“…Second, endoscopists have more direct access to the appendiceal orifice lesion and the appendix, which could facilitate the identification of the appendix and reduce potential injuries to surrounding tissues, especially in patients with previous abdominal surgery. Third, the ETA technique leaves no scar on the abdomen and has no complications associated with surgical incision, such as incisional hernia and wound infection 18 .…”

Background Endoscopic transcecal appendectomy (ETA) has been reported as a minimally invasive alternative procedure for lesions involving the appendiceal orifice. The aim of this case series study was to evaluate the feasibility, safety, and effectiveness of ETA for lesions at the appendiceal orifice. Methods This retrospective study included consecutive patients with appendiceal orifice lesions who underwent ETA between December 2018 and March 2021. The primary outcome was technical success. The secondary outcomes included postoperative adverse events, postoperative hospital stay, and recurrence. Results 13 patients with appendiceal orifice lesions underwent ETA during the study period. The median lesion size was 20 mm (range 8–50). Lesions morphologies were polypoid lesions (n = 5), laterally spreading tumors (n = 4), and submucosal lesions (n = 4). Technical success with complete resection was achieved in all 13 cases. There were no postoperative bleeding, perforation, or intra-abdominal abscess. The median length of hospital stay after ETA was 8 days (range 6–18). There was no tumor recurrence during a median follow-up of 17 months (range 1–28). Conclusions ETA is feasible, safe, and effective for complete resection of appendiceal orifice lesions. Larger, multicenter, prospective studies are needed to further assess this technique.

Introduction: Low-grade appendiceal mucinous neoplasm (LAMN) is a rare disease, and its clinical course varies from an incidental finding without symptoms to pseudomyxoma peritonei. Furthermore, there are few established treatment guidelines. This study was designed to confirm the outcomes in patients diagnosed with LAMN who underwent single-incision laparoscopic caecal pole resection. Patients and Methods: This study was conducted on pathologically confirmed LAMNs from patients who underwent surgery at a single centre, a tertiary institution, from July 2016 to August 2022. Patients diagnosed with LAMN as a result of biopsy were included. All surgeries were performed with single-incision laparoscopic caecal pole resection by a single surgeon. Results: A total of 70 patients were included. The median age was 65.5 years and 36 (51.4%) patients were female. The baseline carcinoembryonic antigen (CEA) was 8.08 ng/mL (0.76–148.11). The mean maximum diameter was 29.4 mm (7–70) and calcification was seen in 22 cases on pre-operative computed tomography (CT). As a result of histological examination, all patients were marginally negative. The larger the tumour size, the higher the CEA was (P = 0.011), and it was often accompanied by calcification (P = 0.021). In addition, tumour size and CEA showed a positive partial correlation with each other (r = 0.318, P = 0.018). The overall median follow-up period was 22.7 months (2–60). One case had suspected of recurrence on CT scan performed at 33 months following the surgery, but there were no related symptoms. Conclusion: Single-port laparoscopic caecal pole resection without margin involvement in LAMN was safe and feasible, and showed a favourable long-term outcome.
