GSMED Imaging technical team — rigid endoscopy and minimally invasive surgery Colombia
Based on official Karl Storz technical specifications (IMAGE1 S RUBINA — 4K/NIR), Olympus Medical (VISERA ELITE II — OTV-S300), 4K laparoscopy clinical literature (SAGES 2024), and 2026 Colombian surgical equipment market data.
Rigid endoscopy and laparoscopy have their own image quality standards — Karl Storz and Olympus are the two historic global leaders in cameras and video towers for minimally invasive surgery. With the arrival of 4K in operating rooms, both brands offer state-of-the-art systems that compete directly. This technical comparison helps you decide which is the best investment for your surgical service in Colombia.
1. Context — rigid vs flexible endoscopy
Unlike flexible endoscopy systems (for gastroenterology and pulmonology), rigid endoscopy and laparoscopy systems use Hopkins rod optics — a rigid metal tube with glass lenses that transmit the image to an external camera connected to the proximal end. The quality of the Hopkins optics + the quality of the external camera determine the final image quality on the operating room monitor.

2. Karl Storz's differentiating advantage: NIR/ICG — infrared fluorescence
What is NIR/ICG fluorescence and why is it transforming surgery Karl Storz IMAGE1 S RUBINA NIR/ICG (Near Infrared / Indocyanine Green) technology allows real-time visualization of indocyanine green (ICG) fluorescence — a dye administered intravenously that accumulates in blood vessels and vascularized tissues. Under near-infrared (NIR) light, ICG "glows" green on the monitor. Game-changing surgical applications: (1) anastomotic perfusion assessment in colorectal surgery — identifies poorly perfused anastomoses before closure that would otherwise leak; (2) identification of bile ducts during laparoscopic cholecystectomy — reduces the risk of common bile duct injury; (3) sentinel lymph node biopsy in breast and colorectal cancer. Olympus VISERA ELITE II also has NIR/ICG capability in its version with the specific module.
3. SPIES vs CLARA+CHROMA — enhanced imaging in laparoscopy
🟦
SPIES (Karl Storz) — 4 image modes
SPIES (Storz Professional Image Enhancement System) is Karl Storz's enhanced imaging system for rigid endoscopy and laparoscopy. It offers 4 modes: (1) CLARA — brightening dark areas without overexposing light areas; (2) CHROMA — selective color saturation to improve tissue contrast; (3) CLARA+CHROMA — a combination of both; (4) NIR/ICG — infrared fluorescence. The surgeon can switch between modes with a button during the procedure.

🟠
CLARA+CHROMA (Olympus) — balanced image
Olympus VISERA ELITE II offers CLARA (dark area enhancement) and CHROMA (selective color saturation) enhanced imaging technologies — comparable in functionality to Karl Storz's equivalent modes. Integration with the rest of the Olympus ecosystem (monitor, recorder, documentation system) is a plus for institutions with existing Olympus equipment.

4. Complete technical comparison
| Parameter | Karl Storz IMAGE1 S | Olympus VISERA ELITE II | Advantage |
|---|---|---|---|
| Resolution | 4K — 3840×2160 | 4K — 3840×2160 | Equal — both 4K |
| Sensor system | Three-Chip CMOS 4K (3 sensors separated by RGB channel) | Single-Chip CMOS 4K | Karl Storz — three-chip offers greater color fidelity |
| NIR/ICG Fluorescence | Native integrated — RUBINA | Available with additional module | Karl Storz — native NIR without extra module |
| Enhanced imaging | SPIES: CLARA · CHROMA · CLARA+CHROMA · NIR | CLARA · CHROMA · NIR (with module) | Karl Storz — greater native integration |
| Optics compatibility | Compatible with all Karl Storz Hopkins optics (decades of stock) | Compatible with Olympus optics for laparoscopy | Karl Storz — larger catalog of available optics |
| OR (Operating Room) integration | OR1 NEO — complete operating room integration (video, image, data) | Endoscopy system VISERA ELITE II — basic integration | Karl Storz — comprehensive digital operating room solution |
| Base system price (Colombia) | USD 80,000–130,000 | USD 65,000–100,000 | Olympus — more affordable entry price |
| Installed base Colombia | Strong in university hospitals and high complexity | Growing — especially urology and gynecology | Karl Storz with greater surgical tradition |
| Instrument catalog | The widest on the market — decades of compatible instruments | Good catalog for its main specialties | Karl Storz — incomparable variety of instruments |
✅
Technical verdict: Karl Storz IMAGE1 S RUBINA wins in image quality (three-chip), native integrated NIR/ICG, instrument catalog, and integrated operating room solution. Olympus VISERA ELITE II wins in entry price and integration with the Olympus ecosystem for institutions that already have equipment from that brand. For high complexity surgery (oncological surgery, biliary surgery, high-risk anastomoses), the native NIR/ICG of the Karl Storz can be decisive.
5. Which one to choose according to your service?
| Service type | Choice | Reason |
|---|---|---|
| Oncological surgery (colorectal, gastric, hepatobiliary) | Karl Storz IMAGE1 S RUBINA | Native NIR/ICG for anastomotic perfusion assessment and sentinel node detection |
| High-volume laparoscopic cholecystectomy | Karl Storz IMAGE1 S | NIR/ICG reduces bile duct injury — the most serious complication of cholecystectomy |
| Arthroscopy — shoulder, knee, hip | Both — equivalent quality | In arthroscopy without the need for NIR, both systems are clinically equivalent |
| Endoscopic urology (TUR, laparoscopic nephrectomy) | Both valid | Olympus with greater historical presence in urology · Karl Storz with NIR for urothelial carcinoma |
| ENT and sinus surgery (FESS) | Karl Storz | Historic standard in ENT endoscopy with the largest catalog of available instruments |
| Institution with limited budget | Olympus VISERA ELITE II | 20–30% lower entry price with equivalent 4K quality for cases without the need for NIR |
Is indocyanine green (ICG) safe for patients?
Yes. Indocyanine green (ICG) is a pharmaceutical dye approved by the FDA for intravenous use in humans since 1959. It has a very favorable safety profile — it is exclusively eliminated by the liver in the bile, without renal metabolism. The only absolute contraindication is iodine allergy (ICG contains iodide). Adverse reactions are extremely rare (<0.01%) and generally mild (itching, hives). The typical dose for intraoperative fluorescence is 2.5–5 mg IV — well below the established safety limits.
