Laparoscopic right posterior sectionectomy for a large hepatocellular carcinoma close to inferior vena cava.

ABSTRACT: Approximately 20% of hepatocellular carcinomas (HCC) occur in noncirrhotic livers. Resection may be considered for patients with HCC, provided sufficient future liver remnant is available, regardless of the tumor size. Tumors located posteriorly near the right hepatic vein (RHV), or inferior vena cava can be managed through anterior or caudal approaches. RHV is typically conserved during right posterior sectionectomy. When a large posteriorly placed tumor causes chronic compression on RHV, the right anterior section drainage is redirected preferentially to the middle hepatic vein. The division of RHV in such instances does not cause congestion of segments 8 and 5. The technical complexity of laparoscopic right posterior sectionectomy arises from the large transection surface, positioned horizontally. We describe in this multimedia article, a case of large HCC in segments 6 and 7, which was successfully treated using laparoscopic anatomic right posterior sectionectomy.

Project description:BackgroundLaparoscopic 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.MethodsFrom April 2018 to December 2021, consecutive patients who underwent pure LRPS using the caudodorsal approach with in situ split at our institution entered into this retrospective study. The key point of the caudodorsal approach was that the right hepatic vein was exposed from peripheral branches toward the root and the parenchyma was transected from the dorsal side to ventral side. Specially, the right perihepatic ligaments were not divided to keep the right liver in situ before parenchymal dissection for each case.Results11 patients underwent pure LRPS using the caudodorsal approach with in situ split. There were 9 hepatocellular carcinoma, 1 sarcomatoid hepatocellular carcinoma, and 1 hepatic hemangioma. Five patients had mild cirrhosis and 1 had moderate cirrhosis. All the procedures were successfully completed laparoscopically. The median operative time was 375 min (range of 290-505 min) and the median blood loss was 300 ml (range of 100-1000 ml). Five patients received perioperative blood transfusion, of which 1 patient received autologous blood transfusion and 2 patients received blood transfusion due to preoperative moderate anemia. No procedure was converted to open surgery. Two patients who suffered from postoperative complications, improved after conservative treatments. The median postoperative stay was 11 days (range of 7-25 days). No postoperative bleeding, hepatic failure, and mortality occurred.ConclusionThe preliminary clinical effect of the caudodorsal approach with in situ split for LRPS was satisfactory. Our method was feasible and expected to provide ideas for the standardization of LRPS. Further researches are required due to some limitations of this study.

Project description:BackgroundAlthough laparoscopic liver resection has become the standard for minor resections, evidence is lacking for more complex resections such as the right posterior sectionectomy (RPS). We aimed to compare surgical outcomes between laparoscopic (LRPS) and open right posterior sectionectomy (ORPS).MethodsAn international multicenter retrospective study comparing patients undergoing LRPS or ORPS (January 2007-December 2018) was performed. Patients were matched based on propensity scores in a 1:1 ratio. Primary endpoint was major complication rate defined as Accordion ≥ 3 grade. Secondary endpoints included blood loss, length of hospital stay (LOS) and resection status. A sensitivity analysis was done excluding the first 10 LRPS patients of each center to correct for the learning curve. Additionally, possible risk factors were explored for operative time, blood loss and LOS.ResultsOverall, 399 patients were included from 9 centers from 6 European countries of which 150 LRPS could be matched to 150 ORPS. LRPS was associated with a shorter operative time [235 (195-285) vs. 247 min (195-315) p = 0.004], less blood loss [260 (188-400) vs. 400 mL (280-550) p = 0.009] and a shorter LOS [5 (4-7) vs. 8 days (6-10), p = 0.002]. Major complication rate [n = 8 (5.3%) vs. n = 9 (6.0%) p = 1.00] and R0 resection rate [144 (96.0%) vs. 141 (94.0%), p = 0.607] did not differ between LRPS and ORPS, respectively. The sensitivity analysis showed similar findings in the previous mentioned outcomes. In multivariable regression analysis blood loss was significantly associated with the open approach, higher ASA classification and malignancy as diagnosis. For LOS this was the open approach and a malignancy.ConclusionThis international multicenter propensity score-matched study showed an advantage in favor of LRPS in selected patients as compared to ORPS in terms of operative time, blood loss and LOS without differences in major complications and R0 resection rate.
