A comparison of laparoendoscopic single-site surgery versus conventional procedures for laparoscopic donor nephrectomy: a Japanese multi-institutional retrospective study

Clinical study on laparoscopic minimally invasive surgery and transumbilical single-port laparoscopic surgery in the treatment of benign ovarian tumours and its influence on ovarian functions

OBJECTIVE

The objective of this study was to explore the influence of traditional laparoscopic surgery and transumbilical single-port laparoscopic surgery on ovarian function in patients with benign ovarian tumours.

MATERIALS AND METHODS

Forty-four patients with benign ovarian tumours who were treated in our hospital from January 2020 to June 2021 were selected and randomly divided into two groups, with 22 cases in each group according to random number table. The conventional group was treated with conventional laparoscopic surgery, while the modified group was treated with transumbilical single-port laparoscopic surgery. The measurement method was t -test, and the enumeration method was two tests. The clinical operation-related indicators, ovarian function (follicle-stimulating hormone, E 2 and luteinising hormone), complication incidence, Visual Analogue Scale (VAS) and landscaping satisfaction scores of the two groups were compared.

RESULTS

There were no significant differences in complications and operation duration between the two groups ( P > 0.05). After treatment, the ovarian function indexes and beautification satisfaction scores of the modified group were significantly superior to those of the conventional group ( P < 0.05). Besides, the intraoperative bleeding volume, post-operative exhaust time, hospital stay and three-dimensional VAS scores on day 1 and day 3 after surgery of the modified group were lower than those of the conventional group ( P < 0.05).

CONCLUSION

Transumbilical single-port laparoscopic surgery for benign ovarian tumours has a significant clinical effect, which can effectively reduce bleeding during the operation, improve ovarian function, relieve surgical pain, promote rapid post-operative recovery and improve patients' satisfaction with landscaping. It is worthy of clinical application.

A comparison of pre- and post-operative outcomes in living donors undergoing transperitoneal laparoscopic nephrectomy and open nephrectomy: a retrospective single-center study

BACKGROUND

Kidney transplantation is often regarded as the preferred therapy for end-stage renal disease. Several surgical procedures have been developed to reduce postoperative donor complications, while maintaining kidney quality.

OBJECTIVE

This study aimed to compare the preoperative and postoperative outcomes of living kidney donors who underwent either transperitoneal laparoscopic nephrectomy or open nephrectomy.

DESIGN AND SETTING

Retrospective study conducted in Istanbul, Turkey.

METHODS

Fifty-five living-related kidney donors underwent nephrectomy and were retrospectively divided into two groups: 21 donors who underwent open nephrectomy (Group 1) and 34 donors who underwent transperitoneal laparoscopic nephrectomy (Group 2).

RESULTS

In comparison to the donors who underwent open nephrectomy, those who underwent transperitoneal laparoscopic nephrectomy had significantly shorter postoperative hospital stays (2.3 ± 0.2 versus 3.8 ± 0.8 days, P = 0.003), duration of urinary catheterization (1.2 ± 0.8 days versus 2.0 ± 0.7 days, P = 0.0001), operating times (210 ± 27 minutes versus 185 ± 24 minutes, P = 0.02), and less blood loss (86 ml versus 142 ml, P = 0.048). There was no statistically significant difference between the two groups with regard to the estimated blood transfusion and warm ischemia time. The preoperative week, first postoperative week, and 1-month postoperative serum creatinine levels were comparable between the groups.

CONCLUSIONS

Laparoscopic donor nephrectomy can be safely performed at centers with expertise in laparoscopic surgery. Laparoscopic donor nephrectomy has better outcomes than open donor nephrectomy in terms of length of hospital stay, duration of urinary catheterization, operating time, and blood loss.
