RESUMO

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.

RESUMO

Background: Pancreatic Ductal Adenocarcinoma (PDAC) is a pathology with a very poor prognostic, the only curative treatment option being surgery, in association with chemotherapy. This study aims to assess the influence that the use of a standardized pathology report after a pancreaticoduodenectomy (PD) has on the R1 margins rate and the impact that this has on long term survival. Material and Methods: We included 116 patients admitted to the Regional Institute of Gastroenterology and Hepatology Prof. Dr. O. Fodor Cluj Napoca, who underwent PD for PDAC (Pancreatic Ductal Adenocarcinoma) between January 2012 and May 2017. We divided them in two groups: 59 patients for which a nonstandardized histopathological protocol was used and 57 patients for which a standardized protocol was implemented. We considered a margin to be R1 when there were tumor cells at ¤ 1 mm from the resection margin. Results: The R1 percentage in the first group of patients was of 39%, while the R1 resection rate in the second group was of 68.4%. The median survival rate was similar in the two groups, with no statistically significant difference between them, but in the prospective study when comparing R0 vs R1 margins there was a statistically differences in 5 year OS with a p-value = 0.03. Conclusion: The use of a standardized pathology report reveals a significant increase in R1 resection rates. Also study revealed not only increasing R1 incidence when using a standardized histopathology report, but also that those margins (R1) playing a determinant role in 5-year OS. The mesopancreas is the most frequently R1 resection margin.

RESUMO

MicroRNAs (miRNAs) are molecules with a role in the post-transcriptional regulation of messenger RNA, being involved in a wide range of biological and pathological processes. In the present study, we aim to characterize the behavior of a few miRNAs with roles in the cell cycle and differentiation of colon cancer (CC) cells. The present work considers miRNAs as reflections of the complex cellular processes in which they are generated, their observed variations being used to characterize the molecular networks in which they are part and through which cell proliferation is achieved. Tumoral and adjacent normal tissue samples were obtained from 40 CC patients, and the expression of miR-29a, miR-146a, miR-215 and miR-449 were determined by qRT-PCR analysis. Subsequent bioinformatic analysis was performed to highlight the transcription factors (TFs) network that regulate the miRNAs and functionally characterizes this network. There was a significant decrease in the expression of all miRNAs in tumor tissue. All miRNAs were positively correlated with each other. The analysis of the TF network showed tightly connected functional modules related to the cell cycle and associated processes. The four miRNAs are downregulated in CC; they are strongly correlated, showing coherence within the cellular network that regulates them and highlighting possible approach strategies.

RESUMO

INTRODUCTION: Laparoscopic liver resections (LLRs) constitute an area of surgery that has been kept away from residents in their hands-on training. The aim of our study is to assess the feasibility and the value of a didactic "step-by-step" program for LLR performed by residents using the swine training model. METHODS: From May 2018 to November 2019, three hands-on workshops were held. The protocol involved the performance of cholecystectomy, liver mobilization, minor and major hepatectomies. The participants' performance results in terms of operative time, blood loss, conversion, trainers' intervention, and intraoperative mortality, were recorded. The first workshop was comprised of 30 residents who previously participated in laparoscopic surgery workshops. In the second workshop, after six residents dropped out due to residency completion, the findings for the remaining 24 residents were compared to those for 24 junior-attending surgeons who did not follow the protocol and had not performed LLR previously, and to another 24 residents in a third workshop, who had not taken the training program before but followed the protocol. RESULTS: All residents fully completed the surgical procedures. Trained residents achieved better operative times and less blood loss compared to junior-attending surgeons (p < 0.017), however, the remaining parameters were comparable. When compared to non-trained residents, those who underwent training achieved significantly better results only in operative times (p < 0.001). CONCLUSION: A continuous LLR "step-by-step" training program on swine for residents is feasible and the "step-by-step" protocol is a valuable tool for a proper surgical education.

RESUMO

BACKGROUND: The objective of our study is to develop an effective training platform for transanal endoscopic surgery and to validate a step-by-step training program for learning the basic skills necessary for this approach. METHODS: We have designed a two-part study: an experimental study (with the aim to design the training platform and the training exercises - on synthetic and biological material) and a prospective analytical study, in order to validate the training program by enrolling as participants general surgery residents and specialists, without previous experience in transanal endoscopic interventions. The performance of the participants was assessed based on the time of completion, as well as the quality of the execution. RESULTS: We have developed three different diameter platforms (5 cm, 7.5 and 10 cm), that can be used with both the TEO and TAMIS platforms; specific exercises were developed to train different surgical skills like manipulation of tissue, cutting, dissection and suturing. Forty participants were enrolled for the validation of the proposed training program (12 young residents, 16 senior residents and 12 specialist surgeons). A statistically significant improvement of the performance time, from round to round, was observed for all participants in all exercises. The time of completion for the exercises, considering the correct technical execution, was the shortest for more experienced surgeons: specialist surgeons, followed by senior residents and young residents. The biological material exercises, that closely recreate intraoperative conditions and had more strict technical requirements, were difficult to be performed by young residents; better completion rates were seen in senior residents, while all the participants in the specialist surgeons group have completed these exercises. CONCLUSIONS: Our training program is an effective simulation based educational model for recreating intraoperative conditions particular to transanal endoscopic surgery. The proposed step-by-step training program has demonstrated to be useful in developing the important basic skills needed for transanal endoscopic surgery and assured the progress of all the participants, regardless of their surgical experience.

RESUMO

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.

RESUMO

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.

RESUMO

Background: Pancreatic cancer represents the fifth leading cause of death in industrialized countries. The prognosis is reserved, surgical resection being the only curative treatment, but the complications associated bear important impact on the patients survival, prognosis, and quality of life. The ERAS protocols come to meet these shortcomings for enhanced recovery after major pancreatic resections. Material and method: A systematic review was performed following the guidelines outlined by The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Original articles published in the online databases Pubmed (Medline), Embase and Cochrane since 2017 until 2022 were screened after using specific keywords. Results: A total of 252 studies was obtained by searching through online databases. Following the exclusion criteria, we included 7 studies in the systematic review. Conclusions: The ERAS protocols are safe to be applied in the common practice. They are efficient in the perioperative management of patients undergoing pancreatic resections. They can further decrease hospitalization stay, promote better recovery of gastrointestinal function, and speed up postoperative recovery.

RESUMO

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.

RESUMO

Background: POSSUM and P-POSSUM are risk scores recommended by ERAS Society for the preoperative evaluation of patients undergoing major surgery. Methods: This study includes 113 consecutive pancreaticoduodenectomy performed in a single centre between July 2013-December 2015. Patients data were prospectively collected using Excel 2009 and retrospectively analysed with R v3.2.4 software. Biological status score, surgical severity score and risk scores for complications and death were calculated using: http://www.riskprediction. org.uk/index-pp.php. Results: Morbidity rate was 61,95%: 19,47% general complications, 14,16% wound infections and 28,32% PD specific complications (11,5% POPF; 8,85% DGE and 6,19% PPH). Comparing the observed and estimated morbidity and mortality, we obtained statistical significant results (p=0,05 and p=0,03, respectivelly). When we considered only specific PD complications and subsequent mortality, there was no longer significant difference between observed and estimated values (p=0,8 and p=0,86).The under ROC curve aria was 0,61 for morbidity and 0,64 for specific PD morbidity, respectively 0,61 for mortality and 0,68 for specific PD complications related mortality. CONCLUSION: P-POSSUM represents a useful tool for appreciating the complication and death risk after PD, but better results could be obtain by considering also specific PD risk factors.

RESUMO

Introduction: National databases for pancreaticoduodenectomies (PD) have contributed to better postoperative outcomes after such complex surgical procedure because the multicentre collection of data allowed more reliable analyses with quality assessment and further improvement of technical issues and perioperative management. The current practice and outcomes after PD are poorly known in Romania because there was no national database for these patients. Thus, in 2016 a national-intent electronic registry for PD was proposed for all Romanian surgical centers. The study aims to present the preliminary results of this national-intent registry for PD after one-year enrollment. Patients Methods: The database was started on October 1st, 2016. Data were prospectively collected with an electronic online form including 102 items for each patient. The registry was opened to all the Departments of Surgery from Romania performing PD, with no restriction. Results: During the first year of enrollment were collected the data of 181 patients with PD performed by 24 surgeons from four surgical centers. The age of patients was 64 years (28 - 81 years), with slightly male predominance (61.3%). Computed tomography was the main preoperative imaging investigation (84.5%). All the PDs were performed by an open approach. The Whipple technique was used in 53% of patients, and a venous resection was required in 14.3% of cases. A posterior approach PD was considered in 16.6% of patients. The stomach was used to treat the distal remnant pancreas in 50.1% of patients. The operative time was 285 min (110 - 615 min), and the estimated blood loss was 400 ml (80 - 3000 ml). The overall morbidity rate was 55.8%, with severe (i.e., grade III-IV Dindo-Clavien) morbidity rate of 10%, and 3.9% in-hospital mortality rate. The overall pancreatic fistula, delayed gastric emptying and hemorrhage rates were 19.9%, 39.8% and 15.5%. Periampullary malignancies were the main indications for PD (78.9%), with pancreatic cancer on the top (48%). Conclusions: To build a prospective electronic online database for PD in Romania appears to be a feasible project and a useful tool to know the current practice and outcomes after PD in our country. However, improvements are still required to encourage a larger number of surgical centers to introduce the data of patients with PD.

RESUMO

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.

RESUMO

PURPOSE: The main objective of this study was to compare the effect of two anaesthetic techniques (general vs combined) on plasma levels of NGAL (Neutrophil Gelatinase Associated Lipocalin) after robotic urogenital oncosurgery. The secondary objective was to correlate NGAL levels with the incidence of acute kidney injury (AKI). METHODS: This was a longitudinal prospective study. Forty patients were included and randomized in 2 groups: group C (N=16 cases; combined general-epidural anesthesia) and group G (N=24 cases; control group with general anesthesia). Demographic data, Charlson Comorbidity Index, Apache II, SOFA and ASA scores were similar in both groups. Serum creatinine was determined preoperatively and every 24 hrs for 4 postoperative days to identify AKI according to RIFLE and AKIN criteria. Serum NGAL was determined at 6 and 12 hrs after induction of anesthesia. RESULTS: Serum creatinine increased at 24 hrs postoperatively in both groups as compared to baseline, but significant changes were registered only in the G group (p(control) = 0.004). Serum NGAL increased significantly in both groups as compared with baseline levels (pcase=0.0034 vs p(control)=0.0001). The incidence of AKI was 12.50% (95% CI 0.4-34) in the C group and 37.50% (95% CI 17-58) in the G group (p=0.0909), respectively. CONCLUSION: Impaired renal function and AKI occurred in robot-assisted laparoscopic urogenital oncosurgery under both general and combined anaesthesia. The incidence of AKI was lower in patients undergoing combined anesthesia compared to general anaesthesia after robotic urogenital oncosurgery but the difference did not reach statistical significance. However, plasma levels of NGAL were significantly increased at 6 and 12 hrs in the general anaesthesia group as compared with combined anaesthesia. NGAL may be a better marker in detecting postoperative acute kidney injury. Further studies are needed.

RESUMO

Liver malignancies represent one of the major public health problems worldwide because of late diagnosis and failure of current treatments to offer a curative option for many of the patients. MicroRNAs (miRs) are small non-coding RNA molecules that are known to regulate the gene expression at a post-transcriptional level through complementary base pairing with thousands of messenger (m)RNAs. Recent data has shown the involvement of miRs in the pathogenesis of many human cancers, including those of the liver, with huge possible impact in the clinic, mainly due to the identification of non-coding RNAs as biomarkers that can often be detected in the systemic circulation. In the current review, we present the importance of miRs in liver cancers by discussing their role in the pathobiology of these diseases, apart from their role as diagnostic and prognostic markers for liver malignancies.

RESUMO

According to recent epidemiological studies, malignant diseases represent the second cause of mortality worldwide and metastasis is the main cause of morbidity and mortality in most cancers. Even if the concept of "cancer stem cells" (CSCs) was anticipated by the genius of Rudolph Virchow, the father of modern pathology, more than 150 years ago, it is only in last few years that that scientists have begun to develop strategies aimed at inhibiting CSCs at a molecular level, the only way cancer can truly be attacked, by crossing the border between histology and molecular biology. The current concise review aims at emphasizing the main characteristics of tumor initiating cells, bridging the basic science to clinical hematology and oncology.

RESUMO

Pancreatic cancer is one of the most aggressive, heterogeneous, and fatal types of human cancer; therefore, more effective therapeutic drugs are urgently needed. Human epidermal growth factor receptor 2 (HER2) overexpression and amplification have been identified as a cornerstone in this pathology. The aim of this review is to identify HER2 membrane overexpression in relation to pancreatic cancer pathways that can be used in order to develop a targeted therapy. After searching the keywords, 174 articles were found during a time span of 10 years, between 2013 and 2023, but only twelve scientific papers were qualified for this investigation. The new era of biomolecular research found a significant relationship between HER2 overexpression and pancreatic cancer cells in 25-30% of cases. The variables are dependent on tumor-derived cells, with differences in receptor overexpression between PDAC (pancreatic ductal adenocarcinoma), BTC (biliary tract cancer), ampullary carcinoma, and PNETs (pancreatic neuroendocrine tumors). HER2 overexpression is frequently encountered in human pancreatic carcinoma cell lines, and the ERBB family is one of the targets in the near future of therapy, with good results in phase I, II, and III studies evaluating downregulation and tumor downstaging, respectively.

RESUMO

BACKGROUND: In the context of gastric cancer, surgical resection stands as the sole curative treatment. Central to influencing overall survival are the resection margins. This research aims to identify the factors influential in determining microscopically positive resection margins (R1) and to evaluate overall survival. METHODS: Our study encompassed 549 patients diagnosed with adenocarcinoma of the stomach who underwent curative-intent surgery between January 2011 and December 2021 in our Surgery Department. We investigated the incidence of positive margins (R1) and their impact on survival rates, as well as the determinants of R1. The standardization of R1 involved ensuring a margin distance of less than 1 mm from the tumor line to the margin. RESULTS: The incidence of R1 margins was 13.29% (73 patients). Among these, proximal R1 margins were observed in 29 patients (39.72%), while 49 cases (67.12%) presented circumferentially positive margins, with 20 cases (27.39%) exhibiting distally positive margins. Nineteen patients (26.02%) had two R1 margins, and 3 patients had all resection margins microscopically positive (4.10%). Factors such as tumor dimension, invasion of other organs, pT stage, pN stage, pL1 stage, pV1 stage, pPn stage, Lauren type, and tumoral grading demonstrated significance (p < 0.01) in the occurrence of positive R1 margins. CONCLUSION: Tumor dimension, invasion of other organs, pT stage, pN stage, pL1 stage, pV1 stage, pPn stage, Lauren type, and tumoral grading could be regarded as factors for predicting microscopically positive margins. Moreover, positive resection margins have a detrimental impact on overall survival.

RESUMO

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.

RESUMO

BACKGROUND AND AIMS: In the last years increasing scientific evidence drew attention on the potential effects of anesthetic drugs on postoperative outcome in cancer patients. Local anesthetics, especially lidocaine, have been intensively studied in relation with postoperative outcome in colorectal cancer patients. Our study objectives were to investigate the effects of perioperative intravenous lidocaine infusion on neutrophil-to-lymphocyte ratio and short-term postoperative outcome. Additionally, we also looked at 1 year outcome after intended radical colorectal cancer surgery. METHODS: 150 patients scheduled for colorectal cancer surgery were randomized to receive sevoflurane anaesthesia with or without 48 hours lidocaine infusion. RESULTS: 73 patients were included in the group A (sevoflurane) and 77 in the group B (sevoflurane with lidocaine). Lidocaine infusion did not modify neutrophil-to-lymphocyte ratio at 24 hours after surgery (p=0.58). Patients receiving intravenous lidocaine had significantly lower morphine consumption (p=0.04), faster mobilization time (p=0.001) and fewer days spent in the hospital (p=0.04). Moreover, at 1 year follow- up, patients in group B had a significant decreased rate of recurrences (p=0.03). There was no significant difference in 1 year survival (p=0.22). CONCLUSIONS: In our study, intravenous lidocaine infusion hastened the postoperative recovery of patients in terms of mobilization, hospital discharge and opioid consumption and reduced 1 year recurrence rate. Further studies on larger groups of patients are needed.

RESUMO

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.
