Laparoscopic fundoplication in children with previous abdominal surgery

Laparoscopic Fundoplication in Patients with Ventriculoperitoneal Shunts: A Systematic Review and Our Experience

Background: Data on the outcomes of laparoscopic fundoplication (LF) in patients with ventriculoperitoneal (VP) shunts are limited. Materials and Methods: We retrospectively evaluated the demographic characteristics and outcomes of patients who underwent LF at our institutions between 2014 and 2022. Then, we systematically reviewed articles in MEDILINE/PubMed, Cochrane Library, and Web of Science. Results: There was no significant difference in terms of the outcomes between patients with VP shunt (n = 10) and those without (n = 96) at our institutions. None of the patients presented with shunt trouble after LF. The meta-analysis included four retrospective studies and our institutional data. In total, 605 patients (55 with VP shunt) underwent LF. Furthermore, 2 (3.6%) of 55 patients (1 with infection and 1 with occlusion) had shunt troubles. The conversion and complication rates, operative time, and length of hospital stay did not significantly differ between patients with VP shunt and those without. Conclusions: LF can be safely performed on children with VP shunts and is associated with a low risk of shunt troubles. The Clinical Trial Registration number is 2022-387.

To assess the safety of laparoscopy in patients with CSF catheters draining distally into the abdomen

PURPOSE

This study evaluates the safety of laparoscopic procedures in patients with cerebrospinal fluid (CSF) catheters draining distally into the abdomen.

METHODS

A systematic search across PubMed, Scopus, and Ovid databases using pertinent keywords yielded 47 relevant papers, encompassing 197 cases, for analysis.

RESULTS

In the pediatric cohort (n = 129), male (49.6%) and female (34.1%) cases were reported, while gender remained unspecified in 16.3%. Shunt indications included unspecified (126 cases) and Meningomyelocele (3 cases). Laparoscopic procedures encompassed gastric (72.1%), urologic (21.7%), and other (6.2%) indications. Peri-operative shunt management included subcostal incision and clamping (1), ICP monitoring and drainage (2), and distal shunt flow confirmation (1). The prevalent complication was mechanical obstruction (10.1%), followed by pseudocyst formation (1.5%) and infection (2.3%). In the adult cohort (n = 61), males (60.6%) and females (39.3%) with a median age of 55 years were observed. Management strategies encompassed sponge packing and mobilization (11), distal shunt flow confirmation (2), shunt clamping (3), Transcranial Doppler monitoring (2), and no manipulation (30). Shunt infection emerged as the primary complication (2). Overall, 24 patients encountered VP shunt-related complications post-laparoscopy.

CONCLUSION

This study underscores the safety of laparoscopic interventions in patients with ventriculoperitoneal or lumboperitoneal shunts when facilitated by interdisciplinary cooperation. A meticulous preoperative assessment for shunt track localization, intraoperative visualization of shunt tip with CSF flow, vigilant perioperative anesthetic monitoring, and shunt dysfunction surveillance are crucial for favorable outcomes in laparoscopic procedures for these patients.

How many tests does it take? Minimizing preoperative testing prior to surgical placement of gastrostomy tubes in children

BACKGROUND

Gastrostomy tubes (GTs) provide life-saving enteral access for children. Although upper gastrointestinal (UGI) series and impedance studies (ISs) detect gastroesophageal reflux disease (GERD) or malrotation, their benefit for preoperative evaluation of asymptomatic patients requiring GT placement is controversial. This study investigated the value of routine preoperative testing and whether specific patient characteristics could guide the selective use of these studies.

METHODS

The charts of children who underwent GT placement from 2003 to 2019 were reviewed retrospectively. Demographics, preoperative evaluation, and postoperative course were evaluated.

RESULTS

Three hundred forty-three patients underwent GT placement, 61% with preoperative testing. Seven of 190 UGI (4%) series demonstrated malrotation, and 39 of 141 (28%) ISs revealed severe GERD. Although all malrotations were surgically addressed, only 59% (23/39) of IS-proven GERD cases prompted simultaneous fundoplication. Age <1 year was associated with a positive UGI series (6.7% positive vs 1.0%; P < 0.05), but no other patient characteristics were associated with either positive UGI series or IS. Elimination of the 96% of UGI series that did not alter care represented a cost savings of $89,487-$229,665 and avoided the radiation exposure from testing; elimination of the 84% of ISs that did not alter eventual treatment would have saved $127,776-$266,563.

CONCLUSION

Routine preoperative evaluation with UGI series and IS can increase healthcare costs without substantially altering care. The only patients potentially benefiting from routine UGI series were <1 year old. Instead, a targeted, symptom-based preoperative evaluation may streamline the process by decreasing preoperative testing and minimizing cost and radiation exposure.

Impact of previous abdominal surgery on the outcome of fundoplication for medically refractory gastroesophageal reflux disease in children and young adults

Importance

Fundoplication (FP) is a well-established surgical treatment for gastroesophageal reflux disease (GERD) refractory to medical therapy in children and young adults. During FP, previous abdominal surgery (PAS) can impair the patient’s outcome by causing technical difficulties and increasing intra- and postoperative complication rates.

Objective

The aim of this study was to determine the impact of PAS on the short- and long-term outcome following FP for refractory GERD in a cohort of patients aged < 23 years.

Methods

We retrospectively analyzed 182 patients undergoing a total of 201 FP procedures performed at our university center for pediatric surgery from February 1999 to October 2019. Pre-, intra-, and postoperative variables were recorded and their impact on the rate of intraoperative complications and revision FP (reFP) was analyzed.

Results

A total of 201 FP procedures were performed on 182 patients: 119 (59.2%) as Thal-FP (180° anterior wrap) and 82 (40.8%) as Nissen-FP (360°circular wrap; 67.2% laparoscopic, 32.8% open, 8.9% conversion). The presence of PAS (95 cases, 47.3%) was associated with significantly longer operative times for FP (153.4 ± 53.7 vs.126.1 ± 56.4 min, p = 0.001) and significantly longer hospital stays (10.0 ± 7.0 vs. 7.0 ± 4.0 days, p < 0.001), while the rates of intraoperative surgical complications (1.1% vs. 1.9%, p = 1.000) and the rate re-FP in the long term (8.4% vs. 15.1%, p = 0.19) during a follow-up period of 53.4 ± 44.5 months were comparable to the group without PAS.

Conclusion

In cases of PAS in children and young adults, FP for refractory GERD might necessitate longer operative times and longer hospital stays but can be performed with surgery-related short- and long-term complication rates comparable to cases without PAS.

Laparoscopic fundoplication in children with ventriculo-peritoneal shunts

BACKGROUND

Children with ventriculo-peritoneal (V-P) shunts have a significant risk of morbidity and mortality from infections. Many of these patients have other co-morbidities and may require subsequent abdominal surgery, including fundoplication with or without gastrostomy placement. The aim of our study was to assess the outcomes of laparoscopic fundoplication in children with a V-P shunt in situ.

SUBJECTS AND METHODS

A retrospective review of a prospectively maintained database on children who underwent laparoscopic fundoplication with a V-P shunt in situ at the time of surgery between July 1998 and March 2011 was conducted. Primary outcomes included intra- and postoperative complications as well as shunt-related problems within a 6-month period after surgery. The subset of children with V-P shunts was compared with those who underwent fundoplication without shunts. Variables were compared using the two-tailed Student's t test, chi-squared test, or Fisher's exact test. Significance was defined as P≤.05.

RESULTS

Out of a total of 343 children who underwent fundoplication, 11 (6 girls, 5 boys) had a V-P shunt in situ at the time of surgery (3.2%). The median age at laparoscopy was 2.2 years (range, 0.7-13.8 years). Weight at surgery ranged from 5.8 to 39.0 kg (median, 12.0 kg). The operating time (without gastrostomy placement) was 105 minutes (range, 80-140 minutes). In 6 patients (55%) moderate to severe adhesions were documented, but only 1 child required conversion to open surgery because of bleeding from the omentum. In a second patient the colon was perforated during insertion of the percutaneous endoscopic gastrostomy (PEG) and repaired laparoscopically. There was no postoperative shunt dysfunction or infection related to the laparoscopic procedure. There was no significant difference between V-P shunt patients and the main cohort regarding operating time, conversion to open surgery, need for admission to a high-care unit, opiate requirements, time to full feeds, and length of hospital stay.

CONCLUSIONS

These data suggest that laparoscopic fundoplication is feasible in children with previous V-P shunt placement. Although there were considerable adhesions in approximately half of these patients, the rate for conversion to open surgery was low. Complications associated with simultaneous PEG insertion occur and should be anticipated by placing the gastrostomy under laparoscopic guidance.

The safety of laparoscopy in pediatric patients with ventriculoperitoneal shunts

INTRODUCTION

In pediatric patients requiring abdominal operations, ventriculoperitoneal (VP) shunts for hydrocephalus are a frequently encountered comorbidity. Laparoscopy has not been extensively evaluated in this population, and there are concerns about the safety of insufflation under pressure with the shunt in place. There are a paucity of data in the literature to address this issue. Further, there is a relative lack of long-term follow-up in the literature to document shunt function over time after abdominal procedures. Therefore, we reviewed our experience in patients with VP shunts who underwent either open or laparoscopic abdominal procedures to determine the safety of laparoscopy in these patients.

METHODS

We conducted a retrospective review of all pediatric patients with VP shunts who underwent laparoscopic and/or open abdominal operations at a single institution from 1998 to 2008. Complications were defined as a shunt- or surgery-related event (including any shunt revisions) within 6 months of abdominal surgery. Continuous variables were compared by using an independent sampled, two-tailed Student's t-test. Discrete variables were analyzed with Fisher's exact test with Yates correction, where appropriate. Significance was defined as P < or = 0.05.

RESULTS

A total of 99 intra-abdominal operations were performed on patients with VP shunts: 51 were laparoscopic and 48 were open. Mean age was 3.17 versus 2.93 years, respectively (P = 0.77). The most common procedure performed in both groups was fundoplication with gastrostomy. There were no episodes of air embolism into the shunt. There was 1 shunt infection in the laparoscopic group and 3 in the open group (P = 0.56).

CONCLUSIONS

Our data suggest that laparoscopy is safe in patients with ventriculoperitoneal shunts.

Laparoscopic fundoplication after previous open abdominal operations in infants and children

BACKGROUND

There have been multiple reports in the adult literature stating that previous open operations should no longer be considered a contraindication to the laparoscopic approach. However, there are little data on this topic in the pediatric population, particularly in patients with neonatal abdominal pathology unique to the newborn population. Therefore, we reviewed our experience with laparoscopic fundoplication after a variety of previous abdominal conditions and operations in the pediatric population.

METHODS

An institutional review board-approved retrospective chart review was performed on all patients undergoing laparoscopic fundoplication after a previous open operation between October 2000 and December 2007. The data collected demographics, comorbid conditions, previous abdominal operations, gastrostomy tube placement, time interval between the initial operation and laparoscopic fundoplication, conversions, and complications.

RESULTS

Forty-five patients underwent a laparoscopic Nissen fundoplication after an open operation during the study interval. Mean age was 41.3 months (range, 1-233) with a mean weight of 14.3 kg (range, 2.9-63.6), and 31 were (78.9%) male. A total of 61 previous abdominal operations were performed (range, 1-4). Mean time between last open operation and laparoscopic fundoplication was 27.3 months (range, 0.5-147). Mean operative time was 161 minutes (range, 73-420). There were no conversions and 3 perioperative complications occurred (splenic hematoma, clogged gastrostomy tube, and liver bleed). Early reoperations were performed in 2 patients (4.4%): 1 for bleeding on day 2 and the other for leaking gastrostomy day 12.

CONCLUSION

Our data demonstrate that laparoscopic fundoplication after a previous open operation is feasible and safe.

Hand-assisted Laparoscopic Total Proctocolectomy and Ileal Pouch-Anal Anastomosis After Liver Transplant for Primary Sclerosing Cholangitis

Chronic ulcerative colitis (CUC) is associated with extraintestinal manifestations such as primary sclerosing cholangitis (PSC). The onset of PSC can precede the diagnosis of CUC, and require liver transplantation in some patients. Surgical management of CUC posttransplant has traditionally been open total proctocolectomy and ileal pouch-anal anastomosis. Herein, we present a case of a woman with a previous liver transplant for PSC who subsequently developed CUC with dysplasia, successfully treated with hand-assisted laparoscopic total proctocolectomy and ileal pouch-anal anastomosis. Hand-assisted laparoscopic surgery is an excellent option for patients with previous complex abdominal surgery. It can be performed safely and expediently, providing the benefits of reduced hospital stay and early return of bowel function.

Endoscopic gastrostomy placement in the child with gastroesophageal reflux: is concomitant antireflux surgery indicated?

BACKGROUND/PURPOSE

Previously, we performed concomitant antireflux surgery in patients with abnormal pH study undergoing gastrostomy. This increased complications without always alleviating the troublesome symptom of vomiting. In contrast, vomiting with normal preoperative pH study generally disappeared after gastrostomy placement. Therefore, we changed policy to perform only gastrostomy, regardless of pH study results. Subsequent antireflux surgery is performed only as necessary. We report here our results.

METHODS

We retrospectively reviewed patients undergoing gastrostomy from April 1997 to January 2004. For patients with abnormal preoperative pH studies, detailed data were recorded including medical history, indication for gastrostomy, operative technique, symptoms of gastroesophageal reflux (GER), and use of antireflux medication. Symptomatic GER postgastrostomy was managed pharmacotherapeutically. If this proved inadequate, patients underwent antireflux surgery.

RESULTS

Twenty-eight patients with abnormal pregastrostomy pH study entered the study. Median age was 3 years and 2 months. Seventy-five percent were neurologically impaired. Indication for gastrostomy was inadequate oral nutrition in 26 of 28 patients. Only 3 of 28 patients were asymptomatic for GER. Of the 25 symptomatic patients 19 improved postgastrostomy (6 did not). Antireflux surgery ultimately proved indicated in 2 patients (7% [2/28]). The asymptomatic patients remained asymptomatic.

CONCLUSIONS

For patients with abnormal pH study presenting primarily for gastrostomy placement, concomitant antireflux surgery is not indicated.

Laparoscopic Nissen fundoplication without division of short gastric vessels in children

PURPOSE

It has been suggested that routine division of short gastric vessels (SGVs) results in a more "floppy" Nissen fundoplication leading to improved outcomes, that is, less dysphagia and lower incidences of recurrent gastroesophageal reflux disease (GERD). The aim of this retrospective study was to assess whether laparoscopic Nissen fundoplication without division of SGVs (Rossetti modification) (laparoscopic Nissen-Rossetti fundoplication [LNRF]) is associated with acceptable clinical outcome in children.

METHOD

The charts of 368 children who underwent LNRF between January 1996 and September 2004 by 1 primary surgeon were retrospectively reviewed. Children were divided into 2 groups: LNRF + gastrostomy (A) and LNRF alone (B). Mean follow-up period of all groups was 4.2 years.

RESULTS

Laparoscopic Nissen-Rossetti fundoplication was completed in 99% (365/368). Mean operating time for group A was 74 minutes and 61 minutes for group B. None in group A required postoperative esophageal dilatation, and 9 in group B (22.5%) required 12 dilatations; 3.6% developed recurrent GERD, 3.7% in group A and 2.5% in group B.

CONCLUSION

Laparoscopic Nissen-Rossetti fundoplication can be performed with acceptable long-term outcome in children, especially in the majority also requiring chronic gastrostomy access. Short-term, reversible dysphagia may be seen in a small percentage of children having fundoplication alone.

Laparoscopic fundoplication in children with a preexisting gastrostomy

BACKGROUND

Children with a gastrostomy may require laparoscopic fundoplication (LF).

METHODS

Children with a gastrostomy who underwent LF between 1998 and 2002 were reviewed. The outcomes of children undergoing LF were compared with a group of children without a gastrostomy who had the same operation during the same period.

RESULTS

Ten children with a gastrostomy in place and eight children without a gastrostomy underwent LF. The median operating time was 198 minutes (range, 115-300 minutes) in the gastrostomy group and 110 minutes (range, 80-130 minutes) in the non-gastrostomy group (P =.002). In the gastrostomy group, two children had ventriculoperitoneal shunts and two had extensive intra-abdominal adhesions due to peritonitis. One laparoscopic procedure in each group was converted to an open approach. A successful LF was performed in nine of the ten children without taking down the gastrostomy. One child with a gastrostomy experienced recurrent vomiting that was managed with a gastrojejunal tube. One child in the non-gastrostomy group required reoperation due to an esophageal stricture.

CONCLUSION

It seems that LF can be performed safely and effectively in children with a preexisting gastrostomy. LF in children with a gastrostomy seems to be as efficacious as LF in children without a gastrostomy.

Laparoscopic surgery for gastroesophageal reflux disease during the first year of life

BACKGROUND

Very few children need gastroesophageal antireflux surgery during their first year of life; hence, no series has been published so far. The authors report their experience in 3 centers.

METHODS

From January 1993 to December 1998, 36 infants between 23 days and 13 months of age, suffering from gastroesophageal reflux disease (GERD), underwent surgery by a laparoscopic approach. The patients' weights ranged from 2.4 to 8.5 kg. Preoperative diagnostic studies included esophagograms, manometries, endoscopies, and pH-metries. Fifteen babies (41.6%) had associated anomalies, and 10 (27.7%) were neurologically impaired. Thirty-six laparoscopic fundoplications were performed according to either Toupet's procedure (17 of 36), Rossetti's (10 of 36), Nissen's (8 of 36) or Lortat-Jacob's (1 of 36). Four infants previously had undergone a gastrostomy, whereas 6 needed one during the antireflux procedure.

RESULTS

There was no mortality in our series. Three infants (8.3%) had an intraoperative complication: 1 lesion of a diaphragmatic vessel, 1 pneumothorax, and 1 case of severe hiatal hernia requiring conversion to open surgery. During the median follow-up of 22 months, 4 redo procedures were performed (11.1%).

CONCLUSIONS

This experience shows the feasibility of laparoscopic fundoplication even in children below 1 year of age. An accurate preoperative diagnostic study is mandatory, because 50% of these patients presented associated anomalies. A long and accurate follow-up is necessary to evaluate long-term results and detect possible complications, which can occur as late as 1 year after surgery. In addition, we believe that redo antireflux surgery is possible by the laparoscopic approach without major difficulties, based on our larger experience with older children.
