This study was performed to analyze the efficacy of the prophylactic use of octreotide (Novartis, Stein, Switzerland) for pancreatic fistula following a pancreaticoduodenectomy. The medical records of 190 patients who underwent a pancreaticoduodenectomy at the Samsung Medical Center in Seoul, Korea between January 2000 and December 2002 were reviewed. Patients were divided into either the octreotide (n = 81) or control group (n = 109). The octreotide group received subcutaneous injections of 100 microgramg of octreotide every 12 hours for more than five days after surgery. The control group was not treated with octreotide. The criterion of pancreatic fistula was the drainage of the amylase rich fluid, over 500 U/mL in the three days after surgery. The morbidity and mortality rates were 32.1% and 1.2% in the octreotide group and 31.2% and 0% in the control group, respectively. Pancreatic fistula was the second most common complication (8.4%). In the univariate analysis, octreotide was ineffective in reducing pancreatic fistula (p = 0.26). However, in the multivariate regression analysis, combined gastrectomy (p = 0.018), cellular origin of the disease (p = 0.049), and use of octreotide (p = 0.044) were the risk factors that increased the frequency of pancreatic fistula. Therefore, the routine use of octreotide after a pancreaticoduodenectomy should be avoided until a worldwide consensus is established.

BACKGROUNDS/AIMS: Gastrointestinal decompression by nasogastric or intestinal tubes developed in 1930s has been the only treatment modality for inoperable intestinal obstruction. We hypothesized that the octreotide, a potent inhibitor of intestinal secretion, has a therapeutic potential in intestinal obstruction. METHODS: Forty Sprague-Dawley rats were randomly assigned to four groups. The rats were subjected to complete or partial ileal obstruction. The treated rats received octreotide (100 microgram/kg) while the controls received the same quantity of saline every 12 hours for 24 or 48 hours. After 24 or 48 hours, the volumes of the small bowel contents were measured. The volumes of supernatant and the concentrations of electrolytes in the small bowel contents after centrifugation were also analyzed. The ileal segments proximal to obstruction were harvested, fixed, and stained, and the pathological changes were evaluated with mucosal damage scores. RESULTS: There were no statistical differences in the volume and the electrolyte composition of intestinal fluid among the 4 groups. In the 48 hour complete obstruction group, the octreotide-treated rats showed statistically lower mucosal damage scores than the control rats (p<0.05). CONCLUSIONS: Octreotide exerts mucosal protecting effect on the complete intestinal obstruction rat model.

OBJECTIVE: To explore the protective effect of octreotide on liver warm ischemia-reperfusion injury and its possible mechanism. METHODS: Pringle's maneuver liver ischemia-reperfusion models were established. Forty eight male Sprague Daweley rats were randomly divided into a sham operation group (S group, n=16), an ischemia-reperfusion group (I/R group, n=16) and an octreotide preconditioning group (OPC group, n=16). ALT and AST in the serum were measured at 30 min after the ischemia and 120 min after the reperfusion. The histomorphological changes and ultrastructure of hepatocellular were observed by optic and transmission electronic microscope. Hepatic adenine nucleotide levels and energy changes (EC) were determined by high performance liquid chromatography (HPLC). RESULTS: (1) At 30 min after the ischemia and 120 min after the reperfusion, the levels of ALT and AST in the serum of OPC group was lower than those in I/R group, whereas the levels of ATP and EC in the hepatic tissue were higher than those in the I/R group (P<0.01 or P<0.05). Compared with the I/R group, the injury of hepatocellular histomorphology and ultrastructure in the OPC group was abated. (2) At 30, 60, and 120 min after the reperfusion, the levels of ATP and EC in the OPC groups were higher than those in the I/R group. During the ischemia, the levels of ATP and EC in the OPC group dropped more slowly than those in the I/R group, but ATP and EC in the OPC groups rose more quickly than those in the I/R group during the reperfusion. CONCLUSION Octreotide precondition can improve the hepatocellular energy reserve, and protect the liver from warm ischemia-reperfusion injury. The protective of octreotide on warm ischemia-reperfusion injury may be related to its influence on endocrine secretion.

BACKGROUND/AIMS: Terlipressin and octreotide had been used to control acute variceal bleeding and to prevent early rebleeding after endoscopic hemostasis. We compared the efficacy and safety of terlipressin and octreotide combined with endoscopic variceal ligation (EVL) for the treatment of acute esophageal variceal bleeding and we evaluated their clinical significance as related to rebleeding. METHODS: The eighty eight cirrhotic patients were randomized to the terlipressin group (n=43; 2 mg i.v. initially and 1 mg i.v. at every 4 hours for 3 days) or the octreotide group (n=45; continuous infusion of 25 microgram/h for 5 days) combined with EVL for the treatment of acute esophageal variceal bleeding. RESULTS: The initial hemostasis rates were 98% (42/43 cases) in the terlipressin group and 96% (43/45 cases) in the octreotide group. The 5-day and 42-day rebleeding rates were 12% (5/43 cases) and 28% (12/43 cases), respectively, in the terlipressin group and 9% (4/45 cases) and 24% (11/45 cases), respectively, in the octreotide group. No significant difference was demonstrated between the terlipressin and octreotide groups. The mortality at 42 days was similar in both group, but a high mortality rate (48%) was shown to be related to 42-day rebleeding. The risk factors related to 42-day rebleeding were Child-Pugh class C (aOR=30.2, 95% CI=7.7-117.9), ascites above grade II (aOR=6.6, 95% CI=2.2-19.2) and advanced hepatocellular carcinoma (aOR=4.6, 95% CI=1.1-18.9). CONCLUSIONS: Comparing terlipressin and octreotide combined with EVL showed them to be equally safe and effective therapeutic agents in patients with acute esophageal variceal bleeding. The high risk factors related to early rebleeding were poor liver function and advanced hepatocellular carcinoma.

OBJECTIVETo investigate the effect of utilizing octreotide during perioperative period on pancreatic fistula after pancreaticoduodenectomy (PD).

METHODSThree hundreds and six patients admitted from January 2010 to October 2014, who prepared to undergo pancreaticoduodenectomy (PD) were randomly divided into octreotide group (147 cases) and control group (159 cases). In octreotide group, octreotide was used in subcutaneous injection instantly after PD, each 8 hours until postoperative 10(th) day, and patients in control group were injected with the same volume of saline. Differences of pancreatic fistula (Grade A, Grade B, Grade C), hospitalization days and treatment cost were compared. χ(2) test, t-test and Fisher exact test were used to analyzed to the data, respectively.

RESULTSNo statistical significance (P>0.05) between two groups in the incidence of pancreatic fistula after PD (Grade A: 8.8% vs. 10.2%, Grade B: 2.7% vs. 4.4%, Grade C: 0.7% vs. 1.3%; χ(2)=0.197, 0.700, 0.288; P=0.657, 0.403, 0.591), the length of hospitalization((12.1±1.2)days vs. (13.0±1.2)days)(t=1.711, P=0.104) and treatment cost (79 700±6 700 vs. 77 600±5 200)(t=1.378, P=0.185). When accompanied with high risk factors, such as soft texture of pancreas, pancreatic duct size less than 3 mm, BMI≥25 kg/m(2) and diabetes, compared with control group, octreotide group had the lower incidence rate of pancreatic fistula and clinical correlative pancreatic fistula(all P<0.05) after PD.

CONCLUSIONSGenerally, octreotide makes no contribution to reduce the incidence of pancreatic fistula after PD. However, for patients who is accompanied with high risk factors, such as soft texture of pancreas, pancreatic duct size less than 3 mm, BMI≥25 kg/m(2) and diabetes, octreotide can effectively prevent pancreatic fistula after PD.

BACKGROUNDLittle information about the current management of patients with thyroid-stimulating hormone (TSH)-secreting pituitary adenomas or about the usefulness of the somatostatin analogue octreotide was contained in the literature. This study aimed to report the efficacy and safety of the long-acting octreotide formulation in patients with TSH-secreting pituitary adenomas after incomplete surgery and octreotide treatment failure.

METHODSFifteen patients with TSH-secreting pituitary adenomas (8 men and 7 women), who previously underwent incomplete surgical resection and/or adjuvant radiotherapy (n = 12) and failure of octreotide treatment (n = 15), followed between 2007 and 2010 in Beijing Tiantan Hospital were included in this study. All patients received 1- to 2-months of the long-acting octreotide formulation treatment after the above combination of treatment. Paired samples t-test was used to analysis the variables.

RESULTSAfter two-month duration of the long-acting octreotide formulation treatment, the mean serum free or unbound thyroxine (FT4) ((16.02 ± 1.72) pmol/L) and free triiodothyronine (FT3) ((2.87 ± 0.43) pmol/L) levels of 15 patients significantly decreased compared with those after octreotide-treatment (FT4, (35.36 ± 7.42) pmol/L, P < 0.001; FT3, (17.85 ± 7.22) pmol/L, P < 0.001). Mean TSH levels stayed in the normal range after the long-acting octreotide formulation treatment ((0.72 ± 0.21) mU/L) and were significantly lower than the pretreatment value ((5.27 ± 1.04) mU/L, P < 0.001), post-surgery value ((3.37 ± 0.31) mU/L, P < 0.001) and post-octreotide-treatment value ((4.52 ± 0.41) mU/L, P < 0.001). In these patients with TSH-secreting pituitary adenomas there was no evidence of tachyphylaxis.

CONCLUSIONThe long-acting octreotide formulation may be a useful and safe therapeutic tool to facilitate the medical treatment of TSH-secreting pituitary adenomas in patients who underwent incomplete surgery or need long-term somatostatin analog therapy.
