Septimiu, Alexandru C.; Moldovan, Cosmin A.; and Ungureanu, Florin D. (2017) "The prevalence of high dysplastic colonic adenomatous polyps in a 3 year endoscopic retrospective study from a single clinical center," Abstract Introduction: Many colon neoplastic tumors come from the malignancy of adenomatous polyps (70%-90%) that were not timely diagnosed in order to be resected. Materials and Methods: We conducted a retrospective study regarding the incidence of adenomatous polyps during 1.000 consecutive colonoscopies performed in our Upper and Lower Digestive Endoscopy Laboratory during a three-year period.Results: During these colonoscopies, some targeted polyps were biopsied or completely removed and the samples had been sent to a complete anatomopathological examination. Taking into consideration the results, the polyps were classified after the histological type and the form of dysplasia, in order to determine the polyp forms that present a high risk of malignancy. Conclusion:Given the rather high frequency of malignant polyps discovered during our study, we highly recommend colonoscopy as a method of choice for routine monitoring of selected cases.

AC. A proposed therapeutic algorithm for colorectal cancer prevention, based on endoscopic polypectomies in patients with multiple colonic polyps.

Aim: A retrospective analysis was made of results obtained in 169 patients with axial transomphalic external biliary drainage, operated between 1984 and 1998. However, the authors’ experience with this method covers a total of 773 cases in which this type of drainage was used between 1966 and 1998. Method: The technique is described in detail. The use of the omphalic ligament provides a completely extraperitoneal trajectory for biliary drainage tubing inserted between the two peritoneal layers of the ligament. Results: Postoperative mortality and morbidity in the patients presented here were not related to the drainage procedure, but were related to the background illness, associated disturbances and the surgical procedures applied. Axial transomphalic biliary drainage has many indisputable advantages in comparison with other types of external biliary drainage. Indications and counterindications of the method are summarized. Conclusion: The technique is especially valuable because it protects biliary-digestive anastomoses and common biliary duct sutures, facilitating implantation of prostheses and reconstruction of the main biliary pathway, as well as benign and malignant stenoses.

An evidence based guide to a safe intraoperative approach of avoiding iatrogenic lesions during difficult laparoscopic cholecystectomies Cover Page FootnoteThis scientific material is part of a lager retrospective study of a PhD thesis, currently under development by Moldovan Cosmin, M.D., Ph. D. student at the Carol Davila University of Medicine and Pharmacy, Bucharest, with Prof. Vladimir Beliș. M.D., PhD., as thesis coordinator. The thesis has the following title: "Contributions to the forensic and legal study regarding the consequences of the iatrogenic lesions of the main biliary pathways occurred during the laparoscopic approach of hepato-biliary surgery". All authors have read and approved the final manuscript and also declare no conflicts of interest. Abstract Introduction: Although there are many sources for iatrogenic lesions during laparoscopic cholecystectomy, only a few stand out as being one of the most difficult to predict due to their nature of being very hard to diagnose before surgery.Materials and Methods: a short guide of cases with an evidence-based approach to avoid laparoscopic iatrogenic lesions. Results: these cases have been classified and presented into 3 main groups: cases with abnormal arterial layout, cases with heavy alteration of the normal anatomy, and cases with anomalies of the main biliary pathway. Conclusions: while not a complete guide covering all aspects of intraoperative traps during laparoscopic cholecystectomy, this series of cases points out some dangerous situations and some simple solutions to avoid those fiercely iatrogenic lesions of the ductal and vascular landmarks associated with an otherwise simple surgical intervention that has become the golden standard of the gallbladder lithiasic pathology.
