AI Article Synopsis
- The study used a dacryoendoscope to investigate the internal orifice of congenital lacrimal fistulas in 5 patients.
- A suture was successfully tracked from the skin opening into the lacrimal drainage system, reaching the lacrimal sac in all cases.
- Findings indicate a greater likelihood of congenital lacrimal fistulas being connected to the lacrimal sac than previously thought, highlighting limitations in earlier identification methods.
Article Abstract
We examined the location of the internal orifice of congenital lacrimal fistula using a dacryoendoscope in 5 patients. A suture inserted from the skin orifice and passing into the lacrimal drainage system through the fistula track was identified using a dacryoendoscope. Consequently, the suture passed into the lacrimal sac in all patients. Although the internal orifice had been reported to be predominantly located in the common canaliculus, the methods previously used for identification of the internal orifice were less accurate. The results in our study suggest a higher incidence of congenital lacrimal fistulae connected with the lacrimal sac.

Background: In patients with moderate and severe secondary tricuspid regurgitation (STR), the effective regurgitant orifice area (EROA), corrected using the proximal isovelocity surface area (PISA) method for tricuspid valve leaflet tethering and low TR jet velocities, has an unclear threshold for identifying high-risk patients. This study aimed to establish a risk-based EROA cutoff and assess the impact of right ventricular (RV) remodeling on outcomes in low-risk STR patients according to EROA.
Methods: We included 513 consecutive outpatients (age 75±13 years, 47% male) with moderate and severe STR.

A 54-year-old male underwent a low anterior resection in 2015 for rectal adenocarcinoma. He presented to the emergency department with a two-week history of fever, perianal pain, an erythematous, warm, and actively draining mass. Physical examination revealed a perianal abscess in the left posterior gluteal region, with a palpable internal fistulous orifice 3 cm from the anal margin.

The flow convergence method includes calculation of the proximal isovelocity surface area (PISA) and is widely used to classify mitral regurgitation (MR) with echocardiography. It constitutes a primary decision factor for determination of treatment and should therefore be a robust quantification method. However, it is known for its tendency to underestimate MR and its dependence on user expertise.
