Methods: Laparoscopic SPA-IPOM is done through a 10 mm trocar with one 10 mm instrument that has 5 mm optical lens and 5 mm channel for grasper. After inserting 10 mm trocar at umbilicus using semi-open technique, intraperitoneal anatomical landmark of inguinal her-nia is identified. A 10 × 15 cm pre-tied bioresorbable composite mesh is then placed to cover hernia defect and all three potential area of indirect, direct and femoral hernia. Using Endoclose? needle, each pair of pre-tied sutures is retrieved percutaneously through a needle wound and extracorporeal tied with knot in subcutaneous space. After the upper half of mesh is sutured to the posterior surface of abdominal wall, the lower half of mesh is fixed by hernia tacker to Symphysis Pubis, Cooper Ligament and Iliopubic tract. Re-sults: Three men, average 48 year olds were operated by laparoscopic 10 mm SPA-IPOM for bilateral in-guinal hernia repair using bioresorbable composite mesh. Average operative time was 36 minutes. No imme-diate complication. All patients were discharge on the 2nd post-operative day and average 6 months follow up has no recurrence. Conclusions: Laparoscopic SPA-IPOM is an optional operation and is much easier to be performed. Benefits include operative time saving, cosmesis, early discharge and early return to work. Bio-resorbable composite mesh prevents bowel adhesion, however, is much more expensive. Long term follow up study for complications and recurrence is needed.展开更多

In this study, we examined the clinical course of LC patients with subcutaneously implanted CV-ports from the time of receiving chemotherapy to the endpoint of cancer. Materials and Methods: We retrospectively reviewed the clinical data and treatment history of LC patients with subcutaneously implanted CV-ports between June 2008 and November 2013 using clinical records and a pharmacy database. Results: Of the 132 LC patients with subcutaneously implanted CV-ports, 79 (59.8%) had CV-ports for CC (the CC group) and 53 (40.2%) had CV-ports for PC (the PC group). After CV-port implantation, LC patients in the CC group received a median of two regimens with a median of 6 cycles. The median survival time of patients in the CC and PC groups was 457 and 44 days, respectively. In the CC group, the median survival time of small cell and non-small cell LC patients was 342 (95% confidence interval, 235 - 627) and 563 (95% confidence interval, 368 - 728) days, respectively. Nine patients (6.8%) had their CV-ports removed due to complications. Forty (30.3%) of the 132 enrolled patients were referred for at-home PC. The at-home death rate observed among these 40 patients was 30.0% (N = 12). Conclusion: CV-ports may contribute to seamless oncological care.展开更多

Cephalic vein cutdown method has fewer complications but has higher failure rates. We present a method to decrease the failure rates. Methods: We use the continuously injection with diluted heparin solution via catheter while introducing the TIAP catheter into the cephalic vein. Results: From January 2005 to January 2009, 20 patients were performed. This method was successfully applied in 11 patients with no complications. The other 9 patients was unsuccessfully and further underwent guidewire assisted. Conclusions: Continuously injection with diluted heparin solution via catheter while inserting TIAP catheter into the cephalic vein is safe and simple. It could be used for difficulties of insertion of TIAP and increased the successful rates of cephalic vein cut-down method.展开更多

Methods: We conducted a retrospective review of total 163 lung cancer patients who underwent implantations of a central venous access port for chemotherapy. 95 patients received the ports by the femoral vein blind-puncture technique and 68patients had the port implanted via the subclavian vein blind-puncture technique. The initial success rate of port implantation and the frequency of occurrence of complications were calculated. Results: The primary success rate of venous port implantation was 93.7% for femoral approach and 88.2% for the subclavian approach respectively (p < 0.05). Intraoperative complications developed in two patients (2.1%) in the femoral approach group and in five patients (7.4%) in the subclavian approach group. Although a higher intraoperative complication ratio for the subclavian approach was encountered compared to that for the femoral vein approach, there was no statistically significant difference (p = 0.103). Nor was there any statistically significant difference in terms of the occurrence of late complications. Conclusions: Venous access port implantation via the femoral vein approach is safe, and its success rate is very high, with the equal complication rates comparable to the subclavian approach. This approach avoids many of the intraoperative complications. Thus, the femoral vein approach for implanting a venous access port in lung cancer patients should be considered a valid, and safe technique.展开更多
