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.

Relationship between anterior fontanelle pressure measurements and clinical signs in infantile hydrocephalus

The treatment of choice in progressive hydrocephalus is drainage of cerebrospinal fluid in order to reduce elevated intracranial pressure (ICP). Defining the right moment for surgical intervention, however, in a hydrocephalic infant on the basis of clinical signs alone can be a difficult task. Clinical signs of raised ICP are known to be unreliable and sometimes even misleading. In the present study, the relationship between long-term anterior fontanelle pressure (AFP) measurements and clinical signs was investigated in 37 infants with hydrocephalus. The decision as to whether to operate or not was based on clinical signs alone; AFP values were not taken into account. There was an overall difference between the non-operated group and the preoperative measurements in the operated group, and also between the preoperative and the postoperative measurements in the latter, in regard to both AFP measurements and clinical signs. Almost all preoperative AFP values were increased. The direct correlation () between most individual clinical signs and AFP levels, however, was low (=0.15–0.41). The clinical sign tense fontanelle showed the best correlation with the AFP levels (=0.75). Furthermore, using logistic regression analysis, no combination of clinical signs could be found which reliably predicted the AFP. The relationship between the AFP pressure variables and clinical signs was also examined. The pathological A-waves occurred only in the presence of raised (baseline) AFP, a situation in which considerably more frequent B-waves were observed as well. It was concluded that clinical signs of raised ICP in infantile hydrocephalus are not very reliable and AFP monitoring can therefore provide valuable information on intracranial dynamics in patients with dubious neurological manifestations of progressive hydrocephalus.     

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.     

Prevention of anterior cruciate ligament injuries in soccer

Proprioceptive training has been shown to reduce the incidence of ankle sprains in different sports. It can also improve rehabilitation after anterior cruciate ligament (ACL) injuries whether treated operatively or nonoperatively. Since ACL injuries lead to long absence from sports and are one of the main causes of permanent sports disability, it is essential to try to prevent them. In a prospective controlled study of 600 soccer players in 40 semiprofessional or amateur teams, we studied the possible preventive effect of a gradually increasing proprioceptive training on four different types of wobble-boards during three soccer seasons. Three hundred players were instructed to train 20 min per day with 5 different phases of increasing difficulty. The first phase consisted of balance training without any balance board; phase 2 of training on a rectangular balance board; phase 3 of training on a round board; phase 4 of training on a combined round and rectangular board; phase 5 of training on a so-called BABS board. A control group of 300 players from other, comparable teams trained normally and received no special balance training. Both groups were observed for three whole soccer seasons, and possible ACL lesions were diagnosed by clinical examination, KT-1000 measurements, magnetic resonance imaging or computed tomography, and arthroscopy. We found an incidence of 1.15 ACL injuries per team per year in the control group and 0.15 injuries per team per year in the proprioceptively trained group (P<0.001). Proprioceptive training can thus significantly reduce the incidence of ACL injuries in soccer players.     

Comparison of augmented and non-augmented anterior cruciate ligament reconstruction combined with high tibial osteotomy

In a follow-up study 27 patients were evaluated after anterior cruciate ligament (ACL-)reconstruction combined with high tibial osteotomy because of chronic rupture of the ACL, cartilaginous lesions of the medial compartment and varus malalignment. They were divided into two groups. In 14 patients (non-LAD group) ACL reconstruction was performed using the central third of the autologous patellar tendon modified according to Eriksson-Trillat. Thirteen patients (LAD group) underwent repair with the same technique, but a Kennedy ligament augmentation device (LAD) in hot dog technique and fixed over the top was added. The postoperative treatment was the same in both groups. All patients were examined according to IKDC criteria. KT-1000 arthrometer testing at maximum manual traction was performed. Although the mean follow-up interval was more than double in the non-LAD group (non-LAD: 127 months vs LAD: 58 months), the subjective and clinical results, IKDC evaluation and KT-1000 arthrometer testing results were similar, showing no statistically significant difference. Further, no complications due to the use of LAD occurred. In this study no evident functional or clinical advantage from the augmentation performed could be shown.Investigation performed at the Department of Orthopaedic and Trauma Surgery, University Hospital Basle, Switzerland.

Cystoid macular edema in anterior chamber lens implantation following posterior capsule rupture

By comparing the incidence of cystoid macular edema (CME) in three groups of patients having different surgical procedures, we attempted to assess the role of vitreous loss as a risk factor for CME development. In the first group (n = 470), the surgical procedure was extracapsular cataract extraction followed by implantation of posterior chamber lens (EC-CE + PC-IOL). The second group (n = 42) had extracapsular cataract extraction which was complicated by posterior capsule rupture, and therefore anterior vitrectomy followed by implantation of anterior chamber lens had to be performed (ECCE + anterior vitrectomy + AC-IOL). In the third group (n = 22) the surgery was intracapsular cataract extraction followed by anterior chamber lens implantation (ICCE + AC-IOL). The third group was included in this follow up study to assess the role of AC-IOL as a possible causative factor for development of CME in uncomplicated cases of ICCE and AC-IOL. The difference of incidences of CME in the second and third group would therefore depend mostly on the vitreous loss. The incidence of CME diagnosed by fluorescein angiography in the first, second and third group was 1.5% (7/470), 35.7% (15/42) and 9.0% (2/22), respectively. All patients who developed CME were treated with combination of corticosteroid-antibiotic drops, dexamethasone retrobulbarly (40 mg/day) and peroral indomethacine (25 mg/day/6 weeks). This therapeutic regime resulted in only moderate improvement of visual acuity.Abbreviations AC-IOL anterior chamber intraocular lens - CME cystoid macular edema - ECCE extracapsular cataract extraction - ICCE intracapsular cataract extraction - IOL intraocular lens - PC-IOL posterior chamber intraocular lens     

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.
