Endometriosis is defined as the growth of tissue resembling the endometrium outside the uterus. This usually occurs in or around the reproductive organs. However in rare cases, the disease can spread to the bladder, kidneys, lungs, and/or bowels, including the appendix.
It is not known how common endometriosis of the appendix is, and there is great variation in the rate of appendiceal involvement with numbers ranging from 1 to 22 percent.
The exact cause of endometriosis is not known, and it is also not known why the disease sometimes spreads to other areas such as the kidneys, diaphragm, or appendix. One hypothesis is retrograde menstruation where the menstrual blood carrying endometrial debris flows backward into the fallopian tubes and subsequently implants and forms lesions .
Other theories include :
The coelomic metaplasia theory, which suggests that the peritoneal cavity—or the space within the abdomen that contains the intestines, stomach, and liver—houses progenitor cells or cells capable of differentiating into endometrial tissue in response to a specific signal.
The induction theory, which suggests that the endometrium, or uterine lining which is shed during menstruation, produces substances to form endometriosis.
The cellular immunity theory, which suggests that alterations in the immune system allow endometrial cells to grow outside the uterus.
Appendiceal endometriosis can cause a wide range of symptoms that mimic symptoms of acute appendicitis which include a sudden pain that begins on the right side of the lower abdomen and that worsens with movement, loss of appetite, nausea, vomiting, abdominal bloating, constipation or diarrhea, and fever . However, unlike acute appendicitis, endometriosis of the appendix usually causes pain that comes and goes with the menstrual cycle.
Patients who have appendiceal endometriosis can be divided into four groups depending on their symptoms . They may experience:
the symptoms of acute appendicitis
abdominal colic, nausea, and melena, or black stools
It is difficult to diagnose endometriosis of the appendix because the symptoms are very similar to those of acute appendicitis.
One of the most important tools for diagnosing endometriosis of the appendix is a physical examination. However, imaging techniques such as CT scans can also help diagnose the condition. The surest method for a definitive diagnosis, however, is laparoscopic surgery .
It is very important that the endometriosis of the appendix is diagnosed early so that the disease can be treated appropriately. If left untreated, appendiceal endometriosis can lead to bleeding or perforation in the intestines and obstruction of the bowels .
An appendectomy (the surgical removal of the appendix) is the best way to treat appendiceal endometriosis. In more severe cases, an ileocecectomy (the surgical removal of the ileum, a part of the small intestine) or hemicolectomy (the removal of a segment of the colon) may be necessary .
An interventional clinical trial (NCT01921634) is currently recruiting an estimated 100 participants at Penn State Milton S. Hershey Medical Center in the U.S. to assess whether the incidence of appendiceal endometriosis is related to the method of pathologic analysis .
The rate of appendiceal involvement of endometriosis varies greatly, ranging from 1 percent to as high as 22 percent. Researchers hypothesize that the way in which the specimen is analyzed could partly explain this wide disparity. This clinical trial will investigate how the method of pathological analysis influences the incidence of appendiceal endometriosis.
Women aged 18 to 51 who have their appendix removed at the time of laparoscopy to treat their endometriosis and/or pelvic pain are eligible to take part in the study.
"Being a freshman in college was enough stress, the last thing I needed was this disease bringing me down. Together, Dr. Seckin, my parents, and I decided surgery was the best option. Going in with no guarantee of success I put all my trust in Dr. Seckin knowing I was in good hands. I am happy to say that now, two weeks after my surgery I feel GREAT! Dr. Seckin removed 15 suspicious adhesions and a very fatty, unhealthy, inflamed appendix. Aside from expected soreness from the surgery, I am confident that I am on the right track back to my old self. " –Anessa Marinello
There aren’t enough stars for Seckin Endometriosis. They deserve 100/ 5. I want to make sure every woman right now who is looking for help, who is looking for a doctor and is scared and confused knows this is where you need to be. It doesn’t matter if you have to come from the other side of the United States or from the other side of the world, I can guarantee it will be worth it. Every member of their…
I’ve seen many obgyns over the years explaining my monthly symptoms during my period...but eventually it became a daily struggle with these pain. It feels like a poke here and there near my right pelvic region. I was given birth control pills for the past ten years but honestly, it didn’t help at all. I was in bed whenever I had my period. I was previously sent to GI doctors for possible appendicitis but it was ruled out from imagings…
Dr.Seckin is so much more than a surgeon. His passion for helping endometriosis sufferers and determination to improve the quality of life in all of his patients is undeniable. I remember when my gynecologist first told me I needed a laparoscopy. Her exact words were "I can do the surgery, but if you were MY daughter- I'd send you to him." From the first day I met him he took the time to explain endometriosis to me since I knew…
I was there for hysterectomy but then I found out that I also had endometriosis.My both surgeries went excellent and I feel great!.I am so thankful to Dr.Seckin and all his team for making my journey smooth!
I am a physician who suffered from deep infiltrative endometriosis. I needed laparoscopic surgery, so I went to see my former gynaecologist and he performed the procedure (a surgery which he supposedly does hundreds of times a year) last November. I had severe pain again when I had my period in January and was advised to go on taking a low hormone dose anticoncipient pill. My symptoms came back quickly and got worse in a few months’ time. I went…
After years of excessively painful periods, a serious loss of quality of life, and a series of uninformed and uninterested doctors, Dr. Seckin and Dr. Goldstein turned my life around. I was told I woke up from my surgery almost a year ago with a smile on my face, and I haven't stopped since. Before I heard of Dr. Seckin, I was experiencing almost daily terrible pain to the point where I had difficulty walking, inability to eat, inexplicable weight…
Dr Seckin and his team gave me back my life! Tomorrow will be 1 month since my surgery and I feel great. Dr. Seckin, Dr Liu, and Dr Goldstein are not only beyond words talented and amazing Doctors, but they are also genuinely wonderful and caring people. I cannot say enough great things about Holly, Asiye and Kim as well. They were all caring, kind, patient, and took the time to listen to me and explain anything I needed to…
