Aim: To evaluate the effect of local surgical adhesive glue (albumin/glutaraldehyde-Bioglue) on the healing of colonic anastomoses in rats.
Methods: Forty Albino-Wistar male rats were randomly divided into two groups, with two subgroups of ten animals each. In the control group, an end-to-end colonic anastomosis was performed after segmental resection. In the Bioglue group, the anastomosis was protected with extraluminar application of adhesive glue containing albumin and glutaraldehyde. Half of the rats were sacrificed on the fourth and the rest on the eighth postoperative day. Anastomoses were resected and macroscopically examined. Bursting pressures were calculated and histological features were graded. Other parameters of healing, such as hydroxyproline and collagenase concentrations, were evaluated. The experimental data were summarized and computed from the results of a one-way ANOVA. Fisher's exact test was applied to compare percentages.
Results: Bursting pressures, adhesion formation, inflammatory cell infiltration, and collagen deposition were significantly higher on the fourth postoperative day in the albumin/glutaraldehyde group than in the control group. Furthermore, albumin/glutaraldehyde significantly increased adhesion formation, inflammatory cell infiltration, neoangiogenesis, and collagen deposition on the eighth postoperative day. There was no difference in fibroblast activity or hydroxyproline and collagenase concentrations.
Conclusion: Albumin/glutaraldehyde, when applied on colonic anastomoses, promotes their healing in rats. Therefore, the application of protective local agents in colonic anastomoses leads to better outcomes.

Background: Deloyers technique addresses challenges in restoring bowel continuity following extended left hemicolectomies. Despite being first described in 1958, the technique remains underutilized, with limited data on long-term outcomes.
Objective: To evaluate the indications, surgical and functional outcomes of Deloyers technique and review existing literature.

Background: Optimal selection of anastomosis technique is crucial in colectomy surgeries to ensure success and minimize postoperative complications. Various methods, both manual and stapler-assisted, are employed for intestinal anastomosis. This study aims to compare two surgical methods of intestinal anastomosis through macroscopic and microscopic examination.

Anastomotic leak occurrence is a severe complication after colorectal surgery. Considering the difficulty of treating these leaks and their impact on patient care, there is a strong need for an efficient prevention strategy. We evaluated a combination of extracellular vesicles (EVs) from rat adipose-derived stromal cells with a thermoresponsive gel, Pluronic® F127 (PF-127) to prevent anastomotic leaks.

Background: There is limited data within the urologic literature regarding bowel complications and leak rates following surgery requiring ileocolic anastomoses such as right colon pouch (RCP) and continent cutaneous ileocecocystoplasty (CCIC). We aimed to establish ileocolic anastomotic leak rates in urologic reconstructive surgery and determine bowel-related complications following RCP and CCIC surgeries.
Methods: We reviewed adult patients who underwent RCP or CCIC (2010-2022), investigating patient characteristics, perioperative variables, and outcomes.

Familial adenomatous polyposis (FAP) is a rare inherited disorder characterized by numerous adenomatous polyps throughout the colon and rectum, leading to a significantly increased risk of colorectal cancer. We present the case of a 19-year-old male patient with a known family history of FAP who presented with recurrent lower abdominal pain, altered bowel habits, and rectal bleeding. Initial examination identified rectal polyps, and subsequent colonoscopy revealed multiple adenomatous polyps.
