Diagnostic laparoscopy.

A 10 mm laparoscope was inserted under the ETN after processing the operating field through the umbilical ring. CO insufflation 2 . During the audit: in the small pelvis and between the loops of the small intestine, traces of lysed blood are drained. In the right iliac fossa, a loose infiltrate is determined, consisting of the dome of the cecum and the appendix, the latter destructively changed and fixed to the parietal peritoneum. The infiltrate is divided, the appendix is ​​isolated to the base. The mesentery was dissected using bipolar coagulation. At the base of the appendix, 3 Raeder loops are tightened. The appendix is ​​cut off, immersed in a container, removed. Sanitation of the abdominal cavity. Control of hemostasis - dry. A drainage tube is installed in the small pelvis, brought out through an incision above the bosom. Stitches for wounds. Aseptic dressings.
