# Isolated Cystic Duct Injury Caused by a Gunshot Wound: A Case Report of an Extremely Rare Finding

## TL;DR

A rare case of a gunshot wound causing only a cystic duct injury is reported, highlighting the importance of recognizing such uncommon trauma.

## Contribution

This case report presents an extremely rare instance of isolated cystic duct injury without other associated injuries.

## Key findings

- Isolated cystic duct injury can occur from a gunshot wound without other biliary or organ injuries.
- Successful treatment was achieved through cholecystectomy with satisfactory recovery.
- Such injuries are often overlooked due to their rarity and subtle symptoms.

## Abstract

Extrahepatic biliary tree injuries are uncommon, but isolated extrahepatic biliary tree injuries are extremely rare and are usually associated with other injuries. The most common associated injuries include liver, spleen, and/or duodenal injuries. Due to their rarity and generally insidious onset of symptoms, extrahepatic biliary tree injuries are often overlooked during the initial trauma evaluation, which can lead to significant associated morbidity. Their management, considering hemodynamic stability and imaging findings, includes nonoperative and surgical management, which may include minimally invasive (laparoscopy), open surgery, and/or endoscopy. We present the case of a 28-year-old male patient admitted with a gunshot wound to the abdomen. Surgical findings included a laceration of the cystic duct, with no associated injuries. A cholecystectomy is performed. Following surgery, the patient made satisfactory postoperative progress and was subsequently discharged.
