Robot-assisted versus laparoscopic short- and long-term outcomes in complete mesocolic excision for right-sided colonic cancer: a systematic review and meta-analysis. Tech Coloproctol 2023; 27:171-181. [PMID: 36001164 DOI: 10.1007/s10151-022-02686-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: 12/09/2021] [Accepted: 08/10/2022] [Indexed: 02/07/2023]
Abstract
BACKGROUND Complete mesocolic excision (CME) surgery is increasingly implemented for the resection of right-sided colonic cancer, possibly resulting in improved 5-year overall and disease-free survival compared to non-CME surgery. However, it is not clear what surgical platform should be used. The aim of this study was to compare the following outcomes between robot-assisted and laparoscopic CME-surgery for right-sided colonic cancer: (i) short-term clinical outcomes, (ii) pathological specimen quality, and (iii) long-term oncological outcomes. METHODS Medline, Embase, and Cochrane Database of Systematic Reviews were searched from inception until August 2021. Pooled proportions were calculated by applying the inverse variance method. Heterogeneity was explored by I-square and supplemented by sensitivity- and meta-regression analyses. The risk of bias was evaluated by either MINORS or Cochrane's risk-of-bias tool (RoB 2). RESULTS Fifty-five studies with 5.357 patients (740 robot-assisted and 4617 laparoscopic) were included in the meta-analysis. Overall postoperative morbidity was 17% [95% CI (14-20%)] in the robot-assisted group and 13% [95%CI (12-13%)] in the laparoscopic group. Robot-assisted CME was associated with a shorter hospital stay, lower intraoperative blood loss, a higher amount of harvested lymph nodes, and better 3-year oerall and disease-free survival. MINORS and RoB2 indicated a serious risk of bias across studies included. CONCLUSIONS This review which includes predominantly non-randomized studies suggests a possible advantage of the robot-assisted CME compared with a laparoscopic technique for several short-term outcomes.

Abstract
Various approaches can be used for performing laparoscopic right hemicolectomy for right-sided colon cancer. However, laparoscopic complete mesocolic excision with central vessel ligation using these approaches may sometimes present with difficulties of various factors. This video article presents a laparoscopic extended right hemicolectomy using a superior-to-inferior approach. The superior approach has potential benefits in that it exposes the superior mesenteric vessels and gastrocolic trunk.

Abstract
Background: There is a rapidly growing literature available on right hemicolectomy comparing the short- and long-term outcomes of robotic right colectomy (RRC) to that of laparoscopic right colectomy (LRC). The aim of this meta-analysis is to revise current comparative literature systematically. Methods: A systematic review of comparative studies published between 2000 to 2021 in PubMed, Scopus and Embase was performed. The primary endpoint was postoperative morbidity, mortality and long-term oncological results. Secondary endpoints consist of blood loss, conversion rates, complications, time to first flatus, hospital stay and incisional hernia rate. Results: 25 of 322 studies were considered for data extraction. A total of 16,099 individual patients who underwent RRC (n = 1842) or LRC (n = 14,257) between 2002 and 2020 were identified. Operative time was significantly shorter in the LRC group (LRC 165.31 min ± 43.08 vs. RRC 207.38 min ± 189.13, MD: −42.01 (95% CI: −51.06−32.96), p < 0.001). Blood loss was significantly lower in the RRC group (LRC 63.57 ± 35.21 vs. RRC 53.62 ± 34.02, MD: 10.03 (95% CI: 1.61−18.45), p = 0.02) as well as conversion rate (LRC 1155/11,629 vs. RRC 94/1534, OR: 1.65 (1.28−2.13), p < 0.001) and hospital stay (LRC 6.15 ± 31.77 vs. RRC 5.31 ± 1.65, MD: 0.84 (95% CI: 0.29−1.38), p = 0.003). Oncological long-term results did not differ between both groups. Conclusion: The advantages of robotic colorectal procedures were clearly demonstrated. RRC can be regarded as safe and feasible. Most of the included studies were retrospective with a limited level of evidence. Further randomized trials would be suitable.

Abstract
PURPOSE The concept of complete mesocolic excision (CME) in right-sided colorectal cancer is well known for open and laparoscopic surgery. The aim of this study was to evaluate and compare perioperative and oncological outcomes of reduced port and open surgery for right-sided colorectal cancer. METHODS One hundred forty-one patients received elective surgery for right-sided colonic cancer between January 2015 and December 2019 and were included in a retrospective database. RESULTS We observed longer operation time in the RP-CME group (145 min vs. 119.43 min, p<0.01). Hospital stay (8 days vs. 14 days, p<0.01) and time to first intestinal passage (42 h. vs. 59 h, p<0.01) were significantly shorter in the reduced port group. Postoperative complications were more likely to be observed in the O-CME group (7.2% vs. 14.1%, p=0.28); anastomotic leakage rate was low in both groups (1.8% vs. 2.4%, p=1.00). Specimen scores (score 1= good: 93.8% vs. 91.7%, p=1.00) and average number of retrieved lymph nodes were comparable (24 vs. 23 p=0.69). In O-CME patients, we observed more advanced tumor stages (UICC III: 21.4% vs. 45.9%, p<0.01). CONCLUSION To our knowledge, this is the first study comparing reduced port to open surgery for right-sided colorectal cancer. We could demonstrate that this technique is feasible for oncological right hemicolectomy with observation of shorter hospital stay and lower morbidity rates compared to open surgery. The oncological outcome did not differ in the present study.

Abstract
BACKGROUND In right-sided colon cancer surgery, currently there is a great deal of discussion and debate regarding complete mesocolic excision (CME) versus conventional right hemicolectomy (CRH) on postoperative outcomes and oncological results. Our aim was to perform a systematic review of the short- and long-term outcomes of CME to standardize surgical approach in patients with right-sided colon cancer. METHODS A systematic review was performed examining available data on randomized and non-randomized studies evaluating the role of CME and D3 lymphadenectomy in the treatment of right-sided colon cancer, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards. RESULTS After literature search, 919 studies have been recorded, 110 studies underwent full-text reviews and 30 studies met inclusion criteria. The total number of CME procedures was 5931. Postoperative complications was reported in 28 studies with pooled overall complications of 1.88% for CME surgery. Six studies reported 0% of overall postoperative complications and they demonstrated a low incidence of complications following CME procedure. Anastomotic leak was reported in 27 studies with pooled proportion of 0.92% after CME resections. There were 16 papers reporting overall survival following CME procedure, with a mean of 85% of patients survived at 5 years. Mean 5-year overall survival was 93.05% in stage I patients, 89.76% in stage II patients and 79.65% in stage III patients. Local and distant recurrence were included in 21 studies, reporting tumor recurrence rate of 12.25% following CME. 5-year tumor recurrence was 5.8% in stage I patients, 7.68% in stage II patients and 15.69% in stage III patients. CONCLUSIONS CME does not increase the risk of postoperative complications and significantly improves the long-term oncological impact. Prospective multicentre studies results are needed to verify if CME could be considered standard surgery for right colon cancer.

Abstract
Complete mesocolic excision (CME) is being performed more frequently and has recently become an established oncologic surgical method for right hemicolectomy. Despite its advantages, such as its association with early mobilization, a short hospital stay, early bowel movement, mild postoperative pain, and good cosmesis, CME is technically demanding and carries the risk of severe complications. This study aims to compare the clinical, pathological, and oncological results of open and laparoscopic right hemicolectomy with CME.The data of 76 patients who underwent right hemicolectomy with CME and high vascular ligation were reviewed retrospectively. The patients were divided into 2 groups according to whether the open or laparoscopic technique was used.Thirty-two patients underwent open right hemicolectomy, and 44 patients underwent laparoscopic right hemicolectomy. The 2 groups were similar in age, sex, American Society of Anesthesiologists class, abdominal surgical history, tumor localization, and operation time. No significant differences were found regarding the specimen length, tumor size, harvested lymph nodes, number of metastatic lymph nodes, or tumor grade. According to the Clavien-Dindo classification system, the laparoscopic group had significantly fewer complications than did the open group (11.4% vs 31.2%; P = .04). The open group had a longer postoperative hospital stay than did the laparoscopic hemicolectomy group (9.9 ± 4.7 vs 7.2 ± 3.1 days; P = .002). In addition, the groups were similar with respect to disease-free survival (P = .14) and overall survival (P = .06).The data in this study demonstrated that no differences exist between the open and laparoscopic techniques concerning pathological and oncological results. However, significantly fewer complications and a shorter length of hospital stay were observed in the laparoscopic group than in the open group. Laparoscopic right hemicolectomy with CME and central vascular ligation is a safe and feasible surgical procedure and should be considered the standard technique for right-sided colon cancer.

Abstract
BACKGROUND Complete mesocolic excision with central vessel ligation may be important for accurate staging and improving the prognosis of right-sided colon cancer. Although the procedure is often performed laparoscopically, approaching the middle colic artery (MCA) is technically demanding, especially when complete ligation of arteries at their roots is desired. We standardized our laparoscopic approach by establishing the dissection boundary along the superior mesenteric artery to achieve D3 lymphadenectomy in the region of the MCA. The aim of the present study was to evaluate, on the basis of perioperative and short-term oncologic outcomes, the feasibility and safety of our technique METHODS: We conducted a retrospective study on consecutive patients with cancer located at the ascending colon and transverse colon who had laparoscopic right hemicolectomy requiring ligation of the MCA. RESULTS There were 41 patients (22 males, median age 71 years [range 49-86] years). The median operation time was 285 min, and blood loss volume was 40 mL. Conversion to open surgery was required in 1 case. Complications that were Clavien-Dindo grade III or above occurred in 3 patients (7.3%). There was no anastomotic leakage. The median number of lymph nodes harvested was 46. CONCLUSIONS Our technique was shown to be a safe, feasible, and useful strategy for performance of right hemicolectomy requiring ligation of the MCA in cases of colon cancer. The technique facilitates maximal lymph node dissection. Having obtained favorable outcomes, we look forward to investigation into long-term outcomes.

Abstract
BACKGROUND The optimal lymph node dissection with central vascular ligation is an important part for oncological outcomes after laparoscopic right-sided colon cancer surgery. Few studies have examined the clinical value of indocyanine green fluorescence imaging-guided D3 dissection for right-sided colon cancer. OBJECTIVES We assessed the clinical value of indocyanine green fluorescence imaging-guided laparoscopic surgery in improving the radicality of lymph node dissection for right-sided colon cancer by comparing the outcomes of conventional laparoscopic surgery. DESIGN The data were retrospectively reviewed and analyzed. SETTING This study was conducted at a single university hospital. PATIENTS A 1:2 matched case-control study included 25 patients undergoing fluorescence imaging-guided laparoscopic surgery and 50 patients undergoing conventional laparoscopic surgery for clinical T3 or T4 right-sided colon cancer between June 2016 and December 2017. MAIN OUTCOME MEASURES The extent of D3 dissection and pathological results (tumor stage, lymph node yield, and number of metastatic lymph nodes) were analyzed. RESULTS The 2 groups were similar in baseline characteristics. The numbers of harvested pericolic and intermediate lymph nodes were not different between the 2 groups. The numbers of central lymph nodes (14 vs 7, p < 0.001) and total harvested lymph nodes (39 vs 30, p = 0.003) were significantly higher in the fluorescence group than in the conventional group. In the multivariate analysis, the use of indocyanine green fluorescence imaging was an independently related factor for the retrieval of higher numbers of overall and central lymph nodes. The number of metastatic lymph nodes was not significantly different between the 2 groups. LIMITATIONS The results of this study were limited by its small patient numbers and retrospective nature. CONCLUSIONS Real-time indocyanine green fluorescence imaging of lymph nodes may improve the performance of more radical D3 lymph node dissection during laparoscopic right hemicolectomy for advanced right-sided colon cancer.

El número de ganglios linfáticos pericólicos e intermedios recolectados no fue diferente entre los dos grupos. El número de ganglios linfáticos centrales (14 vs 7, p < 0.001) y el total de ganglios linfáticos recolectados (39 vs 30, p = 0.003) fueron significativamente mayores en el grupo de fluorescencia que en el grupo convencional. En el análisis multivariante, el uso de imágenes de fluorescencia verde indocianina fue un factor independiente relacionado para la recuperación de un mayor número de ganglios linfáticos centrales y globales. El número de ganglios linfáticos metastásicos no fue significativamente diferente entre los dos grupos.Los resultados de este estudio fueron limitados por su pequeño número de pacientes y su naturaleza retrospectiva.Las imágenes de fluorescencia verde indocianina en tiempo real de los ganglios linfáticos pueden mejorar el rendimiento de la disección más radical de los ganglios linfáticos D3 durante la hemicolectomía derecha laparoscópica para el cáncer de colon avanzado del lado derecho.

Abstract
BACKGROUND It remains unclear whether extended lymphadenectomy provides oncological advantages in colorectal cancer. This multicentre RCT aimed to address this issue. METHODS Patients with resectable primary colonic cancer were enrolled in four hospitals registered in the COLD trial, and randomized to D2 or D3 dissection in a 1 : 1 ratio. Data were analysed to assess the safety of D3 dissection. RESULTS The study included the first 100 patients randomized in this ongoing trial. Ninety-nine patients were included in the intention-to-treat (ITT) analysis (43 D2, 56 D3). Ninety-two patients received the allocated treatment and were included in the per-protocol (PP) analysis: 39 of 43 in the D2 group and 53 of 56 in the D3 group. There were no deaths. The 30-day postoperative morbidity rate was 47 per cent in the D2 group and 48 per cent in the D3 group, with a risk ratio of 1·04 (95 per cent c.i. 0·68 to 1·58) (P = 0·867). There were two anastomotic leaks (5 per cent) in the D2 group and none in the D3 group. Postoperative recovery, complication and readmission rates did not differ between the groups in ITT and PP analyses. Mean lymph node yield was 26·6 and 27·8 in D2 and D3 procedures respectively. Good quality of complete mesocolic excision was more frequently noted in the D3 group (P = 0·048). Three patients in the D3 group (5 per cent) had metastases in D3 lymph nodes. D3 was never the only affected level of lymph nodes. N-positive status was more common in the D3 group (46 per cent versus 26 per cent in D2), with a risk ratio of 1·81 (95 per cent c.i. 1·01 to 3·24) (P = 0·044). CONCLUSION D3 lymph node dissection is feasible and may be associated with better N staging. Registration number: NCT03009227 ( http://www.clinicaltrials.gov).

Abstract
BACKGROUND Colectomies performed according to complete mesocolic excision (CME) principles have demonstrated an improvement in the quality of surgical specimen and a potential improvement of long-term results. Laparoscopic CME right hemicolectomy is considered a demanding procedure and adopted in few centers from the West. The main purpose of this paper is to present a video showing our technique for laparoscopic CME right hemicolectomy and to analyze our short-term results to prove its safety. METHODS Data from 38 patients operated on at the Division of General and Hepatobiliary Surgery, University of Verona Hospital Trust, between September 2014 and February 2017, were included in the study. RESULTS In the present series, 37% of patients were ≥75 years old, 32% of patients were ASA class 3, 46% of patients had ≥2 comorbidities, 30% of patients had BMI >28 and 17% of patients had ≥2 previous abdominal surgeries. Despite these unfavorable clinic characteristics, no mortality was observed, Clavien-Dindo ≥3 complications occurred in 13.1% and redo surgery in 5.3%. Good quality specimens were obtained with a mean (SD) length of 34.5±7.5 cm, a proximal margin of 16.8±9.2 cm and a distal margin of 14.3±6.4 cm. The mean (SD) number of harvested lymph nodes was 24.3 (8.3). CONCLUSIONS When implemented in a Western center, laparoscopic CME right hemicolectomy is feasible and safe and allows obtaining good quality specimens.

Abstract
Background This study aimed to investigate the clinical outcome of complete mesocolic excision (CME) with a caudal-to-cranial medial approach in the treatment of right colon cancer. Methods The clinical data of 172 patients who underwent laparoscopic CME for right colon cancer and were admitted to the First Affiliated Hospital of Nanjing Medical University from January 2010 to April 2015 were retrospectively analyzed. The 3-year disease-free survival (DFS) and overall survival (OS) in relation to gender, age, history of abdominal surgery, tumor size, complications, and tumor–node–metastasis (TNM) classification were analyzed using the Kaplan–Meier survival curves. Results A total of 172 patients with 94 males and 78 females were included. The average surgical time was 113.5 ± 34.4 min, blood loss was 74.2 ± 28.1 mL, and the number of lymph nodes retrieved was 23.3 ± 9.2. No readmission or death occurred within 30 days after surgery. Postoperative complications occurred in 16.3% of the patients, which included wound infection (3 patients), chylous fistula (22 patients), anastomotic leakage (1 patient), anastomotic bleeding (1 patient), and lung infection (1 patient). The 3-year DFS and OS were 81.7 and 89.1%, respectively. The rate of DFS and OS was significantly higher in stages I and II compared with that in stage III (P < 0.05), and in stages IIIA and IIIB compared with that in stage IIIC (P < 0.05). Conclusions Laparoscopic CME with a caudal-to-cranial medial approach in the treatment of right colon cancer had good short-term efficacy and satisfactory oncological outcome.

Abstract
Background Although conventional laparoscopic and hand-assisted laparoscopic surgery for colorectal cancer is widely used today, there remain many technical challenges especially for right colon cancer in obese patients. Herein, we develop a novel hand-assisted laparoscopic surgery (HALS) with complete mesocolic excision (CME), D3 lymphadenectomy, and a total “no-touch” isolation technique (HALS-CME) in right hemicolectomy to overcome these issues. According to previous clinic practice, this novel procedure is not only feasible and safe but has several technical merits. However, the feasibility, short-term minimally invasive virtues, long-term oncological superiority, and potential total “no-touch” isolation technique benefits of HALS-CME should be confirmed by a prospective randomized controlled trial. Methods/design This is a single-center, open-label, noninferiority, randomized controlled trial. Eligible participants will be randomly assigned to the HALS-CME group or to the laparoscopic surgery with CME, D3 lymphadenectomy, and total “no-touch” isolation technique (LAP-CME) group, or to conventional laparoscopic surgery with CME and D3 lymphadenectomy (cLAP) group at a 1:1:1 ratio using a centralized randomization list. Primary endpoints include safety, efficacy, and being oncologically clear, and 3-year disease-free, progression-free, and overall survival. Second endpoints include operative outcomes (operation time, blood loss, and incision length), pathologic evaluation (grading the plane of surgery, length of proximal and distal resection margins, distance between the tumor and the central arterial high tie, distance between the nearest bowel wall and the same high tie, area of mesentery resected, width of the chain of lymph-adipose tissue, length of the central lymph-adipose chain, number of harvested lymph nodes), and postoperative outcomes (pain intensity, postoperative inflammatory and immune responses, postoperative recovery). Discussion This trial will provide valuable clinical evidence for the feasibility, safety, and potential total “no-touch” isolation technique benefits of HALS-CME for right hemicolectomy. The hypothesis is that HALS-CME is feasible for the radical D3 resection of right colon cancer and offers short-term safety and long-term oncological superiority compared with conventional laparoscopic surgery.

Abstract
INTRODUCTION Multidimensional comparison between open, laparoscopy, and robotic surgery in the management of right-sided colon cancer are lacking. The aim of this study was to compare the early perioperative results and oncologic outcomes among the 3 different methods. PATIENTS AND METHODS Between June 2007 and 2011, a total of 96 patients who underwent right hemicolectomy in a single institution were classified into the open surgery (OS; n=33), the laparoscopy surgery (LS; n=43), and the robot surgery (RS; n=20) groups. Perioperative and oncologic outcomes were compared among the 3 groups. RESULTS Patient demographics were comparable. Operation time was significantly longer in the RS and LS than the OS (P<0.001). There was 1 OS conversion in LS. There was no difference of total retrieved lymph node numbers among the 3 groups. Postoperative recovery was faster and hospital stay was shorter in RS than OS. However, there was no difference between LS and RS. After the median 40 months' follow-up, 5-year disease-free survival was similar among the OS, LS, and RS (87.7%, 84%, and 89.5%, respectively). Total charge and total patient charge were significantly higher in RS than the others. CONCLUSIONS Our comparative study demonstrates that the RS have better short-term outcomes in reducing hospital stay compared with the OS, but similar to the LS. Although the oncologic outcomes are similar, the benefit of RS in right hemicolectomy is unclear considering a high cost of RS.

Abstract
Purpose To demonstrate the feasibility, safety, and technical strategies of hand-assisted laparoscopic complete mesocolic excision (HAL-CME) and to compare oncological outcomes between HAL-CME and the open approach (O-CME) for right colon cancers. Methods Patients who were scheduled to undergo a right hemicolectomy were divided into HAL-CME and O-CME groups. Measured outcomes included demographic variables, perioperative parameters, and follow-up data. Demographic variables included age, sex distribution, body mass index (BMI), American Society of Anesthesiologists (ASA) physical status classification, previous abdominal surgery, tumor localization, and potential comorbidities. Perioperative parameters included incision length, operative time, blood loss, conversion rate, postoperative pain score, postoperative first passage of flatus, duration of hospital stay, total cost, number of lymph nodes retrieved, TNM classification, and postoperative complications. Follow-up data included follow-up time, use of chemotherapy, local recurrence rate, distant metastasis rate, and short-term survival rate. Results In total, 150 patients (HAL-CME, 78; O-CME, 72) were included. The groups were similar in age, sex distribution, BMI, ASA classification, history of previous abdominal surgeries, tumor localization, and potential comorbidities. Patients in the HAL-CME group had shorter incision lengths, longer operative times, less operative blood loss, lower pain scores, earlier first passage of flatus, shorter hospital stay, higher total costs, similar numbers of lymph nodes retrieved, similar TNM classifications, and a comparable incidence of postoperative complications. The 2 groups were also similar in local recurrence rate, distant metastasis rate, and short-term survival rate. Conclusion The results demonstrate that the HAL-CME procedure is a safe, valid, and feasible surgical method for right hemicolon cancers.

Abstract
PURPOSE Surgeons tend to view the robotic right colectomy (RRC) as an ideal beginning procedure to gain proficiency in robotic general and colorectal surgery. Nevertheless, oncological RRC, especially if performed with intracorporeal ileocolic anastomosis confectioning, cannot be considered a technically easier procedure. The aim of this study was to assess the learning curve of the RRC performed for oncological purposes and to evaluate its safety and efficacy investigating the perioperative and pathology outcomes in the different learning phases. METHODS Data on a consecutive series of 108 patients undergoing RRC with intracorporeal anastomosis between June 2011 and September 2015 at our institution were prospectively collected to evaluate surgical and short-term oncological outcomes. CUSUM (Cumulative Sum) and Risk-Adjusted (RA) CUSUM analysis were performed in order to perform a multidimensional assessment of the learning curve for the RRC surgical procedure. Intraoperative, postoperative and pathological outcomes were compared among the learning curve phases. RESULTS Based on the CUSUM and RA-CUSUM analyses, the learning curve for RRC could be divided into 3 different phases: phase 1, the initial learning period (1st-44th case); phase 2, the consolidation period (45th-90th case); and phase 3, the mastery period (91th-108th case). Operation time, conversion to open surgery rate and the number of harvested lymph nodes significantly improve through the three learning phases. CONCLUSIONS The learning curve for oncological RRC with intracorporeal anastomosis is composed of 3 phases. Our data indicate that the performance of RRC is safe from an oncological point of view in all of the three phases of the learning curve. However, the technical skills necessary to significantly reduce operative time, conversion to open surgery rate and to significantly improve the number of harvested lymph nodes were achieved after 44 procedures. These data suggest that it might be prudent to start the RRC learning curve by treating only benign diseases and to reserve the performance of oncological resection to when at least the initial learning phase has been completed.

Abstract
On the same principle than total mesorectal excision in rectal cancer, the effect of complete mesocolic excision on short and long-term outcomes is actually evaluated for colonic adenocarcinoma. This method, usually performed for left colectomy, offers a surgical specimen of higher quality, with a larger number of lymph nodes harvested. For right colectomy, surgical specifications make it less common complete mesocolic excision and conventional surgery offer comparable outcomes, as regards to postoperative morbidity and mortality rates. No differences are identified between laparoscopic and open surgery. On oncologic outcomes, only two studies report a higher free-disease survival after complete mesocolic excision. Then, there is evidence that complete mesocolic excision offers a higher rate of specimen with extensive lymph node resection, without increased morbidity rate. However, there is limited evidence that it leads to improve long-term oncological outcomes.

Abstract
BACKGROUND Complete mesocolic excision (CME) for colonic cancer offers a surgical specimen of higher quality, with higher number of lymph nodes compared to conventional colectomy. However, evidence on oncological outcomes is limited. The aim of the present study is to review recent literature and provide more information regarding the effect of CME colectomy on short- and long-term outcomes. METHOD PubMed and MEDLINE databases were searched, and articles in English reporting data on CME were reviewed. Intraoperative events; postoperative morbidity and mortality; histopathological characteristics, including macroscopic assessment, number, and status of retrieved lymph nodes; and oncological outcomes were the end-points. RESULTS Thirty-two studies were analyzed. As regards the macroscopic assessment, a larger specimen (p = 0.02) that contains a higher number of lymph nodes (p < 0.00001) is acquired after CME. Two studies report a higher disease-free survival, in stage I and II and particularly in stage III disease after CME. CME by laparoscopy offers comparable outcomes, as regards intraoperative blood loss and immediate postoperative morbidity and mortality rates. Specimen quality is similar after either approach, for cancers located at the right and left colon, but not at the transverse colon. CONCLUSION There is strong evidence that CME offers a longer central pedicle that contains more lymph nodes than conventional surgery for colon cancer. CME represents the surgical background for the maximum lymph node harvest, an important quality marker for the surgical outcome. However, and according to present data, there is limited evidence that colectomy in terms of CME leads to improved long-term oncological outcomes.

Abstract
Single-incision laparoscopic surgery is cosmetically beneficial, but technically challenging. In this study, the learning curve (LC) for single-incision laparoscopic right hemicolectomy (SILRC), incorporating complete mesocolic excision to resect right-sided colon cancer, was investigated through multidimensional techniques. Between December 2009 and May 2015, 64 patients each underwent SILRC of right-sided colon cancer at Severance Hospital, performed in all instances by the same surgeon. Moving average and cumulative sum control chart (CUSUM) were used for LC analyses retrospectively. Surgical failure was defined as conversion to conventional laparoscopic surgery, postsurgical morbidity within 30 days, harvested lymph node count <12, or local tumor recurrence. Both moving average and CUSUM graphics of operative time registered nadirs at the 24th patient, with slight ascent thereafter, reaching a plateau at the 40th patient. The CUSUM for surgical success peaked at the 23rd patient. Operative time for 23 patients in phase 1 (1-23) and for 41 patients in phase 2 (24-64) of the LC did not differ significantly. By comparison, significant differences in patients of phase 2 included larger tumor size, higher harvested lymph node counts, longer proximal resection margins, and more advanced disease. As indicated by multidimensional statistical analyses, the LC for SILRC of right-sided colon cancer was 23 patients. In terms of operative time and surgical success, SILRC is feasible for surgeons experienced in LS, but may prove more challenging for novices, given the fundamental technical difficulties of this procedure.

Abstract
Classic colon cancer surgery refers to a wide resection of the tumor-bearing segment and the lymphatics draining along the named artery. The concept of TME has been applied to colon cancer and complete mesocolic excision (CME) in conjuction with central vascular ligation (CVL) has been introduced as the surgical treatment for colon cancer. Here, we discuss appropriate CME procedure with regard to the oncologic backgrounds, essential components, applied anatomy, laparoscopic technique, short-term, and oncologic outcomes. The introduction of CME has improved oncologic outcomes greatly in patients with colon cancer. The improved outcomes with CME can be attributed to underlying sound oncologic principles such as dissection through the proper plane of mesocolic excision, central vascular ligation, and sufficient length of proximal and distal margins. Thereby, CME technique can achieve en bloc removal of the diseased lesion with the increased amount of the colonic mesentery even though the length of for both bowel and mesentery resection remains a matter of debate. CME is a technically demanding operation thus, comprehensive understanding of the applied vascular anatomy is essential for successful CME. Favorable outcomes of open CME have been replicated with a laparoscopic approach. In future perspective, incorporating a structured education program on minimally invasive (laparoscopy or robot) CME would be beneficial.

Abstract
PURPOSE Recent interest in complete mesocolic excision (CME) with central vascular ligation (CVL) or extended (D3) lymphadenectomy (EL) for curative resection of colon cancer has been driven by published series from experienced practitioners showing excellent survival outcomes and low recurrence rates. In this article, we attempt to clarify the role of CME or EL in modern colorectal surgery. METHODS A narrative review of the evidence for CME and EL in the curative treatment of colon cancer. RESULTS The principal of CME surgery, similar to total mesorectal excision (TME) for rectal cancer, is the removal of all lymphatic, vascular, and neural tissue in the drainage area of the tumour in a complete mesocolic envelope with intact mesentery, peritoneum and encasing fascia. Extended (D3) lymphadenectomy (EL) is based on similar principles. Sound anatomical and oncological arguments are made to support the principles of removing the tumor contained within an intact mesocolic facial envelope together with an extended lymph node harvest. Excellent oncological outcomes with minimal morbidity and mortality have been reported. This has led to calls for the standardisation of surgery for colon cancer using CME. However, there is conflicting evidence regarding the prognostic benefit of greater lymph node harvests and the evidence for an oncological benefit of CME is limited by methodology flaws and several potential confounding factors. CONCLUSIONS Although there is a reasonable anatomical and oncological basis for these techniques, there are no randomised controlled trials from which to draw confident conclusions and there is insufficient consistent high quality evidence to recommend widespread adoption of CME.

Abstract
Minimally invasive surgery has gained worldwide acceptance in the treatment of colonic cancer in the last decades, thanks to its well-known advantages in short-term outcomes. Nevertheless, the penetrance of minimally invasive colorectal surgery still remains low. Few studies and metanalysis, to date, have analyzed the results of robotic versus laparoscopic colorectal surgery, often with conflicting conclusions. The robotic platform, thanks to its technological features, may potentially overcome the limitation of standard laparoscopy, especially when performing a complete mesocolic excision resection and an intracorporeal anastomosis. Robotic surgery could also shorten the learning curve of young novice surgeons, provided that strict protocols of structured training are applied. This paper is an update on the current available outcomes of robotic vs laparoscopic surgery in right colectomy.

Abstract
Aim of the study is to comprehensively review the latest trends in laparoscopic complete mesocolic excision (CME) with central vascular ligation (CVL) for the multimodal management of right colon cancer. Historical and up-to-date anatomo-embryological concepts are analyzed in detail, focusing on the latest studies of the mesenteric organ, its dissection by mesofascial and retrofascial cleavage planes, and questioning the need for a new terminology in colonic resections. The rationale behind Laparoscopic CME with CVL is thoroughly investigated and explained. Attention is paid to the current surgical techniques and the quality of the surgical specimen, yielded through mesocolic, intramesocolic and muscularis propria plane of surgery. We evaluate the impact on long term oncologic outcome in terms of local recurrence, overall and disease-free survival, according to the plane of resection achieved. Conclusions are drawn on the basis of the available evidence, which suggests a pivotal role of laparoscopic CME with CVL in the multimodal management of right sided colonic cancer: performed in the right mesocolic plane of resection, laparoscopic CME with CVL demonstrates better oncologic results when compared to standard non-mesocolic planes of surgery, with all the advantages of laparoscopic techniques, both in faster recovery and better immunological response. The importance of minimally invasive meso-resectional surgery is thus stressed and highlighted as the new frontier for a modern laparoscopic total right mesocolectomy.

Abstract
BACKGROUND: Despite the drive toward centralization of surgery in high-volume centers, the majority of colectomies are still performed by low- or medium-volume surgeons. MATERIALS AND METHODS: A modification of the technique of laparoscopic right colectomy (LRC) originally described by Young-Fadok and Nelson was developed. The key points of that technique were maintained, but a different port-site layout and a counterclockwise approach were adopted, to warrant better trocar triangulation, to reduce the need of right colon manipulation and to avoid dissection along false planes. This modified technique was applied in 82 patients by 16 surgeons with no previous experience in LRC. RESULTS: Average operative time was 125 ± 35 min. Conversion occurred in 10 cases (12.2%). Grade III postoperative complications occurred in 3 patients (3.6%). No postoperative mortality was observed. Average number of lymph nodes retrieved was 19 ± 6. Average length of stay was 7 ± 4 days. CONCLUSION: Providing low-volume surgeons with simplified and easy-to-learn surgical techniques could improve outcomes and lead to an increased use of laparoscopy.

Abstract
PURPOSE To evaluate the pathologic, short-term and oncologic outcomes of laparoscopic and open complete mesocolic excision (CME) and central ligation for right-sided colon cancer. METHODS All patients (n = 215) underwent elective CME either by open surgery (n = 99) or laparoscopy (n = 116). RESULTS Mean number of retrieved lymph nodes (31 vs. 27, p = 0.012) was greater in the open CME group. Between the open and laparoscopic CME groups, there were no differences of length of the specimen (44.3 cm and 43.2 cm), ileum (14 cm and 13.3 cm), or colon (30.3 cm and 29.8 cm), respectively. Proximal and distal margins were similar. Mean operative time was similar between the open and laparoscopic CME groups (175 min vs. 178 min). The rate of 30-day postoperative complications (36.4% vs. 23.3%, p = 0.036) was higher in the open CME group. There were no differences in 3-year overall survival rates (86.9% vs. 95.5% in stage II disease and 70.2% vs. 90.7% in stage III disease) or recurrence-free survival rates (84.5% vs. 84.8% in stage II disease and 64.2% vs. 68.9% in stage III disease) between the open and laparoscopic CME groups. CONCLUSIONS Pathologic (specimen lengths, resection margin lengths, number of lymph nodes, and R0 resection) and oncologic outcomes of the laparoscopic CME group were comparable. Moreover, laparoscopic CME conferred short-term benefits in terms of lower rates of postoperative complications, reduced time to soft diet, and reduced length of hospital stay. Based on these results, laparoscopic CME can be considered as a routine elective approach for right-sided colon cancer.

Abstract
INTRODUCTION The concept of complete mesocolic excision (CME) with central vascular ligation (CVL) for treatment of right colon cancer evolved over last one decade. It decreases local recurrences and improves the survival rates. We describe our novel technique which involves first posterior sharp dissection between planes of parietal and visceral fascia of mesocolon followed by ligation of ileocolic, right colic and middle colic pedicles at their origin. We highlight the technical variations with various techniques and advantages over conventional medial to lateral approach in current study. AIM The outcomes were measured in terms of technical feasibility, short-term outcomes and pathological radicality of current laparoscopic technique (IRETA) for CME with CVL. MATERIALS AND METHODS Two hundred twelve patients (163 males) who underwent laparoscopic CME for right colon cancer over the period of January 2009 to December 2013 were analysed via prospectively maintained database. RESULTS 97.16 % of patients (n = 206) underwent laparoscopic CME while six patients required open conversion. Mean operative time was 142 ± 28.4 min with median hospital stay of 5 days (range 4-11). The median count of lymph node harvested were 24 (range 10-42). The complete mesocolic excision plane was achieved in 93.8 % patients. 84.4 % (n = 179) of our patients were having (T3, N+) disease on pathological examination. The overall morbidity (<30 days) was 9.9 %. CONCLUSION Laparoscopic initial retrocolic endoscopic tunnel approach (IRETA) for CME with CVL in right colonic cancers is safe, simpler and feasible laparoscopic approach with minimal complications. Creation of retro colic tunnel is key highlight of IRETA approach. This approach becomes especially useful in patients with late presentations where complete mesocolic excision remains essential to enhance oncological radicality as per evidence available.

Abstract
BACKGROUND Laparoscopic colectomy has become accepted for resection of colon cancer, and laparoscopic complete mesocolic excision (CME) has proved feasible and safe. We have evaluated the safety, efficacy, and feasibility of laparoscopic CME via reduced port surgery (RPS) in patients with colon cancer. METHODS We prospectively assessed 17 consecutive patients with colon cancer undergoing laparoscopic CME via RPS between February 2012 and January 2014. Video recordings were used to assess the quality of the surgery, including CME completion. We also assessed operative data, complications, pathological findings, visual analog scale (VAS), cosmesis, and the hospital length of stay. RESULTS All patients underwent en bloc resection of mesocolon with CME completion. The median surgical duration and blood loss were 298 min and 41 ml, respectively. No intraoperative complications occurred in any patient. The median number of lymph nodes retrieved was 20, with lymph node metastasis identified in eight patients. The mean VAS scores for postoperative days 1, 3, and 7 were 3.2, 1.5, and 0, respectively. All patients were satisfied with their cosmesis. The median postoperative hospital stay was 11 days. CONCLUSIONS Laparoscopic CME via RPS for colon cancer is a safe and feasible surgical procedure with cosmetic advantages.

Abstract
Although total mesorectal excision has now become the ‘gold standard' for the surgical management of rectal cancer, this is not so for colon cancer. Recent data, provided by Hohenberger and West et al. and others, have demonstrated excellent oncological outcomes when mesenterectomy is extensive (as is implicit in the concept of a ‘high tie') and the mesenteric package not violated. Such studies highlight the importance of understanding the basics of the mesenteric organ (including the small intestinal mesentery, mesocolon, mesosigmoid and mesorectum) and of abiding to principles of planar surgery. In this review, we first offer classic descriptions of the mesocolon and then detail contemporary thinking. In so doing, we provide an anatomical basis for safe and effective complete mesocolic excision (CME) in the management of colon cancer. Finally we list opportunities associated with the new anatomical paradigm, demonstrating benefits across multiple disciplines. Perhaps most importantly, we feel that a crystallized view of mesenteric anatomy will overcome factors that have hindered the general uptake of CME.
