INTRODUCTION: Pancreatic resection leads to loss of functional pancreatic tissue. The study evaluates the glycemic control and factors affecting the glycemic control in long-term survivors after pancreatic resection. MATERIAL AND METHODS: Patients who survived for three months or more after pancreatectomy were selected. Baseline parameters were collected with an interviewer administered questionnaire. All patients had a fasting blood sugar (FBS) and HbA1C. Previous non diabetics had oral glucose tolerance test (OGTT) at one and two hours. There were 49 Whipple procedures and 6 distal pancreatectomies. 20 Whipple procedure patients and 5 distal pancreatectomy patients consented. Sixteen (64%) participants were females. Median age was 47 (15-70) years. Eleven (44%) were previously known diabetic patients. The median Body Mass Index (BMI) was 18.28 kg/m3 (11.36-30.07). The median time since surgery was 16 (3-37) months. There was one (4%) newly diagnosed diabetic patient. Out of non-diabetics, one had more than 200 mg/dl OGTT at 2 hours. Nine diabetics had HbA1c elevation more than 7%. Mean post-surgical FBS in diabetic patients (136.9 mg/dl) were significantly (p<0.05) higher than pre-surgical FBS (109.4 mg/dl). BMI (p=0.006), waist to hip ratio (p=0.039) and percentage of pancreas removed (p=0.002) showed a significant correlation to worsening of post-surgical sugar control. CONCLUSIONS: Pancreatectomy leads to worsening of blood sugar control in known diabetics. New onset diabetes is rare. Close follow-up and strict control is needed in known diabetics with high BMI and high waist to hip ratio.
Post hepatectomy adjuvant trans-arterial chemotherapy- A pilot study
(College of Surgeons of Sri Lanka, 2015) Ekanayake, C.S.; Bandara, L.M.P.M.; Liyanage, C.A.H.; Niriella, M.A.; Dassanayake, A.S.; Siriwardena, R.C.
INTRODUCTION: Hepatic micro metastases lead to early recurrence after surgery for hepatocellular carcinoma (HCC). Trans arterial therapy (TAT) without selective embolization may be an effective treatment that induces tumour necrosis. This potential has not been investigated before. This study looks in to the tolerability of TAT in patients after major hepatectomy. MATERIAL AND METHODS: Consented patients were offered trans arterial chemotherapy after normalization of liver functions following surgery. Through the femoral artery, right and left hepatic arteries were selectively cannulated. Doxorubicin 50mg was mixed with 10ml of Lipidol and injected. Post procedure biochemistry and complications were assessed at day 3, 7 and 14 intervals. RESULTS: 11 Patients consented (81% males, median age 61y [range 47y-76y]. There were 7(63.6%) cirrhotics. Four (36.3%) were extended right or left hepatectomies while others were bisegmentectomies. The median time period from surgery to chemotherapy was 25 weeks (range 4-60weeks). Post procedure, 1 (9%) had right hypochondrial pain, 2 (18.1%) had fever, 4(36.3%) had nausea, 2(18.1%) had vomiting within 48 hours. All were discharged at 48 hours. One patient developed a transient bradycardia during procedure. There was no clinical evidence of liver failure. Two patients had three-FOLD rise in transaminase levels at day3 and 7. All recovered by day 14. None of the patients had significant rise in prothrombin time or bilirubin levels. CONCLUSIONS: Post hepatectomy adjuvant trans –arterial chemotherapy is a well-tolerated procedure in the view of short term complications.
