Objective To analyze postoperative effect of a new rectopexy technique with Douglas pouch elevation for complete rectal prolapse (CRP) in adults.Methods From January 2010 to May 2011, 52 CRP cases were treated by rectopexy with Douglas pouch elevation.In terms of different surgical techniques, patients were divided into two groups : Group A (n =28) received laparoscopic rectopexy with Douglas pouch elevation;and Group B (n =24) received laparoscopic rectopexy with Douglas pouch elevation combined with procedure for prolapse and hemorrhoids (PPH).Rectal prolapse, constipation, and fecal incontinence in the two groups were assessed respectively before surgery, and on the 6th, 12th, and 24th month after surgery, postoperative complications were evaluated with severe grading of surgical complications.Results Symptoms of rectal prolapse disappeared at half a year after surgery in all patients, and relapsed to different extent afterwards.However, two years after operation, the status of rectal prolapse in Group B tended to be stable.The trend of constipation after surgery was consistent with that of rectal prolapse.In addition, fecal continence improved gradually on half a year after surgery in the two groups and recovered to the optimal status in the first postoperative year.However, in the second year, the results of fecal incontinence reduced slightly in Groups A, and Group B became stable.Two years after surgery, four cases in Groups A relapsed while there was no recurrence in Group B.Difference of Grade I to Grade Ⅲ complications among the two groups was statistically insignificant (x2 =0.05, P > 0.05).Conclusions The clinical effect of laparoscopic rectopexy with Douglas pouch elevation associated with the procedure for prolapse and hemorrhoids (PPH) is better than that without PPH for female and male CRP patients with severe symptoms.

Objective: To assess the potential significance of proliferating cell nuclear antigen (PCNA) labelling indexes (PCNA-LI) and AgNORs number in evaluation of proliferative activity of Wilms′ tumor. Methods: A silver staining for AgNORs and an immunohistochemical method PCNA staining were performed on the biopsy specimens taken from 34 children with Wilms′ tumor. Results: No significant differences were observed between PCNA-LI and the pathological types and clinical stages, whereas fraction of S-phase and PI and the number of AgNORs were significantly higher in patients with PCNA-LI≥25% than that in patients with PCNA-LI<25%. The number of AgNORs/cell correlated well with both pathological types and clinical stages. The combination of PCNA-LI and AgNORs can accurately reflect the proliferative activity of cancer cells in Wilms′ tumor. Conclusion: The current pathological types and clinical stages may reflect the aggressive activity in Wilms′ tumor, but insufficient. The simultaneous determination of PCNA-LI and AgNORs count could be used as the essential complementarity of conventional pathological types and stages for accurate evaluation of biologic behaviour of Wilms′ tumor.

In the process of hepatocarcinogenesis induced by diethylnitrosamine (DENA) in rats, the hepatocellular ultrastructure and G-6-Pase reactions in hepatic nodes were observed by electron microscope. The results are as follows: As compared with normal hepatocytes, cell junctions were fewer, even disappeared in some areas and intercellular spaces were wider; in some cells, nuclear membranes invaginated into the nucleoplasms frequently, micleoli were enlarged, mitochondria appeared swollen and their cristae were scanty- and short, and depolymerized ribosomes dropped off the dilated rough endoplasmic reticulums; in some seriously diseased cells, nucleoli were enlarged, abundant free ribosomes were present, but the' other organelles were in lower differencial state. G-6-Pase reactions were positive before the 8th week of DENA induction and negative after the 12th week. These suggest the hepatocellular metabolic disturbance and low differenciation.

Objective:
To investigate the clinical efficacy of laparoscopic subtotal colonic bypass plus colostomy with antiperistaltic cecoproctostomy (SCBCAC) in the treatment of senile slow transit constipation.
Methods:
A retrospective cohort study was performed. Clinical data of 30 colonic slow transit constipation patients aged ≥70 years old undergoing laparoscopic SCBCAC from July 2012 to October 2016 (bypass plus colostomy group), and 28 patients undergoing laparoscopic subtotal colonic bypass with antiperistaltic cecoproctostomy (SCBAC) from February 2009 to June 2012 (bypass group) at our institute were collected. Efficacy was compared between the two procedures. Inclusion criteria: (1) meeting the Rome III diagnosis criteria for constipation; (2) confirmed diagnosis of slow transit constipation; (3) age ≥ 70 years old; (4) receiving non-surgical treatment for more than 5 years, and Wexner constipation score > 15; (5) follow-up for more than 2 years. Those with psychiatric symptoms or previous psychiatric history, obvious signs of outlet obstructive constipation, organic diseases of the colon and life-threatening cardiovascular diseases or cancer were excluded. In the bypass plus colostomy group, laparoscopy was performed via five trocars. The ileocecal junction and the ascending colon were mobilized and the ileocecal junction was pulled down to the pelvic inlet. The ascending colon was transected and the appendix was excised. The lateral peritoneum of the sigmoid colon and the rectal mesentery were dissected and the upper rectum was transected. The avil of a circular stapler was placed in the bottom of the cecum. The shaft of the stapler was placed in the rectum via the anal canal to complete end-to-side anastomosis (end rectum to lateral cecum). The end of the rectal-sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0-20, the lower the better), the Wexner constipation scale (WCS, 0-30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0-144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0-10, the lower score, the better), and the abdominal bloating score (ABS, 0-4, the lower score, the better). The complications defined as Clavien-Dindo class II or above were observed and recorded.
Results:
No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all

OBJECTIVETo investigate the influence of length of preserved ileocecum on the efficacy of laparoscopic subtotal colectomy antiperistaltic cecorectal anastomosis (LSCACRA) in treating slow transit constipation (STC).
METHODSClinical data of 81 STC patients who received LSCACRA between April 2007 And December 2011 in the 150th Center Hospital of PLA were continuously collected. Patients were divided into two groups: 10 cm to 15 cm ascending colon preserved above ileocecal junction(10-15 cm group, n=41), and 2 cm to 3 cm ascending colon preserved above ileocecal junction (2-3 cm group, n=40). The Wexner constipation scale (WCS), Wexner incontinence scale(WIS), gastrointestinal quality of life index(GIQLI), abdominal pain intensity scale(NRS), abdominal pain frequency scale and abdominal bloating frequency scale in the two groups were determined and compared before and 6, 12, 24 months after operation.
RESULTSNo postoperative incontinence was found in all the patients. There were no significant differences in evacuation frequency between two groups at 6th and 12th month after surgery (all P>0.05). Two years after operation, barium enema emptying time examination revealed 2-3 cm group was (17.7±9.5) h, which was remarkably shorter than (21.2±20.7) h in 10-15 cm group (P=0.011). The WCS, GIQLI, NRS and abdominal pain frequency scale of two groups were improved obviously at 6th, 12th and 24th month after surgery (all P<0.01). Above parameters in 2-3 cm group were superior to 10-15 cm group (all P<0.01), but abdominal bloating frequency scale was not significantly different between the two groups (P>0.05). As compared with before operation, NRS in 2-3 cm group 6, 12, 24 months after operation reduced remarkably (all P<0.01), but did not improve obviously in 10-15 cm group (P>0.05).
CONCLUSIONThe shorter length of ascending colon preserved above ileocecal junction can improve the efficacy of LSCACRA in the treatment of STC and the prognosis of patients. Two to three cm length of ascending colon preserved above the ileocecal junction should be recommended.

The end of the rectal?sigmoid colon was used for colostomy via an extraperitoneal approach to complete the operation. The following efficacy indexes were collected before surgery and 3, 6, 12, and 24 months after surgery: the number of daily bowel movements, the Wexner incontinence scale (WIS, 0?20, the lower the better), the Wexner constipation scale (WCS, 0?30, the lower the better), the gastrointestinal quality of life index (GIQLI, 0?144, the higher score, the better), abdominal pain intensity indicated by the numerical rating scale (NRS, 0?10, the lower score, the better), and the abdominal bloating score (ABS, 0?4, the lower score, the better). The complications defined as Clavien?Dindo class II or above were observed and recorded. Results No significant differences in preoperative WCS, WIS, GIQLI, NRS, and ABS were observed between bypass plus colostomy group and bypass group (all P>0.05). All the patients successfully underwent laparoscopic surgery and no patient in either group experienced postoperative fecal incontinence. WCS and GIQLI were significantly improved (all P<0.001) at 3, 6, 12, and 24 months after surgery in both groups. At 12 months after surgery, the number of bowel movements was significantly less in bypass plus colostomy group than that in bypass group [(2.4±0.7) times vs. (3.4±1.2) times, t=4.048, P<0.001]. At 3, 6, 12 and 24 months after surgery, the improvement of GIQLI in bypass plus colostomy group was significantly better than that in bypass group (all P<0.001). At 24 months after surgery, GIQLI in bypass plus colostomy group and bypass group was 122.3 ± 5.3 and 92.8 ± 16.6, respectively, with a significant difference (t=9.276, P<0.001). At 12 and 24 months after surgery, NRS in bypass plus colostomy group was significantly better than that in bypass group (both P<0.001). At 24 months after surgery, NRS in bypass plus colostomy group was 0.9±0.7, while that in bypass group was 3.7±2.7. There was a significant difference between two groups (t=5.585, P<0.001). At 6, 12 and 24 months after surgery, the improvement of ABS in bypass plus colostomy group was also significantly better than that in bypass group. At 24 months after surgery, ABS in bypass plus colostomy group was 0.6±0.6, while that in bypass group was 2.5±1.0, with a significant difference between two groups (t=8.797, P<0.001). At 1 year after surgery, barium enema examination was performed in all the patients of both groups. The barium emptying time was (21.2 ± 3.8) hours and (95.8 ± 86.2) hours in bypass plus colostomy group and bypass group respectively. The former group was significantly better than the latter group (t=4.740, P<0.001). Conclusions Laparoscopic SCBCAC is an effective and safe procedure for the treatment of senile slow transit constipation and can significantly improve prognosis. Its clinical efficacy is better than laparoscopic SCBAC.
