Preliminary application of low-temperature plasma ablation combined with drug therapy in the treatment of infectious corneal ulcer / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To observe the preliminary therapeutic effect of low-temperature plasma ablation combined with drugs in the treatment of infectious corneal ulcer. <p>METHODS: Retrospective case study. A total of 30 eyes were selected from 30 patients with infectious corneal ulcer who were admitted to the ophthalmology department of the First Affiliated Hospital of Chongqing Medical University from December 2018 to March 2020. All patients had positive etiological examination and ulcer or infiltration depth ≤1/2 of corneal thickness. Local low-temperature plasma ablation combined with eye drops was applied to the cases whose corneal ulcer did not improve significantly or corneal infiltration continued to worsen after 3-7d of conventional anti-infection treatment. Postoperative follow-up was 3-6mo to observe the clinical effect.<p>RESULTS: After low-temperature plasma ablation combined with eye drops treatment, the infection in 12 eyes of 12 patients with bacterial corneal ulcer was controlled in 11 eyes of 11 patients and ulcer healed gradually. Keratoplasty was performed in 1 eye due to aggravated infiltration. Among 18 eyes of 18 cases with fungal corneal ulcer receiving low-temperature plasma ablation and combined local antifungal treatment, 13 eyes of 13 cases gradually healed; 2 eyes of 2 patients showed lichen-like changes after the first ablation, but the lesion area was significantly smaller than before and gradually improved after re-ablation treatment; there was no effect in 3 eyes of 3 cases and keratoplasty was finally performed. All the patients were followed up for 3-6mo, 26 eyes of 26 patients were cured and the infection had no recurrence with remaining corneal pannus or leukoplakia. Confocal microscopy did not detect mycelium in cured patients with fungal infection.<p>CONCLUSION: In this preliminary observation, low-temperature plasma ablation combined with drug therapy can effectively control infection, promote healing and improve visual acuity for infective corneal ulcer with infiltration less than 1/2 corneal thickness, and no obvious complications were observed.

Seguimiento endoscópico e histológico post ablación con argón plasma del esófago de Barrett extenso en pacientes sometidos a tratamiento quirúrgico previo / Argon plasma ablation of extensive Barrett esophagus: experience in 19 patients

Background: Endoscopic argon plasma ablation of Barrett esophagus decreases the risk of future esophageal cancer development. Aim: To assess the endoscopic regression of columnar epithelium and the presence of intestinal metaplasia among patients operated for Barrett esophagus and subjected to argon plasma ablation. Patients and Methods: In 19 patients with extensive Barrett esophagus subjected to a Nissen fundoplication, Barrett esophagus was endoscopically ablated with argon plasma. Patients were assessed 6 and 12 months after surgery to evaluate the regression of columnar epithelium and the presence of intestinal metaplasia. Results: One, two and three ablation sessions were carried out in 10, three and six patients, respectively. Three patients had complications. The initial length of columnar epithelium segment was 52 +/- 15.6 mm and decreased to 22.6 +/- 10.6 mm (p < 0.05). In 12 patients, there was absence of intestinal metaplasia on follow up, in six it persisted (one of them with "buried cells") and in one patient, dysplasia appeared. Conclusions: Endoscopic argon plasma ablation may have a complementary therapeutic role for the regression of columnar epithelium in Barrett esophagus.

Introducción: Pacientes con esófago de Barrett extenso presentan un riesgo de cáncer. De allí surge la posibilidad de someter a estos pacientes a ablación con argón plasma por vía endoscópica para disminuir este riesgo de desarrollar un adenocarcinoma. Objetivo: Evaluar la regresión endoscópica del epitelio columnar y la presencia de metaplasia intestinal en pacientes operados por esófago de Barrett y sometidos a ablación con argón plasma. Material y Método: Se incluyen 19 pacientes en este estudio, todos ellos con esófago de Barrett extenso confirmado por endoscopia e histología, los cuales se someten a ablación con argón plasma por vía endoscópica. Estos pacientes se controlaron con endoscopia e histológicamente a los 6 meses y al año de operados para evaluar la regresión del área con epitelio columnar y precisar la presencia histológica de metaplasia intestinal. Resultados: En 10 pacientes se efectuó 1 sesión de ablación, en 3 pacientes 2 sesiones y en 6 pacientes se efectuó 3 sesiones de ablación. Tres pacientes presentaron complicaciones. El largo de las lengüetas de epitelio columnar inicial fue de 52 +/- 15,6 mm el cual disminuyó a 22,6 +/- 10,6 mm (p < 0,05). El seguimiento histológico reveló ausencia de metaplasia intestinal en 12 pacientes (63,1 por ciento) persistencia de metaplasia en 6 pacientes (1 de ellos con células en submucosa, "buried cells") y un paciente con aparición de displasia. Conclusión: La ablación con argón plasma puede tener un rol en el tratamiento complementario a la cirugía para mejorar la regresión del epitelio columnar y disminuir los riesgos de presentar un adenocarcinoma de Barrett.
