Prognostic importance of molecular-like classification in gastroesophageal junction tumors (Izmir Oncology Group [IZOG] study).

A comprehensive molecular classification was published in 2014 within The Cancer Genome Atlas (TCGA) to guide clinical approaches and treatment strategies. This study aimed to investigate the clinicopathological and prognostic importance of the classification using immunohistochemistry (IHC) and chromogenic in situ hybridization (CISH) to identify potential surrogate markers of molecular changes in gastroesophageal junction (GEJ) adenocarcinomas. A total of 52 GEJ adenocarcinomas were divided into five groups using IHC with MLH-1, E-cadherin, p53 and CISH with EBER: 1) microsatellite unstable (MSI: negative with MLH-1), 2) genomically stable tumors (GS: positive with p53), 3) chromosomally unstable tumors (CUN: negative with e-cadherin), 4) EBV+ tumors (EBV+: positive with EBER) and 5) unclassifiable (G-NOS: MLH-1 and e-cadherin positive with p53 and negative with EBER). The largest group consisted of 24 (46.2%) cases of CUN tumors. This group was followed by groups of GS with 14 (26.9%) cases, MSI with 7 (13.5%) cases, and EBV + with 3 (5.8%) cases, respectively. Although this classification was not associated with pathological features, it was found to be closely related to prognosis (p = 0.029). Patients with EBV+ tumors had the longest overall survival, followed by the G-NOS, MSI, CUN, GS groups.

Gastric duplication cyst in adult: Challenge for surgeons.

Gastric duplication cysts (GDCs) are uncommon developmental anomalies found primarily in children, being rarely seen in adults. Duplications can occur anywhere in the intestinal tract from the mouth to the anus. Accurate diagnosis of cysts before resection is difficult even using the most advanced imaging techniques. In this report, we present and discuss a case of GDC in a 25-year-old man treated laparoscopically. Patient admitted to our department with complaints of epigastric pain and swelling. Magnetic resonance imaging performed for accurate characterisation showed a 4 cm × 4.5 cm cystic lesion, with heterogeneous signal intensity on T2-weighted images, located in the posterior wall of the stomach. Pre-operative differential diagnosis including gastrointestinal stromal tumour (GIST) was made according to radiological findings. Patient underwent surgery and cyst resected laparoscopically. Histopathological examination suggesting duplication cyst. GDC can easily be mistaken for a GIST, and the clinician as well as radiologist must maintain a high degree of suspicion.

Recurrent pilonidal disease surgery: Is it second primary or reoperative surgery?

OBJECTIVE: Pilonidal sinus disease (PSD) effects mainly young men's social and work life with frequent recurrence rate. Reoperation for unimproved or recurrent disease is somehow troublesome. Surgeons may think that changing treatment strategy after recurrence may prevent further relapses of PSD. We analyzed patients with recurrent pilonidal sinus to determine their predisposing features for recurrence and the outcomes of the preferred surgical methods. MATERIAL AND METHODS: From 2007 to 2012, out of 95 recurrent pilonidal sinus disease (rPSD) patients, 62 operated cases were included and examined retrospectively. Their retrospective data were examined for demographics, 1(st) and 2(nd) operation types, patient satisfaction and pain scores. For cases with insufficient preoperative or postoperative data, phone call and interviews were done to obtain data. Some were kindly invited to the outpatient examination. Student's t test, Mann-Whitney U test, and Kaplan Meier test for disease free survival time were used where appropriate. P values less than 0.05 were accepted to be statistically significant. RESULTS: Total of 62 rPSD patients were examined. Male:female ratio was 2.9:1. The mean age after 1(st) and 2(nd) operations were 24.7 and 28.1 years, respectively. One and five-year recurrence rates were 33.9% and 66.1%, respectively. The mean interval between the 1(st) and 2(nd) operations was 45.6 months. Excision and midline closure was the most frequent type of operation followed by flap reconstructions and excision-lay open procedures. The 1(st) operation types of rPSD cases were different from that of 2(nd) operations. Pain perception and satisfaction scores were better in flap reconstruction groups. CONCLUSION: Reoperative surgery of rPSD is satisfactory with certain precautions. Relapses after flap reconstruction procedures with a well-being period should be referred as second primary disease. Changing surgical strategy is not always indicated as some patients with recurrence have relapsing or second primary disease that have distinct clinical course. Re-flap surgery after any kind of relapse is well appreciated.

Characteristics of Emergency Gastrointestinal Stromal Tumor (GIST).

BACKGROUND/AIMS: Gastrointestinal Stromal Tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract (GIT). Importance of GISTs is increasing while surgeons are facing with more frequent either in emergency setting of elective cases. Delineating the presentation and management of emergency GIST is important. METHODOLOGY: From 2005 to 2014, emergency cases with final diagnosis of GIST were examined retrospectively. Total of 13 operated cases were evaluated by patients characteristics, clinical presentation, operational findings and postoperative prognosis. RESULTS: There were 9 male and 4 female with the mean age of 48.15 years. The most frequent presentations are ileus and GIT hemorrhage both covering the 84% of patients. Small bowel was the dominating site with ileus. Stomach was the second frequent site of the disease with the finding of hemorrhage. CONCLUSION: Emergency patients are more likely to come with small bowel GIST and obstruction symptoms. Hemorrhage is the most frequent symptom for emergency GIST of stomach and duodenum.

Evaluation of factors affecting mortality in Fournier's Gangrene: Retrospective clinical study of sixteen cases.

OBJECTIVE: Fournier's gangrene is a progressive, necrotizing fasciitis due to synergistic infection of the perineum and external genitalia that is associated with high mortality and morbidity. The purpose of this study is to review the diagnostic and treatment methods that effect mortality in Fournier's gangrene. MATERIAL AND METHODS: Sixteen patients who were diagnosed and treated at our clinic between 2011 and 2013 due to Fournier's gangrene were retrospectively analyzed. The surviving and non-surviving patient groups were compared in terms of age, sex, onset time of symptoms, isolated microorganisms, concomitant diseases, Fournier's gangrene severity index (FGSI), and length of hospital stay. RESULTS: Ten of our cases (62.5%) were male and six (37.5%) were female, with a mean age of 61.2±12.3 (42-73) years. The mortality rate was 18.8% (3 cases). The mean duration of symptoms before admission was 4.31±1.81 (2-8) days. This period was 6.67±1.52 days in patients who succumbed to death, and 3.77±1.42 days in patients who survived (p=0.007). Ten cases (62.5%) had concomitant diabetes mellitus. The most common organism isolated in wound cultures was Escherichia coli (68.7%), and Acinetobacter baumannii, Proteus mirabilis, methicillin-resistant Staphylococcus aureus and Enterococcus spp. in the remaining patients. The mean FGSI of surviving patients was 3.84±1.77, and 7.66±0.57 in fatal cases (p=0.003). The mean length of hospital stay was 25.5 days (2-57) and duration of hospitalization was significantly longer in survivors (p<0.05). CONCLUSION: The delay in diagnosis and higher FGSI may be responsible for worsening of prognosis and mortality in Fournier's gangrene. Early diagnosis and determination of the severity of the disease, aggressive surgical debridement and appropriate antimicrobial therapy may improve prognosis.

Diagnosis and treatment of solid pseudopapillary tumor of the pancreas: experience of one single institution from Turkey.

BACKGROUND: Solid pseudopapillary neoplasia (SPN) of the pancreas is an extremely rare epithelial tumor of low malignant potential. SPN accounts for less than 1% to 2% of exocrine pancreatic tumors. The aim of this study is to report our experience with SPN of the pancreas. It includes a summary of the current literature to provide a reference for the management of this rare clinical entity. METHODS: A retrospective analysis was performed of all patients diagnosed and treated for SPN in our hospital over the past 15 years (1998 to 2013). A database of the characteristics of these patients was developed, including age, gender, tumor location and size, treatment, and histopathological and immunohistochemical features. RESULTS: During this time period, 255 patients with pancreatic malignancy (which does not include ampulla vateri, distal choledocal and duodenal tumor) were admitted to our department, only 10 of whom were diagnosed as having SPN (2.5%). Nine patients were women (90%) and one patient was a man (10%). Their median age was 38.8 years (range 18 to 71). The most common symptoms were abdominal pain and dullness. Seven patients (70%) presented with abdominal pain or abdominal dullness and three patient (30%) were asymptomatic with the diagnosis made by an incidental finding on routine examination. Abdominal computed tomography and/or magnetic resonance imaging showed the typical features of solid pseudopapillary neoplasm in six (60%) of the patients. Four patients underwent distal pancreatectomy with splenectomy, one patient underwent a total mass excision, and one patient underwent total pancreatic resection. Two required extended distal pancreatectomy with splenectomy. Two underwent spleen-preserving distal pancreatectomy. CONCLUSIONS: SPN is a rare neoplasm that primarily affects young women. The prognosis is favorable even in the presence of distant metastasis. Although surgical resection is generally curative, a close follow-up is advised in order to diagnose a local recurrence or distant metastasis and choose the proper therapeutic option for the patient.

A rare cause of acute abdomen: Splenic hematoma and rupture resulting from pancreatitis.

Splenic subcapsular hematoma and splenic rupture due to pancreatitis are rare causes of acute abdomen. Here we report a case of splenic hematoma and rupture resulting from a second attack of pancreatitis in a 38 year-old woman with chronic pancreatitis due to alcoholism. Her first pancreatitis attack, 4 months before the second, was complicated with a pancreatic pseudocyst that was drained and acute renal failure. The patient underwent pancreatic necrosectomy and splenectomy, and was discharged on the sixth postoperative day without any further complication. We conclude that splenic hematoma, a complication of pancreatitis attack, which may require emergency surgical intervention, must be kept in mind in order to make an early diagnosis. Considering a possible subsequent attack of pancreatitis and determining follow-up criteria, radical treatment must be planned immediately.

Prognostic significance of immunhistochemical axl expression in pancreas ductal adenocarcinomas.

Introduction and Aim: Pancreas Ductal Adenocarcinomas (PDACs) are among the leading causes of cancer-related death. Tyrosine kinase receptors (TKRs) are responsible for cell plasticity, chemoresistance, immunosuppression and metastasis potential. Axl is a receptor of the TKR family, and it has come to the fore in cancer treatment in the last decade. This study aimed to investigate the relationship of immunohistochemical Axl expression with histological features and its prognostic importance in PDACs. Materials and Methods: Fifty-three patients who were operated on for PDAC between 2006-2017 were evaluated retrospectively. Features of tumors; size, lymphovascular invasion (LVI), perineural invasion (PNI), resection margin (RM), lymph node metastasis (LNM), differentiation, tumor-infiltrating lymphocyte, stage and overall survival were recorded. Immunohistochemically, membranous and or cytoplasmic staining was considered positive for Axl. Statistically, Pearson Chi-Square, Cox regression and Kaplan Mayer tests were used in the SPSS 21.0 program. Results: Axl was positive in 28 patients (52.8%). Axl positivity was found to be associated with the presence of LVI (P = 0.009) and LNM (P = 0.002) and was an independent prognostic factor in short survival (P = 0.006). Conclusion: It was found that increased expression of Axl, which is known to increase EMT-mediated metastasis in carcinogenesis, may be an indicator of local spread and poor prognosis in PDAC patients. In this respect, it can be promising as a targeted molecule in PDAC patient's individualized treatments.

Xanthogranulomatous pancreatitis treated by duodenum-preserving pancreatic head resection.

BACKGROUND: Xanthogranulomatosis is an idiopathic, rare process in which lipid-laden histiocytes are deposited at various locations in the body. We present two cases who were treated by duodenum-preserving pancreatic head resection and eventually diagnosed as having xanthogranulomatous pancreatitis. METHODS: A 30-year-old caucasian man was admitted to our clinic for vague abdominal pain and epigastric dullness. Magnetic resonance cholangiopancreatography and endoscopic retrograde pancreatography suggested the existence of chronic pancreatitis. Another 34-year-old caucasian woman was admitted to our clinic because of right upper quadrant pain. Magnetic resonance cholangiopancreatography demonstrated a dilatation and stone of the main pancreatic duct. Based on a diagnosis of chronic pancreatitis, pancreatic head resection was planned and a laparotomy was performed in both of cases. RESULTS: In both cases, duodenum-preserving pancreatic head resection was performed. Macroscopic and microscopic findings revealed xanthogranulomatous inflammation, which led to a diagnosis of xanthogranulomatous pancreatitis. CONCLUSION: Although this type of pancreatitis is extremely rare, it is important to keep it in mind for a differential diagnosis because it may simulate chronic pancreatitis or a malignant tumor on imaging.

A rare cause of acute abdomen: small bowel obstruction due to phytobezoar.

BACKGROUND: Phytobezoars are a rare cause of acute small bowel obstruction. The aim of this work was to identify the diagnostic difficulties and treatment of this rare entity. METHODS: Data of 14 patients operated between January 1999-January 2009 with small bowel phytobezoar were retrospectively studied. The patients (n=432) were treated in our clinic for small bowel obstructions. Of these, 14 (3.2%) phytobezoar-induced small bowel obstructions were included in this series. Median patient age was 57.25 years; nine (64%) of the patients were male, and five (36%) were female. RESULTS: The predisposing factor was previous gastric surgery in 12 (87.5%) patients and previous abdominal surgery and total absence of the teeth in two (14.3%) patients. A completely obstructing terminal ileal phytobezoar was found in nine (64%) patients and jejunal phytobezoar in five (36%) patients during exploration. There was no mortality. CONCLUSION: Phytobezoar-induced small bowel obstruction remains an uncommon diagnosis that poses a diagnostic and management challenge. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery, poor dentition or a history suggestive of increased fiber intake.

Gallstone ileus as an unexpected complication of cholelithiasis: diagnostic difficulties and treatment.

BACKGROUND: Gallstone ileus is a rare complication of cholelithiasis, mostly in the elderly. The aim of this study was to evaluate our experience with 12 gallstone ileus cases and discuss current opinion as reported in the literature. METHODS: Data of 12 patients operated between January 1998 and January 2008 with gallstone ileus were retrospectively studied. RESULTS: There were 12 cases (9 F, 75%; 3 M, 25%) with a mean age of 63.6 (50-80) years. Median duration of symptoms before admission to the hospital was 4.1 (1-15) days. Preoperative diagnosis was made in only five cases (41.6%). Enterolithotomy was done in nine cases (75%). Enterolithotomy and resection of the small intestine--required for decubital necrosis from the gallstone--was performed in one case (8.3%). In one case (8.3%), enterolithotomy was completed in one stage with cholecystectomy and closure of the fistula during acute surgery, and in another case (8.3%), enterolithotomy + primary suturing of the jejunal perforation was performed. There were two (16.6%) perioperative mortalities. CONCLUSION: Gallstone ileus remains a diagnostic challenge despite advances in imaging techniques, and pre-operative diagnosis is often delayed. Gallstone ileus should be suspected in all cases admitted to the emergency service with acute intestinal obstruction with a history of cholelithiasis, especially in the elderly and females.

Comparison of ePTFE graft repair with primary suturing in an experimental duodenal perforation model in rats.

BACKGROUND: In this experimental study, we treated peptic ulcer perforation in the first portion of the duodenum using an ePTFE (expanded polytetrafluoroethylene) soft tissue graft and compared results with primary suturing. METHODS: Wistar Albino rats were randomized into two groups. A duodenal defect of 3 mm was created in the first portion of the duodenum in all 24 rats. Macroscopic evaluation was done to determine presence of intraabdominal leakage, peritonitis, intraabdominal adhesions, and the level of adhesion, if present. The adhesion severity scoring system was used to score severity of adhesions. Histology section score criteria were used for scoring in microscopic evaluation. RESULTS: There was no statistically significant difference between the two groups in the adhesion severity scoring according to grades. However, when overall scoring was considered, a statistically significant difference was determined between the two groups (p=0.045). According to microscopic examination, there was no statistically significant difference between the two groups when classified into none to minimal cell accumulation, thin immature granulations and moderately thick granulation (p=0.089, p=0.178, p=0.755); however, there was a statistically significant difference between the two groups in the thick vascular granulation class (p=0.005). CONCLUSION: Use of the ePTFE graft method is easy, and results are comparable to those achieved with primary suturing. However, our results need further confirmation with larger series in animals and also with human studies.

Anaplastic Carcinoma of the Pancreas: A Rare Clinical Entity.

Anaplastic carcinoma of the pancreas (ACP) is a very rare histologic subtype of pancreatic cancer and associated with more aggressive and poor prognosis than pancreatic ductal adenocarcinoma. We aimed to review this rare entity and discuss its clinical features, diagnosis and therapy. We presented a case of a 63-year-old male patient that diagnosed as ACP with cyst formation at a tertiary medical center with a detailed review of the current medical literature. We performed pancreaticoduodenectomy operation with lymph node dissection after diagnosis. Any complication after surgery was not observed. Anaplastic pancreas carcinomas are associated with poor survival when compared to invasive ductal adenocarcinomas. Clinical, radiological, laboratory and histological features may be helpful in making differential diagnosis and should be kept in mind in the diagnosis of this rare pancreatic malignancy.

How much Reliable Is Alvarado Scoring System in Reducing Negative Appendectomy?

There is still an ongoing debate, especially regarding early diagnosis of acute appendicitis. Early surgery leads to inadequate evaluation of acute abdominal pain and negative appendectomy, whereas delayed surgery leads to appendicitis perforation complications. The diagnosis of this condition is considerably difficult, especially due to subtle early symptoms and clinical condition. The aim of the present study was to identify whether the Alvarado scoring system could reduce the incidence of negative appendectomy in patients who will undergo surgery for acute appendicitis. Patients who underwent surgery with acute appendicitis prediagnosis were retrospectively classified as negative appendectomies (group A) and positive appendectomies (group B) according to histological diagnosis. All groups were evaluated for age, gender, Alvarado scores, and parameters. Two hundred eighty-one patients were included in the study. Group A contained 71 (25.3 %) patients, and group B contained 210 (74.7 %) patients. There was a significant difference in WBC, left shift, rebound, and change of pain localization between the groups (p = 0.002, p < 0.001, p < 0.001, and p = 0.023, respectively). Alvarado scores were significantly different between the groups (p < 0.001). In logistic model examination, the major factor was the Alvarado score (7 or above) and the minor factor was spreading pain. The Alvarado scoring system can be used to reduce negative appendectomy in patients who will undergo surgery with acute appendicitis.

Negative-pressure Wound Therapy in Chronic Inflammatory Breast Diseases.

Mastitis is inflammation of breast tissue that may or may not originate from an infection. Two different forms of mastitis have been described, lactational and non-lactational. Lactational mastitis is the most common type and generally conservative therapy that includes milk removal and physical therapy provides symptomatic relief, but antibiotic therapy is also needed. Common types of non-lactational mastitis are periductal mastitis and idiopathic granulomatous mastitis. Treatment includes antibiotics, drainage, and surgery, but usually this is a chronic process and a therapeutic management algorithm for chronic breast inflammation is unclear and has no consensus. Negative-pressure wound therapy is commonly used for various types of wounds but is limited for breast wounds. In this report, we present and discuss two patients with chronic breast inflammation who underwent surgery and were successfully treated using negative-pressure wound therapy to minimize wide tissue defects and cosmetic problems after surgery. Use of negative-pressure wound therapy for breast wounds might be benefical as it is with other wounds but there is scarce information in the literature.

Treatment of hypertriglyceridemia-induced acute pancreatitis with insulin.

INTRODUCTION: Hypertriglyceridaemia (HT)-induced pancreatitis rarely occurs unless triglyceride levels exceed 1000 mg/dl. Hypertriglyceridaemia over 1,000 mg/dl can provoke acute pancreatitis (AP) and its persistence can worsen the clinical outcome. In contrast, a rapid decrease in triglyceride level is beneficial. Insulin-stimulated lipoprotein lipase is known to decrease serum triglyceride levels. However, their efficacy in HT-induced AP is not well documented. AIM: To present 12 cases of AP successfully treated by insulin administration. MATERIAL AND METHODS: Three hundred and forty-three cases of AP were diagnosed at our clinic between 2005 and 2012. Twelve (3.5%) of these cases were HT-induced AP. Twelve patients who suffered HT-induced AP are reported. Initial blood triglyceride levels were above 1000 mg/dl. Besides the usual treatment of AP, insulin was administered intravenously in continuous infusion. The patients' medical records were retrospectively evaluated in this study. RESULTS: Serum triglyceride levels decreased to < 500 mg/dl within 2-3 days. No complications of treatment were seen and good clinical outcome was observed. CONCLUSIONS: Our results are compatible with the literature. Insulin may be used safely and effectively in HT-induced AP therapy. Administration of insulin is efficient when used to reduce triglyceride levels in patients with HT-induced AP.

Determination of optimal operation time for the management of acute cholecystitis: a clinical trial.

INTRODUCTION: Although all studies have reported that laparoscopic cholecystectomy (LC) is a safe and effective treatment for acute cholecystitis, the optimal timing for the procedure is still the subject of some debate. AIM: This retrospective analysis of a prospective database was aimed at comparing early with delayed LC for acute cholecystitis. MATERIAL AND METHODS: The LC was performed in 165 patients, of whom 83 were operated within 72 h of admission (group 1) and 82 patients after 72 h (group 2) with acute cholecystitis between January 2012 and August 2013. All data were collected prospectively and both groups compared in terms of age, sex, fever, white blood count count, ultrasound findings, operation time, conversion to open surgery, complications and mean hospital stay. RESULTS: The study included 165 patients, 53 men and 112 women, who had median age 54 (20-85) years. The overall conversion rate was 27.9%. There was no significant difference in conversion rates (21% vs. 34%) between groups (p = 0.08). The operation time (116 min vs. 102 min, p = 0.02) was significantly increased in group 1. The complication rates (9% vs. 18%, p = 0.03) and total hospital stay (3.8 days vs. 7.9 days, p = 0.001) were significantly reduced in group 1. CONCLUSIONS: Early LC within 72 h of admission reduces complications and hospital stay and is the preferred approach for acute cholecystitis.

Breast Carcinosarcomas.

OBJECTIVE: Carcinosarcomas of the breast are rare and aggressive breast tumors. The optimal treatment strategies and the classification of these difficult to diagnose tumors are not clear in the literature due to their very low incidence. In this study, we aimed to evaluate patients who were operated on for breast carcinosarcoma and discuss the current literature. MATERIALS AND METHODS: Ten patients who were treated with a diagnosis of breast carcinosarcoma between January 2000 - March 2013 at the Izmir Bozyaka Teaching and Training Hospital General Surgery Clinics were retrospectively analyzed. RESULTS: The mean age of the patients was 59.7 (±13.4) years. Eight patients underwent modified radical mastectomy, one patient lumpectomy and one patient breast conserving surgery + sentinel lymph node biopsy procedures. The TNM stage of patients were identified as stage 1 in 2 patients, stage 2 in 6 patients, and stage 3 in 2 patients. 60-month disease-free survival rate was 52.5% (±18.6). The overall survival rate was 53.3% (±20.5). Four patients died during follow-up. CONCLUSION: It is reported that the prognosis of carcinosarcomas are as poor as triple negative epithelial tumors. In contrast to the literature, in our study the disease-free and overall survival rates according to stage were not different from epithelial tumors. In this regard, prospective studies including more patients are required.

Management of rectal foreign bodies.

BACKGROUND: Entrapped anorectal foreign bodies are being encountered more frequently in clinical practice. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault. METHODS: Between 1999 and 2009, 15 patients with foreign bodies in the rectum were diagnosed and treated, at Izmir Training and Research Hospital, in Izmir. Information regarding the foreign body, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients. RESULTS: All patients were males, and their mean age was 48 years (range, 33-68 years). The objects in the rectum of these 15 patients were an impulse body spray can (4 patients), a bottle (4 patients), a dildo (2 patient), an eggplant (1 patient), a brush (1 patient), a tea glass (1 patient), a ball point pen (1 patient) and a wishbone (1 patient, after oral ingestion). Twelve objects were removed transanally by anal dilatation under general anesthesia. Three patients required laparotomy. Routine rectosigmoidoscopic examination was performed after removal. One patient had perforation of the rectosigmoid and 4 had lacerations of the mucosa. None of the patients died. CONCLUSIONS: Foreign bodies in the rectum should be managed in a well-organized manner. The diagnosis is confirmed by plain abdominal radiographs and rectal examination. Manual extraction without anaesthesia is only possible for very low-lying objects. Patients with high- lying foreign bodies generally require general anaesthesia to achieve complete relaxation of the anal sphincters to facilitate extraction. Open surgery should be reserved only for patients with perforation, peritonitis, or impaction of the foreign body.

Superior mesenteric artery syndrome: a rare cause of intestinal obstruction. Diagnosis and surgical management.

Superior mesenteric artery syndrome is a rare but well-known clinical entity characterized by compression of the third or transverse portion of the duodenum against the aorta by the superior mesenteric artery, resulting in chronic, intermittent, or acute, complete or partial, duodenal obstruction. The treatment for this arteriomesenteric compression includes conservative measures and surgical intervention. The aim of the study was to evaluate our surgical management and outcomes of the patients with superior mesenteric artery syndrome. The cases with superior mesenteric artery syndrome admitted between January 2000 and January 2010 were retrospectively investigated from the patients' records. All six patients had a history of chronic abdominal pain, nausea, postprandial early satiety, vomiting, and weight loss. Diagnostic methods included barium esophagogastroduodenography, upper gastrointestinal endoscopy, and computed tomography. Medical management was the first step of treatment in all cases before surgery. Of those, four underwent Roux-en-Y duodenojejunostomy and two underwent gastroenterostomy. Postoperative periods were uneventful and mean duration of hospitalization after the operations was 7 days. Conservative initial treatment is usually followed by surgical intervention for the main problem that is the narrowing of the aortomesenteric angle in patients with superior mesenteric artery syndrome. This syndrome should be considered in the differential diagnosis in patients with chronic upper abdominal pain. Duodenojejunostomy is the most frequently used procedure with a high success rate.
