Publication Open Access Comparison of Laparoscopic and Conventional Cystotomy/Partial Cystectomy in Treatment of Liver Hydatidosis(2019-01-01) Bektasoglu, HÜSEYİN KAZIM; HASBAHCECI, Mustafa; Taşçı, Yunus; Aydogdu, Ibrahim; MALYA, FATMA ÜMİT; Kunduz, ENVER; Dolay, KEMAL; BEKTAŞOĞLU, HÜSEYİN KAZIM; AYDOĞDU, İBRAHİM; MALYA, FATMA ÜMİT; KUNDUZ, ENVER; DOLAY, KEMALIntroduction. 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 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 Open Access Laparoscopic surgery in distal pancreatic tumors(2017-12-01) Malya, FATMA ÜMİT; Bektaşoğlu, HÜSEYİN KAZIM; HASBAHCECI, Mustafa; Taşçı, Yunus; Kunduz, ENVER; Karatepe, Oguzhan; Dolay, KEMAL; MALYA, FATMA ÜMİT; BEKTAŞOĞLU, HÜSEYİN KAZIM; KUNDUZ, ENVER; DOLAY, KEMALObjective: Laparoscopic distal pancreatectomy is increasingly being used in the surgical treatment of corpus and distal pancreatic tumors. In this study, patients who underwent laparoscopic or open distal pancreatectomy for benign or malignant causes were evaluated in terms of tumor characteristics and perioperative outcomes. Material and Methods: We retrospectively reviewed data from a total of 27 distal pancreatectomy cases performed for benign or malignant causes in the General Surgery Department between January 2013 and December 2015. Groups were compared according to the demographic characteristics of patients, operation type (laparoscopic or open, with splenectomy or spleen preservation), operation time, surgical site infection (superficial, deep wound infection, or intra-abdominal abscess), pancreatic fistula development, and histopathological examination results. Results: Both groups were similar in terms of age, sex, and body mass index (p=0.42). Tumor diameter was similar (p=0.18). The total number of resected lymph nodes was similar in both groups (p=0.6). Pancreatic fistula developed in one patient in each group. Mean hospital stay duration and the amount of intraoperative bleeding were similar in both groups. The laparoscopy group had a markedly lower overall morbidity rate (p=0.08). There was no mortality observed in the study subjects. Conclusion: Laparoscopic distal pancreatectomy can be safely performed as a minimally invasive procedure in experienced centers and in selected cases without increasing perioperative complication rates, particularly in benign cases. Although oncological outcomes are acceptable for malignant cases, future prospective controlled studies are necessary for more reliable evaluation.

Methods: this study was a retrospective analysis of patients (age ≥ 18 years) who underwent percutaneous cholecystostomy due to acute calculous cholecystitis. Patients were grouped according to treatment modality: percutaneous cholecystostomy as a definitive treatment (group 1), subsequent surgical treatment after the removal of the catheter (group 2) and those remaining in situ (group 3). The development of gallstone-related complications was the main outcome. Results: there were 24 females (43.6%) and 31 males (56.4%) included in the study with a mean age of 64.8 ± 15.9 years. There were 16 (29.1%), 19 (34.5%) and 20 (36.4%) patients in groups 1, 2, and 3, respectively. The catheter withdrawal time for group 1 and group 2 was 18.2 ± 6.9 and 20.7 ± 13.4 days, respectively. Surgical treatment was performed after a mean of 85.4 ± 93.5 days following catheter removal in group 2 and a mean of 64 ± 32.5 days while the PC tube was in place in group 3. There were one (6.3%) and two cases of a recurrence (10.5%) in groups 1 and 2, respectively. Two patients developed choledocholithiasis (10%) in group 3. Conclusion: maintaining percutaneous cholecystostomy tubes in place until the time of surgery in surgically fit patients may help to prevent a recurrence after acute calculous cholecystitis.Publication Open Access A rare cause of obstructive defecation in a 29-year-old woman: Ileo-colo-colonic intussusception treated by subtotal colectomy with posterior rectopexy(2018-12-01) Kunduz, ENVER; Malya, FATMA ÜMİT; Mehdi, Elnur; HASBAHCECI, Mustafa; KUNDUZ, ENVER; MALYA, FATMA ÜMİTAdult intussusception is a rare clinical condition. In majority of adult cases, there is an underlying cause such as polyps or colon cancers. In the present study, a 29-year-old woman with intermittent and colicky abdominal pain, constipation, and painful defecation, accompanied with distention and sense of rectal fullness, was evaluated with computed tomography. Ileo-colo-colic intussusception was determined. Subtotal colectomy with posterior rectopexy was performed. After the surgery, she was doing well at 13-month follow-up.Publication Open Access Use of peritoneal washing cytology for the detection of free peritoneal cancer cells before and after surgical treatment of gastric adenocarcinoma(2018-10-01) HASBAHCECI, Mustafa; Akcakaya, ADEM; Guler, BERİL; Kunduz, ENVER; Malya, FATMA ÜMİT; Muslumanoglu, Mahmut; AKÇAKAYA, ADEM; GÜLER, BERIL; KUNDUZ, ENVER; MALYA, FATMA ÜMİTAim: Cytological detection of peritoneal-free gastric cancer cells is considered as the gold standard with variable sensitivity. Seeding of cancer cells after radical surgery for gastric cancer is a controversial issue. In this study, it was aimed to detect the rate of positive peritoneal washing cytology and the incidence of spreading of tumor cells after radical surgery. Materials and methods: Patients with pathologically proven and surgically treated gastric adenocarcinoma were enrolled. Three peritoneal washing samples were examined cytologically: at the beginning, after completion of resection, and before closure of the abdomen. Identification of peritoneal-free gastric cancer cells was regarded as the main outcome. Results: Thirty-four patients with a mean age of 60.7 ± 12 years were enrolled. T3 and N0 were the most common stages seen in 16 (47%) and 12 patients (35.3%), respectively. There were two positive results (5.9%) as the first peritoneal sample. Considering T3- or N-positive patients, the incidence increased to 9.1%. There was no conversion of negative to positive cytology. Cytological positivity remained only in one case (2.9%) after the second and the third peritoneal samples. Conclusion: Rate of positive peritoneal washing cytology in patients with gastric cancer is influenced by clinicopathological findings and the technique used. Use of cytology alone is thought to be failed to detect free cancers cells within the peritoneal cavity.
