The topic at hand is about preparing for an end-ostomy reversal, which is a procedure to reconnect the bowel after having an ostomy. The person scheduled for this surgery is concerned about the lack of a bowel prep and antibiotics before the operation, as they fear potential complications like stool leakage during the reconnection.

Here are some insights and advice shared by others who have gone through similar procedures:

1. Many people have had ileostomy or colostomy reversals without any mechanical bowel prep, just following the instruction of nothing by mouth (NPO) after midnight. Some were allowed small sips of water until the surgery.

2. Others were advised to follow a clear-liquid diet or to take a full bowel prep with laxatives the day before surgery. One person mentioned their upcoming colostomy reversal includes bowel prep but no antibiotics.

3. The approach can vary depending on the surgeon and the type of stoma being closed:
- Colostomy closures might benefit from a "Nichols prep," which involves a standard colonoscopy laxative prep plus oral antibiotics like neomycin and erythromycin. Alternatives may be used if neomycin is unavailable, as this method can reduce the risk of leaks.
- Ileostomy closures, or cases where the patient no longer has a colon, often skip bowel prep.

4. During the surgery, certain measures help prevent contamination. Anesthesia can reduce bowel movement, the bowel ends are clamped and cleaned before being sewn together, and some surgeons use a nasogastric (NG) tube after surgery to keep the intestines still while healing.

5. It's important to reach out to the surgeon’s office for clarification on pre-op instructions. Asking questions is encouraged, as understanding the process is crucial for your peace of mind.

6. After the surgery, here’s what to expect and how to care for yourself:
- Diarrhea, frequent bowel movements, and acidic output are common. Protect your skin with petroleum jelly and be ready for a long adjustment period.
- Initially, you might experience bowel movements 10–15 times a day, especially if the reconnection is low in the rectum.
- Recovery from major abdominal surgery can take up to a year, particularly for those over 30. Be patient and ease back into normal activities gradually.
- Some people find it helpful to wear incontinence pads or Depends during the early months to manage any accidents.
