The procedure is quite safe, fast, with a low rate of complications.
The procedure is quite safe, fast, with a low rate of complications, effective when the objective is to close the anastomosis.
In the treatment of obesity, argon plasma is indicated for those patients who performed Bypass or Capella surgery and who after 2 years or more of surgery have kidney weight. Therefore, it especially treats the kidney weight in those who have undergone Bypass bariatric surgery.
This treatment that seeks a correction of the surgical anatomy so that the restrictive effect of the bariatric surgery, possibly lost with the passage of time, is rescued. The treatment should not be judged by each session, but by the whole treatment.
The results of APC have been promising. Several scientific articles and clinical studies have shown interesting results. Individually it is difficult to predict what will happen by way of results. But the statistic has been like this: 80% of the patients lose 70 to 100% of the watered weight, 10% lose no or little weight and 10% lose even more than they watered. 90% of the patients will need 2 to 3 sessions for the ideal closure of the anastomosis. About 10% will succeed in that goal as early as the first session.
This is highly dependent on the diameter of the anastomosis.
Not specifically because of the technique, but because it is intended only for one type of bariatric surgery: Bypass. So any other bariatric surgery can not apply the method. Therefore, it is only necessary that the clinical conditions of the patient allow the performance of an endoscopic procedure with sedation.
An endoscopy is usually necessary to assess whether the patient is a candidate for the procedure, if he/she has an extended anastomosis. Coagulation tests may be ordered to evaluate the patient’s coagulation profile.
The procedure is performed like an endoscopy, where the endoscopist passes a double lumen catheter inside the endoscope, going to the region to be applied.
An electric current is fired through one lumen of the catheter and argon gas is passed through the other lumen and when both meet at the tip of the catheter, near the mucosa, they form a coagulation plasma that denatures the applied tissue.
APC is a fairly safe treatment with a low rate of major complications. The most frequent complication, which occurs in 1% of patients, is exaggerated closure of the anastomosis. In this case we will have to dilate by endoscopy.
Normally the patient feels no pain or side effects after the session and can return to work the following day. Between the third and fifth week the patient may feel a tightening of the passage and the patient feels difficult to digest. This soon improves.
