RESUMO

The newly identified refractory adult-onset autoinflammatory syndrome known as VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is brought on by somatic mutations in the ubiquitin-like modifier-activating enzyme 1 (UBA1) gene in hematopoietic stem and progenitor cells that change the expression of the UBA1 isoform. As a result, patients have a variety of hematologic and systemic inflammatory symptoms. All types of medical professionals should treat VEXAS syndrome seriously due to the high fatality rate. To better comprehend the condition and enhance the prognosis for VEXAS syndrome, this review article describes the essential traits and clinical signs of the condition. The discussion of future directions in the study of systemic inflammatory disorders brought on by somatic mutations concludes.

RESUMO

Background: The objective of this paper is to highlight the role and place of ileostomy from the perspective of the risk of anastomotic leakage (AL). Materials and method: This was a retrospective study of 74 (46.54%) low and ultra-low anterior resections from 159 cases of rectal cancer operated on in a seven-year interval (2015 - 2021). The cases were divided into two groups: Group A with protective ileostomy (47 cases = 63.51%) and Group B without protective ileostomy (27 cases = 35.49%). Results: The type of anastomosis was low colorectal for 15 cases and ileorectal for two cases, both in Group A, with either mechanical or manual sutures. Continuous loop ileostomy was the only fecal diversion procedure used for protection. The ileostomy-specific complications recorded in Group A were peristomal skin lesions (8 cases), early peristomal hernia (2 cases), and severe dehydration with acute renal-insufficency (7 cases). The closure of the ileostomy was performed in 42 cases (89.36%), with the time between the primary operation and the closure being 4.28 months on average, with limits between 12 days and 10 months. AL treatment was conservative in 13 (76.47%) cases and surgical in four cases, with the types of operations performed at reintervention being take-down of the anastomosis + left terminal colostomy + ileostomy closure in three cases (2 in Group A and 1 in Group B) and terminal ileostomy in one case in Group A. Conclusions: To reduce its specific complications, ileostomy should be performed in well-selected patients. Those with risk factors for leakage include males, the elderly, and those having important comorbidities, neoadjuvant chemoradiotherapy, low tumors below 5 cm from the anal verge, or complete circumferential stenosis and peritumoral inflammatory infiltrate.

RESUMO

Background: This study sought to investigate the diagnostic procedures, treatment modalities, and consequences of anastomotic leakage (AL) in low anterior resection rectal cancer patients. Methods: A retrospective analysis was conducted on 186 patients consecutively admitted and treated in the 1st Department of Surgery in Craiova, between January 2018 and June 2022, all of whom had undergone surgical interventions for adenocarcinoma of the rectum. Among this cohort, 106 patients who had undergone scheduled low and ultralow anterior rectal resections with total mesorectal excision were selected for further analysis. Twenty-four patients were diagnosed with postoperative AL and underwent diverse management strategies based on the severity of their condition. Results: The study revealed an incidence of 22.6% for postoperative AL, with all of them being classified as grade B and C, according to the 2010 International Study Group of Rectal Cancer Classification, which were associated with significant morbidity and mortality. Notably, patients exhibited various comorbidities, including obesity, arterial hypertension, type 2 diabetes mellitus, and kidney failure. The management approach depended on the severity of the clinical presentation and the availability of treatment options. Early diagnosis and conservative management constituted the initial therapeutic strategy for grade B AL, with surgical reintervention or transanal vacuum therapy being used in grade C AL. Conclusions: The incidence and mortality associated with AF following low anterior resections were notably elevated. Grade B AL were successfully managed through conservative treatment, whereas grade C AL required either surgical reintervention for drainage or diversion procedures, or transanal vacuum therapy.

RESUMO

The aim of this study was to assess the role of immunocyte-derived ratios (IDRs), such as the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR), as markers for the postoperative recovery of gastrointestinal function following colorectal cancer surgery. A retrospective analysis was conducted on a consecutive cohort of 260 patients who underwent radical colorectal cancer surgery within the timeframe spanning from January 2016 to December 2022. Data concerning the postoperative recovery of gastrointestinal function included the I-FEED score, time to pass flatus, toleration for liquids in the first 48 h, and the need for nasogastric tube reinsertion in the immediate postoperative period. A special emphasis was allocated towards the examination of IDRs and their interrelation with the postoperative gastrointestinal functional parameters. The I-FEED score exhibited a positive correlation with the NLR, SII, and PLR. The univariate analysis indicated that all IDRs, multiorgan resection, hemoglobin and protein levels, regional nodal extent of the tumor (N), and obesity significantly affected nasogastric tube reinsertion. The multivariate analysis showed that the SII and N1 stages were risk factors for nasogastric tube reinsertion after colorectal cancer surgery. The SII and multiorgan resection were the only classifiers that remained significant in the multivariable analysis for the toleration for liquids. In summation, certain preoperative IDRs, such as the SII, PLR, and NLR, may hold potential as predictive determinants for postoperative gastrointestinal functional recovery following colorectal cancer surgery.

RESUMO

Schwannoma is a tumor that originates from the Schwann cells that surround a neuron's axon. This tumor is very rare in the gastrointestinal tract and develops submucosally from intestinal nerve plexuses. The most common location for gastrointestinal schwannomas is the stomach, where they account for only 0.2% of gastric tumors. We present the case of a 56-year-old asymptomatic patient who was diagnosed, following a routine ultrasound examination, with an abdominal tumor. An abdominal MRI confirmed the gastric origin of the tumor. Although a subsequent upper-digestive endoscopic ultrasound was performed, a definitive diagnosis could not be established. Thus, a laparoscopic wedge resection of the stomach was performed. The immunohistochemical examination of the tumor established the diagnosis of benign schwannoma. Despite the availability of advanced endoscopy and imaging techniques, the diagnosis of gastric schwannoma is very rarely preoperative. The immunohistochemical identification of S-100 on the surgical specimen confirmed the diagnosis.

RESUMO

We aimed to comparatively assess the prognostic preoperative value of the main peripheral blood components and their ratios-the systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-monocyte ratio (LMR), and platelet-to-lymphocyte ratio (PLR)-to the use of artificial-neural-network analysis in determining undesired postoperative outcomes in colorectal cancer patients. Our retrospective study included 281 patients undergoing elective radical surgery for colorectal cancer in the last seven years. The preoperative values of SII, NLR, LMR, and PLR were analyzed in relation to postoperative complications, with a special emphasis on their ability to accurately predict the occurrence of anastomotic leak. A feed-forward fully connected multilayer perceptron network (MLP) was trained and tested alongside conventional statistical tools to assess the predictive value of the abovementioned blood markers in terms of sensitivity and specificity. Statistically significant differences and moderate correlation levels were observed for SII and NLR in predicting the anastomotic leak rate and degree of postoperative complications. No correlations were found between the LMR and PLR or the abovementioned outcomes. The MLP network analysis showed superior prediction value in terms of both sensitivity (0.78 ± 0.07; 0.74 ± 0.04; 0.71 ± 0.13) and specificity (0.81 ± 0.11; 0.69 ± 0.03; 0.9 ± 0.04) for all the given tasks. Preoperative SII and NLR appear to be modest prognostic factors for anastomotic leakage and overall morbidity. Using an artificial neural network offers superior prognostic results in the preoperative risk assessment for overall morbidity and anastomotic leak rate.

RESUMO

INTRODUCTION: This study investigates the prognostic significance of carcinoembryonic antigen (CEA) levels in predicting early postoperative mortality in patients who have undergone colorectal cancer surgery. METHODS: Between 2017 and 2022, total of 325 patients were enrolled in the study, and their preoperative serum CEA levels were measured. Relevant clinical and operative data were extracted and correlations between CEA levels and postoperative mortality was analysed. RESULTS: Among the surgical cases, 180 patients (55.3%) exhibited elevated CEA levels. Within the early postoperative period of 30 days, 14 patients (4.3%) succumbed, comprising 8 cases (2.4%) of colon cancer and 6 cases (1.8%) of rectal cancer. Notably, only 3 cases (0.9%), consisting of 1 (0.3%) colon cancer and 2 (0.6%) rectal cancer cases, were associated with an elevated CEA level. However, no statistically significant correlations were observed between CEA levels and early postoperative mortality. CONCLUSIONS: Our findings indicate that increased CEA levels may not serve as a reliable non-invasive marker for identifying patients at high risk of early mortality in the context of colo-rectal cancer surgery.

RESUMO

Introduction: Gastrointestinal stromal tumors (GIST) are a rare form of cancer located within the gastrointestinal (GI) tract, defined as tumors with spindle, epithelioid, or occasionally pleomorphic cells. They originate in the interstitial cells of Cajal, with the function of "pacemaker" of gastrointestinal motility. Their behavior is dictated by changes in the c-kit/PDGFRA gene, which is often highlighted by immunolabeling. Methods: We report the clinical, macroscopic, microscopic, and immunohistochemical characteristics of consecutive patients diagnosed with GIST who underwent surgical removal of the tumor in our department between 2008-2022. Results: We included 20 consecutive patients. The presentation was considered a surgical emergency requiring immediate surgical intervention in most subjects. The most common localization is the small intestine (n=9, 45%), followed by the stomach (n=7, 35%), colon (n=3, 15%), and peritoneum (n=1, n=5%). Histologically, the tumors were predominantly mixed (n=10, 50%) followed by spindle type (n=8, 40%) and epithelioid - 2 cases (10%). Conclusion: The clinical presentation of GISTs remains heterogeneous, and the diagnosis is predominantly postsurgical, using complex immunohistochemistry analysis. The tumor size and number of mitoses are strongly associated with the long-term prognosis.

RESUMO

INTRODUCTION: Inguinal hernia is one of the most common conditions in surgical departments and diabetes is known to have a significant impact on both patients' health and healthcare system. The current study aims to evaluate extensively the differences in costs for different subgroups of diabetic patients undergoing inguinal hernia repair in a tertiary care medical center in South-West Romania. MATERIAL AND METHODS: A total number of 195 patients underwent hernia repair for primary or recurrent inguinal hernia between 2015 and 2020 and were included in the analysis. The group was divided into diabetic/non-diabetic patients and each of these subgroups was studied separately according to the presence or absence of comorbidities, sex and place of origin. RESULTS: Statistically significant differences were found in the division of the age group, highlighting the fact that in diabetic patients the average age was around 74.76 years, unlike those without diabetes in which the average age was approximately 61.31 years. Another statistically significant difference was observed in the classification by hospitalization days of the group of patients with incarcerated inguinal hernia, in a sense that diabetic patients required a prolonged hospitalization by 1.5 days as opposed to non-diabetics. CONCLUSIONS: The costs of hospitalization for diabetic patients undergoing hernia repair surgery were marginally higher than in non-diabetic patients, but no statistical difference could be observed between any of the costs subsets in the two patients groups.

RESUMO

The validation of histological prognostic markers in colorectal cancer not only for survival parameters but also for early postoperative outcomes is of paramount importance. The aim of our study was to search for the tumor histopathological (HP) characteristics that may influence the postoperative morbidity, especially the occurrence of anastomotic leakage. Our results indicated that peritumoral inflammatory cell infiltrate appeared to correlate with both anastomotic fistula and overall postoperative complications. Likewise, high-grade and undifferentiated colorectal tumors seemed to be correlated with a higher incidence of postoperative leakage and complications. No relation could be established between the other HP features and the postoperative untoward outcomes.

RESUMO

Introduction: The management of this type of trauma has evolved considerably, especially with the introduction of interventional radiology (angiography, splenic artery embolization - SAE) but also the concept of non-operative treatment (NOT), defined as a follow-up of injuries, without surgery. Material and Method: We have established a strategy for dealing with cases of abdominal trauma with injuries by non-operative treatment (NOT). We applied NOT to 13 patients in 50 (26%), of which 8 were patients with spleen injuries and 5 were patients with liver damage. Most of the lesions were grade II (8 cases), 2 cases were grade I and 3 cases were grade III. Results: There was only one case dealt by NOT, in which surgery was performed 48 hours after admission. In two patients with extravasation of the contrast agent on CT and angiography, angioembolization of the splenic artery was performed, with good results. Control CT was performed at a period that varied between 24 hours and 5 days after admission. The average period of hospitalization of patients approached by NOT was 6,6 days. Conclusions: Contrast-enhanced CT examination remains the basis for NOT initiation, providing the necessary data on the degree of liver or splenic lesion, the size of blood collections and extravasation of the contrast substance but is also the essential imaging exploration in assessing NOT efficacy. Angioembolization can be successfully performed in cases where CT examination and angiography show contrast extravasation. There was only one case included in the NOT, which was operated laparoscopically, but most authors emphasize that this should not be considered a failure of the method.

RESUMO

BACKGROUND: The COVID-19 pandemic has posed unprecedented challenges to health systems worldwide-in delivering care to patients and in maintaining training of their care providers. Surgical specialties have particularly struggled to maintain sufficient levels of training as we have seen significant reductions in the number of surgical beds, operating lists and redeployment of surgical staff to COVID-19 departments or Intensive Treatment Units. METHODS: Comparison of the number of surgical operations performed between January 1st 2019 and December 31st 2020 in 3 surgical departments in Romania (Craiova, Timisoara and Bucharest) and 1 surgical department in Thessaloniki, Greece. Cases were compared on a month to month basis, both elective and emergency operations were included and divided into three main categories based on severity (Minor, Medium, Major). RESULTS: Between 2019 and 2020, there was a 37.04% decrease in the number of surgical procedures, 36.95% for open procedures and 37.20% for laparoscopic procedures. Statistically significant overall reduction was observed in all three centers for both open and laparoscopic operations. In all centers, a statistically significant reduction in medium severity procedures was also observed. CONCLUSION: Globally felt detrimental effect on surgical training, patient contact and mental well-being reflected similarly across surgical specialties in both countries.

RESUMO

INTRODUCTION: Neutrophil/lymphocyte ratio (NLR) is known as a prognostic for the outcome of the patients with gastric cancer. As no definite risk marker for anastomotic leakage after gastric resection was identified, we investigated the possible role of NLR. METHODS: Peripheral blood count for neutrophils and lymphocytes was done at the patient's admission. We retrospectively evaluated 204 gastric cancer patients, who underwent gastric resection, comparing the values of NLR between the group of patients with anastomotic leakage and those without complications. RESULTS: Using the ROC curve, we found the cutoff value of NLR, which permitted the comparison of the group with low NLR, presenting increased NLR. The cutoff value for NLR was 3.54. Between the two groups, we could observe statistically significant differences in developing fistula (p < 0.01) and complications leading to death (p < 0.025). The odds ratio for patients with NLR greater than 3.54 to develop anastomotic leak was 17.62, compared to those with lower NLR. CONCLUSION: Peripheral blood NLR proved to be a predictor for anastomotic leakage.

RESUMO

Uncontrolled bleeding contributes to 30% to 40% of trauma-related deaths and is the leading cause of potentially preventable deaths. Currently, there is no effective method available to first responders for temporary control of noncompressible intraabdominal bleeding while patients are transported to the hospital. Our previous studies demonstrated that abdominal insufflation provides effective temporary bleeding control. The study aims to prove the feasibility (insufflation to a target pressure) and safety (cardiovascular and respiratory effects) of a novel portable abdominal insufflation device (PAID) designed to control the intraperitoneal bleeding caused by abdominal trauma. The PAID prototype is based on a patented design and manufactured via additive manufacturing. PAID contains a 16-g CO2 cartridge and an electronic pressure transducer. PAID was tested on a bench top and a swine animal model. For the animal model study, the intraperitoneal pressure as well as cardiorespiratory parameters (hearth rate, SpO2 [peripheral capillary oxygen saturation], and blood pressure) were continuously monitored during the insufflation procedure. The prototype functioned according to specifications on both bench top and animal models. CO2 insufflation of the peritoneal cavity was delivered up the target 20 mm Hg and maintained for 30 minutes from 1 or 2 cartridges in the swine model. No intraoperative incidents were registered, and all the recorded physiological parameters were within normal limits. The PAID prototype is a feasible, easy to use device that provides quick, controlled, and safe insufflation of the peritoneal cavity. Future studies will focus on testing the next-generation, semiautomatic PAID prototype in a severe intraabdominal injury model.

RESUMO

Diffuse large B-cell lymphoma (DLBCL) is the most common type of aggressive lymphoma, being part of mature B-cell neoplasm according to the 2016 World Health Organization (WHO) Classification of lymphoid tumors. This type of non-Hodgkin's lymphoma (NHL) can develop in the lymph nodes in most cases, or in extranodal sites (the most frequent involvement being the digestive tract, but also the thyroid, central nervous system, testes, etc.). Despite being an aggressive lymphoma, DLBCL benefits of potentially curable therapy. The addition of monoclonal antibodies to standard chemotherapy in the therapeutic approach of DLBCL leads to some net superior results to those obtained by chemotherapy alone. Despite the fact that the aggressive therapy is very efficient, 10% of patients remain refractory to it, 30-40% of them after obtaining a complete response (CR) will relapse, and 90% of refractory DLBCL have poor survival rates. Based on these findings, an explanation for the differences in clinical outcome and therapy response was attempted. The important progresses made in the understanding of DLBCL heterogeneity were based on molecular biology studies and showed differences in chromosomal alterations and in signaling pathways activation. These findings have paved the way for new therapeutic targets in order to improve therapy response. The large heterogeneity of DLBCL is acknowledged by the 2016 WHO Classification of lymphoid neoplasms, with 17 DLBCL subtypes, some of them as new varieties, compared to the 2008 Classification, and others introduced as provisional entities.

RESUMO

Epstein syndrome is an extremely rare genetic disorder characterized by the association of nephritis, deafness and megathrombocytopenia. We present the case of a 21-year-old patient diagnosed with Epstein syndrome and hyperparathyroidism secondary to chronic kidney disease. The main particularity of this case resides in the association between megathrombocytopenia and secondary hyperparathyroidism requiring surgery, which could lead to a series of concerns regarding the intra- and postoperative hemorrhagic risk of the procedure. Nevertheless, both the surgical procedure and the postoperative recovery were uneventful, suggesting that the lower threshold for preoperative thrombocyte count in megathrombocytopenia should be specifically considered on an individual case analysis.

RESUMO

BACKGROUND: Natural orifice transluminal endoscopic surgery (NOTES) emerged as a new alternative method in minimally invasive techniques. Although a very small number of studies have compared the physiologic response in NOTES to laparoscopy, the results remain controversial. AIM: This experimental animal study aims to evaluate the intraoperative cardiovascular and respiratory effects of pure transluminal natural orifice surgery and conventional laparoscopy. MATERIALS AND METHODS: Twenty female pigs (Sus scrofa domesticus) equally divided into two study groups were assigned to either pure natural orifice transluminal endoscopic techniques (Group 1) or conventional laparoscopic surgery (Group 2) and monitored intraoperatively in terms of heart rate (HR), systolic blood pressure (SBP) and O2saturation (SpO2) for 1 h. Both groups underwent simple surgical procedures such as gastrojejunostomy, oophorectomy and adnexectomy. RESULTS: All procedures were successfully completed. The findings indicated statistically significant differences between SBP (P = 0.0065) and SpO2(P = 0.027) in the two groups at the beginning of the interventions. HR showed significant differences during the last 20 min of the interventions (min 40 and 45; P < 0.001). For the whole procedure (from the beginning of the intervention to 60 min interval), HR, SBP and SpO2values showed no statistical difference. CONCLUSIONS: Although significant differences in terms of HR, mean blood pressure and SpO2were noted at specific intervals during surgery, no real variance of the cardiovascular parameters was observed when considering the entire procedure. Therefore, NOTES seems to be a safe approach with minimally intraoperative cardiovascular and respiratory implications.

RESUMO

Acute gastric remnant bleeding is an exceptionally rare complication when it occurs long after bariatric surgery. We present the case of a patient with a bleeding ulcer of the excluded stomach (i.e., the remnant), occurring 7 years after Roux-en-Y gastric bypass (RYGB) for morbid obesity. A computed tomography scan managed to locate the active bleeding source in the gastric remnant. During emergency laparotomy, a bleeding ulcer of the fundic region of the excluded stomach was identified. Total resection of the remnant was performed, with good post-operative recovery. To the best of our knowledge, this is the first full report of a significantly delayed haemorrhagic ulcer of the gastric remnant, occurring years after RYGB.

RESUMO

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of lymphoid malignancies, which counts for more than a third of non-Hodgkin's lymphoma cases. The aim of the current study is to evaluate the prognostic role of several immunohistochemical (IHC) markers involved in the pathological process of DLBCL. This is a retrospective analysis of the 97 de novo DLBCL patients admitted between January 2007 and December 2016 in the Department of Hematology, "Filantropia" Municipal Hospital, Craiova, Romania. The expression of Bcl-2, Ki67, c-MYC and p53 was assessed by immunohistochemistry. A significant level of association was observed between high prognostic index values and Bcl-2, Ki67, c-MYC and p53 positive cases. Moreover, overall survival and disease-free survival were higher in patients with negative expression for these markers. Bcl-2, Ki67, c-MYC and p53 could make important diagnostic and therapeutic targets; therefore, their routine assessment should be mandatory.

RESUMO

BACKGROUND: Obesity treatment options are of great interest worldwide with major developments in the past 20 years. From general surgery to natural orifice transluminal endoscopic surgery intervention nowadays, obesity surgical therapies have surely developed and are now offering a variety of possibilities. AREAS OF UNCERTAINTY: Although surgery is the only proven approach for weight loss, a joint decision between the physician and patient is required before proceeding to such a procedure. With a lot of options available, the treatment should be individualized because the benefits of surgical intervention must be weighed against the surgical risks. DATA SOURCES: Medline search to locate full-text articles and abstracts with obvious conclusions by using the keywords: obesity, surgical endoscopy, gastric bypass, bariatric surgery, and endoscopic surgery, alone and in various combinations. Additional relevant publications were also searched using the reference lists of the identified articles as a starting point. RESULTS: Laparoscopic Roux-en-Y gastric bypass still is the most effective, less invasive, bariatric surgical intervention, although there are various complications encountered, such as postoperative hemorrhage (1.9%-4.4%), internal hernias, anastomotic strictures (2.9%-23%), marginal ulcerations (1%-16%), fistulas (1.5%-6%), weight gain, and nutritional deficiencies. However, the absence of parietal incisions, less pain, decreased risk of infection, and short hospital stay make room for endoscopic surgery as a possible valid option for obesity for both the doctors' and the patients' perspective.
