Surgery in the treatment of acute pancreatitis--minimal access pancreatic necrosectomy

Between 5% and 10% of patients with acute pancreatitis will develop infected pancreatic necrosis. Traditional open surgery for this condition carries a mortality rate of up to 50%, and therefore a number of less invasive techniques have been developed, including radiological drainage and a minimal access retroperitoneal approach. No randomised controlled trials have been published which compare these techniques. Indications for minimal access surgery are the same as for open surgery, i.e. infected pancreatic necrosis or failure to improve with extensive sterile necrosis. Access is obtained to the pancreatic necrosis via the left loin and necrosectomy performed using an operating nephroscope, and this often requires several procedures to remove all necrotic tissue. The cavity is continuously irrigated on the ward in between procedures. The results of this approach are encouraging, with less systemic upset to the patient, a lower incidence of post-operative organ failure when compared with open surgery, and a reduced requirement for ITU support. There is also a trend towards a lower mortality rate, although this does not reach statistical significance on the data published so far. Current evidence suggests that a minimal access approach to pancreatic necrosis is feasible, well tolerated and beneficial for the patient when compared with open surgery.

A comparison of two invasive techniques in the management of intractable pain due to inoperable pancreatic cancer: neurolytic celiac plexus block and videothoracoscopic splanchnicectomy

BACKGROUND AND AIMS

Pancreatic cancer is characterized by a constant deterioration in quality of life, excruciating pain and progressive cachexia. The aim of this study was to compare the effectiveness of two invasive methods of pain treatment in these patients: neurolytic coeliac plexus block (NCPB) and videothoracoscopic splanchnicectomy (VSPL) to a conservatively treated control group concerning pain, quality of life and opiates' consumption.

PATIENTS AND METHODS

Fifty nine patients suffering from pain due to inoperable pancreatic cancer were treated invasively with NCPB (N=35) or VSPL (N=24) in two non-randomised, prospective, case-controlled protocols. Intensity of pain (VAS-pain), quality of life (FACIT and QLQ C30) and opioid intake were compared between the groups and to a control group of patients treated conservatively before the procedure and after 2 and 8 weeks of follow-up. The analysis was performed retrospectively using meta-analysis statistics.

RESULTS

Both methods of invasive pain treatment resulted in significant reduction of pain (VSPL effect size=11.27, NCPB effect size=7.29) and fatigue (effect sizes, respectively, 1.23 and 3.37). NCPB improved also significantly physical, emotional and social well-being (effect sizes, respectively, 2.37, 4.13 and 7.51) which was not observed after VSPL. No influence on ailments characteristic for the disease was demonstrated. Mean daily opioid consumption was significantly decreased after both procedures. There was no perioperative mortality and no major morbidity.

CONCLUSION

Both NCPB and VSPL provide significant reduction of pain and improvement of quality of life in inoperable pancreatic cancer patients. They present rather similar efficacy, but lower invasiveness of NCPB, in combination with its more positive effect on quality of life, pre-disposes it as being the preferred method.

Meta-analysis of the value of somatostatin and its analogues in reducing complications associated with pancreatic surgery

BACKGROUND

The role of somatostatin and its analogues in reducing complications after pancreatic resection is controversial. This is a meta-analysis of the evidence of benefit.

METHODS

A literature search using Medline and ISI Proceedings with exploration of the references identified 22 studies. Of these, ten met the inclusion criteria for data extraction. Estimates of effectiveness were performed using fixed- and random-effects models. The effect was calculated as an odds ratio (OR) with 95 per cent confidence intervals (c.i.) using the Mantel-Haenszel method. Level of significance was set at P < 0.050.

RESULTS

Outcomes for 1918 patients were compared. Somatostatin and its analogues did not reduce the mortality rate after pancreatic surgery (OR 1.17 (0.70 to 1.94); P = 0.545) but did reduce both the total morbidity (OR 0.62 (0.46 to 0.85); P = 0.003) and pancreas-specific complications (OR 0.56 (0.39 to 0.81); P = 0.002). Somatostatin and its analogues reduced the rate of biochemical fistula (OR 0.45 (0.33 to 0.62); P < 0.001) but not the incidence of clinical anastomotic disruption (OR 0.80 (0.44 to 1.45); P = 0.459).

CONCLUSION

Somatostatin and its analogues reduce the incidence of complications after surgery.

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.

Early and late complications after pancreatic necrosectomy

BACKGROUND

Surgery for pancreatic necrosis is associated with a high morbidity and mortality. The aim of this study was to review the incidence of early and late complications after pancreatic necrosectomy in a large contemporary series of patients.

METHODS

The clinical outcomes of 88 patients who underwent pancreatic necrosectomy between 1997 and 2003 were reviewed.

RESULTS

The median age was 55.5 (range, 18-85) years, 54 (61%) were males, 68 (77%) had primary pancreatic infection, 71 (81%) had >50% necrosis, and the median admission Acute Physiology and Chronic Health Evaluation score was 9 (range, 1-21). Median time to surgery was 31 (range, 1-161) days; 47 patients underwent minimally invasive necrosectomy and 41 open necrosectomy; 81 (92%) of patients had complications postoperatively, and 25 (28%) died. Multiorgan failure (odds ratio = 3.4, P = .05) and hemorrhage (odds ratio = 6.1, P = .03) were the only independent predictors of mortality. During a median follow-up of 28.9 months, 39 (62%) of 63 surviving patients had one or more late complications: biliary stricture in 4 (6%), pseudocyst in 5 (8%), pancreatic fistula in 8 (13%), gastrointestinal fistula in 1 (2%), delayed collections in 3 (5%), and incisional hernia in 1 (2%); intervention was required in 10 (16%) patients. Sixteen (25%) of 63 surviving patients developed exocrine insufficiency, and 19 (33%) of 58 without prior diabetes mellitus developed endocrine insufficiency.

CONCLUSIONS

Almost all patients undergoing necrosectomy developed significant early or late complications or both. Multiorgan failure and postoperative hemorrhage were independent predictors of mortality. Long-term follow-up was important because 62% developed complications, and 16% of those with complications required surgical or endoscopic intervention.

Serum CA19-9 measurement increases the effectiveness of staging laparoscopy in patients with suspected pancreatic malignancy

BACKGROUND/AIMS

Staging laparoscopy for suspected pancreatic neoplasia is not widely accepted due to its low yield. The aim of this study was to determine if serum carbohydrate antigen (CA19-9) levels could be used to improve the selection of patients for staging laparoscopy.

METHODS

The data from a prospectively collected database (1997-2004) with 159 patients who had computed tomography-predicted resectable disease and who had undergone laparoscopic staging were analysed to determine if a low preoperative CA19-9 level (< or =150 kU/l, or < or =300 kU/l with a bilirubin >35 micromol/l) identified patients in whom laparoscopy was not useful.

RESULTS

The CA19-9 level was >150 kU/l in 96 patients of whom 75 (78%) were considered resectable following laparoscopic assessment. There were 63 patients with a CA19-9 < or =150 kU/l of whom 60 (95%) were considered resectable following laparoscopic assessment. The sensitivity, specificity, positive predictive value and negative predictive value for CA19-9 < or =150 kU/l in predicting that laparoscopic assessment would judge patients as resectable were 44, 88, 95 and 22%, respectively. A cut-off level of < or =300 kU/l in patients with a bilirubin >35 micromol/l produced values of 30, 94, 94 and 28%, respectively. By using CA19-9 < or =150 kU/l, laparoscopy could have been avoided in 40% of patients, increased to 55% of patients with adjustment for the presence of jaundice; concomitantly, the yield from laparoscopy would have been increased from 15 to 22 and 25%, respectively.

CONCLUSION

Use of serum CA19-9 levels would increase the efficiency of laparoscopic staging in patients with suspected pancreatic malignancy.

Positron emission tomography does not add to computed tomography for the diagnosis and staging of pancreatic cancer

BACKGROUND

Positron emission tomography (PET) has been proposed for pancreatic cancer diagnosis and staging.

METHODS

112 patients with suspected pancreatic cancer underwent 18F-fluoro-2-deoxy-D-glucose gamma camera PET and computed tomography (CT), of whom 62 also had laparoscopic ultrasonography and 70 underwent abdominal exploration for potential resection. The final diagnosis was malignancy in 78 and benign disease in 34 patients (25 with chronic pancreatitis).

RESULTS

The diagnostic sensitivity and specificity for PET were 73 and 60% compared to 89 and 65% for CT respectively (Cohen's kappa = 0.59). In 30 patients CT was equivocal with cancer in 14 and benign disease in 16. PET correctly diagnosed 13 of these patients (cancer in 6 and benign disease in 7), interpreted 4 as equivocal (cancer in 3 and benign disease in 1) but was incorrect in the remaining 13 patients (cancer in 5 and benign disease in 8). The sensitivity and specificity for detecting small volume metastatic disease were 20 and 94% for CT and 22 and 91% for PET, respectively.

CONCLUSION

PET had a similar accuracy to that of CT for imaging pancreatic cancer but it did not provide any additional information in patients with equivocal CT findings and currently would seem of little benefit for the staging of pancreatic cancer.

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.

Surgical palliation for unresectable hilar cholangiocarcinoma

The majority of patients who present with hilar cholangiocarcinoma will have incurable disease and require only palliation. Efficient relief of disabling symptoms is required with minimal morbidity and mortality and can be achieved by either surgical or non-operative options. A review of the indications, anatomical considerations and surgical techniques is presented. Segment III cholangio-jejunostomy is the most frequently used surgical bypass procedure and in those patients with an expected survival of more than 6 months, surgical palliation offers good quality and long-lasting palliation. There is a need for randomized controlled data to define the optimal role of surgical palliation in this difficult disease.

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.

Laparoscopy and laparoscopic ultrasound in the evaluation of pancreatic and periampullary tumours

BACKGROUND AND AIMS

The pre-operative determination of resectability of pancreatic and peri-ampullary neoplasia assists the selection of patients for surgical or non-surgical treatment. This study investigated whether the addition of laparoscopy with laparoscopic ultrasound to dual-phase helical CT could improve the accuracy of assessment of resectability.

PATIENTS AND METHODS

Prospective study of 305 patients referred to a single unit for consideration of pancreatic resection who underwent dual-phase helical CT scanning +/- laparoscopy with laparoscopic ultrasound. Data were collected on patient demographics, CT findings, assessment of operability, laparoscopic assessment (LA), surgical procedures and histology.

RESULTS

LA was undertaken in 239/305 patients, 190 of whom were considered CT resectable, and 49 CT unresectable. Of the 190 CT resectable patients, LA correctly identified unresectability in 28 (15%: metastases in 15; vascular encasement in 6; anaesthesia for laparoscopy found 7 unfit for major resection) and incorrectly in 2 (vascular encasement), but did not identify unresectability in 33; LA correctly confirmed resectability in the remainder (prediction improved, chi(2) = 9.73, p < 0.01). Of the 49 CT unresectable patients, LA correctly identified resectability in 4, and incorrectly in 12, and correctly identified unresectability in the remaining 33. Sixty-six of the 305 patients did not undergo LA, of whom 23 underwent resection.

CONCLUSION

When added to dual-phase helical CT, laparoscopy with laparoscopic ultrasound provides valuable information that significantly improves the selection of patients for surgical or non-surgical treatment.

Fungal infection but not type of bacterial infection is associated with a high mortality in primary and secondary infected pancreatic necrosis

INTRODUCTION

Knowledge of microbiology in the prognosis of patients with necrotizing pancreatitis is incomplete.

AIM

This study compared outcomes based on primary and secondary infection after surgery for pancreatic necrosis.

METHOD

From a limited prospective database of pancreatic necrosectomy, a retrospective case note review was performed (October 1996 to April 2003).

RESULTS

55 of 73 patients had infected pancreatic necrosis at the first necrosectomy. 25 of 47 patients had resistant bacteria to prophylactic antibiotics (n = 21) or did not receive prophylactic antibiotics (n = 4), but this was not associated with a higher mortality (9 of 25) compared to those with sensitive organisms (4 of 22). Patients with fungal infection (n = 6) had a higher initial median (95% CI) APACHE II score compared to those without (11 (9-13) verus 8.5 (7-10), p = 0.027). Five of six patients with fungal infection died compared to 13 of 47 who did not (p = 0.014). With the inclusion of secondary infections 21 (32%) of 66 patients had fungal infection with 10 (48%) deaths compared to 11 (24%) of 45 patients without fungal infection (p = 0.047).

CONCLUSION

Whether associated with primary or secondary infected pancreatic necrosis, fungal but not bacterial infection was associated with a high mortality.

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.

Diagnosis, treatment and outcome of pancreatoblastoma

BACKGROUND

Pancreatoblastoma is a rare tumour mainly presenting in childhood but also in adults.

OBJECTIVES

The aim was to determine the clinical course of pancreatoblastoma by an analysis of reported cases.

METHODS

Patients with pancreatoblastoma were identified from Medline and combined with patients identified from the Royal Liverpool University Hospital.

RESULTS

There were 153 patients with a median (range) age at presentation of 5 (0-68) years and a male:female ratio of 1.14:1. The most frequent site was the head of pancreas (48/123, 39%). The median and 5-year (95% CI) survival rates were 48 months and 50% (37-62%) respectively. At presentation there were 17 (17%) out of 101 patients with metastases, the liver being the commonest site (15/17, 88%). On univariate analysis, factors associated with a worse prognosis were synchronous (p = 0.05) or metachronous metastases (p < 0.001), non-resectable disease at presentation (p < 0.001) and age > 16 years at time of presentation (p = 0.02). On multivariate analysis, resection (p = 0.006) and metastases post-resection (p = 0.001) but not local recurrence influenced survival.

CONCLUSIONS

Pancreatoblastoma is one of the pancreatic tumours with a relatively good prognosis. The treatment of choice is complete resection with long-term follow-up aiming to treat any early local recurrence or metastasis.

Hereditary pancreatic endocrine tumours

The two main types of hereditary pancreatic neuroendocrine tumours are found in multiple endocrine neoplasia type 1 (MEN-1) and von Hippel-Lindau disease (VHL), but also in the rarer disorders of neurofibromatosis type 1 and tuberous sclerosis. This review considers the major advances that have been made in genetic diagnosis, tumour localization, medical and surgical treatment and palliation with systemic chemotherapy and radionuclides. With the exception of the insulinoma syndrome, all of the various hormone excess syndromes of MEN-1 can be treated medically. The role of surgery however remains controversial ranging from no intervention (except enucleation for insulinoma), intervening for tumours diagnosed only by biochemical criteria, intervening in those tumours only detected radiologically (1-2 cm in diameter) or intervening only if the tumour diameter is > 3 cm in diameter. The extent of surgery is also controversial, although radical lymphadenectomy is generally recommended. Pancreatic tumours associated with VHL are usually non-functioning and tumours of at least 2 cm in diameter should be resected. Practice guidelines recommend that screening in patients with MEN-1 should commence at the age of 5 years for insulinoma and at the age of 20 years for other pancreatic neuroendocrine tumours and variously at 10-20 years of age for pancreatic tumours in patients with VHL. The evidence is increasing that the life span of patients may be significantly improved with surgical intervention, mandating the widespread use of tumour surveillance and multidisciplinary team management.

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.

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.

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.

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 &lt; 0·001) and analgesic use (P &lt; 0·001) after surgery, and weight gain was noted at 12 and 24 months (P &lt; 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.
