Table 3 Postoperative pain according to the different studies
Studies | Methods | Results |
|---|---|---|
Choi 2011 | Patients who needed more than two doses of analgesics for operative site pain were recorded. | Postoperative pain was occurred in seven patients in the TS group and six patients in the RS group (p = 0.994). |
Lau 2002 | The severity of pain at rest and on coughing was assessed daily with a linear analogue pain score on a scale from0 to 10 after the operation. During the hospital stay, the surgeon determined the pain score during the ward round. After discharge, all patients were taught to fill in a pain score chart at home daily to document pain at rest and on coughing. All pain score charts were collected by the surgeon during the first follow-up clinic visit. | No difference in postoperative daily pain scores at rest and on coughing between the two groups (p = NS). |
Li 2019 | Pain was measured by visual analog scale (VAS) (range: 0–10), a 10 cm line was drawn and marked equidistant 1–10, with 0 representing no pain and 10 representing the most severe pain. Patients with VAS greater than 5 were considered to have acute pain or chronic pain. | There were no significant differences between the two groups in the level of acute pain (p = 0.73). During the follow-up period, there were no chronic pain issues observed in either group. |
Ruze 2018 | Postoperative pain based on a visual analog scale where 0 indicated no pain and 10 indicated the worst pain imaginable. Pain was determined at seven days, one month, and three months. | Pain at seven days p = 0.502 Pain at one-month p = 0.933 Pain at three months p = 0.285 |
