The bulge after minimally invasive hernia surgery is likely to be caused by infection, or local hernia recurrence. 1. Infection: because even minimally invasive surgery will have a wound, although small, but there is a certain risk of infection, if the infection will cause the wound to appear fluid accumulation, resulting in the appearance of bulging. 2. Local hernia recurrence: because even after minimally invasive hernia surgery, there is a certain probability of local hernia recurrence, the need to go for a second operation. But the second surgery and then minimally invasive surgery is generally more difficult than the first time, because the first minimally invasive surgery is carried out in the intermucosal space, after the operation may cause mucosal adhesions. If you experience bulging after minimally invasive surgery for hernia, you should go to the hospital immediately for examination, find out the situation and actively cooperate with the doctor’s treatment, and under the doctor’s guidance to carry out the appropriate treatment, do not indiscriminate use of medicines, so as not to miss the opportunity of the disease.
