Permanent or absorbable suture material for sacrospinous ligament fixation: Does it matter?

OBJECTIVE

To evaluate success and safety of sacrospinous ligament fixation (SSLF) using permanent versus absorbable suture materials 12 months following surgery.

STUDY DESIGN

Following IRB approval, the electronic medical records of women who underwent SSLF in the gynecology department of a university-affiliated medical center from November 2012 to September 2021 were retrospectively reviewed. SSLF was carried out using Capio®and Digitex™, with either absorbable (polyglactin-910 or polydioxanone) sutures (group 1), or permanent (polypropylene) sutures (group 2), Pre-operative and post-operative assessment included prolapse staging using the pelvic organ prolapse quantification system and validated quality of life questionnaires (Pelvic Floor Distress Inventory and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12). Patients with postoperative information on objective and subjective outcome at 12 months were included in final analysis. Anatomical success was defined as POP stage < 2 at 12-months following surgery. For statistical analysis, the Mann-Whitney test was used for continuous variables, Fisher's exact test for dichotomous variables, and Chi-squared test of independence for variables with>2 categories.

RESULTS

During the study period, 234 women underwent SSLF. One-hundred and forty-two patients (60.7 %) returned at the 12-month follow-up and were included in final analysis. Seventy-two (50.7 %) patients had absorbable suture and 70 patients (49.3 %) had permanent suture. Estimated blood loss was significantly higher in group 1 [100 (50-150) cc vs 50 (50-100) cc respectively, p =.016]. Moderate to severe pain on POD-1 was significantly higher in group 2 [VAS: 2.00 (0.00-4.00) vs 4.00 (3.00-5.75) respectively, p =.001]. Anatomical success, defined as POP ≤ stage 2 at 12 months, was similar between groups: 69 % in group 1 vs 67 % in group 2 (p =.77). Subjective cure was similar between groups, 97.2 % in group 1 vs 94.3 % in group 2 (p =.44). At the 12-month follow-up, none of the patients had gluteal pain. The rate of de-novo dyspareunia was similar between groups: 4 women (5.9 %) in the absorbable suture group versus 2 women (3.3 %) in the permanent suture group (p =.49).

CONCLUSIONS

Our findings suggest that absorbable or permanent suture material does not affect outcome of SSLF. Permanent sutures may be related to increased immediate postoperative pain.

Post-hemithyroidectomy Pregnancy Thyroid Function Surveillance - Frequency, Adherence and Guideline Impact

OBJECTIVE

Post-hemithyroidectomy women are at increased risk for gestational subclinical hypothyroidism. Therefore, the American Thyroid Association (ATA) recommends increased thyroid function surveillance for this subgroup of pregnant women. The Purpose of this study was to evaluate the frequency of thyroid function surveillance during pregnancy in post-hemithyroidectomy women, and to evaluate the adherence to the 2017 ATA guidelines and its possible impact since being published, on thyroid function surveillance rates.

METHODS

A retrospective study including all pregnancies conceived by post-hemithyroidectomy women operated at our institution between the years 1997-2020. The study cohort was subdivided by pregnancy date prior to 2018 and 2018 and onwards to evaluate the impact of the 2017 ATA guidelines. Adherence to the guidelines was defined as at least one TSH test in each trimester.

RESULTS

After exclusions, a total of 120 pregnancies conceived by 66 women who underwent hemithyroidectomy surgeries were included in this study. Overall, serum TSH examinations were performed during the first, second and third pregnancy trimesters in 86.6%, 40% and 16.6% of pregnancies (P<0.005), respectively. The examination rate since 2018 was 88%, 40% and 8% for first, second and third trimester, respectively (P<0.005).

CONCLUSION

Adherence to the latest ATA guidelines is low and its publication in 2017 did not increase the thyroid function surveillance rate in post-hemithyroidectomy women. Better patient education regarding the risks of gestational hypothyroidism following hemithyroidectomy and improved communications between treating surgeons, obstetricians, and endocrinologists may improve these rates.

Patterns of care and dropout rates from outpatient mental healthcare in low-, middle- and high-income countries from the World Health Organization's World Mental Health Survey Initiative

BACKGROUND

There is a substantial proportion of patients who drop out of treatment before they receive minimally adequate care. They tend to have worse health outcomes than those who complete treatment. Our main goal is to describe the frequency and determinants of dropout from treatment for mental disorders in low-, middle-, and high-income countries.

METHODS

Respondents from 13 low- or middle-income countries (N = 60 224) and 15 in high-income countries (N = 77 303) were screened for mental and substance use disorders. Cross-tabulations were used to examine the distribution of treatment and dropout rates for those who screened positive. The timing of dropout was examined using Kaplan-Meier curves. Predictors of dropout were examined with survival analysis using a logistic link function.

RESULTS

Dropout rates are high, both in high-income (30%) and low/middle-income (45%) countries. Dropout mostly occurs during the first two visits. It is higher in general medical rather than in specialist settings (nearly 60% v. 20% in lower income settings). It is also higher for mild and moderate than for severe presentations. The lack of financial protection for mental health services is associated with overall increased dropout from care.

CONCLUSIONS

Extending financial protection and coverage for mental disorders may reduce dropout. Efficiency can be improved by managing the milder clinical presentations at the entry point to the mental health system, providing adequate training, support and specialist supervision for non-specialists, and streamlining referral to psychiatrists for more severe cases.

Multiple Traumas, Maternal Depression, Mother-Child Relationship, Social Support, and Young Children's Behavioral Problems

This study examined whether maternal depression, mother-child relationships, and maternal perceived social support mediate the associations between child's exposure to multiple traumatic events and behavioral problems. We recruited a representative sample of 904 Israeli (Jewish and Arab) mothers and their 2- to 6-year-old children. Data collection was conducted through structured face-to-face interviews with the mothers between July and November 2011. All measures were completed by the mothers. We used the child's and mother's exposure to political violence questionnaires, Child Behavior Checklist (CBCL), a short version of the Parental Acceptance-Rejection Questionnaire (PARQ), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Medical Outcomes Study (MOS) Social Support Survey. The research study model was tested using path analysis. The model showed a very good fit to the data, suggesting that maternal rejection, maternal depression, and social support play an important role in child's behavioral problems in the context of multiple traumatic events. Higher levels of maternal rejection were significantly associated with greater children behavior problems. Maternal rejection mediated the associations between maternal depressive symptoms and child's behavioral problems. Maternal perceived social support mediated the associations between child's exposure to multiple traumatic events and child's behavioral problems; child's exposure to multiple traumatic events was associated with lower levels of maternal perceived social support. In turn, lower levels of perceived social support were associated with higher levels of behavioral problems. In conclusion, in accordance with the "social stress framework," social support has a mediation role in the association between exposure to traumatic events and child's behavioral problems. Thus, enhancing social support to mothers to young children in the context of multiple traumatic events is essential for children resiliency.

Perceived helpfulness of treatment for posttraumatic stress disorder: Findings from the World Mental Health Surveys

BACKGROUND

Perceived helpfulness of treatment is an important healthcare quality indicator in the era of patient-centered care. We examine probability and predictors of two key components of this indicator for posttraumatic stress disorder (PTSD).

METHODS

Data come from World Mental Health surveys in 16 countries. Respondents who ever sought PTSD treatment (n = 779) were asked if treatment was ever helpful and, if so, the number of professionals they had to see to obtain helpful treatment. Patients whose treatment was never helpful were asked how many professionals they saw. Parallel survival models were estimated for obtaining helpful treatment in a specific encounter and persisting in help-seeking after earlier unhelpful encounters.

RESULTS

Fifty seven percent of patients eventually received helpful treatment, but survival analysis suggests that it would have been 85.7% if all patients had persisted in help-seeking with up to six professionals after earlier unhelpful treatment. Survival analysis suggests that only 23.6% of patients would persist to that extent. Odds of ever receiving helpful treatment were positively associated with receiving treatment from a mental health professional, short delays in initiating help-seeking after onset, absence of prior comorbid anxiety disorders and childhood adversities, and initiating treatment before 2000. Some of these variables predicted helpfulness of specific treatment encounters and others predicted persistence after earlier unhelpful encounters.

CONCLUSIONS

The great majority of patients with PTSD would receive treatment they considered helpful if they persisted in help-seeking after initial unhelpful encounters, but most patients whose initial treatment is unhelpful give up before receiving helpful treatment.

Findings From World Mental Health Surveys of the Perceived Helpfulness of Treatment for Patients With Major Depressive Disorder

IMPORTANCE

The perceived helpfulness of treatment is an important patient-centered measure that is a joint function of whether treatment professionals are perceived as helpful and whether patients persist in help-seeking after previous unhelpful treatments.

OBJECTIVE

To examine the prevalence and factors associated with the 2 main components of perceived helpfulness of treatment in a representative sample of individuals with a lifetime history of DSM-IV major depressive disorder (MDD).

DESIGN, SETTING, AND PARTICIPANTS

This study examined the results of a coordinated series of community epidemiologic surveys of noninstitutionalized adults using the World Health Organization World Mental Health surveys. Seventeen surveys were conducted in 16 countries (8 surveys in high-income countries and 9 in low- and middle-income countries). The dates of data collection ranged from 2002 to 2003 (Lebanon) to 2016 to 2017 (Bulgaria). Participants included those with a lifetime history of treated MDD. Data analyses were conducted from April 2019 to January 2020. Data on socioeconomic characteristics, lifetime comorbid conditions (eg, anxiety and substance use disorders), treatment type, treatment timing, and country income level were collected.

MAIN OUTCOMES AND MEASURES

Conditional probabilities of helpful treatment after seeing between 1 and 5 professionals; persistence in help-seeking after between 1 and 4 unhelpful treatments; and ever obtaining helpful treatment regardless of number of professionals seen.

RESULTS

Survey response rates ranged from 50.4% (Poland) to 97.2% (Medellín, Columbia), with a pooled response rate of 68.3% (n = 117 616) across surveys. Mean (SE) age at first depression treatment was 34.8 (0.3) years, and 69.4% were female. Of 2726 people with a lifetime history of treatment of MDD, the cumulative probability (SE) of all respondents pooled across countries of helpful treatment after seeing up to 10 professionals was 93.9% (1.2%), but only 21.5% (3.2%) of patients persisted that long (ie, beyond 9 unhelpful treatments), resulting in 68.2% (1.1%) of patients ever receiving treatment that they perceived as helpful. The probability of perceiving treatment as helpful increased in association with 4 factors: older age at initiating treatment (adjusted odds ratio [AOR], 1.02; 95% CI, 1.01-1.03), higher educational level (low: AOR, 0.48; 95% CI, 0.33-0.70; low-average: AOR, 0.62; 95% CI, 0.44-0.89; high average: AOR, 0.67; 95% CI, 0.49-0.91 vs high educational level), shorter delay in initiating treatment after first onset (AOR, 0.98; 95% CI, 0.97-0.99), and medication received from a mental health specialist (AOR, 2.91; 95% CI, 2.04-4.15). Decomposition analysis showed that the first 2 of these 4 factors were associated with only the conditional probability of an individual treatment professional being perceived as helpful (age at first depression treatment: AOR, 1.02; 95% CI, 1.01-1.02; educational level: low: AOR, 0.48; 95% CI, 0.33-0.70; low-average: AOR, 0.62; 95% CI, 0.44-0.89; high-average: AOR, 0.67; 95% CI, 0.49-0.91 vs high educational level), whereas the latter 2 factors were associated with only persistence (treatment delay: AOR, 0.98; 95% CI, 0.97-0.99; treatment type: AOR, 3.43; 95% CI, 2.51-4.70).

CONCLUSIONS AND RELEVANCE

The probability that patients with MDD obtain treatment that they consider helpful might increase, perhaps markedly, if they persisted in help-seeking after unhelpful treatments with up to 9 prior professionals.

The epidemiology of alcohol use disorders cross-nationally: Findings from the World Mental Health Surveys

BACKGROUND

Prevalences of Alcohol Use Disorders (AUDs) and Mental Health Disorders (MHDs) in many individual countries have been reported but there are few cross-national studies. The WHO World Mental Health (WMH) Survey Initiative standardizes methodological factors facilitating comparison of the prevalences and associated factors of AUDs in a large number of countries to identify differences and commonalities.

METHODS

Lifetime and 12-month prevalence estimates of DSM-IV AUDs, MHDs, and associations were assessed in the 29 WMH surveys using the WHO CIDI 3.0.

RESULTS

Prevalence estimates of alcohol use and AUD across countries and WHO regions varied widely. Mean lifetime prevalence of alcohol use in all countries combined was 80%, ranging from 3.8% to 97.1%. Combined average population lifetime and 12-month prevalence of AUDs were 8.6% and 2.2% respectively and 10.7% and 4.4% among non-abstainers. Of individuals with a lifetime AUD, 43.9% had at least one lifetime MHD and 17.9% of respondents with a lifetime MHD had a lifetime AUD. For most comorbidity combinations, the MHD preceded the onset of the AUD. AUD prevalence was much higher for men than women. 15% of all lifetime AUD cases developed before age 18. Higher household income and being older at time of interview, married, and more educated, were associated with a lower risk for lifetime AUD and AUD persistence.

CONCLUSIONS

Prevalence of alcohol use and AUD is high overall, with large variation worldwide. The WMH surveys corroborate the wide geographic consistency of a number of well-documented clinical and epidemiological findings and patterns.

Somatic Experiencing for Posttraumatic Stress Disorder: A Randomized Controlled Outcome Study

This study presents the first known randomized controlled study evaluating the effectiveness of somatic experiencing (SE), an integrative body-focused therapy for treating people with posttraumatic stress disorder (PTSD). There were 63 participants meeting DSM-IV-TR full criteria for PTSD included. Baseline clinical interviews and self-report measures were completed by all participants, who were then randomly assigned to study (n = 33) or waitlist (n = 30) groups. Study participants began 15 weekly SE sessions, whereas waitlist participants waited the same period, after which the second evaluation was conducted. All participants were evaluated a third time after an additional 15 weeks, during which time the waitlist group received SE therapy. Pretreatment evaluation showed no significant differences between groups. Mixed model linear regression analysis showed significant intervention effects for posttraumatic symptoms severity (Cohen's d = 0.94 to 1.26) and depression (Cohen's d = 0.7 to 1.08) both pre-post and pre-follow-up. This randomized controlled study of SE shows positive results indicating SE may be an effective therapy method for PTSD. Further research is needed to understand who shall benefit most from this treatment modality.

Teaching mandibular implant-Supported overdentures in dental schools in North America - a survey

INTRODUCTION

Mandibular two-implant overdentures are considered the minimum standard of care for edentulous patients and provide an excellent performance, as well as satisfaction to the patients. Dental schools are required to promote the teaching of current treatment options in order to enable students to master state-of-the-art procedures.

AIMS

The purpose of this study was to examine how the theoretical and practical aspects of mandibular two-implant overdentures are taught in dental schools in North America.

METHODS

Data were collected via an online questionnaire that included questions regarding the theoretical and clinical courses, surgical procedure and imaging method.

RESULTS

Of 75 schools, 36 responded to the survey. Almost all the schools teach the subject theoretically, but it is not mandatory for students to perform in most of the schools. Only a minority (23%) of the mandibular dentures made by students are implant-supported. Almost all of the schools (94%) use two implants to support overdentures, and Locator abutment is used almost exclusively. The prevalent imaging for the surgical procedure is CT scans, although 30% of the schools use panoramic radiograph. None of the schools loads the implants immediately after surgery.

CONCLUSION

Some clear trends are apparent in the current survey: the use of two implants, no use of bar connectors and delayed loading of the implants. It is likely that graduates will not have sufficient clinical skills and will need continuing education to be familiar with the required procedures, both surgical and prosthetic.

Stability and Change in Posttraumatic Distress: A 7-Year Follow-Up Study of Mothers and Young Children Exposed to Cumulative Trauma

In situations of cumulative trauma, it is often unclear why some people remain resilient, whereas others experience distress, and how likely these responses are to change over time. To investigate the constancy of responses to cumulative trauma, stability and change in posttraumatic distress and resistance (as defined by no evidence of clinical symptoms) were assessed twice in 140 Israeli children and mothers exposed to continual rocket attacks over approximately 7 years, when the children were 2-4 (Time 1) and 9-11 years of age (Time 2). Measures included trauma exposure, posttraumatic and depressive symptoms, and child behavioral problems. We identified 4 longitudinal courses (LCs): resilient (resistance at Time 1 and Time 2), recovered (clinical distress at Time 1 and resistance at Time 2), developed symptoms (resistance at Time 1 and clinical distress at Time 2), and chronic distress (clinical distress at Time 1 and Time 2). Results showed more stability than change in the frequencies of resistance at both times of measurement. The resilient LC was the most common longitudinal course for both mothers and children. Multinomial regression models indicated that maternal posttraumatic symptoms predicted the recovered and chronic distress LCs of the children.

Detection and characterization of carbapenemase-producing Enterobacteriaceae in wounded Syrian patients admitted to hospitals in northern Israel

Since 2013, four hospitals in northern Israel have been providing care for Syrian nationals, primarily those wounded in the ongoing civil war. We analyzed carbapenemase-producing Enterobacteriaceae (CPE) isolates obtained from these patients. Isolate identification was performed using the VITEK 2 system. Polymerase chain reaction (PCR) was performed for the presence of bla KPC, bla NDM, and bla OXA-48. Susceptibility testing and genotyping were performed on selected isolates. During the study period, 595 Syrian patients were hospitalized, most of them young men. Thirty-two confirmed CPE isolates were grown from cultures taken from 30 patients. All but five isolates were identified as Klebsiella pneumoniae and Escherichia coli. Nineteen isolates produced NDM and 13 produced OXA-48. Among a further 29 isolates tested, multilocus sequence typing (MLST) showed that ST278 and ST38 were the major sequence types among the NDM-producing K. pneumoniae and OXA-48-producing E. coli isolates, respectively. Most were resistant to all three carbapenems in use in Israel and to gentamicin, but susceptible to colistin and fosfomycin. The source for bacterial acquisition could not be determined; however, some patients admitted to different medical centers were found to carry the same sequence type. CPE containing bla NDM and bla OXA-48 were prevalent among Syrian wounded hospitalized patients in northern Israel. The finding of the same sequence type among patients at different medical centers implies a common, prehospital source for these patients. These findings have implications for public health throughout the region.

The Effectiveness of Group Intervention on Enhancing Cognitive Emotion Regulation Strategies in Breast Cancer Patients: A 2-Year Follow-up

Purpose To evaluate the long-term effect of group intervention on enhancing cognitive emotion regulation (CER) strategies in female patients with early-stage breast cancer. Methods The sample included 174 patients who were diagnosed with early-to-mid stage breast cancer, completed adjuvant therapy, and agreed to fill out demographic and cognitive emotion regulation questionnaires (CERQ). About half of the patients (86, 49.4%) chose to participate in an 8-session group intervention (intervention group) while the others (88, 50.6%) did not (comparison group). The structured intervention for enhancing coping strategies with special emphasis on emotion regulation was conducted at the oncology unit at Rabin Medical Center by 2 experienced therapists. Preliminary effects on CER evaluated 6, 12, and 24 months postintervention were compared to the CER of a group of patients that opted not to participate in the group intervention. Results In the intervention group, the long-term effect (from baseline to 24 months) was assessed using the mix models module. Significant interaction effects were found for both the Negative CER scales (F(3, 268  ,404) = 3.66, P = .01) and for the Positive CER scales (F(3, 271  ,660) = 5.12, P = .002). No statistically significant differences in socio-demographic characteristics and medical variables were observed between the intervention and comparison groups. Conclusion Our findings indicate that a group intervention aimed at empowerment of coping strategies had positive long-term outcomes that reinforce adaptive coping strategies and improve less effective strategies of cognitive emotion regulation.

Posttraumatic Growth in Breast Cancer Survivors: Constructive and Illusory Aspects

This study investigated the impact of a building-resilience intervention on coping and posttraumatic growth (PTG) in a convenience sample of 94 breast cancer survivors. PTG was divided into constructive and illusory components, based on the two-sided Janus face model (Maercker & Zoellner, 2004). We operationalized constructive PTG as an improvement in both PTG and coping, and illusory PTG as an improvement in PTG only. An 8-session group intervention was delivered to 49 women (mean age = 51.5 years, SD = 10.7) who completed self-report questionnaires at baseline and at 6 months follow-up; a control group of 45 women only completed questionnaires. More than half the participants (n = 53; 56.38%) reported increased PTG at 6 months (mean change = 0.56, SD = 0.48, η(2) = .58). The increase in both PTG and positive coping was significantly greater in the intervention group than the control group (B = 0.23 for PTG, and B = 0.35 for positive coping). Further, a higher proportion of constructive PTG (vs. illusory PTG) was reported by the participants in the intervention group (89.3%), as compared to the control group (56.3%; z = 2.57). The distinction between constructive and illusory PTG has clinical implications for interventions promoting coping and growth among cancer survivors.

A novel anchoring system for colonic stents: a pilot in vivo study in a porcine model

BACKGROUND

Colorectal stents have a proven role in colorectal cancer as palliative care or a bridge to surgery. However, their efficacy and anchoring to the tissue varies according to stent design with stent migration rates up to 50 %. We present preliminary in vivo results of a new end-luminal anchoring system for stent fixation to the rectal canal. The aim was to assess the efficacy and safety of the stent using the anchoring system while subjecting the device to daily abdominal pressures related to daily activities in a porcine animal model.

METHODS

Ex vivo anatomical and physical studies were performed to improve the system's structure and safety. Four female pigs were followed for the acute and chronic (16 weeks) period. Two animals were euthanized and underwent en-bloc pelvic visceral excision and histopathological examination. Device fixation time, animal behavior, device patency, anoscopic examination and histopathological features were assessed.

RESULTS

Mean anchoring time was 13.83 weeks (standard error ± 1.38 weeks). One of the animals experienced early device expulsion with no complications. No obstruction was noted in any of the animals. Macroscopic examination revealed mild focal submucosal scarring in one animal and a normal examination in the other. Hematoxylin and eosin staining revealed mucosal ulceration and mixed inflammatory cell infiltrate, with no signs of granulomata, foreign body giant cell reaction or microabscess formation.

CONCLUSIONS

A novel fixation device designed for long-term intrarectal implantation was well tolerated and maintained anal canal patency without migration. Larger studies are needed before its implementation in humans.

Post anterior rectal resection syndrome--a retrospective multicentre study

AIM

The long-term effects of surgical and non-surgical factors on increased stool frequency and incontinence following anterior resection have been variably reported. We investigated the effects of surgical characteristics on symptoms at 1 month and more than 1 year postoperatively following anterior resection of the rectum.

METHOD

In this retrospective study of patients who underwent anterior resection of the rectum during 2002-2006, patients were interviewed regarding symptoms at 1 month and more than 1 year postoperatively. Anterior resection of the rectum syndrome (ARRS) is more simply defined as incontinence and/or frequent bowel movements after surgery and graded as severe, moderate or mild.

RESULTS

Of the 165 patients who underwent anterior resection for rectal cancer during the study period, 106 were included in the analysis. The median follow-up period was 3.4 years (range 13-72 months). ARRS had a high prevalence 1 month postoperatively (55.6%) but abated in over half the cases at 1 year postoperatively. The likelihood of development of early but not late ARRS was associated with the anastomotic level suggesting adaptation. ARRS and continence were unaffected by total mesorectal excision, the use of adjuvant radiation or chemotherapy, patient age or disease stage.

CONCLUSION

The level of anastomosis in anterior resection of the rectum had a significant effect on the prevalence of ARRS using a new simpler definition 1 month after surgery but not 1 year or more postoperatively. Further data on neorectal reservoir reconstruction using the simpler ARRS definition are required.

Low anterior resection syndrome (LARS): cause and effect and reconstructive considerations

Between 25 and 80% of patients undergoing a low or very low anterior resection will suffer postoperatively, from a constellation of symptoms including fecal urgency, frequent bowel movements, bowel fragmentation and incontinence, collectively referred to as the low anterior resection syndrome (LARS). The etiology of LARS is multifactorial with the potential of sphincter injury during anastomosis construction, alterations in anorectal physiology, the development of a pudendal neuropathy, and a lumbar plexopathy with exacerbation of symptoms if there is associated anastomotic sepsis or the use of adjuvant and neoadjuavnt therapies. The symptoms of LARS may be obviated in part by the construction of a neorectal reservoir which may take the form of a colonic J-pouch, a transverse coloplasty, or a side-to-end anastomosis. This review outlines the factors contributing to LARS symptomatology along with the short- and medium-term functional results of comparative trials with the different types of neorectal reconstructions.

Colorectal carcinoma in inflammatory bowel disease: a comparison between Crohn's and ulcerative colitis

AIM

The study assessed the clinicopathological features and survival rates of inflammatory bowel disease (IBD) patients with colorectal carcinoma (CRC), which accounts for ∼ 15% of all IBD associated death.

METHOD

The medical records of patients operated on for CRC in three institutions between 1992 and 2009 were reviewed, and those with Crohn's colitis (CC) and ulcerative colitis (UC) were identified. Data on age, gender, disease duration, colitis severity, surgical procedure, tumour stage and survival were retrieved.

RESULTS

Fifty-three patients (40 UC and 13 CC, 27 men, mean age at operation 54 years) were found. All parameters were comparable between the groups. Mean disease duration before CRC was 22.7 years for UC and 16.6 years for CC patients (P = 0.04). CRC was diagnosed preoperatively in 43 (81%) patients. Twenty-eight patients had colon cancer, 23 had rectal cancer and two patients had more than one cancer. All malignancies were located in segments with colitis. Over one-half were diagnosed at an advanced stage (36% stage III; 17% stage IV). At a mean follow up of 56 ± 65 months, 60% were alive (54% disease free) and 40% were dead from cancer-related causes. The 5-year survival rate was 61% for the UC and 37% for the CC patients (P = NS).

CONCLUSION

CRC in IBD patients is frequently diagnosed at an advanced stage, a factor that contributes to poor prognosis. The risk of CRC in CC patients is comparable to those with UC. Long-term surveillance is recommended for patients with long-standing CC and UC.

The effect of neoadjuvant Imatinib therapy on outcome and survival after rectal gastrointestinal stromal tumour

AIM

The study aimed to characterize the pathological and clinical response of rectal gastrointestinal stromal tumours (GISTs) to neoadjuvant Imatinib.

METHOD

The medical records of patients with rectal GISTs who were diagnosed and treated in five medical centres in Israel between January 2002 and January 2009 were retrospectively examined. Twelve patients who fulfilled the inclusion criteria of nonmetastatic rectal GIST for which preoperative neoadjuvant treatment with Imatinib was considered were suitable for enrollment.

RESULTS

Of the 12 patients, nine received neoadjuvant treatment with Imatinib. The three patients who had immediate surgery were excluded. There were five men and four women with a median age of 63 years and a median follow up of 32 months. All tumours were located in the lower two-thirds of the rectum. One patient had a complete clinical response, six had a partial response and two had stable disease. Seven patients subsequently underwent surgery; six had an R0 resection and one had an R1 resection. Three patients had recurrence. There was no disease-related mortality. The reduction in both tumour size and mitotic activity during preoperative Imatinib therapy was significant.

CONCLUSION

Preoperative Imatinib therapy can shrink large rectal GISTs, improving the chances of successful radical surgery and decreasing the risk of considerable morbidity.

Long-term outcome of loose seton for complex anal fistula: a two-centre study of patients with and without Crohn's disease

OBJECTIVE

Complex anal fistulas traverse a significant portion of the external sphincter muscle, making their treatment a surgical challenge. Several surgical options are used with conflicting results. The aim of this study was to analyse the results of permanent loose seton in the management of high anal fistulas in Crohn's disease (CD) patients and two-stage seton fistulotomy in patients without CD.

METHOD

We retrospectively reviewed the clinical records of 77 patients with complex anal fistula treated by loose seton over a 4-year period, in two medical centres. Recorded parameters included demographics, medical history, type of fistula, disease duration, previous surgery, morbidity, recurrence and mortality.

RESULTS

Sixty patients without CD underwent 107 fistula-related surgical procedures, and 17 CD patients underwent 29 procedures. Early postoperative complications were recorded in eight (10%) patients. Perioperative complications, mainly local sepsis or bleeding, were recorded in eight (10%) patients. Long-term complications were observed in nine non-CD and four CD patients. During a median follow-up period of 24 months, the recurrence rate was 40% in CD patients and 47% in patients without CD. Five patients (four non-CD patients and one CD patient) developed some degree of faecal incontinence.

CONCLUSION

The fistula recurrence rate following two-stage seton fistulotomy in non-CD patients was high. In CD patients the use of permanent loose seton is effective in controlling local sepsis in about half of patients and has low rates of subsequent incontinence.
