Single-port laparoscopic appendectomy using a needle-type grasping forceps for selective adult patients with acute uncomplicated appendicitis

A brief overview of single-port laparoscopic appendectomy as an optimal surgical procedure for patients with acute appendicitis: still a long way to go

Single-port laparoscopic appendectomy (SPLA) has become a good alternative to the traditional surgical treatment of acute appendicitis, due to its advantages of small incision, mild postoperative pain, short hospital stay, and good cosmetic effect. However, the further application of SPLA has been restricted by its relatively long operating time, high level of operating difficulty, and increased equipment and technical requirements. Clinical teams worldwide have attempted to improve and optimize SPLA technical protocols and equipment to maintain stable intraoperative pneumoperitoneal pressure, improve the 'triangle relationship' of operating angles, and develop new surgical procedures with less trauma and higher cost-effectiveness. Here, new SPLA techniques reported over the past decade are reviewed and compared, with the aim of providing new insights into technical improvements, equipment upgrades and clinical studies in the coming years.

Single-port laparoscopic appendectomy using a needle-type grasping forceps compared with conventional three-port laparoscopic appendectomy for patients with acute uncomplicated appendicitis: a single-center retrospective study

Objective

To compare the clinical outcomes between single-port laparoscopic appendectomy using a needle-type grasping forceps (SLAN) and conventional three-port laparoscopic appendectomy (CLA) for patients with uncomplicated appendicitis.

Methods

We retrospectively collected clinical data of patients with uncomplicated appendicitis who underwent SLAN or CLA from May 2019 to May 2021 in our center. The patients’ baseline characteristics, perioperative outcomes, and follow-up data were compared between the two groups. Additionally, baseline characteristics were compared with postoperative outcomes in the SLAN group.

Results

Ninety-six patients were enrolled (SLAN group, n = 32; CLA group, n = 64). The SLAN group had a shorter hospital stay, lower 24-hour postoperative visual analogue scale scores, shorter postoperative fasting time, lower frequency of antibiotic administration, and longer operative time than the CLA group. In the SLAN group, younger patients had a longer appendix and male patients had a thicker appendix; additionally, patients with an appendiceal diameter of 0.6 to 1.0 cm had a longer postoperative hospital stay and higher frequency of antibiotic administration.

Conclusions

Compared with CLA, SLAN may be less invasive, provide faster postoperative recovery, and result in better cosmesis for patients with uncomplicated appendicitis. Further research should be performed to evaluate the long-term outcomes.
