Objective To study the effect of different family nursing methods on major catheter-re-lated complications in cancer patients with peripherally inserted central catheter (PICC) during chemother-apy intermission so as to reduce the incidence of complications and prolong the indwelling time and service life of the catheter. Methods We randomly divided 213 cancer patients who were discharged from hos-pital with PICC into two groups. One group(108 cases) routinely came back to our outpatient clinic and the other (105 cases) went to the community for nursing of the catheter. Results The total incidence rate of complications of the group who came back to our outpatient clinic for nursing of the catheter was 13.8%(15/ 108) and the other group was 51.4%(54/105). There existed statistical significance between the two groups (P<0.01). Conclusions There exists correlation between different family nursing methods and catheter complication rate. We suggest patients come back to our outpatient clinic for nursing of the catheter as pos-sible as they can.

Objective To investigate the surgical treatment and indications for primary lesion in patients with stage Ⅳ rectal cancer.nethods Clinical data of 118 patients with stage Ⅳ rectal cancer undergoing surgical treatment from January 1988 to December 2005 in Cancer Hospital of Chinese Academy of Medical Sciences were analyzed retrospectively using Statistical Package for the Social Sciences(Release 13.0,SPSS,Inc).Survival was estimated using the Kaplan-Meier method and compared using the log-rank test.Cox regression was used in multivariate analysis.Results One hundred and five of 118 patients received rectal primary lesion resection,including 16 cases with simultaneously metastatic tumor resection.13 of 118 patients received ostomy.The overall 5-year survival rate of the primary lesion resection group was 8.57%,the 5-year survival rate of the metastatic tumor resection group was 31.2%.The median survival in the primary lesion resection group and the ostomy group was 15 months and 13 months respectively(X2=0.736.P=0.778).Multivariate analysis showed that degree of differentiation of primary tumor,maximal diameter of liver metastasis and chemotherapy were the most important prognostic factor of the primary tumor resection group.Conclusion Simultaneous resection of primary and metastatic tumor can prolong suivival time of patients with resectable stage Ⅳ rectal cancer.

Objective To evaluate the diagnosis and treatment of duodenal neuroendocrine tumors.Method We retrospectively analyzed data of 15 patients with duodenal neuroendocrine tumors admitted between August 1999 and July 2012.Result In all the 15 cases accurate and definitive diagnosis were achieved via pathological examination and immunohistochemistry.Clinical diagnostic methods included ultrasound,endoscopy,upper gastrointestinal imaging,abdominal CT,MRI,etc.7 cases underwent pancreaticoduodenectomy,2 cases were treated by local excision,4 cases by endoscopic excision,and total gastrectomy and distal gastrectomy was performed in one each case.Conclusions The diagnosis of duodenal neuroendocrine tumors is established mainly by endoscopy and diagnostic imaging.Surgical resection is the treatment of choice.Pancreatoduodenectomy and local excision is applicable for G2 and G3 patients while endoscopic excision can be used for G1 patients.

Objective To investigate the relationship between clinicopathological characteristics and lymph node metastasis for carcinoma of the ampulla and papilla of Vater. Methods In this study, 152 patients with carcinoma of the ampulla and papilla of Vater underwent radical duodenopancreatectomy. Lymph node metastasis was correlated with clinicopathological factors. Results The rate of lymph node metastasis was 31%, that for T1,T2 ,T3, and T4 was 0, 20% (11/54) , 26% (19/72) , and 94% (16/17) , respectively, x2 analysis revealed that lymph node metastasis was associated with tumor size (

Objective To investigate the clinical and pathologic characteristics of rectal gastrointestinal stromal tumor (GIST),and to evaluate the management of rectal GIST. Methods The clinical and pathological data of 19 cases of rectal GIST in recent 19 years were studied retrospectively. Results The diagnosis of 19 cases of rectal GIST were identified by surgery and pathology. Most rectal GISTs were spindle cell type. Immunohistochemical analysis displayed positive reactivity for CD117(100%) and CD34(73. 7% ). Graded by aggressive behavior there were 4 cases of high risk, 3 cases of intermediate risk, 5 cases of low risk and 7 cases of very low risk. Conclusions Rectal GISTs have a low prevalence and have no specific symptom in the early stage. Most tumors are low risk in aggressive behavior. It is difficult to get an accurate pathological diagnosis before operation and difficult to decide whether a sphincter preserving procedure is justified however trans-anal local resection is the therapy of choice for low risk submucosal rectal GIST(

OBJECTIVETo study the application of hand-assisted laparoscopic surgery (HALS) in colorectal carcinoma resection.

METHODSFourteen patients with colorectal carcinoma underwent resection by HALS.

RESULTSHand-assisted laparoscopic right hemicolectomy was performed in 6 of 8 ascending colon cancer patients, spending an average of 160 minutes (110 to 220 minutes) for the procedure. The amount of bleeding was 40 approximately 100 ml. Bowel sounds resumed in 36 approximately 72 hours after the operation. The average interval between the operation and patients' discharge was 8 days (7 to 12 days). For 2 patients the surgeons had to resort to laparotomy. All patients received postoperative chemotherapy. Hand-assisted laparoscopic abdominoperineal resection was performed in 5 of 6 patients with lower rectal cancer, with the average duration of 180 minutes (120 to 270 minutes), with bleeding of 40 to 80 ml. Bowel sounds resumed within 24 to 72 hours and the average discharge interval was 14 days (12 to 18 days). The urinary catheter in 6 patients was removed in 7 to 8 days after the operation. All patients with rectal carcinoma received postoperative chemotherapy and radiotherapy. One patient was shifted to laparotomy because of extensive adhesion in the pelvic cavity. Four of 11 patients treated by HALS experienced slight pain in the incision. No other complications were observed in any of the patients. Remote results await further follow-up.

CONCLUSIONHand-assisted laparoscopic surgery in the treatment of colorectal carcinoma, a safe and simple procedure, not only ensures the clearance of tumor, but also reduces operative trauma and hastens recovery.
