Abstract
Introduction: Colorectal cancer (CRC) is the third most common cancer in the world. According to Cancer Research UK, 42,000 new cases are diagnosed in the UK every year. The liver is the most common site of metastasis with 15 to 25% of patients presenting with synchronous colorectal liver metastasis (CRLM) at the time of diagnosis. Modern chemotherapy has resulted in improved survival rates. Patients with resectable disease, surgical resection remain the only potentially curative treatment. This study aimed to evaluate the short and long-term outcomes and directly comparing the effectiveness of laparoscopic and robotic CRLM surgery. Methodology: A literature search was performed and all studies that reported on operative characteristics, oncological outcomes for CRLM, morbidity or mortality and cost effectiveness on robotic or laparoscopic surgery were included. Present study was designed according to the PRISMA guidelines. Results: From the initial 575 manuscripts identified, 17 studies (9 laparoscopic & 8 robotic) were included in the final qualitative synthesis. Our study shows that robotic surgery can be used safely for colorectal liver resections with a limited conversion rate, blood loss, and postoperative morbidity. However, robotic and laparoscopic liver resection displays similar safety and feasibility for CRLM. Conclusion: Experienced Hepatobiliary surgeons can safely perform robotic surgery. Long-term oncological outcomes are unclear, but short-term perioperative results are comparable to those of laparoscopic liver resection. The main drawback of advanced robotic surgery is the associated cost and further studies are needed to clarify the exact role of robotics in liver surgery.
Highlights
Colorectal cancer (CRC) is the third most common cancer in the world
We reviewed the imaging study, it showed a small cystic lesion without enhancing portion at liver segment 5 that mimics intrahepatic duct dilatation and a cystic lesion at segment 6 that previously seen in preoperative imaging study
The previous study show a range of spectrum of hepatic cystic liver metastasis with histopathologic confirmation of diagnosis
Summary
Tumor burden at the diagnosis, variations in tumor burden due to chemotherapy, and tumor molecular profile seems to be the important factors prognostic for stratification of patients with CRLM receiving preoperative chemotherapy. Computed tomography demonstrated a pancreatic head mass that causing common bile duct and intrahepatic duct dilatation without evidence of advanced disease. She was underwent pyloric-preserving pancreatoduodenectomy and they discharge without complication. We reviewed the imaging study, it showed a small cystic lesion without enhancing portion at liver segment 5 that mimics intrahepatic duct dilatation and a cystic lesion at segment 6 that previously seen in preoperative imaging study. The computed tomography revealed increase sized of cystic lesion at segment 6 and development of ascites. The previous study show a range of spectrum of hepatic cystic liver metastasis with histopathologic confirmation of diagnosis.
