Project description:BackgroundSelection of intracorporeal anastomosis (IA) or extracorporeal anastomosis (EA) in laparoscopic right colectomy (LRC) remains controversial. This meta-analysis aimed to evaluate the effectiveness and safety of IA compared with EA in LRC patients.MethodsLiterature was searched systematically for randomized controlled trials (RCTs) that compared IA with EA in LRC patients until May 2021. The eligible studies for risk of bias were assessed using the Cochrane Risk of Bias Tool. Data were extracted and analysed for the following outcomes of interest: operative time, length of incision, nodal harvest, bowel function recovery, postoperative pain, postoperative complications (wound infection, anastomotic leak, ileus, obstruction, reoperation), death at 30 days, duration of hospital stay and 30-day readmission.ResultsFive RCTs, including a total of 559 patients, were eligible for meta-analysis. All of the trials reported adequate random sequence generation and allocation concealment. There were significantly better outcomes in the IA group than in the EA group in time to first flatus (mean difference (MD) -0.71 (95 per cent c.i. -1.12 to -0.31), P = 0.0005), time to first passage of stool (MD -0.53 (95 per cent c.i. -0.69 to -0.37), P < 0.00001), visual analogue scale of pain on postoperative day (POD) 3 (MD -0.76 (95 per cent c.i. -1.23 to -0.28), P = 0.002), POD 4 (MD -0.83 (95 per cent c.i. -1.46 to -0.20), P = 0.01), POD 5 (MD -0.60 (95 per cent c.i. -0.95 to -0.25), P = 0.0007), length of incision (MD -1.52 (95 per cent c.i. -2.30 to -0.74), P = 0.0001) and wound infection (relative risk 0.46 (95 per cent c.i. 0.23 to 0.91), P = 0.02). However, there were no statistically significant differences between the two groups in duration of hospital stay (P = 0.47), operative time (P = 0.07), number of lymph nodes harvested (P = 0.70), anastomotic leak (P = 0.88), postoperative ileus (P = 0.48), bleeding (P = 0.15), bowel obstruction (P = 0.24), reoperation (P = 0.34), readmission within 30 days (P = 0.26), and death (P = 0.70).ConclusionCompared with EA, IA shows a faster recovery of bowel function with fewer wound infections.

Project description:BackgroundThe laparoscopic right hemicolectomy is the standard surgical treatment for right-sided colon cancer. The continuity of the digestive tract is restored through ileocolic anastomosis which can be performed extracorporeally or intracorporeally. The study aimed to compare both anastomotic techniques in laparoscopic right hemicolectomy.Materials and methodsA single-blinded two-armed randomized control trial with 1:1 parallel allocation carried out from 2016 to 2020 in a single center. The follow-up period was 30 days. Compared interventions involved extracorporeal and intracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy. The main outcome of the study was bowel recovery measured as the time to the first stool. Other outcomes involved the time to the first flatus, morbidity, and duration of surgery.ResultsOne hundred and seventeen patients undergoing a laparoscopic right hemicolectomy with curative intent were eligible for the trial. Eight patients refused to participate. One hundred and two patients were analyzed, 52 in the intracorporeal group and 50 in the extracorporeal group. The groups did not differ in terms of cancer stage or body mass index, but did differ in age and sex. Intracorporeal anastomosis was associated with a shorter time to the first stool than extracorporeal, 32.8 h (26.0-43.7) vs. 41.7 (35.9-50.0), p = 0.017. There was no significant difference in the time to the first flatus, 30 h (23.2-42.3) vs. 26.6 h (21.8-37.3), p = 0.165. Similarly, overall complications did not differ (EC 12/50 vs. IC 10/52, p = 0.56). There were no differences in length of surgery, 190 min (150-230) and 190 min (180-220), p = 0.55.ConclusionIntracorporeal ileocolic anastomosis following laparoscopic right hemicolectomy results in slightly faster bowel recovery, with no differences in morbidity and duration of surgery.

Project description:Right colectomy (hemicolectomy) involves the removal of the cecum, the ascending colon, the hepatic flexure, the first one-third of the transverse colon, part of the terminal ileum, and the associated regional fat and lymph nodes, and is the accepted treatment for malignant neoplasms of the right colon.
A minimally invasive approach is commonly used for right colectomy, with studies reporting reduced complications, less blood loss, and hospital stay when compared to an open approach.
However, there remains controversy regarding whether robotic assistance is advantageous for this technique and whether an intracorporeal (ICA) or extracorporeal anastomosis (ECA) is best.
MIRCAST is a prospective, observational, international, multi-center, 4-parallel-cohorts study. Sites or surgeons will select a cohort of the study for which they are qualified. Four cohorts will be the subject of study:
1. Robotic Right Colectomy with ICA
2. Robotic Right Colectomy with ECA
3. Laparoscopic Right Colectomy with ICA
4. Laparoscopic Right Colectomy with ECA
All patient assessments will be done according to the sites standard of care. Parameters routinely recorded during right colectomy surgery will be collected prospectively. Enrolled subjects will undergo assessments at the following intervals: pre-operative, operative, discharge, 30 days, 3 months, 1 year and 2 years post-surgery.

Project description:AimThe COVID-19 pandemic has forced surgeons to adapt their standard procedures. The modifications introduced are designed to favour minimally invasive surgery. The positive results obtained with intracorporeal resection and anastomosis in the right colon and rectum prompt us to adapt these procedures to the left colon. We describe a 'don't touch the bowel' technique and outline the benefits to patients of the use of less surgically aggressive techniques and also to surgeons in terms of the lower emission of aerosols that might transmit the COVID-19 infection.MethodsThis was an observational study of intracorporeal resection and anastomosis in left colectomy. We describe the technical details of intracorporeal resection, end-to-end stapled anastomosis and extraction of the specimen through mini-laparotomy in the ideal location.ResultsWe present preliminary results of 17 patients with left-sided colonic pathologies, 15 neoplasia and two diverticular disease, who underwent four left hemicolectomies, six sigmoidectomies and seven high anterior resections. Median operating time was 186 min (range 120-280). No patient required conversion to extracorporeal laparoscopy or open surgery. Median hospital stay was 4.7 days (range 3-12 days). There was one case of anastomotic leak managed with conservative treatment.ConclusionIntracorporeal resection and end-to-end anastomosis with the possibility of extraction of the specimen by a mini-laparotomy in the ideal location may present benefits and also adapts well to the conditions imposed by the COVID-19 pandemic. Future comparative studies are needed to demonstrate these benefits with respect to extracorporeal anastomosis.

Project description:BackgroundThe impact of method of anastomosis and minimally invasive surgical technique on surgical and clinical outcomes after right hemicolectomy is uncertain. The aim of the MIRCAST study was to compare intracorporeal and extracorporeal anastomosis (ICA and ECA respectively), each using either a laparoscopic approach or robot-assisted surgery during right hemicolectomies for benign or malignant tumours.MethodsThis was an international, multicentre, prospective, observational, monitored, non-randomized, parallel, four-cohort study (laparoscopic ECA; laparoscopic ICA; robot-assisted ECA; robot-assisted ICA). High-volume surgeons (at least 30 minimally invasive right colectomy procedures/year) from 59 hospitals across 12 European countries treated patients over a 3-year interval The primary composite endpoint was 30-day success, defined by two measures of efficacy-absence of surgical wound infection and of any major complication within the first 30 days after surgery. Secondary outcomes were: overall complications, conversion rate, duration of operation, and number of lymph nodes harvested. Propensity score analysis was used for comparison of ICA with ECA, and robot-assisted surgery with laparoscopy.ResultsSome 1320 patients were included in an intention-to-treat analysis (laparoscopic ECA, 555; laparoscopic ICA, 356; robot-assisted ECA, 88; robot-assisted ICA, 321). No differences in the co-primary endpoint at 30 days after surgery were observed between cohorts (7.2 and 7.6 per cent in ECA and ICA groups respectively; 7.8 and 6.6 per cent in laparoscopic and robot-assisted groups). Lower overall complication rates were observed after ICA, specifically less ileus, and nausea and vomiting after robot-assisted procedures.ConclusionNo difference in the composite outcome of surgical wound infections and severe postoperative complications was found between intracorporeal versus extracorporeal anastomosis or laparoscopy versus robot-assisted surgery.

Project description:IntroductionWhile intracorporeal anastomosis (IA) has been widely used in totally laparoscopic right colectomy, its application in laparoscopic segmental left colectomy for splenic flexure cancer remains underexplored, particularly in large-scale studies with long-term outcomes. This research aims to assess the technical feasibility and oncological efficacy of IA in treating colonic splenic flexure carcinoma, drawing insights from both short-term and long-term outcomes of a retrospective cohort.Materials and methodsA retrospective analysis was conducted on 342 patients diagnosed with colonic splenic flexure carcinoma in three Chinese medical centers. These patients underwent laparoscopic segmental left colectomy between December 2014 and December 2019 across three medical institutions. Comprehensive data encompassing demographics, disease features, pathological characteristics, operative details, and both short-term and long-term outcomes were gathered and scrutinized. Using propensity scores, each patient from the IA cohort was paired with a counterpart from the extracorporeal anastomosis (EA) cohort.ResultsIA was performed on 129 patients, while 213 underwent EA. Post-propensity score matching resulted in 129 matched pairs. After matching, many baseline characteristics were balanced. The IA cohort exhibited several advantages, including shorter incision lengths ( P <0.001) and more extensive proximal and distal resection margins ( P =0.003, P <0.001). Additionally, the IA method facilitated a more rapid postoperative recovery as indicated by quicker return of bowel movements (resumption of passing flatus [2.7 (1.0-7.0) days vs. 3.3 (2.0-8.0) days, P <0.001] and defecation [3.7 (1.0-9.0)] days vs. 4.5 (2.0-9.0) days, P <0.001]), faster discharges [6.6 (3.0-15.0) days vs. 8.3 (5.0-20.0) days, P <0.001], and decreased need for rescue analgesics ( P <0.001). The rate of postoperative complications, as rated by the Clavien-Dindo classification, remained consistent across both techniques ( P =0.087). Furthermore, the cosmetic outcome rated by Patient Scar Assessment Questionnaire and Scoring System (PSAQ) was markedly superior in the IA group ( P <0.001). Both approaches demonstrated equivalent 5-year overall (82.7% vs. 82.1%, P =0.419) and disease-free survival (80.9% vs. 78.1%, P =0.476). Subsequent stratification analysis revealed that IA achieved comparable 5-year overall (80.7% vs. 82.0%, P =0.647) and disease-free survival (78.1% vs. 76.4%, P =0.734) in patients with locally advanced colon cancer.ConclusionEmploying IA for laparoscopic segmental left colectomy in cases of splenic flexure carcinoma is not only safe but also offers enhanced cosmetic results and expedited postoperative recovery. Oncologically speaking, IA in left segmental colectomy for splenic flexure carcinoma can yield therapeutic outcomes comparable to those of EA, even in patients with locally advanced colon cancer.
