Amyand's hernia (AH) is an extremely rare type of inguinal hernia where the vermiform appendix is present within the inguinal hernia sac. This report documents the first known instance of AH in Sudan, highlighting its unprecedented occurrence in this region. A 2-month-old infant presented to the ER with an obstructed right-sided inguinal hernia for 6 h. During surgical repair, an inflamed appendix was found within the hernial sac. The appendix was ligated, excised, herniotomy was performed to repair the hernia, and the appendix was sent for histopathological examination. This case underscores the importance of recognizing rare presentations of common conditions in different geographical and demographic contexts. The co-occurrence of acute appendicitis and AH in infants poses a diagnostic challenge, often only detected incidentally during surgical exploration. By presenting this unique case, we aim to raise awareness about the potential for such rare hernias in pediatric populations. Early recognition and proper management are crucial for ensuring optimal patient outcomes and preventing complications associated with delayed diagnosis or treatment. • First documented case of Amyand's hernia (AH) in Sudan. • AH diagnosed in a 2-month-old infant with an obstructed right-sided inguinal hernia. • Surgical repair revealed an inflamed appendix within the hernial sac. • Case emphasizes the need for early recognition and management of rare hernias in infants. • Raises awareness of AH in pediatric populations in diverse geographic regions [ABSTRACT FROM AUTHOR]

Amyand's hernia with concurrent appendicitis is rare, with a reported incidence of 0.13 % of all inguinal hernias. This condition is challenging to diagnose and manage and no optimal treatment has been established. A 71-year-old man presented with an acutely painful, tender, and irreducible right inguinal hernia. He had a history of a right inguinal hernia for several months and had undergone open left inguinal hernia repair. The patient had no other medical comorbidities. Blood test results were nonspecific, with a C-reactive protein of 90 mg/L. Ultrasound scan suggested a strangulated right inguinal hernia. Laparoscopy revealed an Amyand's hernia with concurrent appendicitis and a pus-filled right inguinal hernia sac. The patient underwent laparoscopic appendicectomy, followed by staged laparoscopic transabdominal preperitoneal right inguinal hernia repair with mesh after eight weeks to reduce mesh infection. Histopathological examination confirmed acute uncomplicated appendicitis without perforation or malignancy. The patient had an unremarkable post-operative recovery. This case highlights the diagnostic challenges associated with Amyand's hernia and concurrent appendicitis. Laparoscopy provides both diagnostic and therapeutic opportunities. In this case, laparoscopic mesh herniorrhaphy was delayed and staged until local hernia sac inflammation resolved following appendicectomy. Surgeons should have an index of suspicion for Amyand's hernia given the heterogeneity of presentations. A case-by-case approach is required to prevent post-operative complications and determine the safe timing of definitive hernia repair when the inguinal hernial sac is inflamed. Further research is required to provide surgeons with evidence-based approaches for this unique condition. • Amyand's hernia and concurrent appendicitis present diagnostic challenges. • Surgeons should consider Amyand's hernia when patients have acute groin lumps. • Laparoscopy can offer both diagnostic and therapeutic benefits. • Hernia repair after appendicectomy should be personalized. • It should consider hernia sac inflammation and mesh infection risk.

Amyand's hernia (AH) is a rare condition in which the vermiform appendix is incarcerated within the inguinal hernia (IH) sac. Although infrequent, it may become inflamed or perforated and can typically be diagnosed either intraoperatively or through radiographic findings. A 77-year-old male presented to the emergency room with constipation, fever, and an irreducible right inguinal bulge accompanied by slight localized discomfort that had persisted for ten days. Clinical examination was unremarkable, while ultrasound revealed a non-ischemic small bowel loop and a right testicular hydrocele, leading to a primary diagnosis of incarcerated IH. The patient was subsequently admitted for surgery, during which AH was confirmed. The appendix was inflamed, enlarged, and perforated, with localized abscess and internal inguinal ring stenosis. Subsequently, the surgical treatment involved appendectomy and hernia repair. According to the appendix condition, four subtypes of AH can be encountered, with type III -perforated appendicitis- being the focus of this report. In this case report, inguinal ring stenosis was the underlying cause of complications besides the unusual presentation features that were also attributed to adhesions that prevented peritoneal involvement. Surgeons should consider AH in the differential diagnosis of inguinal swelling and be familiar with the surgical management approach in the incidental event of AH during surgery. • An uncommon case of a strangulated Amyand's hernia. • Diagnosis of Amyand's hernia is challenging and often confirmed intraoperatively. • In this case, tight internal inguinal ring narrowing and adhesions were the underlying cause of strangulation. • Surgeons should consider Amyand's hernia in differential diagnosis; therefore, it can be familiar intraoperatively.

Amyand's hernia is a rare type of inguinal hernia which involves either a normal or diseased appendix within the hernia sac. We report an extremely rare case of appendiceal neuroma, presenting as an incarcerated Amyand's hernia. A 55-year-old male patient presented in the emergency department due to a persistent right inguinal painful swelling. Clinical examination revealed a 5 cm × 3 cm firm and irreducible right groin mass. A diagnosis of an incarcerated right inguinal hernia was made, and the patient was prepared for surgery. Intraoperatively, a 5 cm × 3 cm firm mass originating from the distal part of the appendix was found in the hernia sac. An appendectomy and a modified Bassini hernia repair were done. The result of the histological examination revealed appendiceal neuroma, and no further surgical intervention was needed. Amyand's hernia encompasses various pathological features, including a normal, inflamed, or perforated appendix, and rarely appendiceal tumors. In the literature, we found about eight cases of malignant appendiceal tumors reported. Most of the cases indicate that the treatment of Amyand's hernia containing appendiceal tumors was an appendectomy alone, while one report with adenocarcinoma required a right hemicolectomy after biopsy result. Notably, there are no documented cases of appendiceal neuromas presenting as inguinal hernias in our search of English literature using Google Scholar and PubMed search engines. Amyand's hernia-containing appendiceal neuroma is an extremely rare entity. It is important to do histopathologic study to differentiate appendiceal neuroma from malignant tumors. In case of Amyand's hernia with appendiceal neuroma, simple appendectomy with hernia repair is adequate treatment. • Amyand's hernia with appendiceal neuroma is extremely rare entity. • Malignant appendiceal tumors should be ruled out histopathologically. • Appendectomy alone with hernia repair is the treatment option for Amyand's hernia containing appendiceal neuroma.

• The Amyand's hernia is a rare disease. • Acute appendicitis in Amyand's hernia is very very rare. • Acute appendicitis diagnosis in Amyand's hernia is very difficult in the preoperative period. • The treatment of Amyand's hernia is not standardized. • Appendectomy and herniorrhaphy under local anesthesia is a safe procedure. 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. 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. 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. 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.

• Amyand's hernia management remains controversial. • Use of mesh or not in Amyand's hernia. • Role of CT scan in diagnosis of Amyand's hernia. • Literature review of Amyand's hernia and classification systems. An Amyand's hernia is a rare disease where a vermiform appendix is found within an inguinal hernia sac. It is reported in the literature as having an incidence between 0.4%–1.0% of reported hernia cases. Typically, an incidental finding, Amyand's hernia is consequently found more frequently intra-operatively rather than preoperatively. This case is a recount of a 56-year-old male, who presented in an outpatient setting for the evaluation of right inguinal pain and bulge. The patient was diagnosed with a vermiform appendix within the indirect hernia. The patient underwent elective repair of his inguinal hernia via Transabdominal Preperitoneal (TAPP) approach of the hernia with avoidance of appendectomy. An Amyand's hernia presents a challenging diagnosis and the treatment algorithm is contingent on the condition of the appendix in individual cases. This case presents a Type 1 Amyand's hernia that was repaired through laparoscopic approach using prosthetic mesh. The aim of this case study highlights the approach to surgical decision making in the diagnosis and treatment of Amyand's hernia proposed in the current literature. This case presents a rare condition known as Amyand's hernia followed by a discussion on the epidemiology, diagnostic workup, and treatment options. Treatment is dependent on the state of the appendix found in the hernia sac and the clinical scenario. Comprehensive literature review shows that the true prevalence of this disease is lower than classically described and still has no clear standardized approaches. [ABSTRACT FROM AUTHOR]

Background. Amyand's hernia is rarely noted in children, and appendicitis caused by a foreign body in Amyand's hernia is even rarer. Case. A 2-year-old girl presented with recurrent conglomerate lymph node enlargements and an abscess in the right groin existing for one year despite medical treatment. Direct radiography revealed a foreign body in the right inguinal region. Computed tomography showed a foreign body and soft tissue inflammation in the inguinal canal. Laparotomy was performed, and Amyand's hernia was diagnosed. A foreign body was found in the lumen of the appendix vermiformis causing perforated appendicitis. This case is presented because of its rarity and unusual clinical presentation. Conclusion. Amyand's hernia should be considered in paediatric cases with the history of recurrent inguinal abscesses.

• The type 2 myocardial infarction is an imbalance in the supply of oxygen to myocardium not related by an atherothrombotic disease which can be caused by an acute abdomen. • The Amyand's Hernia with an myocardial ischemic pathology is notoriously uncommon in the surgical setting being of high mortality for the patient. • Although the holistic approach of patients with acute abdomen is the work of the surgeon, is important the fact of knowing the different patterns of clinical presentation of pathologies that not corresponding to the surgical specialty. Type 2 myocardial infarction (MIT2) is characterized by higher mortality rates compared to conventional type 1 infarction according to the European Society of Cardiology (ESC) in 2018. The purpose of this case is to identify appropriate therapeutic measures. A case of an Amyand's Hernia that produced an MIT2 is described in this work. A 77-year-old male was admitted to our emergency department for acute abdominal pain in the right lower quadrant associated with the presence of an ipsilateral inguinal hernia with signs of peritoneal irritation, while complaining of chest pain. A positive troponin indicated the presence of myocardial infarction. A laparotomy was performed with the finding of an incarcerated right inguino-scrotal hernia that contained the gangrenous and perforated cecal appendix (Amyand hernia type 3). The treatment consisted of surgical correction of the hernia, an appendectomy, antibiotics and support in the intensive care unit with a positive outcome. The diagnosis of Amyand hernia type 3 was established intraoperatively, and by imaging, confirming the presence of an MIT2 according to the criteria of the fourth definition of ECS infarction. In the surgical environment it is strange to find patients who present with acute abdominal pain and a myocardial infarction at the same time. It is necessary for the consultant to recognize these two entities to make a correct diagnosis and provide timely treatment to reduce any possibility of patient mortality. [ABSTRACT FROM AUTHOR]

Background: Amyand’s hernia (AH) is defined as protrusion of the vermiform appendix within the sac of the inguinal hernia and usually misdiagnosed as obstructed hernia. It is more common in pediatric patients but there are controversies about dealing with the normally looking appendix in AH. The aim of this study is to present our experience in the management of AH and highlights the difference in dealing with normally looking appendix between pediatric and adult patients. Patients’ demographics, intraoperative, and postoperative outcome were reported and analyzed. Results: This is a retrospective analysis of 12 pediatric patients aged between 15 days and 5 years presented with AH and operated in tertiary referral hospital over 10 years. This study included 10 males and 2 females. The median age at the operation was 7 months. Eleven patients were operated using conventional technique, and only one patient was operated using laparoscopy. In 11 patients, the appendix was looking normal and was reduced without appendectomy, and the hernia was repaired. Appendectomy was done in one patient presented with AH containing inflamed appendix. The postoperative course was uneventful in all cases. Conclusions: There is a difference in the management of pediatric and adult patients presenting with AH, and appendectomy is not mandatory in normally looking appendix in pediatric patients.

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. 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. 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. 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. • Amyand's hernia is a rare finding accounting for less than 1 % of inguinal hernias. • Isolation of the appendix from the rest of the gastrointestinal tract could add to the confusion in clinical diagnosis. • Ultrasonography or computed tomography (CT) scan aid in diagnosis • The management of Amyand's hernia should be tailored according to the pathology encountered. • Though the clinical presentation may be variable and diagnosis difficult, treatment should not be delayed.

Amyand's hernia with an inflamed or perforated appendix is rare with incidence of 0.1 % and 0.01 % of cases respectively. It has been described in conjunction with cecal perforation, cholecystitis and ureterolithiasis. Yet, its association with acute sigmoid diverticulitis has never been reported before. A 57-year-old male presented to the emergency department with acute abdomen and an indurated right inguinal mass. A preoperative computed tomography (CT) scan reported a giant inflamed sigmoid diverticulum and an Amyand's hernia with a complicated appendicitis. The patient was taken to the operating room and a midline laparotomy incision was made. A giant sigmoid diverticulum with ischemic patches was encountered. The cecal appendix was found inside the right inguinal canal, with a perforation in its distal third. A Hartmann's procedure, appendicectomy and non-mesh inguinal hernia repair was accomplished. Case reports of Amyand's hernia in patients with simultaneous abdominal conditions are scarce. Symptoms in these patients could be various and may lead to preoperative imaging and diagnosis. In this case acute abdomen in physical examination demanded imaging analysis and a preoperative diagnosis of acute diverticulitis and Amyand's hernia with a perforated appendicitis was made. Amyand's hernia with acute perforated appendicitis is a rare entity. CT scan is useful for diagnosis of Amyand's hernia and associated conditions. Preoperative diagnosis of Amyand's hernia and concomitant abdominal disease aids in the therapeutic approach and management. To our knowledge this is the first case report of an Amyand's hernia in a patient with acute diverticulitis. • Amyand's hernia with a perforated appendix is very rare. • First case report in conjunction with acute diverticulitis. • Computed tomography scan is useful for preoperative diagnosis of Amyand's hernia and associated conditions.

• An appendix incarcerated in the inguinal hernia is defined as Amyand's hernia. • Preoperative diagnosis of Amyand's hernia is feasible with ultrasound and CT. • Laparoscopy for diagnostic and therapeutic purposes has been on an upward trajectory. • A potential total laparoscopy treatment strategy for Amyand's hernia was proposed, with fair outcomes. The presence of a vermiform appendix in an inguinal hernia sac is known as Amyand's hernia. It is even rarer with complicated appendicitis. Formerly it was treated via an open groin approach; recently there are new trends involving the use of laparoscopy for reduction and management of appendix. Conversely the role of laparoscopy in the following hernia repair was less discussed, with no standard care. We reported a case of Amyand's hernia complicated with appendix which was managed via a total laparoscopic strategy. A 49-year-old male presented with right groin mass with progressive pain for 3 days. Physical exams revealed incarcerated right inguinal hernia. Amyand's hernia with acute appendicitis was diagnosed preoperatively via computed tomography (CT). Emergent diagnostic laparoscopy was performed. Appendix was reduced, with appendectomy justified for signs of appendicitis. An interval total extraperitoneal (TEP) hernioplasty was performed 3 month later, with no adverse events postoperatively. In virtue of previous literature, we proposed a total laparoscopic strategy for Amyand's hernia which consists of transabdominal diagnostic laparoscopy, management of appendix, and either immediate or elective laparoscopic hernioplasty, based on status of appendix. This laparoscopic treatment strategy is feasible for Amyand's hernia, with minimized risk of surgical site infection (SSI), fair recovery and cosmesis. [ABSTRACT FROM AUTHOR]

Hernias containing the vermiform appendix are very rare. The more common of these have eponyms, such as Amyand's hernia (incidence of 0.5–1 %) and de Garengeot's hernia (incidence of 0.8–1 %). Laparoscopic port site hernias containing the vermiform appendix are even more obscure with only seven previously reported cases. A 71-year-old male presented with a palpable, non-reducible right lateral periumbilical mass, diagnosed preoperatively as an irreducible hernia at a port site from prior laparoscopic surgery. He had previously undergone laparoscopic bilateral inguinal hernia repairs with the 10 mm right lateral periumbilical port site defect within the musculoaponeurotic abdominal wall. There are recommendations regarding the closure of most 10–12 mm port sites, and all 15 mm port sites, given most port site hernias are associated with larger trocars. It is reasonable to conclude that if our patient's 10 mm right lateral periumbilical port site received fascial closure, the resultant hernia may have been prevented. Fascial closure of port sites >5 mm poses an easy and effective way to reduce risk of port site hernias as well as other potential complications, therein reducing readmission, need for additional surgery, and improving patient quality of life. • Laparoscopic port site hernias containing the vermiform appendix are very rare. • Fascial closure of >5 mm port sites may reduce the risk of port site hernias. • Review, education, and revision of guidelines for port site closure following laparoscopic and robotic-assisted procedures to improve patient outcomes and quality of life.

Amyand's hernia is a rare condition in which the appendix is situated inside an inguinal hernia sac. It occurs in less than 1 % of all inguinal hernias, and preoperative diagnosis is often challenging, even with the aid of ultrasonography or computed tomography. The course of treatment depends on the degree of inflammation of the appendix. In this report, we present a case of Amyand's hernia that was discovered during elective inguinal hernia repair. We are presenting a case of a 65-year-old man who complained of right inguinal swelling and pain for one week. Upon clinical examination, a nontender and reducible mass was discovered in his right inguinal region. Further ultrasound examination suggested the presence of a right inguinal hernia, without any additional notable findings. During the surgery, the appendix was found to be present inside the indirect inguinal hernia sac, and due to its normal condition, the hernia was reduced, and a prosthetic mesh was placed. Amyand's hernia is a rare form of inguinal hernia, predominantly found in men, with the appendix being trapped within the inguinal canal. The clinical presentation and treatment depend on the appendix's inflammation, and while ultrasonography is commonly used for diagnosis, preoperative detection of Amyand's hernia is often challenging. Amyand's hernia is a rare but potentially life-threatening condition. A high index of suspicion is required to make the diagnosis. Surgical intervention is the treatment of choice, and In the absence of complications, the prognosis is favorable. • Amyand's hernia is a rare condition in which the appendix is inside an inguinal hernia sac. • Preoperative diagnosis of this condition is often challenging, even with imaging aids. • Surgical intervention is the treatment of choice for Amyand's hernia, and the prognosis is favorable in the absence of complications. • The presented case involved a 65-year-old man with a nontender and reducible mass in his right inguinal region. • The appendix was found inside the indirect hernia sac, and the hernia was reduced and a prosthetic mesh was placed.

Amyand's hernia (AH) is a rare type of inguinal hernia that occurs when the appendix is trapped within the hernia sac. AH accounts for approximately 1% of all inguinal hernias. However, there is currently no comprehensive review on the manifestation of AH in preterm infants. A male preterm infant, born at 31+5 weeks' gestational age with a birthweight of 1040 g, presented with a right inguinal mass at 39 days of life. The inguinal mass was firm, irreducible and erythematous. The infant also exhibited symptoms of fever and poor feeding. An abdominal X-ray showed an obstructive ileus consistent with clusters of cyst-like gas bubbles suggesting pneumatosis intestinalis. Recognizing the urgent need for intervention, emergent surgery was performed. A transverse incision along the right inguinal crease. An intraoperative exploration revealed a gangrenous appendix within the hernia which indicating AH. Herniorrhaphy and appendectomy were successfully performed without any postoperative complications. Feeding was resumed 8 days after the surgery, and the infant was discharged soon with full recovery. AH is characterized by an irreducible inguinal mass that is predominantly found on the right side in preterm infants, especially males. In less mature infants, the manifestation of AH may be more severe. Therefore, AH should be considered in the differential diagnosis of infants with abdominal emergencies, and careful intra-operative assessment is essential. AH typically requires less complex treatment and has a favorable prognosis compared to other abdominal conditions in preterm infants. [ABSTRACT FROM AUTHOR]

Amyand's Hernia (AH) is a rare entity described as the presence of the vermiform appendix in an inguinal hernial sac. Though its prevalence is three times more in children than adults, owing to the presence of patent processus vaginalis, its occurrence with acute appendicitis is more uncommon in children, especially in infants. Seldom diagnosed correctly ahead of surgical exploration, it is often clinically diagnosed as an incarcerated inguinal hernia or as a case of acute scrotum. The management of such cases depends upon the per-operative findings. In this series, we report four cases of AH treated at King Saud Medical City Hospital Riyadh between 2018 and 2022. All the four patients were male and three of them were infants. Three patients had right sided hernia, while one had bilateral inguinal hernia. One of the patients was diagnosed with strangulated hernia and upon exploration it was AH with acute appendicitis and appendectomy was done. One child had recurrent, irreducible hernia and upon exploration, found appendix densely adherent to the hernial sac. Another patient had early suppurative inflammation at the tip, while the patient with bilateral hernias had appendix adherent to the right hernial sac. In all our cases appendectomy was performed either due to inflammation or adhesions. There is a rarity of this condition and few cases have been reported in the literature. Such cases need to be reported to keep the surgeons aware of this condition and its different manifestations. Herein, we aim to share our experience of four cases of AH with varied presentations and a literature review. [ABSTRACT FROM AUTHOR]

Introduction Amyand's hernia is a rare condition of inguinal hernia in which the appendix is incarcerated within the hernia sac through the internal ring. Complications include acute appendicitis and perforated appendicitis, which are rare in incidence, accounting for about 0.1% of cases. 1 These complications prove a diagnostic challenge due to their vague clinical presentation and atypical laboratory and radiological findings. Until recently, open appendectomy was the mainstay of treatment. Laparoscopic surgery offers a less invasive approach to confirming a diagnosis and serving as a therapeutic tool in equivocal cases. Case presentation We report a case of a previously healthy 20-year-old male presenting with atypical signs and symptoms, as well as blood investigation results, and radiological findings of a perforated appendix within an Amyand’s hernia. The patient was successfully managed using a minimally invasive laparoscopic appendectomy approach. Discussion Until recently, open appendectomy was considered the mainstay in the management of complicated Amyand’s hernia. Laparoscopic surgery provides a new avenue for dealing with diagnostic uncertainty with advantages including faster recovery time, reduced hospital stay, and better quality of life. Conclusion This case report highlights the concealing effects of an Amyand’s hernia on a perforated appendix, the considerations required when an equivocal diagnosis present and the safe use of the minimally invasive laparoscopic surgery in the treatment of this rare condition.

Amyand's hernia is defined as the presence of a normal or inflamed appendix vermiformis within the inguinal hernia sac and was first described by Claudius Amyand. Most cases of Amyand's hernia are seen on the right side associated with the normal anatomy of the appendix. Diagnosis is usually made during hernia surgery. In this study, a rare case is reported of a patient operated on for left-side incarcerated inguinal hernia and determined with acute appendicitis within the hernia sac. [ABSTRACT FROM AUTHOR]

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. 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. 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. 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's hernia is an appendix incarcerated within the inguinal hernia sac. • While inguinal hernias are common, Amyand's hernia is rare. • Co-operating Amyand's hernia and contralateral recurrent inguinal hernia is complex. • For concurrent operation, a surgical plan should be preoperatively established. • If planned surgery is impossible, alternatives should be considered during surgery.

The patient was an 11-month-old boy. He has been followed up at an outpatient clinic for inguinal hernia. He visited at our emergency room because of multiple episodes of vomiting. After receiving a diagnosis of incarcerated hernia, he underwent emergency surgery under general anesthesia. Intraoperative findings showed that not only the appendix but also the cecum, ascending colon, and end of the ileum had herniated, so we diagnosed him with expansive Amyand's hernia. None of the intestine was necrotic, and intestinal resection was not necessary, but there was significant ileocecal dilatation. Therefore, we resected the appendix and inserted a flexible catheter through the root of appendix to decompress the ileocecal lumen. If the ultrasound sonography at outpatient clinic had shown an appendix-like intestine with proper attention, we may have been able to diagnose him with expansive Amyand's hernia. It is crucial to check the diagnosis of hernia but also detailed contents of the hernia sac carefully by ultrasound sonography. If the appendix is confirmed with the intestine in the hernia sac, we should consider early elective surgery to avoid an emergency operation. • Amyand's hernia with herniation of the ileocecum must be diagnosed before incarceration occurs. • In inguinal hernia, we must try to detect the appendix as evidence of ileocecal herniation. • Ultrasonography at the time of incarceration shows significant edema, which often makes it difficult to detect the appendix.

Introduction de Garengeot hernia is described as the presence of an appendix in a femoral hernia. This rare hernia usually presents with both diagnostic and therapeutic dilemmas. Presentation of case We report a case of a 59 year-old woman with a one-year history of a right irreducible femoral hernia. She underwent diagnostic laparoscopy with an intraoperative diagnosis of de Garengeot hernia. This was followed by a laparoscopic transabdominal preperitoneal (TAPP) approach for hernia repair. Discussion The long-standing presentation of de Garengeot hernia is seldomly reported in literature. There has been no standard approach of treatment for de Garengeot hernias described, possibly due to the rarity of this condition. The unusual presentation of the hernia prompted us to undergo a diagnostic laparoscopy first, during which the appendix was seen incarcerated in a femoral hernia sac. We were easily able to proceed for a laparoscopic TAPP approach for hernia repair without the need for conversion to an open repair. Conclusion We were able to obtain an accurate diagnosis of an appendix within a long-standing irreducible femoral hernia through diagnostic laparoscopy followed by transabdominal preperitoneal (TAPP) approach for hernia repair. We would like to underline the usefulness of laparoscopy as a valuable tool in the diagnosis and treatment of this unusual presentation of groin hernias. [ABSTRACT FROM AUTHOR]

Abstract Introduction Inguinal hernia may contain vermiform appendix in very rare cases. This particular condition is known as Amyand's hernia and it has an incidence of 1%. Diagnosis is very difficult preoperatively, so it is usually an incidental finding. Presentation of case We report a case of a 80 year old man with an irreducible mass in right inguinal region. During surgical procedure an Amyand's hernia was identified and we performed hernioplasty sec Trabucco and appendectomy. Discussion According to Losanoff and Basson classification, our case was type 1 and its management is very controversial. Conclusion Surgical treatment depends on surgeon's experience and on clinical evaluation because there are many factors that may increase morbidity and mortality. [ABSTRACT FROM AUTHOR]

Introduction An inguinal hernia with an incarcerated appendix is defined as Amyand’s hernia, and it is relatively rare. Amyand’s hernia complicated with appendicitis, especially perforated appendicitis, is even rarer. Postoperative surgical site infection (SSI) is a dangerous complication, especially in Amyand’s hernia with appendix perforation. The selection of an appropriate surgical approach is necessary to prevent postoperative SSI. Here, we report a case of Amyand’s hernia complicated with appendix perforation that was successfully managed using a two-stage surgical approach consisting of laparoscopic appendectomy followed by elective inguinal hernioplasty. Presentation of case A 70-year-old male presented with fever and right lower quadrant pain from the day before. After the patient was diagnosed with acute appendicitis within a right inguinal hernia, emergency laparoscopy was performed. The appendix was incarcerated in the right internal inguinal ring and perforated at the base. We decided to take a two-stage surgical approach to avoid postoperative SSI and performed only laparoscopic appendectomy. No postoperative complications occurred. Inguinal hernioplasty was performed 1 month after the first operation. There were no adhesions in the preperitoneal space, and no adverse events occurred postoperatively. Conclusions A two-stage surgical approach consisting of laparoscopic appendectomy followed by elective inguinal hernioplasty was used successfully to treat Amyand’s hernia complicated with appendix perforation without causing postoperative SSI.

Introduction Amyand’s hernia is an inguinal hernia containing the caecal appendix. It is usually an intraoperative finding, although it can be diagnosed preoperatively with radiologic examinations, which would show a tubular structure inside the inguinal canal. Presentation of case A male patient presented to the emergency department complaining of abdominal pain in the right lower quadrant. He had been orchidectomized during his childhood due to cryptorchidism, and had been under antibiotic treatment a week before due to a suspected gonorrhoea. A small irreductible mass was found in the right groin. Blood tests showed leucocytosis and elevated CRP. A CT-scan was performed, reporting a tubular structure with a blind end entering the inguinal canal that seemed to be the appendix. Single-port laparoscopic exploration was indicated, and a right vasitis was found instead of an Amyand’s hernia. After the operation, the patient explained that he had not taken the antibiotics for the gonorrhoea. Discussion Untreated gonorrhoea causes ascendant vasitis and orchyepididimitis. In the present case, since the patient did not have testicles, the inflamed vas deferens mimicked the Appendix inside the inguinal canal. If the patient had told the truth about the untreated gonorrhoea, maybe the condition would have been suspected and no radiological examinations would have been performed, which subsequently lead to an unnecessary operation. Conclusion Presently, Amyand’s hernia is more frequently diagnosed preoperatively than intraoperatively. However when an Amyand’s hernia is preoperatively suspected, the possibility of a vasitis should always be ruled out in order to avoid unnecessary operations. [ABSTRACT FROM AUTHOR]

Purpose Presence of the vermiform appendix in an inguinal hernia sac is known as Amyand's hernia. This may present as a tender inguinal swelling and is often misdiagnosed as irreducible or strangulated hernia. Methods Between January 2003 and December 2013 we treated 4498 patients with inguinal hernias and performed 3267 appendectomies. Among these; 46 had an Amyand's hernia. Age, sex, presenting symptoms, treatment modality, histopathological findings, duration of hospitalization, and post-surgical outcomes were analyzed retrospectively. Results All patients were boys. The mean age was 16.7 months (15 days–8 years). 37 (80.4%) right, 2 (4.3%) left and 7 (15.2%) bilateral hernioplasties were performed. Nine patients underwent emergency surgery with an initial diagnosis of incarcerated hernia; Amyand's hernia was an incidental finding in the remaining 37 patients. Operative findings included 33 normal appendices, 9 inflamed appendices, one perforated appendix, and three appendices adherent to the hernia sac. Eighteen patients had appendectomy during hernia repair, and the other 33 had hernia repair without appendectomy. None of the patients developed recurrent hernia or appendicitis within the follow-up period. Conclusion In Amyand's hernia the appendix should be examined carefully. A classification of Amyand's hernia according to the presenting symptoms and inflammatory status of the appendix may help to determine whether or not to proceed with appendectomy.

Introduction Inguinal hernias containing the appendix are described as Amyand’s hernias. The surgical approach to these types of hernias is dependent on the type present and associated intra-operative findings. Presentation of case We present a case of complicated type IV Amyand’s hernia, which was managed though combined abdominal and inguinal approach. Though the patient had a prolonged post-operative course due to pulmonary embolism, he progressed to full recovery. Discussion The different grades of Amyand’s hernia are repaired in varying ways, including laparoscopic and open approaches with or without mesh. The type of repair must be tailored to the patient and disease process. Conclusion Primary repair of a perforated Amyand’s hernia provides adequate strength with decreased risk of infection due to synthetic material. [ABSTRACT FROM AUTHOR]

Congenital hernias occur 70% on the right side, 25% on the left side, and approximately 5% bilaterally. The finding of a congenital Amyand's hernia is of interest, especially in patients who do not present risk factors associated with connective tissue disorders, ascitic conditions, fetal developmental disorders or any condition that increases abdominal pressure. Male patient, 6 months old, was brought to the pediatric surgery department due to a visible mass in the bilateral inguinal region, which protruded with crying. The parents report that he was a 36-week preterm, low birth weight, monochorionic monoamniotic twin with bilateral congenital inguinal hernia. An open herniorrhaphy was performed, showing a left communicating hydrocele with an indirect left inguinal hernia and right communicating hydrocele with indirect inguinal hernia containing cecal appendix with no signs of inflammation. The most common clinical presentation is the presence of a reducible or irreducible mass, erythema and/or inguino-scrotal edema, irritability manifested by crying and recurrent pain in older infants. This condition may be associated with cryptorchidism, intrauterine structural developmental disorder, and the presence of fistulas. Appendectomy and traditional hernia reduction are the most common surgical approach. The evolution of this condition is favorable with extremely low complication rates. Amyand's hernia in the neonate is a rare presenting condition, which frequently involves nearby structures with risk of inflammation, incarceration and perforation, so repair should be performed early. • Currently there are controversies in the approach of congenital inguinal hernias. • The overall outcome in the management of congenital hernia is favorable. • Traditional hernia management for congenital Amyand's hernia has good results.

Amyand's hernia (AH) is a form of inguinal hernia which is consider as very rare and this type of hernia occurred up to 1% of all inguinal hernia cases. In this type of inguinal hernia, the content of hernia sac is appendix. Most patient with AH often remains asymptomatic and diagnosed intraoperatively. The diagnosis is challenging, since needs a high index of suspicion and imaging is key. Surgery is the mainstay management. We report a case of Amyand's hernia that was managed operatively in our medium complex public institution. A 28 year's old man with normal body mass index (BMI) who had a history of right-side reducible linguino-scrotal swelling for 8 years, was admitted for elective right inguinal hernia repair. Two weeks back before admission, he noticed that swelling was slightly painful. Ultrasound of the abdomen reported normal findings. There was no history of abdominal pain and vomiting. Laboratory parameters were within normal limit. So, with a diagnosis of right sided partially reducible, incomplete, and indirect inguinal hernia, patient was operated for open hernia repair surgery, intra operatively we found dense adhesions within the sac, adhesions were released which revealed herniation of appendix into the inguinal canal. Appendix was mildly congested without gross evidence of inflammation. Hence, in view of noninflamed appendix, preperitoneal mesh (polypropylene) hernioplasty from Lichtenstein tension-free mesh repair was performed with appendicectomy. Postoperative period was uneventful, patient discharged at second day. Amyand's hernia is very uncommon and characterized by the presence of the appendix in the hernia sac and it is 0.4–1% of all inguinal hernia cases, literature review also showed that incidence of Amyand's hernia is very rare, whereas only 0.1% of cases complicate into acute appendicitis due to late presentation and missed diagnosis. Amyand's hernia (AH) makes up only a small proportion of most inguinal hernia cases, and its diagnosis is usually based on incidental finding intra-operatively. This condition may remain asymptomatic and behave like a normal inguinal hernia. Management of this type of hernia should be individualized according to appendix's inflammation stage, presence of abdominal sepsis and co-morbidity. With this approach it enables surgeons to manage more variations of Amyand's hernia. Laparoscopy for dealing Amyand's hernia is frequently diagnostic as well as therapeutic. [ABSTRACT FROM AUTHOR]

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. 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. 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. 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. [ABSTRACT FROM AUTHOR]

• Amyand's hernia is an inguinal hernia that contains vermiform appendix in its sac. Diagnosis is, in the majority of cases, intrasurgical. • Many authors suggest that prophylactic appendectomy is not necessary when the appendix is found without signs of inflammation. • Adenocarcinoma of the appendix is extremely rare neoplasm. Right hemicolectomy is the treatment of choice for such tumors. • The evidence concerning hernial repair without mesh in the context of potential contamination is controversial. Inguinal hernia is one of the most common surgical problems, often posing technical challenges even to expert surgeons. Amyand's hernia (AH) is an inguinal hernia whose sac contains the vermiform appendix. Primary appendiceal neoplasms are rare. We report the case of an appendiceal adenocarcinoma within an Amyand's hernia, presenting as an incarcerated right inguinal hernia. A 87-year-old male presented in the emergency department due to a persistent right inguinal pain. Clinical examination revealed a tender right groin mass. Under the diagnosis of an right inguinal hernia, an operation was taken. Intraoperatively, an inflamed appendix and a part of the cecum were found in the hernia sac. The operation was completed with an ileocecal resection and a modified Bassini hernia repair. Histological examination revealed a adenocarcinoma of the appendix. Amyand's hernia is an inguinal hernia that contains vermiform appendix in its sac. It consists 1% of all inguinal hernias while appendicitis in an Amyand's hernia accounts for 0.1% of all appendicitis cases. Adenocarcinomas of the appendix are even rarer, accounting for 0.2% to 0.5% of all intestinal malignancies, and 4%–6% of primary appendiceal neoplasms. Diagnosis is usually established intraoperatively. A malignancy of the appendix should always be in the differential diagnosis of a right inguinal mass, in order to provide optimum surgical treatment. [ABSTRACT FROM AUTHOR]

Amyand's hernia is defined as inguinal hernia in which vermiform appendix is contained in the hernia sac. It is predominantly found on right side due to the anatomical position of the vermiform appendix and left-sided Amyand's hernia is extremely rare. Herein, we report a case of left-sided Amyand's hernia with bilateral inguinal hernia in a 10-month-old boy. The left groin mass was firm and mobile, with skin erythema. However, the mass could not be completely incarcerated into the abdominal cavity. A diagnosis of left incarcerated inguinal hernia was made, and laparotomy was performed. For the laparotomy, an oblique incision was made on the left groin, and the inguinal canal was opened in accordance with the usual inguinal hernia repair. The hernia sac contained the appendix, ileum, cecum, and ascending colon. [ABSTRACT FROM AUTHOR]

Abstract: Amyand''s hernia is a rare form of inguinal hernia in which an inflamed appendix is incarcerated in a hernial sac. The clinical presentation of Amyand''s hernia varies, depending on the extent of inflammation involved in the hernial sac and the presence or absence of a scrotal abscess. If a scrotal abscess is present, this usually indicates that the appendix in the hernial sac is perforated. However, without the availability of computed tomography (CT) scans, the condition is often preoperatively misdiagnosed as a strangulated inguinal hernia. We describe a rare case of a 64-year-old man who presented at our emergency room complaining of scrotal swelling and pain. Diagnosis of Amyand''s hernia with a scrotal abscess was confirmed preoperatively by CT scan. [Copyright &y& Elsevier]

Abstract: Amyand''s hernia is a rare hernia in which an incarcerated or perforated appendix is found in the right inguinal canal. This case report looks at the clinical presentation, the modalities for preoperative evaluation, and finally a combined approach of laparoscopic appendectomy and open repair of the hernia. To our knowledge, this is the first report of this type of management, and we feel that it is a safe and effective option. [Copyright &y& Elsevier]

Amyand's hernia is an exceedingly rare condition in which the appendix is found in an inguinal hernia. The appendix can be normal, inflamed, infected, or perforated. Here, we present a case of perforated appendicitis in an Amyand's hernia in an extremely preterm infant with subsequent post-operative complications including necrotic bowel and venous thrombosis of the mesentery. This article stresses the importance of complications that can arise in Amyand's hernia, especially in an extremely preterm infant. [ABSTRACT FROM AUTHOR]

The presence of a vermiform appendix in an inguinal hernia sac is known as Amyand's hernia. It is an uncommon and rare condition estimated to be found in approximately 1 % of hernia. However, in just 0.08 %, the condition is complicated by an acute appendicitis. The clinical presentation varies, depending on the extent of inflammation of the appendix, and is most often misdiagnosed as an incarcerated inguinal hernia. As such, it is rarely recognized prior to surgical exploration. We report a case of Amyand’s hernia in a 2-month-old male, who presented as a right-sided congenital hernia with pain in the right groin. He underwent herniotomy, which revealed that the hernia sac containing elongated inflamed appendix appeared with some adhesions to sac, lying in the inguinal canal. [ABSTRACT FROM AUTHOR]

Abstract: In pediatric surgical practice, finding of the vermiform appendix in an inguinal hernia sac is not that uncommon; however, a perforation is rare. There are only a few case reports of a perforated appendix with periappendicular abscess in the inguinal hernial sac in a neonate. We report an unusual case of inguinal hernia containing a perforated appendix that was clinically mimicking testicular torsion of the undescended testis. [Copyright &y& Elsevier]
