We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

Robotic-assisted transanal total mesorectal excision (R-TaTME) has unique advantage in low rectal cancer. Single incision plus oneport (SIPOP) laparoscopic operation can synchronously cooperate with robotic-assisted transanal operation, in order to the difficulty of operation, improve the quality of operation and shorten the time of operation. A retrospective analysis was conducted on the clinical and pathological data of one patient who underwent SIPOP synchronously combined with R-TaTME + sigmoid-anal anastomosis + ileostomy at the Department of General Surgery, Army Characteristic Medical Center on September 11, 2019. This 71-year-old patient was male with body mass index of 24.08 kg/m(2) and received preoperative chemotherapy. Rectal adenocarcinoma was confirmed by colonoscopy biopsy, and distance from tumor lower edge to anal verge was 3 cm. MRI indicated T2N1 stage. The operation was completed successfully, and the transabdominal and robotic transanal surgery totaled 117 minutes, with 15 minutes for the robotic transanal preparation step. There was about 20 ml of intraoperative blood loss and no blood transfusion was performed. The patient was discharged 6 days after operation. No intraoperative or postoperative complications occurred. The postoperative TNM staging was stage I (pyT2N0cM0). No recurrence or metastasis was found at postoperative 7 month. It is a safe, effective and feasible technique for patients with low rectal cancer.

Objective: To evaluate the quality of life after Altemeier and Delorme procedures for rectal prolapse patients. Methods: A retrospective cohort study was performed. Clinical data of patients with full-thickness rectal prolapse undergoing surgical treatment in the Sixth Affiliated Hospital, Sun Yat-sen University from February 2013 to January 2018 were retrospectively analyzed. Patients who had no preoperative imaging data, who suffered from internal rectal intussusception, or who did not undergo Altemeier and Delorme operations were excluded. Sixty-seven patients were enrolled, including 32 males with median age of 20.5 (13, 34) years and 35 females with median age of 65.0 (50, 77) years. According to different procedures, patients were divided into the Altemeier group (48 cases) and the Delorme group (19 cases), who received standard Altemeier and Delorme operations respectively. The maximal prolapse length of preoperative squat position, the Longo constipation score, Wexner incontinence score, EQ-5D-5L score, postoperative complications and recurrence rate were analyzed and compared between two groups. Results: The maximal prolapse length of preoperative squat position in Altemeier group and Delorme group was (7.3±3.3) cm and (4.9±2.1) cm respectively with significant difference ( t =2.907, P =0.005). The operations in both groups were successfully completed. The operation time and postoperative hospital stay of Altemeier group were longer than those of Delorme group [(112.3±47.0) minutes vs. (80.7±35.4) minutes, t =2.637, P =0.010; (11.3±5.0) days vs. (8.6±3.0) days, t =2.177, P =0.033]. The median follow-up period was 26 (13, 45) months. In the last follow-up, compared to pre-operation, the Longo constipation score [9.0 (6.0, 14.0) vs 4.0 (1.0, 6.5), Z =-4.989, P <0.001], Wexner incontinence score [0 (0, 5.5) vs. 0 (0, 2.0), Z =-3.325, P <0.001] and EQ-5D-5L score [45.0 (40.0, 57.5) vs. 80.0 (70.0, 87.5), Z =-5.587, P <0.001] were all improved obviously in the Altemeier group, meanwhile Longo constipation score [6.0 (5.0, 14.0) vs. 3.0 (1.0, 7.0), Z =-2.186, P =0.029], Wexner incontinence score [0 (0, 12.0) vs. 0 (0, 4.0), Z =-2.325, P =0.020] and EQ-5D-5L score [50.0 (35.0, 60.0) vs. 75.0 (65.0, 90.0), Z =-3.360, P =0.001] in the Delorme group were all improved obviously as well. The postoperative morbidity of complication between the two groups was not significantly different [10/48 (20.8%) vs. 4/19 (21.1%), χ(2)=0.049, P =0.826]. Sixteen patients (28.0%) relapsed after operation, including 10 patients in the Altemeier group and 6 patients in the Delorme group, without statistically significant difference ( P =0.134). Conclusions: Both the Altemeier and Delorme procedures are effective treatments for rectal prolapse, which can improve the postoperative quality of life. Delorme procedure has the advantages of shorter operation time and faster postoperative recovery in patients with mild prolapse.

Objective: To investigate the safety, feasibility and long-term outcomes of laparoscopic complete mesocolic excision for the transverse colon cancer., Methods: Clinical data of 61 patients who underwent laparoscopic complete mesocolic excision for transverse colon cancer (transverse group) in our department from January 2011 to January 2014 were retrospectively analyzed, which were compared with those of 155 patients undergoing laparoscopic complete mesocolic excision for ascending colon cancer (ascending group) and 230 patients undergoing laparoscopic complete mesocolic excision for sigmoid colon cancer (sigmoid group). Differences in operative details, postoperative recovery, postoperative complications and long-term survival among 3 groups were evaluated., Results: No significant differences in the baseline information were found among 3 groups(all P>0.05). The average operative time was significantly longer in transverse group as compared to ascending group and sigmoid group [(192.1±58.7) min vs. (172.2±54.7) min and (169.1±53.6) min]( P<0.05), while the blood loss [(89.7±63.6) ml, (86.3±66.3) ml, (82.6±61.5) ml], conversion rate [3.3%(2/61), 2.6%(4/155), 2.2%(5/230)], number of harvested lymph node (13.0±4.7, 14.4±6.5, 13.4±5.6), time to flatus [(2.7±1.1) d, (2.6±1.1) d, (2.5±1.0) d], time to liquid diet [(3.0±1.7) d, (2.8±1.5) d, (2.7±1.4) d], incidence of postoperative complication(6.6%, 9.0%, 11.7%), and hospital stay [(11.6±5.8) d, (10.7±5.8) d, (10.6±5.7) d] among 3 groups were not significantly different (all P>0.05). A total of 436 patients received postoperative follow-up of median 36 (5 to 67) months. The overall 5-year survival rate was 73.1%, 73.7% and 74.8%, and the 5-year disease-free survival rate was 71.5%, 71.1% and 72.7% in transverse, ascending and sigmoid colon cancer groups respectively, whose differences were not significant among 3 groups (all P>0.05)., Conclusion: Laparoscopic complete mesocolic excision for transverse colon cancer is safe and feasible with slightly longer operation time, and has quite good long-term oncologic efficacy.

Objective: To investigate the risk factors of postoperative urinary retention after rectal cancer surgery., Methods: Clinical data of 133 patients with rectal cancer undergoing radical surgery from January 2013 to September 2014 in the General Hospital of the PLA Rocket Force were retrospectively analyzed. Time to the first removal of urinary catheter, incidence of postoperative urinary retention, and time to re-insert indwelling catheter were recorded. Risk factors of urinary retention were analyzed., Results: Of 133 patients, 70 were males and 63 were females, with a median age of 62 (20-79) years old. Distance from tumor lower margin to anal verge were ≤5 cm in 58 patients, >5 cm to 10 cm in 41 patients, and >10 cm to 15 cm in 34 patients. The postoperative TNM stage was recorded in 35 patients with stage I(, 34 with stage II(, 59 with stage III( and 5 with stage IIII(. Surgical procedures included anterior resection (AR) for 92 patients, abdominoperineal resection (APR) for 25 patients and intersphincteric resection (ISR) for 16 patients. Laparoscopic approach was performed in 89 patients compared with open operation in 44 patients. Time to the first removal of urinary catheter was 2-7 days after operation (median, 5 days) and 36 (27.1%) patients developed urinary retention. All the 36 patients achieved spontaneous voiding by re-inserting urinary catheter for 2-28 days (median, 6 days). Univariate analysis showed that elderly (>65 years) and laparoscopic approach had significantly higher incidence of urinary retention [37.5%(21/56) vs. 19.5%(15/77), χ 2 =5.333, P=0.021; 34.8%(31/89) vs. 11.4%(5/44), χ 2 =8.214, P=0.004; respectively]. Multivariate logistic analysis demonstrated that old age(OR=3.949, 95%CI:1.622 to 9.612, P=0.002), laparoscopic approach (OR=5.665, 95%CI:1.908 to 16.822, P=0.002), and abdominoperineal resection (OR=3.443, 95%CI:1.199 to 9.887, P=0.022) were independent risk factors of urinary retention after rectal cancer surgery., Conclusions: Patients undergoing rectal cancer surgery have a high risk of postoperative urinary retention. More attention should be paid to the old patients, especially those undergoing laparoscopic procedure or abdominoperineal resection, to prevent postoperative urinary retention and urinary dysfunction.

Objective: To investigate the safety and feasibility of laparoscopic extraperitoneal sigmoid colostomy., Methods: Thirty-six patients with low rectal cancer undergoing laproscopic abdominoperineal resection from July 2011 to July 2012 were prospectively enrolled in the study and randomly divided into extraperitoneal colostomy group(EPC, n=18) and internal peritoneal colostomy group(IPC, n=18). Follow-up period was 4-16 (median, 7) months and postoperative complications were compared between two groups., Results: One case in EPC group was converted to IPC because of poor blood supply of the proximal sigmoid, who was eliminated from the subsequent analysis. Compared with the IPC group, the surgery time was longer in EPC group [(25.3±8.5) min vs. (14.7±6.4) min], while the difference was not statistically significant(P>0.05). Each group had 1 case of stoma ischemia, who both received the colostomy reconstructive surgery. The incidence of stoma edema was significantly higher in EPC group[35.3%(6/17) vs. 0, P<0.05). The early postoperative complications rate did not significantly different between the two groups[58.8%(10/17) vs. 27.8%(5/18), P>0.05]. The late postoperative complications rate was 22.2%(4/18) in IPC group, including 1 case of stoma prolapse, 1 case of stoma stenosis and 2 cases of parastomal hernia. No later postoperative complication occurred in EPC group., Conclusion: Extraperitoneal sigmoid colostomy is an easy and safe procedure with lower late complications as compared to internal peritoneal sigmoid colostomy.

Objective: To investigate the emergency therapeutic strategy for sigmoid vovulus in the elderly., Methods: Clinical data of 14 elderly patients with sigmoid vovulus were analyzed retrospectively., Results: The mean age was(79.1±7.2) years(range, 70-93), and 11 patients (78.6%) were male. Emergency decompression and restoration with colonoscopy was performed in all the patients with a success rate of 100%. No patient required emergent surgery. Four patients(28.6%) recurred and they were managed well by repeat colonoscopic restoration., Conclusion: Emergency colonoscopic restoration is the first treatment of choice for sigmoid vovulus in the elderly because it is safe and effective, and can be performed repeatedly.

Objective: To explore the changes of bowel function in spinal cord injury (SCI) patients undergoing sigmoid augmentation cystoplasty., Methods: From September 2005 to January 2011, 30 SCI patients undergoing sigmoid augmentation cystoplasty were surveyed by follow-up questionnaires at Beijing Charity hospital and Affiliated Hospital of Nantong University., Results: Among them, 18 cases (60.0%) believed their defecation became softer and 18 cases (60.0%) thought their defecation time became shorter. The postoperative profiles of patient defecation traits and defecation time were better (P < 0.05), especially traumatic SCI patients (P < 0.05)., Conclusion: The subtotal resection of sigmoid colon improves the defecation of spinal cord injury patients. The SCI patients undergoing sigmoid augmentation cystoplasty may avoid urinary tract dysfunctions and improve bowel dysfunction.

To evaluate the protection of proximal colon segment by analyzing blood supply disorder of proximal colon segment during laparoscopic proctosigmoidectomy(11 cases) in the Chaoyang Hospital of Capital Medical University. It is concluded that the disorder of blood supply of proximal colon segment during laparoscopic proctosigmoid surgery has two reasons. One is the anatomic factor of mesenteric vessels; the other is the inappropriate operative procedure. It is recommended that left colonic artery should be retained, and inferior mesenteric artery should be handled at a low level, thus, the risk of proximal intestine blood supply disorder caused by vascular anatomy variation can be reduced.

Objective: To explore the effects of splenic flexure and sigmoid colon variation on anastomosis after left colectomy., Methods: The clinical data of 76 descending colon patients were collected retrospectively from March 2004 to April 2011 at our hospital. Statistical analysis was performed for the types of splenic flexure and sigmoid colon with regards to the choice of anastomosis., Results: There were mesenteric type (n = 55), mobile type (n = 7) and adhesive type (n = 14) for splenic flexure. And among 61 regular types, 15 were of variable type for sigmoid colon variation. There was significant difference of anastomosis between the types of sigmoid colon variation [43 (78.2%) vs 5 (71.4%) vs 9 (64.3%), P > 0.05] while no significant difference existed between the types of splenic flexure [I type 56(91.8%) vs II type 1 (14.3%), III or IV type 0, P < 0.05]., Conclusion: A clinician should pay more attention to the types of sigmoid colon variation. And it helps to select the right approach of anastomosis after left colectomy.

Objective: To report the first case and detailed techniques of laparoendoscopic single-site surgery (LESS) radical cystectomy with orthotopic taenia myectomy sigmoid neobladder for organ-confined bladder cancer., Methods: A 74-year-old man presented with gross hematuria for 2 months and biopsy revealed bladder cancer. LESS radical cystectomy and bilateral pelvic lymphadenectomies were performed using a single multilumen port inserted through a solitary 3.5 cm lower abdominal incision with conventional laparoscopic instruments. The taenia myectomy sigmoid pouch was then constructed by open procedure., Results: The total operative time was 9.5 h, and the LESS procedure lasted for about 5.5 h. No other port incision was added. The final pathology revealed urothelial carcinoma. The estimated intraoperative blood loss was 600 ml with blood transfusion of 400 ml. The pelvic lymph nodes and the surgical margins of the ureters and urethra were all free of tumor invasion. No water electrolyte and metabolic acid-base balance disorders were observed perioperatively. The neobladder capacity was about 280 ml, with a residual urine volume of 10 ml and peak flow rate of 11.1 ml/s 3 months postoperatively., Conclusion: Although with a steep learning curve, LESS surgery can be a less invasive and promising alternative to muscle-invasive bladder carcinoma.

Objective: To assess the penile erectile function, urinary continence and voiding, and cancer recurrence in 18 bladder cancer patients after sexuality preserving cystectomy and Roux-y sigmoid neobladder reconstruction., Methods: Eighteen male patients with bladder cancer underwent sexuality preserving cystectomy and Roux-y sigmoid neobladder reconstruction, and were followed up for cancer recurrence and such clinical outcomes as erectile function and urinary continence and voiding., Results: The patients were followed up for an average of 41 months, of whom, all achieved day- and night-time urinary continence, but 2 with positive lymph nodes died of extensive metastasis at 10 and 15 months, respectively, after surgery. Among the total number, potency was maintained in 11 patients (61.1%), impaired in 2 and lost in 5, and the post-operative IIEF-5 score was (10.83 +/- 8.25) as compared with (13.72 +/- 6.39) before the operation, with a statistically significant difference (P < 0.05)., Conclusion: Erectile function and urinary continence are fairly good in bladder cancer patients after sexuality preserving cystectomy and Roux-y sigmoid neobladder reconstruction, and the oncological results are fairly acceptable, but still need to be confirmed by longer follow-ups and larger trials.

Objective: To investigate the effect of GORE-TEX Dual Mesh fixing into peritoneum in sigmoid-colostomy on the prevention of peristomal hernia., Methods: Sixty patients undergone sigmoid-colostomy from Jan. 2003 to Jan. 2005 in the first affiliated hospital of Sun Yat-sen University were selected and randomly divided into two groups. Patients received papillary sigmoid-colostomy through rectus abdominis and peritoneum in control group and GORE-TEX Dual Mesh fixing into peritoneum during sigmoid-colostomy in observation group. Complications and recurrence rate were recorded in follow-up period., Results: Peristomal hernia occurred in eight patients (8/30) in control group (26.7%), while no hernia happened in observation group (0/30)., Conclusion: GORE-TEX Dual Mesh fixing into peritoneum in sigmoid-colostomy can prevent peristomal hernia.

Objective: To present a case of laparoscopic radical cystectomy and detenial sigmoid colon orthotopic neobladder reconstruction for bladder tumor in a child., Methods: A 3-year-old boy with bladder rhabdomyosarcoma underwent laparoscopic radical cystectomy and detenial sigmoid colon orthotopic neobladder reconstruction. The bilateral pelvic lymphadenectomy and cystectomy were performed laparoscopically, and removal of the mobilized specimens and urinary diversion operation were managed through enlarged abdomen incision. The urinary diversion procedure included construction of the detenial sigmoid pouch, bilateral stented antiflux implantation of the ureters in the pouch and orthotopic anastomosis of the neobladder with the urethra., Results: The total operative time was 6 h, and the laparoscopic procedure lasted for about 3.5 h. The intraoperative blood loss was 50 ml, and 200 ml concentrated red blood cell transfusion was used for the safety of the patient. Six dissected lymph nodes in each pelvic side and the surgical margins of the ureter and urethra were all free of tumor invasion. Bowel peristalsis recovered 3 days after the operation, and the pelvic drainage and the neobladder drainage tubes were removed on day 7 and 14, respectively. The urethral catheter and ureteral stents were removed 25 days after the operation. The daytime urine control and micturition recovered 1 week after the operation. The neobladder capacity was about 110 ml, with residual urine volume of 10 ml and peak flow rate of 12 ml/s after 5 months. No perioperative complications occurred such as water-electrolyte and metabolic acid-base balance disorders, urinary leakage, reflux or bowel obstruction., Conclusion: Laparoscopic radical cystectomy is minimally invasive, reduces intraoperative blood loss and allows rapid postoperative recovery, and can be a promising approach to management of bladder rhabdomyosarcoma in children.

Objective: To assess the therapeutic effects of low tension, anti-reflux Roux-y sigmoid neobladder., Methods: A total of 21 patients (7 male and 14 female) were included, aged 43-87 years. All cases received radical cystectomy and low tension Roux-y sigmoid neobladder procedure for invasive bladder cancer were included in this study. The period of follow-up was from 8 to 79 months (the average was 36 months). Evaluations included urinary flow rate, post voiding residual and filling cystometry., Results: The mean maximum urinary flow rate, the voiding time and the post voiding residual were 28.1 ml/s (21.4-38.4 ml/s), 17 s(9-28 s) and 0 ml respectively. The cystometric capacity was 480 m1 (350-560 ml). The volume of desire to void was 330 ml (120-410 ml). The bladder pressure was from 14.2 to 18.6 cm H2O (the average bladder pressure was 16.4 cm H2O) at high filling volumes. The maximum voiding pressure was 45.0 cm H2O (23.6-63.4 cm H2O)., Conclusions: The Roux-y sigmoid neobladder has an adequate capacity at low pressure with a satisfactory continence, and it is an effective method for continent urinary diversion.

Objective: To assess the clinical value of sigmoid coloplasty of super-lower anastomosis., Methods: Thirty-five patients underwent sigmoid coloplasty (treatment group), while 33 patients received straight sigmoidorectostomy (control group). Complication rate and anal function were observed and compared between the two groups., Results: The complication rate was 17.1% and 21.2% in the study group and control group respectively (P> 0.05). Average stool frequency were 2 times (1-5.5 times) a day in the study group and 3.5 times (1-9 times) a day in the control group 12 months after operation (P< 0.01). The fecal continence and self-satisfaction were improved significantly in the study group than that of the control group(P< 0.01, respectively). The postoperative anal function score was 2.57 in the study group and 7.21 in the control group, there was significant difference between the two groups (P< 0.01)., Conclusions: Compared with straight sigmoidorectostomy, sigmoid coloplasty applied in super-lower anastomosis can significantly improve the recovery of anal function without increasing complication rates.

Objective: To review our experience with intracorporeal laparoscopic radical cystectomy and sigmoid colon orthotopic neobladder reconstruction., Methods: The clinical data of 26 cases of bladder carcinoma treated with the indicated surgical procedures were reviewed., Results: The surgeries were successful in all the cases with the operating time ranging from 240 to 390 min, blood loss of 400 to 800 ml and red-cell transfusion of 0-4 U. Oral food intake was allowed 4-8 days after the operation, ureteral stents were removed in weeks 3 to 8 and the pouch catheter was removed in week 4 postoperatively. Daytime urinary continence was excellent and urinary incontinence at night occurred in 8 patients 3 months after the operation., Conclusion: Sigmoid colon orthotopic neobladder reconstruction can be effective for urinary diversion to ensure good quality of life of the patients.

Background & Objective: Although total cystectomy plus neobladder is widely used, with good outcome, to treat men patients with invasive bladder cancer, the experience of treating women patients with the same therapy is limit. This study was designed to investigate the outcome of total cystectomy plus sigmoid neobladder for women patients with invasive bladder cancer., Methods: Clinical data of 8 women with invasive bladder cancer, who underwent total cystectomy plus sigmoid neobladder from Jan. 2002 to Oct. 2003 in Cancer Center of Sun Yat-sen University, were retrospectively analyzed., Results: The operations were technically successful in all cases. The mean follow-up was 18 months (ranged 6-24 months). Six patients survived disease-freely;2 developed pelvic metastasis 6 and 12 months after operation respectively. All patients could actively urinate, 4 were continent day and night, 4 were continent at daytime with mild nocturnal incontinence. Mild hydronephrosis was detected in 1 patient 3 months after operation, which disappeared spontaneously 3 months later. Renal function and serum electrolytes were normal in all cases., Conclusions: Total cystectomy plus sigmoid neobladder could manage invasive bladder cancer in women patients, and the new bladders function well. But night continence in women patients is not as good as that in men patients.

Objective: To investigate the clinical outcome of sigma rectum pouch as a continent form of urinary diversion., Methods: The clinical data of 38 patients, 32 males and 7 females, aged 53.2 (42 - 68) with muscle-invading bladder carcinoma who underwent a Mainz pouch II procedure after radical cystectomy 1996 - 2001 were analyzed. The intestine was incised over a length of 20 - 24 cm with the junction of sigmoid colon and rectum as the midpoint so as to create a low-pressure reservoir for urine and side-to-side anastomosis was performed on the posterior borders of the rectosigmoid wall. Submucosal tunnel technique was employed in antireflux urethral implantation. The patients were followed up for 7 - 60 months with a mean of 30 months postoperatively., Results: Continence has been achieved in all the 38 patients with a micturition frequency of 3 - 5 times during daytime and 0 - 3 times at night. The mean volume of pouch was 515.6 ml (400 - 650 ml). The basal intra-reservoir pressure was 8 - 23 cm H(2)O (mean 16.5 cm H(2)O, 1 cm H(2)O = 0.098 kPa), the highest peak pressure was 12 - 33 cm H(2)O (mean 21.3 cm H(2)O)., Conclusion: A modified sigmoid rectal pouch procedure provides a reservoir with a higher capacity and lower pressure without a reflux to the upper urinary tract and descending colon with lower incidence of complication, it is also a better alternative diversion procedure that would be easily accepted by surgeons and patients.

Objective: To explore the procedures and the clinical significance of laparoscopy and laparoscopically assisted sigmoid transplantation for vaginal construction., Methods: Nine cases were assigned randomly to laparoscopically assisted sigmoid colpopoiesis and laparoscopic sigmoid colon colpopoiesis. The procedure of laparoscopically assisted sigmoid colpopoiesis: with the auxiliary of laparoscopy, dissected the distal portion of the sigmoid with endoscopic linear cutter, then a 4-cm incision was made in the left lower abdomen to retract and dissect the proximal portion of sigmoid. After the proximal portion of transplant-sigmoid was closed, the proximal cut end of reserved-sigmoid was placed with the anvil and made a purse-string suture, then put back sigmoid into the peritoneal cavity. A curved intraluminal stapler was inserted from the anus to the most distal cut end of reserved-sigmoid to end-end anastomose the reserved-sigmoid. Finally, an artificial canal was made between urethravesicae and rectum and the transplant-sigmoid with the blood supply was placed into the artificial canal to create an artificial vagina. The procedure of laparoscopic sigmoid colpopoiesis was performed under laparoscopy thoroughly., Results: We have successfully completed the operations for 9 patients, and made 1 - 19 month following-up. The results of the artificial vaginae of all cases were satisfactory; the abdominal scar was small with remarkable cosmetic effects. Moreover, 5 cases had pleasant sexual intercourses., Conclusion: The procedures of laparoscopy and laparoscopically assisted sigmoid transplantation for vaginal construction can replace the traditional laparotomy.

Background & Objective: Quality of life (QOL) in the patients who are performed radical cystectomy is affected by the methods of urinary diversion. The patients with continent or non-continent urinary diversion could not void by themselves and their QOL was poor. However, the intestinal neobladder in situ could provide the patients with good voiding and improve QOL. Unfortunately, some degree of poor empty and incontinence would occur in these patients. The aim of this paper was to report the authors' experience of modified intestinal in situ neobladder in reconstructing the lower urinary tract after radical cystectomy., Methods: Reconstruction of the lower urinary tract using modified sigmoid neobladder (in 12 patients) and modified ileal neobladder (in 3 patients) was carried out in 15 patients (male 14, female 1; age 33-68 years, mean 53 years) who underwent radical cystectomy for invasive bladder cancer. The patients were followed up for 3-30 months. Nine of them were followed up for more than 16 months. Clinical outcome of these patients including the function of the neobladder, urinary function, sexual status, renal function, serum electrolytes, and QOL was evaluated., Results: All patients voided well by themselves and did not need self-catheterization. Thirteen patients were continent in daytime and night-time. One patient was continent in daytime, but had mild incontinence at night. A female patient had moderate stress incontinence. The capacity of the neobladder was 240-640 ml and the residual volume was 0-250 ml. Renal function was normal in all patients. Serum electrolytes were normal in 14 patients. Metabolic acidosis and unilateral ureteral dilation was encountered in one patient respectively. Nine male patients restored sexual function and 13 patients came back to work. All patients felt satisfied with the function of the neobladder., Conclusion: Satisfactory urinary continence and voiding function was achieved with modified intestinal neobladder, which was believed an ideal procedure for lower urinary tract reconstruction after radical cystectomy.
