Comparison of robotic-assisted and conventional laparoscopy in the management of adnexal masses

Outcomes of robotic and laparoscopic surgery for benign gynaecological disease: a systematic review

Benign gynaecological diseases are usually treated with minimally invasive approaches. Robotic surgery seems an alternative to laparoscopic surgery. No definitive conclusions have yet been made regarding comparison of robotic versus laparoscopic surgery for benign diseases. In this scenario, we performed a systematic review in order to assess the advantages and disadvantages of laparoscopy versus robotic surgery and conclude whether laparoscopy should be replaced by robotic surgery for the treatment of benign gynaecological conditions, following the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) Statement. We included 64 studies: no significant difference was observed regarding overall complication rate; no significant benefit of robotic approach was demonstrated regarding length of hospital stay and conversion to laparotomy; furthermore, robotic surgery is more easily used by non-experienced surgeons, while it is more expensive and characterised by longer operative time. In conclusion, current evidence indicates neither statistically significant nor clinically meaningful differences in surgical outcomes between robotic and laparoscopic surgeries for benign gynaecological diseases. Impact statementWhat is already known on this subject? Benign gynaecological diseases are usually treated with minimally invasive approaches. Nevertheless, no definitive conclusions have yet been made regarding comparison of robotic versus laparoscopic surgery for benign diseases.What do the results of this study add? No significant difference was observed regarding overall complication rate; no significant benefit of robotic approach was demonstrated regarding length of hospital stay and conversion to laparotomy; furthermore, robotic surgery is more easily used by non-experienced surgeon, while it is more expensive and characterised by longer operative time.What are the implications of these findings for clinical practice and/or further research? Robotic surgery should not replace laparoscopy for the treatment of benign gynaecological conditions; in addition, gynaecologic surgeon should offer robotic surgery for benign diseases only after a proper counselling and a balanced decision-making process involving the patient.

Perioperative outcomes in a nationwide sample of patients undergoing surgical treatment of ovarian endometriomas

OBJECTIVE

To evaluate the perioperative outcomes of premenopausal women undergoing cystectomy or oophorectomy for ovarian endometriomas (OMAs) and other benign neoplasms.

DESIGN

Retrospective cohort study.

SETTING

Clinical database containing information from 580 US hospitals.

PATIENT(S)

Women 18 to 50 years old who underwent ovarian cystectomy or oophorectomy for benign indications between 2010 and 2020.

INTERVENTION(S)

We compared procedure route, length of hospital stay, and complication rates by surgical indication (OMA vs. other benign neoplasms) and surgical procedure (cystectomy vs. oophorectomy).

MAIN OUTCOME MEASURE(S)

Thirty-day perioperative adverse events following adnexal surgery, including conversion to laparotomy, blood transfusion, ileus, urinary tract injury, bowel injury, readmission, and death.

RESULT(S)

We identified 120,208 ovarian cystectomies (28,182 OMAs and 92,026 other indications) and 53,476 oophorectomies (8,622 OMAs and 44,854 other indications). During cystectomy, patients with OMAs more commonly experienced conversion to laparotomy (5.1% vs. 3.1%) and readmission (8.5% vs. 7.1%). For oophorectomies, patients with OMAs less frequently had minimally invasive surgery (55.8% vs. 64.8%) or outpatient procedures (33.8% vs. 41.8%). Urinary tract and bowel injuries were rare. Multivariable logistic regression demonstrated that the presence of OMA predicted composite complications during cystectomy (adjusted odds ratio [aOR] 1.23, 95% confidence interval [CI] 1.18-1.28) but not during oophorectomy (aOR 1.05, 95% CI 0.99-1.12). Patients with OMAs had 1.37 times the odds of a composite complication during oophorectomy than during cystectomy (95% CI 1.28-1.47).

CONCLUSION(S)

Patients undergoing ovarian cystectomy for OMAs had higher rates of perioperative adverse events than patients undergoing ovarian cystectomy for other benign neoplasms. Laparotomies were performed more often during oophorectomies for OMAs than for other benign indications.

Survey of current practices and opinions of German Society of Gynecologic Endoscopy members regarding the treatment of ovarian neoplasia by robotic surgery

PURPOSE

As data on this topic are sparse and contradictory, we aimed to ascertain the opinions of the members of the German Society of Gynecologic Endoscopy (AGE) regarding the use of robotic surgery in the treatment of ovarian malignancies.

METHODS

In 2015, an anonymous questionnaire was sent to AGE members to assess their views on the treatment of ovarian malignancies by robotic surgery according to T stage and the current treatment practices in their facilities.

RESULTS

Of the 228 respondents, 132 (58%) were fellows or attending physicians and 156 (68%) worked at university hospitals or tertiary referral centers. Most [n = 218 (96%)] respondents reported treating < 10% of their patients using robotic surgery. Respondents felt that T1 and borderline ovarian tumors, but not T2 (51%) or T3/4 (76%) tumors, should and could be treated by robot surgery. 162 (71%) respondents considered the currently available data on this subject to be insufficient, and 42% indicated their willingness to participate in clinical studies on the applicability of robotic surgery to the treatment of T1/2 ovarian tumors.

CONCLUSION

The majority of AGE members surveyed considered robotic surgery to be an option for the treatment of T1 ovarian malignancies and borderline ovarian tumors. However, prospective randomized studies are needed to determine the relevance of robotic surgery in this context.

Minimally Invasive Excision of a Giant Paratubal Cyst: Case Report and Management Review

Paratubal cysts are usually incidentally found due to being small and asymptomatic adnexal structures. Enlargement to more than 15 cm concurrent with late presentation in an adult is rare. We present the case of a 36 cm diameter cyst in a 31-year-old female whose symptoms involved overactive bladder, abdominal bloating, and pressure. Radiologic findings suggested that it extended from the xiphoid and pubic symphysis. Removal was through a minimally invasive technique.

Practice Bulletin No. 174: Evaluation and Management of Adnexal Masses

Adnexal masses (ie, masses of the ovary, fallopian tube, or surrounding tissues) commonly are encountered by obstetrician-gynecologists and often present diagnostic and management dilemmas. Most adnexal masses are detected incidentally on physical examination or at the time of pelvic imaging. Less commonly, a mass may present with symptoms of acute or intermittent pain. Management decisions often are influenced by the age and family history of the patient. Although most adnexal masses are benign, the main goal of the diagnostic evaluation is to exclude malignancy. The purpose of this document is to provide guidelines for the evaluation and management of adnexal masses in adolescents, pregnant women, and nonpregnant women and to outline criteria for the identification of adnexal masses that are likely to be malignant and may warrant referral to or consultation with a gynecologic oncologist.
