What is the appropriate diagnostic and treatment approach for a patient with worsening diffuse infiltrative disorders involving the duodenal jejunal loop and adnexal cysts?

From the Guidelines

The appropriate diagnostic and treatment approach for a patient with worsening diffuse infiltrative disorders involving the duodenal jejunal loop and adnexal cysts requires a comprehensive evaluation starting with advanced imaging, specifically contrast-enhanced CT or MRI of the abdomen and pelvis, as recommended by recent guidelines 1. This approach is crucial for characterizing the extent of the infiltrative process and the relationship between the intestinal and adnexal findings. The diagnostic workup should be followed by endoscopic evaluation with upper endoscopy and push enteroscopy to directly visualize the duodenal-jejunal mucosa and obtain tissue samples for histopathological examination, as suggested by the ECCO-ESGAR guideline for diagnostic assessment in IBD 1. Multiple biopsies should be taken from affected areas to increase diagnostic yield. Laboratory studies including complete blood count, comprehensive metabolic panel, inflammatory markers (ESR, CRP), CA-125, and CEA should be performed to assess the patient's overall condition and potential inflammatory or malignant processes. For the adnexal cysts, transvaginal ultrasound with Doppler flow studies is essential, potentially followed by MRI with contrast if malignancy is suspected, to accurately diagnose and manage these findings. Treatment depends on the specific diagnosis but may include surgical intervention for both the intestinal infiltrative process and adnexal cysts if malignancy is confirmed or strongly suspected. For inflammatory or infectious etiologies, targeted antimicrobial therapy or immunosuppressive medications like prednisone (starting at 40-60mg daily with gradual taper), azathioprine (2-3mg/kg/day), or biologics may be indicated, as outlined in the WSES-AAST guidelines for the management of inflammatory bowel disease in the emergency setting 1. This comprehensive approach is necessary because the dual presentation suggests either a systemic process affecting both sites or potentially related pathologies that require coordinated management by gastroenterology and gynecology specialists. Key considerations in the management of inflammatory bowel disease, as discussed in the guidelines 1, include the use of immunosuppressive therapies, biologics, and surgery, depending on the severity and extent of the disease, as well as patient preferences and comorbidities. The goal of treatment is to achieve induction of remission, followed by maintenance therapy to prevent recurrent disease flares and improve quality of life, as emphasized in the ECCO-ESGAR guideline 1.

From the Research

Diagnostic Approach

• The patient's worsening diffuse infiltrative disorders involving the duodenal jejunal loop require a comprehensive diagnostic approach, including further clinical workup, enteroscopy, and dedicated CT enterography to assess the bowel optimally 2.
• Imaging differentials for the patient's condition are wide and include the possibility of infectious disorders such as CMV or inflammatory spectrum disorders.
• The presence of adnexal cysts, which are inappropriate for the patient's age, can be further evaluated using ultrasound examination.

Treatment Approach

• If CMV infection is suspected, treatment with valganciclovir may be considered, as it has been shown to be effective in treating CMV infection and disease in immunocompromised patients 3, 4.
• Valganciclovir has been found to have advantages over ganciclovir, including a simpler and more convenient once-daily regimen, which can improve patient compliance 3.
• In cases of CMV-associated enteritis, oral valganciclovir has been found to be effective in treating the condition, especially when intravenous ganciclovir is not tolerated 4.

Differential Diagnoses

• The patient's symptoms and imaging findings can mimic other conditions, such as inflammatory, ischemic, and infectious colitides, and therefore, a thorough diagnostic workup is necessary to rule out other possibilities 5.
• The Diffuse Infiltrative Lymphocytosis Syndrome (DILS) is a rare multisystemic syndrome that can present with similar symptoms and should be considered in the differential diagnosis, especially in patients with HIV infection 6.
