Effect of alpha-tocopherol and dose sensitivity on pancreatitis formation in rats with experimental pancreatitis.

BACKGROUND: Acute pancreatitis is an inflammatory disease accompanied by pancreatic inflammation characterized by acinar cell damage and leukocyte infiltration in the tissue. At present, mortality and morbidity rates are high despite the current treatment of pancreatitis; therefore, new studies and treatment studies are needed. In this study, the effects of alpha-tocopherol on different doses of L-arginine-induced experimental acute pancreatitis model were investigated. METHODS: Thirty adult male Sprague-Dawley albino rats were randomly divided into four groups; control (sham) group (n=6), acute pancreatitis group (n=8), low-dose alpha-tocopherol (200 mg/kg once intraperitoneal [IP]) group (n=8), and high dose alpha-tocopherol (400 mg/kg once ip) group (n=8). Experimental acute pancreatitis model was created by a single IP dose of 5 g/kg of L-arginine. Alpha-tocopherol was administered in a single dose intraperitoneally, 30 min before the creation of the experimental model of acute pancreatitis induced by L-arginine induction in Groups 3 and 4. Tissue and blood samples were taken under anesthesia 72 h after L-arginine injection; then the rats were sacrificed by decapitation. Serum amylase, lipase, interleukin (IL)-1ß, IL-6, tumor necrosis factor (TNF)-alpha, and C-reactive protein (CRP) levels were examined. Pancreatic tissue samples were examined under a light microscope for histopathological examination. RESULTS: When the acute pancreatitis group (Group 2) was compared to the control group (Group 1), serum amylase, lipase, IL-1ß, IL-6, TNF-alpha, and CRP levels were all significantly increased (p<0.05 for all). Histopathological examination showed significant difference in edema (p<0.001) and inflammation (p=0.007) scores. When the low (Group 3) and high (Group 4) dose alpha-tocopherol groups were compared to Group 2, amylase, lipase, IL-1ß, IL-6, TNF-alpha, and CRP parameters were statistically significantly lower (p<0.05 for all). In the histopathological comparison of Groups 2, 3, and 4, edema and inflammation scores were decreased in Groups 3 and 4 compared to Group 2. Comparing Group 4 to Group 3, lipase (p<0.01), IL-6 (p=0.038), and TNF-alpha (p=0.002) levels were significantly decreased; no significant difference was observed in the histopathological evaluation. CONCLUSION: Alpha-tocopherol was found to reduce inflammation and pancreatic damage in acute pancreatitis and was more effective in high doses.

Is it beneficial to use clinical scoring systems for acute appendicitis in adults?

BACKGROUND: Clinical scoring systems have been used to reduce negative appendectomy rate for several decades. However, the use of these systems has been questioned due to differences in their diagnostic accuracies. The aim of this prospective study was to develop a new clinical scoring system using a combination of all previously described variables for the diagnosis of acute appendicitis (AA). METHODS: Consecutive patients who underwent emergency appendectomy for AA between December 2016 and April 2017 were prospectively included in the study. During admission, a prepared questionnaire including variables obtained from the previously used clinical scoring systems was administered. Histopathological analysis was regarded as the main outcome. Patients with no histopathological evidence of AA were defined as negative appendectomy. All variables were analyzed separately to assess their association with AA. A receiver operating characteristic curve with area under curve analysis was performed to obtain the cut-off values for numerical variables. RESULTS: There were 200 patients with a mean age of 30.8±12.8 years with a negative appendectomy rate of 5.5%. There was no significant association between the variables and the detection of histologically proven AA except increased white blood cell count >11.05/mm3 and proportion of the polymorphonuclear leukocytes >71.2% (p=0.003 and p=0.015, respectively). CONCLUSION: The present study shows that the development and/or use of scoring systems does not significantly improve the diagnostic accuracy of AA.

Early laparoscopic cholecystectomy following acute biliary pancreatitis expedites recovery.

BACKGROUND: In this retrospective study, we aimed to assess the reliability of early cholecystectomy, risk of recurrent biliary pancreatitis, and their effects on hospital length of stay and morbidity by comparing the results of early and late laparoscopic cholecystectomy in patients with acute biliary pancreatitis. METHODS: A total of 131 patients, who were diagnosed with acute biliary pancreatitis at Okmeydani Education and Research Hospital in January 2009-December 2012, were included in the study. Demographic specifications of patients, duration of their complaints, biochemistry and hemogram values at first arrival, Ranson criteria, number of attacks, screenings, operation type and period, number of days between the first attack and operation, hospital length of stay, and complications were recorded. Patients who underwent cholecystectomy within the first 2 weeks were considered early (group 1) and those who under the operation after 2 weeks were considered late (group 2). RESULTS: There were 47 patients in group 1 and 84 patients in group 2. Open surgery was not performed on any patient, and there was no choledoch injury and mortality. The average hospital length of stay was 7.6±3.0 days in group 1 and 10.7±8.3 days in group 2, with a statistically significant difference between the groups (p=0.006). Two or more number of attacks occurred in 15 patients in group 2 (18%), with a statistically significant difference between the groups (p=0.000). CONCLUSION: Laparoscopic cholecystectomy is safe as it does not increase operation time and morbidity in biliary pancreatitis with a Ranson score of ≤3 or cause difficulty in dissection. Late cholecystectomy causes recurrent attacks and increases the hospital length of stay and treatment costs. Using randomized controlled studies, the effectiveness and reliability of early cholecystectomy in mild and moderate biliary pancreatitis can be verified.

Solitary caecum diverticulitis mimicking acute appendicitis.

Solitary cecum diverticulum is a benign formation, but it can be complicated with inflammation, perforation and bleeding. Cecum diverticulitis (CD) is the most common complication of caecal diverticulum and it has the highest incidence among Asians, but it is a rare condition in the western world. The incidence of colonic diverticular disease can vary according to national origin, cultural structure and nutritional habits. CD is not common in our country, but it is an important situation because of its clinical similarity with the commonly seen acute right side abdominal diseases like acute appendicitis. Preoperative diagnosis is difficult, and hence, the actual frequency is not known. The treatment of CD can vary from medical therapy to right hemi colectomy. In this study, we presented ten CD cases on whom surgical resection was performed in our surgery unit during the last 8 years. Our purpose was to increase the awareness of surgeons about this situation, and so, make them pay attention for not having their first experience in the operating room.

[Gallbladder torsion as a rare cause of acute abdomen; a case report and review of literature.]. / Akut karnin nadir bir nedeni olarak safra kesesi torsiyonu; olgu sunumu ve literatür derlemesi.

Torsion of the gallbladder is a rare cause of acute surgical abdomen. Less than 300 patients have been reported so far. On the other hand incidence seems to be higher than expected especially in elderly patients. This condition must be suspected in an elderly patient who represents signs and symptoms of toxemia and cholecystitis . Diagnosis is usually established during laparotomy. Torsion occurs at the base of the gallbladder around cystic duct and artery. Treatment is emergent cholecystectomy.
