Inflammation, Tumoral Markers and Interleukin-17, -10, and -6 Profiles in Pancreatic Adenocarcinoma and Chronic Pancreatitis

BACKGROUND

Interleukin profiles can be used as biochemical markers regarding the early diagnosis of pancreatic cancer.

AIMS

To assess CRP, CA 19-9, CEA levels, and interleukin-6, -10, and -17 profiles in pancreatic ductal adenocarcinoma, chronic pancreatitis was compared with a control group, and the correlation with pancreatic cancer survival.

METHODS

A total of 87 patients were prospective divided in pancreatic cancer (n = 53), chronic pancreatitis (n = 22) ,and control group (n = 12). The diagnosis of PDAC was made histologically. The diagnosis of chronic pancreatitis was based on medical history, imaging methods, and endoscopic ultrasound. Systemic concentrations of interleukins were measured using ELISA kits. The patients were followed at 1, 3, and 6 months.

RESULTS

CRP, CA 19-9, and CEA were higher in the pancreatic cancer group (p < 0.001). Interleukin-10 was significantly higher in the pancreatic cancer and chronic pancreatitis groups (p < 0.001). Interleukin-17 was statistically higher in the pancreatic cancer group (p < 0.0001). The cut-off of interleukin-17 of 0.273 had a sensitivity of 90.9 and a specificity of 80.9 with a curve under ROC of 0.80 in order to differentiate between pancreatic cancer and chronic pancreatitis. The serum levels of interleukins are not correlated with the stage of the disease. CRP, CA 19-9, CEA, and interleukin-6, -10, and -17 were lower in patients with survival more than 6 months.

CONCLUSIONS

We detected high levels of interleukin-6, -10, and -17 in chronic pancreatitis and pancreatic cancer. Serum interleukin-17 levels can discriminate between pancreatic cancer and chronic pancreatitis. The prognostic role of interleukins needs to be established.

SRED-ARCE Recommendations for Minimally Invasive Interventions During the COVID-19 Pandemic in Romania

The Romanian Society of Digestive Endoscopy (SRED) and the Romanian Association of Endoscopic Surgery (ARCE) have decided to establish a joint working group to elaborate specific recommendations for organizing the diagnostic and the minimally invasive interventional procedures, in the context of the COVID-19 pandemic. The recommendations are based on the guidelines of the international societies of endoscopy and gastroenterology (ESGE / BSG / ASGE / ACG / AGA), respectively endoscopic surgery (EAES SAGES) (4-8), on the experience of countries severely affected by the pandemic (Italy, France, Spain, USA, Germany, etc.) and they will be applied within the limits of measures imposed at local and governmental level by the competent authorities. On the other hand, these recommendations should have a dynamic evolution, depending on the upward or downward trend of the COVID-19 pandemic at regional and local level, but also according to the findings of professional and academic societies, requiring regular reviews based on the publica tion of further recommendations or international clinical trials. The objectives of the SRED and ARCE recommendations target the endoscopic and laparoscopic surgery activities, to support their non discriminatory used for diagnostic or therapeutic purposes, pursuing the demonstrated benefits of these procedures, in safe conditions for patients and medical staff.

Barrett's Esophagus - State of the Art

Barrett's Esophagus (BE) is defined as a premalignant condition, where the esophageal squamous epithelium is replaced by intestinal epithelium. Specialized intestinal columnar metaplasia, typical for Barrett's esophagus, does not generate any symptoms. Most of the patients are initially seen for symptoms associated with the gastroesophageal reflux disease (GERD), such as heartburn, regurgitation and dysphagia. The histological progression from intestinal metaplasia to dysplasia and then to BE-associated adenocarcinoma forms the argument for screening and endoscopic monitoring. The examination of Barrett's esophagus is controversial. Certain groups suggest a screening of the patients who exhibit more risk factors for the development of esophageal adenocarcinoma (for instance, gastroesophageal reflux disease, age 50, male, high body mass index with abdominal fat distribution). The main reason behind the treatment of acid reflux is that it may lead to chronic esophageal inflammation, which in its turn may predispose to the development of cancer.

Peroral Endoscopic Myotomy Versus Heller Myotomy for Achalasia: Pros and Cons

Achalasia is an esophageal motor disorder that has multiple endoscopic and surgical methods of treatment. However, there is no consensus on optimal therapy in patients suffering from this disorder. This review discusses two therapies with similar but technically different concepts, peroral endoscopic myotomy and Heller surgical myotomy. After a brief introduction to the basic problems of achalasia, technical considerations, intra and postprocedural complications are presented and the advantages and disadvantages of the two procedures are discussed, based on the relevant articles in the literature. Heller surgical myotomy and peroral endoscopic myotomy appear to be similar in performance with similar results in terms of gastroesophageal reflux rates. However, with experience being gained in the field of endoscopic myotomy, this procedure seems more advantageous, with similar success rates to those of the established surgical technique, but offering shorter operating times, shorter hospitalizations and, ultimately, lower costs.

Villous adenoma of the common hepatic duct: the importance of contrast-enhanced ultrasound and endoscopic retrograde cholangiopancreatography for relevant diagnosis. A case report and review of the literature

Adenomas are frequently encountered in the lower digestive tract but are rarely diagnosed in the biliary tree. We report a case of villous adenoma of the common hepatic duct. A 58-year old male was admitted with a four week history of intermittent upper right quadrant pain. Gray scale and contrast-enhanced abdominal ultrasound showed a mass inside the common hepatic duct with arterial enhancement and slow wash-out during the late venous phase. Subsequent endoscopic retrograde cholangiopancreatography and intraductal ultrasound confirmed the presence of the lesion. The final histopathological examination showed villous adenoma of the common hepatic duct with high-grade dysplasia. Contrast enhanced ultrasonography used in conjecture with endoscopic retrograde cholangiopancreatography can help in differentiating biliary tumors.

Contrast-enhanced ultrasound defines vascularization pattern of hamartomatous colonic polyps in Peutz-Jeghers syndrome

The hamartomatous polyps in Peutz-Jeghers syndrome may have malignant potential. To differentiate between hamartomatous and adenomas polyps, vascular characterization can be assessed using noninvasive procedures, such as contrast-enhanced ultrasound (CEUS). The neo-angiogenic characteristics of colorectal adenomas and carcinomas are expressed as an anarchic vascular pattern observed on CEUS. Using CEUS in a patient with Peutz-Jeghers syndrome, we describe for the first time the vascularization of a hamartomatous colonic polyp that exhibits a hierarchy branching pattern.

Factors affecting colonoscopy comfort and compliance: a questionnaire based multicenter study

AIMS

Colonoscopy screening reduces colorectal cancer-related mortality and incidence. However, many patients are reluctant to undergo colonoscopy or return for follow-up because of the investigation's cumbersome and unpleasant nature. We aimed to identify patient-related factors significantly influencing comfort and quality of colonoscopy analyzing responses to a self-administered validated questionnaire.

METHODS

Patients undergoing colonoscopy under sedation in two high-volume endoscopy units were invited to answer a short prevalidated questionnaire regarding preprocedure anxiety, satisfaction with information provided, most worrisome aspect of the procedure and knowledge of the benefits of colonoscopy. Self-reported comfort during colonoscopy as graded on a 10 point visual analog scale was the main variable considered. Univariate analysis identified factors possibly associated with a higher degree of comfort during colonoscopy that were then tested through multivariate logistical regression.

RESULTS

452 questionnaires were returned. Most patients reported an acceptable degree of discomfort during colonoscopy but 70.2% of the respondents considered the information provided prior to the procedure to be insufficient. On multivariate analysis older age, higher degree of satisfaction with information provided (p = 0.04), lower preprocedure anxiety levels (p < 0.01) and endoscopy center (p < 0.01) were shown to correlate with increased comfort during colonoscopy. Education level, previous colonoscopy, gender and bowel prep quality did not influence patient comfort.

CONCLUSIONS

Patient comfort during colonoscopy is dependent on satisfaction with the information provided before the procedure. Higher availability of the physician and better interaction with the patient might decrease patient perceived burden of colonoscopy and lead to higher return rates in the screening and surveillance setting.

Two different types of diabetes mellitus in pancreatic cancer population. Comparative study between new onset and long standing diabetes mellitus on 76 patients with pancreatic cancer

BACKGROUND

There are some studies which have reported a higher diagnosis probability for PC if the DM occurred within the past 2-3 years. Information on the clinical profile of pancreatic cancer (PC) associated with diabetes mellitus (DM) is limited. The aim of the study was to compare clinic-morphological features in patients with new onset DM and PC and long lasting DM and PC, in order to detect new factors or markers which can help in early diagnosis of PC.

METHODS

This study included 76 patients with pancreatic cancer admitted between 2000-2009 in the 4th Medical Clinic Cluj-Napoca; in group A 56 patients with PC and new onset of DM (< 24 months duration) were included and in group B 20 patients with PC and long standing diabetes (> 60 months duration) were included. We compared the demographic, clinical, biochemical and morphological characteristics of new onset or long lasting DM and pancreatic cancer.

RESULTS

New onset DM was more prevalent (74% vs. 26%, p < .05) than long lasting DM among patients with PC. The patients with long lasting DM had a greater frequency of urban environment (100% vs. 55.6% p = .02), a higher body mass index (BMI)(32.1 SD 8.4 vs. 29.9 SD 6.7 kg/m2, p = .05), higher fasting blood glucose levels (182 mg/dL vs. 134 mg/dL, p = .008) and urinary ketone bodies (60% vs. 10.7%, p = .002) compared with those with new-onset DM and PC. There was no statistical difference regarding gender, median age, blood group, location and staging of tumours, long and hard alcohol and cigarettes consumption, between group A and B.

CONCLUSIONS

New onset DM was more significantly frequent than long lasting DM in patients with PC. New onset diabetes DM associated with PC is frequent, mild and non-decompensated. In patients with PC and long lasting DM, the metabolic status and diabetes are imbalanced.

Bleeding Dieulafoy’s-like lesions of the gut identified by capsule endoscopy

Dieulafoy’s-like lesions (DLs-like) represent a cause of obscure gastrointestinal bleeding, enteroscopy being the main diagnostic and therapeutic procedure. Frequently, more than one enteroscopy is needed to identify the bleeding vessel. In our practice, video capsule endoscopy (VCE) identified and guided therapy in four cases of DLs-like; three of them were localized on the small bowel. We report, for the first time, a diagnosis of colonic DL-like performed by colon capsule endoscopy. Two patients presented with severe cardiovascular disorders, being hemodynamically unstable during VCE examination. Based on the VCE findings, only one invasive therapeutic procedure per patient was necessary to achieve hemostasis. VCE and enteroscopy may be regarded as complementary procedures in patients with gut DLs-like.

Stem-like cells in colorectal oncology

Although the treatment for colorectal cancer has seen considerable progress during the past few years, the mortality associated with this type of tumor remains high. This article presents the existing methods of treatment, focusing on the new treatments made possible by the advances in the field of normal and tumor stem cells. Starting from the normal architecture of the colon and the properties of the cells identified in it, we sought to present a few notions concerning these cells which have a direct relevance for both pathology and treatment. The manner in which they divide (symmetrically or asymmetrically) as well as the molecules which control their circulation through the body are just a few examples which are likely to influence the treatment of colorectal cancer in the future.

[Laparoscopic treatment of a large trichobezoar in the stomach with gastric perforation and abdominal wall abscess]

Trichobezoar represents a mass of swallowed hair inside the stomach. Here we report a 17-year-old girl who presented in our department with symptoms of gastric ulcer. Ultrasound examination followed by upper endoscopy revealed a large trichobezoar in the stomach with simultaneous gastric perforation. Laparoscopy also revealed a penetration into the anterior abdominal wall accompanied by abscess at this level. We performed a laparoscopic gastrotomy with trichobezoar extraction and laparoscopic treatment of perforation and abdominal wall abscess. The postoperative evolution was normal and the patient was discharged on the fifth postoperative day. We show that laparoscopic approach may be safely used in the treatment of the large gastric complicated trichobezoar. Several laparoscopic approaches were described for the treatment of tricobezoar and its complications but as far as we know this is the first report of laparoscopic treatment of large tricobezoar and associate gastric perforation.

ERCP in Romania in 2006; a National Programme seems mandatory

BACKGROUND

Endoscopic retrograde cholangio-pancreato-graphy (ERCP) is a procedure used in the diagnosis and treatment of biliary and pancreatic diseases, more preferable to open surgery in terms of a lower risk of morbidity and mortality and costing much less.

METHODS

This was a retrospective, multicenter study, in which we tried to involve the largest medical centers in Romania. They were asked to complete a questionnaire detailing the number of ERCPs performed in 2006, the type of and accessibility to radiology equipment, indications for ERCP, the availability of skilled endoscopists for ERCP and if there were any training pro-grammes.

RESULTS

The number of ERCP procedures performed in 2006 by the participating centers was 2647. There was a strong correlation between the availability of radiology equipment, the number of days allocated by the radiology department for the procedure, and the number of ERCPs performed. Gallstone removal accounted for most (50%) of the therapeutic ERCP indications.

CONCLUSIONS

For a large country such as Romania, a total number of 2647 ERCPs for 2006 is too low. Various important factors such as lack of access to equipment and few skilled ERCP endosco-pists were identified as possible causes. The number of ERCPs performed in Romania should be reorganized to perform 20000 per year in 5 years from now (2012) and give our population access to proper intervention endoscopy. The National Gastroenterology Society should actively encou-rage training in interventional endoscopy, and collaborate with Ministry of Health to have a National Task-force for Endoscop.

Cleaning and disinfection in gastrointestinal endoscopy: current status in Romania

BACKGROUND

Today, endoscopic procedures have become an important tool in the diagnosis and treatment of gastrointestinal diseases. In order to prevent cross infections, the cleaning and disinfection/sterilisation procedures of the endoscopes and accessories are primordial. The GOAL of this paper was to assess the way and the conditions in which endoscopic disinfection is achieved in our country.

METHODS

A study-type questionnaire with eighteen questions, about reprocessing of flexible endoscopes and accessories, was addressed to 37 centres from Romania known to perform digestive endoscopy.

RESULTS

Twenty-nine centres (78.37%) answered the questionnaire. In all the cases, the reprocessing is based on pre-established protocols and the endoscopy nurse has the principal responsibility (62.06%). Enzymatic type detergents are available in 75.86% and glutaraldehyde is the most used disinfector (55.17%). The costs (41.38%) and the financial resources (27.6%) are considered when selecting a product. Despite their advantages, automatic-disinfectors are available in only 34.48% of the cases. All the participants in the study (100%) reused endoscopic instruments, but only 31.03% used them after sterilization by steam autoclaving or ethylene oxide. Adequate facilities for manipulating potential toxic solutions are assured in 48.27%, but separate purpose-designed rooms are available in only 27.58%. Most centres (86.20%) regularly control the quality of the cleaning and disinfection by sampling.

CONCLUSIONS

In general, the disinfection and sterilization of the endoscopes and accessories are carried out in good conditions. With regard to European Union integration, adequate facilities and funds are required to improve the reprocessing activity.

Gastrointestinal lymphomatous polyposis--clinical, endoscopical and evolution features. A case report

Primary gastrointestinal non-Hodgkin lymphoma accounts for 13-18% of all malignant tumours of small bowel and only 1 % of large bowel tumours (1). Multiple lymphomatous polyposis is a rare entity, characterized by the presence of multiple lymphomatous polyps along the gut (2). Majority of cases with gastrointestinal primary lymphoma are classified histologically as "mantle cell" lymphomas. A 59 year old patient was admitted to our clinic for fatigue and rectal bleeding. Endoscopic examination of the colon revealed an infiltrative-exulcerative lesion of the terminal ileon, a polypoid mass on ileocecal valve and multiple polyps over the entire colon and rectum. Gastroscopy revealed polyps into the duodenal bulb. Histopathological and immunohistochemical studies on biopsy specimens from colon and duodenum confirmed gastrointestinal non-Hodgkin lymphoma, probably "mantle cell" lymphoma. Because she was in an advanced stage she received only cytostatic treatment. A clinical, endoscopical and histopathological follow up at 3, 6 and 12 months was performed.

Ruptured hydatid cyst of the liver with biliary obstruction: presentation of a case and review of the literature

The case of a 66 year old woman admitted with a picture of jaundice acute cholangitis is reported. Ultrasonography showed a dilatation of intrahepatic bile ducts, gallbladder hydrops with several stones, enlarged common bile duct (CBD) with hyperechoic material inside and a cystic tumor with hydatid features. With a strong suspicion of a hydatid cyst ruptured in the biliary tree with biliary obstruction, endoscopic cholangiopancreatography was performed. The diagnosis was confirmed by endoscopic retrograde cholangiopancreatography and the hydatid membranes were extracted from the CBD with subsequent clinical improvement. The second step of treatment comprised the surgical cure of the cyst and cholecystectomy. The data from the literature are finally presented with a special emphasis on the ultrasound diagnosis and the endoscopic treatment.

Pain in chronic pancreatitis: assessment and relief through treatment

AIM

To assess two scores of pain used in chronic pancreatitis, to analyse the morphological factors identified by imaging techniques and the extrinsic factors involved in causing pain and in pain evolution during treatment.

PATIENTS AND METHODS

Pain was assessed by means of a unidimensional numeric scale and a multidimensional Mc Gill score in 50 patients with chronic pancreatitis. We prospectively followed up 28 patients over a period of 17 months.

RESULTS

Pain assessment by means of the two scores was statistically comparable. The multidimensional score correlated with the presence of Wirsung stenoses in the univariate analysis and with Wirsung stenoses and their diameter in the multivariate one. The smokers had a smaller rate of pain relief during the treatment. In cases with more morphological changes of severe chronic pancreatitis, pain relief was lower than in cases with fewer changes.

CONCLUSIONS

The McGill score is more appropriate for the quantitative assessment of pain. Smoking reduces the chances of pain relief under treatment. Duct stenoses and Wirsung diameter have the best correlation with pain intensity. The severe chronic pancreatitis changes are negative predictive factors for pain relief under treatment

[Minimally invasive treatment of common bile duct calculi]

Miniinvasive treatment of lithiasis of the common bile duct hasn't reached yet a standard end point. There are multiple techniques used for it. In this study we evaluate its indications, possibilities and limits.

MATERIAL AND METHOD

In a series of 14,024 biliary patients operated over 9 years 719 patients underwent open choledocolithotomy. In 173 (1.2%) of patients we used miniinvasive procedures as follows: 71 cases underwent sequential treatment, 91 laparoscopic treatment and in 11 cases the remnant calculi were extracted 1-6 days postoperative.

RESULTS

Sequential treatment was the preferred treatment when the lithiasis of the common bile duct was detected preoperative. Transcistic extraction was more often performed for the lithiasis diagnosed intraoperative. The conversion to open surgery was performed in 13 cases, remnant calculi were early diagnosed in 11 patients and late diagnosed in 14 cases (the calculi were extracted by endoscopic sphyncterotomy). All patients were healed.

DISCUSSIONS

The miniinvasive procedures have to be practiced as frequently as possible because of rapid healing and early recovery of the patients, despite some disadvantage of them. The choledocotomy and choledocoduodenostomy are exceptional techniques to be used in specific cases.

Portal biliopathy--a lesser known complication of portal hypertension. Case report and review of the literature

Portal biliopathy is a newly introduced term, describing the changes observed in the biliary ducts of portal hypertension patients. We present here the case of a patient diagnosed with portal vein thrombosis secondary to a chronic pancreatitis; the abnormalities in the bile ducts were observed during the endoscopic retrograde cholangiopancreatography. We also review the existing information on this subject in the literature.

Multilocular colorectal tuberculosis and hypogammaglobulinemia

We present the case of a young male patient admitted for weight loss, diarrhea and rectal bleeding. The patient belonged to a low social class and had associated hypogammaglobulinemia. The endoscopy revealed different localized ulcerations of he rectum and a stenosis. By barium enema and hydrosonography multiple stenotic lesions were observed. The pathological examinations detected lesions suggestive for intestinal tuberculosis. A specific therapy led to the improvement of his general state and to the disappearance of diarrhea and rectal bleeding.

Endoscopic mucosal resection for early esophageal cancer. A case report

With the rapid progress of the diagnostic techniques, especially endoscopy, the discovery rate of early superficial cancer of the esophagus has increased markedly. Relatively recently introduced, endoscopic mucosal resection (EMR) is now widely used in the treatment of early stage cancer of the esophagus. We used EMR in the case of a patient who was incidentally diagnosed with a type IIa early esophageal cancer using a band-ligating device. We had no serious complications. At the histopathological examination we noticed that the carcinoma involved the upper third of the submucosal layer. For this reason the patient was given additional therapy (radiotherapy), too. A month after the EMR, at the histological examination we found no local signs of recurrent disease.

Laparoscopic total colectomy for asymptomatic familial adenomatous polyposis

A 20-year-old female patient with familial adenomatous polyposis diagnosed on the occasion of the screening of her family, which had a history of three deaths due malignant colic polyposis, was submitted to total colectomy by laparoscopic technique. Though the histopathological examination performed on two polypi excised by endoscopic technique did not evidence signs of malignant shift, total colectomy was performed, observing the oncological principles. The intervention was uneventful and postoperative course uncomplicated, the patient being socially reintegrated after three weeks. Follow-up examinations performed up to 18 months after the operation showed a favourable evolution and no development in the size and number of polypi.
