Outcomes of robotic liver resections for colorectal liver metastases. A multi-institutional analysis of minimally invasive ultrasound-guided robotic surgery.

Background: Current evidence supporting robotics to perform minimally invasive liver resection is based on single center case series reporting surgical outcomes in heterogeneous groups of patients. On the contrary, relatively scarce data specifically focusing on secondary hepatic malignancies is available. The objective of this study is to assess short- and long-term outcomes following liver resection for colorectal liver metastasis on a multi-institutional series of patients.

Robotic distal pancreatectomy with selective closure of pancreatic duct: surgical outcomes.

Pancreatic fistula is the main post-operative complication of distal pancreatectomy associated with other further complications, such as intra-abdominal abscesses, wound infection, sepsis, electrolyte imbalance, malabsorption and hemorrhage. Surgeons have tried various techniques to close the stump of the remaining pancreas, but the controversy regarding the impact of stapler closure and suture closure of the pancreatic stump is far from resolved. In this study, we reported our technique and results of robotic assisted distal pancreatectomy with ultrasound identification and consequent selective closure of pancreatic duct.

Robotic Rectal Resection With a Single-docking Technique Thanks to the Rotation of the R3 Arm.

Background: Robotic surgery for rectal resection presents some advantages compared with the traditional technique; however, it also presents some limitations, especially due to the multiple changes of surgical fields. We describe a new technique to perform low-anterior resection using single docking with the rotation of the third arm and our perioperative results.

Materials And Methods: A total of 31 patients who underwent low-anterior rectal robotic resection with single-docking technique using robotic daVinci SI (Surgical Intuitive System) were included in the study.

Robot-assisted laparoscopic gastrectomy for gastric cancer.

Phase III evidence in the shape of a series of randomized controlled trials and meta-analyses has shown that laparoscopic gastrectomy is safe and gives better short-term results with respect to the traditional open technique for early-stage gastric cancer. In fact, in the East laparoscopic gastrectomy has become routine for early-stage gastric cancer. In contrast, the treatment of advanced gastric cancer through a minimally invasive way is still a debated issue, mostly due to worries about its oncological efficacy and the difficulty of carrying out an extended lymphadenectomy and intestinal reconstruction after total gastrectomy laparoscopically.

Time-to-administration in postoperative chemotherapy for colorectal cancer: does minimally-invasive surgery help?

The optimal delay in the start of chemotherapy following rectal cancer surgery has not yet been identified. However, postponed adjuvant therapy has been proven to be connected with a significant survival detriment. We aimed to investigate whether the time to initiation of adjuvant treatment can be influenced by the application of minimally invasive surgery rather than traditional open surgery.

Objective: Robot-assisted surgery has been reported to be a safe and effective alternative to conventional laparoscopy for the treatment of rectal cancer in a minimally invasive manner. Nevertheless, substantial data concerning functional outcomes and long-term oncological adequacy is still lacking. We aimed to assess the current role of robotics in rectal surgery focusing on patients' functional and oncological outcomes.

Minimally invasive surgical approach to pancreatic malignancies.

Pancreatic surgery for malignancy is recognized as challenging for the surgeons and risky for the patients due to consistent perioperative morbidity and mortality. Furthermore, the oncological long-term results are largely disappointing, even for those patients who experience an uneventfully hospital stay. Nevertheless, surgery still remains the cornerstone of a multidisciplinary treatment for pancreatic cancer.
