Article: Radiofrequency-assisted liver resection: short-term results in a single institution.
[show abstract] [hide abstract]
ABSTRACT: Objectives: The main goal of the study was to evaluate the effectiveness and safety of radiofrequency-assisted liver resection.Background: Liver resection is the "gold standard" for patients with resectable liver tumors. In the past years, the role of radiofrequency in liver surgery has been expanded from simple tumor ablation to its use in the technique of radiofrequency-assisted liver resection.Methods: Patients with primary or secondary liver tumors, who underwent radiofrequency-assisted liver resection have been included into the prospective study. The acquired data underwent statistical analysis and were compared with the published results of liver resections.Results: Between January 1, 2007 and September 30, 2009, 53 patients underwent radiofrequency-assisted liver resection. Seventy-six tumours were resected with the mean diameter of 38±19 mm. Mean peroperative blood loss was 170.8±285.4 mL and transfusions were needed postoperatively in 9.4 % cases. The mean hospital stay was 10.6±7.2 days. Postoperative complications were noted in 16.9 % patients; postoperative mortality was 1.9 %. Conclusion: The radiofrequency-assisted liver resection represents a safe and effective way of hepatic parenchyma transaction and to hepatobiliary surgeon it offers a new way of effective transection of liver parenchyma (Tab. 2, Ref. 23). Keywords: radiofrequency, liver tumors, liver resection.Bratislavske lekarske listy 01/2013; 114(1):19-22. · 0.40 Impact Factor -
Article: [Is age a risk factor for laparoscopic colorectal surgery?].
[show abstract] [hide abstract]
ABSTRACT: The aims of this study were to evaluate the results of laparoscopic colorectal surgery in elderly patients and compare them with the results of open procedures. An analysis of a prospectively collected database of 705 patients who underwent in the period between January 2001 and December 2006 elective laparoscopic (LAC) or open (OC) colorectal surgery was performed. The primary end point was the morbidity rate, which was analysed in relation to the age (≤ 75 years, > 75 years) and operative technique (laparoscopic, open). During the study period, 360 elective laparoscopic and 345 elective open colorectal operations were performed. 140 patients (20%) were older than 75 years (geriatrics), 60 of whom underwent laparoscopic and 80 open surgery. Both groups of patients (laparoscopic vs. open) were comparable in basic parameters. Mean operative time for laparoscopic colorectal resections was not longer (LAC 141 ± 46 min vs. OC 137 ± 57 min, n. s.); even in cases of simple stoma formation it was significantly shorter (LAC 42 ± 19 min vs. OC 78 ± 32 min, p = 0.004). In the group of younger patients (≤ 75 years) the open approach was associated with a statistically significant increase of postoperative morbidity (LAC 26% vs. OC 34%, p = 0.039). In the group of geriatric patients (> 75 years) the open approach was associated with a significantly high incidence of postoperative morbidity (LAC 27% vs. OC 48%, p = 0.012) too. In the laparoscopically operated patients, the morbidity rate did not differ in both age groups (older than 75 years 27% vs. younger than 75 years 26%, n. s.). Conversely, open procedures in elderly patients were associated with a significant increase of postoperative complications (morbidity) compared to younger patients (older than 75 years 48% vs. younger than 75 years 34%, p = 0.033). On account of the lower incidence of post-operative complications, the laparoscopic approach should be indicated in colorectal surgery for geriatric patients.Zentralblatt für Chirurgie 12/2010; 136(3):264-8. · 1.02 Impact Factor -

Article: Virtual colonoscopy: a new promising technique.
[show abstract] [hide abstract]
ABSTRACT: Virtual colonoscopy is less invasive than conventional colonoscopy and does not require a conscious sedation. Virtual colonoscopy using the abdominal spiral computed tomography scanning allows a total colonic evaluation with minimal invasiveness. We studied 48 patients with a virtual colonoscopy using oral iodinated contrast. Colonic lavage was achieved with an oral polyethylene glycols preparation. We examined patients who had refused a colonoscopic examinations, or patients with a stenotic processes, in which it was not possible to examine the proximal colon using standard methods. Our indications for CT virtual colonoscopy were following: firstly, when colonic examination by other methods (colonoscopy, barium enema) failed or was not possible, and secondly, to exclude tumour duplicity in cases with an already verified colon tumour. 26 patients underwent a virtual colonoscopy examination based on the first indication, and 22 patients based on the second indication. In summary, our results show that virtual colonoscopy is a promising method in detecting individuals with significant colorectal lesions. The aim of the present study was to assess the ability of virtual colonoscopy using oral contrast to detect patients with colorectal lesions who need a colonoscopy (Tab. 2, Fig. 3, Ref. 4).

Article: Familial adenomatous polyposis as a precancerosis of colon cancer.
[show abstract] [hide abstract]
ABSTRACT: Familial adenomatous polyposis is a genetic disorder caused by mutations of the adenomatous polyposis coli gene. This gene is localized on chromosome 5q21. The incidence of the disease is 1/7000-8000. Surgery has an important role in the management of familial adenomatous polyposis. In the absence of prophylactic colectomy, death from colom cancer will occur in virtually all of familial adenomatous polyposiscases by age 50, with 37% affected by colon cancer by age 37.

Article: Long-term results of laparoscopic versus open surgery for nonmetastatic colorectal cancer.
[show abstract] [hide abstract]
ABSTRACT: Laparoscopic surgery for colon cancer has been proven safe, but controversy continues over implementation of laparoscopic technique for rectal cancer. The aim of this study was to compare the long-term outcomes of laparoscopically assisted and open surgery for nonmetastatic colorectal cancer. From January 2001 to December 2006 all patients with nonmetastatic adenocarcinoma of the colon and rectum were considered for inclusion in this prospective non-randomised trial. The primary endpoint was overall survival, disease free survival and recurrence rate. Analysis was by intention to treat. A total of 365 resections were performed for nonmetastatic adenocarcinoma of the colon and rectum during the study period. Of those resections, 220 were colonic and 145 were rectal. In the patients with colon cancer 119 (54.1%) were operated laparoscopically and 101 (45.9%) by open surgery, in the patients with rectal cancer 75 (51.7%) were treated by laparoscopy and 70 (48.3%) by open technique. No statistically significant difference was found between the laparoscopic and open group regarding 5-year overall survival (p = 0.17 for colon cancer, p = 0.60 for rectal cancer), 5-year disease free survival (p = 0.25 for colon cancer, p = 0.81 for rectal cancer) and overall recurrence (p = 0.78 for colon cancer, p = 0.79 for rectal cancer). With respect to the tumor stage, in rectal cancer the probability of 5-year disease free survival was significantly higher in the laparoscopic group in stage III (p = 0.03). Laparoscopic surgery for colorectal cancer is an oncologically safe procedure that is associated with a survival and recurrence rate equal to open surgery.Acta chirurgica Belgica 112(2):139-47. · 0.43 Impact Factor
