RESUMO
OBJECTIVE: Spontaneous spinal cerebrospinal fluid (CSF) leaks cause intracranial hypotension (SIH) and also may cause infratentorial superficial siderosis (iSS) but the rate of development among different CSF leak types and outcome of treatment are not known. We determined the time interval from SIH onset to iSS and the outcome of treatment. METHODS: A total of 1,589 patients with SIH underwent neuroimaging and iSS was detected in 57 (23 men and 34 women, mean age = 41.3 years [3.6%]). We examined the type of underlying CSF leak by various imaging modalities. Percutaneous and surgical procedures were used to treat the CSF leaks. RESULTS: The iSS was detected in 46 (10.3%) of 447 patients with ventral CSF leaks, in 2 (3.9%) of 51 patients with dural ectasia, in 5 (2.6%) of 194 patients with CSF-venous fistulas, in 4 (0.9%) of 457 patients with simple meningeal diverticula, and in none of the 101 patients with lateral CSF leaks or the 339 patients with leaks of indeterminate origin (p < 0.001). The estimated median latency period from SIH onset to iSS was 126 months. Ventral CSF leaks could not be eliminated with percutaneous procedures in any patient and surgical repair was associated with low risk (<5%) and resulted in resolution of the CSF leak in all patients in whom the exact site of the CSF leak could be determined. Other types of CSF leak were treated with percutaneous or surgical procedures. INTERPRETATION: The iSS can develop in most types of spinal CSF leak, including CSF-venous fistulas, but mainly in chronic ventral CSF leaks, which require surgical repair. ANN NEUROL 2023;93:64-75.

OBJECTIVE: Choosing the right hemodialysis vascular access for frail patients remains difficult because the patient's preferences and the likelihood of access function and survival must be considered. We hypothesize that patients identified before arteriovenous (AV) access as frail by the PRISMA-7 score may have worse outcomes, indicating that fistula creation may not be the most clinically beneficial option and it would be in the best interest of the patient to receive either AV graft (AVG) placement or dialysis through a percutaneous catheter. Our pilot study aims to determine whether an association exists between patient frailty as defined by PRISMA-7 and newly created AV fistula (AVF) and AVG access outcomes. METHODS: This was a single institutional prospective cohort study of patients undergoing new AVF or AVG intervention from April 2021 to May 2023. Patients were assessed using the PRISMA-7 frailty questionnaire before their AV access surgery. Patients were grouped by frailty score and score groups were examined for trends. Univariable analysis was performed for baseline differences between frail and nonfrail patients. Failure to achieve maturation, postoperative infection, and 180-day mortality difference was also investigated for frail vs nonfrail patients. Univariable analysis was performed for nonmaturation using standard comorbidities, arterial and venous diameters, and frailty. Multivariable binary logistic regression was performed for the outcome of nonmaturation using frailty as one of the variables in conjunction with the univariable risks associated with nonmaturation. RESULTS: A total of 40 patients undergoing new AV access placement were investigated, among whom 53% were designated as frail (PRISMA-7 score ≥3). When comparing the frail and nonfrail new AV access groups, the access (AVF and AVG combined) failed in 48% (10/21) of the frail patients, but only failed in 5% (1/19) of the nonfrail patients 1 (P = .012). When distinguishing between AV access types, AVF creations followed the overall trend with 60% of AVF access (9/15) sites in frail patients failing to mature when compared with nonfrail patients, who all had fistulas that matured to use (P = .049). Surgical site infection was absent in all frail patients and present in 5% of nonfrail patients (1/19). Both 30-day and 60-day readmission rates were higher in the frail group compared with the nonfrail group. There was 180-day mortality present in 5 of frail patients % (1/21) and absent in nonfrail patients. Multivariable analysis revealed that both frailty (adjusted odd ratio, 10.19; 95% confidence interval, 1.20-82.25); P = .033) and younger age (adjusted odd ratio, 0.953; 95% confidence interval, 0.923-0.983; P = .002) both had a significant association with nonmaturation. Power analysis revealed a power statistic of 0.898 indicating a probability of type 2 error of 10.02% with a P value of .002. Hosmer-Lemeshow goodness of fit for the logistic regression had 75% overall accuracy for the model. CONCLUSIONS: Patient frailty is significantly associated with an increased incidence of AV access failure to mature.

OBJECTIVE: Groin wound complications are common following vascular surgery and can lead to significant patient morbidity. Sartorius muscle flap coverage may help to prevent vascular graft infection in the setting of wound dehiscence or infection. However, risk factors and consequences of wound complications following sartorius flap reconstruction remain incompletely investigated. METHODS: We retrospectively queried all patients who underwent sartorius flap reconstruction at a tertiary academic medical center. Data collected included patient demographics, medical comorbidities, surgical indication, index vascular procedure, and postoperative outcomes. The primary outcome was wound complication following sartorius flap procedure, which was defined as groin wound infection, dehiscence, or lymphocutaneous fistula. RESULTS: From 2012 to 2022, a total of 113 patients underwent sartorius flap reconstruction. Of these, 66 (58.4%) were performed after the development of a prior groin complication, and 47 (41.6%) were prophylactic. A total of 88 patients (77.9%) had a prosthetic bypass graft adjacent to the flap. Twenty-nine patients (25.7%) suffered a wound complication following sartorius flap reconstruction, including 14 (12.4%) with wound dehiscence, 13 (11.5%) with wound infection, and two (1.8%) with lymphocutaneous fistula. Patients with wound complications had a higher body mass index (28.8 vs 26.4 kg/m2; P =.03) and more frequently active smokers (86.2% vs 66.7%; P = .04). Additionally, patients with wound complications had a higher unplanned 30-day hospital readmission rates (72.4% vs 15.5%; P < .001), reintervention rates (75.9% vs 8.3%; P < .001), and re-do flap reconstruction rates (13.8% vs 2.4%; P = .02). On multivariable analysis, higher body mass index was independently associated with post-flap wound complications (adjusted odds ratio [aOR], 1.01; 95% confidence interval [CI], 1.001-1.03; P = .037). Consequently, wound complications were associated with both surgical reintervention (aOR, 35.4; 95% CI, 9.9-126.3; P < .001) and unplanned hospital readmission (aOR, 17.8; 95% CI, 5.9-54.1; P < .001). CONCLUSIONS: Sartorius flap reconstruction is an effective adjunct in facilitating wound healing of groin wounds. However, wound complications are common following sartorius flap reconstruction and may be associated with reintervention and unplanned hospital readmission. These data support the judicious and thoughtful utilization of sartorius flap procedures among high-risk patients.

BACKGROUND: Patients undergoing arteriovenous (AV) access creation for hemodialysis often have significant comorbidities. Our goal was to quantify the long-term survival and associated risks factors for long-term mortality in these patients to aid in optimization of goals and expectations. METHODS: The Vascular Implant Surveillance and Interventional Outcomes Network Vascular Quality Initiative Medicare linked data was used to assess long-term survival in the HD registry. Demographics, comorbidities, and interventions were recorded. Because the majority of hemodialysis patients are provided Medicare, Medicare linkage was used to obtain survival data. Multivariable analysis was used to identify independent associations with mortality. RESULTS: There were 13,945 AV access patients analyzed including 10,872 (78%) AV fistulas and 3073 (22%) AV grafts. The median age was 67 years and 56% of patients were male. Approximately one-third had a prior AV access and 44.7% had prior tunneled dialysis catheters. Patients receiving an AV fistula, compared with AV grafts, were more often younger, male, White, obese, independently ambulatory, preoperatively living at home, and less often have a prior AV access and tunneled dialysis catheters (P < .05 for all). The 5-year mortality overall was 62.9% with 61.2% for AV fistulas and 68.8% for AV grafts (P < .001). On multivariable analysis for 5 year mortality, nonambulatory status (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.53-1.83; P < .001), lower extremity access (HR, 1.67; 95% CI, 1.35-2.05; P < .001), human immunodeficiency virus or acquired immunodeficiency syndrome (HR, 1.44; 95% CI, 1.13-1.82; P < .001), White race (HR, 1.43; 95% CI, 1.35-1.51; P < .001), congestive heart failure (HR, 1.33; 95% CI, 1.26-1.41; P < .001), chronic obstructive pulmonary disease (HR, 1.23; 95% CI, 1.15-1.31; P < .001), and AV graft placement (HR, 1.12; 95% CI, 1.02-1.23, P = .016) were most associated with poor survival. Factors associated with improved survival were never smoking (HR, .73; 95% CI, 0.67-0.79; P < .001), prior/quit smoking (HR, .78; 95% CI, 0.72-0.84; P < .001), preoperative home living (HR, .75; 95% CI, 0.68-0.83; P < .001), and hypertension (HR, .89; 95% CI, 0.8-0.99; P = .03). CONCLUSIONS: Long-term survival in Medicare patients undergoing AV access creation is poor with nearly two-thirds of patients having died at 5 years. There are many modifiable risk factors that may improve survival in these patients and give an opportunity for transplantation.

BACKGROUND: Heart disease and chronic kidney disease are often comorbid conditions owing to shared risk factors, including diabetes and hypertension. However, the effect of congestive heart failure (CHF) on arteriovenous fistula (AVF) and AV graft (AVG) patency rates is poorly understood. We hypothesize preexisting HF may diminish blood flow to the developing AVF and worsen patency. METHODS: We conducted a single-institution retrospective review of 412 patients with end-stage renal disease who underwent hemodialysis access creation from 2015 to 2021. Patients were stratified based on presence of preexisting CHF, defined as clinical symptoms plus evidence of reduced left ventricular ejection fraction (EF) (<50%) or diastolic dysfunction on preoperative echocardiography. Baseline demographics, preoperative measures of cardiac function, and dialysis access-related surgical history were collected. Kaplan-Meier time-to-event analyses were performed for primary patency, primary-assisted patency, and secondary patency using standard definitions for patency from the literature. We assessed differences in patency for patients with CHF vs patients without CHF, patients with a reduced vs a normal EF, and AVG vs AVF in patients with CHF. RESULTS: We included 204 patients (50%) with preexisting CHF with confirmatory echocardiography. Patients with CHF were more likely to be male and have comorbidities including, diabetes, chronic obstructive pulmonary disease, hypertension, and a history of cerebrovascular accident. The groups were not significantly different in terms of prior fistula history (P = .99), body mass index (P = .74), or type of hemodialysis access created (P = .54). There was no statistically significant difference in primary patency, primary-assisted patency, or secondary patency over time in the CHF vs non-CHF group (log-rank P > .05 for all three patency measures). When stratified by preoperative left ventricular EF, patients with an EF of <50% had lower primary (38% vs 51% at 1 year), primary-assisted (76% vs 82% at 1 year), and secondary patency (86% vs 93% at 1 year) rates than those with a normal EF. Difference reached significance for secondary patency only (log-rank P = .029). AVG patency was compared against AVF patency within the CHF subgroup, with significantly lower primary-assisted (39% vs 87% at 1 year) and secondary (62% vs 95%) patency rates for AVG (P < .0001 for both). CONCLUSIONS: In this 7-year experience of hemodialysis access creation, reduced EF is associated with lower secondary patency. Preoperative CHF (including HF with reduced EF and HF with preserved EF together) is not associated with significant differences in overall hemodialysis access patency rates over time, but patients with CHF who receive AVG have markedly worse patency than those who receive AVF. For patients with end-stage renal disease and CHF, the risks and benefits must be carefully weighed, particularly for those with low EF or lack of a suitable vein for fistula creation.

BACKGROUND: The treatment for lung oligometastasis from colorectal cancer (CRC) remains challenging. This retrospective study aimed to compare the local tumor control, survival and procedure-related complications in CRC patients undergoing low-dose rate stereotactic ablative brachytherapy (L-SABT) versus percutaneous microwave ablation (MWA) for lung oligometastasis. METHODS: Patients between November 2017 and December 2020 were retrospectively analyzed. Local tumor progression-free survival (LTPFS) and overall survival (OS) were analyzed in the entire cohort as well as by stratified analysis based on the minimal ablation margin (MAM) around the tumor. RESULTS: The final analysis included 122 patients: 74 and 48 in the brachytherapy and MWA groups, respectively, with a median follow-up of 30.5 and 35.3 months. The 1- and 3-year LTPFS rate was 54.1% and 40.5% in the brachytherapy group versus 58.3% and 41.7% in the MWA group (P = 0.524 and 0.889, respectively). The 1- and 3-year OS rate was 75.7% and 48.6% versus 75.0% and 50.0% (P = 0.775 and 0.918, respectively). Neither LTPFS nor OS differed significantly between the patients with MAM of 5-10 mm versus > 10 mm. Pulmonary complication rate did not differ in the overall analysis, but was significantly higher in the MWA group in the subgroup analysis that only included patients with lesion within 10 mm from the key structures (P = 0.005). The increased complications was primarily bronchopleural fistula. CONCLUSIONS: Considering the caveats associated with radioisotope use in L-SABT, MWA is generally preferable. In patients with lesion within 10 mm from the key pulmonary structures, however, L-SABT could be considered as an alternative due to lower risk of bronchopleural fistula.

OBJECTIVES: The reproductive desire of women following genital fistula repair surgery is complex, varied and often not addressed, although it carries significant consequences. The aim of this study was to better understand the fertility desires and sexual behaviours of women who recently underwent surgical repair of a genital fistula. METHODS: This is a secondary analysis of a retrospective cohort study designed to assess the effectiveness of Beyond Fistula, a reintegration programme for women recovering from genital fistula surgery in Eldoret, Kenya. One hundred women who participated in the Beyond Fistula programme between 2013 and 2019 were interviewed in person regarding future fertility desire, current sexual behaviour and contraceptive use. RESULTS: Among the 79 reproductive-aged women included in this study, 63.3% reported no future desire for pregnancy. Those that desired another pregnancy were significantly younger (48.3% were 18-29 years old vs. 66.0% were 35 years old or more, p = 0.004), had fewer living children (70% had 0-2 children vs. 56% had 3 or more children, p < 0.001), and a lower level of food insecurity (27.6% reported no to marginal insecurity vs. 14%, p = 0.014). Current sexual activity was marginally different between women who did and did not desire future pregnancy (82.8% vs. 66.0%, p = 0.053). Of the 50 women in our study who did not desire pregnancy, 62.0% were sexually active and of these, only 38.7% were preventing pregnancy. Lack of knowledge and access to methods were most commonly cited as barriers to use. CONCLUSIONS: Many women recovering from genital fistula surgery do not desire pregnancy and are sexually active but are not using a method to prevent pregnancy. The potential for post-surgical reintegration programmes to address education and access to contraception is a vital and unmet need to promote reproductive empowerment in this population of women as they reestablish their lives.

OBJECTIVE: Our aim is to describe the epidemiological, anatomoclinical and therapeutic profile of obstetric fistula (OF) in the Democratic Republic of the Congo (DRC). METHODOLOGY: This was a descriptive retrospective study that collected 1416 obstetric fistulas in 1267 patients in seven provinces of the DRC, treated between January 2017 and December 2022. The variables studied were epidemiological, anatomoclinical and therapeutic. RESULTS: The mean age of patients at the time of surgical repair was 33.2 years (range: 15 and 77 years) and 32.8% of patients were aged between 20 and 29 years. The mean age of the fistula at repair was 10 years (range: 3.5 months and 56 years). At the time of fistula, 61.7% of patients had delivered vaginally and 28.7% by caesarean section and 8.2% of patients had a haemostasis hysterectomy. Labour lasted at least 3 days in 47.3% of these patients for the fistula birth. Deliveries took place either at home (27.4%) or in a health facility (72.6%); 83.6% of newborns resulting from these births had died. Taken as a whole, urogenital fistulas are more common than genito-digestive fistulas. Urethro-vaginal (26.2%) and vesico-uterine (24.7%) anatomoclinical entities were predominant among urogenital fistulas. A total of 1416 fistulas were surgically repaired in 1267 patients. These repairs were successful for 1226 (86.6%) fistulas. The main surgical route used was transvaginal (68.8%). CONCLUSION: In the DRC, obstetric fistula is common in young adult women. It often results from vaginal delivery, after prolonged labour. Fistula births often result in the death of newborns. Uro-genital obstetric fistulas are the most frequent with predominance of urethro-vaginal and vesico-uterine anatomoclinical entities. Fistulas remain untreated for a long time. Mostly done transvaginally, surgical repair gives a good result.

BACKGROUND: Hyperbaric oxygen therapy (HBOT) delivers 100% oxygen in a pressurized chamber, increasing tissue oxygen levels and regulating inflammatory pathways. Mounting evidence suggests that HBOT may be effective for inflammatory bowel disease. Our systematic review and meta-analysis aimed to quantify the efficacy and safety of HBOT in fistulizing Crohn's disease (CD). METHODS: A systematic review was conducted using the EMBASE, Web of Science, Pubmed, and Cochrane Library databases according to the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" criteria. Study bias was assessed using the Cochrane Handbook guidelines. RESULTS: Sixteen studies with 164 patients were included in the analysis. For all fistula subtypes, the pooled overall clinical response was 87% (95% CI: 0.70-0.95, I2 = 0) and the pooled clinical remission was 59% (95% CI: 0.35-0.80, I2 = 0). The overall clinical response was 89%, 84%, and 29% for perianal, enterocutaneous, and rectovaginal fistulas, respectively. On meta-regression, hours in the chamber and the number of HBOT sessions were not found to correlate with clinical response. The pooled number of adverse events was low at 51.7 per 10,000 HBOT sessions for all fistula types (95% CI: 16.8-159.3, I2 = 0). The risk of bias was observed across all studies. CONCLUSION: HBOT is a safe and potentially effective treatment option for fistulizing CD. Randomized control trials are needed to substantiate the benefit of HBOT in fistulizing CD.

AIMS: Pulmonary vein isolation (PVI) is a well-established strategy for the treatment of paroxysmal atrial fibrillation (PAF). Despite randomized controlled trials and real-world data showing the promise of pulsed-field ablation (PFA) for this treatment, long-term efficacy and safety data demonstrating single-procedure outcomes off antiarrhythmic drugs remain limited. The aim of the FARA-Freedom Study was to evaluate the long-term efficacy and safety of PFA using the pentaspline catheter for PAF. METHODS AND RESULTS: FARA-Freedom, a prospective, non-randomized, multicentre study, enrolled patients with PAF undergoing de novo PVI with PFA, who were followed for 12 months with weekly transtelephonic monitoring and a 72-h Holter ECG at 6 and 12 months. The primary safety endpoint was a composite of device- or procedure-related serious adverse events out to 7 days post-ablation and PV stenosis or atrioesophageal (AE) fistula out to 12 months. Treatment success is a composite of acute PVI and chronic success, which includes freedom from any documented atrial tachyarrhythmia longer than 30â s, use of antiarrhythmic drugs or cardioversion after a 3-month blanking period, or use of amiodarone or repeat ablation at any time. The study enrolled 179 PAF patients (62 ± 10â years, 39% female) at 13 centres. At the index procedure, all PVs were successfully isolated with the pentaspline PFA catheter. Procedure and left atrial dwell times, with a 20-min waiting period, were 71.9 ± 17.6 and 41.0 ± 13.3â min, respectively. Fluoroscopy time was 11.5 ± 7.4â min. Notably, monitoring compliance was high, with 88.4 and 90.3% with weekly events and 72-h Holter monitors, respectively. Freedom from the composite primary effectiveness endpoint was 66.6%, and 41 patients had atrial tachyarrhythmia recurrence, mostly recurrent atrial fibrillation (31 patients). The composite safety endpoint occurred in two patients (1.1%), one tamponade and one transient ischaemic attack. There was no coronary spasm, PV stenosis, or AE fistula. There were four cases of transient phrenic nerve palsy, but all resolved during the index procedure. CONCLUSION: In this prospective, non-randomized, multicentre study, PVI using a pentaspline PFA catheter was effective in treating PAF patients despite rigourous endpoint definitions and high monitoring compliance and demonstrated favourable safety.

This study aimed to investigate the effect of laparoscopic and laparotomy extensive hysterectomy on the safety of ureterovaginal fistula infection in patients with cervical cancer. For this purpose, a total of 90 patients with early cervical cancer admitted to Affiliated Huaian No.1 People's Hospital of Nanjing Medical University from February 2021 to May 2022 were randomly divided into laparoscopy group and laparotomy group, with 45 cases in each group. The laparoscopy group was treated with laparoscopic extensive hysterectomy, while the laparotomy group was treated with laparotomy extensive hysterectomy. The KPS score, adverse reactions, as well as serum creatinine and urea nitrogen were compared between the two groups. Results showed that after surgery, the KPS score in both groups was higher than before treatment, and the KPS score in laparoscopy group was higher than that in laparotomy group, the difference was statistically significant (P<0.05). After operation, the incidence of adverse reactions in laparotomy group was higher than that in the laparoscopy group, the difference was statistically significant (P<0.05). Moreover, after operation, the levels of creatinine and urea nitrogen in laparoscopy group were significantly lower than those in laparotomy group, the differences were statistically significant (P<0.05). In conclusion, both laparoscopic and laparotomy extensive hysterectomy may lead to ureterovaginal fistula infection in patients with cervical cancer. However, compared with laparotomy extensive hysterectomy, laparoscopic extensive hysterectomy had higher safety and significantly improved the quality of life of patients, which was worthy of popularization and application in clinical practice.

Diverticular disease is common in Western countries; one-third of patients with diverticular disease develop diverticulitis during their lifetime of whom 5% may experience serious complications. We describe a rare complication of diverticulitis: a duodeno-colic fistula in a patient with an elongated sigmoid colon (dolicosigma). The patient complained of abdominal pain, diarrhea, weight loss, and feculent vomiting. Radiological studies and gastroscopy demonstrated a fistula between the second portion of the duodenum and the sigmoid colon. Curative surgery cured the fistula and completely resolved its associated signs and symptoms.

Anorectal malformations (ARMs) of the rectoperineal and rectovestibular fistula type (RPF/RVF) generally have a good prognosis but may be accompanied by bowel dysfunction, especially constipation. Bowel dysfunction in preschoolers may persist into adolescence and adulthood, exerting a negative effect on their quality of life. This study was designed to evaluate bowel function and identify the features of bowel dysfunction in preschoolers with RPF/RVF across type and sex differences. A total of 159 preschoolers with RPF/RVF (male RPF group, n = 95; female RPF group, n = 26; RVF, n = 38) and 128 normal control preschoolers (control group, n = 128; female control group, n = 35), according to the bowel function score (BFS) obtained through a questionnaire survey, the BFS items in the questionnaire, and the clinical characteristics of patients were compared among groups. The rates of bowel dysfunction (BFS < 17) were 27.2% and 50.0% in the RPF and RVF groups, respectively. Normal rates of BFS items, namely, ability to hold back defecation, feels/reports of the urge to defecate, frequency of defecation, and constipation, in the RPF and RVF groups were significantly lower than those in the control and female control groups (all p < 0.05). After subgroup analysis among the male RPF, female RPF, and RVF groups, higher rates of normal bowel function and ability to hold back defecation were found in the male RPF group than in the female RPF and RVF groups (p < 0.05). Normal rates of feels/reports of the urge to defecate were higher in the male and female RPF groups than in the RVF group (all p < 0.05). The rate of never soiling in the male RPF group was significantly higher than that in the RVF group (p < 0.05). Conclusions: In patients with RPF/RVF, bowel dysfunction is still prevalent, characterized by inadequate ability to hold back defecation, inability to feel/report the urge to defecate, soil, less frequent defecation, and constipation. However, male RPF patients had better overall bowel function than female RPF or RVF patients, including more adequate ability to hold back defecation and feels/reports of the urge to defecate and slighter soiling, which may be linked to early age at surgery, low occurrences of low sacral ratio, and tethered cord in male RPF. Trial registration: This study was retrospectively registered in ClinicalTrials.gov on 09/01/2023 (NCT05716230). What is Known: ⢠Rectoperineal and rectovestibular fistula (RPF/RVF) of the anorectal malformation (ARM) type has a good prognosis but may cause bowel dysfunction, especially constipation. ⢠Bowel dysfunction at preschool age may lead to social and psychological disorders that undermine the quality of life in adolescence and adulthood. What is New: ⢠Bowel function in preschoolers with RPF/RVF was deeply evaluated in a relatively large number of patients and normal control children. ⢠Features of bowel dysfunction in RPF/RVF preschoolers across type and gender differences were identified in this study.

BACKGROUND: Physicians and associate (non-physician) clinicians conduct cesarean sections in Tanzania and Malawi. Urogenital fistulas may occur as complications of cesarean section. Location and circumstances can indicate iatrogenic origin as opposed to ischemic injury following prolonged, obstructed labor. METHODS: This retrospective review assessed the frequency of iatrogenic urogenital fistulas following cesarean sections conducted by either associate clinicians or physicians in Tanzania and Malawi. It focuses on 325 women with iatrogenic fistulas among 1290 women who had fistulas after cesarean birth in Tanzania and Malawi between 1994 and 2017. An equivalence test compared the proportion of iatrogenic fistulas after cesarean sections performed by associate clinicians and physicians (equivalence margin = 0.135). Logistic regression was used to model the occurrence of iatrogenic fistula after cesarean section, controlling for cadre, date, maternal age, previous abdominal surgery and parity. RESULTS: Associate clinicians attended 1119/1290 (86.7%) cesarean births leading to fistulas, while physicians attended 171/1290 (13.3%). Iatrogenic fistulas occurred in 275/1119 (24.6%) cesarean births by associate clinicians and in 50/171 (29.2%) cesarean births by physicians. The risk difference and 90% confidence interval were entirely contained within an equivalence margin of 13.5%, supporting a conclusion of equivalence between the two cadres. The odds of iatrogenic fistula after cesarean section were not statistically significantly different between associate clinicians and physicians (aOR 0.90; 95% CI 0.61-1.33). CONCLUSIONS: Associate clinicians appear equivalent to physicians performing cesarean sections in terms of iatrogenic fistula risk. Lower iatrogenic proportions for associate clinicians could reflect different caseloads. The occurrence of iatrogenic fistulas illustrates the importance of appropriate labor management and cesarean section decision-making, irrespective of health provider cadre. Given the noninferior performance and lower costs of employing associate clinicians, other countries with insufficient and/or unequally distributed health workforces could consider task-shifting cesarean sections to associate clinicians.

BACKGROUND: The size selection of the arteriovenous (AV) anastomosis in dialysis access creation requires a careful balance: the diameter must be large enough to accommodate sufficient flow for hemodialysis but small enough to minimize the complication of steal syndrome. Steal syndrome affects up to 10% of patients after creation of dialysis access with sometimes devastating consequences. Conventional teaching recommends a 7-10 mm anastomosis. We sought to assess the efficacy of using a smaller (5-6 mm) anastomosis in new arteriovenous fistula (AVF) creation. METHODS: We conducted a comparative retrospective analysis of patients who underwent fistula creation with a small versus regular size anastomosis at any upper extremity anatomic site between March 2019 and October 2020 at our institution. Anatomic sites included radiocephalic, brachiocephalic, and brachiobasilic. All AV anastomoses were measured intraoperatively to be 5-6 mm in diameter for the small size groups and 8-10 mm for the regular size group. Endpoints included steal syndrome, functional patency, primary patency, and secondary patency. RESULTS: Out of 110 patients who underwent an AVF creation, 59.1% received a 5-6 mm anastomosis with a median follow-up time of 10 ± 6 months. Patients' demographics and comorbidities were relatively similar between the 2 groups except for a higher rate of hyperlipidemia (55.4% vs. 28.9%, P = 0.008) in the small size group. Patients in the small size group were more likely to undergo a radiocephalic fistula (40% vs. 4.5%, P < 0.001) and to have a smaller mean vein diameter on preoperative duplex ultrasound (3.2±1 mm vs. 3.9±1 mm, P = 0.0016) when compared to their regular size counterparts. During follow-up, none of the patients in the small group developed steal syndrome (0% vs. 9%, P = 0.015). At 1 year, patients in the regular size group achieved higher rates of primary patency (67.9% vs. 46.9%, P = 0.02); however, no difference was seen in 1-year primary-assisted patency (84.9% vs. 73.6%, P = 0.3), secondary patency (89.6% vs. 79.5%, P = 0.3), or functional patency (87.7% vs. 82.2%, P = 0.64) between the small and regular size groups, respectively. CONCLUSIONS: The use of a 5-6 mm anastomosis in the creation of new AVFs of the upper extremities appears to be a technically safe option for dialysis access. Our experience suggests that smaller anastomosis still creates enough flow to maintain a functional AV access while minimizing the incidence of steal syndrome. Additionally, even with smaller vein sizes preoperative, adequate dialysis access can be created via a small sized anastomosis, including distal arm access. Larger studies with longer follow-up are needed to evaluate long-term outcomes of small anastomosis fistulas.

BACKGROUND: Thoracogastric airway fistula (TGAF) is a fatal complication after esophagectomy. Without active treatment, patients may die of intractable pneumonia, sepsis, massive hemoptysis, or respiratory failure. We determined the clinical value of the two-tube method that involves the precise interventional placement of the nasojejunal tube (NJT) and nasogastric tube (NGT) for TGAF. METHODS: Clinical data of patients with TGAF who had undergone fluoroscopic interventional placement of NJT and NGT were analyzed retrospectively. The paired t-test was used to compare the index values before and after treatment. Statistical significance was set at p < 0.05. RESULTS: In total, 212 patients (177 male and 35 female; mean age, 61.3 ± 7.9 years [47-73]) with TGAF who had undergone the two-tube method were included. Posttreatment chest spiral computed tomography and inflammatory indicators showed significantly improved pulmonary inflammation compared with that before treatment. The patients' general condition remained stable. Of 212 patients, 12 (5.7%) underwent surgical repair, 108 (50.9%) received placement of airway stents, and 92 (43.4%) cases only continued treatment with the two-tube method owing to patients' conditions. In total, 47.8% (44/92) patients died of secondary pulmonary infection, bleeding, and primary tumor progression, whereas 52.2% (48/92) patients survived with both tubes. CONCLUSION: The two-tube method, which involves the precise interventional placement of the NJT and NGT, is simple, safe, and effective for treating TGAF. This method is a bridge for successive treatments or a treatment itself for patients who are unsuitable for surgical repair or stent placement.

STUDY OBJECTIVE: Surgical excision of large deep endometriosis nodules infiltrating the bladder may be challenging, particularly when the nodule limits are close to the trigone and ureteral orifice. Bladder nodules have classically been approached abdominally. However, combining a cystoscopic with an abdominal approach may help to better identify the mucosal borders of the lesion to ensure complete excision without unnecessary resection of healthy bladder. This study aimed to compare classical excision of large bladder nodules by abdominal route with a combined cystoscopic-abdominal approach. DESIGN: Retrospective comparative study on data prospectively recorded in a database. Patients were managed from September 2009 to June 2022. SETTING: Two tertiary referral endometriosis centers. PATIENTS: A total of 175 patients with deep endometriosis infiltrating the bladder more than 2 cm undergoing surgical excision of bladder nodules. INTERVENTIONS: Excision of bladder nodules by either abdominal or combined cystoscopic-abdominal approaches. MEASUREMENTS AND MAIN RESULTS: A total of 141 women (80.6%) were managed by abdominal route and 34 women (19.4%) underwent a combined cystoscopic-abdominal approach. In 99.4% of patients, the approach was minimally invasive. Patients with nodules requiring the combined approach had a lower American Fertility Society revised score and endometriosis stage and less associated digestive tract nodules, but larger bladder nodules. They were less frequently associated with colorectal resection and preventive stoma. Operative time was comparable. The rate of early postoperative complications was comparable (8.8% vs 22%), as were the rates of ureteral fistula (2.2% vs 2.9%), bladder fistula (2.2% vs 0), and vesicovaginal fistula (0.7% vs 2.9%). CONCLUSION: In our opinion, the combined cystoscopic-abdominal approach is useful in patients with large bladder nodules with limits close to the trigone and ureteral orifice. These large deep bladder nodules seemed paradoxically associated to less nodules on the digestive tract, resulting in an overall comparable total operative time and complication rate.

OBJECTIVE: To analyze the clinical characteristics and types of congenital heart defect (CHD) in mild congenital anorectal malformation (CARM), namely the rectoperineal and rectovestibular fistulas. METHODS: The retrospective study of 183 patients with mild CARM was conducted with assessments of demographic information, color Doppler echocardiography results, and follow-up data. We performed an analysis of the clinical characteristics of CHD, grouping them based on sex and type of mild CARM. RESULTS: Of the 183 patients, rectoperineal fistula occurred in 133 patients (72.7%), while the frequency of CHD was 79.8% (146/183). Ventricular septal defects (VSDs) occur more frequently in patients with rectoperineal fistula compared to those with rectovestibular fistula (1.5% vs. 10%), while the opposite trend was observed for patent ductus arteriosus (PDAs) (39.8% vs. 22.0%). Additionally, males presented higher frequency of PDA (42.7% vs. 26.4%) and self-healing (6 months: 87.2% vs. 42.6%; 12 months: 91.0% vs. 63.2%) than females. However, males had a lower rate of undergoing cardiac surgery (6.4% vs. 17.6%) and a younger median diagnosis age (1 day vs. 9 days). CONCLUSION: Our study indicates that there is a necessity for meticulous cardiac assessment and follow-up in neonates diagnosed with mild CARM.

BACKGROUND: The ventriculoperitoneal shunt (VPS) is the gold-standard surgical technique to treat hypertensive hydrocephalus; however, it may fail in 20 to 70% of cases. The present study shows an alternative for patients with contraindications to VPS. METHODS: A case series of nine patients. The medical records of all patients under 17 years of age who underwent ventriculo-gallbladder (VGB) shunt at a pediatric hospital from January 2014 to October 2022 were reviewed. RESULTS: There were 6 (66.7%) males and 3 (33.3%) females. The average age of 73.6 months or 6.1 years at the time of surgery. They had undergone, on average, 5.1 VPS reviews before the VGB shunt. Five (55.5%) had complications of VGB shunt: infection (11.1%), atony (11.1%), hypodrainage (11.1%), and ventriculoenteric fistula (22.2%); all these patients got better at surgical reapproach, and in two of them, the VGB shunt was re-implanted. CONCLUSION: This case series shows a lower risk of death and a similar risk of complications compared to other alternative shunts. This article spotlighted VGB as a viable alternative when VPS fails or has contraindications.

In this case report, we aimed to describe the clinical presentation, surgical approach, and follow-up of a patient with rare anterior meningocele associated with rectothecal fistula. An 17-year-old female patient was admitted to the emergency department with meningitis. On further examinations, an anterior sacral meningocele accompanied by rectothecal fistula was detected. Appropriate antibiotic treatment was arranged and surgical plan was made with the pediatric surgery clinic. The patient underwent meningocele repair via posterior approach and colostomy operation. The patient did not experience any neurological issues after the surgery. The colostomy was reversed 3 months later, and third-month follow-up MRI showed complete regression of the meningocele sac with no neurological complications. Anterior meningocele accompanied by a rectothecal fistula is a rare and complicated case. Only seven cases of coexisting ASM and RTF have been reported in literature. Although both anterior and posterior approaches have been used for the treatment of ASM, the choice of treatment is essentially based on the patient's clinical and imaging findings.
