Laparoscopic Versus Open Appendectomy

Study Overview
=================
Brief Summary
-----------------
comparison between laparoscopic and open appendectomy in the management of chronic appendicitis

Detailed Description
-----------------
The appendix is a blind-ended tube connected to the cecum, from which it develops in the embryo. The most common diseases of the appendix (in humans) are appendicitis and carcinoid tumors. Appendicitis is inflammation of the appendix. Symptoms commonly include right lower abdominal pain, nausea, vomiting, and decreased appetite. However, approximately 40% of people do not have these typical symptoms . Appendicitis is caused by a blockage of the hollow portion of the appendix. This is most commonly due to a calcified stone made of feces. Inflamed lymphoid tissue from a viral infection, parasites, gallstone, or tumors may also cause the blockage. This blockage leads to increased pressures in the appendix, decreased blood flow to the tissues of the appendix, and bacterial growth inside the appendix causing inflammation. The combination of inflammation, reduced blood flow to the appendix and distention of the appendix causes tissue injury and tissue death. If this process is left untreated, the appendix may burst, releasing bacteria into the abdominal cavity, leading to increased complications. The surgical procedure for the removal of the appendix is called an appendicectomy. Appendicectomy can be performed through open or laparoscopic surgery. The surgical procedure for the removal of the appendix is called an appendicectomy . Appendicectomy can be performed through open or laparoscopic surgery. When the surgeon uses the open approach, he makes an incision in the lower right section of the abdomen. Most incisions are less than 3 in (7.6 cm) in length. The surgeon then identifies all of the organs in the abdomen and examines them for other disease or abnormalities. The appendix is located and brought up into the wounds. The surgeon separates the appendix from all the surrounding tissue and its attachment to the cecum, and then removes it. The site where the appendix was previously attached, the cecum, is closed and returned to the abdomen The muscle layers and then the skin are sewn together . When the surgeon performs a laparoscopic appendectomy, four incisions, each about 1 in (2.5 cm) in length, are made. One incision is near the umbilicus, or navel, and one is between the umbilicus and the pubis. Two other incisions are smaller and are on the right side of the lower abdomen. The surgeon then passes a camera and special instruments through these incisions. With the aid of this equipment, the surgeon visually examines the abdominal organs and identifies the appendix. The appendix is then freed from all of its attachments and removed. The place where the appendix was formerly attached, the cecum, is stitched. The appendix is removed through one of the incisions. The instruments are removed and then all of the incisions are closed . The primary objective of this study was to compare the laparoscopic approach and the conventional technique in the treatment of chronic Appendicitis.
