Effect of Genetic Factors on the Etiopathogenesis of Thrombosed Hemorrhoidal Disease.

OBJECTIVE: The aim of this study is to investigate whether genetic factors known to increase thrombosis risk play a role in the etiopathogenesis of thrombosed hemorrhoidal disease. Methods: Genomic DNA from patients with thrombosed hemorrhoidal disease was analyzed for the presence of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T, and methylenetetrahydrofolate reductase A1298C mutations. Results: No significant differences were found in the allele frequencies of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T, and methylenetetrahydrofolate reductase A1298C mutations between patients with thrombosed hemorrhoidal disease and controls (p 0.05). Moreover, there were no significant differences in the genotype (heterozygous and homozygous mutations) of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T and A1298C mutations between patients with thrombosed hemorrhoidal disease and controls (p 0.05). Conclusions: Our findings indicate that mutations associated with venous thromboembolism do not play a role in the etiopathogenesis of thrombosed hemorrhoidal disease; however, several environmental, mechanical, and hemodynamic factors may contribute to the etiopathogenesis of hemorrhoidal disease.

Diagnostic Value of Frozen Section in Patients with Non-Palpable Breast Lesions.

AIM: We analyzed wire-marking, frozen section (FS) and surgical approach in malignancy-suspicious non-palpable lesions detected on mammography (MG) and ultrasonography (US) as breast mass, microcalcifications and distorsions. Material and Methods: A hundred patients in whom wiremarking and frozen section analysis was performed because of non-palpable, malignancy-suspected breast lesions at General Surgery Department, Goztepe Training and Research Hospital, Istanbul were analyzed retrospectively. Results: Seventy-six % of the cases was in BIRADS 4, 21% in BIRADS 3 and 3% BIRADS 5, according to Breast Imaging Reporting and Data System (BIRADS) classification. There was a statistically significant correlation between paraffin block (PB) and frozen section analyses (kappa statistics: 0.872; p 0.01). In BIRADS 4 group of the patients, there was a significant correlation between PB and FS results (Correlation ratio was 85.3% and kappa statistics: 0.853; p 0.01). CONCLUSION: In early stage breast cancer wire-marking and resection method is an important diagnostic tool. In BIRADS 4 patients with non-palpable breast lesions, wire marking, resection under general anesthesia and FS can be used trustfully. In patients with early breast cancer, breast-conserving surgery and sentinel lymphnode biopsy may avoid unnecessary axillary lymph node dissection.

Role of human neutrophil gelatinase associated lipocalin (NGAL) and Matrix Metalloproteinase-9 (MMP-9) overexpression in neoplastic colon polyps.

To explore the role of Human neutrophil gelatinase associated lipocalin (NGAL) and Matrix Metalloproteinase-9 (MMP-9) overexpression in neoplastic polyps and might used as a marker to separate those from non-noeplastic polyps. The study was performed on total 65 cases, 40% (n = 26) of them females and 60% (n = 39) of them males, in Haydarpasa Numune Education and Research Hospital between March 2012 and June 2012. The assessment of immunostained sections was performed by a random principle by one experinced pathologists to the clinico-pathological data. NGAL expression was based on the presence of cytoplasmic and membranous staining. The NGAL intensities of the cases show highly statistically significantly difference according to the pathological results (p < 0.01). The NGAL prevalences of the cases show highly statistically significantly difference according to the pathological results (p < 0.01). The NGAL ID scores of the cases show highly statistically significantly difference according to the pathological results (p < 0.01). We could hypothesize that NGAL and MMP-9 overexpression in neoplastic polyps might be used as a marker to separate those from non-noeplastic polyps. However, in this study, we determined that NGAL overexpression could not distinguish dysplasia from adenocancer. Finally, we suggest NGAL and MMP-9 as an immunohistochemical marker for colonic dysplasia. To determine dysplasia in early steps of colorectal adenoma-carcinoma sequence, it could help to determine new targets in preventive cancer therapy for colorectal cancer. We suggest development of standards for study method, introduction to routine practice by investigating in future studies including many patients.

Long-term effects of forgotten biliary stents: a case series and literature review.

There are many studies about the biliary stents, however there is a little information about the long-term stayed forgotten biliary stents except a few case reports. We have reported the results of a number of cases with biliary stents that were forgotten or omitted by the patient and the endoscopist. During February 2010 to May 2013, five patients were referred to the general surgery clinic of Haydarpasa Numune Training and Research Hospital, Istanbul Turkey. Past history and medical documents submitted by the patient did not indicate a replacement of the biliary stent in 3 patients. Two patients knew that they had biliary stents. We also conducted a literature review via the PubMed and Google Scholar databases of English language studies published until March 2014 on forgotten biliary stent. There were 3 men and 2 women ranging in age from 22 to 68 years (mean age 41.6 years). Patients presented with pain in the upper abdomen, jaundice, fever, abnormal liver function tests or dilatation of the biliary tract alone or in combination. Patients' demographic findings are presented in Table 1. A review of three cases reported in the English medical literature also discussed. The mean duration of the patency of the stent is about 12 months. The biliary stenting is performed either with plastic or metal stents, studies recommending their replacement after 3-6 months. Patients with long stayed forgotten biliary stents are inevitably treated with surgical intervention. We recommend for all endoscopic retrograde cholangiopancreatography units provide a stent registry system that the stents placed for various therapeutic procedures are not forgotten both by the patient as well as the physician. There should be a deadline for biliary stents in the registry system for each patient.

Use of stapling devices for safe cholecystectomy in acute cholecystitis.

Many techniques are described for the ligation of a difficult cystic duct (CD). The aim of this study is to assess the effectiveness and safety of stapling of a difficult CD in acute cholecystitis using Endo-GIA. From January 2008 to June 2012, 1441 patients with cholelithiasis underwent laparoscopic cholecystectomy (LC) at the Department of General Surgery, Haydarpasa Numune Education and Research Hospital. Of these, 19 (0.62%) were identified as having a difficult CD and were ligated using an Endo-GIA stapler. All patients were successfully treated with a laparoscopic approach. The length of hospital stay was 3.4 days. There were umbilical wound infections in 4 patients (21%). The length of follow-up ranged from 1.0 to 50.4 months. In conclusion, Endo-GIA is a safe and easy treatment method for patients with a dilated and difficult CD. The cystic artery should be isolated and ligated if possible before firing the Endo-GIA stapler. If isolation and stapling are not possible, fibrin sealant can be applied to avoid bleeding. The vascular Endo-GIA can be applied in a large CD, but for acute cholecystitis with an edematous CD, the Endo-GIA roticulator 4.8 or 3.5 stapler is preferred.

Analysis of 120 patients with abdominal stab wound focusing on diagnostic role of fast.

OBJECTIVE: The purpose of this study was to evaluate the managemant results of patients with penetrating abdominal injuries. MATERIAL AND METHODS: One hundred twenty (120) patients who were admitted to the Emergency Department of Haydarpasa Numune Training and Research Hospital between December 2003 and December 2010 with abdominal stab wounds were included to retrospective study. The data of all patients regarding age, gender, FAST and CT results, injured organs, surgical procedures, length of hospital stay, follow-up were examined. USG findings were classified as follows: true positive (TP), in cases of positive USG findings, and positive laparotomy; true negative (TN), in cases of negative USG findings, and negative physical examination and follow-up findings; false negative (FN), in cases of negative USG findings, and positive laparotomy; and false positive (FP), in cases of positive USG findings, and negative physical examination and follow-up findings. Abdominopelvic CT extended from the lower chest to the symphysis pubis. CT was performed by administering radiopaque agents via intravenous (i.v.) rectal or oral route. RESULTS: One hundred twenty (120) patients who were admitted to the Emergency Department of Haydarpasa Numune Training and Research Hospital between December 2003 and December 2010 with stab abdominal injuries were hospitalized. According to USG findings, 45.7% were TP, 82.4% were TN, 10.6% were FN, and 34.3% were FP. Thirty-five patients with hemodynamic stability and positive FAST findings and 15 patients with positive hemodynamic stability but negative FAST findings underwent computed tomography. CONCLUSION: Serial FAST and CT help guide treatment for stable patients with penetrating sharp injuries to the abdomen.

Asymptomatic partial splenic infarction in laparoscopic floppy Nissen fundoplication and brief literature review.

Short gastric vessels are divided during the laparoscopic Nissen fundoplication resulting in splenic infarct in some cases. We report a case of laparoscopic floppy Nissen fundoplication with splenic infarct that was recognized during the procedure and provide a brief literature review. The patient underwent a laparoscopic floppy Nissen fundoplication. We observed a partial infarction of the spleen. She reported no pain. A follow-up computed tomography scan showed an infarct, and a 3-month abdominal ultrasound showed complete resolution. Peripheral splenic arterial branches have very little collateral circulation. When these vessels are occluded or injured, an area of infarction will occur immediately. Management strategies included a trial of conservative management and splenectomy for persistent symptoms or complications resulting from splenic infarct. In conclusion, we believe that the real incidence is probably much higher because many cases of SI may have gone undiagnosed during or following an operation, because some patients are asymptomatic. We propose to check spleen carefully for the possibility of splenic infarct.

An unusual presentation of perforated appendicitis in epigastric region.

INTRODUCTION: Atypical presentations of appendix have been reported including backache, left lower quadrant pain and groin pain from a strangulated femoral hernia containing the appendix. We report a case presenting an epigastric pain that was diagnosed after computed tomography as a perforated appendicitis on intestinal malrotation. PRESENTATION OF CASE: A 27-year-old man was admitted with a three-day history of epigastric pain. Physical examination revealed tenderness and defense on palpation of epigastric region. There was a left subcostal incision with the history of diaphragmatic hernia repair when the patient was 3 days old. He had an intestinal malrotation with the cecum fixed at the epigastric region and the inflamed appendix extending beside the left lobe of liver. DISCUSSION: While appendicitis is the most common abdominal disease requiring surgical intervention seen in the emergency room setting, intestinal malrotation is relatively uncommon. When patients with asymptomatic undiagnosed gastrointestinal malrotation clinically present with abdominal pain, accurate diagnosis and definitive therapy may be delayed, possibly increasing the risk of morbidity and mortality. CONCLUSION: Atypical presentations of acute appendicitis should be kept in mind in patients with abdominal pain in emergency room especially in patients with previous childhood operation for diaphragmatic hernia.

A modified Rendezvous ERCP technique in duodenal diverticulum.

AIM: To postoperative endoscopic retrograde cholangiopancreatography (ERCP) failure, we describe a modified Rendezvous technique for an ERCP in patients operated on for common bile duct stone (CBDS) having a T-tube with retained CBDSs. METHODS: Five cases operated on for CBDSs and having retained stones with a T-tube were referred from other hospitals located in or around Istanbul city to the ERCP unit at the Haydarpasa Numune Education and Research Hospital. Under sedation anesthesia, a sterile guide-wire was inserted via the T-tube into the common bile duct (CBD) then to the papilla. A guide-wire was held by a loop snare and removed through the mouth. The guide-wire was inserted into the sphincterotome via the duodenoscope from the tip to the handle. The duodenoscope was inserted down to the duodenum with a sphincterotome and a guide-wire in the working channel. With the guidance of a guide-wire, the ERCP and sphincterotomy were successfully performed, the guide-wire was removed from the T-tube, the stones were removed and the CBD was reexamined for retained stones by contrast. RESULTS: An ERCP can be used either preoperatively or postoperatively. Although the success rate in an isolated ERCP treatment ranges from up to 87%-97%, 5%-10% of the patients require two or more ERCP treatments. If a secondary ERCP fails, the clinicians must be ready for a laparoscopic or open exploration. A duodenal diverticulum is one of the most common failures in an ERCP, especially in patients with an intradiverticular papilla. For this small group of patients, an antegrade cannulation via a T-tube can improve the success rate up to nearly 100%. CONCLUSION: The modified Rendezvous technique is a very easy method and increases the success of postoperative ERCP, especially in patients with large duodenal diverticula and with intradiverticular papilla.

Treatment of ampullary neuroendocrine tumor by endoscopic snare papillectomy.

PATIENT: Female, 45 FINAL DIAGNOSIS: Neuroendocrine tumor Symptoms: Abdominal pain Medication: - Clinical Procedure: - Specialty: Gastroenterology and Hepatology. OBJECTIVE: Unusual setting of medical care. BACKGROUND: Neuroendocrine tumor of the ampulla of Vater is extremely rare and is generally a low-grade endocrine cell tumor. The merits of radical vs. local resection remain uncertain. CASE REPORT: A 45-year-old female patient presented with abdominal pain lasting for 2 months. Papilla that was tumor-like macroscopically was seen in the second part of the duodenum in endoscopic retrograde cholangiopancreatography. Biopsy was histologically confirmed as a low-grade neuroendocrine tumor. No lymphadenopathy or visceral metastasis was found on an abdominal CT scan, In-111 octreotide scan, and EUS. The ampulla was removed by endoscopic snare papillectomy. All margins of resection were negative for tumor. CONCLUSIONS: Endoscopic snare papillectomy may be the first step in the management of neuroendocrine tumors of the ampulla of Vater in high-risk surgical candidates and selected patients such as those with a well differentiated, low-grade, small tumor without regional/ distant metastasis. However, it can also be used in younger patients who wish to avoid surgical resection.

Surgical approach to splenic hydatid cyst: single center experience.

The benefits and risks of surgery for splenic hydatid cyst (SHC) remain controversial. We aimed to share our experience about a surgical approach for SHC. Sixteen consecutive patients with SHC disease who underwent open splenectomy at our hospital between January 2006 and July 2012 were retrospectively evaluated. Data on the patients' demographic features, clinical findings, radiological and serological diagnostic methods, and surgical and medicinal treatment options were collected and used to generate descriptive profiles of diagnosis, treatment course, and outcome. The patient population was composed of 6 females and 10 males, with an age range of 18 to 79 years (mean age: 47.0 ± 18.0). Radiological examinations detected hydatid cysts in spleen alone (n = 7) or both spleen and liver (n = 9). Preoperative serological testing identified 13 of the patients as IHA positive. All except 1 patient received a 10- to 21-day preoperative course of albendazole therapy and all patients received vaccination 1 week prior to surgery. Seven patients underwent splenectomy. The remaining patients underwent splenectomy with partial cystectomy and omentopexy (n = 6), partial cystectomy and unroofing (n = 1), pericystectomy (n = 1), or pericystectomy with partial nephrectomy (n = 1). All except one patient received a 10- to 45-day postoperative course of albendazole. No patients developed serious complications or signs of recurrence during the follow-up. The clinical profile of SHC disease at our hospital includes diagnosis by radiological methods, splenectomy treatment by simple or concomitant procedures according to the patient's symptoms, cyst size, number and localization, and compression of adjacent organs, and adjunct vaccination to decrease risk of postoperative septic complications. This profile is associated with low risk of complications and high therapeutic efficacy.

Karydakis flap procedure in patients with sacrococcygeal pilonidal sinus disease: experience of a single centre in Istanbul.

BACKGROUND: The aim of this retrospective study was to evaluate the results of patients with sacrococcygeal pilonidal sinus who underwent surgery using the Karydakis technique. METHODS: Two hundred fifty-seven patients with sacrococcygeal pilonidal sinus disease were treated by the Karydakis flap procedure between December 2003 and June 2011. Patients were evaluated with respect to age, gender, preoperative symptoms, duration of preoperative symptoms, history of pilonidal sinus surgery, early postoperative complications, recurrence rates, and cosmetic satisfaction. RESULTS: There were 223 (86.8%) male and 34 (13.2%) female patients. The mean age of the patients was 27.15 ± 7.69 years. The most frequent symptom was seropurulent discharge (57.58%). Postoperative morbidity was noted in 24 patients (9.3%). The mean hospital length of stay was 3.34 ± 1.42 days. The cosmetic satisfaction rate was 91.06%. Recurrences were noted in 6 patients (2.3%). CONCLUSION: The Karydakis flap procedure is a safe treatment alternative for the surgical treatment of sacrococcygeal pilonidal sinus disease owing to the associated low complication rate, short hospital length of stay, rapid healing, and a high patient satisfaction rate.

Symptom-histopathology relation in upper GI endoscopy.

OBJECTIVE: The purpose of this article is to examine the correlation between information obtained from patients before endoscopy and histopathological findings. MATERIAL AND METHODS: One thousand, five hundred and thirty-six patients underwent upper GI endoscopy between January 2011-September 2012, without distinction of age and sex were included in the study. Patients with alarm symptoms, dyspepsia, epigastric pain, gastroesophageal reflux were recorded. Tissue samples taken for histopathological examination and H. pylori screening were evaluated by Giemsa stain. The information given by the patients and histopathological findings were comparatively evaluated. RESULTS: Six hundred and twenty-four patients (40.6%) were male and 912 (59.4%) were female. Mean age was 45 years (18-90). H. pylori was positive in 416 patients with dyspepsia (58.8%), 172 patients with epigastric pain (54.4%), 52 patients with GER symptoms (28.3%) and 128 patients with alarm symptoms (50.8%). Four patients with dyspepsia (0.6%) and 20 patients with alarm symptoms (7.9%) were diagnosed with stomach cancer. CONCLUSION: The main factor should be considered as the presence of at least one of the alarm symptoms when planning an upper GI endoscopy in a patient. In the presence of at least one of the alarm symptoms, an upper GI endoscopy should be performed regardless of age. Under the age of 50 and for patients without alarm symptoms, medical treatment can be tried before performing upper GI endoscopy. Patients with GER symptoms but not diagnosed as reflux esophagitis, should be treated long-term even when symptoms decline with initial treatment.
