Robot-assisted surgery for the management of apical prolapse: a bi-centre prospective cohort study.

OBJECTIVE: Robot-assisted surgery is a recognised treatment for pelvic-organ prolapse. Many of the surgical subgroup outcomes for apical prolapse are reported together, leading to a paucity of homogenous data. DESIGN: Prospective observational cohort study (NCT01598467, clinicaltrials.gov) assessing outcomes for homogeneous subgroups of robot-assisted apical prolapse surgery. SETTING: Two European tertiary referral hospitals. POPULATION: Consecutive patients undergoing robot-assisted sacrocolpopexy (RASC) and supracervical hysterectomy with sacrocervicopexy (RSHS). METHODS: Anatomical cure (simplified Pelvic Organ Prolapse Quantification, sPOPQ, stage 1), subjective cure (symptoms of bulge), and quality of life (Pelvic Floor Impact Questionnaire, PFIQ-7). MAIN OUTCOME MEASURES: Primary outcome: anatomical and subjective cure. SECONDARY OUTCOMES: surgical safety and intraoperative variables. RESULTS: A total of 305 patients were included (RASC n = 188; RSHS n = 117). Twelve months follow-up was available for 144 (RASC 76.6%) and 109 (RSHS 93.2%) women. Anatomical success of the apical compartment occurred for 91% (RASC) and in 99% (RSHS) of the women. In all compartments, the success percentages were 67 and 65%, respectively. Most recurrences were in the anterior compartment [15.7% RASC (symptomatic 12.1%); 22.9% RSHS (symptomatic 4.8%)]. Symptoms of bulge improved from 97.4 to 17.4% (P < 0.0005). PFIQ-7 scores improved from 76.7 ± 62.3 to 13.5 ± 31.1 (P < 0.0005). The duration of surgery increased significantly for RSHS [183.1 ± 38.2 versus 145.3 ± 29.8 (P < 0.0005)]. Intraoperative complications and conversion rates were low (RASC, 5.3 and 4.3%; RSHS, 0.0 and 0.0%). Four severe postoperative complications occurred after RASC (2.1%) and one occurred after RSHS (1.6%). CONCLUSIONS: This is the largest reported prospective cohort study on robot-assisted apical prolapse surgery. Both procedures are safe, with durable results. TWEETABLE ABSTRACT: European bi-centre trial concludes that robot-assisted surgery is a viable approach to managing apical prolapse.

Da Vinci robot emergency undocking protocol.

The role of robot-assisted surgery across gynaecology is evolving with increasing numbers of procedures being undertaken with varying degrees of complexity. While the risk of conversion is low at approximately 1 %, the reasons for conversion are variable. These range from technical issues with the robot, surgical complications such as haemorrhage and anaesthetics issues such as an inability to ventilate the patient adequately. While many conversions to open or laparoscopic approach are not due to life-threatening indications, it is important that the theatre staff are aware of the indication and can perform an emergency undocking as effectively, efficiently and safely as possible when the need arises. Unfortunately, there is a paucity of the literature available outlining such protocols. For this reason, we developed an emergency undocking protocol clearly outlining the role of each theatre staff member and the need for clear concise communication.

The Effect of Bariatric Surgery on Urinary Incontinence in Women.

BACKGROUND: Little is known regarding the effect of bariatric surgery on urinary incontinence. METHODS: Between September 2008 and November 2014, 240 female patients underwent bariatric surgery. RESULTS: The prevalence of urinary incontinence preoperatively was 45 % (108). Eighty-two (76 %) completed urinary function questionnaires pre-operatively and post-operatively. Fifty-seven (70 %) underwent laparoscopic gastric bypass, twenty-four (29 %) underwent sleeve gastrectomy and one underwent a banding procedure. Thirty-one (38 %) reported leaking on sneezing or coughing-stress urinary incontinence (SUI). Thirteen (16 %) complained of leaking before reaching the toilet-overactive bladder syndrome (OAB). The remaining thirty-eight (46 %) reported mixed symptoms. The mean pre-operative weight and BMI were 133 (18) kg and 50 (SD = 6.2) kg/m(2) respectively. The mean post-operative BMI drop was 16 (SD = 5.2) kg/m(2). Preoperatively, 61 (75 %) reported moderate to very severe urinary incontinence compared to 30 (37 %) post-operatively (χ (2) = 3.24.67, p = 0.050). Twenty-seven (33 %) patients reported complete resolution of their urinary incontinence. Fifty-one (62 %) patients required incontinence pads on a daily basis pre-operatively, compared to 35 (43 %) post-operatively (χ (2) = 22.211.6, p = 0.00). The mean International Consultation on Incontinence Questionnaire- Urinary Incontinence short form (ICIQ-UI SF) score was 9.3 (SD = 4.4) pre-operatively compared to 4.9 (SD = 5.3) post-operatively (t = 7.2, p = 0.000). The improvement score post-operatively was 8 (SD = 3). A significant difference in the ICIQ-UI SF was identified between OAB and SUI groups when adjusting for age, number of children, type of delivery and pre-op BMI (t = 1.98, p = 0.05). CONCLUSION: Bariatric surgery results in a clinically significant improvement in urinary incontinence. However, this is not proportional to pre-operative BMI, weight loss, age, parity and mode of delivery.

Lightweight meshes: evaluation of mesh tissue integration and host tissue response.

INTRODUCTION: Differences in mesh composition may affect outcomes such as erosion, tissue integration and inflammation. The majority of commercially available meshes are type 1, manufactured from monofilament polypropylene with differing pore sizes and mechanical properties. OBJECTIVE: To assess the local tolerance of four commercially available meshes in terms of mesh integration and host tissue response. METHOD: Using an animal model, mesh was implanted onto the abdominal sheath. Animals were sacrificed at 7, 30 and 90 days and data collected. RESULTS: Strength of mesh-skin integration increased in all groups across the three time points. Polyform displayed highest strength of separation overall. VM PFR and Iprolite reached their maximum integration earliest. In regard to mesh abdominal wall integration Polyform had the greatest strength of separation, with Ultrapro displaying some weakening of integration at 30 and 90 days. Host tissue response was similar in all groups at each time point. CONCLUSION: Polyform and VM PFR have enhanced tissue integration when compared to Ultrapro. This decreased integration in Ultrapro may lead to increased mesh failure. The composition of mesh affects its integration and potentially its failure rate but not host tissue response. These observations in mesh characteristics may benefit the design of next generation meshes with a view to reducing failure rates and erosion.

Pregnancy complicated by portal hypertension secondary to biliary atresia.

Biliary atresia is a rare idiopathic neonatal cholestatic disease characterized by the destruction of both the intra- and extrahepatic biliary ducts. As the disease is progressive all cases will develop portal fibrosis, cirrhosis, and portal hypertension with the sequelae of varices, jaundice, and eventually liver failure requiring a transplant. Survival rates have improved considerably with many females living well in to be childbearing age. Due to the complexity of the disease these pregnancies are considered, high risk. We report the antenatal, intrapartum, and postpartum managements of a pregnancy complicated by biliary atresia. Furthermore, we highlight the importance of a multidisciplinary team approach in optimizing obstetric care for this high risk group.

Robot-assisted surgery:--impact on gynaecological and pelvic floor reconstructive surgery.

The da Vinci Surgical System dominates robotic surgery, as the only robotic device to have FDA approval in gynaecology. The benefits of robot-assisted surgery include decreased length of stay, decreased blood loss and analgesic requirements. Ergonomic improvements allow the surgeon to operate with less risk of neck and back injury. Unfortunately the initial economic impact of purchasing and maintaining a robot are great but must be balanced with the potential savings from reduced length of stay and earlier return to normal activity. This review looks at the uses for the robot in both gynaecology and urogynaecology, assessing the efficacy of this modality compared to both straight stick (laparoscopy) and open procedures. We assess the benefits to both patient and surgeon from the available literature. Within the current economic environment we appraise the costs associated with the robot.
