Robot-assisted Partial Splenectomy
0 Views •
2026
This protocol describes a robot-assisted partial splenectomy for a benign splenic tumor. The robotic approach optimizes spleen preservation by enhancing surgical precision, minimizing blood loss, and improving postoperative outcomes. Key surgical steps include meticulous splenic hilum dissection, selective vascular ligation, intraoperative ultrasonography, and controlled parenchymal transection.

Three Different Protocols of Corneal Collagen Crosslinking in Keratoconus: Conventional, Accelerated and Iontophoresis
0 Views •
Cited by 30 •
2015
Corneal collagen cross-linking (CXL) is the only conservative treatment currently available to halt keratoconus progression by improving the biomechanical rigidity of the corneal stroma. The aim of this manuscript is to highlight the methods of three different protocols of CXL: conventional CXL (C-CXL), accelerated CXL (A-CXL), and iontophoresis CXL (I-CXL).
FAQs
These boundaries become recognizable as injured tissue progresses through inflammation and cellular death, while neighboring tissue retains blood flow and the capacity to recover. The contrast between local damage and surviving adjacent tissue creates a transition zone that clinicians can identify during assessment. Thus, the line reflects differing tissue states rather than a simple surface mark.
Changes in position or clarity can signal that the relationship between damaged and potentially recoverable tissue is changing. A line that shifts or becomes less distinct may alter the estimated extent of disease, while a stable, clear boundary may support a more consistent assessment. Clinicians interpret these changes with other findings rather than relying on them alone.
Visual boundaries provide clinically useful information about tissue viability, but they do not represent the entire assessment. Imaging and other clinical findings add information that can clarify disease extent and support interpretation of the visible transition. Using these sources together improves planning, particularly when clinicians must distinguish tissue that may recover from tissue requiring intervention.
Clinicians examine the affected area for the visible transition between damaged and apparently viable tissue, then consider its location and clarity in relation to the wound or diseased region. Repeated assessment can identify changes that suggest progression or response to treatment. This approach supports a more informed estimate of disease extent during examination and wound assessment.
The observed boundary helps clinicians estimate how much tissue is affected and where viable tissue may remain. That information can guide planning for debridement or amputation while supporting efforts to preserve tissue with recovery potential. Because the visible line is interpreted with imaging and other clinical findings, it contributes to decisions rather than determining them independently.
Changes in the line’s position or clarity can provide a clinical indication that the underlying tissue process is progressing or responding to treatment. Monitoring these features may help clinicians reassess disease extent and adjust planning. The findings are most useful when combined with examination, wound assessment, imaging, and other clinical information collected during follow-up.
