INTRODUCTION<\/h1>\n

The presence of a vermiform appendix inside a hernial sac is not a common condition7<\/sup><\/span>. In the literature, the reported incidence is around 1% of all hernias6<\/sup><\/span>. It is even rarer to find an acute appendicitis inside the inguinal hernia4<\/sup><\/span>.<\/p>\n

When the cecal appendix, inflamed or not, is found in the inguinal sac, it is called an Amyand hernia5<\/sup><\/span>. This kind of hernia is more frequent in men and pre-operative diagnosis is not easy9<\/sup><\/span>. It must be suspected in patients with a tense inguinal hernia with no signs of intestinal obstruction. The appendectomy will always be carried out at the same time as the repair of the hernia.<\/p>\n

The aim of the present study is to present a case of acute appendicitis within a right inguinoscrotal hernia and to review the literature.<\/p>\n

CASE REPORT<\/h1>\n

A 35-year-old male farmworker arrived at the General Surgery Service of the Hospital Universit\u00e1rio Oswaldo Cruz, Recife, Pernambuco, Brazil. He reported the appearance of a mass in the right inguinoscrotal region for around one month without pain. Two days previously he had begun to experience epigastric pain with nausea and vomiting. He visited his local health service and received treatment for gastritis. As the pain continued and was located in the right iliac fossa, he was admitted to hospital. A physical examination revealed a heart rate of 100 bpm, a respiratory rate of 21 ipm, PA=130x80 mmHg and an inguinoscrotal hernia on the right side with slight irritation of the peritoneum. He was referred for surgery and the procedure revealed an inflamed appendix with purulent secretion at its apex within the hernial sac. As surgical access was by transverse incision of the inguinal hernia, it was decided to perform the appendectomy and the Bassini repair of the hernia simultaneously (Figure 1<\/a>). Antibiotic prophylaxis with metronidazole and ceftriaxone was carried out for 24 hours. After two days, the patient was discharged from hospital with no complications. The result of a biopsy confirmed the appendicitis.<\/p>\n

DISCUSSION<\/h1>\n

Some authors believe that a cecal appendix in an inguinal hernia was first described by De Garengeot in 173110<\/sup><\/span>. Claudius Amyand (1681-1740), a French surgeon, who was a refugee in England, was the first to perform an appendectomy13<\/sup><\/span>\u00a0,<\/sup>\u00a011<\/sup><\/span>. The appendix is found in the hernial sac in around 1% of inguinal hernias and an inflamed appendix is found in only 0.13% of cases.<\/p>\n

A variant of this, an appendix inside a femoral hernia, is called a Garengeot hernia4<\/sup><\/span>. In 1937, Ryan described 11 cases of acute appendicitis (within an inguinal hernia) among 8,692 cases of appendicitis12<\/sup><\/span>. Another author1<\/sup><\/span>\u00a0reported 10 cases of appendicitis within an inguinal hernia over nine consecutive years.<\/p>\n

The etiopathogenesis of acute appendicitis is unclear. Many authors believe there is an association between incarceration and inflammation of the cecal appendix in the hernial sac, that is, an ischemic phenomenon deriving from compression of the organ by the hernial ring leading to appendicitis14<\/sup><\/span>. Typical symptoms of acute appendicitis, such as initial epigastric pain settling later in the right iliac fossa, nausea, vomiting and anorexia may also be seen in patients with an Amyand hernia. According to the literature, fever and leukocytosis are not common in these patients13<\/sup><\/span>. Pre-operative diagnosis is unusual. In an article reviewing 50 cases of Amyand's hernia, only one case was diagnosed prior to surgery14<\/sup><\/span>.<\/p>\n

The presence of peritoneal irritation and early pain in an incarcerated hernia may suggest appendicitis inside the hernial sac. The use of imaging methods may assist diagnosis4<\/sup><\/span>.<\/p>\n

Surgery is mandatory. However, the kind of surgery recommended subject to controversy. In most circumstances, treatment involves an emergency appendectomy and repair of the hernia8<\/sup><\/span>. When there is a risk of complications, such as a pericecal abscess, the appendectomy should be pre-peritoneal to minimize possible infection of the wound and recurrence of the hernia2<\/sup><\/span>.<\/p>\n<\/div>\n
