Feasibility of single-port laparoscopic appendectomy for retrocecal appendicitis: A propensity score-matched study with multi-port laparoscopic appendectomy

Figure 1 Acute appendicitis located in retrocecal position. This figure is generated based on a case performed at Konyang University Hospital.

Figure 2 Flow charts of patient selection process. SPLA: Single-port laparoscopic appendectomy; MPLA: Multi-port laparoscopic appendectomy.

Figure 4 Histogram for comparing operation time and estimated blood loss between the single-port laparoscopic appendectomy group and multi-port laparoscopic appendectomy group. A: Histogram of operation time for single-port laparoscopic appendectomy (SPLA); B: Histogram of operation time for multi-port laparoscopic appendectomy (MPLA); C: Histogram of estimated blood loss (EBL) for SPLA; D: Histogram of EBL for MPLA. SPLA: Single-port laparoscopic appendectomy; MPLA: Multi-port laparoscopic appendectomy; EBL: Estimated blood loss.
