RESUMO
BACKGROUND: This study was conducted to investigate the serum levels of interleukin-18 (IL-18) in patients with pancreatic adenocarcinoma (PA) and the relationship with tumor progression and known prognostic parameters. METHODS: Thirty-three patients with PA were studied. Serum samples were obtained on first admission before any treatment. Serum IL-18 levels were analyzed using enzyme-linked immunosorbent assay (ELISA). Age- and sex-matched 30 healthy controls were included in the analysis. RESULTS: The median age at diagnosis was 59 years, range 32-84 years; 20 (61%) patients were men and the remaining were women. The median follow-up time was 26.0 weeks (range: 1.0-184.0 weeks). The median overall survival of the whole group was 41.3 ± 8.3 weeks [95% confidence interval (CI) = 25-58 weeks]. The baseline serum IL-18 levels were significantly higher in patients with PA than in the control group (p < 0.001). Serum IL-18 levels were significantly higher in the patients with high erythrocyte sedimentation rate (ESR) and lactate dehydrogenase (LDH) (p = 0.01 and p = 0.05). Moreover, the chemotherapy-(CTx) unresponsive patients had higher serum IL-18 levels compared to CTx-responsive (p = 0.04) subjects. Conversely, serum IL-18 concentration was found to have no prognostic role on survival (p = 0.45). CONCLUSION: Serum levels of IL-18 can be a good diagnostic and predictive marker; especially for predicting the response to gemcitabine based CTx in patients with PA but it has no prognostic role.

Granular cell tumour (GCT), which is a rare benign soft tissue neoplasm, is mostly found in the skin and soft tissue but may develop anywhere in the body. There are less than 10 reported cases of mediastinal GCTs in the current literature. Furthermore, colonic GCTs have recently gained attention due to the increased public awareness on the importance of colonoscopy screening. We report a case of a 52-year-old woman diagnosed incidentally with synchronous GCTs of the mediastinum and the hepatic flexure on her routine screening for post-operative follow-up for status-post right modified radical mastectomy due to a T2N1M0, Stage 2B breast cancer.
RESUMO
Bile duct injuries are among the most dreadful complications of cholecystectomy. As laparoscopic cholecystectomy has become increasingly popular, the incidence of this complication increased and has remained unchanged in spite the learning curve being completed. A 50-year-old female underwent elective laparoscopic cholecystectomy for gallstone disease. A complicated bile duct injury occurred during the procedure. As the injury was immediately recognized, it was treated with concomitant hepaticojejunostomy. In the postoperative period, biliary fistula, which was assumed to be the result of an anastomotic leak, was encountered. Diagnostic and therapeutic percutaneous transhepatic biliary drainage was considered. It revealed that the anastomosis was intact and the source of biliary leak was an aberrant right posterior sectorial branch. A severe bleeding through the biliary catheter occurred due to transmigration of the catheter into the portal vein. Bleeding was controlled with embolization by the interventional radiologist. The patient thereafter was re-operated, and the leakage was sealed by ligation of the aberrant right posterior sectorial branch. The postoperative period was uneventful. As long as cholecystectomy is performed, bile duct injuries will always exist. Therefore, every abdominal surgeon should be aware of possible consequences of complications related to this procedure.
RESUMO
OBJECTIVE: Laparoscopy is gaining more importance in emergency abdominal surgery. Peptic ulcer perforation (PUP) constitutes a significant portion of surgical emergencies. The aim of this study was to evaluate the methods and results of patients who underwent surgery due to PUP in our department. MATERIAL AND METHODS: Patients who were admitted to the hospital in the early period and received Graham-patch (GP) repair due to PUP from January 2009 to January 2013 were divided into two groups as laparoscopic (group L) or open (group O) surgery. Demographic data of the patients, duration of the operation, conversion to open surgery, length of hospital stay, secondary interventions, re-admissions, morbidity and mortality rates were retrospectively evaluated. Patients with conversion to open surgery were included in Group O. RESULTS: Two hundred and nineteen patients were included in the study, 148 of which were in Group O (including the 47 patients with conversion), and 71 in group L. In patients with early admission, the rate of laparoscopically completed GP was 19.6% in the first year of the study, whereas this rate was 61.8% in the fourth year (p<0.001). The rate of conversion to open surgery was 50% in 2009, and 24.4% in 2012 (p=0.028). Length of hospital stay was shorter in group L (p=0.35). The complication rate was 4.2% in patients who had laparoscopic procedures, and was 6.1% in patients who underwent open surgery (p=0.57). Seventy-three percent (n=11) of re-hospitalized patients in the perioperative period (n=15) were treated conservatively. When costs related to secondary interventions and re-hospitalization were included, there was no significant difference between laparoscopic and open surgery groups in terms of cost (p=0.06). CONCLUSION: Laparoscopic surgery for PUP is a reliable method and has been used increasingly over the years in our department. The operative time is longer, the length of hospital stay is shorter, the complication rates are less than open surgery, and the conversion rate is significantly reduced. Laparoscopic GP is feasible in early-admitted patients with PUP, due to the above-mentioned advantages. We believe the rate of conversion to open surgery decreases with increasing experience in laparoscopy.
RESUMO
BACKGROUND: The cornerstone of palliative treatment for inoperable extrahepatic cholangiocarcinoma is the relief of malignant biliary obstruction. The most commonly applied method is endoscopic stenting. However, the procedure can be complicated with stent obstruction. In this respect, endobiliary radiofrequency ablation may serve as an adjunctive tool for prolonging the stent patency. METHODS: Patients who underwent endoscopic retrograde cholangiopancreatography for differential diagnosis and/or palliative treatment after the diagnosis of inoperable extrahepatic cholangiocarcinoma between March 2011 and January 2012 were analyzed. Those in whom endobiliary radiofrequency ablation and endoscopic stenting was successfully performed were included in the study. Technical details of the procedure, duration of stent patency, length of hospital stay, short-term morbidity and mortality rate were documented. RESULTS: Seventeen patients were analyzed, and 10 patients were included in the study. The morbidity and mortality rate within the first 30 days after the procedure was 20% and 0%, respectively. In 2 patients, mild pancreatitis occurred because of the endobiliary procedure. In 1 patient, endobiliary decompression could not be achieved, and therefore, percutaneous transhepatic biliary drainage was carried out. The median duration of stent patency in 9 patients with successful biliary decompression was 9 months (range 6-15). CONCLUSION: Endobiliary radiofrequency ablation seems to be safe and feasible as a palliative measure and may prolong the stent patency and overall survival in patients with malignant biliary obstruction due to inoperable extrahepatic cholangiocarcinoma.

BACKGROUND: In the treatment of a subset of patients with uncomplicated appendicitis, no surgical method has been clearly established as superior. METHODS: The present study was a prospective randomized clinical trial. Patients diagnosed with acute appendicitis were recruited for the study. Patients with a preoperative diagnosis of complicated appendicitis were excluded. The patients were randomly divided into two groups: a laparoscopic appendectomy group and an open appendectomy group. The primary outcome measure was the rate of postoperative septic complications. Secondary outcome measures were the length of hospital stay, postoperative pain score, and quality of life score. RESULTS: Ninety-six patients were included in the study, 50 in the laparoscopic appendectomy group and 46 in the open appendectomy group. There were no significant differences between the two groups in terms of the rates of postoperative septic complications, hospital stay lengths, postoperative pain scores, or quality of life scores. CONCLUSION: The laparoscopic approach to appendectomy in patients with uncomplicated appendicitis does not offer a significant advantage over the open approach in terms of length of hospital stay, postoperative pain score, or quality of life, which are considered the major advantages of minimally invasive surgery.

Solitary necrotic nodule of the liver (SNNL) is a rare benign lesion with uncertain etiology characterized by a "completely necrotic core" and a hyalinized capsule containing elastin fibers (Journal of Clinical Pathology 36:1181-1183, 1983). We report herein a 26-year-old woman with a previous diagnosis of rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's syndrome and no history of malignancy who presented with a complaint of diarrhea of 1-year duration. In the abdominal ultrasound, multiple paraaortic, portocaval, and ileal lymphadenopathies (LAPs) have been found with the largest one being 2 cm in size. The biopsy of the iliac LAP showed reactive nodular hyperplasia. An abdominal CT disclosed an incidental hypoechoic, heterogenous mass sized 27 × 27 mm close to segment VI of the liver. A trucut biopsy of this lesion was made, and clinicopathologic features of the specimen were compatible with a solitary necrotic nodule of the liver. Here, we discuss the diagnosis and the clinical course of this rare entity in light of current literature.
RESUMO
Colorectal cancer is the third most common cancer in Turkey. The current guidelines do not provide sufficient information to cover all aspects of the management of rectal cancer. Although treatment has been standardized in terms of the basic principles of neoadjuvant, surgical, and adjuvant therapy, uncertainties in the management of rectal cancer may lead to significant differences in clinical practice. In order to clarify these uncertainties, a consensus program was constructed with the participation of the physicians from the Acibadem Mehmet Ali Aydinlar and Koç Universities. This program included the physicians from the departments of general surgery, gastroenterology, pathology, radiology, nuclear medicine, medical oncology, radiation oncology, and medical genetics. The gray zones in the management of rectal cancer were determined by reviewing the evidence-based data and current guidelines before the meeting. Topics to be discussed consisted of diagnosis, staging, surgical treatment for the primary disease, use of neoadjuvant and adjuvant treatment, management of recurrent disease, screening, follow-up, and genetic counseling. All those topics were discussed under supervision of a presenter and a chair with active participation of related physicians. The consensus text was structured by centralizing the decisions based on the existing data.

BACKGROUND: Pregnancy-associated acute biliary pancreatitis is a rare but challenging clinical entity in terms of diagnosis and management. We report our institutional medical data of pregnancy-associated acute biliary pancreatitis. METHODS: Medical records of 27 patients admitted to our clinics for pregnancy-associated acute biliary pancreatitis between January 2005 and January 2010 were reviewed. RESULTS: Of the 27 patients, 25 (93%) were in the post-partum period, and 2 (7%) were pregnant. Seventeen patients (63%) were managed with conservative treatment, and were scheduled for interval cholecystectomy, while 10 patients (37%) had early cholecystectomy prior to discharge. The mortality rate was 3% (n=1). CONCLUSION: Pregnancy-associated acute biliary pancreatitis usually has a mild-to-moderate clinical course with a favorable outcome, and can be managed successfully with conservative treatment. Early cholecystectomy done prior to discharge in the initial admission should be considered in mild-to-moderate pregnancy-associated acute biliary pancreatitis, except in patients within the first trimester.

Taenia saginata infestation is one of the most common cestode infestations in humans, that may cause gastrointestinal tract related complications as a result of obstruction, perforation or anastomotic leakage. A 55-year-old male patient who was receiving palliative chemotherapy for stage IV gastric cancer was admitted to the emergency department for abdominal pain. A hollow viscus organ perforation was diagnosed and an emergency surgery was performed. On postoperative day 5, the patient's midline incision eviscerated and a moving taenia emerged, with abundant particulated fluid from the incision line. The patient was admitted for abdominal surgery due to suspected bowel perforation. During the abdominal exploration, a relaxed purse stitch of the feeding tube was observed and no other bowel perforations were seen. The patient underwent two planned surgery for abdominal cavity lavage after the removal of cestode. Unfortunately, the patient died sixteen days after his admission to the intensive care unit. This is the first case describing an extraluminal manifestation of a tapeworm in a midline incision from evisceration without intestinal perforation.

BACKGROUND: The presence of postoperative bile leak is the major outcome measure for the assessment of operative success in partial cystectomy for hydatid liver disease. However, the optimal operative strategy to reduce the postoperative bile leak rate is yet to be defined. METHODS: Medical records of patients who underwent partial cystectomy for hydatid liver disease between January 2013 and January 2015 were reviewed in this retrospective analysis. All patients were managed with a specific operative protocol. The primary outcome measure was the rate of persistent postoperative bile leak. The secondary outcome measures were the morbidity and mortality rate, and the length of hospital stay. RESULTS: Twenty-eight patients were included in the study. Only one patient (3.6 %) developed persistent postoperative bile leak. The overall morbidity and mortality rate was 17.8 and 0 %, respectively. The median length of hospital stay was 5 days. CONCLUSION: Aggressive preventative surgical measures have led to low persistent bile leak rates with low morbidity and mortality.

OBJECTIVE: We assessed the optimal time interval between endoscopic stenting and subsequent surgery in patients with obstructive left-sided colon cancer. METHODS: We reviewed the medical records of patients who underwent endoscopic colonic stenting for obstructive left-sided colon cancer between January 2009 and January 2012. Patients who had successful endoscopic intervention as a bridge to surgery were included in the study. Other variables studied were the duration between endoscopic stenting and surgery, the reobstruction rate, the stoma creation rate, the anastomotic leak rate, and the in-hospital mortality rate. RESULTS: The medical records of 53 patients who underwent endoscopic stenting for obstructive left-sided colon cancer were reviewed, and 43 were included in the study. The median duration between endoscopic stenting and surgery was 7 days (range, 5-33). CONCLUSION: A median duration of 7 to 9 days after endoscopic stenting in patients with obstructive left-sided colon cancer is enough time to subsequently perform a safe surgical procedure. Extending this duration may expose the patient to the risk of reobstruction and emergency surgery.

BACKGROUND: Enhanced recovery pathways are now widely used in elective surgical procedures. The feasibility of enhanced postoperative recovery pathways in emergency surgery for perforated peptic ulcer disease was investigated in this randomized controlled clinical trial. METHODS: Patients with perforated peptic ulcer disease who underwent laparoscopic repair were randomized into 2 groups. Group 1 patients were managed with standard postoperative care and group 2 patients with enhanced postoperative recovery pathways. The primary endpoints were the length of hospital stay and morbidity and mortality. RESULTS: Forty-seven patients were included in the study. There were 26 patients in group 1 and 21 in group 2. There were no significant differences in the morbidity and mortality rates, whereas the length of hospital stay was significantly shorter in group 2. CONCLUSIONS: The application of enhanced postoperative recovery pathways in selected patients with perforated peptic ulcer disease who undergo laparoscopic Graham patch repair seems feasible.

BACKGROUND: Acute appendicitis is the most common surgical non-obstetric pathology during pregnancy. In this report, pregnant patients operated with a diagnosis of acute appendicitis in the last three years are evaluated retrospectively. METHODS: Between January 2009 and January 2011, 20 pregnant patients were operated for acute appendicitis. Patients were evaluated regarding age, gestational age, clinical and laboratory examinations, imaging studies, operative findings, mean hospital stay, mean operative time, and outcome. RESULTS: In 17 of 20 patients, acute appendicitis was confirmed and appendectomy was performed. Ten of the patients were operated with laparoscopic technique and the remaining 10 had open appendectomy. There was no fetal or maternal morbidity or mortality in any patient. All 20 patients delivered healthy babies during the postoperative course. CONCLUSION: Acute appendicitis is a challenging diagnosis in the pregnant patient; however, early surgical intervention should be performed with any suspicion. The type of surgery depends on the surgeon's preference and experience.

BACKGROUND: We aimed to assess the effect of prophylactic injection therapy during the index gastroscopy on upper gastrointestinal bleeding due to Forrest type 2b duodenal ulcer. METHODS: The patients who were admitted with upper gastrointestinal bleeding and who underwent emergency gastroscopy between January 2004 and January 2011 were recruited to the study retrospectively. Among those, the patients with Forrest type 2b duodenal ulcer were selected and divided into two groups. The patients in Group 1 had only diagnostic gastroscopy, whereas those in Group 2 had prophylactic injection therapy during the index gastroscopy. RESULTS: Eighty-seven patients were included in the study. There were 41 patients in Group 1 and 46 patients in Group 2. There was a significant difference in the incidence of rebleeding (26.8% versus 6.5%, p=0.017). The mortality rate was similar in the two groups (9.7% versus 2.1%, p=0.184). CONCLUSION: We recommend prophylactic injection therapy in patients with upper gastrointestinal bleeding who have Forrest type 2b duodenal ulcer.

Endoscopic colonic stenting with self-expanding metallic stents is now widely used to treat malignant large bowel obstruction, where temporary or permanent decompression of the large bowel is desired. The medical records of patients who underwent endoscopic colonic stenting for malignant large bowel obstruction between May 2004 and May 2011 were reviewed. Success rate, morbidity, and mortality rate along with patient characteristics were documented. Sixty-seven patients were included. The procedure was used as a bridge to surgery in 38 and as a palliative measure in 29. Success rate was 95.5 per cent. Perforation and reobstruction occurred in three and three patients, respectively. All of the patients who developed perforation or reobstruction underwent emergency surgery. Endoscopic stenting offers a safe and effective treatment option in patients with malignant large bowel obstruction with comparable outcomes.

PURPOSE: Although spontaneous intramural hematomas of the gastrointestinal tract are very rare, they may be observed with the use of oral anticoagulant, though less frequently in cases of hematological malignancy and other bleeding disorders. Cases diagnosed as spontaneous intramural hematoma have been assessed in our clinic. METHODS: The cases, which were diagnosed as spontaneous intramural hematoma in the gastrointestinal tract (SIHGT) following anamnesis, physical examination, biochemical, radiological and endoscopic findings from July 2008 to July 2012, have been assessed retrospectively. RESULTS: Seven out of 13 cases were women and the mean age was 65.1 years (34 to 82 years). The most frequent complaint on admission was abdominal pain. The most frequent location of SIHGT was the ileum (n = 8). Oral anticoagulant use was the most common cause of etiology (n = 12). In 10 cases, International normalized ratio values were higher than treatment range (2 to 3, where mechanical valve replacement was 2.5 to 3.5) and mean value was 7.6 (1.70 to 23.13). While 12 cases were discharged without problems with medical treatment, one case with acute myeloid leukemia died in the intensive care unit following cerebrovascular attack. CONCLUSION: Spontaneus bleeding and hematomas that may arise in connection with bleeding diathesis may be fatal in cases with long-term oral anticoagulant treatment and insufficient follow-up. In management of these cases, it may be necessary to arrange conservative follow up and/or initialize low molecular weight heparin, and administer vitamin K as well as replace blood products and coagulation factors when indicated.
RESUMO
PURPOSE: The goal of the study was to compare the efficacy of two methods--intracorporeal knotting and metal endoclip application--for closure of the appendiceal stump during laparoscopic appendectomy in a specific group of patients with uncomplicated appendicitis. METHODS: The patients were randomized into two groups who had their appendiceal stump secured by intracorporeal knotting (Group 1) and metal endoclipping (Group 2). Primary outcome measure was postoperative complications, whereas secondary outcome measures were intraoperative complications, operative time, length of hospital stay, and re-admissions (including rehospitalizations and reoperations). RESULTS: One hundred seven patients were prospectively recruited in a randomized study between December 2010 and May 2011. Group 1 and Group 2 included 46 and 61 patients, respectively. The rate of postoperative complications in Group 1 and Group 2 was 8.7% (4/46) and 4.9% (3/61) (P>.05). There were no significant differences between the groups in secondary outcome measures except the mean operative time (61.9 minutes versus 46.3 minutes, P=.0008). CONCLUSIONS: The closure of the appendiceal stump by either intracorporeal knotting or metal endoclipping during laparoscopic appendectomy in uncomplicated appendicitis is safe with comparable morbidity and mortality rates.
