De Garengeot hernia with acute appendicitis

AIM

The presence of the appendix within a femoral hernia sac is a rare condition known as De Garengeot hernia. We report a case of De Garengeot hernia with concomitant appendicitis and a brief review of the literature on the pathogenesis, diagnosis and treatment of this uncommon condition.

CASE REPORT

A 33 year-old woman was admitted to our Surgical Unit with acute-onset pain and swelling in the right groin region. Clinical signs and ultrasound imaging suggested the presence of a strangulated femoral hernia and the patient was operated on in emergency setting. An inflamed appendix was discovered within the hernia sac. Appendectomy via McBurney incision and prosthetic repair of the femoral ring were performed. The postoperative course was uneventful and at the 2 week and 1 year follow-up no signs of wound infection and no hernia recurrence were found.

CONCLUSION

Since clinical signs are non-specific and radiological findings may often be misinterpreted, appendicitis within a femoral hernia sac is often an incidental finding during an emergency operation for strangulated femoral hernia. Appendectomy-associated hernia repair may be performed with or without prosthesis depending on the extent of surgical field contamination.

Incidence and risk factors for trocar site hernia following laparoscopic cholecystectomy: a long-term follow-up study

BACKGROUND

The aim of this retrospective study was to assess the incidence of trocar site hernias (TSH) following laparoscopic cholecystectomy (LC) through a long-term follow-up and to elucidate the significance of several technical and patient-related factors.

METHODS

A total of 313 patients submitted to LC between 2000 and 2004 were included in our study. The pneumoperitoneum was always performed by means of Hasson's technique at the umbilical site and the operative trocars were positioned using either the American technique or the French technique. Closure of the fascial defect was performed only at the umbilical site. The effects of several variables, including age, gender, size of gallstones, co-existing umbilical hernia, complexity of operation, diabetes, obesity, malnutrition, smoking, and heavy manual work on the development of TSH were assessed by univariate and multivariate models.

RESULTS

Thirteen cases of TSH (4.1 %) were detected over a mean follow-up period of 89.8 months (range: 60-128). Of these, 11 (84.6 %) developed at the umbilicus and 2 at the 10 mm subxiphoid site (15.4 %). At univariate and multivariate analysis, gallstones ≥ 2 cm (p = 0.030; OR = 9.95, p = 0.01) and obesity (p = 0.002; OR = 22.93, p < 0.01) were found to increase the likelihood of TSH development.

CONCLUSIONS

After long-term follow-up, the incidence of TSH following LC was higher than expected. The insertion of large trocars at the umbilical site plays a key role in the development of TSH. Other conditions such as obesity and large gallstones can be additional risk factors since the umbilical defect must often be widened in these cases.
