128 Background: Appropriate tissue tension and clear visibility of the dissection area using traction are essential for effective and safe colonic endoscopic submucosal dissection (ESD). In this preclinical ex vivo and in vivo animal study, we developed a concealable robotic-assisted traction device and evaluated its performance in colorectal ESD. Methods: An experienced endoscopist performed ESD on an ex vivo porcine colon 18 times using our robot and 18 times using the conventional method. The outcome measures were procedure time, dissection speed, procedure-related adverse events, and blind dissection rate. We also conducted an in vivo feasibility study in live pigs. Robotic ESD was performed by experienced and novice endoscopist groups (n = 2, each). The outcomes included time to complete each ESD step, total procedure time, size of the dissected mucosa, rate of en bloc resection, and major adverse events. Results: Thirty-six colonic lesions were resected from ex vivo porcine colon samples. The total procedure time was significantly shorter in robotic ESD (RESD) than in conventional ESD (CESD) (20.1±4.1 vs. 34.3±8.3; P < 0.05). The submucosal dissection speed was significantly higher in the RESD group than in the CESD group (36.8±9.2 vs. 18.1±4.7; P < 0.05). The blind dissection rate was also significantly lower in the robotic group (12.8±3.4% vs. 35.1±3.9%; P < 0.05). In an in vivo feasibility study, the robot was attached to the colonoscope and successfully inserted into the proximal colon without damaging the colonic wall, and ESD was successfully performed. There was no significant difference in the submucosal dissection speed between the groups (P = 0.465). Conclusions: When the concealable robot assisted the colonic ESD procedure, the dissection speed and safety profile improved significantly. Thus, our robotic device can provide a simple, effective, and safe multidirectional traction during colonic ESD. When the robot was assisting in the ESD procedure, the dissection speed improved significantly, especially in the novice endoscopists.

Defunctioning ileostomies provide faecal diversion in major colorectal surgery. This reduces the consequences of an anastomotic leak. However, the formation of an ileostomy carries risks including obstruction at the level of the fascia. Post-operative oedema at the level of the fascia may contribute to obstruction. We hypothesize that the prophylactic insertion of a Foley catheter into the afferent limb of a defunctioning loop ileostomy may help decompress and improve time to low-residue diet (LRD). The objective of the study was to assess the feasibility of a Foley catheter, prophylactically inserted into the afferent limb of a defunctioning loop ileostomy, after major colorectal surgery. The study was a prospective pilot-randomized controlled trial. Ethical approval was obtained from Northern B Health and Disability Ethics Committee 15/NTB/91 ANZCTR Trial ID: ACTRN12615000691549. Forty-nine patients undergoing major elective colorectal surgery with a defunctioning ileostomy, between the years of 2015 and 2018 at North Shore Hospital, Auckland, New Zealand were included in this study. Patients were randomly allocated to either the Foley catheter (n = 26) or non-Foley catheter (n = 23) group. The median time taken to tolerate LRD the primary outcome, was 2 days in the Foley group versus 2 days in the non-Foley group (P = 0.05). There were no differences in the secondary outcome measures such as time to stoma output, length of stay or complications. This trial failed to show a statistical difference in time taken to tolerate a LRD residue in the Foley catheter group. There was no difference in length of stay, time to flatus or stoma output.

318 Background: Effective traction and counter-traction for visualizing the dissection plane in endoscopic submucosal dissection (ESD) is difficult to be achieved with a conventional endoscope. We developed a robotic assistive traction device for flexible endoscopy that provides multi-directional traction during ESD. We compared its safety and efficiency in ESD between experienced and novice endoscopists. Methods: Robotic ESD was performed by experienced and novice endoscopist groups (n = 2, each). The outcomes included time to complete each ESD step, total procedure time, size of the dissected mucosa, rate of en bloc resection, and major adverse events. Furthermore, incision and dissection speeds were compared between groups. Results: Twenty gastric lesions were resected from nine live pigs. The submucosal incision speed was significantly faster in the expert group than in the novice group (P = 0.002). There was no significant difference in the submucosal dissection speed between the groups (P = 0.365). No complications were reported in either group. Conclusions: When the robot was assisting in the ESD procedure, the dissection speed improved significantly, especially in the novice surgeons. Our robotic device can provide simple, effective, and safe multidirectional traction during ESD.

Objective: The purpose of this study was to compare the efficacy of extra-amniotic Foley catheter with intra cervical Dinoprostone gel for preinduction cervical ripening. Study Design: A randomized, prospective study was conducted in the Department of Obstetrics and Gynecology, PGIMS Rohtak on 100 pregnant women admitted for induction of labor. Fifty patients were randomized to receive Dinoprostone gel and 50 patients to receive intracervical, extra-amniotic Foley catheter. Results: The two groups were comparable with respect to maternal age, parity, gestational age, indication for induction, and initial Bishop scores. Both groups had a significant change in Bishop score (4.18 ± 1.81 and 4.6 ± 1.48 respectively, p < 0.001); however, there was no significant difference between the groups. Mean duration of induction to delivery was 18.51 ± 8.52 in Foley catheter group and 18.21 ± 11.13 in prostaglandin group, the difference being statistically insignificant. Among 50 cases of prostaglandin only single dose was sufficient for 23 (46%) cases to induce labor. But in 27 (54%) cases 2nd dose of prostaglandin were required. The expenditure of intervention showed that Rs. 325 were required for induction by prostaglandin as compared to Rs. 60/- for Induction by Foley’s catheter and the difference was highly significant statistically There was no difference between the groups in mode of delivery, infant weight, apgar score and intrapartum complications. Conclusion: In conclusion, although both Foley catheter and dinoprostone gel appear to be effective agents for cervical ripening. Foley catheter causes less fetal distress, cheap and safety profile of Foley catheter is such that it can be used on an out patient basis, but not dinoprostone gel. These results make Foley catheter comparable or even superior to dinoprostone gel for cervical ripening specially in developing countries.

Objective Cervical ripening by mechanical methods enhances labor induction success. We compared Cervical Ripening Double Balloon catheter (CRDB) to Foley catheter. Study design This prospective blind study randomized 85 nulliparas and 95 multiparas to labor induction by either Foley catheter or CRDB. Primary outcomes were Bishop score increment, time from catheter withdrawal to delivery, and cesarean section rate. Results In multiparas, mean Bishop score increment between pre- and post-catheter was significantly higher in the CRDB catheter than in the Foley group (4.4 ± 1.9 and 3.4 ± 2.0, respectively, p = .02). Mean interval from catheter withdrawal to delivery was shorter in the CRDB catheter (14.6 ± 12.3 and 8.6 ± 5.4) than in the Foley catheter group (22.6 ± 27.2 and 13.9 ± 17.7), in both nulliparas and multiparas (p = .05 and p = .03, respectively). In nulliparas, no statistically significant differences were found in mean Bishop score increment between the two catheters, but cesarean section rate was higher in the Foley group than the CRDB group (46.5% and 20%, respectively, p = .02). Conclusion Bishop score increment by CRDB catheter is more effective than induction by Foley catheter in multiparas. CRDB catheter is associated with decreased time to delivery in both nulliparas and multiparas and a lower cesarean section rate in nulliparas. ClinicalTrials.gov Identifier: NCT00501033

ABSTRACTIntroduction:Ureteroceles present a diagnostic and treatment challenge in adults (1). With an estimated prevalence of 1/500 to 1/4000, it is not uncommon for any urologist to encounter ureteroceles in clinical practice (2). The incidence of prolapsed ureteroceles in adults is unknown (3).Materials and Methods:We present an interesting case of a 53-year-old male with a 20-year history of obstructive voiding symptoms who presented with urinary retention with a Foley catheter in place. Pre-operative evaluation included a transrectal ultrasound of the prostate which revealing prostate volume of 20cc. Urodynamics revealed a high-pressure, low flow voiding pattern with a functional detrusor muscle. Cystourethroscopy was performed revealing an orthotopic ureterocele on the left side that was prolapsed into the prostatic urethra, and the bladder neck was elevated. The patient then underwent holmium laser ureterocele excision with transurethral incision of the prostate (TUIP). Using MOSES technology and laser settings of 30Hz and 1.5J, the ureterocele was completely excised and a TUIP was performed.Results:The patient was discharged home on the day of surgery with a Foley catheter in place. On post-operative day 1 he passed a voiding trial with a post-void residual volume of 25cc. Renal ultrasonography was performed 3 months postoperatively revealing no hydronephrosis. His postoperative International Prostate Symptom Score of 2 was improved compared to his preoperative score of 34.Conclusion:Holmium laser ureterocele excision with a TUIP is an effective treatment modality in the management of a prolapsed orthotopic ureterocele causing bladder outlet obstruction in a male patient.

Hyaluronidase versus Foley catheter for cervical ripening in high-risk term and post term pregnancies

Using conventional endoscope to perform endoscopic submucosal dissection (ESD) is difficult because of the one-handed operation and blind dissection caused by gravity. Poor visualization of the submucosal plane causes ESD to be associated with a high risk of bleeding and perforation. This study aimed to develop a novel ESD-assistive robot system and to evaluate its efficacy. A novel flexible auxiliary single-arm transluminal endoscopic robot (FASTER) was developed. A total of 36 artificial lesions in ex vivo porcine stomachs were removed using the FASTER-assisted ESD method (n = 18) and the conventional ESD method (n = 18). Lesions were 2cm or 4cm in diameter, located on the anterior and posterior walls of the antrum. Primary outcome measurements were dissection time and dissection speed. The dissection time in FASTER-assisted ESD was significantly shorter than that in conventional ESD (7min vs 13min, p = 0.012), mainly because of the faster dissection speed (148.6 vs 97.0 mm2/min, p = 0.002). The total procedure time in FASTER-assisted ESD was shorter than that in conventional ESD, but the difference was not significant (16min vs 24min, p = 0.252). Complete en bloc resection was achieved in all lesions. No perforations were detected. The FASTER exhibited the ability of regrasp, multidirectional traction, and proper tension control during ESD. FASTER significantly increased the dissection speed by providing proper traction and achieving good submucosal vision. This new device is expected to facilitate ESD in clinical practice.
