ABSTRACT
Seven cases of renal tumor treated at our hospital from May 2009 to November 2011 were assigned to undergo laparoscopic ultrasonography assisted laparoscopic partial nephreetomy.The mean operative duration was 109 minutes (range:102-121).And the mean volume of blood loss was 82 ml (range:60-120).All patients had confirmed negative margins.Renal clear cell carcinoma was definitely diagnosed in all cases.Laparoscopic ultrasonography could provide more precise information of renal tumor within renal capsule.Thus it may be used to guide the operation so that tumors are excised more completely,residual tumor tissues avoided and normal renal tissues protected.
ABSTRACT
Objective To compare the effects of laparoscopy and open surgery of ligation of spermatic vessel cluster or internal spermatic vein for the treatment of varicocele.Methods By using randomized controlled trial,120 cases with varicocele who stayed and were treated in our hospital were divided into 4 groups(30 cases every group) from Jun.2007 to Oct.2011.The efficacy of 4 groups was observed and compared.Results Four operations were performed successfully.Laparoscopy approached less than open surgery in terms of the days of stay in hospital (P ＜ 0.05).The quality of semen in four groups was all increased by comparing spermatozoa density,motility rate before and after operation(P ＜ 0.05),but no difference was found among four groups (P ＞ 0.05).In 0.5-1 year follow-up,follow-up rate was 92.5％,without atrophy of testes.Conclusion The operation of laparoscopic spermatie vessel cluster ligation in patients with varicoceh has the advantage of confirmed effect,which is an alternative operative method of treatment for patients with varicocele.
ABSTRACT
Objective To explore the feasibility of fishing net repairing transverse fascia method for inguinal hernia (type Ⅰ , Ⅱ ) using laparoscopic surgical procedure. Methods A retrospective analysis of clinical data between the method of fishing net repairing transverse fascia surgery for 145 cases of inguinal hernia (typeⅠ,Ⅱ ) using laparoscopic surgical procedure from May 2004 to May 2008 (laparoscopic group) and the method of open repairing surgery 143 cases (open group) at the same period were conducted. The differences in the operative time, rehabilitation activities time, length of stay, cost of hospitalization and 0comphcations, recurrence rate were compared. Results The laparoscopic group was significantly better in the operative time [ ( 14.8 ± 11.5) min ], found hiding oblique hernia ( 15 cases), rehabilitation activities time[ ( 16.5 ± 14.3) h], use of analgesics(5 cases), scrotal edema(1 case), length of stay[ (4.2 ± 1.5) d], than those of the open group [ ( 37.6 ± 25.4) min, 0, (52.7 ± 12.6) h, 13, 14, ( 8.4 ± 2.6 ) d respectively ] ; but the recurrence rate was no significantly different. Conclusion Method of fishing net repairing transverse fascia for inguinal hernia (type Ⅰ , Ⅱ ) using laparoscopie surgical procedure is feasible.
ABSTRACT
Objective To study the efficiency of iaparoscopic inguinal hernia repair without the use of a mesh. Methods We used laparoscopic hernia repair without the use of a mesh in 92 cases of inguinal hernia. Results were compared with that of total extraperitoneal laparoscopic inguinal hernioplasty(TEP) in 91 cases from January 2001 to March 2004. Results The laparoscopic procedures were successfully performed in all the patients. In mesh-free and TEP group respectively the operating time was (21±4) min vs. (70±16) min (t=28. 01, P<0.05), hospital stay was (3.5±1.0) d vs. (4.8±1.2) d (t=7.96, P<0.05), average time off-bed was (1.0±0.5) d vs. (1.8±0.7) d (t=8.90, P<0.05), duration of pain was (1.0±0.5) d vs. (2.5±0.7) d (t=16.69, P<0.05), the expense was (4500±500) RMB yuan vs. (8000±820) RM B yuan(t=34.89, P<0.05), subcutaneous hematoma rate was 0% vs. 8.7% (χ~2=6.48, P<0.05). The 48 hour C-reaction protein level after the operation was (3.9±0.3) mg/dl and (8.8±0.5) mg/dl (t=80.48, P<0.05). All the difference was statistically significant between the two groups. All patients were followed up for 56.9±6.2 months. The recurrence rate was 0 and 2.1% (χ~2=0.51,P>0.05) respectively. Conclusions Mesh-free laparoseopie inguinal hernia repair is safe, cost-effective, as well as of much lower hernia recurrence.
ABSTRACT
Objective To evaluate the feasibility and short-term outcome of laparoscopic operation for colorectal neoplasm in comparison with open operation procedure for colorectal neoplasm, laparoscopic operation for colorectal neoplasm may be critical in the evolving practice of medieine. Methods 234 cases of colorectal neoplasm were divided into two groups and was analyzed. 103 patients with colorectal neoplasm underwent laparoscopic operation (LCS), while 131 cases received open operation (OCS). Results The mean operating time in laparoscopic operation group was significantly longer than in open operation group (P <0.05). The blood loss was less. Time to pass flatus, time to ambulate and return of bowel function were restored earlier in laparoscopic operation group than that in open operation group (P <0.05). Duration of hospital stay were longer in open operation group than that in laparoscopic operation group (P <0.05). There was not significant difference in the length, distal margin, size of tumors and number of removed lymphatic nodes(P > 0.05) between the two groups. Laparoscopic colorectal resection is better in pathologic sample compared with the traditional open operation procedure. Conclusion Laparoscopic colorectal resection is secure and effective for colorectal neoplasm, and it is with lower blood loss during operation,earlier return of bowel function and shorter hospitalization, and provide better short-term outcome compared with the traditional open procedure.
ABSTRACT
Objective To evaluate the clinical efficacy and safety of retroperitoneal laparoscopic pyelolithotomy in the treatment of intrarenal pelvic staghorn calculus or multiple renal calculi. Methods Fifteen patients(9 males and 6 females)with average age of 40 years old were treated. The diameters of the calculi were from 1.5 cm to 3.7 cm. Three trocars were used in this procedure as rou-tine. The renal sinus was exposed by separating the pelvis from outside to inside until reaching the in-fundibulum of the renal calyx. Then the renal calyx was cut open and the calculus was taken out. Double J stent was placed in the ureter and the incision of pelvis was closed by 3-0 absorbable suture. The drainage tube was pulled out 3-4 d post-operatively according to the drainage quantity. Double J stent was then pulled out 2 weeks after surgery. Results All the 15 procedures were successfully completed. The average operation time was 170 min and the average post-operative hospital stay was 7 d. During the 3-15 months' follow-up, 2 patients had calculus remnants with the size of 0. 2-0.5cm in diameter. Conclusions Retroperitoneal laparoscopic pyelolithotomy provides a minimally inva-sive treatment option in patients with intrarenal pelvic staghorn calculus or multiple renal calculi. It has the advantages of good exposure, little bleeding, small incision and fast recovery.
ABSTRACT
Objective To evaluate the efficacy and application value of retroperitoneal laparoscopic nephroureterectomy for localized and poor differentiated renal pelvic carcinoma by comparing with open nephroureterectomy.Methods Thirty-three pelvic carcinoma patients underwent radical nephroureterectomy were retrospeetively analyzed.All tumors were confirmed to be localized,stage T1-T3 and grade 3.Retroperitoneal laparoscopic nephroureterectomy was performed in 12 patients,the ureteral orifice was resected in traditional way through a small incision in lower abdomen.Open radical nephroureterectomy was performed in 21 cases.Clinical outcomes of the patients were compared between the 2 surgery groups.Results Mean operative time was 232 vs 212 min(P=0.100)and blood loss volume was 162 vs 233 ml(P=0.001)in the laparoscopic and open nephroureterectomy groups.Mean postoperative hospitalization was 7.6 vs 9.8 d(P＜0.001)for the laparoscopic and open groups.During the followup for 7-67 months,all the 33 patients survived.There was no recurrence or metastasis in laparoscopic group.While there was 1 retroperitoneal recurrence,and 3 cases suffering from superficial bladder cancer in open surgery group.Conclnsion Retroperitoneal laparoscopic nephroureterectomy may be performed safely in local renal pelvic carcinoma patients with poor differentiated tumors,with less intraoperative blood loss and early recovery.
