abnormal protrusion of an organ or tissue from its containing cavity. Inguinal hernia is the most common type of abdominal hernias. The presence of the appendix within the inguinal hernial sac is a rare occurrence. We present the case of a 41-year-old man, with no previous surgical history, who presented to the emergency department with a right-sided painful groin swelling. The swelling was associated with nausea, vomiting, anorexia, and fever. Initial laboratory investigation revealed leukocytosis and elevated C-reactive protein and erythrocyte sedimentation rate. A computed tomography (CT) scan demonstrated the presence of an inflamed appendix with an inguinal hernia. The patient underwent laparoscopic repair of the hernia with appendectomy. The patient tolerated the procedure without any complications. Amyand hernia with acute appendicitis is a very rare surgical condition. Clinicians should have a high index of suspicion for Amyand hernia with appendicitis when they encounter a patient with groin mass with laboratory markers indicating an inflammatory process.

Amyand's hernia: a 10-year experience with 6 cases

PURPOSE

Amyand's hernia is a rare hernia defined as an inguinal hernia that contains the appendix within the hernia sac. Current treatment of Amyand's hernia remains controversial. Our study retrospectively reviewed 6 cases of Amyand's hernia, aiming to provide a reference for the surgical treatment of Amyand's hernia.

METHODS

Six patients diagnosed with Amyand's hernia from September 2010 to May 2020 were retrospectively enrolled in our study. We summarized clinical data of six patients including the chief complaint, physical examinations, laboratory examinations, imaging examinations, surgical methods, and postoperative treatments and outcomes.

RESULTS

The diagnosis of six cases with Amyand's hernia was made during surgery. Two patients had normal appendixes whereas the remaining four patients had appendicitis. Two patients with normal appendix received tension-free mesh repair through the inguinal incision. Among those with inflamed or perforated appendixes, two received mesh repair and the other two did not. The discharge time after surgery of six patients was 9.8 ± 6.1 days. One patient suffered from a wound infection. No additional postoperative complications were detected.

CONCLUSIONS

Computed tomography and ultrasonography are helpful but limited in the definite diagnosis of Amyand's hernia. The presence of a normal appendix does not require to be resected, but appendicectomy is necessary if the appendix is inflamed. The treatment of Amyand's hernia should be tailored based on the patient's condition and the type of Amyand's hernia.

Sliding Amyand's hernia: a case report and review of literature

First operated by Claudius Amyand in 1735. Amyand's hernia is a rare presentation and accounts for only 1% of all inguinal hernias. Amyand's hernia is described when the appendix is trapped within an inguinal hernia. In most cases, Amyand's hernia is an incidental finding intra-operatively due to variable clinical manifestations, and features. Amyand's hernia has variable theories explaining its pathophysiology besides having multiple proposed surgical approaches either via laparoscopic or open repair and with the latter being in a debate of pro and against mesh repair. We present a case of a sliding Amyand's hernia in which the vermiform appendix and part of the cecum were adherents to the wall of a right inguinal hernial sac. Amyand's hernia is a rare form of inguinal hernias and its presentation is widely variable. However, in most cases, it is non-complicated and is found as an incidental intraoperative finding. Many studies debate among different diagnostic and management approaches to serve a better outcome with fewer operative complications.

Appendicitis in an incisional hernia sac following renal transplantation: A case report and brief review of the literature

Acute appendicitis is a surgical emergency. However, the presence of vermiform appendix in a hernial sac is rare. It is even rarer to find inflamed appendix in an hernial sac. The most common site is right groin hernia (Inguinal > Femoral). There is low incidence of an incisional hernia following renal transplantation, as compared to patients with laparotomy. Appendicitis in hernial sac masquerades clinical presentation of an incarcerated hernia. Computed tomography plays a pivotal role in early diagnosis, demonstrating a dilated appendix with wall thickening and peri-appendiceal fat stranding. Patients are managed with appendectomy. The management of appendiceal hernias without inflammation remains controversial, with few reported cases managed with hernia sac repair or appendectomy. In this report were described a case of appendicitis in an incisional hernia following renal transplantation which was managed with appendectomy.

Incidental discovery of Amyand's hernia in an adult female: A case report

Introduction and importance

Amyand's hernia is a rare type of inguinal hernia with an incidence of about 0.1% of all inguinal hernias with most in occurring in childhood. It is characterized by the presence of the vermiform appendix within the hernia sac.

Case presentation

We report the case of 40-year-old female who underwent inguino-labial hernia repair with an incidental finding of a normal appendix within the sac; this was not predicted by the pre-operative ultrasound scan.

Clinical discussion

We recommend that a detailed ultrasound scan be done for all patients with an inguinal hernia to help to manage the patient timeously and safely.

Conclusion

We present a rare condition in a 40-year-old female with a right inguinal hernia, an Amyand's hernia.

•

We report a case of Amyand's hernia in a 40-year-old female who underwent inguinal hernia repair.

•

A normal appendix was found in the sac and reduced without appendicectomy. Hernia repair without mesh was then performed.

•

Ultrasound scan is an excellent technique to evaluate the inguinal region but remains operator dependent.

Amyand's hernia complicated with appendicitis: an interval approach with transabdominal laparoscopic appendectomy and laparoscopic hernioplasty-a case report

Amyand's hernia is a rare classification of inguinal hernia where the vermiform appendix is located within the hernial sac. This case report discusses a patient presenting with abdominal and groin pain shown to be an Amyand's hernia complicated by acute appendicitis on computed tomography. The patient was treated with a two-stage approach, involving transabdominal laparoscopic appendectomy and elective laparoscopic hernioplasty after recovery. As some controversy exists regarding the timing of appendectomy and hernioplasty, we examine the benefits of the interval approach in the reduction of postoperative infection risk compared with a concurrent approach in patients presenting with Amyand's hernia complicated by appendiceal inflammation.

An unusual reason for an inguinal swelling: De Garengeot's hernia

We present the case of a 71-year-old female with an inguinal swelling. Intra-abdominally the appendix was found in a femoral hernia sac (De Garengeot’s hernia). A laparoscopic transabdominal preperitoneal hernia repair procedure was performed with uneventful post-operative course.

Clinical presentation of this type of hernia is unspecific and often not to be distinguished from a common incarcerated hernia. Computed tomography can be helpful in obtaining a diagnosis, although the definite diagnosis is mostly found intraoperatively. As surgical options are numerous, there is no consensus on the most suitable one. A laparoscopic approach incorporates the benefit of a total abdominal overview and the possibility of standard procedures. If the appendix appears normal, the use of synthetic mesh is considered safe and an incidental appendectomy is not necessarily required.

Revisiting Amyand's Hernia: A 20-Year Systematic Review

PURPOSE

Protrusion of the appendix within an inguinal hernia is termed an Amyand's hernia. A systematic review of case reports and case series of Amyand's hernia was performed, with emphasis on surgical decision-making.

METHODS

The English literature (2000-2019) was reviewed, using PubMed and Embase, combining the terms "hernia", "inguinal", "appendix", "appendicitis" and "Amyand". Overall, 231 studies were included, describing 442 patients.

RESULTS

Mean age of patients was 34 ± 32 years (adults 57.5%, children 42.5%). 91% were males, while a left-sided Amyand's hernia was observed in 9.5%. Of 156 elective hernia repairs, 38.5% underwent appendectomy and 61.5% simple reduction of the appendix. 88% of the adult patients had a mesh repair, without complications. Of 281 acute cases, hernial complications (76%) and acute appendicitis (12%) were the most common preoperative surgical indications. Appendectomy was performed in 79%, more extensive operations in 8% and simple reduction in 13% of cases. A mesh was used in 19% of adult patients following any type of resection and in 81% following reduction of the appendix. Among acute cases, mortality was 1.8% and morbidity 9.2%. Surgical site infections were observed in 3.6%, all of which in patients without mesh implantation.

CONCLUSION

In elective Amyand's hernia cases, appendectomy may be considered in certain patients, provided faecal spillage is avoided, to prevent mesh infection. In cases of appendicitis, prosthetic mesh may be used, if the surgical field is relatively clean, whereas endogenous tissue repairs are preferred in cases of heavy contamination.

Amyand's hernia: presumptive diagnosis by CT and literature review

Amyand's hernia is a rare inguinal hernia containing the appendix presenting mainly in male adults. The clinical presentation is usually without symptoms, however an inflammation can occur leading to strangulation, necrosis or rupture of the appendix. Differential diagnosis may be difficult including orchitis, testicular torsion, inflammation of the ovaries and bowel inflammation.

We present a case of a 61 years old, male patient who was presented with persistent right abdominal pain. There was no medical history of previous hospitalization or surgery of the abdomen. Laboratory tests and radiological investigation with plain radiographs and ultrasound were not clear. A CT scan with contrast imaging was performed to reveal the diagnosis.

Amyand's hernia is difficult to be revealed and a high index of suspicion is needed in order to promptly diagnose the hernia and proceed to the appropriate treatment. CT scan is critical contributing to the accurate depiction and to the classification of the hernia.

Not only appendicitis: rare appendix disorders manifesting as surgical emergencies in children

Acute appendicitis is the most common cause of acute abdominal pathology in children. However, other rare non-inflammatory non-neoplastic disorders involving the appendix may manifest as surgical emergencies. This study aimed to describe these atypical entities and present representative cases. The database of a tertiary children's medical center was reviewed for all the patients aged 0-18 years who underwent urgent appendectomy between June 2014 and December 2019, for rare disorders of the appendix unrelated to inflammatory or neoplastic processes. Of 1367 patients who underwent appendectomy, 1345 were operated urgently or emergently. Of these, six, all males, mean age 32.6 months (range 0.7-76), underwent appendectomy for rare surgical complications that involved the appendix. These included torsion of the appendix (2), a strangulated internal hernia through an appendicular ring (1) or through a mesoappendix gap (1), an incarcerated appendix in an acute hernia sac (1), and appendiceal intussusception (1). In all cases, the role of the appendix in the pathologic process was unexpected and came as a surprise to the surgeon. During a median follow-up of 4.2 months (range 1-8 months), one patient underwent relaparotomy for small bowel obstruction 4 weeks after the original procedure.Conclusion: The appendix in children can be the source of rare pathological disorders that present as surgical emergencies. Familiarity with these entities may aid in achieving accurate preoperative diagnosis and contribute to surgical team orientation on exploratory laparotomy. However, correct diagnosis is often only established during timely surgical intervention.

Gangrenous appendicitis in Amyand's hernia: Surgical approach under local anesthesia. Case report and review of the literature

INTRODUCTION AND IMPORTANCE

Amyand hernia is a rare disease seen in approximatively 1% of all hernias, complications of it, like acute appendicitis, or perforated appendicitis are even more rare, about 0.1%. Its diagnosis is very difficult in the preoperative period: it is usually an incidental finding.

CASE PRESENTATION

We report an unusual case of perforated gangrenous appendicitis with peri-appendicular abscess occurring in an irreducible Amyand's hernia. An 80-year-old male, with chronic obstructive disease and pulmonary emphysema, atrial fibrillation, acute myocardial infarction, underwent urgent surgery, under local anesthesia, for right incarcerated inguinoscrotal hernia. He was found to have a perforated gangrenous appendicitis with peri-appendicular abscess within a right indirect inguinal hernia sac. Appendicectomy and Bassini's hernia repair were performed under local anesthesia without any complications.

CLINICAL DISCUSSION

The treatment of Amyand's hernia is not standardized. The current generally accepted algorithm for Amyand's hernia is essentially contingent on the appendix's condition within the hernia sac.

CONCLUSION

Appendectomy and primary herniorrhaphy, under local anesthesia, for type 3 of Amyand's hernia, is a safe procedure and easy to perform and, if confirmed by further study, could be part of every surgeon's knowledge.

Implications of the presence of the vermiform appendix inside an inguinal hernia (Amyand's hernia): a systematic review of the literature

PURPOSE

To identify and sum all available evidence pertaining to the management of Amyand's hernia (AH).

METHODS

A systematic search of the MedLine, Scopus, and Google Scholar databases was performed for studies published until January 2020.

RESULTS

In total, 111 studies incorporating 161 patients were identified, 96 (86.4%) being case reports, 11 (9.9%) case series, and 4 (3.7%) retrospective patient cohorts. Mean patient age was 58.5 ± 19.6 years with 136 (83.9%) being males and 25 (16.1%) females. Furthermore, 149 (92.5%) cases were right-sided hernias while 12 (7.5%) cases were left-sided. Overall, 62.3% of patients presented emergently and 77.3% of patients' cohort were eventually diagnosed with incarcerated AH. Preoperative diagnosis of AH was established in 23.1% of patients and was achieved either by ultrasound (25%) or CT scan (75%). Operative findings consisted of normal appendix in 73 (45.4%) cases, uncomplicated appendicitis in 62 (38.5%) patients, and perforated appendix in 26 (16.1%). Regarding patients with appendicitis, mesh placement was reported for 17 (21.2%), herniorrhaphy was performed for 51 (63.7%) while 12 (15.1%) patients did not undergo hernia repair during the initial operation. Mesh utilization rates were significantly higher in patients with a normal appendix. Seven cases involved AH containing appendiceal neoplasms. Thirteen cases (8.6%) of postoperative complications were documented and a single case of postoperative death.

CONCLUSION

AH is a rare type of inguinal hernia usually complicated by appendicitis. Hernia reconstruction should be tailored to each patient individually according to the extent of inguinal canal inflammation.
