Curative resection of hepatocellular carcinoma using modified Glissonean pedicle transection versus the Pringle maneuver: a case control study

Anatomical sectionectomy based on Takasaki's segmentation for solitary intrahepatic cholangiocarcinoma: a propensity-matched analysis

BACKGROUND

Anatomical sectionectomy based on Takasaki's segmentation has shown advantages in hepatocellular carcinoma. However, whether this approach improves the survival of intrahepatic cholangiocarcinoma (ICC) remains unknown.

METHODS

A series of 248 consecutive patients with solitary ICCs who underwent hepatectomy were studied retrospectively. The patients were classified into the groups of anatomical sectionectomy based on Takasaki's segmentation (TS group) and non-Takasaki's hepatectomy (NTH group). The bias between the two groups was minimized using propensity score matching (PSM). Recurrence-free survival (RFS) and overall survival (OS) were evaluated with Kaplan-Meier analysis. The Cox proportional hazards model was performed to determine the adverse risk factors associated with survival.

RESULTS

After PSM, 67 pairs of patients were compared. Both the RFS and OS rates in the TS group were significantly better than those in the NTH group (23.2 % vs. 16.5 %, and 40.4 % vs. 27.3 %, P = 0.035 and 0.032, respectively). Multivariate analysis showed that NTH was independently associated with worse RFS and OS than TS. The stratified analysis demonstrated that the RFS and OS rates in the TS group with tumor stage I and tumor size ≥3 cm were significantly better than those in the NTH group, while the survival rates for ICC with stage I and tumor size <3 cm or stage II-III showed no significant difference.

CONCLUSION

TS was associated with improved RFS and OS in patients with solitary ICC even after PSM. TS may be preferred particularly in patients with tumor stage I and tumor size ≥3 cm.

The Application of Selective Hepatic Inflow Vascular Occlusion with Anterior Approach in Liver Resection: Effectiveness in Managing Major Complications and Long-Term Survival

BACKGROUND

Hepatectomy is always a challenge to surgeons and requires an appropriate approach for specific tumors to achieve effective complication management. Selective hepatic pedicle clamping is more considerable strategy when comparing with total hepatic pedicle clamping in the balance between reducing blood loss and transfusion with causing the hepatic parenchyma damages (two main complications affecting liver resection result).

OBJECTIVES

In this study, we aim to describe the application of selective hepatic inflow vascular occlusion (SHIVO) and anatomical anterior approach in liver resection and evaluate the results, focusing on intraoperative and postoperative complications.

METHODS

We enrolled 72 patients who underwent liver resection with SHIVO at Viet Duc University Hospital in 4-year period (2011-2014) and then followed up all of them until June 2020 (in 52.6 ± 33 months; range, 2-105 months) or up to the time of death. All the patients were diagnosed with primary or secondary liver cancer, and their future remnant liver volume measured on 64-slice CT scan (dm3) to body weight (kg) > 0.8% (for right hepatectomy). Perioperative parameters were collected and analyzed.

RESULTS

The average operation time was 196.2 ± 62.2 minutes, and blood loss was 261.4 ± 202.9 ml; total blood transfusion proportion during and after surgery was 16.7%. Complications accounted for 44.5% of patients in which pleural effusion was the most common one (41.7%). There were no liver failure and biliary fistula after surgery. No deaths were recorded during 30 days postoperatively. Average hospital stay was 11.4 ± 3.7 days. Blood transfusions during the operation and major liver resection were the factors significantly affecting the percentage of complications after liver surgery in our study. In the last follow-up evaluation, 44 patients were dead and 28 patients were alive, in which 7 with recurrence and 21 without recurrence. The overall survival rate was 38.9%.

CONCLUSION

SHIVO in anatomical liver resection is a safe and feasible approach to help resect precisely targeted tumors and manage several complications in liver resection.

Influence of the Glissonean Pedicle Transection Approach in Spiegel Lobe-Preserving Left Hepatectomy on Spiegel Lobe Volume and Remnant Liver Functions

BACKGROUND

The extrahepatic surgical technique in liver resection can be divided into glissonean pedicle transection and glissonean separated transection approaches. In this study, we compared remnant liver function and liver regeneration involving the Spiegel lobe between these two approaches regarding Spiegel lobe-preserving left hepatectomy.

METHODS

We enrolled 31 patients who underwent Spiegel lobe-preserving left hepatectomy for malignant hepatobiliary diseases between April 2008 and January 2020. The postoperative Spiegel lobe volume was measured using a volume analyzer at 3 and 6 months postoperatively.

RESULTS

Of the 31 patients, 22 and 9 were included in the glissonean separated transection and glissonean pedicle transection groups, respectively. There was no significant between-group difference in the preoperative Spiegel lobe volume. However, the volumes at 3 and 6 months postoperatively were significantly larger in the glissonean pedicle transection group than in the glissonean transection group (29.92 mL vs. 13.00 mL; P < 0.001 and 28.43 mL vs. 15.01 mL; P < 0.001, respectively). There was no significant between-group difference in postoperative remnant liver function.

CONCLUSIONS

The postoperative Spiegel lobe volume was larger, and liver regeneration was better with the glissonean pedicle transection approach because of transection for Spiegel branch of the portal vein. It is desirable to preserve Spiegel branch in possible cases when surgeons select the glissonean separated transection approach based on the location and size of the tumors.

Updates and Critical Insights on Glissonian Approach in Liver Surgery

Recent advances in surgical techniques have broadened the indications of surgical management of liver malignancies. Intraoperative bleeding is one of the known predictors of postoperative outcomes following liver surgery, signifying the importance of vascular control during liver resection. Furthermore, preservation of future liver remnant plays a critical role in prevention of post-hepatectomy liver failure as one of the main causes of postoperative morbidity and mortality. Glissonian approach liver resection offers an effective method for vascular inflow control while protecting future liver remnant from ischemia-reperfusion injury. Several studies have demonstrated the feasibility of Glisson's pedicle resection technique in modern liver surgery with an acceptable safety profile. Moreover, with increasing popularity of minimally invasive surgery, laparoscopic liver resection via Glissonian approach has been shown to be superior to standard laparoscopic hepatectomy. Herein, we systematically review the role of Glissonian approach hepatectomy in current practice of liver surgery, highlighting its advantages and disadvantaged over other methods of vascular control.

Impact of Glissonean pedicle approach for centrally located hepatocellular carcinoma in mongolia

Approaches to surgical resection of centrally located HCC remain controversial. Traditionally, hemi- or extended hepatectomy is suggested. However, it carries a high risk of postoperative complications in patients with cirrhosis. An alternative approach is Glissonean pedicle transection method. This study was conducted to assess the surgical and survival outcomes associated with central liver resection using the Glissonean pedicle transection. Sixty-nine patients with centrally located HCC were studied retrospectively. They were divided into conventional approach group with hemi- or extended hepatectomy, and Glissonean approach group with multisegmental central liver resection using the Glissonean pedicle transection. Glissonean pedicle transection method has comparable or superior surgical and survival outcomes to conventional hemi- or extended hepatectomy with regard to intraoperative bleeding, complications, hospital stay, and postoperative mortality and survival outcomes in patients with centrally located HCC. The 1-, 3-, and 5-year overall survival rates of the conventional approach group were 74%, 64%, and 55% respectively. For the Glissonean approach group, the 1 and 3-year overall survival rates were 86% and 61%, respectively. Glissonean pedicle transection method is a safe and effective surgical procedure in patients with centrally located HCC.
