Abstract
BACKGROUND: Despite emerging evidences on the feasibility and efficacy of single-incision laparoscopic appendectomy (SILA) for managing simple appendicitis, advancing its use for treating complicated appendicitis remains unwarranted. This study aimed to evaluate the surgical outcome of SILA compared with that of standard multiport laparoscopic appendectomy (MPLA) in the management of complicated appendicitis. METHODS: Between July 2013 and September 2017, 40 patients who underwent SILA and 150 patients who underwent MPLA for the treatment of complicated appendicitis, defined as AAST grades II-V, were recruited for this study. The demographic characteristics, intraoperative and recovery parameters were retrospectively recorded. No routine drainage was placed in the SILA group. RESULTS: SILA was smoothly performed without requiring conversion to MPLA. No significant difference was observed between the 2 groups in demography and preoperative severity. The operation duration was approximately 8 min shorter in the SILA group than in the MPLA group, without a statistical difference (60.03 ± 21.01 vs. 68.04 ± 32.03 min, p = 0.222). The recovery parameters, including soft diet intake and postoperative hospitalization, were more favorable in the SILA group (p < 0.001). Despite the absence of routine drainage in the SILA group, only 1 patient developed an intra-abdominal hematoma necessitating further computed tomography-guided drainage. CONCLUSION: SILA is safe and feasible for the management of complicated appendicitis. SILA had non-inferior results to MPLA in terms of time to resume oral intake and postoperative hospital stay. Furthermore, this study posted a question on the concept of routine postoperative drainage in complicated appendicitis.
