Interbody cages and PLIF technique for the reconstruction of the anterior column has evolved from a controversial to an accepted and effective procedure. 285 patients operated on with Ogival Cages have been reviewed considering the indications, complications rate and the overall satisfying patient outcome. Despite the fact that this surgical technique is both time consuming and involves great care on the part of the surgeon, spondylolisthesis and degenerative disc derangements are good indications for cages and a high rate of good clinical results has been achieved with this method. Learning curve and design improvement may minimize the risk of complication.

The Impact

Rupture of the anterior cruciate ligament (ACL) is a common injury. The objective of the current study was to evaluate if the learning curve has an impact on surgical time and postoperative clinical outcomes after anatomic single-bundle anterior cruciate ligament reconstruction (ACLR) using an outside-in tunnel drilling hamstrings technique. The learning curve has a positive impact on surgical time but has no influence on postoperative clinical outcomes at short time follow-up.

Objectives It was recently shown that biomechanical stability achieved with a locking compression plate (LCP) for ventral cervical fusion in horses is similar to the commonly used Kerf cut cylinder. The advantages of the LCP system render it an interesting implant for this indication. The goal of this report was to describe surgical technique, complications and outcome of horses that underwent ventral fusion of two or three cervical vertebrae with an LCP. Methods Medical records of eight horses were reviewed for patient data, history, preoperative grade of ataxia, diagnostic imaging, surgical technique and complications. Follow-up information was obtained including clinical re-examination and radiographs whenever possible. Results Two (n = 5) or 3 (n = 3) cervical vertebrae were fused in a mixed population with a median age of 9 months, median weight of 330 kg and median grade of ataxia of 3/5. A narrow 4.5/5.0 LCP (n = 6), a broad 4.5/5.0 LCP (n = 1) and a human femur 4.5/5.0 LCP (n = 1) were applied. Two horses were re-operated due to implant loosening. Six patients developed a seroma. Long-term complications included ventral screw migration in four, spinal cord injury in one and plate breakage in two horses at 720 to 1116 days after surgery. Outcome was excellent in three, good in four, poor in one patient. Clinical Significance The use of an LCP for ventral cervical vertebral fusion is associated with good clinical results. However, a careful surgical technique is required to further reduce the complication rate.

Environmental Sounds

Adhering to the surgical technique outlined in the protocol for the Nucleus implant has resulted in over 100 patients worldwide obtaining significant benefit from multichannel stimulation. A detailed analysis of the results in 40 patients shows that it improves their awareness of environmental sounds and their abilities in understanding running speech when combined with lipreading. In addition, one third to one half of the patients also understand significant amounts of running speech without lipreading and some can have interactive conversations over the telephone. It is clear that any insertion trauma is not significant, which is confirmed by the excellent clinical results.

Abstract Background and study aims Endoscopic submucosal dissection (ESD) allows en bloc resection of large colorectal lesions but ESD experience is limited outside Asia. This study evaluated implementation of ESD in the treatment of colorectal neoplasia in a Western center. Patients and methods Three hundred and one cases of colorectal ESD (173 rectal and 128 colonic lesions) were retrospectively evaluated in terms of outcome, learning curve and complications. Results Median size was 4 cm (range 1 – 12.5). En bloc resection was achieved in 241 cases amounting to an en bloc resection rate of 80 %. R0 resection was accomplished in 207 cases (69 %), RX and R1 were attained in 83 (27 %) and 11 (4 %) cases, respectively. Median time was 98 min (range 10 – 588) and median proficiency was 7.2 cm2/h. Complications occurred in 24 patients (8 %) divided into 12 immediate perforations, five delayed perforations, one immediate bleeding and six delayed bleedings. Six patients (2 %), all with proximal lesions, had emergency surgery. Two hundred and four patients were followed up endoscopically and median follow-up time was 13 months (range 3 – 53) revealing seven recurrences (3 %). En bloc rate improved gradually from 60 % during the first period to 98 % during the last period. ESD proficiency significantly improved between the first study period (3.6 cm2/h) and the last study period (10.8 cm2/h). Conclusions This study represents the largest material on colorectal ESD in the west and shows that colorectal ESD can be implemented in clinical routine in western countries after appropriate training and achieve a high rate of en bloc and R0 resection with a concomitant low incidence of complications. ESD of proximal colonic lesions should be attempted with caution during the learning curve because of higher risk of complications.

Abstract Purpose: To describe a novel surgical technique for iridodialysis repair using iris retractor segments and report its clinical results.Methods: 53 eyes of 53 patients who underwent surgery for iridodialysis repair were enrolled in this retrospective study. Data recorded from patient files consisted of age, sex, history of trauma, surgical indications and type of surgery, preoperative and postoperative corrected distance visual acuity (CDVA), intraocular pressure (IOP), complications, and follow-up time. The novel, minimally invasive surgical technique was explicitly described in detail.Results: Mean follow-up time was 34.4 (range 12-84) months. The subjects were 29 (54.7%) men and 26 (45.3%) women, and the mean age was 56.6±14.0 years. Iridodialysis repair performed using one segment in 37 (69.8%) eyes, two segments in 15 (28.3%) eyes, and three segments in 1 (1.9%) eye. Pupilloplasty was performed in 17 eyes due to wide pupil diameter. The iridodialysis repair was combined with lens removal in 48 eyes, and anterior vitrectomy was performed in 10 eyes. CDVA significantly improved after surgery (p<0.001). Post-traumatic IOP rise was the most common complication, and six patients needed medical therapy for glaucoma control.Conclusion: Iridodialysis repair using iris retractor segment is a minimally invasive technique and found to be safe and effective, providing less surgical manipulation and surgical time than other techniques.

Abstract BACKGROUND Technological improvements frequently outpace the publication of randomized, controlled trials in surgical patients. This makes the application of new surgical techniques difficult as surgeons solely use clinical experience to guide changes in their practice. OBJECTIVE To quantitatively examine the learning curve of incorporating new technology into a surgical technique and discuss the clinical significance of incorporating this new technology into daily practice. To identify areas of improvement for operative efficiency and safety. METHODS A retrospective observational study examining quantitative measures of operative efficiency and safety from 2009 to 2017 in 454 consecutive patients undergoing stereo-electroencephalography depth electrode implantations. RESULTS The transition to a new robotic technique significantly improved operative times (196 min [95% CI 173-219] vs 115 min [95% CI 111-118], P &lt; .0001). Cumulative sum (CUSUM) analysis demonstrated that mastery of the robotic technique took much longer than the frame-based technique (operative time peak at case 75 vs case 25, plateau of 150 vs 10 cases). Although hemorrhage rates using different vascular imaging techniques did not appear to differ using traditional statistical analysis (magnetic resonance imaging, MRI 22.3%, computed tomography angiography, CTA 17.9%, angiogram 18.1%, likelihood ratio χ2 = 4.84, P = .30), CUSUM analysis suggested MRI as the vascular imaging modality leading to higher hemorrhage and symptomatic hemorrhage rates at our center. CONCLUSION This experience demonstrates an improvement in operative efficiency through a series of changes made using clinical experience and intuition while transitioning to a completely new paradigm. CUSUM analysis identified potential areas for improvement in both operative efficiency and safety if used in a prospective manner.
