COMPARISON THE FREQUENCY OF WOUND INFECTION IN SIMPLE LIGATION OF APPENDICULAR STUMP VERSUS STUMP INVAGINATION AFTER APPENDICECTOMY

ABSTRACT
Introduction: Acute appendicitis is the most common abdominal emergency surgical disease. Appendicectomy remains
the standard treatment of acute appendicitis, which is performed by both open and laparoscopic approaches.
Objective: To compare the frequency of wound infection in simple ligation of appendicular stump versus stump invagination
after appendicectomy.
Materials and Methods: Study design was randomized control trial and the duration of the study was 6 months in
which a total of 240 (120 in each group), 80% power of test, 2.3% p1 proportion of simple ligation group, 10% proportion
of stump invigilation group, 95% confidence interval under WHO sample size calculation. More over consecutive
(non-probability) sampling technique was used for sample collection. Study was conducted at Khyber Teaching Hospital,
Peshawar at Surgery Department from December 2015 to June 2016.
Our study shows that mean age in Group A (simple ligation) was 32 years with standard deviation ± 1.26 and the
mean age in Group B (stump invagination) was 35 years with standard deviation ± 2.73. In Group A (simple ligation)
55% patients were male and 45% patients were female while in Group B (stump invagination) 58% patients were male
and 42% patients were female. In Group A (simple ligation) 6% patients had wound infection while in Group B (stump
invagination) 12% patients had wound infection.
Conclusion: Our study concludes that simple ligation of appendicular stump is better than stump invagination in term
of preventing post-operative wound infection.
Key Words: Appendicectomy, stump invagination, simple ligation
