    Abstract Tumour heterogeneity is a common phenomenon in neuroendocrine neoplasms (NENs) and a significant cause of treatment failure and disease progression. Genetic and epigenetic instability, along with proliferation of cancer stem cells and alterations in the tumour microenvironment, manifest as intra-tumoural variability in tumour biology in primary tumours and metastases. This may change over time, especially under selective pressure during treatment. The gastroenteropancreatic (GEP) tract is the most common site for NENs, and their diagnosis and treatment depends on the specific characteristics of the disease, in particular proliferation activity, expression of somatostatin receptors and grading. Somatostatin receptor expression has a major role in the diagnosis and treatment of GEP-NENs, while Ki-67 is also a valuable prognostic marker. Intra- and inter-tumour heterogeneity in GEP-NENS, however, may lead to inaccurate assessment of the disease and affect the reliability of the available diagnostic, prognostic and predictive tests. In this review, we summarise the current available evidence of the impact of tumour heterogeneity on tumour diagnosis and treatment of GEP-NENs. Understanding and accurately measuring tumour heterogeneity could better inform clinical decision making in NENs.

    Abstract The pandemic of coronavirus disease 2019 (COVID-19) changed the surgical everyday practice overnight. Currently, the first articles reporting outcomes of liver transplant recipients infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are published. The aim of the present study was to summarise the existing evidence of impact of COVID-19 global pandemic on liver transplant recipients. Electronic databases were searched in accordance with Preferred Reporting Items in Systematic Reviews and Meta-Analyses (PRISMA). Five studies were selected from a pool of 12 studies with a total of 854 liver transplant recipients of whom 700 were children and the rest 154 were adults. The present evidence, based on case reports and series demonstrated lower mortality in liver transplant recipients compared to general population.

    Abstract Background: The management of radiologically suspected gallbladder cancers (GBC) that lack definitive radiological features usually involves performing a first-stage routine laparoscopic cholecystectomy, followed by an open second-stage liver resection (segments IVB and V) and hilar lymphadenectomy (extended cholecystectomy) if subsequent formal histology confirms a malignancy. Performing a cholecystectomy with an intraoperative frozen section to guide the need for conversion to an extended cholecystectomy as a single-stage procedure has multiple benefits compared to a two-stage approach. However, the safety and efficacy of this approach have not yet been evaluated in a tertiary setting.
    Methods: A retrospective cohort study was performed using a database of all consecutive patients with suspected GBC who had been referred to our tertiary unit. Following routine cholecystectomy, depending on the operative findings, the gallbladder specimen was removed and sent for frozen-section analysis. If malignancy was confirmed, the depth of tumour invasion was evaluated, followed by simultaneous extended cholecystectomy, when appropriate. The sensitivity and specificity of frozen section analysis for the diagnosis of GBC were measured using formal histopathology as a reference standard.
    Results: A total of 37 consecutive cholecystectomies were performed. In nine cases, GBC was confirmed by intraoperative frozen section analysis, three of which had standard cholecystectomy only as their frozen section showed adenocarcinoma to be T1a or below (n=2) or were undetermined (n=1). In the remaining six cases, malignant invasion beyond the muscularis propria (T1b or above) was confirmed; thus, a synchronous extended cholecystectomy was performed. The sensitivity (95% CI 66.4%-100%) and specificity (95% CI 87.7%-100%) for identifying GBC using frozen section analysis were both 100%. The net cost of the single-stage pathway in comparison to the two-stage pathway resulted in overall savings of £3894.
    Conclusion: Intraoperative frozen section analysis is a reliable tool for guiding the use of a safe, single-stage approach for the management of GBC in radiologically equivocal cases. In addition to its lower costs compared to a conventional two-stage procedure, intraoperative analysis also affords the benefit of a single hospital admission and single administration of general anaesthesia, thus greatly enhancing the patient's experience and relieving the burden on waiting lists.

    Abstract Background: Laparoscopic pancreatectomy is currently a widely used approach for benign and malignant lesions of the pancreas.
    Aims: This study aimed to describe how to perform a laparoscopic distal pancreatectomy using The Clockwise Technique.
    Methods: An 18-year-old female patient presented with a well-defined tumor in the pancreatic body with 4 cm in diameter that suggested a diagnosis of solid pseudopapillary tumor (Frantz's tumor). The patient was recommended for laparoscopic distal pancreatectomy by using The Clockwise Technique.
    Results: The clockwise, caudal-to-cephalic approach appears to have other significant technical advantages that facilitate the performance of the procedure.
    Conclusions: A laparoscopic distal pancreatectomy performed using The Clockwise Technique provides satisfactory outcomes.

    Abstract Background: This study analysed whether local anaesthetic wound catheter infiltration (LA-WCI) as an adjunct to intravenous patient-controlled analgesia (IV-PCA) provides superior outcomes compared to IV-PCA alone following liver resection.
    Methods: A systematic review and meta-analysis was conducted for randomised control trials (RCTs) comparing LA-WCI with IV-PCA(LA-WCI group) versus IV-PCA alone (IV-PCA group). PubMed and the Cochrane Library were searched for relevant articles.
    Results: Six RCTs with a total of 440 patients were included. Opioid use in the initial 48 h was less in the LA-WCI group [MD -21.27 mg (-39.39,-3.15), p = 0.02]. Pain scores were lower in the LA-WCI group at rest at POD0 (post-operative day 0)6-8 h (p = 0.0009), POD1AM(p = 0.01), POD1PM(p = 0.02) and POD2 (p = 0.0006), and exertion at POD0 0-2 h (p = 0.05), POD1AM(p = 0.03), POD1PM(p = 0.03), POD2 (p = 0.03) and POD3 (p = 0.01). LA-WCI group had reduced length of hospital stay [MD -1.32 days (-2.23,-0.40),p = 0.005], time to ambulation [MD -5.94 h (-8.47,-3.42),p = 0.00001] and incidence of nausea and vomiting (PONV) [OR 0.17 (0.07,0.43),p = 0.0002]. No differences were observed in length of intensive care unit (ICU) stay or incidence of surgical site infections.
    Discussion: LA-WCI as an adjunct to opiate IV-PCA post-hepatectomy reduces opioid use, pain scores at multiple time points at rest and exertion, length of hospital stay, time to ambulation and PONV. However, LA-WCI use does not alter length of ICU stay or incidence of wound infection.

    Abstract Aim: Locally advanced intestinal neoplasms including colon cancer may require radical en bloc pancreaticoduodenectomy and right hemicolectomy (PD-RC) to achieve curative, margin-negative resection, but the safety and benefit of this uncommon procedure has not been established. The Association of Coloproctology of Great Britain and Ireland IMPACT initiative has also highlighted a lack of awareness about current services available within the UK for patients with advanced colorectal cancer and concerns about low-volume centres managing complex cases. Thus, we aimed to review the feasibility, safety and long-term outcomes of this procedure at a single high-volume hepatopancreaticobiliary surgery unit in the UK.
    Method: A retrospective cohort study was performed using a database of all consecutive patients with intestinal cancer who had been referred to our regional advanced multidisciplinary team and undergone PD-RC in a 7-year period (2013-2020). Clinico-pathological and outcome data were reviewed.
    Results: Ten patients (mean age 54 ± 13, 8/10 men) were identified. Final histology revealed the primary tumour sites were colon (n = 7) and duodenum (n = 3). R0 resection was achieved in all cases. The major complication rate (Clavien-Dindo ≥ 3) was 10% (1/10) with no deaths within 90 days of surgery. The Kaplan-Meier estimated 5-year overall survival was 83.3% (95% CI 58.3%-100%). Univariate survival analysis identified perineural invasion and extra-colonic origin as predictors of poor survival (log-rank P < 0.05).
    Conclusion: En bloc PD-RC for locally advanced intestinal cancer can be performed safely with a high proportion of margin-negative resections and resultant long-term survival in carefully selected patients.

    Abstract Background: Pancreaticoduodenectomy is associated with high rates of morbidity. This combined with the psychological burden of cancer, may impact on a patient's quality of life (QoL), which can be measured by using patient-reported outcomes (PRO).
    Objective: To perform a systematic review to evaluate the measurement of PRO after pancreaticoduodenectomy for cancer.
    Methods: 7 different databases were searched using 2 groups of search terms, one relating to pancreaticoduodenectomy, and one to PRO. Three authors screened the search results independently in a systematic manner based on predefined inclusion and exclusion criteria.
    Results: 27 studies, with 2173 eligible patients were included in the final analysis. Most of the included studies used validated instruments. The European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire was most popular and used in 12 studies. The methodology of all included studies was also scrutinised. 12 studies were deemed to have high quality methodology according to pre-defined criteria.
    Conclusion: The instruments and methods used to measure PRO are variable. The quality of PRO within the available literature has improved over time, as has the number of studies measuring PRO. PRO should be measured with uniformity in future trials so that patients can be provided with more comprehensive information regarding post-operative recovery and QoL during the shared decision-making process preoperatively.

    Abstract Background-Objectives: It has been reported, that high posthepatectomy portal vein pressure (PVP) has deleterious effect on the liver parenchyma and causes posthepatectomy liver failure (PHLF) and increased 90-day mortality. Terlipressin, is widely used to mitigate the effects of portal hyper-tension. Randomised clinical trials (RCTs) demonstrated encouraging results of use of terlipressin for modulation of increased posthepatectomy PVP. The aim of the present study was to evaluate the effectiveness of the pharmacological modulation of the increased posthepatectomy PVP after major hepatectomy.
