Object: With the gradual advancement of laparoscopic technology, surgeries can be successfully performed with the help of laparoscopy increasingly. This study initially explored the difference between laparoscopic right posterior sectionectomy (LRPS) and open right posterior sectionectomy (ORPS)of liver in our center, discussed the effectiveness, benefits and safety of LRPS and introduce some surgical techniques in our center. Materials and methods: We retrospectively analyze 96 cases of liver tumor located in the right posterior lobe of liver in our institution from January 2015 to January 2018. There were 46 cases performed the LRPS surgery and 50 cases performed the ORPS surgery. Through analysis of the perioperative outcomes of these two groups by a case control study, we compare the differences between these two groups. Results: There was no significant difference between the LRPS and ORPS group in demographic and baseline characteristics before surgery. Patients in the LRPS group were significantly superior to ORPS in terms of postoperative liver function recovery, postoperative inflammatory factor level, pain sensation (3.03 ± 0.79 vs 4.58 ± 1.25), abdominal incision length (6.25 ± 2.34 vs 32.15 ± 3.21), carrying abdominal drainage tube time (3.26 ± 0.77 vs 4.83 ± 0.76), recovery of bowel function time (1.6 ± 0.61 VS 3.05 ± 0.85)and postoperative hospital stay (5.73 ± 0.99 vs 7.16 ± 0.95) (P

Compared with the traditional ORPS, LRPS has the advantages of minor injury, faster recovery and mild inflammatory reaction. The LRPS is safe and feasible, and it should be gradually promoted in clinical practice. [ABSTRACT FROM AUTHOR]

Background: Laparoscopic right posterior sectionectomy is technically challenging secondary to poor exposure of the surgical field and difficulty with controlling hemorrhage during deeper parenchymal transection Cho et al., Surgery 158:135-141, 2015; Lee et al., Surgery 160:1219-1226, 2016. We present laparoscopic right posterior sectionectomy using the Glissonean approach and a modified liver hanging maneuver.Methods: A 57-year-old man presented with a single mass in segment 7 of the liver. He was placed in the lithotomy position, and five trocars were used in the upper abdomen. The hepatoduodenal ligament was encircled using an umbilical tape to perform the intermittent Pringle maneuver. After detachment of the hilar plate, the right posterior Glissonean pedicle was dissected and clamped to confirm ischemic delineation Takasaki, J Hepato-Biliary-Pancreat Surg 5:286-291, 1998. After complete mobilization of the right liver, the hanging tape was placed along the inferior vena cava between the caval ligament and the right hepatic vein. The hanging tape elevates the liver and guides the surgeon to achieve an accurate transection plane Belghiti et al., J Am Coll Surg 193:109-111, 2001; Kim et al., Surg Endosc 30:3611-3617, 2016; Kim, Choi, J Gastrointest Surg 21:1181-1185, 2017; Kim et al., Langenbecks Arch Surg 403:131-135, 2018 . The transection plane used during a right posterior sectionectomy is horizontal and follows the inferior vena cava. However, with the liver hanging maneuver, the horizontal transection plane becomes vertical.Result: The operation time was 290 min, the estimated blood loss was 120 mL, and the total Pringle maneuver time was 60 min. Final histopathological diagnosis showed a 1.7-cm-sized hepatocellular carcinoma with the resection margin measuring 1.5 cm. The patient was discharged on postoperative day 7 without any complications.Conclusion: A Glissonean approach with a modified liver hanging maneuver is feasible and useful for laparoscopic right posterior sectionectomy.
