Factors Influencing Leaks in Primary Intestinal Anastomoses: An Observational Study

Area of Science:

• Gastrointestinal Surgery
• Surgical Complications
• Patient Risk Factors

Background:

• Anastomotic leak (AL) is a significant complication in gastrointestinal surgery.
• AL increases patient morbidity, hospitalization duration, and mortality rates.
• Primary intestinal anastomosis is particularly susceptible to AL.

Purpose of the Study:

• To identify and evaluate patient, surgical, and perioperative factors linked to anastomotic leaks.
• To assess the association between specific comorbidities and AL development.
• To determine predictive factors for anastomotic leaks in primary intestinal anastomosis.

Main Methods:

• Observational study involving 70 patients undergoing primary intestinal anastomosis.
• Data collection included demographics, comorbidities, surgical details, and outcomes.
• Logistic regression and ROC analysis were used to identify predictive factors.

Main Results:

• The overall incidence of AL was 23.3%.
• Higher BMI, renal disease, hypertension, and diabetes were significantly associated with AL.
• BMI was identified as an independent predictor; BMI and CRP showed predictive utility.

Conclusions:

• Elevated BMI and comorbidities (renal disease, hypertension, diabetes) are key risk factors for AL.
• Preoperative optimization and risk stratification based on these factors can enhance surgical outcomes.
• Further validation in larger, multicentric studies is recommended.
