ABSTRACT
Objective To explore selective criteria of sphincter preservation operation(SPO) for middle to low third rectal cancer,and analyze clinicopathologic parameters resulting in the selective criteria.Methods Two hundred and seventy-nine cases of middle to low third rectal cancer who accepted operative treatment from 1996 to 2004 were analyzed retrospectively.One hundred and eighty-seven rectal tumours were located in 5-10 cm from anus,92 rectal tumours in below 5 cm from anus.Among them 127 cases were treated by abdominal-perineal resection(APR),and 152 cases were treated by SPO in which there were 130 Dixon operations,12 Bacon operations,and 10 Parks operations.Clinicopathologic parameters and survival rate in APR and SPO groups were compared statistically.Results Gender,age,size,tumor types,site of tumor,degree of differentiation,infiltrated circumference of intestine,and lymph node metastasis,depth of invasion and Dukes stages were not significantly different between APR and SPO groups.SPO performed rate was 54.48% in all.SPO was performed in 48 lower third rectal cancer cases(52.17%,48/92).Regional recurrence rate was 6.81%(19/279).Middle survival time was((65.00?6.87))months and 5-year survival rate was 63.51% in SPO group.Middle survival time was((52.23?5.63)) months and 5-year survival rate was 52.50% in APR group.Chi-Suqare was 18.14 by Log-rank test(P=0.054 1).Conclusion There is no statistically difference in survival rate between APR and SPO groups.
ABSTRACT
Objective To summarize the methods of diagnosis and operation of carcinoma of the extrahepatic bile ducts. Methods The clinical data of 100 cases of carcinoma of the extrahepatic bile ducts which were treated in our hospital from 1972 to 1999 were retrospectively analysed. In this series, there were 68 cases of the cancer located in the upper portion of exlrahepatic duct(proximal cancer), 12 in midder portion(midder cancer), 18 in lower portion(distal cancer), and 2 in whole bile duct. Results The initial symptom was upper abdominal discomfort or vague pain, abdominal distension, weakness, weight loss and progressive jaundice. BUS, CT and MRI were scatheless. If the intrahepatic bile duct dilatation or extrahepatic cholestatic jaundice were revealed, PTC(13 cases in this series) or ERCP(42 cases in this series) were to further determine the location of tumor. According to the position and type of the tumor, the different operations were selected. Twenty-five cases(36.8%) of the proximal cancer were resected, including 15 cases of type Ⅰ treated with localresection or “skeletonization” resection, 9 cases of type Ⅱ treated with resection of the tumor and caudate lobe, 1 case of type Ⅲb treated with resection of the tumor, caudate lobe and left hepatic trisegmentectomy. Nine cases(75%) of midder cancer were resected. After resected the proximal and midder cancer, bile duct reconstruction by Roux-en-Y hepaticojejunostomy was performed on all the cases. Fourteen cases(77.8%) of distal cancer were treated by pancreatoduodenectomy. The total resection rate in this series was 48%. Of the cancer resected cases, 35 were followed up, the five-year survival rate was 58%. 32 of the 52 cases without cancer resection were followed up, and all of them died one to one and half year after operation. Conclusions BUS, CT and MRI are the first selective methods for early diagnosis of the carcinomas of extrahepatic bile duct. If needed, PTC or ERCP should be done because of these methods have more accurate diagnostic value. Surgical resection of the tumor is the only likelihood for effective treatment.
ABSTRACT
Objective To observe the clinical results of laparoscopic cholecystectomy(LC) combined with endoscopic Oddi sphincterotomy(EST) in treating cholecystolithiasis and choledocholithiasis.Methods The preoperative and postoperative clinical data of 20 cases that received LC & EST combined therapy for cholecystolithiasis and choledocholithiasis were analyzed retrospectively.Results The success rate was 95.0% ,with all the calculi removed completely;no complications occurred.The average hositpal stay was 7.5 days.Conclusions Combined LC & EST procedure is a safe and effective method to treat patients suffering from cholecystolithiasis and choledocholithiasis.
