Dorsal Approach Combined with In Situ Split for Laparoscopic Segment 7 Resection.

Background: Laparoscopic segment 7 resection has been a technically challenging procedure (Li et al. in J Gastrointest Surg 23:1084-1085, 2019). We introduce a dorsal approach with in situ split for laparoscopic segment 7 resection.

Clinical impact and role of major vessels involvement in laparoscopic resection for hepatic hemangioma.

Background: Severe bleeding remains a significant concern in laparoscopic resection for hepatic hemangioma. It is rarely reported that how the degree of major vessels involvement impacts on severe bleeding. The present study primarily aimed to analyze the impacts of the number of involved major vessels (NIMV) during laparoscopic surgery for hepatic hemangioma and evaluate the risk factors associated with increased bleeding.

Caudodorsal approach combined with in situ split for laparoscopic right posterior sectionectomy.

Background: Laparoscopic right posterior sectionectomy (LRPS) was technically challenging and lack of standardization. There were some approaches for LRPS, such as caudal approach and dorsal approach. During our practice, we initiated pure LRPS using the caudodorsal approach with in situ split and present several advantages of this method.

Effects of retrograde reperfusion on the intraoperative internal environment and hemodynamics in classic orthotopic liver transplantation.

Background: To investigate the effects of retrograde reperfusion on the intraoperative internal environment and hemodynamics in classic orthotopic liver transplantation (OLT).

Methods: Thirty patients were undergone classic OLT using retrograde reperfusion in our center. Blood sampling was done at different time points including: Before blood venting via the portal vein (PV), 10 mL of blood was collected from the inferior vena cava (T); During retrograde reperfusion through the inferior vena cava (IVC), 10 mL of blood was collected when the volume of blood venting reached 10 mL (T), 100 mL (T), and 200 mL (T), respectively.
