I browsed through the Program for the meeting and was kind of surprised at how much it looks like the program for past meetings. Many of the old topics are discussed, looking at similar questions like lightweight versus heavyweight mesh.
Here’s a study from a part of the world that hasn’t been discussed much. Japan. It’s a poster, so it is brief, but it might be the precursor to a full paper in the future.
From page 188 in the pdf Program file linked above.

Background: Chronic postoperative inguinal pain (CPIP) is known to be the most debilitating complications after inguinal hernia repair, while very few evidence has been reported in Japan. To determine the frequency and risk factors of CPIP, we perform a prospective, longitudinal multicentre observational cohort study.
…
Methods: Between September 2018 and March 2021, patients aged 20 years or more who planned to undergo elective inguinal hernia repair at 22 community hospitals, not hernia specialized centers, in Japan were enrolled. This study was registered in UMIN-CTR (Registry number; UMIN000033936) prior to enrollment of the first subject.
…
The proportion of patients reporting sense of discomfort was 22.5% at 3M, 21.4% at 6M, 18.0% at 12M, and 15.7% at 24M. The proportion of patients reporting hyperesthesia on the skin around the wound was 6.6% at 3M, 6.5% at 6M, 5.7% at 12M, and 4.9% at 24M. The proportion of patients reporting pain at ejaculation was 2.2% at 3M, 2.6% at 6M, 2.8% at 12M, and 3.3% at 24M. Hernia recurrence was observed in 1.1%, 1.5%, 2.3%, and 2.4% of patients at 3M, 6M, 12M, and 24M, respectively.
Conclusion: This is the first large prospective cohort study aimed to demonstrate the frequency of CPIP in Japan. Although its frequency is decreased over time, it can be problematic even at 2 years after surgery. Caution should be paid in patients with preoperative pain at rest, preoperative habitual intake of analgesics, and history of transabdominal prostatectomy. Laparoscopic surgery and/or technique without mesh fixation may be the option to avoid CPIP.
