Impact of Systemic Treatments on Outcomes and Quality of Life in Patients with RAS-Positive Stage IV Colorectal Cancer: A Systematic Review. Diseases 2024; 12:79. [PMID: 38667537 PMCID: PMC11049632 DOI: 10.3390/diseases12040079] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/17/2024] [Accepted: 04/19/2024] [Indexed: 04/28/2024] Open
Abstract
This systematic review critically evaluates the impact of systemic treatments on outcomes and quality of life (QoL) in patients with RAS-positive stage IV colorectal cancer, with studies published up to December 2023 across PubMed, Scopus, and Web of Science. From an initial pool of 1345 articles, 11 relevant studies were selected for inclusion, encompassing a diverse range of systemic treatments, including panitumumab combined with FOLFOX4 and FOLFIRI, irinotecan paired with panitumumab, regorafenib followed by cetuximab ± irinotecan and vice versa, and panitumumab as a maintenance therapy post-induction. Patient demographics predominantly included middle-aged to elderly individuals, with a slight male predominance. Racial composition, where reported, showed a majority of Caucasian participants, highlighting the need for broader demographic inclusivity in future research. Key findings revealed that the addition of panitumumab to chemotherapy (FOLFOX4 or FOLFIRI) did not significantly compromise QoL while notably improving disease-free survival, with baseline EQ-5D HSI mean scores ranging from 0.76 to 0.78 and VAS mean scores from 70.1 to 74.1. Improvements in FACT-C scores and EQ-5D Index scores particularly favored panitumumab plus best supportive care in KRAS wild-type mCRC, with early dropout rates of 38-42% for panitumumab + BSC. Notably, cetuximab + FOLFIRI was associated with a median survival of 25.7 months versus 16.4 months for FOLFIRI alone, emphasizing the potential benefits of integrating targeted therapies with chemotherapy. In conclusion, the review underscores the significant impact of systemic treatments, particularly targeted therapies and their combinations with chemotherapy, on survival outcomes and QoL in patients with RAS-positive stage IV colorectal cancer, and the need for personalized treatment.

The Predictive Role of Serum Lipid Levels, p53 and ki-67, According to Molecular Subtypes in Breast Cancer: A Randomized Clinical Study. Int J Mol Sci 2024; 25:3911. [PMID: 38612725 PMCID: PMC11012133 DOI: 10.3390/ijms25073911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Revised: 03/25/2024] [Accepted: 03/26/2024] [Indexed: 04/14/2024] Open
Abstract
Dyslipidemia is a component of metabolic syndrome, having an important role in the carcinogenesis of different tumor types, such as prostate, ovarian, or renal cancer. The number of studies on the predictive potential of the different components of the lipid profile with a predictive potential in breast cancer is quite low. The evaluation of the lipid profile was carried out for the 142 patients who benefited from neoadjuvant therapy (NAC) in order to identify a potential predictive biomarker. The serological sample collection was performed sequentially according to a standardized protocol, pre-NAC, post-NAC and 6 months post-NAC after a 6-h pre-collection fast. We also investigated in the general group the presence or absence of the p53 mutation (TP53) and of the mitotic index ki-67, respectively, in relation to the molecular subtypes. The menopausal status, tumor size, family history, grading, Ki-67, p53 and LN metastases have a predictive nature regarding overall survival (OS) (p < 0.05), while for disease free survival (DFS), only tumor size, tumor grading, Ki-67 > 14, and p53+ are of predictive nature. The genetic and molecular analysis carried out in our group indicates that 71.67% have a Ki-67 score higher than 14%, and 39% of the patients have the positive P53 mutation. The multivariate analysis in the case of patients included in the TNBC subtype showed that the increased tumor volume (p = 0.002) and increased level of HDL (p = 0.004) represent predictive factors for the tumor response rate to NAC. High HDL-C levels before NAC and increased LDL-C levels after NAC were associated with the better treatment response in ER-positive and HER2+ breast cancer patients. Increased HDL-C values and tumor volume represent predictive factors as to the response rate to NAC in the case of patients included in the TNBC subtype. Regarding the ER+ and HER2+ subtypes, increased levels of HDL-C pre-NAC and increased levels of LDL-C post-NAC were associated with a better therapeutic response rate. Tumor grading, Ki-67, p53, and LN metastases have a predictive nature for OS, while tumor size, tumor grading, and Ki-67 > 14, and p53+ are predictive for DFS.

Colorectal Cancer Risk Prediction Using the rs4939827 Polymorphism of the SMAD7 Gene in the Romanian Population. Diagnostics (Basel) 2024; 14:220. [PMID: 38275467 PMCID: PMC10814119 DOI: 10.3390/diagnostics14020220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2023] [Revised: 01/13/2024] [Accepted: 01/15/2024] [Indexed: 01/27/2024] Open
Abstract
Colorectal cancer (CRC) is globally recognized as a prevalent malignancy known for its significant mortality rate. Recent years have witnessed a rising incidence trend in colorectal cancer, emphasizing the necessity for early diagnosis. Our study focused on examining the impact of the SMAD7 gene variant rs4939827 on the risk of colorectal cancer occurrence. The composition of our study group included 340 individuals, comprising 170 CRC diagnosed patients and 170 healthy controls. We performed genotyping of all biological samples using the TaqMan assay on the ABI 7500 Real-Time PCR System (Applied Biosystems, Waltham, MA, USA). This investigation focused on the rs4939827 gene variant, assessing its association with CRC risk and clinicopathological characteristics. Genotyping results for the SMAD7 gene variant rs4939827 revealed a 42.6% prevalence of the C allele in CRC patients (p = 0.245) and a 22.8% prevalence of the T allele in control subjects (p = 0.109). This study concluded that there was an elevated risk of CRC in the dominant model for CC/CT+TT, with a p-value of 0.113 and an odds ratio (OR) of 2.781, within a 95% confidence interval (CI) of 0.998 to 3.456. The findings of our research indicate a correlation between variants of the SMAD7 gene and the likelihood of developing colorectal cancer in our study population. Consequently, these results could be instrumental in facilitating early diagnosis of colorectal cancer utilizing information on single-nucleotide polymorphism (SNP) and genetic susceptibility to the disease.

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries. Br J Surg 2024; 111:znad330. [PMID: 38743040 DOI: 10.1093/bjs/znad330] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 08/31/2023] [Accepted: 09/15/2023] [Indexed: 05/16/2024]
Abstract
BACKGROUND Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide. METHODS This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters. RESULTS A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien-Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries. CONCLUSION Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761).

VRAM Flap for Pelvic Floor Reconstruction after Pelvic Exenteration and Abdominoperineal Excision. J Pers Med 2023; 13:1711. [PMID: 38138938 PMCID: PMC10744748 DOI: 10.3390/jpm13121711] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Revised: 12/01/2023] [Accepted: 12/05/2023] [Indexed: 12/24/2023] Open
Abstract
Due to the still large number of patients diagnosed with pelvic neoplasms (colorectal, gynecological, and urological) in advanced stages right from the initial diagnosis, surgery represents the mainstay of treatment, often implying wide, eventually multi-organ resections in order to achieve negative surgical margins. Perineal wound morbidity, particularly in extralevator abominoperineal excision, leads to complications and local infection rates of up to 40%. Strategies to reduce postoperative wound complications are being pursued to address this issue. The VRAM flap remains the gold standard for autologous reconstruction after pelvic oncological resection; it was initially designed for abdominal wall defects and later expanded for large pelvic tissue defects. The flap's application is based on its physical characteristics, including abundant tissue and a generous skin paddle, which effectively obliterates dead space after exenterations. The generous skin paddle offers good cosmetic and functional outcomes at the recipient site. This article describes the case of a patient histopathologically diagnosed with stage IIIA squamous cell carcinoma of the uterine cervix who received multimodal onco-surgical treatment. The surgical mainstay of this treatment is pelvic exenteration. Pelvic reconstruction after this major surgery was performed using a vertical flap with the rectus abdominis.

Three-Year Analysis of the Rectal Cancer Care Trajectory after the COVID-19 Pandemic. Diseases 2023; 11:181. [PMID: 38131987 PMCID: PMC10742543 DOI: 10.3390/diseases11040181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Revised: 12/07/2023] [Accepted: 12/09/2023] [Indexed: 12/23/2023] Open
Abstract
The global pandemic period from 2020 to 2022 caused important alterations in oncology care. This study aimed to describe the trends and variations in patient characteristics, comorbidities, and treatment approaches during this time in Romania. We conducted a retrospective database search to identify patients with rectal cancer who underwent surgical intervention between 2020 and 2022 and the year 2019, which served as a pre-pandemic period control. This study included 164 patients, with a yearly increase of approximately 10% in surgical interventions noted from 2020 (1709 interventions) to 2022 (2118 interventions), but an overall 34.4% decrease compared with the pre-pandemic period. Notable shifts were observed in the type of surgeries performed, with laparoscopic procedures doubling from 2020 (25%) to 2022 (47.5%), confirming the decrease in emergency presentations during the last year of the COVID-19 pandemic and a recovery to normality with planned, elective interventions. Elective interventions increased significantly in 2022 (79.7%) compared with the previous years (p = 0.043), with a concurrent rise in neoadjuvant therapy uptake in 2022 (35.6%). However, significant alterations in the TNM staging, from 12.5% stage IV cases in 2020 to 25.4% in 2022 (p = 0.039), indicated an increased diagnosis of advanced stages of rectal cancer as the years progressed. There was a significant difference in albumin levels over the years (p = 0.019) and in the American Society of Anesthesiology (ASA) scores (from 6.2% ASA stage IV in 2020 to 16.9% in 2022), denoting an increase in case complexity (p = 0.043). This study reveals a trend of increasing surgical interventions and the prevalence of more advanced stages of rectal cancer during the pandemic years. Despite the subtle fluctuations in various patient characteristics and treatment approaches, notable shifts were documented in the severity at diagnosis and surgery types, pointing toward more advanced disease presentations and changes in surgical strategies over the period studied. Nevertheless, the trends in ICU admission rates and mortality did not alter significantly during the pandemic period.

The Value of Tumor Infiltrating Lymphocytes (TIL) for Predicting the Response to Neoadjuvant Chemotherapy (NAC) in Breast Cancer according to the Molecular Subtypes. Biomedicines 2023; 11:3037. [PMID: 38002037 PMCID: PMC10669335 DOI: 10.3390/biomedicines11113037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Revised: 10/28/2023] [Accepted: 11/01/2023] [Indexed: 11/26/2023] Open
Abstract
INTRODUCTION The antitumor host immune response is an important factor in breast cancer, but its role is not fully established. The role of tumor infiltrating lymphocytes (TIL) as an immunological biomarker in breast cancer has been significantly explored in recent years. The number of patients treated with neoadjuvant chemotherapy (NAC) has increased and the identification of a biomarker to predict the probability of pCR (pathological complete response) is a high priority. MATERIALS AND METHODS We evaluated 334 cases of BC treated with NAC followed by surgical resection from 2020-2022 at the Ist Clinic of Oncological Surgery, Oncological Institute "Prof Dr I Chiricuta" Cluj Napoca. Of the above, 122 cases were available for histological evaluation both in pre-NAC biopsy and post-NAC resection tissue. Evaluation of biopsy fragments and resection parts were performed using hematoxylin eosin (H&E). The TIL evaluation took place according to the recommendations of the International TIL Working Group (ITILWG). RESULTS There was a strong association between elevated levels of pre-NAC TIL. At the same time, there is a statistically significant correlation between stromal TIL and tumor grade, the number of lymph node metastases, the molecular subtype and the number of mitoses (p < 0.005). Intratumoral TIL showed a significant correlation with tumor size, distant metastasis, molecular subtype, number of mitosis, stage and lymph node metastasis (p < 0.005). We also demonstrated that high pre-NAC STIL represents a strong predictive marker for pCR. CONCLUSION This study reveals the role of TIL as a predictive biomarker in breast cancer not only for the well-established TNBC (triple negative breast cancer) and HER2+ (Her2 overexpressed) subtypes but also in Luminal A and B molecular subtypes. In this scenario, the evaluation of sTIL as a novel predictive and therapy-predicting factor should become a routinely performed analysis that could guide clinicians when choosing the most appropriate therapy.

Abstract
Introduction: Endometrial cancer is the most common form of gynecological cancer in developed countries. Current recommended therapeutic management takes into account a number of factors such as: TNM stage, justification for primary surgery, desire to preserve fertility. For primary operable cases, surgical staging has become an extremely important pillar, in which the status of the pelvic lymph nodes needs to be known (1-3). Material and Method: Between August 2015 and June 2021, a multicenter prospective observational study was performed in the "Prof. Dr. I. Chiricuta" Oncological Institute Cluj Napoca, 2nd Department of Surgery of "Pius Brinzeu" County Hospital Timisoara, 1st Department of General Surgery of Arad County Hospital, 2nd Department of Obstetrics and Gynecology "Dominic Stanca" Cluj Napoca and "Dr. Carol Davila" Central Military Emergency University Hospital Bucharest, Romania with the main aim of examining the sentinel lymph node detection rate using methylene blue as a tracer. Surgeries were performed by the team of surgeons of the mentioned clinics, and patients were informed about this study and signed an informed consent form for enrollment. Results: A total of 116 cases met the inclusion criteria for this prospective study. The mean age of the included patients was 62.3 years (minimum - 38, maximum - 83). The mean body mass index was 31.8 (minimum - 19.9, maximum - 48.2). In terms of histological type of the endometrial cancer, the majority of cases were endometrioid cancer, amounting to 72.5% of the total (n=84). A considerable number of cases were of mixed type, either with clear cell carcinoma (8.6%, n=10) or mixed carcinosarcoma (17.2%, n=20). The preferred approach for surgery was laparoscopic surgery rather than traditional surgery (72% vs 28%). Another element investigated from a histological point of view is the tumour grading, the degree of differentiation of cells with anarchic development, we note that 50% (n=58) were G2. Of the 116 cases of endometrial carcinoma included in the study, in 83% of cases (n=96) methylene blue tracer injection was successful and sentinel node was identified. The SLN technique continues to be of great interest and use in surgical centers around the world. The method of detecting sentinel lymph nodes varies depending on the individual. According to literature studies, indocyanine (ICG- Indocyanine green) is the gold standard for lymph node mapping, with superior detection rates when compared to other existing versions. Another key factor to consider when selecting a sentinel node identification method is cost-effectiveness. The use of methyl blue as a marker tracer is the most cost-effective option with equivalent detection rate outcomes. Conclusions: Based on the results of our study and other studies in the literature, lymphatic mapping using methylene blue as a tracer in endometrial cancer is a cost-effective method with a favourable detection rate. With this low-cost procedure we can achieve a correct tumor staging, avoiding overtreatment. There are multiple ways to identify the sentinel node using different tracers with higher accuracy, but the objective of the study was not to make a comparison between different tracers, but to present the feasibility of lymph node mapping using methylene blue as a low cost tracer with good reproducibility, short learning curve and optimal detection rate.

Acute Acalculous Cholecystitis Associated with Abscesses-An Unknown Dual Pathology. Biomedicines 2023; 11:biomedicines11020632. [PMID: 36831168 PMCID: PMC9953605 DOI: 10.3390/biomedicines11020632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2023] [Revised: 02/08/2023] [Accepted: 02/15/2023] [Indexed: 02/22/2023] Open
Abstract
(1) Introduction and Aims: Little is known about the relationship between renal pathology and gallbladder pathology, although the two organs (the gallbladder and the right kidney) are in close proximity to one another. If a renal abscess disseminates, the gallbladder would be one of the secondary organs involved. As the bile provides a favorable environment for the development of pathogenic germs, it allows for the development of acute cholecystitis, even if calculi are absent, thus resulting in the development of acute acalculous cholecystitis. The aim of our study was to analyze the association between acute acalculous cholecystitis (AAC) and renal abscesses. (2) Methods: A department-wide retrospective cohort observational study including 67 patients with renal abscesses, with a mean age of 34.5+/-16.21 years and with five males and 62 females, was conducted. All of the patients were examined by an abdominal ultrasound. The lab tests included CBC with differential liver enzymes and serum bilirubin (in order to assess alterations in the liver function which can be associated with AAC) and serum creatinine (in order to assess the renal function). Blood culture and urine culture tests were also performed. (3) Results: Of the 67 patients with renal abscesses, eight (11.94%) were associated with acute cholecystitis: four cases (5.97%) of acalculous cholecystitis and four cases (5.97%) of calculous cholecystitis, two of which presented biliary sludge (acute micro-calculous cholecystitis). All four cases of acute acalculous cholecystitis presented with sepsis, and there was one case of septic shock at onset. We did not observe an impairment in renal function in the patients presenting with acute acalculous cholecystitis, and hepatic impairment was inconstant and moderate. All of the cases had a favorable outcome after a prompt initiation of intensive antibiotic therapy; both the renal abscess and the acute acalculous cholecystitis receded without further complications. (4) Conclusions: The association of acute acalculous cholecystitis with renal abscesses could be related to the possibility of germ dissemination from the infectious focus. In the case of a renal abscess, careful clinical, lab, and imaging exams of the gallbladder are recommended in order to ensure early therapeutic intervention in the event of an association with acute acalculous cholecystitis.

The Challenges of Colorectal Cancer Surgery during the COVID-19 Pandemic in Romania: A Three-Year Retrospective Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:14320. [PMID: 36361200 PMCID: PMC9658781 DOI: 10.3390/ijerph192114320] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 10/27/2022] [Accepted: 10/31/2022] [Indexed: 06/16/2023]
Abstract
The predictions on the influence of the SARS-CoV-2 pandemic on access to medical services in Romania predicted a 35% drop in oncological hospitalizations in 2020 compared to the previous decade, raising the hypothesis that patients with colorectal cancer can become indirect victims of the ongoing pandemic. Therefore, the aim of the current research was to observe how the COVID-19 pandemic influenced colorectal cancer surgery in Romania, to determine the level of addressability towards specialized care, to compare the cancer staging between the pandemic and pre-pandemic periods, and to observe the risk factors for disease progression. This retrospective study was spread over three years, respectively, from March 2019 to March 2022, and included a total of 198 patients with a history of colorectal cancer surgery. It was decided to perform a parallel comparison of 2019, 2020, and 2021 to observe any significant changes during the pandemic. Our clinic encountered a significant decrease in all interventions during the pandemic; although the number of CRC surgeries remained constant, the cases were more difficult, with significantly more patients presenting in emergency situations, from 31.3% in 2019 to 50.0% in 2020 and 57.1% in 2021. Thus, the number of elective surgeries decreased significantly. The proportion of TNM (tumor-node-metastasis) staging was, however, statistically significant between the pre-pandemic and pandemic period. In 2019, 13.3% of patients had stage IIa, compared with 28.8% in 2020 and 13.1% in 2021. Similarly, the proportion of very advanced colorectal cancer was higher during the pandemic period of 2020 and 2021 (12.0% in 2019 vs. 12.5% in 2020 and 25.0% in 2021), which was represented by a significantly higher proportion of patients with bowel perforation. Patients with an advanced TNM stage had a 6.28-fold increased risk of disease progression, followed by lymphovascular invasion (HR = 5.19). However, the COVID-19 pandemic, represented by admission years 2020 and 2021, did not pose a significant risk for disease progression and mortality. In-hospital mortality during the pandemic also did not change significantly. After the pandemic restrictions have been lifted, it would be advisable to conduct a widespread colorectal cancer screening campaign in order to identify any instances of the disease that went undetected during the SARS-CoV-2 pandemic.

Abstract
BACKGROUND The aims of our study were to compare serum acylated ghrelin (the active form of ghrelin) concentrations before and after the surgery of patients undergoing laparoscopic sleeve gastrectomy (LSG) or laparoscopic greater curvature plication (LGCP) and to correlate these levels with excess weight loss and hunger sensations on a short-term basis. METHODS The patients included in the study had either (1) a body mass index (BMI) over 35 kg/m2 and one comorbidity or (2) a BMI over 40 kg/m2. Ghrelin levels were measured on the day of the surgery, 1 month after the procedure, and 3 months after the procedure. A questionnaire about hunger sensation was administered to the patients, and changes in the patients' weights were evaluated on the same timeline as the measurement of the ghrelin levels. RESULTS Eighteen obese patients were included in the study, including 10 patients in the LSG group and 8 patients in the LGCP group. All the procedures were performed laparoscopically. The average level of preoperative ghrelin in the LSG group was 212.21 pg/mL ± 140.57 SD. After 1 month, the average ghrelin level in the LSG group was 74.47 pg/mL ± 29.55 SD (p = 0.01), and it was 41.47 pg/mL ± 15.19 SD (p = 0.002) after 3 months. The average level of preoperative ghrelin in the LGCP group was 318.08 pg/mL ± 161.70 SD. It decreased to 190.58 pg/mL ± 116.75 SD (p = 0.01) after 1 month and to 91.57 pg/mL ± 56.70 SD (p = 0.004) after 3 months. Comparing the two groups, hunger sensation had decreased more in the LSG group (p = 0.03) 3 months after the surgery. CONCLUSIONS Laparoscopic sleeve gastrectomy (LSG) and laparoscopic greater curvature plication (LGCP) produced the same weight loss and diminished hunger sensation in the short term on the selected patients. LSG had an increased effect on ghrelin levels when compared with LGCP at 1 month after the procedure and 3 months after the procedure.

Plasma ghrelin, adiponectin and leptin levels in obese rats with type 2 diabetes mellitus after sleeve gastrectomy and gastric plication. Exp Ther Med 2021; 21:264. [PMID: 33603871 PMCID: PMC7851650 DOI: 10.3892/etm.2021.9695] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2020] [Accepted: 10/09/2020] [Indexed: 12/16/2022] Open
Abstract
The prevalence of obesity has increased in recent decades and has become a public health problem. In obesity patients the metabolism of almost all adipokines is markedly dysregulated. Studies regarding levels of ghrelin, leptin, and adiponectin after bariatric surgery reveal contradictory results. The purpose of the present study was to analyze modification of body weight and plasma levels of fasting glucose, ghrelin, adiponectin and leptin, in obese rats with T2DM after sleeve gastrectomy (SG), gastric plication (GP) and sham-operated (SO). Eighteen specimens where randomized to three weight-matched groups: Group SG underwent sleeve gastrectomy (n=6), group GP underwent gastric plication (n=6) and the control group SO underwent sham surgery (n=6). Upon surgery a normal rat chow diet (Bio-Serv® product no. F4031) was fed to the rats until the end of the experiment. Additional blood samples were harvested after 4 weeks. The results revealed that body mass decreased in the SG (783.17±101.39 vs. 658.33±86.57 g; P<0.0001) and the GP (781.33±103.12 vs. 702.33±84.06 g; P=0.004) rats after surgery. There were significant lower fasting glucose levels at 4 weeks postoperative in the SG group compared to the SO group (83.1±12.81 vs. 104.5±9.81 mg/dl; P=0.016). The same trend was observed in the GP group vs. the SO group (86.7±11.43 vs. 104.5±9.81 mg/dl; P=0.026). There was no difference regarding mean glucose levels between the SG group compared to the GP group (P>0.05). Plasma acylated ghrelin and leptin levels decreased four weeks after surgery compared to preoperative levels, while adiponectin levels increased four weeks after surgery in the SG and GP groups, respectively. The present study revealed that plasma glucose levels, ghrelin and leptin levels decreased after SG and GP, while adiponectin levels improved. This suggests that there may be hormonal contribution in weight loss.

Abstract
As the COVID-19 pandemic extends, its negative consequences on the effectiveness of therapeutic programs - previously assumed by the medical community and imperatively suspended for a difficult-to-predict period of time - are becoming increasingly worrying. In this context, as the evidence-based recommendations are not possible, most of the national and international scientific societies tried to develop balanced recommendations (1-4). The Romanian Society of Coloproctology (SRCP) and the Romanian Association for Endoscopic Surgery (ARCE) have created a working group that, taking into account recent publications, the statements of international academic societies, the national legislative context and the unique experience of countries severely affected by this pandemic (China, Italy, Spain, USA, etc.) proposes for Romania, the following recommendations for medical practice in colorectal surgery during the COVID-19 pandemic. These recommendations are subjected to continuous review, depending on the global and national situation of the pandemic, the particular needs of each hospital, the recommendations of the competent authorities and the evolution of the literature that publishes the conclusions of ongoing clinical trials.

Abstract
The best timing of cholecystectomy on patients with acute gallbladder pathology is still unclearly defined. Some studies have reported that cholecystectomy during the index acute admission presents an increased morbidity rate, extended duration of stay and increased costs. The study below is aiming at finding the most accurate moment to practice the surgery when acute cholecystitis is confirmed. Consequently, 368 patients admitted to hospital from January 2013 to December 2015 with the diagnosis of acute cholecystitis (AC) who underwent cholecystectomy in the 2nd Department of Surgery, Emergency County Hospital, Timi�oara, Romania constituted the two lots. The cases were retrospectively identified, introduced into the database and the data were subsequently analyzed according to various parameters. The study results reveal that laparoscopic cholecystectomy (LC) in the first 24 hours is safe procedure on the majority of the cases. Also, our findings sustain that emergency cholecystectomy can reduce the length of hospital stay, having similar rates of conversion to open surgery, complications and outcome compared with a delayed operation.

Abstract
Colorectal cancer (CRC) is one of the leading causes of death among cancer patients in Romania. It is known as a heterogeneous disease, characterized by diversion in multiple molecular pathways during its evolutionary process. This research was focusing on the two biomarkers that are related to CRC, specifically Carcinoembryonic Antigen (CEA) and Carbohydrate Antigen 19-9 (CA 19-9). Being an integral part of a wider study, we explored the use of a novel platform to support the strictly controlled process of data collection on colorectal cancer cases. We collected data about the patients regarding baseline clinical parameters, medical history, important comorbidities, intraoperative findings and adverse events, tumor characteristics, histological findings and main laboratory data (blood cell count, serum protein electrophoresis, liver and kidney function tests, serum levels of CEA and CA19-9). The results suggest that these two biomarkers are useful preoperative indicators of local recurrences and prognosis in colorectal cancer. Increased levels of both tumor markers are correlated with an advanced stage of the disease and a poor prognosis. Finally, this study aims to provide the necessary infrastructure, geared towards efficient, safe and comprehensive clinical evaluation of CRC cases.

Abstract
Sleeve gastrectomy (SG) and gastric plication (GP) are surgical procedures providing weight loss through several mechanisms incompletely understood. Rat models allow the possibility of tight regulation of experimental conditions, making them the ideal candidates for animal models in bariatric surgery. The aim of this study was to compare the weight and metabolic changes between sleeve gastrectomy and gastric plication in a rat model with type 2 induced diabetes mellitus and obesity. Fifteen male Wistar rats were fed with DIO food (Bio Serv �F3282 - Mouse Diet, High Fat, Fat Calories -60%), after 36 weeks were allocated to the study three arms-SG, GP and sham operation (SO). Four weeks after the surgery the rats were weighted again. Blood tests were performed before surgery and four weeks after surgery searching for blood glucose, total cholesterol, HDL, triglycerides, and LDL. At the onset of the study, the rats were 9 weeks old and had an average body mass of 231.6g � 31.58. After 36 weeks of DIO, one day preoperatively body weight was 774.93g � 95.02. The preoperatively average of body weight in the SG group was 777.4g �104.66, 775.4 g �104.6 in the GP group, respectively 772g �79 in the SO group. 4 weeks after surgery the mean body weight in the SG group was 648.8g �99.09, in the GP group was 695.6g �99.09, respectively 825.4g �79.87 in the SO fed ad libitum group. There was a significant decrease of mean fasting glucose levels at 4 weeks postoperative in the SG group compared to the SO group (87.4mg/dL�8.73 versus 103.6 mg/dlL�4.66, p= 0.01). The same trend of mean fasting glucose was registered in the GP group versus the SO group (92.8 � 5.67 mg/dl vs 103.6 mg/dl � 4.66, p=0.01). Our study provides evidence of the positive effects of bariatric surgery for treating patients with morbid obesity associated with diabetes mellitus and dyslipidemia and the use of rats to study the mechanisms of weight reduction and metabolic changes in bariatric surgery.

Abstract
INTRODUCTION Perforations of the peptic ulcers (PPUs) are the most common cause of emergency surgery among the complications of the gastroduodenal ulcers and the leading cause for morbidity and mortality due to secondary peritonitis and sepsis. PPU is a condition in which laparoscopic perforation repair (LPR) is an optimal solution. It makes possible the identification of the perforation's site and allows closure of the perforation and the subsequent peritoneal lavage, as in an open repair (OR) but without the large upper mid-abdominal incision. The main objective of this review was to evaluate the latest reported results in the laparoscopic treatment of the PPU. EVIDENCE ACQUISITION Using PubMed and EMBASE databases between 1989 and June 2017 we did an extensive electronic literature search. The search terms used were "laparoscopic perforated peptic ulcer." Inclusion criteria were all the published studies that reported the outcomes of LPR and LPR compared with OR for PPU were included in the analysis. The exclusion criteria included animal or laboratory studies, pediatric surgery trials, papers reporting less than 30 cases of LPR, clinical trials without major outcomes, and other language then English. EVIDENCE SYNTHESIS There were 32 studies included, counting 3488 patients with LPR and 5208 with OR. OR patients had more frequent shock at admission and had a higher ASA risk class. LPR patients had shorter hospital stays with two days, morbidity (11.12% vs. 14.71% OR) and mortality (1.95% vs. 8.35% OR) were lower. Leakage was three times higher in LPR arm (2.18% vs. 0.79% OR). Conversion occurred in 4.18% overall. The three primary reasons for conversions were the size of the perforation, the inability to locate the perforation and technical difficulties. CONCLUSIONS LPR showed similar or better results than OR in terms of morbidity, mortality, operation time and hospital stay, caution is needed as the OR patients tend to be more shocked or with higher ASA at presentation. The higher leakage rate after LPR should be addressed in the training of the laparoscopic surgeons or other safety measures should be developed and employed.

Abstract
Background and Objectives: Open surgery has been the mainstay treatment for liver hydatidosis in the past. Today, for treatment of simple and uncomplicated cysts, we have a variety of choices: antihelmintic therapy, the PAIR (puncture, aspiration, injection, and respiration) technique, and the laparoscopic approach. We reviewed our series of 267 cases of hepatic hydatidosis submitted to surgery over a period of 20 years, from 1995 through 2014, comparing the results of these minimally invasive treatments. Methods: In 92 patients (25.7% of cases) who presented with complicated liver hydatid cysts, we performed open surgery. In 16.4% of cases (59 patients), we used a laparoscopic approach, and in 208 patients (57.9% of cases), we used the PAIR technique. All patients were monitored after surgery for a mean of 61.7 months (range, 16–127). Postoperative follow-up consisted of clinical examination, laboratory investigation, abdominal ultrasound, and magnetic resonance imaging. Results: Almost all patients (198, 95.2%) treated with the PAIR technique and 55 patients (93.2%) treated with the laparoscopic approach were cured. Six patients (2.8%) from the echo-guided puncture group had to undergo a repeat of the procedure because the cavity did not disappear after 2 years. In 4 patients (2%), we performed open surgery for 2 biliary fistulas and 2 hepatic abscesses. Four patients from the laparoscopic group needed additional procedures. Open surgery was necessary in 2 patients for a recurrence after 2 years; 1 patient had developed a liver abscess and the other had a biliary fistula. Conclusions: In conclusion, open surgery remains the viable option for complicated cysts, with biliary communication, with multiple daughter vesicles, or with calcified walls. For simple, uncomplicated hydatid cysts, both methods (the PAIR technique and laparoscopic procedure) are safe and efficient, with very good results and low morbidity rates.
