ABSTRACT
Objective To compare the clinical effects of peritoneal cavity after laparoscopic renal pelvis and ureter lithotomy and traditional open renal pelvis incision nephrolithotomy.Methods 150 cases with renal pelvis and ureteral calculi were randomly divided into control group and observation group with 75 cases in each group,the control group was given traditional open pyelolithotomy for treatment while the observation group was given peritoneal cavity after laparoscopic renal pelvis and ureter lithotomy for treatment,clinical efficacy of the two groups were compared.Results The clinical effective rate of the observation group after treatment was 100％,which that of the control group was 92％,there was significant differences between the two groups (x2 =10.31,P ＜ 0.05).The operation time in the observation group was (90 ± 12) min,amount of bleeding during operation was (25 ± 7) mL,hospital stays was (10 ± 3) d,which were better than those of the control group,there were significant differences between the two groups (t =7.24,8.31,7.61,all P ＜ 0.05).Conclusion Retroperitoneal laparoscopic pyelolithotomy and ureterolithotomy is a minimally invasive operation,which has the advantages of definite curative effect,less trauma,less bleeding,rapid recovery,superior than the traditional open pyelolithotomy,so it is worthy of clinical application.
ABSTRACT
Owing to the introduction of national screening program, the detection rate of early gastric cancer (EGC) has been rapidly increased in Korea. Laparoscopic gastrectomy has been widely accepted as one of the standard treatments of EGC regardless of the risk of lymph node metastasis. Benefits of laparoscopic surgery included less pain, earlier recovery, lower complication rate than open surgery. Studies from Korean Laparoscopic Gastrointestinal Surgery Study Group (KLASS) reported short-term outcome including feasibility, safety, and effectiveness as well as satisfactory long-term oncologic outcome. Ongoing prospective randomized controlled trials for early and advanced gastric cancer patients designed by KLASS will provide the evidence of the role of laparoscopic surgery.
