Background: The application of robotic staplers in surgeries has increased in recent years. Robotic platform enhances ability of the surgeon to directly control and manoeuvre staplers to achieve required angulation and sealing within the confines of the thorax and pelvis. Hence, in this study, we intended to learn the effectiveness of the SureForm™ SmartFire™ technology stapling system in various oncological procedures.
Patients and methods: Prospective study of 76 patients who underwent robotic-assisted total oesophagectomy, gastrectomies, hemicolectomies, low anterior resection/abdominoperineal resection and lobectomies/metastasectomy for respective malignancies for 16 months. Internal data log of the da Vinci surgical system for reload colour, reloads used, clamp attempts and staple fires used during each procedure along with patient's post-operative outcomes were recorded.
Results: One hundred and sixty-four firings have been made in 76 cases, with the majority being green reloads (76.8%) and average reloads for radical cystectomy 3.5, lobectomies/metastasectomy 3.44 and oesophagectomy 2.55. None of the cases had incomplete firings and required force-fire activation. In forty per cent of cases, the robotic stapler had to pause for sequential compression and seal. Seventy per cent of anterior resection procedures had at least one firing >45° beyond the laparoscopy limit. Collectively 52% SureForm stapler fires in anterior resection with >45° angle of fire. None of the cases had bleed or leak.
Conclusion: SureForm™ SmartFire™ robotic staplers can be used for various oncological surgeries with minimal peri-operative leak and bleeding and has better articulation in closed spaces. Further case-matched comparative studies with laparoscopic or handheld powered staplers would be required for useful operative decision-making and analyse the clinical outcomes.
