Background: Small intestinal neuroendocrine tumors (SI-NETs) are the most common malignancies of the small bowel. Although typically well differentiated and slow-growing, they may exhibit aggressive behavior, especially when diagnosed at an advanced stage. Objective: To illustrate the diagnostic and therapeutic challenges of advanced SI-NETs through a rare case presentation and a narrative review of recent studies in the literature. Methods: A narrative literature review was conducted using the PubMed database to examine the incidence, risk factors, diagnostic modalities, and treatment strategies for advanced-stage SI-NETs. The search included studies published between January 2010 and June 2025 and focused on human subjects, using keywords such as “small intestinal neuroendocrine tumor”, “metastasis”, “tumor grade”, and “treatment”. Results: We report the case of a 68-year-old man who presented with bowel obstruction. Imaging and surgical exploration revealed a jejunoileal SI-NET with extensive liver and peritoneal metastases, mesenteric fibrosis, and ascites. Histopathology confirmed a well-differentiated grade 2 tumor (Ki-67: 3%) positive for chromogranin A and CD56. Despite a low proliferative index, the tumor demonstrated aggressive clinical behavior. The patient underwent emergency enterectomy with ileostomy and was referred for further evaluation, including somatostatin receptor imaging and consideration for peptide receptor radionuclide therapy (PRRT). Conclusions: This case highlights the potential for aggressive progression in well-differentiated SI-NETs with low Ki-67 indices. Histological grade alone may not predict clinical behavior. Early diagnosis, comprehensive staging, and individualized multidisciplinary management—guided by functional imaging and receptor profiling—are critical to improving outcomes in advanced SI-NETs.

Background: Non-variceal upper gastrointestinal bleeding (NVUGIB) remains a critical medical–surgical emergency associated with significant morbidity, mortality, and healthcare burden worldwide. Despite advances in diagnostic and therapeutic modalities, NVUGIB continues to pose complex clinical challenges, particularly in resource-limited settings. Methods: This retrospective observational study analyzed 364 consecutive adult patients diagnosed with NVUGIB and hospitalized at the First Surgical Clinic of the County Emergency Clinical Hospital Craiova between January 2009 and December 2014. Inclusion criteria required a confirmed diagnosis based on clinical presentation, laboratory findings, and upper gastrointestinal endoscopy (UGIE). Demographic variables, etiology, comorbidities, drug-induced triggers, laboratory parameters, onset-to-admission and onset-to-surgery intervals, endoscopic findings, therapeutic interventions (medical, endoscopic, surgical), rebleeding rates, and mortality were recorded and analyzed. Results were descriptively compared with historical data from the national and international literature. Due to the retrospective and aggregate nature of the data, survival analysis (Kaplan–Meier) was not applicable. Results: Peptic ulcers, erosive gastritis, Mallory–Weiss syndrome, and gastric neoplasms were the predominant etiologies. NSAID use, oral anticoagulation, and alcohol consumption emerged as major risk factors. Endoscopic hemostasis was achieved in the majority of cases; surgical intervention was required in 11.5% of patients, mainly for refractory or recurrent bleeding. The overall mortality rate was 10.9%, consistent with historical benchmarks. Comparative analysis revealed trends in etiology and management reflecting evolving clinical practice standards. Conclusions: NVUGIB remains a significant clinical challenge with persistent mortality and rebleeding risks. This cohort highlights the need for timely diagnosis, risk stratification, and an evidence-based therapeutic strategy integrating modern endoscopic and surgical options. An updated diagnostic and management algorithm is proposed to guide practical decision-making and optimize outcomes in similar tertiary care settings.

Background: Colorectal cancer (CRC) is a leading cause of cancer-related mortality worldwide, with Romania reporting among the highest rates in the European Union. Regional outcome data remain scarce. Methods: We performed a retrospective cohort study of 302 patients with surgically treated colorectal adenocarcinoma at a Romanian tertiary hospital between 2003 and 2005, with a median follow-up of 60 months. Survival was analyzed using Kaplan–Meier and Cox regression. Results: Radical resection with R0 margins was achieved in 72% of cases. The overall 5-year survival was 38%, with significantly lower outcomes in advanced stages. Independent predictors of poor prognosis included advanced stage, emergency surgery, incomplete resection, and older age. Conclusions: Survival outcomes in this Romanian cohort were substantially lower than those reported in Western Europe, reflecting the burden of late-stage presentation. These findings emphasize the urgent need for nationwide CRC screening programs and wider access to modern multimodal therapies.

Background/Objectives: Abdominal tumors can trigger acute, life-threatening complications, needing urgent care. Though often slow-growing, they may present suddenly with obstruction, bleeding, or organ compression. This article explores diagnostic challenges in such emergencies and presents a rare case of a giant mesenteric cyst. Methods: A PubMed search was conducted to review abdominal tumors in emergencies, focusing on mesenteric cysts. Results: A 37-year-old woman with no significant history presented with two weeks of diffuse abdominal pain and distension. Labs showed mild inflammation and low malignancy risk. Imaging revealed a large cystic mass compressing abdominal organs. Surgery found a 35 × 15 cm cyst from the mesenteric root extending into the pelvis and behind the stomach. Conclusions: Mesenteric cysts are rare with vague symptoms, needing high suspicion for diagnosis. Imaging helps, but large cysts often require surgery. Complete removal prevents recurrence, and bowel resection may be needed if vital structures are involved. Careful planning, teamwork, and follow-up ensure success.

Background/Objectives: Ischemic colitis, typically caused by thrombosis or reduced blood flow in the inferior mesenteric artery, is the most common ischemic lesion at the colorectal level. This case contributes to existing knowledge by highlighting the rare co-occurrence of a thrombosed aortic aneurysm and ischemic colitis, pointing to a direct vascular etiology rather than a multifactorial or idiopathic cause. Methods: A thorough electronic search was conducted on PubMed to identify risk factors and etiological determinants of ischemic colitis. Results: We present the case of a 70-year-old male with diffuse abdominal pain and multiple cardiac comorbidities. A CT scan revealed aeroenteritis, aerocolia, fusiform aneurysmal dilation of the abdominal aorta (18 cm long, 7.3 cm in diameter, from below the renal arteries to the bifurcation), parietal thrombosis, a circulating lumen of 2.7 cm, and inferior mesenteric artery thrombosis. Intraoperatively, necrosis was found in the upper rectum, sigmoid colon, descending colon, and the middle third of the left transverse colon, with clear demarcation between healthy and necrotic tissue. A subtotal proctocolectomy with transverse colostomy was performed. Conclusions: This case highlights ischemic colitis as a vascular disorder, urging broader differential diagnosis when common causes are unclear. Timely imaging, a multidisciplinary approach, and attention to vascular risks are key to identifying rare causes like aneurysmal thrombosis. While thrombosed abdominal aortic aneurysms can cause mesenteric ischemia, their link to ischemic and ulcerative colitis is unique, emphasizing the importance of accurate risk assessment in treatment planning.

Background/Objectives: Anorectal and retroperitoneal abscesses, although differing in frequency and presentation, present significant diagnostic and therapeutic challenges, especially when interconnected through complex fascial planes. Rare cases such as horseshoe ischiorectal phlegmons with extraperitoneal spread are particularly difficult to manage due to limited literature and the absence of standardized protocols. This article presents a rare case alongside a narrative review of similar cases, aiming to highlight key diagnostic pitfalls and therapeutic strategies. Methods: We conducted a narrative literature review using PubMed, Embase, Scopus, and Web of Science to identify reports on horseshoe ischiorectal phlegmons with extraperitoneal or retroperitoneal extension. Relevant studies were compared with the present case. Results: We describe a 59-year-old male who presented with severe sepsis, diffuse abdominal pain, and hemodynamic instability. Imaging and surgery revealed extensive necrotizing spread to the anterior abdominal wall, peritoneum, and retroperitoneal space, despite absent local perianal signs. Emergency midline laparotomy, wide debridement, and drainage were performed. Despite intensive care, the patient suffered rapid clinical deterioration and died within six hours postoperatively. Conclusions: This case and literature review highlight how a clinically silent ischiorectal phlegmon can progress to extensive extraperitoneal involvement and fatal sepsis. This underscores the need for early recognition, advanced imaging, and aggressive multidisciplinary management. Further studies are needed to develop evidence-based guidelines for complex anorectal abscesses with deep fascial extension.
