Intra-arterial bolus octreotide administration during Whipple procedure in patients with fragile pancreas: a novel technique for safer pancreaticojejunostomy. J Surg Oncol. 2005;89(4):268-72.
AbstractBACKGROUND AND OBJECTIVES: Leakage from the pancreaticojujenostomy is the most serious complication of Whipple. Pancreatic fistula rate is higher in cases of fragile pancreas often seen in duodenal carcinomas and carcinomas of the ampulla of Vater. Octreotide administration has been used for the prevention of fistula formation through the subcutaneous route. Due to its physiologic effects to the pancreatic parenchyma the intra-arterial administration of octreotide could provide tissue hardening that allows for a technically easier anastomosis while maintaining its protective role for fistula formation.
METHODS: Octreotide was injected directly into the distal part of the gastroduodenal artery (GDA) in four patients undergoing Whipple for histologically proven periampullary cancer.
RESULTS: Tissue hardening after octreotide administration was evident not only in surgeons' hands but in the intra-operative ultrasound as well. The three patients were discharged on day 9, 11, and 13; they had an uneventful postoperative course, while one patient had a minor bile leak from the choledojejunal anastomosis and was discharged on day 22.
CONCLUSIONS: The intra-arterial administration of octreotide during Whipple is a safe procedure and provides tissue hardening thus making the performance of the anastomosis technically easier. The actual benefit in terms of morbidity, mortality, and fistula rate are to be further evaluated.

Gardner's syndrome: a case report and review of the literature. World J Gastroenterol. 2005;11(34):5408-11.
AbstractGardner's syndrome is an autosomal dominant disease characterized by the presence of colonic polyposis, osteomas and a multitude of soft tissue tumors. The syndrome may present at any age from 2 mo to 70 years with a variety of symptoms, either colonic or extracolonic. We present a case of a 11-year-old female patient with Gardner's syndrome who presented with a lumbar area desmoid tumor and treated with resection of the desmoid, restorative proctocolectomy and ileal pouch anal anastomosis, A review of the current literature has been performed.

Electrothermal bipolar vessel sealing system is a safe and time-saving alternative to classic suture ligation in total thyroidectomy. Head Neck. 2005;27(11):959-62.
AbstractBACKGROUND: Total thyroidectomy is associated with minimal morbidity. The electrothermal bipolar vessel sealing system is an adjunct to the surgical technique, recently made available to thyroid surgery.
METHODS: This is a prospective randomized trial of total thyroidectomies performed in single unit from July 2003 to May 2004. Patients were randomly assigned in two groups: group A (n = 90), total thyroidectomy with the classic suture ligation technique; and group B (n = 94), total thyroidectomy with the use of the electrothermal bipolar vessel sealing system.
RESULTS: Operative time was significantly reduced in group B by 14 minutes (mean difference, 14.3 +/- 4.2 minutes, 95% CI, 5.88-22.6 minutes). No statistically significant differences were found in postoperative complications, postoperative serum calcium measurements, or hospital stay between the two groups.
CONCLUSIONS: The electrothermal bipolar vessel sealing system is a safe and useful, time-saving adjunct for total thyroidectomy.

Effects of mycophenolate mofetil vs cyclosporine administration on graft survival and function after islet allotransplantation in diabetic rats. World J Gastroenterol. 2005;11(18):2733-8.
AbstractAIM: To develop an experimental model of islet allotransplantation in diabetic rats and to determine the positive or adverse effects of MMF as a single agent.
METHODS: Thirty-six male Wistar rats and 18 male Lewis rats were used as recipients and donors respectively. Diabetes was induced by the use of streptozotocin (60 mg/kg) intraperitoneally. Unpurified islets were isolated using the collagenase digestion technique and transplanted into the splenic parenchyma. The recipients were randomly assigned to one of the following three groups: group A (control group) had no immunosuppression; group B received cyclosporine (CsA) (5 mg/kg); group C received mycophenolate mofetil (MMF) (20 mg/kg). The animals were killed on the 12th d. Blood and grafted tissues were obtained for laboratory and histological assessment.
RESULTS: Median allograft survival was significantly higher in the two therapy groups than that in the controls (10 and 12 d for CsA and MMF respectively vs 0 d for the control group, P<0.01). No difference in allograft survival between the CsA and MMF groups was found. However, MMF had less renal and hepatic toxicity and allowed weight gain.
CONCLUSION: Monotherapy with MMF for immunosuppression was safe in an experimental model of islet allotransplantation and was equally effective with cyclosporine, with less toxicity.
