Perioperative outcome of laparoscopic left lateral liver resection is improved by using staple line reinforcement technique: a case report.
Current laparoscopic stapling technology still cannot prevent bile leakage (<55%) along the resection margin. A new staple line reinforcement technique was used in the present case. This technique incorporates an absorbable polymer membrane into the stapler system, such that it buttresses the transected solid organ. The objectives of this novel procedure are to decrease hemorrhage at the staple line and to prevent bile duct leakage after liver resection. A 47-year-old man followed for status post biliopancreatic diversion with duodenal switch presented with epigastric pain. On imaging, he was found to have a lesion in segment 2-3 of the left lobe of the liver, which measured at least 3 cm in diameter. He was admitted to the hospital to undergo a laparoscopic left lateral liver resection. This procedure involved laparoscopic ultrasonography of the liver and transection of the left liver lobe with endoscopic linear staplers. The staple height of 3.5, 60 mm long, reinforced with an absorbable polymer membrane was used for liver transection to catch the portal branches. This required multiple firings in the liver parenchyma and additional division of some tissue using the Harmonic scalpel. The larger branch in the middle of segment 2-3 and the left hepatic vein were both transected with the novel staple line reinforcement technique. Bleeding or any bile leakage in this area could not be visualized. No drains were left. The patient's postoperative course was uncomplicated, and he was discharged on postoperative day 3. Pathology results showed a cavernous hemangioma of 4.5 cm in diameter. Staple line reinforcement with the absorbable polymer membrane has the potential to decrease staple line hemorrhage and bile leakage.
