Clinicopathological Characteristics of Hepatocellular Carcinoma in Turkey
(Asian Pacific Organization Cancer Prevention, 2012) Dogan, Erkan; Yalcin, Suayib; Koca, Dogan; Olmez, Aydemir
Background: Hepatocellular carcinoma (HCC), the main malignant tumor of the liver, is very common and highly lethal. The aim of this study was to determine its clinicopathologic characteristics and risk factors in Turkey. Materials and methods: In this study, patients who were diagnosed as suffering from HCC in the period between August 2004 and December 2011 were evaluated retrospectively. Results: A total of 98 patients were included, with a median age 61 (range: 16 to 82). Seventy nine (80.6%) were male 59 (60.2%) were infected with hepatitis B virus (HBV) and 15 (15.3%) with HCV, another 15 (15.3%) being alcohol abusers. Seventy two (73.5%) were at advanced stage and 54 (55.1%) had elevated serum alpha-fetoprotein (AFP). Surgery, chemoembolization, systemic chemotherapy and application of the tyrosine kinase inhibitor sorafenib were the major treatment options. Conclusions: According to our findings HCC is mostly diagnosed in advanced stage and age, being five times more common in males than females. Main risk factors of HCC are HBV infection, HCV infection and alcohol abuse. Elevation in AFP may facilitate early diagnosis of HCC in high risk groups.

Jejunal Diverticulum Perforation Resulting From Distal Mechanic Obstruction: a Case Report
(Aves, 2011) Olmez, Aydemir; Sumer, Aziz; Piskin, Turgut; Aydin, Cemalettin
Excluding Meckel's diverticulum, jejunum and ileum diverticula are acquired diverticula which are rarely observed and have an asymptomatic course. They are mostly observed in elderly patients. Men are twice as likely as women to have diverticula. The complications like inflammation, bleeding, obstruction and perforation may develop in less than 10% of patients with jejunal diverticula. Perforation, as an uncommon complication, may occur following diverticulitis in 82%, blunt trauma in 12%, and impact of foreign body in 6% of cases. Herein we present a 62 year old man operated emergently due to development of acute abdomen that resulted from perforation caused by an increased jejunal and diverticular pressure secondary to rectal obstruction without any common factors mentioned for diverticular perforation. We performed resection and anastomosis at operation.
Orifice Location Guided Excision and Flap Procedures for Treatment of Sacrococcygeal Pilonidal Disease
(Wroclaw Medical Univ, 2011) Piskin, Turgut; Olmez, Aydemir; Mecit, Eren A.; Unal, Bulent; Aydin, Cemalettin; Kayaalp, Cuneyt
Background. Although various surgical techniques have been described, there is no consensus on the optimal treatment for sacrococcygeal pilonidal disease (SPD). Objectives. The aim of this study is to report the medium-term results of three different surgical methods used to treat SPD that were chosen according to the localization of the sinus orifices. Material and Methods. Between November 2005 and April 2007, 43 patients with symptomatic SPD were treated by three different surgical methods. A classic approach, a modified flap technique and a new excision and flap technique were evaluated for treating SPD cases with different localizations of the sinus orifices. The study was carried out on the basis of retrospective reviews of patient charts and telephone interviews for prospective evaluation. Outcome measures included wound complications, time off work, complete healing time, paresthesia, recurrence rates and satisfaction with the procedures and outcomes. Results. There were no early postoperative complication among the 43 patients. The median hospitalization time was 6.76 days (2-12 days). The authors reached 31 patients (72.09%) by phone for the interview; the median follow-up time was 48.41 months (range 42-59 months). No recurrences were reported. The median time off work and complete healing time were 20.54 and 18.61 days, respectively. All but three of the patients reported satisfaction with the esthetic outcome. All the patients reported satisfaction with the effectiveness of the surgical approaches used. One patient reported dissatisfaction with the anesthesia technique. There were complaints of paresthesia from eight patients (one severe, seven moderate). All the patients said that they would recommend these operations and anesthesia techniques to relatives or other patients with sacrococcygeal pilonidal disease. Conclusions. Different excision and flap methods should be used to treat cases of sacrococcygeal pilonidal disease with different localizations of the sinus orifices (Adv Clin Exp Med 2011, 2011, 4, 481-488).
Outcome of Surgical Treatment of Intestinal Perforation in Typhoid Fever
(Baishideng Publishing Group inc, 2010) Sumer, Aziz; Kemik, Ozgur; Dulger, Ahmet Cumhur; Olmez, Aydemir; Hasirci, Ismail; Kisli, Erol; Kotan, Cetin
AIM: To represent our clinical experience in the treatment of intestinal perforation arising from typhoid fever. METHODS: The records of 22 surgically-treated patients with typhoid intestinal perforation were evaluated retrospectively. RESULTS: There were 18 males and 4 females, mean age 37 years (range, 8-64 years). Presenting symptoms were fever, abdominal pain, diarrhea or constipation. Sixteen cases were subjected to segmental resection and end-to-end anastomosis, while 3 cases received 2-layered primary repair following debridement, one case with multiple perforations received 2-layered primary repair and end ileostomy, one case received segmental resection and end-to-end anastomosis followed by an end ileostomy, and one case received segmental resection and end ileostomy with mucous fistula operation. Postoperative morbidity was seen in 5 cases and mortality was found in one case. CONCLUSION: Intestinal perforation resulting from Salmonella typhi is an important health problem in Eastern and Southeastern Turkey. In management of this illness, early and appropriate surgical intervention is vital. (C) 2010 Baishideng. All rights reserved.

Small Bowel Obstruction Due To Mesodiverticular Band of Meckel's Diverticulum: a Case Report
(Hindawi Ltd, 2010) Sumer, Aziz; Kemik, Ozgur; Olmez, Aydemir; Dulger, A. Cumhur; Hasirci, Ismail; Iliklerden, Umit; Kotan, Cetin
Meckel's diverticulum is the most common congenital anomaly of the small intestine. Common complications related to a Meckel's diverticulum include haemorrhage, intestinal obstruction, and inflammation. Small bowel obstruction due to mesodiverticular band of Meckel's diverticulum is a rare complication. Herein, we report the diagnosis and management of a small bowel obstruction occurring due to mesodiverticular band of a Meckel's diverticulum.
T-Tube Bridging for the Management of Biliary Tree Injuries
(int Scientific Literature, inc, 2012) Olmez, Aydemir; Hatipoglu, Sinan; Itik, Veyis; Kotan, Cetin
Background: Injuries of the biliary tree, which mainly occur as a complication of laparoscopic cholecystectomy, are a potentially life threatening cause of high morbidity and mortality. The reported frequency of biliary injuries after laparoscopic cholecystectomy is from 0.5-0.8%. Such injuries may sometimes become too complicated for surgical repair. Presented here is the case of a patient with a major bile duct injury for whom bile duct continuity was achieved using a T-tube. Case Report: A 53-year-old man, who developed bile duct injury following a laparoscopic cholecystectomy performed in another center for cholelithiasis, was referred to our clinic. A Roux-en-Y hepaticojejunostomy was performed in the early postoperative period. However, ensuing anastomotic leakage prompted undoing of the hepaticojejunostomy followed by placement of a T-tube by which bile duct continuity was achieved. Conclusions: For injuries with tissue loss requiring external drainage, T-tube bridging offers a feasible option in that it provides bile duct continuity with biliary flow into the duodenum, as well as achieving external drainage, thus alleviating the need for further definitive surgery.
