A comparison of perioperative outcomes between extraperitoneal robotic single-port and multiport radical prostatectomy with the da Vinci Si Surgical System / 亚洲男科学杂志(英文版)

To evaluate outcomes between extraperitoneal robotic single-port radical prostatectomy (epR-spRP) and extraperitoneal robotic multiport radical prostatectomy (epR-mpRP) performed with the da Vinci Si Surgical System, comparison was performed between 30 single-port (SP group) and 26 multiport (MP group) cases. Comparisons included operative time, estimated blood loss (EBL), hospital stay, peritoneal violation, pain scores, scar satisfaction, continence, and erectile function. The median operation time and EBL were not different between the two groups. In the SP group, the median operation time of the first 10 patients was obviously longer than that of the latter 20 patients (P < 0.001). The median postoperative hospital stay in the SP group was shorter than that in the MP group (P < 0.001). The rate of peritoneal damage in the SP group was less than that in the MP group (P = 0.017). The pain score and overall need for pain medications in the SP group were lower than those in the MP group (P < 0.001 and P = 0.015, respectively). Patients in the SP group were more satisfied with their scars than those in the MP group 3 months postoperatively (P = 0.007). At 3 months, the cancer control, recovery of erectile function, and urinary continence rates were similar between the two groups. It is safe and feasible to perform epR-spRP using the da Vinci Si surgical system. Therefore, epR-spRP can be a treatment option for localized prostate cancer. Although epR-spRP still has a learning curve, it has advantages for postoperative pain and self-assessed cosmesis. In the absence of the single-port robotic surgery platform, we can still provide minimally invasive surgery for patients.

Negative pressure wound therapy combined with skin grafting improves surgical wound healing in the perianal area.

Management of large tissue defects resulting from local wide resection of perianal is a clinical challenge for surgeons. The aim of the present study was to investigate the efficacy of negative pressure wound therapy (NPWT) following skin grafting on perianal surgical wound healing.Included in this study were 12 patients with perianal tumors who received skin grafting after perianal tumor resection between December 2012 and December 2014. A self-designed negative pressure drainage device was then applied to maintain a standard negative pressure at -150 mm Hg and removed on day 8 postoperation. The outcome was recorded immediately after NPWT and at 6-month follow-up.All skin grafts survived without infection, hematoma, and necrosis in all 12 patients. No tumor recurrence was detected during 6-month follow-up. Natural folds were observed around the anus. All patients showed normal bowel movements.NPWT following skin grafting was effective for perianal surgical wound healing and infection prevention, thus benefiting anatomical and functional recovery of the anus.
