Background and Objectives: In laparoscopic liver resections, tumor localization is a critical aspect of ensuring clear resection margins and preserving the hepatic parenchyma. In this study, we designed a fluorescence imaging technique using a new fluorophore for tumor localization. Materials and Methods: Immediately before laparoscopic or transthoracic liver resection, microcatheter was inserted through the hepatic artery and used to engrave the segment containing the tumor in the intervention room. Under blue light, the fluorescence of the lesion was visually confirmed, and the location was determined through intraoperative sonography. After tumor localization, liver resection was performed. Results: From February 2017 to March 2020, 24 patients underwent laparoscopic liver resection (LLR) or video-assisted transthoracic liver resection (VTLR) using intervention-guided fluorescence imaging technique (IFIT). Conclusions: IFIT can provide some advantages in the field of LLR. In addition, in cases of VTLR for hepatocellular carcinoma in the superior posterior segment in patients with marginal liver function, IFIT is considered useful.

AbstractDiaphragmatic resection may be required beneath the diaphragm in some patients with liver tumors. Laparoscopic diaphragmatic resection is technically difficult to secure in the surgical field and in suturing. We report a case of successful laparoscopic hepatectomy with diaphragmatic resection. A 48-year-old man who underwent laparoscopic partial hepatectomy for liver metastasis of rectal cancer 20 months ago underwent surgery because of a new hepatic lesion that invaded the diaphragm. The patient was placed in the left hemilateral decubitus position. The liver and diaphragm attachment areas were encircled using hanging tape. Liver resection preceded diaphragmatic resection with the hanging tape in place. Two snake retractors were used to secure the surgical field for the inflow of CO2 into the pleural space after diaphragmatic resection. The defective part of the diaphragm was repaired using continuous or interrupted sutures. Both ends of the suture were tied with an absorbable suture clip without ligation. In laparoscopic liver resection with diaphragmatic resection, the range of diaphragmatic resection can be minimized by performing liver resection using the hanging method before diaphragmatic resection. The surgical field can be secured using snake retractors. Suturing with an absorbable suture clip is conveniently feasible.
