Pancreatic cancer tends to have an ominous character, partly cause disease is a) advanced age, so even in resectable cases many patients are unfit for surgery and b) most cancers are borderline resecable, irresectable or metastatic. (80% of the pancreatic cancers are diagnosed in advanced stages)

Even in patient with surgical resection, the 5-year survival is quoted as 27%

A recent review showed that 5-year survival is 30% in Ia (T1 N0 M0- single 2cm or less panc mass)  dropping to 11.8% in Ib ( T2 N0 M0, this is single mass 2-4cm). When putting all the stages together, the 5 year survival is only 5%.

The best possible outcome would theorically be in an early cancer, 2cm or less (T1), found either incidentally (or if it gives symptoms very early), resectable (non conctacting vessels and not involving other anatomical structures, as well as surgically accesible)  and in a fit patient amenable for surgery.

Many chronic pancreatitis causing biliary stricture are asymptomatic or associate minimal changes in liver blood tests particularly ALP. In order to call cholestasis we have to see an increase in of usually >3 times ULN of alkaline phosphate (this is about >350-400 U/L)  As long as it does not cause significant cholestasis or cholangitis, there is no indication of biliary draining. IF they associate biliary stones , episodes of repeating infection or biliary pain (his pain seems more due to chronic pancreatitis) then it is justifed to drain the biliary tree.

Despite some increases in ALP, Conservative management with close monitoring is still adequate in this case, as well as recommend complete alcohol abstinence. If his bloods worsen or the bile dilation progresses during the next months, ERCP could be dicussed in a multidisciplinary meeting (risk of stenosis progression and cholestasis vs risk of ERCP adverse events)

- Gastric lesions. Even though ESGE guidelines do not specifically mention EUS in the flowchart staging, the reality is that EUS can clarify lymph nodes and the layer invasion, so realistically can be  useful for all the answers mentioned.

Hb needs to be kept 7-8g/dl at least,  and a target of >9-10g/dl  if significant cardiovascular disease.  Andenaxet is recommended if life threatening or uncontrolled bleeding, like this case which is responding only partially to resucitation with fluids and continues to pass blood, so it could be prescribed.  If not available, 4-F PCC can be used instead.  Urgent sigmoidoscopy in general has no role and it would likely be useless without an adequate bowel preparation as we would expect to have very poor visibility due to stool and blood remains.

Unprepped colonoscopy or any form of sigmoidoscopy is NOT recommended in acute lower GI Bleeding unless very clear that the source is known to be anorectal or very distal colon (see American Guidelines) BSG guidelines also recommneds Colonoscopy as  inpatient with adequate bowel preparation, not urgently but  ideally after stabilising the patient.

If after resucitation and transfusion the patient remains unstable, then a joined plan with intensivist and surgical colleagues should be made (i.e, Interventional radiology, vs quick preparation with movicol, vs enema and salvage lower endoscopy, vs surgical approach)
