Hidden Threat: Incidental Finding of Pancreatic Body Solid Pseudopapillary Tumor During Bariatric Evaluation With an Open Central Pancreatectomy Resolution.

Incidentalomas, or tumors found incidentally, are very common. However, pancreatic tumors are usually not found as incidentalomas. To date, these tumors represent a diagnostic and therapeutic challenge, since the risks and benefits associated with surgeries that can be performed to remove these tumors must be evaluated due to perioperative complications. It is vitally important to always carry out a correct approach that includes a histopathological study to allow timely identification of tumors that require surgical management or other preoperative treatment, such as chemotherapy or radiotherapy. The majority of these tumors are benign cystic tumors; however, there are cases, like the one presented here, where the tumor turns out to be a solid pseudopapillary tumor (SPT) that requires a different diagnostic and surgical approach. Also, in this case, the importance of evaluating the patient's general health status is highlighted to determine whether or not the required surgery can be performed at that moment or if any prior intervention is required. This case report talks about a patient in whom an incidental pancreatic tumor was found and how its management was carried out from diagnosis to the postoperative period.

Uncovering a Rare Case of Hepatic Round Ligament Epigastric Hernia.

Abdominal wall hernias are one of the most common surgical diseases present in both males and females nowadays. However, with only a few cases reported in the literature, hepatic round ligament hernias are a rare clinical manifestation. This case shows how a common symptom such as epigastric pain can be associated with this rare condition. In general, abdominal computed tomography (CT) images are the choice of study to evaluate complications and the involvement of different intestinal sections. Some laboratory tests can be performed to suspect intestinal ischemia secondary to strangulated hernias. Primary repair utilizing mesh is the preferred surgical treatment. This procedure can be performed through laparoscopic or open technique, depending on the surgeon's skills and patient preference.

Tackling the Unyielding Challenge of Necrotic Unresectable Hepatocellular Carcinoma: A Liver Necrosectomy Approach for Intratumoral Hemorrhage and Abscess Resolution.

Hepatocellular carcinoma (HCC) is one of the most common causes of gastrointestinal and hepatobiliary cancer worldwide. Chronic liver disease and cirrhosis persist as the most common risk factors, typically linked to instances of alcohol abuse or viral infections, notably hepatitis B and hepatitis C infection. Diagnosis can be made using patient history and image studies as there is no need for pathological confirmation. The only curative treatment is surgical resection, and in cases where the tumor is unresectable, as the one presented in this case, and when there are no contraindications, the only option is an orthotopic liver transplantation. This malignancy is not only associated with high mortality but also high morbidity associated with severe complications, such as hemorrhage, necrosis, and infection of the tumor. The significant relevance of this case lies in its capacity to illustrate that despite remaining in non-surgical management for months when an acute complication presented, it was timely identified and surgically treated. The emergence of complications, such as necrosis accompanied by abscess formation and intratumoral hemorrhage, represents an indication for prompt surgical management.

Pathological Thoracic Vertebral Fractures Secondary to Achromobacter denitrificans: A Case Report.

Vertebral fractures remain a diagnostic challenge nowadays. The first and most common diagnosis needed to be ruled out is osteoporosis. Other diagnoses to rule out involve pathological fractures. Pathological fractures are a group of pathologies that result in a spine fracture as part of an underlying disease process that affects the spine. This group includes Paget's disease, tumors, osteomyelitis, and vertebral compression fractures. Fractures secondary to vertebral osteomyelitis are presented as collapsed vertebral bodies secondary to bone destruction and the formation of lytic lesions. Clinical presentation includes severe back pain refractory to analgesic therapy, persistent unexplained fever, and leukocytosis without any other obvious focus of infection. In cases like the one presented here, early biopsy and culture should be performed on every patient that fits these criteria. However, as it presents unspecific symptoms most of the time, it is not suspected, and therefore it is associated with high morbidity and mortality.

Exploring Gastric Perforation as an Uncommon yet Critical Complication of Gastrointestinal Stromal Tumors.

Hollow viscus perforation poses a significant diagnostic and therapeutic dilemma for the majority of clinicians. It is vitally important that in cases of gastrointestinal perforation, the tissue that was perforated is always evaluated, since a malignant tumor can cause this complication as a presentation form. Here, we present the case of a patient whose first manifestation of a malignant gastric tumor was its perforation and the presence of septic shock secondary to this. This case exemplifies the importance of innovative thinking in facilitating a comprehensive diagnostic and therapeutic strategy, leading to the timely identification and management of a malignant tumor by the oncology team; such interventions not only enhance patient outcomes but also mitigate morbidity and mortality rates.

From Gut to Heart: A Case Report of Infectious Endocarditis Stemming From Cholecystitis-Induced Enterococcus faecium Bacteremia.

Systemic infections are not always going to present as we expect. The study of bacteremia and febrile syndrome represents one of the most important diagnostic challenges nowadays. This case demonstrates the importance of a multidisciplinary approach and finding a common point that explains all the patient's symptoms, no matter how disconnected they may seem. Here, we present the case of a patient where multiple treatments were performed to manage recurrent infective endocarditis due to Enterococcus faecium but the cause of this persistence was never found despite surgical management. With only a few cases reported in literature involving this pathogen, it is of great importance to emphasize how searching for a natural reservoir, such as the gallbladder, for this pathogen helped solve the diagnostic mystery that this patient represented. Here, we present how the culture of biological materials, such as the aortic valve replacement, as well as blood cultures, made it possible to identify the etiological agent associated with the pathology and, in turn, find the cause of recurrent bacteremia.

Ischemic Stroke as an Initial Manifestation of Antiphospholipid Syndrome in an Adolescent: A Case Report.

Cerebrovascular diseases in pediatric patients are relatively rare. Ischemic stroke in adolescents is associated with a poor prognosis. The most common causes include systemic diseases, such as heart disease and hypercoagulation disorders. It is important to mention that one of the most common acquired hypercoagulation states is the antiphospholipid syndrome (APS). Patients with this disease may present stroke as the first clinical manifestation, which not only increases morbidity in these patients but presents a diagnostic challenge. This case presents one example of how APS can present as a pediatric stroke. The diagnostic approach should always be through the presence of specific antibodies accompanied by the presence of a thromboembolic episode proven by catheterization or an imaging study. In the brain, the preferred imaging study is magnetic resonance imaging. Management is based on anticoagulation therapy and continuous monitoring in the intensive care unit.

Anaplastic Carcinoma Arising From a Mural Nodule in Benign Mucinous Cystadenoma.

Giant abdominopelvic tumors continue to present a diagnostic and therapeutic challenge for all surgeons despite all the advances in the world of imaging. Particularly, one of the most important challenges is to determine its probable origin for adequate surgical planning. Even though mostly all of these tumors are benign ovarian tumors, extraordinarily, malignant mural nodules may develop from the wall of these benign tumors, carrying an invariable unfavorable prognosis for the patient. This case highlights the importance of a correct diagnostic approach using ultrasound and abdominal computed tomography scans and confirming the diagnosis through a histopathologic examination. The treatment for these cases is surgical resection and posterior oncological treatment if needed. This case shows how timely treatment is one of the principal determinators of morbidity and mortality.

Reactive Arthritis as a Consequence of Infection by Clostridium difficile in a Pediatric Patient.

Reactive arthritis (RA) is the development of a sterile inflammatory arthritis usually associated with a previously known infection, most commonly from the gastrointestinal or urogenital tract. The diagnosis is clinical, based on the presence of acute oligoarticular arthritis of larger joints developing within two to four weeks of the infection. However, in some cases where the infection is not clear, the diagnosis is a challenge, like in the case presented here. We must always rule out past infections as a cause of arthritis by directly asking about the presence of symptomatology associated with it, presented in the past few weeks. It's important to emphasize that human leukocyte antigen B27 (HLA-B27) should not be used as a diagnostic tool, and it always needs to be correlated with the clinical features. There is no confirmed evidence in the literature that is in favor of prescribing antibiotic therapy during an acute presentation of RA as it usually presents after the infection is cured.

Guillain-Barré Syndrome in an Immunocompromised Patient: A Case Report.

Guillain-Barré syndrome (GBS) in post-transplant patients is a rare clinical presentation. Although in the literature this neurological condition has been mainly associated with viral infections secondary to immunosuppression, GBS should not only be suspected in patients with an acute condition. It is essential to always rule out a viral or bacterial cause, looking for the most common sources, i.e., urinary, respiratory, and gastrointestinal. The diagnosis of GBS is clinically based, and its management is based on the use of intravenous immunoglobulin (IVIG) or plasma exchange. Its timely diagnosis allows treatment to be started early, thus improving the prognosis of these patients and reducing the time of hospitalization and complications associated with it. This report shows how an interdisciplinary approach is vital in such cases, as both the precipitant and the disease must be managed to decrease the morbidity and mortality associated with this condition. It is crucial to evaluate the benefits and risks of withdrawing immunosuppressive treatment in post-transplant patients, and being able to recognize when restarting them is indicated.

Retroperitoneal Peripancreatic Ganglioneuroma Encasing the Celiac Trunk and Superior Mesenteric Artery.

A retroperitoneal ganglioneuroma is an exceptionally rare surgical entity, even more so in pancreaticoduodenal tumors. These well-differentiated neuroepithelial tumors originate in the neural crest, emerge in the sympathetic nervous system, and consist of ganglion cells and stromal Schwann cells. Generally, these tumors, despite being mostly benign, may be associated with venous or arterial vascular involvement. The symptomatology presented will depend on the mass effect due to tumor growth, and surgical excision is the only therapeutic option offered today to these patients. However, encapsulation of the main vessels represents a great surgical complexity. Various surgical approaches have been employed throughout history; however, the current preferred method is an open midline laparotomy, involving an extensive Kocher maneuver and an artery-first approach, aiming for an R0 resection of the tumor with total vascular preservation to the greatest extent possible. We present a case of an R2 resection involving a 95 mm x 85 mm retroperitoneal peripancreatic ganglioneuroma with double vascular involvement (celiac trunk and superior mesenteric artery). The procedure utilized an artery-first approach with total vascular preservation in a 17-year-old woman who had long-standing gastrointestinal symptoms due to the mass effect.

Complete Traumatic Rupture of the Pancreas by a Horse Saddle: A Case Report.

Pancreatic trauma is one of the least observed diagnoses in the emergency room, much less in pediatric emergencies. Any cause of direct abdominal blunt trauma can cause it. With only a few cases presented in the literature, horse accidents have been associated with this complication, but it has been never seen in literature as a case where the horse-riding saddle is the one causing the pancreatic trauma, until now. Emphasizing the importance of an early diagnosis is the key point, but more importantly, to highlight that the correct diagnostic approach will grant the opportunity for a lesion in the main pancreatic duct to be identified, which will allow a timely surgical approach, increasing overall survival rates and decreasing morbidity in these patients. Here lies the importance of not only utilizing a specific study, such as a computerized tomography (CT) scan to evaluate abdominal trauma but also using other image studies that are better suited for pediatric patients, such as magnetic resonance image (MRI) with cholangiopancreatography (MRCP).

Intussusception of Gastrojejunostomy After Pancreatoduodenectomy With Billroth II Reconstruction.

Gastrojejunal anastomosis or gastrojejunostomy (GJ) is a surgical procedure used for allowing gastric emptying, especially in cases where complex reconstructions are needed. One of the less common complications but one of the most relevant in morbidity is the intussusception of the GJ. It requires a high index of suspicion, preoperative optimization of the patient, diagnostic corroboration, and identification of associated complications with the use of contrasted imaging. It was described for the first time by Bozzi in 1914; currently, multiple cases have been described in the literature, being more frequent in bariatric surgeries and reconstructions after distal gastrectomy. In hepatopancreaticobiliary surgery, it is an even uncommon complication. We present the case of a 60-year-old man with intussusception of the efferent loop of the GJ after a pylorus-preserving pancreatoduodenectomy with a Billroth II reconstruction in the setting of malignancy of the extrahepatic bile duct along with our emergency surgical treatment.
