Single port laparoscopy (SPL): Retrospective study evaluating postoperative pain in comparison with conventional laparoscopy (CL)

Early return to work: Single-port vs. multiport laparoscopic surgery for benign ovarian tumor

Objective

To compare the return to work (RTW) time between single-port laparoscopic surgery (SPLS) and multiport laparoscopic surgery (MPLS) for benign ovarian tumors.

Methods

A cross-sectional cohort study was conducted, which consisted of 335 women of reproductive age with benign ovarian tumors and who were keen on returning to work as early as possible. Surgical outcomes, postoperative pain score, postoperative satisfaction with the cosmesis score (CS), and the RTW time of the SPLS group were compared with those of the MPLS group. Besides, the RTW time and CS were calculated from the questionnaire survey by a single specialized gynecologist.

Results

Women who met the inclusion criteria were included in the SPLS (n = 106) and MPLS groups (n = 229). The RTW time in the SPLS group (22.13 ± 27. 06 days) was significantly shorter than that in the MPLS group (46.08 ± 57.86 days) (P < 0.001). The multivariate Cox analysis results showed that age (HR = 0.984, 95% CI, 0.971−0.997, P = 0.020), SPLS (HR = 3.491, 95% CI, 2.422−5. 032, P < 0.001), and return to normal activity time (HR = 0.980, 95% CI, 0.961−0.998, P = 0.029) were independent factors of the RTW time.

Conclusions

SPLS may be advantageous in terms of shortening the RTW time for women with benign ovarian tumors.

The role of port site local anesthetic injection in laparoendoscopic single site surgery: a prospective randomized study

Objective

To investigate the role of port-site bupivacaine hydrochloride injection in laparoendoscopic single-site surgery (LESS) as a means of postoperative umbilical pain alleviation.

Methods

A total of 200 consecutive patients who underwent LESS from October 2018 to February 2019 were included in this randomized prospective case control study. The patients were alternatively assigned to either the study group (0.25% 10-mL bupivacaine hydrochloride injection at the 1.5-cm umbilical incision site after surgery) or the control group (no injection). All patients underwent surgery at the National Health Insurance Service Ilsan Hospital under the same operational setting by 3 board-certified gynecologists. Postoperative umbilical pain scores assessed using the visual analog scale were compared between the 2 groups as the primary outcome. Student's t-test, χ² test, and a linear mixed model were used for the statistical analysis. A P-value of <0.05 was considered to be statistically significant.

Results

The patients' age, body mass index, and menopausal status; type of surgery performed; and need for additional trocar insertion exhibited a significant difference between the bupivacaine injection and non-injection groups. After adjusting for various confounding variables, the postoperative umbilical pain scores measured at postoperative 2–3 hours, 6–10 hours, 1 day, and 3 days did not exhibit a significant difference between the 2 groups.

Conclusion

Port-site bupivacaine injection in LESS did not show any additive effect in alleviation of postoperative umbilical pain.

Outcome of Gynecologic Laparoendoscopic Single-Site Surgery with a Homemade Device and Conventional Laparoscopic Instruments in a Chinese Teaching Hospital

OBJECTIVE

To demonstrate various benign gynecologic diseases that can be performed by laparoendoscopic single-site surgery (LESS) with conventional laparoscopic instruments.

METHOD

Patients with benign gynecologic diseases that need ovarian cystectomy, fallopian tube resection, or myomectomy were divided into experimental group and control group, and perioperative outcomes of these patients were analyzed.

RESULTS

From November 2017 to May 2018, 65 LESS gynecological surgeries were performed, among which there were 25 ovarian cystectomies, 28 unilateral fallopian tube resections, and 12 myomectomies. All the surgeries were completed smoothly, and only one surgery needed one more additional port. No patients have severe complications. Operative time, intraoperative blood loss, and perioperative complications have no difference between the two groups. The LESS laparoscopy group had less postoperative pain scores and longer bowel recovering time, compared with the conventional laparoscopy group (<0.05).

CONCLUSION

Compared with traditional laparoscopy, LESS surgery with conventional laparoscopic instruments is feasible and safe, but postoperative exhaust time is longer than the control group.
