Prognostic factors for patients with advanced stage serous borderline tumours of the ovary.

BACKGROUND: The aim of this study was to determine the prognostic factors for patients with advanced stage, low malignant potential ovarian tumour (LMPOT). PATIENTS AND METHODS: A retrospective review of 80 patients with serous LMPOT and peritoneal implants treated at or referred to our institution was carried out. RESULTS: Sixty-five patients had non-invasive implants. Fifteen patients had invasive implants. Twenty-nine patients had stage II and 51 patients had stage III disease. Three patients died of evolutive invasive disease and four of complications of treatment. The only prognostic factor of progression to 'evolutive invasive disease' is the pathologic subtype of peritoneal implants. The 5-year rates of evolutive invasive disease in patients with non-invasive implants and invasive implants were 2% and 31%, respectively (P <0.002). CONCLUSIONS: In this series, the only prognostic factor for patients with advanced stage borderline tumour is the type of peritoneal implant. More patients died of the treatment's complications than of the disease itself. The patients' prognosis with non-invasive implants seems to be excellent, and conservative management could be discussed in younger patients.     

四种小儿动脉导管未闭堵闭术的临床应用:附127例报告

本文采用四种不同的介入治疗方法堵闭动脉导管共127例,成功率海绵塞法为92％(23/25例),双面伞器法为98.6％(66/67例),钮扣式补片法为100％(26/26例),弹簧圈器法为100％(9/9例)。海绵塞法和弹簧圈器无残余分流;术后6个月双面伞器法残余分流为7％(5/67例),钮扣式补片法为15％(4/26例)。钮扣式补片法和弹簧圈器法无并发症,海绵塞法为24％(6/25例),双面伞器法为4％(3/67例)。我们认为,钮扣式补片法及弹簧圈器法在小儿动脉导管未闭的介入治疗中具有较大的应用价值。     

Effects of super-extended paraaortic lymphadenectomy (PAL) on biological responses in totally gastrectomized patients with T3 or T4 gastric cancer

Background. In Japan, much attention has recently been paid to super-extended paraaortic lymphadenectomy (PAL) for the treatment of advanced gastric cancer. However, it has been reported that PAL is associated with increased morbidity and mortality, as compared to conventional extended lymphadenectomy (D2 or D3). Therefore, an analysis of the effects of PAL on perioperative changes in the biological responses of patients essential for determining the potential utility of this procedure. Methods. The current non-randomized prospective study included evaluations of perioperative changes in parameters of surgical stress (series I; serum levels of antidiuretic hormone, interleukin-6, trypsin, and phospholipase A ₂ ) and immunocompetence (series II; phytohemagglutinin- and concanavalin A-induced blastogenesis, activity of natural killer cells and the ratio of CD4 cells to CD8 cells) in patients with advanced gastric cancer (T3 or T4), comparing groups treated with D3 plus PAL ( n = 12) and D3 ( n = 13), and a control group with early gastric cancer ( n = 16) treated with D1 lymphadenectomy (perigastric N1 nodes) between April 1995 and April 1997. Results. The duration of surgery and the amount of blood lost were longer and greater in the D3 plus PAL group than in the D3 and D1 groups. D3 plus PAL and D3 were associated with significant postoperative increases in parameters of surgical stress, as well as with significant postoperative immunosuppression, compared to results with D1. However, there were no significant differences in the respective parameters between the D3 plus PAL and D3 groups. Conclusions. Our results indicate that there are no essential differences in patients' biological responses between D3 plus PAL and D3 lymphadenectomy. It appears that PAL-associated morbidity can be minimized by very careful manipulation during the dissection of paraaortic lymph nodes.

影响吻合器痔上黏膜环切术疗效的因素及改进方法

目的探讨影响吻合器痔上黏膜环切术(PPH)疗效的因素及改进方法。方法使用美国强生一次性PPH吻合器或国产PPH吻合器对68例痔病患者进行PPH手术，在手术改进前后分别对每例黏膜环切的标本以及症状的改善进行测量及观察。结果方法改进前，标本宽度为0．5～2．6cm，术后痔核回缩率75％；方法改进后，标本宽度为3．0～3．5cm，术后痔核回缩率100％。结论影响PPH手术疗效的因素主要是肛垫的提升复位与肛垫的固定。通过改进方法克服不利因素，使环切黏膜的宽度达到要求，进而使肛垫提升复位并得以固定，痔核回缩效果满意。     

Tentorial Meningiomas. Report on Twenty-Seven Cases

Summary ? Objective. Report our experience with 27 tentorial meningiomas (TM) surgically treated between 1985 and 1998.  Methods. The records of 27 patients with TMs were retrospectively reviewed for clinical presentation, neuroradiological evaluation, surgical treatment and long-term outcome. The extent of tumor resection was scored according to the Simpson's grading for tumor removal. Long-term results were evaluated according to the Glasgow Outcome Score (GOS).  Results. The average age was 53 years. Female predominance was 74%. The most common complaints at presentation were headaches (51%), gait ataxia (33%), memory disturbances (30%) and hypo-acousia (30%). A classification of TMs into 5 subgroups according to tumor site is proposed on the basis of imaging studies. A cerebrospinal fluid shunt was established prior to direct approach in 7 patients and as the sole procedure in one inoperable patient. Twenty-seven direct approaches were undertaken in 26 patients, including 17 infratentorial and 10 supratentorial approaches. Total tumor removal was achieved in 20 patients (77%) and subtotal removal in 6 (23%). Fifteen patients (55%) experienced 22 postoperative complications. One patient died three months after a subtotal resection (mortality=3,7%). With a mean follow-up of 54 months, all 26 survivors are currently alive with 23 having resumed their normal activities and 3 needing assistance. Five of 6 patients with subtotal resection survived and were followed for a period ranging from 72 to 132 months: none showed residual tumor progression and no re-operation was considered. An additional patient experienced a ?true? recurrence 6 years after total removal, with no tumor progression 2 years after his recurrence was recognized.  Discussion. The best surgical approach to TMs is still a controversial matter. The advantages and drawbacks of conventional versus transbasal approaches are reviewed. Our experience suggests that subtotal removal can be associated with long recurrence-free intervals and preserved quality of life. TMs located at the tentorial edge carried a definitely worse prognosis than peripheral forms.     

CT-Based Needle Marking of Superficial Intracranial Lesions for Minimal Invasive Neurosurgery

A CT-based method of marking superficial intracranial lesions with a needle is presented. This form of neuronavigation can be applied in every neurosurgical centre. Owing to its rapid application it is also suitable for cases of emergency. The neurosurgical approach can be centred precisely over the lesion providing for a minimally invasive operation. The method has proved its efficacy in numerous cases of haematomas and cystic lesions.

A foreign body (gossypiboma) in pregnancy: first report of a case

The technical name for a surgical sponge left in the body of a patient is inadvertent “gossypiboma.” The word is derived from the Latin word Gossypium for cotton and from the Kiswahili word boma for “place of concealment.” These retained sponges were first seen as “textilomas,” but were renamed “gossypiboma” in 1978. The first case was reported by Wilson in 1884. These are rarely are retrieved in the literature, because of legal complications. A higher incidence of retained laparotomy sponges has been reported in association with gynecological procedures. We report a case of gossypiboma in the 38th week of pregnancy that imitated an ovary neoplasm.
