Conclusions:With the increase of the operation volume of simultaneous resection of synchronous colorectal liver metastasis, the operation time, time to postoperative initial liquid food intake, postoperative duration of hospital stay and postoperative complications have significantly decreased, while the overall survival rate and disease free survival rate have significantly increased.

Objective:To investigate clinical efficacy of conformal sphincter preservation operation (CSPO) versus intersphincteric resection (ISR) in the treatment of low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 183 patients with low rectal cancer who were admitted to two medical centers (117 in the Changhai Hospital of Naval Medical University and 66 in the Huashan Hospital of Fudan University) from August 2011 to April 2020 were collected. There were 110 males and 73 females, aged (57±11)years. Of 183 patients, 117 cases undergoing CSPO were allocated into CSPO group, and 66 cases undergoing ISR were allocated into ISR group, respectively. Observation indicators: (1) surgical situations of patients with low rectal cancer in the two groups; (2) postoperative complications of patients with low rectal cancer in the two groups; (3) follow-up; (4) influencing factors for prognosis of patients with low rectal cancer; (5) influencing factors for satisfaction with the anal function of patients with low rectal cancer. Follow-up was conducted using outpatient examination, questionnaire and telephone interview to determine local recurrence, distal metastasis, survival, stomal closure, satisfaction with the anal function of patients. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test.The Kaplan-Meier method was used to draw survival curves, and life table method was used to calculate survival rates. Log-rank test was used for survival analysis. Univariate analysis was performed using the linear regression. Variables with P<0.10 in the univariate linear regression analysis were included for multivariate analysis. Multivariate analysis was performed using the COX stepwise regression model and linear regression analysis. Results:(1) Surgical situations of patients with low rectal cancer in the two groups: cases with laparoscopic surgery, operation time, volume of intraoperative blood loss, distance from tumor to distal margin, cases with postoperative chemotherapy, duration of postoperative hospital stay were 44, (165±54)minutes, (142±101)mL, (0.6±0.4)cm, 76, (6.6±2.5)days for the CSPO group, respectively, versus 55, (268±101)minutes, (91±85)mL, (1.9±0.6)cm, 9, (7.9±4.7)days for the ISR group, showing significant differences between the two groups ( χ2=35.531, t=8.995, -3.437, -3.088, χ2=44.681, t=2.267, P<0.05). (2) Postoperative complications of patients with low rectal cancer in the two groups: 19 patients in the CSPO group had complications. There were 6 cases with grade Ⅰ complications, 12 cases with grade Ⅱ complications, 1 case with grade Ⅲb complication. Fourteen patients in the ISR group had complications. There were 4 cases with grade Ⅰ complications, 7 cases with grade Ⅱ complications, 1 case with grade Ⅲa complication, 2 cases with grade Ⅲb complications. There was no significant difference in the postoperative complications between the two groups ( χ2=0.706, P>0.05). Patients with complications in the two groups were improved after symptomatic and supportive treatment. There was no perioperative death in the postoperative 30 days of the two groups. (3) Follow-up: 183 patients received follow-up. Patients of the CSPO group and ISR group were followed up for (41±27)months and (37±19)months, respectively, showing no significant difference between the two groups ( t=-1.104, P>0.05). There were 2 cases with local recurrence and 9 cases with distal metastasis of the CSPO group, respectively, versus 3 cases and 4 cases of the ISR group, showing no significant difference between the two groups ( χ2=1.277, 0.170, P>0.05). The 3-year disease-free survival rate and 3-year total survival rate were 84.0% and 99.0% for the CSPO group, versus 88.6% and 92.8% for the ISR group, showing no significant difference between the two groups ( χ2=0.218, 0.002, P>0.05). The stomal closure rate was 92.16%(94/102) and 96.97%(64/66) for 102 patients of CSPO group and 66 patients of ISR group up to postoperative 12 months,respectively, showing no significant difference between the two groups ( χ2=1.658, P>0.05). Of the 8 cases without stomal closure in the CSPO group, 2 cases refused due to advanced age, 4 cases subjectively refused, and 2 cases were irreducible due to scar caused by radiotherapy. Two cases in the ISR group had no stomal closure including 1 case of postoperative liver metastasis and 1 case of subjective refusal. There were 92 and 61 patients followed up to 12 months after stomal closure, of which 75 cases and 38 cases completed questionnaires of satisfaction with the anal function. The satisfaction score with the anal function was 6.8±2.8 and 5.4±3.0 for CSPO group and ISR group, respectively, showing a significant difference between the two groups ( t=-2.542, P<0.05). Fifty-four cases in the CSPO group and 21 cases in the ISR group had satisfaction score with the anal function >5, showing no significant difference between the two groups ( χ2=3.165, P>0.05). (4) Influencing factors for prognosis of patients with low rectal cancer: results of COX stepwise regression analysis showed that gender and pT staging were independent influencing factors for disease-free survival rate of patients with low rectal cancer ( hazard ratio=2.883, 1.963, 95% confidence interval as 1.090 to 7.622, 1.129 to 3.413, P<0.05). Gender and pT staging were independent influencing factors for total survival rate of patients with low rectal cancer ( hazard ratio=10.963,3.187, 95% confidence interval as 1.292 to 93.063, 1.240 to 8.188, P<0.05). (5) Influencing factors for satisfaction with the anal function of patients with low rectal cancer: results of univariate analysis showed that surgical method and tumor differentiation degree were related factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.464, -1.580, 95% confidence interval as 0.323 to 2.605, -2.950 to -0.209, P<0.05). Results of multivariate analysis showed that surgical method, tumor differentiation degree and preoperative radiotherapy were independent influencing factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.637, -1.456, -1.668, 95% confidence interval as 0.485 to 2.788, -2.796 to -0.116, -2.888 to -0.447, P<0.05). Conclusion:Compared with ISR, CSPO can safely preserve the anus in the treatment of low rectal cancer, without increasing the incidence of postoperative complications, which can also guarantee the oncological safety and improve the postoperative anal function.

Objective:This study aims to analyze the prognosis of patients who underwent a simultaneous operations for colorectal cancer and liver metastases, and to establish a prognostic scoring system for these patients.Methods:From January 2010 to March 2019, the clinicopathological data of patients with colorectal cancer and liver metastases simultaneously operated at Shanghai Changhai Hospital were collected. The clinicopathological prognostic factors on tumor recurrence and survival outcomes on follow-up were analyzed. Single and multiple factors Cox regression analyses were used to determine the risk factors which affected the prognosis of patients. Using the risk factors of poor prognosis on Cox analysis, 1 point was given to each risk factor. Patients were then divided into different groups according to the different total scores. The median overall survival and disease-free survival of each group were analyzed.Results:Of 234 patients included in this study, there were 126 males and 108 females. The average age was (57.4±10.8) years. The median survival was 44.85 months. The 1-, 3-, and 5-year survival rates of the whole group were 87.3%, 55.2%, and 22.9%, respectively. Primary tumor in right colon, preoperative carcinoembryonic antigen ≥200 ng/ml, multiple liver metastases, and poorly differentiated adenocarcinoma/mucinous adenocarcinoma were independent risk factors of poor prognosis. After 1 point was given to each of the above 4 items, patients were then divided into the low-risk (0-1) and high-risk (2-4) groups. The median survivals of patients in the low-risk group ( n=174) and high-risk group ( n=60) were 53 months and 29 months, respectively. The corresponding median disease-free survivals were 21.34 months and 8.48 months, respectively. The differences between the 2 groups were significant ( P<0.05). Conclusion:The results of this study preliminary established a predictive scoring system for patients with simultaneous colorectal cancer and liver which can play a role in selecting treatment options for these patients.

Objective To evaluate the efficiency and safety of full-spectrum endoscopy for detection of major duodenal papilla. Methods Patients underwent painless gastroscopy in Chinese PLA General Hospital from March 2017 to December 2017 were enrolled and randomly divided into two groups according to random number method. The group A underwent conventional gastroscopy, and the group B underwent full-spectrum endoscopy. The detection rate of major duodenal papilla was calculated and compared between the two groups. Results A total of 100 patients were recruited in the study, including 51 in the group A and 49 in the group B. The whole detection rate of major duodenal papilla of the group B was higher than that of the group A [79. 59％ (39/49) VS 41. 18％ (21/51), χ2 =15. 366, P=0. 000]. There was no statistical difference on the whole plus partial detection rate of major duodenal papilla between the two groups [100. 00％ (49/49) VS 92. 16％ (47/51), χ2=2. 221, P=0. 136]. All patients completed endoscopy examination succesfully without bleeding, peforation or death. Conclusion With the broad view-field, full-spectrum endoscopy is useful to improve the efficiency and safety in detection of major duodenal papilla.

OBJECTIVE: To investigate the surgical efficacy and prognostic factors of T3NxM0 middle-low rectal cancer without neoadjuvant therapy. METHODS: Clinical data of patients with middle-low rectal cancer undergoing TME surgery with T3NxM0 confirmed by postoperative pathology at Colorectal Surgery Department of Changhai Hospital from January 2008 to December 2010 were analyzed retrospectively. INCLUSION CRITERIA: (1)no preoperative neoadjuvant chemoradiotherapy (nCRT); (2) complete preoperative evaluation, including medical history, preoperative colonoscopy or digital examination, blood tumor marker examination, and imaging examination; (3) distance between tumor lower margin and anal verge was ≤ 10 cm; (4) negative circumferential resection margin (CRM-). Finally, a total of 331 patients were included in this study. According to the number of metastatic lymph node confirmed by postoperative pathology, the patients were divided into N0 group without regional lymph node metastasis (190 cases) and N+ group with regional lymph node metastasis (141 cases). The perioperative conditions, local recurrence, distant metastasis and prognostic factors were analyzed. RESULTS: Compared to N0 group in the perioperative data, N+ group had higher ratio of tumor deposit [29.8%(42/141) vs. 0, χ²=64.821, P<0.001] and vascular invasion [7.1%(10/141) vs. 0.5%(1/190),χ²=10.860, P<0.001]. There were no significant differences in tumor diameter, number of lymph nodes detected, positive nerve invasion, degree of tumor differentiation, morbidity of postoperative complication and postoperative adjuvant chemotherapy rate between the two groups (all P>0.05). The median follow-up period was 73.4 months. The merged 5-year local recurrence rate was 2.7%(9/331), 5-year distant metastasis rate was 23.3% (77/331), 5-year disease-free survival (DFS) rate was 73.4%, and 5-year overall survival (OS) rate was 77.2%. Multivariate analysis showed that lymph node metastasis (HR=3.120, 95%CI: 1.918 to 5.075, P<0.001), nerve invasion (HR=0.345, 95%CI: 0.156 to 0.760, P=0.008) and vascular invasion (HR=0.428, 95%CI: 0.189 to 0.972, P=0.043) were independent risk factors for DFS in patients with T3NxM0 rectal cancer after operation. Preoperative carcinoembryonic antigen level (HR=1.858, 95%CI:1.121 to 3.079, P=0.016), lymph node metastasis (HR=3.320, 95%CI: 1.985 to 5.553, P<0.001) and nerve invasion (HR=0.339, 95%CI: 0.156 to 0.738, P=0.006) were independent risk factors for OS in patients with T3NxM0 rectal cancer after operation. CONCLUSIONS Optimal local control rate of middle-low rectal cancer patients with T3NxM0 and CRM- can be achieved by standard TME surgery alone. For patients with preoperative elevated blood carcinoembryonic antigen level, regional lymph node metastasis, or neurovascular invasion confirmed by pathology after surgery, adjuvant chemoradiotherapy should be actively applied after surgery to improve prognosis.

OBJECTIVETo investigate the relationship between tumor regression grade (TRG) and lymph node regression grade (LRG) after neoadjuvant chemoradiotherapy (CRT) for rectal cancer and its clinical implication.

METHODSClinicopathological data of 176 rectal cancer patients undergoing radical excision after neoadjuvant CRT from January 2005 to December 2013 in our department were retrospectively analyzed.

INCLUSION CRITERIA(1) Radiology indicated locally advanced low rectal cancer and patients had strong desire to preserve the sphincter before neoadjuvant CRT; (2) there was no definite metastatic lesion before neoadjuvant CRT; (3) patients received whole course of neoadjuvant CRT (regular radiotherapy plus synchronous fluorouracil-like drugs chemotherapy); (4) patients underwent radical operation after neoadjuvant CRT. Patients with short-course CRT and emergency surgery were excluded. TRG and LRG of postoperative specimens (including tumor and lymph nodes) were carried out based on the percentage of the fibrosis and the cancer residue. No cancer residue was defined as TRG1 and LRG1; rare cancer cell residue as TRG2 and LRG2; fibrosis growth over residual cancer as TRG3 and LRG3; residual cancer growth over fibrosis as TRG4 and LRG4; absence of regressive changes as TRG5 and LRG5; and normal lymph nodes as LRG0. Spearman correlation test was used to assess the correlation between TRG and LRG.

RESULTSOf 176 patients, 111 were men and 65 were women. The mean age was (53.9±13.0) years. The number of patients with stage I(, II(, and III( before operation was 10, 49 and 62 while other 55 patients were unknown. Transabdominal low anterior resection (LAR) was performed in 118 cases and abdominal-perineal resection(APR) in 47 cases following the principle of total mesorectal excision (TME). Postoperative pathology of specimens revealed that the number of patients from TRG1 to TRG5 was 19 (10.8%), 25 (14.2%), 66 (37.5%), 47 (26.7%), 19 (10.8%), and from LRG0 to LRG5 was 35 (19.9%), 68 (38.6%), 10 (5.7%), 14 (8.0%), 15(8.5%), 34 (19.3%), respectively. TRG was correlated to LRG (P=0.005) while the Spearman correlation coefficient was only 0.24. The analysis of subgroup without LRG1 also showed that TRG was correlated to LRG(P=0.0005) and the Spearman correlation coefficient was 0.40.

CONCLUSIONSTRG can not represent LRG. Therefore, both TRG and LRG should be assessed when evaluating the response of rectal cancer to neoadjuvant CRT.

Objective To explore the clinicopathologic factors impacting recurrence and survival in rectal cancer patients after radical resection.Methods Clinicopathologic data of 1 166 patients with rectal cancer in Changhai Hospital,were recruited between 2005 and 2010.Kaplan-Meier analysis and the logrank test were used to evaluate the effects of the pathology on patients' survival.Cox regression model was used to assess independent factors associated with clinical prognosis.Results The 1,3,5-year overall survival rates were 94.3％,81.2％ and 76.5％,median survival time was 53 months.328 patients had recurrence and metastases,with a median recurrence time of 18 months.The independent prognostic factors for overall survival time were CEA,CA19-9,tumor distance to dentate line,surgical modality,radical operation,tumor invasion,tumor differentiation,lymph node metastasis and postoperative treatment.Surgical treatment,radical operation or not,tumor invasion and lymph node metastasis were statistically significant associated with tumor recurrence and metastases.Conclusions The important factors inffuencing the prognosis of rectal cancer patients were CEA,CA19-9,tumor distance to dentate line,surgical modality,radial operation,tumor in vasion,tumor differentiation,lymph node metastasis,and post operative treatment.
