Liam J. Kelly
Chairman, President and Chief Executive Officer at Teleflex
Thank you, Larry, and good morning, everyone. On this morning's call, we will discuss the fourth quarter results, provide some commercial updates and introduce our financial guidance for 2024. We had a solid finish to 2023 as momentum seen through the year continued into the fourth quarter. For the quarter, Teleflex revenues were $773.9 million, a year-over-year increase of 2.1% and an increase of 0.7% on a constant currency basis. As a reminder to investors, there were five fewer shipping days year-over-year in the fourth quarter. The shipping day impact in the quarter was an estimated $57 million or approximately a 7.4 percentage point reduction in constant currency growth year-over-year. When adjusting for the shipping day impact, the implied constant currency growth was 8.1% year-over-year.
Fourth quarter adjusted earnings per share was $3.38, a 4% decrease year-over-year. During the quarter, utilization continued to return towards normal seasonality. From a macro perspective, we witnessed a stable to improving environment for material inflation and supply chain. These dynamics generally track to our expectations for the full year. For the full year 2023, we had a strong performance with revenues reaching $2.975 billion, which represents 6.5% constant currency growth year-over-year, while adjusted earnings per share was $13.52.
As we look to 2024, we anticipate a stable procedure environment with seasonality in line with pre pandemic levels. Although the Teleflex portfolio is not likely to benefit from pent-up demand due to the focus on critical care procedures, we would anticipate that staffing will continue to see improvements during the year. Supply chain dynamics largely stabilized through 2023 and we expect to see continued improvements in 2024. Teleflex has broad global manufacturing capabilities and we continue to assess vertical integration opportunities to gain further control of our supply chain.
Turning to inflation. There were elements of improvement during 2023, including sea freight and raw materials. For 2024, we are assuming some further disinflation, but note that costs remain somewhat elevated relative to historic levels and are above 2023.
Now let's turn to a deeper dive into our fourth quarter revenue results. I will begin with a review of our geographic segment revenues for the fourth quarter. All growth rates that I refer to are on a constant currency basis and reflect the negative impact of five fewer shipping days year-over-year unless otherwise noted, America's revenues were $450.6 million, a 1.9% decrease year-over-year driven by surgical and vascular and reflective of the five fewer shipping days in the quarter. In particular, we saw year-over-year growth in our interventional anesthesia and interventional urology businesses despite the fewer shipping days in the quarter.
EMEA revenues of $152.4 million decreased 2.7% year-over-year driven by anesthesia and surgical and reflective of the impact of the fewer shipping days. Urology products, interventional and vascular businesses generated the highest shipping days adjusted growth in the quarter. Turning to Asia. Revenues were $88.3 million increasing 12.6% year-over-year. Revenue growth was broad based across the region with strong double-digit increases in Korea, India and China. The performance in the quarter was driven by strong commercial execution and solid underlying demand.
Let's now move to a discussion on our fourth quarter revenue by global product category. Commentary on global product category growth for the fourth quarter will also be on a year-over-year constant currency basis and reflects the impact of the five fewer shipping days. On a shipping days adjusted basis, the sequential growth in the fourth quarter trended in line with our expectations with vascular and anesthesia growth rates improving while interventional and surgical slowed. Starting with vascular access, revenue decreased 1.2% to $186.7 million. Along with the fewer shipping days, the year-over-year growth also reflected the impact of the previously announced endurance catheter recall.
The quarter was led by year-over-year growth for EZ-IO and other access despite headwinds from the fewer shipping days. Of note, we achieved double-digit growth in our underlying pick business when excluding the negative impact of the endurance recall. We continue to see opportunities for share gains in the peripheral access market and our new product initiatives will help play a role. During the quarter, we continued to execute on our launch activities for our next-generation navigation device and new pick dialect.
Moving to interventional. Revenue was $135.6 million, up 7.2% year-over-year. Despite the impact of the fewer selling days, we demonstrated solid growth, which underscores our positive momentum as we continue to make good progress with our growth drivers. Turning to anesthesia, revenue declined 3.4% year-over-year to $98.2 million. Among our larger product categories, hemostatic product performed well in the quarter with strong double-digit growth, partially offset by declines in atomization and ET tubes as we recover from the recall which occurred earlier in 2023.
In our surgical business, revenue was $109.6 million, down 2% year-over-year against a tough comparison. Our underlying trends in our core surgical franchise continue to be solid, including our ligation portfolio. For 2023, Titan generated revenues in excess of $12 million. For interventional urology, revenue was $93 million representing an increase of 4.2%. Starting with Palette, which we acquired in October 2023, revenues in the fourth quarter were modestly better than expectations with outperformance of Barrigel.
For UroLift, the office remains a challenge as we continue our efforts to stabilize this site of service. In the international markets, UroLift revenue saw healthy growth in Japan, while in China, our initial launch activities remain on plan with a focus on training surgeons and gaining reimbursements. OEM had another solid quarter with revenues increasing 10.9% year-over-year to $82.6 million. The strength in the quarter was broad based across our portfolio with all product categories recording year-over-year growth, including continued strength in microcatheters. Fourth quarter other revenue declined 10.2% to $68.2 million year-over-year. As previously disclosed, fourth quarter other revenues reflects the early December 2023 exit of the MSA by Medline and accounted for the majority of the year-over-year revenue decline.
That completes my comments on the fourth quarter revenue performance. Turning to some commercial and clinical updates. Following the acquisition of Palette Life Sciences on October 10, 2023, I am pleased to report that the integration is tracking to our expectations. We have completed initial cross functional product sales training for selected members of our legacy UroLift sales force and our dual bag reps are now interacting with clinicians in the field. Our focus remains on expanding the use of rectal spacing in the treatment of prostate cancer and we are engaging with urologists and radiation oncologists. Barrigel is a differentiated rectal spacer that is clinically proven to significantly reduce unwanted radiation exposure.
Moving to UroLift. We continue to expand our foundation of clinical data that supports the use of UroLift as a safe and effective minimally invasive treatment for BPH. In November 2023, we highlighted a new peer review study in the Nature Journal Prostate Cancer and Prosthetic Diseases that reinforces the position of the UroLift system as the gold standard in minimally invasive surgical treatment for BPH. Results suggested that within one year of BPH surgery, one in 20 patients may require retreatment regardless of whether they receive a TURP, GreenLight resume or UroLift.
Additionally, at one year, procedural complications requiring a return procedure in the outpatient setting was lowest following UroLift and highest following resume. The average time to the first complication was the longest for UroLift. At five years, retreatment was lowest for TURP and statistically similar between GreenLight and UroLift. The retreatment rate for UroLift is comparable to published controlled trial rates, thereby underscoring the durability of the UroLift system. We continue to focus on supporting UroLift with clinical data and note that we have eight sponsored research abstracts that have been accepted for presentation at major urological meetings in 2024.
Turning to an update related to our surgical business unit. We have completed the launch activities for the Gore Seamguard Bioabsorbable
Staple Line Reinforcement Material to be used with the Titan stapler. The ability to offer synthetic buttressing material alongside the unique features of the Titan stapler should enable Teleflex to further address surgeon clinical needs and preferences in the sleeve gastrectomy market. Lastly, as we look into 2024, we will continue to advance our new product introductions with a number of launches across our business units.
In our interventional business, we expect to receive FDA marketing clearance and launch the Ringer catheter in the second half of 2024. Ringer incorporates a unique balloon design that allows blood to flow through a vessel while the balloon is inflated. We will initially launch with a PTCA indication, but we have completed enrollment in a vessel proliferation trial that will be utilized to seek FDA label expansion.
In our surgical business, we anticipate launching new ligation products, including an automated polymer clip applier in the second half of 2024. We will also continue to refresh our laryngoscope families with a series of launches during the year. Our anesthesia business unit is also on track for new product launches, including updated technology in our ECIO business that would enable expansion of our user base for which we expect FDA approval in 2024. We will provide more details upon launch.
That completes my prepared remarks. Now I would like to turn the call over to Tom for a more detailed review of our fourth quarter financial results. Tom?
