In the present study, both groups had similar analgesic requirements, and no supplemental analgesics were required. Also, patients in both groups were discharged on the day after surgery. Considering OTX015 manufacturer the non-conclusive nature of these two variables, emphasis was placed exclusively on the VAS. Two recent meta-analyses by Garg et?al. and Markar et?al. used VAS to analyze postoperative pain at 24 hours. As in the present study, they concluded that there was no statistically significant difference between postoperative CLC and SILC pain scores [19, 20]. Postoperative pain is dependent on multiple factors such as inflammation due to tissue handling, infection at the incision site, bile leakage, intraperitoneal pressure and the pain threshold of the patient [21-23]. In the present study, only scar site and size varied, so it is likely that these incision-specific Rucaparib solubility dmso variables had the greatest bearing on pain scores. In SILC patients, a single transumbilical incision was to easily introduce the SILC port without causing much the trauma to adjacent soft tissue and thus reducing the inflammatory reaction and pain. In CLC patients, four different ports were introduced (two 11-mm ports and two 5-mm ports), and the length of the incisions were 1.5?cm and 1?cm, respectively. The liberal incisions in CLC facilitate easy passage of the ports. Another contributing factor to pain could be postoperative infection, which was largely absent in both groups. However, two SILC patients had minor infections at the incision site. None of the patients in either group had hematoma at the incision site. Some studies have shown that pain scores in SILC are higher than or comparable to that in CLC [24, 25]. This could be because SILC requires greater stretching and handling of the adjacent tissue to accommodate the insertion of the larger port and instruments through the single umbilical wound. In our study, we used a slightly longer incision to avoid stretching of the tissues and found the pain scores after SILC to be less than after CLC, but this difference was not statistically significant. On the postoperative day 7, although the SILC patients had statistically significant less pain (P?ALPI inflammation. SILC patients had a mean VAS of 1.16 (range, 1�C2), whereas CLC patients had a mean VAS of 2.56 (range, 1�C3). This pain was mild, and none of the patients required additional analgesics to control the pain. Although there was a statistically significant difference in the pain scores between the two groups (P?
