Video-assisted thoracoscopic surgery is becoming more popular in thoracic surgery practice. Use of endostaplers is mandatory for anatomical video-assisted thoracoscopic surgery resections. In this article, we present an unusual complication related to use of endostapler, which, to our knowledge, may be the first reported in the literature.

Video-assisted thoracosopic surgery (VATS) has become popular in thoracic surgery practice.[1] Compared to lobectomy via thoracotomy, VATS lobectomy may cause less postoperative pain, shorter chest tube duration, shorter length of hospital stay, lower morbidity, and may even improve survival in patients with early-stage non-small cell lung cancer.[2] Bronchial stapling was first reported in the 1960s.[3] As staplers became more sophisticated, their use has been widely accepted and regarded as a safe procedure. [4] Although VATS is supported by the frequent use of staplers, only a few papers have been published concerning stapling failure or adverse events.[5-7] In this article, we present an unusual complication related to use of endostapler, which, to our knowledge, may be the first reported in the literature.

Case Presentation

A 61-year-old male patient was diagnosed as adenocarcinoma of lung located in the left lower lobe. The preoperative mediastinal and distant metastatic staging evaluation revealed cT2N0M0 disease, while so surgical resection was planned. We performed uniportal VATS left lower lobectomy in our standardized fashion using a single 4 cm incision performed at the fourth intercostal space. Just after the inferior pulmonary vein closure using vascular stapler, the vein nearly totally dehisced with considerable amount of bleeding (>500 mL). The area of the vessel where bleeding occurred was repaired with 4/0 polypropylene running sutures with the help of atraumatic thoracoscopic clamp. The rest of the surgery was uneventful and the resection was completed. The formal counting for surgical instruments and gauzes were approved by the table and circulating nurse before closure. The patient was transferred to the clinic postoperatively and had a posteroanterior chest X-ray as he arrived to his bed as our routine early follow-up. In the evaluation of the X-ray, there was a suspicious metallic object located in the left hemithorax (Figure 1a). In the primary check, nothing was found in the outer surface of the hemithorax. The metallic shape and size of the object was new and unknown for us. We ordered an urgent computed tomography and the metallic object was noted on the scans (Figure 1b). A 2-cm metallic part of one of the endostapling devices was found to be missing on careful examination of used stapler-loads (Figure 2). The patient was informed about the situation and he agreed to undergo surgery again to remove the object. There was a short session of explorative uniportal VATS using the same incision. The object was located at posterior hemithorax covered with a small hematoma (Figure 3a). It was removed from the pleural space easily (Figure 3b). The postoperative period was uneventful and the patient was discharged on the third day of the second surgery. The patient has been doing well without any problem for 15 months. A written informed consent was obtained from the patient.

Despite standardized use of endoscopic staplers that are accepted as safe devices, some unexpected incidents may occur.[5-7] Understanding the safety issues and possible problems regarding the use of endoscopic devices is of utmost importance. We successfully managed two stapling device problems that occurred in the same patient. First problem was a totally opened lower pulmonary vein that was successfully repaired, while the second was the dislocation of a metallic element of the stapler. The metallic piece was removed using the same (uniportal) approach. The stapling device was regular, undamaged, and used for the first time. This broken metallic part which fell into the pleural space was confirmed to be fixed to the body of the device. This information was approved by the manufacturer and the device was delivered to them for further technical investigation. According to the literature and the manufacturer's feedback, such a complication had never been reported. After falling into the pleural space, the object may have been either hidden in a distal point of the cavity and moved to its place during repositioning the patient in operating room or covered with a small clot which hid it on the thoracic wall.

Explorative visualization as well as counting surgical instruments and gauzes are routinely performed before closure in each VATS as a surgical principle. Methodologies including Six Sigma that strive to achieve perfect quality[8] may be adopted as a quality principle for surgeries to prevent such structural problems.[8,9]

This case should remind us about the importance of double-checking the integrity of the used stapling devices during surgery. All team members in the operating room including the circulating nurse should be aware of the necessity to check such details to prevent any event that may require an additional surgery.
