Major resection for chronic pancreatitis in patients with vascular involvement is associated with increased postoperative mortality.

BACKGROUND: The aim was to evaluate the outcome of major resection for chronic pancreatitis in patients with and without vascular involvement. METHODS: Of 250 patients with severe chronic pancreatitis referred between 1996 and 2003, 112 underwent pancreatic resection. The outcome of 17 patients (15.2 per cent) who had major vascular involvement was compared with that of patients without vascular involvement. RESULTS: The 95 patients without vascular involvement had resections comprising Beger's operation (39 patients), Kausch-Whipple pancreatoduodenectomy (28), total pancreatectomy (25) and left pancreatectomy (three). Twenty-five major vessels were involved in the remaining 17 patients. One or more major veins were occluded and/or compressed producing generalized or segmental portal hypertension, and three patients also had major arterial involvement. Surgery in these patients comprised Beger's operation (eight), total pancreatectomy (five), Kausch-Whipple pancreatoduodenectomy (two) and left pancreatectomy (two). Perioperative mortality rates were significantly different between the groups (two of 95 versus three of 17 respectively; P = 0.024). There were similar and significant improvements in long-term outcomes in both groups. CONCLUSION: Resection for severe chronic pancreatitis in patients with vascular complications is hazardous and is associated with an increased mortality rate. Vascular assessment should be included in the routine follow-up of patients with chronic pancreatitis, to enable early identification of those likely to develop vascular involvement and prompt surgical intervention.

Survival of patients with periampullary carcinoma is predicted by lymph node 8a but not by lymph node 16b1 status.

BACKGROUND: The aim of this study was to assess the impact of metastatic disease in lymph nodes 8a and 16b1 (as defined by the Japanese Pancreas Society) on survival in patients with periampullary malignancy. METHODS: Patients undergoing resection for primary pancreatic ductal adenocarcinoma or intrapancreatic bile duct adenocarcinoma were identified from a prospective database (September 1997-May 2003). RESULTS: Thirteen of 54 and ten of 44 evaluable patients had metastatic involvement of lymph nodes 8a and 16b1 respectively. Metastatic involvement of lymph node 8a was associated with a significantly shorter median survival (197 versus 470 days; P = 0.003) but metastatic involvement of lymph node 16b1 did not affect survival (457 versus 503 days; P = 0.185). Multivariate analysis showed lymph node 8a status to be the strongest predictor of outcome (P = 0.006). Median survival of those with metastatic lymph node 8a was not significantly different from that of 81 patients with overt metastatic periampullary cancer at the time of diagnosis (98 days; P = 0.072) CONCLUSION: Lymph node 8a was an independent prognostic factor in patients with periampullary malignancy, but lymph node 16b1 was not. Survival in those with metastatic lymph node 8a was not significantly different from that in patients with metastatic disease at presentation. Preoperative determination of lymph node 8a status may have important implications in selecting patients for treatment.

Influence of opioid use on surgical and long-term outcome after resection for chronic pancreatitis.

BACKGROUND: The outcome of pancreatic resection for chronic pancreatitis in patients with preoperative opioid use is not well described. METHODS: During 1997 to 2003, 112 of 231 patients referred with chronic pancreatitis underwent pancreatic resection. The outcome of patients who had preoperative opioid use (N=46) was compared with those without (N=66). RESULTS: Patients who used opioids presented at a younger age and had a younger age of symptom onset, longer symptom duration, more hospitalizations, a higher frequency of diabetes mellitus, a higher pain score, and more restriction in daily activity (all P<.05). Twenty-one (46%) patients with opioid use had a total pancreatectomy compared with 9 (14%) without opioid use (P=.0002); the 21 patients also had a higher frequency of postoperative bleeding and early reoperation (8 vs 2, P<.02; 11 vs 3, P=.003, respectively). Mortality and overall morbidity was not significantly different between the 2 groups (4 vs 1, 27 vs 34, respectively). Pain scores improved postoperatively in both groups (P=.001) and was not significantly different between the groups from 12 months onward (median follow-up of 12 months, range, 3-60 months). Twenty percent of patients who used preoperative opioids however reverted to morphine use compared with 6% of patients who had not used opioids. CONCLUSIONS: Patients who used opioids had more advanced disease than patients without opioid use, accounting for part of the postoperative morbidity. Although long-term pain relief was comparable between the 2 groups, maintaining opioid withdrawal was more problematic in those with preoperative opioid use. Earlier referral for resection may be warranted in this group of patients.

Persistent absence of ring-enhancement on CT with an encapsulated brain abscess.

Ring-enhancement on CT (RECT) is generally considered a sine qua non in diagnosing a cerebral abscess. We describe a 16-year-old female who presented with headaches, vomiting and drowsiness, which over 2 weeks rapidly progressed to coma. CT demonstrated a moderately large left frontal extradural abscess, associated with contiguous left frontal osteomyelitis, and underlying frontal and ethmoidal sinusitis. In addition, there was a large circular low density area within the left frontal lobe associated with midline shift that, owing to negative RECT, was assumed to represent nascent ischaemic cerebritis. Despite emergency twist-drill drainage of the extradural abscess, and antibiotic/corticosteroids administration, her clinical condition continued to deteriorate and two episodes of uncal herniation were reversed medically. Repeated CT, however, continued to demonstrate negative enhancement within the left frontal low density, although significant enhancement continued to be apparent with recurrent contiguous extradural suppuration. At definitive craniotomy, a large, well-encapsulated abscess cavity was excised from the left frontal lobe corresponding precisely to the area of previously negative enhancement, along with drainage of the recurrent extradural abscess. Thus, in addition to well-known 'false-positives' for RECT with a cerebral abscess, our case highlights the rare occurrence of a 'false-negative'. A low density mass lesion on CT with persistent negative RECT can neither be assumed to represent early cerebritis nor to exclude a mature abscess.

Pilocytic astrocytoma of the adult--clinical features, radiological features and management.

Pilocytic astrocytoma is a histological subtype of astrocytoma classically located in the cerebellum of children and young adults. Cases occurring over the age of 30 years are rare and have not been classified in terms of their clinical features and management. Suitable cases were identified using diagnostic coding and by reviewing a neuropathology database. Casenotes and neuroradiology were reviewed retrospectively. Ten cases were identified over a 6 year period with an incidence of 0.49 cases per million population per year. Tumours were equally distributed between the supra- and infra-tentorial spaces. The most common symptom was headache occurring in 90%. No patient suffered seizures. Total macroscopic treatment remains the treatment of choice. Pilocytic astrocytoma of the adult is a rare tumour with a favourable prognosis.

Double resection for patients with pancreatic cancer and a second primary renal cell cancer.

BACKGROUND: Reports of synchronous or metachronous double kidney-pancreas cancers are very rare. METHODS: We present 2 patients with renal cell carcinoma and synchronous (1 patient) or metachronous (1 patient) primary pancreatic ductal adenocarcinoma. The patients underwent resection for both cancer types with a worthwhile outcome. RESULTS: The appearance of different primaries in an individual may indicate a genetic predisposition to different neoplasms. The study of double primary cancers is important because it might provide understanding of a shared genetic basis of different solid tumors. CONCLUSIONS: The association between these two cancers demands more detailed epidemiological and molecular investigation. From a clinical viewpoint a resectional policy is recommended.

Minimally invasive retroperitoneal pancreatic necrosectomy.

INTRODUCTION: Open surgery for pancreatic necrosis is associated with considerable morbidity and mortality. We report the results of a recently developed minimally invasive technique that we adopted in 1998. METHODS: A descriptive explanation of the approach is given together with the results of a retrospective analysis of patients who underwent a minimally invasive retroperitoneal pancreatic necrosectomy (MIRP) between August 1998 and April 2002. PATIENTS: There were 24 patients with a median (range) age of 61 (29-75) years. The initial median (range) APACHE II score was 8 (2-21). All patients had infected pancreatic necrosis with at least 50% pancreatic necrosis. In three patients it was not possible to complete the first MIRP because of technical reasons. RESULTS: A total of 88 procedures were performed with a median (range) of 4 (0-8) per patient. Twenty-one (88%) patients developed 36 complications during the course of their illness. Five patients required an additional open procedure: 2 for subsequent distant collections, 2 for bleeding and 1 for persisting sepsis and a distant abscess. Six (25%) patients who had MIRP died. The median (range) post-operative hospital stay was 51 (5-200) days. CONCLUSIONS: MIRP is a new technique that has shown promising results, and could be preferable to open pancreatic necrosectomy in selected patients. However, unresolved issues remain to be overcome and the exact role of MIRP in the management of pancreatic necrosis has yet to be defined.

Duodenum- and spleen-preserving total pancreatectomy for end-stage chronic pancreatitis.

BACKGROUND: Total pancreatectomy may be warranted in patients with advanced chronic pancreatitis in whom partial resection has failed and in those with end-stage pancreatic function. A new operation, duodenum- and spleen-preserving total pancreatectomy, is described. METHODS: Nineteen consecutive patients with chronic pancreatitis who had duodenum- and spleen-preserving total pancreatectomy were studied. RESULTS: There were 15 men and four women with a median age of 40 (range 29-64) years. The aetiology was alcohol misuse in nine, hereditary pancreatitis in five and idiopathic in five patients. All patients had chronic intractable abdominal pain. Six had undergone pancreatic surgery previously and one had had multiple coeliac plexus blocks. There were ten postoperative complications in five patients, and one hospital death. The median hospital stay was 25 (range 10-84) days. There was a reduction in pain (P < 0.001) and analgesic use (P < 0.001) after surgery, and weight gain was noted at 12 and 24 months (P < 0.001). Nine patients required readmission to hospital, four because of surgical complications: adhesional obstruction in one, biliary stricture in two and duodenal obstruction in one. In the other five patients (four of whom had long-standing pre-existing diabetes mellitus) readmission was for better control of pain (three patients), diabetes mellitus (two), and diabetes-associated diarrhoea (two) or gastropathy (one). CONCLUSION: Duodenum- and spleen-preserving total pancreatectomy has a role in selected patients with medically intractable pain from chronic pancreatitis.

Increasing age and APACHE II scores are the main determinants of outcome from pancreatic necrosectomy.

BACKGROUND: The aim of this study was to identify factors associated with death after surgery in patients with extensive pancreatic necrosis. METHODS: Sixty-four patients who underwent pancreatic necrosectomy between 1996 and 2002 were studied. RESULTS: The median age was 60.5 (95 per cent confidence interval (c.i.) 57 to 64) years and 40 patients (62.5 per cent) were tertiary referrals. The initial median Acute Physiology And Chronic Health Evaluation (APACHE) II score was 9 (95 per cent c.i. 7.9 to 10.1) and there were 21 deaths (32.8 per cent). Twenty-eight patients (43.8 per cent) underwent minimally invasive retroperitoneal pancreatic necrosectomy (MIRP) and the remainder had open pancreatic necrosectomy (OPN); 44 (72.1 per cent) of 61 patients had infected pancreatic necrosis at the time of the first procedure. Seven patients who underwent MIRP died compared with 14 after OPN (P = 0.240). Patients who died were older than those who survived, with higher APACHE II scores at presentation, and before and after surgery (P = 0.001). Survivors had significantly longer times to surgery than those who died (P = 0.038). All 21 patients who died required intensive care compared with 26 of 43 survivors (P < 0.001). Thirty of 36 patients who had the OPN procedure required intensive care compared with only 17 of 28 patients who had MIRP (P = 0.042). Logistic regression analysis showed that only postoperative APACHE II score was an independent predictor of increased mortality (P = 0.031). CONCLUSION: Advanced age and increasing APACHE II score, and a need for postoperative intensive care, were the most important predictors of outcome after pancreatic necrosectomy.

Usability of multimedia technology to help caregivers prepare for a crisis.

The objective of the research was to evaluate the usability of a multimedia software application that provides information on coping with difficult situations, dealing with everyday caring problems, and first aid for emergency situations. Casual users (family caregivers, professional caregivers, and older people) were invited to use the software application and complete a questionnaire measuring quality and efficiency in utility and usability. Quantitative data were analyzed using the Statistical Package for the Social Sciences (SPSS) and qualitative data were analyzed by content analysis. Findings indicated the software application to have high global usability, correspond to user expectations, respond quickly, and be visually pleasant and easily understood. The authors conclude that software applications of this type have the potential to increase the quality of life of family caregivers, enhance their coping capacity, and enable them to continue for a longer period in their caring role.

Follow-up after attempted curative surgery for colorectal cancer; postal survey of New Zealand surgeons' practice.

AIMS: The role of follow-up after attempted curative resection of colorectal cancer (CRC) is not clearly defined. We wished to establish the frequency, duration and type of follow-up practised by New Zealand surgeons. METHODS: A postal survey was performed of surgeons on the General Medical Register, asking about the follow-up of asymptomatic patients after potential curative surgery. RESULTS: The response rate was 66%(107/163). There was wide variability in the frequency, duration and type of the indicated follow-up practice. 97% of surgeons followed their patients on average four monthly for the first year. At five years, 79% of surgeons followed their patients. Routine blood tests were performed 54%, while serum carcinoembryonic antigen (CEA) levels were measured by 56% of surgeons for the first two years. 41% performed abdominal imaging in the first two years. 97% of surgeons screened the remaining colon (88% by colonoscopy). 90% performed colonic screening three to five yearly. CONCLUSIONS: Follow-up after potential curative surgery for CRC appears to be widely practised in New Zealand. There is, however, considerable variation between surgeons in the frequency, duration and type of follow-up. This may reflect the conflicting evidence in the literature on the value of follow-up. The outcome of current large prospective randomised trials may confirm whether or not such follow-up is worthwhile and what form it should take.

Technology as an aid to coping with caring: a usability evaluation of a telematics intervention.

This paper presents evaluation data for an interactive software program designed to provide family carers with information, advice and psychological support by way of feedback of their coping capacity. The multimedia program consists of an information-based package that provides carers with advice on health promotion and relaxation and offers them a range of coping strategies (for example, positive self-talk, assertiveness training and relaxation tapes and videos). The program also includes a carer's self-assessment instrument, designed to provide both family and professional carers with information to assess how family carers are coping with their care-giving role. As part of the usability evaluation, casual users (family carers, professional carers and older people) were invited to test the program and were administered a program evaluation questionnaire measuring quality and efficiency in utility and usability. Quantitative data were analysed by using the Statistical Package for the Social Sciences (SPSS) and qualitative data were analysed by content analysis. Findings indicated that the program is visually pleasant, easily understood, responds quickly and corresponds with user expectations. A number of recommendations are made for improvement of the navigation of the program.

Image-guided automated needle biopsy of 106 thoracic lesions: a retrospective review of diagnostic accuracy and complication rates.

We reviewed the diagnostic accuracy and complication rates of transthoracic needle biopsy (TNB) with an automated 18-gauge core biopsy needle and gun, using either fluoroscopic or CT guidance. One hundred six lesions were biopsied in 103 patients between 1992 and 1998. Hard-copy images, imaging reports, pathology reports and clinical notes were reviewed. In 3 patients it was not possible to establish the lesion as either malignant or benign from the available follow-up, so these were removed from the analysis of diagnostic accuracy. Adequate samples for histological diagnosis were obtained in 104 of 106 (98%) biopsies. There were 75 of 85 (88%) true-positive core biopsies for malignant lesions and a specific cell type was identified in 70 of 85 (82%) cases. A specific histological diagnosis was obtained in 12 of 18 (66%) biopsies. There was a 19% rate of pneumothorax with only 2.4% requiring drainage. Minor haemoptysis occurred in 3.8% of procedures. The TNB technique with an automated core biopsy needle provides a high level of diagnostic accuracy, effectively distinguishes cell type in malignancy and provides a definite diagnosis in benign disease more frequently than fine needle aspiration (FNA). There is no increased complication rate compared with FNA.

Percutaneous image-guided biopsy of lung nodules in the assessment of disease activity in Wegener's granulomatosis.

OBJECTIVE: In patients with known Wegener's granulomatosis (WG) and persistent chest radiographic abnormalities, assessment for disease activity is often difficult, prompting the need for histological diagnosis to determine appropriate treatment. Here we report the use of automated image-guided core needle biopsy of pulmonary lesions for the assessment of disease activity in WG, rather than for primary diagnosis. METHODS: Image-guided percutaneous core needle biopsy was performed on five occasions in four patients with thoracic WG and persistent radiographic abnormalities of the chest. Clinical features, indication for biopsy, radiographic abnormalities and pathological findings were recorded. RESULTS: Adequate pathological specimens were obtained, allowing exclusion of infection and tumour. Active chronic inflammation with or without vasculitis was demonstrated in each case, indicating the need for further immunosuppressive therapy. A small pneumothorax following biopsy in one case required no treatment. Follow-up chest imaging revealed a reduction in the extent of thoracic disease following therapy in all cases. CONCLUSIONS: The safety and diagnostic accuracy of image-guided core biopsy of thoracic lesions makes it a useful tool in the assessment of disease activity in WG patients with persistent chest radiographic lesions.

To notify or not to notify: STD patients' perspectives of partner notification in Seattle.

BACKGROUND AND OBJECTIVES: To obtain patients' perspectives on why only some partners are notified in partner-notification programs, the cornerstone of sexually transmitted disease (STD) control, although low proportions of partners are located and evaluated. GOALS: To describe patterns of partner notification reported by persons with STD infection. STUDY DESIGN: In-depth interviews conducted in Seattle with 60 heterosexual men and women with gonorrhea, chlamydial infection, or nongonoccocal urethritis, and 19 men with gonorrhea reporting sex with men (MSM) were tape recorded, transcribed verbatim, and content analyzed. RESULTS: The typical notification pattern was to notify a main partner but not others. Least likely to be notified were partners perceived as transmitters, contacts preceding the onset of symptoms, the oral sex and anonymous contacts of MSM, one-time partners of men, and incarcerated and former partners of women. Fears among young heterosexual participants included gossip and violence (women). Fears among MSM included rejection. CONCLUSIONS: Partner-notification programs should develop innovative approaches for partners perceived as transmitters, oral-sex only contacts of MSM, and contacts preceding symptom onset.
