RESUMO
BACKGROUND: Delirium is a common and serious complication in elderly patients undergoing major abdominal surgery, with significant adverse outcomes. Successful strategies or therapies to reduce the incidence of delirium are scarce. The objective of this study was to assess the role of prehabilitation in reducing the incidence of delirium in elderly patients. METHODS: A single-center uncontrolled before-and-after study was conducted, including patients aged 70 years or older who underwent elective abdominal surgery for colorectal carcinoma or an abdominal aortic aneurysm between January 2013 and October 2015 (control group) and between November 2015 and June 2018 (prehabilitation group). The prehabilitation group received interventions to improve patients' physical health, nutritional status, factors of frailty and preoperative anaemia prior to surgery. The primary outcome was incidence of delirium, diagnosed with the DSM-V criteria or the confusion assessment method. Secondary outcomes were additional complications, length of stay, unplanned ICU admission, length of ICU stay, readmission rate, institutionalization, and in-hospital or 30-day mortality. RESULT: A total of 360 control patients and 267 prehabilitation patients were included in the final analysis. The mean number of prehabilitation days was 39 days. The prehabilitation group had a higher burden of comorbidities and was more physically and visually impaired at baseline. At adjusted logistic regression analysis, delirium incidence was reduced significantly from 11.7 to 8.2% (OR 0.56; 95% CI 0.32-0.98; P = 0.043). No statistically significant effects were seen on secondary outcomes. CONCLUSION: Current prehabilitation program is feasible and safe, and can reduce delirium incidence in elderly patients undergoing elective major abdominal surgery. This program merits further evaluation. TRIAL REGISTRATION: Dutch Trial Registration, NTR5932.

BACKGROUND: Postoperative delirium is a common and serious adverse event in the elderly patient and is associated with significant morbidity and mortality. It is of great importance to identify patients at risk for delirium, in order to focus preventive strategies. The aim of this article is to systematically review current available literature on pre-operative risk factors for delirium after vascular surgery. METHODS: A systematic literature search was conducted using PubMed and EMBASE, using the MeSH terms and key words "delirium", "surgery" and "risk factor". Studies were retained for review after meeting strict inclusion criteria that included only prospective studies evaluating risk factors for delirium in patients who had elective vascular surgery. Diagnosis of delirium needed to be confirmed using the Diagnostic and Statistical Manual of Mental Disorders (DSM) or ICD-10. RESULTS: Fifteen articles were selected for inclusion, incidence of delirium across the studies ranged from 5% to 39%. Many factors have been associated with increased risk of delirium, including age, cognitive impairment, comorbidity, depression, smoking, alcohol, visual and hearing impairment, ASA-score, biochemical abnormalities, operative strategies and blood loss. CONCLUSIONS: Delirium is a common complication after elective vascular surgery in elderly. The highest delirium incidence was observed after open aortic surgery as well as after surgery for critical limb ischemia. A picture starts to form of which predisposing factors lead to increased risk of delirium. The leading risk factors consistently identified in this systematic review were advanced age and cognitive impairment. Multi-disciplinary specialist-led interventions in the preoperative phase could decrease incidence and severity of delirium and should be focused on identified high-risk patients.

A patient with known asbestosis and a recent chorea was admitted for analysis of increasing disturbances of mobility, memory and social unacceptable behavior. At physical examination only minor neurological signs were seen. Additional investigations (among others CT-brain and PET-scan) suggested early M. Alzheimer. Two months later, the patient was readmitted with pneumonia and delirium. A literature review revealed some reports of vague neurological symptoms. An association between asbestos and the disorders in this patient was considered unlikely . An approach is proposed for asbestosis patients with vague neurological and/or psychiatric symptoms.

BACKGROUND: The optimum method for inguinal hernia repair has not yet been determined. The recurrence rate for non-mesh methods varies between 0.2 and 33 per cent. The value of tension-free repair with prosthetic mesh remains to be confirmed. The aim of this study was to compare mesh and non-mesh suture repair of primary inguinal hernias with respect to clinical outcome, quality of life and cost in a multicentre randomized trial in general hospitals. METHODS: Between September 1993 and January 1996, all patients scheduled for repair of a unilateral primary inguinal hernia were randomized to non-mesh or mesh repair. The patients were followed up at 1 week and at 1, 6, 12, 18, 24 and 36 months. Clinical outcome, quality of life and costs were registered. RESULTS: Three hundred patients were randomized of whom 11 were excluded. Three-year recurrence rates differed significantly: 7 per cent for non-mesh repair (n = 143) and 1 per cent for mesh repair (n = 146) (P = 0.009). There were no differences in clinical variables, quality of life and costs. CONCLUSION: Mesh repair of primary inguinal hernia repair is superior to non-mesh repair with regard to hernia recurrence and is cost-effective. Postoperative complications, pain and quality of life did not differ between groups.

BACKGROUND: Incisional hernia is an important complication of abdominal surgery. Procedures for the repair of these hernias with sutures and with mesh have been reported, but there is no consensus about which type of procedure is best. METHODS: Between March 1992 and February 1998, we performed a multicenter trial in which we randomly assigned to suture repair or mesh repair 200 patients who were scheduled to undergo repair of a primary hernia or a first recurrence of hernia at the site of a vertical midline incision of the abdomen of less than 6 cm in length or width. The patients were followed up by physical examination at 1, 6, 12, 18, 24, and 36 months. Recurrence rates and potential risk factors for recurrent incisional hernia were analyzed with the use of life-table methods. RESULTS: Among the 154 patients with primary hernias and the 27 patients with first-time recurrent hernias who were eligible for the study, 56 had recurrences during the follow-up period. The three-year cumulative rates of recurrence among patients who had suture repair and those who had mesh repair were 43 percent and 24 percent, respectively, with repair of a primary hernia (P=0.02; difference, 19 percentage points; 95 percent confidence interval, 3 to 35 percentage points). The recurrence rates were 58 percent and 20 percent with repair of a first recurrence of hernia (P=0.10; difference, 38 percentage points; 95 percent confidence interval, -1 to 78 percentage points). The risk factors for recurrence were suture repair, infection, prostatism (in men), and previous surgery for abdominal aortic aneurysm. The size of the hernia did not affect the rate of recurrence. CONCLUSIONS: Among patients with midline abdominal incisional hernias, mesh repair is superior to suture repair with regard to the recurrence of hernia, regardless of the size of the hernia.

OBJECTIVE: To obtain an impression of the tissue donor potential in Dutch nursing homes and of the knowledge and the attitude of nursing home physicians and nursing home directors with regard to tissue donation. Also, to gain insight into the problems associated with activating tissue donation in nursing homes. DESIGN: Descriptive and inventory. METHOD: The donor potential was calculated from data derived from the National nursing home registration system (SIVIS) in 1995. A questionnaire on the knowledge and attitude with regard to organ/tissue donation was sent to 400 randomly chosen nursing home physicians and all 323 nursing home directors. RESULTS: Out of the 10,619 somatic patients deceased in nursing homes in 1995, 2670 (25%) would have been suitable for skin and/or cornea donation. Other patients had comorbidity regarded as a contraindication for donorship or were over 80 years of age. Of the 9771 deceased psychogeriatric patients, virtually none were suitable as tissue donors. The response to the questionnaire was 55% among nursing home physicians and 66% among nursing home directors. Both groups showed inadequate knowledge with regard to tissue donation. Most nursing home physicians (85%) took a neutral position on tissue donation in nursing homes; most directors (88%) would support tissue donation in their nursing home. The two problems that were mentioned most in having a negative influence on tissue donation in nursing homes, were: the lack of knowledge of physicians and the refusal of donation by patients. CONCLUSION: Some 2700 somatic nursing home patients annually would be suitable for tissue donation. Determination of their willingness is necessary. Activating of tissue donation in nursing homes requires solving of the lack of knowledge.

OBJECTIVE: The authors determined the prevalence of foreign body granulomas in intra-abdominal adhesions in patients with a history of abdominal surgery. PATIENTS AND METHODS: In a cross-sectional, multicenter, multinational study, adult patients with a history of one or more previous abdominal operations and scheduled for laparotomy between 1991 and 1993 were examined during surgery. Patients in whom adhesions were present were selected for study. Quantity, distribution, and quality of adhesions were scored, and adhesion samples were taken for histologic examination. RESULTS: In 448 studied patients, the adhesions were most frequently attached to the omentum (68%) and the small bowel (67%). The amount of adhesions was significantly smaller in patients with a history of only one minor operation or one major operation, compared with those with multiple laparotomies (p < 0.001). Significantly more adhesions were found in patients with a history of adhesions at previous laparotomy (p < 0.001), with presence of abdominal abscess, hematoma, and intestinal leakage as complications after former surgery (p = 0.01, p = 0.002, and p < 0.001, respectively), and with a history of an unoperated inflammatory process (p = 0.04). Granulomas were found in 26% of all patients. Suture granulomas were found in 25% of the patients. Starch granulomas were present in 5% of the operated patients whose surgeons wore starch-containing gloves. When suture granulomas were present, the median interval between the present and the most recent previous laparotomy was 13 months. When suture granulomas were absent, this interval was significantly longer--i.e., 30 months (p = 0.002). The percentage of patients with suture granulomas decreased gradually from 37% if the previous laparotomy had occurred up to 6 months before the present operation, to 18% if the previous laparotomy had occurred more than 2 years ago (p < 0.001). CONCLUSIONS: The number of adhesions found at laparotomy was significantly larger in patients with a history of multiple laparotomies, unoperated intra-abdominal inflammatory disease, and previous postoperative intra-abdominal complications, and when adhesions were already present at previous laparotomy. In recent adhesions, suture granulomas occurred in a large percentage. This suggests that the intra-abdominal presence of foreign material is an important cause of adhesion formation. Therefore intra-abdominal contamination with foreign material should be minimized.
