ABSTRACT

Objective:To investigate the effect of transorally inserted anvil (OrVil TM) in patients with relapsed or denovo carcinoma at the esophagogastric junction. Methods:The clinical data of 60 patients who underwent radical intent resection for locally relapsed or denovo esophagogastric junction adenocarcinoma at Zhengzhou University Cancer Hospital from Jan 2011 to Jun 2021 were retrospectively analyzed. The patients were divided into two groups according to whether transorally inserted anvil was used. Twenty-six patients who had used the system were assigned to the experimental group. Thirty-four patients without transorally inserted anvil were set to control group.Results:The incisor distance of the experimental group was shorter than that of the control group [36(34-40)cm vs. 39(36-41)cm, Z=-4.948, P<0.05]. Operation time in experimental group was 177 (145-260) min, compared to control group of 172 (140-225) min ( Z=-0.735, P=0.463). Intraoperative blood loss was 200 (100-900) ml in the experimental group and 300 (100-800) ml in the control group ( Z=-1.244, P=0.213). Postoperative upper margin distance of the experimental group was (3.6±1.7) cm compared to control group of (1.8±1.1) cm ( t=-0.735, P<0.01). The positive rate of margin in the experimental group was 4% vs. 15% in the control group ( χ2=1.931, P=0.165). The length of postoperative hospital stay in the experimental group was (18.6±5.2) d vs. (20.5±4.7) d ( t=-1.455, P=0.151). Surgery-related complications developed in 19% in the experimental group vs. 27% in the control group ( P>0.05). Conclusion:The application of the transorally inserted anvil in the operation of patients with locally relapsed or denovo esophagogastric junction cancer after initial operation reduces the difficulty of operation and decreases the positive rate of margin.

ABSTRACT

Object:To investigate the impact of carbon nanoparticle tracing on the number of lymph nodes harvested in obese patients during radical gastrectomy for gastric cancer.Methods:Clinical data of 127 patients undergoing D 2 radical gastrectomy in the Affiliated Tumor Hospital of Zhengzhou University from Jan 2015 to Dec 2019 were retrospectively analyzed. According to whether the patients were injected with carbon nano particles during operation, they were divided into two groups: 64 patients without carbon nano particles during operation served as control group; 63 patients with carbon nano particles were included into experimental group. Results:The operation time of the control group was (160±31) min and that of the experimental group was (168±28) min ( t=-1.521, P=0.445). Intraoperative blood lose in the control group was (234±82) ml and that in the experimental group was (238±84) ml ( t=-0.295, P=0.846). The number of lymph nodes harvested in the first station, in the second station, the number of total lymph nodes and the number of lymph nodes with diameter <5 mm in the control group were less than those in the experimental group(10.4±3.8 vs. 24.5±10.6, t=-10.054),(6.6±2.8 vs. 16.8±7.3, t=-10.381),(17.1±6.4 vs. 41.2±17.6, t=-10.293),(3.9±2.5 vs. 21.2±9.1, t=-14.662) (all P<0.05), while the number of positive lymph nodes was not statistically different between the two groups all (5.9±6.2 vs. 4.2±3.4, t=-1.963, P>0.05). Black staining of lymph nodes in nano carbon group: 1 542 black stained lymph nodes were detected in the experimental group, the black staining rate of lymph nodes was 59.44% (1 542/2 594). Conclusion:Intraoperative application of carbon nanoparticles can significantly increase the number of harvested lymph nodes in obese (BMI≥25 kg/m 2) gastric cancer patients after radical resection.

ABSTRACT

Objective:To investigate the application value of one-stitch prophylactic ileostomy in late ileostomy closure.Methods:The prospective randomized control study was conducted. The clinicopathological data of 141 patients with rectal cancer who underwent low anterior resection combined with prophylactic ileostomy in the Affiliated Tumor Hospital of Zhengzhou University from January 2016 to July 2020 were selected. There were 127 patients being selected after excluding 14 cases who did not undergo ileostomy closure. Patients undergoing one-stitch prophylactic ileostomy were divided into observation group, and patients undergoing traditional ileostomy were divided into control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) surgical situations of ileostomy closure; (3) postoperative situations; (4) follow-up. Follow-up was conducted using outpatient examination and telephone interview once a month after low anterior resection combined with prophylactic ileostomy to detect complication and death of patients. The end point was at 3 months after ileostomy closure. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( P25, P75) or M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. Results:(1) Grouping situations of the enrolled patients: a total of 127 patients were selected for eligibility, aged from 31 to 83 years, with a median age of 64 years. Of 127 patients, there were 66 cases in observation group and 61 cases in control group. (2) Surgical situations of ileostomy closure: all patients from the two groups underwent ileostomy closure successfully. The incision length, operation time, volume of intraoperative blood loss, cases with abdominal adhesion degree as slight adhesion or obvious adhesion were 4.25 cm(4.00 cm, 5.00 cm), 48.00 minutes(33.75 minutes, 58.00 minutes), 30 mL(20 mL, 50 mL), 34, 32 of the observation group, versus 7.50 cm(7.00 cm, 8.50 cm), 70.00 minutes(57.00 minutes, 80.00 minutes), 30 mL(30 mL, 50 mL), 13, 48 of the control group, showing significant differences between the two groups ( Z=-9.549, -6.133, -2.758, χ2=12.405, P<0.05). (3) Postoperative situations: cases with incision infection of the observation group and the control group were 5 and 13, respectively, showing a significant difference between the two groups ( χ2=4.917, P<0.05). (4) Follow-up: all the 127 patients were followed up for 6-21 months, with a median follow-up time of 10 months. During the follow-up, 3 cases of the control group had postoperative incisional hernia and were cured after conservative treatment. None of patient had anastomotic leakage related complications or died during the follow-up. Conclusion:The one-stitch preventive ileostomy has the advantage of ileostomy closure, which can reduce the operation time, volume of intraoperative blood loss and shorten the incision length effectively, so as to reduce the incidence of postoperative incision infection related complications.

ABSTRACT

Objective:To investigate whether adjuvant chemotherapy could be beneficial for patients with pT1N1M0 (stage ⅠB) gastric cancer.Methods:From Jan 2010 to Dec 2016, 185 patients with pT1N1M0 gastric cancer who were surgically resected at Henan Cancer Hospital were retrospectively analyzed. The patients were divided into chemotherapy group ( n=100) and non chemotherapy group ( n=85). Results:For disease-free survival (DFS) analysis, univariate survival analysis showed that age, examined lymph nodes, vascular invasion, nerve invasion and adjuvant chemotherapy were associated with DFS (all P<0.05); multivariate analysis showed that lymph node resection ≥ 16 ( HR=0.363, 95% CI: 0.160-0.827, P=0.016), vascular invasion ( HR=4.117, 95% CI: 1.796-9.436, P=0.001) and postoperative chemotherapy ( HR=4.530, 95% CI: 1.932-10.622, P=0.001) were independent risk factors for DFS. For disease-specific survival (DSS) analysis, univariate survival analysis showed that lymph node resection, vascular invasion, nerve invasion and adjuvant chemotherapy were associated with DSS; multivariate analysis showed that lymph node resection ≥ 16 ( HR=0.344, 95% CI: 0.144-0.822, P=0.016), vascular invasion ( HR=5.113, 95% CI: 2.029-12.887, P=0.001) and postoperative chemotherapy ( HR=4.694, 95% CI: 1.854-11.888, P=0.001)were independent risk factors for DSS. According to examined lymph nodes and vascular invasion , pT1N1M0 patients were divided into three risk categories (high, medium and low). DFS and DSS were significantly different among the three risk groups (all P<0.001, respectively). Conclusion:pT1N1M0 gastric cancer patients are expected to benefit from adjuvant chemotherapy. Patients with less than 16 lymph nodes and vascular invasion may be particularly suitable for adjuvant chemotherapy.

ABSTRACT

Objective:To investigate the clinical significance of MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction.Methods:The clinical data of 73 patients with adenocarcinoma on the esophagogastric junction operated from Jul 2018 to Aug 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. All patients underwent MRI examination within one week before surgery. First, the T 2WI, diffusion-weighted imaging and dynamic enhanced images of each patient were carefully observed to define the tumor location, size, shape, signal and enhancement mode, then the distances between the upper edge of the tumor and the cardiac incisure on MRI dynamic enhancement were measured independently, and compared with the measured distance in surgical fresh specimens. Results:The mean location of tumor upper edge measured in MRI of 73 patients was (1.75±1.98)cm, while measured in the surgical specimen was (1.72±1.97)cm. There was no significant difference between the two groups ( t=0.572, P=0.569). The intraclass correlation efficient between the two groups was excellent (ICC=0.974, 95% CI: 0.959-0.984, P<0.01). Conclusion:The measurement result of tumor upper edge in MRI is basically consistent with that of surgical specimens. MRI can be used to locate the tumor upper edge for adenocarcinoma of esophagogastric junction before operation.

ABSTRACT

Objective:To investigate the effects of preoperative endoscopic mucosal injection of carbon nanoparticle tracer and intraoperative serosa injection of carbon nanoparticle tracer on the acquisition of lymph nodes in total gastrectomy for gastric cancer.Methods:The retrospective cohort study was conducted. The clinical data of 118 patients with gastric cancer who underwent total gastrectomy in the Affiliated Tumor Hospital of Zhengzhou University between May 2017 and April 2018 were collected. There were 79 males and 39 females, aged from 26 to 81 years, with an average age of 59 years. Of 118 patients, 56 patients undergoing preoperative endoscopic mucosal injection of carbon nanoparticle tracer were divided into observation group and 62 patients undergoing intraoperative serosa injection of carbon nanoparticle tracer were divided into control group. Observation indicators: the total number of lymph node dissected, the number of positive lymph node dissected, the number of lymph node dissected at the first station and the number of lymph node dissected at the second station. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent-sample t test. Measurement data with skewed distribution were represented as M (range), and comparison between groups was analyzed using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Results:The total number of lymph node dissected, the number of positive lymph node dissected, the number of lymph node dissected at the first station, the number of lymph node dissected at the second station of the observation group were 48±16, 3(range, 0-25), 26±9, 23±7, respectively. The above indicators of the control group were 41±13, 4(range, 0-28), 25±8, 16±5, respectively. There were significant differences in the total number of lymph node dissected and the number of lymph node dissected at the second station between the two groups ( t=2.494, 6.588, P<0.05), and there was no significant difference in the number of positive lymph node dissected and the number of lymph node dissected at the first station between the two groups ( Z=0.747, t=1.689, P>0.05). Conclusions:Carbon nanoparticle labeled lymph node staining using preoperative endoscopic mucosal injection of carbon nanoparticle tracer or intraoperative serosa injection of carbon nanoparticle tracer is safe and effective in total gastrectomy for gastric cancer. Compared with intraoperative serosa injection of carbon nanoparticle tracer, preoperative endoscopic mucosal injection of carbon nanoparticle tracer can increase the total number of lymph node dissected, especially the number of lymph node dissected at the second station of gastric cancer.

ABSTRACT

Objective:To evaluate the efficacy and perioperative safety of FLOT regimen in neoadjuvant chemotherapy for gastric adenocarcinoma.Methods:Data of 128 cases of neoadjuvant chemotherapy for gastric adenocarcinoma at the General Surgery Department of He′nan Cancer Hospital from Jan2018 to July 2019 were divided into FLOT group and SOX/XELOX group.Results:The disease control rate in the FLOT group was 81%, while that in the SOX/XELOX group was only 60% ( P=0.040). In terms of TRG classification and ypT staging, the proportion of TRG0 / 1 in the FLOT group was 49%, which was significantly higher than 21% in the SOX / XELOX group ( P=0.001). In the FLOT group, ypT 0-4 was 2, 10, 8, 17 and 6, respectively, while in the SOX/XELOX group, ypT 0-4 was 1, 9, 15, 26 and 34, respectively, ( P=0.022). In the FLOT group, ypTNM stages Ⅰ, Ⅱ, and Ⅲ were 11, 20, and 12, respectively, while in the SOX/XELOX group, ypTNM stages Ⅰ, Ⅱ, and Ⅲ were 12, 30, and 43, respectively ( P=0.040). Complications occurred in 10 patients (23%) in the FLOT group and 18 patients (21%) in the SOX/XELOX group ( P>0.05). Conclusions:FLOT neoadjuvant chemotherapy for advanced gastric adenocarcinoma does not increase the incidence of perioperative complications while effecting tumor regression and downstaging compared to SOX/XELOX regimen.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the technical advantages of nano carbon development combined with artery approach in lymph node sorting of rectal cancer.</p><p><b>METHODS</b>From December 2015 to June 2016, 70 patients with of rectal cancer in General Surgery Department of Henan Cancer Hospital were randomly divided into nano carbon development combined with artery approach group(artery approach group) and conventional group. Specimen of artery approach group was placed on the sorting table. Anatomy was performed from the root of inferior mesenteric artery to left colonic artery, sigmoid artery and superior rectal artery. Along the arterial vessel shape, the black-stained lymph nodes and non-stained lymph nodes (perhaps pink, pale yellow, white or pale brown) were examined carefully using visual and haptic combination method for identification of lymph node. From the root of inferior mesenteric artery, central lymph nodes were sorted. Along the vessel shape, vascular lymph nodes were sorted. Intestinal lymph nodes around the rectum were examined as well. Then, specimen was reversed on the sorting table and underwent sorting as above after the examination of obverse. The conventional group received routine method. The total number, the average harvested number, the number of positive lymph nodes and the number of patients with lymph nodes less than 12 were compared between two groups.</p><p><b>RESULTS</b>Among 70 cases, 37 were male and 33 were female with the median age of 57(32-88) years old. Dixon resection was performed in 46 cases, and Miles resection in 24 cases. Total sorting lymph node was 1 105, including 641 of artery approach group and 464 of control group with significant difference (t=20.717, P=0.000). Lymph node sorting time of artery approach group was (12.6±3.9) minutes, which was shorter than (18.2±4.1) minutes of control group (t=12.464, P=0.000). In artery approach group, number of lymph node with diameter less than 5 mm was 142, sorting rate was 22.2%(142/641), of which 29 were positive(20.4%). In conventional group, 37 lymph nodes with diameter less than 5 mm were found, and sorting rate was 8.0%(37/464), of which 6 were positive(16.2%).

ABSTRACT

<p><b>OBJECTIVE</b>To explore the application of three-stitch preventive transverse colostomy in anterior resection of low rectal cancer.</p><p><b>METHOD</b>From May 2015 to March 2016, 70 consecutive low rectal cancer patients undergoing anterior resection and preventive transverse colostomy in our department were recruited in this prospective study. According to the random number table method, 70 patients were divided into three-stitch transverse colostomy group(observation group, n=35) and traditional transverse colostomy group(control group, n=35). Procedure of three-stitch preventive transverse colostomy was as follows: firstly, at the upper 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from outside to inside, then the needle belt line went through the transverse edge of the mesangial avascular zone. At the lower 1/3 incision 0.5-1.0 cm distance from the skin, 7# silk was used to suture from inside to outside, then silk went through the transverse edge of the mesangial avascular zone again and was ligatured. Finally, in the upper and lower ends of the stoma, 7# silk was used to suture and fix transverse seromuscular layer and the skin. The operation time and morbidity of postoperative complications associated with colostomy were compared between two groups.</p><p><b>RESULTS</b>There were no significant differences in baseline data between the two groups(all P>0.05). The operative time of observation group was shorter than that of control group [(3.2±1.3) min vs. (15.5±3.4) min, P<0.05]. Incidences of colostomy skin-mucous separation, dermatitis, stoma rebound were significantly lower in observation group [5.7%(2/35) vs. 34.3%(12/35), P=0.007; 8.6%(3/35) vs. 31.4%(11/35), P=0.036; 0 vs. 17.1%(6/35), P=0.025, respectively], while incidences of parastomal hernia and stoma prolapse in two groups were similar (both P>0.05).</p><p><b>CONCLUSION</b>Compared with traditional transverse colostomy method, the three-stitch preventive transverse colostomy has more operating advantages and can reduce postoperative complications associated with colostomy.</p>

ABSTRACT

Background:Colonoscopy is difficult in elderly patients and is accompanied by more frequent abdominal pain and tissue injury. Aims:To investigate the impact of water infusion colonoscopy on abdominal pain and inflammatory response in elderly patients. Methods:Forty elderly patients requiring colonoscopy were enrolled from Jan. 2014 to Jun. 2016 at the Nanyang Second People’s Hospital and randomly allocated into two groups:colonoscopy with traditional air insufflation and colonoscopy with water infusion instead of air insufflation for cecal intubation. Times of cecal intubation and withdrawal were recorded;visual analogue scale( VAS)was used to assess the severity of abdominal pain;and serum levels of three inflammatory indices,tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and C-reactive protein(CRP)were determined by ELISA before and after the procedure. Results:VAS score at colonoscopy in water infusion group was significantly lower than that in air insufflation group(P﹤0. 05),however,times of cecal intubation and withdrawal were not significantly different between the two groups(P﹥0. 05). Before the procedure,serum levels of inflammatory indices were similar between air insufflation group and water infusion group(P﹥0. 05);0,6 and 24 hours after the procedure, serum levels of TNF-α,IL-6 and CRP in air insufflation group were significantly increased(P﹤0. 05)and higher than those in water infusion group at the same time points(P﹤0. 05). These inflammatory indices were recovered more rapidly in water infusion group than in air insufflation group. Conclusions:For elderly patients,colonoscopy with water infusion might ameliorate abdominal pain and inhibit systemic inflammatory response effectively.

Objective To explore the risk factors of ulcerative colitis-associated colorectal cancer (UC-CRC).Methods The retrospective case-control study was conducted.The clinicopathological data of 536 patients with ulcerative colitis (UC) who were admitted to the Henan Tumor Hospital from March 2004 to June 2015 were collected.Observation indicators:(1) follow-up results:cases with follow-up,follow-up time,cases of UC-CRC,age of onset,pathological type of UC-CRC;(2) risk factors analysis affecting occurrence of UC-CRC:gender,age of onset,course of disease,severity of disease,disease classification,extent of lesion,smoking history,family history of colorectal cancer,anemia,hypoproteinemia,body weight loss,extraintestinal manifestations,colonic polyps,backwash ileitis,atypical hyperplasia,anxiety or depression,treatment method and regular endoscopy reexamination.Follow-up using outpatient examination and telephone interview was performed to detect prognosis of patients up to April 2017.Patients underwent colonoscopy once every 6 months within 3 years after diagnosis and once every 1 year after 3 years.Measurement data with skewed distribution were described as M (range).The univariate analysis was done using the chi-square test and Fisher exact probability.The multivariate analysis was done using the Logistic regression model.Results (1) Follow-up results:of 536 patients,450 were followed up for 26.0-120.0 months,with a median time of 76.4 months.During the follow-up,16 patients were complicated with UC-CRC,including 9 males and 7 females.Age of onset of colorectal cancer was 14-78 years,with an average age of onset of 44 years.Pathological type:high-differentiated right colon adenocarcinoma was detected in 5 patients,high-and moderate-differentiated left colon adenocarcinoma in 3 patients,left colon signetring cell carcinoma in 2 patients,moderate-differentiated rectal tubular adenocarcinoma in 3 patients,highdifferentiated rectal papillary adenocarcinoma in 2 patients and malignant lymphoma in 1 patient.(2) Risk factors analysis affecting occurrence of UC-CRC:the results of univariate analysis showed that course of disease,extent of lesion,colonic polyps and atypical hyperplasia were risk factors affecting occurrence of UC-CRC (x2 =14.848,18.885,10.554,P<0.05).The results of multivariate analysis showed that course of disease > 10 years,lesion involving the whole colon,colonic polyps and atypical hyperplasia were independent risk factors affecting occurrence of UC-CRC (OR=12.893,17.847,7.326,19.742,95% confidence interval:1.726-74.337,1.445-89.793,1.263-43.128,3.625-96.524,P<0.05).Conclusion The course of disease > 10 years,lesion involving the whole colon,atypical hyperplasia and colonic polyps are independent risk factors affecting occurrence of UC-CRC.

ABSTRACT

Objective@#To study the predictive and prognostic significance of high-sensitivity modified Glasgow Prognostic Score (HS-mGPS) on the effect of neoadjuvant chemotherapy for advanced gastric cancer.@*Methods@#117 patients with advanced gastric cancer received neoadjuvant chemotherapy with SOX (oxaliplatin+ S1) or mFOLFOX 6(oxaliplatin+ CF+ 5-FU) regimen. HS-mGPS was calculated according to blood C-reactive protein (CRP) concentration and serum albumin (ALB) level. The correlation between HS-mGPS and clinicopathological characteristics was determined and the predictors of survival were analyzed.@*Results@#117 patients with stage ⅡB (43 cases), stage Ⅲ (60), and stage Ⅳ (14) received preoperative neoadjuvant chemotherapy. The overall response rate of neoadjuvant chemotherapy was 61.5%(72/117), and the tumor control rate was 88.0% (103/117), with a pathological response rate of 91.5% (107/117). The R0 resection rate was 81.2% (95/117). The median disease-free survival (DFS) was 21.0 (95% CI 6.4-35.6) months. The median overall survival (OS) was 39.0 (95% CI 21.4-56.6) months. Higher HS-mGPS was associated with higher T stage, local lymph-node metastasis, distant metastasis, lower chemotherapy overall response rate and lower pathological response rate (all P<0.05). The univariate analysis and multivariate analysis showed that higher HS-mGPS, presence of local lymph-node metastasis and non R0 resection were associated with poorer DFS and OS (P<0.05).@*Conclusion@#HS-mGPS can be used to predict the benefits of neoadjuvant chemotherapy and as an independent prognostic factor for survival in patients with advanced gastric cancer.
