Abstract:
To investigate the safety and feasibility of indocyanine green ( ICG ) fluorescence staining guided by laparoscopic ultrasound guiding portal branch puncture approach in anatomical segmentectomy of the liver . Methods The clinical data of 22 patients with malignant liver diseases underwent anatomical segmentectomy between February 2018 and M ay 2018 were retrospectively analyzed . ICG 0 .125～0 .250 mg was directly injected into the portal branches supplying blood flow to the tumor‐bearing hepatic segment , after puncturing of the target portal branch under intraoperative laparoscopic ultrasound guidance in all patients . T he fluorescence imaging system ( Pinpoint) was used for the resection procedure . Observation indicators :intraoperative conditions ( tumor diameter ,success rate of portal branches puncture ,success rate of staining the target hepatic segment ,intraoperative complications , time of operation ,volume of intraoperative blood loss , blood transfusion , and transit of laparotomy ) . Postoperative conditions :postoperative complications ,and length of hospital stay . Results Twenty‐two patients with liver tumors were all performed anatomical hepatectomy assisted by laparoscopic ultrasound guiding ICG injection for liver segment staining . All the liver tumors were hepatocellular carcinoma . ①Intraoperative conditions : T he portal branches puncture successful rate was 100% ( 22/22 ) . Eighteen patients achieved expected effect of ICG fluorescence staining ,with a satisfaction rate of 81 .8% (18/22) and 4 failed to get expected effect ,including 2 with uneven dying ,and 2 with adjacent hepatic segmental staining induced to unclear boundary . No complication such as allergy occurred in all patients after ICG injection . T he mean operation time was ( 209 ± 89 ) min ( range :97 ～ 325 min) and the target portal branches ICG puncture injection time under intraoperative laparoscopic ultrasound guidance was ( 11 ± 5) min ( range 3－25 min) . T here was no intraoperative blood transfusion or transit of laparotomy .Average tumor diameter was ( 3 .9 ± 1 .3) cm( range :2 .2－7 .0 cm ) . ②Postoperative conditions of 22 patients ,4 with grade Ⅰ － Ⅱ of Clavien‐Dindo classification were improved by drug treatments ( 1 with deep venous thrombosis of the lower extremities and 3 with pleural effusion ) , no patient had grade Ⅲ and above complications , and no perioperative death occurred . Average duration of hospital stay was ( 7 ± 2 ) days in 22 patients ( range :5 .0－14 .0 days) . Conclusions ICG fluorescence staining guided by laparoscopic ultrasound guiding portal branch puncture ,obtains accurate and lasting fluorescence markers on the liver surface and inside the parenchyma . ICG staining guides the selection of liver section in the operation of liver in real time ,and helps surgeons to perform laparoscopic anatomical segmentectomy of the liver .
