Painful anal drop after minimally invasive surgery for appendicitis may be due to constipation and anal fissure due to weakened bowel movement after surgery, and pelvic effusion due to appendicitis surgery. Appendiceal surgery may lead to weakened peristalsis due to irritation of the gastrointestinal tract, causing the patient to experience postoperative constipation and anal fissure. Patients may be concerned about the presence of blood in the stool, which requires an improved diet, the use of corkscrew for laxation if necessary, and the use of hemorrhoidal suppositories or hemorrhoidal ointment to alleviate the clinical symptoms if the crushing pain is significant. The appendix is in a low position and may be inflamed, leading to pelvic fluid formation and cramping pain. This is treated with oral or intravenous antibiotics such as cefepime, ciprofloxacin and metronidazole. If you have anal falling and pain after minimally invasive surgery for appendicitis, you should communicate with your attending physician in time.
