Current Status of Laparoscopic Liver Resection

The evolution of laparoscopic liver surgery, originating in the 1990s, has been marked by significant advancements and milestones, overcoming initial technical hurdles and gaining widespread acceptance within the surgical community as a precise and safe alternative to open procedures. Along this journey, numerous challenges emerged, leading to the accumulation of evidence and the development of guidelines aimed at assisting surgeons in determining the safety, suitability, and complexity of laparoscopic liver resection. This chapter provides a thorough examination of key aspects of laparoscopic liver resection, including difficulty scoring systems, criteria for patient selection, technical considerations, outcomes across different types of liver lesions, and the innovative solutions developed to address challenges, thus offering a comprehensive overview of laparoscopic liver resection, and highlighting its evolving significance in modern hepatobiliary surgery.

Single-port endoscopic-sentinel lymph node biopsy combined with indocyanine green and carbon nanoparticles in breast cancer

BACKGROUND

In order to explore the surgical safety and the reliability of axillary staging of single-port endoscopic-sentinel lymph node biopsy, we combined it with indocyanine green that was excited by near-infrared fluorescence endoscopy and carbon nanoparticles as a tracer and compared this method to conventional open sentinel lymph node biopsy.

METHODS

This is a retrospective and observational study, there were 20 patients in each group and the total sample size was 60: Group 1, single-port endoscopic-sentinel lymph node biopsy combined with indocyanine green and carbon nanoparticles; Group 2, single-port endoscopic-sentinel lymph node biopsy with carbon nanoparticles only; Group 3, conventional sentinel lymph node biopsy with indocyanine green and carbon nanoparticles. Sentinel lymph node detection and upper extremity function were determined to measure the safety and efficacy of the novel single-port endoscopic-sentinel lymph node biopsy (SPE-SLNB) technique to the standard conventional sentinel lymph node biopsy technique.

RESULTS

The detection rate of sentinel lymph nodes was 100% in Group 1, 100% in Group 2, and 95% in Group 3. There were no significant differences in upper arm function and pain scores between the three groups.

CONCLUSION

The novel technique of combining indocyanine green and carbon nanoparticles with single-port endoscopic-sentinel lymph node biopsy achieved a similar detection rate and mean number of sentinel lymph nodes as conventional sentinel lymph node biopsy. Traditional open surgery requires two different incisions for breast surgery and SLNB. While the most important advantage of SPE-SLNB is that two procedures can be effectively performed through a single-port in the axilla Therefore, for patients who meet the indications, single-port endoscopic-sentinel lymph node biopsy is as safe and reliable as conventional sentinel lymph node biopsy but has the aesthetic advantage of only one incision.

Laparoscopic versus open surgery for hepatic caudate lobectomy: a retrospective study

BACKGROUND

This study was designed to investigate the feasibility and safety of laparoscopic hepatic caudate lobectomy (LHCL) for treating liver tumor by comparing with the open hepatic caudate lobectomy (OHCL).

METHODS

In the LHCL group, we included 24 patients with liver tumor received LHCL in Qilu Hospital of the Shandong University from January 2014 to January 2019. Meanwhile, 24 matched liver tumor patients underwent OHCL in our hospital served as control. Then we compared the patient characteristics, intraoperative parameters, and postoperative outcomes between LHCL group and OHCL group.

RESULTS

There were no significant differences in gender, age, degree of cirrhosis, tumor size, preoperative liver function, Child-Pugh grading, proportion of liver cirrhosis, and tumor size between LHCL group and OHCL group (P > 0.05). No death was reported in both groups. The length of incision in LHCL group was significantly lower than that in OHCL group (4.22 ± 1.14 cm vs. 22.46 ± 4.40 cm, P < 0.001). The intraoperative blood loss in LHCL group was significantly lower than that of OHCL group (116.82 ± 71.61 ml vs. 371.74 ± 579.35 ml, P = 0.047). The total operation time, Pringle maneuver occlusion time, and blocking rate in LHCL group showed no statistical difference compared with those of the OHCL group (P > 0.05). The VAS scores at postoperative 24 and 48 h showed no statistical differences between LHCL group and OHCL group (P > 0.05). Compared with the OHCL group, significant decrease was noticed in the proportion of patients with severe pain 48 h after surgery (0 vs. 4.25 ± 0.46, P < 0.001) and dezocine consumption (90.45 ± 45.77 mg vs. 131.6 ± 81.30 mg, P = 0.0448) in the LHCL group.

CONCLUSION

LHCL is effective and feasible for treating liver tumor, which is featured by reducing intraoperative blood loss and serious pain.

Liver abscess in the caudate lobe caused by a fishbone and treated by laparoscopy: a case report

Background

Ingestion of fish bones leading to gastric perforation and inducing abscess formation in the caudate lobe of the liver is very rare.

Case presentation

A 67-year-old man presented to our hospital with a 2-day history of subxiphoid pain. There were no specific symptoms other than pain. Laboratory tests showed only an increase in the number and percentage of neutrophils. Contrast-enhanced Computerized tomography (CT) of the abdomen showed two linear dense opacities in the gastric cardia, one of which penetrated the stomach and was adjacent to the caudate lobe of the liver, with inflammatory changes in the caudate lobe. We finally diagnosed his condition as a caudate lobe abscess secondary to intestinal perforation caused by a fishbone based on the history and imaging findings. The patient underwent 3D laparoscopic partial caudate lobectomy, incision and drainage of the liver abscess, and fishbone removal. The procedure was successful and we removed the fishbone from the liver. The patient was discharged on the 9th postoperative day without other complications.

Conclusions

Liver abscess caused by foreign bodies requires multidisciplinary treatment. Especially when located in the caudate lobe, we must detect and remove the cause of the abscess as early as possible. Foreign bodies that perforate the gastrointestinal tract can penetrate to the liver and cause abscess formation, as in this case. When exploring the etiology of liver abscesses, we should investigate the general condition, including the whole gastrointestinal tract.

Laparoscopic caudate lobectomy: a multicenter, propensity score-matched report of safety, feasibility, and early outcomes

BACKGROUND

Caudate lobectomy via laparoscopic surgery has rarely been described. This multicenter, propensity score-matched study was performed to assess the safety and efficacy of laparoscopic caudate lobectomy (LCL).

METHODS

A multicenter retrospective study was performed including all patients who underwent LCL and open caudate lobectomy (OCL) in four institutions from January 2013 to December 2018. In total, 131 patients were included in this study and divided into LCL (n = 19) and OCL (n = 112) groups. LCLs were matched to OCLs (1:2) using a propensity score matching (PSM) based on nine preoperative variables, including patient demographics and tumor characteristics. The pathological results, perioperative and postoperative parameters, and short-term outcomes were compared between the two groups.

RESULTS

After PSM, there were 18 and 36 patients in the LCL and OCL groups, respectively. Baseline characteristics were comparable after matching. LCL was associated with less blood (100 vs. 300 ml, respectively; P < 0.001) and a shorter postoperative stay (6.0 vs 8.0 days, respectively; P = 0.003). Most patients' resection margins were > 10 mm in the LCL group (P = 0.021), and all patients with malignancy in both groups achieved R0 resection. In terms of early postoperative outcomes, the overall morbidity rate was identical in each group (11.1% vs. 11.1%, respectively; P = 1.000). No mortality occurred in either group.

CONCLUSIONS

Laparoscopy is a feasible choice for resection of tumors located in the caudate lobe with acceptable perioperative results.

Feasibility of laparoscopic isolated caudate lobe resection for rare hepatic mesenchymal neoplasms

BACKGROUND

Mesenchymal tumors such as perivascular epithelioid cell neoplasm (PEComa) and inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDC sarcoma) are relatively uncommon in the liver and are particularly rare in the caudate lobe. The clinical manifestations and available imaging tests lack specificity for hepatic mesenchymal tumors. To the best of our knowledge, no caudate PEComa or IPT-like FDC sarcoma has been completely resected by laparoscopy. The standard laparoscopic technique, surgical approaches, and tumor margins for potentially malignant or malignant caudate mesenchymal tumors are still being explored.

AIM

To assess both the safety and feasibility of laparoscopic resection for rare caudate mesenchymal neoplasms.

METHODS

Eleven patients who underwent isolated caudate lobe resection from 2003 to 2017 were identified from a prospective database. Three consecutive patients with rare caudate mesenchymal tumors underwent laparoscopic resection. Patient demographic data, intraoperative parameters, and postoperative outcomes were assessed and compared with the open surgery group.

RESULTS

All procedures for the three resection patients with caudate mesenchymal tumors were completed using a total laparoscopic technique by two different approaches. The average operative time was 226 min, and the estimated blood loss was 133 mL. The average length of postoperative hospital stay was 6.3 ± 0.3 d for the laparoscopy group and 15.5 ± 2.3 d for the open surgery group (P < 0.05). There were no perioperative complications or patient deaths in this series.

CONCLUSION

Laparoscopic isolated caudate lobe resection for rare mesenchymal neoplasms is a feasible and curative surgical option in selected patients.

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.

Laparoscopic caudate lobe resection for the treatment of hepatolithiasis

Background

To explore the safety and feasibility of laparoscopic caudate lobe (CL) resection for the treatment of hepatolithiasis.

Methods

A retrospective study of nine patients who received laparoscopic CL resection for treatment of hepatolithiasis in our hospital from January 2013 to April 2017. Of these cases, we studied the patients' demographic data, the operation time, blood loss, post-operative hospital stay, post-operative complications and prognosis.

Results

All the nine cases are performed successfully; the post-operative recovery was symptom free except for one case of post-operative bile leakage. Among them, there were six cases of CL resection in combination with other lobe, three cases of separate CL resection, and three cases of whole CL resection. The average operative time was 310 min (Range: 180-450 min), the average intraoperative blood loss was 530 ml (Range: 100-1000 ml), average post-operative hospital stay was 9 days (Range: 6-13 days), average total hospital stay was 10 days (Range: 9-19 days). Intraoperative calculi exhaustion rate was 66.7% (6/9), which at the end of treatment was 88.9% (8/9). No cases had calculi recurrence.

Conclusion

The application of laparoscopic CL resection is feasible and safe.

Robot-assisted laparoscopic partial hepatic caudate lobectomy

Background: Hepatic caudate lobectomy is considered to be a technically difficult surgery because of the unique anatomy and deep location of the hepatic caudate lobe. Here, we assessed the technical feasibility and safety of robotic partial caudate lobectomy using the da Vinci^® Surgical System and compared it with traditional open/laparoscopic surgery.Material and methods: Six patients diagnosed with liver cancer (primary liver cancer, 5; metastasis of breast cancer, 1) who underwent caudate lobectomy were prospectively enrolled. Two patients underwent robotic surgery, one underwent laparoscopic surgery, and three underwent traditional/open surgery. Surgical procedure, recovery, and characteristics of robotic surgery were noted and compared with other approaches.Results: All surgeries were successfully completed, and no serious postsurgical complications were observed. In the robotic group, the time taken to complete the surgery and the estimated intraoperative bleeding were 150 and 90 min and 50 and 100 ml in patient 1 and patient 2, respectively. The patients were able to tolerate fluid diet on the following postsurgical day. These two patients had no postsurgical complications and were discharged from the hospital on days 5 and 6 after recovery, respectively. Pathologically, the margins of specimens obtained from these two patients were tumor-free (R0 resection). Tumor size in the traditional/open group was larger than that in the robotic and laparoscopic groups. Blood loss in the laparoscopic case was 50 ml and was less than that in the traditional/open surgery cases (300, 2100, and 1500 ml).Conclusions: Robot-assisted partial hepatic caudate lobectomy is a technically feasible surgery. Our study illustrated an advantage of robotic hepatic caudate lobectomy over laparoscopic or traditional/open surgery and suggested that da Vinci^® minimally invasive hepatectomy is applicable in even more technically challenging anatomic locations.

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.

Laparoscopic Total Caudate Lobectomy for Hepatocellular Carcinoma

BACKGROUND

Caudate lobe is located in the deep dorsal area of the liver between the portal triad and the inferior vena cava (IVC). Torrential bleeding can occur from the IVC and short hepatic veins during dissection. Isolated total caudate lobe resection is still rare and technically demanding. We herein present a video on the technical aspect of laparoscopic total caudate lobectomy.

METHOD

A 61-year-old woman was admitted for recurrent hepatocellular carcinoma detected on imaging. She had history of multifocal hepatocellular carcinoma in July 2015 and underwent open cholecystectomy, segment 6 and segment 8 tumorectomy. Ten months later, the computed tomography scan and magnetic resonance imaging showed a 1 cm arterial enhancing lesion in segment I (S1) with no other foci of recurrence. Laparoscopic total caudate lobectomy was contemplated.

RESULTS

The operative time was 270 minutes. The intraoperative blood loss was 200 mL and blood transfusion was not necessary. The patient was discharged on the fourth postoperative day without any complications.

CONCLUSION

This report showed the safety and feasibility of laparoscopic total caudate lobectomy. Nonetheless, it is a technically demanding procedure. It should be performed in carefully selected patients and by experienced hepatobiliary surgeons proficient in laparoscopic liver resection.

A South Indian Cadaveric Study About the Relationship of Hepatic Segment of Inferior Vena Cava with the Liver

INTRODUCTION

Inferior Vena Cava (IVC) is the largest vein of the body. It runs vertically upwards in the abdomen, behind the liver. Its course is very constant in relation to liver. However, the amount of liver parenchyma related to it can vary from person to person. The data regarding its course and relations may be very useful to radiologists and surgeons during surgical treatment procedures for Budd-Chiari syndrome, liver carcinoma, liver transplant, venous cannulations and many other clinical procedures.

AIM

Aim of this study was to document the incidence of straight and curved course of IVC in relation to liver and also to note the pattern in which the liver tissue was related to the IVC.

MATERIALS AND METHODS

In the current study, 95 adult cadaveric livers were observed; specifically to study the course/direction of the hepatic segment of IVC in relation to the liver. The extent of liver tissue related to various aspects of IVC was also studied. The course of the IVC was classified as straight and curved; and the relationship of liver parenchyma to the IVC was classified into 6 categories. The data was expressed as percentage incidence.

RESULTS

In 78.94% cases, the IVC had a straight course in relation to the liver; whereas in 21.06% cases, it had a left sided curve (concavity of the curve towards the caudate lobe) in its course. In 6.31% cases, IVC travelled in a tunnel, being encircled by the liver parenchyma all around; in 36.84% cases, it was covered by liver parenchyma on front and sides so that only posterior surface of IVC was visible; in 3.15% cases it was covered by liver tissue on front, sides and also partly on posterior aspect; in 50.52% of cases, its anterior surface, sides and left edge of the posterior surface was covered by liver tissue; and in 3.15% cases it was covered only from the front by the liver tissue.

CONCLUSION

The data being reported here might be useful for surgeons while planning and executing various hepatic surgeries and also to the radiologists in planning and performing venous cannulation and therapeutic procedures. Since in many livers, the curvature of IVC was associated with enlarged caudate lobe, the curved IVC could hint about the increase in the volume of caudate lobe or liver itself.

Surgical Techniques for Totally Laparoscopic Caudate Lobectomy

OBJECTIVES

The purpose of this study is to identify the safety and feasibility of laparoscopic caudate lobectomy.

BACKGROUND

Caudate lobectomy has been considered as technically difficult because of the deep location of the caudate lobe and its proximity to great vessels. Due to the technical difficulty, laparoscopic caudate lobectomy was not feasible in patients with malignancy in the caudate lobe.

METHODS

Six consecutive patients with caudate hepatic malignancy received laparoscopic caudate lobectomy at Samsung Medical Center from September 2007 to May 2014. Demographic data, intraoperative parameters, and postoperative outcomes were assessed.

RESULTS

All procedures for these 6 patients with caudate malignancy were completed with totally laparoscopic technique. Only 1 patient who had hepatocellular carcinoma in the Spiegel lobe underwent partial caudate lobectomy, and others underwent complete caudate lobectomy. The mean tumor size was 2.65 cm (range 0.9-5.1 cm). The mean operative time was 382 minutes (range 168-615 minutes) and none required transfusion. The mean duration of hospital stay was 8 days (range 6-13 days). There was no perioperative complication and patient mortality in this series. The resected margins of the specimens were tumor free (R0 resections, range 0.1-1.2 cm). The mean follow-up period was 56 months (range 12.9-93.7 months). No patient died during the follow-up period.

CONCLUSIONS

Our experience demonstrated that laparoscopic caudate lobectomy is safe and feasible in selected patients with malignancy in the caudate lobe.

Laparoscopic liver resection: Experience based guidelines

Laparoscopic liver resection (LLR) has been progressively developed along the past two decades. Despite initial skepticism, improved operative results made laparoscopic approach incorporated to surgical practice and operations increased in frequency and complexity. Evidence supporting LLR comes from case-series, comparative studies and meta-analysis. Despite lack of level 1 evidence, the body of literature is stronger and existing data confirms the safety, feasibility and benefits of laparoscopic approach when compared to open resection. Indications for LLR do not differ from those for open surgery. They include benign and malignant (both primary and metastatic) tumors and living donor liver harvesting. Currently, resection of lesions located on anterolateral segments and left lateral sectionectomy are performed systematically by laparoscopy in hepatobiliary specialized centers. Resection of lesions located on posterosuperior segments (1, 4a, 7, 8) and major liver resections were shown to be feasible but remain technically demanding procedures, which should be reserved to experienced surgeons. Hand-assisted and laparoscopy-assisted procedures appeared to increase the indications of minimally invasive liver surgery and are useful strategies applied to difficult and major resections. LLR proved to be safe for malignant lesions and offers some short-term advantages over open resection. Oncological results including resection margin status and long-term survival were not inferior to open resection. At present, surgical community expects high quality studies to base the already perceived better outcomes achieved by laparoscopy in major centers’ practice. Continuous surgical training, as well as new technologies should augment the application of laparoscopic liver surgery. Future applicability of new technologies such as robot assistance and image-guided surgery is still under investigation.

A Left-Sided, Purely Laparoscopic Approach for Anatomic Caudate Hepatectomy: A Single-Center Experience

BACKGROUND

Laparoscopic caudate hepatectomy, which is a challenging procedure, has been reported sporadically. However, there is no standardized surgical technique, and the safety and feasibility of this procedure remain controversial.

MATERIALS AND METHODS

A left-sided, purely laparoscopic approach for anatomic caudate hepatectomy was used for 11 selected patients in our institution. The procedure and technique of laparoscopic caudate hepatectomy were described. Perioperative data of these patients were retrospectively reviewed.

RESULTS

The 11 cases included two subgroups: laparoscopic isolated caudate hepatectomy (n = 4) and laparoscopic combined caudate and left hemihepatectomy (n = 7). There were three major steps for anatomic caudate hepatectomy. Two conversions were required (18.2%). Two complications (Clavien Grades I and II) occurred but no deaths.

CONCLUSIONS

The left-sided, purely laparoscopic approach for anatomic caudate hepatectomy is safe and feasible in selected patients. This procedure can be performed by hepatobiliary surgeons with abundant experience in laparoscopic liver surgery.

Learning curve in laparoscopic liver surgery: a fellow's perspective

The learning curve for laparoscopic liver surgery is infrequently addressed in current literature. In this paper, we explored the challenges faced in embarking on laparoscopic liver surgery in a unit that did predominantly open liver surgery. In setting up our laparoscopic liver surgery program, we adopted skills and practices learnt during fellowships at various high volume centers in North America and Australia, with modifications to suit our local patients' disease patterns. We started with simple minor resections in anterolateral segments to build confidence, which allowed us to train the surgical and nursing team before progressing to more difficult resections. Inter institutional collaboration and exchange of skills also enabled the synergistic development of techniques for safe progression to more complex surgeries. Multimedia resources and international guidelines for laparoscopic liver surgery are increasingly accessible, which further guide the practice of this emerging field, as evidence continues to validate the laparoscopic approach in well selected cases.

Totally robotic isolated caudate-lobe liver resection for hydatid disease: report of a case

BACKGROUND

Hepatic caudatectomy has always been considered a challenging procedure, because of the complex anatomy and deep location of this segment. Herein we report the first case of a totally robotic isolated caudate-lobe liver resection ever performed for hydatid disease.

METHODS

A 55 year-old man was referred to our institution after diagnosis was made of a 5.6 cm hepatic lesion of the caudate lobe. Radiological suspicion was for hydatid disease. The patient underwent robotic-assisted hepatic caudatectomy.

RESULTS

The operative time was 280 min and the estimated blood loss was 200 ml. The postoperative course was uneventful. The drain was removed on post-operative day 3 and the patient was discharged on post-operative day 6.

CONCLUSION

Robotic resection of the caudate lobe is a technically feasible procedure, which nevertheless requires high hepato-pancreato-biliary surgery skills, both in open an mini-invasive approaches. It provides several technical advantages in the field of mini-invasive surgery, yet assuring patient safety. Copyright © 2015 John Wiley & Sons, Ltd.
