P155 DE GARENGEOT HERNIA: A CASE REPORT

Aim “The De Garengeot’s hernia, from Rene De Garengeot, who was the first to describe the appendix inside a femoral hernia sac in 1731, is a rare type of crural hernia. The diagnosis is challenging and surgery must be performed without delay. The incidence of appendicitis in this type of hernia is about 0.08-0.13%. The aim of this work is to describe our experience in the management of this rare subtype of hernia in a 82-year-old women” Material and Methods “A 82-year-old patient with a right groin bulge presented to the Emergency. At the physical examination the abdomen was treatable; there was no sign of bowel obstruction. Blood test values were normal, except for a high PCR value. The US of the groin region demonstrated a right femoral hernia containing a bowel tract, irreducible at the probe’s pressure. The patient underwent surgery, with diagnosis of De Garengeot’s hernia; a direct hernia repair followed by an open appendectomy were performed. The patient did not present any complications and was discharged on the second postoperative day” Results “The De Garengeot hernia is a rare entity that requires an early treatment; the preoperative diagnosis is difficult and often clinical features are similar to a common incarcerated hernia. There are many surgical options for the management of the De Garengeot hernia, but there is not a consensus for the best surgical approach” Conclusions “De Garengeot's hernia is rare, being indistinguishable from an incarcerated femoral hernia in general. This case report is about a De Garengeot’s hernia patient, who presented a good recovery after surgery.”

1412 De Garengeot's Hernia Complicated by Perforated Appendicitis and Groin Abscess: Report of A Rare Surgical Emergency

Introduction De Garengeot's hernia is a rare subtype of femoral hernia which contains the vermiform appendix. Acute appendicitis in a femoral hernia is even more unusual, accounting for 0.08% - 0.13% of all cases of femoral hernias. Case presentation A 91-year-old woman was referred with a painful, cellulitic right groin mass. A computed tomography scan demonstrated a right-sided femoral hernia containing a loop of bowel and a collection in the right groin containing fluid and gas. The patient had early dementia but no other major medical co-morbidities. At surgery, she was found to have perforated appendicitis in a right femoral hernia. Most of the appendix and sac had fully disintegrated, forming a large abscess cavity beneath the skin in the right groin which extended down to the upper labia majora. The appendix tip was lying deep within the abscess cavity. A modified McEvedy approach was used to access the peritoneal cavity for the appendicectomy and sutured repair of the femoral neck. The groin abscess cavity was drained and managed with a negative pressure (VAC) dressing. Discussion De Garengeot's hernia is often difficult to diagnose pre-operatively and reporting of cross-sectional imaging may not always be reliable. Currently, there is no gold standard method for repairing these hernias. However, the modified McEvedy approach is well-described and is the preferred technique for emergent femoral hernia presentations. It provides sufficient access to manage both appendicitis and the femoral hernia. Adjuncts such as negative pressures dressings may be used to manage concomitant abscess cavities.

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.

De Garengeot’s hernia in an elderly woman as a diagnostic challenge: a review of literature

De Garengeot’s hernia is the presence of an appendix in a femoral hernia and can be a rare cause of an acute groin swelling. Here, we present a case report of an elderly woman who was referred to us with a short history of a painful, tender lump in the right groin associated with nausea and vomiting. Her inflammatory markers were raised, and to establish a final diagnosis, an urgent CT scan was requested which showed a blind ending tubular structure in a hernia sac. She was taken to the theatre for urgent exploration of the groin which revealed that it was a femoral hernia, the sac of which contained gangrenous appendix, the base of which could not be accessed through the groin incision and, therefore, a lower midline laparotomy incision was made and a formal appendicectomy was done.

A Novel Approach to Managing a Strangulated De Garengeot’s Hernia

De Garengeot’s hernia, the presence of an incarcerated vermiform appendix within a femoral hernia, is a rare general surgery emergency that predominantly affects elderly female patients. Due to its rarity, there is significant variation in surgical technique; however, most case reports favor an open approach. Here we present a case of a De Garengeot’s hernia with a unique hybrid open and laparoscopic repair, utilizing the hernia defect as a port site. We will also review the relevant literature.
