[Proximal femur fractures in the elderly in The Netherlands during the period 1991-2004: incidence, mortality, length of hospital stay and an estimate of the care capacity needed in the future].

OBJECTIVE: To assess the incidence of operations for neck and pertrochanteric femur fractures during the last 15 years and to estimate the future demand for such operations in The Netherlands. DESIGN: Retrospective. METHOD: For the years 1991, 1995, 2000 and 2004, the following anonymised data were collected in the National Medical Registry of Prismant for all patients admitted to Dutch hospitals for a hip fracture: age-group, gender, length of pre- and postoperative hospital stay, destination after discharge and hospital mortality. These data were related to demographic data for the Dutch population from Statistics Netherlands (CBCS) and to estimates for the Dutch population in the future from Primos Prognostic Data. RESULTS: The average absolute increase in the period 1991-2004 was linear, with 230 fractures per year. Women were operated for a hip fracture 1.5-2 times as often as men in the same age range. The age-specific incidence remained constant over the years but the absolute number of elderly persons per age group increased. The average length of pre- and postoperative hospital stay was reduced by half during the period under investigation. The postoperative hospital mortality decreased from 8.1% in 1991 to 5.6% in 2004, and was 1.5 times as high for men aged 70 years or over as for women of the same age group. In 2004 as compared to 1991, 2.5 times as many patients were discharged to a nursing home. In view of the increasing age of the population, the total number of operated hip fractures can be expected to be 20,200 in the year 2010 and 23,900 in the year 2020. CONCLUSION: In the period 1991-2004 there was an annual increase of 230 operations for proximal femur fractures that was closely related to the ageing of the Dutch population. During the years under investigation, the incidence in the same age range was higher in women, but men had a higher hospital mortality. It is estimated that the decreasing hospital mortality and the decrease in the length of hospital stay will increase the need for nursing-home care for this category of patients.

[Symptomatic gallstone disease: an indication for surgery].

Three patients, men in the ages of 58, 66 and 56 years, respectively, had experienced 'warning colics' a considerable time before gallstone complications or severe recurrent colic. Ultrasonographically proven gallstones had not led to cholecystectomy. The 58-year-old man died of sepsis due to infected pancreatic necrosis; the other men underwent laparoscopic cholecystectomy, after which they recovered fully. Approximately 10-5% of the adult Dutch population have gallstones, but only 10% will develop symptoms. The annual risk for developing complicated gallstone disease is 1-2% in asymptomatic gallstone carriers. Of patients admitted with complicated gallstone disease, 58% have had prior 'warning colics'. Complicated gallstone disease can be prevented by timely treatment after recognition of warning colics. Cholecystectomy is indicated in patients with intermittent upper-abdominal pain and proven gallstones or sludge.

What is next in inguinal hernia surgery?

Traditionally, the inguinal hernia repair is performed through an incision in the groin. Different kinds of operations are suggested as best repairs by using the patient's own tissue, or use of prosthetic mesh to reinforce the abdominal wall. The advent of the laparoscopic repair that also uses prosthetic mesh, made it even more complex to determine the best repair. Using the Evidence Based Medicine (EBM) principles, endpoints of the treatment are not only based on recurrence rates, but also on complications, patient satisfaction, convalescence, and costs. Several meta-analyses concluded that use of mesh is superior to the non-mesh operations. More difficult to determine is which mesh repair, open or laparoscopically, is the best. The laparoscopic repair is difficult and less suitable for general practice, but the open-mesh repair results in a higher percentage of chronic postoperative pain. Further research should be focused on making the laparoscopic repair less complicated, and development of new meshes for open surgery that reduce the amount of persistent postoperative pain.

Time-action analysis of instrument positioners in laparoscopic cholecystectomy.

BACKGROUND: Instrument positioners can position and lock a laparoscopic instrument. This study uses time-action analysis to evaluate objectively whether IPs can substitute for a surgical assistant efficiently and safely. METHODS: In four hospitals, 78 laparoscopic cholecystectomies were randomly assisted by a surgical assistant or an instrument positioner (AESOP and PASSIST) The efficiency and safety of laparoscopic cholecystectomies were analyzed with respect to time, number and type of actions, positioning accuracy, and peroperative complications. A questionnaire evaluated the difficulties for each operation and the comfort of instrument positioner use. RESULTS: The PASSIST and AESOP were able to replace the surgical assistant during laparoscopic cholecystectomies without significantly changing either the efficiency or the safety of the operation. The questionnaire showed that the surgeons preferred to operate with an instrument positioner. CONCLUSION: This study assessed objectively that instrument positioners can substitute for a surgical assistant efficiently and safely in elective laparoscopic cholecystectomies.
