## Contribution

This case highlights a rare instance of a silent retained needle in the abdominal cavity post-surgery.

## Key findings

- A corroded needle was found in the mesentery of the ascending colon after laparoscopic cholecystectomy.
- The needle was successfully removed during laparotomy without causing acute inflammation.
- The case emphasizes the importance of thorough postoperative monitoring for foreign bodies.

## Abstract

A plethora of reports have previously been published concerning the removal of intra-abdominal foreign bodies. However, in most of these cases, an acute inflammatory reaction occurred. In emergency medicine, accidental sewing needle ingestion is a frequent presentation. However, it is extremely uncommon for the needle to be inserted through the abdominal wall and remain silent inside the abdominal cavity. We hereby report a case of incidental finding of a needle retrieved from the antimesenteric intestinal border of the ascending colon in a 41-year-old female patient who presented to our hospital with acute right abdominal colic on the third postoperative day after laparoscopic cholecystectomy. Laparotomy was performed, and the corroded needle was successfully removed from the mesentery together with its sheath.
