Outcomes of laparoscopic and open ventriculoperitoneal shunt placement.

OBJECTIVE: Ventriculoperitoneal (VP) shunt placement requires a concurrent abdominal procedure. For peritoneal access laparoscopic or open approach may be utilized. Our aim was to compare patient/procedure characteristics and outcomes by peritoneal approach for VP shunts in children. METHODS: NSQIP-Pediatric procedure targeted cerebral spinal fluid shunt Participant Use Data Files from 2016 to 2020 were queried. Patients were grouped into laparoscopic vs open abdominal approach. Patient demographics, procedure characteristics and 30-day outcomes were compared. RESULTS: 7742 NSQIP-Pediatric patients underwent VP shunt placement. Patients undergoing laparoscopic approach were older and required less preoperative support. Mean operative time was longer with laparoscopy (mean(SD): 74.2(48.1) vs. 64.6(39) minutes, p â€‹< â€‹0.0001) but had shorter hospital LOS. There was no difference in SSI, readmissions, or reoperation rates. CONCLUSION: Patients undergoing laparoscopy for distal VP shunts are older with less support needs preoperatively. While laparoscopic approach had a shorter hospital LOS, there was no demonstratable difference in SSI, readmissions or reoperations between approaches. Further studies are needed to assess long-term outcomes.

Endoscopic Third Ventriculostomy and Endoscopic Intracranial Cyst Fenestration in an Outpatient Ambulatory Surgery Center Yields Reduced Cost But Equal Efficacy and Safety Compared with Surgery in the Hospital.

BACKGROUND: A transition is underway in neurosurgery to perform relatively safe surgeries outpatient, often at ambulatory surgery centers (ASC). We sought to evaluate whether simple intracranial endoscopic procedures such as third ventriculostomy and cyst fenestration can be safely and effectively performed at an ASC, while comparing costs with the hospital. METHODS: A retrospective chart review was performed for patients who underwent elective intracranial neuroendoscopic (NE) intervention at either a quaternary hospital or an affiliated ASC between August 2014 and September 2017. Groups were compared on length of stay, perioperative and 30-day morbidity, as well as clinical outcome at last follow-up. The total cost for these procedures were compared in relative units between all ASC cases and a small subset of hospital cases. RESULTS: In total, 16 NE operations performed at the ASC (mean patient age 29.8 years) and 37 at the hospital (mean age 15.4 years) with average length of stay of 3.5 hours and 23.1 hours respectively (P < 0.05). There were no acute complications in either cohort or morbid events requiring hospitalization within 30 days. Surgical success was noted for 75% of the ASC patients and 73% of the hospital cohort. The mean cost of 5 randomly selected hospital operations with same-day discharge and 5 with overnight stay was 3.4 and 4.1 times that of the ASC cohort, respectively (P < 0.05). CONCLUSIONS: Elective endoscopic third ventriculostomy and other simple NE procedures can be safely and effectively performed at an ASC for appropriate patients with significantly reduced cost compared with the hospital.

Converting Pediatric Patients and Young Adults From a Shunt to a Third Ventriculostomy: A Multicenter Evaluation.

BACKGROUND: Endoscopic third ventriculostomy (ETV) is an effective primary treatment for certain forms of hydrocephalus. However, its use in children with an existing shunt is less well known. OBJECTIVE: To report a multicenter experience in attempting to convert patients from shunt dependence to a third ventriculostomy and to determine predictors of success. METHODS: Three participating centers provided retrospectively collected information on patients with an attempted conversion from a shunt to an ETV between December 1, 2008, and April 1, 2018. Demographic, clinical, and radiological data were recorded. Success was defined as shunt independence at the last follow-up. RESULTS: Eighty patients with an existing ventricular shunt underwent an ETV. The median age at the time of the index ETV was 9.9 yr, and 44 (55%) patients were male. The overall success rate was 64% (51/80), with a median duration of follow-up of 2.0 yr (range, 0.1-9.4 yr). Four patients required a successful repeat ETV at a median of 1.7 yr (range, 0.1-5.7 yr) following the index ETV. Only age was predictive of ETV failure on multivariate analysis (odds ratio 0.86 [95% CI 0.78-0.94], P = .005). No patient less than 6 mo of age underwent an ETV, and of the 5 patients between 6 and 12 mo of age, 4 failed. CONCLUSION: Although not every shunted patient will be a candidate for an ETV, nor will they be successfully converted, an ETV should at least be considered in every child who presents with a shunt malfunction or who has an externalized shunt.
