Laparoendoscopic Single-Site Total Laparoscopic Hysterectomy: Clinical Factors that Affect Operative Times and Techniques to Overcome Difficulties

Comparison between transumbilical and transvaginal morcellation of a large uterus during single-port-access total laparoscopic hysterectomy

Objective

To compare the perioperative outcomes of transumbilical morcellation (TUM) and transvaginal morcellation (TVM) of a large uterus (≥500 g) during single-port-access total laparoscopic hysterectomy (SPA-TLH).

Methods

A total of 57 patients who underwent SPA-TLH for a large uterine myoma and/or adenomyosis (uterine weight ≥500 g) between March 2013 and July 2017 were included. For specimen retrieval, TUM was performed for 30 patients and TVM for 27 patients.

Results

Perioperative outcomes, including total operative time, tissue extraction time, extension of skin incision length, estimated volume of blood loss, changes in postoperative hemoglobin level, length of postoperative hospital stay, postoperative pain, and uterine weight, were compared between the 2 groups. No significant differences were observed in the baseline characteristics except for a history of cesarean section (TUM vs. TVM: 83.3% vs. 14.8%, P=0.002) and history of vaginal delivery (TUM vs. TVM: 6.7% vs. 88.8%, P=0.001). The total operative time, tissue extraction time, extension of skin incision length, estimated volume of blood loss, changes in postoperative hemoglobin level, length of postoperative hospital stay, and postoperative pain did not significantly differ between the two groups. The uterine weight was significantly higher for patients who underwent TUM than for those who had TVM (median [range]: 735 g [520–1,380 g] vs. 622 g [514–975 g]; P=0.042).

Conclusion

TUM during SPA-TLH is a feasible technique for extracting large uteri weighing ≥500 g. This procedure is suitable for patients without a history of vaginal delivery or a narrow vaginal cavity.

Laparoendoscopic single-site surgery compared with conventional laparoscopic surgery for benign ovarian masses: a systematic review and meta-analysis

OBJECTIVE

We aimed to evaluate the safety, efficiency and preferred indication for laparoendoscopic single-site surgery (LESS) compared with conventional laparoscopic (CL) surgery for benign ovarian masses.

DESIGN

A systemic review and cumulative meta-analysis were performed in line with the criteria of Grading of Recommendations Assessment, Development and Evaluation: levels of evidence and grades of recommendation.

DATA SOURCES

We comprehensively searched the electronic databases including PubMed, Medline, Embase and the Cochrane Library in November 2018.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

We included all randomised controlled trials (RCTs) and retrospective studies published in recent 10 years, which investigated the performance of LESS versus CL in patients at all ages with benign ovarian masses.

RESULTS

Four RCTs and nine retrospective studies published in recent decade including 1542 cases (744 cases for LESS and 798 cases for CL) were identified. Perioperative complication was consisted of intraoperative and postoperative complications, including ileus, wound infection or dehiscence and incisional hernia. Although LESS has less postoperative analgesic consumption (46.78% and 79.25%; OR: 0.49; 95% CI: 0.33 to 0.74, p<0.001) and shorter hospital stay (weighted mean difference (WMD): -0.24 days; 95% CI: -0.35 to -0.14; p<0.001), CL has less perioperative complications (6.59% and 2.85%; OR: 2.08; 95% CI: 1.05 to 4.11, p=0.04) and shorter operative time (WMD: 3.43 min; 95% CI: -0.03 to 6.88; p=0.05). Body mass index, history of previous abdominal surgery, size of adnexal mass, estimated blood loss and postoperative pain scores did not differ significantly between two techniques.

CONCLUSIONS

The indications of LESS for benign ovarian masses are similar to CL and it has better postoperative recovery. However, with less perioperative complications, CL surgery is safer than LESS.

Comparison of clinical outcomes and postoperative quality of life after surgical treatment of type II submucous myoma via laparoscopy or hysteroscopy

Objective

This study was performed to compare the clinical outcomes, advantages, and disadvantages of laparoscopic myomectomy (LM) and transcervical resection of myoma (TCRM) in the treatment of type II submucous myoma.

Methods

In total, 136 patients with type II submucous myoma with a tumour diameter of 4 to 5 cm were randomly assigned to the hysteroscopy group or laparoscopy group.

Results

The operative duration was shorter and the intraoperative bleeding volume was lower in the hysteroscopy than laparoscopy group. The success rate of the single-stage operation was obviously higher in the laparoscopy than hysteroscopy group. The duration of postoperative antibiotic use and the length of hospital stay were shorter in the hysteroscopy than laparoscopy group. The time to complete healing of the muscle layer was shorter in the hysteroscopy than laparoscopy group. The rate of intraoperative complications was lower in the hysteroscopy than laparoscopy group.

Conclusion

Both hysteroscopic and laparoscopic surgery have beneficial effects in the treatment of type II submucous myoma. Hysteroscopic surgery has the advantages of a short operative duration, low intraoperative bleeding volume, fast postoperative recovery, and high quality of life. Laparoscopic surgery involves many intraoperative complications and slow recovery of ovarian function.

Benign multicystic peritoneal mesothelioma treated with laparoendoscopic single site surgery: a case report and review of the literature

Benign multicystic peritoneal mesothelioma (BMPM) is rare and difficult to diagnose before surgery. We report a case of BMPM incidentally discovered during laparoendoscopic single site surgery (LESS) for treatment of a pelvic mass. A 47-year-old Korean menopaused woman presented to our outpatient clinic with a pelvic mass. She had a history of right ovary cystectomy with adhesiolysis at a local hospital in 2010. Imaging study of the pelvis revealed a multilocular cystic mass. LESS was performed and multiple grapelike clusters of cysts were seen in the uterus, cul-de-sac, both adnexa, pelvic wall, and omentum. The appendix was grossly free. Frozen biopsy confirmed BMPM. Excision of multiple cyst clusters of cysts, resection of the uterus with both adnexa, appendectomy, omentectomy, and adhesiolysis were performed with LESS. She is well for 2 years with no recurrence. BMPM should be included in the differential diagnosis when small multichamber cystic mass is found on ultrasonography.
