Abstract
INTRODUCTION Lateral pelvic node dissection (LPND) poses significant technical challenges. Despite the advent of robotic surgery, determining the optimal minimally invasive approach remains a topic of debate. This study aimed to compare postoperative outcomes between robotic total mesorectal excision with LPND (R-LPND) and laparoscopic total mesorectal excision with LPND (L-LPND). METHODS This meta-analysis was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) 2020 and AMSTAR 2 (Assessing the Methodological Quality of Systematic Reviews) guidelines. Utilizing the RevMan 5.3.5 statistical package from the Cochrane Collaboration, a random-effects model was employed. RESULTS Six eligible studies involving 652 patients (316 and 336 in the R-LPND and L-LPND groups, respectively) were retrieved. The robotic approach demonstrated favourable outcomes compared with the laparoscopic approach, manifesting in lower morbidity rates, reduced urinary complications, shorter hospital stays, and a higher number of harvested lateral pelvic lymph nodes. However, longer operative time was associated with the robotic approach. No significant differences were observed between the two groups regarding major complications, anastomotic leak, intra-abdominal infection, neurological complications, LPND time, overall recurrence, and local recurrence. CONCLUSIONS In summary, the robotic approach is a safe and feasible alternative for Total Mesorectal Excision (TME) with LPND in advanced rectal cancer. Notably, it is associated with lower morbidity, particularly a reduction in urinary complications, a shorter hospital stay and increased number of harvested lateral pelvic nodes. The trade-off for these benefits is a longer operative time.

Abstract
PURPOSE This study aimed to explore the safety and feasibility of the modified lateral lymph node dissection (LLND) with routine resection of the visceral branches of internal iliac vessels (IIVs) for mid-low-lying rectal cancer. MATERIALS AND METHOD Consecutive patients undergoing LLND for rectal cancer were divided into the routine visceral branches of the IIVs resection group (RVR group) and the NRVR group (without routine resection). The main outcomes were postoperative complications and the number of lateral lymph nodes harvested. RESULTS From 2012 to 2021, a total of 75 and 57 patients were included in the RVR and NRVR group, respectively. The operative time was reduced in the RVR group (p = 0.020). No significant difference was observed between the two groups for the incidence of total, major, or minor postoperative complications. Pathologically confirmed LLNM were 24 (32%) patients in the RVR group and 12 (21.1%) in the NRVR group (p = 0.162). The number of lateral lymph nodes harvested had no significant difference between two groups (11 vs. 12, p = 0.329). CONCLUSION LLND with routine resection of visceral branches of IIVs is safe and feasible, which brings no major complication or long-term urinary disorder.

Abstract
BACKGROUND Near-infrared imaging with indocyanine green has been used to guide lateral lymph node dissection, yet its efficacy and benefits need further investigation. OBJECTIVE To investigate the efficacy and feasibility of near-infrared fluorescence imaging and angiography of the inferior vesical artery in laparoscopic lateral lymph node dissection. DESIGN A prospective nonrandomized controlled study. SETTINGS Single-center study. PATIENTS Patients with lower rectal cancer who underwent total mesorectal excision plus lateral lymph node dissection. MAIN OUTCOME MEASURES A cohort of 108 patients was enrolled. After propensity score matching, 29 patients in the near-infrared group and 50 patients in the non-near-infrared group were matched. The total number of harvested lateral lymph nodes, positive lateral lymph nodes, inferior vesical artery preservation, and postoperative urinary function were compared. RESULTS After propensity score matching, both groups had similar baseline characteristics. The total number of harvested lateral lymph nodes in the near-infrared group was significantly higher (12 vs 9, p = 0.013), but positive lateral lymph nodes were similar between the 2 groups (1 vs 1, p = 0.439). The inferior vesical artery preservation ratio was significantly increased with the aid of indocyanine green angiography (93.1% vs 56.0%, p < 0.001). The non-near-infrared group required more days for urinary catheter removal than the near-infrared group (5 vs 4, p = 0.046). Urinary recatheterization tended to occur more frequently in the non-near-infrared group, with a marginally significant trend (16% vs 0%, p = 0.059). The non-near-infrared group tended to have more cases with residual urine volume ≥50 mL than the near-infrared group (20.0% vs 3.4%, p = 0.087), especially in the bilateral dissection subgroup (41.2% vs 0%, p = 0.041). LIMITATIONS Small sample size. CONCLUSIONS Near-infrared imaging increased the number of harvested lateral lymph nodes, whereas real-time indocyanine green fluorescence angiography ensured the preservation of the inferior vesical artery and tended to improve postoperative urinary function.

Robotic versus laparoscopic approach for minimally invasive lateral pelvic lymph node dissection of advanced lower rectal cancer: a retrospective study comparing short-term outcomes. Tech Coloproctol 2023:10.1007/s10151-023-02818-x. [PMID: 37157049 DOI: 10.1007/s10151-023-02818-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2022] [Accepted: 04/27/2023] [Indexed: 05/10/2023]
Abstract
PURPOSE The importance of lateral pelvic lymph node dissection (LLND) for advanced low rectal cancer is gradually being recognized in Europe and the USA, where some patients were affected by uncontrolled lateral pelvic lymph node (LLNs) metastasis, even after total mesorectal excision (TME) with neoadjuvant chemoradiotherapy (CRT). The purpose of this study was thus to compare robotic LLND (R-LLND) with laparoscopic (L-LLND) to clarify the safety and advantages of R-LLND. METHODS Sixty patients were included in this single-institution retrospective study between January 2013 and July 2022. We compared the short-term outcomes of 27 patients who underwent R-LLND and 33 patients who underwent L-LLND. RESULTS En bloc LLND was performed in significantly more patients in the R-LLND than in the L-LLND group (48.1% vs. 15.2%; p = 0.006). The numbers of LLNs on the distal side of the internal iliac region (LN 263D) harvested were significantly higher in the R-LLND than in the L-LLND group (2 [0-9] vs. 1 [0-6]; p = 0.023). The total operative time was significantly longer in the R-LLND than in the L-LLND group (587 [460-876] vs. 544 [398-859]; p = 0.003); however, the LLND time was not significantly different between groups (p = 0.718). Postoperative complications were not significantly different between the two groups. CONCLUSION The present study clarified the safety and technical feasibility of R-LLND with respect to L-LLND. Our findings suggest that the robotic approach offers a key advantage, allowing significantly more LLNs to be harvested from the distal side of the internal iliac region (LN 263D). Prospective clinical trials examining the oncological superiority of R-LLND are thus necessary in the near future.

Prognostic Value of Lateral Pelvic Lymph Node Dissection for Rectal Cancer: A Meta-analysis. J Surg Res 2021; 267:414-423.

Abstract
BACKGROUND AND AIMS The benefit of lateral pelvic lymph node dissection (LPLD) for locally advanced rectal cancer remains controversial. This meta-analysis aimed to evaluate the prognostic value of LPLD in patients with locally advanced rectal cancer. METHODS We performed a systematic search in PubMed, Embase, and the Cochrane Library for publications comparing radical resection plus LPLD (LPLD group) with single radical resection (non-LPLD group) for locally advanced rectal cancer. A total of 15 studies satisfied our inclusion criteria and were assessed. Random-effects and fixed-effects meta-analytical models were used where indicated, and between-study heterogeneity was assessed. RESULTS LPLD significantly increased grade 3-4 postoperative complications (odds ratio [OR]1.44, 95% CI 1.03-2.02; P = 0.03) compared with non-LPLD. There were no significant differences in 5-y overall survival (hazard ratio = 0.90, 95% CI 0.77-1.05; P = 0.17), 5-y disease-free survival (hazard ratio 1.12, 95% CI 0.60-2.09; P = 0.73), local recurrence (OR 0.89, 95% CI 0.53-1.51; P = 0.68) or distant recurrence (OR 0.85, 95% CI 0.64-1.12; P = 0.24). CONCLUSIONS We found that LPLD significantly increased grade 3-4 postoperative complications but did not increase 5-y overall survival or 5-y disease-free survival compared with single radical resection for locally advanced rectal cancer. Furthermore, it did not decrease the local recurrence or distant recurrence rates. Thus, more multicenter large-scale randomized controlled trials should be conducted to further explore whether the long-term survival benefits of LPLD truly exist.

Abstract
INTRODUCTION Lateral pelvic recurrence can be a cause of local failure after surgery for low rectal cancer. Lateral lymph node dissection is often performed in East Asia for patients with enlarged lateral lymph nodes or because of the presence of risk factors. However, the outcomes of the conventional lateral lymph node dissection are unsatisfactory, with a considerably high local recurrence rate for patients with positive lateral nodes. Here, we introduce a modified technique to improve lateral nodes clearance. TECHNIQUE This modified technique has 4 key steps: 1) separation of the ureterohypogastric nerve fascia medially, 2) identification of the visceral pelvic fascia and dissection along the inferior vesical or vaginal veins down to the pelvic floor, 3) division of the distal ends of visceral vessels according to the orientation of ureterohypogastric nerve fascia and visceral pelvic fascia for better nerve preservation, and 4) en bloc dissection through a lateral approach over the surfaces of the sacral plexus and piriformis muscle to reveal the course of distal internal iliac vessels before the division of visceral veins. RESULTS Twenty-nine patients underwent laparoscopic lateral lymph node dissection successively with no conversion. The median blood loss for each lateral procedure was 37.5 mL (range, 0-300.0 mL). Eleven lateral nodes (median; range, 1-22 lateral nodes) were harvested for each lateral side. There was no perioperative mortality, and 4 patients developed major complications (Clavien-Dindo III-IV). CONCLUSION This modified technique characterized by the routine division of visceral vessels based on ureterohypogastric nerve fascia and visceral pelvic fascia is feasible and safe. It provides good lymph node harvest, autonomic nerve preservation, and improved bleeding control. Additional investigation is warranted to evaluate the safety, functional outcomes, and oncologic outcomes.

Long-term effects of laparoscopic lateral pelvic lymph node dissection on urinary retention in rectal cancer. Surg Endosc 2021; 36:999-1007. [PMID: 33616731 DOI: 10.1007/s00464-021-08364-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Accepted: 02/09/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND The addition of lateral pelvic lymph node dissection (LPLND) in rectal cancer surgery has been reported to increase the incidence of post-operative urinary retention. Here, we assessed the predictive factors and long-term outcomes of urinary retention following laparoscopic LPLND (L-LPLND) with total mesorectal excision (TME) for advanced lower rectal cancer. METHODS This retrospective single-institutional study reviewed post-operative urinary retention in 71 patients with lower rectal cancer who underwent L-LPLND with TME. Patients with preoperative urinary dysfunction or who underwent unilateral LPLND were excluded. Detailed information regarding patient clinicopathologic characteristics, post-void residual urine volume, and the presence or absence of urinary retention over time was collected from clinical and histopathologic reports and telephone surveys. Urinary retention was defined as residual urine > 100 mL and the need for further treatment. RESULTS Post-operative urinary retention was observed in 25/71 patients (35.2%). Multivariate analysis revealed that blood loss ≥ 400 mL [odds ratio (OR) 4.52; 95% confidence interval (CI) 1.24-16.43; p = 0.018] and inferior vesical artery (IVA) resection (OR 8.28; 95% CI 2.46-27.81; p < 0.001) were independently correlated with the incidence of urinary retention. Furthermore, bilateral IVA resection caused urinary retention in more patients than unilateral IVA resection (88.9% vs 47.1%, respectively; p = 0.049). Although urinary retention associated with unilateral IVA resection improved relatively quickly, urinary retention associated with bilateral IVA resection tended to persist over 1 year. CONCLUSION We identified the predictive factors of urinary retention following L-LPLND with TME, including increased blood loss (≥ 400 mL) and IVA resection. Urinary retention associated with unilateral IVA resection improved relatively quickly. L-LPLND with unilateral IVA resection is a feasible and safe procedure to improve oncological curability. However, if oncological curability is guaranteed, bilateral IVA resection should be avoided to prevent irreversible urinary retention.

Abstract
In the era of neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision, overall oncological outcomes after curative resection of rectal cancer are excellent, with local recurrence rates as low as 5–10%. However, lateral nodal disease is a major cause of local recurrence after neoadjuvant chemoradiotherapy/radiotherapy and total mesorectal excision. Patients with lateral nodal disease have a local recurrence rate of up to 30%. The oncological benefits of lateral pelvic lymph node dissection (LPLND) in reducing local recurrence, particularly in the lateral compartment, have been demonstrated. Although LPLND is not standard in Western countries, technical improvements in minimally invasive surgery have resulted in rapid technical standardization of this complicated procedure. The feasibility and short- and long-term outcomes of laparoscopic and robotic LPLND have been reported widely. A minimally invasive approach has the advantages of less bleeding and providing a better surgical view of the deep pelvic anatomy than an open approach. With precise autonomic nerve preservation, postoperative genitourinary dysfunction has been reported to be minimal. We review recent evidence on the management of lateral nodal disease in rectal cancer and technical improvements of LPLND, focusing on laparoscopic and robotic LPLND.
