Appendicitis in an obturator hernia

Subtotal Appendectomy to Treat Gangrenous Appendicitis Incarcerated in an Obturator Hernia

Obturator hernias are quite rare in the world of hernias, and one that contains an acutely inflamed appendix becomes a very rare case indeed. An obturator hernia containing the appendix has been reported only 5 times in the surgical literature. Three of those cases were in elderly women with delayed presentations and were fatal. The most recent case was in a young woman with prompt laparoscopic appendectomy and no complications. We present a case in a 25-year-old man presenting with acute appendicitis and found to be incarcerated within the obturator canal during laparoscopy. The patient was treated with a 4-day course of postoperative antibiotics and a surgical drain that was later removed who had a full recovery. We conclude that the appropriate workup includes CT imaging and treatment with laparoscopic surgery for removal of the appendix.

Connexin 43 and ATP-sensitive potassium channels crosstalk: a missing link in hypoxia/ischemia stress

Connexin 43 (Cx43) is a gap junction protein expressed in various tissues and organs of vertebrates. Besides functioning as a gap junction, Cx43 also regulates diverse cellular processes like cell growth and differentiation, cell migration, cell survival, etc. Cx43 is critical for normal cardiac functioning and is therefore abundantly expressed in cardiomyocytes. On the other hand, ATP-sensitive potassium (K_ATP) channels are metabolic sensors converting metabolic changes into electrical activity. These channels are important in maintaining the neurotransmitter release, smooth muscle relaxation, cardiac action potential repolarization, normal physiology of cellular repolarization, insulin secretion and immune function. Cx43 and K_ATP channels are part of the same signaling pathway, regulating cell survival during stress conditions and ischemia/hypoxia preconditioning. However, the underlying molecular mechanism for their combined role in ischemia/hypoxia preconditioning is largely unknown. The current review focuses on understanding the molecular mechanism responsible for the coordinated role of Cx43 and K_ATP channel protein in protecting cardiomyocytes against ischemia/hypoxia stress.

Acute appendicitis within an obturator hernia

We present the case of a 17-year-old girl who presented with the signs and symptoms of acute appendicitis; however, during laparoscopic surgery, it was found that the appendix had herniated through the obturator canal. This pathology has previously been associated with an unfavourable outcome and has been reported, in the literature, in older, emaciated women.

Amyand's hernia: a review

BACKGROUND

The presence of a vermiform appendix in an inguinal hernia sac is known as Amyand's hernia. The aim of this systematic review was to gather information concerning its prevalence, clinical image, diagnosis, and treatment.

DATA SOURCES

The MEDLINE database was thoroughly searched using the keyword "Amyand's hernia." Additional articles were gathered and evaluated.

CONCLUSIONS

The true prevalence of Amyand's hernia seems lower than classically described. Its usual clinical image is identical to that of an incarcerated hernia, and thus it is almost impossible to diagnose preoperatively, although ultrasound and computed tomography can help. Treatment includes hernioplasty with or without appendectomy and/or mesh repair depending on the vermiform appendix's inflammation status, the patient's general condition, and other factors. Amyand's hernia generally has a good prognosis, although serious complications have been described. Surgeons should be prepared if they encounter Amyand's hernia because appropriate treatment ensures hernia repair without complications and with avoidance of recurrence.
