Despite improvements in the safety of surgical procedures, leaving a foreign object in a patient’s body is still one of the complications of surgical procedures. The literature lacks an analysis of the effectiveness of specific diagnostic tests in detecting foreign objects. The authors present a discussion of the effectiveness of selected techniques and examples of the appearance of foreign bodies in radiological images based on the description of 10 cases. Leaving surgical haemostatic material in the abdominal or pelvic cavity is an underestimated phenomenon that poses a serious diagnostic problem. Computed tomography is the most sensitive method for detecting a foreign body, while a chest or abdominal X-ray is the simplest and most effective way to identify the surgical material. Ultrasound, although widely available, has not shown utility in diagnosing foreign bodies in our cases. Awareness of this problem is necessary to avoid unnecessary mortality in surgical patients.

The authors present seven cases of surgical drape left in body cavities during surgical operations. The most common symptoms reported by these patients are analysed and the consequences of leaving a foreign body in the abdominal cavity are summarised. In the majority of cases, the time elapsed from the operation to the detection of the foreign body was an average of 17 months. In one case, the foreign body remained in the abdomen for 7 years. The most common symptom reported by patients was abdominal pain. Some patients also developed wound healing disorders with leakage of pus from the wound, fever, nausea and vomiting, weight loss or intermittent tarry stools. In most cases, the foreign body required reoperation to remove it. Major surgery with stoma creation or bowel resection was required. In one case described, the consequence of leaving a surgical drape was the death of the patient. In three cases, there was spontaneous expulsion of the surgical sling by the patient by natural means.

Introduction: The management of wounds where the presence of a foreign body is possible can be a major problem. This is especially true for bodies that are not visible on x-ray. The most common of these are wood and glass. The size of the foreign body is also important. If even the smallest foreign body is left behind, it can cause permanent local tissue damage or contribute to a systemic infection such as sepsis or permanent local tissue damage. Foreign body recognition in one third of patients does not occur during primary provision. [1]The authors present four patients in whom a foreign body in the form of wood or glass was left in the wound after trauma. The diagnosis and removal of these foreign bodies caused many difficulties. The foreign bodies were not completely removed from the wounds after the injury, leading to an inflammatory process. The authors discuss the management of non-metallic foreign bodies in everyday medical practice.
