RÉSUMÉ
We present a case of 64-year-old US veteran who developed recurrent hepatic encephalopathy (HE) following transjugular intrahepatic portasystemic shunt (TIPSS) procedure. The patient had a history of metabolic syndrome and cirrhosis due to non-alcoholic steatohepatitis. He had undergone sleeve gastrectomy 1 year earlier with preoperative TIPSS placement. He developed recurrent symptoms of HE despite optimising his medications, resulting in poor quality of life and multiple hospitalisations. A liver Doppler ultrasound and CT scan of the abdomen was obtained which showed a patent TIPSS and a prominent shunt between the splenic vein and left renal vein via the left gonadal vein. This was treated with reduction of TIPSS, by placement of a covered stent in an hourglass configuration within the existing TIPSS stent and simultaneous embolisation of the splenorenal shunt by interventional radiology. The patient had complete resolution of symptoms following the procedure without any recurrence of HE.

A 57-year-old man underwent emergency laparoscopic loop colostomy for acute recto-sigmoid obstruction. He was hospitalised 2 months previously, at another facility for diabetic ketoacidosis (DKA) and hyperkalaemia. He had no gastrointestinal symptoms prior to the hospitalisation. Both surgical exploration and intraoperative sigmoidoscopy showed ulcerations of sigmoid colon and proximal rectum with a pinhole stricture in mid-rectum. After ruling out all aetiologies, and due to persistence of the colonic ulcerations on a follow-up colonoscopy, a diagnosis of Crohn's colitis was made, and the patient was started on infliximab and 6-mercaptopurine (6-MP). Six months later, on rereview of all the biopsies, it was noted that a key element of presence of crystals suggestive of Kayexalate on the initial colorectal biopsies was missed. It was later found out that the patient had received rectal Kayexalate for treatment of DKA at the other facility. Hence, infliximab and 6-MP were both discontinued. All the colonoscopies, following the discontinuation of the medications, showed complete resolution of colitis but persistence of the mid-rectum stricture. This was treated with a fully covered metal stent for 12 weeks with only partial improvement of the stricture. He was hence referred for ultra-low anterior resection of rectum and take down of colostomy.

Transarterial chemoembolization (TACE) is a therapeutic procedure often performed for hepatocellular carcinoma (HCC). Local complications, though generally uncommon, can arise from arterial ischemia and local cytotoxicity from the chemotherapeutic delivery. We present a case of acute pancreatitis as a rare complication of the TACE procedure along with a review of literature of this uncommon adverse effect.

BACKGROUND: Approximately 15% to 35% of those with chronic hepatitis C (CHC) related cirrhosis will develop hepatocellular cancer (HCC). With this burden increasing across the globe, identification of risk factors for HCC has become imperative. Exposure to Agent Orange has been implicated as a possible risk factor for liver cancer in a study from the Republic of Korea. However, there has been no study in U.S. veterans with CHC and cirrhosis that has evaluated exposure to Agent Orange as a risk factor for HCC. We conducted a retrospective study of U.S. military veterans diagnosed with CHC and cirrhosis over a period of 14 years to evaluate potential risk factors for HCC including exposure to Agent Orange. METHODS: We retrospectively reviewed 390 patients with confirmed CHC-related cirrhosis between 2000 and 2013 and identified patients with HCC. We compared demographic, laboratory, and other clinical characteristics of patients with and without HCC. RESULTS: The mean age of the cohort was 51 years (SD =7.5), with the majority being male (98.5%). Seventy-nine of 390 (20.2%) patients developed HCC, diagnosed on average 8 (SD =4.8) years after diagnosis of CHC. Nearly half (49.4%) were Childs A, 40.5% were Childs B, and 10.1% were Childs C. HCC patients were more likely to be African American than non-HCC patients (40.5% vs. 25.4%, P=0.009) and to be addicted to alcohol (86.1% vs. 74.3%, P=0.027). A trend toward significance was seen in the HCC group for exposure to Agent Orange (16.5% vs. 10.0%, P=0.10) and smoking addiction (88.6% vs. 80.7%, P=0.10). Consequently, race, alcohol addiction, Agent Orange exposure, and smoking addiction were included in the multivariable logistic regression (MLR) analysis. Alcohol addiction [odds ratio (OR) =2.17; 95% confidence interval (CI), 1.07-4.43] and African American race (OR =2.07; 95% CI, 1.22-3.51) were found to be the only two definitive independent risk factors for HCC in our sample. CONCLUSIONS: African American race and alcohol addiction were independent risk factors for HCC development in this U.S. veteran population. There was no significant association between exposure to Agent Orange and HCC, although larger studies are needed in the U.S. military veteran population to evaluate further this toxic herbicide from the Vietnam War era.
