Postoperative pain
Patient reports of endoscopic group with ”almost no pain” or ”slight
pain” are all patient reports, and all patients do not need painkillers.
Among them, 25% of patients who have experienced pain in need of
painkillers have undergone microsurgery. 6 hours after operation, the
pain was calculated by the numerical rating scale. The average pain
score of microscopic examination group was 5.80(4-8) and that of
endoscopic group was 3.45(1-6), which was statistically significant
(P<0.05, Figure 5A).
