ABSTRACT
(1) Background: Familial adenomatous polyposis (FAP) is a hereditary condition characterized by the development of numerous adenomas in the large intestine, often necessitating colectomy due to an elevated risk of colorectal cancer. Despite surgical intervention, adenomas frequently recur, underscoring the importance of ongoing surveillance. This study evaluates the outcomes of a 12-year endoscopic follow-up after colectomy and gastrointestinal reconstruction for FAP. (2) Methods: A retrospective analysis was conducted on 41 FAP patients who underwent at least one postoperative endoscopic examination. Assessments of the pouch or rectum were performed every 12-18 months following ileorectal anastomosis and every 18-24 months after ileal pouch-anal anastomosis. Follow-up biopsies were assessed using the adopted Spigelman classification. (3) Results: Postoperative pathology revealed invasive colorectal cancer in three patients. Abdominoperineal resection was performed in two cases due to secondary invasive carcinoma, and one T1 tumor was radically removed with ESD. One patient underwent radical pouch excision following a nodal pelvic recurrence of rectal cancer. Over a 12-year observation period, the mean Spigelman score increased by 2 points, and the proportion of patients with low-grade polypoid lesions decreased. The quantity or size of polyps increased in 24 patients, decreased in 8 patients, and remained stable in 9 patients. In four patients, granular, laterally spreading tumors were discovered in the rectal stump. (4) Conclusions: Regular endoscopic surveillance in FAP patients facilitates early identification of neoplastic and inflammatory changes. The downstaging potential highlights the effectiveness of early interventions. While the Spigelman classification assessed polyps well, it did not predict cancer occurrence. A notable number of patients had invasive cancer at the time of surgery, underscoring the importance of early surgical qualification, which is particularly crucial for identifying upstaging or secondary cancer.
ABSTRACT
Acute kidney injury (AKI) and sudden exacerbation of chronic kidney disease (CKD) frequently necessitate urgent kidney replacement therapy (UKRT). Peritoneal dialysis (PD) is recognized as a viable modality for managing such patients. Urgent-start peritoneal dialysis (USPD) may be associated with an increased number of complications and is rarely utilized. This review examines recent literature investigating the clinical outcomes of USPD in CKD and AKI. Relevant research was identified through searches of the MEDLINE (PubMed), Scopus, Web of Science, and Google Scholar databases using MeSH terms and relevant keywords. Included studies focused on the emergency use of peritoneal dialysis in CKD or AKI and reported treatment outcomes. While no official recommendations exist for catheter implantation in USPD, the impact of the technique itself on outcomes was found to be less significant compared with the post-implantation factors. USPD represents a safe and effective treatment modality for AKI, although complications such as catheter malfunctions, leakage, and peritonitis were observed. Furthermore, USPD demonstrated efficacy in managing CKD, although it was associated with a higher incidence of complications compared to conventional-start peritoneal dialysis. Despite its cost-effectiveness, PD requires greater technical expertise from medical professionals. Close supervision and pre-planning for catheter insertion are essential for CKD patients. Whenever feasible, an urgent start should be avoided. Nevertheless, in emergency scenarios, USPD does remain a safe and efficient approach.
ABSTRACT
Introduction: Most anastomotic leaks in the upper gastrointestinal (GI) tract can be treated with minimally invasive techniques dominated by endoluminal vacuum therapy (EVT) or stent implantation. Chronic leaks often require additional solutions, such as tissue adhesives or cellular growth stimulants. Aim: To present a treatment strategy for postoperative leakage of upper GI anastomoses with noninvasive procedures. Material and methods: A group of 19 patients treated in the period 2015-2023 with postoperative upper GI tract leakage was enrolled for endoscopic treatment. The indication for the therapy was anastomotic dehiscence not exceeding half of the circumference and the absence of severe septic complications. All patients were managed using endoscopic vacuum therapy (EVT) or a self-expanding stent while persistent fistulas were additionally treated with alternative methods. Results: The EVT was successfully implemented in 13 cases, but 7 patients required alternative methods to achieve definitive healing. Self-expanding stent placement was performed in 6 patients; however, in 3 cases a periprosthetic leakage occurred. In this group, 2 patients had the stent removed and the third one died due to septic complications. Post-treatment stenosis was identified in 5 patients after EVT that required balloon dilation with acceptable resolution in all cases. Conclusions: Early detected anastomotic dehiscence limited to half of the circumference most effectively responded to the noninvasive treatment. Nutritional support as well as complementary endoscopic solutions such as tissue adhesives, growth stimulants and hemostatic clips increase the percentage of complete healing.
