Long-term outcomes of single-incision plus one-port laparoscopic surgery versus conventional laparoscopic surgery for rectosigmoid cancer: a randomized controlled trial. BMC Cancer 2023; 23:1204. [PMID: 38062421 PMCID: PMC10702022 DOI: 10.1186/s12885-023-11500-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2022] [Accepted: 10/09/2023] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Though our previous study has demonstrated that the single-incision plus one-port laparoscopic surgery (SILS + 1) is safe and feasible for sigmoid colon and upper rectal cancer and has better short-term outcomes compared with conventional laparoscopic surgery (CLS), the long-term outcomes of SILS + 1 remains uncertain and are needed to evaluated by an RCT. METHODS Patients with clinical stage T1-4aN0-2M0 rectosigmoid cancer were enrolled. The participants were randomly assigned to either SILS + 1 (n = 99) or CLS (n = 99). The 3-year DFS, 5-year OS, and recurrence patterns were analyzed. RESULTS Between April 2014 and July 2016, 198 patients were randomly assigned to either the SILS + 1 group (n = 99) or CLS group (n = 99). The median follow-up in the SILS + 1 group was 64.0 months and in CLS group was 65.0 months. The 3-year DFS was 87.8% (95% CI, 81.6-94.8%) in SILS + 1 group and 86.9% (95% CI, 81.3-94.5%) in CLS group (hazard ratio: 1.09 (95% CI, 0.48-2.47; P = 0.84)). The 5-year OS was 86.7% (95% CI,79.6-93.8%) in the SILS + 1 group and 80.5% (95% CI,72.5-88.5%) in the CLS group (hazard ratio: 1.53 (95% CI, 0.74-3.18; P = 0.25)). There were no significant differences in the recurrence patterns between the two groups. CONCLUSIONS We found no significant difference in 3-year DFS and 5-year OS of patients with sigmoid colon and upper rectal cancer treated with SILS + 1 vs. CLS. SILS + 1 is noninferior to CLS when performed by expert surgeons. TRIAL REGISTRATION ClinicalTrials.gov: NCT02117557 (registered on 21/04/2014).

Short-term and long-term outcomes of single-incision plus one-port laparoscopic surgery for colorectal cancer: a propensity-matched cohort study with conventional laparoscopic surgery. BMC Gastroenterol 2023; 23:420. [PMID: 38030976 PMCID: PMC10687908 DOI: 10.1186/s12876-023-03058-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Accepted: 11/22/2023] [Indexed: 12/01/2023] Open
Abstract
BACKGROUND Single-incision plus one-port laparoscopic surgery (SILS + 1) has been demonstrated to be minimally invasive while possessing better cosmesis and less pain compared with conventional laparoscopic surgery (CLS). However, SILS + 1 as an alternative to CLS for colorectal cancer is still controversial. METHODS A total of 1071 patients who underwent curative laparoscopic surgery for colon cancer between 2015 and 2018 were included. Of these patients, 258 SILS + 1 cases and 516 CLS cases were analyzed using propensity score matching. The baseline characteristics, surgical outcomes, pathologic findings and recovery course, morbidity and mortality within postoperative 30 days and 3-year disease-free and overall survival were compared. RESULTS Baseline characteristics were balanced between the groups. The mean operating time was significantly shorter in SILS + 1 group, with less estimated blood loss. Tumor size, tumor differentiation, number of harvested lymph nodes, resection margin and pathologic T, N, TNM stage was similar between the groups. There was no significant difference in overall perioperative complications. Uni- and multivariate analyses revealed that SILS + 1 was not a risk factor for complications. Postoperatively, SILS + 1 group showed faster recovery than CLS group in terms of ambulation, bowel function, oral intake and discharge. The 3-year disease-free survival rates of SILS + 1 and CLS groups were 90.1% and 87.3%(p = 0.59), respectively and the 3-year overall survival rates were 93.3% vs. 89.8%(p = 0.172). DISCUSSION Our study revealed that SILS + 1 is safe, feasible, oncologically efficient, and may be considered as a surgical option for selected patients with colorectal cancer.

Single-incision versus conventional multiport laparoscopic surgery for colorectal cancer: a meta-analysis of randomized controlled trials and propensity-score matched studies. Int J Colorectal Dis 2021; 36:1407-1419. [PMID: 33829313 DOI: 10.1007/s00384-021-03918-6] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 03/24/2021] [Indexed: 02/08/2023]
Abstract
PURPOSE To compare single-incision laparoscopic surgery (SILS) and multiport laparoscopic surgery (MLS) for colorectal cancer in terms of short- and long-term outcomes. METHODS A systematic literature search was performed in PubMed, Web of Science, and Embase. Randomized controlled trials (RCTs) and propensity-score matched (PSM) studies comparing SILS and MLS for colorectal cancer were enrolled. Outcomes of interests included intraoperative, postoperative, pathological, and survival outcomes. RESULTS Sixteen studies (6 RCTs and 10 PSM studies) published between 2012 and 2020 with a total of 2425 patients were enrolled. Compared with MLS, SILS was associated with less postoperative pain at postoperative day (POD) 1 (P = 0.02, MWD = -0.73, 95%CI: -1.37, -0.09) and POD2 (P < 0.001, MWD= -1.10, 95%CI: -1.45, -0.74) and shorter length of total incision length (P < 0.001, MWD = -3.31, 95%CI: -3.95, -2.67). No differences were observed in terms of operative time, blood loss, intraoperative and postoperative complications, incision hernia, and pathological or survival outcomes between SILS and MLS. Subgroup analysis for right-sided colon cancer, sigmoid colon cancer, and rectosigmoid colon cancer showed that the SILS group was only associated with less postoperative pain and shorter total incision length. The surgical and pathological outcomes were comparable between SILS and MLS. CONCLUSIONS SILS is a beneficial alternative to MLS in select colorectal cancer patients, especially for right-sided colon cancer, sigmoid colon cancer, and rectosigmoid cancer, with better cosmetic effects and less postoperative pain. Simultaneously, SILS does not compromise intraoperative and postoperative complications, surgical quality, or long-term outcomes.

A learning curve in using organ retractor for single-incision laparoscopic right colectomy. Sci Rep 2021; 11:6546. [PMID: 33753808 PMCID: PMC7985516 DOI: 10.1038/s41598-021-86168-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Accepted: 02/25/2021] [Indexed: 12/26/2022] Open
Abstract
Single-incision laparoscopic surgery (SILS) has the potential to improve perioperative outcomes, including less postoperative pain, shorter operation time, less blood loss, and shorter hospital stay. However, SILS is technically difficult and needs a longer learning curve. Between April 2016 and September 2019, a total of 198 patients with clinical stage I/II right colon cancer underwent curative resection. In the case of the SILS approach, an organ retractor was usually used to overcome SILS-specific restrictions. The patients were divided into two groups by surgical approach: the SILS with organ retractor group (SILS-O, n = 33) and the conventional laparoscopic surgery group (LAC, n = 165). Clinical T status was significantly higher in the LAC group (p = 0.016). Operation time was shorter and blood loss was lower in the SILS-O group compared to the LAC group (117 vs. 197 min, p = 0.027; 10 vs. 25 mL, p = 0.024, respectively). In the SILS-O group, surgical outcomes including operation time, blood loss, number of retrieved lymph nodes, and postoperative complications were not significantly different between those performed by experts and by non-experts. Longer operation time (p = 0.041) was significantly associated with complications on univariate and multivariate analyses (odds ratio 2.514, 95%CI 1.047–6.035, p = 0.039). SILS-O was safe and feasible for right colon cancer. There is a potential to shorten the learning curve of SILS using an organ retractor.

Abstract
The aim of the current systematic review was to compare the short-term clinical and oncological outcomes of single-port surgery (SPS) to multi-port surgery (MPS) for rectal cancer in MEDLINE, PubMed and Cochrane Library from January 2010 to December 2018. A total of 5 clinical controlled studies composed one randomized pilot study and four non-randomized studies with a total of 461 patients were analyzed after a systematic review. A total of 125 patients (27.1%) underwent SPS and 336 patients (72.9%) underwent MPS for rectal cancer. The rate of conversion to open surgery was lower in the SPS group compared with the MPS group (0.8 vs. 5.4%, respectively). A total of 16.8% of patients in the SPS group required an additional port to complete the operation. The morbidity rate was lower in the SPS group compared with the MPS group (28.0 vs. 39.0%, respectively). The other short-term clinical outcomes were similar in both groups. The R0 resection rate was 99.0% in the SPS group and 98.7% in the MPS group. The oncological clearance was satisfactory and similar in both groups. The current study concluded that SPS can be performed safely and provide satisfactory oncological outcomes in patients with rectal cancer. However, further studies are required to determine the role of SPS in the long-term clinical and oncological outcomes.

[PMID: 32884224 PMCID: PMC7445872 DOI: 10.3748/wjg.v26.i31.4669] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Revised: 06/21/2020] [Accepted: 07/23/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Single incision plus one port left-side approach (SILS+1/L) totally laparoscopic distal gastrectomy (TLDG) is an emerging technique for the treatment of gastric cancer. Reduced port laparoscopic gastrectomy has a number of potential advantages for patients compared with conventional laparoscopic gastrectomy: relieving postoperative pain, shortening hospital stay and offering a better cosmetic outcome. Nevertheless, there are no previous reports on the use of SILS+1/L TLDG with uncut Roux-en-Y (uncut R-Y) reconstruction.
AIM To investigate the initial feasibility of SILS+1/L TLDG with uncut Roux-en-Y digestive tract reconstruction (uncut R-Y reconstruction) to treat distal gastric cancer.
METHODS A total of 21 patients who underwent SILS+1/L TLDG with uncut R-Y reconstruction for gastric cancer were enrolled. All patients were treated at The Second Hospital of Shandong University. Reconstructions were performed intracorporeally with 60 mm endoscopic linear stapler and 45 mm no-knife stapler. The clinicopathological characteristics, surgical details, postoperative short-term outcomes, postoperative follow-up upper gastrointestinal radiography findings and endoscopy results were analyzed retrospectively.
RESULTS All SILS+1/L operations were performed by SILS+1/L TLDG successfully. The patient population included 13 men and 8 women with a mean age of 48.2 years (ranged from 40 years to 70 years) and median body mass index of 22.8 kg/m2. There were no conversions to open laparotomy, and no other port was placed. The mean operation time was 146 min (ranged 130-180 min), and the estimated mean blood loss was 54 mL (ranged 20-110 mL). The mean duration to flatus and discharge was 2.3 (ranged 1-3.5) and 7.3 (ranged 6-9) d, respectively. The mean number of retrieved lymph nodes was 42 (ranged 30-47). Two patients experienced mild postoperative complications, including surgical site infection (wound at the navel incision) and mild postoperative pancreatic fistula (grade A). Follow-up upper gastrointestinal radiography and endoscopy were carried out at 3 mo postoperatively. No patients experienced moderate or severe food stasis, alkaline gastritis or bile reflux during the follow-up period. No recanalization of the biliopancreatic limb was found.
CONCLUSION SILS+1/L TLDG with uncut R-Y reconstruction could be safely performed as a reduced port surgery.

Abstract
Introduction Single-incision laparoscopic surgery (SILS) has benefits, including less postoperative pain, a shorter incision, and improved cosmesis. However, SILS is technically difficult because of the limited movement. An organ retractor is an instrument that has the potential to overcome these limitations. Presentation of case An 85-year-old woman with hematochezia was referred to our hospital. Emergency endoscopy showed diverticulosis of the entire colon and active bleeding from the ascending colon. Despite endoscopic clipping, the bleeding continued. SILS total colectomy using an organ retractor was performed due to uncontrollable diverticular bleeding. A 3-cm incision was placed in the umbilicus, and three conventional ports were inserted into the single umbilical incision. An organ retractor was used for hepatocolic ligament transection, transection of the ileocolic vessels, and transection of the mesentery of the sigmoid colon. For each transection, the tension was adjusted to provide a good operative view. The patient's postoperative course was uneventful. Conclusion An organ retractor was effective for SILS total colectomy to maintain an adequate operative view, which enabled safe dissection.

A propensity score-matched comparison between learning phases. Surg Endosc 2020; 35:770-778. [PMID: 32055993 DOI: 10.1007/s00464-020-07445-3] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2019] [Accepted: 02/10/2020] [Indexed: 11/26/2022]
Abstract
BACKGROUND Although studies of robotic rectal cancer surgery have demonstrated the effects of learning on operation time, comparisons have failed to demonstrate differences in clinicopathological outcomes between unadjusted learning phases. This study aimed to investigate the learning curve of robotic rectal cancer surgery for clinicopathological outcomes and compare surgical outcomes between adjusted learning phases. Study design We enrolled 506 consecutive patients with rectal adenocarcinoma who underwent robotic resection by a single surgeon between 2007 and 2018. Risk-adjusted cumulative sum (RA-CUSUM) for surgical failure was used to analyze the learning curve. Surgical failure was defined as the occurrence of any of the following: conversion to open surgery, severe complications (Clavien-Dindo grade ≥ 3a), insufficient number of harvested lymph nodes (LNs), or R1 resection. Comparisons between learning phases analyzed by RA-CUSUM were performed before and after propensity score matching. RESULTS In RA-CUSUM analysis, the learning curve was divided into two learning phases: phase 1 (1st-177th cases, n = 177) and phase 2 (178th-506th cases, n = 329). Before matching, patients in phase 2 had deeper tumor invasion and higher rates of positive LNs on pretreatment images and preoperative chemoradiotherapy. After matching, phase 1 (n = 150) and phase 2 (n = 150) patients exhibited similar clinical characteristics. Phase 2 patients had lower rates of surgical failure overall and these components: conversion to open surgery, severe complications, and insufficient harvested LNs. CONCLUSIONS For robotic rectal cancer surgery, surgical outcomes improved after the 177th case. Further studies by other robotic surgeons are required to validate our results.
