It is characterized by a cystic dilatation of the lumen with stasis of mucus inside it. Histopathologically mucocele is divided into three groups： focal or diffuse mucosal hyperplasia, mucinous cystadenoma and mucinous cystadenocarcinoma. This condition is often associated with other neoplasia, especially adenocarcinoma of the colon and ovaries. We here describe a 57 year old male patient who presented with abdominal discomfort, constipation, fresh blood in stool and frequent urination. He had a big cystadenoma of the appendix associated with adenocarcinoma of the colon and hepatocellular carcinoma of the liver. The patient underwent right haemicolectomy, sigmoid colon resection and segmental resection of the liven Now 3 years later he has no evidence of disease relapse. According to this, we stress the need of accurate preoperative diagnosis and intraoperative exploration of the whole abdomen in these patients.展开更多

METHODS: Resection of NCAPBT was performed in eight Chinese patients with complete clinical-pathological data in our hospital from January 2000 to May 2004. The surgical strategy was explored by analyzing the results of these patients. RESULTS: The resection rate of NCAPBT in patients without back pain was higher than that in patients with back pain (66.67% vs 20%, 2/3 vs 1/5). The prognosis in the group receiving palliative resection was poorer than that in the group receiving curative resection. The median survival time was 12 mo in the curative resection group and 6 mo in the palliative resection group, respectively. CONCLUSION: The overall survival time of the Chinese patients with NCAPBT is dismal. The Chinese patients after curative resection of NCAPBT have a longer survival time. The Chinese NCAPBT patients with back pain trend to have a lower curative resection rate, but back pain should not be considered a contraindication for curative resection.展开更多

Methods： This prospective comparative study included 91 consecutive patients who underwent LDP（n=45） or ODP（n=46） from Jan. 2010 to Dec. 2012. Demographics, intra-operative characteristics, and post-operative outcomes were compared. Results： The median operating time in the LDP group was（158.7±38.3） min compared with（92.2±24.1） min in the ODP group（P〈0.001）. Patients had lower blood loss in LDP than in the ODP（（122.6±61.1） ml vs.（203.1±84.8） ml, P〈0.001）. The rates of splenic conservation between the LDP and ODP groups were similar（53.3% vs. 47.8%, P=0.35）. All spleen-preserving distal pancreatectomies were conducted with vessel preservation. LDP also demonstrated better post-operative outcomes. The time to oral intake and normal daily activities was faster in the LDP group than in the ODP group（（1.6±0.5） d vs.（3.2±0.7） d, P〈0.01;（1.8±0.4） d vs.（2.1±0.6） d, P=0.02, respectively）, and the postoperative length of hospital stay in LDP was shorter than that in ODP（（7.9±3.8） d vs.（11.9±5.8） d, P=0.006）. No difference in tumor size（（4.7±3.2） cm vs.（4.5±1.8） cm, P=0.77） or overall pancreatic fistula rate（15.6% vs. 19.6%, P=0.62） was found between the groups, while the overall post-operative complication rate was lower in the LDP group（26.7% vs. 47.8%, P=0.04）. Conclusions： LDP is safe and effective for benign or premalignant pancreatic neoplasms, featuring lower blood loss and substantially faster recovery.展开更多
