[OUR RESULTS IN LAPAROSCOPIC-ASSISTED PLACEMENT OF PERITONEAL DIALYSIS CATHETERS: TEN-YEAR EXPERIENCE]. / NASE 11-GODISNJE ISKUSTVO U POSTAVLJANJU KATETERA ZA PERITONEJSKU DIJALIZU LAPAROSKOPSKOM TEHNIKOM.

The aim was to analyze our results and complications in laparoscopic-assisted placement of the Tenckhoff catheter for peritoneal dialysis in comparison with results reported in the literature. Fifty patients were included in this retrospective analysis. From January 2000 to November 2010, they underwent laparoscopic-assisted placement of catheter for peritonea dialysis at the University Department of Surgery, Rijeka University Hospital Center. The results of this approach, early and late postoperative complications, conversions to open technique, and reoperation rate were analyzed. The complications that occurred within the first 4 weeks were considered as early complications. In 23 patients, 29 complications were recorded. There were 18 early complications, of which 2 acute peritonitis, 2 ileus, 4 bleeding, 4 catheter infection, 3 fluid leakage, 2 catheter malpositioning and 1 genital edema. There were 11 late complications, of which 5 acute peritonitis, 1 recurrent peritonitis, 1 bleeding, 1 catheter infection, 1 catheter malpositioning, 1 fluid leakage and 1 port site hernia. There were no deaths after surgery or any complications disabling the implementation of peritonea dialysis. In patients with end-stage renal disease, laparoscopic-assisted placement of catheter for peritoneal dialysis is a safe and appropriate method of treatment

Outcome evaluation of 10,317 laparoscopic cholecystectomies: a 17-year experience at a single center.

BACKGROUND/AIMS: This study is an analysis of the large series of laparoscopic cholecystectomies and compare our results with those reported in the literature concerning complications. METHODOLOGY: From December 1993 to September 2010, 10,317 patients with gallstone disease underwent laparoscopic cholecystectomy. Previously operated patients were also included in the study. We analyzed the successfulness of the results, intraoperative and postoperative complications, conversions in open cholecystectomy, mortality and reoperation rate. RESULTS: We registered 23.28% complications. Intraoperative complications were bleeding in 9.84%, gallbladder perforation in 8.63%, stone loss in 1.37%, common bile duct injury in 0.24% and injury of intraabdominal organs in 0.07% of cases. Postoperative complications were bleeding in 1.12%, wound infection in 0.59%, bile leakage in 0.5%, incisional umbilical hernias in 0.37%, subhepatal collection in 0.33%, residual gallstones in choledocus in 0.09%, urine retention in 0.08% and biliary peritonitis in 0.01% of patients. Conversion to open cholecystectomy was necessary in 2.13%. Reoperation was performed in 0.27%. The mortality rate was 0.019%. CONCLUSIONS: Our results on large number of patients are similar to other series in the newer literature but the rate of complications should be decreased. The incidence of complications decreases with growing laparoscopic experience.

Evaluation of adjuvant chemotherapy in patients with colorectal cancer in Primorsko-Goranska and Istarska County--a twenty years retrospective study.

Colorectal cancer is the second most common malignant disease in developed countries, with about one million new cases worldwide every year, accompanied with high mortality rate. We examined the survival rate and recurrence (occurrence of distant metastases and/or local recurrence) of patients with colorectal cancer in Primorsko-Goranska and Istarska County who received adjuvant chemotherapy, compared to those who did not in the period since 1980. until 1999. This study involves 483 patients with colorectal cancer stages II and III of Primorsko-Goranska and Istarska County, which were underwent curative resections of colorectal cancer at the Clinical Hospital Centre Rijeka, and then treated with chemotherapy (288) or without Chemotherapy (195). We analyzed the five year survival rate and the recurrence of malignant disease in the adjuvant treatment group in comparison with not treated group with chemotherapy, depending on the stage of disease, degree of histological differentiation, patient age and location of cancer (colon or rectum). After follow-up of 60 months died 44.79% (129/288) of patients who received chemotherapy and 53.33% (104/195) of patients who did not receive chemotherapy. The relative risk of death (from any cause) in chemotherapy-treated group versus the group without chemotherapy was 0.82 (p < 0.008). Recurrence of malignant disease in the chemotherapy group was 38.54% (111/288), and in the group without chemotherapy was 46.15% (90/195). The relative risk of recurrence of malignant disease in the chemotherapy group versus the group without chemotherapy was 0.78 (p < 0.001). There was no difference in treatment efficacy regard to the localization of the tumor, but there were differences in efficiency with respect to disease stage, grade and age. Chemotherapy with 5-fluorouracil and leukovorin ameliorate the survival and reduces recurrence and distant metastases in patients with colorectal cancer stages II and III.

Perforin expression in peripheral blood lymphatic cells of patients subjected to laparoscopic or open cholecystectomy.

Perforin-(P-) related characteristics of cytotoxic T lymphocytes and natural killer cells were investigated in peripheral blood of patients subjected to open (OC; n = 23) or laparoscopic cholecystectomy (LC; n = 21) and healthy controls (n = 20). Blood samples were obtained preoperatively and 24 hours after the surgeries, and the data were correlated with the intensity of cholestasis and concomitant inflammation, determined by functional hepatic tests. Postoperative differences were found to be minimal: OC decreased only the percentage of CD56(+) cells, while LC decreased the fraction of CD8(+)P(+) cells and augmented the mean fluorescence intensity of P in CD56 cells. Patients elected for OC had, however, higher preoperative numbers of total P(+), CD3(+)P(+), and CD4(+)P(+) cells than patients elected for LC and healthy controls, while both groups of patients, preoperatively, had lower fraction of CD16(+)P(+) and CD56(+)P(+) cells. These changes were in high correlation with blood concentrations of CRP, AP, and ALT, emphasizing the link between the preoperative cholestasis and inflammation and P-dependent cytotoxic mechanisms.

[Harmonic scalpel in laparoscopic surgery]. / Primjena visokofrekventno titrajuceg rezaca u laparoskopskoj kirurgiji.

Harmonic scalpel for the tissue cutting and coagulating is a replacement for the high frequency current, which can be connected with diverse complications. The principle is transforming of the electric power into mechanical longitudinal movement of the working part of the instrument, by piezoelectrical transducer situated in the hand piece. Between October 2000 and June 2001, one hundred and three patients were operated using harmonic scalpel. The average age was 50.2 years. Laparoscopic cholecystectomy, appendectomy and abdominal cyste fenestration was performed in 86, 12 and 4 patients respectively. In one patient laparoscopic cholecystectomy and abdominal cyste fenestration were done during the same operation. The average hospital stay was 2.8 days. Laparoscopic cholecystectomy, appendectomy and cyst fenestration using the harmonic scalpel are safe and successful operations, with good results and advantages of the minimally invasive surgery.
