Abstract
OBJECTIVES Preliminary results of photodynamic therapy (PDT) of bile duct cancer have shown astonishingly good results in the reduction of cholestasis, improvement of quality of life, and even prolongation of the survival time. Unfortunately, the existing dye laser systems are large and costly, and their maintenance is expensive. Therefore, we investigated the feasibility of a diode laser system for PDT of nonresectable bile duct cancer. METHODS Eight patients with nonresectable bile duct cancer were treated. Forty-eight hours after i. v. application of 2 mg/kg body weight of Photosan-3, light activation was performed by a transpapillary (four patients) or percutaneus (four patients) access. We used a cylindrical diffusor tip and illuminated using a wavelength of 633+/-3 nm and a total energy of 200 J/cm2. All patients were additionally provided with bile duct endoprostheses after PDT. RESULTS Four weeks after initial PDT all patients showed a marked reduction of bile duct stenosis. The median serum bilirubin value declined from 5.8 mg/dl (2.0-10.1) to 1.0 mg/dl (0.8-4.4). The median survival time at the time of writing is 119 days (52-443). Five patients are still alive. In four patients we could change from percutaneous to transpapillary drainage after PDT, two patients showed infectious complications. CONCLUSION PDT with the diode laser system seems to be effective in reducing malignant bile duct stenosis. This treatment is minimally invasive and has a low specific complication rate. Randomized, controlled studies comparing PDT with the insertion of endoprostheses and long term follow-up of results are needed to confirm the promising short term results.

Abstract
BACKGROUND Data concerning the association of juxtapapillary duodenal diverticula (JPDD) with biliopancreatic disorders are inconsistent, but an association between bile duct stones and JPDD is widely accepted. The aim of this study was to investigate the frequency of JPDD and its association with biliopancreatic disorders in patients undergoing ERCP. METHODS A retrospective analysis was conducted of 5497 consecutive ERCP procedures performed in 2925 patients. Matched-pair analysis yielded 350 pairs of patients with and without JPDD, matched for definite risk criteria such as age, gender, and indication for ERCP. RESULT The incidence of JPDD was 12%. Patients with JPDD were significantly older than patients without JPDD (71 vs. 62 years; p < 0.0019) and had a significantly higher bleeding rate after endoscopic sphincterotomy (8.8% vs. 4.8%; p = 0.039). The presence of JPDD correlated with gallbladder stones (29.4% vs. 20.8%; p = 0.039), bile duct stones (46% vs. 33.1%; p < 0.001), and recurrence of bile duct stones (6.6% vs. 1.4%; p = 0.002). There were no significant differences in frequency of acute and chronic pancreatitis as well as pancreas divisum. After multivariate logistic regression analysis, technically difficult ERCP, bleeding after endoscopic sphincterotomy, and bile duct stones remained as independent risk factors. CONCLUSION JPDD appears to be a risk factor for complications of endoscopic sphincterotomy and for gallbladder stones, bile duct stones, and their recurrence.

Abstract
BACKGROUND AND STUDY AIMS Endoscopic sphincterotomy (EST) is the standard procedure for gaining access to the common bile duct for removal of bile duct stones. However, the procedure is associated with both short-term and long-term complications. Recent reports have described the use of endoscopic papillary balloon dilation (EBD) as an effective and safe alternative to EST. We conducted a prospective randomized pilot study to compare the efficacy and short-term complication rates of these two established methods for removing uncomplicated bile duct stones. PATIENTS AND METHODS Sixty patients were randomly assigned to receive either EST (n = 30) or EBD (n = 30) prior to removal of bile duct stones (maximum size 20 mm, maximum number five). The patient groups were comparable with regard to sex and age ratios, the size of the stones (EST: mean 10 +/- 4.7 mm; EBD: mean 7 +/- 3.5 min; not significant) and the numbers of stones (EST: mean 1.8 +/- 1.5 mm; EBD: mean 1.6 +/- 1.1 mm; not significant). EBD was carried out using a balloon-tipped biliary catheter (Maxforce, Microvasive, Boston, Massachusetts, USA) with a maximum diameter of 24 Fr for 45-60 s. Bile duct stones were removed using Dormia baskets or retrieval balloons, or both. RESULTS The two methods were successful in all patients studied. Subsequent stone removal was possible in all 30 patients after EST (100%) and in 23 of the 30 who underwent EBD (77%), respectively (P<0.01). After conversion to EST, complete bile duct clearance was also achieved in the remaining seven EBD patients. The mean duration for the whole procedure was 17 +/- 12 min for EST and 29 +/- 15 min for EBD (not significant). Complications (WHO grades 2-4) were observed in five of the 30 EST patients (three cases of mild pancreatitis, two of hemorrhage) and in nine of the 30 EBD patients (three cases of cholangitis, four of mild pancreatitis, and two of severe pancreatitis), showing a trend toward higher complication rates in the EBD group. Postintervention hyperamylasemia was observed in six patients (three in each group). CONCLUSIONS The results of this prospective randomized pilot study indicate that EST is superior to EBD in terms of stone removal, duration of the procedure, and complication rates. EST will therefore continue to be the standard procedure for stone removal in the near future. Further studies will be needed in order to compare the longer-term results with EST and EBD.

Abstract
BACKGROUND Minilaparoscopy (ML) is being used increasingly in the diagnosis of liver disease. This is a prospective study of the accuracy and safety of ML compared with conventional laparoscopy (CL) in the diagnostic workup of liver disease. METHODS One hundred four patients with suspected liver disease were randomized either to undergo CL (n = 50) or ML (n = 54). CL was performed with a standard Storz laparoscope (Ø 11 mm, Storz GmbH, Tuttlingen, Germany) according to accepted guidelines. For ML a 1.9-mm small-diameter optical telescope was used (Richard Wolf GmbH, Knittlingen, Germany). In all cases, an attempt was made to obtain a liver biopsy specimen. RESULTS Laparoscopy could successfully be performed in 100 of 104 (96%) patients with simultaneous procurement of biopsy specimens of the liver. In 4 cases, postoperative adhesions prevented sufficient inspection of the liver and in another patient the technique was switched from CL to ML for the same reason. Minor self-limiting bleeding at the biopsy site was observed in 20% of CL and 15% of ML examinations. One patient in each group required surgery for uncontrollable bleeding from the biopsy site. The patients' subjective perception of the examination was comparable in both groups. Compared with CL, ML could be performed in a significantly shorter time (27 vs. 22 min, p < 0.05). Liver cirrhosis diagnosed during laparoscopy was histologically confirmed in 77%, independent of the method of examination. Cirrhosis was diagnosed by histology in 1 of 14 (7%) and 1 of 21 (5%) patients without macroscopic signs of cirrhosis. CONCLUSIONS Laparoscopy with a small diameter telescope in the workup of liver disease is comparable in terms of results to CL. Possible advantages of ML are a shorter examination time and a subjective impression of lower degree of invasiveness.

Abstract
Bleeding from varices outside the gastroesophageal region is a rare, but regularly reported complication of portal hypertension. The treatment differs from the management of esophageal and gastric varices. We present here a report on the diagnosis and treatment of bleeding jejunal and gallbladder varices in a man with portal hypertension caused by chronic calcifying pancreatitis. The patient was suffering from recurrent, frequent, and massive gastrointestinal bleeding from varices at the anastomotic area of a cholecystojejunostomy. For diagnostic purposes, we carried out percutaneous Duplex ultrasonography and push enteroscopy with the Doppler technique. The treatment of varices in this area is traditionally surgical. This is the first report of enteroscopic sclerotherapy being successfully carried out using cyanoacrylate to treat hemorrhage from jejunal and gallbladder varices. No clinical signs of gastrointestinal bleeding were observed during a follow-up period of seven months.

Abstract
BACKGROUND Several studies and our own results prove that endoscopic therapy in selected cases of benign adenomas is safe and technically feasible. In patients refusing surgery or patients with high comorbidity and poor physical health status, endoscopic resection is an excellent alternative. DISCUSSION The decision for endoscopic or surgical excision of adenomas is determined by general health status, histology, size, location, and depth of the lesion. In carcinoma of the papilla of Vater it is important to assess the tumoral ductal infiltration correctly to determine whether endoscopic resection is a viable option. Intraductal ultrasound is essential before initiating treatment and it therefore contributes to conservative therapy in patients with tumors of the papilla of Vater. Temporary placement of a short pancreatic duct stent may protect against pancreatitis and might allow more excessive ablation of adenomatous tissue, especially around the pancreatic duct orifice. After endoscopic sphincterotomy, biliary and pancreatic endoprostheses can be inserted easily in cases of obstructed pathways or cholangitis and pancreatitis due to tumor obstruction. Argon plasma coagulation can be used to treat oozing tumor hemorrhages or to vaporize tumoral residues after endoscopic snare resection. Endoscopic surveillance is essential after surgical or endoscopic resection of adenomas of the papilla of Vater.

Abstract
Disordered gastric motility occurs frequently in diabetes mellitus. Gastric emptying time is abnormal in about 50% of diabetic patients and delayed emptying time is known as an important cause for brittle diabetes in type 1 diabetes. We compared the rise in blood glucose after a standardized meal (oatmeal test) as a noninvasive screening test for diabetic gastropathy with the noninvasive measurement of gastric emptying time with ultrasound in type 1 and type 2 diabetic patients. The test result was considered pathological if the rise of blood glucose after an initial steady state did not reach 20 mg/dl in the first 20 min after the meal (prolonged blood glucose latency). We found a sensitivity of 90% (58.7-99.8) and a specificity of 100% (71.5-100) for the oatmeal test in type 1 diabetes in the gastropathy screening. In type 2 diabetes we found a sensitivity of 13% (1.5-38.3) and a specificity of 78% (60-90.7) (95% CI). In conclusion, the oatmeal test seemed to be a good, noninvasive screening test in diabetic gastropathy in type 1 diabetes, but has no diagnostic value in type 2 diabetes. The causes for such a difference may be due to a different postprandial blood glucose regulation in type 2 diabetes compared to the beta-cell-depleted type 1 diabetes.

Abstract
BACKGROUND Barrett's esophagus predisposes to cancer development. The diagnosis of dysplastic precursor lesions is impaired by problems of subjectivity. In the present study, DNA ploidy results of patients with Barrett's esophagus were related to the grade of dysplasia and to the progress of the disease. PATIENTS AND METHODS In 61 patients with Barrett's esophagus, DNA ploidy was determined by image cytometry on imprints. All biopsies (n = 145) were histologically examined for dysplasia distinguishing between low- and high-grade dysplasia, and dysplasia-negative. RESULTS A significant correlation (p < 0.001) between DNA ploidy and the grade of dysplasia was found, with 81% euploid DNA results in biopsies negative for dysplasia and 86% abnormal DNA patterns in biopsies with high-grade dysplasia. The subgroup of low-grade dysplasia showed a heterogeneous DNA ploidy. It is important to note that nearly 20% of biopsies classified dysplasia-negative contained abnormal single cells or abnormal stemlines regarding DNA content. In several cases, suspect DNA results caused a modified reclassification of dysplasia, and there were cases in which patients negative for dysplasia but positive for abnormal DNA ploidy developed dysplasia later on. CONCLUSION In patients with Barrett's esophagus, DNA ploidy by image cytometry is a suitable additive method for histological evaluation of dysplasia. It seems to be helpful in identifying patients at risk, perhaps before the development of clear dysplasia.

Abstract
BACKGROUND Plesiomonas shigelloides is a common pathogen in tropical regions, whereas it is rarely isolated in temperate climates. It is most often found in surface water and fish. During the last 10 years it was found to cause gastroenteritis 6 times in Ludwigshafen. Not all of these patients reported a trip to foreign countries. CASE REPORT A 54-year-old male patient was hospitalized after a trip to Malaysia with strong greenish watery diarrhea and chills. On physical examination we saw a dehydrated patient in severely reduced general condition. The stool frequency was 30/d. The laboratory examinations only showed elevated parameters of inflammation. Plesiomonas shigelloides was cultivated in the stool cultures. With appropriate substitution of fluid and electrolytes, and antidiarrheal therapy the patient resumed a normal diet without any complications. Three days later his bowel movements were normal and his general condition was greatly improved. We withheld antibiotic therapy because of the noncomplicated course of illness. CONCLUSION In Germany infections with Plesiomonas shigelloides are rare, an increase is observed because of increasing tourism to tropical regions. The course of infection is sometimes asymptomatic, but usually patients develop an acute gastroenteritis. Especially immunocompromised patients can show serious courses of infection. Plesiomonas shigelloides should be included in the differential diagnosis of acute gastroenteritis after journeys to tropical regions. Some of our patients, however, denied traveling to tropical regions. They also denied consuming seafood, which indicates a risk of infection in Germany. Still an infection with Plesiomonas shigelloides seems to be rare in northern European countries.

Abstract
Accurate staging of pancreatic malignancy is essential to properly plan appropriate therapy. The purpose of preoperative staging of intraabdominal malignancies is to identify patients in whom malignancies are unresectable and therefore would not be candidates for curative surgery. Routine preoperative evaluation of intraabdominal malignancies typically include abdominal helical computed tomographic (CT) scanning and/or ultrafast magnetic resonance (MR) imaging. In fact both investigations are considered mandatory for intraabdominal malignancies. But despite modern techniques a significant number of false negative results occur (more than 20%). This has led to the investigation of additional staging modalities to better identify patients with unresectable disease. In this purpose we present the case of a patient with pancreatic carcinoma. After preoperative imaging (ultrasound, endosonography and MRI) there was no evidence for metastatic disease (uT3uN1). He underwent laparoscopy and a hepatic lesion was detected, histologically consistent with a liver metastasis. In this patient an unnecessary laparotomy could be avoided. In conclusion laparoscopy is an important tool in the staging of intraabdominal malignancy for patients with locally advanced disease without signs of tumor spread in CT or MRT. It is a relatively simple, well-tolerated and safe procedure and decreases the rate of unnecessary laparotomies. It should be considered in all patients with pancreatic malignancy in whom laparotomy is planned, either to establish the diagnosis or before an attempt at curative resection.

Abstract
INTRODUCTION Laparoscopy plays an essential role in the diagnosis of hepatic diseases. During the past few years, minilaparoscopy (ML) has increasingly emerged as an alternative diagnostic method in this field. We hereby present the preliminary results of a randomized trial comparing ML with conventional laparoscopy (CL). PATIENTS AND METHODS 92 with suspected hepatic disease were randomized either to undergo CL (n = 47) or ML (n = 45). For CL, we used a Hopkins-laparoscope (Ø 11 mm, Storz, Tuttlingen) and ML was performed with a 1.9 mm small-diameter optic (Wolf, Knittlingen). RESULTS Laparoscopy with simultaneous liver biopsy could successfully be performed in 88/92 patients. ML could be performed in a significantly shorter time than CL (25 vs. 28 min, p < 0.05). Liver cirrhosis was diagnosed by laparoscopy in a similar proportion of patients (70% in CL, 56% in ML). In 76% of cases, histology confirmed macroscopic signs of liver cirrhosis. Cirrhosis was found in one patient of each group solely by histologic examination of biopsy specimens. The number of bleeding complications during CL equaled the proportion of hemorrhagias in the ML-group. DISCUSSION In the workup of hepatic disease, ML is a diagnostic tool comparable with CL. The fact that ML can be performed in significantly shorter time and seems subjectively less invasive might be an argument for a better acceptance by patients.

Abstract
The value of surgical laparoscopy for various therapeutic interventions has been well established. In recent years, the interest of gastroenterologists in this method has revived, since laparoscopy can provide additional information for the staging of oncological and liver diseases. The introduction of miniature lenses may have contributed to this process, and an increasing number of physicians are using minilaparoscopy due to its safety and easy handling. Surgical studies have mainly focused on the evaluation of laparoscopic ultrasound for the detection of liver and lymph-node metastases. In specialized centers, laparoscopic ultrasound is also used for the estimation of locoregional pancreatic tumor spread, but the diagnostic impact of the method, particularly in colorectal carcinoma, still remains to be determined. Remarkably, the number of publications from gastroenterology departments has tended to increase in comparison with last year's review.

Abstract
This study was performed to assess the role of additional diagnostic laparoscopy in the preoperative staging of patients with gastric cancer and pancreatic cancer prior to intended curative surgery. Furthermore patients with ascites of unknown origin were evaluated. 127 patients with primary solid abdominal tumors were eligible for evaluation; of those 66 patients had a gastric cancer and 61 a pancreatic cancer. Patients without histologically proven metastases proceeded to laparotomy. Ascites of unknown origin was the indication for performing a diagnostic laparoscopy in 23 patients. Metastases were detectable laparoscopically in 13 of 66 patients (20%) with gastric cancer. Intraoperatively metastases were evident in further 7 cases. In 14 of 61 patients (23%) with pancreatic cancer metastases were detected by laparoscopy and in further 5 patients intraoperatively. A peritoneal carcinosis was diagnosed laparoscopically in 17 of 23 patients with ascites of unknown origin. Preoperative staging by additional diagnostic laparoscopy proved effective in patients with gastric- and pancreatic cancer.

Abstract
OBJECTIVE The pathogenesis of stress ulceration in seriously ill patients is uncertain and the pathogenic role of Helicobacter pylori infection is unknown. We therefore assessed the seroprevalence of patients of a cardiosurgical intensive care unit (ICU) with clinically important stress ulcer bleeding. We compared this prevalence with a control group matched for this kind of surgical intervention, missing history of peptic ulcer disease, age and gender. DESIGN Prospective survey. SETTING Cardiosurgical ICU in a university teaching hospital. PATIENTS AND PARTICIPANTS Two thousand five hundred seventy cardiosurgical patients with intravenous ranitidine stress ulcer prophylaxis were screened for clinically important stress ulcer bleeding. Helicobacter pylori seropositivity was measured in all patients with a clinically important bleeding and in a control group of 245 consecutive cardiosurgical patients, matched for the kind of cardiosurgical intervention, age and gender. RESULTS In 56 of 2,570 (2.1%) patients signs of clinically important bleeding were seen. Endoscopical examination revealed stress ulcer bleeding in 42 cases. The incidence of stress ulcer bleeding was 1.6%. The seropositivity of the group with ulcer bleeding was 45.2 % whereas 62.4 % of the patients in the control group were Helicobacter pylori positive (p = 0.08). CONCLUSIONS Our results suggest that the Helicobacter pylori infection does not play a pathogenic role in stress ulcer bleeding. Prophylactic cure of Helicobacter pylori can not be recommended in this setting.

Abstract
BACKGROUND To assess the analgesic efficacy and side effects of buprenorphine and procaine in patients with acute pancreatitis. METHODS Forty patients (average age, 50 years; 23 male) with acute pancreatitis or an acute bout of a chronic pancreatitis were prospectively randomized to receive buprenorphine or procaine for pain relief. Both analgesics were administered as constant intravenous (i.v.) infusions and additional analgesics were given on demand. Pain scores were assessed on a visual analogue scale. Close clinical control and laboratory checks were performed during the three-day study period. RESULTS Patients receiving buprenorphine were significantly less likely to demand additional analgesics (1 versus 14 patients; P < 0.0001). The pain scores for patients in the buprenorphine group were significantly lower over the treatment period in comparison to procaine (P < 0.05). The reduction of pain score was significantly greater during the initial two treatment days using buprenorphine (day 1: 55 versus 25, P < 0.0001; day 2: 62 versus 40, P = 0.005). Side effects were comparable for both groups with the exception of a slightly higher sedation rate under buprenorphine. CONCLUSIONS Constant i.v. application of buprenorphine is more effective than the recommended procaine for pain relief in acute pancreatitis.

Abstract
We investigated in a large industrial population the antibody response to specific H. pylori antigens (CagA and seven others) in relation to peptic ulcer and nonulcer dyspepsia (NUD). The two groups consisted of 37 and 39 employees, respectively, with endoscopically proven peptic ulcer and NUD. Age- and gender-matched controls were H. pylori seropositive employees without abdominal complaints or history of ulcer disease. IgG antibodies against CagA and other antigens were analyzed by western immunoblot. Relative percentages of CagA-positive individuals were 89 and 76% for ulcer cases and their controls (P = 0.22) and 77% and 74% for NUD cases and their controls. The corresponding percentages of VacA-positive individuals were 87 and 76% for ulcer cases and controls and 64% and 77% for NUD cases and controls, respectively. Analysis of other H. pylori-specific antigens was not particularly helpful in discriminating between symptomatic and asymptomatic seropositive individuals for either disease group. In conclusion, assessment of IgG response against specific H. pylori antigens was not predictive of peptic ulcer or NUD case status in this active employee population and would not appear to be useful in routine clinical practice.
