Postoperative pain around the navel after ovarian cancer surgery may be related to factors such as incomplete wound healing after surgery and local infection. Ovarian cancer surgery may be performed by laparoscopic perforation around the umbilicus, which may cause pain around the umbilicus when the incision is not completely healed after surgery. Some patients’ appendix may be located in the periumbilical area, which may damage the local nerves during the surgery, thus causing pain in the periumbilical area after surgery, which is a normal reaction and does not need special treatment, and the pain will disappear after the wound heals. If the local hygiene of the surgical opening is poor after ovarian cancer surgery, it may lead to infection of the surgical opening, and the local inflammation caused by infection will stimulate the periumbilical tissues to produce pain symptoms, accompanied by local redness, swelling, oozing and suppuration. At this time, local or systemic anti-infection treatment is needed. If pain around umbilicus is found after ovarian cancer surgery, one should consult doctor in time and take treatment under doctor’s guidance, and should not take medication without authorization in order to avoid delaying the condition. Pay attention to rest on weekdays and avoid overwork.
