Suture passer combined with two-hole laparoscopic peritoneal dialysis catheterization in patients undergoing peritoneal dialysis

Background Laparoscopic techniques are being widely applied for peritoneal dialysis (PD) catheter (PDC) placement. The suture passer is a novel fixation tool that aims to reduce catheter migration. We compared the clinical value of the suture passer combined with two-hole laparoscopic PDC placement to open surgical placement by evaluating preoperative and postoperative conditions, as well as the onset of complications in both groups. Methods A retrospective study was conducted including 169 patients who underwent PDC placement surgery from January 2021 to May 2023. Based on the method employed, patients were divided into two groups: the suture passer combined with a two-hole laparoscopy group (SLG) and the open surgical group (SG). Comprehensive patient information, including general data, preoperative and postoperative indicators, peritoneal function after surgery, and the incidence rate of complications, were collected and analyzed. Results The SLG showed a statistically significant decrease in operative time, intraoperative blood loss, and 6-month postoperative drift rate compared to the SG (p < 0.05). No statistically significant differences were observed between the two groups in terms of sex, age, primary disease, hospitalization time, hospitalization costs, preoperative and postoperative examination indicators, peritonitis, and omental wrapping. Conclusions Suture passer combined with two-hole laparoscopic PDC placement, characterized by simplicity and facilitating secure catheter fixation, was deemed safe and effective for patients undergoing PD. It reduces the catheter migration rate and improved surgical comfort. Overall, this technique demonstrates favorable outcomes in clinical practice.

Laparoscopic peritoneal dialysis catheter insertion with omentopexy-sparing the omentum in children.

Continuous ambulatory peritoneal dialysis is an important modality of renal replacement therapy in children. Catheter dysfunction (commonly obstruction) is a major cause of morbidity and is a significant concern that hampers renal replacement therapy. As omentum is a significant cause of obstruction, some recommend routine omentectomy during insertion of the peritoneal dialysis catheter. Omentopexy rather than omentectomy has been described in adults to spare the omentum as it may be needed as a spare part in many conditions. Laparoscopic approach is commonly preferred as it provides global evaluation of the peritoneal space, proper location of the catheteral end in the pelvis and lesser morbidity due to inherent minimally invasive nature. The aim of this study is to present the technique of laparoscopic peritoneal dialysis catheter placement in children with concurrent omentopexy. We retrospectively evaluated our patients who underwent laparoscopic placement of peritoneal dialysis catheter with concomitant omentopexy or omentectomy. A total of 30 patients were enrolled who received either omentectomy (n = 18) or omentopexy (n = 12). Four catheters were lost in the omentopexy group (33%) and 3 in the omentectomy group (17%), but none were related to omental obstruction. Three out of 4 patients in the omentopexy group and 2 out of 3 patients in the omentectomy group had a previous abdominal operation as a potential cause of catheter loss. Previous history of abdominal surgery was present in 6 patients (50%) in the omentopexy group and 3 patients (17%) in the omentectomy group. As omentum was associated with catheter failure, omentectomy is commonly recommended. Alternatively, omentopexy can be preferred in children to spare an organ that may potentially be necessary for many surgical reconstructive procedures in the future. Laparoscopic peritoneal dialysis catheter placement with concomitant omentopexy appears as a feasable and reproducible technique. Although the catheter loss seems to be higher in the omentopexy group, none was related with the omentopexy procedure and may be related to the higher rate of history of previous abdominal operations in this group.

A New, Safe, and Effective Technique for Percutaneous Insertion of a Peritoneal Dialysis Catheter.

A properly functioning peritoneal catheter is an essential element of effective peritoneal dialysis (PD). Currently, there are three techniques available for PD catheter placement, which include open surgery, laparoscopic surgery, and percutaneous catheter placement (PCP). Currently, no particular catheter placement approach has been proven with certainty to provide superior outcomes. We present a new modified PCP method with the use of the Veress needle covered with an intravascular catheter (IC) and preliminary clinical results of PD catheter placements with this new technique. The endpoints used in the study were 1-year technical survival of the catheter, and the incidence of early (1 month) mechanical as well as infection complications. The catheter was implanted in 24 patients. The catheter survival rate was 100%; however, in two cases, the catheters were removed due to complications not associated with PD treatment. No early mechanical complications such as bleeding, hematoma, perforations, internal organ damage, exit site leaks, or hernia in the place of insertion were observed. Similarly, no early infectious complications were observed. During the 1-year follow-up, no catheter migration occurred. Our results showed that the new PCP technique is a safe and easy procedure that minimizes the occurrence of both mechanical and infectious complications and ensures good catheter survival.

Minimally invasive peritoneal access: A new approach of catheter placement for peritoneal dialysis.

Catheter implantation techniques for peritoneal dialysis (PD) have advanced significantly in recent years. We aimed to analyze the survival and associated complications of catheters inserted using a new technique that is guided by ultrasound and fluoroscopy and requires minimal tissue dissection. The procedure was performed by nephrologists in the outpatient basis, we compared these results of the minimally invasive insertion with traditional implantation using trocars. A total of 152 PD catheters were placed in 152 patients with stage 5 chronic kidney disease; 62.5% of the patients were men, with a mean age of 56.6 ± 18.5 years. The following two methods were used: minimally invasive insertion (MI group, n = 73) and trocar insertion (T group, n = 79). Patients in both the groups were followed prospectively for 26 months from the date of the first implantation. Gender, age, and prevalence of diabetes mellitus were not significantly different between the groups, while the body mass index, presence of obesity, and abdominal scars from previous surgeries were higher in the MI group (p = 0.021). The incidence of catheter dysfunction was lower in the MI group compared to group T (6.8% vs 20.3%; p = 0.019). Exit site infection was also lower with the new technique (4.1% vs. 18.9%; p = 0.005). Further, the cumulative incidence of peritonitis also reduced with MI (p = 0.034). Finally, the overall catheter survival at 1 year was 89%, which has been shown as higher in group MI (95% vs 82% in group T; p = 0.025). The MI technique for catheter insertion showed low complication rates and excellent catheter survival as compared to traditional implantation methods; thus, it may be an alternative method for PD catheter placement.

Utilization of peritoneal dialysis for ventilated COVID-19 patients with acute kidney injury

BackgroundPeritoneal dialysis for acute kidney injury is not typically a first-line option for mechanically ventilated patients in the intensive care unit. This series investigates the technical feasibility and clinical implications of bedside peritoneal dialysis catheter placement and utilization for mechanically ventilated COVID-19 patients. MethodsPatient data was retrospectively collected on patient characteristics, hospital course, fluid balance, ventilatory mechanics and associated morbidity and mortality of qualifying patients at a single center from March to April of 2020. Peritoneal dialysis catheters were inserted at bedside in the ICU for use as the primary modality of renal replacement therapy. Ventilatory mechanics were obtained prior to catheter insertion and after the first dwell. Statistics were calculated using GraphPad Prism and Excel. ResultsSeven male ventilated patients ages 52–83 were included. They were primarily Hispanic (71.43%). Comorbidities included chronic kidney disease (14.29%), hypertension (57.14%), hyperlipidemia (42.86%), and diabetes (28.57%). There were no mortalities associated the procedure. All-cause mortality at the time of data collection was 42.8%. Two patients had delayed initiation of peritoneal dialysis due to bleeding. Ventilatory mechanics before and after the first dwell did not demonstrate a significant difference in required FiO2, PEEP, tidal volumes or PaO2 to FiO2 ratios (p = 0.9172, p = 0.7398, p = 0.0924, p = 0.7227). DiscussionBedside placement of catheters was performed quickly and safely. Peritoneal dialysis was utilized for the treatment of acute kidney injury in mechanically ventilated patients with COVID-19 without significantly impacting respiratory mechanics. Peritoneal dialysis should be considered for similar ICU patients needing renal replacement therapy.

7. ANALYSIS OF THE RESULTS OF LAPAROSCOPIC TUNNELLED PERITONEAL DIALYSIS CATHETER PLACEMENT

Abstract Introduction Peritoneal dialysis is a type of renal replacement therapy that improves quality of life and empowers patients with advanced chronic kidney disease. The best method of peritoneal dialysis catheter (PDC) placement remains to be defined. Methods Retrospective observational study from October 2019 to March 2023, aiming to analyse the results of this new technique for PDC placement in our centre. Results The study consisted of 45 patients, 66.7% of whom were men. The study comprised 45 patients, with 66.7% being men. The mean age was 57 years, and the mean BMI was 27.9 kg/m2, with 82.8% of the patients classified as ASA III. In 66.7% of cases, it was the first catheter to be placed. Of the surgeries conducted, 41 involved initial placements, and 4 involved laparoscopic repositioning, the latter following a previously unsuccessful Alpha manoeuvre. In 6 cases, an associated surgery was performed. The mean duration of surgery was 34 minutes, with a median length of stay of 24 hours. In 3 patients, catheter malfunction occurred, with 2 requiring laparoscopic repositioning and the remaining one laparoscopic replacement. Additionally, 3 other patients experienced infectious complications, which were treated conservatively. No major complications or laparoscopy conversions were noted. The mean follow-up from surgery was 15.4 months, with 42.2% of PDCs being removed after a mean of 11.5 months, and renal transplantation being the most common reason for removal (79%). Conclusion In our centre, tunnelled PDC placement has proven to be safe and effective, with a low percentage of infections, relocations or replacements, and it is considered the technique of choice for patients capable of undergoing surgery under general anaesthesia.

Minimizing early catheter failure using a risk stratification model for peritoneal dialysis.

Early catheter failure is the main reason for peritoneal dialysis (PD) failure, which often causes patients to withdraw from PD. Reducing the early catheter failure is critical to increase the acceptance of PD. The purpose of our study was to establish a risk stratification model to minimize early catheter failure. A retrospective study with patients underwent PD catheter placement from January 2013 to March 2022 was conducted. The primary outcome event was early catheter failure. Univariate and multivariable logistic regression were performed to select potential risk predictors. A risk stratification model and a clinical procedure were established. The effectiveness of the model was evaluated by external validation. A total of 432 patients were finally enrolled in the study. The risk for early catheter failure was associated with younger age (odds ratio [OR], 0.930; 95% confidence interval [95% CI], 0.884 to 0.972; p = 0.002), lower body mass index (BMI) (OR, 0.797; 95% CI, 0.629 to 0.964; p = 0.036), and lower albumin (ALB) levels (OR, 0.881; 95% CI, 0.782 to 0.985; p = 0.036). The risk stratification model was established and performed great discrimination capability with AUC of 0.832 (cut-off value: 0.061, sensitivity: 0.853, specificity: 0.812). The model proved to be effective in external validation; the rate of early catheter failure was dropped off from 4.1% to 0%. We established an effective risk stratification model, by which patients with high risk of early catheter failure could be precisely identified. The clinical procedure based on the model was proved to be helpful to minimize early catheter failure.

The prophylactic omentectomy procedure in reducing the complication rate of continuous ambulatory peritoneal dialysis in pediatric: A systematic review and meta-analysis.

The role of the omentectomy procedure on Continuous Ambulatory Peritoneal Dialysis (CAPD) catheter placement in pediatric patients has been differently evaluated in the literature, with some studies showing improvement while others showing no difference. Our study aims to define the advantages of omentectomy compared to a procedure without omentectomy. The literature searching in online databases (PubMed/MEDLINE, Cochrane Library, EMBASE, Scopus, and ClinicalTrial.gov) following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, has been registered on PROSPERO (CRD42023412846). The protocol was performed through April 2023 and focused on pediatric patients treated with an omentectomy procedure and related complications. The risk of bias in each study was assessed using the risk of bias for the non-randomized control trials (ROBINS-I). The effect estimates were extracted as risk ratios with 95% confidence intervals (CI). The heterogeneity of the studies was considered as high heterogeneity if I2 values above 50% or p < 0.05. In the total of 676 articles identified in the database searching for screening, nine studies with 775 patients met the criteria for inclusion. The omentectomy procedure significantly showed a lower incidence of catheter obstruction compared to the control group, (OR 0.24 [95% CI, 0.12-0.49], p < 0.0001, I2 = 0%). Moreover, omentectomy demonstrated a similar trend in the rate of removal or reinsertion of the catheter with high heterogeneity, OR 0.25 [95% CI, 0.12-0.51), p = 0.0002, I2 = 70%). The omentectomy procedure showed a lower incidence of catheter obstruction and complications leading to removal or reinsertion of the catheter.

Laparoscopic vs open surgical insertion of peritoneal dialysis catheters: A propensity score-matched cohort study

BackgroudThe optimal peritoneal dialysis (PD) catheterization method remains under debated. To minimize catheter-related complications, we developed a novel modified low-position two-port laparoscopic technique, and evaluated the efficacy and safety of traditional open and advanced laparoscopic techniques. MethodsA total of 743 patients with uremia who underwent PD catheterization were retrospectively reviewed. For the placement of PD catheters, patients underwent low-position two-port laparoscopic surgery (Lap group) or traditional open surgery (open group). To minimize confounding bias, we performed a 1-to-2 propensity-score matching adjusted for the most clinically relevant potential confounders. The baseline characteristics, perioperative conditions, complications and outcomes were compared between the two groups. ResultsAfter propensity-score matching, a well-balanced cohort comprising 148 matched pairs were identified. In the matched analysis, patients in the Lap group showed significantly shorter operative time (43.0 ± 16.6 versus 81.6 ± 19.8 minutes, P < 0.001) and lower postoperative pain score within 24 hours (0.24 ± 0.62 versus 1.00 ± 1.41, P = 0.002). The incidence of catheter migration in the Lap group was significantly lower than those in the open group (0.7% versus 6.5%, P = 0.006), while other complications, such as catheter occlusion, omentum wrapping, dialysate leakage, bloody effluent, organ injury, hernia, hydrothorax, early tunnel infection and peritonitis, showed no difference (P > 0.05). The Lap group patients had a favorable catheter survival rate compared with group B (log rank, P = 0.032). ConclusionsOur low-position two-port laparoscopic technique is a safe, simple, and fast method that can minimize patient discomfort without additional cost and offers better catheter survival with minimal risk of migration.

Conscious sedation anesthesia using different doses of remifentanil combined with dexmedetomidine for peritoneal dialysis catheter implantation

Background Conscious sedation anesthesia (CSA) is an anesthetic method during peritoneal dialysis catheter implantation. However, lack of optimal CSA strategies for patients with end-stage renal disease (ESRD). This study aimed to evaluate the analgesic effects and safety of CSA using different doses of remifentanil combined with dexmedetomidine during peritoneal dialysis catheter insertion. Methods Patients who underwent peritoneal dialysis (PD) catheter placement via open surgical incision were retrospectively analyzed and divided into three groups based on the tertile dose of remifentanil. The bispectral index (BIS) was used to monitor the depth of anesthesia. Data regarding clinical findings, the effects of anesthesia, and the incidence of drug-related adverse effects were collected. Results In total, 102 patients completed the surgery successfully and safely. The dose of remifentanil was 0.02–0.07 μg/kg/min, 0.08–0.13 μg/kg/min, and 0.14–0.20 μg/kg/min in Groups A, B, and C, respectively. Only seven patients reported mild pain during the surgery. No significant differences were observed among the numeric rating scale scores of the three groups (p > 0.05). Intraoperative hemodynamics were stable. The incidence of respiratory depression was 8.3%, 20.0%, and 41.9% in Groups A, B, and C, respectively (p < 0.01). The incidence of gastrointestinal symptoms in Group C (51.6%) was higher than that in Groups A and B (p < 0.05). Conclusion Low-dose remifentanil (0.02–0.07 μg/kg/min) combined with dexmedetomidine achieved satisfactory anesthetic effects with fewer adverse drug reactions during PD catheter implantation, indicating its potential for use in patients undergoing PD catheter placement.

Inpatient peritoneal dialysis catheters placed across the United States during a 3-year period: Lessons learned from 15,000 patients

BackgroundPeritoneal dialysis is a popular option for patients with end-stage renal disease. A recent presidential executive order has incentivized in-home end-stage renal disease treatments, leading to an increase in peritoneal dialysis use. Guidelines exist for creating and maintaining peritoneal dialysis access without addressing the optimal technique. This study evaluates nationwide peritoneal dialysis catheter placement practices and their long-term outcomes. MethodsRetrospective cohort analysis of Nationwide Readmission Database from 2017 to 2019. Patients with end-stage renal disease undergoing inpatient peritoneal dialysis catheter placement were included. Six-month readmissions, mortality, and peritoneal dialysis catheter-specific outcome measures were assessed among survivors of admission, including catheter leakage, mechanical breakdown, displacement, revision or replacement, removal, exit site infections, intra-abdominal abscess, and sepsis. Binary logistic regression analyses were performed. ResultsIn the study, 14,863 patients with inpatient peritoneal dialysis catheter insertions were identified, of which 7,096 were analyzed (4,150 [59%] laparoscopic, 1,781 [25%] fluoroscopic, 1,165 [16%] open), 847 (12%) had major complications, 931 (13%) were readmitted, and 102 (1.4%) died within 6 months. Univariate analyses demonstrated that laparoscopy had higher mechanical complications, exit-site infections, catheter revision, and removal within 6 months, and fluoroscopy had higher sepsis and mortality. Multivariate analyses showed fluoroscopy was associated with intraabdominal abscess (adjusted odds ratio, 2.36; P = .025), laparoscopy with exit-site infections (adjusted odds ratio, 0.49; P = .005), and open surgery with catheter displacement (adjust odds ratio, 2.95; P = .021). ConclusionThis is the first large-scale study on inpatient peritoneal dialysis catheter placement outcomes in the United States. Fluoroscopic and open surgical placements are routinely performed, but laparoscopy remains the mainstay with fewer exit-site infections. Overall, peritoneal dialysis is a safe option, with 1 in 9 patients having an infectious or mechanical complication within 6 months. Furthermore, large-scale prospective studies are warranted to identify the optimal placement technique.

Advanced Image-Guided Percutaneous Technique Versus Advanced Laparoscopic Surgical Technique for Peritoneal Dialysis Catheter Placement

Timely placement of a functional peritoneal dialysis (PD) catheter is crucial to long-term PD success. Advanced image-guided percutaneous and advanced laparoscopic techniques both represent best practice catheter placement options. Advanced image-guided percutaneous is a minimally invasive procedure that does not require general anesthesia. Retrospective cohort study comparing time from referral to procedure, complication rate, and 1-year catheter survival between placement techniques. Patients who had advanced laparoscopic or advanced image-guided percutaneous PD catheter placement from January 1, 2011 to December 31, 2013 in an integrated Northern California health care delivery system. PD catheter placement using advanced laparoscopic or advanced image-guided percutaneous techniques. One-year PD catheter survival; major, minor, and infectious complications; time from referral to PD catheter placement; and procedure time. Wilcoxon rank sum tests to compare referral and procedure times; χ2/Fisher exact tests to compare complications; and modified least-squares regression to compare adjusted 1-year catheter survival between PD placement techniques. We identified 191 and 238 PD catheters placed through advanced image-guided percutaneous and advanced laparoscopic techniques, respectively. Adjusted 1-year PD catheter survival was 80% (95% CI, 74%-87%) using advanced image-guided percutaneous technique vs 91% (87%-96%) using advanced laparoscopic technique (P=0.01). Major complications were<1% in both groups. Minor and infectious complications were 45.6% and 38.7% in advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P=0.01). Median days from referral to procedure were 12 and 33 for patients undergoing advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P<0.001). Median procedure time was 30 and 44.5 minutes for patients undergoing advanced image-guided percutaneous and advanced laparoscopic techniques, respectively (P<0.001). Retrospective study with practice preference influenced by timing, local expertise, and resources. Both advanced image-guided percutaneous and advanced laparoscopic techniques reported rare major complications and demonstrated excellent (advanced laparoscopic) and acceptable (advanced image-guided percutaneous) 1-year PD catheter survival. For patients referred for PD catheter placement at centers where advanced laparoscopic resources or expertise remain limited, the advanced image-guided percutaneous technique can provide a complementary and timely option to support the utilization of PD. Peritoneal dialysis is a preferred dialysis modality for many patients. However, the lack of available skilled surgeons can limit the placement of the peritoneal dialysis catheter in a timely manner. In the past decade, interventional radiology has developed expertise in placing peritoneal dialysis catheters. Using data from an integrated health care system, we compared the outcome of peritoneal dialysis catheters placed using laparoscopic surgery and interventional radiology techniques. Our results showed excellent 1-year patency of peritoneal dialysis catheters placed using laparoscopic surgery, whereas interventional radiology placement of catheters had lower but acceptable1-year patency survival, based on best practice guideline criteria. Hence, interventional radiology placement of peritoneal dialysis catheters may be a viable alternative when laparoscopic surgery is not available or feasible.

Complications and prognosis of patients diagnosed with autosomal recessive polycystic kidney disease in neonatal period.

There are no clinical guidelines for performing nephrectomy in patients with autosomal recessive polycystic kidney disease (ARPKD). Few reports have described the clinical course of ARPKD diagnosed in the neonatal period in detail. Here, we report seven patients diagnosed with ARPKD and treated at our center during the neonatal period. Two died within 48h of life due to pulmonary hypoplasia. Of the remaining five patients, three had anuria and required for kidney replacement therapy (KRT) within one week after birth, whereas two with a milder phenotype survived without KRT. All three patients who received KRT underwent unilateral nephrectomy and peritoneal dialysis (PD) catheter placement. To prevent fluid leakage, PD was initiated 7-14days after catheter placement. However, peritoneal leakage occurred in two patients, resulting in peritonitis and discontinuation of PD; one who required long-term hemodialysis contracted a catheter-related bloodstream infection as well as developed subdural and epidural hematomas. Meanwhile, two patients underwent a second nephrectomy within 6weeks after birth; one developed severe persistent hypotension and neurological complications, while the other died of bacteremia that may have resulted from cholangitis diagnosed on day 67 of life. A severe clinical course, life-threatening adverse events, and severe neurological sequalae may occur in patients with ARPKD who receive KRT in neonatal period.

Peritoneal Dialysis Catheter Complications after Insertion by Surgeons, Radiologists, or Nephrologists.

The Advancing American Kidney Health Initiative aims to increase rates of utilization of peritoneal dialysis (PD) in the United States. One of the first steps to PD is successful catheter placement, which can be performed by surgeons, interventional radiologists, or nephrologists. We examined the association between operator subspecialty and risk of needing a follow-up procedure in the first 90 days after initial PD catheter implantation. Overall, we found that 15.5% of catheters required revision, removal, or a second catheter placement within 90 days. The odds of requiring a follow-up procedure was 36% higher for interventional radiologists and 86% higher for interventional nephrologists compared with general surgeons. Further research is needed to understand how to optimize the function of catheters across different operator types. The US government has implemented incentives to increase the use of PD. Successful placement of PD catheters is an important step to increasing PD utilization rates. Our objective was to compare initial outcomes after PD catheter placement by different types of operators. We included PD-naïve patients insured by Medicare who had a PD catheter inserted between 2010 and 2019. We examined the association between specialty of the operator (general surgeon, vascular surgeon, interventional radiologist, or interventional nephrologist) and odds of needing a follow-up procedure, which we defined as catheter removal, replacement, or revision within 90 days of the initial procedure. Mixed logistic regression models clustered by operator were used to examine the association between operator type and outcomes. We included 46,973 patients treated by 5205 operators (71.1% general surgeons, 17.2% vascular surgeons, 9.7% interventional radiologists, 2.0% interventional nephrologists). 15.5% of patients required a follow-up procedure within 90 days of the initial insertion, of whom 2.9% had a second PD catheter implanted, 6.6% underwent PD catheter removal, and 5.9% had a PD catheter revision within 90 days of the initial insertion. In models adjusted for patient and operator characteristics, the odds of requiring a follow-up procedure within 90 days were highest for interventional nephrologists (HR, 1.86; 95% confidence interval [CI], 1.56 to 2.22) and interventional radiologists (odds ratio, 1.36; 95% CI, 1.17 to 1.58) followed by vascular surgeons (odds ratio, 1.06; 95% CI, 0.97 to 1.14) compared with general surgeons. The probability of needing a follow-up procedure after initial PD catheter placement varied by operator specialty and was higher for interventionalists and lowest for general surgeons.

Perception of Nephrology residency training in Peru

IntroductionIn the assessment of the second specialty training programs, the opinion of residents and graduates is essential to know the degree of satisfaction with the training received. The aimed was to assess the perceptions of Peruvian nephrology residents and graduates regarding their training. MaterialA descriptive, cross-sectional study included all final-year residents and graduates of the nephrology program in 2022. An anonymous virtual survey assessed sociodemographic aspects, nephrology tutoring, clinical training, external rotations, research, the impact of the COVID-19 pandemic, and overall perception of their training. ResultsWith a response rate of 79.68%, 51 participants were evaluated. 76.48% of the participants rated their overall training during the residency as good. 58% agreed or strongly agreed that their tutor's performance was good. 66.6% agreed or strongly agreed that their theoretical training was good, with less certainty in genetic kidney diseases. 90% agreed or strongly agreed that their practical training was good, with less certainty in training in slow therapies, renal biopsies, acute peritoneal dialysis, and peritoneal dialysis catheter placement. 80.4% agreed or strongly agreed that the pandemic affected their training. The general perception had a positive correlation with the tutor's performance as good (r=0.50; P<.001), the good perception of the hospital's research level (r=0.47, P<.001), and the perception of good opportunities to get a job as a nephrologist (r=0.67, P<.001). ConclusionAlthough, in general, the perception is positive, there are aspects in which the training of Peruvian nephrology residents should be improved.

Laparoscopic Inguinal Hernia Repair and Synchronous Peritoneal Dialysis Catheter Placement: A Single-Center Experience.

Background: Peritoneal dialysis (PD) is a common method for treating end-stage renal disease (ESRD). Occurrence of inguinal hernia before and during PD is considered to be the main cause of treatment discontinuation, failure, and conversion to hemodialysis. In this study, we present a single-center experience about laparoscopic inguinal hernia repair and synchronous PD catheter placement and evaluated the feasibility and outcomes. Methods: During May 2018 to May 2022, a total of 216 consecutive patients with ESRD underwent laparoscopic PD catheter placement. Among them, 41 patients (27.7%) with coexistent inguinal hernia were included in this study. Individual information, complications, recurrent and new-onset hernias, and catheter survival were retrospectively analyzed. Results: Forty-one patients underwent laparoscopic inguinal hernia repair and synchronous PD catheter placement, 9 patients had bilateral inguinal hernia, and another 32 patients had unilateral inguinal hernia. The mean age was 46.49 years (range, 28-72 years), including 39 males and 2 females. There was no recurrent hernia and only 1 patient (2.4%) developed incisional hernia (trocar site hernia) which required hernia repair and discontinuation of PD. No postoperative complications were observed, such as bleeding, infection, and dialysate leakage. After a median follow-up of 37 months (20-58 months), there were no deaths and 97.6% (40/41) catheters were still working. Conclusions: Laparoscopic hernia repair and synchronous PD catheter placement is an effective and safe treatment for ESRD patients with coexisting inguinal hernia in virtue of low postoperative complications and high catheter survival.

Modified Single Port Laparoscopic Peritoneal Dialysis Catheter Insertion - Initial Experience and Outcome from a Tertiary Care Centre

Background: Chronic kidney disease (CKD) and end-stage renal disease (ESRD) are emerging as a major health related issues in developing countries. The increasing numbers require rapid adaptation of existing health-care policies. The number of patients requiring renal care is only bound to increase in coming years with the increasing incidence and prevalence of diabetes. Continuous ambulatory peritoneal dialysis (CAPD) catheter placement is performed on end-stage renal disease (ESRD) patients. There is abundant literature regarding post-operative outcomes and re-operative rates following CAPD. We report our initial experience of modified single port laparoscopic technique of placing CAPD catheters using a single port through the Palmer’s point and discuss our surgical outcomes. Methods: This was a retrospective review (2019-2020) of patients undergoing CAPD catheter placement at SMVD Narayana Superspecialty Hospital. Outcome analysis focused on patient related outcomes, including early (&lt; 30 days) versus late (≥ 30 days) complication and re-operation rates. Results: A total of 30 patients with ESRD, (mean ASA score = 3.3) were included in the study who underwent modified single port laparoscopic (n = 30) CAPD catheter placement (mean follow-up = 180 days). The total complication rate with the procedure was 43%, with re-operation rate of 20%. CAPD catheter non-function occurred in 06 patients (20% of total). CAPD catheter migrations occurred in 03 patients (10% of total). CAPD catheter related infections occurred in 05 patients (16% of total), and 02 required re-operation; 03 patients were treated successfully with culture directed antibiotics. There were 2 deaths during the study period, one due to peritonitis and other due to underlying cardiac disease. There was no surgical mortality in the study group. Conclusion: Although CAPD catheter placement in patients with ESRD are technically un-complicated to accomplish, long term results suggest as many as one in three patients will struggle with some form of catheter malfunction or infection. Our modified technique and the results have led to changes in our CAPD catheter placement technique, as well as the post-operative patient care algorithm.

Transthoracic Echocardiography in the Preoperative Assessment of Newborn Coarctation: Limiting Risks Associated with Advanced Imaging Techniques.

A newborn male child with prenatally identified aortic arch hypoplasia presented to our facility for cardiac management. He had been started on prostaglandins at the delivery facility and was subsequently placed on a high-flow nasal cannula due to associated apnea. On the day of life three, the patient underwent cardiac computed tomography scan for delineation of his anatomy. The patient remained intubated after his imaging study in anticipation of surgical intervention, which took place at the age of 5 days. The patient required a peritoneal dialysis catheter placement 2 days after his procedure due to oliguria. He progressed into renal failure requiring continuous renal replacement therapy. This patient was subsequently discussed at our departmental morbidity and mortality conference. The short time frame between contrast administration for the computed tomography and surgical intervention was thought to have contributed to his renal failure. We discussed the adequacy of transverse aortic arch imaging by echocardiogram and the utility of advanced imaging in the fragile neonatal period. This discussion resulted in our department asking, "Is transthoracic echocardiography accurate when diagnosing and characterizing aortic coarctation at our institution? Are advanced imaging studies necessary in instances of simple coarctation?"
