Comment on “Prospective Analysis of 246 Fires of da Vinci SureForm SmartFire Stapler in Colorectal Cancer: First Indian Study”

Dear Editor, We read with interest the recently published article by Somashekhar et al.1 While the authors deserve credit for addressing an under-reported technical aspect of robotic rectal surgery and for capturing automated intraoperative device metrics, several methodological and interpretive concerns merit attention. First, the absence of a contemporaneous or matched control group significantly undermines the study’s central premise of technological effectiveness. Without comparison to laparoscopic or conventional powered staplers, the reported advantages in angulation, clamp success or cartridge utilisation remain observational rather than inferential. The conclusion that SureForm staplers contribute to improved distal transection is, therefore, speculative and not causally established. Second, the study places disproportionate emphasis on mechanical and engineering endpoints (clamp attempts, articulation angles and firing durations) while underrepresenting clinically meaningful outcomes. Anastomotic integrity is asserted largely in a binary fashion without standardised grading of complications, structured imaging follow-up or reporting of delayed leaks. Furthermore, omission of Clavien–Dindo morbidity classification, reintervention rates and long-term oncologic outcomes (local recurrence or disease-free survival) restricts the real-world clinical relevance of the findings. Third, the statistical methodology is limited to descriptive analysis, which is insufficient to validate claims of device superiority or clinical safety in a heterogeneous surgical population. Subgroup analyses – especially for high-risk cohorts such as males with narrow pelvis, obese patients or postradiation rectums – would have been more informative than aggregated averages. Fourth, the study acknowledges academic grant support from the device manufacturer, yet fails to adequately address the risk of industry-associated positive bias. When a proprietary platform constitutes the investigative variable, rigorous safeguards such as blinded analysis, independent validation or cost-neutral comparator arms become essential. Their absence weakens confidence in the objectivity of outcome interpretation. Finally, the cost implications of robotic staplers are acknowledged but not analysed objectively. Given the steep financial burden of robotic platforms in low- and middle-income countries, future studies must incorporate cost–utility analysis or cost-effectiveness analysis to justify clinical translation in terms of reduced complications, length of stay or reoperation savings at scale. In summary, while the article is valuable as an initial technical report, its conclusions overreach the evidence presented. The study is best interpreted as a feasibility analysis rather than a validation of clinical superiority. Larger randomised trials incorporating control arms, objective clinical endpoints and economic evaluation are essential before widespread adoption can be justified. Despite these limitations, the authors must be commended for highlighting a critical but under-reported step in rectal surgery – distal transection mechanics. The manuscript successfully shifts attention from traditional oncologic outcomes to surgical workflow dynamics and device-based precision medicine.
