Covid-19 infection in pregnant women in Dubai: a case-control study.

BACKGROUND: Whilst the impact of Covid-19 infection in pregnant women has been examined, there is a scarcity of data on pregnant women in the Middle East. Thus, the aim of this study was to examine the impact of Covid-19 infection on pregnant women in the United Arab Emirates population. METHODS: A case-control study was carried out to compare the clinical course and outcome of pregnancy in 79 pregnant women with Covid-19 and 85 non-pregnant women with Covid-19 admitted to Latifa Hospital in Dubai between March and June 2020. RESULTS: Although Pregnant women presented with fewer symptoms such as fever, cough, sore throat, and shortness of breath compared to non-pregnant women; yet they ran a much more severe course of illness. On admission, 12/79 (15.2%) Vs 2/85 (2.4%) had a chest radiograph score [on a scale 1-6] of ≥3 (p-value = 0.0039). On discharge, 6/79 (7.6%) Vs 1/85 (1.2%) had a score ≥3 (p-value = 0.0438). They also had much higher levels of laboratory indicators of severity with values above reference ranges for C-Reactive Protein [(28 (38.3%) Vs 13 (17.6%)] with p < 0.004; and for D-dimer [32 (50.8%) Vs 3(6%)]; with p < 0.001. They required more ICU admissions: 10/79 (12.6%) Vs 1/85 (1.2%) with p=0.0036; and suffered more complications: 9/79 (11.4%) Vs 1/85 (1.2%) with p=0.0066; of Covid-19 infection, particularly in late pregnancy. CONCLUSIONS: Pregnant women presented with fewer Covid-19 symptoms but ran a much more severe course of illness compared to non-pregnant women with the disease. They had worse chest radiograph scores and much higher levels of laboratory indicators of disease severity. They had more ICU admissions and suffered more complications of Covid-19 infection, such as risk for miscarriage and preterm deliveries. Pregnancy with Covid-19 infection, could, therefore, be categorised as high-risk pregnancy and requires management by an obstetric and medical multidisciplinary team.

Risk Factors for Surgical Site Infection after Operative Fixation of Acetabular Fractures: Is Psoas Density a Useful Metric?

BACKGROUND: Surgical site infection (SSI) occurs in 5% to 7% of patients undergoing operative fixation of acetabular fractures, with reported risk factors including longer operative duration, increased blood loss, pelvic artery embolization, and concurrent abdominal organ injury, among others. Psoas muscle density is a measure of muscle quality and, as a metric for sarcopenia and/or nutrition status, has been associated with poor outcomes such as mortality across multiple surgical specialties. To date, psoas muscle density has not been explored for its associations with SSI in acetabular fracture patients.Questions/purposes (1) Is decreased psoas muscle density, as measured by Hounsfield units, associated with an increased SSI risk after acetabular fracture fixation? (2) What patient, operative, and hospital variables are associated with an increased SSI risk after acetabular fracture fixation? METHODS: Between 2012 to 2017, surgeons performed 684 acetabular ORIF procedures at one level I trauma center. Of those, 8% (56 of 684) did not meet inclusion criteria, leaving 92% (n = 628) for analysis in this study. The median (range) follow-up duration was 12 months (0.5-77). Patient demographics, comorbidities, operative and in-hospital variables, and psoas muscle density measured using preoperative pelvic CT images-acquired for all operative acetabular fracture patients-were analyzed. SSI was defined by positive culture results obtained during irrigation and débridement. Overall, 7% (42 of 628) of patients had an SSI. A multivariable regression analysis was performed to identify independent risk factors. Sensitivity analysis was performed with minimum follow-up set at 3 months and 6 months. RESULTS: There was no difference in the mean psoas muscle density between patients with SSI (50.9 ± 10.2 Hounsfield units [HUs]) and those who did not have an SSI within 1 year of open reduction and internal fixation (51.4 ± 8.1 HUs) (mean difference: 0.5 [95% confidence interval -2.34 to 3.32]; p = 0.69). Four variables were independently associated with an increased risk of SSI: increased operative time (1.04 [95% CI 1.00 to 1.07]; p = 0.03), estimated blood loss (1.08 [95% CI 1.02 to 1.14]; p = 0.01), female sex (2.34 [95% CI 1.19 to 4.60]; p = 0.01), and intravenous drug use (3.95 [95% CI 1.51 to 10.33]; p = 0.01). Sensitivity analysis showed no change in results using either 3-month or 6-month minimum follow-up. CONCLUSIONS: Risk factors for SSI after acetabular fixation include female sex, intravenous drug use, prolonged operative times, and increased intraoperative blood loss. Although the density of the psoas muscle may be a surrogate for nutritional markers, it was not associated with SSI in our patients with acetabular fractures. Thus, it is not useful for risk assessment of SSI in the general population with acetabular fracture; however, future studies with larger sample sizes of patients older than 60 years may re-investigate this marker for SSI risk. Contrary to the results of previous studies, pelvic artery embolization, intraoperative blood transfusion, and intensive care unit stay did not increase the risk of SSI; however, we may have been underpowered to detect differences in these secondary endpoints. Future large, multisite studies may be needed to address these conflicting results more definitively. LEVEL OF EVIDENCE: Level III, therapeutic study.

Survival Outcomes of Very Small Drug-Eluting Beads Used in Chemoembolization of Unresectable Hepatocellular Carcinoma.

PURPOSE: To assess the safety and efficacy of transarterial chemoembolization using a 75-µm drug-eluting embolic (DEE) in patients with unresectable hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The medical records of 109 patients with a mean age of 64.1 years (range 85-49) treated for unresectable HCC between November 2013 and August 2016 with transarterial chemoembolization using a 75-µm DEE were retrospectively reviewed. Patients who had prior therapy for HCC were excluded. Child-Pugh A patients and Barcelona Clinic Liver Cancer stages A/B patients constituted 68.8% and 65.1% of the patients, respectively. The mean size of the index tumors was 5.8 cm (range 18.5-1.2) with 42 (39%) patients with central tumors around the porta-hepatis region. Portal vein invasion was seen in 10 (9.2%) patients. Tumor response was categorized according to the modified Response Evaluation Criteria in Solid Tumors 1.1, and the toxicity profile was assessed using Common Terminology Criteria for Adverse Events, version 4.03. RESULTS: At 1-month follow-up, complete response, objective response, and disease control was seen in 23%, 66%, and 90%, respectively. The median progression-free survival was 11.2 months. The median overall survival was 25.1 months (33.4 months for Child-Pugh A and 28.2 months for Barcelona Clinic Liver Cancer stages A/B), and transplant-free survival was 21.3 months. The 6-, 12-, and 24-month survivals were 91.7%, 75.5%, and 50.5%, respectively. Grade 3 toxicity was seen in 1.8% of the patients; no grade 4 or 5 toxicity was reported. CONCLUSIONS: Transarterial chemoembolization using 75-µm DEE is safe and efficacious in the treatment of HCC.

Psoas Muscle Density in Combination with Model for End-Stage Liver Disease Score Can Improve Survival Predictability in Transjugular Intrahepatic Portosystemic Shunts.

PURPOSE: To examine the role of psoas muscle density (PD) measurement before transjugular intrahepatic portosystemic shunt (TIPS) creation in predicting survival when combined with Model for End-stage Liver Disease (MELD) score. MATERIALS AND METHODS: The medical records of 241 patients with cirrhosis who underwent TIPS creation between June 2005 and June 2015 were retrospectively reviewed. The patients were divided into 2 groups: those with variceal bleeding (VB; n = 113) and those with volume overload (VO; n = 128). The study included 149 men (62%), and mean patient age was 56 years ± 9.6 (range 24-83). Mean MELD score before TIPS creation was 11.8 ± 5.7. A threshold sensitivity of pre-TIPS PD for the assessment of mortality was calculated and then correlated with survival after TIPS creation. Receiver operating characteristic curves comparing 12-month mortality were used to assess the improvement in survival predictability after TIPS creation when the PD threshold was combined with MELD score vs MELD score alone. RESULTS: Mean post-TIPS follow-up was 29.9 month ± 34.1 (range 1-3700 days). There was no significant difference in 3- or 12-month mortality rates between the VB and VO groups (32.7% vs 25.8% [P = .23] and 46% vs 46.1% [P = .99], respectively). The MELD score threshold for prediction of survival was 15 (P < .0001). There was no difference in the mean PD between VB and VO groups (34.2 HU ± 8.8 and 33.1 HU ± 10.3, respectively; P = .359). The increase in MELD score after TIPS creation was significant in both groups (VB, P = .0013; VO, P < .0001). The threshold of pre-TIPS PD for discrimination of survival was 29.4 HU (P < .0001), and PD measurements greater than this threshold were associated with a lower risk of mortality (hazard ratio, 0.27; 95% confidence interval, 0.13-0.57; P = .0006). Compared with the use of MELD score alone, the addition of PD measurement significantly increased the area under the curve from 0.61 to 0.68 (P = .0006). CONCLUSIONS: Measurement of PD improved overall survival predictability in patients with cirrhosis undergoing TIPS creation when used in conjunction with MELD score. The best survival outcome was observed in patients with MELD score < 15 in combination with PD > 29.4 HU.

Does Tramadol Increase the Severity of Nicotine Dependence? A Study in an Egyptian Sample.

In Egypt, tramadol abuse is increasing, especially among youths and the middle- aged. Tobacco smoking is a worldwide health problem responsible for more deaths and disease than any other noninfectious cause. To investigate if there is a relationship between tramadol and nicotine dependence. 48 tramadol addicts completed a demographic sheet, drug use questionnaire, and the Fagerstrom Test for Nicotine Dependence (FTND). Numbers of cigarettes smoked were recorded every week or two weeks at follow-up or by phone calls, and the FTND was completed again five weeks after abstinence. All participants underwent full psychiatric assessment, plus a urine toxicology screening at first visit, and once again during follow-ups. All subjects of the study were cigarette smokers. The mean numbers of cigarettes smoked per day were 13, 31.8, 20.2, and 14.3 during the phase before tramadol taking, addiction phase, two weeks and five weeks after stopping tramadol. The mean FTND score dropped from 6.67 during the tramadol addiction phase to 4.31 only five weeks after stopping tramadol. Tramadol increases the severity of nicotine dependence. The relation seems to be bi-directional, so increased cigarette smoking also increases tramadol intake.

Urolithiasis-related ureteric intussusception: A rare case report.

Ureteral intussusception is a rare condition that historically occurs as a complication of ureteral neoplasms or iatrogenic endoscopic procedures. Although the exact mechanism of ureteral intussusception is unclear, most reported cases are due to leading points as malignant or benign masses. Urolithiasis related is rarely reported and can be challenging in stone management as it might decrease the spontaneous stone passage rate. In addition, it will increase the complexity of the endoscopic stone management. We present the second reported case of urolithiasis-related ureteric intussusception presented with urosepsis due to obstructive uropathy, successfully managed by an endourological approach.

Contemporary Insights into Intractable Epilepsy in Children.

While most children with epilepsy find their seizures manageable through medication, some continue to experience seizures despite trying multiple drugs. Failure of medical treatment often becomes apparent early on, and for these cases, it is advisable to seek further treatment options at a specialized epilepsy center. Such centers offer additional treatments like epilepsy surgery, vagus nerve stimulation, and ketogenic diets. There is no universal definition for what constitutes "medically intractable" epilepsy. A proposal by a task force from the International League Against Epilepsy suggests that drug-resistant epilepsy could be defined as the inability to control seizures even after two adequate treatment attempts with well-chosen and tolerated medications, either alone or in combination. In this review, the authors discussed the management of intractable epilepsy in children.

Could the Crosstalk Between Myeloid-Derived-Suppressor Cells and Regulatory T Cells Have a Role in Beta-Thalassemia?

Background: Secondary iron overload, alloimmunization, and increased risk of infection are common complications in patients with transfusion-dependent thalassemia (TDT). Regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs) play an essential role in preventing excessive immune response. This research aimed to study the interaction between Tregs and MDSCs in TDT patients and to evaluate the association of these cell types with disease severity. Methods: This case-control study included 26 patients with TDT and 23 healthy, age- and sex-matched controls. All patients were investigated for complete blood count (CBC), serum ferritin, and flow cytometric analysis of peripheral blood to detect Tregs, MDSCs, and MDSC subsets. Results: A significant increase was observed in the frequencies of Tregs and MDSCs, particularly monocytic MDSCs (MO-MDSCs), in TDT patients compared with controls. The frequencies of these cells showed a direct association with ferritin level and total leukocyte count and an inverse association with hemoglobin level. Furthermore, a positive correlation was observed between Tregs and each of the total MDSCs and MO-MDSCs. Conclusions: Levels of Tregs and MDSCs increased in TDT and may probably have a role in suppressing the active immune systems of TDT patients.

Outcomes of transjugular intrahepatic portosystemic shunt using 12 mm diameter polytetrafluoroethylene covered stents in cirrhotic patients with portal hypertension.

PURPOSE We aimed to evaluate the safety and efficacy of 12 mm diameter polytetrafluoroethylene (PTFE)- covered stents for the creation of transjugular intrahepatic portosystemic shunt (TIPS) in cir- rhotic patients with portal hypertension complicated by variceal bleeding and volume-overload. METHODS This retrospective study included 360 patients who had TIPS created between January 2004 and December 2017 using 12 mm diameter PTFE-covered stents. Demographic data, model for end- stage liver disease (MELD) score, etiology of cirrhosis, and Charlson comorbidity index were recorded. Symptoms of hepatic encephalopathy (HE), variceal re-bleeding, improvement in vol- ume-overload, TIPS revisions and the need for intervention, and overall survival were assessed. RESULTS The mean age of the patients was 56.8 ± 9.9 years, and the technical success rate was 99.4%. The rates of improvement of volume-overload post-TIPS were 59.5%, 69.8%, and 81.7% at 3, 6, and 12 months, respectively. About 93.3% of patients were free from paracentesis or thoracentesis at 12 months. The rates of re-bleeding post-TIPS were 4%, 12%, and 12.9% at 3, 6, and 12 months, respectively. The rate of TIPS revision at 12 months was 6.5%. Percentage of patients with any symptoms of HE were 34.4%, 42.9%, and 49.5% at 3, 6, and 12 months, respectively. All HE were appropriately medically managed and no patients required a TIPS reduction. CONCLUSION TIPS placement using 12 mm PTFE-covered stents is efficacious in cirrhotic patients with portal hypertension complicated by variceal bleeding or refractory volume-overload, with an accept- able safety profile.

A Rare Presentation of Stauffer's Syndrome Associated with Renal Cell Carcinoma.

Renal cell carcinoma (RCC) is a primary tumor of the kidneys. It is characterized by the triad of flank pain, hematuria, and a palpable flank mass. However, most RCC patients present with a paraneoplastic manifestation of the disease. Stauffer's syndrome (a non-metastatic hepatic dysfunction) is a rare paraneoplastic manifestation associated with RCC. We report the case of a 30-year-old male, obese, who presented with hematuria and was found to have a right renal mass secondary to RCC. During his hospital stay, the patient developed acute hepatic dysfunction that resolved rapidly after tumor resection.

Leiomyosarcoma: a rare presentation as multifocal lesion.

Leiomyosarcoma is a rare type of connective tissue cancer, accounting for 5-10% of all soft tissue sarcomas. We present a case of leiomyosarcoma as unusual multifocal presentation. Retroperitoneal, mediastinal, pulmonary, uterine and bony regions were all involved at the time of presentation. The liver was normal without detected lesions.

Endovascular Management of Neurofibromatosis Type I-Associated Vasculopathy: A Case Series and Brief Review of the Literature.

PURPOSE: Neurofibromatosis type 1 (NF1) is an autosomal-dominant disorder found in approximately 1 of every 3000 individuals. Neurofibromatosis type 1 can have vascular manifestations including aneurysms, stenoses, and arteriovenous malformations. The purpose of this article is to describe the clinical manifestations of NF1 vasculopathy, discuss therapeutic options, and highlight endovascular therapies from our institutional experience. MATERIALS AND METHODS: The radiology information system was searched for cases of NF1. Cases with vasculopathy managed with endovascular therapies were included. Demographics, clinical histories, procedural details, and outcomes were recorded. A review of the literature for the management strategies of NF1 vasculopathy was performed. RESULTS: Two pediatric patients with NF1 were identified, both of whom presented with hypertension found to be secondary to renal artery stenosis. One of the patients also had infrarenal aortic narrowing. Both patients were successfully treated with balloon angioplasty, resulting in improved blood pressures. The review of the literature identified case series of pharmacologic, surgical, and endovascular therapies, although, endovascular therapies appear to be preferred due to lower morbidity and mortality. CONCLUSIONS: NF1 vasculopathy is a rare condition that most often presents with hypertension due to renal artery stenosis. In these situations, endovascular management is the preferred approach.

Comparative Study on the Outcomes of Elective-Start versus Urgent-Start Peritoneal Dialysis Catheter Placement.

The aim of this study is to compare the outcomes of the elective-start versus urgent-start use of peritoneal dialysis (PD) catheters using percutaneous radiologic or laparoscopic techniques. Patients having their first peritoneal dialysis catheter placed and used between January 2005 and January 2018 were identified, and their medical records were retrospectively reviewed. Two groups were identified: elective-start (n = 211) and urgent-start (n = 29). Patient's demographics were similar between the two groups with the exception of age, which was higher in the elective-start group. The catheter complication rates and catheter removal rates at 3 and 12 months, mean days-to-first complication, mean days-to-catheter removal, and overall patient survival at 12 months were analyzed. Catheter complication rates at 3 and 12 months were similar between the two groups (27.8% and 48.9%, respectively, in the elective-start group versus 35.9% and 54.2%, respectively, in the urgent-start group, p=0.415). The catheter removal rates at 3 and 12 months were also similar between the two groups (p=0.088). Catheter leak was higher in the urgent-start group (13.8% versus 3.3%, respectively, p=0.011). There was no difference between the elective-start and the urgent-start groups in the mean days-to-first complication (95 vs 69, p=0.086), mean days-to-catheter removal (145 vs 127, p=0.757), and overall patient survival at 12 months (100% vs 97%, p=0.41). In conclusion, apart from catheter leak, there were similar rates of catheter complication and removal for PD catheter used for the elective-start compared to the urgent-start PD. Furthermore, the technique of placement did not affect the outcomes.

Additive value of 3D-echo in prediction of immediate outcome after percutaneous balloon mitral valvuloplasty.

BACKGROUND: Results of percutaneous balloon mitral valvuloplasty (BMV) are basically dependent on suitable patient selection. Currently used two-dimensional (2D) echocardiography (2DE) scores have many limitations. Three-dimensional (3D) echocardiography (3DE)-based scores were developed for better patient selection and outcome prediction. We aimed to compare between 3D-Anwar and 2D-Wilkins scores in mitral assessment for BMV, and investigate the additive value of 3DE in prediction of immediate post-procedural outcome. Fifty patients with rheumatic mitral stenosis and candidates for BMV were included. Patients were subjected to 2D- and real-time 3D-transthoracic echocardiography (TTE) before and immediately after BMV for assessing MV area (MVA), 2D-Wilkins and 3D-Anwar score, commissural splitting, and mitral regurgitation (MR). Transesophageal echocardiography (TEE) was also undertaken immediately before and intra-procedural. Percutaneous BMV was performed by either multi-track or Inoue balloon technique. RESULTS: The 2DE underestimated post-procedural MVA than 3DE (p = 0.008). Patients with post-procedural suboptimal MVA or significant MR had higher 3D-Anwar score compared to 2D-Wilkins score (p = 0.008 and p = 0.03 respectively). The 3D-Anwar score showed a negative correlation with post-procedural MVA (r = - 0.48, p = 0.001). Receiver operating characteristic (ROC) curve analysis for both scores revealed superior prediction of suboptimal results by 3D-Anwar score (p < 0.0001). The 3DE showed better post-procedural posterior-commissural splitting than 2DE (p = 0.004). Results of both multi-track and Inoue balloon were comparable except for favorable posterior-commissural splitting by multi-track balloon (p = 0.04). CONCLUSION: The 3DE gave valuable additive data before BMV that may predict immediate post-procedural outcome and suboptimal results.

Percutaneous Cryoablation of Stage T1b Renal Cell Carcinoma: Safety, Technical Results, and Clinical Outcomes.

PURPOSE: The use of percutaneous cryoablation for T1b (4.1-7.0 cm) renal cell carcinoma, has not yet been widely adopted. The purpose of this study was to describe our experience in the cryoablation of stage T1b tumors with an emphasis on safety, technical results, and clinical outcomes. MATERIALS AND METHODS: A retrospective review of hospital records identified 37 patients who underwent cryoablation for T1b lesions from 2008 to 2018. Patient demographics, comorbidities, tumor characteristics, technical parameters, and outcomes were recorded and analyzed. Recurrence-free, overall, and cancer-specific survival rates were estimated using the Kaplan-Meier method. RESULTS: Thirty-seven patients (22 males, 15 females; mean age 66.5 ± 11.3) with 37 T1b tumors (mean diameter 47.3 ± 6.3 mm) were included. A median of 3 probes were used (range: 1-7). Angio-embolization was used in 3/37 (8.1%) and 2/37 patients (5.4%) required hydrodissection. The mean number of total cryoablation procedures for each patient was 1.5 (median 1; range: 1-4). Technical success was achieved in 88.2% of patients. Recurrence-free survival was 96.5%, 86.1%, and 62.6% at 1, 2, and 3 years respectively. Cancer-specific survival was 100% at 1, 2, and 3 years respectively. Overall survival was 96.7%, 91.8%, and 77.6% at 1, 2, and 3 years respectively. Complications classified as CIRSE grade 2 or higher occurred in 6/37 (16.2%) patients. CONCLUSION: T1b cryoablation is associated with high rates of technical success, excellent cancer-specific survival, and an acceptable safety profile. LEVEL OF EVIDENCE: Level 4, Case Series.

Approaches for safe transarterial chemoembolization of multifocal hepatocellular carcinoma with retrograde flow in a retroportal artery.

We report a case of an 81-year-old woman with multifocal hepatocellular carcinoma who underwent transarterial chemoembolization. The patient had significant superior mesenteric artery (SMA) ostial stenosis, which led to retrograde flow in the retroportal artery to the SMA. The authors adopted several approaches to avoid potential nontarget embolization that might result from the change in the hemodynamics in the hepatoenteric arteries by initially stenting the SMA ostial stenosis as well as the use of the Surefire infusion system and balloon occlusion for delivery of chemoembolization material to tumors in the hepatic lobes. To our knowledge, the collective use of these approaches to avoid potential risks related to SMA ostial stenosis and retrograde flow in a retroportal artery has not been previously described in the literature.

Persistent Pulmonary Arteriovenous Malformations: Percutaneous Embolotherapy.

Pulmonary arteriovenous malformations (PAVM) are an uncommon entity that interventional radiologists may face in their clinical practice. Many of these lesions are treated successfully using endovascular techniques with satisfactory long-term results. However, some PAVMs respond poorly to initial interventional techniques. This article reviews the signs and symptoms of persistent PAVMs, illustrates different imaging modalities used to diagnose these lesions, and outlines mechanisms by which these lesions may persist. The article highlights techniques and embolic agents used for percutaneous transcatheter embolotherapy of persistent PAVMs and discuss the outcomes of these interventions.

Outcomes of fluoroscopic and ultrasound-guided placement versus laparoscopic placement of peritoneal dialysis catheters.

BACKGROUND: Several peritoneal dialysis catheter (PDC) placement techniques have been described. The objective of this study was to compare the fluoroscopy and ultrasound guidance technique with the laparoscopic technique. METHODS: We retrospectively reviewed the medical records of 260 patients who had their first PDC placed between January 2005 and June 2016. We compared the outcomes of the fluoroscopic and ultrasound-guided catheter placement technique (radiologic group, n = 50) with the laparoscopic catheter placement technique (laparoscopic group, n = 190). The primary endpoint was complication-free catheter survival at 365 days. Secondary endpoints were complication-free catheter survival at 90 days, overall catheter survival at 90 and 365 days, median days to first complication and median days to catheter removal. RESULTS: In the radiologic group, the complication-free catheter survival at 90 and 365 days was 64% and 48%, respectively, while in the laparoscopic group it was 71% (P = 0.374) and 53% (P = 0.494), respectively. Catheter malfunction was significantly higher in the laparoscopic group (30%) compared with the radiologic group (16%, P = 0.048). The overall catheter survival at 90 and 365 days was 76% and 52%, respectively, in the radiologic group, while in the laparoscopic group it was 88% (P = 0.0514) an 48% (P = 0.652), respectively. There was no significant difference in the median days to first complication and the median days to catheter removal between the two groups (P = 0.71). CONCLUSION: The technique of fluoroscopic and ultrasound-guided PDC placement is a clinically effective and safe alternative to laparoscopic catheter placement with similar survival and complication rates.
