Laparoscopic minimally invasive sacrocolpopexy or hysteropexy and transobturator tape combined with native tissue repair of the vaginal compartments in patients with advanced pelvic organ prolapse and incontinence.

INTRODUCTION AND HYPOTHESIS: The aim of the study was to evaluate hysterectomized and non-hysterectomized patients with prolapse and incontinence. Laparoscopic sacrohysteropexy (LSHP) and minimally invasive sacrocolpopexy (LMSCP) were done in combination with transobturator tape (TOT) and native tissue repair of the anterior and posterior vaginal compartments in patients with pelvic organ prolapse (POP) and occult, stress, or urinary incontinence (SUI). The hypothesis is that both methods are successful. METHODS: A total of 81 patients with POP were evaluated: 44 had vaginal vault prolapse (POPQ points Ba, C, and Bp were 1.2, 2.6, and 0.4, respectively) and 37 had uterine prolapse (POPQ points Ba, C, and Bp were 1.8, 1.7, and 1.3, respectively). LMSCP (which means less dissection of the vagina in its upper third and avoiding possible collision with the ureters anteriorly or the rectum posteriorly) was performed in patients with vault prolapse, whereas patients with uterine prolapse underwent LSHP. Transobturator tape (TOT) was placed in all patients to treat symptomatic and occult urinary incontinence. Systematic anterior and posterior colporrhaphy was performed in both groups. RESULTS: Both groups showed anatomic (p < 0.0001) and symptomatic improvement (p < 0.001-p < 0.05). Voiding was significantly improved after surgery without postoperative incontinence (p < 0.001). There was no significant difference between groups regarding duration of surgery (p = 0.06), hospital stay (p = 0.13), blood loss (0.83), Clavien-Dindo grade 3 (p = 0.87), and Clavien-Dindo grade 1-2 (p = 0.92) complications. CONCLUSION: Minimally invasive LSCP or LSHP combined with TOT and native tissue repair of the anterior and posterior vaginal compartment is a successful treatment for POP.

Does robot-assisted minimally invasive oesophagectomy have superiority over thoraco-laparoscopic minimally invasive oesophagectomy in lymph node dissection?

Although robotic techniques have been used for oesophagectomy for many years, whether robot-assisted minimally invasive oesophagectomy (RAMIE) can actually improve outcomes and surpass thoraco-laparoscopic minimally invasive oesophagectomy (MIE) in the success rate of lymph node dissection remains to be empirically demonstrated. Therefore, we performed this systematic review and meta-analysis of case-control studies to systematically compare the effect of lymph node dissection and the incidence of vocal cord palsy between RAMIE and MIE. The PubMed, EMBASE, and Web of Science databases were systematically searched up to December 1, 2019, for case-control studies that compared RAMIE with MIE. Thirteen articles were included, with a total of 1,749 patients with esophageal cancer, including 866 patients in the RAMIE group and 883 patients in the MIE group. RAMIE yielded significantly larger numbers of total dissected lymph nodes (WMD = 1.985; 95% CI, 0.448-3.523; P = 0.011) and abdominal lymph nodes (WMD = 1.686; 95% CI, 0.420-2.951; P = 0.009) as well as lymph nodes along RLN (WMD = 0.729; 95% CI, 0.348-1.109; P < 0.001) than MIE. Additionally, RAMIE could significantly decrease estimated blood loss (WMD = -11.208; 95% CI, -19.358 to -3.058; P = 0.007) and the incidence of vocal cord palsy (OR = 0.624; 95% CI, 0.411-0.947; P = 0.027) compared to MIE. Compared with MIE, RAMIE resulted in a higher total lymph node yield and a higher lymph node yield in the abdomen and along RLN, along with reduced blood loss during surgery and the incidence of vocal cord palsy. Therefore, RAMIE could be considered to be a standard treatment, with less blood loss, lower incidence of vocal cord palsy, and more radical lymph node dissection, exhibiting superiority over MIE.

Laparoscopic-assisted mini percutaneous nephrolithotomy for treatment of large calculi in pelvic ectopic kidney.

We report two cases of male patients with pelvic ectopic kidney with large stones cleared with laparoscopic-assisted minimally invasive percutaneous nephrolithotomy (Mini-PERC) and holmium laser. These are the first cases of Mini-PERC done for pelvic ectopic kidney reported thus far.

Effect of Laparoscopic Minimally Invasive on Anorectal Dynamics and Serum CEA and CA724 in Patients with Rectal Cancer / 现代生物医学进展

Objective:To explore the effect of laparoscopic minimally invasive on anorectal dynamics and serum carcino-embryonic antigen (CEA) and carbohydrate antigen 724 (CA724) in patients with rectal cancer.Methods:38 cases of rectal cancer patients were selected as the research group from March 2014 to March 2016 and 40 cases of non neoplastic intestinal polyps as control group,Preoperative anorectal dynamics index (anal resting pressure (ARP),rectal resting pressure (RRP)and anal maximal contraction pressure (MSP),rectal maximum tolerated volume (MTV) of two groups were compared,Preoperative and 3 d,1,2 weeks after operation of serum CEA and CA724 levels were detected in the research group and the clinical curative effect was observed.Results:There was no significant difference of ARP,RRP,MSP,MTV before operation in research group compared with the control group(P＞0.05),and was significantly reduced 2,4 weeks after operation(P＜0.05),then gradually restored,and basically recovered to the preoperative level 12 weeks after operation.There was no significant difference of serum CEA and CA724 levels 3 d after operation compared with preoperative in research group (P＞0.05),and were significantly lower 1,2 weeks after operation compared with preoperative (P＜0.05).The clinical effective rate was 65.8％.Conclusion:Efficacy of laparoscopic minimally invasive in treatment of rectal cancer is effective,can effectively reduce the levels of tumor markers,although there are some influence on anorectal dynamics,but it can be returned to normal in the short term.
