    The Role of C-Reactive Protein in the Early Prediction of Serious Pancreatic Fistula Development after Pancreaticoduodenectomy
    (2018-01-01T00:00:00Z) MALYA, Fatma Ümit; Hasbahceci, Mustafa; Tasci, Yunus; KADIOĞLU, HÜSEYİN; GÜZEL, Mehmet; Karatepe, Oguzhan; DOLAY, Kemal; MALYA, FATMA ÜMİT; KADIOĞLU, HÜSEYİN; GÜZEL, MEHMET; DOLAY, KEMAL
    Introduction. Despite recent advances in surgical techniques, pancreatic fistulas are common. We aimed to determine the role of C-reactive protein in the prediction of clinically relevant fistula development. Materials and Methods. Data from patients who underwent pancreaticoduodenectomy between 2012 and 2015 is collected. Postoperative 1st, 3rd, and 5th day (POD1, POD3, and POD5) C-reactive protein (CRP) levels, postoperative pancreatic fistula (POPF) development, other complications, length of hospital stay, and mortality were recorded. Results. Of 117 patients, 43 patients (36.8%) developed complications (including fistulas). Of the patients developing fistulas, 21 (17.9%) had POPF A, 2 (1.7%) had POPF B, and 7 (6.0%) had POPF C. POD5 CRP and POD3 CRP were shown to be significantly correlated with mortality and development of clinically relevant POPF (p = 0 001 and p = 0 0001, resp.) and with mortality (p = 0 017), respectively. The development of clinically relevant POPFs (B and C) could be predicted with 90% sensitivity and 82.2% specificity by POD5 CRP cut-off level of 19 mg/dL and with 100% sensitivity and 63.6% specificity by the difference between POD5 and POD1 CRP cut-off level of > 2.5 mg/dL. Conclusion. CRP levels can effectively predict the development of clinically relevant pancreatic fistulas.

    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, KEMAL
    Introduction. 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 difculty

    The correlation between breast cancer and urinary iodine excretion levels
    (2018-02-01) Malya, FATMA ÜMİT; Kadioglu, HÜSEYİN; Hasbahçeci, Mustafa; Dolay, KEMAL; Guzel, MEHMET; Ersoy, YELİZ EMİNE; MALYA, FATMA ÜMİT; KADIOĞLU, HÜSEYİN; DOLAY, KEMAL; GÜZEL, MEHMET; ERSOY, YELIZ EMINE
    Objective To compare urinary iodine excretion levels in patients with breast cancer and control subjects. Methods In this prospective pilot study, patients with breast cancer and normal controls were recruited. Age and menopausal status were recorded. Levels of serum thyroid-stimulating hormone, blood urea nitrogen and creatinine and urine iodine concentration (UIC) were measured. UIC levels were divided into three categories: low (<100 µg/l), normal (100-200 µg/l) or high (>200 µg/l). Results A total of 24 patients with breast cancer and 48 controls were included in the study. There were no statistically significant differences between the two groups with regard to thyroid-stimulating hormone, blood urea nitrogen or creatinine levels. When considered overall, there was no statistical difference in UIC between patients and controls. However, comparisons within each category (low, normal or high UIC) showed a significantly higher percentage of patients with breast cancer had a high UIC compared with controls. Conclusions A high UIC was seen in a significantly higher percentage of patients with breast cancer than controls. UIC may have a role as a marker for breast cancer screening. Further studies evaluating UIC and iodine utilization in patients with breast cancer are warranted.

    Endoscopic diagnosis and treatment of biliary obstruction due to acute cholangitis and acute pancreatitis secondary to Fasciola hepatica infection.
    (2018-01-01) DOLAY, KEMAL; HASBAHCECI, MUSTAFA; HATIPOĞLU, ENGİN; Ümit, Malya; Akçakaya, ADEM; DOLAY, KEMAL; MALYA, FATMA ÜMİT; AKÇAKAYA, ADEM
    In the differential diagnosis of biliary obstruction with unknown etiology, biliary fascioliasis should be considered in endemic and nonendemic regions. After diagnostic evaluation, endoscopic retrograde cholangiopancreatography (ERCP) was performed for etiological evaluation and/or treatment of biliary obstruction in five patients with a mean age of 55.8 years. Endoscopic sphincterotomy and cholangiogram revealed linear filling defects in the biliary system. Fasciola hepatica parasites were extracted using balloon and basket catheters in two and three patients, respectively. No morbidity or mortality was observed. F. hepatica infection should be considered as a differential diagnosis of biliary obstruction with unknown etiology in endemic and non-endemic regions. ERCP can be the standard diagnostic and/or therapeutic procedure in cases of biliary obstruction due to fascioliasis. Due to slippery and gel-like characteristics of the parasite, use of a basket catheter in semi-opened position may be required in case of unsuccessful extraction using a balloon catheter.

    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, KEMAL
    Objective: 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. Keywords: Laparoscopy, pancreas, oncology
