Abstract:
Amyand's hernia is rare among inguinal hernias (< 1% of patients). Inflammation of appendix in hernial sac is observed in less than 0.1% of cases. Diagnosis of this hernia is difficult because preoperative diagnostic methods often fail to visualize appendix. Thus, final diagnosis is often established intraoperatively. The authors present successful treatment of Amyand's hernia in a 54-year-old patient with recurrent inguinal hernia and 3 previous surgical corrections (the last one 7 years ago). Hernia was characterized by periodic self-reduction of protrusion. Within 72 hours before hospitalization, there were acute pain, local skin hyperemia, and no manual reduction of protrusion. This indicated strangulation of appendix. Preoperative examination revealed signs of inflammation and dilation of inguinal canal with hernial sac. The patient was diagnosed with unilateral or unspecified inguinal hernia without obstruction or gangrene with suspected strangulation of appendix. Surgical intervention was performed using open Lichtenstein hernia repair with appendectomy. No postoperative complications were observed, and follow-up confirmed no hernia recurrence.
Insights
Amyand's hernia, a rare condition involving the appendix within an inguinal hernia sac, presents diagnostic challenges. This case highlights successful surgical repair using Lichtenstein hernia repair with appendectomy for a recurrent case.
Area of Science:
- General Surgery
- Abdominal Surgery
- Hernia Surgery
Background:
- Amyand's hernia, where the appendix is located within an inguinal hernia sac, is exceptionally rare, occurring in less than 1% of inguinal hernia cases.
- Inflammation of the appendix within the hernial sac is even rarer, seen in less than 0.1% of patients.
- Preoperative diagnosis is challenging due to the appendix's often unvisualized nature, frequently leading to intraoperative confirmation.
Purpose of the Study:
- To present the successful surgical management of a complex Amyand's hernia case.
- To illustrate the diagnostic difficulties and treatment approach for recurrent inguinal hernias complicated by appendiceal involvement.
Main Methods:
- The study involved a 54-year-old patient with a history of recurrent inguinal hernia and three prior surgical corrections.
- Preoperative assessment indicated strangulation of the appendix within the hernial sac, showing signs of inflammation and dilation.
- Surgical intervention utilized an open Lichtenstein hernia repair combined with an appendectomy.
Main Results:
- The patient underwent successful open Lichtenstein hernia repair with appendectomy.
- No postoperative complications were observed following the surgical procedure.
- Follow-up confirmed the absence of hernia recurrence, indicating a successful outcome.
Conclusions:
- Amyand's hernia, particularly in recurrent cases, requires careful surgical consideration.
- The Lichtenstein repair with appendectomy is an effective treatment for Amyand's hernia, even in complex scenarios.
- Prompt diagnosis and surgical intervention are crucial for managing strangulated appendix within a hernia sac.
