1
Comparison between Type 3 without prior appendectomy and others, using Fisher’s exact test
2
One patient developed delayed local peritonitis, resolved with just antibiotics
3
One patient developed postoperative peritonitis requiring additional surgery
4
One patient with per-operative perforation developed peritonitis and postoperative appendicitis
5
One patient had R1 resection with a synchronous invasive adenocarcinoma in the descending colon and underwent additional surgery, Postoperative complication-related surgery rate is 6.3 % (2 cases).
6
Postoperative complication related surgery rate is 6.3% (2 cases).
