The epidemiology of inguinal hernia was investigated in a community survey in a neighbourhood of western Jerusalem in 1969-71. The current prevalence rate, excluding operated hernias, was 18 per 100 men aged 25 and over, and the lifetime prevalence, including operated hernias, was 24 per 100. Prevalence rose markedly with age; the lifetime prevalence rate reached 40 per 100 men at the ages of 65-74 and 47 per 100 at 75 and over. The prevalence of hernia was significantly higher in the presence of varicose veins, in men who reported symptoms of prostatic hypertrophy, and, among lean men only, in the presence of haemorrhoids. These associations may reflect the role of increased abdominal pressure. The prevalence of hernia was low in the presence of overweight or adiposity, suggesting that obesity is a protective factor. No significant age-independent associations were found with chronic cough, constipation, physical activity at work, or a number of other variables. Two-thirds of the hernias had not been operated upon. The prevalence of unrepaired hernias rose with age; 13% of all men aged 65-74 and 23% of those aged 75 and over had unoperated groin swellings. One in every five operated hernias showed evidence of recurrence. No significant age-independent associations were found between evidence of occurrence and other characteristics. A comparison of interview responses and examination findings showed that interview data on the presence of hernias were of low validity, mainly because of under-reporting.

In order to give an overview of recent advances in general surgery, it is necessary to define: (i) what is general surgery; (ii) what is recent; and (iii) what constitutes an advance. General surgery appears to have entered an era of conservatism. This is particularly evident in the surgery of breast cancer, peptic ulceration, varicose veins, liver trauma, portal hypertension, upper gastrointestinal bleeding, and hiatal hernia. Controlled clinical trials in surgery have become popular. The following are considered to be advances: parenteral nutrition, suction drainage, control of Gram-negative sepsis, bypass surgery for pathological obesity, and a discriminatory approach to transplant surgery.

Our experience with 101 consecutive T.H.A.'s in 91 patients was examined in an attempt to identify preoperative risk factors for postoperative medical complications, especially pulmonary embolism and thrombophlebitis. Six per cent of patients developed postoperative clinical thrombophlebitis, and 8% a pulmonary embolism. Advancing age and previous venous thrombosis served as predictors for pulmonary embolism and thrombophlebitis, respectively (p less than 0.01), but obesity, venous varicosities, diabetes mellitus, cigarette smoking, previous pulmonary embolism, and length of surgery did not, for either. Fifty per cent of the patients with preoperative abnormal kidney function developed some form of medical complication postoperatively, a significant increase in risk (p less than 0.05) over patients with normal kidney function. We were unable to identify an increase in postoperative atelectasis or pneumonia associated with smoking or obesity in these patients. No consistent decrease in post-operative medical morbidity could be assigned to preoperative medical consultations, suggesting that we have not yet identified all significant risk factors. A thorough preoperative preparation and improvement in intra- and postoperative techniques and management may account for differences found in this study from traditionally held risk factors.

The use of labelled fibrinogen in 106 patients with thromboembolic risk led to the detection of thrombosis of deep veins of lower limbs in 25 patients (23,58%) as compared with a single patient (0,94%) who showed all the clinical signs. The thromboses were identified more frequently (in 60% of the cases) in patients whose age was above 60 years. In 80% of the cases the thromboses were detected in the first 24 h after surgery. Most frequently involved were the veins of the leg (64%), and especially in the IV-th area, corresponding to the upper third of the leg (23,80%). Surgery performed in the pelvic area gave a high percentage of thromboses. Advanced age, the existence of varicose veins, the presence of diabetes, of obesity, as well as previous surgical interventions, increase the risk of thrombosis and of embolies. Due to existing possibilities for an early diagnosis of thromboses in deep veins following surgery, for detecting latent clinical thrombosis, as well as for assessing the evolution of an already formed thrombus, it appears that the test with labelled fibrinogen is a highly useful clinical investigation.

In a group of 300 patients with the diagnosis of lumbar nucleus pulposus prolapse treated surgically the authors found in 4 cases not the expected prolapse but varicose blood vessels surrounding the nerve roots and immobilizing them in adhesions. In another 5 patients vertebral canal varicosities were associated with nucleus pulposus prolapse. None of these cases of vertebral canal varicosities had been diagnosed before operation since the clinical state of these patients was not significantly different from the state of patients with nucleus prolapse and radiculography failed to supply sufficient diagnostic data or suggested presence of small prolapse. An auxiliary diagnostic finding in cases of vertebral canal varices may be frequent association of spinal anomalies (in 3/4 of the observed cases) and obesity (in 2/3 of cases). Surgical decompression of vertebral canal and liberation of roots from adhesions without excision or ligation of varicose veins gave good therapeutic results.

Analysis of data from the Walnut Creek Contraceptive Drug Study showed a significant increase in risk of venous thromboembolic disease in the absence of surgery, trauma, malignancy, pregnancy, and the puerperium for women with a previous history of thromboembolism, hypertension, diabetes, varicose veins, gallbladder disease, and cigarette smoking. Education, marital status, parity, use of noncontraceptive estrogens, and obesity were not associated with an increase in risk of the disease. When only cases of the disease in the absence of all known predisposing causes (idiopathic cases) were analyzed, both oral contraceptive use and smoking remained as independent risk factors; there was no evidence of a positive interaction between them.

Between 1969 and 1971 4,749 antenatal patients were observed. Compared to the tables for ideal weights of the Metropolitan Life Insurance Company Statistical Bureau, 26.76 percent of the patients were above ideal weight and 11.35 percent of the patients were obese. It was found that complications and illnesses during the pregnancy increased progressively with weight groups above the ideal weight. Hypertension was five times as frequent in obese women than normal, edema and proteinuria were common. Pre-eclampsia was more common in the obese. Varicosities occurred much more often in the maternity cases above normal weight and with obesity.

We present the results of a control group of 95 patients who were thoroughly investigated in a prospective, randomized study, where the efficacy of small doses of s.c. heparin and dextran 40 is checked. The 125I-fibrogen test was used in all patients. 1. 35.8% of the patients develop deep vein thrombosis (DVT) during the first post-operative week. More than half of them show bilateral thrombosis. 2. There is no statistically significant difference in the thrombosis incidence between males and females. 3. 47% of the patients over 60 years develop postoperative DVT. Among those younger than 60 years, only 23% have DVT (P less than 0.025). 4. The DVT incidence in surgery of the colon is 58.3%. 5. Surgery for a malignant disease means probably increased risk for DVT (P less than 0.025). 6. More than half of the patients having a previous history of varicose veins develop postoperative DVT (P less than 0.025). 7. Obese patients are statistically seen not more prone to develop DVT than those of normal body build. 8. Immediately after operation 32.4% of DVT are diagnosed, 24 hrs. later 61.8%. 94% of all DVT are diagnosed up to the third postoperative day. 9. With the exeption of one patient, all DVT develop in the calf veins, 3/4 of all abnormal values were measured in the midcalf region.

Obesity, edema in the legs before surgery, a history of deep venous thrombosis, varicose veins, and a diagnosis of osteoarthrosis were associated with an increased risk for postoperative thromboembolism. Selective administration of anticoagulants to high risk but not to low risk patients should result in a reduction in total mortality following surgery. It is therefore suggested that when deciding whether prophylactic anticoagulants should be administered to a patient, consideration should be given to that patient's likelihood of developing fatal pulmonary embolism if the anticoagulant is not given, compared to the potential reduction in his risk for fatal pulmonary embolism and the increase in risk for fatal bleeding complications if the anticoagulant is used.

Physicians examined the charts of 2295 21-40 year old oral contraceptive (OC) users who presented at 2 hospitals in France with venous disorders to determine the effect of various OCs on the functional symptomatology of venous disorders. The hospitals are the Hospital Notre Dame du Bon Secours in Paris and the Hospital Beaujon in Clichy. The various symptoms have existed between more than 1 year and greater than 3 years. The women used OCs with either a monophsic, biphasic, or triphasic minimal dose (304-40 mcg estrogen and 0.15-1 mg progestogen) or a monophasic normal dose (50 mcg estrogen and 500 mg progestogen). Over the course of OC use, the normal dose OC caused more significant intensity of heaviness, pain, and abnormal sensation (e.g., burning, prickling, or formication) than the minimal dose OCs. Other symptoms examined but not significantly affected by estrogen and progestogen dose are cramps and edema. These results and the fact that functional symptomatology appears several years before dilatation with or without reflux of the saphenous veins and other varices indicate that estrogens, progestogens, or their associative action facilitate varicose vein development in individuals with factors which predispose them to vascular disorders (familial history, prolonged standing, obesity, and sedentary). They also aggravate the superficial venous state in these patients.
