Objective:To explore the drug application in the postoperative chemotherapy for the patients with non-small cell lung cancer. Methods:The chemotherapy regimens, drug utilization and adverse drug reactions in the non-small cell lung cancer patients received postoperative chemotherapy in 2012 were statistically analyzed in a retrospective study. Results:Totally 8 kinds of chemother-apy regimens were used in 156 cases. The NC( vinorelbine + carboplatin) regimen was used most frequently and the PC( pemetrexed+ carboplatin) regimen was with the highest expense. Proton pump inhibitors, recombinant human erythropoietin and lentinan were the top three in the adjuvant drugs used in the treatment. Conclusion:It is necessary to further standardize the postoperative chemo-therapy for non-small cell lung cancer patients. Thoracic surgeons along with pharmacists should strengthen the drug use monitoring during the whole treatment process to promote the rational drug use.

Objective To report a new approach of splenic hilar lymph nodes dissection in radical gastrectomy for gastric cancer. Methods 193 cases of gastric cancer patient receiving radical resection of gastric cancer between May 2008 and October 2008 were studied. The tail and body of spleen and pancreas were thoroughly freed with retroperitoneal way retrogressively and extruded out of abdominal cavity in 80 cases. The other 113 cases received operation with routine way. Results In 80 cases who received operation with retroperitoneal approach retrogressively, the total splenic hilar lymph nodes were 519, the positive ones were 65, the positive rate was 12.5 %; In the other 113 cases the total splenic hilar lymph nodes were 565, the positive ones were 58, the positive rate was 10.3 %. The positive rate had statistic significance between these two groups. Conclusion Extruded splenic hilar lymph nodes dissection with retroperitoneal approach retrogressively is safe and has the same effect with splenectomy in gastric cancer operation.

Objective To study the factors influencing the recurrence of aggressive fibromatosis(AF) patients.Methods Analyze clinical features and find out factors affecting AF recurrence with univariate and multivariate analysis. Results One hundred and three AF patients were analyzed. Diameter of all the masses was (7.84?5.62)cm. 98.2% of all patients received surgery and radical resection rate is 79.4%. First recurrent time after surgery of male and female is (1563?377) and (2117?3704) days for male and female cases respectively,it's (2723?461),(657?262),(2090?499),(812?220) and (721?234) days for that of abdomen wall、head and neck(H & N),deep mass,joints and chest wall. Recurrent time is (2232?271) and (1347?267) days for those with or without surgery history patients. Univariate analysis showed that gender,tumor site and surgery history of tumor site are prognostic factors of tumor recurrence. Multivariate analysis suggest that only surgery history of tumor site is an independant prognostic factors of AF recurrence after surgery. Conclusion Gender,tumor location and surgery history of tumor site can be valuable to predict postsurgery recurrence of AF.

Objective To explore the clinical outcome of using modified great toe wrap-around flap to reconstruct degloved thumb and fingers.Methods Eighteen patients were involved.Based on different types of injury,four procedures were carried on for reconstructing degloved thumb and fingers:①Unilateral modified great toe wrap-around flap to reconstruct 9 degloved thumbs of distal proximal level and 3 degloved fingers of proximal interphalangeal joint level.②Unilateral modified great toe wrap-around flap with second toe medial flap to reconstruct 2 total degloved fingers.③Bilateral modified great toe wrap-around flap to reconstruct 2 thumbs.④Bilateral modified great toe wrap-around flap and second toe medial flap with neurolized super thin anterolateral thigh flap to reconstruct 12 degloved fingers.This wrap-around flap carried with entire nail.A triangle flap was reserved at medial plantar of great toe.Results All free flaps were survived in one stage.Fifteen patients were followed up for 8 to 25 months.The contour of reconstructed digit was as same as contralateral digit with satisfactory motion arc and sensation.There was no extensive scar in donor toe.The width of medial plantar triangle flap increased significantly.All patients could walking,running,jumping without restricted.Conclusions With reconstructed by modified great toe wrap-around flap,degloved thumb or finger can be promised with excellent contour and function outcome.In the meantime,the loss of donor foot can be expected to minimal.This procedure is one of the best ways for reconstructing degloved thumb and finger.

Objective:To retrospectively analyze related factors of subtype transformation and to identify prognostic factors for pa-tients with retroperitoneal liposarcoma (RPLS). Methods:This study retrospectively analyzed the clinical data of 92 patients with RPLS, which were confirmed by postoperative pathology from July 1997 to October 2014 in Henan Provincial Tumor Hospital. Related studies were reviewed, and the prognoses were followed up. The factors may affect subtype transformation or prognoses were applied to the statistical analysis. Results:A total of 74 patients with RPLS were included according to the recruiting standard. The 5-year survival rate was 48.65%. Lobulated tumors (P=0.013) were the correlative factors that influenced subtype transformation. The Log-rank test showed that the age at diagnosis (P=0.045), multi-visceral resection (P=0.042), tumor necrosis (P<0.001), subtype transformation (P<0.001), and malignant level of pathological subtypes of the first operation (P<0.001) influenced overall survival. Multivariate Cox re-gression analysis showed that tumor necrosis and the malignant level of the initial histological grade were independent factors of over-all survival. Conclusion:Lobulated tumors are likely to transform the subtype. The prognosis of patients with RPLS is correlated with multi-visceral resection, tumors necrosis, subtype transformation, and the malignant level of pathological subtypes of the first opera-tion. Multi-visceral resection could not improve the 5-year survival rate of RPLS, and adjuvant therapy could not improve the prognosis.

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.

Objective To investigate the application value of the curved cutter stapler device combined with trans-orally inserted anvil (OrVil) in the radical resection of Siewert type Ⅱ adenocarcinoma of the esophagogastric junction (AEG).Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 206 patients with Siewert type Ⅱ AEG who were admitted to the Henan Tumor Hospital between March 2011 and March 2016 were collected.All the 206 patients underwent radical resection and 3-step clock wise total gastrectomy + D2 lymph node dissection.Observation indicators:(1) surgery and postoperative recovery situations:surgical approach,overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation,postoperative complications and duration of postoperative hospital stay;(2) postoperative pathological examination and chemotherapy;(3) follow-up and survival situations.Follow-up using telephone interview and outpatient examination was performed to detect tumor-free survival of patients up to April 2016.Measurement data with normal distribution were represented as x±s.The survival rate was calculated by the Kaplan-Meier method.Results (1) Surgery and postoperative recovery situations:all the 206 patients received successful operations,including 85 with abdominal operation,50 with abdominal incision through the diaphragmatic muscle into thoracic surgery and 71 with thoracic-abdominal surgery.Overall operation time,hammer anvil placing time,esophagojejunal anastomosis time,volume of intraoperative blood loss,number of lymph node dissected,time to anal exsufflation and duration of hospital stay were (113.7± 15.4)minutes,(3.5± 1.2)minutes,(10.4±2.9)minutes,(128±25) mL,32± 6,(2.4 ± 0.9) days and (12.3 ± 1.9) days,respectively.Of 206 patients,15 with postoperative complications were cured by conservative treatment,including 6 with implicit anastomotic fistula,3 with dominant anastomotic fistula,2 with pancreatic leakage,2 with intestinal obstruction,1 with anastomotic stenosis and 1 with thoracic and abdominal infection.There was no reoperation due to perioperative complications.(2) Postoperative pathological examination and chemotherapy:postoperative pathological results showed that distance from resection margin of the esophagus to tumor was (5.2±0.4) cm,without cancer cells in the resection margin.Among 206 patients,171 received postoperative chemotherapy by S1 single agent combined with oxaliplatin for 6-8 cycles or oral S1 single agent for 1 year.(3) Follow-up and survival situations:206 patients were followed up for (2.7± 0.3)years,with a tumor-free 3-year survival rate of 58％.During the follow-up,there was no recurrent anastomotic tumor.Conclusion The curved cutter stapler device combined with OrVil in the radical resection of Siewert type Ⅱ AEG can simplify the difficulty of esophagojejunal anastomosis and guarantee the safe resection margin of the lower esophagus.

Objective To evaluate the result of early repair for urinary fistula caused by iatrogenic injury to ureter,bladder and urethra during resection of rectal cancer.Methods We retrospectively analyzed 26 cases of urinary fistula after resection of rectal cancer patients encountered in Department of General Surgery,Henan Tumor Hospital from October 2005 to May 2016.Urinary fistula was divided into four types according to the site of fistula.Results Surgery was performed ever after the diagnosis of the fistula was identified.In type Ⅰ fistula (6 cases of posterior urethral fistula) the treatment was stent placement and packing of the greater omentum.2 cases of bladder top fistula (type Ⅱ),were treated by fistula repair and cystostomy.Type Ⅲ involved 12 cases (bladder triangle fistula).The treatment was ureter stenting replantation,and cystostomy Type Ⅳ:ureteral fistula in 6 cases,the treatment was end-to-end anastomosis and stenting.After surgery 24 cases were cured and 2 cases (all of type Ⅲ fistula) ended up with permanent bilateral ureterocutaneostomy.Conclusion It is safe and effective to make early remedy repair for ureter,bladder and urethral fistula iatrogenically during rectal cancer resection.

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.
