Summary
Bipolar electrocautery for appendix stump closure in rats proved safe and effective, showing better healing and no leakage compared to traditional ligation. This laparoscopic technique offers a viable alternative for appendiceal stump management.
Area of Science:
- Surgical Innovation
- Animal Models in Research
- Gastrointestinal Surgery
Background:
- Evaluating novel surgical techniques is crucial for improving patient outcomes.
- Appendiceal stump management remains a critical aspect of appendectomy.
- Laparoscopic bipolar electrocautery presents a potential alternative to traditional stump closure methods.
Purpose of the Study:
- To assess the efficacy and safety of using only laparoscopic bipolar electrocautery for appendiceal stump closure in a rat model.
- To compare the outcomes of electrocautery stump closure with traditional silk ligation.
- To evaluate the long-term integrity and healing of the appendiceal stump.
Main Methods:
- Forty female Wistar-Albino rats were divided into three groups: silk ligation, bipolar electrocautery, and a control group for early burst pressure measurement.
- Appendiceal stumps were either ligated with silk suture or coagulated using bipolar electrocautery.
- Burst pressure of the stump was measured at 15 days post-procedure (Groups I and II) or during the initial laparotomy (Group III).
- Histopathological evaluation assessed stump healing, inflammation, and complications like abscess or necrosis.
Main Results:
- No intra-abdominal complications such as leakage, abscess, or obstruction were observed in any group.
- Bipolar electrocautery stumps demonstrated significantly better epithelial regeneration (80%) compared to ligated stumps, which showed severe inflammation, abscess, and necrosis.
- Both ligated and electrocautery stumps withstood high intracecal pressure (30 cmH2O) without bursting, indicating secure closure.
- Early burst pressure in the non-relaparotomy group (Group III) was significantly lower than in the groups assessed at 15 days.
Conclusions:
- Closure of the appendiceal stump with bipolar electrocautery is a safe and feasible method in this experimental model.
- Electrocautery resulted in superior stump healing and reduced inflammatory changes compared to silk ligation.
- The findings suggest that laparoscopic bipolar electrocautery is a promising technique for appendiceal stump management, minimizing complications and promoting better tissue regeneration.
