Objective:To compare the clinical value of stent assisted intestinal bypass and temporary loop ileostomy in laparoscopic low anterior resection of rectal cancer.Method:In this retrospective analysis, 57 patients undergoing laparoscopic low anterior resection for rectal cancer in the First Affiliated Hospital of Ningbo University from Jan 2020 to Jan 2022 were divided into intestinal bypass group (36 cases) and loop ileostomy group (21 cases).Result:There were no significant differences in postoperative GI function recovery and postoperative complication rate between the two groups (all P>0.05). The levels of albumin, prealbumin and hemoglobin in the intestinal bypass group were better than those in the ileostomy group when evaluated on 3rd months after operation [(40.5±2.3) g/L vs. (38.1±2.6)g/L、(26.4±2.7)mg/dl vs. (24.5±2.0)mg/dl、(137.6±5.9) g/L vs. (134.0±7.0) g/L, t=3.605、2.743、2.085, all P<0.05]. Hospital expenses of the intestinal bypass group was lower [(571 000±7 500) yuan vs. (69 300±9 100) yuan, t=-5.477, P<0.05]. Conclusion:Compared with traditional ileostomy, the stent assisted intestinal bypass reduces trauma with lower expenses and improves patients' status after laparoscopic low anterior resection for rectal cancer.

Objective To explore the feasibility and clinical efficacy of serosal muscular layers incision and submucosal layers exfoliation technique in laparoscopic surgery for gastric gastrointestinal stromal tumors(GIST).Methods 28 patients with gastric GIST underwent serosal muscular layers incision and submucosal layers exfoliation technique under laparoscopic surgery.Patients' clinicopathologic characteristics,operative outcomes,postoperative complications,and follow up results were analyzed retrospectively.Results Surgery was successfully completed in all patients,and no one was converted to open surgery.The average operation time was (66 ± 15) min,and the intra operative blood loss was (16 ± 10) ml,the time of passage of gas by anus after operation was (20 ± 10)h,the time starting liquid diet was (2.5 ± 1.6) d,and the length of postoperative hospital stay was (7 ± 3) d.One patient had delayed gastric emptying,one had incisional infection.All the specimen had complete pseudocapsule and negative margin.pathology was all gastric GIST.After a median 22 months followed up,no recurrence or metastasis were found.Conclusion Serosal muscular layers incision and submucosal layers exfoliation under laparoscopic surgery is a safe and feasible procedure for treating gastric GIST.

Objective To investigate the application value of secondary splenic pedicle separation technology through superior posterior approach of the pancreatic tail in laparoscopic partial splenectomy.Methods The retrospective cross-sectional study was conducted.The clinicopathological data of 13 patients who underwent laparoscopic partial splenectomy in the Ningbo First Hospital from March 2016 to October 2017 were collected.After preoperative assessment using computed tomography(CT) angiography,13 patients underwent laparoscopic partial splenectomy using secondary splenic pedicle separation technology through superior posterior approach of the pancrcatic tail.Observation indicators:(1) intra-and post-operative recovery situations;(2) follow-up situations.Follow-up using outpatient examination was performed to detect postoperative changes of peripheral blood platelet (PLT),thrombosis of splenic vein,lesions residual or recurrence up to November 2017.Measurement data were represented as average (range).Results (1) Intra-and post-operative recovery situations:13 patients underwent successful laparoscopic partial splenectomy using secondary splenic pedicle separation technology through superior posterior approach of the pancreatic tail,without conversion to open surgery,including 6 with laparoscopic partial splenectomy of inferior pole of the spleen and 7 with laparoscopic partial splenectomy of upper pole of the spleen.Operation time was 42-93 minutes,with an average of 61 minutes;volume of intraoperative blood loss was 30-260 mL,with an average of 92 mL;postoperative gastrointestinal function recovery time was 22-47 hours,with an average of 34 hours;postoperative drainage tube removal time was 3.0-6.0 days,with an average of 4.2 days.The postoperative pathological examination of 13 patients:7,2,2,1 and 1 patients were respectively confirmed with splenic cysts,splenic hemangiomas,vascular hemangiomas,splenic hamartoma and splenic lymphangioma.Of 13 patients,1 was complicated with splenic recess effusion and fever,and was improved with B ultrasound-guided percutaneous catheter drainage.Duration of hospital stay of 13 patients was 7.0-16.0 days,with an average of 9.6 days.(2) Follow-up situations:13 patients were followed up for 1.0-19.5 months,with a median time of 8.5 months.During the follow-up,PLT level of 13 patients was normal.Color Doppler ultrasound examination showed no venous embolism,and CT angiography showed good vascular perfusion.There was no recurrence of splenic cysts in 7 patients and no tumor residual or recurrence in 6 patients.Conclusion Laparoscopic partial splenectomy using secondary splenic pedicle separation technology through superior posterior approach of the pancreatic tail is safe and effective,and it can precisely dissect splenic hilum,preserve blood supply and function of the remnant spleen,and reduce surgical injury.

Objective To evaluate circulating tumor cells (CTC) in prognosis prediction of gastric cancer.Method Peripheral blood samples were obtained from 65 patients with gastric cancer and 20 normal volunteers.CTC were detected by using CellSearch(R) CTC Detecting System.Postoperative progress-free survival (PFIS) and overall survival (OS) were evaluated against CTC status and clinicopathological factors.Result CTC were positive in 35 out of 65 (53%) patients compared to 1 out of 20 (5%) healthy controls,P < 0.05.CTC were not statistically corelated with patients' age,sex and lymph node status or distal metastasis,vascular invasion and tumor markers (all P > 0.05).CTC positive patients had poorer OS (P < 0.05) and PFS (P < 0.05) compared with those with negative CTC.Conclusion Positive CTC in gastric cancer patients predict poor prognosis after radical gastrectomy.

Objective To study the value of spiral CT in diagnosing renal cell carcinoma(RCC) and to evaluate the correlation of CT findings with histopathologie features in RCC. Methods 279 cases with RCC proven by surgery and pathology underwent plain and contrast-enhanced CT examinations. The clinic characteristics and CT findings were analyzed statistically and compared with surgical results. Results 90.32% lesions showed medium or obvious enhancement on contrast-enhanced CT,with the exception of granule cells for enhanced uniform, the other cell type of RCC showed heterogeneous enhancement. 32.26% of tumors was of more or less short-burres (χ~2 = 38.2,P<0.01) ,and the there was significant relationship between pathological signs of short burr and the renal capsule involved by tumors. CT qualitative diagnostic rate was 91.40%. CT staging and pathologic staging were of the correla-tive coefficient of 0. 84, while there was not obviously correlation between CT classification of RCC and cancer cell types(P>0.05). Conclusion Spiral CT can better show characteristics of RCC, that can improve the diagnostic accuracy and staging aility for RCC.
