Complication after a colonoscopy

The most frequent complication after a colonoscopy is post-bleeding, as mucosal biopsies are usually taken or polyps removed if necessary. Mucosal biopsies are obtained using small forceps, which tear out small pieces of mucosa. Normally, after a short observation during the colonoscopy, the donor sites no longer bleed and heal completely within a few days.

Polyps are removed with a sling, which simultaneously coagulates the tissue so that the tissue defect is directly closed. It is possible, however, that the blood clot on a wound will come off and cause a new bleeding. Depending on the intensity of the bleeding, this can then manifest itself as blood deposits on the stool, which can even lead to anemia.

Complication after wisdom tooth surgery

The roots of the wisdom teeth are very deep in the jawbone, so that after their removal deep wounds in the jaw predominate. On the one hand it can bleed from these wound pockets, which can be treated well with a tamponade. On the other hand, pathogens can settle here, which is a more difficult situation.

The wound pockets can only be cleaned to a limited extent due to the sensitivity of the injured mucosa and are constantly in contact with saliva and food. Contamination of the wound cannot therefore be prevented. Depending on the severity of the infection, therapy with a mouthwash or antibiotic therapy must then be initiated.

Complication after Hallux surgery

The complications after a hallux operation depend strongly on the surgical technique chosen by the doctor. In any case, although the bony malpositioning of the big toe is always corrected, there are various procedures and fixation techniques to straighten the formerly “inclined axis”. If part of the bone is removed, there is always the risk of temporary instability of the joint with the increased risk of fractures or, more precisely, marginal bone fractures under stress.

If the joint is completely stiffened along a straight axis (so-called arthrodesis), the lack of movement of the toe and metatarsus relative to each other can lead to load-dependent pain, since the forefoot can no longer roll off properly. Bleeding is rare after a hallux operation, as vessels are not usually touched. Similarly, tendons and ligaments are not damaged, since the surgical techniques are limited to the bony joint only. Postoperative pain is therefore based on a substance defect of the bone and the “forced” new position of the bones in relation to each other, which can initially cause a “tension pain“.
