Experimental study regarding the biocompatibility test of the Prolene (polypropylene abdominal mesh) product.

The polypropylene mesh, although is one of the most used prosthetic biomaterials for abdominal wall defects, proved not to be completely inert, generating from precocious foreign body inflammatory reactions (varying by individual reactivity, the amount of used material and its structure), to late complications such as chronic infections, stercoral fistulae or mesh migration. The present paper was aimed at studying the behavior of implants of this material in three different areas of the body of experimental animals, as follows: intramuscular, intraperitoneal and extraperitoneal. The observation time was 21 days and 90 days.

Elective Laparoscopic Cholangiography in Lithiasic Pathology. Intraoperative Selection Criteria.

Introduction: The introduction of laparoscopic techniques has caused the dispute between supporters of routine or elective intraoperative cholangiography to continue, but at present most authors recommend its elective practice on the basis of well-established preoperative and / or intraoperative indications, thus avoiding to carry out a large number of unnecessary procedures, with their inherent disadvantages and risks.

Method: A retrospective study was conducted over 20 years, comprising 100 elective laparoscopic cholangiographies.

Results: The most representative parameter for the indication of intraoperative laparoscopic cholangiography in choledochal lithiasis suspicion has proved to be common bile duct dilation of over 3mm, optionally accompanied by cystic calculi and / or main bile duct dilation over 10mm.

Clinical and Paraclinical Criteria of Patient Selection for the Non-operative Treatment in Completely Responsive Rectal Cancer (after Neoadjuvant Radiochemotherapy).

Introduction: Neoadjuvant radiotherapy is included in the treatment protocols for rectal tumors in stages = T3. The use of neoadjuvant radiotherapy allowed the limit of surgical oncologic safety margin to decrease with 1-2 cm and the abdominoperineal resection to be able to be performed in tumors situated at 4 cm from the anal verge. This modification of the treatment strategy increased the use of low, ultra low and colo-anal anastomoses.

Pancreaticojejunostomy - Risk Anastomosis after Cephalic Pancreaticoduodenectomy.

Introduction: The authors bring to attention pancreaticojejunalanastomosis (PJA) performed after cephalic pancreaticoduodenectomy(CPD). This type of anastomosis is renowned forits high risk of complications. Among these complications, pancreatic fistula (PF) is distinguishable due to a significant frequency, averaging 10%.

"Difficult" Colorectal Polyps - Therapeutic Approach.

Introduction: Endoscopic polypectomy is the gold standard in the treatment of colorectal polyps. The importance of polypectomy rests primarily on the fact that polyp-type lesions present a high risk of malignant degeneration, colorectal polyps being able, if left unattended therapeutically, to generate a colorectal cancer (CRC) - a lesion with a far more negative prognosis. Although preferable, endoscopic polypectomy of colorectal polyps is not always possible, multiple factors generating difficulties in performing this therapeutic measure.
