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. [ABSTRACT FROM AUTHOR]

Background: The rate of emergent groin hernia repair in developing countries is poorly understood.Materials and Methods: A retrospective analysis of groin hernia repairs performed at a county hospital in Guatemala [Hospital Nacional de San Benito (HSNB)] was undertaken and compared to a literature review in developed countries. Patients with incarcerated hernias were interviewed to determine factors related to late presentation.Results: Twenty-five percent of patients with groin hernias in this analysis presented at HNSB emergently (vs. 2.5-7.7% in developed countries). Most patients were male in their fifth decade of life. Ten percent of hernias were femoral. There was no delay in scheduling patients for surgery presenting for elective repair. Most patients lived within 20 miles of the hospital, but only 50% of patients returned for their follow-up appointment. Most patients with an incarcerated inguinal hernia (56%) did not seek medical attention because of family obligations, but when they did, this decision was influence by their children (66%). None of the patients presenting with an incarcerated hernia had education past secondary school. In fact, most (56%) did not have any form formal education. Nearly 90% of patients who had an incarcerated hernia repaired thought that the hospital provided good-to-excellent care.Conclusion: A high number of patients present emergently for groin hernia repair at a county hospital in Guatemala compared to developed countries. Our data suggest that emergent hernias are likely the result of patient-related issues rather than health care system limitations. [ABSTRACT FROM AUTHOR]

The article describes the case of a 71-year-old man who was taken to the emergency department with swelling in the right inguinal region after heavy lifting. He already went through a left inguinal hernia repair based on his medical history. He was treated by performing a combined laparoscopic and open approach using a mesh repair after determining that the patient is suffering with a type 2 Amyand's hernia.

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. Its clinical image is identical to that of an incarcerated or perforated inguinal hernia. Diagnosis is usually established intraoperatively. Hernioplasty (with or without mesh repair and with or without appendectomy) is the treatment of choice. According to Losannof and Basson's criteria, performance of appendectomy shall depend on vermiform appendix's inflammation status. In this case series, authors present three patients who had to undergo prophylactic appendectomy because of medical conditions, unrelated to appendix's inflammation status thus escaping from therapeutic frame set by Losanoff and Basson's criteria.

Introduction: Inguinal hernia is one of the most common operations and 1% of the cases contain appendix in the hernial sac, which is known as Amyand's hernia. Inflamed appendix and its presence in recurrent inguinal hernia is a rare encounter in general surgery. The management of Amyand's hernia is not straightforward without awareness. Methods: Recurrent inguinal hernia with Amyand's hernia history, clinical features and management was studied and compared with the present literature. We have discussed the management options and an approach using a Medline literature review. Results: An 80-year-old gentleman who had a right-side inguinal hernia operated 40 years ago presented with a right groin swelling and increasing redness associated with pain for 3 days. Clinical signs and symptoms were in favour of strangulated inguinal hernia. He was operated and appendicectomy was done for inflamed non-perforated appendicitis. Prolene mesh repair was done and he was treated with a full course of antibiotics. Discussion: Amyand's hernia is difficult to diagnose pre-operatively and its presence in recurrent hernia has only been reported once before. The management of Amyand's hernia is not straightforward in most of the cases. Inflamed and perforated appendix needs to be removed. Delayed mesh repair is a better surgical option in perforated appendix cases. [ABSTRACT FROM AUTHOR]

myand's hernia is a rare presentation of an appendix within an inguinal hernia sac. It is commonly mistaken for an incarcerated or strangulated hernia. Prompt diagnosis requires awareness of this entity, as well as associated radiologic findings on computed tomography (CT) and ultrasound. Treatment includes antibiotics and surgical intervention involving appendectomy and hernia repair. We present a case of a premature infant who developed systemic symptoms after a circumcision and was eventually diagnosed with an Amyand's hernia with concurrent appendicitis. [ABSTRACT FROM AUTHOR]

Amyand’s hernia is a very rare condition with a presence of a vermiform appendix in an inguinal hernia sac. It is estimated to be found in approximately 1% of adult inguinal hernia. In this study, we report a retrospective analysis of 30 patients aged between 19 days and 8 years with an Amyand’s hernia operated in our institution from 1998 to 2009, and we reviewed the literature on the topic. Hernia repair without an appendectomy was performed in patients with normal appendix. Emergency appendectomy through herniotomy was performed in cases of inflamed and perforated appendices.

This study presents the case of a patient with necrobiosis or necrosing fascitis of the inguinal region, secondary to a complicated Amyand's hernia with a concomitant ipsilateral Richter's hernia. The patient was treated with open trans-abdominal surgery and hernia repair through the pre-peritoneal approach, plus anti-microbians, and thrice-daily wound cleansing and dressings to the inguinal region. Evolution was satisfactory. There are no reports in the literature of a case such as this. [ABSTRACT FROM AUTHOR]

The contents of an incarcerated inguinal hernia sac usually consist of small bowel or omentum. Amyand’s hernia, the situation in which appendicitis is noted in the hernia sac, is a rare occurrence. Also, neoplasms of the appendix is quite uncommon. The occurrence of these two conditions together is even more rarely reported. We report the case of a 62-year-old male with these two diseases simultaneously. Incarcerated inguinal hernia was noted before operation. Amyand’s hernia was noted during the operation. Adenocarcinoid tumor of the appendix was noted after the operation. Operative decisions were changed during the medical course. [ABSTRACT FROM AUTHOR]

Amyand’s hernia is a rare type of hernia in which the appendix is found in the inguinal canal. A case of an 8-week-old boy who was diagnosed and managed laparoscopically is presented. To the authors’ knowledge, this is the first report of emergency laparoscopic surgery for an Amyand’s hernia in a young infant. [ABSTRACT FROM AUTHOR]

Amyand’s hernia (AH) is defined as an appendix located in the inguinal hernia sac. Most cases are diagnosed intraoperatively and might undergo appendectomy besides hernia repair. Computerized tomography is effective in the preoperative diagnosis. Meanwhile, the number of reports concerning the preoperative diagnosis of AH is increasing. There is no standard protocol for the management of AH. Factors such as the presence of an inflamed appendix, contamination of the surgical field, patient age and anatomic features of the tissue are important determinants for appropriate surgery. Herein, we report an adult male patient with AH. [ABSTRACT FROM AUTHOR]

The finding of a normal or inflamed vermiform appendix within an inguinal hernia is termed Amyand's hernia. It is extremely rare in children, especially in infants and neonates. When it occurs, it is usually misdiagnosed as an irreducible or strangulated inguinal hernia, and the accurate diagnosis is made intraoperatively. We report two cases of Amyand's hernia in premature neonates. Both patients presented on admission with signs and symptoms indicating a strangulated right inguinal hernia, and the accurate diagnosis was made intraoperatively. One of them had progressed to local peritonitis. Appendicectomy and hernia repair were made at the same time through an inguinal transverse incision, and the postoperative course was uneventful in both. We point out the need to consider acute appendicitis in the differential diagnosis of strangulated right inguinal hernia. [ABSTRACT FROM AUTHOR]

We report an extremely rare case of complicated Amyand's hernia. A 61-year-old male patient was admitted with clinical signs of incarcerated right inguinal hernia and localised tenderness in the right iliac fossa. He underwent emergency surgery and the operative findings included perforated appendix and periappendicular abscess within a right inguinal hernia sac. Appendectomy and Shouldice's herniorrhaphy without prosthetic mesh placement were performed. Histology revealed the presence of a villous adenoma near the base of the appendix. We point out that although Amyand's hernia is a very rare clinical entity, it should always be considered in the differential diagnosis in cases with clinical signs of incarcerated right inguinal hernia, especially when there are no pathological findings on the abdominal X-rays.

The finding of an appendix in the hernial sac is termed Amyand's hernia. There have been a few reports of perforated appendix in the hernial sac (right-sided) mimicking testicular torsion. We report an extremely rare case of a left-sided inguinal hernial containing sac containing perforated appendix which was never thought of in the preoperative assessment. [ABSTRACT FROM AUTHOR]

Amyand’s hernia (AH) is the presence of a normal or inflamed vermiform appendix in an inguinal hernia sac. This condition is unusual in neonates and in infants, and it has not been described in premature twins. We present two 32-day-old biovular twins with a right AH, treated with sparing of the appendix and herniotomy. The correct management of AH is discussed via a brief review of the literature. [ABSTRACT FROM AUTHOR]

We report an unusual case of peri-appendicular abscess occurring in an irreducible Amyand’s hernia, managed in a primary care setting. An 84-year-old gentleman, with severe chronic obstructive airways disease, was assessed in a Primary Care surgical clinic and found to have a moderate-sized, tender, irreducible right inguinal hernia. He underwent immediate surgery under local anaesthetic. He was found to have a peri-appendicular abscess and perforated appendix within a right indirect inguinal hernia sac. Appendicectomy and sutured hernia repair were performed under local anaesthesia. [ABSTRACT FROM AUTHOR]

Amyand’s hernia is an inguinal hernia containing vermiform appendix. We report a case of this rare condition, diagnostic findings, and management considerations. A short review and history of Amyand’s hernia is presented as well. A literature search from Medline was done, and the published articles were reviewed. A case of Amyand’s hernia, which was recently managed by the authors, was studied and the data reviewed. Diagnosis of the Amyand’s hernia is usually made intraoperatively. The majority of the existing literature recommends doing open or laparoscopic appendectomy with open repair of the inguinal hernia, although some authors advise mesh repair of the hernia if the appendix is normal. Amyand’s hernia can be a challenge for the surgeon. We recommend laparoscopic appendectomy and open repair of the inguinal hernia without using mesh. [ABSTRACT FROM AUTHOR]

Presence of an appendix in a hernial sac (Amyand's hernia) is a rare entity, still rarer is an inflamed appendix within the hernial sac. An endoscopic total extraperitoneal repair of a right-sided incarcerated inguinal hernia is described. The inguinal hernial sac contained an inflamed appendix. An associated small incisional hernia at the lower end of a midline suprapubic scar for a Millin's prostatectomy was simultaneously repaired. [ABSTRACT FROM AUTHOR]

In 2000–2001 two patients with acute appendicitis in the right inguinal hernia (Amyand's hernia) and the symptoms of incarcerated hernia were operated on in emergency. One patient with the symptoms of local peritonitis was subjected to hernioplasty and appendectomy. The second underwent midline inferior laparotomy, because of diffuse peritonitis with appendectomy and hernioplasty. Both patients were operated by Shouldice's method. None of the patients developed recurrent disease. The presented cases point to the necessity of considering acute appendicitis in the differential diagnosis of incarcerated right inguinal hernia.
