Making sense of the liver volume/function relationship in health and disease will lead to safer liver surgery
Here is my highlight from the december issue of HPB
Radioembolization is still searching for its precise niche in the armoury of treatments for colorectal liver metastases. The majority of protocols advise its use in patients who have non-resectable and chemotherapy-resistant liver metastases with some requiring failure of first line chemotherapy and some second line chemotherapy. Guidance on its use in patients with extrahepatic sites of disease is also somewhat variable. Economic considerations influence patient selection in a number of healthcare models in addition to outcome data.
In this edition of HPB, Tohme and colleagues from the University of Pittsburgh explore outcomes of older patients treated with radioembolization. They have reported outcomes of more than 100 patients older or younger than 70 years treated with one or more episodes of radioembolization for non-resectable liver metastases which have proved resistant to one or two chemotherapy regimens. Fatigue is a frequently reported complicating symptom of radioembolization. It might be considered that elderly patients have less physical reserve. However, the Pittsburgh group found no difference in either frequency or severity of fatigue in treated patients based on age. Other side effect profiles were also similar suggesting that this treatment modality is well tolerated by the elderly. In terms of patient survival, again there was no difference in outcome based on patient age. The major determinant of poor outcome appeared to be the presence of extrahepatic disease but this was the same irrespective of age.
This article provides evidence that radioembolization is effective and reasonably well tolerated in patients with colorectal liver metastases and should be considered in motivated patients regardless of age.

Here is my highlight from the Journal HPB for November which relates to an analysis of damage control surgery for major pancreas trauma. This is a must read paper on the very difficult problem of major pancreas trauma from South Africa.
The pancreas is usually considered to be well protected however, it’s anatomical relationships mean that when the head of the gland is injured there are frequently severe associated injuries to vasculature or important structures such as the bile duct and duodenum. Major trauma to the pancreatic head therefore, represents a life-threatening situation for the patient and a complex management issue for the surgeon.
In this issue of HPB, Krige and colleagues from Cape Town, South Africa present a wealth of experience of pancreatic trauma. The article refers to a cohort of more than 400 pancreatic trauma cases with focus on 19 with the most severe grade 5 injuries. The mechanism of injury included penetrating trauma from gunshot and stab wounds as well as blunt trauma from road traffic accidents. Approaches to management were tailored to the individual patient needs. A number of these cases were associated with major haemorrhage from vena cava or portal vein injuries which required control prior to dealing with pancreatic injury itself.
The concept of damage control surgery originated in South Africa and this series includes a number of patients who had two or more stage procedures after initial damage control of the pancreatic injury. This measured approach seems entirely sensible given the potential difficulties of reconstruction after pancreaticoduodenectomy in an unstable patient. This approach is a good learning point and must have contributed to the excellent survival rate of 84% in these patients at the extreme end of the pancreatic trauma scale.

Donor age is no bar to successful liver transplantation unless the recipient has untreated hepatitis C virus disease
Here is my highlight from the current issue of HPB.
The disparity between supply and demand of donor livers for transplantation remains an ever-present challenge and drives the use of extended criteria donor organs. Donor age is one criterion that has been moving steadily upwards but changes have often been based on anecdote rather than evidence. In addition much of what we know about using older donor livers relates to short-term outcomes but there is clearly interest in how an already old liver will do in a recipient who may be expected to have a long post-transplant life expectancy. In this edition of HPB, Chedid et al. explore the Mayo Clinic experience of transplanting livers from 70 and 80 year old cadaveric donors. In their experience, 107 donor livers (14 % of the total series) were from this older population. Fewer livers from older donors were transplanted into recipients with hepatitis C, which concurs with their institutional policy based on evidence of better outcomes in hepatitis C recipients for liver transplantation from younger donors. They found no difference in graft or patient survival for the overall population based on donor age being greater or less than 70 years. In the hepatitis C recipients, there was a clear disadvantage both in terms of patient and graft survival to patients receiving a graft from an over 70 years donor. Although there is undoubtedly a need for careful selection of livers in the older populations with the avoidance of steatosis, there is clear evidence of benefit from using older livers from brainstem dead heart-beating donors. The introduction of new effective antiviral therapies for Hepatitis C may negate the observed adverse outcome association of transplanting older livers into hepatitis C recipients. Older individuals in society should be afforded the possibility of donating their livers, where appropriate, as it is clear that recipients will benefit.

Here is my highlight from the July issue of HPB.
Good post-operative pain control is a central part of recovery after surgery. ERAS programmes, in particular, have heavily promoted the use of epidural analgesia for abdominal surgery. This probably owes something to the roots of ERAS in colorectal surgery however many of the studies on which these recommendations were made are outdated and relate to very different operative procedures. Epidural analgesia is known to offer good dynamic and static pain control but does have drawbacks in terms of hypotension, immobility and rare but life threatening complications of epidural abscess or epidural haematoma. The liver surgery group in Basingstoke have been one of the major centres pioneering local anaesthetic wound catheter infiltration of upper abdominal wounds combined with patient controlled opiates as an alternative to epidural analgesia. In this edition of HPB, Wong-Lu-Hing and colleagues report the Basingstoke experience of wound catheter analgesia after liver resection in a retrospective comparative cohort analysis including a small group of contemporaneous patients receiving epidural analgesia (analgesic selection based on surgeon preference). Although not a randomized trial they clearly show some important benefits from wound catheter analgesia. These were equivalency of analgesia combined with reduced overall complication rates, reduced opiate requirement and a shorter length of stay compared with patients receiving epidural analgesia. Further refinements to local anaesthetic protocols such as additional transversus abdominis plane blocks may improve the effectiveness of this analgesic approach and it seems certain that this will remain an effective alternative if not a preferred alternative to epidural analgesia in liver surgery.

Here is my editorial highlight from the June edition of HPB the official journal of the IHPBA, A-HPBA and EA-HPBA
Living organ donation is unusual in medical practice because for the donor there is a significant health risk incurred through donation which is only offset by a sense of well being from helping another human who is in clinical need. In his contemporary analysis of Darwinist theory ‘The Selfish Gene’, Richard Dawkins explains altruism in terms of protecting lines of inheritance and in this analysis he questions the illogicality of altruistic acts outside of this framework.
This issue of HPB contains an analysis by Molinari and colleagues of the drivers for living liver donors to donate. The paper acknowledges the balance between risk and benefit and there is a several log order increased risk of serious harm or death to otherwise healthy individuals compared with for example living kidney donation. Molinari et al. did find that altruism wasn’t given completely freely. Apart from the obvious need for a biological or close emotional relationship between donor and recipient, donors had an expectation of reasonable prospects of survival for the recipient at one and 3 years. Donors were likely to donate if there was an expectation that the recipient would have a protracted wait for a cadaveric graft.
Interestingly donors were prepared to accept a greater level of risk than clinicians. This study provides an important insight into the decision-making processes of potential liver donors. The authors conclude that living donors are ‘risk takers’, while this may be true, the risks are calculated and the donors in this study seemed well equipped to make the decisions underpinning the risk.
Based on the following original article in the June issue of HPB
