Asano H, Fukano H, Takagi M, Takayama T. Risk factors for the recurrence of stage II perforated colorectal cancer: A retrospective observational study. Asian J Surg 2023; 46:201-206. [PMID: 35331590 DOI: 10.1016/j.asjsur.2022.03.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 03/02/2022] [Accepted: 03/10/2022] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND Patients with perforated colorectal cancer (PCRC) experience higher recurrence rates than those with non-perforated tissue. We identified the promoting factors of stage II PCRC recurrence after R0 surgery. METHOD This retrospective observational study included patients treated for colorectal cancer at a single facility between 2007 and 2016, and compared the clinicopathological features of patients with perforating versus non-perforating stage II tumors who underwent R0 resection, while focusing on recurrences. RESULTS Thirty-two and 112 patients (predominantly men) with perforating and non-perforating tumors, respectively, were included. The perforated group had significantly higher proportions of T4 tumors than the non-perforated group (44% vs. 15%). The perforated group had significantly lower numbers of resected lymph nodes than the non-perforated group (6 vs. 17). Seven of 17 patients with follow-up data in the perforated group experienced recurrence (41%), versus 19 of 104 in the non-perforated group (18%). In the non-perforated group, male sex (89% vs. 60%, p = 0.030), T4 stage (32% vs. 9%, p = 0.029), and fewer resected lymph nodes (12.5 vs. 18.6, p = 0.003) were significantly associated with recurrence; however, no such influences on recurrence were observed in the perforated group. The recurrence sites in the perforated group were mostly local (6 patients, 86%). Conversely, recurrences in the non-perforated group were mostly distant; 8 of 19 patients (42%) had liver metastasis and 1 (5%) had lung metastasis. CONCLUSION Patients with stage II PCRC experienced higher recurrence rates regardless of clinicopathological features and had high local recurrence rates indicating possible local tumor cell dispersal owing to perforation.

Abstract
Development of an anastomotic leak (AL) following intestinal surgery for the treatment of colorectal cancers is a life-threatening complication. Failure of the anastomosis to heal correctly can lead to contamination of the abdomen with intestinal contents and the development of peritonitis. The additional care that these patients require is associated with longer hospitalisation stays and increased economic costs. Patients also have higher morbidity and mortality rates and poorer oncological prognosis. Unfortunately, current practices for AL diagnosis are non-specific, which may delay diagnosis and have a negative impact on patient outcome. To overcome these issues, research is continuing to identify AL diagnostic or predictive biomarkers. In this review, we highlight promising candidate biomarkers including ischaemic metabolites, inflammatory markers and bacteria. Although research has focused on the use of blood or peritoneal fluid samples, we describe the use of implantable medical devices that have been designed to measure biomarkers in peri-anastomotic tissue. Biomarkers that can be used in conjunction with clinical status, routine haematological and biochemical analysis and imaging have the potential to help to deliver a precision medicine package that could significantly enhance a patient's post-operative care and improve outcomes. Although no AL biomarker has yet been validated in large-scale clinical trials, there is confidence that personalised medicine, through biomarker analysis, could be realised for colorectal cancer intestinal resection and anastomosis patients in the years to come.

Abstract
PURPOSE To investigate the frequency of exfoliated cancer cells and the efficacy of rectal washout during intersphincteric resection (ISR) in patients not receiving chemoradiotherapy (CRT) for very low rectal cancer. METHOD The subjects of this prospective study were 16 consecutive patients who underwent ISR without CRT for very low rectal cancer. Brushing cytology of the posterior anorectal wall was performed twice in each step of the ISR procedure and the samples were sent for blind cytological examination to identify exfoliated cancer cells. RESULTS Exfoliated cancer cells were identified in 9 of 13 patients (69%) preoperatively. The number of cancer cells identified after abdominal total mesorectal dissection decreased significantly from 94% (15/16) to 25% (4/16) after transanal irrigation with 2000 mL saline (p < 0.001). No cancer cells were identified after swabbing the anal wall following transanal dissection with purse-string closure of the distal stump. No suture-line recurrence was found during a median follow-up duration of 6 years. CONCLUSION Exfoliated cancer cells, confirmed in 94% of patients after total mesorectal excision, could be eliminated by performing rectal irrigation after clamping the rectum proximal to the tumor and swabbing the anorectal wall during ISR.

Abstract
INTRODUCTION Anastomotic leakage is one of the most severe early complications after colorectal surgery, and it is associated with a high reoperation rate-, and increased in short-term morbidity and mortality rates. It remains unclear whether anastomotic leakage is associated with poor oncologic outcomes. The aim of this study was to determine the impacts of anastomotic leakage on long-term oncologic outcomes, disease-free survival and overall mortality in patients who underwent curative surgery for colorectal cancer. METHODS This single-centre, retrospective, observational cohort study included patients who underwent curative surgery for colorectal cancer between 2005 and 2015 and who had a primary anastomosis. Survival- and multivariate cox regression analyses were performed to adjust for confounding. RESULTS A total of 1984 patients had a primary anastomosis after surgery. The overall incidence of anastomotic leakage was 7.5%; 19 patients were excluded because they were lost to follow-up. Of the remaining 1965 patients, 41 (2.1%) developed local recurrence associated with anastomotic leakage [adjusted hazard ratio (HR) = 2.25; 95% confidence interval (CI) 1.14-5.29; P = 0.03]. Distant recurrence developed in 291(14.8%) patients with no association with anastomotic leakage [adjusted HR = 1.30 (95% CI: 0.85-1.97) P = 0.23]. Anastomotic leakage was associated with increased long-term mortality [adjusted HR = 1.69 (95% CI 1.32-2.18) P < 0.01]. Five year disease-free survival was significantly decreased in patients with anastomotic leakage, (log rank test P < 0.01). CONCLUSION Anastomotic leakage was significantly associated with increased rates of local recurrence, disease free-survival and overall mortality. Associations of anastomotic leakage with distant recurrence was not found.

Abstract
PURPOSE We estimated the incidence of anastomosis leakage and explore possible risk factors and oncologic outcomes following laparoscopic right-side colon resection among colon cancer patients. MATERIALS AND METHODS We retrospectively analyzed 423 patients who were diagnosed with appendiceal, cecal, ascending, or hepatic flexure colon cancer who underwent laparoscopic colonic resection and anastomosis between September 2006 and July 2014. We compared short-term and long-term outcomes between no-leakage and leakage groups. RESULTS There were 16 cases of right-side anastomosis leakage in a total 423 colon cancer cases (3.78%). The risk of leakage was increased in smokers (odds ratio=6.592, P=0.007) and with a longer operating time (odds ratio=1.024, P<0.001). There were no significant differences between the groups in local recurrence (P=0.106), overall survival (P=0.055), or cancer-specific survival (P=0.235). CONCLUSIONS Smoking and long operating time are risk factors for right-side colon anastomosis. There were no significant differences in oncologic outcomes.

Abstract
Background Local recurrence of colorectal cancer is a major cause of morbidity and mortality that usually implies a worse prognosis. Its etiopathogenesis is still a subject of debate. Recurrence on the perineal wound caused by anal retractor device is rarely reported. Case presentation We present the case of a 75-year-old woman with perineal skin recurrence on the site of Lone Star Retractor™ from rectal adenocarcinoma. The patient underwent a curative proctectomy followed by a hand-sewn coloanal anastomosis using Lone Star Retractor™ 2 years ago for a tumor of the lower rectum. The recurrence was most likely caused by the seeding of exfoliated tumor cells into the perianal skin which was abraded by the retractor. Conclusion This case is the fourth case reported in the literature and highlights the importance of the use of less traumatic endoanal retractors to prevent such perianal recurrence. Recurrence on the perineal wound caused by anal retractor device is rare but possible. Further studies are needed to define preventive measures able to reduce cutaneous implants.

Abstract
BACKGROUND Transanal total mesorectal excision (taTME) is an altogether different approach to rectal cancer surgery, and the effects of carbon dioxide (CO2) on this dissection remain poorly described. METHODS This article critically examines the effect of carbon dioxide insufflation and the workspace it creates during the process of taTME. The unique aspects of insulation with this approach are governed by the laws of physics, especially the principles of fluid dynamics, an area that remains poorly described for laparoscopy and not at all described for taTME. RESULTS A summary of established factors which affect the operative field of the taTME surgeon is delineated and further explored. In addition, new concepts regarding gas delivery, such as insufflation vectors, anatomic distortion, hyper-dissection, and workspace volume rate of change as a function of taTME dissection time, are addressed. Collectively, these factors pose important challenges which increase case complexity and are thus essential for taTME trainers and trainees alike to understand. CONCLUSIONS Although an invisible gas, CO2 insufflation with taTME produces markedly visible effects which are imposed upon the operative field. This can result in anatomic distortion and misperception of operative planes. Thus, practicing taTME surgeons should be cognizant of these effects.

Abstract
Background The prognostic significance of free cancer cells detected in peritoneal fluid at the time of rectal surgery remains unclear. A substantial number of patients will develop metastatic disease even with successful local treatment. This prospective non-randomized study investigated the prognostic value of intraperitoneal free cancer cells harvested in peritoneal lavage after surgery for rectal cancer. Mutational hotspots in mitochondrial DNA were examined as potential molecular signatures to detect circulating intraperitoneal free cancer cells when present in primary tumor and in lavage. Methods Point mutations in mitochondrial DNA amplifications were determined in primary tumors and corresponding exfoliated intraperitoneal free cancer cells in lavage from 191 patients with locally advanced rectal cancer scheduled for radical treatment. Mitochondrial DNA target sequences were amplified by polymerase chain reaction and base substitutions were detected by denaturant, cycling temperature capillary electrophoresis. Detection of intraperitoneal free cancer cells was correlated to survival. Results Of 191patients analyzed, 138 (72%) were identified with somatic mitochondrial point mutations in rectal cancer tumors. From this fraction, 45 patients (33%) had positive lavage fluid with corresponding somatic mtDNA point mutations in lavage representing circulating intraperitoneal free cancer cells. There was no significant survival difference between patients identified with or without somatic mitochondrial DNA point mutations in the corresponding lavage. Conclusion Somatic mitochondrial DNA point mutations identified in primary rectal tumors enable detection of circulating intraperitoneal free cancer cells in lavage fluid. Intraperitoneal free cancer cells harvested from lavage immediately after surgery for rectal cancer does not represent an independent prognostic factor on survival.

Abstract
BACKGROUND In rectal cancer, anastomotic leakage was reported to have a negative impact on both short- and long-term outcomes. However, there is limited data on the impact of anastomotic leakage on oncologic outcomes in patients with colon cancer. We aimed to evaluate the impact of anastomotic leakage on disease recurrence and long-term survival after curative resection of colon cancer. METHODS This multicenter, retrospective cohort study of 4,919 consecutive patients utilized data from the Japanese Society for Cancer of the Colon and Rectum. Multivariable Cox regression analysis was used to adjust for confounding. RESULTS The incidence of anastomotic leakage was 2.5% and 30-day mortality was 0.21%. The 5-year overall survival rate was 80.8% in the anastomotic leakage group, compared with 90.3% in the no leak group (P = .001). In the multivariable analysis, anastomotic leakage was significantly associated with reduced overall survival rate (hazard ratio = 1.84; 95% confidence interval, 1.06-2.96). Overall disease recurrence rate was 14.1%: 21.2% in the anastomotic leakage group and 13.9% in the no leak group. There was a significant association between anastomotic leakage and local recurrence (hazard ratio = 4.63; 95% confidence interval, 1.60-10.6). In contrast, anastomotic leakage was not significantly associated with total distant recurrence. However, anastomotic leakage did show a tendency toward increasing peritoneal recurrence, although it did not reach statistical significance (hazard ratio = 2.59; 95% confidence interval, 0.79-6.29). CONCLUSION In our study population, anastomotic leakage was associated with reduced overall survival and with increased rate of local recurrence after curative resection for colon cancer.

Abstract
Anastomotic leakage (AL) is a well-known cause of morbidity after low anterior resection (LAR) for rectal cancer, but its impact on oncologic outcome is not well understood. The aim of this study is to investigate the impact of AL on long-term oncologic outcome and to identify factors associated with AL that may affect prognosis after LAR for rectal cancer.A retrospective analysis of patients who underwent curative resection for rectal cancer without diverting stoma was performed. To investigate AL related factors that may be associated with oncologic outcome, Clavien-Dindo grades, prognostic nutritional indices (PNI) and inflammatory indices were included.One hundred and one patients out of a total of 1258 patients developed postoperative AL, giving an AL rate of 8.0%. Patients with AL showed poorer disease-free survival (DFS), than patients without AL (hazard ratio [HR] = 1.6; 95% confidence intervals [CI]: 1.1-2.5; P = 0.01). In patients who developed AL, age over 60 (HR = 2.2; 95% CI: 1.1-4.7; P = 0.033), advanced pathologic stage (HR = 2.4; 95% CI: 1.4-4.0; P = 0.001), suppressed neutrophil-proportion (≤80%) (HR = 2.6; 95% CI: 1.2-5.8; P = 0.019) and PNI <36 (HR = 3.5; 95% CI: 1.2-9.6; P = 0.018) were associated with poorer DFS.AL was associated with poorer DFS. In patients with AL, a suppressed neutrophil-proportion and decreased PNI below 36 were associated with tumor recurrence.

Abstract
Over the past 3 years, colorectal surgeons have begun to adapt the technique of transanal total mesorectal excision. As international experience has been quickly forged, an improved recognition of the pitfalls and the practical details of this disruptive technique have been realized. The purpose of this technical note was to express the various nuances of transanal total mesorectal excision as learned during the course of its clinical application and international teaching, so as to rapidly communicate and share important insights with other surgeons who are in the early adoption phase of this approach. The technical points specific to transanal total mesorectal excision are addressed herein. When correctly applied, these will likely improve the quality of surgery and decrease morbidity attributable to inexperience with the transanal approach to total mesorectal excision.

Abstract
BACKGROUND Anastomotic leaks after restorative resections for rectal cancer may lead to worse long-term outcomes. OBJECTIVE The purpose of this study was to evaluate the best current evidence assessing anastomotic leaks in rectal cancer resections with curative intent and their impact on survival and cancer recurrence. DATA SOURCES A meta-analysis was performed using MEDLINE, EMBASE, and Cochrane search engines for relevant studies published between January 1982 and January 2015. STUDY SELECTION Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology was used to screen and select relevant studies for the review using key words "colorectal surgery; colorectal neoplasm; rectal neoplasm" and "anastomotic leak." INTERVENTION Anastomotic leak groups were compared with nonanastomotic leak groups. MAIN OUTCOME MEASURES ORs were calculated from binary data for local recurrence, distant recurrence, and cancer-specific mortality. A random-effects model was then used to calculate pooled ORs with 95% CIs. RESULTS Eleven studies with 13,655 patients met the inclusion criteria. This included 5 prospective cohort and 6 retrospective cohort studies. Median follow-up was 60 months. Higher cancer-specific mortality was noted in the leak group with an OR of 1.30 (95% CI, 1.04-1.62; p < 0.05). Local recurrences were more likely in rectal cancer resections complicated by anastomotic leaks (OR = 1.61 (95% CI, 1.25-2.09); p < 0.001). Distant recurrence was not more likely in the anastomotic leak group (OR = 1.07 (95% CI, 0.87-1.33); p = 0.52). LIMITATIONS All 11 studies are level 3 evidence cohort studies. Additional sensitivity analyses were performed to minimize cross-study heterogeneity. CONCLUSIONS Anastomotic leaks after restorative resections for rectal cancer adversely impact cancer-specific mortality and local recurrence.

Abstract
PURPOSE To assess the effectiveness of rectal wash out in preventing local recurrence for patients who undergo anterior resection for recto-sigmoid cancer. MATERIALS AND METHODS A best evidence topic was constructed according to a structured protocol. Medline 1948-2015 and EMBASE 1980 to 2015 using the OVID interface: ( Rectal) AND (Washout) AND (Anterior Resection). In addition, the reference lists of the relevant papers were searched. OUTCOMES Eight papers among the 17 relevant articles were identified as representing the best evidence including 3 prospective non-randomized studies, 1 retrospective non randomized study and 4 meta-analyses. CONCLUSIONS On the basis of current evidence, rectal washout does not stop local recurrence of cancer after anterior resection or left sided colonic resection, but it may reduce the rate of local recurrence. A randomised controlled trial to address this issue would formally answer this question.

Abstract
The growth of residual tumor cells may cause postoperative colorectal anastomotic recurrence, which mainly exists in the intestine; however, rectal washout can significantly reduce the number of free tumor cells in the intestinal cavity and decrease the local recurrence rate. Clinical application of rectal washout has been tried in operation, but the effect remains controversial. This paper mainly introduces the method of rectal washout, washout fluid type, amount of washout fluid, relation of rectal washout with local recurrence, with emphasis on the influence of reasonable application of rectal washout on prognosis and recurrence of rectal cancer after surgery.

Abstract
Anastomotic dehiscence (AD) requiring reoperation is the most severe complication following anterior rectal resection. We performed a systematic review on studies that describe AD requiring reoperation and its subsequent mortality after anterior resection for rectal carcinoma. A systematic search was performed on published literature. Data on the definition and rate of AD, the number of ADs requiring reoperation, the mortality caused by AD, and the overall postoperative mortality were pooled and analyzed. A total of 39 studies with 24,232 patients were analyzed. The studies varied in incidence and definition of AD. Systematic review of the data showed that the overall rate of AD was 8.6%, and the rate of AD requiring reoperation was 5.4%. The postoperative mortality caused by AD was 0.4%, and the overall postoperative mortality was 1.3%. We found considerable risk and mortality for AD requiring reoperation, which largely contributed to the overall postoperative mortality.

Abstract
OBJECTIVE We sought to characterize the effect of postoperative complications on long-term survival after colorectal cancer (CRC) resection. BACKGROUND The impact of early morbidity on long-term survival after curative-intent CRC surgery remains controversial. METHODS The Veterans Affairs Surgical Quality Improvement Program and Central Cancer Registry databases were linked to acquire perioperative and cancer-specific data for 12,075 patients undergoing resection for nonmetastatic CRC (1999-2009). Patients were categorized by presence of any complication within 30 days and by type of complication (noninfectious vs infectious). Univariate and multivariate survival analyses adjusted for patient, disease, and treatment factors were performed, excluding early deaths (<90 days). Subset analysis was performed to determine the specific impact of severe postoperative infections. RESULTS The overall morbidity and infectious complication rates were 27.8% and 22.5%, respectively. Patients with noninfectious postoperative complications were older, had lower preoperative serum albumin, had worse functional status, and had higher American Society of Anesthesiologists scores than patients with infectious complications and without complications (all P < 0.001). The presence of any complication was independently associated with decreased long-term survival [hazard ratio, 1.24; 95% confidence interval (1.15-1.34)]. Multivariate analysis by complication type demonstrated increased risk only with infectious complications [hazard ratio, 1.31; 95% confidence interval (1.21-1.42)]. Subset analysis demonstrated this effect predominantly in patients with severe infections [hazard ratio, 1.41; 95% confidence interval (1.15-1.73)]. CONCLUSIONS The presence of postoperative complications after CRC resection is associated with decreased long-term survival, independent of patient, disease, and treatment factors. The impact on long-term outcome is primarily driven by infectious complications, particularly severe postoperative infections.

Abstract
BACKGROUND AND OBJECTIVE Rectal washout with saline solution may theoretically prevent anastomotic recurrence in patients with resectable rectal cancer, although exact clinical effects have not yet been determined. In order to derive a more precise estimation of the relationship, the present meta-analysis was performed. METHOD Relevant studies were identified by a search of Medline, Embase and Google Website with no restrictions to September 1, 2013, and included in the systematic review and meta-analysis. RESULTS 5 trials (642 participants) were included to assess the association between rectal washout with saline solution and anastomotic recurrence. The rate of anastomotic recurrence (AR) was 6.23% (40/642), with the pooled OR derived from the five studies being 0.32 (95 % CI=0.15-0.70, P=0.004). The pooled OR derived from the TME and radical resection subgroups were 0.72 (95%CI=0.16-3.12, P=0.66) and 0.51 (95%CI=0.13-1.96, P=0.32), respectively. CONCLUSION Results from this analysis show that intra-operative rectal washout with mere saline solution largely reduces the risk of anastomotic recurrences in patients with resectable rectal cancer.

Abstract
OBJECTIVE This study was designed to explore the factors influencing local recurrence and survival for low rectal cancer with pT1-2NxM0 stage after an abdominoperineal resection (APR). METHODS Data of 429 patients confirmed to have pT1-2NxM0 after APR were reviewed. RESULTS The recurrence rate in patients with intraoperative perforation, less than 12 lymph nodes (LNs) harvested, T2 staging, and positive circumferential resection margin (CRM) was 25.1, 19.9, 9.5, and 26.1% compared with 6.9, 7.0, 0, and 5.8% in patients with no perforation, 12 or more LNs harvested, T1, and negative CRM. The 5-year survival rate in patients with age of at least 70, perforation, less than 12 LNs harvested, T2, and positive CRM was 71.1, 60.8, 58.8, 69.9, and 46.0%, but 73.4, 73.5, 73.8, 89.4, and 75.0% in patients with age less than 70, no perforation, 12 or more LNs harvested, T1, and negative CRM. Meanwhile, patients with N0, N1, and N2 had a survival rate of 90.7, 69.9, and 63.9%. Multivariate analysis showed that perforation (P<0.001), number of LNs harvested (P<0.001), T staging (P<0.001), differentiation (P=0.045), and CRM status (P=0.002) were associated with local recurrence, whereas age of the patients (P=0.023), N staging (P<0.001), differentiation (P=0.011), and CRM status (P=0.004) were associated with survival. CONCLUSION APR was affected by patients' age, operation performer, perforation, number of LNs harvested, T staging, N staging, differentiation, and CRM status. Perforation, number of LNs harvested, T staging, differentiation, and CRM status were independent factors for recurrence; meanwhile, age of the patients, N staging, differentiation, and CRM status were independent factors influencing survival.

Abstract
BACKGROUND Rectal washout can prevent local recurrence after anterior resection of rectal cancer. Few studies have focused particularly on the association between irrigation fluids volume or agents and the risk of local recurrence after anterior resection of rectal cancer. OBJECTIVE To estimate the association between irrigation fluids types, volumes of rectal washout and risk of local recurrence after anterior resection for cancer. DATA SOURCES Relevant studies were identified by a search of Medline, Embase, Wiley Online Library, China National Knowledge Infrastructure, Cochrane Oral Health Group Specialized Register, Wanfang databases and Google Website from their inception until October 18,2013. STUDY SELECTION Studies reporting the association between rectal washout types and volumes and risk of local recurrence after anterior resection for cancer were included. INTERVENTIONS Eligible studies used rectal washout. Control groups were defined as no washout. STUDY APPRAISAL AND SYNTHESIS METHODS Random-effects model were used to obtain summary estimates of RR and 95% CI, with Stata version 11 and RevMan 5.2.5 softwares used. The quality of report was appraised in reference to the MINORS item. RESULTS Of the 919 rectal cancer patients in 8 included studies, a total of 61(6.64%) cases of local recurrence were reported, with a pooled RR 0.51 (95%CI = 0.28-0.92, P = 0.03). The RRs 0.37 and 0.39 in normal saline and washout volume (≥ 1500 ml normal saline) subgroup, respectively, indicated that rectal washout with normal saline, or ≥ 1500 ml in volume could significantly reduce local recurrence (LR) rate (95% CI = 0.17-0.79, P = 0.01; 95% CI = 0.18-0.87, P = 0.02) after anterior resection for cancer. LIMITATION The included studies were non-randomized observational studies, with diversity of study designs. CONCLUSION Rectal washout with normal saline alone can reduce the risk of local recurrence in patients with resectable rectal cancer, and 1.5 liters rectal washout in volume is recommended.

Abstract
This study was designed to explore the influence of intra-operative perforation on prognosis of low rectal cancer after APR and to investigate the risk factors of perforation. Perforation is not scarce during the procedure of abdominoperineal resection (APR). There is no consensus on perforation rate and related risk factor for APR. Data of 925 patients who received APR for low rectal cancer between January 2000 and August 2008 were reviewed. The intra-operative perforation rate was 7.4 % (68/925). The recurrence rate was 28.6 % in patients with intra-operative perforation compared with 6.8 % in patients with no perforation (P < 0.001); 5-year survival rate in patients with perforation was 41.4 and 66.3 % in patients with no perforation. Univariate analysis showed that intra-operative perforation affected recurrence rate and survival significantly (P < 0.001, P < 0.001); multivariate analysis revealed that intra-operative perforation was an independent prognostic factors for recurrence (RR: 3.087, P < 0.001), while not for survival (RR: 1.331, P = 0.051). Patients aged more than 70 years, T3 tumor and treated by general surgeon had higher perforation rate (P = 0.001, P = 0.004, P = 0.008). Intra-operative perforation affected the prognosis of low rectal cancer after APR significantly. Elderly patient aged more than 70 years, T3 tumor and general surgeon who performed operation were three risk factors of increased perforation rate.

Abstract
BACKGROUND It has been shown that intraluminal washout (WO) can prevent local recurrence (LR) of rectal cancer. This meta-analysis was to evaluate the association of rectal WO and the risk of LR after anterior resection in patients with rectal cancer. METHODS The relevant studies were identified by a search of the MEDLINE, Embase, Wiley Online Library, and Cochrane Oral Health Group Specialized Register with no restrictions on October 18, 2013, and these studies were included in a systematic review and meta-analysis. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in fixed effects model. RESULTS A total of nine studies were included in our study, yielding a total of 5519 patients, and pooled ORs for overall LR in corresponding subgroups were calculated. Rectal WO was associated with a lower risk for LR (240/4176, 5.75% versus 9.75%, 131/1343, OR = 0.53, 95% CI = 0.42-0.68, and P < 0.00001) in patients with anterior resection, having total mesorectal excisions (234/3942, 5.93% versus 9.34%, 97/1039, OR = 0.59, 95% CI = 0.46-0.75, and P < 0.00001), and after radical resection (RR; 122/2665, 4.99% versus 8.90%, 74/831, OR = 0.56, 95% CI = 0.41-0.78, and P = 0.0005), with an overall LR rate of 6.72% (371/5519). But, the stability of RRs is not high in the total mesorectal excisions or RR subgroup by sensitivity analysis. CONCLUSIONS The use of rectal WO decreases risks of LR in patients after anterior resection of cancer.

Abstract
BACKGROUND The oncologic impact of anastomotic leakage after rectal cancer surgery remains controversial. METHODS Between January 1999 and December 2010, 1,148 patients with rectal cancer who underwent curative surgery with sphincter preservation were retrospectively reviewed. Using the propensity score matching method, 328 patients with fibrin glue were matched to 328 patients without fibrin glue, and oncologic outcomes were compared in the matched groups. RESULTS Anastomotic leakage was diagnosed in 76 patients (6.6%). On multivariate analysis, fibrin glue was the independent predictor of prevention of anastomotic leakage. In the 656 matched groups, patients with anastomotic leakage had significantly worse 5-year local recurrence-free survival and disease-free survival than those without leakage. Multivariate analysis confirmed that anastomotic leakage was an independent prognostic factor of both local recurrence and disease-free survival, but the use of fibrin glue was not associated with the long-term outcomes when controlling for confounders. CONCLUSIONS Anastomotic leakage is a major independent prognostic factor for long-term outcomes. Fibrin glue has a protective effect of anastomosis, without oncologic advantages.

Abstract
OBJECTIVES Due to concerns about implantation of malignant cells during surgery for rectal cancer, traditionally, intraoperative rectal washout (IORW) has been performed to prevent local recurrence. But with the advent of laparoscopic surgery, many surgeons have abandoned this practice. The aim of this study was to assess current practice among colorectal surgeons in the UK. METHODS A 10-item questionnaire was sent by email to 452 consultant surgeons, who were members of the Association of Coloproctology of Great Britain & Ireland, and had previously agreed to participate in research projects. RESULTS The mean age of the 149 responders (n = 149, 33.0%) was 49.2 years. The mean number of years in independent practice was 12.1, and the mean number of rectal cancer cases performed per year was 20.3 and 20.6, in the years 2010 and 2011 respectively. 74.3% of the responders believed that there is an advantage in performing IORWs in rectal cancer resections. Of the 71.8% of all responders who performed laparoscopic rectal cancer resections, 54.8% routinely performed IORWs during laparoscopic resections. However, 87.2% of all responders performed IORWs in open resections for rectal cancer, and 79.2% had routinely performed IORWs before the advent of laparoscopic rectal cancer surgery. CONCLUSIONS Most colorectal surgeons believe that there is an advantage in performing IORWs. Although, most surgeons would routinely perform IORWs in open resections, they do not routinely perform these in laparoscopic resections.

Impact of positive intraabdominal lavage cytology on the long-term prognosis of colorectal cancer patients. World J Surg 2013; 36:2714-21.

Abstract
BACKGROUND Our aim was to investigate the presence of free cancer cells found in lavage cytology specimens taken from the proximity of tumors during the course of curative open and laparoscopic colorectal resections and then examine and compare the long-term disease outcomes in cases of negative and positive cytology. Based on the results, we were hoping to identify the place of peritumoral lavage cytology among prognostic factors for disease recurrence. METHODS Between January 1, 2005 and December 31, 2007 intraoperative peritoneal lavage cytology was performed in 145 patients who underwent curative colorectal procedures. In all, 37 of the procedures were laparoscopic resections. RESULTS Malignant cells were detected in the intraoperative peritoneal lavage cytology samples from 25 patients. Median follow-up was 47 months (3-81 months). Among the 25 patients with positive cytology; locoregional recurrence or distant metastasis was found in 14 during this period (56 %), whereas among the 120 patients with negative cytology the incidence was 28 (23 %). CONCLUSIONS The impact of tumor stage, lymph node status, and peritoneal lavage cytology on recurrence rates is significant. Tumor, nodal, and lavage cytology status can be organized hierarchically in relation to time of recurrence. Cytology is most important, with positivity rendering long-term prognosis unfavorable. When comparing surgical techniques (open versus laparoscopic), we found no significant difference in recurrence rates. Our study has shown that conventional peritoneal lavage cytology is a prognostic factor in the case of patients undergoing curative colorectal operations.

Abstract
BACKGROUND Implantation of exfoliated cancer cells has been suggested as a possible mechanism of local recurrence at the site of colorectal anastomosis. Intraoperative rectal washout has been suggested to eliminate free cancer cells; however, there is no conclusive evidence of a beneficial effect of intraoperative rectal washout on local recurrence after anterior resection of rectal cancer. METHODS Studies published through February 2012 evaluating the impact of intraoperative rectal washout for local recurrence or positive cytology from donuts wash were identified by an electronic literature search. A meta-analysis was performed using the DerSimonian-Laird random-effects models to compute risk ratio (RR) along with 95% confidence intervals (CI). RESULTS Nine studies met the inclusion criteria, yielding a total of 5,395 patients. Eight studies evaluated overall local recurrence, including anastomotic recurrence, and five of the eight studies evaluated anastomotic recurrence separately. Two studies evaluated positive cytology from donuts wash. Local recurrence rate was 5.79% in the washout group and 10.05% in the no washout group-a difference that was statistically significant (RR = 0.57; 95% CI = 0.46-0.71; P < 0.00001). Rectal washout significantly reduced the risk of anastomotic recurrence (RR = 0.3; 95% CI = 0.12-0.71; P = 0.007). No influence of rectal washout was observed on positive cytology from donuts wash. CONCLUSIONS From the results of this meta-analysis, it may be justified to recommend intraoperative rectal washout to prevent local recurrence in rectal cancer surgery.

Abstract
Proper anastomotic healing is dependent upon many factors including adequate blood flow to healing tissue. The aim of this study was to investigate the impact of vascular endothelial growth factor (VEGF(165)) transfection on anastomotic healing in an ischemic gastrointestinal anastomosis model. Utilizing an established opossum model of esophagogastrectomy followed by esophageal-gastric anastomosis, the gastric fundus was transfected with recombinant human vascular endothelial growth factor via direct injection of a plasmid-based nonviral delivery system. Twenty-nine animals were divided into three groups: two concentrations of VEGF and a control group. Outcomes included VEGF mRNA transcript levels, neovascularization, tissue blood flow, and anastomotic bursting pressure. To determine whether local injection resulted in a systemic effect, distant tissues were evaluated for VEGF transcript levels. Successful gene transfection was demonstrated by quantitative polymerase chain reaction analysis of anastomotic tissue, with significantly higher VEGF mRNA expression in treated animals compared to controls. At the gastric side of the anastomosis, there was significantly increased neovascularization, blood flow, and bursting pressure in experimental animals compared to controls. There were no differences in outcome measures between low- and high-dose VEGF groups; however, the high-dose group demonstrated increased VEGF mRNA expression across the anastomosis. VEGF production was not increased at distant sites in treated animals. In this animal model, VEGF gene therapy increased VEGF transcription at a healing gastrointestinal anastomosis without systemic VEGF upregulation. This treatment led to improved healing and strength of the acutely ischemic anastomosis. These findings suggest that VEGF gene therapy has the potential to reduce anastomotic morbidity and improve surgical outcomes in a wide array of patients.

Abstract
PURPOSE The purpose of this study was to predict the postoperative organ derangement before surgery and to select the optimal surgical methods for a perforation due to colorectal cancer. METHODS The Mannheim Peritonitis Index (MPI) was used to determine the preoperative status and Sequential Organ Failure Assessment (SOFA) score for postoperative status, retrospectively. RESULTS There were 25 cases of colorectal cancer-related colon perforation. These patients were classified as having a preoperative MPI ≤ 29 or ≥ 30 and the mean postoperative SOFA scores were 2.30 ± 2.45 and 7.93 ± 3.45 (p = 0.0002), respectively. Seven of 20 patients who underwent tumor resection received a bowel anastomosis without a stoma. The MPI of these seven patients was low (23.1 ± 7.47) and there were no severe postoperative organ disorders (SOFA score 1.86 ± 2.26). Eighteen of the 25 patients had no distant metastasis. Eight of these 18 patients underwent lymph node (LN) dissection, including intermediate LNs, while the other 10 cases only had the pericolic/perirectal LNs dissected. The average preoperative MPI was 23.9 ± 7.68 and 32.8 ± 5.77, and the postoperative SOFA scores were 3.75 ± 3.01 and 7.10 ± 5.34, respectively. CONCLUSION The MPI could be used to predict postoperative organ disorders and thus represents a useful index that can be used to determine the optimal surgical methods.

Abstract
BACKGROUND We analyzed factors associated with the occurrence of anastomotic leakage (AL) and its impact on long-term survival in patients who have undergone resection for rectal cancer. We also investigated the effect of fecal diversion on survival. METHOD Clinical data of patients who received surgery for rectal cancer were reviewed. The difference in AL incidence among different groups was compared and survival rates were calculated. Cox's proportional hazards model was used to compare survival in patients who developed AL or received diversion stoma with those who did not. RESULTS Of 999 patients who received resection and anastomosis, 53 patients experienced AL. Multivariate analysis revealed advanced age (P = 0.009) and operative method (P = 0.002) were independent risk factors for AL. Anastomotic leakage was an independent risk factor for overall recurrence (HR 2.30; 95% CI 1.12-4.73). Anastomotic leakage and fecal diversion were independent prognostic factors of overall survival (P = 0.002 and P < 0.001, respectively), cancer-specific survival (P = 0.002 and P < 0.001, respectively), and disease-free survival (P < 0.001, respectively). CONCLUSIONS Patients who are older and have anastomosis at the anorectal junction or dentate line have an increased risk of AL. A diversion stoma does not appear to decrease the incidence of anastomotic leakage, but may decrease the need of reoperation when leakage occurred. Anastomotic leakage and fecal diversion are independent prognostic factors of overall, cancer-specific, and disease-free survival.

Abstract
BACKGROUND Anastomotic leakage is associated with high mortality, high reoperation rate, and increased hospital length of stay. Although many studies have examined the risk factors for anastomotic leak, large prospective series that report on long-term survival rates are lacking. METHODS Data of 1576 patients who underwent primary resection and anastomosis for colorectal adenocarcinoma at a single institution from 1984 to 2004 were prospectively collected. Anastomotic leaks (LEK) were classified as radiological (RAD), local (LOC), or generalised (GEN). Logistic regression analysis of 21 variables was undertaken. Overall survival, cancer-related survival, and disease-free survival were analysed using the Kaplan-Meier method. RESULTS Mean age of the patients was 67 years (SD = 12.5) and 834 (52.9%) were male. An LEK was more likely when relatively major gynaecological (tubo-oophorectomy, P = 0.004; hysterectomy, P = 0.006) or urological (total cystectomy, P = 0.014) procedures were performed during the same operative session. Other significant factors were anterior resection (P < 0.001), anastomosis using an intraluminal stapling device (P = 0.005), abdominal drain via laparoscopic port (P = 0.024), postoperative blood transfusion (P < 0.001), primary cancer site at the rectum (P = 0.016), and TNM stage of T2 or higher (P = 0.026). Having an LEK showed significant impact on overall (P = 0.021), cancer-related (P = 0.006), and disease-free (P = 0.001) survival. CONCLUSION In this prospective study, advanced tumour stage, distal site, and need for postoperative blood transfusion were associated with increased rates of anastomotic leakage. In addition to their high risk of immediate postoperative morbidity and mortality, both localized and generalized leaks had similarly negative impacts on overall, cancer-related, and disease-free survival.

Abstract
AIM The impact of anastomic leakage (AL) on the oncological outcome after anterior resection (AR) for rectal cancer is still controversial. We explored the impact of AL regarding local recurrence (LR), distant metastasis and overall recurrence (OAR). Overall and cancer-specific survival was analysed. METHOD Patients undergoing AR for rectal cancer with a registered AL between 1995 and 1997 and a control group were identified in the Swedish Rectal Cancer Registry. The medical records were retrieved for additional data and validation. Differences in the oncological outcome at 5-year follow-up were analysed with multivariate methods. RESULTS After validation, 114 patients with AL and 136 control patients with locally radical surgery for tumours in tumour-node-metastasis stages I-III were analysed. There was no difference detected between patients with AL and control patients regarding rates of LR [8% (9 of 114) vs 9% (12 of 136); P = 0.97], distant metastasis [18% (20 of 114) vs 23% (31 of 136); P = 0.37] and OAR [19% (22 of 114) vs 28% (38 of 136); P = 0.15]. The 5-year cancer-specific survival was almost 80% in both groups. In multivariate analysis, AL was not a risk factor of LR, distant metastasis or OAR and had no impact on 5-year overall or 5-year cancer-specific survival. Irrespective of the occurrence of AL, preoperative radiotherapy (P = 0.055) and rectal washout (P = 0.046) reduced the LR rate, but did not influence survival. CONCLUSION Anastomotic leakage was not proved to be a risk factor of worse oncological outcome. Hence, additional adjuvant treatment or extended follow-up on the basis of the occurrence of AL after AR might not be justified.

Abstract
BACKGROUND Adenocarcinomas of the rectum shed viable cells, which have the ability to implant. Intraoperative rectal washout decreases the amount and viability of these cells, but there is no conclusive evidence of the effect of rectal washout on local recurrence after rectal cancer surgery. METHODS Data were analysed from a population-based registry of patients who had anterior resection from 1995 to 2002 and were followed for 5 years. Rectal washout was performed at the discretion of the surgeon. National inclusion of patients with rectal cancer and follow-up was near complete (approximately 97 and 98 per cent respectively). RESULTS A total of 4677 patients were analysed (3749 who had washout, 851 no washout and 77 with information missing); 52.0 per cent of patients in the washout group and 41.4 per cent in the no-washout group had preoperative radiotherapy (P < 0.001). Local recurrence rates were 6.0 and 10.2 per cent respectively (P < 0.001). Univariable and multivariable logistic regression analyses produced odds ratios that favoured washout: 0.56 (95 per cent confidence interval (c.i.) 0.43 to 0.72) and 0.61 (0.46 to 0.80) respectively (both P < 0.001). In multivariable analysis restricted to patients who had curative surgery, the odds ratio was 0.59 (95 per cent c.i. 0.44 to 0.78; P < 0.001). CONCLUSION There was a more favourable outcome in patients after rectal washout than without.

Abstract
PURPOSE Identification of risk factors of poor oncological outcome in rectal cancer surgery is of utmost importance. This study examines the impact of incidental perforation on the oncological outcome. METHODS Using the Swedish Rectal Cancer Registry, patients were selected who received major abdominal surgery for rectal cancer between 1995 and 1997 with registered incidental perforation. A control group was also selected for analysis of the oncological outcome after 5-year follow-up. Multivariate analysis was performed. Registry data were validated, and additional data were supplemented from medical records. RESULTS After validation and exclusion of non-radically operated patients, 118 patients with incidental perforation and 155 controls in TNM stages I-III were included in the analysis. The rate of local recurrence (LR) [20% (23/118) vs. 8% (12/155) (p = 0.007)] was significantly higher among patients with perforation, whereas the rates of distant metastasis [27% (32/118) vs. 21% (33/155) (p = 0.33)] and overall recurrence (OAR) [35% (41/118) vs. 25% (38/155) (p = 0.087)] were not significantly different between the groups. Overall as well as cancer-specific 5-year survival rates were significantly reduced for the patients with perforation [44 vs. 64% (p = 0.002) and 66 vs. 80% (p = 0.026), respectively]. In the multivariate analysis, perforation was a significant risk factor of increased rates of LR and OAR as well as reduced 5-year overall and cancer-specific survival. CONCLUSIONS Incidental perforation in rectal cancer surgery is an important risk factor of poor oncological outcome and should be considered in the discussion concerning postoperative adjuvant treatment as well as the follow-up regime.

Abstract
This study focused on the impact of post-operative infection on patient outcome after resection with curative intent for colorectal cancer. Postoperative surgical and medical complications have been implicated as a negative predictor of long-term outcome in various malignancies. We studied a population of 1083 patients who underwent resection with curative intent for colorectal cancer. These patients were divided into 2 groups based on the occurrence (65 patients, 6%) or absence (1018 patients, 94%) of postoperative complications due to infection. We investigated the demographic and clinicopathological features of each patient with and without postoperative infectious complications, as well as the impact of postoperative infection on long-term survival. Results showed that patients with postoperative infectious complications had diabetes mellitus more frequently and also had urgent surgery compared to those without infectious complications. In addition, patients with postoperative infectious complications had a significantly more unfavorable outcome compared with those without postoperative infection in cancer-specific, but not overall survival. Multivariate analysis demonstrated that age, rectal cancer and tumor stage correlated with overall survival, but not postoperative infectious complications. However, postoperative infections, as well as gender, were associated with the length of time until the patient succumbed from the recurrence of colorectal cancer after resection for curative intent. Thus, postoperative infectious complications are predictors of adverse clinical outcome in patients with colorectal cancer. However, further immunological study is necessary to confirm the biological significance of these findings.

Abstract
BACKGROUND The prognostic significance of intraperitoneal tumour cells (IPCs) in colorectal cancer is not clear. This study aimed to determine whether detection of IPCs could be used a prognostic marker for selecting patients at high risk of recurrence. METHODS The study included 226 patients with colorectal cancer who underwent elective resection. Clinical variables, including the presence of IPCs, were analysed for their prognostic significance. RESULTS Thirty-three patients (14.6 per cent) were positive for IPCs. Univariable analysis indicated that the presence of IPCs was a significant prognostic factor in patients with stage III colorectal cancer; the 5-year disease-specific survival rate was 14 per cent in IPC-positive patients versus 79 per cent in those without IPCs (P < 0.001). Multivariable analysis showed that IPC positivity was the most robust prognostic factor in stage III disease (hazard ratio 2.2; P = 0.003), whereas nodal category (N1 or N2) showed no significant association with prognosis. In addition, IPCs were associated with haematogenous recurrence (P = 0.004) rather than peritoneal or local recurrence (P = 0.077) in patients with stage III disease. CONCLUSION The presence of IPCs is a significant prognostic factor in patients with stage III colorectal cancer.

Abstract
PURPOSE This study was designed to analyze the impact of anastomotic leak and intra-abdominal abscess on cancer recurrence and survival in patients who underwent resection for colorectal cancer. METHODS Data for patients who underwent resection for colon or rectal cancer were retrieved from a prospective colorectal cancer database. Patients with inflammatory bowel disease, familial adenomatous polyposis, hereditary nonpolyposis colorectal cancer, palliative resection, or perioperative mortality were excluded. Patients with postoperative anastomotic leak or intra-abdominal abscess were matched at a 1:2 ratio to patients from the same database who had no leak or abscess. Matched characteristics were age, gender, cancer stage, tumor histology, and operation occurring within three years of each other. Survival and cancer recurrence at five-year follow-up were evaluated with the Kaplan-Meier method and log rank test. RESULTS In patients with colon cancer, comparison of the 59 patients with a leak or an abscess with 118 matched controls showed no differences in demographic or treatment characteristics, recurrence, or mortality. In patients with rectal cancer, comparison of the 97 patients with a leak or an abscess with 194 matched controls showed that at five-year follow-up the complication group had higher rates of overall mortality (46.8 vs. 28.9, P < 0.01), cancer-specific mortality (28.7 percent vs. 18.0 percent, P = 0.03), overall recurrence (28.6 vs. 15.7, P = 0.01) and local recurrence (11.0 percent vs. 5.0 percent, P = 0.04). CONCLUSION Anastomotic leak and intra-abdominal abscess were not associated with worsened 5-year survival or recurrence in patients who underwent resection for colon cancer. However, these complications were associated with increased overall and cancer-specific mortality and increased overall and local recurrence in patients who underwent resection for rectal cancer.

Abstract
We describe the case of a left colon adenocarcinoma anastomotic recurrence that metastasized to a benign transsphincteric fistula-in-ano, presumably through the implantation of viable malignant cells shed from the secondary tumor, and discuss the implications of these findings in colorectal cancer surgery.

Abstract
BACKGROUND After total mesorectal excision (TME) for rectal cancer around 10% of patients develops local recurrences within the pelvis. One reason for recurrence might be spillage of cancer cells during surgery. This pilot study was conducted to investigate the incidence of remnant cancer cells in pelvic lavage after resection of rectal cancer. DNA from cells obtained by lavage, were analysed by denaturing capillary electrophoresis with respect to mutations in hotspots of the k-ras gene, which are frequently mutated in colorectal cancer. RESULTS Of the 237 rectal cancer patients analyzed, 19 had positive lavage fluid. There was a significant survival difference (p = 0.006) between patients with k-ras positive and negative lavage fluid. CONCLUSION Patients with k-ras mutated cells in the lavage immediately after surgery have a reduced life expectation. Detection of exfoliated cells in the abdominal cavity may be a useful diagnostic tool to improve the staging and eventually characterize patients who may benefit from aggressive multimodal treatment of rectal cancer.

Abstract
Povidone-iodine solution (Betadine) has long been accepted as an effective topical broad spectrum antiseptic, disinfectant, and tumoricidal agent. In colorectal operations, this solution generally has been used for the purpose of minimizing postoperative septic complications and reducing cancer recurrence, although the optimal application, advantages, and undesirable side effects have been debated. With limited prospective, randomized, controlled trials and insufficient data available, this article examines the safe and effective clinical applications of this solution for colorectal operations.

Abstract
We herein present a case of recurrence of gastric cancer in the jejunal pouch after total gastrectomy in a 74-year-old man. He had a history of two operations for gastric cancer. The second operation was a completion gastrectomy with jejunal pouch reconstruction and regional lymphadenectomy, for gastric cancer in the cardia of the remnant stomach, performed 2 years and 9 months before the present admission. A follow-up endoscopy showed three elevated tumors along the suture lines in the jejunal pouch in the upper digestive tract. Resection of the jejunal pouch was performed. Gross pathological examination revealed elevated lesions along the staple suture lines in the jejunal pouch. Histopathologically, moderately differentiated tubular adenocarcinoma involving the muscular layer, without lymphatic metastases, was recognized. Recurrence of gastric cancer in the jejunal pouch after resection is rare. We suggest that implantation of exfoliated cancer cells gave rise to the recurrence of tumors on the suture line in this patient. We also review two cases of gastric cancer in the jejunal pouch after resection previously described in the literature.

Abstract
BACKGROUND : Anastomotic leakage has a major impact on morbidity and mortality in rectal cancer surgery. Its relevance to oncological outcome is controversial. This observational study investigated the influence of anastomotic leakage on oncological outcome. METHODS : Data for 1741 patients undergoing curative resection of rectal cancer (located less than 12 cm from the anal verge) with normal healing were compared with those for 303 patients who experienced anastomotic leakage. Morbidity, mortality and long-term oncological outcomes were analysed. RESULTS : Median follow-up was 40 months. Patients with anastomotic leakage had a higher postoperative mortality rate than those with no leakage (4.3 versus 1.2 per cent; P < 0.001). Patients with leakage necessitating surgical treatment had a higher 5-year local recurrence rate (17.5 versus 10.1 per cent; P = 0.006) and a lower 5-year disease-free survival rate (70.9 versus 75.4 per cent; P = 0.020) than those without leakage. Patients with anastomotic leakage not requiring surgical intervention did not have a worse oncological outcome. CONCLUSION : A negative prognostic impact of anastomotic leakage on local recurrence and disease-free survival was found only for patients with leakage needing surgical revision.

Abstract
INTRODUÇÃO: A recidiva local no câncer colorretal tem como principal causa o implante de células tumorais nas anastomoses. 11-15 Dessa maneira, lavagem química do lúmen intestinal é preconizada para evitar tanto o implante quanto à recidiva local. 11-28 Em estudos prévios constatamos que a solução bicarbonatada de ácido acetilsalicílico tem efeitos citolíticos e anti-tumorais in-vitro.31 OBJETIVOS: Avaliar a toxicidade da solução de aspirina na mucosa colônica de coelhos com o objetivo de usá-la no preparo intestinal de portadores de câncer colorretal. MATERIAIS E MÉTODOS: Foram utilizados 20 coelhos. Um clampe vascular foi colocado acima do cólon sigmóide. Os animais foram submetidos a um enema com 50 ml da solução de aspirina ou soro fisiológico de acordo com o grupo. Os animais foram sacrificados ao término do procedimento ou tardiamente de acordo com o grupo. RESULTADOS: A solução de aspirina não altera a mucosa colônica de coelhos. CONCLUSÃO: O uso da solução bicarbonatada de ácido acetilsalicílico no preparo intestinal de portadores de câncer colorretal é clinicamente possível.

Can intra-operative intraperitoneal free cancer cell detection techniques identify patients at higher recurrence risk following curative colorectal cancer resection: a meta-analysis. Ann Surg Oncol 2007; 15:60-8.

Abstract
BACKGROUND Accurate staging of colorectal cancer is important for predicting prognosis and guiding treatment. This study uses meta-analysis to investigate if the pre- or post-resection detection of intraperitoneal free cancer cells can predict recurrence in patients undergoing curative colorectal cancer surgery. METHODS A literature search was performed on all studies between January 1990 and July 2007 comparing the detection of intraperitoneal free cancer cells either pre- or post-resection with prognosis in colorectal cancer. The following prognostic outcomes were meta-analyzed: overall recurrence rate and local recurrence rate. A random-effect model was used and heterogeneity was assessed. RESULTS Nine studies reporting on a total of 1182 subjects matched the selection criteria. Free cancer cells were detected prior to tumor resection in 125/822 (15.2%) of patients and following resection in 64/533 (12%) of patients. Preresection, the absence of tumor cells was associated with a lower overall recurrence (25.2%) compared to the presence of tumor cells [46.4%, odds ratio (OR) = 0.41, confidence interval (CI) 0.19-0.88]; as well as a significantly lower local recurrence (12.2% versus 21.1%, OR = 0.42, CI 0.21-0.82). Postresection, the absence of tumor cells also resulted in significantly lower overall recurrence (17.3%) when compared to the presence of tumor cells (52.6%, OR = 0.07, CI 0.03-0.18). CONCLUSIONS The detection of intraperitoneal free cancer cells is associated with higher recurrence and poorer prognosis. Use of these techniques can identify patients at higher recurrence risk. This could be particularly valuable in stage II disease to identify patients who may benefit from adjuvant chemotherapy.
