Abstract
BACKGROUND Many patients with bi-lobar liver tumours are not eligible for liver resection due to an insufficient future liver remnant (FLR). To reduce the risk of posthepatectomy liver failure and the primary cause of death, regenerative procedures intent to increase the FLR before surgery. The aim of this systematic review is to provide an overview of the available literature and outcomes on the effectiveness of simultaneous portal and hepatic vein embolization (PVE/HVE) versus portal vein embolization (PVE) alone. METHODS A systematic literature search was conducted in PubMed, Web of Science, and Embase up to September 2022. The primary outcome was resectability and the secondary outcome was the FLR volume increase. RESULTS Eight studies comparing PVE/HVE with PVE and six retrospective PVE/HVE case series were included. Pooled resectability within the comparative studies was 75 per cent in the PVE group (n = 252) versus 87 per cent in the PVE/HVE group (n = 166, OR 1.92 (95% c.i., 1.13-3.25)) favouring PVE/HVE (P = 0.015). After PVE, FLR hypertrophy between 12 per cent and 48 per cent (after a median of 21-30 days) was observed, whereas growth between 36 per cent and 67 per cent was reported after PVE/HVE (after a median of 17-31 days). In the comparative studies, 90-day primary cause of death was similar between groups (2.5 per cent after PVE versus 2.2 per cent after PVE/HVE), but a higher 90-day primary cause of death was reported in single-arm PVE/HVE cohort studies (6.9 per cent, 12 of 175 patients). CONCLUSION Based on moderate/weak evidence, PVE/HVE seems to increase resectability of bi-lobar liver tumours with a comparable safety profile. Additionally, PVE/HVE resulted in faster and more pronounced hypertrophy compared with PVE alone.

Abstract
STUDY PURPOSE The DRAGON 1 trial aims to assess training, implementation, safety and feasibility of combined portal- and hepatic-vein embolization (PVE/HVE) to accelerate future liver remnant (FLR) hypertrophy in patients with borderline resectable colorectal cancer liver metastases. METHODS The DRAGON 1 trial is a worldwide multicenter prospective single arm trial. The primary endpoint is a composite of the safety of PVE/HVE, 90-day mortality, and one year accrual monitoring of each participating center. Secondary endpoints include: feasibility of resection, the used PVE and HVE techniques, FLR-hypertrophy, liver function (subset of centers), overall survival, and disease-free survival. All complications after the PVE/HVE procedure are documented. Liver volumes will be measured at week 1 and if applicable at week 3 and 6 after PVE/HVE and follow-up visits will be held at 1, 3, 6, and 12 months after the resection. RESULTS Not applicable. CONCLUSION DRAGON 1 is a prospective trial to assess the safety and feasibility of PVE/HVE. Participating study centers will be trained, and procedures standardized using Work Instructions (WI) to prepare for the DRAGON 2 randomized controlled trial. Outcomes should reveal the accrual potential of centers, safety profile of combined PVE/HVE and the effect of FLR-hypertrophy induction by PVE/HVE in patients with CRLM and a small FLR.

Abstract
Pancreaticoduodenal and gastroduodenal artery aneurysms are rare but require early radiological or surgical intervention due to a high risk (61%) of rupture. A 71-year-old woman presented with an incidental 30-mm aneurysm arising from the inferior pancreaticoduodenal artery associated with coeliac axis stenosis. She underwent embolisation of the pancreaticoduodenal aneurysm, but the coeliac axis stenosis was not amenable to radiological intervention. She remained well at six months of follow-up and a repeat computed tomography angiogram six months later reported stable appearances. The management of pancreaticoduodenal aneurysms is discussed.

Abstract
AIM To review all reported methods of preoperative computed tomography (CT) in one patient cohort and to identify which were the strongest to predict postoperative pancreatic fistula (POPF) after pancreatoduodenectomy. MATERIALS AND METHODS Consecutive patients undergoing pancreatoduodenectomy were included if they had unenhanced CT images for review. Eighteen variables and two scores were tested. Receiver operator characteristics (ROC) were explored. RESULTS POPF affected 26 of 107 patients (24.3%). Nine variables were significantly related to POPF with pancreatic duct width having the largest area under the ROC curve (AUROC; 0.808, p<0.001). An obese body habitus was associated with POPF with six of nine related variables using data from CT images associated with POPF; of these intra-abdominal wall thickness yielded the largest AUROC (0.713, p=0.001). This corresponded to the finding that body mass index (BMI) was related to POPF (AUROC 0.705, p=0.002). The largest AUROC of all was associated with one of the predictive scores (0.828, p<0.001). Substituting BMI for intra-abdominal wall thickness in this score yielded a non-significant increase to predict POPF (AUROC 0.840, p=0.676). None of the assessments of organ density (in Hounsfield Units) were associated with POPF. CONCLUSION Data from preoperative CT imaging provides valuable information regarding a patient's risk of POPF. Obesity as assessed by CT images strongly relates to POPF, but the largest single risk factor for POPF is a narrow pancreatic duct.

Abstract
CONTEXT Carcinoid heart disease (NET-CHD) is associated with the development of symptom-limited exercise capacity and high rates of morbidity and mortality. OBJECTIVE This study sought to determine the survival, cardiac function, and functional class following surgery. DESIGN AND SETTING, AND PATIENTS This was a retrospective observational cohort study between 2005 and 2015 at a European Centre of Excellence for Neuroendocrine Tumours, Queen Elizabeth Hospital Birmingham. England consisting of 62 consecutive patients referred to the NET-Cardiology Service. INTERVENTIONS Subjects were assessed at referral using transthoracic echocardiography (with saline contrast) and transesophageal echocardiography, and 77% with confirmed NET-CHD underwent cardiovascular magnetic resonance imaging. Symptomatic patients with concomitant severe valvular dysfunction were referred for surgery with stable NET disease. MAIN OUTCOME MEASURE Survival of patients with proven NET-CHD following medical and surgical treatments was measure. RESULTS In total, 47/62 patients were diagnosed with NET-CHD. Thirty-two patients (68%) underwent surgery with bioprosthetic valve replacements in all subjects; tricuspid, n = 31; pulmonary, n = 30; mitral, n = 3; and aortic, n = 3. Four patients underwent concomitant coronary artery bypass grafting. There were 4 (13%) early post-operative deaths. One- and 2-y survival rates after surgery were 75 and 69% compared with 45 and 15% in un-operated patients. Post-operatively, functional class was improved (pre-New York Heart Association Classification [NYHA], 2.6 [0.5] vs post-NYHA, 1.7 [1.1]), P < .05, right-ventricular (RV) size was reduced (136 ml/m(2) [25] vs 71 ml/m(2) [7]; P < .01) with preserved RV ejection fraction (61% ± 9 vs 55% ± 10; P = .26). CONCLUSION Valve surgery improved functional class and resulted in RV reverse remodelling with improved survival rates at 2 y compared with those not proceeding to operation. These data highlight the importance of close collaboration between NET clinicians, cardiology, and cardiothoracic surgery teams. Early referral can improve functional capacity but more research is needed to define the selection of appropriate candidates and randomized data are needed to define the effect of surgery on prognosis.

Abstract
There has been a growing role for both diagnostic and interventional radiology (IR) in all types of trauma affecting different areas of the body, with imaging becoming an integral part of the multidisciplinary approach to modern trauma care. This article is intended to assess the role of radiology in peripheral trauma and highlight some of the indications, contraindications and treatment options available. It will also touch upon other associated problems encountered by the trauma patient in particular the increased risk of thromboembolic disease. We review some of the common peripheral vascular injuries in our experience in a large trauma hospital.

Abstract
AIM To assess accuracy of CT colonography (CTC) in identifying synchronous lesions in patients with colorectal carcinoma. METHODS This study included 174 consecutive patients undergoing CTC as part of staging or primary investigation where a colorectal cancer was diagnosed between 2004 and 2007. Prone unenhanced and portal phase enhanced supine series with air or CO(2) distension were acquired using 4- or 16-slice CT (Toshiba) and read by 2D +/- 3D formats. Synchronous lesions were classified according to American College of Radiology's (ACR) polyp classification. Segmental gold standard was flexible sigmoidoscopy/colonoscopy within 1 year and/or histology of colonic resection supplemented by follow-up. Nine patients without gold standard were excluded. Sensitivity, specificity and accuracy were calculated on a per polyp, per patient and per segment basis and discrepancies analysed. RESULTS Direct comparable data were available for 764/990 colonic segments from 165 patients. Of 41 (C2-C4) synchronous lesions on "gold standard", 33 were correctly identified on virtual colonoscopy (VC), overall per polyp sensitivity was 80.5%, with detection rates of 20/24 C3 (83.3%) and 3/3 C4 (100%) with per patient and per segment specificity of 95.4% and 99.2%, respectively. CONCLUSION CTC is an accurate technique to assess for significant synchronous lesions in patients with colorectal cancer and is applicable for total pre-operative colonic visualisation.

Abstract
INTRODUCTION Although there has been many studies quoting ENT and rhinology complications, there have been none looking at the complication rates of one department with a single specialist rhinologist over a 5-year period. PATIENTS AND METHODS Over a 5-year period between 1998 and 2002, the number of operative procedures undertaken in the ENT department in a busy district general hospital was collected in a prospective manner. RESULTS A total of 10,768 ENT procedures were undertaken in the department which comprised four consultants and associated junior staff (SpRs/SASs/SHOs); 2507 of these procedures were rhinology cases. There were 39 recorded complications following nasal surgery, giving an overall rhinology complication rate of 1.56%. This included 12 postoperative nose bleeds (0.48%), 5 cases of infection following septal surgery (0.56%), 7 cases of septal perforation (0.75%) and various minor functional endoscopic sinus surgery (FESS) complications (2.17%). These figures are either below or within the quoted literature rates. There were no major complications or deaths recorded following nasal surgery. CONCLUSIONS These results compare favourably with those of other studies.

Abstract
Embryological abnormalities of the branchial apparatus present an interesting diagnostic and surgical challenge. Thymic cysts are a rare form of branchial apparatus anomaly, resulting from abnormal development of the third pharyngeal pouch. We present two cases of a thymic cyst coexisting with a non recurrent inferior laryngeal nerve (NRILN), two anomalies that to our knowledge have not been associated previously. A possible embryological explication for this double abnormality is discussed, while the clinical implications of this association are presented.

Abstract
OBJECTIVE To determine the need for suction drainage after elective thyroid and parathyroid surgery. DESIGN Randomised controlled trial. SETTING University teaching hospital. PARTICIPANTS Patients requiring elective thyroid or parathyroid surgery were recruited and informed consent was obtained (n = 100). Before wound closure, patients were randomised into either group A (to remain without suction drainage) or group B (to receive suction drainage). Excluded patients were those requiring associated neck dissection and those with bleeding diatheses, all of whom would necessarily require drainage in our unit. MAIN OUTCOME MEASURES Primary - ultrasound evaluation of any collection in the thyroid bed, performed 1-day postoperatively. Secondary - postoperative complications; length of in-patient stay. RESULTS One hundred patients completed the study, and groups A and B comprised 50 patients each. Patients in each group exhibited a mean age of 49 years, and a male to female ratio of 1 : 9. Both groups were also well-matched regarding type of operation, size of tumour and histopathological diagnosis. Modal and median postoperative neck collection volume on ultrasound examination was 0 and 0 cm(3) respectively (range 0-16 cm(3)) in group A and was 0 and 0 cm(3) (range 0-70 cm(3)) in group B. This difference was not statistically significant, but three patients with a haematoma were all in the suction drainage group. Difference in complication rates between groups was also not statistically significant. Modal and median length of in-patient stay was 2 and 2 days respectively (range 2-3 days) in group A and 3 and 3 days (range 2-4 days) in group B, and this difference was statistically significant (P = 0.0006). CONCLUSION Routine suction drainage after uncomplicated elective thyroid and parathyroid surgery appears unnecessary, and prolongs in-patient stay.

Abstract
Schwannomas are benign slow growing solitary tumours of nerve sheath origin and can arise from any myelinated nerve. They have been reported to occur in most parts of the body with the highest incidence (25%) in the head and neck region, although tongue base lesions are rare. The tumour is resistant to radiotherapy, and therefore, the treatment of choice is surgery. We present a case of a tongue base schwannoma which was completely extirpated with a carbon dioxide laser via the transoral approach. The patient experienced virtually no morbidity from the use of the laser. Whilst tongue base schwannoma has been documented, we could not find an earlier report in the English literature describing our method of treatment. We conclude that transoral carbon dioxide laser can be added to the surgical armamentarium for the management of other similar cases in the future.
