We used the definitions of complications set forth in the analyzed studies to divide the complications into six main categories.
Complications were also divided into complications that were related to the IRE or those related to associated procedures.
Furthermore, we divided the complications into early, midterm, and late complication according to the time of their occurrence.
Additional file 1: Resume table with complications divided in different complication groups.
We divided the complications into eight categories (see box): haemorrhage, infection, incomplete abortion, surgical evacuation, psychiatric morbidity, injury or other reason for surgical operation, thromboembolic disease, and death.
Complications were divided into general complications that were not related to the surgical procedure and specific postoperative complications related to the operation procedure.
Late complications were divided in surgical complications (such as capsular formation, infection, necrosis, and luxation of the prosthesis), and complaints related to cosmetic outcome (such as poor symmetry and dog ears).
Wound complications can be divided into minor complications (superficial infection, dehiscence, wound edge necrosis) and major complications (deep infection, osteomyelitis, plate fistula) [ 12].
Complications, divided in major and minor complications, are recorded during the follow up period of 1 year.
Reported complications during investigation were divided in minor complications, bleeding, perforation and severe respiratory insufficiency (need for intubation or mask ventilation).
