Abstract

Femoral hernias comprise a small proportion of all groin hernias. They are more common in women and have a high rate of incarceration and strangulation, leading to emergency repair. A 61-year-old female patient was admitted to the emergency department complaining of a 2-day painful lump in the right groin, that had become more intense in the last 24 hours. Physical examination suggested the presence of a strangulated femoral hernia, and the patient underwent emergency surgical repair. Intraoperatively, the right fallopian tube was observed in the hernia sac. Since there were no signs of ischemia, the tube was reduced back into the pelvic cavity and the hernia was repaired. The postoperative period was uneventful, and the patient was discharged without complications, 3 days after surgery.

Resumo

As hérnias femorais representam uma pequena fração de todas as hérnia da região inguinal. Elas são mais comuns entre as mulheres e estão associadas a elevadas taxas de complicações, como encarceramento e estrangulamento, com necessidade de cirurgia urgente. Uma paciente do sexo feminino, de 61 anos, recorreu ao serviço de emergência por quadro de dor e tumefação da região inguinal direita com 2 dias de evolução e agravamento nas últimas 24 horas. O exame objetivo sugeria a presença de uma hérnia femoral encarcerada, e a paciente foi submetida a cirurgia urgente. Intraoperatoriamente, confirmou-se o diagnóstico de hérnia femoral encarcerada, que continha a trompa de falópio direita no interior do saco herniário. Uma vez que a que a trompa não apresentava sinais de isquemia, o conteúdo da hérnia foi reduzido, e procedeu-se à sua reparação. O período pós-operatório decorreu sem intercorrências, e a paciente teve alta no 3° dia após a cirurgia.

Introduction

Femoral hernias are relatively uncommon and account for ∼ 2% of all hernias and 2 to 8% of all groin hernias. They are mostly observed among adults (40–70 years), much more common in women than in men, and are frequently associated with incarceration and strangulation.[1] [2] [3] Increased intra-abdominal pressure, which occurs in certain conditions, such as obesity, chronic cough, heavy exercise or lifting, and pregnancy, is usually implicated.[4] [5] [6] Different contents in the hernia sac have been described in the literature, but exclusive herniation of the fallopian tube is extremely uncommon.[7] [8] We present a rare case of a 61-year-old female with a femoral incarcerated hernia containing a fallopian tube that required emergency surgical intervention at our institution.

Case Presentation

A 61-year-old female patient was admitted to the emergency department complaining of a 2-day painful lump in the right groin, which gradually became tender to palpation during the last 24 hours. She denied urinary symptoms, anorexia, nausea, or vomiting and had regular bowel function. She had no significant past medical or surgical history. On clinical examination, the patient was afebrile, her pulse rate was 83 bpm and blood pressure 132/86 mmHg. Physical examination revealed a 3 × 4 cm tender mass in the right groin, irreducible and non-pulsatile. Abdominal examination showed mild tenderness in the right iliac fossa. The leucocyte count was 7,400/μl (neutrophils: 50%), and C-reactive protein was 0.84 mg/dL. The patient underwent ultrasonography that showed “signs compatible with right femoral hernia, non-reducible, containing intestine, fat and fluid.” Abdominal and thorax X-rays were unremarkable.

Treatment

Clinical assessment suggested the presence of a strangulated femoral hernia, and the patient underwent emergency surgery. We used a lower inguinal approach and carefully exposed the femoral hernia sac. After opening the sac, we confirmed the diagnosis of femoral hernia that unexpectedly contained the right fallopian tube ([Figs. 1] and [2]). The tube was congested, but showed no signs of ischemia and was reintroduced into the pelvic cavity, without any difficulty. We excised the hernia's sac and repaired the defect using a polypropylene mesh plug.

Outcome and Follow-Up

The postoperative period was uneventful, and the patient was discharged without complications 3 days after the surgery. No signs of hernia recurrence were noted at 1-, 3-, and 6-month follow-up appointments.

Discussion

Femoral hernias comprise a small proportion of all groin hernias, accounting for ∼ 2 to 8% of cases.[2] They are 4-to-5-fold more common in women, generally occur in the elderly, and are more frequent on the right side.[1] [2] [3] [4] [5] [6] This specific type of hernia occurs when intraabdominal content protrudes through the femoral ring into the femoral canal, beneath the inguinal ligament. Because of their narrow neck and rigid ligamentous borders, they are prone to incarceration and strangulation, leading to emergency surgery in many cases.[9] [10] Femoral hernias usually contain preperitoneal fat or segments of the small bowel; nonetheless, other contents, such as stomach, colon, appendix, bladder and Meckel diverticulum have been described in the literature. Herniation of the fallopian tube or ovary is an extremely rare condition, especially in adults, due to their normal anatomical position, located at a lower level than the femoral ring.[11] Maylard[12] described one of the first cases of a femoral hernia containing the ipsilateral fallopian tube, in 1892. Since then, a few of cases have been reported, and most of them were found in the pediatric population. Typical femoral hernias present as a tender, non-reducible groin lump, with no cough impulse, situated below and lateral to the pubic tubercle. The diagnosis is generally done by physical examination; however, in some patients, imaging exams, such as abdominal X-ray, ultrasonography, CT, or MRI, may be useful in the diagnosis, especially because of the variety of possible contents.[8] [11] Preoperative diagnosis of a strangulated fallopian tube in a femoral hernia is extremely difficult, as only one case is described in the literature.[13]

Early diagnosis and surgical treatment are key factors for the prognosis, since female adnexa are particularly vulnerable to ischemia when entrapped, which may lead to an infarcted and unsalvageable ovary or fallopian tube. Therefore, female adnexa should always be considered as possible hernia contents to warrant a prompt assessment and intervention, thus avoiding the necessity of resection and preserving fertility in women of childbearing age.[11] [14] [15] Surgical approach of a femoral hernia containing female adnexa follows the same principles of any other femoral hernia treatment. There are many different repair techniques that can be divided in two main groups: tension-free mesh techniques (open or laparoscopic), or non-mesh techniques. In our case, we have decided to do a tension-free repair using a polypropylene mesh plug, known to have lower recurrence rates and associated to less short-term pain and discomfort, allowing for a faster recovery and rapid return to normal activities.[1]
