[Myocardial ischemia in general medicine and the revolution of coronary stents]

Since Gruentizg's first percutaneous transluminal ballon angioplasty in 1977 in Zurich, percuta. neous coronary intervention evolved significantly in order to overcome the numerous associated complications of each technique. Bare-metal stents (BMS) made their initial appearance followed by three generations of drug-eluting stents (DES). The use of bioabsorbable vascular scaffold stents (BVS) has become more frequent creating a temporary scaffold allowing healing of the endothelium within 2 years. In this article, we discuss the nomenclature of the main intravascular complications linked to percuta. neous coronary intervention such as stent thrombosis (ST), Instent restenosis (ISR), neoatherosclerosis, and stents evolution to overcome these complications. We will finally mention the new technologies of intracoronary imaging such as OCT (Optical Coherence Tomography) having an increasing vital role in percutaneous coronary intervention,

Is early enteral nutrition dangerous in acute non surgical complicated diverticulitis? About 25 patients fed with oral fiber free energetic liquid diet

BACKGROUND AND STUDY AIMS

Complicated Acute Colonic Diverticulitis (ACD) is usually treated by parenteral way thus keeping the bowel at rest. To date there are no clear recommendations regarding the route of nutrition administration. We study the safety of early feeding by oral energetic fiber-free liquid diet in non-surgical complicated ACD patients.

PATIENTS AND METHODS

From February 2008 to October 2011, 25 patients were admitted with complicated ACD and took part in this prospective study. Surgical and medical assessments were performed at admission. Initial treatment was given with perfusion, intravenous antibiotics and hydric diet. Within 72 hours of admission, antibiotic therapy was switched to oral administration for 5 up to 15 days depending on the progression of the disease. At the same time the patient received oral liquid fiber-free feeding. Solid but fiber-free diet was introduced 24h hours before discharge.

RESULTS

25 cases of ACD were complicated with covered perforation and/or abscess. Mean hospitalisation time was 10A.4 days. 23 cases had good recovery and discharged, while 1 case progressed to colonic stenosis during hospitalisation, requiring a sigmoidectomy with a one-time anastomosis with good recovery. One patient relapsed his abscess during hospitalisation despite CT guided drainage and required sigmoidectomy with transient ileostomy. The mean daily treatment and nutrition cost for the non-surgical 23 patients was 30 euros.

CONCLUSIONS

Early enteral nutrition in complicated ACD is feasible, not harmful, and reduce both, mean hospitalization time and treatment cost. Further studies comparing enteral with parenteral nutrition are necessary to confirm our hypothesis.
