    Abstract Background: There are evolving data correlating elevated post-hepatic resection portal vein pressure (PVP) with risk of developing post-resection liver failure (PLF) and other complications. As a consequence, modulation of PVP presents a potential strategy to improve outcomes following liver resection (LR). The primary aim of this study was to review the existing evidence regarding the impact of post-resection PVP on clinical outcomes in patients undergoing a LR.
    Methods: Systematic literature searches of electronic databases in accordance with PRISMA were conducted. Changes in PVP and clinical outcomes following liver resection were defined according to the existing literature.
    Results: Ten studies, consisting of 712 patients with a median age 61 (52-68) years, were identified that met the inclusion criteria. Of those, 77% (n = 550) underwent a major LR and 27% (n = 195) of patients had cirrhosis. Following LR, the median (range) PVP increased from 11.4 mmHg (median baseline, range 7.3-16.4) to 15.9 mmHg (7.9-19). The overall median incidence of PLF was 19%. Six of the ten studies found an elevated PVP after LR predicted PLF. One study found elevated PVP after LR predicted mortality after LR.
    Conclusion: Elevated PVP following hepatic resection was associated with increased rates of PLF. It was not possible to define a specific threshold PVP for predicting PLF. Modulation of PVP therefore presents a potential strategy to mitigate the incidence of LR. Future studies should standardize on reporting liver remnant and haemodynamics to better characterize clinical outcomes following LR.

    Abstract Background: This population-based cohort study aimed to determine postoperative outcomes after emergency and elective cholecystectomy in patients with cirrhosis.
    Methods: Linked electronic healthcare data from England were used to identify all patients undergoing cholecystectomy between January 2000 and December 2017. Length of stay (LOS), re-admission, case fatality and the odds ratio of 90-day mortality were calculated for patients with and without cirrhosis, adjusting for age, sex and co-morbidity using logistic regression.
    Results: Of the total 69,141 eligible patients who underwent a cholecystectomy, 511 (0.74%) had cirrhosis. In patients without cirrhosis 86.55% underwent a laparoscopic procedure compared with 57.53% in patients with cirrhosis (p < 0.0001). LOS was longer in those with cirrhosis (3 IQR 1-8 vs 1 IQR 1-3 days,p < 0.0001). 90-day re-admission was greater in patients with cirrhosis, 36.79% compared with 14.95% in those without cirrhosis. 90-day case fatality after elective cholecystectomy in patients with and without cirrhosis was 2.79% and 0.43%; and 12.82% and 2.39% following emergency cholecystectomy. This equated to a 3-fold (OR 3.22, IQR 1.72-6.02) and a 4-fold (OR 4.52, IQR 2.46-8.33) increased odds of death at 90-days following elective and emergency cholecystectomy after adjusting for confounders.
    Conclusion: Patients with cirrhosis undergoing cholecystectomy have an increased 90-day risk of postoperative mortality, which is significantly worse after emergency procedures.

    Abstract Introduction: The mortality risk after appendicectomy in patients with liver cirrhosis is predicted to be higher than in the general population given the associated risk of perioperative bleeding, infections and liver decompensation. This population-based cohort study aimed to determine the 90-day mortality risk following emergency appendicectomy in patients with cirrhosis.
    Methods: Adult patients undergoing emergency appendicectomy in England between January 2001 and December 2018 were identified from two linked primary and secondary electronic healthcare databases, the clinical practice research datalink and hospital episode statistics data. Length of stay, re-admission, case fatality and the odds ratio of 90-day mortality were calculated for patients with and without cirrhosis, adjusting for age, sex and co-morbidity using logistic regression.
    Results: A total of 40,353 patients underwent appendicectomy and of these 75 (0.19%) had cirrhosis. Patients with cirrhosis were more likely to be older (p < 0.0001) and have comorbidities (p < 0.0001). Proportionally, more patients with cirrhosis underwent an open appendicectomy (76%) compared with 64% of those without cirrhosis (p = 0.03). The 90-day case fatality rate was 6.67% in patients with cirrhosis compared with 0.56% in patients without cirrhosis. Patients with cirrhosis had longer hospital length of stay (4 (IQR 3-9) days versus 3 (IQR 2-4) days and higher readmission rates at 90 days (20% vs 11%, p = 0.019). Most importantly, their odds of death at 90 days were 3 times higher than patients without cirrhosis, adjusted odds ratio 3.75 (95% CI 1.35-10.49).
    Conclusion: Patients with cirrhosis have a threefold increased odds of 90-day mortality after emergency appendicectomy compared to those without cirrhosis.

    Abstract Background: Patients with cirrhosis undergoing colectomy have a higher risk of postoperative mortality, but contemporary estimates are lacking and data on associated risk and longer term outcomes are limited. This study aimed to quantify the risk of mortality following colectomy by urgency of surgery and stage of cirrhosis.
    Data sources: Linked primary and secondary-care electronic healthcare data from England were used to identify all patients undergoing colectomy from January 2001 to December 2017. These patients were classified by the absence or presence of cirrhosis and severity. Case fatality rates at 90 days and 1 year were calculated, and cox regression was used to estimate the hazard ratio of postoperative mortality controlling for age, gender and co-morbidity.
    Results: Of the total, 36,380 patients undergoing colectomy, 248 (0.7%) had liver cirrhosis, and 70% of those had compensated cirrhosis. Following elective colectomy, 90-day case fatality was 4% in those without cirrhosis, 7% in compensated cirrhosis and 10% in decompensated cirrhosis. Following emergency colectomy, 90-day case fatality was higher; it was 16% in those without cirrhosis, 35% in compensated cirrhosis and 41% in decompensated cirrhosis. This corresponded to an adjusted 2.57 fold (95% CI 1.75-3.76) and 3.43 fold (95% CI 2.02-5.83) increased mortality risk in those with compensated and decompensated cirrhosis, respectively. This higher case fatality in patients with cirrhosis persisted at 1 year.
    Conclusion: Patients with cirrhosis undergoing emergency colectomy have a higher mortality risk than those undergoing elective colectomy both at 90 days and 1 year. The greatest mortality risk at 90 days was in those with decompensation undergoing emergency surgery.

    Abstract Introduction: Prehabilitation aims to improve fitness and outcomes of patients undergoing major surgery. This systematic review aimed to appraise current available evidence regarding the role of prehabilitation in patients undergoing oncological pancreatic resection.
    Methods: A systematic literature search of PUBMED, MEDLINE, EMBASE databases identified articles describing prehabilitation programmes before pancreatic resection for malignancy. Data collected included timing of prehabilitation, programme type, duration, adherence and post-operative outcome reporting.
    Results: Six studies, including 193 patients were included in the final analysis. Three studies included patients undergoing neoadjuvant therapy followed by resection and 3 studies included patients undergoing upfront resection. Time from diagnosis to surgery ranged between 2 and 22 weeks across all studies. Two studies reported a professionally supervised exercise programme, and four described unsupervised programmes. Exercise programmes varied from 5 days to 6 months in duration. Adherence to exercise programmes was better with supervised programmes (99% reaching weekly activity goal vs 85%) and patients not undergoing neoadjuvant therapy (90% reaching weekly activity goal vs 82%). All studies reported improvement in muscle mass or markers of muscle function following prehabilitation. Two studies reported the impact of Prehabilitation on postoperative outcomes and Prehabilitation was associated with lower delayed gastric emptying and a shorter hospital stay with no impact on other postoperative outcomes.
    Conclusion: Early evidence demonstrates that Prehabilitation programmes may improve postoperative outcomes following pancreatic surgery. However current Prehabilitaton programmes for patients undergoing pancreatic resection report diverse exercise regimens with no consensus regarding timing or length of Prehabilitation, warranting a need for standardisation of Prehabilitation programmes in pancreatic surgery.

    Abstract Introduction: Symptomatic umbilical hernias are a common cause of morbidity and mortality in patients with cirrhosis and end-stage liver disease (ESLD). This study set out to characterise the factors predicting outcome following repair of symptomatic umbilical hernias in ESLD at a single institution.
    Methods: A retrospective review was performed of all patients with ESLD who underwent repair of a symptomatic umbilical hernia between 1998 and 2020. Overall survival was predicted using the Kaplan-Meier method. Logistic regression was used to determine predictors of decompensation and 30-day, 90-day and 1-year mortality.
    Results: One-hundred-and-eight patients with ESLD underwent umbilical hernia repair (emergency n = 78, 72.2%). Transjugular shunting was performed in 29 patients (26.9%). Decompensation occurred in 44 patients (40.7%) and was predicted by emergency surgery (OR, 13.29; P = 0.001). Length of stay was shorter in elective patients compared to emergency patients (3-days vs. 7-days; P = 0.003). Thirty-day, 90-day and 1-year survival was 95.2, 93.2 and 85.4%, respectively. Model for ESLD score >15 predicted 90-day mortality (OR, 18.48; P = 0.030) and hyponatraemia predicted 1-year mortality (OR, 5.31; P = 0.047). Transjugular shunting predicted survival at 1 year (OR, 0.15; P = 0.038).
    Conclusions: Repair of symptomatic umbilical hernias in patients with ESLD can be undertaken with acceptable outcomes in a specialist centre, however, this remains a high-risk intervention. Patients undergoing emergency repair are more likely to decompensate postoperatively, develop wound-related problems and have a longer length of stay. Transjugular shunting may confer a benefit to survival, but further prospective trials are warranted.

    Abstract Background: The risk factors for surgical site infection (SSI) after HPB surgery are poorly defined. This meta-analysis aimed to quantify the SSI rates and risk factors for SSI after pancreas and liver resection.
    Methods: The PUBMED, MEDLINE and EMBASE databases were systematically searched using the PRISMA framework. The primary outcome measure was pooled SSI rates. The secondary outcome measure was risk factor profile determination for SSI.
    Results: The overall rate of SSI after pancreatic and liver resection was 25.1 and 10.4%, respectively (p < 0.001). 32% of pancreaticoduodenectomies developed SSI vs 23% after distal pancreatectomy (p < 0.001). The rate of incisional SSI in the pancreatic group was 9% and organ/space SSI 16.5%. Biliary resection during liver surgery was a risk factor for SSI (25.0 vs 15.7%, p = 0.002). After liver resection, the incisional SSI rate was 7.6% and the organ space SSI rate was 10.2%. Pancreas-specific SSI risk factors were pre-operative biliary drainage (p < 0.001), chemotherapy (p < 0.001) and radiotherapy (p = 0.007). Liver-specific SSI risk factors were smoking (p = 0.046), low albumin (p < 0.001) and significant blood loss (p < 0.001). The rate of organ/space SSI in patients with POPF was 47.7% and in patients without POPF 7.3% (p < 0.001). Organ/space SSI rate was 43% in patients with bile leak and 10% in those without (p < 0.001).
    Conclusions: The risk factors for SSI following pancreatic and liver resections are distinct from each other, with higher SSI rates after pancreatic resection. Pancreaticoduodenectomy has increased risk of SSI compared to distal pancreatectomy. Similarly, biliary resections during liver surgery increase the rates of SSI.
