He highlighted the issue after new figures revealed that in the six months between April and September this year only 3996 operations took place through the health authority.
That compares to an average of 8720 in Dumfries and Galloway during the same period in the years 2016 to 2019, suggesting a potential 4724 operations were not carried out during the same months this year.
Whilst Mr Mundell says that everything must be done to tackle increasing numbers of Covid cases, he stresses the SNP Government must not forget about patients who are waiting for delayed vital operations and procedures for other conditions.
He also called on the SNP Scottish Government to ensure that NHS Dumfries and Galloway and frontline staff are given resources to ensure patients receive urgent clarification as to whether their operations will go ahead or not.
Mr Mundell said: “Whilst we must do all we can to tackle the rise in Covid cases, the SNP must ensure patients in Dumfries and Galloway who are waiting for vital operations are not simply forgotten about.
“It is concerning that potentially in the region of 4724 could have been cancelled or put on hold in the last six months.”
Mr Mundell added: “This winter, waiting times for operations in the region must not be allowed to spiral out of control.”
