Centres
A total of 73 centres were registered with the BSGE between 2017 to
2020. Over this time period, the number of centres submitting data for
registered operations each year increased from 56 to 66 (Figure 1). Four
centres submitted registered operations for the first time in 2020,
while seven previously registered centres did not register any
operations in 2020. Out of 73 centres, 48 submitted registered
operations every year, 13 only for 3 years, 8 only for 2 years and 4
only for 1 year.
Operations
Over the time period from 2017 –
2020, a total of 5916 operations were performed for deep endometriosis
requiring pararectal dissection at BSGE-accredited centres (Figure 2).
The total number of registered operations increased by an average of
13.5% per year between 2017-2019, then decreased by 49.4% between
2019-2020.
At a centre-level, 60 endometriosis centres had reduced operation
numbers in 2020 compared with the average for 2017-2019, while 9 centres
had increased numbers of operations. Overall, the annual median number
of operations per centre decreased from 21 operations to 12.5
operations, with a median decrease in operations per centre of 51.0%
(IQR 29.4% – 75.0%).
Between 2017 and 2019, on average 33.0% of patients had no surgery on
the bowel, 60.2% underwent shaving of endometriosis from the bowel
surface, 1.8% underwent a disc resection and 5.0% underwent resection
of a segment of bowel. In 2020, 34.5%, 59.3%, 2.6% and 3.6% of
patients underwent no bowel surgery, bowel shave, disc resection and
segmental bowel resection respectively, which was not significantly
different to previous years (p=0.08).
Regions
At a regional level, all 11 administrative regions of Great Britain had
reduced numbers of BSGE-registered operations for endometriosis in 2020
compared with averages for 2017-2019, with a median 56.6% decrease
(range 6.13% - 68.62%) (Figures, 3 Figure 4). Regions had a median of
1.49 deaths from COVID-19 per 1000 population (range 0.80 – 1.91). At a
regional level, reduction in these operations was significantly
correlated with COVID-19 death rates
(r=0.56, 95% CI of r 0.048 –
1.00, p=0.037).
