RESUMO

Inflammatory cloacogenic polyp is a rare lesion arising in the anal transitional zone. It is usually benign, but rare cases of malignant transformation are known. It is most commonly seen in the adult population from the fourth to the sixth decade of life, but it can be found among children and adolescents as well. The most common clinical symptoms include rectal bleeding and altered bowel habits, although some patients may be asymptomatic. Treatment involves transanal endoscopic microsurgery followed by a bowel regimen with stool softeners. We present the case report of a 14-year-old boy presenting with intermittent rectal bleeding in whom a polypoid lesion was found during digital rectal examination. The patient underwent proctosigmoidoscopy during which the suspicious lesion was removed by transanal endoscopic microsurgery and the histological diagnosis of inflammatory cloacogenic polyp was established. In the postoperative period, the patient was without any further problems. In this case report, we want to raise awareness of this rare diagnosis and emphasize its place in the differential diagnosis of rectal bleeding across all age groups.

RESUMO

Chronic pancreatitis (CP) is a serious condition with a great impact on the quality of life, and it can lead to some serious long-term consequences such as pancreatic cancer or secondary diabetes mellitus. Associated pancreatic exocrine insufficiency leads to malnutrition with weight loss; however, the main symptom of the disease is abdominal pain, often very severe. The primary treatment option for painful CP is pharmacotherapy (pancreatic enzyme replacement therapy, analgesics). If this is not effective, CP can be treated via endoscopy, extracorporeal shockwave lithotripsy (ESWL), their combination, or surgery. We present a case of painful chronic obstructive pancreatitis in a patient successfully treated with ESWL in combination with endoscopy.

RESUMO

BACKGROUND: Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal neoplasm with intermediate malignant potential. Although most often seen in the lungs, it can occur at multiple anatomical locations, including the gastrointestinal tract. An esophageal lesion is extremely rare, however. IMTs present most commonly in children and young adults. The main therapeutic approach is surgical resection. CASE REPORT: We report on the follow-up of a case in a 13-year-old boy with IMT in the esophagus. He underwent surgical resection in 2013 and is free of disease to date. CONCLUSION: Surgical resection is the most preferred therapy. If the resection is complete, the risk of recurrence is low. Nevertheless, every patient should be carefully followed up after the resection.

RESUMO

BACKGROUND: In patients with active Crohn's disease (CD), treatment of intra-abdominal abscess usually comprises antibiotics and radiologically guided percutaneous drainage (PD) preceding surgery. The aim of this study was to investigate the risk of postoperative complications and identify the optimal time interval for surgical intervention after PD. METHODS: A multicentre, international, retrospective cohort study was carried out. Details of patients with diagnosis of CD who underwent ultrasonography- or CT-guided PD were retrieved from hospital records using international classification of disease (ICD-10) diagnosis code for CD combined with procedure code for PD. Clinical variables were retrieved and the following outcomes were measured: 30-day postoperative overall complications, intra-abdominal septic complications, unplanned intraoperative adverse events, surgical-site infections, sepsis and pathological postoperative ileus, in addition to abscess recurrence. Patients were categorized into three groups according to the length of the interval from PD to surgery (1-14 days, 15-30 days and more than 30 days) for comparison of outcomes. RESULTS: The cohort comprised 335 CD patients with PD followed by surgery. Median age was 33 (i.q.r. 24-44) years, 152 (45.4 per cent) were females, and median disease duration was 9 (i.q.r. 3.6-15) years. Overall, the 30-day postoperative complications rate was 32.2 per cent and the mortality rate was 1.5 per cent. After adjustment for co-variables, older age (odds ratio 1.03 (95 per cent c.i. 1.01 to 1.06), P < 0.012), residual abscess after PD (odds ratio 0.374 (95 per cent c.i. 0.19 to 0.74), P < 0.014), smoking (odds ratio 1.89 (95 per cent c.i. 1.01 to 3.53), P = 0.049) and low serum albumin concentration (odds ratio 0.921 (95 per cent c.i. 0.89 to 0.96), P < 0.001) were associated with higher rates of postoperative complications. A short waiting interval, less than 2 weeks after PD, was associated with a high incidence of abscess recurrence (odds ratio 0.59 (95 per cent c.i. 0.36 to 0.96), P = 0.042). CONCLUSION: Smoking, low serum albumin concentration and older age were significantly associated with postoperative complications. An interval of at least 2 weeks after successful PD correlated with reduced risk of abscess recurrence.

RESUMO

Paragangliomas represent a group of neuroendocrine tumours which occur in various localizations. Most of them produce catecholamines, and in advanced cases present with typical symptoms and signs such as palpitations, headache and hypertension. The only curative treatment is radical resection. About one-quarter of paragangliomas are malignant, defined by the presence of distant metastases. There are multiple treatment options for unresectable metastatic tumours. They include radionuclid therapy, chemotherapy, and radiotherapy, although none of them are curative. Cytoreductive surgery can also be considered, especially when the goal is to decrease symptoms related to advanced disease. We present a rare case of a large paraganglioma of the left retroperitoneum. Despite radical surgery, early recurrence of the disease was observed.

RESUMO

Pancreatic carcinoma is an aggressive tumor with a grim prognosis. Accurate staging is essential for indicating surgery in patients with borderline resectable tumors. This paper examines the correlation between pre-operation characteristics of tumors found on CT, infiltration of individual resection margins as confirmed by a pathologist, and the survival of patients with resectable pancreatic head ductal adenocarcinoma. This prospective cohort study involved patients operated on for pancreatic head adenocarcinoma, which was clearly resectable based on the staging CT and intraoperative observation between 2011-2014. Only patients without postoperative complications who underwent adjuvant chemotherapy were analyzed. Seventy-nine patients were assessed, of which 16 (20.3%) had R0 resection and 63 (79.7%) had R1 resection. Patients with R1 results had up to 2.7 times higher risk of death than patients with R0 resection. We found a trend towards shorter survival associated with a closer relationship of the tumor to the superior mesenteric vein/portal vein (SMV/PV) wall in the pre-operation CT examination. Patients with a tumor interface between the vein wall of up to 180 ° circumference had up to 1.97 times higher risk of death than patients without (p=0.131). The results of our work confirmed that in our center, even surgically treated, clearly resectable pancreatic head tumors still have a high occurrence of positive surgical margins (R1 resection) and that tumors with R1 resection had statistically significantly reduced survival compared to R0 resection. A trend for shorter overall survival was found after tumor resection depending on the increasing interface between the tumor and the SMV/PV wall, but this result was not statistically significant.

RESUMO

INTRODUCTION: In surgical practice, hiatal hernias are often related to gastro esophageal reflux disease treatment in which continuous proton pump inhibitor administration is very successful. In large hiatal hernias, life threatening complications may occur. However, planned surgical repair of hiatal hernias is associated with very good functional outcomes with a low risk of postoperative complications. The incidence of large hiatal hernias grows with increasing age of the patient. In geriatric patients, internal comorbidities are also more frequent, including serious conditions. In these patients, one may hesitate whether to perform surgery with regard to the possible risk of postoperative complications. Conservative treatment of hiatal hernias is associated with a higher risk of stomach volvulus or severe bleeding as the most frequent complications. METHODS: We performed a retrospective study of patients operated on for a large hiatal hernia at the Department of Surgery, University Hospital Brno, between 2010 and 2016 (86 months). The patients were divided into 2 groups depending on the type of operation: acute (A) and elective (B). We evaluated demographic data, the nature of preoperative symptoms, type of surgery and postoperative complications. RESULTS: 120 patients were operated on for large hiatal hernia in this period of time. Group A involved 22 operated patients, group B 98 patients. There was a significantly higher number of laparotomies in the acute patient group compared to the elective group B (72.7 % vs. 23.5%, p.

RESUMO

BACKGROUND: Gastrointestinal stromal tumours (GIST) are rare malignant mesenchymal tumours with an incidence of 1 in 100,000. They represent only 5% of gastrointestinal tumours. The GISTs are mainly located in the stomach (60-70%) and in the rectum in < 5% of cases. In the case of localized, resectable tumours, the treatment is surgical resection. Depending on the size and localization of the tumour in the rectum, either a local excision, rectal resection with anastomosis, or abdominoperitoneal amputation with permanent stoma can be performed. In contrast to carcinomas, the metastasis of GISTs into lymph nodes is rare; therefore, from an oncological point of view, lymphadenectomy in the form of mesorectal excision is not required. Neoadjuvant treatment using tyrosine-kinase inhibitors (TKI) is recommended for tumours larger than 5 cm and in case of tumours infiltrating surrounding organs or sphincters in order to achieve complete resectability, less mutilating and continent procedure. In GISTs with a positive resection line, re-resection can be attempted. Adjuvant TKI therapy can be considered in cases of CD117 positivity and after resections of GISTs with medium and high-risk malignant behaviour. The TKI treatment is also indicated in cases of unresectable and metastatic GISTs. METHODS: Data obtained from the GIST registry by the 1st January 2017, when 10 centres in the Czech Republic were contributing to the registry, were analysed. RESULTS: We analysed 1,095 patients out of which 45 (4.1%) had GIST localized in the rectum. The average age of the patients was 60 years. There were significantly more males (68.9%; p = 0.0007) and symptomatic patients (62.2%; p = 0.034). In total, 82% of the patients underwent surgery. Local excision was performed in 37.8%, resection of the rectum with anastomosis in 29.7%, and Miles operation in 29.7%. In the cohort, most tumours were 2-5 cm in size and almost half of the tumours presented a high risk of malignant behaviour. Systemic treatment was reported in 73% of patients. A complete remission was achieved in 80% of patients with GIST of the rectum. The median survival rate was 11.3 years and the 5-year survival rate is 90.6%. CONCLUSION: Despite the success of TKI treatment, the only potentially curative method of rectal GISTs is a surgical R0 resection. Given the relatively rare frequency of these tumours, proper diagnosis and treatment is demanding. Therefore, these patients should be preferably treated in specialised centres.

RESUMO

BACKGROUND: Immunoglobulin (Ig) G4 associated sclerosing cholangitis is a rare inflammatory disease of the biliary tract. Although it is a very progressive condition, it responds to steroid therapy. IgG4 associated sclerosing cholangitis can mimic pancreatic carcinoma, cholangiocarcinoma, and primary sclerosing cholangitis; therefore, it is very important to obtain a differential diagnosis. IgG4 sclerosing cholangitis is a biliary form of IgG4 related systemic disease, in which afflictions of more organs is afflictions of more organs are common, typically biliary form together with pancreatic one. Nonspecific symptoms are obstructive icterus, fatigue, and weight loss. Atypical imaging of the biliary tree and pancreas can be used to distinguish it from other diseases. Laboratory data show elevation of bilirubin, liver enzymes, IgG4 and total IgG concentrations. Sometimes IgE is also elevated with the eosinophilia, oncomarker CA 19-9 and autoimmune antibody is sometimes detected. CASE: This article presents a case of IgG4 sclerosing cholangitis and its related findings. The patient was intially referred for suspected pancreatic tumour, the presumed diagnosis was later changed to cholangiocarcinoma type 4 with concurrent autoimmune pancreatitis. Atypical imaging in cholangiography made us suspect IgG4 inflammation and the diagnostic process began. CONCLUSION: The diagnosis of this disease uses so called HISORt criteria. It is a very complex process in which the success of steroid therapy as a final step can be conclusive, as it was in our case. It is essential to exclude a malign neoplastic growth. The authors declare they have no potential confl icts of interest concerning drugs, products, or services used in the study.

RESUMO

Despite several studies, the role and timing of endoscopic retrograde cholangiopancreatography (ERCP) in the case of acute biliary pancreatitis (ABP) remains a subject of discussion.There is a clear indication of early ERCP within 72 hours in patients with ABP andcholedochal obstruction, moreover the ERCP within 24 hours in cases of cholangitis. However, the role of ERCP in patients with ABP without symptoms of cholangitis or concrements obstructing the bile duct is controversial. If ABP is indicated for the ERCP, the earlier the ERCP is performed the less complications it is associated with. The decision to perform ERCP is often based on findings from a biochemical and transabdominal ultrasound examination. The results of these examinations may, but may not, confirm the presence of stones in the choledochus. An effective and safe method approaching the sensitivity of ERCP in the diagnosis of concrements in the choledochus is endoscopic ultrasonography (EUS) and magnetic resonance cho-langiopancreatography (MRCP). The cholecystectomy should be performed to prevent a recurrence of pancreatitis and biliary problems after the successfully treatment of ABP. Key words: acute biliary pancreatitis choledocholithiasis cholangitis endoscopic retrograde cholangiopancreatography.

RESUMO

Spontaneous retroperitoneal hematoma is a serious complication of anticoagulation and antiplatelet therapy. Its incidence has increased in recent years due to an increasing number of patients on this treatment. A number of case series have been described in the literature. In the vast majority of cases, the hemodynamically stable patients were treated either conservatively or by selective radiological embolization of the bleeding source. A surgical approach is reported as a last choice in the cases where the conservative therapy fails, radiological intervention is unavailable, in patients with continuous bleeding or in patients who develop abdominal compartment syndrome. In our case report, we present a patient on anticoagulation therapy for deep venous thrombosis complicated by massive retroperitoneal bleeding: surgery was used as the method of first choice and the treatment was successful. Key words: retroperitoneal hematoma bleeding anticoagulation treatment surgery.

RESUMO

INTRODUCTION: Crohns disease (CD) as a chronic inflammatory disease can affect the entire digestive tract and therefore involves a wide range of symptoms and health problems. It often mimics other diseases of the digestive tract. In the case of acute abdomen in a patient with CD, it is necessary to approach it individually in cooperation with a gastroenterologist in order to reduce the extent of resection and to ensure fewer resections. CASE REPORTS: In our two case reports, we present patients with bowel obstruction and inflammatory acute abdomen. The first patient benefits from conservative treatment despite the presence of a bowel obstruction (resulting from inflammation) before subsequent surgical treatment. It is a relatively common acute complication of CD. The second patient, despite her ongoing pregnancy and the impossibility of using appropriate imaging techniques in the follow-up treatment, with regard to her clinical condition, requires an urgent surgical solution due to a fairly rare perforation to abdominal cavity. Key words: Crohns disease - surgery - acute abdomen - bowel obstruction - peritonitis.

RESUMO

PURPOSE: Crohn's disease (CD) belongs to chronic disorders with unpredictable disease course. The aim of this study was to identify how genetic testing (NOD2/CARD15) can be used in patients with CD to predict the need for surgical treatment (to define an aggressive type of disease where the patient can profit from early surgery). METHODS: The patients who were tested genetically had undergone a surgery due to CD at the Department of Surgery University Hospital Brno Bohunice between 2010 and 2016. The control group consisted of patients with CD who had been diagnosed with CD at least 5 years prior to the testing and had not required any surgical intervention. The second control group was healthy subjects. RESULTS: In total, there were 117 operated patients for CD, 77 patients with CD that had not undergone surgery for CD and 30 healthy subjects. For patients with at least one genetic mutation, the risk of the necessity of surgical treatment of CD is 1.96 times higher than for patients with no mutation. Patients with two or more mutations were generally operated on at a younger age, in a shorter time after being diagnosed and each patient had a partial resection of the ileum. CONCLUSION: The group of operated patients with CD had a significantly higher distribution of at least one genetic mutation as opposed to the non-operated group. In patients with two or more mutations, the disease course was more aggressive. This group of patients might profit from the conservative top-down or early surgical therapy.

RESUMO

Background Stomach preparation by ischaemic conditioning prior to oesophageal resection represents a potential method of reducing the risk of anastomotic complications. This study compares the results of the anastomotic complications of cervical anastomosis after oesophagectomy with a short interval after ischaemic conditioning (group S) and a long interval (group L). Methods Subjects undergoing oesophagectomy for carcinoma after ischaemic conditioning were divided into two groups. Group S had a median interval between ischaemic conditioning and resection of 20 days, while for group L the median interval was 49 days. Anastomotic leak and anastomotic stenosis in relation to the interval between ischaemic conditioning and actual resection were followed. Results After ischaemic conditioning, 33 subjects in total underwent surgery for carcinoma; 19 subjects in group S and 14 subjects in group L. Anastomotic leak incidence was comparable in both groups. Anastomotic stenosis occurred in 21% of cases in group S and 7% of cases in group L (not statistically significant). Conclusions A long interval between ischaemic conditioning and oesophagectomy does not adversely affect the postoperative complications. A lower incidence of anastomosis stenoses was found in subjects with a longer interval, however, given the size of our sample, the statistical significance was not demonstrated. Both groups seem comparable in surgical procedure course and postoperative complications.

RESUMO

In confocal laser endomicroscopy (CLE), a type of optical microscope that uses a laser beam as its light source and processes the acquired image by processor unit is used. Although the principle behind the device has been known since 1957, its use in clinical practice has only recently been enabled by technical developments, and it is therefore a relatively new modality in differential diagnosis. CLE enables real-time microscopic imaging of the tissue under investigation and in fact non-invasive in vivo biopsy. First experiences with CLE have primarily been obtained in the field of endoscopy, in particular in the pathology of the esophagus, stomach, bile duct, pancreas, and colon. Further to its use in endoscopy, CLE was recently developed for perioperative use, with the most experience gained in neurological, breast, and prostate surgery. Numerous prospective randomized trials have confirmed the benefits of CLE in tumor screening, differential diagnosis of tumors or inflammatory diseases, earlier diagnostics of diseases, and reducing the number of required endoscopic examinations. In addition, CLE is associated with minimal side effects. A known possible side effect is allergy to the fluorescein used to stain tissues during the examination. Extending of endoscopic examination or surgery is minimal in the hands of trained personnel. Current limiting factors of CLE include insufficient clinical experience, the price of the CLE device and probes, and the subjectivity inherent in the evaluation of microscopic images by the endoscopist or surgeon. This article summarizes published studies of CLE in the diagnostics of oncological diseases of the gastrointestinal tract.Key words: confocal microscopy - gastrointestinal tract - neoplasms The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.Submitted: 9. 2. 2017Accepted: 26. 2. 2017.

RESUMO

Acute appendicitis with its characteristic clinical course is one of the most common diagnoses that require urgent surgery. The following three case reports present patients with symptoms typical of acute appendicitis which was, however, not confirmed intraoperatively. Preoperative CT or MRI were not requested because symptoms clearly indicated acute appendicitis. The first case describes a male patient with right-sided diverticulitis, the second case report involves a pregnant woman in 33rd week of gestation with right adnexal torsion due to a dermoid cyst, and in the last report, a case of spontaneous perforation of appendiceal mucinous neoplasm is presented.Key words: right-sided diverticulitis - dermoid cyst - adnexal torsion - mucinous neoplasm - pseudomyxoma peritonei - appendicitis.

RESUMO

INTRODUCTION: Crohn´s disease (CD) highly affects a patient´s quality of life. The aim of the study was to find out the impact of surgery on the quality of life (QoL) in CD patients and factors affecting their postoperative QoL. METHODS: 90 patients with CD who underwent surgery (bowel resection) filled out an EORTC QLQ-CR29 questionnaire preoperatively and again after the surgical procedure. RESULTS: 77% of the patients experienced a positive change (p<0.001), 22% negative and 11% no change. CONCLUSION: In this cohort, we proved that surgical treatment improves the overall QoL in patients with CD. To determine factors which affect postoperative QoL, more patients need to be enrolled in future studies.Key words: Crohn´s disease - quality of life - surgery - bowel resection - Czech cohort.

RESUMO

The authors describe their experience with surgical treatment of benign rare lymph proliferation - Castlemans disease (CD). It occurs in unicentric and multicentric forms. The very low incidence of the disease makes it very difficult to design larger prospective studies. Cases of two leading localizations of the unicentric form of CD - intrathoracic and retroperitoneal with special emphasis on the preoperative diagnosis and imaging options are described. This article underlines the curative potential of surgical treatment where a complete resection of the affected lymph node leads to eradication in almost 100% of the cases. The discussion is focused on the forms of CD - different localization, clinical symptoms and course of disease. It discusses the differential diagnosis, particularly difficult in the multicentric form, emphasizing the need to exclude malignant lymphoma. The etiopathogenesis of the disease is presented, mentioning its association with HIV (Human Immunodeficiency Virus) infection and HHV-8 (Human herpers virus 8) infection and the importance of overproduction of proinflammatory cytokines. The importance of surgical therapy for the unicentric form of CD is highlighted as compared to the multicentric form, where the surgeon´s task involves taking a biopsy - required for an accurate diagnosis.Key words: Castlemans disease - lymphoproliferation - lymphadenopathy - surgical treatment.
