On the other hand, colonoscopy offers significant improvements in detection rates for CRC but it also has important disadvantages associated, as inconvenience, high economic burden and potential major complications (bleeding, perforation) [ 13, 14].
The main surgical complications were: major bleeding (1), rectal perforation (1), ureter lesion (1).
Serious complications (such as perforation, major bleeding, and death) occur in 3.1 colonoscopies per 1000 screened.
Major perioperative complications (major bleeding, false route, oesophageal perforation, failure to insert cannula, pneumothorax) were evenly distributed between the groups (guide wire dilating forceps, 13/171; Ciaglia Blue Rhino, 9/171) and minor complications were somewhat more frequent with Ciaglia Blue Rhino tracheotomy.
Perforation occurs in approximately 1 in 1000 colonoscopies, major bleeding occurs in approximately 3 per 1000, and 1 3 individuals in 10000 undergoing colonoscopy die of complications from the procedure [ 28, 41, 49– 51].
Perforation occurs in approximately 1 in 1000 colonoscopies, major bleeding occurs in approximately 3 per 1000, and one to three patients undergoing colonoscopy die of complications from the procedure[ 6, 19, 26– 28].
Early major complications were higher as compared to fully percutaneous devices: the incidence of pericardial effusion requiring pericardiocentesis was between 11% and 20%, and the incidence of major bleeding was 9% while another 9% of patients suffered LAA perforation needing open chest surgery.
Complications of ulcers include bleeding, perforation of the abdominal wall, and obstruction of the gastrointestinal tract.
Major bleeding is less frequent.
The safety outcomes were major bleeding, minor bleeding and death.
