Background Acute appendicitis is the most frequent surgical emergency encountered worldwide. This study was conducted to compare the efficacy of Tzanakis score and Alvarado score in diagnosing acute appendicitis.Objectives The aim of this study is to compare the efficacy of Tzanakis scoring system with Alvarado scoring system in diagnosing AA.Methods This was a retrospective and nonrandomized observational study conducted in Dhulikhel hospital. It included 200 clinically diagnosed cases of acute appendicitis who underwent emergency open or laparoscopic appendectomy during the year 2012. Final diagnosis of acute appendicitis was based on histological findings given by pathologist.Results The sensitivity, specificity, positive predictive value and negative predictive value of Tzanakis score was 86.9%, 75.0, 97.5% and 33.3% respectively. The sensitivity, specificity, positive predictive value and negative predictive value of Alvarado score was 76.0%, 75.0%, 97.2% and 21.4% respectively. Negative appendectomy was 8.0%. Conclusion Tzanakis scoring system is an effective scoring system in diagnosing acute appendicitis.Kathmandu University Medical Journal Vol.12(1) 2014: 48-50
Background: In the era of minimal invasive surgery, hernia repair has seen a paradigm shift from open to laparoscopic technique. However, superiority of laparoscopic repair over open repair is still controversial. Available literatures have shown laparoscopic technique to be better in term of post-operative pain and early return to work.Methods: In this prospective study, a total of 102 patients aged 21-78 years with inguinal hernia were recruited and enrolled into two comparative groups, namely Lichtenstein’s and Transabdominal pre-peritoneal, and each group containing 51 participants. Hospital ethical committee approval and written informed consent from patients was obtained. Primarily, the duration of operation, post-operative pain and complication, and quality of life after surgery was compared between the two different approaches of hernia repair.Results: The study results demonstrated a statistically significant superiority of trans abdominal pre-peritoneal repair over Lichtenstein’s hernioplasty in terms of post operative pain (2.00±0.63 vs 3.90±0.74 VAS score, P value<0.001), hospital stay (2.33±0.62 vs 2.96±0.20 days, P value <0.001) and quality of life with early return to normal work (13.39±0.60 vs 17.88±0.86 days, P value <0.001); whereas a prolonged operative time was seen in transabdominal pre-peritoneal repair (96.08±27.08 vs 42.55±5.95 mins, P value <0.001). Conclusions: This study has shown that transabdominal pre-peritoneal repair is better than Lichtenstein’s in respect to post-operative pain, quality of life and post-operative complication. However, it has prolonged operative duration than conventional method.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
