| 1 | Reaching proficiency in laparoscopic splenectomy显示文摘AIM:To investigate the proficiency level reached in laparoscopic splenectomy using the learning curve method.METHODS:All patients in need of splenectomy for benign causes in whom laparoscopic splenectomy was attempted by a single surgeon during a time period of 6 years were included in the study (n=33). Besides demographics, operation-related variables and the response to surgery were recorded. The patients were allocated to groups of five, ranked according to the date of the operation. Operation duration, complications, postoperative length of stay, conversion to laparotomy and splenic weight were then compared between these groups.RESULTS: There was a significant difference regarding operation times between the groups (P = 0.001). An improvement was observed after the first 5 cases. The learning curve was flat up to the 25th case. Following the 25th case the operation times decreased still further. There was no difference between the groups regarding the other parameters.CONCLUSION: Unlike the widely accepted 'L' shape, the learning curve for laparoscopic splenectomy is a horizontal lazy 'S' with two distinct slopes. Privileges may be granted after the first 5 cases. However proficiency seems to require 25 cases. | Tarik Zafer Nursal Ali Ezer Sedat Belli Alper Parlakgumus Kenan Caliskan Turgut Noyan | 2009 | World Journal of Gastroenterology2009，15，32： | 3 |
| 2 | Mattress sutures for the modification of end-to-end dunking pancreaticojejunostomy显示文摘Despite the improvement of surgical techniques,the rate of anastomotic failure of pancreaticojejunostomy remains high(30%-50%).Here we describe the use of vertical mattress sutures in the modification of dunking pancreaticojejunal anastomosis.In 7 patients who used this technique,neither anastomotic failure nor any major postsurgical complication developed.This technique is an easy,safe,and promising for the performance of pancreaticojejunostomy. | Nurkan Torer Ali Ezer Tarlk Zafer Nursal | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，5： | 1 |
| 3 | Incidence of congenital hemolytic anemias in young cholelithiasis patients显示文摘AIM: To clarify the incidence of congenital hemolytic anemias (CHA) in young cholelithiasis patients and to determine a possible screening test based on the results. METHODS: Young cholelithiasis patients (< 35 years) were invited to our outpatient clinic. Participants were asked for comorbidities and family history. The number of gallstones were recorded. Blood samples were obtained to perform a complete blood count, standard Wright-Giemsa staining, reticulocyte count, hemoglobin (Hb) electrophoresis, serum lactate dehydrogenase and bilirubin levels, and lipid profile. RESULTS: Of 3226 cholecystectomy patients, 199 were under 35 years, and 190 with no diagnosis of CHA were invited to take part in the study. Fifty three patients consented to the study. The median age was 29 years (range, 17-35 years), 5 were male and 48 were female. Twelve patients (22.6%) were diagnosed as thalassemia trait and/or ?ron-deficiency anemia. Hblevels were significantly lower (P = 0.046), and mean corpuscular volume (MCV) and hematocrit levels were slightly lower (P = 0.072 and 0.082, respectively) than normal. There was also a significantly lower number of gallstones with the diagnosis (P = 0.007). CONCLUSION: In endemic regions, for young cholelithiasis patients (age under 35) with 2-5 gallstones, the clinician/surgeon should pay attention to MCV and Hb levels as indicative of CHA. | Ali Ezer Nurkan Torer Tarik Zafer Nursal Ebru Kizilkilic Kenan Caliskan Tamer Colakoglu Gokhan Moray | 2010 | World Journal of Gastroenterology2010，16，43： | 1 |
| 4 | Giant hepatic hydatid cyst: A case report显示文摘Large type 1 cysts are prone to perforation. Furthermore, insufficient drainage with subsequent abscess is a frequent problem of large cysts. We report here a case of a 19-year old man who was admitted to the hospital with pain in the right upper quadrant and epigastric region. An asymmetrical right upper quadrant enlargement was detected on physical examination. Ultrasonography and computerized tomography revealed a type 1 giant hydatid cyst in the right hepatic lobe, measuring 16 cm in diameter. During operation, partial cystectomy and drainage were done. The large dead space was obliterated by the ‘sandwich’ method. Omentum and gelatin sponges were used to fill the cavity. The postoperative period was uneventful and the patient was discharged on the 5th postoperative day. | Ali Ezer Tar■k Zafer Nursal Turgut Noyan Gkhan Moray | 2007 | World Journal of Gastroenterology2007，13，16： | 0 |
