Recent Trends in Non-Invasive Methods of Diagnosis and Evaluation of Inflammatory Bowel Disease: A Short Review.

Inflammatory bowel diseases are a conglomerate of disorders causing inflammation of the gastrointestinal tract, which have gained a significant increase in prevalence in the 21st century. As they present a challenge in the terms of diagnosis as well as treatment, IBDs can present an overwhelming impact on the individual and can take a toll on healthcare costs. Thus, a quick and precise diagnosis is required in order to prevent the high number of complications that can arise from a late diagnosis as well as a misdiagnosis. Although endoscopy remains the primary method of evaluation for IBD, recent trends have highlighted various non-invasive methods of diagnosis as well as reevaluating previous ones. This review focused on the current non-invasive methods in the diagnosis of IBD, exploring their possible implementation in the near future, with the goal of achieving earlier, feasible, and cheap methods of diagnosis as well as prognosis in IBD.

Surgical management of hydatid cyst disease of the liver: An improvement from our previous experience?

BACKGROUND: Hydatid liver disease remains an important issue in endemic areas, which may require immediate surgery. Although laparoscopic surgery is on the rise, the presence of certain complications may require conversion to the open approach. AIM: To compare the results of laparoscopic treatment and the open approach in the context of a 12-year single institution experience, and to perform a further comparison between results from the current study and those from a previous study. METHODS: Between January 2009 and December 2020, 247 patients underwent surgery for hydatic disease of the liver in our department. Of the 247 patients, 70 underwent laparoscopic treatment. A retrospective analysis between the two groups was performed, as well as a comparison between current and previous laparoscopic experience (1999-2008). RESULTS: There were statistically significant differences between the laparoscopic and open approaches regarding the cyst dimension, location, and presence of cystobiliary fistula. There were no intraoperative complications in the laparoscopic group. The cutoff value for the cyst size regarding the presence of cystobiliary fistula was 6.85 cm (P = 0.001). CONCLUSION: Laparoscopic surgery still plays an important role in the treatment of hydatid disease of the liver, with an increase in its usage over the course of years that has shown benefits regarding the postoperative recovery with a decreased rate of intraoperative complications. Although experienced surgeons can perform laparoscopic surgery in the most difficult conditions, there are some selection criteria that need to be maintained for higher quality results.

Sperm protein antigen 17 and Sperm flagellar 1 cancer testis antigens are expressed in a rare case of ciliated foregut cyst of the common hepatic duct.

INTRODUCTION: Ciliated foregut cysts (CFCs) are frequently described in liver, pancreas and gallbladder and generally considered benign although one case of squamous cell metaplasia and five cases of squamous cell carcinoma arising from a ciliated hepatic foregut cyst have been reported. Here we explore two cancer-testis antigens (CTAs), Sperm protein antigen 17 (SPA17) and Sperm flagellar 1 (SPEF1) expression in a rare case of CFC of the common hepatic duct MATERIALS AND METHODS: 3 µm-thick CFC sections were immunohistochemically treated with antibodies raised against human SPA17 or SPEF1. In silico Protein-Protein Interaction (PPI) network and differential protein expression were also investigated RESULTS: Immunohistochemistry revealed SPA17 and SPEF1 in the cytoplasm of ciliated epithelium. SPA17, but not SPEF1, was also detected in cilia. The PPI networks demonstrated that other CTAs are significantly predicted functional partners with SPA17 and SPEF1. The differential protein expression demonstrated that SPA17 was higher in breast cancer, cholangiocarcinoma, liver hepatocellular carcinoma, uterine corpus endometrial carcinoma, gastric adenocarcinoma, cervical squamous cell carcinoma, bladder urothelial carcinoma. SPEF1 expression was higher in breast cancer, cholangiocarcinoma, uterine corpus endometrial carcinoma and kidney renal papillary cell carcinoma CONCLUSIONS: Our study suggests that further characterization of SPA17 and SPEF1 in patients with CFCs might provide significant insights to understand the mechanisms underlying their potential to malignant transformation.

The Multifaceted Role and Regulation of Nlrp3 Inflammasome in Colitis-Associated Colo-Rectal Cancer: A Systematic Review.

Colitis-associated colo-rectal cancer remains the leading cause of mortality in inflammatory bowel diseases, with inflammation remaining one of the bridging points between the two pathologies. The NLRP3 inflammasome complex plays an important role in innate immunity; however, its misregulation can be responsible for the apparition of various pathologies such as ulcerative colitis. Our review focuses on the potential pathways of upregulation or downregulation of the NLRP3 complex, in addition to evaluating its role in the current clinical setting. Eighteen studies highlighted the potential pathways of NLRP3 complex regulation as well as its role in the metastatic process in colo-rectal cancer, with promising results. Further research is, however, needed in order to validate the results in a clinical setting.

The impact of the COVID-19 pandemic on the mental health of patients diagnosed with inflammatory bowel diseases.

Understanding the profound impact of a viral pandemic on the mental health of patients with autoimmune diseases undergoing biological treatment is crucial for future insights. This cross-sectional case-control study aimed to assess the mental health implications of the COVID-19 pandemic on individuals with inflammatory bowel disease (IBD) in Romania, spanning from November 2022 to March 2023. A specialized self-report questionnaire in the Romanian language was developed to measure the multifaceted effects of COVID-19 on the mental well-being of these patients. The findings revealed a significant decline in the mental health of patients with IBD during the pandemic compared to the control group. Patients with IBD exhibited elevated levels of anxiety and concern regarding the virus. Intriguingly, despite the challenges, the vaccination rate was notably higher among patients with IBD, indicating a proactive approach to safeguarding their health. The study also shed light on various coping mechanisms employed by patients with IBD to navigate the pandemic-related restrictions. Engaging in activities such as social media and computer games emerged as effective strategies for managing heightened stress and limitations. In conclusion, the emergence of a novel viral pathogen represents a significant distress factor for patients with autoimmune diseases. Recognizing and comprehending these consequences enhances our understanding of the intricate interplay between physical and mental health and equips authorities with valuable insights to better manage future epidemics or viral outbreaks. This study underscores the importance of tailored support systems and strategies for patients with autoimmune diseases during global health crises.

The Role of IL-22 in Wound Healing. Potential Implications in Clinical Practice.

Wound healing is a complex process that is mediated and influenced by several cytokines, chemokines, and growth factors. Interleukin-22 (IL-22) is a cytokine that plays a critical role in tissue regeneration. Our study is a systematic review that addressed the implications of IL-22 in the healing of wounds caused by external factors. Thirteen studies were included in our review, most of them being experimental studies. Three clinical studies underlined the potential role of IL-22 in day-to-day clinical practice. IL-22 plays a central role in wound healing, stimulating the proliferation, migration, and differentiation of the cells involved in tissue repair. However, overexpression of IL-22 can cause negative effects, such as keloid scars or peritoneal adhesions. The results of the presented studies are promising, but further research that validates the roles of IL-22 in clinical practice and analyzes its potential implication in surgical healing is welcomed.

Risk Factors for Extraintestinal Manifestations in Inflammatory Bowel Diseases - Data from the Romanian National Registry.

BACKGROUND AND AIMS: Identifying the risk factors for extraintestinal manifestations (EIMs) in inflammatory bowel diseases (IBD) may optimize the therapeutic decision. We aimed to assess the prevalence of EIMs in IBD patients in Romania and to determine the risk factors. METHODS: We analyzed 2,626 patients registered in the Romanian IBD Prospect National Registry. We performed a descriptive cross-sectional study to assess the point prevalence of EIMs, calculating global prevalence and analyzing the different types of EIMs and their respective frequencies were carried out. Demographic and clinical risk factors were researched as possible predictors for EIMs development, based on the results of the univariate and multivariate logistic regression analysis. RESULTS: The overall point prevalence of EIMs was 16.3%. A significantly higher frequency of EIMs in Crohn's disease (CD) was noted in comparison to ulcerative colitis (UC) and IBD unclassified (IBDU) (23.2% vs 11.3% and 16.3%, respectively, p<0.001). The most frequent type of EIM was peripheral arthropathy (8.3%), significantly associated with CD (p<0.001). Univariate analysis highlighted the significant independent common predictive risk factors for EIMs, in both CD and UC patients: female gender, patient's urban area of origin, anemia, hypoalbuminemia, and high level of C-reactive protein (CRP), while significant independent IBD phenotype-related risk factors were ileocolonic location and concomitant involvement of upper gastrointestinal tract for CD, non-smoker status and both moderate and severe disease activity for UC (p<0.05). Multivariate analysis determined that female CD patients with moderate or severe disease activity, with other than isolated ileal disease, and female UC patients with moderate or severe extensive colitis are the most likely to develop EIMs. CONCLUSIONS: IBD patients are experiencing EIMs in a large proportion, with higher rates for CD. As EIMs negatively affect patient outcomes, foreseeing the risk by identifying independent and associated predictive factors could be a first step to optimal work-up and treatment.

Hepatic Hydrothorax-An Independent Decompensating Event Associated with Long-Term Mortality in Patients with Cirrhosis.

Background: Hepatic hydrothorax (HH) is an understudied complication of decompensated cirrhosis. We aimed to evaluate the long-term prognosis of patients with HH by comparing them with a matched non-HH group. Methods: This retrospective study included 763 consecutive patients hospitalized for decompensated cirrhosis and ascites. Ninety-seven patients with HH were matched for survival analysis with non-HH patients based on liver disease severity. Results: The prevalence of HH was 13.1%. Patients with HH had significantly worse overall liver function. Upon matching, patients with HH had a lower long-term survival (15.4% vs. 30.9% at 5 years) with a mean overall survival of 22.2 ± 2.2 months for the HH group vs. 27.1 ± 2.6 months for the non-HH group (Log Rank-0.05). On multivariate survival analysis using Cox regression, the MELD-Na score, ALBI grade, hepato-renal syndrome, and grade III ascites had a significant impact on mortality in patients with HH. In patients with HH, a MELD-Na score ≥ 16, ALBI grade III, hepato-renal syndrome, or severe ascites delineated high-mortality risk groups. Conclusions: HH is consistently associated with more advanced liver disease. Patients with HH have worse long-term survival, their prognosis being closely intertwined with overlapping decompensating events.

Extrahepatic cholangiocarcinoma: Current status of endoscopic approach and additional therapies.

The prognosis of patients with advanced or unresectable extrahepatic cholangiocarcinoma is poor. More than 50% of patients with jaundice are inoperable at the time of first diagnosis. Endoscopic treatment in patients with obstructive jaundice ensures bile duct drainage in preoperative or palliative settings. Relief of symptoms (pain, pruritus, jaundice) and improvement in quality of life are the aims of palliative therapy. Stent implantation by endoscopic retrograde cholangiopancreatography is generally preferred for long-term palliation. There is a vast variety of plastic and metal stents, covered or uncovered. The stent choice depends on the expected length of survival, quality of life, costs and physician expertise. This review will provide the framework for the endoscopic minimally invasive therapy in extrahepatic cholangiocarcinoma. Moreover, additional therapies, such as brachytherapy, photodynamic therapy, radiofrequency ablation, chemotherapy, molecular-targeted therapy and/or immunotherapy by the endoscopic approach, are the nonsurgical methods associated with survival improvement rate and/or local symptom palliation.

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.

Laparoscopic splenectomy for hereditary spherocytosis. A case series and review of the literature.

Hereditary spherocytosis (HS) is a common inherited hemolytic anemia caused by a defective erythrocyte cellular membrane. Irrespective of type of surgery performed, several case reports comparing the two type of procedures, have not proven any significant difference between serum bilirubin, serum hemoglobin, red blood cells' and platelets' count, in the followup period at 6 and 12 months respectively, even if platelet count has maintained high for the first 6 months postoperatively, justifying an oral antiplatelet therapy for this time interval. In the present work, we present the use of LS as the treatment of choice for HS as a case series, with all the characteristics. KEY WORDS: Hereditary Spherocytosis, Laparoscopic Splenectomy.

Diagnostic Delay in Romanian Patients with Inflammatory Bowel Disease: Risk Factors and Impact on the Disease Course and Need for Surgery.

BACKGROUND: The epidemiology of inflammatory bowel disease [IBD] in Eastern Europe is poorly understood, particularly with regard to diagnostic delay. Here we investigated the factors leading to delayed diagnosis and the effect of the delay on several disease progression and outcome measures. METHODS: A total of 1196 IBD cases [682 ulcerative colitis [UC], 478 Crohn's disease [CD], 36 indeterminate colitis] from the Romanian national registry IBDPROSPECT were reviewed. Standard clinical and demographic factors were evaluated as predictors of a long diagnostic delay in both CD and UC. Diagnostic delay was subsequently evaluated as a potential risk factor for bowel stenoses, bowel fistulas, perianal fistulas, perianal surgery, and intestinal surgery in CD patients. RESULTS: The median diagnostic delay was significantly longer in CD [5 months] than in UC [1 month] patients [p < 0.001]. Compared with 5 months for UC patients, 75% of CD patients were diagnosed within 18 months of symptom onset. In CD patients, extra-ileal location was a protective factor (odds ratio [OR], 0.5; p = 0.03), whereas being an active smoker [OR, 2.09; p = 0.01] and symptom onset during summer [OR, 3.35; p < 0.001] were independent risk factors for a long diagnostic delay [> 18 months]. In UC patients, an age > 40 years was a protective factor [OR, 0.68; p = 0.04] for a long delay. Regarding outcomes, a long diagnostic delay in CD patients positively correlated with bowel stenoses [OR, 3.38; p < 0.01] and any IBD-related surgery [OR, 1.95; p = 0.03] and had a positive trend for intestinal fistulas [OR, 2.64; p = 0.08] and perianal fistulas [OR, 2.9; p = 0.07]. Disease duration since diagnosis positively correlated with bowel stenoses [OR, 1.04; p = 0.04], any IBD-related surgery [OR, 1.04; p = 0.02], and intestinal surgery [OR, 1.07; p < 0.01]. CONCLUSIONS: A long diagnostic delay in IBD correlates with an increased frequency of bowel stenoses and need for IBD-related surgery.

Exosome-Carried microRNA-375 Inhibits Cell Progression and Dissemination via Bcl-2 Blocking in Colon Cancer.

BACKGROUND AND AIMS: Worldwide, colorectal cancer (CRC) is the third most common cancer in men and second in women. The aim of the current study was to identify whether the miR-375 is indeed down-regulated in metastatic CRC and if it could be considered as a potential minimally invasive prognostic biomarker for CRC. METHODS: Exosomes were isolated and characterized from patients with liver metastasis from CCR. The characterization of exosome was performed using TEM/SEM. HCT116 cells were treated with miR-375 mimic, NSM and miR-375 inhibitor. Functional assays included cell counting assay for 14 days, Matrigel invasion assay, apoptosis assay by flow cytometry using Annexin V-FITC, RT-PCR and Western blotting. RESULTS: Increased proliferation potential was proven for the cells transfected with miR-375 inhibitor, while the miR-375 mimic decreased the cell number. The cells transfected with the miR-375 inhibitor are aggressive and cross the membrane; 3.84% of the cells transfected with the miR-375 inhibitor entered apoptosis, while 6.45% of those transfected with the non-specific mimic were in programmed cell death, less than those transfected with the microRNA. RT-PCR for Bcl-2 expression showed that Bcl-2 is down-regulated for miR-375 inhibitor and up-regulated for the miR-375 mimic, a result confirmed by Western blotting. CONCLUSION: The present study brings to the forefront new data that suggest miR-375 as a new player in controlling the pathways responsible for inhibiting the natural history of CRC tumor cells, via the Bcl-2 pathway.

Laparoscopic rectal resection versus conventional open approach for rectal cancer - a 4-year experience of a single center.

PURPOSE: This study was carried out to compare the therapeutic outcomes and complications of the laparoscopic and the conventional open surgery technique used for treating rectal cancer. Another goal was to find the fastest and most accurate method of treatment for rectal cancer, along with establishing the advantages and disadvantages of the two surgical techniques, depending on cancer location and its stage. METHODS: A total of 172 patients diagnosed with rectal cancer and hospitalized in the Department of Surgery III between January 1st 2008 and December 31st 2011 were studied. The laparoscopic approach was performed on 29 (16.8%) patients, and the remaining 143 (83.2%) underwent the conventional Miles/Lloyd-Davies abdominoperineal resection. A longitudinal study was conducted on patients with rectal resection, the used data being obtained from the database of the Department of Surgery III, hospital records, protocols and clinical charts of rectal cancer cases. RESULTS: There were no statistically significant differences regarding symptoms, gender, age, body mass index (BMI), tumor site, TNM stage, intraoperative accidents, operative time, and postoperative mortality between the two groups. The laparoscopic group presented advantages regarding antibiotic and analgesic therapy, early mobilization, hospital stay, intraoperative blood loss, resuming oral nutrition, bowel transit resumption, postoperative complications and wound complications. CONCLUSION: Laparoscopic abdominoperineal resection for rectal cancer is feasible, safe and effective. It can be safely performed by an experienced team, reducing the rate of postoperative complications, the need for blood transfusions, the adminstration of antibiotics and painkillers, allowing faster bowel transit resumption, shortening hospital stay and providing superior aesthetic results.

Malignant familial adenomatous polyposis treated by laparoscopic colectomy and ileal pouch anal anastomosis: a case report.

The mean age of colorectal cancer in untreated familial adenomatous polyposis (FAP) is 39 years. We present the case of a 21-year-old patient with FAP and colorectal cancer. The patient was detected with significant family history: her mother died at age 45 with colon cancer; two uncles were diagnosed with colon cancer at the age of 40 and 43 and one aunt at the age of 45 with colon cancer and gastric cancer. The treatment was laparoscopic restorative proctocolectomy with total excision of the mesorectum and ileal pouch anal anastomosis completed with endoanal excision of inferior rectal polyps. The histopathological report described a well differentiated rectal adenocarcinoma T1N1aMx developed on a tubulo-villous adenoma located on the rectosigmoid jonction, the rest of the polyps with benign histology.

Open or laparoscopic treatment for hydatid disease of the liver? A 10-year single-institution experience.

BACKGROUND: Selection of the most appropriate treatment to obtain the lowest morbidity, mortality, and recurrence rates is mandatory for hydatid disease of the liver. This study evaluated the results of laparoscopic treatment (compared with the open approach) in the context of a 10-year single-institution experience. METHODS: Between January 1998 and January 2008, 333 patients with hydatid disease of the liver underwent surgery in the authors' department. Only the following aspects were considered as selection criteria for laparoscopic surgery: liver cyst not located in segment 1 or 7, with corticalization on the surface and no evidence of intrabiliary rupture. Of 62 patients who underwent laparoscopic treatment, 3 required conversion to open surgery. The remaining 59 patients (group 1) were analyzed. During the same period, 271 patients with hepatic hydatid disease underwent conventional surgery, but only 172 records were compatible with the criteria for the laparoscopic approach and the respective patients were retrospectively reviewed (group 2). RESULTS: Conversion to open surgery occurred in three cases (4.84 %). The mean cyst diameter was 6.62 cm (range, 2-15 cm) in group 1 and 7.23 cm (range, 2-18 cm) in group 2 (p = 0.699). The mean operative time was 72 min (range, 45-140 min) in group 1 and 65 min (range, 35-120 min) in group 2 (p < 0.001). The general complication rate and abdominal wound complication rate were respectively 0 % and 0 % in group 1 (p = 0.023) compared with 5.23 and 8.72 % in group 2 (p = 0.015). The mean hospital stay was 6.42 days (range, 1-21 days) in group 1 and 11.7 days (range, 4-80 days) in group 2 (p < 0.001). The mean follow-up period was 24.2 months (range, 6-32 months) in group 1 and 28.4 months (range, 6-40 months) in group 2. No recurrences were observed in either group during this period. CONCLUSION: Laparoscopic surgery provides a safe and efficacious approach for almost all types of hepatic hydatid cysts. Large, prospective, randomized trials are needed to confirm its superiority.

Minimal invasive treatment of abdominal multiorgan echinococcosis.

Hydatid disease is a severe zoonosis, exerting a high economic and social impact through its numerous complications, leading to disabilities, even death. Because of technical developments, especially the increasing experience of surgeons, laparoscopic surgery has been extended so that it can be successfully applied to abdominal hydatid cysts. We present the case of a 16-year-old patient who came to our clinic for upper abdominal pain. The abdominal ultrasonography and computed tomography (CT) showed 2 cyst-like tumors, with hydatid features: one affecting the eighth liver segment and the other located at the upper pole of the spleen. We performed the surgical intervention using a laparoscopic approach, with an uneventful postoperative follow-up and the patient was discharged home on postoperative day 4. The postoperative images at 6 and 12 months showed a decrease in size of the remnant cystic cavities.

Thoracoscopic and laparoscopic esophagectomy with cervical manual anastomosis for esophageal cancer.

Evidence on the benefits of minimally invasive approach over traditional open procedure in gastrointestinal surgery is continuing to accumulate. This is also the case for esophageal surgery.Although laparoscopic esophageal surgery was initially reserved for benign pathology, the technical development, increasing experience with laparoscopic and thoracoscopic techniques and the theoretical advantages of minimally invasive surgery have widened the scope of minimally invasive approach to esophageal cancer. The surgical treatment of esophageal cancer often requires extensive procedures and is therefore, considered one of the most challenging and invasive procedure of gastrointestinal surgery. While transhiatal and transthoracic esophagectomy are common approaches for esophageal resection, data regarding the combined thoracoscopic and laparoscopic approach to esophagectomy are limited. The minimally invasive technique of esophagectomy to be described consists of three phases: thoracoscopic esophageal mobilization and mediastinal lymphadenectomy followed by laparoscopic gastric mobilization, abdominal lymphadenectomy and gastric conduit formation and finally retrieval of the resection specimen followed by an esophagogastric anastomosis via a left cervical incision.

Laparoscopic low anterior resection with total mesorectal excision for rectal cancer.

Rectal resections are the only treatment with curative intent currently accepted world wide. When performed in elective circumstances, laparoscopic rectal excision is technically feasible in surgical approach of mid-rectal cancer in a considerable number of patients. There are many benefits of the laparoscopic approach to rectal resection such as short hospitalization, less pain, less postoperative complications and improved quality of life. However, one mandatory condition in laparoscopic resection of rectum includes complete excision of the rectum and mesorectum, generally ensuring a minimal distal margin of 2cm and circumferential radial clearance before performing a coloanal anastomosis. Here, we present a laparoscopic approach for rectal cancer treatment consisting in a wide resection of the rectum, including the entire fascia with the enclosed mesentery of the rectum.
