P-018 ACUTE APPENDICITIS IN DE GARENGEOT'S HERNIA - A LITERATURE REVIEW

Abstract

Abstract Aim This study aims to undertake a systematic review of published data, focussing on the incidence of acute appendicitis within a de Garengeot hernia, the relationship between pre-operative diagnosis, surgical technique, incidence and surgical outcomes. Methods A PRISMA modelled literature search was carried out across PubMed, ProQuest, and BMW Case Report databases with the search terms ‘Femoral Hernia’, ‘Appendix’, ‘de Garengeot's’ in combinations, limited to English language, published between 1960 to 2019. Authors report another case study that was not included in the systematic review. Results Systematic review identified 84 published data reporting 112 such cases. 74(66%) presented with painful groin swellings. CT performed in 43(38%) accurately diagnosed de Garengeot's in 32(74%) patients. The most common surgical approach was low approach 35(31%) followed by the inguinal approach 23 (21%). 81 (72%) underwent herniorrhaphy with non-absorbable sutures and 20 had mesh repairs (18%). Ten (9%) patients were reported to have postoperative morbidity with wound infection being the most common complication and one recorded death. Conclusion Rarity of de Garengeot's hernia is shown by the limited availability of data that restricted our ability to conclude a single diagnostic pathway or a specific surgical technique for this condition. CT has shown, relatively accurate form of imaging tool, as well as Ultrasound scans in some. Sequestrated appendicectomy and hernia repair via laparoscopy is an option, however, there is lack of data to warrant its effectiveness as the surgical option of choice over an open groin approach in the presence of incarcerated groin swelling.
