Hydatidosis is a zoonotic infection and treatment is mandatory to avoid complications. Surgery remains the frst choice in the treatment especially for CE2-CE3b cysts. Open or laparoscopic approaches are available. However, comparative studies are limited. Materials and Methods. Data of patients who underwent cystotomy/partial cystectomy for liver hydatidosis between January 2012 and September 2016 (n=77) were evaluated retrospectively. Recurrent cases and the patients with previous hepatobiliary surgery were excluded. 23 patients were operated upon laparoscopically and named as Group 1. 48 patients operated conventionally named as Group 2. Demographics, cyst characteristics, operative time, length of hospital stay, recurrences, and surgery related complications were evaluated. Results. Groups were similar in terms of demographics, cyst characteristics, and operative time. Te length of hospital stay was 3.4 days in Group 1 and 4.7 days in Group 2 (p=0,007). Te mean follow-up period was 17.8 months and 21.7 months, respectively (p=0.170). Overall complication rates were similar in two groups (p=0.764). Tree conversion cases occurred (13%). One mortality was seen in Group 2. Four recurrences occurred in each group (17% versus 8.3%, respectively) (p=0.258). Conclusions. Laparoscopy is a safe and feasible approach for surgical treatment of liver hydatidosis. Recurrence may be prevented by selection of appropriate cases in which exposure of cysts does not pose an intraoperative difcultyPublication Metadata only Serum ve periton sıvısı CEA ve CA 19-9 değerlerinin mide adenokarsinomu TNM evresi ve peritoneal yayılımının belirlenmesindeki etkisi(2016-04-17) BEKTAŞOĞLU, HÜSEYİN KAZIM; HASBAHCECI, MUSTAFA; MALYA, FATMA ÜMİT; AKÇAKAYA, ADEM; KUNDUZ, ENVER; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; AKÇAKAYA, ADEMPublication Open Access Co-existence of acute appendicitis and inflammatory myofibroblastic tumor of the small intestine: A case report(2015-09-01) Unver, NURCAN; Coban, GANİME; ONARAN, Oyku Izel; ARSLAN, ADNAN; Malya, FATMA ÜMİT; HASBAHCECI, Mustafa; ÜNVER, NURCAN; ÇOBAN, GANİME; KUNDUZ, ENVER; ARSLAN, ADNAN; MALYA, FATMA ÜMİTIntroduction: Inflammatory myofibroblastic tumor as a rare neoplastic lesion is seen most commonly in the pulmonary system. Beside the presence of limited number of inflammatory myofibroblastic tumors of the gastrointestinal tract in the literature, co-existence with acute appendicitis has not been reported before. Presentation of case: A 27-year-old woman admitted to emergency department with acute abdominal pain at the right lower quadrant. The initial diagnosis was as acute appendicitis. Intraoperatively, a mass with a diameter of almost 5 cm originated from the distal ileal segments neighboring the appendix was seen. The patient was managed by segmental resection of the small intestine including the mass with appendectomy. Histologically, there were bundles of spindle cells accompanied by lymphoplasmocytic infiltration. The immunohistochemical studies showed that tumor cells were positive for smooth muscle actin, vimentin, perinuclear activity for anaplastic lymphoma kinase and CD 68. The final pathologic diagnosis was inflammatory myofibroblastic tumor. Discussion: Concomitant resection of tumoral lesions detected in the neighbor intestinal segments during appendectomy should be considered to diagnose and treat. For the diagnosis of inflammatory myofibroblastic tumor, immunohistochemistry pattern including positivity for actin, vimentin, CD 68 and anaplastic lymphoma kinase plays a crucial role. Therefore, detailed immunohistochemistry analysis should be performed in suspicious cases. Conclusion: Coexistence of inflammatory myofibroblastic tumor located in the gastrointestinal system with acute appendicitis is a rare event. Complete surgical excision should be regarded as the mainstay of the treatment. Long-term follow up with serial imaging techniques is recommended.Publication Metadata only Dalak koruyucu laparoskopik distal pankreatektomi(2015-04-04) MALYA, FATMA ÜMİT; HASBAHCECI, MUSTAFA; KUNDUZ, ENVER; TAŞCI, YUNUS; CENGİZ, MERVE BÜŞRA; ERSOY, YELİZ EMİNE; BOZKURT, SÜLEYMAN; AKÇAKAYA, ADEM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; ERSOY, YELIZ EMINE; BOZKURT, SÜLEYMAN; AKÇAKAYA, ADEMPublication Metadata only Effects of Intraperitoneal Bevacizumab Administration on Colonic Anastomosis and Early Postoperative Adhesion Formation(2013-12-01T00:00:00Z) Karanlik, Hasan; KURT, ATİLLA; Kunduz, Enver; Serin, Kursat; Saglam, Sezer; Soydinc, Hilal Oguz; Yasasever, Vildan; Olgac, Vakur; Asoglu, Oktar; KUNDUZ, ENVERAim. The purpose of this study is to investigate the effect of intraperitoneal (IP) bevacizumab on colonic anastomosis and evaluate the effects on early postoperative adhesion formation. Materials and Methods. A total of 24 mature female Sprague-Dawley rats were used for this study. Rats were randomly assigned to a control group that received saline (n = 8) or to experimental groups (n = 8 each) that received bevacizumab at a dose of 2.5 mg/kg (group 1) or 5 mg/kg (group 2). Animals were killed humanely on the seventh day after operation, and measurements of anastomotic strength and biochemical variables were performed. Results. The mean adhesion grade was 2.63 +/- 0.92, and 1 +/- 0.93 and 0.75 +/- 0.71 for the control and test groups, respectively. Bevacizumab significantly reduced adhesion formation in both low-dose and high-dose IP applications (P < .05). When all groups were compared, it was found that VEGF levels decreased significantly only in the tissue (P = .001), whereas there was no significant difference in the blood and the IP fluid (P = .73 and .08, respectively). We evaluated hydroxyproline levels, anastomosis bursting pressure, and histopathological healing scores. When each of these parameters were examined, there was statistical difference between groups (P = .01, .004, and .01, respectively). It was found that these parameters significantly decreased depending on increasing drug dose. Conclusion. IP administration of bevacizumab effectively reduced the formation of adhesions and caused significant impairment of anastomotic wound healing when standard doses were administered (5 mg/kg), but the 2.5-mg/kg dosage did not affect the anastomotic wound healing and also effectively reduced the formation of adhesions.Publication Metadata only Sağ kolon adenokarsinomlarında yüksek bağlama-apikal lenf nodu eksizyonunun postoperatif morbidite ve lenf nodu disseksiyon kalitesine etkisi(2016-04-17) KUNDUZ, ENVER; CENGİZ, Merve Büşra; HASBAHCECI, Mustafa; MALYA, FATMA ÜMİT; Bektaşoğlu, HÜSEYİN KAZIM; KUNDUZ, ENVER; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; AKÇAKAYA, ADEM
