Some evidence suggests that females have a lower pain threshold and a lower tolerance to painful stimuli.
Dr Uchiyama and colleagues investigated gender differences in postoperative pain after laparoscopic cholecystectomy.
The researchers used the visual analog pain scale score and the clinical course.
The research team included 100 patients, of which 46 were males and 54 were females.
The patients underwent laparoscopic cholecystectomy for cholecystolithiasis or gallbladder polyps without intraoperative complications.
An 8-mm penrose drain was retained for 42 hours below the liver bed.
All the patients were hospitalized for 4 days after laparoscopic cholecystectomy.

The team studied the pain reported by patients, the time course of changes in the highest body temperature, and the leukocyte count.
C-reactive protein level was also assessed comparatively for the male and female patients.
The researchers found that visual analog pain scale scores were higher for the female patients vs male patients at 24 and 48 hours after laparoscopic cholecystectomy.
The female patients used analgesics more frequently and had significantly higher body temperatures than the male patients on day 1 and 2 after surgery.
Dr Uchiyama's team concluded, “Early postoperative pain after laparoscopic cholecystectomy was more severe in female patients, and patients with high visual analog pain scale scores tended to use analgesics more frequently.”
