Colorectal cancer (CRC) is a leading cause of cancer-related morbidity and mortality, influenced by both genetic and epigenetic factors. Long non-coding RNAs (lncRNAs) such as GAS5 and CASC8 have been implicated in cancer susceptibility. This study aimed to assess the association of GAS5 rs145204276 ins/del and CASC8 rs10505477 A>G polymorphisms with CRC risk in a Romanian population. A case-control study was conducted, including 156 CRC patients and 195 healthy controls. Genotyping for GAS5 and CASC8 polymorphisms was performed using real-time PCR, and the association with CRC risk was evaluated using logistic regression to calculate odds ratios (OR) and 95% confidence intervals (CI). The carriers of GAS5 rs145204276 del allele was significantly associated with increased CRC risk (OR: 2.13, 95% CI: 1.24-3.63, p = 0.005) in a dominant model. In the subgroup analysis, the association of GAS5 rs145204276 ins/del polymorphism was restricted to distal colon cancer cases (OR: 2.98, 95% CI: 1.57-5.66, p = 0.001), advanced tumor stages (III + IV) (OR: 2.54, 95% CI: 1.31-4.91, p = 0.007), and poorly differentiated tumors (G3) (OR: 3.98, 95% CI: 1.49-10.59, p = 0.009). No significant correlation was found for the CASC8 rs10505477 A>G polymorphism. GAS5 rs145204276 polymorphism may influence CRC susceptibility, particularly in distal tumors and advanced stages. However, CASC8 rs10505477 polymorphism showed no association with CRC risk in this Romanian cohort.

Background: Variceal upper gastrointestinal bleeding (VUGIB) remains a major cause of short-term mortality in cirrhosis despite advances in endoscopic and pharmacological therapy. Prognostic factors and outcomes were evaluated in a historical cohort, and a guideline-aligned management algorithm is proposed. Methods: We conducted a retrospective study of 98 consecutive adults admitted with VUGIB to a tertiary surgical center in Romania (2009–2014). Demographics, etiology, admission hemoglobin (Hb), timing of presentation, endoscopic and surgical management, and outcomes were recorded. Survival was analyzed using Kaplan–Meier with log-rank tests; associations were tested with chi-square and t-tests; predictors of mortality were assessed with logistic regression. Receiver operating characteristic (ROC) curve analysis was used to evaluate the discriminatory ability of hemoglobin for in-hospital mortality. Results: Mean age was 57.8 ± 11.7 years; 60.2% were male. Cirrhosis etiology was alcoholic in 73%, viral in 18%, and metabolic in 9%. Endoscopy occurred within 48 h in 62% of patients, but only 4% underwent the procedure within 8 h. Overall mortality was 17.3%. Kaplan–Meier analysis showed no survival difference between alcoholic and viral cirrhosis (log-rank p = 0.39), but survival was markedly lower with Hb < 8 g/dL (p < 0.001). Admission delay was prognostic: >24 h was associated with worse survival (p < 0.05). On multivariable analysis (reference 1–2 days), admission at 3–4 days (OR 35.3, 95% CI 1.6–786, p = 0.024), >4 days (OR 71.0, 95% CI 2.16–2337, p = 0.017), and <6 h (OR 22.4, 95% CI 1.25–399.7, p = 0.035) independently predicted death. Admission Hb predicted mortality with an AUC of 0.79; the optimal cut-off was 4.3 g/dL (sensitivity 57%, specificity 95%). Limited use of pre-emptive TIPS likely contributed to outcomes. Conclusions: In this historical cohort, mortality from VUGIB was driven mainly by bleeding severity and admission delay, rather than by cirrhosis etiology. The study provides a historical benchmark for Eastern Europe, highlights gaps in adherence to contemporary standards, and supports restrictive transfusion, early vasoactive therapy, antibiotics, urgent endoscopy, and pre-emptive TIPS. The retrospective single-center design and limited therapies available during the study period remain important limitations.

Introduction: surgery for rectal cancer often presents multiple tactical and technical challenges due to factors such as the tumor's extent, limited anatomical space, proximity to the anal sphincter complex, and the use of neoadjuvant radiotherapy. These factors can significantly increase the complexity of surgery and the risk of both immediate and delayed complications, which can occur intraoperatively or postoperatively. Objective: the aim of this study was to retrospectively analyze the causes, diagnostic methods, and management of complications in patients who underwent surgery for rectal cancer. Additionally, the study sought to evaluate the impact of these complications on patients' therapeutic outcomes. Materials and Methods: we conducted a single-center, non-experimental, descriptive retrospective study over a five-year period at a single surgical clinic. The cohort consisted of 157 patients with rectal cancer, with various tumor locations, who underwent either radical or palliative surgical interventions. We analyzed demographic data, clinical and imaging factors, and statistically assessed intraoperative incidents, accidents, and postoperative complications. Results: complications were not isolated events; many patients experienced multiple associated complications. The overall complication rate was 16.56%, with 15.38% of complications being hemorrhagic incidents, 7.69% involving vascular or nervous plexus injuries, and 13 patients experiencing anastomotic dehiscence. Additionally, 26.9% of patients had complications related to the stoma, and 15.38% developed anastomotic stenosis. The overall mortality rate was 3.82%. Conclusions: surgeons performing rectal cancer surgeries must undergo extensive training to ensure accurate early diagnosis, effective surgical technique, and the proper management of postoperative complications. This approach is crucial in preventing negative outcomes, including diminished quality of life for patients and higher mortality rates.

Introduction: Small bowel cancer is very rare; although the incidence of adenocarcinoma and other anatomopathological forms has increased recently, the diagnosis and treatment of this disease are still debatable because of the clinical heterogeneity and the absence of studies including a large number of patients. Materials and Methods: We performed a retrospective study over 10 years in which we analyzed the clinical, imaging, and anatomopathological data of 46 patients hospitalized in a surgery clinic and diagnosed with small bowel cancer (duodenum, jejunum, and ileum). Results: After clinical assessment of these patients, including complications (occlusion, bleeding, and perforation), the CT scan established the diagnosis in over 90% of the cases of the complicated form of the disease. Surgery has a curative role in localized cancers; tumor location, local invasion, the presence of locoregional lymph nodes, and the number of multiple tumors influence the type of surgery. The conventional pathological exam was completed via immunohistochemical staining. Adjuvant oncological treatment was performed after surgery (according to the guidelines); in patients with exceptional histopathological forms, the therapy was personalized. Conclusions: Most small bowel cancers were diagnosed with complications (occlusion and bleeding); the tumor type, location, and presence of multiple bowel cancers significantly influenced its management. Independently of the surgical resection (R0/R1 or R2), the prognosis of the disease depends on the tumor aggressivity, location (single/multiple), and locoregional node invasion.

Objectives. Esophageal cancer is one of the most aggressive types of cancer, with a 5-year relative survival rate of only 18%-20.5%. Survival is highly dependent on accurate positive diagnosis and staging, in which the imaging modalities available have a primary role. The study is focused on the analysis of the preoperative T and M staging strategy and the reliability of computed tomography and endoscopic esophageal ultrasound in predicting resectability. A second objective was to evaluate the influence of preoperative imaging modalities on decreasing the number of unnecessary thoracotomies and laparotomies. Material and Methods. This study was conducted on a lot of 97 consecutive esophageal cancers, admitted in the Second General Surgery to December 2019. We recorded patient data, imaging details and staging, as well as intraoperative aspects and tactics. For statistical analysis we have used chi square test. Conclusions. Computed tomography is not a basic investigation in the T-category evaluation of the TNM stage, the accuracy of the method being extremely variable with the T-stage, the type of CT scan. The maximum utility of CT remains in the identification of invasion of neighboring organs and the operability of the case. Despite the differences in the accuracy, sensitivity and specificity of computed tomography and endoscopic ultrasound in esophageal cancer, the use of these imaging methods is essential in staging esophageal cancer and establishing the therapeutic indication.

OBJECTIVES:The aim of the study was to assess the diagnosis and evolution of low anterior rectal resection syndrome (LARS) in patients admitted to a tertiary surgical center in Romania. MATERIALS AND METHODS:From 120 patients initially included in the analysis, after applying the exclusion criteria, we selected 102 patients diagnosed and operated on for neoplasm of the upper, middle, and lower rectum for which resection and excision (partial or total) of mesorectum was associated. All the patients we treated in the general surgery department of the County Emergency Hospital of Craiova within a time frame of 5 years (1 October 2017-1 September 2022), and all experienced at least one symptom associated with LARS. The group included 68 men and 34 women aged between 35 and 88, who were followed-up for at least 2 years. Patients with progression of neoplastic disease, with advanced neurological disease, and those who died less than 2 years after surgery were excluded. RESULTS:The overall incidence varied by gender, site of the tumor (requiring a certain type of surgery), and anastomotic complications, and it was directly proportional to the time interval between resection and restoration of continuity of digestion. CONCLUSIONS:Obesity, size of the remaining rectum, total excision of the mesorectum, anastomotic complications, and prolonged ileostomy time are cofactors in the etiology of LARS. The LARS score decreased in most patients during the 2-year follow-up, although there were a small number of patients in whom the decrease was insignificant. The persistence of major LARS at 6 months after surgery may predict the need for a definitive colostomy.

Objectives. The objectives of this study are to highlight the diagnostic and therapeutic difficulties in patients with complicated acute colonic diverticulosis. Methods. The study group comprised 40 patients hospitalized to the Second Surgical Clinic of the Emergency County Hospital in Craiova, Romania, through the emergency service between 2015 and 2021. Regarding the sex distribution of the patients with colonic diverticular disease studied, there was a predominance of males. The distribution of patients was as follows: 22 patients with acute colonic diverticulitis, out of whom 21 patients suffered from left acute colonic diverticulitis and 1 patient suffered from right acute colonic diverticulitis. Results. The diagnosis of acute colonic diverticulitis was made by corroborating the data obtained on the objective clinical examination with the data obtained by exploring the abdomen by means of computed tomography, which revealed a thickening of the colon wall (acute sigmoid diverticulitis predominated). The treatment applied to patients with acute diverticulitis was conservative and in patients with acute perforated colonic diverticulitis, the treatment of choice was the surgical one. Mortality was 7.5% of all the cases. Conclusions. In patients with perforated colonic diverticular disease, the administered treatment consisted in Hartmann segmental colectomy, wound care, peritoneal drainage. The reintegration of the colon in the digestive transit was performed after 3-6 months.

The majority of studies concerning Helicobacter pylori (H. pylori) are oriented towards the implication of infection with H. pylori in processes that end in the formation of neoplasia, without assessing the impact of the bacterium in triggering acute gastroduodenal hemorrhagic episodes. The present study includes 166 patients with upper digestive hemorrhage, admitted to the ATI Clinic, the Gastroenterology Clinic or to the Surgery II Clinic of the County Emergency Clinical Hospital in Craiova, Romania between 2017 and 2019. All patients were monitored for evolution and received treatment according to current guidelines, and hemorrhagic lesions were biopsied. In the study group, 56.8% of the patients with upper gastrointestinal bleeding (UGIB) were positive for H. pylori and 43.2% were negative. In patients less than 50 years of age, non-steroidal anti-inflammatory drug (NSAID) use and H. pylori infection had a cumulative effect in causing bleeding lesions, but in patients older than 50 years of age, the use of NSAIDs was replaced by therapies with oral antiplatelet or anticoagulant agents. The need for hemostasis surgery was more common in patients who exhibited H. pylori-positive UGIB compared to H. pylori-negative (16 vs. 9.7%). In patients with H. pylori-positive hemorrhagic lesions, gastric resection was frequently required to obtain hemostasis. Persistence of H. pylori infection in patients with a history of gastric resection (4.1%) still predisposes to a hemorrhagic or neoplastic complication.

Keratoacanthoma (KA) is an epithelial tumor of the skin, classically considered as having a malignant transformation risk of 15%; however, many authors and the new World Health Organization (WHO) Classification of skin tumors consider KA as an incipient variant of the cutaneous squamous cell carcinoma (SCC). The aims of the study were to assess the clinical, histopathological (HP) and immunohistochemical (IHC) aspects of the KA and the role of these factors in malignancy occurrence. The studied group comprises 194 patients diagnosed with KA or malignant KA, hospitalized in the Clinic of Dermatology, Emergency County Hospital, Craiova, Romania, between 2006 and 2019. There were 83 males and 111 females, aged 34 to 90 years, 57.21% of the patients being from the rural environment. The histopathology diagnosed 51 KAs and 143 malignant KAs (SCCs). Clinical diagnosis had a limited value in detecting the absence or presence of malignancy in the KA lesion, due to a low accuracy (36.08% and 29.89%, respectively) and specificity (23.07% and 27.02%, respectively); therefore, the HP exam of the surgical excision specimen has a paramount importance in establishing the diagnosis. IHC analysis revealed that the immunostainings for apoptosis-associated proteins and keratinocyte proliferative activity [p53, B-cell lymphoma-2 (Bcl-2), Ki-67 and proliferating cell nuclear antigen (PCNA)] provide some arguments to differentiate between KA and SCC in the studied cases. The correlation of clinical, HP and IHC data lead to an accurate diagnosis of KA; moreover, the clinical, HP and IHC data sustain the idea that KA is a particular form of well-differentiated SCC, which require an active therapeutic attitude.

It is well recognized that the inflammatory bowel disease (IBD) is associated with an increased risk of colorectal cancer (CRC). More susceptibility IBD genes have been reported, NOD2 being one of the most extensively investigated. The aim of this study was to evaluate a possible correlation between NOD2 rs2066844 C>T (also known as Arg702Trp or R702W) variant and CRC risk in a Romanian population. A total of 373 Romanian subjects (108 patients diagnosed with sporadic CRC and 265 controls) were enrolled in this hospital-based case-control study. The NOD2 R702W variants were detected by Real-time PCR using a predesigned TaqMan Genotyping Assay. The association between the genetic risk variant and CRC was expressed as odds ratios (OR) with 95% confidence intervals (CI). We did not find any statistically significant difference when we compared CC genotype with CT genotype (OR 1.1, 95% CI: 0.46-2.61; p=0.83) between CRC patients and controls. No TT homozygous genotype was detected. Also, we compared allele frequencies and no correlation was found (OR 1.09, 95% CI: 0.47-2.56; p=0.84). No association was found in the stratified analysis by tumor site, Dukes' stage and histological subtype. Our study suggests that the NOD2 R702W variant is not associated with CRC risk in the Romanian population. Further data from different and larger populations is required to determine whether NOD R702W SNP has effects on susceptibility to CRC.

This paper presents a very rarely encountered case of a 45-year-old female, admitted in our Surgical Clinic for upper digestive bleeding (repeated hematochezia). The upper endoscopy was negative, but the barium meal discovered an apparently extrinsic duodenal (D3) stenosis; abdominal ultrasound diagnosed a left liver mass suggesting a metastatic tumor. The hematochezia relapse, with hemodynamic instability imposed emergency surgery; on laparotomy, a bleeding tumor located on the duodenopancreatic region was discovered, and a pylorus-preserving pancreaticoduodenectomy (Traverso-Longmire) was performed. The histology and immunohistochemistry established the diagnosis of duodenal stromal tumor, CD34 and CD117 positive, with an estimated progression risk of 34%. The postoperative evolution was favorable, the patient being alive, four years after the surgery.

Vulvar cancer is a malignant disease having a low frequency and with well-established surgical and oncological treatments based on the stage of the disease. The most important therapeutic problem encountered is represented by cases of perineal local regional recurrence, which are common in patients with large primary tumors and can occur even if the margins of the resection had no tumoral invasion. We present a case study of a 64-year-old patient diagnosed one year ago with squamous vulvar carcinoma (G3) for which a vulvectomy was performed after neoadjuvant radiotherapy. The patient later developed local recurrence with invasion of the anal sphincter, creating a delicate problem regarding a surgical approach. The size and the extent of the recurrent tumor required a complex surgical intervention using a mixed surgical team of general surgeons and plastic surgeons. Surgical intervention with a large excision of the recurrent cancer along with amputation of the inferior rectum via perineal route, and creation of a left iliac anus was performed. The perineal defect was covered via a musculocutaneous flap using the gracilis muscle. The immediate post-operative evolution was favorable.

Colorectal cancer is the third most often encountered type of cancer and represents the third leading cause of cancer related deaths, on both sexes. One of the most important prognostic parameters is the tumor's stage at the time of the diagnosis. T4 cancers represent advanced tumors associated with penetration of the visceral peritoneum (T4a) and/or direct invasion in adjacent structures (T4b). Preoperative diagnosis is influenced by the inability of the existent imaging modalities to accurately differentiate the true invasion from the simple, inflammatory adherence to the neighboring structures. As a consequence surgical treatment must follow the principle of en bloc resection; however the ability of achieving an R0 resection depends on the tumor location, invaded organ, and the type of the surgical procedure required. Neoadjuvant treatment for advanced colon cancer it may be very difficult to be applied. This review is focused on preoperative workup, therapeutic strategies and subsequent results in advanced T4 colon cancers.

Colorectal cancer is the third most frequently reported malignancy and also the third leading cancer-related cause of death worldwide. Lymph node evaluation, both preoperatively and postoperatively, represents an important aspect of the diagnosis and therapeutic strategy in colorectal cancer, such that an accurate preoperative staging is required for a correct therapeutic strategy. Treatment of rectal cancer with positive lymph nodes, a very important predictive prognostic parameter, is currently based on neoadjuvant chemoradiotherapy followed by total/surgical mesorectal excision and adjuvant regimen. Preoperative evaluation of the lymph node status in rectal cancer is based on endoscopic ultrasound and magnetic resonance imaging, but their accuracy, specificity, and sensitivity still require improvement. Postoperative evaluation also presents points of debate, especially related to the role of sentinel lymph node mapping and their final implication, represented by detection of micrometastases and isolated tumor cells. The pathologic interpretation of tumor deposits represents other points in discussion. From a surgical perspective, extended lateral lymph node dissection vs. abstinence and (neo) adjuvant therapeutic approach represent another unresolved issue. This review presents the major controversies existing today in the treatment and pathologic interpretation of the lymph nodes in rectal cancer, the role/indication and value of the lateral pelvic lymph node dissection, and the postoperative interpretation of the value of the micrometastatic disease and tumor deposits.

Pancreatic head carcinomas are a rare cause of upper digestive bleeding and the diagnosis and the treatment of these pose particular problems. We selected 6 cases from a number of 283 patients who were hospitalized for surgery between January 2014 and December 2016 with signs of upper digestive bleeding with no varicose origin who were subsequently diagnosed with pancreatic head carcinomas. The diagnosis was established by endoscopic and surgical methods. The evolution of these patients was influenced by whether there was active digestive bleeding or history of digestive bleeding and the possibility of tumor resection. Four patients needed emergency surgery due to continuous bleeding or rebleeding. The resectability of the cephalo-pancreatic tumor was determined and then subsequently performed in two patients who had a favorable postoperative outcome, while in two patients the tumor resection was impossible. The other two patients with upper digestive haemorrhage responded favorable to drug therapy, and digestive endoscopy and CT explorations were negative. After a 5-month interval they presented with clinical signs of a pancreatic neoplasm with invasion into the common bile duct, unwanted weight loss, abdominal pain, and icterus of the sclera and skin. The surgical intervention resulted in the confirmation of locally advanced pancreatic head carcinomas and the performing of bilio-digestive derivations. Pancreatic head carcinomas may be associated with upper digestive tract haemorrhage due to duodenal or bile duct invasion. The clinical picture of these patients can vary from occult haemorrhage to severe upper digestive tract haemorrhage accompanied by hypovolemic shock.

Esophageal carcinoma represents a great diagnostic and therapeutic challenge due to the anatomical situation and physiopathology of the disease. The medical challenge can be even greater since esophageal carcinoma can evolve concomitant to another malignant tumor with different localization. This paper’s aim is to present a case of squamous esophageal cancer associated to another primitive malignant tumor-malignant pericolic conjunctive tumor, this kind of association being singular in medical literature from our knowledge. Upon emergency presentation the patient was sketching a sub-occlusive syndrome with mild anemia and inflammatory syndrome, somehow suggesting a possible right colon cancer. However, discreet upper digestive pole symptomatology that, on first sight, seemed secondary, made the consultant to perform a superior digestive endoscopy that raised a strong suspicion of early stage esophageal carcinoma. Further exploration was not completed because occlusive complication occurred and the patient needed emergency surgery. On laparotomy a stenotic right colic angle tumor was discovered that later proved to be extra-mucosal, with conjunctive origin. Our paper focuses on highlighting the crucial importance of the imagistic explorations in the primary diagnosis of esophageal carcinoma, in the correct staging (lymphatic extension, loco-regional or distant metastases) and also for malignant tumors with another localization that can radically modify the therapeutic strategy.

ABSTRACT: The early diagnosis of esophageal cancer is necessary for improving the surviving of patients with this disease. To ensure an accurate staging, there are necessary imaging tests to establish the local and regional extension, as well as excluding the metastases. Computed tomography (CT), endoscopic ultrasonography (EUS), and positron emission computed tomography (PET-CT) constitute standard methods for esophageal cancer staging. These techniques are complementary; using only one of these tests is not suitable for correct staging. The role of EUS has improved the doctors’ ability to evaluate and select the patients to undergo surgery, radiotherapy, or chemotherapy.

The pathogenesis of gastric cancer regardless of histological structure is a classic example of gene-environment interaction, and an important epidemiological aspect was the recognized association with Helicobacter pylori infection. This paper describes a case of gastric mucosa-associated lymphoid tissue (MALT) lymphoma in a young patient whose first sign of the disease was upper gastrointestinal bleeding and associated hemorrhagic shock. The patient is a 31-year-old man, diagnosed by endoscopy 10 years ago with H. pylori-positive chronic atrophic gastritis, who refused treatment to eradicate the bacterium and presents currently in the emergency room for serious upper gastrointestinal bleeding. Emergency upper gastrointestinal tract endoscopy highlights the presence of bleeding gastric tumors. It was a surgical emergency and intra-operatively the presence of invasive gastric cancer into the left hepatic lobe was noted which required total gastrectomy with the purpose of hemostasis. Immediate and remote postoperative evolution was favorable and post-operative follow-up at six months, 12 months, and 24 months showed no signs of local or distance occurrence.

Identification of sentinel lymph node (SLN) in colon cancer is very important in order to increase the accuracy of lymph node staging. The number of examined lymph nodes represents a significant predictor of survival. This study aims to show the importance of SLN histological and immunohistochemical examination in adjuvant oncological treatment. The study includes 23 patients with colon cancer (44% women and 56% men) who came in our clinic for surgical intervention. In all cases, the SLN was identified and prepared for histological examination. In 13 of the cases, micrometastases were found onhaematoxylin-eosin (HE) staining, there were 5 cases with positive immunohistochemistry using antibodies anti-p53, anti-VEGF-C, anti-CD34, and 5 cases with SLN negative both for HE and immunohistochemistry. Altogether we had a detection rate of 92%, an accuracy of 78,2%, a sensitivity of 90%, a false negative rate of 10% and a negative predictive value of 71,4%, good values according to the literature. Four (17,3%) patients had micrometastases exclusively in the sentinel lymph node, after performing additional histological examination, using multilevel section and immunohistochemistry. After assessing the SNL on our patients, we concluded that it is a reproducible practice for lymph node analysis.
