Based on more than 10 million diabetic patients in the United States and an estimated prevalence of 15% for chronic cutaneous ulcers, there are approximately 1.5 million patients with this problem. These nonhealing cutaneous ulcers result in a high rate of lower extremity amputations in the diabetic population. Patients with diabetes have many complications that cause chronic cutaneous ulcers. These include peripheral vascular disease, autonomic and sensory neuropathy, impaired host defense against infection, and delayed wound repair. To treat diabetic patients with chronic cutaneous ulcers effectively all the complicating factors must be addressed. In this review we discuss the surgical care of these patients and the use of growth factors in combination with a comprehensive treatment algorithm.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The first six articles deal with various aspects of system function, from triage to analysis of outcome. The next series of articles reviews work in progress evaluating optimal fluid for resuscitation. Hypertonic saline and dextran combinations have been shown to restore vital signs better than isotonic solutions; they are safe, require smaller volumes, and may improve head injury outcome. Danger lies in the restoration of perfusion without hemorrhage control. Two articles on emergency thoracotomy review the indications and outcome in blunt and penetrating trauma. Survival in blunt trauma is virtually zero. An article and two editorials summarize state of the art for diagnosis and treatment of proximity vascular injury. Two articles describe the potential use of the new technique of transesophageal echocardiography. This new modality has not formed a solid indication at present and can be considered investigational in trauma care.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589818","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The case for minimal margins and delayed regional node dissection for high-risk cutaneous melanoma.","authors":"N Cascinelli,&nbsp;F Belli","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Some aspects of the surgical treatment of cutaneous melanoma are still currently debated. There is presently a general agreement in favor of a less wide excision of primary lesions. Specifically, data coming from a randomized study of the World Health Organization (WHO) Melanoma Programme indicates that the width of resection has no impact on either disease-free and overall survival of 612 stage I entered patients. Opportunity of an elective (ELND) or delayed (DLND) lymph node dissection remains much more controversial. Complications, including lymphedema, associated with this type of surgery, and no evidence of regional lymph node disease in at least 70% of clinical stage I patients submitted to node dissection, argue for avoiding ELND. Some studies show a positive value for ELND, but they are flawed by biased entry of patients into the ELND group, and conclusions are not derived from randomized studies. Two prospective trials show that ELND does not improve the prognosis of patients with stage I cutaneous melanoma. The results of the WHO study of 553 cases will be evaluable at 20 years. So far, on the basis of many biologic, clinical, and statistical findings, there is no evidence, in our opinion, of a substantial benefit related to ELND.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surgical treatment of peptic ulceration. 消化性溃疡的外科治疗。

{"title":"Surgical treatment of peptic ulceration.","authors":"B E Stabile","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Evidence continues to accrue that proximal gastric vagotomy is a safe and effective elective operation for duodenal ulcer. Recurrent ulceration remains the major shortcoming of the procedure but reoperation is rarely required. Laparoscopic surgery for peptic ulcer disease is rapidly evolving with anterior seromyotomy and posterior truncal vagotomy emerging as the elective procedure of choice. Perforated ulcer can also be treated by laparoscopic techniques in some cases. Hemorrhage is often amenable to initial endoscopic control measures, but when surgery is required, a definitive acid-reducing operation should be employed. Ulcerogenic drug use appears to be responsible for an increasing number of emergency interventions for life-threatening peptic ulcer complications, although simple closure of perforation due to such drugs may be sufficient surgical treatment. Long-term follow-up data suggest that there is a real risk increase for gastric remnant cancer development 20 years after partial gastrectomy for peptic ulcer but the value of regular endoscopic screening of patients at risk has not been demonstrated. The long-acting somatostatin analogue, octreotide acetate, has been shown to ameliorate the symptoms of the postoperative dumping syndrome markedly, although the mechanism of action remains largely unknown.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18589481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
