Objective To evaluate the safety and feasibility of LC in patients with acute cholecystitis. Methods The authors retrospectively analyzed 145 cases of acute cholecystitis treated by LC from 1992～2000. Results All cases were successfully treated by LC, durations of operations being 30 to 130min with a mean 68min. Postoperative complications were found in 5 cases: Two patients underwent cystic artery bleeding, which was stopped successfully via laparoscope; the other three patients had bile leakage, bleeding of the greater omentum and subhepatic abscess, respectively, the first two cases being dealt with by open operations and the later by anti-inflammatory therapy. The success rate of LC was 96 6% (140 of 145). Conclusions LC may be applied successfully to the patients with acute cholecystitis within the first three days of incidence, after the gallbladder wall is proved ≤ 5mm by B-ultrasonography.

Objective To analyze the clinical diagnosis and treatment of recurrent cancer in gastric remnant.Methods Clinical data of 48 patients who underwent surgical re-operation because of recurrent carcinoma within gastric remnant after radical resection of gastric cancer were analyzed retrospectively.Results All 48 cases were recurrent cancer in gastric stump.The time of recurrence was 6-36 months after first radical resection.After reoperation,the mean survival time of 28 patients(58.3%)who underwent radical resection was 40 months;the mean survival time of 20 patients(41.7%)who received palliative treatment was 14.8 months(P

Objective To study the causes of local recurrence,and diagnosis and treatment outcome of recurrent colorectal cancer.Methods The clinical data of 60 patients with recurrent colorectal cancer treated during 10 years in our hospital were analyzed retrospectively.Results Among the 60 cases,40 cases(66.7 %) had recurrence within 2 years after operation.Recurrence in anastomotic stoma,perineum,abdominal incision occurred and in the abdominal cavity and pelvic cavity in 15,10,7 and 20 cases respectively,and liver metastases were found in 8 cases.All patients underwent reoperation including curative surgery for 38 patients and palliative operation for 22 patients.After radical reoperation the 1-,3-,and 5-year survival rate was 93.6 %,48.8 %,and 36.3 %,respectively,and after palliative reoperation was 54.5 %,0 %,and 0 %,respectively.Conclusions Emphasizing the application of no-tumor touch technique,resection of adequate amount of bowel,performing complete lymphadenectomy and removal of micrometastatic lesions are the major measures to prevent recurrence of rectal cancer after operation.Integrative therapy regimens,of which surgical treatment is the major component,should be considered according to the location of recurrence and the clinical staging of the recurrent cases.
