[Complications due to mechanical sutures in laparoscopic surgery: bowel obstruction caused by staple. Case report and literature review].

Bowel obstruction after laparoscopic surgical operation is reported only in few cases. The incarceration of bowel loop occurs into the port site more frequently. The case of a young woman, subjected to laparoscopic appendectomy is reported: bowel obstruction occurs on the third postoperative day caused by a staple of the mechanical suture on the caecum, hooked to bowel mesentery.

[A modified technique of gallbladder dissection from the liver during laparoscopic cholecystectomy. Personal technique].

Background: Gallbladder injures during cholecystectomy happens more frequently when surgical operation is conduced under laparoscopic (16%) rather than laparotomic (8%) access. A modification of the technique of dissection of the gallbladder from the liver is presented, suggesting a progression from the medium to the lateral side. This technique should facilitate the division of the organs and, above all, limit the gallbladder iatrogenic injures.

[The effectiveness of long-term treatment of severe secondary hyperparathyroidism with intravenous calcitriol].

Aims: To evaluate the efficacy of intravenous calcitriol as a means of significantly reducing plasma PTH in long-term hemodialysis with severe hyperparathyroidism.

Experimental Design: prospective study.

Follow-up: 12 months.

[Therapeutic use of heparan sulfate in nephrotic syndrome: rational use].

We report the beneficial effects of heparan sulfate administration in nephrotic syndrome (NS) in reducing the degree of proteinuria, in ameliorating the chylomicron removal defect and the hypercoagulable state and, consequently, in slowing down the progression to uraemia.
