OBJECTIVES This study was undertaken at the Department of Obstetrics and Gynaecology of the Charlotte Maxeke Johannesburg Academic Hospital to determine if the use of formal guidelines and a standardised surgical technique would increase the rate of vaginal hysterectomy (VH) and result in an overall decline in open abdominal hysterectomy (AH). STUDY DESIGN All women admitted between July 2001 and December 2014 for hysterectomy due to benign conditions, meeting the guidelines criteria (vaginally accessible uterus, uterus ≤ 12 weeks size or ≤ 280 g on ultrasound examination and pathology confined to the uterus) were included. The surgical route was determined using the Unit surgical decision tree algorithm. In cases where the pathology was not confined to the uterus or success in VH was uncertain, laparoscopic assisted vaginal hysterectomy (LAVH) was performed. The VH procedures were performed by the residents in training, under the supervision of specialists with large experience in vaginal surgery. In addition to the patient characteristics and surgical approach to hysterectomy, length of hospital stay, intra-operative and immediate post-operative complications were also recorded and analysed. RESULTS A year before the initiation of the study, the percentage of all VHs undertaken in the Department was 9.8 % (mainly performed for utero-vaginal prolapse). During the study period, 1143 vaginal procedures (1017 VHs and 126 LAVHs) were performed. The most common indications were cervical dysplasia, uterine fibroids, dysmenorrhoea or abnormal uterine bleeding, adenomyosis, endometrial hyperplasia and chronic pelvic pain. Introducing a formal clinical decision tree algorithm and a standardised surgical technique resulted in an increase in the rate of VH to 48.4 % and overall decline in open AH from 91.2%-51.6%. Thus, the VH/AH ratio increased from 1/9 at the beginning of the study (July 2001) to 1/1 by its end (December 2014). In all cases, VH was performed without the need to convert the vaginal to the abdominal route. CONCLUSION The use of institutional guidelines for determining the hysterectomy route and a standardised VH technique resulted in an increased number of performed VHs. This provided an essential opportunity for residents to acquire, improve and maintain the skills required to safely perform VH.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has raised some important interrogations on minimally invasive gynaecological surgery. The International Society of gynaecological Endoscopists (ISGE) has taken upon itself the task of providing guidance and best practice policies for all practicing gynaecological endoscopists. Factors affecting decision making processes in minimal invasive surgery (MIS) vary depending on factors such as the phase of the pandemic, policies on control and prevention, expertise and existing infrastructure. Our responsibility remains ensuring the safety of all health care providers, ancillary staff and patients during this unusual period. We reviewed the current literature related to gynecological and endoscopic surgery during the Coronavirus Disease 19 (COVID-19) crisis. Regarding elective surgery, universal testing for SARS-CoV-2 infection should be carried out wherever possible 40 h prior to surgery. In case of confirmed positive case of SARS-CoV-2, surgery should be delayed. Priority should be given to relatively urgent cases such as malignancies. ISGE supports medical optimization and delaying surgery for benign non-life-threatening surgeries. When possible, we recommend to perform cases by laparoscopy and to allow early discharges. Any procedure with risk of bowel involvement should be performed by open surgery as studies have found a high amount of viral RNA (ribonucleic acid) in stool. Regarding urgent surgery, each unit should create a risk assessment flow chart based on capacity. Patients should be screened for symptoms and symptomatic patients must be tested. In the event that a confirmed case of SARS-CoV-2 is found, every attempt should be made to optimize medical management and defer surgery until the patient has recovered and only emergency or life-threatening surgery should be performed in these cases. We recommend to avoid intubation and ventilation in SARS-CoV-2 positive patients and if at all possible local or regional anesthesia should be utilized. Patients who screen or test negative may have general anesthesia and laparoscopic surgery while strict protocols of infection control are upheld. Surgery in screen-positive as well as SARS-CoV-2 positive patients that cannot be safely postponed should be undertaken with full PPE with ensuring that only essential personnel are exposed. If available, negative pressure theatres should be used for patients who are positive or screen high risk. During open and vaginal procedures, suction can be used to minimize droplet and bioaerosol spread. In a patient who screens low risk or tests negative, although carrier and false negatives cannot be excluded, laparoscopy should be strongly considered. We recommend, during minimal access surgeries, to use strategies to reduce production of bioaerosols (such as minimal use of energy, experienced surgeon), to reduce leakage of smoke aerosols (for example, minimizing the number of ports used and size of incisions, as well as reducing the operating pressures) and to promote safe elimination of smoke during surgery and during the ports’ closure (such as using gas filters and smoke evacuation systems). During the post-peak period of pandemic, debriefing and mental health screening for staff is recommended. Psychological support should be provided as needed. In conclusion, based on the existent evidence, ISGE largely supports the current international trends favoring laparoscopy over laparotomy on a case by case risk evaluation basis, recognizing the different levels of skill and access to minimally invasive procedures across various countries.

Objectives: 1) to compare short term clinical results with standard abdominal hysterectomy (AH); 2) to investigate the feasibility of registrar training in VH by laparoscopic assistance; 3) to investigate the impact of laparoscopy in changing the route of hysterectomy in women assessed as being unsuitable for VH on clinical examination. Methods: 104 women scheduled for AH for benign uterine conditions were enrolled in this study, meeting the following criteria: uterine size ≤14-week pregnancy, width ≤9cm and length ≤14cm. Clinical ovarian pathology and uterine prolapse were exclusion criteria. Patients were divided in 2 groups matched with respect to age, parity, previous pelvic surgery and indications for hysterectomy. Prior to VH laparoscopic assessment of pelvic organs was performed for 58 of the 104 patients in this study, 46 of these patients had abdominal hysterectomies without laparoscopic assessment. Results: All cases allocated to have VH facilitated by laparoscopic assessm...
