RESUMO
Carbohydrate antigen 19-9 (CA 19-9) is widely recognized as a tumor marker primarily associated with pancreatic cancer. However, its elevation in benign pancreaticobiliary conditions complicates its diagnostic utility. We present the case of a 39-year-old male with no significant medical history who presented with symptoms of abdominal pain, nausea, vomiting, and diarrhea. The initial diagnosis suggested viral enteritis, but the subsequent worsening of symptoms led to further investigation. Elevated white blood cell counts, bilirubin levels, and liver function tests prompted magnetic resonance cholangiopancreatography (MRCP), which revealed dilated bile ducts and acute cholecystitis. Following endoscopic retrograde cholangiopancreatography (ERCP), significant hemobilia was observed, raising suspicions of cholangiocarcinoma. Despite extensive investigations, including CT angiography, MRCP, and repeat ERCPs, no malignancy was detected. Remarkably, the CA 19-9 level was elevated to 904 U/mL after the initial ERCP and uptrended to 7380 U/mL. These levels, however, normalized to 13 U/mL within two weeks of discharge. While CA 19-9 is a valuable marker in the diagnosis of pancreatic cancer, its elevation in benign pancreaticobiliary conditions necessitates cautious interpretation. In our case, choledocolithasis, cholangitis, and biliary manipulation appeared to have contributed to a transiently elevated CA 19-9. Clinicians must consider the entire clinical context when evaluating elevated CA 19-9 levels to avoid misdiagnosis and ensure appropriate patient management.
RESUMO
Gastroduodenal intussusception (GDI) is a very rare clinical entity in adults. GDI can present acutely or chronically in adults with varying spectrum of symptoms and signs. GDI can present acutely with abdominal pain, vomiting and palpable mass. In rare instances it can lead to anemia and cachexia. Computed tomography (CT) of the abdomen can demonstrate GDI in majority of cases. However, endoscopy findings could lead to identifying etiological factor and tissue diagnosis. In majority of the cases endoscopy may show mucosal or submucosal lesion leading to GDI. We bring forward a case of GDI wherein patient presented with cachexia, intermittent vomiting along with anemia. Further workup including imaging has resulted in the rare diagnosis of GDI. Interestingly we encountered a rare of its kind, endoscopic presentation where there was total absence of stomach due to its complete invagination through the pylorus into the duodenum arising from a giant gastric hyperplastic polyp. We have successfully managed this patient with surgical intervention leading to positive clinical outcomes. On review of literature, we found that it is extremely rare to have a completely absent stomach on endoscopy in a patient with no previous surgical intervention. We would like to share our experience so that endoscopists are aware of such uncommon and interesting presentations. To the best of our knowledge, such a case has not been reported so far in literature.
RESUMO
Coronavirus disease 2019 (COVID-19) predominantly presents with respiratory symptoms, however, the involvement of the gastrointestinal system has also been reported. Isolated gastrointestinal manifestation due to COVID-19 presenting as colonic distension is uncommon. Colonic ileus from COVID-19 infection presents as dilatation on imaging, with the risk of subsequent ischemia and perforation if not recognized and treated promptly. There is no consensus on the treatment modality for COVID-19-related colitis, however, COVID-19-targeted medications in conjunction with surgical intervention have been performed for management. We present a case of a 73-year-old man who presented with abdominal pain, distention, and diarrhea. He tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and was found to have marked dilatation of the colon on imaging. He was initially given convalescent plasma to reduce inflammatory markers, as tocilizumab was contraindicated due to suspected bowel obstruction. Once more stable, he underwent surgical intervention followed by tocilizumab infusion. Pathological specimens of the colon demonstrated hemorrhagic colitis with microthrombi suggestive of COVID-19-related colitis. Recognizing COVID-19-related colitis allows for timely diagnosis and management with targeted interventions in addition to surgery, which may prevent perforation. We suggest convalescent plasma followed by the formation of colostomy and finally infusion of tocilizumab as a feasible option for the treatment of COVID-19-related colitis. However, further research is needed in order to fully understand this entity and provide guidance for its management.
RESUMO
PURPOSE: Clostridioides difficile infection (CDI) is one of the most common health care-associated infections in the United States. Studies revealed a higher mortality when CDI is associated with liver cirrhosis. We aim to present the outcomes of CDI among patients with and without liver cirrhosis and to analyze the association of Model for End-Stage Liver Disease (MELD) and Child-Pugh (CPT) scoring with the severity of CDI. METHODS: A retrospective observational study was conducted in hospitalized patients with CDI diagnosed via a 2-step method - glutamate dehydrogenase (GDH) and toxin polymerase chain reaction (PCR). Patients with liver cirrhosis were identified based on ICD codes and chart review. MELD and CPT scores were calculated using laboratory parameters at the time of hospitalization. We compared CDI-related mortality in patients with and without cirrhosis and reviewed the CDI severity distribution in cirrhosis patients. RESULTS: A total of 526 patients were included in the study, of which 478 (90.87%) were non-cirrhotic and 48 (9.13%) were cirrhotic patients. Mortality rate was higher in cirrhosis group compared to the non-cirrhosis group (39.6% vs. 14.6%,P = 0.001). Among cirrhosis patients, those who survived had lower MELD score compared to the expired group (14.9 vs. 18.58, P = 0.106). There was no correlation of mortality based on CPT score in the cirrhosis group (P = 0.062). In post hoc analysis comparing the severity of CDI to liver cirrhosis, cirrhosis patients are more likely to present with severe-complicated disease. Multivariate logistic regression identified liver cirrhosis, severe-complicated CDI and serum albumin level as independent predictors of mortality. CONCLUSION: Our study noted a more severe disease presentation and higher mortality in patients with cirrhosis admitted with CDI. Further studies are required for better understanding of the clinical course of CDI in cirrhosis and to evaluate the need for early intervention in this patient group.
RESUMO
PURPOSE: Mouse model experiments have demonstrated an increased Clostridium difficile infection (CDI) severity with Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) use. We aim to evaluate the impact of NSAIDs in humans after a diagnosis of CDI on primary outcomes defined as I) all-cause mortality and II) toxic mega-colon attributable to CDI. PATIENTS AND METHODS: All hospitalized patients with a diagnosis of CDI were divided into two groups; those with NSAIDs administered up to 10 days after onset of CDI versus no NSAIDs use. The primary outcomes were analyzed between the groups, while controlling for severity of CDI. A logistic regression analysis was performed to identify the predictors of worse outcomes. RESULTS: NSAIDs were administered in 14% (n=80) of the 568 hospitalized visits for an average of 2.5 days after the CDI diagnosis. All-cause mortality was high in patients who did not receive NSAIDs as compared to those who did receive NSAIDs (16.6% vs 12.5%, p 0.354). Patients who were prescribed NSAIDs were more likely to have toxic mega-colon as compared to those who were not prescribed NSAIDs (2.5% vs 0.6%, p 0.094). Results were not statistically significant, even after controlling for CDI severity. Logistic regression analysis did not identify NSAIDs administration as a significant factor for all-cause mortality in CDI patients. CONCLUSION: This retrospective study results, contrary to mouse model, did not show association between NSAID use and CDI related mortality and toxic mega-colon. Shorter duration of NSAIDs use, younger people in study group, and timely CDI treatment may have resulted in contrasting results.
RESUMO
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS) is known as an unclassified group of non-Hodgkin lymphomas. PTCL-NOS is a subtype of peripheral T-cell lymphoma that accounts for 3% of all lymphomas in the United States. PTCL-NOS commonly presents as a disseminated disease, B symptoms (fever, night sweats, and weight loss), generalized lymphadenopathy, bone marrow infiltration, and extranodal involvement. Other rare and possible manifestations include peripheral eosinophilia, pruritus, or hemophagocytic syndrome. This type of lymphoma is aggressive in nature and carries a high mortality rate. There is no established standard-of-care treatment protocol for PTCL-NOS, several chemotherapy drug combinations are frequently used as a frontline treatment with an overall 5-year survival rate of 25%. We present a case of a 35-year old Hispanic woman who initially presented with a chief complaint of bilateral lower extremity swelling due to hypoalbuminemia and new-onset hyperkeratotic skin of the palms and soles.
RESUMO
Adenocarcinoma of the lung infrequently metastasizes to the gastrointestinal tract. We report a rare case of a 65-year-old male with no respiratory symptoms diagnosed with adenocarcinoma of the lung by histopathological examination of metastatic sites which included an ulcer in the gastric body and a mass in the rectum. Metastatic disease also involved the liver as well. Patient was treated with systemic chemotherapy but unfortunately expired five months after the diagnosis was made.
RESUMO
Cystic lymphangiomas are benign colonic neoplasms arising from the submucosa. Traditionally, endoscopic resection has been described for smaller lesions, while surgery is reserved for larger symptomatic lesions. We present a case of a 69-year-old asymptomatic individual noted to have a cystic lymphangioma of the colon measuring 5 cm, which was successfully removed with endoloop endoscopic resection without any complications.
RESUMO
Endometriosis is a common gynecological condition wherein there is an ectopic implantation of the uterine endometrial tissue. While several diagnostic modalities are described for the condition, laparoscopy remains the gold standard. There is still an undiscovered area to diagnose colonic endometriosis at an earlier stage. We present a case report of a reproductive age woman with cyclical rectal bleeding diagnosed with colonic endometriosis with colonoscopy and biopsy using saline injection lift and sampling technique. We in our report try to impress the fact that this differential should always be considered in the appropriate clinical setting, especially in women of childbearing age and in such cases, deeper tissue sampling techniques should be sought for, given better diagnostic yield. This may be clinically important given that it may aid in earlier diagnosis and thereby early initiation of appropriate therapy before the disease takes a complicated route. It may also be helpful in avoiding unnecessary surgery, along with the morbidity, complications and costs associated with same.
RESUMO
Hepatocellular carcinoma (HCC) is the most common primary malignancy of liver. Distant metastasis to various organs is well known. Skeletal metastasis is also reported to various locations. Vertebral metastasis has been reported mostly to thoracic spine. However, cervical spinal cord involvement leading to cord compression has been reported very rarely in literature. We present a case of 58-year-old male with liver cirrhosis presenting as neck pain. Further work-up revealed metastatic HCC to cervical spinal cord resulting in acute cord compression. Patient has been treated with neurosurgical intervention.
RESUMO
BACKGROUND: Diabetic ketoacidosis (DKA) is a common acute complication of diabetes mellitus requiring aggressive medical management. We attempted to study the incidence and various clinical and laboratory variables associated with acute gastrointestinal bleeding (AGIB) and acute upper AGIB (AUGIB) in patients with DKA. METHODS: We conducted a retrospective chart review of all the patients admitted to our hospital with DKA between January 2010 and December 2015. We collected demographic, clinical, laboratory, endoscopy and hospitalization details using an electronic medical-record database. Patients were divided into two groups based on the occurrence of gastrointestinal bleeding. RESULTS: A total of 234 patients with DKA were admitted during this period, of which 27 (11.5%) patients had documented AGIB. The majority of patients had hematemesis (n=22, 9.4%) except two had rectal and three had occult bleeding. We did not notice any difference in age, gender and ethnicity distribution between the two groups. There was no difference in the serum levels of electrolytes, anion gap, pH and hemoglobin A1C between the two groups. However, patients with AGIB had significantly higher initial blood glucose levels (738 vs 613 mg/dL, p =0.014). There was also increased mortality (7.4% vs 4.8%) in patients with AGIB, but this did not reach statistical significance. CONCLUSION: We conclude that higher initial serum blood glucose was associated with increased incidence of AGIB in patients admitted with DKA. We also noted increased in-patient mortality in patients with DKA who had AGIB, even though statistically insignificant. More aggressive measures to correct blood glucose levels may result in decreased incidence of AGIB, thereby reducing mortality during hospitalization in patients with DKA.
RESUMO
Gastrointestinal leiomyomas are smooth muscle tumors arising from the muscularis mucosae, muscularis propriae and possibly from smooth muscle of the vessel wall. Management depends on the size, location and the clinical scenario. Endoscopic snare cauterization with or without saline lift has been described in literature for tumors involving the left colon. To the best of our knowledge, endoscopic resection of right colon leiomyoma was never attempted in the past. We present a case of cecal leiomyoma which was resected endoscopically.
RESUMO
Ectopic adrenocorticotropic hormone secretion is responsible for 12% to 17% of all cases of the Cushing syndrome. One of the most commonly described causes of ectopic adrenocorticotropic hormone secretion is small cell carcinoma of the lung. A rare cause includes a functioning neuroendocrine tumor traditionally known as carcinoids that account for 5% of all mediastinal tumors. To our knowledge, all reported cases of mediastinal carcinoids are thymic in origin and only a minority of those is functional. We present a male patient with hypertension, obstructive sleep apnea, and acid-base disorder, in whom further investigation revealed an anterior mediastinal mass and Cushing syndrome.

Primary hepatic leiomyosarcoma is exceedingly rare accounting for less than 1% of the hepatic tumors. Close to 45 cases have been reported in the English literature. Presentation is usually nonspecific and diagnosis is often delayed until tumors reach a large size. This leads to a dismal prognosis. The tumors are not yet fully understood, hence the standard of care is not well defined. Curative resection remains the mainstay of management. Close association of Epstein Barr virus (EBV) induced soft tissue sarcomas is proven, especially in the presence of immunosuppression encountered in HIV/AIDS patients and in posttransplant patients. We herein present a case report of a 54-year-old man diagnosed to have HIV/AIDS and EBV infection admitted to our hospital with complaints of intractable hiccups for more than a week. Extensive workup revealed primary leiomyosarcoma of the liver.
RESUMO
We report this case of secondary amyloidosis associated with Castleman's disease. A 51-year-old man presented with systemic symptoms of generalized weakness, fatigue, unintended weight loss, anorexia and progressively worsening abdominal distension. On examination he was found to have an indurated right-sided submandibular mass and tense ascites. He was found to have multiorgan dysfunction with deranged liver function tests and renal failure. Ascitic fluid analysis revealed evidence of spontaneous bacterial peritonitis. Biopsy of the submandibular mass revealed angiofollicular lymph node hyperplasia consistent with a diagnosis of Castleman's disease. A subsequent liver biopsy showed extensive deposition of amyloid protein. Bone marrow biopsy also showed the presence of amyloid and increased kappa light chain-restricted plasma cells. The patient was not considered a candidate for chemotherapy or solid organ transplantation in view of active sepsis and poor physical condition. Secondary systemic amyloidosis complicating Castleman's disease is very rare. Untreated secondary systemic amyloidosis often has a rapidly fatal course, such as seen in our patient.
