General Laser Complications
The potential complications encountered in endoscopic laser surgery are the same as those normally
encountered in conventional endoscopic surgery.
x Acute pain may occur immediately following laser therapy and may persist for as long as 48 hours.
x Immediately following laser therapy, the patient may experience fever and leukocytosis, which are
commonly associated with tissue destruction. These issues generally resolve without treatment.
x Laser ablated tissue may become necrotic or infected after treatment. In case of any concern about
possible infection, appropriate treatment should be carried out.
The following complications could be serious and could result in death:
x Patients may experience bleeding at the site of laser therapy. Post-treatment hematocrits are
recommended to identify this potential complication.
x Sepsis can result from performing any surgical procedure. In case of any concern about possible sepsis,
appropriate evaluations should be made.
x Perforation may occur as a result of laser treatment. In order to diagnose perforations, patients must
be followed carefully post-operatively with appropriate tests.
Warning: As with any conventional surgical operations, adverse reactions may occur following
treatment. Use cautiously with patients who have had difficulty with previous laser procedures.
Complications and risks are the same of the conventional laser surgery. These include, but are not limited to,
the following:
Complications and non-thermal risks:
x Perforation;
x Aspiration;
x Induced hemorrhage;
x Allergic reaction to medication;
x Hypertension;
x Arrhythmia;
x Pain;
x Distension due to gases;
x Pneumothorax;
x Infection
Complications and thermal risks (acute)
x Induced hemorrhage;
x Ulceration;
x Perforation;
x Edema;
x Pain;
x Fever;
x Leukocytosis;
x Chills
Complications and thermal risks (critical)
x Healing delay;
x Perforation;
x Stenosis;
x Delayed hemorrhage;
x Sepsis;
x Embolism.
