Intraoperative ultrasonography (I.US) has been introduced in order to overcome the limits of the preoperative imaging modalities (notably, ultrasonography and computed tomography), both in pancreatic cancer diagnosis and staging. The authors' experience encompasses 32 cases, selected according to the following criteria: lesions that could not be detected both preoperatively and at surgical exploration; lesions detected but not properly characterized, requiring differential diagnosis between cancer and pancreatitis; tumoral lesions with a perspective of radical surgery, in which the preoperative judgment of resectability had to be verified. In the only case of the first group, I.US allowed the identification of a small cancer in a jaundiced patient. In the 11 cases of the second group, I.US-guided fine-needle aspiration biopsy showed three cancers; however, among the other 8 lesions classified as pancreatitis there was one false negative diagnosis (a tumoral mass with liver metastases was demonstrated by computed tomography 6 mo later). Regarding the intraoperative staging of the proven cancers (20 cases of the third group; 4 cases of the first and second groups), I.US changed the planned surgical approach in 9 cases (showing vascular involvement or detecting liver metastases and enlarged lymph nodes not seen preoperatively); in 12 cases it confirmed the possibility of radical surgery. Finally, in the remaining 3 cases, I.US provided dubious information: only vascular dissection during surgery could achieve a correct evaluation, ruling out vascular involvement and thus allowing tumor resection.

Over a 7-year period, 91 patients with tropical pancreatitis underwent operation for intractable pain. Univariate and multivariate analyses were performed to identify factors correlating with mortality, major complications, poor pain relief and associated malignancy. Patients with benign disease (group 1, n = 72) had longer survival than those with superimposed malignancy (group 2, n = 19). Pain relief was better in group 1 (59 patients compared with none, P less than 0.01). Age above 40 years, short duration of symptoms, mass lesions on ultrasonography and main pancreatic duct obstruction on endoscopic retrograde pancreatography were associated with a high risk of cancer. After reoperation major complications (four of ten) or death (three of ten) occurred more commonly than after primary procedures (seven of 81, P = 0.019 and five of 81, P less than 0.05, respectively). Poor pain relief in group 1 patients was more common after incomplete clearance of main duct stones (four of 13 versus three of 53, P less than 0.01) and after short length ductotomy (three of eight versus four of 58, P less than 0.01). Tropical pancreatitis has a high association with pancreatic adenocarcinoma. Wide ductotomy, stone clearance and drainage gave good symptomatic results in patients with benign disease. Overall results were poor in patients with cancer.

Intraoperative radiotherapy (IORT) is being used with increasing frequency in many institutions in the United States but little is known about the surgical complication rates. The Radiation Therapy Oncology Group initiated three prospective studies in IORT in 1986 and we report here the experience in advanced malignancies of the stomach, pancreas, and rectum. The incidence and nature of major surgical complications were reviewed and presented with their implications in regard to future IORT trials. Two hundred twenty-seven patients were entered on three studies by 20 participating institutions between 1985 and 1989. One hundred twenty-nine patients received IORT while 98 patients were found to have too advanced disease to be benefited by IORT and underwent palliative surgical procedures only. IORT doses ranged from 12-22 Gy and bowel anastomoses were not irradiated. Wound infection in the IORT group was 6% vs. 2% in the non-IORT patients but this was not significant at the P = 0.05 level. Other complications included anastomotic leak (n = 5), operative bleeding (n = 10), pancreatitis (n = 2), and were not statistically different in the IORT and non-IORT groups. The mortality rate for the IORT and non-IORT groups combined was 1.8%. This large multi-institutional experience in patients with advanced malignancy demonstrates that patients receiving IORT do not have a higher surgical complication rate than those not receiving IORT. Long-term survival data await the implementation of Phase III trials in advanced intra-abdominal malignancy.

Pancreatic adenocarcinoma occurred in 22 of 266 patients with tropical pancreatitis presenting over an 8-yr period (8.3%). We compared the data on three groups: group 1, patients with tropical pancreatitis (benign, n = 82); group 2, tropical pancreatitis with super-imposed malignancy (n = 22), and group 3, those with de novo cancer (n = 76). Factors associated with high risk for cancer in tropical pancreatitis were age greater than 40 yr, short symptom duration, weight loss, mass on ultrasound, and ductal block on endoscopic retrograde cholangiopancreatography. Tropical pancreatic cancers had distinct differences from de novo cancers: younger mean age (47 vs. 61 yr), calculi in all (vs. none in group 3), diabetes in 16 of 22 (73%) versus 18 of 76 (24%), and tumors in body and tail in 16 of 22 (73%) versus 26 of 76 patients (34%). In group 2, survival was poorer (10 vs. 17 months, p less than 0.01) than in group 3 (those with de novo cancer). Two of five resected specimens in group 2 showed features of dysplasia, in addition to cancer. Tropical pancreatitis has a high association with cancer. Malignancy occurring in tropical pancreatitis is distinct from de novo cancer. When considered in the light of the low incidence of pancreatic cancer in southern India, the above evidence suggests a possible etiological relationship.

Sixty-six consecutive patients with unresectable hepatocellular carcinoma (HCC) were treated with transcatheter arterial chemoembolization (TACE) using aclarubicin microspheres (ACRms) in combination with cisplatin suspended in iodized oil (Lipiodol, Laboratoire Guerbert, Paris, France) (CSL). The stages of the disease were as follows: Stage I (n = 1), Stage II (n = 10), Stage III (n = 26), and Stage IV (n = 29). The effectiveness of TACE was assessed by comparing ACRms with CSL with ACRms without CSL. Of 66 patients treated with ACRms and CSL, 62 (93.9%) could be examined for response. According to response criteria, there were 31 (50.0%) partial responses and 17 (27.4%) minor responses. In 13 cases (21.0%) there was no change and in 1 case (1.6%) there was progressive disease. The cumulative survival rate was 80.7% at 1 year, 64.2% at 2 years, and 50.6% at 3 years. The rates were significantly higher than those of the group treated with ACRms. Eleven patients in the ACRms and CSL group experienced clinical complications: cholecystitis (4.5%), pancreatitis (3.0%), liver abscess (3.0%), hepatic failure (3.0%), gastrointestinal bleeding (1.5%), and renal failure (1.5%). No lethal side effects related to the therapy were observed. TACE using ACRms in combination with CSL prolongs the survival of patients with unresectable HCC.

The clinical, biochemical and radiological data of 25 patients with carcinoma of the head of the pancreas were compared with the same parameters of 25 patients with chronic pancreatitis producing cholestasis. History of alcohol abuse, pruritus and palpable gallbladder were the only clinical findings useful for the differential diagnosis. Plasma bilirubin levels were significantly higher in patients with malignancy (20.0 +/- 14.3 vs 2.5 +/- 2.4) but the course of the bilirubinemia was similar in the two groups after hospital admission. Preoperative ultrasound and cholangiography were usefull in differentiating both groups of patients. Sensibility of a point score based on significant differences was 100% for pancreatitis and 96% for malignancy.

Laparoscopic cholecystectomy (LC) has rapidly gained wide acceptance in the United States. The applicability, safety and efficacy of this new procedure for the treatment of cholelithiasis in Taiwan, however, needs evaluation. We performed LC in 50 out of 98 cases of cholelithiasis at Cathay General Hospital from 28 December 1990 to 28 April 1991. We found that the applicability rate was 51%. The reasons for not selecting LC in the 48 open cases were: acute and gangrenous cholecystitis (13), common bile duct stones (11), concomitant intra-abdominal malignancy (5), intrahepatic stones (5), multiple upper abdominal incisions (4), pancreatitis or pancreatic abscesses (3) and other causes (7). In the LC group, there were 44 patients with symptomatic chronic calculus cholecystitis, 3 patients with acute calculus cholecystitis and 3 patients with gall bladder polyps. The age of the patients ranged from 27 to 79. There were 14 males and 36 females. All of the patients had a detailed preoperative workup including complete liver function test and sonographic examination of the hepatobiliary system. Additional pre-operative endoscopic retrograde cholangiopancreatographies were done in 3 and operative cholangiograms were done in another 3 to confirm the absence of common bile duct stones or to delineate anatomy. Although we encountered a few problems during the operations, such as severe adhesion, bleeding, difficult dissection, CO2 leakage, difficult insufflation, or large stones, all of the 50 patients completed the LC successfully without conversion to open cholecystectomy. The average operation time was 60 minutes, ranging from 30 to 135 minutes. Drain tubes were used in 7 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

Celiac plexus block is usually performed under fluoroscopic or tomodensitometric guidance. We report on a new procedure using sonographic guidance. the patient lies in supine position. We use a real-time sonograph with a 3.5 MHz probe. On a transverse plane, the celiac axis is localized emerging from the aorta. Under local anesthesia, the tip of the spinal needle (177 mm, 22 g) is placed close to the aorta (about 5 mm) on both sides. 5 to 10 ml of 1% lidocaine, then 10 to 20 ml of absolute alcohol, are injected on each side. 21 patients (10 males, 11 females, mean age: 61.4) underwent the procedure. They presented with cancer of the pancreas in 14 cases, metastatic nodes from an extra-pancreatic tumor in 5 cases and chronic calcifying pancreatitis (CCP) in 2 cases. No pain relief was secured in 3 patients (14%). One of these presented with CCP, but endoscopic cystic diversion of a small cyst was successful in eradicating pain. Partial pain relief was secured in 5 cases (24%) and total pain relief in 13 cases (62%). No treatment-related complication was observed. We conclude that sonography is a simple and safe method of guidance in performing alcohol block of the celiac plexus. The anterior approach may prevent neurologic complications occurring with other methods of guidance using a posterior approach.

Diagnostic significance of serum immunoreactive elastase 1 (IRE) in pancreatic cancer was evaluated in 53 patients with pancreatic cancer. Frequency of abnormally high serum IRE levels in pancreatic cancer was 66.0%; 87.0% in head cancer (N = 23), 55.0% in body & tail cancer (N = 20) and 40% in diffuse cancer (N = 10). Serum IRE level in resectable cancer was significantly higher than that in unresectable cancer. Comparative studies of serum pancreatic enzymes revealed that serum IRE was the most sensitive marker for diagnosis of pancreatic cancer. The characteristic behavior of serum IRE throughout the course of pancreatic cancer was that abnormally high levels of IRE are maintained for a longer period of time when compared to that of pancreatitis. In the comparative study of serum IRE and CA19-9, of the 9 cases of pancreatic cancer with CA19-9 levels less than 100U/ml, 7 showed abnormally high values of IRE, and of these 4 were resectable. These results indicate that in order to detect early pancreatic cancer, any elevation of serum IRE before CA19-9 increase should be noted with care, and patients who particularly show elevated IRE values for more than one month should be subjected to more extensive morphological examinations.

We reviewed the results of 187 consecutive ultrasound-guided fine-needle biopsies of the pancreas in 171 patients to assess the diagnostic accuracy of the method. The final diagnosis obtained at operation, autopsy or follow-up were: adenocarcinoma (n = 83), metastatic cancer (n = 11), cystadenocarcinoma (n = 2), lymphoma (n = 2), malignant gastrinoma (n = 1), pseudocyst (n = 25), cyst (n = 13), chronic pancreatitis (n = 9), normal pancreas (n = 10), abscess (n = 7), benign islet-cell tumour (n = 5), cystadenoma (n = 3). Sufficient cytologic material was obtained in 95.3% of biopsies and the overall accuracy in distinguishing benign from malignant disease was 85.4%. False negative results were obtained in 12 patients (13.1%). Inconclusive results (CIII) were found in aspirates from one cyst and two islet cell tumours. There were no false-positive results. The only complication was a post-biopsy haematoma around the head of pancreas, which resolved spontaneously. Ultrasound-guided pancreatic fine-needle biopsy is a safe method and allows of a high degree of diagnostic accuracy. It has a high specificity. Its sensitivity in the detection of malignancy improves if biopsies are repeated in doubtful cases. It further permits tumours to be graded and allows complications of pancreatitis to be diagnosed.
