    Abstract Endoscopy is being frequently performed for both diagnostic and therapeutic applications in surgical practice. Surgery, as a scientific area, has an important role in the propagation of therapeutic endoscopic procedures. The contribution of surgeons to the evolution of endoscopic applications and its practice is a triggering factor for the improvement of endoscopic instruments and their widespread use. Training and education on basic diagnostic and therapeutic surgical endoscopy should be implemented as part of general surgery residency core program, according to accepted standardized criteria, in order for general surgeons to perform endoscopic applications in the future. In light of this information, it can be concluded that endoscopy training and skills should be standardized within accepted general principles. Standards to be used during post-graduate endoscopic practice should be precisely stated. In addition to accreditation of both surgeons and endoscopic centers, theoretical and practical education programs should be composed and organized.

    Abstract Pancreatic head adenocarcinoma (PHAC) is one of the most aggressive malignancies, and it has low long-term survival rates. Surgery is the only option for long-term survival. The difficulties associated with PHAC include higher frequencies of regional or distant lymph node metastases and vascular involvement, and positive resection margins in pancreatic and retroperitoneal tissues. Radical resections increase margin negativity and life expectancy; however, the extend of the surgery applied is controversial. Thus, western and eastern centers may use different approaches. Multiorgan, peripancreatic nerve plexus, and vascular resections have been discussed in relation to radical surgery for pancreatic cancer as have the roles of neoadjuvant and adjuvant therapy regimens. Determining the appropriate limits for surgery, standardizing definitions and surgical techniques according to guidelines, and centralizing pancreatic surgery within high-volume institutions to reduce mortality and morbidity rates are among the most important issues to consider. In this review, we evaluate the basic concepts underlying and the roles of radical surgery for PHAC, and lymphadenectomy, nerve plexus, retroperitoneal tissue, vascular, and multivisceral resections, total pancreatectomy, and liver metastases are discussed.

    Abstract Most cases of hepatic hydatid disease exhibit uncomplicated clinical course and management. However, the diagnosis and management of complicated hepatic hydatid disease is a special issue. One of the most common and serious complications of hepatic hydatid disease is the rupture of the cyst into intrahepatic bile ducts. The clinical appearance of intrabiliary rupture can range from asymptomatic to jaundice, cholecystitis, cholangitis, liver abscess, pancreatitis and septicemia. Current treatments for major ruptures can result in high morbidity and mortality rates. Furthermore, ruptures that cannot be diagnosed preoperatively can induce complications such as biliary fistulae, biloma, cavitary infection and obstructive jaundice. In the past, these complications were diagnosed and treated by surgical methods. Currently, complications in both the pre- and postoperative periods are diagnosed and treated by non-invasive or minimally invasive methods. In clinical practice, endoscopic retrograde cholangiopancreatography (ERCP) is indicated for patients with preoperative frank intrabiliary rupture in which hydatid elements are clearly seen in the bile ducts, or for biliary adverse events after surgery, including persistent biliary fistulae and jaundice. However, controversy concerning routine preoperative ERCP and prophylactic endoscopic sphincterotomy in patients suspected of having minor cystobiliary communications still remains. In this article, the role of ERCP in the diagnosis and management of hepatic hydatid disease during the pre- and postoperative periods is reviewed.

    Abstract Background: Celiac artery stenosis (CAS) is a not a rare finding in the general population. The median arcuate ligament (MAL) is a fibrous arch that unites the diaphragmatic crura on either side of the aortic hiatus and, while it normally passes cranial to the origin of the celiac truncus, a low-lying ligament may lead to compression of the celiac artery and is the one of the major causes of CAS.
    Case report: In this paper, we present a patient with a mass in the gastric bulbus who was diagnosed with celiac artery stenosis during the pancreaticoduodenectomy (PD). MAL was the cause of the celiac artery stenosis, determined based on the findings of preoperative computed tomography (CT).
    Conclusion: Although CAS is usually asymptomatic due to the collateral blood supply, it may be associated with potentially disastrous results due to ischemia of the upper abdominal organs as a result of disruption of the collateral pathways. It is especially important to recognize the presence of CAS and its etiology before interventional procedures. With the increasing use of multidetector computed tomography (MDCT), it becomes essential for radiologists to be aware of this entity and the cross-sectional findings.

    Abstract 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.

    Abstract 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.

    Abstract Introduction: Hydatidosis is a zoonotic infection and treatment is mandatory to avoid complications. Surgery remains the first 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. The length of hospital stay was 3.4 days in Group 1 and 4.7 days in Group 2 (p=0,007). The 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). Three 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 difficulty.

    Abstract Background/aims: ERCP and endoscopic sphincterotomy in patients with Billroth II gastrectomy are technically more difficult due to the reversed anatomy. We developed a new guidewire sphincterotome that includes two 15-mm non-isolated metal parts, one of which is located 12 cm from the distal tip and the other in the proximal end. The aim of this study was to evaluate the feasibility of and outcomes with the new sphincterotome for sphincterotomy in patients with Billroth II gastrectomy.
    Methods: Between January 2004 and March 2007, 11 patients with Billroth II gastrectomy underwent endoscopic sphincterotomy with the new guidewire sphincterotome. Procedures were initiated by deep cannulation of the bile duct with a standard catheter and guidewire sphincterotome. After cholangiography, the catheter was withdrawn with 0.5 to 1 cm of its tip outside the duodenoscope. The distal non-isolated part of the sphincterotome was placed in the papillary orifice. In order to reach the proper position, the duodenoscope's elevator was moved to the downward position, the up-down dial was turned slightly in the downward direction, and then the duodenoscope was pushed slightly forward. Finally, sphincterotomy was performed in the 6 o'clock direction.
    Results: Sphincterotomy with the new sphincterotome was successfully achieved in all patients without using protective pancreatic stents. Seven patients had common bile duct stones, two pancreatitis, one odditis, and another one persistent bile duct leakage. There were no sphincterotomyrelated complications or death during this study.
    Conclusions: In this pilot study, endoscopic sphincterotomy with a new guidewire sphincterotome in patients with Billroth II gastrectomy was found to be clinically successful, concise, easy to perform, efficient, and reliable. However, further large comparative studies are needed for a definite conclusion.

    Abstract Although vaginal reconstructions with intestinal segments require particularly complex surgical procedures, this technique has become popular with respect to fairly good functional and esthetic outcomes. This study describes cases of vaginal reconstruction performed using a modified rectosigmoid colon held in an ischemic state in order to reduce secretion and denervated in order to prevent defecation problems. Vaginal reconstructions with rectosigmoid colon were performed on 43 patients. In this retrospective study, 34 patients had Müllerian agenesis, while nine had undergone male to female sex reassignment surgery in which adequate vaginal depth had not been achieved. A rectosigmoid colon with its vascular pedicle was used and left in an ischemic state. All nerve structures within the pedicle were excised intraoperatively. Follow-up period was between 12 and 60 months. Partial necrosis occurred in one patient which was reconstructed with local flap. Hematoma developed beneath the skin incision in two cases, but resolved with conservative treatment. A good esthetic outcome was achieved in all cases. Sexual function was assessed using the Female Sexual Function Index (FSFI) in 15 patients. Fourteen out of 15 patients scored above 26.5 on this scale and were determined as having no sexual dysfunction (FSFI score ≥26.5). In conclusion, vaginal reconstruction with denervated rectosigmoid held in an ischemic state appears to be a reasonable option among several available reconstruction techniques.
