Single-incision plus one port laparoscopic low anterior resection for mid-low rectal cancer-a video vignette

Efficacy and safety of reduced-port laparoscopic surgery versus conventional laparoscopic surgery for colorectal cancer

BACKGROUND

Laparoscopic radical resection has become the most important treatment for resectable colorectal cancer (CRC). However, there is still a lack of researches on the efficacy and safety of reduced-port laparoscopic surgery (RPLS) versus conventional laparoscopic surgery (CLS) in the treatment of CRC.

PATIENTS AND METHODS

From January 2019 to July 2022, 698 patients with CRC received surgical treatment in the Sixth Affiliated Hospital of Sun Yat-sen University were enrolled in this retrospective cohort study. Patients were divided into RPLS group (n = 220) and CLS group (n = 478) according to their surgical procedures. Propensity score matching (PSM) was used to adjust the differences in baseline characteristics. The incidence of perioperative outcomes and survival rates related results were analyzed after PSM.

RESULTS

Four hundred twenty-two patients were equally divided into RPLS group (n = 211) and CLS group (n = 211) after PSM. There were no statistically significant differences in overall survival (OS) and progression-free survival (PFS) between the two groups (P value was 0.773 and 0.579 respectively). The perioperative outcomes of patients between the two groups were comparable, except that patients in the RPLS group had a shorter postoperative hospital stay (P value < 0.001).

CONCLUSION

For patients with CRC, both RPLS and CLS might be acceptable surgical options. No significant differences in perioperative outcomes, PFS rates and OS rates were observed between the two groups. For certain cases, RPLS was superior to CLS in terms of postoperative recovery.

Advantages of the split-leg supine position single-port plus one laparoscopic surgery approach

The goal of this study was to compare the advantages of conventional laparoscopic surgery (CLS) and the split-leg supine position single-port plus one laparoscopic surgery (SSP SILS + 1) in esophageal surgery. This study enrolled 73 patients who previously underwent radical esophagectomy for esophageal cancer from August 2021 to February 2023. Among them, 36 patients underwent SSP SILS + 1, whereas the remaining 37 patients underwentCLS. Surgical time, bleeding volume, number of dissected lymph nodes, incision length, and postoperative abdominal pain score between the two groups of patients were compared using either the Student's t-test or chi-square test. Time of abdominal incision (1.4 ± 0.2 min vs. 5.2 ± 0.7 min, p < 0.001) was shorter in patients in the SSP SILS + 1 group compared with those in the CLS group. However, the average incision length was shorter in the SSP SILS + 1 group compared with that in the CLS group (35.4 ± 4.0 cm vs. 4.6 ± 4.1 cm, p < 0.001). Notably, the pain score on postoperative day (POD) 1 was lower in the SSP SILS + 1 group compared with that in the CLS group (5.7 ± 0.7 vs.6.3 ± 0.7, p = 0.001). The SCAR score was also lower in the SSP SILS + 1 group compared with that in the CLS group (3.5 ± 0.9 vs. 8.3 ± 1.4, p = 0.019). There was no significant difference in the number of dissected abdominal lymph nodes and positive lymph nodes (p > 0.01) between the two groups. The SSP SILS + 1 intervention offers multiple benefits over conventional surgical procedures, encompassing shorter incision length and pain scores on POD 1. In accelerated rehabilitation surgery for esophageal cancer, this surgical procedure demonstrated high safety, feasibility.
