E.J. Clark; Saxon Connor; M.A. Taylor; K.K. Madhavan; O.J. Garden; Rowan W. Parks

BACKGROUND AND AIMS Recognized prognostic factors for resected pancreatic ductal adenocarcinoma (PDAC) include tumour size, differentiation, resection margin involvement and lymph node metastases. A further prognostic factor of less certain significance is lymphocyte count. The aim of this study was to investigate whether preoperative lymphocyte count is a prognostic indicator in patients with PDAC. MATERIAL AND METHODS Patients who had undergone a potentially curative pancreaticoduodenectomy (PD) for PDAC between 1998 and 2005 were analysed. Standard prognostic factors, preoperative lymphocyte count, preoperative neutrophil count and survival data were collected. RESULTS Of the 44 patients studied, univariate analysis identified predictors of a poor survival as lymph node status (node positive (+ve) 10.3 [5.4-20.9] months versus node negative (-ve) 14.2 [10.9-31.4] months; p=0.038), posterior resection margin invasion (margin +ve 7.0 [5.1-15.0] months versus margin -ve 13.1 [10.0-28.3] months; p=0.025) and lymphocyte count below the reference range (<1.5 x 10(9)/litre 8.8 [7.0-13.1] months versus > or = 1.5 x 10(9)/litre 14.3 [7.0-28.3] months; p=0.029). Low preoperative lymphocyte count (p=0.027) and posterior margin invasion (p=0.023) retained significance on multivariate analysis. Preoperative neutrophil to lymphocyte ratio was not a significant prognostic factor. CONCLUSION Preoperative lymphocyte count is a significant prognostic factor in patients with PDAC.

BACKGROUND Despite refinements in the management of choledochal cysts in children, an increasing number of patients present with ongoing symptoms in adult life. The aim of this study was to review the management of adult patients with choledochal cysts in a tertiary referral centre. METHOD A retrospective review was carried out of all adult patients presenting with choledochal cysts to this department between 1992 and 2000. Patient records were reviewed and detailed analyses were made of the clinical presentation, radiological and biochemical findings, anatomical anomalies, management, complications and outcomes. RESULTS Of 16 patients (12 women and 4 men; median age 23 years), 8 had undergone previous upper gastrointestinal operations before referral, including 5 who had had previous cyst drainage procedures. All patients underwent elective complete cyst excision with Roux-en-Y hepaticojejunostomy. There were no operative deaths and there was a low early postoperative morbidity rate (25%). There was no evidence of biliary malignancy in any cyst. During a median postoperative follow-up of 44 months, five patients (31%) continued to experience cholangitis and two of these required additional revisional procedures, but are now symptom-free. CONCLUSION Patients with choledochal cysts should be referred to specialised tertiary surgical units. Total choledochal cyst excision with Roux-en-Y hepaticojejunostomy is the treatment of choice. Patients with previous inadequate cyst excisional procedures should undergo revisional surgery, to reduce recurrent symptoms and the risk of developing cholangiocarcinoma.

BACKGROUND Hepatic resection is indicated for a variety of benign conditions because of persistent symptoms, uncertainty regarding the diagnosis or the risk of malignant transformation. The aim of this study was to assess the indications for and outcome of hepatic resection for benign non-cystic liver lesions in a specialist hepatobiliary unit. PATIENTS AND METHODS All patients who had undergone hepatic resection for benign non-cystic hepatic lesions between 1989 and 2001 were identified from a prospective database for analysis. RESULTS A total of 49 patients (40 women, 9 men) with a mean age of 43 years (range 21-75 years) underwent resection of non-cystic benign lesions. Indications for operation included suspected liver cell adenoma (n=11), suspicion of malignancy (11), persistent symptoms attributable to the lesion (20) or chronic sepsis (7). The final diagnosis was focal nodular hyperplasia (n=12), haemangioma (12), adenoma (8), sclerosing cholangitis (5), inflammatory pseudotumour (4), intrahepatic cholelithiasis (3), chronic hepatic abscess (3), benign biliary fibrosis (I) and leiomyoma (I). Major anatomical hepatic resections were performed in 44 patients, and 5 patients underwent a segmentectomy or minor atypical resection. Median operating time was 215 min (range 45-450 min) and median blood loss was 875 ml (range 200-4000 ml). Ten patients (20%) required a median blood transfusion of 2 units (range 2-8 units). The median postoperative stay was 10 days (range 4-33 days). There were no deaths, but complications occurred in 15 patients (27%). CONCLUSIONS Hepatic resection can be safely recommended for selected patients with a variety of benign non-cystic hepatic lesions. A small group of patients undergo resection as a result of inability to rule out a malignant process, but the large majority will be operated on because of either their malignant potential or related symptoms.

A 10‐year experience in the management of gallbladder cancer

G.C.S. Smith; Rowan W. Parks; K.K. Madhavan; O.J. Garden

BACKGROUND The aim of this retrospective study was to review all patients diagnosed with gallbladder cancer over a 10-year period to assess variables affecting survival. METHODS Patients diagnosed with gallbladder cancer from January 1990 to December 1999 were identified from the Lothian Surgical Audit database and a case-note review was performed. RESULTS The 44 patients who were studied (33 women, 11 men) had a mean age of 66 years (range 42-90 years). The diagnosis was established preoperatively in 25 patients (57%), intraoperatively in 5 patients (11%) and incidentally following pathological examination of cholecystectomy specimens in 14 patients (32%). None of the 25 patients diagnosed preoperatively underwent curative operations (median survival 4 months). All five patients diagnosed at the time of attempted cholecystectomy had advanced irresectable disease (median survival 1 month). The overall median survival in 14 patients with an incidental diagnosis of gallbladder cancer was 16 months; however, in eight of these patients who were considered to have had a potentially curative resection, the median survival was 38 months. DISCUSSION The prognosis for patients diagnosed preoperatively or at the time of cholecystectomy is very poor. Patients with an incidental finding of gallbladder cancer have a significantly better prognosis and should be considered for further radical re-resection.

BACKGROUND AND AIMS Pancreaticoduodenectomy (PD) is a major operative intervention performed most commonly for malignancy in the head of pancreas. The aim of this study was to evaluate the utilization of blood transfusion for PD and to determine whether this had prognostic significance in a subset of patients with pancreatic ductal adenocarcinoma (PDAC). MATERIAL AND METHODS Data on blood transfusion requirement were retrospectively collected for patients undergoing PD from 1998 to 2005. Standard prognostic factors and survival data were also collected in patients with PDAC. RESULTS One-hundred-and-seventy patients underwent PD. Seventy-six patients (45%) received transfusion. The median (interquartile range) number of units of red cell concentrate (RCC) transfused perioperatively (intraoperatively and within 24 h of surgery) was 1.5 (0.5-2.5). The median preoperative haemoglobin (Hb) was 126 g/dl. The median number of units of RCC transfused perioperatively in patients with Hb <126 g/dl was 2 (1-3); for those with Hb > or = 126 g/dl the median was 0 (0-1); p=0.003. Forty-nine patients who were resected for PDAC were subjected to survival analysis. Univariate and multivariate analyses showed that only posterior resection margin invasion was associated with an adverse outcome (margin positive 198 [143-470] days vs margin negative 398 [303-859] days; p=0.02). Perioperative RCC transfusion requirement was not a significant predictor of survival (transfusion 408 [214-769] days vs no transfusion 331 [217-391] days; p=0.18). Furthermore, RCC transfusion within 30 days of operation was not a significant predictor of poor survival (transfusion 331 [201-459] days vs no transfusion 317 [196-769] days; p=0.43). CONCLUSIONS PD can be performed with a moderately low requirement for RCC transfusion; however, low preoperative haemoglobin is a predictor for the requirement of RCC transfusion. Administration of RCC transfusion does not appear to be a significant adverse prognostic factor in patients with resected PDAC.

Results of decompression surgery for pain in chronic pancreatitis

J.D. Terrace; H.M. Paterson; O.J. Garden; Rowan W. Parks; K.K. Madhavan

INTRODUCTION A vast majority of patients with chronic pancreatitis require regular opiate/opioid analgesia and recurrent hospital admission for pain. However, the role and timing of operative strategies for pain in chronic pancreatitis is controversial. This study hypothesized that pancreatic decompression surgery reduces analgesia requirement and hospital readmission for pain in selected patients. PATIENTS AND METHODS This was a retrospective review of patients undergoing longitudinal pancreatico-jejunostomy (LPJ), with or without coring of the pancreatic head (Freys procedure), between 1995 and 2007 in a single UK centre. Surgery was performed for chronic pain with clinical/radiological evidence of chronic pancreatitis amenable to decompression/head coring. RESULTS Fifty patients were identified. Thirty-six were male with a median age of 46 years and median follow-up of 30 months. Twenty-eight underwent LPJ and 22 underwent Freys procedure. No significant difference in reduction of analgesia requirement (71% vs 64%, p=0.761) or hospital readmission for pain (21% vs 23%, p=1.000) was observed when comparing LPJ and Freys procedure. Patients were significantly more likely to be pain-free following surgery if they required non-opiate rather than opiate analgesia preoperatively (75% vs 19%, p=0.0002). Fewer patients required subsequent hospital readmission for pain if taking non-opiate rather than opiate analgesia preoperatively (12.5% vs 31%, p=0.175). CONCLUSIONS In selected patients, LPJ and Freys procedure have equivalent benefit in short-term pain reduction. Patients should be selected for surgery before the commencement of opiate analgesia.
