RESUMEN
Extrapleural solitary fibrous tumor (SFT) is an uncommon mesenchymal neoplasm, presenting most commonly in the intrathoracic sites but which has been reported at numerous extrathoracic locations. The majority of intra-thoracic SFTs are benign, but 10%-15% behave aggressively. We report a case of primary hepatic SFT with histologically benign and malignant areas. A 65-year-old man underwent an abdominal CT scan following a cerebrovascular accident, which demonstrated a sharply demarcated large liver mass with a heterogenous enhancing area and occupying most of the left lobe of the liver. Histological examination following a hemihepatectomy showed an SFT with morphological patterns ranging from benign to malignant areas, including pleomorphism, increased cellularity, herringbone pattern, necrosis and a raised mitotic count. On review of the literature, only an occasional case report with malignant areas in a hepatic SFT was identified. This case highlights that SFT should be included in the differential diagnosis of a hepatic spindle cell lesion, and that on rare occasions, malignant areas can occur in this already uncommon neoplasm.

CONTEXT: We describe a late complication of the pancreatico-gastrostomy (PG) anastomosis following pancreatico-duodenectomy (PD). CASE REPORT: A percutaneous endoscopic gastrostomy (PEG) feeding tube was inserted many months post-operatively. In this patient activated pancreatic enzymes eroded the gastrostomy tract, resulting in pain, recurrent infection and eventual removal of the gastrostomy tube. CONCLUSIONS: Where surgical insertion of a feeding jejunostomy is not viable or deemed too high risk after Whipple or PPPD, we recommend careful consideration of PEG tube insertion in patients with PG reconstruction. If a PEG is used the prophylactic use of Lanreotide is recommended.

Chemotherapy for metastatic colorectal cancer is constantly advancing. Its use in the adjuvant and neoadjuvant setting is also increasing. However, while long-term survival is improving, clinicians must be aware of the possible adverse events that can occur when treating with adjuvant chemotherapy and liver resection. We present a case of a life-threatening delayed bile leak following a liver resection for metastatic colorectal cancer in association with adjuvant treatment with bevacizumab. A 53-year-old man was treated with neoadjuvant bevacizumab followed by liver resection for metastatic colorectal cancer. He made an uneventful recovery. Forty-three days post-surgery he received bevacizumab and developed acute life-threatening bile leaks from the cut surface of the liver. He spent a total of 65 days in hospital, and required ERCP repeatedly and eventually had a repeat liver resection to resolve the bile leak. This case reports a possible association between bevacizumab and a life threatening delayed bile leak following liver resection.

Recent studies have indicated that preoperative biliary drainage (PBD) should not be routinely performed in all patients suffering from obstructive jaundice before pancreatic surgery. The severity of jaundice that mandates PBD has yet to be defined. The evaluated paper examines the impact of PBD on intra-operative, and post-operative outcomes in patients initially presenting with severe obstructive jaundice (bilirubin ≥250 µmol/L). In this key paper evaluation, the impact of PBD versus a direct surgery (DS) approach is discussed. The arguments for and against each approach are considered with regards to drainage associated morbidity and mortality, resection rates, survival and the impact of chemotherapy and malnutrition. Concentrating on resectable head of pancreas tumors, this mini-review aims to scrutinize the authors' recommendations, alongside those of prominent papers in the field.

BACKGROUND: Left hepatic trisectionectomy (LHT) is a complex hepatic resection; its' role and outcomes in hepatobiliary malignancies remains unclear. MATERIALS AND METHODS: All patients undergoing LHT at the tertiary HPB referral unit at RSCH, Guildford, UK from September 1996 to October 2015 were included. Data were collected from a prospectively maintained database. RESULTS: Twenty-eight patients underwent LHT. The M:F ratio was 1.8:1. Median age was 60 years (range 43-76 years). Diagnoses included colorectal liver metastases (CRLM; n = 20); cholangiocarcinoma (CCA; n = 4); and other (neuroendocrine tumour metastases (NET; n = 3) and breast metastases (n = 1)). Median duration of surgery was 270 min (range 210-585 min). Median blood loss was 750 ml (300-2400 ml) with a perioperative transfusion rate of 21% (n = 6/28). The rate of all post-operative complications was 21% for all patients, and given the extensive resection performed four patients (14%) developed varying degrees of hepatic insufficiency. One patient with cholangiocarcinoma developed severe hepatic insufficiency, which was fatal within 90 days of surgery. 1 and 3-year survivals were 92% and 68% respectively. CONCLUSION: This study supports LHT in patients with significant tumour burden. Despite extensive resection, our favourable morbidity and mortality rates show this is a safe and beneficial procedure for patients with all hepatobiliary malignancies. Given the nature of resection the incidence of post-operative hepatic insufficiency is higher than less extensive hepatic resections.
RESUMEN
Acute pancreatitis is a common general surgical emergency presentation. Up to 20% of cases are severe and can involve necrosis with high associated morbidity and mortality. It is most commonly due to gallstones and excess alcohol consumption. All patients with acute pancreatitis need to be scored for severity and patients with severe acute pancreatitis should be managed on the high dependency unit. The mainstay of early treatment is supportive, with care to ensure strict fluid balance and optimisation of end organ perfusion. There is no role for early antibiotic use in acute necrotising pancreatitis and antibiotics should only be used in the presence of positive cultures. Nutritional support is vitally important in improving outcomes in necrotising pancreatitis. This should ideally be provided enterally using an naso-jejunal tube if the patient cannot tolerate oral intake. Patients with significant early necrosis, persisting organ dysfunction, infected walled off necrosis requiring intervention or haemorrhagic pancreatitis should be referred to a regional hepato-pancreatico-biliary unit for advice or transfer. Percutaneous and endoscopic necrosectomy has replaced open surgery due to improved outcomes. Acute necrotising pancreatitis remains a complex surgical emergency with high morbidity and mortality that requires a multidisciplinary approach to attain optimum outcomes. The mainstay of treatment is supportive care and nutritional support. Patients with significant pancreatic necrosis or infected collections requiring drainage require input from a tertiary HPB unit to guide management.
RESUMEN
Granulosa cell tumours of the ovary are rare. They are considered low-grade malignant cancers and infrequently metastasise to the liver. We present our experience of a case with a grade 1, stage 1 granulosa cell tumour of the ovary that systemically recurred 15 years following surgical resection. The patient went on to have a debulking hepatic resection 21 years following initial surgery despite a 6-year-long palliative diagnosis.

BACKGROUND: Retroperitoneal enterogenous cysts are uncommon and adenocarcinoma within such cysts is a rare complication. CASE PRESENTATION: We present the third described case of a retroperitoneal enterogenous cyst with adenocarcinomatous changes and only the second reported case whereby the cyst was not arising from any anatomical structure. CONCLUSION: This case demonstrates the difficulties in making a diagnosis as well as the importance of a multi-disciplinary approach, and raises further questions regarding post-operative treatment with chemotherapy.
RESUMEN
INTRODUCTION: Liver resection is proved to offer potential long-term survival for colorectal liver metastases (CRLM). Accurate radiological assessment is vital to enable an appropriate surgical approach. The role of intraoperative ultrasound (IOUS) has been controversial. This study was designed to analyse the accuracy of IOUS compared with that of preoperative imaging (POI) in these patients. MATERIALS AND METHODS: A prospective analysis of 51 consecutive patients who underwent liver resection for CRLM was undertaken. The accuracy of POI and IOUS were correlated and compared with histopathological analysis. Statistical analyses included t-tests, to compare continuous variables, and chi-square and Fisher's exact tests to compare categorical variables. p<0.05 was considered significant RESULTS: POI correlated with histology in 35 patients (68.6%). The sensitivity and specificity were 82.4% and 86.3% respectively. IOUS correlated with histology in 31 (60.8%) patients. The sensitivity and specificity were 84.3% and 76.5% respectively. There was no difference in accuracy between modalities. The accuracy of POI combined with IOUS correlated with histology in 40 patients (78.4%). The sensitivity and specificity were 88.2% and 84.3% respectively. The accuracy of combined modalities was significantly greater than IOUS or POI alone. CONCLUSIONS: POI combined with IOUS may significantly increase the diagnostic accuracy of patients undergoing liver resection for CRLM.

INTRODUCTION: At present, liver resection offers the best long-term outcome and only chance for cure in patients with colorectal liver metastases. However, there are no large series that report the early and long-term outcomes of patients who require simultaneous diaphragm excision. This study was designed to investigate these patients. PATIENTS AND METHODS: A total of 285 consecutive liver resections were performed over a 10-year period. Of these, 258 had liver resections alone and 27 underwent liver resection and simultaneous diaphragm excision. Data were collected prospectively and analysed retrospectively. Pre-operative assessment was standardised. The outcomes between the two groups were compared. RESULTS: There was no difference in age, hospital stay or intra-operative blood loss. The diaphragm was histologically involved in four out of 27 resections. As a result, the cancer involved resection margin incidence was greater in the liver resection and diaphragm excision group (14.8% versus 3.9%; P = 0.12). The median tumour size was also different between the two groups (60 mm versus 30 mm; P = 0.001). The liver and diaphragm resection group had a greater peri-operative complication rate (44.4% versus 21.3%; P = 0.02) and mortality (7.4% versus 1.6%; P = 0.25). Overall and disease-free survival was significantly worse in the group who underwent simultaneous diaphragm excision and liver resection (P = 0.04 and P = 0.005, respectively). Diaphragm invasion was found to be an independent predictor of poor overall outcome (P = 0.02). CONCLUSIONS: Liver resection and simultaneous diaphragm excision have a greater incidence of peri-operative morbidity and mortality and a significantly worse long-term outcome compared with liver resection alone. However, these data suggest that liver resection in the presence of diaphragm invasion may still offer a favourable outcome compared with chemotherapy treatment alone. Therefore, we believe that diaphragm involvement by tumour should not be a contra-indication to hepatectomy.

INTRODUCTION: Providing nutrition for patients following pancreaticoduodenectomy (PD) is vital but can be challenging. Due to the lack of UK national guidelines for the provision of nutrition and nutritional pre-operative assessment regarding PD, a national survey was conducted. PATIENTS AND METHODS: A questionnaire was sent to the Department of Nutrition and Dietetics at each of the 31 specialist pancreatic centres listed with the Pancreatic Society of Great Britain and Ireland. Questions were asked regarding the nutritional assessment and treatment of patients undergoing classical PD and pylorus-preserving PD (PPPD) resections. RESULTS: Twenty-two centres responded to the questionnaire. With regard to PD and PPPD, 82% routinely feed patients following resection, 32% have a regimen for staring feeds, 18% carry out pre-operative nutritional assessment, five centres have funding for an hepatobiliary dietition, and only four centres have a specialist hepatobiliary dietition employed. There was no consensus regarding the type or route of feeding, and at least one centre reported using parenteral nutrition exclusively. CONCLUSIONS: Very few centres in the UK have funding for a hepatobiliary dietition. Hence pre-operative nutritional assessment in patients undergoing PD and PPPD does not receive much input. Although the importance of postoperative feeding in these patients is appreciated in all major units, there is no consensus with regards to feeding regimens. The authors hope this observational study will address these issues with this important message and stimulate further study in this area.

BACKGROUND: Liver resection is an accepted treatment modality for malignant disease of the liver. However, because of its potential morbidity and mortality, the practice of liver resection in benign disease is more controversial. This study was designed to assess the early outcomes of 79 consecutive liver resections for benign disease over a 12-year period and compare these with early outcomes of 390 consecutive liver resections for metastatic colorectal cancer (MCRC) during the same period. METHODS: Consecutive liver resections were carried out in a single hepatopancreatobiliary (HPB) centre between 1996 and 2008. Patient demographics and early outcomes were recorded. Statistical analyses were performed using spss (Version 15). P < 0.05 was considered to be significant. RESULTS: There was no difference in median age between the benign group vs. the MCRC group (P = 0.181). However, there was a significant trend towards a lower ASA grade in the benign group (P < 0.001). There was no difference in median blood loss (P = 0.139) or hospital stay (P = 0.262). Morbidity rates were 8.9% in the benign group and 20.5% in the MCRC group (P = 0.002). The rate of serious complications was 1.3% in the benign group compared with 4.4% in the MCRC group (P = 0.041). There were no postoperative deaths in the benign group and eight (2%) in the MCRC group (P = 0.004). CONCLUSIONS: Liver resection for benign liver tumours can be undertaken with a mortality rate approaching zero and minimal morbidity in specialist HPB units.
RESUMEN
INTRODUCTION: Centres with high volumes of high-risk surgery have significantly better outcomes than low-volume centres for pancreatic resection, oesophagectomy and pelvic exenteration. However, this has not to date been conclusively demonstrated for hepatic resection. With increased experience, operative practice can change. The use of the Pringle manoeuvre reduced substantially over a 12-year period in a single centre as it was felt anecdotally that its use increased the incidence of hepatic insufficiency and operative mortality. This study was designed to review 12 years of experience in a single hepatobiliary centre. PATIENTS AND METHODS: Data regarding 526 consecutive liver resections were prospectively recorded and retrospectively analysed in a high-volume referral unit over a 12-year period. Patients' demographics, operative mortality and morbidity were analysed on an annual basis. RESULTS: Overall peri-operative mortality was 1.9%. Operative mortality in the first 6 years compared to the latter 6 years was 4.1% and 1.2%, respectively (P = 0.13). The morbidity rate was 26.8% and 20.3% in the first and second halves of the study, respectively (P = 0.15). With increased experience, intra-operative blood loss and patients receiving blood transfusions decreased (P = 0.047 and 0.03, respectively) while the number of intra-operative Pringle manoeuvres also decreased (P < 0.0001). Hospital stay decreased significantly over the 12 years (P = 0.049). CONCLUSIONS: High-volume centres are the safest environment for hepatic resection. With increased experience, it may be possible to reduce the intra-operative use of the Pringle manoeuvre without increasing the intra-operative blood loss. This may be associated with a decrease in hepatic insufficiency and peri-operative mortality.

OBJECTIVES: Chronic pancreatitis (CP) is common. It is associated with a substantial morbidity, including malnutrition, malabsorption, pseudocysts, metabolic disturbances, and intractable abdominal pain. Approximately 5% of patients with CP are refractory to nutritional support and opiate analgesia, making management challenging.Pancreatic rest can provide symptomatic relief. However, achieving simultaneous pancreatic rest and adequate nutritional support in these patients is difficult. We describe a technique for providing nutritional support and pancreatic rest in patients with intractable symptomatic CP. METHODS: Three patients with symptomatic CP refractory to standard treatment were included in the study. All 3 patients had masses associated with the pancreas. Symptom relief and adequate nutritional support were achieved by inserting a long-term nasojejunal (NJ) tube (Flocare Bengmark, Nutricia Clinical Care, United Kingdom) under ambulatory endoscopic guidance. Data were recorded prospectively. RESULTS: Long-term NJ tube feeding achieved pancreatic rest and significant symptomatic relief while delivering adequate nutritional support. Pseudocyst size decreased substantially in 2 patients. The third patient was found to have pancreatic carcinoma after pancreaticoduodenectomy. CONCLUSIONS: In patients with symptomatic CP refractory to standard nutritional support and opiate analgesia, long-term NJ tube feeding can be a cheap, well-tolerated, safe, and effective method of providing adequate nutritional support and substantially relieving intractable symptoms.

A small proportion of patients with metastatic renal cell carcinoma have operable liver metastases, as there is often multiple dissemination within the liver and to other organs. We present a case of a solitary liver metastasis found incidentally 20 years after radical nephrectomy for a chromophobe renal cell carcinoma. The patient underwent a liver resection with tumor-free margins and recovered uneventfully. Time will tell if this was oncologically successful.

BACKGROUND: The management of patients with colorectal liver metastases and loop ileostomies remains controversial. This study was performed to assess the outcome of combined liver resection and loop ileostomy closure. METHODS: Analysis of prospectively collected perioperative data, including morbidity and mortality, of 283 consecutive hepatectomies for colorectal liver metastases was undertaken. Consecutive liver resections were performed from 1996 to 2006 in one centre by a single surgeon (NDK). Fourteen of these patients had combined liver resection and ileostomy closure. Case-matched analysis was undertaken. RESULTS: Six (2.2%) patients died in the hepatectomy only group and none died in the combined group. There was no difference in operative blood loss between the two groups (0.09). Perioperative morbidity was 36% in the combined group and 23% in the hepatectomy alone group (P = 0.33). Mean hospital stay was 14 days in the combined group and 11 days in the hepatectomy only group (P = 0.046). Case-matched analysis showed a significant increase in hospital stay (P = 0.03) and complications (P = 0.049) in the combined group. CONCLUSION: In patients with CRLM, combined liver resection and closure of ileostomy may be associated with a higher operative morbidity and a prolonged hospital stay.
RESUMEN
Patients with coeliac artery occlusion often remain asymptomatic due to the rich collateral blood supply (pancreaticoduodenal arcades) from the superior mesenteric artery. However, division of the gastroduodenal artery (GDA) during pancreaticoduodenectomy may result in compromised blood supply to the liver, stomach and spleen. Postoperative complications associated with this condition are rarely reported in the literature. We report two cases of coeliac artery occlusion encountered during pancreaticoduodenectomy, one of which was complicated by hepatic ischaemia and total gastric infarction postoperatively. Based on our experience and review of the literature, a management algorithm for coeliac artery stenosis encountered during pancreaticoduodenectomy is proposed.
RESUMEN
INTRODUCTION: Gallstone ileus is an uncommon complication of cholelithiasis but an established cause of mechanical bowel obstruction in the elderly. Perforation of the small intestine proximal to the obstructing gallstone is rare, and only a handful of cases have been reported. We present two cases of perforation of the jejunum in gallstone ileus, and remarkably in one case, the gallstone ileus caused perforation of a jejunal diverticulum and is to the best of our knowledge the first such case to be described. CASE PRESENTATIONS: Case 1A 69 year old man presented with two days of vomiting and central abdominal pain. He underwent laparotomy for small bowel obstruction and was found to have a gallstone obstructing the mid-ileum. There was a 2 mm perforation in the anti-mesenteric border of the dilated proximal jejunum. The gallstone was removed and the perforated segment of jejunum was resected.Case 2A 68 year old man presented with a four day history of vomiting and central abdominal pain. Chest and abdominal radiography were unremarkable however a subsequent CT scan of the abdomen showed aerobilia. At laparotomy his distal ileum was found to be obstructed by an impacted gallstone and there was a perforated diverticulum on the mesenteric surface of the mid-jejunum. An enterolithotomy and resection of the perforated small bowel was performed. CONCLUSION: Gallstone ileus remains a diagnostic challenge despite advances in imaging techniques, and pre-operative diagnosis is often delayed. Partly due to the elderly population it affects, gallstone ileus continues to have both high morbidity and mortality rates. On reviewing the literature, the most appropriate surgical intervention remains unclear.Jejunal perforation in gallstone ileus is extremely rare. The cases described illustrate two quite different causes of perforation complicating gallstone ileus. In the first case, perforation was probably due to pressure necrosis caused by the gallstone. The second case was complicated by the presence of a perforated jejunal diverticulum, which was likely to have been secondary to the increased intra-luminal pressure proximal to the obstructing gallstone.These cases should raise awareness of the complications associated with both gallstone ileus, and small bowel diverticula.
