ABSTRACT

OBJECTIVE: To reach a Delphi-generated international expert consensus on the diagnosis, prognostic, management, and core outcome set (COS) of fetal Lower Urinary Tract Obstruction (LUTO). METHODS: A three-round Delphi procedure was conducted among an international panel of LUTO experts. The panel was provided with a list of literature review-generated parameters for the diagnosis, prognostic, management, and outcomes. A parallel procedure was conducted along with patient groups during the development of COS. RESULTS: A total of 160 experts were approached, of whom 99 completed the first round and 80 (80/99, 80.8%) completed all three rounds. In the first trimester, an objective measurement of longitudinal bladder diameter (with ≥7 mm being abnormal) should be used to suspect LUTO. In the second trimester, imaging parameters of LUTO could include: a) an enlarged bladder, b) a keyhole sign, c) bladder wall thickening, d) bilateral hydro (uretero) nephrosis, and e) male sex. There was a lack of consensus on the current prognostic scoring literature. However, experts agreed on the value of amniotic fluid volume (< 24 weeks) to predict survival and that the value of fetal intervention is to improve neonatal survival. While experts endorsed the role of sonographic parameters of renal dysplasia, at least one vesicocentesis, and urine biochemistry for prognosis and counseling, these items did not reach a consensus for determining fetal intervention candidacy. On the other hand, imaging parameters suggestive of LUTO, absence of life-limiting structural or genetic anomalies, gestational age of ≥16 weeks, and oligohydramnios defined as deepest vertical pocket (DVP) <2 cm should be used as candidacy criteria for fetal intervention based on experts' consensus. If a bladder refill was evaluated, it should be assessed subjectively. Vesicoamniotic shunt should be the first line of fetal intervention. In the presence of suspected fetal renal failure, serial amnioinfusion should only be offered as an experimental procedure under research protocols. The core outcome set for future studies was agreed upon. CONCLUSION: International consensus on the diagnosis, prognosis, and management of fetal LUTO, as well as the Core Outcome Set, should inform clinical care and research to optimize perinatal outcomes.

ABSTRACT

BACKGROUND: A number of serious human adenovirus (HAdV) outbreaks have been recently reported: HAdV-B7 (Israel, Singapore, and USA), HAdV-B7d (USA and China), HAdV-D8, -D54, and -C2 (Japan), HAdV-B14p1 (USA, Europe, and China), and HAdV-B55 (China, Singapore, and France). METHODS: To understand the epidemiology of HAdV infections in Singapore, we studied 533 HAdV-positive clinical samples collected from 396 pediatric and 137 adult patients in Singapore from 2012 to 2018. Genome sequencing and phylogenetic analyses were performed to identify HAdV genotypes, clonal clusters, and recombinant or novel HAdVs. RESULTS: The most prevalent genotypes identified were HAdV-B3 (35.6%), HAdV-B7 (15.4%), and HAdV-E4 (15.2%). We detected 4 new HAdV-C strains and detected incursions with HAdV-B7 (odds ratio [OR], 14.6; 95% confidence interval [CI], 4.1-52.0) and HAdV-E4 (OR, 13.6; 95% CI, 3.9-46.7) among pediatric patients over time. In addition, immunocompromised patients (adjusted OR [aOR], 11.4; 95% CI, 3.8-34.8) and patients infected with HAdV-C2 (aOR, 8.5; 95% CI, 1.5-48.0), HAdV-B7 (aOR, 3.7; 95% CI, 1.2-10.9), or HAdV-E4 (aOR, 3.2; 95% CI, 1.1-8.9) were at increased risk for severe disease. CONCLUSIONS: Singapore would benefit from more frequent studies of clinical HAdV genotypes to identify patients at risk for severe disease and help guide the use of new antiviral therapies, such as brincidofovir, and potential administration of HAdV 4 and 7 vaccine.

ABSTRACT

AIM: Our aim was to identify whether personality traits and decision-making styles affect quality of life (QoL) outcomes and levels of psychological distress following pelvic exenteration (PE). METHOD: Patients undergoing PE between 2008 and 2015 were identified from a prospectively maintained database at a single quaternary referral centre. Patients were invited to complete two validated questionnaires, with the Big Five inventory being used to assess personality traits and the Melbourne Decision Making Questionnaire to determine decision-making style. Data on QoL outcomes and distress from the prospectively established database were utilized. QoL with respect to both physical and mental health components was measured using Short Form 36 version 2 (SF-36v2) and the Functional Assessment of Cancer Therapy - Colorectal (FACT-C). Distress was measured using the Distress Thermometer. Postoperative pain scores were also measured using SF-36v2. RESULTS: Of the 93 patients eligible for participation, 42 returned the study questionnaire. On multivariate analysis, neuroticism was the most significant predictor of poorer QoL and increased levels of distress, consistent across all of the measures utilized and at the different time points used. Other personality traits showed an isolated statistically significant impact upon QoL. There were no significant findings with respect to decision-making style. Apart from neuroticism, the most significant predictor of QoL was the number of major complications for the patient. CONCLUSION: Patients demonstrating neurotic personality traits show poorer QoL outcomes and higher levels of distress following PE. Identification of these patients would allow targeted pre- and postoperative intervention to improve outcomes following PE.

ABSTRACT

AIM: The aim was to compare postoperative quality of life (QOL) between patients undergoing pelvic exenteration (PE) and pelvic exenteration with sacrectomy (PES), and to investigate the influence of high (L5-S2) vs low (≤ S3) sacrectomy on QOL and functional outcomes. METHOD: Patients undergoing en bloc sacrectomy as part of a PE and PE alone from 2008 to 2015 were identified from a prospectively maintained database. QOL and functional outcomes were assessed using the 36-Item Short Form Survey, the European Organization for Research and Treatment of Cancer Colorectal Cancer questionnaire and Quality of Life questionnaire, the Revised Musculoskeletal Tumour Scale, the Lower Extremity Functional Scale, the Sexual Health Inventory for Men and the Female Sexual Function Index. RESULTS: Of the 344 patients identified, data were available for 116 patients who underwent PE alone and 140 patients who underwent PES. PES patients had significantly poorer physical component scores (P < 0.001) but not mental component scores (P = 0.17). Of the 140 PES patients, 55 were eligible and were invited to participate in a second functional survey, with 30 patients returning the study questionnaire. High sacrectomy patients, compared with low sacrectomy, had significantly worse lower limb motor function (P = 0.03) and poorer physical (P = 0.001) and mental health component scores (P = 0.02). No differences were found in sexual, bladder and bowel function between high and low sacrectomy patients. CONCLUSIONS: Patients undergoing PES had worse physical component scores compared with PE alone, whereas high sacrectomy patients had significantly worse lower limb motor function and physical and mental component scores but comparable bowel, bladder and sexual functional outcomes compared with low sacrectomy patients.

ABSTRACT

Together with isocitrate dehydrogenase (IDH) mutation, co-deletion of 1p19q (1p19q codel) is a prerequisite for diagnosis of oligodendroglioma, making it imperative that histopathology laboratories introduce testing for 1p19q codel. To date there is still no consensus reference range and cut-offs that confirm deletion of 1p or 19q. We embarked on determining our reference range in 11 formalinfixed, paraffin-embedded non-neoplastic brain tissue using fluorescence in situ hybridisation (FISH) with the Vysis 1p36/1q25 and 19q13/19p13 FISH Probe Kit (Abbott Molecular Inc., USA). At same time we attempted to validate our methodology in 13 histologically-confirmed IDH-mutant oligodendrogliomas. For 1p, percentage cells with deletion (range=8-23%; mean±SD = 15.73±5.50%) and target: control (1p36:1q25) ratio (range = 0.89-0.96; mean±SD = 0.92±0.03) in non-neoplastic brain, differed significantly (p<0.000) from oligodendroglioma (percentage cells with deletion: range = 49-100%; mean±SD = 82.46±15.21%; target:control ratio range:0.50-0.76; mean±SD = 0.59±0.08). For 19q, percentage cells with deletion (range = 7-20%; mean±SD = 12.00±3.49%) and target:control (19q13/19p13) ratio (range:0.90-0.97; mean±SD = 0.94±0.02) in non-neoplastic brain also differed significantly from oligodendroglioma (percentage cells with deletion: range = 45-100%; mean±SD = 82.62±18.13%; target:control ratio range:0.50-0.78; mean±SD = 0.59±0.09). Using recommended calculation method, for diagnosis of 1p deletion, percentage of cells showing deletion should be >32-33% and/or target:control ratio <0.83. For 19q, percentage of cells showing deletion should be >22% and target:control ratio <0.88. Using these cut-offs all 13 oligodendroglioma demonstrated 1p19q codel.

ABSTRACT

BACKGROUND: Pelvic exenteration (PE) provides a potentially curative option for advanced or recurrent malignancy confined to the pelvis. A clear (R0) resection margin is the strongest prognostic factor predicting long-term survival, driving most technical advances in PE surgery. The aim of this cohort study was to describe changing trends in extent of resection, postoperative complications, mortality and overall survival after PE surgery. METHODS: Consecutive patients who underwent PE for advanced or recurrent pelvic malignancy at a single institution in Sydney, Australia, were identified. The cohort was divided into three groups based on time periods reflecting annual surgical volume: 1994-2006 (20 or fewer procedures per year), 2007-2013 (21-50 procedures per year) and 2014-2017 (over 50 procedures per year). Primary outcomes were extent of resection, postoperative complications, 60-day mortality and 3-year overall survival. Secondary outcomes were patient characteristics, receipt of neoadjuvant therapy and duration of hospital stay. RESULTS: There were increases over time in rates of lateral and posterior compartment resections (P < 0·001), and bony pelvis (P = 0·002) and neurovascular (P < 0·001) excision. For patients undergoing reconstruction, the proportion receiving vertical rectus abdominus myocutaneous flaps increased significantly (P = 0·005). Rates of wound infection, dehiscence, and abdominal and pelvic collections increased over the study interval. Short-term mortality decreased, and 1- and 3-year survival rates improved. CONCLUSION: Technical and surgical advancements have led to more complex PE resections, with R0 and mortality rates improving with higher annual volume. There were associated increases in intraoperative blood loss and postoperative morbidity.


ANTECEDENTES: La exenteración pélvica (pelvic exenteration, PE) ofrece una opción potencialmente curativa para el cáncer localmente avanzado o la recidiva de la neoplasia limitada a la pelvis. Un margen de resección libre (R0) es el factor pronóstico más importante que predice la supervivencia a largo plazo, lo que ha impulsado la mayoría de los avances técnicos en la cirugía de la PE. El objetivo de este estudio de cohortes fue describir el cambio en la tendencia relativa a la extensión de la resección, las complicaciones postoperatorias, la mortalidad y la supervivencia global después de la cirugía de la PE. MÉTODOS: Se identificaron pacientes intervenidos de forma consecutiva a los que se practicó una PE por neoplasia pélvica avanzada o recidivante en una sola institución en Sydney, Australia. La cohorte se dividió en tres grupos según períodos de tiempo que reflejan el volumen quirúrgico anual: 1994-2006 (≤ 20 casos por año), 2007-2013 (21-50 casos por año) y 2014-2017 (> 50 casos por año). Los criterios de valoración principal fueron la extensión de la resección, las complicaciones postoperatorias, la mortalidad a los 60 días y la supervivencia a los tres años. Los criterios de valoración secundarios fueron las características del paciente, la administración de tratamiento neoadyuvante y la duración de la estancia hospitalaria. Las tendencias se evaluaron mediante pruebas de χ2 o ANOVA de una vía. RESULTADOS: Los porcentajes de resección de los compartimentos lateral y posterior, pelvis ósea así como de escisión neurovascular aumentaron con el tiempo (P < 0,01). Entre los pacientes en los que se hizo una reconstrucción, el porcentaje de colgajos miocutáneos verticales del recto del abdomen aumentó significativamente (P = 0,005). Las tasas de infección de herida, dehiscencia y colecciones abdominales y pélvicas aumentaron durante el período de estudio. La mortalidad a corto plazo disminuyó y la supervivencia a 1 y 3 años mejoró durante el período de estudio. CONCLUSIÓN: Los avances técnicos y quirúrgicos han permitido realizar resecciones de PE más complejas, mejorando las tasas de resección R0 y de mortalidad al aumentar el volumen anual de intervenciones. Al mismo tiempo se han observado incrementos en las pérdidas intraoperatorias de sangre, en las reconstrucciones y en la morbilidad postoperatoria.

ABSTRACT

BACKGROUND: Despite advances in the rates of total mesorectal excision (TME) for rectal cancer surgery, decreased local recurrence rates and increased 5-year survival, there still exists large variation in the quality of treatment received. Up to 30 per cent of rectal cancers are locally advanced at presentation and approximately 5-10 per cent still breach the mesorectal plane and invade adjacent structures despite neoadjuvant therapy. With the evolution of extended resections for rectal cancers beyond the TME plane, proponents advocate that these resections should be performed only in specialist centres. The aim was to assess the prognostic factors and patterns of failure after beyond TME surgery for T4 rectal cancers. METHODS: Data were collected from prospective databases at three high-volume institutions specializing in beyond TME surgery for T4 rectal cancers between 1990 and 2013. The primary outcome measures were overall survival, local recurrence and patterns of first failure. RESULTS: Three hundred and sixty patients were identified. The negative resection margin (R0) rate was 82·8 per cent (298 patients) and the local recurrence rate was 12·5 per cent (45 patients). The type of surgical procedure (Hartmann's: hazard ratio (HR) 4·49, 95 per cent c.i. 1·99 to 10·14; P = 0·002) and lymphovascular invasion (HR 2·02, 1·08 to 3·77; P = 0·032) were independent predictors of local recurrence. The 5-year overall survival rate for all patients was 61 (95 per cent c.i. 55 to 67) per cent. The 5-year cumulative incidence of first failure was 8 per cent for local recurrence, 6 per cent for local and distant disease, and 18 per cent for distant disease. CONCLUSION: This study has demonstrated that a coordinated approach in specialist centres for beyond TME surgery can offer good oncological and long-term survival in patients with T4 rectal cancers.


ANTECEDENTES: A pesar de las mejoras en los porcentajes de extirpación total del mesorrecto (total mesorectal excision, TME) en la cirugía de cáncer de recto, la disminución de los porcentajes de recidiva local y el aumento de la supervivencia a 5 años, todavía existe una gran variabilidad en la calidad del tratamiento recibido. Hasta el 30% de los cánceres de recto están localmente avanzados en el momento del diagnóstico y aproximadamente el 5-10% sobrepasarán el plano mesorrectal e invadirán las estructuras adyacentes a pesar del tratamiento neoadyuvante. Con la evolución de las resecciones ampliadas para los cánceres de recto que sobrepasan el plano de la TME, los defensores recomiendan que estas resecciones solo se realicen en centros especializados. El objetivo fue evaluar los factores pronósticos y los patrones de recidiva después de la cirugía ampliada más allá de la TME para los cánceres de recto T4. MÉTODOS: Los datos se recogieron a partir de bases de datos prospectivas de tres instituciones de alto volumen especializadas en resecciones ampliadas más allá de la TME para el cáncer de recto T4 entre 1990 y 2013. Los criterios de valoración principal fueron la supervivencia global, la recidiva local y los patrones de la primera recidiva. RESULTADOS: Se identificaron 360 pacientes. El margen de resección fue negativo (R0) en el 82,8% (n = 298) y el porcentaje de recidiva local fue de 12,5% (n = 45). El tipo de cirugía realizada (Hartmann: cociente de riesgos instantáneos, hazard ratio, HR 4,49; i.c. del 95%: 1,99-10,14; P = 0,002) y la invasión linfovascular (HR 2,02; i.c. del 95%: 1,08-3,77; P = 0,032) fueron factores predictivos independientes de recidiva local. La supervivencia global a 5 años para todos los pacientes fue del 61% (i.c. del 95%: 55-67). La incidencia acumulada a los 5 años de la primera recidiva fue de 8% para la recidiva local, 6% para la recidiva local y a distancia, y 18% para la recidiva a distancia. CONCLUSIÓN: Este estudio demuestra que un abordaje coordinado en centros especializados para cirugía más allá de la TME puede ofrecer una buena supervivencia oncológica y a largo plazo en pacientes con cáncer de recto T4.

ABSTRACT

OBJECTIVE: Congenital lower urinary tract obstruction (LUTO) is a rare condition with high perinatal mortality and morbidity when associated with severe oligohydramnios or anhydramnios in the second trimester of pregnancy. Severe pulmonary hypoplasia and end-stage renal disease are the underlying causes of poor neonatal outcome in these cases. However, little is known about the subset of fetal LUTO that is associated with a normal volume of amniotic fluid at midgestation. The objective of the current study was to describe the natural history, underlying causes, survival and postnatal renal function outcomes in pregnancies with fetal LUTO and normal amniotic fluid volume during the second trimester of pregnancy. METHODS: This was a retrospective study of all pregnancies with fetal LUTO and normal amniotic fluid volume in the second trimester that received prenatal and postnatal care at our quaternary care institution between 2013 and 2017. Data on demographic characteristics, fetal interventions, perinatal survival, need for neonatal respiratory support, postnatal renal function and need for dialysis at the age of 1 and 24 months were analyzed. RESULTS: Of the 18 fetuses that met the study criteria, 17 (94.4%) survived the perinatal period. Eleven (61.1%) pregnancies developed oligohydramnios in the third trimester, six of which were eligible for and underwent fetal intervention with vesicoamniotic shunt placement, which was performed successfully in all six cases. Two (11.1%) neonates required respiratory support owing to pulmonary hypoplasia. At the age of 2 years, 14 children had follow-up information available, two (14.3%) of whom had normal renal function, eight (57.1%) had developed some degree of chronic kidney disease (Stage 1-4) and four (28.6%) had developed end-stage renal disease (ESRD), including two who had already manifested ESRD in the neonatal period. CONCLUSIONS: Most fetuses diagnosed prenatally with LUTO that is associated with a normal volume of amniotic fluid at midgestation will have a favorable outcome in terms of perinatal survival and few will need long-term respiratory support. However, these children are still at increased risk for chronic renal disease, ESRD and need for renal replacement therapy. Larger multicenter studies are needed to characterize the prenatal factors associated with postnatal renal function, and to investigate the role of fetal intervention in the group of fetuses that present with late-onset oligohydramnios and evidence of preserved fetal renal function.

ABSTRACT

AIM: Low anterior resection syndrome (LARS) can affect up to 70% of all patients with rectal cancer. In the last two decades, sacral nerve stimulation (SNS) has emerged as an effective treatment for faecal incontinence. There is some encouraging literature on the use of SNS in patients with LARS. The purpose of this review is to provide an up to date review on the utility of SNS on LARS. METHOD: A literature search was conducted using the MEDLINE, Embase and PubMed databases (January 1981-March 2019). Studies identified were appraised with standard selection criteria. Data points were extracted, and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RESULTS: Ten studies met the inclusion criteria and were included in this study. All studies used the Cleveland Clinic Incontinence Score (CCIS), whereas the low anterior resection syndrome score (LARS score) was used in three studies. Overall median improvement in the scoring system was 67.0% (range 35.5%-88.2%) after SNS implantation. There was a significant reduction in CCIS after SNS implantation (mean difference 11.23, 95% confidence interval 9.38-13.07, Z = 11.90, P < 0.00001). The LARS score was also significantly reduced after using SNS in patients with LARS (mean difference 17.87, 95% confidence interval 10.15-25.59, Z = 4.54, P < 0.00001). CONCLUSION: Use of SNS may provide symptomatic benefits for patients with LARS refractory to medical therapy. However, the current level of evidence remains limited. A large multicentre study of SNS for LARS using the validated LARS score is warranted. In addition, the cost-effectiveness of SNS for patients with LARS needs further exploration.

ABSTRACT

AIM: We compared the vaccine effectiveness of monovalent and combination hepatitis B vaccine regimens in infants born to chronic hepatitis B carrier mothers. METHODS: An observational cohort of neonates was recruited over 78 months from two public hospital maternity units in Singapore. We enrolled term infants, born to chronic hepatitis B surface antigen-positive mothers regardless of their hepatitis Be antigen status, who completed the hepatitis B virus (HBV) vaccination programme in Singapore. Infants born to mothers on antiviral therapy, or with concurrent hepatitis C or human immunodeficiency virus infection were excluded. All infants received hepatitis B immunoglobulin at birth. One group received three doses of monovalent hepatitis B vaccine (0, 1, 6 months) (regimen A). The other group received two doses of monovalent vaccine, followed by one dose combination vaccine DTaP-IPV-Hib-HBV (0, 1, 6 months) (regimen B). Vaccine effectiveness was determined by immunoprophylaxis failure leading to HBV vertical transmission. Immunogenicity was assessed by hepatitis B surface antibody (anti-HBs) levels at 9 months of age. RESULTS: Total of 177 term neonates received regimen A and 115 received regimen B. Immunoprophylaxis failure rate was low, 2.3 and 2.6% (P = 1.00) in regimen A and B, respectively. Mean anti-HBs titres were similar at 643 ± 374 and 561 ± 396 IU/L (P = 0.08) for regimen A and B, respectively. CONCLUSION: Hepatitis B vaccine regimens using monovalent or combination vaccine for the third dose showed similarly high vaccine effectiveness and low immunoprophylaxis failure rate in term infants born to chronic hepatitis B carrier mothers.

ABSTRACT

Since 2014, the National Comprehensive Cancer Network (NCCN) has recommended that colorectal carcinoma (CRC) be universally tested for high microsatellite instability (MSI-H) which is present in 15% of such cancers. Fidelity of resultant microsatellites during DNA replication is contingent upon an intact mismatch repair (MMR) system and lack of fidelity can result in tumourigenesis. Prior to commencing routine screening for MSI-H, we assessed two commonly used methods, immunohistochemical (IHC) determination of loss of MMR gene products viz MLH1, MSH2, MSH6 and PMS2 against PCR amplification and subsequent fragment analysis of microsatellite markers, BAT25, BAT26, D2S123, D5S346 and D17S250 (Bethesda markers) in 73 unselected primary CRC. 15.1% (11/73) were categorized as MSI-H while deficient MMR (dMMR) was detected in 16.4% (12/73). Of the dMMR, 66.7% (8/12) were classified MSI-H, while 33.3% (4/12) were microsatellite stable/low microsatellite instability (MSS/MSI-L). Of the proficient MMR (pMMR), 95.1% (58/61) were MSS/MSI-L and 4.9% (3/61) were MSI-H. The κ value of 0.639 (standard error =0.125; p = 0.000) indicated substantial agreement between detection of loss of DNA mismatch repair using immunohistochemistry and the detection of downstream microsatellite instability using PCR. After consideration of advantages and shortcomings of both methods, it is our opinion that the choice of preferred technique for MSI analysis would depend on the type of laboratory carrying out the testing.

ABSTRACT

We report an Elizabethkingia anophelis case cluster associated with contaminated aerators and tap water in a children's intensive care unit in Singapore in 2017. We demonstrate a likely transmission route for E. anophelis to patients through acquisition of the bacteria on hands of healthcare workers via handwashing.

ABSTRACT

OBJECTIVE: Needs assessment is the essence of quality cancer survivorship care. The aim of this study was to explore the supportive care needs of breast cancer survivors (BCS) in the first 5 years post treatment. METHODS: A mixed-methods approach was employed. A quantitative study included a Supportive Care Needs Survey, which was completed by 250 BCS to identify the level of their needs for help. The quantitative data informed semistructured qualitative interviews undertaken with 60 BCS to explore in detail their posttreatment needs and experiences. RESULTS: 32.4% and 16.8% reported 1 to 5 and greater than or equal to 6 needs for help, respectively. The regression analyses revealed that women within 2 years posttreatment and with higher educational level had higher levels of Psychological and Health Care System/Information needs. The qualitative data revealed "continuity of care" and "lifestyle advice and self-management" as prominent survivorship concerns. It was shown that determination to continue normal life, social support, and feeling overwhelmed by information were all experienced as important influences on survivors' need for help. CONCLUSIONS: Posttreatment needs vary with BCS characteristics and to the domains concerned. The approach to posttreatment care needs to be personalized and viable.

ABSTRACT

AIM: Biofeedback is an established, effective and non-invasive treatment for faecal incontinence (FI). The aim was to compare the effectiveness of four different biofeedback treatment regimes. METHOD: This was a randomized control trial of patients with FI, stratified into two groups (metropolitan and rural) and then randomized into two subgroups (groups 1 and 2 within metropolitan, groups 3 and 4 within rural) with varying face-to-face and telephone biofeedback components. All patients received standardized counselling and education, dietary modification and the use of anti-diarrhoeal medications. Group 1 received four monthly face-to-face biofeedback treatments, groups 2 and 3 received one face-to-face biofeedback followed by telephone biofeedback and group 4 received a one-off face-to-face biofeedback treatment. Primary outcomes were patient-assessed severity of FI and quality of life as assessed by the 36-item Short Form Health Survey and direct questioning of objectives. Secondary outcomes included St Mark's incontinence score, anxiety, depression and anorectal physiology measures (resting, squeeze pressures; isotonic, isometric fatigue times). RESULTS: Between 2006 and 2012, 351 patients were recruited. One patient died leaving 350 for analysis. 332 (95%) were women. Mean age was 60 (SD = 14). All groups had significant improvements in FI, quality of life, incontinence score and mental status (P < 0.001 each). There were no differences in improvements in FI between groups although patient satisfaction was less with reduced face-to-face contact. There were modest improvements in isotonic and isometric fatigue times suggesting improved sphincter endurance (both P < 0.001). CONCLUSION: Biofeedback is effective for FI. Although face-to-face and telephone biofeedback is not necessary to improve FI, it is important for patient satisfaction.

ABSTRACT

BACKGROUND: Returning to the operating theatre for management of early postoperative complications after colorectal surgery is an important key performance indicator. Laparoscopic surgery has benefits that may be useful in surgical emergencies. This study explored the evidence for the advantages of laparoscopic reoperation. METHODS: A systematic review was performed to identify publications reporting the outcomes of laparoscopy as a mode of reoperation for the management of early postoperative complications of colorectal surgery. The main outcomes examined were 30-day mortality, 30-day morbidity, length of hospital stay, second reoperation rate, ICU admission and stoma formation at reoperation. RESULTS: After screening 3657 citations, ten non-randomized cohort studies were identified (1137 reoperations). Laparoscopic reoperation was equivalent to or better than open reoperation, with lower rates of 30-day mortality (0-4·4 versus 0-13·6 per cent), 30-day morbidity (6-40 versus 30-80 per cent), length of stay (mean(s.d.) 15·8(2·8) versus 29·1(14·5) days), ICU admission and duration of stay in the ICU. Anastomotic leak was the most common indication, after which more patients received a defunctioning loop stoma instead of an end stoma at laparoscopic than open reoperation. CONCLUSION: Laparoscopic reoperation is feasible in selected patients, with the advantages of improved short-term outcomes.

ABSTRACT

BACKGROUND: Robotic ventral mesh rectopexy (RVMR) is an appealing approach for the treatment of rectal prolapse and other conditions. The aim of this study was to evaluate the outcomes of RVMR for rectal prolapse. METHODS: We performed a retrospective chart review for patients who underwent RVMR for rectal prolapse at our institution between July 2012 and May 2016. Any patient who underwent RVMR during this time frame was included in our analysis. Any cases involving colorectal resection or other rectopexy techniques were excluded. RESULTS: Of the 24 patients who underwent RVMR, 95.8% of patients were female. Median age was 67.5 years old (IQR 51.5-73.3), and 79.2% of patients were American Society of Anesthesiologists class III or IV. Median operative time was 191 min (IQR 164.3-242.5), and median length of stay was 3 days (IQR 2-3). There were no conversions, RVMR-related complications or mortality. Patients were followed for a median of 3.8 (IQR 1.2-15.9) months. Full-thickness recurrence occurred in 3 (12.4%) patients. Rates of fecal incontinence improved after surgery (62.5 vs. 41.5%, respectively) as did constipation (45.8 vs. 33.3%, respectively). No patients reported worsening symptoms postoperatively. Only one (4.2%) patient reported de novo constipation postoperatively. CONCLUSIONS: RVMR is a feasible, safe and effective option for the treatment of rectal prolapse, with low short-term morbidity and mortality. Multicenter and long-term studies are needed to better assess the benefits of this procedure.

ABSTRACT

Over the years, adenocarcinoma (ADC), which has a worse prognosis than squamous cell carcinoma (SCC) of the cervix, has shown an increasing trend. Cyclooxygenase-2 (COX2) expression which has been associated with worse prognosis in several solid cancers was studied for its association with SCC and ADC of the cervix. 35 histologically re-confirmed SCC and 35 ADC were immunohistochemically stained for COX2 using a mouse monoclonal antibody to COX2 (1:100; Dako: Clone CX-294) on a Ventana Benchmark XT. The histoscore was computed as intensity of staining, semi-quantitated on a scale of 0-3 with 0 = negative, 1 = weak, 2 = moderate and 3 = strong staining intensity; multiplied by percentage of immunopositivity on a scale of 0-4 with 0 = <1%, 1 = 1-25%, 2 = 26-50%, 3 = 51-75% and 4 = ≥75% of immunopositive tumour cells. Histoscore 1-3/12 was considered as low and ≥4/12 as high COX2 expression. SCC affected Chinese more than Malays, while Malays had more ADC (p = 0.032). Mean age at presentation of SCC (57.5 years) was about a decade later than ADC at 47.9 years (p = 0.002). 30/35 (85.7%) of SCC and 34/35 (97.1%) of ADC expressed COX2. Histoscores of ADC (median = 4.0, IQR = 3.0-6.0) was significantly higher (p = 0.014) than those of SCC (median = 3.0, IQR = 2.0-3.0). High histoscores (≥4/12) were more frequent in ADC (55.9%) compared with SCC (26.7%) (p = 0.018), implicating COX2, either directly or indirectly, as a possible player in influencing the poorer outcome of ADC compared with SCC.

ABSTRACT

STUDY QUESTION: Which essential items should be recorded before, during and after endometriosis surgery and in clinical outcome based surgical trials in patients with deep endometriosis (DE)? SUMMARY ANSWER: A DE surgical sheet (DESS) was developed for standardized reporting of the surgical treatment of DE and an international expert consensus proposal on relevant items that should be recorded in surgical outcome trials in women with DE. WHAT IS KNOWN ALREADY: Surgery is an important treatment for symptomatic DE. So far, data have been reported in such a way that comparison of different surgical techniques is impossible. Therefore, we present an international expert proposal for standardized reporting of surgical treatment and surgical outcome trials in women with DE. STUDY DESIGN, SIZE, DURATION: International expert consensus based on a systematic review of literature. PARTICIPANTS/MATERIALS, SETTING, METHODS: Taking into account recommendations from Consolidated Standards of Reporting Trials (CONSORT), the Innovation Development Exploration Assessment and Long-term Study (IDEAL), the Initiative on Methods, Measurement and Pain Assessment in Clinical trials (IMMPACT) and the World Endometriosis Research Foundation Phenome and Biobanking Harmonisation Project (WERF EPHect), a systematic literature review on surgical treatment of DE was performed and resulted in a proposal for standardized reporting, adapted by contributions from eight members of the multidisciplinary Leuven University Hospitals Endometriosis Care Program, from 18 international experts and from audience feedback during three international meetings. MAIN RESULTS AND THE ROLE OF CHANCE: We have developed the DESS to record in detail the surgical procedures for DE, and an international consensus on pre-, intra- and post-operative data that should be recorded in surgical outcome trials on DE. LIMITATIONS, REASONS FOR CAUTION: The recommendations in this paper represent a consensus among international experts based on a systematic review of the literature. For several items and recommendations, high-quality RCTs were not available. Further research is needed to validate and evaluate the recommendations presented here. WIDER IMPLICATIONS OF THE FINDINGS: This international expert consensus for standardized reporting of surgical treatment in women with DE, based on a systematic literature review and international consensus, can be used as a guideline to record and report surgical management of patients with DE and as a guideline to design, execute, interpret and compare clinical trials in this patient population.

ABSTRACT

BACKGROUND: The rising cost of healthcare is well documented. The purpose of this study was to determine the cost-effectiveness of pelvic exenteration (PE). METHODS: Consecutive patients referred for consideration of PE between 2008 and 2011 were recruited into a prospective non-randomized study that compared quality of life (QoL) between patients who did or did not undergo PE. Information on QoL and cost (in Australian dollars, AUD) was collected at baseline, during admission and up to 24 months after discharge. QoL data were converted into a utility-based measure. Quality-adjusted life-years (QALYs) were calculated. Bottom-up costing was performed. The incremental cost-effectiveness ratio (ICER) was calculated per life-year saved and per QALY. RESULTS: There were 174 patients with sufficient data for analysis. Of these, 139 underwent PE. R0 was achieved in 78·4 per cent of patients. The survival rate at 24 months after PE was 74·8 per cent compared with 43 per cent in those without exenteration (P = 0·001). Treatment costs were significantly higher for patients who had PE compared with those who did not (mean AUD 137 407 versus 79 174; P < 0·001). The ICER was AUD 124 147 (95 per cent c.i. 71 585 to 261 876) per life-year saved and AUD 227 330 (109 974 to 1 100 449) per QALY. Curative PE (R0) was found to be more cost-effective than non-curative PE (R1/R2), with an ICER of AUD 101 518 (60 105 to 200 428) versus 390 712 (74 368 to 82 256 739) per life-year saved. CONCLUSION: Treatment of advanced pelvic cancers is expensive regardless of the treatment intent. For a cost difference of only AUD 58 000 (€38 264), PE offers a chance of cure, and improves survival and QoL.

ABSTRACT

OBJECTIVE: To present a single center experience of a standardized prenatal multidisciplinary management protocol for fetal lower urinary tract obstruction (LUTO) and to propose a classification of fetal LUTO based on disease severity. METHODS: This was a retrospective cohort study of 25 consecutive fetal patients with prenatal diagnosis of primary LUTO. Fetal intervention was offered after evaluation by a multidisciplinary team. Analyses were conducted using Bayesian methodology to determine predictors of survival at 6 months postpartum. Odds ratios (ORs) with 95% credibility intervals are reported. RESULTS: Fifteen (60.0%) of the 25 patients referred for assessment survived to postnatal evaluation. Fetal vesicoamniotic shunt was placed in 14 (56.0%) patients with 12 survivors. Multivariable analysis suggested that fetal intervention (OR, 6.97 (0.88-70.16), Pr(OR > 1) = 96.7%), anhydramnios (OR, 0.12 (0.04-0.35), Pr(OR < 1) = 99.9%), favorable fetal urine analysis (OR, 3.98 (0.63-25.15), Pr(OR > 1) = 92.7%) and absence of renal cortical cysts (OR, 3.9 (0.66-24.2), Pr(OR > 1) = 93.3%) were predictors of survival. CONCLUSIONS: Fetal intervention and fetal renal function were independently associated with postnatal survival of fetuses with LUTO. A classification based on the severity of disease is proposed.
