It is not easy to weigh up therapeutic and toxic effects in the medical treatment of intestinal cancer. The number of drugs that have demonstrated certain activity in these forms is extremely limited, only 5 FU being definitely active and even this only in a small percentage of patients. 5 FU produces remission in some 20% of cases. It is highly probable that prophylactic treatment with 5 FU increases patient survival as reported by Regelson and other workers, but the resulting damage (hepatic, bone marrow, immunodepression, etc.) must also be assessed and the risk of a second neoplasia should not be forgotten. The personally used association of 5 FU and cyclophosphamide has proved active at least to the same extent as 5 FU alone, while toxic effects were not particularly important. Brilliant but unfortunately temporary results can be obtained by peritoneal PTC in peritoneal carcinomatosis. Good results with respect to the pain symptom have been obtained by associating 5 FU with radiotherapy in non-operable intestinal tumours.

The value of endoscopic retrograde cholangiopancreaticography (ERCP) for establishing the indication for surgery and for planning surgical procedures is discussed. The two most widely practiced methods of direct cholangiography - percutaneous transhepatic and endoscopic retrograde cholangiography (PTC and ERC) - are compared: although the filling rate with ERC is slightly lower than with PTC, the endoscopic method has some important advantages as it allows endoscopic observation and biopsy of the duodenum. Furthermore, opacification of the pancreatic duct system often provides important additional information. ERCP is essentially important in post-cholecystectomy syndrome, as puncture of undilated bile ducts is difficult and persistent symptoms after cholecystectomy are not infrequently related to pancreatic disease. The importance of rapid surgical intervention after retrograde filling of the biliary tree in obstructive jaundice is stressed. In pancreatic diseases the indication for surgery is based mainly on clinical and laboratory findings. Differentiation of malignant and inflammatory changes in the pancreaticogram is still a problem. However, the contribution of ERCP to pancreatic surgery is very important, as it exactly localized lesions of the pancreas and therefore allows detailed planning of a surgical procedure. Stenosing or obstructing lesions often are an indication for surgery, even if their malignant nature is not certain, as severe pain in chronic pancreatitis may be relieved by surgery. The potential for therapeutic application of endoscopy in biliary and pancreatic diseases is briefly discussed.

A total series of 68 unselected patients with gallbladder cancer, diagnosed during 1972 to 1981, was studied retrospectively. In 61 cases (90%), the diagnosis was histologically verified. The cardinal symptoms were local pain (87%), loss of weight (53%), and jaundice (59%). The diagnosis was established after autopsy in 22 patients (32%), and exploratory laparotomy in 22 patients (32%). Palliative surgery was carried out in 26 patients of whom seven (27%) died postoperatively. Only one patient, with an incidentally detected cancer at routine cholecystectomy, was treated radically. Four out of nine patients died within one month after PTC-drainage. The mean survival time for the whole series was 2.9 months. The longest survival was 21 months. Considering the increasing incidence of gallbladder cancer in Sweden, as well as of other cancers of the biliary system, these findings emphasize the need for intensified research. An epidemiological approach studying the correlation of gallbladder cancer with the changing trend of gallstone disease and its treatment would perhaps be fruitful.

In 16 patients percutaneous transhepatic cholangiography with a conventional needle was attempted, to establish the diagnosis of obstructive jaundice and show the nature and site of obstruction. The procedure was successful in 15 patients; only one patient subsequently had parenchymal jaundice. The conventional needle allowed bile aspiration (a mean of 22 mls in the 15 patients), which may have been an important factor in avoiding the development of post PTC septicemia. No patient had pain, bile leakage, bleeding or septicemia following the procedure. Surgery was performed as scheduled. Following the use of the conventional sheathed needle, it does not appear necessary to operate immediately.

PTC was performed in 86 patients with obstructive jaundice, between February/80--March/81 diagnosing 20 cases of the hepatic hilium carcinoma, 14 of pancreatic carcinoma, and 2 multiplex abscess of the liver. PTC-D was successfully attempted on 16 patients, catheterizing the intrahepatic biliary tree in 15 and maintaining a good biliary flow in 10 of them. The catheter was on the correct position into the biliary tree in 6 patients, and the drainage continued for 7-20 days. General improvement was obtained in 83.33%, itching decreased in 40% and disappeared in 60%, cholestasis was reduced in 100% and sepsis in 75%. Complications of the technique were: pain during the introduction of the guide wire (18.75%) and transitory hemobilia (31.21%). PTC-D seems to be a procedure with a precisely indication in every transitory obstructive jaundice, in order to put the patient in better conditions to a definitive therapy: 1) Surgery 2) Prosthesis 3) External-internal biliary drainage.

The authors report a case of massive hematobilia due to hemorrhagic cholecystitis. Hematobilia is a rare pathology which affects the biliary tract and gallbladder. The first authors to describe hematobilia defined it as a hemorrhage of the gastroenteric tract due to the communication of blood vessels with the intra and extra-hepatic biliary tract and in some rare cases to the communication of the branches of the cystic artery within the gallbladder wall. Sandblom, in particular, specified that bleeding must be within the biliary tract and not secondary to an enterobiliary fistula. In 55% of cases the pathogenesis of hematobilia is traumatic, whereas in the remaining 45% the cause may be attributed to a variety of pathologies. Trauma include both non-surgical and surgical traumas; in the first group the most frequent cause is hepatic trauma, although it is worth taking into account the presence of post-traumatic arteriobiliary fistulas, lesions of arterial vessel walls with subsequent necrosis and rupture within the biliary vessels. Surgical traumas comprise lesions caused by therapeutic or diagnostic transparenchymal manoeuvres (PTC, biopsy). Non-traumatic causes include pathologies of vascular, cholecystic, inflammatory-infective and neoplastic origin. Symptoms are varied and take the form of anemia, massive bleeding with the onset of jaundice and pain in the hypochondrium and sometimes the epigastrium, whereas enterorrhagia is manifested by melena and more rarely hematemesis. The diagnosis must be made as quickly as possible; mortality increases with the delay in controlling hemorrhage. Differential diagnosis must take into account other causes of enterorrhagia, obstructive jaundice and anemia.(ABSTRACT TRUNCATED AT 250 WORDS)

The visual analogue scale (VAS) is an established, validated, self-report measure usually consisting of a 10 cm line on paper with verbal anchors labeling the ends. Palmtop computers (PTCs also known as personal digital appliances) have incorporated VAS entry by use of a touch screen. However, the validity and psychophysical properties of the electronic VAS have never been formally compared with the conventional paper VAS. The aim of this study is to determine the agreement between the electronic (eVAS) and paper (pVAS) modes. Twenty-four healthy volunteers were recruited for this study. Each study participant provided input using both measurement methods by marking the eVAS and pVAS in response to two kinds of stimuli, cognitive and sensory. A verbal rating scale of seven descriptors of intensity represented the cognitive stimuli. Participants were asked to mark the location that best corresponded to the pain intensity described by each word on scales from 'no pain' to 'worst possible pain'. The sensory stimuli used were a set of test weights consisting of plastic containers ranging from 7 to 129 g. The VAS for sensory stimuli ranged from 0 (no weight) to 'reference weight' (the heaviest weight outside the range of test weights). There were two types of input stimuli and two modes for recording responses for a total of four experimental conditions. Two evaluators independently measured and recorded all the pVAS forms to the nearest millimeter. A total of 2016 stimuli were rated. The overall correlation for ratings of both sensory and cognitive stimuli on eVAS and pVAS was r = 0.91. For paired verbal stimuli the correlation was r = 0.97. For paired sensory stimuli the correlation was r = 0.86. The correlation between group eVAS and pVAS ratings to common verbal stimuli was r = 0.99. For common sensory stimuli the group correlation was r = 0.99. The median of correlations comparing eVAS and pVAS ratings was 0.99 for verbal stimuli and 0.98 for sensory stimuli. Multivariate analyses showed equivalent stimuli to be rated much the same whether entered on paper VAS or PTC touch screen VAS (P < 0.0001). Support was found for the validity of the computer version of the VAS scale.

Endoscopic retrograde cholangiopancreaticography is the standard therapy for the therapy of biliary obstruction. However, the success rate is not 100%, depending on various patient and physician related factors. In these cases, where endoscopic drainage is not possible, either percutaneous drainage or surgery are established alternatives. Both modalities carry a higher complication rate and are more invasive than endoscopic drainage. With linear echo-endoscopes, left intrahepatic bile ducts as well as the distal common bile duct can be visualized from the stomach or the duodenal bulb respectively. This opens up the possibility of puncturing the bile ducts under real time ultrasound control from the intestinal lumen. There are two different techniques to achieve biliary drainage after gaining EUS guided access: The first is direct biliary drainage in the intestinal lumen by placing a stent through the wall of the stomach/duodenum after placement of a guidewire through an 19gauge needle into the biliary tract. This technique usually requires some form of bouginage once the guide wire has been placed and is very similar to EUS guided pseudocyst drainage. The second technique is the rendezvous technique, where the guidewire is manipulated through the stricture and the papilla. Thereafter the wire is captured with a standard duodenoscope and a biliary drainage is performed through the papilla in established fashion. With both techniques fluoroscopic control in addition to EUS is needed. So far both techniques have been described in case reports and small series only. Large prospective series as well as controlled trials that compare EUS guided techniques with ERCP or PTC are lacking. The most common complication is biliary leakage, especially if direct drainage is performed. Other common complications include cholangitis, stent migration and occlusion as well as pain. As long as large prospective series are lacking, EUS guided biliary drainage should be restricted to selected patients where ERCP has repeatedly failed or is impossible due to surgically altered anatomy. Furthermore this technically demanding procedure should be performed only in centres with extensive experience in linear EUS and therapeutic biliary ERCP. The possible advantages over percutaneous drainage like patient comfort and morbidity have to be proven in randomized trials.

In this study, we investigated the therapeutic effects of treatment with (R)-Se-phenyl thiazolidine-4-carboselenoate (Se-PTC), an organic selenium compound with antinociceptive properties, against mechanical and thermal hyperalgesia induced by brachial plexus avulsion (BPA), a neuropathic model in mice. The involvement of cannabinoid CB(1) and CB(2) receptors in the Se-PTC anti-hyperalgesic effect was also investigated. Se-PTC treatment at (25 and 50mg/kg, per oral, p.o.) lowered (BPA model) induced mechanical and thermal hyperalgesia in mice. Pretreatment with cannabinoid CB(1) (AM251; 1mg/kg, intraperitoneally, i.p.), or CB(2) (AM630; 3mg/kg, i.p.) receptor antagonists reverted the mechanical and thermal anti-hyperalgesic effect of Se-PTC (25mg/kg) in the BPA model. Selective CB(1) (ACEA, 10mg/kg, i.p.) and CB(2) (JWH-133, 10mg/kg, i.p.) receptor agonists lowered mechanical and thermal hyperalgesia in the BPA model, and this effect was prevented by selective CB(1) and CB(2) receptor antagonists. Gabapentin (70mg/kg, p.o.), positive control administration also lowered mechanical and thermal hyperalgesia in the BPA model. The results suggest that the mechanical and thermal hyperalgesia observed following BPA in mice is dependent on cannabinoid receptors. The results indicate that modulating cannabinoid receptors represent a valuable approach for the treatment of neuropathic pain. In conclusion, the results suggested that Se-PTC produces pronounced mechanical and thermal anti-hyperalgesic effects in neuropathic models in mice by modulating CB(1) and CB(2) receptors.

Women who are carriers for hemophilia are usually considered as safe carriers. However, they can present hemorragic symptoms associated with low factor VIII or IX levels. During pregancy, factor VIII increases whereas factor IX does not. The peripartum period is at risk of increased bleeding in these women. Here are presented reports of clinical data concerning two hemophilia carriers with low factor VIII or IX (30-40%) during the peripartum period. They received remifentanil and ketamine for labor pain management because of contraindication of epidural and spinal analgesia. Delivery occured quickly but they presented immediate moderate postpartum haemorrage. They did not necessitate blood transfusion. The one with hemophilia A received desmopressin just after delivery and the other one received factor IX when she arrived in delivery room. Blood factor VIII or IX has to be assessed in these women with familial history of hemophilia and bleeding. During pregnancy, factor VIII increases and can be assessed many times during pregnancy expecting a level over 50%. Factor IX does not really increase during pregancy and hemorrage can occur. Epidural and spinal anesthesia seem to be contraindicated as far as recommandations are concerned. Coagulation factor substitution is a mean of increasing factor level before these anaesthesias and can be discussed for each case.
