Laparoscopy assisted ventriculoperitoneal shunt placement in children

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 ​< ​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.

Open versus laparoscopic ventriculoperitoneal shunt placement in children: a systematic review and meta-analysis

BACKGROUND

Ventriculoperitoneal shunt (VPS) surgery is the traditional method for treating hydrocephalus, remaining one of the most regularly used procedures in pediatric neurosurgery. The reported revision rate of VPS can reach up to 80% and significantly reduces the quality of life in the affected children and has a high socioeconomic burden. Traditionally, distal VPS placement has been achieved open via a small laparotomy. However, in adults several studies have shown a lower rate of distal dysfunction using laparoscopic insertion. As the data in children are scarce, the aim of this systematic review and meta-analysis was to compare open and laparoscopic VPS placement in children regarding complications.

METHODS

PubMed and Embase databases were searched using a systematic search strategy to identify studies comparing open and laparoscopic VPS placement up to July 2022. Two independent researchers assessed the studies for inclusion and quality. Primary outcome measure was distal revision rate. A fixed effects model was used if low heterogeneity (I2 < 50%) was present, otherwise a random effects model was applied.

RESULTS

Out of 115 screened studies we included 8 studies in our qualitative assessment and three of them in our quantitative meta-analysis. All studies were retrospective cohort studies with 590 analyzed children, of which 231 children (39.2%) received laparoscopic, and 359 children (60.8%) open shunt placement. Similar distal revision rates were observed between the laparoscopic and open group (3.75% vs. 4.3%, RR 1.16, [ 95% CI 0.48 to 2.79], I2 = 50%, z = 0.32, p = 0.74). There was no significant difference in postoperative infection rate between the two groups (laparoscopic 5.6% vs. open 7.5%, RR 0.99, (95% CI [0.53 to 1.85]), I2=0%, z = -0.03, p= 0.97). The meta-analysis showed a significantly shorter surgery time in the laparoscopic group (49.22 (±21.46) vs. 64.13 (±8.99) minutes, SMD-3.6, [95% CI -6.9 to -0.28], I2=99%m z= -2.12, p= 0.03) compared to open distal VPS placement.

CONCLUSION

Few studies are available comparing open and laparoscopic shunt placement in children. Our meta-analysis showed no difference in distal revision rate between laparoscopic and open shunt insertion; however, laparoscopic placement was associated with a significantly shorter surgery time. Further prospective trials are needed to assess possible superiority of one of the techniques.

Distal shunt placement in pediatric ventriculoperitoneal shunt surgery: an international survey of practice

OBJECTIVE

Ventriculoperitoneal shunt (VPS) surgery is a common treatment for hydrocephalus in children and adults, making it one of the most common procedures in neurosurgery. Children being treated with a VPS often require several revisions during their lifetime with a lifetime revision rate of up to 80%. Several different techniques exist for inserting the distal catheter, while mini-laparotomy, trocar, or laparoscopy is traditionally used. As opposed to adults, only few studies exist, comparing the outcome of the different distal catheter placement techniques in children. This international survey aims to investigate the current daily practice concerning distal shunt placement techniques in children.

MATERIAL AND METHODS

An online questionnaire investigating the different techniques used to place the distal catheter in pediatric VPS surgery was distributed internationally. All results were analyzed using descriptive and comparative statistics.

RESULTS

A total of 139 responses were obtained. Mini-laparotomy was reported to be the most frequently used technique (n = 104, 74.8%) for distal shunt placement in children, while laparoscopic or trocar-assisted placements were only used by 3.6% (n = 5) and 21.6% (n = 30) of all respondents, respectively. Over half (n = 75, 54.0%) of all respondents do not believe that laparoscopic placement improves the outcome.

CONCLUSION

This international survey shows that mini-laparotomy is the most frequently used technique for distal VPS placement in children all over the world. Further randomized trials are needed to elucidate this matter.

Incentive Nursing can Effectively Improve the ESCA Level of Patients with Endometrial Cancer after Laparoscopic Hysterectomy

Objective

To investigate the effect of incentive nursing on the rehabilitation of patients with endometrial cancer after laparoscopic hysterectomy.

Methods

A total of 110 patients with endometrial cancer receiving laparoscopic hysterectomy in our hospital from October 2017 to July 2020 were recruited and assigned at a ratio of 1 : 1 to receive either routine nursing (control group) or incentive nursing plus routine care (study group). Outcome measures included the self-rating anxiety scale (SAS) score, Hamilton depression scale (HAMD) score, the exercise of self-care agency (ESCA) score, postoperative rehabilitation outcomes, the incidence of nursing complications, and nursing satisfaction.

Results

Patients receiving incentive nursing showed significantly lower SAS scores and HAMD scores, and a higher ESCA score versus patients given routine care alone (P < 0.05). Incentive care resulted in a shorter length of hospital stay and postoperative time of out-of-bed activities and exercises versus routine care (P < 0.05). Incentive care was associated with a significantly lower incidence of nursing complications and higher nursing satisfaction versus routine nursing (P < 0.05).

Conclusion

Incentive nursing can effectively improve the ESCA level of patients, promote postoperative recovery, and reduce the incidence of complications, so it is worthy of clinical promotion.

Laparoscopic Co-surgeon Ventriculoperitoneal Shunt Placement Versus Single Surgeon Mini Laparotomy

Introduction: Ventriculoperitoneal (VP) shunt placement is one of the most common treatments for pediatric hydrocephalus. However, device failures often occur, requiring operative revision of either the intraventricular or intraperitoneal shunt catheters. Historically, shunt placement was performed via laparotomy, but there has been a trend towards laparoscopic-assisted placement of the intraperitoneal portion of the shunt. We examined the outcomes of laparoscopic-assisted versus open VP shunt placement utilizing a local institutional retrospective review.

Methods: Single institution 2012-2017 retrospective review of all cases was performed. Patients were divided into two groups - laparoscopic and open. Thirty-day outcomes, patient age, surgery performed, surgical control time (SCT), length of stay (LOS), and readmission were analyzed. 

Results: Cohort analysis inclusion criteria included 188 patients. The cohort analysis showed both decreased laparoscopic-assisted SCT (56.4 vs 32.1 min, p<0.0001) and postop complications (16.7% vs 7.1%, p<0.07). There was no significant difference in surgical site infection or readmission rates. 

Conclusion: Local analysis show advantages for laparoscopic-assisted VP shunt placement over open single surgeon techniques with decreased SCT, LOS, and unplanned interventions.

OS reboot

Cerebrospinal fluid (CSF) diversion or shunting procedures are the most commonly performed surgery for the treatment of hydrocephalus and are often employed in the management of elevated intracranial pressure due to a variety of diseases. Despite their popularity however, approximately 50% of shunts fail within the first two years, and several revisions are required within the first decade after placement. Ophthalmologists may encounter patients with a CSF shunt to evaluate for concerns of vision loss or diplopia and to determine if papilledema is present. We discuss the neuro-ophthalmic manifestations and evaluation of possible CSF shunt malfunction.

General surgery involvement with ventriculoperitoneal shunt insertions reduces revision rates

BACKGROUND

Ventriculoperitoneal shunts (VPS) are placed for a variety of etiologies. It is common for general surgery to assist with insertion of the distal portion in the peritoneum.

OBJECTIVE

To determine if there is a difference in revision rates in patients undergoing VPS placement with general surgery as well as those undergoing laparoscopic insertion.

METHODS

A retrospective review of all consecutive patients undergoing VPS placements was performed in a three-year period (2017-2019). Those that underwent placement with general surgery were compared to those without general surgery. Additionally, patients undergoing distal placement via mini-laparotomy versus laparoscopy were compared. Multivariable logistic regression was used to examine risk factors for distal VPS failure.

RESULTS

331 patients were included. 202 (61.0 %) underwent VPS placement with general surgery. 121 (36.6 %) patients underwent insertion via laparoscopic technique. General surgery involvement reduced operative times, decreased length of stay, and lowered overall revision rates with distal revision rates being most significant (1.5 % vs 8.5 %; p = 0.0034). Patients undergoing VPS placement via laparoscopic technique had decreased operative time, length of stay, in-hospital complications and revision rates, with significant decrease in shunt infection (1.7 % vs 7.1 %; p = 0.0366). A history of prior shunt or abdominal surgery (OR 3.826; p = 0.0282) and lack of general surgery involvement (OR 20.98; p = 0.0314) are independent risk factors for distal shunt revision in our cohort.

CONCLUSION

The use of general surgeons in VPS insertion can be of benefit by decreasing operative time, length of stay, total revisions, and distal revision rates. Further prospective studies are warranted to determine true benefit.
