Aim: One of the most serious complications in modern colorectal surgery is the occurrence of an anastomotic dehiscence. The aim of this study was to evaluate the role of preoperative red cell distribution width (RDW) and mean platelet volume (MPV) as predictors of anastomotic dehiscence in elective surgery for colorectal cancer.
Materials And Methods: Forty-two patients with a clinically manifested anastomotic dehiscence after oncological colorectal surgery, and 42 controls matched for age, sex, pathological stage and tumor localization were enrolled. Correlations between the preoperative RDW and MPV values and anastomotic dehiscence were investigated.
Results: Both the median RDW value (14.4 % vs 13.1%; p=0.007) and the median MPV value (8.0 fL vs 7.5 fL; p=0.037) were significantly higher in patients with anastomotic dehiscence than in those without. In multiple regression analysis only the RDW remained significantly associated with anastomotic dehiscence.
Conclusions: The preoperative values of RDW may be useful in predicting anastomotic damage in elective oncological surgery.
Key Words: Anastomotic Dehiscence, MPV, RDW.

Anastomotic leakage (AL) is one of the most devastating complications after colorectal surgery. The verification of the adequate perfusion of the anastomosis is essential to ensuring anastomosis integrity following colonic resections. This study aimed to evaluate the efficacy of measuring the electrical activity of the colonic muscularis externa at an anastomosis site for perfusion analysis following colorectal surgery.

BACKGROUND Terminal ileum (TI) anastomoses present challenges due to anatomical features and pressure from the ileocecal valve (ICV). The use of negative-pressure wound therapy (NPWT) is commonly used to treat chronic skin ulcers. Its use for temporary abdominal closure following anastomosis is controversial but has shown promise in patients with inflammatory or vascular disease.

Background Wound dehiscence (WD) is a major postoperative complication following abdominal surgeries, particularly exploratory laparotomy. Identifying preoperative risk factors and using predictive tools, such as the Rotterdam Risk Index (RRI), are crucial for early intervention and improving patient outcomes. This study aimed to evaluate the risk factors associated with WD and assess the predictive accuracy of the RRI in a cohort of patients undergoing abdominal surgeries.

Introduction: In critically ill surgical patients treated with open abdomen and negative pressure therapy (OA/NPT), the association between nutritional support and clinical outcome is still controversial. The main objective of this study was to assess the effect of enteral nutritional support during the acute phase (i.e.

These factors can significantly increase the complexity of surgery and the risk of both immediate and delayed complications, which can occur intraoperatively or postoperatively. Objective: the aim of this study was to retrospectively analyze the causes, diagnostic methods, and management of complications in patients who underwent surgery for rectal cancer.
