RESUMO

BACKGROUND: In this analysis, we aimed to systematically compare the procedural and post-operative complications (POC) associated with laparoscopic versus open abdominal surgery for right-sided colonic cancer resection. METHODS: We searched MEDLINE, http://www.ClinicalTrials.gov, EMBASE, Web of Science, Cochrane Central, and Google scholar for English studies comparing the POC in patients who underwent laparoscopic versus open surgery (OS) for right colonic cancer. Data were assessed by the Cochrane-based RevMan 5.4 software (The Cochrane Community, London, UK). Mean difference (MD) with 95% confidence intervals (CIs) were used to represent the results for continuous variables, whereas risk ratios (RR) with 95% CIs were used for dichotomous data. RESULTS: Twenty-six studies involving a total number of 3410 participants with right colonic carcinoma were included in this analysis. One thousand five hundred and fifteen participants were assigned to undergo invasive laparoscopic surgery whereas 1895 participants were assigned to the open abdominal surgery. Our results showed that the open resection was associated with a shorter length of surgery (MD: 48.63, 95% CI: 30.15-67.12; P = .00001) whereas laparoscopic intervention was associated with a shorter hospital stay [MD (-3.09), 95% CI [-5.82 to (-0.37)]; P = .03]. In addition, POC such as anastomotic leak (RR: 0.96, 95% CI: 0.60-1.55; P = .88), abdominal abscess (RR: 1.13, 95% CI: 0.52-2.49; P = .75), pulmonary embolism (RR: 0.40, 95% CI: 0.09-1.69; P = .21) and deep vein thrombosis (RR: 0.94, 95% CI: 0.39-2.28; P = .89) were not significantly different. Paralytic ileus (RR: 0.87, 95% CI: 0.67-1.11; P = .26), intra-abdominal infection (RR: 0.82, 95% CI: 0.15-4.48; P = .82), pulmonary complications (RR: 0.83, 95% CI: 0.57-1.20; P = .32), cardiac complications (RR: 0.73, 95% CI: 0.42-1.27; P = .27) and urological complications (RR: 0.83, 95% CI: 0.52-1.33; P = .44) were also similarly manifested. Our analysis also showed 30-day re-admission and re-operation, and mortality to be similar between laparoscopic versus OS for right colonic carcinoma resection. However, surgical wound infection (RR: 0.65, 95% CI: 0.50-0.86; P = .002) was significantly higher with the OS. CONCLUSIONS: In conclusion, laparoscopic surgery was almost comparable to OS in terms of post-operative outcomes for right-sided colonic cancer resection and was not associated with higher unwanted outcomes. Therefore, laparoscopic intervention should be considered as safe as the open abdominal surgery for right-sided colonic cancer resection, with a decreased hospital stay.

RESUMO

Introduction: The laparoscopic approach to right colectomy is gradually gaining a leading role in the surgical treatment of right colonic diseases. However, not all aspects of the procedure are standardized and the method of reconstruction of the digestive tract is still under debate. The present study critically evaluates the extracorporeal (EA) and intracorporeal (IA) techniques used for creation of the ileocolic anastomosis during a laparoscopic right colectomy. Material and Method: The EA and IA anastomotic techniques are described in detail. The peri operative data of a cohort of consecutive patients operated by our surgical team was retrospectively recorded and analyzed regarding type of anastomosis, the path for transition from EA to IA and the incidence of postoperative complications. Furthermore, an analysis of randomized clinical trials, reviews and meta-analyses that provided a comparative evaluation of EA versus IA was performed to provide a more in-depth integration of our own data into the literature. Results: EA was used at the beginning of our experience but was later replaced by IA which became the favorite anastomotic technique. There was no anastomotic fistula recorded in the EA or IA groups but in our cohort IA was unexpectedly associated with higher incidence of peritoneal drainage, prolonged ileus, surgical site infections, anastomotic bleeding and chyloperitoneum. However, IA allows better visualization of the ileal and colonic stumps, avoids twisting of the anastomosis, prevents extraction-related tearing of the mesocolon and reduces the risk of post operative hernia. Data from the literature also shows that IA is generally associated with earlier postoperative return of bowel function, less morbidity and less postoperative pain. Conclusions: Based on this study and the data currently present in the literature it can not be concluded that IA should be considered as the standard of care for laparoscopic right colectomy. The decision for an EA or IA anastomosis ultimately belongs to the surgeon and is influenced by his surgical skill and experience. The results of ongoing randomized controlled trials on large group of patients may bring more clarity on this issue in the future.

RESUMO

BACKGROUND: Cancer patients are at increased risk of novel coronavirus disease 2019 (COVID-19). Currently, surgeries for cancer patients with COVID-19 are generally suggested to be properly delayed. CASE PRESENTATION: We presented a 69-year-old Chinese female colon cancer patient with COVID-19, the first case accepted the surgical treatment during the pandemic in China. The patient developed a fever on January 28, 2020. After treatments with Ceftriaxone and Abidol, her fever was not moderated yet. A repeat chest computed tomography (CT) scan showed significantly exacerbated infectious lesions with a positive result for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid. An abdomen CT scan indicated the tumor of ascending colon with local wrapped changes. She was diagnosed with 'Severe novel coronavirus pneumonia' and 'Incomplete bowel obstruction: Colon cancer?'. After actively anti-inflammatory and anti-viral therapies, a right colectomy with lymph node dissection was performed on March 11, followed by a pathological examination. The patient successfully recovered from COVID-19 pneumonia and incomplete bowel obstruction after surgery without any postoperative related complications and was discharged on the 9th day after operation. Significant degeneration, necrosis and slough of focal intestinal and colonic mucosal epithelial cells were observed under microscope. No surgeons, nurses or anesthetists in our team were infected with SARS-CoV-2. CONCLUSIONS: It is meaningful and imperative to share our experience of protecting health care personnels from SARS-CoV-2 infection and providing references for optimizing treatment of cancer patients, at least for the operative intervention with absolute necessity or surgical emergency, during the outbreak of COVID-19.

RESUMO

BACKGROUND: Enhanced recovery after surgery (ERAS) protocols are widely utilized for elective colorectal surgery to improve outcomes and decrease costs, but few studies have evaluated the impact of ERAS protocols on cost with respect to anatomic site of resection. This study evaluated the impact of ERAS protocol on elective colon resections by site and longitudinal impact over time. METHODS: A single-center retrospective cohort study of 598 consecutive patients undergoing elective colorectal resection before and after implementation of ERAS protocol from 2013 to 2017 was performed. The primary outcomes were length of stay (LOS) and cost. Comparative and multivariate inferential statistics were used to assess additional outcomes. RESULTS: A total of 598 patients (100 pre-ERAS vs 498 post-ERAS) were evaluated with an overall median LOS of 4 days for right and left colectomies and 3 days for transverse colectomies. When comparing type of resection before and after ERAS protocol introduction, an increased LOS for left hemicolectomies from 3.09 to 4.03 days (P = .047) was noted, with all other comparisons failing to reach statistical significance. Over time, an initial decrease in LOS for MIS approach after protocol introduction was observed; however, this effect diminished in the ensuing years and had no significant effect overall. Total cost of care was significantly increased post-ERAS for all cohorts except transverse colectomies. No further statistically significant differences were found. CONCLUSION: After an initial improvement in outcomes, continued utilization of ERAS protocols demonstrated no improvement in LOS compared to pre-ERAS data and increased cost overall for patients regardless of site of resection.

RESUMO

OBJECTIVE: This trial aimed to provide randomized controlled data comparing Kono-S anastomosis and stapled ileocolic side-to-side anastomosis. BACKGROUND: Recently, a new antimesenteric, functional, end-to-end, hand-sewn ileocolic anastomosis (Kono-S) has shown a significant reduction in endoscopic recurrence score and surgical recurrence rate in Crohn disease (CD). METHODS: Randomized controlled trial (RCT) at a tertiary referral institution. Primary endpoint: endoscopic recurrence (ER) (Rutgeerts score ≥i2) after 6 months. Secondary endpoints: clinical recurrence (CR) after 12 and 24 months, ER after 18 months, and surgical recurrence (SR) after 24 months. RESULTS: In all, 79 ileocolic CD patients were randomized in Kono group (36) and Conventional group (43). After 6 months, 22.2% in the Kono group and 62.8% in the Conventional group presented an ER [P < 0.001, odds ratio (OR) 5.91]. A severe postoperative ER (Rutgeerts score ≥i3) was found in 13.8% of Kono versus 34.8% of Conventional group patients (P = 0.03, OR 3.32). CR rate was 8% in the Kono group versus 18% in the Conventional group after 12 months (P = 0.2), and 18% versus 30.2% after 24 months (P = 0.04, OR 3.47). SR rate after 24 months was 0% in the Kono group versus 4.6% in the Conventional group (P = 0.3). Patients with Kono-S anastomosis presented a longer time until CR than patients with side-to-side anastomosis (hazard ratio 0.36, P = 0.037). On binary logistic regression analysis, the Kono-S anastomosis was the only variable significantly associated with a reduced risk of ER (OR 0.19, P < 0.001). There were no differences in postoperative outcomes. CONCLUSIONS: This is the first RCT comparing Kono-S anastomosis and standard anastomosis in CD. The results demonstrate a significant reduction in postoperative endoscopic and clinical recurrence rate for patients who underwent Kono-S anastomosis, and no safety issues.ClinicalTrials.gov ID NCT02631967.

RESUMO

QUESTION: Does surgery or conservative management of recurring diverticulitis/ongoing symptoms results in a higher quality of life (QoL) at 5-year follow-up. DESIGN: Randomized controlled trial. SETTING: Multicenter trial in the Netherlands. PATIENTS: Patients aged 18 to 75 years, who presented with either ongoing abdominal complaints (for >3 months) and/or frequently recurring left-sided diverticulitis (>2 episodes in 2 years) after an objectified (via Computed Tomography, Ultrasound or Endoscopy) episode of diverticulitis were included in this study. INTERVENTION: Elective Sigmoid Resection within 6 weeks vs. Conservative Management MAIN OUTCOME:: QoL at 5-year follow-up, as measured by the Gastrointestinal Quality of Life Index (GIQLI). Secondary outcomes included additional QoL assessments (including the EuroQoL-5D-3L, Visual Analogue Score for pain, and the short form 36 health survey) RESULTS:: The intention to treat analysis showed the surgical group had a higher quality of life (GIQLI) score than the conservative group (mean difference 9.7, 95% confidence interval 1.7-17.7, P = 0.018), which approached but did not meet the minimum important difference of 10. This difference was achieved in 67% of those in the operative group versus 57% in the conservative group (many of who eventually underwent surgery). CONCLUSIONS: The study results demonstrate that HRQOL at 5-year follow-up may be improved in patients undergoing surgical resection, although this difference did not meet the MID for the GIQLI.

RESUMO

OBJECTIVE: Evaluate the cost-effectiveness of open, laparoscopic, and robotic colectomy. BACKGROUND: The use of robotic-assisted colon surgery is increasing. Robotic technology is more expensive and whether a robotically assisted approach is cost-effective remains to be determined. METHODS: A decision-analytic model was constructed to evaluate the 1-year costs and quality-adjusted time between robotic, laparoscopic, and open colectomy. Model inputs were derived from available literature for costs, quality of life (QOL), and outcomes. Results are presented as incremental cost-effectiveness ratios (ICERs), defined as incremental costs per quality-adjusted life year (QALY) gained. One-way and probabilistic sensitivity analyses were performed to test the effect of clinically reasonable variations in the inputs on our results. RESULTS: Open colectomy cost more and achieved lower QOL than robotic and laparoscopic approaches. From the societal perspective, robotic colectomy costs $745 more per case than laparoscopy, resulting in an ICER of $2,322,715/QALY because of minimal differences in QOL. From the healthcare sector perspective, robotics cost $1339 more per case with an ICER of $4,174,849/QALY. In both models, laparoscopic colectomy was more frequently cost-effective across a wide range of willingness-to-pay thresholds. Sensitivity analyses suggest robotic colectomy becomes cost-effective at $100,000/QALY if robotic disposable instrument costs decrease below $1341 per case, robotic operating room time falls below 172 minutes, or robotic hernia rate is less than 5%. CONCLUSIONS: Laparoscopic and robotic colectomy are more cost-effective than open resection. Robotics can surpass laparoscopy in cost-effectiveness by achieving certain thresholds in QOL, instrument costs, and postoperative outcomes. With increased use of robotic technology in colorectal surgery, there is a burden to demonstrate these benefits.

RESUMO

The introduction of total mesorectal excision and wider use of laparoscopic surgery pushed the field of colorectal surgery into an era of interfasical dissection. The Japanese suggestion of fascial arrangement of the trunk in a multilaminar, symmetrical and parallel way helps in better understanding of fascial relationship and interfascial planes surrounding the colon and the rectum. However, different interpretations of the multilayer retroperitoneal fascial relationship, complexity of fascial structures within the pelvis and dense adhesion between two apposed fasciae at special points make it still challenging for the surgeon to decide on the precise interfascial plane for colorectal mobilization. Small vessels on fasica propria of the rectum and various retroperitoneal fascia, especially ureterohypogastric fascia show distinctive features. The root of small vessels on fascia propria of the rectum helps to identify the anterolateral and posterolateral interfascial plane in the middle and low rectum. The longitudinal trajectory of small vessel on ureterohypogastric fascia and scarcity interfascial vascular communication between mesocolic and retroperitoneal fascia help the surgeon to find and stay in the interfacial plane during colorectal mobilization. More knowledge of fascial and interfascial plane will certainly help achieve better mesocolic mesorectal integrity and reduce the risk of injuries to autonomic nerves. More anatomical, histological and embryological studies are warranted with respect to relationship between small vessels and fasciae.

RESUMO

Resumen Introducción: Si bien la anastomosis intracorpórea (AI) ha demostrado beneficios clínicos sobre la anastomosis extracorpórea (AE) en la hemicolectomía derecha laparoscópica (HDL), su aplicación ha sido limitada por su dificultad técnica y curva de aprendizaje más larga. El presente estudio busca desarrollar y evaluar un modelo simulado para entrenar este procedimiento. Materiales y Método: Se desarrolló un modelo en base a tejido ex vivo, con colon porcino e intestino bovino, montados en un simulador de laparoscopía. Este se modificó sucesivamente en base a entrevistas semiestructuradas a cirujanos hasta lograr el modelo final. Para evaluar apariencia y reacción al modelo, coloproctólogos, cirujanos y residentes previamente expuestos a entrenamiento simulado, realizaron una ileotransverso anastomosis mecánica en el modelo y luego contestaron una encuesta. Resultados: Doce sujetos participaron. Cuatro coloproctólogos, 4 residentes de coloproctología, 2 residentes de cirugía general, 1 cirujano general y 1 cirujano digestivo. El 91,6% valoró positivamente la ergonomía lograda, mientras que el 83,3% y 75% valoraron positivamente el uso del instrumental y la relación anatómica entre estructuras, respectivamente. Todos los participantes consideraron el modelo útil para entrenar sutura manual laparoscópica, el 91,6% para entrenar enterotomías y 83,3% para entrenar el uso de endograpadora. Todos declararon que el módulo permite entender y reflexionar sobre la técnica propuesta. Conclusión: Este modelo desarrollado sería útil para entrenar habilidades críticas para realizar una AI en HDL. Su incorporación a un programa de entrenamiento en laparoscopía avanzada podría contribuir a acortar la curva de aprendizaje de este procedimiento.


Introduction: Although intracorporeal anastomosis has demonstrated clinical benefits over extracorporeal anastomosis in laparoscopic right hemicolectomy, its application has been limited due to its technical difficulty and longer learning curve. The present study aims to develop and evaluate a simulated model to train this procedure. Materials and Method: An ex vivo tissue model was developed with porcine colon and bovine small bowel mounted in a laparoscopic simulator. This was subsequently modified based on semi-structured interviews to experts until the final model was achieved. To evaluate appearance and reaction to the model, the participants performed an ileocolic mechanical anastomosis in the model and answered a survey. Results: Twelve subjects participated. Four colorectal surgeons, 4 colorectal surgery fellows, 2 residents of general surgery, 1 general surgeon and 1 upper digestive surgeon. Of all subjects, 91.6%, 83.3% and 75% deemed ergonomics achieved, the use of instruments, and the anatomical relationship between structures as similar to reality, respectively. All participants deemed the model useful to train laparoscopic manual suturing, while 91.6% and 83.3% of them considered it useful to train enterotomies and the use of an endostapler, respectively. All declared that the model allows to understand the proposed technique. Conclusion: This model would be useful to train critical skills to perform an intracorporeal anastomosis in laparoscopic right hemicolectomy. Its incorporation into an advanced simulated laparoscopy training program could help shorten the learning curve of this procedure.

RESUMO

BACKGROUND/AIM: Inflammation is known to promote the progression of cancer, and there is increasing evidence that inflammation caused by the antitumor response of the host and post-operative infectious complications worsens the prognosis for colorectal cancer. However, the impact of post-operative inflammation caused by surgical stress on long-term survival is unclear. PATIENTS AND METHODS: A total of 274 patients who underwent curative operation for stage II/III colorectal cancer were enrolled and assessed for the serum C-reactive protein (CRP) levels on postoperative day (POD) 1 and 7 and postoperative infectious complications. RESULTS: The high POD-1 CRP group had a significantly lower relapse-free and overall survival rate than the low POD-1 CRP group. Similarly, the high POD-7 CRP group had a significantly lower relapse-free and overall survival rate than the low POD-7 CRP group. Sub-group analysis limited to patients without postoperative infectious complications indicated that the high POD-7 CRP group tended to have a lower relapse-free survival rate and a significantly lower overall survival rate than the low POD-7 CRP group. CONCLUSION: Inflammation caused by postoperative infectious complications and by surgical stress worsens long-term survival outcomes after a curative operation for colorectal cancer.

RESUMO

Objective: To evaluate the safety, feasibility and short-term efficacy of totally laparoscopic left colectomy for left colon cancer by using overlapped delta-shaped anastomosis technique for digestive tract reconstruction. Methods: A retrospective cohort study was conducted to collect the clinical data of 86 patients with left colon cancer who underwent laparoscopic surgery in Cancer Hospital of Chinese Academy of Medical Sciences from October, 2017 to February, 2019. The patients were divided into totally laparoscopic left-sided colectomy (TLLC) (treatment group, n=25 cases) and laparoscopic-assisted left-sided colectomy (LALC) (control group, n=61 cases). The intraoperative and postoperative data were compared between the two groups. Results: There were no surgical-related deaths in both groups. All the patients in the TLLC group underwent laparoscopic resection, while one patient in the LALC group transfer to open surgery. The operation time in TLLC group and LALC group were (164.5±42.3) min and (171.0±43.1) min, respectively, without statistically significant difference (P=0.516). However, the intraoperative blood loss of patients in the TLLC group was (36.4±22.7) ml, which was significantly less than (52.9±32.2) ml in the LALC group (P=0.026). The anastomosis time in the TLLC group was (39.1±6.5) min, which was significantly longer than (24.9±5.4) min in the LALC group (P<0.001). Postoperative exhaust time in the TLLC group was (2.6±0.5) days, which was significantly shorter than (3.3±0.8) days in the LALC group (P<0.001). The incision length in the TLLC group was (4.2±2.2) cm, significantly shorter than (7.0±2.5) cm in the LALC group (P<0.001). The length of the resected bowel was (21.0±7.3) cm in the TLLC group, which was significantly longer than (17.5±5.4) cm in the LALC group (P=0.037). The length of hospital stay in the TLLC group was (6.2±1.9) days, which was significantly shorter than (7.9±1.5) days in the LALC group (P<0.001). The incidences of postoperative complications in the TLLC group and LALC group were 0 and 4.9% (3/61), respectively, without statistically significant (P=0.553). No anastomotic complications occurred in both groups. During the follow-up period, neither group of patients was hospitalized again, and no tumor metastasis or recurrence occurred. Conclusions: It is safe and feasible to apply the TLLC with overlapped delta-shaped anastomosis in patients with left colon cancer. It has better short-term effects such as shorter incisions, faster recovery, and shorter postoperative hospital stays, and is worthy of further promotion.

RESUMO

RATIONALE: Immunoglobulin G4 (IgG4)-related disease is an increasingly recognized immune-mediated entity that can affect virtually every organ system. Depending on the location of the disease, it can present a wide range of clinical manifestations and even mimic malignancies. Appendiceal involvement in patients with IgG4-related disease is particularly rare and very few cases are reported in the literature. PATIENT CONCERNS: We report a case of IgG4-related appendiceal disease in a 42-year-old woman who presents with a subacute onset of right lower quadrant abdominal pain. DIAGNOSIS: Abdominal computed tomography showed a markedly enlarged appendix, raising the concern of malignancy. The diagnosis of IgG4 appendiceal disease was confirmed by postoperative histopathologic and immunohistochemical examination. INTERVENTIONS: The patient underwent right hemicolectomy. OUTCOMES: After the surgery, the patient had an uneventful recovery and reported a resolution of her symptoms. The serum IgG4 was revaluated 5 days after surgery and returned to its normal values. At the 3-year follow up, the patient had no recurrence of symptoms and her imaging exams remain unremarkable. LESSONS: This study reports the fifth case of IgG4-related appendiceal disease. Increasing awareness of this condition may influence the management of these patients, once patients with IgG4-related disease should be monitored after treatment, due to the risk of recurrence or involvement of other organs.

RESUMO

Objective: To understand the current practice of preoperative bowel preparation in elective colorectal surgery in China. Methods: A cross-sectional questionnaire survey was conducted through wechat. The content of the questionnaire survey included professional title of the participants, the hospital class, dietary preparation and protocol, oral laxatives and specific types, oral antibiotics, gastric intubation, and mechanical enema before elective colorectal surgery. A stratified analysis based on hospital class was conducted to understand their current practice of preoperative bowel preparation in elective colorectal surgery. Result: A total of 600 questionnaires were issued, and 516 (86.00%) questionnaires of participants from different hospitals, engaged in colorectal surgery or general surgeons were recovered, of which 366 were from tertiary hospitals (70.93%) and 150 from secondary hospitals (29.07%). For diet preparation, the proportions of right hemicolic, left hemicolic and rectal surgery were 81.59% (421/516), 84.88% (438/516) and 84.88% (438/516) respectively. The average time of preoperative dietary preparation was 2.03 days. The study showed that 85.85% (443/516) of surgeons chose oral laxatives for bowel preparation in all colorectal surgery, while only 4.26% (22/516) of surgeons did not choose oral laxatives. For mechanical enema, the proportions of right hemicolic, left hemicolic and rectal surgery were 19.19% (99/516), 30.04% (155/516) and 32.75% (169/516) respectively. Preoperative oral antibiotics was used by 34.69% (179/516) of the respondents. 94.38% (487/516) of participants were satisfied with bowel preparation, and 55.43% (286/516) of participants believed that preoperative bowel preparation was well tolerated. In terms of preoperative oral laxatives, there was no statistically significant difference between different levels of hospitals [secondary hospitals vs. tertiary hospitals: 90.00% (135/150) vs. 84.15% (308/366), χ(2)=2.995, P=0.084]. Compared with the tertiary hospitals, the surgeons in the secondary hospitals accounted for higher proportions in diet preparation [87.33% (131/150) vs. 76.78% (281/366), χ(2)=7.369, P=0.007], gastric intubation [54.00% (81/150) vs. 36.33% (133/366), χ(2)=13.672, P<0.001], preoperative oral antibiotics [58.67% (88/150) vs. 24.86% (91/366), χ(2)=12.259, P<0.001] and enema [28.67% (43/150) vs. 15.30% (56/366), χ(2)=53.661, P<0.001]. Conclusion: Although the preoperative bowel preparation practice in elective colorectal surgery for most of surgeons in China is basically the same as the current international protocol, the proportions of mechanical enema and gastric intubation before surgery are still relatively high.

RESUMO

Objective: To systematically evaluate the safety and efficacy of laparoscopic versus open surgery for palliative resection of the primary tumor in stage IV colorectal cancer. Methods: The databases of CNKI, Wanfang, VIP, PubMed, EMBASE and Cochrane Library were searched to retrieve randomized controlled trials (RCT) or clinical controlled trials (CCT) comparing laparoscopic surgery with open surgery for palliative resection of the primary tumor in stage IV colorectal cancer published from January 1991 to May 2019. Chinese search terms included "colorectum/colon/rectum" , "cancer/malignant tumor" , "laparoscopy" , "metastasis" , " IV" ; English search terms included "laparoscop*" , "colo*" , "rect*" , "cancer/tumor/carcinoma/neoplasm" , " IV" , "metasta*" . Inclusion criteria: (1) RCT or CCT, with or without allocation concealment or blinding; (2) patients with stage IV colorectal cancer that was diagnosed preoperatively and would receive resection of the primary tumor; (3) the primary tumor that was palliatively resected by laparoscopic or open procedure. Exclusion criteria: (1) no valid data available in the literature; (2) single study sample size ≤20; (3) subjects with colorectal benign disease; (4) metastatic resection or lymph node dissection was performed intraoperatively in an attempt to perform radical surgery; (5) duplicate publication of the literature. Two researchers independently evaluated the quality of the included studies. In case of disagreement, the evaluation was performed by discussion or a third researcher was invited to participate. The data were extracted from the included studies, and the Cochrane Collaboration RevMan 5.1.0 version software was used for this meta-analysis. Results: Four CCTs with a total of 864 patients were included in this study, including 216 patients in the laparoscopic group and 648 patients in the open group. Compared with the open group, except for longer operation time (WMD=37.60, 95% CI: 26.11 to 49.08, P<0.05), laparoscopic group had less intraoperative blood loss (WMD=-74.89, 95% CI: -144.78 to -5.00, P<0.05), earlier first flatus and food intake after surgery (WMD=-1.00, 95% CI: -1.12 to -0.87, P<0.05; WMD=-1.61, 95%CI: -2.16 to -1.06, P<0.05), shorter hospital stay (WMD=-2.01, 95% CI: -2.21 to -1.80, P<0.05) and lower morbidity of postoperative complication (OR=0.52, 95% CI: 0.35 to 0.77, P<0.05). However, no significant differences were found in time to start postoperative chemotherapy, postoperative chemotherapy rate, and mortality (P > all 0.05). Conclusion: Laparoscopic surgery for palliative resection of the primary tumor is safe and feasible to enhance recovery after surgery by promoting postoperative bowel function recovery, shortening hospital stay and reducing postoperative complication in stage IV colorectal cancer.
