The use of totally implantable prolonged venous access devices (TIPVAD) in chemotherapy for oncological patients is now consolidated practice, whereas the choice between surgical cutdown and the percutaneous technique is still a controversial matter. The aim of this study was to retrospectively evaluate the validity and safety of the surgical approach by comparison with percutaneous techniques. Over a period of 17 months, 106 patients (mainly oncological cases) underwent surgical cutdown for TIPVAD placement in the cephalic vein. ⋯ We observed a lower incidence of pneumothorax, 2 cases of malfunction due to kinking, and no catheter fractures, while management complications were similar to the findings in the literature. In expert hands, the surgical approach is a fast, safe technique with a lower rate of intraoperative complications than the percutaneous approach and less discomfort for the patient. Adequate training of medical and paramedical staff is the most important factor in making TIPVAD reliable and safe in the long term.

The aim of this retrospective study was to assess the feasibility, safety and efficacy of the laparoscopic approach in the management of perforated peptic ulcers. From January 1997 to December 2002, all patients referred to our community hospital for abdominal surgical emergencies were routinely managed by laparoscopic surgery. A review was carried out on 39 consecutive patients suffering from perforated peptic ulcers with or without generalised peritonitis. ⋯ The mean operative time was 77 minutes (range: 40-120) and the mean hospital stay 9 days (range: 3-22). Laparoscopic repair of perforated ulcers is technically feasible but requires sound experience in laparoscopic abdominal emergencies. This study shows that the mini-invasive procedure is safe and effective, offering a valid alternative to traditional laparotomy.

The natural history of diverticulosis is worthy of note for its acute, sometimes recurrent, attacks of diverticulitis and the significant risk of serious complications, such as abscess, fistula and peritonitis. Most mild attacks of diverticulitis respond well to medical therapy while surgical treatment is indicated in the complicated forms of the disease. We evaluate the results of treatment of complicated acute diverticulitis by laparoscopic colorrhaphy, irrigation and drainage as a minimal surgical approach in 7 selected patients. ⋯ No perioperative morbidity or mortality was observed. All patients were discharged with no further re-operation. The technique could be considered a valid alternative for the management of complicated and perforated diverticulitis in selected patients.

Liver transplantation for malignancies still remains a controversial issue. There is concern for tumour recurrence, poor results and waste of organs, which in the sitting of organ shortage would penalize patients with non-malignant disease. Many centers worldwide perform liver transplantation (OLT) for hepatocellular (HCC) carcinoma associated with liver cirrhosis; the results in these cases are similar to those of patients transplanted for other indications. ⋯ There is no evidence that OLT is beneficial for non-HCC tumours. Hopefully for the next future new adjuvant and neoadjuvant therapies combined with OLT would provide improved survival. Nevertheless, long-term survivors continue to be reported suggesting that OLT may be beneficial in individual selected cases with non-HCC tumour.

The use of virtual reality simulation is currently being proposed within programs of postgraduate surgical education. The simple tasks that make up an operative procedure can be repeatedly performed until satisfactory execution is achieved, and the errors can be corrected by means of objective assessment. ⋯ A significant reduction in operative time and errors was noted in several tasks (navigation, clipping, etc.). Although the transfer of technical skills to the operating room environment remains to be demonstrated, our research shows that this type of teaching is applicable to undergraduate medical students and in future may become a useful tool for selecting individuals for surgical residency programs.
