[Percutaneous endoscopic gastrostomy: study on 35 patients]. / Gastrostomía endoscópica percutánea: estudio de 35 enfermos.

BACKGROUND: A review of the technique, indications, complications and follow up of percutaneous endoscopic gastrostomy (PEG) was performed. METHODS: Thirty-five patients in whom a PEG had been placed according to the Ponsky technique from 1991 to 1993 were analyzed 27 of whom had neurologic disease, 6 tumoral diseases and 2 other causes. RESULTS: PEG was carried out in 33 patients with no incidences while the technique could not be performed in 2 since the point could not be identified by transillumination in the gastric wall. No immediate complications were observed. Seven minor early complications were presented as wound infection with the cannula being withdrawn in only one case due to persistence of the infection. Five late complications were reported: 1 severe (gastrocholic fistula) and 4 minor (2 cannula obstructions, 1 displacement and 1 infection). Evolution was followed in 31 patients with the cannula being withdrawn in 4 (2 because of complications and in the other 2 on initiation of oral diet). The cannula was substituted at 120 and 360 days in 2 patients. Sixteen patients died, 5 during the first 30 days due to the primary disease, with only one case (aspirative pneumonia) being related to the PEG. The PEG continues functioning in 11 patients. CONCLUSIONS: Percutaneous endoscopic gastrostomy for feeding is a simple technique which may be carried out in most patients with scarce severe complications, allowing a good nutritional state and improving the quality of life of patients requiring prolonged enteral feeding.

Intramuscular diclofenac sodium versus intravenous Baralgin in the treatment of renal colic.

A comparative, randomized, double-blind study of diclofenac sodium 75 mg im versus Baralgin (a combination drug composed of dipyrone and two spasmolytics) 5 mL iv was performed on 57 patients with renal colic. Both groups were comparable as to age, sex, pain evolution time before treatment, and no treatment for renal colic in the six hours preceding trial drug administration. No significant differences were found between the two groups with respect to the evolution of pain after the first dose or in the frequency of administration of a second dose. Tolerability was good in both groups, but sweating and pain throughout the vein were observed in one patient in the Baralgin group. We concluded that diclofenac sodium constitutes an excellent alternative to pyrazolone analgesics, with the advantages of being monotherapy and having good tolerability, when used as intramuscular injection in ambulatory patients.
