Needle lost in minimally invasive surgery: management proposal and literature review

The reported incidence of intraoperative retained instruments, such as needles, hangs around 0.06–0.11%. Leaving a needle inside the abdominal cavity can have significant medical and legal consequences. In addition, the retrieval can be hampered due to the limited visualization of the scope during minimally invasive surgery. Factors associated with an increased probability for NL have been described. Prevention for this situation includes: having one needle at a time inside the cavity, effective communication between all personnel in the operating room, evaluation of the strength of the suture–needle connection, avoid parking of needles intraoperatively, and a proper needle withdrawal. Notwithstanding, no agreement has been made regarding NL management. Herein, we present a literature review, and a management proposal in which through a series of systematic steps, the surgical team can efficiently locate and retrieve a lost needle such as: examination of the surgical field, trocar visualization, trocar disassembly, and revision of the suction device. Finally, intraoperative or postoperative imaging can be utilized.
