Acute appendicitis and ileal perforation with a toothpick treated by laparoscopy

A 69-year-old man underwent an emergency laparoscopic procedure after the acute appendicitis diagnosis has been established. Laparoscopic exploration showed inflamed appendix and perforation of terminal ileum with a swallowed part of the wooden toothpick. The treatment consisted of typical laparoscopic appendectomy and laparoscopic removal of the foreign body, followed by laparoscopic closure of the perforation site and lavage of the abdominal cavity. The postoperative course was uneventful and the patient was discharged from the hospital on day 3 after the operation.     

Indications for surgery in necrotizing pancreatitis.

The decision to operate on a patient with severe acute pancreatitis is often difficult and requires mature clinical judgment. Indications that are widely accepted include to establish the differential diagnosis, when the surgeon is concerned that the symptoms are due to a disease other than pancreatitis for which an operation is mandatory; in persistent and severe biliary pancreatitis, when an obstructing gallstone is lodged in the ampulla of Vater and cannot be managed endoscopically; in the presence of infected pancreatic necrosis; and to drain a pancreatic abscess, if percutaneous drainage does not produce the desired result. Other indications that are less well defined and somewhat controversial are the presence of sterile pancreatic necrosis involving 50% or more of the pancreas, when the pancreatitis persists despite maximal medical therapy, and when a patient''s condition deteriorates. For these last three indications, guidelines have been presented that permit a logical approach to management, although uncertainty remains. Surgeons should strive to describe in detail and precisely the clinical state of their patients at the time that an operation is done, as well as the findings and technical details of the operation. This should allow further refinement in the management of this vexing problem.     

Indications for angiography and surgery in carotid artery disease.

The results of angiographic investigation of 211 patients suffering from transient cerebral ischaemic attacks in the carotid territory have been reviewed. The greatest proportion of patients with carotid stenosis and who were referred for endarterectomy were those with a neck bruit ipsilateral to the affected hemisphere. Ocular involvement (amaurosis fugax) was associated with a still higher prevalence of angiographic abnormality, and carotid occlusion was commonest in this group. The implications for the management of patients with transient ischaemic attacks are discussed.     

Variation in rates of hospital admission for appendicitis in Wales.

In a study designed to investigate the variations in rates of admission to hospital for appendicitis in Wales Hospital Activity Analysis listings were analysed according to the sex and age of the patients and the month and day of the week of admission. The incidence of hospitalisation was greatest among boys aged 10-14 and girls aged 15-19. The number of admissions was higher on weekdays than at weekends, but there were no seasonal variations. Durations of stay differed between the 17 health districts. We conclude that admission rates vary mainly because of differing hospital admission policies. Admission is not wholly governed by the sudden onset of abdominal pain; other factors include the threshold of consultation of each patient, the referral habits of general practitioners, the availability of hospital beds, and the degree to which doctors and patients expect admission.     

Long-term anticoagulation. Indications and management.

Each year half a million persons in the United States receive long-term anticoagulant therapy to prevent venous and arterial thromboembolism. Unfortunately, the relative benefits and risks of anticoagulant therapy have not been adequately quantified for many thromboembolic disorders, and the decisions as to whether, for how long, and how intensely to administer anticoagulation are often complex and controversial. Several expert panels have published recommendations for anticoagulant therapy for different thromboembolic disorders; the primary area of disagreement among these panels concerns the optimal intensity of anticoagulation. Recent research and analytic reviews have helped to clarify both the risk factors for and the appropriate diagnostic evaluation of anticoagulant-induced hemorrhage. Clinicians must be aware of the nonhemorrhagic complications of anticoagulant therapy, particularly during pregnancy. The administration of anticoagulants is difficult both in relation to dosing and long-term monitoring. Knowledge of the pharmacology of the anticoagulants, an organized approach to ongoing monitoring, and thorough patient education may facilitate the safe and effective use of these drugs.
