Low anterior resection syndrome following rectal cancer surgery: are incidence and severity lower with long-term follow-up?

BACKGROUND: Low anterior resection syndrome (LARS) is a functional disorder that may follow restorative proctectomy. The aim of this study was to evaluate the long-term incidence and risk factors for LARS following surgery for rectal cancer. METHODS: A retrospective study was performed on patients from a prospectively maintained database, who underwent a restorative proctectomy between January 2014 and December 2019 at Hadassah Hebrew University Medical Center. The study cohort was divided into two groups: patients following partial proctectomy with a partial mesorectal excision and a colorectal anastomosis (PME group) and patients following total proctectomy with total mesorectal excision and a coloanal anastomosis (TME group). The incidence and severity of LARS were evaluated using the LARS questionnaire. Risk factors for LARS were also evaluated. RESULTS: A total of 240 patients (male: female ratio 134:106, median age 64 years [interquartile range 55-71 years]) were included in the analysis. There were 160 patients in the PME group and 80 patients in the TME group. The overall incidence of LARS was 37.4% (26.5% major LARS and 10.9% minor LARS). Major LARS was observed in 53.8% of patients who underwent TME and in 12.7% of patients who underwent PME (p < 0.001). On multivariate analysis, distance of the anastomosis from the anal verge, TME, and neoadjuvant radiotherapy were independent prognostic factors for LARS. The incidence and severity of LARS were significantly lower in patients with longer follow-up (p = 0.05). CONCLUSIONS: Significant improvement in LARS can be expected with longer follow-up. Distance of the anastomosis from the anal verge, TME and neoadjuvant radiotherapy are independent risk factors for LARS.

Long-term efficacy of Paula method as compared with pelvic floor muscle training for stress urinary incontinence in women: a 6-month follow-up.

PURPOSE: The purpose of this study was to examine the long-term efficacy of an exercise regimen based on circular muscle strengthening (Paula method) as opposed to pelvic floor muscle training (PFMT) on stress urinary incontinence symptoms at 6 months postintervention. SUBJECTS AND SETTING: Of 240 women who had initially participated in a randomized clinical trial, 143 women suffering from stress urinary incontinence participated in this follow-up study. METHODS: Subjects participated in a randomized controlled clinical trial comparing 2 exercise programs (12 private Paula lessons vs 6 group PFMT lessons) over a 12-week period. Of these, 143 women took part in the follow-up study: 64 from the Paula group and 79 from the PFMT group. Six-month follow-up data were gathered via telephone interviews. RESULTS: No significant deterioration in stress urinary incontinence symptoms occurred 6 months after completion of the interventions in either group. We found a statistically significant difference between the groups with regard to reported frequency of urinary leakage; 25 of subjects (39.7%) allocated to the Paula method reported a low frequency rate of incontinence episodes upon completion of the study as compared to 18 (22.8%) in the PFMT group (P = .03). Forty-nine of the 64 women in the Paula group (76.6%) and 62 of the 79 women in the PFMT group (78.5%) reported that they continued exercising 6 months after completion of the trial (P = .8). CONCLUSIONS: Both intervention methods reduced frequency of urinary incontinence over a 6-month period. Long-term adherence was similar in both groups. Pelvic floor muscle training was associated with fewer sessions and decreased cost and fewer lessons needed as compared with the Paula method. Nevertheless, results also suggest that the Paula method achieves a lower frequency of urinary leakage than PFMT.

Concordance between one-hour pad test and subjective assessment of stress incontinence.

OBJECTIVES: To examine the concordance among the 1-hour pad test results, subjective questions regarding incontinence, and a quality-of-life questionnaire to assess the role of the pad test as a noninvasive measurement tool in clinical trials. The 1-hour nonstandard pad test is one of several quantitative tools used to measure urinary incontinence; however, its utility has been questioned. METHODS: The study subjects were women participating in 2 clinical trials evaluating noninvasive interventions: circular muscle exercises versus pelvic floor muscle training for urinary incontinence. The quantity of urinary leakage according to the pad test and questions regarding subjective urinary leakage from the quality-of-life questionnaire were evaluated for all study subjects combined and in subgroups. RESULTS: A total of 731 clinical pad tests were evaluated from the 2 trials. Significant associations were found between several questions regarding subjective leakage and the pad test results in the study subgroups. A significant correlation was seen between the pad test results and the quality-of-life questionnaire scores (r = 0.14 before intervention and r = 0.42 after intervention in the combined studies; P < .05). CONCLUSIONS: The 1-hour pad test demonstrated concordance with subjective assessment tools for urinary incontinence and should be considered a part of the armamentarium for assessing the severity of this condition.

Randomized trial of circular muscle versus pelvic floor training for stress urinary incontinence in women.

BACKGROUND: Conservative management, such as pelvic floor muscle training (PMFT), is commonly recommended as first-line therapy for women with stress urinary incontinence (SUI). METHODS: We randomly assigned 245 women with SUI to 12 weeks of circular muscle exercises (Paula method) or PMFT in order to assess whether these approaches are equivalent. End points after 12 weeks included urinary leak as measured by a 1-hour pad test, subjective assessment of incontinence, and quality of life (QOL). Cure was defined as urinary leakage of <1 g. RESULTS: The mean decrease in urinary leakage was 7.9 g (SD 12.1) among women in the Paula group and 8.9 g (SD 18.2) in the PFMT group (90% confidence interval [CI] of between-group difference was -4.68 g to 3.0 g). This did not meet the prespecified criterion for equivalence. There were 15.2% (p = 0.04) more cures in those randomized to the Paula method. Improvement in subjective urinary complaints and QOL was observed in both groups. The study was limited by a dropout rate of 26.6%. CONCLUSIONS: Both methods are efficacious in women with SUI. The results suggest superiority of the Paula method in terms of cure rate.

The use of a perinatal internet consultation forum in Israel.

To analyse the use of a free, public, perinatal internet consultation service, 2000 consultations provided by university hospital staff were evaluated over 30 months. Ninety five percent of the questioners were women, and 62% of them were primiparous. The average response rate was 2.3 audience responses per question. Fifty-two percent of the consultations were related to labour and delivery, 23% were related to pregnancy complications, 16% were related to prenatal diagnosis, and 7% were related to the puerperium period. We conclude that medical consultation forums provide an additional way of delivering inexpensive, accessible, fast, and convenient healthcare services.

Treatment of recurrent IVF failure and human leukocyte antigen similarity by intravenous immunoglobulin.

This study sought to assess the efficacy of intravenous immunoglobulin (IVIg) in improving pregnancy rates and outcome, in a select group of patients with repeated IVF failure and human leukocyte antigen (HLA) similarity. Couples suffering from recurrent IVF failure, defined as at least seven attempts at embryo transfer with no successful implantations, who were found to share at least three HLA loci, and a negative cross-match test, were included in the study. The treatment consisted of two 30 g IVIg doses: one before oocyte retrieval, and a second as soon as a fetal pulse was identified on ultrasound. Ten couples comprised the study group. In total, these couples had undergone 98 IVF cycles with no successful pregnancies prior to initiation of the study. Following a total of 18 IVIg courses, seven women conceived, two women twice. Up to date, five women have delivered at least one live fetus, at 27 weeks or later. One woman is currently in the early third trimester of a twin pregnancy, and one woman had a late abortion at 19 weeks. The results suggest that couples with recurrent IVF failure and HLA similarity, may benefit from IVIg treatment.

Monoamniotic twins: an update on antenatal diagnosis and treatment.

OBJECTIVE: Monoamniotic twins are very uncommon and are characterized by a high perinatal mortality rate. Cord entanglement, prematurity, congenital anomalies and twin to twin transfusion are reportedly the main causes of death, which usually occurs before 24 weeks' gestation. The aim of this study was to review the newly developed methods for diagnosis and treatment and suggest a reasonable approach to the management of these rare cases. METHOD: We reviewed the English-language literature in the past 15 years through Medline search and subsequent examination of individual publications. RESULTS: In the past two decades, newer technologies such as advanced ultrasonography and color flow Doppler studies have enabled early diagnosis of this condition and its complications. Furthermore, new treatment modalities such as fetoscopy with laser coagulation of vascular anastomoses and treatment with non-steroidal anti-inflammatory drugs such as sulindac, to reduce amniotic fluid volume, may have contributed to a better outcome. Also, occlusion of one umbilical cord (fetal reduction) at an early stage has been suggested to prevent late complications. CONCLUSION: Cumulative experience suggests that the majority of cases can be diagnosed reliably at an early gestational age. Treatment with medical amnioreduction, surgical amnioreduction or fetal reduction in selected cases may be offered before 24 weeks' gestation. Later, intensive antepartum fetal surveillance should probably be offered until 32 weeks, at which point elective preterm delivery may be considered to prevent possible fetal death.

Fetal hydrops, associated with maternal propylthiouracil exposure, reversed by intrauterine therapy.

Thyroid hormone is essential for fetal neurological development. Among other etiologies, fetal hypothyroidism may be caused by maternal exposure to antithyroid drugs (ATDs). The most common presentation of fetal hypothyroidism is fetal goiter, which can cause dystocia, in addition to airway obstruction in the neonate. Intra-amniotic treatment with levothyroxine normalizes fetal thyroid status and reduces goiter size. We present a case of fetal hypothyroidism diagnosed in a patient who was treated with propylthiouracil (PTU) for Grave's disease. The fetus had marked hydrops fetalis and a large goiter. In addition, anal stenosis, vesicovaginal fistula, bilateral pyelectasia and polydactyly were diagnosed in the neonate. Intra-amniotic treatment with levothyroxine resulted in a regression of the hydrops and a reduction in the goiter size. A euthyroid, non-edematous, non-goitrous neonate was delivered. At the age of 27 months the child's psychomotor development was normal. The present case indicates that hydrops fetalis may be an unusual manifestation of fetal hypothyroidism, caused by intrauterine exposure to maternal antithyroid drugs (ATDs), and that it may be resolved by treatment with intra-amniotic levothyroxine.
