Operative treatment of pseudocysts in patients with chronic pancreatitis.

BACKGROUND: Pseudocysts associated with chronic pancreatitis are generally intrapancreatic and associated with parenchymal disease. They tend to persist and cause complications. Minimally invasive methods of treatment challenge the traditional techniques of operative management. Surgical operation allows definitive treatment of the pseudocyst with the option of dealing appropriately with the diseased pancreas and excluding a neoplastic process. The aim of this study was to review the safety and efficacy of a surgical approach to the management of pseudocysts associated with chronic pancreatitis. METHODS: A personal series of 112 consecutive patients operated for pseudocysts in the setting of chronic pancreatitis was reviewed. Chronic pancreatitis was confirmed by imaging studies in association with exocrine and/or endocrine failure. Cysts were multiple in 31 patients and presented with complications other than pain in 47. Data were collected prospectively regarding the clinical presentation, the nature of the operation and its outcome. RESULTS: Forty-eight patients (43 per cent) underwent drainage procedures, 56 (50 per cent) had a resection and eight (7 per cent) had a combination. Larger cysts and those located in the head and neck tended to be drained, while smaller and distal cysts were more often resected. The morbidity rate was 28 per cent and the operative mortality rate was 1 per cent. The cyst recurrence rate was 3 per cent and pain was relieved in 74 per cent of patients. CONCLUSION: Operative management of pseudocysts associated with chronic pancreatitis is effective with low morbidity and mortality rates. The introduction of newer minimally invasive techniques will have to withstand comparison to this traditional approach.

Early experience in the use of Levovist ultrasound contrast in the evaluation of liver masses.

The aim of the present paper was to assess the utility of Levovist in defining the pathology of liver masses. Levovist is a new ultrasound contrast agent consisting of galactose microparticles, air bubbles and palmitic acid. Prospective studies were performed in patients referred for further evaluation of known liver masses. Levovist was peripherally injected and colour Doppler ultrasound studies were performed. Findings were correlated with clinicopathology and three other imaging modalities: biphasic spiral CT, CT arterial portography and contrast MRI. Twenty-five patients were studied (15 male and 10 female) in the age range 25-74 years. Liver masses ranged from 0.5 to 7 cm in maximum diameter. Thirteen lesions were benign and 12 were malignant (four hepatomas (HCC) and eight metastases). Levovist enhancement occurred in 18 lesions. Of these, six were benign (four focal nodular hyperplasias (FNH) and two haemangiomas). All 12 malignant lesions demonstrated enhancement. The HCC showed a mosaic pattern of central and peripheral enhancement, and the FNH demonstrated a spoke-wheel pattern. It was not possible to distinguish between haemangiomas and malignant lesions. Non-enhancing lesions may well be benign, with all malignancies showing some enhancement. Characteristic enhancement patterns were found for HCC (mosaic) and FNH (spoke-wheel). It was not possible to distinguish between metastases and benign lesions (haemangiomas) when the pattern of enhancement was peripheral.

Case report: inappropriate use of percutaneous drainage in the management of pancreatic necrosis.

We describe three cases of severe necrotizing pancreatitis, with Apache II scores of 11, 17 and 22, respectively. There was no significant pancreatic parenchymal perfusion in any of the three patients on contrast-enhanced computed tomography. All three patients were primarily treated with percutaneous drains and all three subsequently required open laparotomies. We do not recommend percutaneous drainage as a definitive therapy for severe necrotizing pancreatitis.

Is radical hepatic surgery safe?

BACKGROUND: A prospective review of 200 consecutive liver resections performed for benign and malignant disease, between 1989 and 1995 at the Hammersmith Hospital, was undertaken to evaluate the safety of radical hepatic resection. METHODS: The indications for operation were: hepatocellular carcinoma (n = 39), cholangiocarcinoma (n = 21), gall bladder carcinoma (n = 8), colorectal secondaries (n = 75), noncolorectal secondaries (n = 35), and benign disease (n = 26). Twenty patients were cirrhotic and 36 were jaundiced. Major resections were performed in 74% of cases and included 63 extended hepatectomies, 17 repeated resections for recurrent colorectal metastases, and 17 resections combined with vascular reconstruction. Total vascular exclusion of the liver was used in the majority of cases. RESULTS: The overall mortality rate was 5%. Thirty-day mortality was 2.5%. Sepsis and not hemorrhage was the most common cause of death. There were 101 complications that occurred in 37% of the patients. The main complications were subphrenic abscess and biliary leak. The extent of liver resection (major versus minor) significantly increased the risk of morbidity (46% versus 16%). Blood loss greater than 100 mL increased the risk of morbidity from 12% to 25%. CONCLUSIONS: Major hepatic resection can be achieved with acceptable mortality but high morbidity rates.

Complications of laparoscopic fundoplication: the first 100 patients.

Laparoscopic fundoplication is being performed with increasing frequency. The learning curve for the operation is long, and we herein discuss some of the problems we have experienced with this surgery. We also discuss changes we have made in our technique as the result of our experiences.

Injuries to the bile duct resulting from laparoscopic cholecystectomy.

Laparoscopic cholecystectomy has now become the treatment of choice for symptomatic gall stones. There does, however, appear to be an increased incidence of bile duct injuries. In this article, experience with eight patients who sustained a bile duct injury and were referred to the Hepatobiliary Service at Westmead Hospital, between 1990 and 1992, is reported.

Bleeding duodenal ulceration: the results of emergency treatment with highly selective vagotomy.

We report the results of a prospective study of all patients undergoing highly selective vagotomy (HSV) for bleeding duodenal ulceration (BDU) at Concord Hospital between 1979 and 1989. Highly selective vagotomy was undertaken in 63 patients (58 male, 5 female) with a median age of 69 years (range: 16-89). Fifty-five patients were reviewed, 7 patients having died in the peri-operative period and one being lost to follow-up. The mean period to review was 50 months (range: 1-120). Thirty-six patients have been followed-up for more than 24 months. Thirty-day postoperative mortality was 11% (7 patients). Combined major and minor morbidity was 41%. Postoperative rebleeding occurred in four patients (6.3%), three of whom died. Ulceration had recurred in two of 55 patients (4%). Symptoms have been evaluated in 55 patients since operation and 93% have been graded as Visick I or II. We conclude that HSV is effective in the emergency treatment of BDU and has few long-term sequelae.
