[Acute intermittent porphyria: a clinical case]. / La porfiria acuta intermittente: caso clinico.

The acute intermittent porphyria is a rare but very interesting disease from the surgical and anaesthesiological point of view. On the basis of recently observed case the Authors review clinical and pathophysiological data of this entity simulating a variety of acute abdominal conditions and involving important problems from the anaesthesiological and pharmacological point of view. As a matter of fact, the administration of some drugs can provoke a crisis that often involves serious complications (coma), sometimes lethal (respiratory paralysis). However, when a patient needs a surgical treatment for different reasons, the awareness of this condition enables to plan an anaesthesiological management free of risks.

[Abdominal Wells rectopexy with patch micromesh PTFE (Goretex)]. / Rettopessi per via addominale secondo Wells con patch mycromesh PTFE (Goretex).

The aim of this study is to discuss the surgical treatment of rectal prolapse. The surgical therapy offers many different options. Beginning from 1970 the anterior rectopexy has been considered a technique with good results, also in the elderly patient, when the general conditions allow it. Author's experience concerns the surgical treatment of 4 patients (2 males and 2 females) with complete symptomatic rectal prolapse, treated with anterior access laparotomy with the technique of Wells, leaving 1/3 of anterior rectal wall free from suture. Patients had a regular postoperative course; only in 1 case there was a delay of the canalization. At 1 year after the rectopexy the results are satisfactory, with absence of recurrence and troubles of the evacuation. The high percentage of successes of the anterior rectopexy is founded on: 1) the mobilization of the rectum, complete or only posterior; the rectal vessels must be respected, but there isn't consent on the opportunity of the section of the lateral ligaments. It may cause a denervation of the anorectum with an alteration of the fecal evacuation; and 2) the process of cicatritation by the employment of mesh and PTFE material that fix the rectum to the sacred maintains it as in the desired position.
