Abstract
BACKGROUND In the examinations of the appraisal commission of Northern Rhine the third most frequent urologic errors are ascertained after surgical procedures. In order to prevent them, it is adequate to evaluate their causes. MATERIAL AND METHODS Urologic claims were examined that came before the appraisal commission for treatment errors of the Northern Rhine Physicians' Authority between 1975 and 2005. The results of the first 23 years were compared with those of the last 7 years. The judgment criteria were professional standards and required care. RESULTS Ninety-five treatment errors were registered in 1975-2005. From 1975 to 1998 there were 60 such errors (2.6 per year) and from 1999 to 2005 there were 35 (5.0 per year). These errors concerned diagnosis in 14.7% of cases (mainly testicular torsion), indication in 7.5%, and explanations of the surgery in 2.1%. About half the cases (46.3%) applied to surgical technique, especially for injuries to the spermatic cord, urinary bladder, ureter, or urethra. In nearly one third of cases (29.4%), errors were found in postoperative care, concerning especially lesions of the spermatic cord and ureter. CONCLUSIONS There is considerable risk of misjudging or even causing urologic disorders in abdominal and vascular surgery. This applies most strongly to diagnosis, above all for testicular torsion. Hernia surgery and colon resection are the treatments leading to the highest number of injuries to testicular vessels, ureter, bladder, and/or urethra. Such occurrences cannot be tolerated if they can be avoided or, if unavoidable, not recognized promptly and adequately managed.

Abstract
The expression of three sialylated mucin-associated antigens - sialosyl-Lewisa (SLEA), sialosyl-Lewisx (SLEX) and sialosyl-Tn (STN) - and their correlation with the TNM stage, histopathological growth pattern and prognosis was investigated in a series of 127 gastric carcinomas. Various classification systems (pTNM, WHO and Laurén) did not display any correlation with an expression of the sialomucin antigens under study. SLEA reactivity was strongly associated with an unfavorable outcome of the total population, whereas SLEX and STN did not exert such an impact. However, in the subgroups of pTNM stage I as well as pN0 patients, SLEA and SLEX reactivity of the tumors was associated with a worse prognosis. In the subgroup of diffuse-type cancers as defined according to Laurén's classification, the expression of all three antigens indicated a worsening of the prognosis.

Abstract
We investigated the effects of recombinant G-CSF (Filgrastim) on the function of neutrophils and the rate of infectious complications in an open-label, nonrandomized study of patients with esophageal cancer undergoing esophagectomy. In this single-center phase-II trial 20 sequential patients (19 evaluable) received Filgrastim at standard doses (300 microg or 480 microg) subcutaneously for 2 days prior to and up to 7 days after surgery. The phagocytotic activity of neutrophils and the oxidative burst in the study group and in an experimental control group (n=27) were measured on days -2, 2, and 10. Neutrophil function was enhanced in the Filgrastim-treated group by factor 1.2 for phagocytosis (p=0.016) and 1.4 for oxidative burst (p)=0.154). Leukocyte counts increased from 7.6 x 10(9)/l (day -2) to a maximum of 45 x 10(9)/l on day 6. No infection was reported in the study group (mean age 59.7 years; 13 men, seven women) up to 10 days after surgery. In contrast, 23 patients (29.9%) in a historical control group (mean age 56 years; 67 men, ten women) treated at the same center developed infections within the first 10 days (p = 0.008). In addition, no postoperative deaths occurred in the study group, compared with 9.1% in the group of historical controls. Thus, in this study, administration of Filgrastim stimulated neutrophil function in patients undergoing esophagectomy, and it might be effective in reducing infectious complications related to the surgical procedure.

Abstract
The expression of MUC1 and MUC2 mucin peptide core antigens in gastric carcinomas was studied by immunohistochemistry to determine correlations with TNM stage and histo-pathological classifications as well as a possible prognostic impact. Paraffin-embedded specimens from 128 gastric carcinomas with a minimal follow-up of 5 years were immunostained. In addition to a polyclonal antiserum generated against polymorphic epithelial mucin (MUC1) from human milk, 2 monoclonal antibodies (MAbs), HMFG2 (anti-MUC1) and 4FI (anti-MUC2), were applied. Reactivity of carcinomas was correlated with the classifications of the UICC (TNM), WHO and Laurén. Correlations with overall survival were analyzed using the Kaplan and Meier product limit method. MUC1 immunoreactivity was associated with an advanced pTNM stage. The demonstration of both mucin species (MUC1, MUC2) displayed a statistically significant correlation with tubular/papillary vs. signet-ring cell differentiation as well as with intestinal-type vs. diffuse-type of tumor growth according to Laurén. In particular, MUC2 was only rarely detectable in signet-ring cell and diffuse-type tumors. MUC1 correlated with poor prognosis in all cases and the subgroup of stage I tumors. According to the histopathological classifications, a similar result was observed in signet-ring cell and diffuse-type carcinomas. In contrast, MUC2 reactivity was associated with a favourable prognosis of intestinal-type carcinomas. In the non-neoplastic gastric mucosa, both peptide cores were recognized in the superficial epithelium, whereas parietal cells contained only MUC1, and intestinal metaplasia almost exclusively MUC2 antigens. We conclude that the mucin peptide core antigens are suitable markers for the tubule-rich gastric carcinomas, which may in part be derived from intestinal metaplasia. In addition, MUC1 may exert a prognostic relevance and appears to be involved in the progression of diffuse-type tumors.

Abstract
PURPOSE As previously shown, antibody treatment increased survival of patients with resected colorectal cancer of stage Dukes' C. Since the 5-year analysis was criticized because of the wide range (2.7 to 7.5 years) of follow-up time, we performed a 7-year analysis with only four of 189 patients monitored for less than 5 years. PATIENTS AND METHODS A total of 189 patients with resected Dukes' C colorectal cancer were randomly allocated to infusions of a total of 900 mg 17-1A antibody, 500 mg postoperatively followed by 4 monthly doses of 100 mg (n=99), or to observation only (n=90). Primary end points were overall survival and disease-free interval. Patients were stratified by a dynamic randomization according to center, sex, location of tumor, number of affected lymph nodes, and preoperative carcinoembryonic antigen concentration. RESULTS Randomization produced balanced distribution of risk factors. After 7 years of follow-up evaluation, treatment had reduced overall mortality by 32% (Cox's proportional hazard, P < .01; log-rank, P=.01) and decreased the recurrence rate by 23% (Cox's proportional hazard, P < .04; log-rank, P=.07). The intention-to-treat analysis gave a significant effect for overall survival (Cox's proportional hazard, P < .01; log-rank, P=.02) and disease-free survival (Cox's proportional hazard, P=.02; log-rank, P=.11 ). While distant metastases were significantly reduced (Cox's proportional hazard, P=.004; log-rank, P=.004), local relapses were not (Cox's proportional hazard, P=.65; log-rank, P=.52). This differential effect of 17-1A antibody on disseminated isolated tumor cells versus occult local satellites may explain the increased significance seen in the overall survival. CONCLUSION The now-matured study shows that 17-1A antibody administered after surgery prevents the development of distant metastasis in approximately one third of patients. The therapeutic effect is maintained after 7 years of follow-up evaluation.

Abstract
For evaluation of the prognostic relevance of p53 expression in gastric cancer, the immunohistochemical tissue status of 133 primary gastric cancer patients was investigated for p53 expression and the association between p53 tissue status and clinicopathological parameters was analyzed. P53 immunoreactivity was detected in the nuclei of cancer cells in 35 cases (26.3%). The nuclear p53 immunoreaction was closely associated with tumor location, lymph node metastasis, and curability. Tumors with positive p53 stain reactions frequently metastasized to lymph nodes (metastatic rate: 91.4%) in contrast to tumors with negative p53 stain reactivity (71.4%, P = 0.021). Immunohistochemical analysis of primary gastric cancer appears to be an accurate and simple method of screening for p53 expression. In combination with common prognostic parameters, determination of p53 tissue status might help to detect prognostically unfavorable subgroups of gastric cancer patients.

Abstract
OBJECTIVE To correlate variables recorded perioperatively with morbidity and mortality in an attempt to assess the predictive value of these variables for the outcome of individual patients. DESIGN Prospective study. SETTING Teaching hospital, Germany. SUBJECTS 6304 consecutive patients admitted for operation. INTERVENTIONS Recording of American Society of Anesthesiologists (ASA) class, age, sex, operation class (Hoehn), anaemia, hypertension, bronchopulmonary disease, diabetes mellitus, renal failure, major gastrointestinal disease, type of anaesthesia, operation (and whether emergency or elective), and duration of operation. All these factors were subjected to logistic regression analysis. MAIN OUTCOME MEASURES Odds ratio (OR), sensitivity, specifity, and positive and negative predictive values. RESULTS We studied 6304 patients of whom 140 died postoperatively and 1432 developed complications from which they survived. The variable that had most influence on the risk of postoperative complications was the ASA class (ASA class 4, OR 4.2, and ASA class 3, OR 2.2) followed by the severity of the operation (OR 1.86). An uncomplicated course was correctly predicted in 96%, but complications were correctly predicted in only 16%. The positive predictive value was 57%, and negative predictive value 80%. CONCLUSIONS Despite the fact that we considered a large number of variables we were unable to predict the risk of complications for individual patients with any accuracy.

Abstract
After carrying out the first free vein graft transplantation on an aneurysm of the axillary vein by Lexer in 1907, many attempts were made to reconstruct arterial injuries with direct vascular suture technique or vein graft transplants during the Balkan War (1912) and the First World War (1914-1918). Hans von Haberer gained wide experience in the reconstructive surgery of traumatic aneurysms at the Department of Surgery at the University of Innsbruck. During this period, he operated on a total of 201 vascular aneurysms, mainly using a direct circular vascular suture technique. In 1914, von Haberer described the first reconstruction of a carotid aneurysm. First experiences with vein bypasses were made, but not pursued in the following years.

Abstract
Hans von Haberer (1875-1958) gained wide experience in the reconstructive surgery of vascular aneurysms at the universities of Innsbruck, Graz, Düsseldorf and Cologne. In this period he operated on 421 vascular aneurysms--including 30 carotid aneurysms--mainly by means of direct circular vascular suture. In 1914 von Haberer described the first repair of a carotid aneurysm. Therefore he is the pioneer of reconstructive carotid surgery. Based on detailed clinical and operation reports on approximately 16,000 cases, written by Hans von Haberer between 1904 and 1949, and on the contemporary literature, we describe his experience in vascular surgery.

Abstract
BACKGROUND Palliative, minimal invasive treatment of rectal cancer is advocated in patients with advanced and incurable disease or poor clinical condition and in those who refuse radical surgery. Several methods have been used during recent years. We report our experience with palliative transanal endoscopic microsurgery. MATERIALS Between 1983 and 1995, 29 patients underwent transanal endoscopic microsurgery for palliation. Eleven patients had advanced malignant disease, nine were in poor clinical condition, and nine repeatedly refused radical surgery. RESULTS Intraoperatively one severe complication, an intra-abdominal perforation, occurred. The morbidity rate was 14%. Postoperatively, clinical signs were abolished or improved in all cases. Only three patients required further palliative resections after initial symptom relief. CONCLUSIONS Transanal endoscopic microsurgery is a successful approach in the palliative treatment of rectal cancer. The technique enables complete resection of rectal tumors. Although anesthesia is needed, the morbidity is low, even in patients with poor clinical condition.

Abstract
OBJECTIVE The effects of the different surgical approaches (transhiatal esophagectomy and right-sided transthoracic esophagectomy) on perioperative cardiopulmonary function in the surgical treatment of esophageal carcinoma are discussed controversially and have not yet been evaluated. METHODS In a prospective randomized study including 32 patients, we investigated the effects of the surgical approach (blunt dissection (n = 16) versus transthoracic en-bloc resection (EB) (n = 16)) in the treatment of esophagus carcinoma on perioperative cardiopulmonary function. The following parameters were measured in all patients: cardiac index (CI), mean arterial pressure (MAP), central venous pressure (CVP), mean pulmonary artery pressure (MPAP), pulmonary capillary wedge pressure (PCWP), intrapulmonary shunt (QS/QT), arterio-alveolar (aaDO2), arterio-venous oxygen pressure difference (avDO2), and blood gas analyses. Time of measurement were: after induction of anesthesia, beginning and end of esophagus resection, end of surgery, 1 h postoperatively, and then every 12 h until the third postoperative day. RESULTS Compared to blunt dissection, en-bloc esophagectomy was found to be associated with a transient deterioration of pulmonary function during one-lung ventilation in the left-lateral position, which could already be compensated for during the intervention. No other significant differences in cardiopulmonary effects were seen between the two surgical techniques. The incidence of postoperative complications was identical in both groups. CONCLUSIONS The results of our study show that en-bloc resection is only associated with an increased intraoperative pulmonary strain that is completely compensated during the operation and that there is no difference in cardiopulmonary functions between the two techniques in the postoperative course.

Abstract
The data from 1050 patients who had undergone colorectal carcinoma resection at the University of Cologne between 1976 and 1990 were studied. The aim of the study was to determine the concomitant effects on survival of several patient characteristics (sex, age, tumour localization, blood transfusion) and histopathological variables (Dukes' staging). We first calculated survival rates, both including and excluding post-operative mortality. We set up a hierarchical log-linear model for the detection of relationships between selected crossclassified categorial variables. We then used Cox's proportional hazard regression method to study the relationship between survival and different prognostic patterns. Dukes' staging was shown to be a highly discriminating factor in survival (P<0.001). Survival rates were better in women (P<0.001), and better for younger patients (<70 years; P<0.001). Tumour site (colon; P = 0.0362) and blood transfusion (P = 0.0857) also correlated with survival.

Abstract
PURPOSE To report progress in the development of a new minimally invasive surgical technique for aortobifemoral grafting utilizing gasless videoendoscopy. METHODS In an experimental study, aortobifemoral Dacron vascular prostheses were implanted in 20 human cadavers using videoendoscopic techniques in both transperitoneal and extraperitoneal approaches. Rather than inducing pneumoperitoneum, the abdominal wall was elevated with an electrically powered lifting system. RESULTS Each approach was utilized in 10 cadavers for implantation of 20 aortobifemoral grafts under endoscopic guidance in a gasless field. Average operative time for transperitoneal approach was 3.8 hours (range 3.0 to 5.5), slightly less than the average 4.1 hours (range 3.0 to 6.0) for the extraperitoneal access. Both access routes provided adequate visualization of the operative field. CONCLUSIONS Advantages of gasless endoscopy include the use of conventional instruments and the potential benefits associated with a minimally invasive approach. Optical magnification facilitates suturing of the femoral anastomosis, improves examination of the vascular walls, and allows a more accurate suturing technique.

Abstract
In order to assess the impact of surgical trauma involved in the therapy of esophageal carcinoma on the cellular immune system, a perspective study was performed involving perioperative hematological parameters. The activity of natural killer cells and the serum concentrations of interleukin-2, interleukin-6 and TNF-alpha were measured in 12 cases of transmediastinal dissection and 10 cases of transthoracic en bloc esophageal resection and compared to values of a control group of thoracic and abdominal surgical patients with non-malignant maladies. Natural killer cells assume a central role in the non-specific immunological response in tumor patients. Their main function is the destruction of tumor cells via cytotoxic activities amplified by the release of interleukin-2 and TNF-alpha. Natural killer cell activity was measured prior to surgery and on postoperative days 4 and 10 using a standardized europium chloride release assay, utilizing K562 target cells. Lymphokines interleukin-2, interleukin-6, and TNF-alpha were also measured on postoperative days 1 and 7 using standardized ELISA assays. The activity of natural killer cells in our patient group sank significantly (P < 0.05) on postoperative day 4 and likewise in the control group and both study groups, activity sank to the original values. In the control group, natural killer cell activity averaged 45% of preoperative values, in comparison with an average of 63% following transmediastinal esophageal carcinoma resection (one cavity procedure), and transthoracic en bloc resection (two cavity procedure). On postoperative day 10, all groups displayed a significant reacceleration of natural killer cell activity (P < 0.05). Whereas transthoracic en bloc resection patients only reached 61% of preoperative values, transmediastinal dissection patients assumed 75%, and 77% was achieved by control group members. Transthoracic en bloc resection of the esophagus led to a more extreme reduction in cytotoxic cellular activity owing to the greater surgical trauma. Suppression of the immunological tumor resistance, especially in the vulnerable perisurgical phase, can have an indirect negative effect on the manifestation risk of hematogenic metastases owing to intraoperative tumor cell dissemination resulting from tumor manipulation and may thus be prognostically relevant.

Abstract
In a prospective clinical study we examined whether bronchoscopically controlled suctioning is preferable to the blind suctioning of mucus aspirates for bacterial identification of intensive care unit patients with pneumonia. Forty patients with clinical and radiologic signs of pneumonia underwent both bronchoscopically controlled and blind endotracheal lavage. Bronchoscopically controlled suctioning did not demonstrate greater sensitivity for identifying organisms than the results obtained from blind suctioning (58 organism were bronchoscopically identified, compared to 57 organisms identified by blind suctioning; p = 0.32, NS). Arterial and mixed venous partial oxygen pressure and shunt also showed no significant differences 15 minutes before and after examination, nor did the blood pressure or pulse. The use of four of the bronchoscopes resulted in preinterventional contamination with Pseudomonas. Bronchoscopically controlled lavage shows no advantages over blind endotracheal lavage for diagnosing pneumonia. Blind suctioning with single-use sterile catheters can be done more quickly and inexpensively with fewer personnel and a lower complication rate.

Abstract
Quality of life (QL) after the "curative" resection of non-small cell bronchogenic carcinoma was assessed by patients using the EORTC QL questionnaire (QLQ) and by a psychologist using the Spitzer Index. Quality of life was assessed in 52 patients on one occasion 12 months postoperatively and in 20 patients regularly starting with a preoperative assessment. Self- and external evaluation showed a significant correlation (r = 0.41), but QL was assessed as being higher by the external observer. After surgery it was mainly affected by restrictions related to physical activities, job and household tasks, and disease symptoms, whereas limitations in emotional, social, and financial domains were found less frequently and less severely. Of the different medical (surgical procedures, tumor recurrence) and social factors (sex, marital and employment status), only tumor recurrence was determined to have a significant and negative influence on postoperative QL (P < 0.02). When compared to the preoperative assessment, QL had deteriorated on discharge from hospital but was restored within 3-6 months postoperatively in disease-free patients.

Abstract
Submucosal tissue oxygen tension (PtO2) was measured in 20 patients with cervical esophagogastrostomy after resection of esophageal carcinoma, using a Clark-type oxygen electrode. The mean gastric baseline PtO2 was 54.6 +/- 10.7 mm Hg. Following ligature of the vasa brevia and the left gastroepiploic artery PtO2 decreased to 45.8 +/- 9.9 mm Hg, ligature of the left gastric artery caused a decrease to 34.2 +/- 9.7 mm Hg and resection of the lesser curvature and pulling up of gastric tube led to 25.5 +/- 9.0 mm Hg. Clinical value and practicability of intraoperative PtO2 measurements could be proven.

Abstract
BACKGROUND Melphalan administered by isolated hyperthermic perfusion of the affected limb is an accepted treatment for malignant melanoma of the extremities. In contrast, pharmacologic and phase I studies suggest that, because of its high uptake, mitoxantrone may give even better local control, but data on survival, onset of metastases, and local and systemic toxicities have not yet been reported. METHODS A matched-pairs comparison was performed to examine differences in the tolerability and effectiveness of isolated hyperthermic extremity perfusion with mitoxantrone (n = 44) and melphalan (n = 44) in high risk and locoregionally (P < 0.41) metastatic malignant melanoma. Criteria evaluated were local and systemic complications, and recurrence-free and overall survival. RESULTS Local complications, such as delayed wound healing, were more frequent in the mitoxantrone (27.9%) than in the melphalan group (9.8%) (P < 0.05). Systemic toxicity, in particular bone marrow toxicity, was also more severe with mitoxantrone (78.6% versus 15.4%, P < 0.001). Hepatotoxic effects were more frequent among patients in the melphalan group who were older and has lower tissue perfusion temperatures (P < 0.05). There was no difference between the two groups in overall or recurrence-free survival (P < 0.41). CONCLUSIONS Local and systemic toxicity seem to be higher with mitoxantrone. Survival rates were similar with both drugs. The data obtained suggest a randomized phase II study with an appropriate number of patients.

Abstract
Experimental studies were performed to investigate further the effects of immunotherapy with Propionibacterium avidum KP-40 on thymocyte proliferation, maturation and emigration in BALB/c-mice. Thymus weight and thymocyte counts, especially cells presenting the immature or cytotoxic/suppressor phenotype were significantly increased. Due to enhanced emigration, peripheral blood lymphocyte and monocyte counts as well as expression of activation markers were significantly upregulated. The antimetastatic effect of Propionibacterium avidum KP-40 was demonstrated in BALB/c-mice, where RAW 117-H10 lymphosarcoma liver colonization was significantly reduced after immunostimulation. Clinical investigations proved that surgical treatment of colorectal carcinoma induced an evident decrease of peripheral blood lymphocytes as compared with preoperative counts. However, single preoperative Propionibacterium avidum KP-40 administration induced a considerable increase of peripheral white blood cell counts, especially lymphocytes. Clinical effects of preoperative immunostimulation by Propionibacterium granulosum KP-45 were investigated in a prospective randomized trial in colorectal carcinoma patients. Positive effects on survival time, local tumor recurrence and distant metastasis could be demonstrated in stages I and II, whereas no advantage of immunotherapy was found in advanced stages III and IV. A recent prospective randomized clinical trial was initiated on the quality of life of colorectal carcinoma patients. Three months after surgical treatment negative effects could not be determined after immunotherapy. Quality of life even proved to be better in patients with abdominoperineal resection as compared to non Propionibacterium avidum KP-40 treated control patients.

Abstract
Tuberculosis is extremely rare in Germany today. Diagnosis of extrapulmonary tuberculosis has proved to be particularly difficult and a correct diagnosis can take months. The danger of fatality is high. In the case of a 29 year old male paraplegic patient suffering from enteral tuberculosis, diagnosis was possible only after several weeks of onward observation, extreme physical degeneration and finally, a laparotomy.

Abstract
Sphincter saving resections (SSR) are performed with increasing frequency in carcinoma of the lower and middle third of the rectum. In this retrospective study local and distant recurrence and survival were compared to abdominoperineal resection (APR). In 71 women and 71 men (mean age: 64 years) with a primary adenocarcinoma between 5 and 10 cm from the anal verge 89 SSR, and 53 APR, were performed (Dukes stages--SSR--A 19%; B 30.3%; C 50.7% vs APR--A 15%; B 45.3%; C 39.6%). Patients have been followed up for a minimum of 24 months (mean time 62 months). There were no differences in intraluminal diameters of the tumours in each operative procedure. The distal tumour-free distance was more than 6 cm in 52% after APR (SSR: 10%) and less than 3 cm in 43% after SSR. Survival was not different between procedures in Dukes stages A and B. A survival advantage for patients with Dukes C carcinoma after APR did not reach statistical significance. No differences in distant spread were found for SSR (Dukes stage A 0%; B 7%; C 18%) and APR (Dukes stage A 0%; B 8%; C 14%) for local recurrence in Dukes stages A and B after SSR (A and B 0%) and APR (A 0%; B 8%) whereas a significant increase in local recurrence rate was seen in Dukes stage C after SSR (24% vs, APR 5%). Although a further resection could be performed in almost all of these patients a negative effect of local recurrence on survival occurred (25.4 months with and 80 months without local recurrence). While SSR seems to be favourable in Dukes stages A and B, APR should be considered in carcinoma of the lower and middle third of the rectum with lymphatic spread. Effective preoperative staging determines selection of the appropriate operation.

Abstract
Postoperative radiation therapy following curative resection of squamous cell carcinoma of the esophagus was investigated in a prospective randomized study. A group of 33 patients received postoperative radiation therapy and were compared to a control group of 35 patients treated by surgery alone. No statistically significant differences were noted between the two treatment groups concerning overall and disease-free survival rates. Postoperative irradiation significantly increased the incidence of fibrotic strictures of the esophagogastric or esophagocolonic anastomoses and caused a delayed recovery of patients quality of life. Based on these results, we believe that postoperative radiation therapy alone cannot be advocated as a adjuvant therapy following curative resection of squamous cell carcinoma of the esophagus.

Abstract
The effects of pyloroplasty following subtotal oesophagectomy and gastric substitution with cervical oesophago-gastric anastomosis were studied in a prospective randomized trial. 52 patients received extramucosal pyloroplasty and were compared to a control group of 55 patients, in whom no drainage procedure was performed. 6 patients died postoperatively. One of these patients died following the insufficiency of pyloroplasty. The other causes of death were not related to the performance or non-performance of pyloroplasty. Regarding to patients subjective self-assessment of abdominal discomfort and radiologic emptying of the gastric tube no statistical significant differences between both groups were noted 2 weeks and 6 months postoperatively. Two patients with pyloroplasty, but no patient of the control group, suffered 12 months postoperatively from severe vomiting due to fibrotic stricture of the pylorus. The results of this study suggest, that usually no pyloroplasty should be performed following subtotal oesophagectomy and interposition of a gastric tube with oesophagogastric anastomosis in the neck.

Abstract
OBJECTIVE To describe our experience with three cases of leiomyosarcoma of the inferior vena cava, and summarise current methods of diagnosis and treatment. DESIGN Descriptive study. SETTING University hospital, Germany. SUBJECTS 3 Patients with histologically confirmed leiomyosarcoma of the inferior vena cava. INTERVENTIONS Resection, with or without vascular reconstruction. MAIN OUTCOME MEASURES Morbidity and mortality. RESULTS Case 1 was diagnosed on magnetic resonance imaging, the tumour was resected, and the vena cava replaced with a polytetrafluoroethylene (PTFE) graft. She made an uncomplicated recovery and was well and free of symptoms 10 months later. Case 2 was diagnosed at operation (the differential diagnosis on computed tomography was a retroperitoneal tumour), the tumour was resected, and the defect oversewn. She made an uneventful recovery and was well and free of symptoms 14 months later. Case 3 was diagnosed at operation (a diagnosis of pancreatic cancer had been made preoperatively), the tumour was resected, and the defect oversewn. She was well and free of symptoms 10 months after operation. CONCLUSIONS Magnetic resonance imaging is superior to computed tomography in the diagnosis of leiomyosarcoma of the inferior vena cava. The treatment of choice is resection; small defects can be closed by suture or PTFE patch, and large defects by PTFE prostheses. Reported resectability is 40% to 60%, but the prognosis is poor; the local recurrence rate is about 36%, most patients are dead within 2.5 years, and the 5-year survival is 30%. Chemotherapy and radiotherapy will give some degree of palliation, but do not affect the outcome.

Abstract
A retrospective study of the possible value of standardized follow-up examinations was undertaken in a group of 251 patients (163 men, 88 women; mean age at diagnosis 58 [33-78] years) who had undergone putatively curative gastric resection for adenocarcinoma between 1.1. 1978 and 31. 12. 1987 and had survived at least 3 months after the operation. 113 patients (45%) regularly had follow-up examinations according to a standardized diagnostic protocol, 67 (27%) only irregularly, while 71 (28%) had none. Follow-up examination revealed tumour recurrence in 53 patients (30%), which in 18 (34%) was still asymptomatic. In one of these patients resection of the recurrence was again undertaken with curative intent, a palliative operation was performed in five, chemotherapy in seven, three received radiotherapy and 37 were treated purely symptomatically. The results do not indicate that the survival rate was improved by the standardized follow-up protocol and it is concluded that symptom-oriented and individualized follow-up examination without standardized protocol is sufficient in this type of case, except for scientific purposes.

Abstract
Adhesion of bacteria and of metastasizing tumour cells have much in common, especially the participation of lectins in this process. In the future it might be possible to inhibit the metastatic process and bacterial adhesion by blocking with lectins specific for appropriate (oligo) saccharides or glycoconjugates. Initial clinical trials are very promising.

Abstract
The viability of porcine collagenase-prepared islet preparations (n = 16) was classified by 31P-NMR spectroscopy, staining by neutral red and trypan blue, and in vitro insulin secretion following glucose challenge. Vital islets exhibited a phosphate diester/phosphate monoester (PDE/PME) ratio of 0.5-0.9, a staining score of 18-30 and an insulin secretion responding well to glucose challenge. Damaged islets performed at a PDE/PME of 0.2-0.49 and a staining score of 9-17 and necrotic islets had 0.0-0.49 and a staining score of 9-17 and necrotic islets had 0.0-0.19 and 0-8, respectively. The islets of the latter two groups did not adequately respond to glucose. The in vivo function following autotransplantation of these islets into the spleen was investigated in five recipients of more than 3000/kg vital islets of which 4 expressed daily normoglycemia (< 200 mg%), normalized intravenous glucose tolerance (K = -2.21), and a prolonged survival (mean +/- SD) of 167 +/- 12 days compared to five recipients of > 3000/kg damaged islets (K = -0.814) (P = 0.0017) and a survival of 86 +/- 21 days (P = 0.0096). It is suggested that 31P-NMR spectroscopy is a valuable and practical method to predict islet graft viability prior to transplantation in order to assure good graft function in the recipient.

Abstract
The outcomes of 190 patients in whom a non-small-cell bronchogenic carcinoma had been resected with curative intent in the Department of Surgery, University of Cologne, between 1. 1. 1977 and 31. 12. 1987 were analysed retrospectively. Sixty-seven (35%) of these patients underwent regular, 64 (34%) irregular, and 59 (31%) no standardized follow-up programmes. During follow-up procedures tumour recurrences were detected in 33 patients (25%). Thirteen (39%) of these recurrences were completely asymptomatic at the time of diagnosis. Three recurrences (9%) were resected with curative intent, but the patients died between 14 and 17 months later due to recurrent disease. Seven recurrences (21%) were treated by radiotherapy, three (9%) by chemotherapy, and 20 patients (61%) received no oncologic therapy. The survival rates after diagnosis of recurrence were not affected by the type of treatment or by the presence of clinical symptoms. There is no evidence that long-term results following resection of non-small-cell bronchogenic carcinoma can be improved by regular and standardized follow-up programmes. The observed incidence of postoperative pulmonary disorders and the patients' self-assessment underline the necessity for postoperative care after resection of bronchogenic carcinoma. Apart from clinical studies, follow-up should primarily focus on individual symptoms and should no longer include standardized investigations in asymptomatic patients except occasional X-ray checks of the thorax.

Abstract
During the period March 3, 1992 to September 30, 1993 36 video-assisted thoracoscopic operations were performed at the Surgical Department of the University of Cologne. In 12 cases wedge resection of peripheral pulmonary nodules were carried out. Two of the patients underwent video-assisted thoracoscopic lobectomy of the left lower lobe due to peripheral primary bronchogenic carcinoma. In 6 cases biopsy of the lung or pleura was undertaken. Further indications were partial pleurectomy and resection of blebs (n = 12). Pleural effusion was drained under thoracoscopic vision twice. No intraoperative complications occurred. Two patients proceeded to thoracotomy after persistence of pneumothorax following thoracoscopic pleurectomy. The postoperative course of the remaining patients was uneventful and was especially characterized by the reduction in pain and disability. In accordance to the experience of other authors we believe that thoracoscopic surgery is a method with a promising future. Further investigations have to evaluate indications, different techniques, and long term results.

Abstract
Over the past decade various clinical trials have used monoclonal antibodies as therapeutic agents against solid tumours. No consistent pattern of response or improved survival has yet emerged although antigenic heterogeneity and insufficient accessibility of cells in advanced tumours have been offered as explanations for these failures. We designed a study in which a monoclonal antibody was used to target minimal residual disease in an early stage of tumour cell dissemination in patients with colorectal cancer. Only patients in Dukes' stage C who had undergone curative surgery and were free of manifest residual tumour were admitted. 189 patients with colorectal cancer of stage Dukes' C were randomly assigned to an observation regimen or to postoperative treatment with 500 mg of 17-1A antibody, followed by four 100 mg infusions each month. A balance of risk factors in the two groups was achieved by dynamic randomisation procedure. After a median follow-up of 5 years, antibody treatment reduced the overall death rate by 30% (Cox's proportional hazard, p = 0.04, log-rank p = 0.05) and decreased the recurrence rate by 27% (p = 0.03, p = 0.05). The effect of antibody was most pronounced in patients who had distant metastasis as first sign of a relapse (p = 0.0014, p = 0.002), an effect that was not seen for local relapses (p = 0.74, p = 0.67). Toxic effects of 17-1A antibody were infrequent, consisting mainly of mild constitutional and gastrointestinal symptoms. During 371 infusions four anaphylactic reactions were seen, all controllable by intravenous steroids and none necessitated admission to hospital. Adjuvant therapy with 17-1A antibody extends life and prolongs remission in patients with colorectal cancer of Dukes' stage C.

Abstract
In order to improve the perioperative resistance to the spread of cancer during operation the effect of preoperative stimulation of the immunesystem by Propionibacterium granulosum KP-45 was investigated in patients with colorectal carcinoma. In a prospective randomized trial 101 patients were allocated to either treatment (n = 51) or control (n = 50). In the treatment 10 mg of Propioni bacteria were administered intravenously between the seventh and third day prior to surgical treatment. At the time of operation 21 tumours were classified as stage I (treatment n = 12, control n = 9), 22 as stage II (treatment n = 10, control n = 2). Postoperatively wound infections requiring treatment were more prevalent in the control group (n = 4) than in the treated group (n = 0). All patients were subsequently followed up for 76 months. For stage I carcinoma the survival rates, excluding perioperative deaths, were 91% in the treated and 63% in the control group respectively. One case of tumour metastasis was seen in the control group. For stage II carcinoma the survival rate was 90% for the treated group with distant spread in 1 case and 45% in the control group where the rate of recurrence was 55%. For stages III and IV there was no statistically significant difference in survival between the treated and the control groups.

Abstract
Three different methods of preoperative bowel preparation were tested in a prospective randomized trial examining efficacy and morbidity. In all, 163 patients were treated by gut irrigation with Ringer's lactate, Prepacol or polyethylene glycol (PEG). Fluid retention, cleansing effect, postoperative complications and subjective acceptance were documented. Relevant weight gain and decrease in haematocrit indicating fluid retention were seen only after the use of Ringer's lactate. There were no significant differences in bowel cleansing. In the Prepacol group the postoperative complication rate was significantly increased. Prepacol was tolerated best, with few side-effects. PEG was better tolerated than Ringer's lactate, but vomiting occurred in 2 and 21 per cent of patients respectively. PEG is most suitable for bowel preparation in patients undergoing colorectal surgery.

Abstract
In a consecutive series of 90 hepatic resections for colorectal liver metastases which were performed during a 10-year period at one institution, the influence of patient's age on surgical strategies and postoperative results was investigated. The mean age of all patients was 61 +/- 11 years with a range from 27-78 years; 19 patients (21%) were younger than 50 years and 18 patients (20%) were older than 70 years. Thirty-six (40%) major and 54 (60%) minor hepatic resections were performed. The postoperative complication rate was 26% and resection mortality 3%. Estimated overall median survival time was 27 months, operative mortality included. 1-, 3-, and 5-year survival rates were 78%, 45%, and 32%, respectively. Although there is some suggestion that selection criteria are more aggressive in younger patients, neither surgical procedures nor postoperative results were found to be determined by the numeric age of the patient in a significant way.

Abstract
A technique for the closure of upper median sternotomy with absorbable polyglycolid acid sutures is described. In a consecutive series of 130 refixations, no major complications occurred. After a mean follow-up period of 66 +/- 61 months, the long-term results concerning sternotomy closure were determined in 86 patients: 84 (98%) sternotomies were completely consolidated, in 75 cases (87%) without any dislocation and in nine cases (11%) with a minor dislocation in the transverse osteotomy. In two patients (2%) who had received postoperative radio- and chemotherapy, an isolated pseudarthrosis of the transverse osteotomy was observed, whereas the median sternotomy was consolidated completely. As a result of our clinical experience, we consider the closure of partial upper sternotomy with absorbable polyglycoid acid sutures as a practical and safe technique.

Abstract
In a prospective randomized study, one- and two-layer anastomoses were compared following subtotal oesophagectomy and gastric substitution with cervical oesophagogastric anastomosis. After 54 one- and 53 two-layer procedures the rates of anastomotic leakage were the same (19 per cent). After a mean follow-up of 44 weeks, 13 of 51 patients (25 per cent) undergoing one-layer anastomosis and 28 of 50 (56 per cent) having the two-layer procedure complained of cervical dysphagia and required dilatation. The anastomotic strictures were fibrotic in 11 of 51 patients (22 per cent) undergoing one-layer anastomosis and in 24 of 50 (48 per cent) receiving the two-layer operation. Strictures were malignant in two and four patients (4 and 8 per cent) respectively. The lower incidence of fibrotic stricture following one-layer anastomosis was significant (P < 0.01), but not that of malignant stricture. With comparable leakage rates, one-layer anastomosis is superior to the two-layer procedure because of the lower incidence of fibrotic stricture.

Abstract
From January 1, 1981 to January 1, 1992 a total of 30 liver abscesses were treated in the University Clinic for Surgery in Cologne. 23 patients underwent an primary operative treatment and seven patients received a controlled guided percutaneous drainage. During the observation period four patients (13.3%) died by the effect of the liver abscess. 20 patients (66.7%) were subjected to clinical, laboratorical and computertomographical post examinations. The primary rate of operation success amounted to 47.8%, that of controlled guided percutaneous drainage of 42.8% (NS). The secondary success rate (that means after successful operative reintervention) amounted to 86.9% by the operative and to 85.7% by the percutaneous drainaged cases. During the post examination no relapse was determinated. Larger or chambered liver abscesses as well as extrahepatic spreading required operative drainage and, in cases of multifocal spreading, a resection with concomitant antibiotics. In case of solitary abscesses the controlled guided percutaneous drainage is the least harmful and low-prices method.
