How long after a laposcopic surgery will you know if you have bowel perforation?

Yes: Bowel perforations are typically painful, not subtle. Constipation after laparoscopic surgery is normal. However, if you have any question see your surgeon or contact your surgeon.

Soon: Fortunately, this is an uncommon complication, but it can be life threatening and usually manifests in 3-5 days after operation. This timeframe is typical, but there are always exceptions. Hope this helps, and i hope there is no perforation.

A few days: Rarely a cautery burn will show up later.

Usually in days : If a perforation happens, a known complication of laparoscopic surgery, the size of the opening will regulate how much bowel content may leak. Location in small (lq) or large bowel (solid) affects likely leakage. Small holes may quickly seal up and cause no problem. Leaks that are larger will typically cause peritoneal inflammation (peritonitis) and usually be noticed within a few days (2-3).
