OVERVIEW FOR THE DIAGNOSIS AND TREATMENT OF GALLBLADDER CARCINOMA

Objective. To improve the recognition of diagnosis and treatment of gallbladder cancer. Methods. Retrospective analysis of 52 cases of gallbladder carcinoma in our hospital from 1988 to 1998. Results. Preoperative diagnostic rate was 90.3%, of which 12 cases (23%) were early stage of carcinoma. The total operation resection rate was 55.8%, for which only 17.8% were advance stage of carcinoma. Conclution. The early diagnosis is the key factor of increasing treatment successful rate. The following are the symptoms that raise our special attention to carcinoma of gallbladder: ( 1 ) Age over 50 have recurrent eholecysfitis and with past history of gallstone; (2) Congenital malformation of bile duct; (3) Local thickening and irregularity of gallbladder,gall; (4) Polypoid lesion larger than lem inside gallbladder; (5) Atrophic gallbladder; (6) Intraluminal stone of gallbladder does not move when change in body position; (7) Regional lymph node enlargement.     

Multiviszerale Resektion des fortgeschrittenen kolorektalen Karzinoms Multivisceral resection in advanced colorectal carcinoma

Zusammenfassung Berichtet wird über die operative Behandlung von 1232 Patienten mit einem kolorektalen Karzinom aus dem Zeitraum 1.09.1984 bis 1.01.1990. Entsprechend einer Resektionsquote von 90,3 % wurden 1112 Patienten (kurativ: n = 917, palliativ: n = 195) reseziert. Bei 82 Patienten war wegen Organüberschreitung des Tumors eine multiviszerale Resektion von einem oder mehreren benachbarten Organen (69mal kurativ, 13mal palliativ) notwendig. Komplikationsraten (26,7% zu 27,5 %) und die 30-Tageletalität (3,4% zu 2,9 %) waren in beiden Gruppen der kurativ and kurativ erweitert resezierten Patienten gleich. Die Berechnung der Fünfjahresüberlebensrate ergab für die kurativ resezierten Patienten ohne Erweiterung einen Wert von 58% gegenüber 55 mit Erweiterung. Auch die Subgruppenanalyse ergab keinen Unterschied in den einzelnen Stadien. Die Ergebnisse lassen den Schlul zu, da bei gleicher Komplikations-und Letalitätsrate die kurativ erweiterte Resektion von pT3- and pT4-Tumoren gleiche Spdtergebnisse wie die entsprechende Behandlung von nicht erweitert resezierten pT3-Tumoren erwarten lät. Die Daten zeigen, da eine Infiltration von Nachbarorganen durch ein kolorektales Karzinom nicht als Inoperabilitätskriterium gelten darf.

From 1 September to 1 January 1990, a total of 1232 patients underwent surgery for colorectal cancer. Resection was performed on 1112 (90.3%) patients. It was curative in 917 cases and palliative in 195. Multivisceral resection was necessary 82 times because of tumour infiltration of adjacent organs (curative: 69 cases; palliative: 13 cases). The complication rate (26.7% vs 27.5%) and mortality rate (3.4% vs 2.9%) were similar to those for curative resections without multivisceral extension. The 5-year survival rate was also similar in the two groups (58% vs 55%). These results show that curative multivisceral resections can lead to the same long-term results as conventional curative resections. These data are encouraging, and tumour infiltration of neighbouring organs should not be taken to demonstrate inoperability.

     

Volumetric reconstruction and stereotactic computer assisted resection in intracerebral lesions

Summary Since 1990 112 patients have undergone Stereotactic resection of intra-axial tumoural lesions with volumetric reconstruction, using the Kelly-Goerss system. Stereotactic integration of CT, angiographic and particularly MRI information, together with three-dimensional information of the lesion, provide an innovative evaluation of the most appropriate surgical approach, even for each single patient. The main limitation of this surgical method is in cases where the infiltrating part of the tumour is pre-eminent, while it can allow macroscopically complete resection of well circumscribed lesions, almost independently of their location and volume. Some technical aspects of Stereotactic resection of brain tumours are discussed in the light of our experience.     

Acquired hyperoxaluria and haematuria in children

Two children with extensive ileal resection are reported. They developed gross haematuria of non-glomerular origin, without stones or nephrocalcinosis. Previous reports indicate that acquired hyperoxaluria is common in children with a variety of intestinal disorders. Our patients had hyperoxaluria. We think that hyperoxaluria may be the cause of haematuria through a pathogenetic mechanism similar to the one ascribed to haematuria secondary to hypercalciuria and hyperuricosuria.     

The transurethral resection syndrome

The transurethral resection syndrome ("TUR syndrome") is caused by absorption of electrolyte-free irrigating fluid, and consists of symptoms from the circulatory and nervous systems. The clinical picture is inconsistent and the syndrome is easily confused with other acute disorders. Mild forms are common and often go undiagnosed, while severe forms of the TUR syndrome are rare and potentially life-threatening. The pathophysiology is complex but includes four mechanisms: circulatory distress from the rapid absorption of electrolyte-free irrigating fluid, adverse effects of glycine, dilution of the protein and electrolyte concentrations of the body fluids, and disturbance of renal function. The treatment of the TUR syndrome consists of general life support and in specific treatment directed towards hypotension, hyponatraemia and anuria. Methods to lower the uptake of irrigating fluid are widely used and probably reduce the incidence of the TUR syndrome. However, patient safety can be guaranteed only if the absorption is monitored. An irrigating fluid containing tracer amounts of ethanol can be used for this purpose. This permits the uptake of fluid to be indicated by measuring the concentration of ethanol in the patient's exhaled breath.     

Unusual fractures and dislocations of the axis vertebra

Seven percent of 400 patients with cervical spine fractures and/or dislocations had unusual lesions of the axis. The authors have analyzed axis injuries by review of radiographs and clinical data and have derived a classification of traumatic conditions. Uncommon traumatic axis abnormalities are discussed with reference to incidence, causes, clinical findings, mechanism of injury, and roentgen characteristics.Picker Scholar, James Picker Foundation

Clinical significance of interstitial collagen deposition at the invading edge in oral cancer: Immunohistochemistry for type I collagen

Background Changes in interstitial collagen in human oral cancer have not yet been fully studied. We examined the relationship between the degree of interstitial collagen deposition at the invading edge of the tumor, and the clinical and pathologic findings in oral squamous cell carcinoma. We also investigated the therapeutic implication of the changes in distribution patterns of collagen deposition by comparing biopsy specimens and surgical specimens. Methods Immunohistochemical staining was performed by the streptavidin-biotin method using antibody against human type I collagen for visualizing interstitial collagen in 50 biopsy and 45 surgical specimens. Results Carcinomas with scanty interstitial collagen in biopsy specimens tended to have highly malignant characteristics. Large carcinomas with scanty deposition both in biopsy and surgical specimens were likely to have positive resection margins in spite of radical surgery. Conclusion Immunostaining patterns for type I collagen of oral squamous cell carcinomas can provide information of importance in determining safe resection margins.     

环枢关节紊乱症的临床研究

环枢关节紊乱症，从发病机理到临床表现，乃是颈椎病中较复杂的疑难顽症。用常规诊治方法，疗效不佳。本研究提出新的诊断依据与治疗方法，对３２０例病者随机分为治疗组１６６例（采用改进的诊治方法），对照组１５４例（用常规诊治方法）对照进行疗效观察。结果显示：治疗组治愈率与总有效率及康复率均高于对照组。有非常显著差异，Ｐ＜０．０１。而疗程较对照组短。环枢关节紊乱症的临床研究有利于颈椎病诊治水平的提高，运用于临床，疗效好，效益高，具有推广应用价值。
