Place of plasma argon coagulation in the treatment of vascular abnormalities of the digestive tract in adults

The aim of our study is to evaluate the value of Argon Plasma Coagulation in the treatment of gastrointestinal vascular abnormalities. Patients and methods: This is a descriptive and analytical retrospective study, from January 2009 to September 2020. 198 patients who have benefited from treatment with Argon Plasma Coagulation for vascular anomalies of the digestive tract divided into 2 groups: -Group A: Patients with radial rectitis lesions (n = 107). -Group B: Patients with lesions of digestive angiodysplasia (n = 91). Results: The mean age of our patients was 64.95 ± 9.88 years [43 - 83] in group A, while in group B the mean age was 65.19 ± 14.29 years [40 - 91] with a clear male predominance in 72.5%. The majority of patients in group A were followed for prostate cancer in 33,8%, and 26.3% of patients in group B had chronic renal failure, followed by stomach cancer in 15.8%, and esophageal cancer in 10.5%. Clinical symptomatology was dominated by rectories in 40.2% in group A versus 46.8% in group B. Rectal involvement was dominated in group A in 98.1%, whereas in group B the lesions were mainly located in the stomach in 60.5%. The endoscopic evolution was favorable in all our patients with a clear improvement of rectal lesions and digestive angiodysplasia lesions. The total complication rate in our series was nil. Conclusion: Plasma Argon coagulation is a very effective method in the endoscopic treatment of digestive haemorrhages with good tolerability and a low complication rate. (AU)

Sporadic rectocolic polyps prevalence and management

Objective: To evaluate the prevalence of polyps and their treatments. Materials and Method: This is a retrospective study conducted in our department over 20 years and 3 months between January 2000 and March 2021. All patients with colorectal polyps who underwent endoscopic resection were included. We evaluated the resection techniques and the management of complications. Results: The total number of patients was 273, with a mean age of 57.26 ± 14.058 (18-90) and a M/W sex ratio of 2. The prevalence was 3.35% and the mean number of polyps was 1.33 ± 0.69. The most frequent symptoms were rectal bleeding (23.5%) and constipation (12.1%). The median size was 6 mm (4-12 mm). The left colonic location was the most frequent site (43%). All polyps were classified according to the Paris classification, with a predominance of sessile polyps in 45.75%, followed by pedunculated polyps, representing 42.4%. Endoscopic resection was performed either by biopsy forceps, polypectomy, or mucosectomy in 30.2%, 27.4%, and 25.4% of cases, respectively. Our study noted immediate bleeding in 1.5% of cases, and no perforations or late complications. All complications were treated endoscopically, and no patient required blood transfusion or surgical intervention. Conclusion: Endoscopic resection of rectocolic polyps is the ideal treatment for these lesions. In our department, the prevalence was 3.35%, the most used resection techniques were forceps resection and polypectomy, and the complication rate was 1.5%. (AU)
