Extrahepatic Glissonean approach for laparoscopic major liver resection (with video)

Indocyanine green fluorescence image-guided laparoscopic anatomical S2/3 resection using the TICGL technique

BACKGROUND

Segment 2/3 (S2/3) resection, which can preserve more residual liver parenchyma, is a feasible alternative to left lateral sectionectomy. However, it is still challenging to perform anatomical S2/3 resection safely and precisely, especially laparoscopically. This study was designed to evaluate the safety and accuracy of the temporary inflow control of the Glissonean pedicle (TICGL) technique combined with indocyanine green (ICG) fluorescence imaging in laparoscopic anatomical S2/3 resection.

PATIENTS AND METHODS

A total of 12 patients recruited at Zhujiang Hospital of Southern Medical University from June 2021 to August 2022 were included in the study. All patients underwent ICG fluorescence imaging guided laparoscopic anatomical S2/3 resection. The TICGL technique was used to control the blood inflow of the target segment. The total time used to control the hepatic inflow of the target segment, the time of hemostasis, the amount of intraoperative blood loss, predicted resected liver volume (PRLV) and actual resected liver volume (ARLV) were used to evaluate the simplicity, safety, and accuracy of the TICGL technique combined ICG fluorescent imaging in guiding laparoscopic anatomical S2/3 resection.

RESULTS

Of the 12 included patients, 7 underwent S2 resection and 5 underwent S3 resection. The operation time was 76.92 ± 11.95 min, the intraoperative blood loss was 15.42 ± 5.82 ml, and the time of hepatic blood inflow control was 7.42 ± 2.43 min. There was a strong correlation between PRLV and ARLV (r = 0.903, P < 0.05).

CONCLUSION

The combination of the TICGL technique with ICG negative staining fluorescence imaging is a feasible approach for laparoscopic anatomical S2/3 resection.

"Liver parenchyma dissecting-first" method facilitates the Glissonean pedicle approach in anatomical laparoscopic hepatolobectomy

Background

Anatomical laparoscopic hepatolobectomy (ALH) is a difficult and challenging operation, and avoiding massive hemorrhage during parenchyma transection remains one of its major concern. Glissonean pedicle approach (GPA) has achieved great success in open liver surgery due to its simplicity and reproducibility, but it is difficult to apply in ALH for the limited vision and motion. We thus aimed to introduce a modified method to facilitate the GPA in ALH.

Methods

In this retrospective study, in 15 patients who underwent ALH (at least 2 couinaud segments), the liver parenchyma was dissected at first (LPDF) adequately under intermittent total inflow control to reveal the Glissonean pedicle (GP) sufficiently for safe and precise transection. The technical details of LPDF for different types of hepatolobectomy and a modified laparoscopic Pringle maneuver are described, and the surgical outcomes are reviewed.

Results

LPDF was applied in all patients, and intraoperative blood transfusion was not needed. LPDF facilitated GPA in ALH without any severe morbidity or mortality.

Conclusions

LPDF is a safe and effective technique, it reduces the difficulties in inflow occlusion in GPA and can promote the application of ALH. Further clinical control trails are needed to validate the superiority of LPDF compared with GPA in ALH.

Laparoscopic Anatomic Spiegel Lobectomy With the Extrahepatic Glissonean Approach

BACKGROUND

Laparoscopic Spiegel lobectomy is difficult due to its deep location and being surrounded by gross vessels. Extrahepatic Glissonean pedicle transection method has been proposed by Takasaki during open liver resections. This approach can be successfully performed during laparoscopic anatomic hepatectomy. Here we describe pure laparoscopic Spiegel lobectomy using the extrahepatic Glissonean approach.

METHODS

The patient was a 25-year-old male with a background of hepatitis B. A 1.5 cm×1.7 cm mass was detected in liver Spiegel lobe and highly suspected to be an hepatocellular carcinoma. The liver function was normal (Child-pugh 5), and alpha-fetoprotein was within the normal ranges. Laparoscopic Spiegel lobectomy using extrahepatic Glissonean approach was proposed. The hilar plate was partly detached from liver parenchyma, and 2 Glissonean pedicles of the Spiegel lobe were dissected, clamped and divided. Liver parenchymal transection was performed using the harmonic scalpel.

RESULTS

The operation time was 196 minutes without Pringle's maneuver. Estimated blood loss was <50 mL, and no blood transfusion was required. The patient recovered well and was discharged on postoperative day 6. There was no complication. Pathologic findings support the diagnosis of hepatocellular carcinoma.

CONCLUSIONS

Laparoscopic Spiegel lobectomy using the extrahepatic Glissonean approach is safe and feasible.

Useful maneuvers for precise laparoscopic liver resection

Laparoscopic liver resection has evolved over the past decade and nearly replaced open exploration. This procedure not only provides comparable oncological outcomes, but it also has improved recovery after surgery. Many of the challenges presented by limitations of instruments and techniques have been overcome through adaptations and new developments, and it is possible that the remaining obstacles will be overcome within a few years. Moreover, as surgeons continue to gain experience, their technical knowledge has supported further improvement in minimally invasive approaches. This review examines every important procedures in performing a precise laparoscopic liver resection.

Totally laparoscopic associating liver partition and portal vein ligation for staged hepatectomy using anterior approach in HCC patient with Type II portal vein anomaly: a case report

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has gradually developed because of rapid hypertrophy of the future liver remnant volume (FLR) in spite of high morbidity. To minimize the patient's postoperative pain and morbidity including wound complication caused by two consecutive major abdominal operations, we adopted a totally laparoscopic approach and used a composite mesh graft. Also, to maximize the oncologic efficacy, we adopted the “anterior approach” technique. A 44-year-old woman with large hepatitis B-related hepatocellular carcinoma (HCC) in her right lobe was transferred to our hospital for surgical treatment. Preoperatively predicted FLR by a CT scan was 21% and type II portal vein anomaly was detected. A totally laparoscopic approach was planned. During the first stage operation, right anterior and posterior portal veins were meticulously dissected and tied. After parenchymal transection by the “anterior approach” technique, two glissonian pedicles of the right liver were individually isolated. A composite mesh graft was used to prevent severe adhesion on both liver partition surfaces. During the second-stage operation, 9 days after the first stage operation, the two isolated glissonian pedicles were initially transected. After full mobilization of the right lobe, the right hepatic vein was also transected. The right lobe was removed through the Pfannenstiel incision. She was discharged 7 days after the second stage operation. Her postoperative course was uneventful and there was no HCC recurrence for 15 months after hepatectomy. A totally laparoscopic ALPPS procedure can be a feasible technique that ensures patient safety and oncologic superiority, even in patients with complicated anatomical variation.

Evolution of laparoscopic surgery in a high volume hepatobiliary unit: 150 consecutive pure laparoscopic hepatectomies

INTRODUCTION

Compared to other surgical areas, laparoscopic liver resection (LLR) has not been widely implemented and currently less than 20% of hepatectomies are performed laparoscopically worldwide. The aim of our study was to evaluate the feasibility, and the ratio of implementation of LLR in our department.

METHODS

We analyzed a prospectively maintained database of 749 liver resections performed during the last 10-year period in a single centre.

RESULTS

A total of 150 (20%) consecutive pure LLR were performed between 2005 and 2015. In 87% of patients the indication was the presence ofprimary or metastatic liver malignancy. We performed 30 major hepatectomies (20%) and (80%) were minor resections, performed in all liver segments. Twelve patients were operated twice and 2 patients underwent a third LLR. The proportion of LLR increased from 12% in 2011 to 62% in the last year. Conversion rate was 9%. Overall morbidity rate was 36% but only one third were classified as severe. The 90-day mortality rate was 1%. Median hospital stay was 4 days and the rate of readmissions was 6%.

CONCLUSIONS

The implementation of LLR has been fast with morbidity and mortality comparable to other published series. In the last 2 years more than half of the hepatectomies are performed laparoscopically in our centre.

Application of temporary inflow control of the Glissonean pedicle method provides a safe and easy technique for totally laparoscopic hemihepatectomy by Glissonean approach

The Glissonian approach, due to its simplicity of procedure, is a technical procedure widely used in open hepatectomy. However, it is not easily applicable in the setting of the total laparoscopic approach because of movement restriction. We herein propose a new and simple method of performing hemihepatectomy by Glissonian approach called temporary inflow control of the Glissonian pedicle (TICGL) technique. Dissection of the Glisson pedicle from the liver parenchyma is done until the posterior margin of the pedicle is visualized, and is clamped with bulldog clamps. Encircling the pedicle is not necessary. Resection of the liver parenchyma is performed under inflow control of the resected side liver providing less bleeding. After sufficient resection is done so that the whole Glissonian pedicle structures are visualized, the pedicle is encircled, often very easily without the fear of bleeding from the posterior side of the pedicle, which is a common problem when encircling is done before parenchymal resection. The staplers may then be applied safely without injuring the major hepatic veins since they have been already exposed. Stapling is done while the tape is retracted toward the contralateral side. This retraction prevents injury or stricture of the contralateral Glissonian pedicle branch. The remnant liver parenchyma is resected and hepatectomy finalized. The TICGL technique provides a safe and easy way of performing major hemihepatectomies, not only by expert laparoscopic surgeons but by less experienced surgeons. It can therefore become a standard method of performing hemihepatectomy by Glissonian approach.

Robotic extrahepatic Glissonean pedicle approach for anatomic liver resection in the right liver: techniques and perioperative outcomes

BACKGROUND

The Glissonean pedicle approach is one of the most popular methods of anatomic liver surgery. Liver surgeons have attempted to reproduce this method laparoscopically. In this study, we introduce our technique of the extrahepatic Glissonean approach for anatomic liver resections, using a robotic system, and report on short-term perioperative outcomes.

METHODS

From December 2008 to July 2014, 10 patients underwent robotic anatomic liver resection in the right liver. The procedure is as follows: (1) mobilization of the liver and isolation and clamping of a selected Glissonean pedicle; (2) transection of the liver parenchyma using a rubber band retraction technique; (3) division of the Glissonean pedicle after full exposure, followed by completion of parenchymal transection.

RESULTS

The median age of the patients was 52.50 (range 28-59) years, and seven were male. All patients had hepatocellular carcinoma. The types of resections performed were as follows: segmentectomy 6 (n = 1), segmentectomy of 4b + 5 ventral segments (n = 2), right posterior sectionectomy (n = 3), extended right hepatectomy (n = 1), extended right posterior sectionectomy (n = 2), and central bisectionectomy (n = 1). Only one case was converted to open surgery due to severe tumor adhesions on the diaphragm. The median operative time was 555 min (range 413-848), and the median estimated blood loss was 225 ml (range 30-700), with no perioperative transfusions. The overall complication rate was 70 % (grade I, 5; grade II, 1; grade III, 1; grade IV, 0). The median length of hospital stay postsurgery was 7 days (range 6-11).

CONCLUSION

Robotic surgery allowed for successful anatomic liver resections via an extrahepatic Glissonean pedicle approach in the right liver and can be safely performed in selected patients.

Laparoscopic liver resection: 5-year experience at a single center

Background

Hepatocellular carcinoma (HCC) is a common cancer, especially in the Association of Southeast Asian Nations (ASEAN) region, where the prevalence of hepatitis virus infection is high. Liver resection is a potentially curative and popular therapy for HCC. Laparoscopic surgery using minimally invasive techniques potentially brings benefits to patients who need liver resection for HCC. This study aimed to evaluate the effectiveness, safety, and benefits of laparoscopic liver resection for HCC with long-term follow-up evaluation.

Methods

This cohort study with 5-year results of total laparoscopic hepatectomy for HCC was conducted in one center. Patients with HCC were selected for laparoscopic liver resection by the same team. The operation also was performed by one team of surgeons. The follow-up protocol was similar to that for open surgery. The patients were scheduled to return for examination every 2 months after the operation. The data for the patients were collected and analyzed using SPSS software.

Results

From January 2008 to December 2012, 173 enrolled patients with HCC underwent laparoscopic liver resection. The male-to-female ratio was 3:1. The mean age of the patients was 56 years (range 16–83 years). The follow-up period for 130 patients was 21.6 ± 16.0 months (range 0–60 months). The mean tumor size was 3.73 cm (range 2–10 cm). The stages of HCC according to the Barcelona Clinic Liver Cancer (BCLC) categorization were as follows: 0 (6 %), A1 (59.5 %), A2 (6.9 %), A4 (2.9 %), and B (27.2 %). Four patients required conversion to other techniques (2.3 %) because of the potential for major bleeding and tumor perforation. The types of resection were resection of one segment (segments 2, 3, 4, 5, 6, 7, and 8; 43.8 %), resection of two segments (posterior sector, anterior sector, segments 5 and 6, and left lateral sector; 47.9 %), resection of three segments (left and central liver; 4.7 %), and four segments (right liver; 3.6 %). The mean operation time was 112 ± 56 min (range 30–345 min), and the median blood loss was 100 ml (range 20–1,200 ml). The mean hospital stay was 6.5 ± 2.0 days (range, 3–19 days). No perioperative mortality occurred. The overall survival rates were 94.2 % at 1 year, 87 % at 2 years, 72.9 % at 3 years, 72.9 % at 4 years, and 72.9 % at 5 years. The mean overall survival time was 49.7 ± 2.1 months (range 45.5–53.9 months). The disease-free survival rates were 79.1 % at 1 year, 60 % at 2 years, 57 % at 3 years, 52 % at 4 years, and 26.3 % at 5 years. The mean disease-free survival time was 38.9 ± 2.6 months (range 33.9–44.0 months).

Conclusion

Laparoscopic liver resection for HCC is feasible, safe, and effective, with good oncologic results. Major and anatomic hepatectomy are possible with improved skill and experience. Laparoscopic liver resection is a promising treatment option with minimally invasive benefits for HCC patients.
