Background: Tourniquet for right hepatectomy tightened and secured with forceps (arrow). Laparoscopic liver resection is performed worldwide. Hemorrhage is a major complication and bleeding control during hepatotomy is an important concern. Pringle maneuver remains the standard inflow occlusion technique., Aim: Describe an extracorporeal, efficient, fast, cheap and reproducible way to execute the Pringle maneuver in laparoscopic surgery, using a chest tube., Methods: From January 2014 to March 2020, our team performed 398 hepatectomies, 63 by laparoscopy. We systematically encircle the hepatoduodenal ligament and prepare a tourniquet to perform Pringle maneuver. In laparoscopy, we use a 24 Fr chest tube, which is inserted in the abdominal cavity through a small incision. We thread the cotton tape through the tube, pulling it out through the external end, outside the abdomen. To perform the tourniquet, we just need to push the tube as we hold the tape, clamping both with one forceps., Results: The 24 Fr chest tube is firm and works perfectly to occlude blood inflow as the cotton band is tightened. It has an internal diameter of 5,5 mm, sufficient for a laparoscopic grasper pass through it to catch the cotton band, and an external diameter of 8 mm, which allows to be inserted in the abdomen through a tiny incision. The cost of this tube and the cotton band is less than US$ 1. No complications related to the method were identified in our patients., Conclusions: The extracorporeal Pringle maneuver presented here is a safe, cheap and reproducible method, that can be used for bleeding control in laparoscopic liver surgery.

Background: Portal vein embolization is an accepted procedure that provides hypertrophy of the future remnant liver in order to reduce post-hepatectomy complications., Aim: To present a series submitted to portal vein embolization using an adapted hysterosalpingography catheter via transileocolic route., Methods: Were performed right portal branch embolization in 19 patients using hysterosalpingography catheter. For embolizing the vessel, was used Gelfoam(r) powder with absolute alcohol solution. Indications for hepatectomy were colorectal liver metastases in all cases., Results: An adequate growth of the future remnant liver was achieved in 15 patients (78.9%) and second time hepatectomy could be done in 14 (73.7%). In one patient (5.2%), tumor progression prevented surgery. One patient presented acute renal failure after portal embolization., Conclusions: The hysterosalpingography catheter is easy to handle and can be introduced into the portal vein with a wire guide. There were no major post-embolization complication. Its use is safe, cheap and effective.

Background: The worldwide rising demand for cadaveric donors in liver transplantation is an important incentive for the development of alternative transplantation options, such as living donors. A precise evaluation of surgical complications is, therefore, considered to be an important issue in this setting., Aim: Present a retrospective analysis of 126 living donors hepatectomies undertaken at our centre., Methods: From December 2002 to August 2009, 126 living donors were submitted to hepatectomy. Donors' complications were stratified according to Clavien's scoring system to compare the morbidity of right hepatectomy (RH) (Group 1) and left lateral sectionectomy (LLS) (Group 2)., Results: Thirty-nine complications were observed in 35 patients. Sixty LLS, 3 left (LH) and 63 RH were performed. The complications were classified as: Clavien grade 1-11 (28.2%), grade 2-12 (30.7%), grade 3A-13 (33.3%), grade 3B-2 (5.1%) and grade 4A-1 (2.5%). When Group 1 (63 patients) and Group 2 (60 patients) were compared, there was no significant difference between the number of complications: 20 (31%) and 14 (23%), respectively (P > 0.3)., Conclusions: Hepatectomy for living donor liver transplantation (LDLT) was a safe procedure, regardless of the type of liver resection undertaken. We found no difference in morbidity between RH and LLS, which suggests that complications may occur despite the amount of liver retrieved.

Anatomical resection of segment VIII (SVIII) is one of the most difficult hepatectomies to perform. Although it is the best choice of surgical treatment for tumors located at SVIII, its feasibility can be compromised when the right hepatic vein (RHV) must be resected en bloc with SVIII. Herein we describe a case of a cirrhotic patient that was submitted to segmentectomy VIII in bloc with themain trunk of the RHV, due to hepatocellular carcinoma. The resection could only be performed because a well developed inferior right hepatic vein (IRHV) was present. Anatomical variations of the liver vascularization should be used by liver surgeons to improve surgical results. [ABSTRACT FROM AUTHOR]
