Robotics in hepatobiliary surgery-initial experience, first reported case series from India

Implementation of robotic and laparoscopic hepatopancreatobiliary surgery in low- and middle-income settings: a systematic review and meta-analysis

BACKGROUND

Despite numerous barriers, the application of minimally invasive surgery (MIS) for hepatopancreatobiliary (HPB) conditions has been increasing globally. This study aims to review the current status of HPB MIS in LMICs.

METHODS

Relevant databases were searched, identifying 3452 publications, 38 of which met the inclusion criteria. Meta-analysis of outcomes was carried out using "R" statistical software.

RESULTS

This study reviewed reports of application of MIS for HPB conditions in LMICs, analyzing a total of 3272 procedures. India (66.87 %) and Egypt (20.11 %) contributed majorly to the procedures reviewed. Others were from Indonesia (8.68 %), Colombia (3.06 %), Pakistan (0.67 %), Sri Lanka (0.34 %), Trinidad and Tobago (0.18 %), and Nigeria (0.09 %). India was the only LMIC with robotic HPB MIS. The majority of the procedures were biliary (74.88 %). Basic procedures accounted for 55.63 %, while 44.37 % were advanced. The overall conversion rate and prevalence of morbidity were 8 % [95 % CI: 5; 13], and 15 % [95 % CI: 9; 22], respectively. Robotics was associated with higher conversion (14 % vs 6 %, p < 0.01) but lower morbidity (10 % vs 16 %, p = 0.91), compared to laparoscopic surgery. There were 5 cases of mortality from laparoscopy.

CONCLUSION

The outcomes in this systematic review, compared to findings in other settings indicate successful implementation of HPB MIS in LMICs.

The Use of Robotics in Surgery of Benign Liver Diseases: A Systematic Review

BACKGROUND

Surgical treatment of benign liver diseases (BLD) remains a field of conflict, due to increased risk and high complication rate. However, the introduction of minimally invasive surgery has led to increased number of patients with BLD being treated surgically, with similar outcomes and fewer complications. Current data support the application of laparoscopic surgery (LS) and robotic surgery (RS) in surgical treatment of liver malignancies, but there are insufficient data concerning the application of robotic surgery in BLD. In the present systematic review, we aimed to evaluate the application of RS in BLD surgery.

METHODS

After a thorough search of Medline, Scopus, and Cochrane Library, 12 studies were considered eligible with a total number of 115 patients with BLD.

DISCUSSION

In brief, RS appears to be a safe and feasible option for BLD surgery. When compared to open surgery, RS is associated with lower blood loss, shorter length of stay, and fewer complication rate. Regarding LS, the peri- and postoperative outcomes were similar, but RS can overcome the technical limitations of LS. However, the cost of RS remains a major drawback in its widespread application.

CONCLUSIONS

Considering our findings, RS can be a safe and feasible option for BLD surgery, but further studies are needed to justify the introduction of RS in liver surgery and to define the type of patients that will benefit the most from it.

Robotic Biliary Surgery

Robotic cholecystectomy is safe and feasible approach and can be combined with common bile duct exploration to address complicated pathology in a single setting. This article summarizes reported outcomes after robotic biliary surgery. A technical overview of robotic multiport and single port cholecystectomy is provided. Last, the approach to benign bile duct disease during robotic cholecystectomy, including reconstruction of the biliary tree, is described.

Not just minor resections: robotic approach for cystic echinococcosis of the liver

INTRODUCTION

Human echinococcosis is among the 17 neglected tropical diseases recognized by the World Health Organization. It is responsible for over $3 billion of health costs every year being endemic in large areas worldwide, and liver is affected in 70% of the cases. Surgery associated to medical treatment is the gold standard and robotic approach may be a valuable tool to achieve safe, parenchyma sparing resections.

METHODS

We retrospectively analyzed the outcomes of patients that underwent robotic radical surgical treatment for hydatid liver disease, from prospectively maintained databases of three Italian centers.

RESULTS

15 patients were included in this study, median age 51 years (24-76). 1 right hepatectomy, 2 left lateral sectionectomies, 5 segmentectomies (including 1 caudatectomy), 3 wedge resections and 5 cyst-pericystectomies were performed. Median estimated blood loss was of 100 ml (50-550 ml), and median operative time including docking was 210 min (95-590 min), with no need for conversion to open. Median hospital stay was 4 days, with only one readmission for fever. Only one patient experienced recurrence in a different liver segment.

CONCLUSIONS

In our experience, robotic approach for cystic echinococcosis of the liver proved to be a safe and effective strategy also in the so-called "difficult segments", with short post-operative stay and quick return to daily activities, along with the absence of surgical site recurrences. To the best of our knowledge, this is the largest report of robotic approach to hydatid liver disease.

Reasons for open conversion in robotic liver surgery: A systematic review with pooled analysis of more than 1000 patients

BACKGROUND

Conversion to open during minimally invasive liver resection has a high rate. To identify the reasons to convert could help in defining a strategy to decrease the event "conversion."

METHODS

A systematic review has been performed. Our large series of robotic hepatic resections were analyzed and included in the review.

RESULTS

Fifty papers were selected and carefully evaluated in full text. Twenty-nine were ultimately used for analysis, including all published robotic liver resections. Our series included 11 conversions out of 139 patients (7.9%). Adhesions were not a declared reason to convert. The robotic approach still had a high percentage of open conversions because of difficulties in assessing the tumor margin.

CONCLUSIONS

Causes for conversion were carefully analyzed and compared with what previously described for the pure laparoscopic approach. This could be crucial in defining how to improve the performance and minimize the conversion rate.

Robotic surgery for gallbladder cancer: Operative technique and early outcomes

BACKGROUND

The objective was to elucidate the operative technique of robotic radical cholecystectomy (RRC) and to compare the early outcomes of RRC with open radical cholecystectomy (ORC) for gallbladder cancer (GBC).

METHODS

Patients who underwent RRC for suspected or incidental GBC between July 2015 and August 2018 were analyzed. Patients who underwent ORC during the same period and fulfilled the study criteria formed the control group.

RESULTS

During the study period, 27 patients who underwent RRC formed the study group (group A) and 70 matched patients who underwent ORC formed the control group (group B). Median surgical time was higher in group A (295 vs 200 minutes, P < 0.001). However, median blood loss (200 vs 600 mL, P < 0.001), postoperative hospital stay (4 vs 5 days, P = 0.046) and postoperative morbidity (1 vs 15 patients, P = 0.035) were lower in group A. Median lymph node yield was 10 (range = 2-21) for group A and 9 (range = 2-25) for group B, and was comparable (P = 0.408). During a median follow up of 9 (1-46) months, two patients in group A developed recurrence (no port site recurrence).

CONCLUSION

RRC is safe and feasible and the short-term results are compared with ORC.

Safety and oncologic outcomes of robotic liver resections: A systematic review

The robotic system has emerged as a new minimally invasive technology with promising results. We sought to systematically review the available literature on the safety and the oncologic outcomes of robotic liver surgery. A systematic review was conducted using Medline (PubMed), Embase and Cochrane library through November 12th, 2017. A robotic approach may be a safe and feasible surgical option for minor and major liver resections.
