Background/Aim: Laparoscopic single-port surgery has emerged as a growing trend in minimally invasive surgery. Single-port access is preferred among women undergoing gynecologic surgery who have cosmetic concerns about scarring. Furthermore, this approach results in comparable clinical outcomes to standard laparoscopic surgery and perioperative morbidity rates have been reported to be low. The hypothesis is that a single-port technique might offer such advantages over the standard multi-port laparoscopy as less postoperative pain and better cosmetic results by decreasing abdominal wall tissue trauma. The potential disadvantages of single-port approaches are the larger umbilical incision and the technical difficulties. There are only a few randomized studies in the literature that investigate the value and safety of single-incision laparoscopic surgery in gynecological surgery. The aim of this study was to compare the safety and quality of life in patients who undergo single-incision laparoscopic assisted vaginal hysterectomy and those who undergo conventional laparoscopic assisted vaginal hysterectomy.
Methods: In a prospective randomized trial, 64 patients from three different centers in Germany were randomized (1:1) to conventional laparoscopic assisted vaginal hysterectomy (n=32) or single-incision laparoscopic assisted vaginal hysterectomy (n=30). Data was collected on 60 patients who fulfilled the criteria.
Results: The baseline characteristics of patients were similar in both groups. The mean operative time was comparable in both groups (68.2 vs 73.6 min., p = 0.409). Within the two groups, no differences were seen regarding estimated blood loss (p = 0.915), intra- and postoperative complications (p = 0.944), and wound infection rates (p = 0.944). Patients within the single-incision laparoscopic surgery group experienced significantly less pain in the first 24 hours postoperatively (p = 0.006), while pain scores at days 3, 5, 7 and 2 months postoperatively were comparable.
Conclusion: This study demonstrates that single-incision laparoscopic assisted vaginal hysterectomy is a reliable and safe setup in gynecologic surgery. Compared to conventional laparoscopic assisted vaginal hysterectomy, Notably, patients undergoing single-incision laparoscopic assisted vaginal hysterectomy experienced less pain postoperatively.
With improvements in breast imaging, mammography, ultrasound and minimally invasive interventions, the detection of early breast cancer, non-invasive cancers, lesions of uncertain malignant potential, and benign lesions has increased. However, with the improved diagnostic capabilities comes a substantial risk of false-positive benign lesions and vice versa false-negative malignant lesions. A statement is provided on the manifestation, imaging, and diagnostic verification of isolated benign breast tumours that have a frequent manifestation, in addition to general therapy management recommendations. Histological evaluation of benign breast tumours is the most reliable diagnostic method. According to the S3 guideline and information gained from analysis of the literature, preference is to be given to core biopsy for each type of tumour as the preferred diagnostic method. An indication for open biopsy is also to be established should the tumour increase in size in the follow-up interval, after recurring discrepancies in the vacuum biopsy results, or at the request of the patient. As an alternative, minimally invasive procedures such as therapeutic vacuum biopsy, cryoablation or high-intensity focused ultrasound are also becoming possible alternatives in definitive surgical management. The newer minimally invasive methods show an adequate degree of accuracy and hardly any restrictions in terms of post-interventional cosmetics so that current requirements of extensive breast imaging can be thoroughly met.
