2340例胰腺癌临床病例分析

目的 探讨提高胰腺癌治愈性切除相关因素和获得更佳疗效。方法 中国抗癌协会胰腺癌专业委员会回顾性分析了8省2市14大医院的1990年-2000年诊治的2340例胰腺病例。多因素生存分析采用Cox比例风险模型找出可能影响胰腺癌病人预后的独立因素。单因素生存分析用寿命表法计算,以生存曲线描述生存率,并进行Gehan比分检验。结果 COX单因素分析表明在a=0.05水平上有意义的有年龄、职业、病程、肿瘤部位、手术方式、术后胰瘘、术后肝衰、化疗、TNM分期、免疫治疗、有无肝转移、肠系膜上血管有无侵犯等变量。COX多因素分析表明在a=0.05水平上有意义的有患者年龄、手术方式、术后胰瘘、术后肝衰、化疗、免疫治疗等变量,这些变量为影响胰腺癌预后的独立因素。根治性手术者相对于未手术者,以及化疗、免疫治疗均为保护性因素。其中40岁以上的占了92.91％,40岁以下的仅占7.09％。胰头癌根治性手术组中位生存时间为 17.11个月,1年、3年和5年生存率分别为54.36％、13.47％、8.47％。结论 有必要将40岁以上的人群视为高危人群,能及时发现早期病例。各种综合治疗措施的结合都将有助于改善胰腺癌患者的生活质量和延长生存期。

Do the complications of mastoid surgery differ from those of the disease?

During mastoid surgery there is a risk to the facial nerve and hearing but at present it is unclear how substantial this risk is. This information is necessary for adequate informed consent to be given, as consent requires information about both the potential risks of the surgery as well as the risks of leaving the disease untreated. The aim of this study is to establish the risks of mastoid surgery and the incidence of complications as a consequence of mastoid disease. The records of all patients undergoing mastoidectomy between 1985 and 1994 were reviewed for preoperative and intra-operative complications. Preoperatively there were 21 (2%) facial nerve palsies, 67 (6.5%) dead ears and 58 (5.7%) intracranial complications of the mastoid disease. If this risk is extrapolated for the population of the Western Cape over a 40-year period (average expected life-span after presentation), the risk of developing a serious complication (facial palsy, dead ear or intracranial) from mastoid disease during this period was 3.8%. The incidence of intra-operative iatrogenic facial nerve palsy was 1.7% (n = 17) and of dead ear was 1.7% (n = 17). Although the comparative risk of developing a severe complication from untreated disease was similar to the risks of surgery (facial palsy, dead ear), the number (58) of intracranial life-threatening preoperative complications presenting in the 10-year period reviewed was significant. These figures provide a base from which otologists can inform patients about the possible risk of mastoid surgery as well as allowing these risks to be compared with the risks of leaving the disease untreated.     

Tubeless Laryngotracheal Surgery in Infants and Children via Jet Ventilation Laryngoscope

We present the first use of tubeless superimposed combined high- and low-frequency jet ventilation (SHFJV) with a jet laryngoscope in laryngotracheal surgery in infants and children. Twenty-eight patients underwent 53 operative procedures. The average age of the patients was 7.3 years. The most common diagnoses were laryngeal papillomatosis and subglottic stenosis. The duration of jet ventilation averaged 33 min. The gas exchange was sufficient in each case. The advantages of SHFJV in the surgery of the laryngotracheal area in infants and children are optimal view at the larynx and trachea, maximum space for the handling, application of the laser without risks, no time limitation, suitability for stenosis, and neither anesthetic nor surgical complications.     

The triangular vaginal patch sling for stress urinary incontinence and hypermobile urethra

OBJECTIVE: We describe an alternative sling procedure that permits concomitant correction of urethral hypermobility and urinary incontinence through a single surgical exposure. STUDY DESIGN: Fifteen women with severe urinary stress incontinence and urethral hypermobility underwent a sling procedure by creation of a simple triangular patch from the anterior vaginal wall. RESULTS: The mean operative time for the vaginal sling procedure was 38 minutes (range 29 to 65 minutes) in addition to other operations. The mean postoperative hospital stay was 7.7 days (range 5 to 13 days) and all patients were routinely discharged with an indwelling Foley catheter. Spontaneous micturition occurred in 12 patients after a mean period of 25 days (range 13 to 36 days). In three cases long-term catheterization was necessary. By subjective and objective evaluations, all the patients were cured of their stress incontinence. CONCLUSION: The triangular vaginal patch with the single sutures on each side provides an alternative approach for bladder neck stabilization that may permit a more anatomic suspension of a hypermobile urethra.(Am J Obstet Gynecol 1997;177:31)     

The value of intraoperative cystoscopy in urogynecologic and reconstructive pelvic surgery

OBJECTIVE: Our goal was to evaluate the role of intraoperative cystoscopy during surgery for pelvic organ prolapse and urinary incontinence. STUDY DESIGN: Charts of 224 consecutive patients who had intraoperative cystoscopy performed after urogynecologic surgery were reviewed. RESULTS: Nine injuries occurred that were unsuspected before cystoscopy, for an incidence of 4%. Six ureteral ligations occurred, four after Burch cystourethropexy and two after vaginal culdoplasty. Intravesical sutures were noted after two Burch procedures, and another injury occurred with passage of fascia lata through the bladder during a pubovaginal sling procedure. Eight injuries were managed by removal and replacement of the suture or sling with only one requiring ureteroneocystotomy. When patients with injuries were compared with those without, there were no statistical differences in demographic or surgical parameters. CONCLUSIONS: The potential for damage to the lower urinary tract is significant with complex urogynecologic surgery. Because of the increased and delayed morbidity associated with unrecognized injury, intraoperative surveillance cystoscopy should be considered a part of all such procedures.(Am J Obstet Gynecol 1997;177:71)     

Splenectomy during primary and secondary cytoreductive surgery for epithelial ovarian carcinoma

Scarabelli C, Gallo A, Campagnutta E, Carbone A. Splenectomy during primary and secondary cytoreductive surgery for epithelial ovarian carcinoma. Int J Gynecol Cancer 1998; 8 : 215–221.
Splenectomy is occasionally indicated to achieve optimal cytoreduction during surgery for epithelial ovarian cancer. Between January 1989 and December 1996, 40 epithelial ovarian cancer patients underwent splenectomy: 14 patients during primary surgery and 26 during secondary cytoreductive surgery. Splenectomy was performed for tumor reduction in 34 patients (85 %) and for iatrogenic injury in six patients (15%). The spleen was removed because of parenchymal splenic metastases in nine patients (22.5 %), significant hilar and/or capsular disease in 10 patients (25 %), and perisplenic disease in 15 patients (37.5%). The histopathological diagnosis of the resected spleens showed microscopic hilar disease in four patients who had the spleen removed because of iatrogenic injury and no disease in only two patients. Splenectomy could be carried out with an acceptable morbidity. Left-sided pleural effusion was the most frequent complication. The estimated two-year survival rate for patients who underwent splenectomy during primary surgery with no residual disease and <2 cm intraperitoneal residual disease was 83% and 42%, respectively. Nine of these patients (64.3%) had recurrent disease. The median time to recurrence was 11 months (range 5–18). The estimated two-year survival rate for patients who underwent splenectomy during secondary surgery with no residual disease and <2 cm intraperitoneal residual disease was 78% and 24%, respectively. The estimated three-year survival rate was 0% for all these patients. The results of the present study show that splenectomy, if necessary to achieve optimal debulking, should be considered in previously untreated patients with no intraperitoneal residual disease and in patients with late (>1 year) recurrent disease.     

Facial nerve outcome in lateral skull base surgery for benign lesions

Objective: To statistically identify factors most important in affecting CN7 outcome in lateral skull base surgery for benign lesions. Study Design: A retrospective review of 217 nonmalignancy lateral skull base procedures from 1970 to 1995 at the Otology Group in Nashville. Methods: Charts were reviewed for epidemiology, histopathology, staging, type of CN7 mobilization (none, short, long, severance with reanastomosis, and resection), preoperative and postoperative CN7 function, surgery performed, and survival. Results: Average House-Brackman (HB) scores for mobilizations were as follows: short, 1.65: long, 2.74: and grafting, 4.33. Factors found to affect outcome in a statistically significant fashion were preoperative HB score, staging, type of CN7 manipulation, and surgical approach. Meningiomas were found to have a worse outcome than glomus tumors. Conclusions: Complete resection of tumors should be performed with minimal manipulation of the facial nerve based on regional anatomy and tumor anatomy. Laryngoscope, 108:1480–1484, 1998
