Postoperative complications in laser in situ keratomileusis.

Laser in situ keratomileusis (LASIK) has become the most common procedure to correct refractive errors in North America. Increasing numbers of patients and surgeons are choosing LASIK in the management of low and moderate myopia, astigmatism, and hyperopia. LASIK presents a unique group of postoperative challenges and complications. It is important to be able to identify these complications in the early and late postoperative periods and to provide effective management. In this article, we review the most commonly encountered early and late postoperative complications after LASIK and the most current methods in prevention and treatment.

Leukocyte infiltration and secretion of cytokines in pleural drainage fluid after thoracic surgery: impaired cytokine response in malignancy and postoperative complications.

STUDY OBJECTIVE: To assess the postoperative course of pleural leukocyte counts and cytokine concentrations in patients with malignant and nonmalignant lung disease who underwent thoracic surgery. PATIENTS AND INTERVENTIONS: A total of 21 patients undergoing thoracic surgery were included in the study. Twelve patients had a malignant disease, and 9 had a nonmalignant disease. Six patients underwent video-assisted thoracoscopy and 15 underwent thoracotomy. Pleural drainage fluid from the chest tubes was collected postoperatively at Oh, 3h, 6h, 12h, 24h, 48h, 72h, and 96 h. The same schedule, as well as one additional preoperative sample, was applied for blood collections. RESULTS: A trend toward lower concentrations of tumor necrosis factor-alpha (TNF-alpha), granulocytemacrophage colony-stimulating factor, and interleukin-10 was observed in patients with malignant disease compared to those without malignancy. These differences achieved significance for TNF-alpha in the drainage fluid of those patients with nonmalignant disease who had undergone formal thoracotomy. Patients with malignant disease showed significantly lower macrophage fractions in drainage fluid and lymphocyte fractions in serum. All patients with complications had malignant disease and showed the lowest cytokine concentrations, as well as the lowest fractions of both macrophages in drainage fluid and lymphocytes in serum. CONCLUSION: The data suggest that malignancy may lead to impairment of the wound-healing process via modification of the inflammatory cell infiltrate and locally released cytokines.

[Benefit of assessment of cytokines in inflammatory postoperative complications (review)].

Systemic inflammatory response syndrome and the resulting complications continue to be important causes of morbidity in surgical patients. A favourable prognosis of patients with postoperative inflammatory intraabdominal complications is limited by forwardness if diagnosis of this severe complication. Cytokines play a significant role not only in regulating pathogenic mechanisms, during the rising of SIRS, but can themselves directly lead to tissue damage. Increased concentrations of inflammatory cytokines observed in the initial phase of postoperative complications have great significance in the early diagnosis of systemic complications. Procalcitonin, alongside to cytokines, appears as a significant parameter. Despite lots of its pathophysiological points are unclear it is a highly selective and specific indicator of systemic bacterial inflammation. Leptin is not only a hormone of adipocytes but also a member of inflammatory network of cytokines and acute phase reactants. Leptin is possibly a necessary factor for adequate course of acute phase reaction. Proinflammatory cytokines as interleukin-1 or tumour necrosis factor-alpha are the main regulatory factors of leptin in this period.

[Efferent methods in the therapy of puerperal and postoperative complications].

Ninety-six patients with chorioamnionitis in labor were treated. Clinical observations and laboratory findings demonstrated high efficiency of multiple-modality treatment including use of efferent methods: plasmapheresis, incubation of cell mass with antibiotics, and ultra-violet exposure of the blood.

Pneumatic retinopexy. An analysis of intraoperative and postoperative complications. The Retinal Detachment Study Group.

There have been 26 series (1,274 eyes) published on the use of pneumatic retinopexy for selected retinal detachments. Eighty percent were reattached with a single procedure and 98% with reoperations. New retinal breaks occurred in 13% and proliferative vitreoretinopathy in 4%. The three complications reported with pneumatic retinopexy but not with scleral buckling are subretinal gas, gas entrapment at the pars plana, and subconjunctival gas. Twenty-six complications of pneumatic retinopexy, most of which may also occur with scleral buckling, are discussed as to incidence, cause, prevention, and management.
