Summary
A novel 2D camera system for spinal surgery in Tanzania improved patient outcomes. While initial durotomy rates were higher, the system offers ergonomic and cost benefits for minimally invasive spine surgery (MISS).
Area of Science:
- Neurosurgery
- Spinal Surgery
- Minimally Invasive Spine Surgery (MISS)
Background:
- A novel 2D camera visualization system offers magnified views of the surgical field via a tubular retractor.
- This system represents a new technology for surgical visualization.
Purpose of the Study:
- To report the initial experience with a 2D camera-based visualization system for tubular spinal micro decompression surgery.
- To evaluate the feasibility and outcomes of this novel system in Tanzania.
Main Methods:
- A prospective cohort study included 17 patients with lumbar spinal stenosis or disc herniation.
- Data collected included demographics, surgical details, complications, hospital stay, and Numeric Rating Scale (NRS) scores over six months.
- Descriptive analysis was performed on the collected data.
Main Results:
- The study included 17 patients (59% male, mean age 61 years) with L4-L5 spinal stenosis being most common (65%).
- Mean preoperative NRS score was 8, with significant improvement sustained over six months.
- Durotomy occurred in 29% of patients, primarily during the first year, but no intraoperative nerve injuries were observed. Median hospital stay was 3 days, and 1 patient (6%) developed SSI.
Conclusions:
- The tubular-mounted digital camera visualization system is a feasible adjunct for MISS in Tanzania.
- The system provides advantages in ergonomics, training, and cost-effectiveness over operative microscopy.
- Outcomes improved with experience, despite an initial learning curve associated with durotomy.
