RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
RESUMO
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.
