Is open surgery the solution to avoid morcellation of uterine sarcomas? A systematic literature review on the effect of tumor morcellation and surgical techniques.

PURPOSE: Today's surgical standard of care for uterine leiomyomas is laparoscopic and/or vaginal surgery with larger specimens requiring morcellation to avoid open surgery. This is often associated with intra-abdominal dissemination of cellular material which in case of a uterine sarcoma might result in iatrogenic seeding of malignant tumor cells. The aim of this systematic literature review is to evaluate the surgical techniques and the impact of accidental tumor morcellation on the outcome of patients postoperatively diagnosed with malignant uterine sarcomas. METHODS: The National Library of Medicine database (pubmed) and Web of science were searched individually using three different search terms ('morcel* sarcoma', 'survival, sarcoma, treatment, Uter*', and 'disease free survival, sarcoma, treatment, uter*'). After excluding duplicates and screening for relevance, 16 articles were left for full-text review, resulting in seven case series with more than 5 patients. RESULTS: The case numbers range from 14 to 123 patients with the majority of cases being leiomyosarcomas. CONCLUSION: There is no reliable diagnostic tool to differentiate a fibroid from a uterine sarcoma preoperatively. Tumor morcellation occurs in various open and closed surgical techniques and is not limited to laparoscopic surgery only. There is an urgent need for a presurgical diagnostic parameter.

Treatment cost evaluation of extrauterine gravidity: a literature review of medical and surgical treatment costs.

BACKGROUND: The diagnosis of extrauterine pregnancy is possible very early giving the patient and doctors treatment options. As the risks and success rate of medical and surgical treatment are similar, the decision is increasingly influenced by cost-effectiveness. OBJECTIVE: The following article systematically reviews the known literature regarding cost, decision criteria and possible follow-up. METHODS: Literature review of extrauterine gravity in combination with cost in the online National Library of Medicine since 1.1.1997 following the PRISMA recommendations. RESULTS: Six articles were identified in which the cost of the laparoscopic versus medical treatment is reviewed. In five articles, the medical treatment was shown to be more cost effective and in the sixth article the costs were found to be equal. The cost saving varies between 18 and 88% depending on the consideration of direct and indirect costs. If indirect expenses are considered, the total sum increases with treatment failures. Failure rates are given as up to 27% depending on the type of failure (surgical or medical). These rates seem to be linked indirectly with the ß-HCG levels. Predictive parameters for the successful medical treatment are missing. CONCLUSIONS: The treatment of small extrauterine gravidities in haemodynamically stable patients (defined by HCG levels <1,500 IU/l) is medically successful and cost-effective. With HCG levels between 1,500 IU/l and 3,000 IU/l, the treatment costs are similar. HCG levels >5,000 IU/l favour the surgical treatment as being more cost-effective. A similar cut-off for the sonographic imaging is missing.

Should a drain be placed in early breast cancer surgery?

BACKGROUND: The current surgical debate has led to a reduction in the extent of surgery performed and thereby to a reduced occurrence of surgical trauma and, over the recent years, reduced seroma formation. This reduction in surgical procedures calls the need for a drain into question. METHOD: Using Google Scholar and the National Library of Medicine (PubMed), a literature review was performed on systematic reviews and meta-analyses regarding breast cancer surgery ± axillary dissection. Additionally, randomized trials for the time period after the last systematic review were included and evaluated according to the Jadad score. RESULTS: The search returned 5 systematic reviews, in which a total of 1,075 patients were included (537 cases and 538 controls). Since the last review, no prospective randomized trial meeting the inclusion criteria has been published. The current reviews conclude that insertion of a drain is associated with a longer hospital stay and reduced seroma formation. The data regarding wound infection and drain insertion is inconclusive. The omission of a drain is associated with early discharge, reduced postsurgical pain, and early mobilization, but also with an increase in outpatient seroma aspirations. CONCLUSION: The omission of a drain is possible in early breast cancer surgery (wide local excision and sentinel node biopsy) with adequate surgical techniques and instruments.
