Outcome After Laparoscopic Fundoplication in Children Under 1 Year

A systematic review on safety and surgical and anesthetic risks of elective abdominal laparoscopic surgery in infants to guide laparoscopic ovarian tissue harvest for fertility preservation for infants facing gonadotoxic treatment

Background

Infertility is an important late effect of childhood cancer treatment. Ovarian tissue cryopreservation (OTC) is established as a safe procedure to preserve gonadal tissue in (pre)pubertal girls with cancer at high risk for infertility. However, it is unclear whether elective laparoscopic OTC can also be performed safely in infants <1 year with cancer. This systematic review aims to evaluate the reported risks in infants undergoing elective laparoscopy regarding mortality, and/or critical events (including resuscitation, circulatory, respiratory, neurotoxic, other) during and shortly after surgery.

Methods

This systematic review followed the Preferred reporting Items for Systematic Review and Meta-Analyses (PRISMA) reporting guideline. A systematic literature search in the databases Pubmed and EMbase was performed and updated on February 15th, 2023. Search terms included 'infants', 'intubation', 'laparoscopy', 'mortality', 'critical events', 'comorbidities' and their synonyms. Papers published in English since 2000 and describing at least 50 patients under the age of 1 year undergoing laparoscopic surgery were included. Articles were excluded when the majority of patients had congenital abnormalities. Quality of the studies was assessed using the QUIPS risk of bias tool.

Results

The Pubmed and Embase databases yielded a total of 12,401 unique articles, which after screening on title and abstract resulted in 471 articles to be selected for full text screening. Ten articles met the inclusion criteria for this systematic review, which included 1778 infants <1 years undergoing elective laparoscopic surgery. Mortality occurred once (death not surgery-related), resuscitation in none and critical events in 53/1778 of the procedures.

Conclusion

The results from this review illustrate that morbidity and mortality in infants without extensive comorbidities during and just after elective laparoscopic procedures seem limited, indicating that the advantages of performing elective laparoscopic OTC for infants with cancer at high risk of gonadal damage may outweigh the anesthetic and surgical risks of laparoscopic surgery in this age group.

10 Year Follow-Up of Randomized Trial of Laparoscopic Nissen Versus Thal Fundoplication in Children

Introduction: The aim of this study was to compare the long-term outcomes of laparoscopic complete (Nissen) fundoplication (LNF) with laparoscopic partial (Thal) fundoplication (LTF) in children. This is the only prospective, randomized study to follow patients up for more than 10 years. Interim results published in 2011 at median 2.5 year follow-up showed that LNF had a significantly lower failure rate compared with LTF. Materials and Methods: A randomized, controlled trial of LNF versus LTF in children (<16 years) was performed. The primary outcome measure was "absolute" failure of the fundoplication-recurrence of symptoms that merited either reoperation or insertion of transgastric jejunostomy (GJ). Secondary outcomes were "relative" failure (need for postop antireflux medication), complications (e.g., dysphagia), and death. Results: One hundred seventy-five patients were recruited; 89 underwent LNF, and 86 underwent LTF. Eight patients had no follow-up recorded. At long-term follow-up, 59 patients had died (35%); LNF 37/85 (43.5%) and LTF 22/82 (26.8%), P = .02. Median length of follow-up in survivors was 132 months. There was no statistically significant difference in "absolute" failure rate between LNF 8/85(9.4%) and LTF 15/82 (18%), P = .14. There was no difference in "relative" failure between LNF 7/85 (8.2%) and LTF 12/82 (14%), P = .23. Long-term dysphagia affected 5 out of 108 (4.6%) patients; 3/48 (6.2%) of LNF and 2/60 (3.3%) of LTF (P = .65). Conclusions: There was no statistically significant difference in 'absolute' failure between LNF and LTF at long-term follow-up. Neurologically impaired children have a high mortality rate following fundoplication due to comorbidities. This trial commenced in 1998 and was approved by the Oxfordshire Research Ethics Committee (No. 04.OXA.18-1998).

Laparoscopic fundoplication after oesophageal atresia repair

BACKGROUND

Esophageal atresia (EA) is a rare congenital malformation. A high incidence of GER unresponsive to medical management is noted with EA. Literature suggests that complications from GER can persist in adulthood. In paediatric age, laparoscopic treatment is a valid option even if recurrence rate is not negligible.

AIMS AND OBJECTIVES

To evaluate our experience with gastro-esophageal reflux (GER) treatment after esophageal atresia (EA) repair.

MATERIALS AND METHODS

We retrospectively analysed 29 consecutive patients treated for EA at birth and studied for GER at our Institute in a period of 11 years.

RESULTS

24/29 (82,7%) cases had symptoms of reflux, 17/29 (58,6%) cases were treated with laparoscopic fundoplication (LF). Three infants were younger than 6 months and had apparent life threatening events (ALTE) condition as principal indication for surgery. No intra-operative complications occurred. 3/17 LF had open surgical conversion due to technical problems. 2/17 cases required a second operation. At the last follow-up: (1) 6/17 (35,3%) of patients healed after the last operation, (2) 8/17 (47,1%) have GER improvement (four still in medical treatment), (3) 2/17 (11,8%) have persistent GER, (4) 1/17 (5,9%) died for causes not related to antireflux surgery.

CONCLUSIONS

According to literature and to our retrospective analysis, LF for GER after EA repair is feasible, even if recurrence risk is not negligible. Infants less than 6 months old with associated conditions (malformations, gastrostomy/jejunostomy) seem to have a higher failure rate with a greater risk of conversion. Longer follow-up and multicenter experiences would guarantee an adequate surveillance for patients with EA.

Fluorescence-Guided Surgery (FGS) during a Laparoscopic Redo Nissen Fundoplication: The First Case in Children

We present the first case of fluorescence-guided surgery (FGS) using indocyanine green (ICG) in a pediatric redo-Nissen fundoplication. The patient is a 17-year-old male with recurrent gastroesophageal symptoms who underwent primary antireflux surgery at 10 months of age. During the redo fundoplication, ICG was intravenously administered to help the visualization during the adhesiolysis between liver, stomach and right crus of the diaphragm and to spare small oesophageal vessels and the left gastric artery. In this case, FGS made the surgery easier than usual and likely reduced the risk of intra-operative complications. Therefore, we believe that this new technology should be regularly used in these types of complex intra-abdominal redo operations.

Postfundoplication retching: Strategies for management

BACKGROUND

Retching is a common symptom in children following antireflux surgery, particularly in those with neurodisability. There is now a strong body of evidence that implicates retching as a major cause of wrap breakdown. Retching is not a symptom of gastroesophageal reflux disease; it is a component of the emetic reflex. In addition to causing wrap breakdown, it is indicative of the presence of nausea. It is a highly aversive experience and warrants treatment in its own right.

METHODS

A framework was constructed for the management of postoperative retching, with strategies targeting different components of the emetic reflex. The impact of differing antireflux procedures upon retching was also considered.

CONCLUSIONS

Once treatable underlying causes have been excluded, the approach includes modifications to feeds and feeding regimens, antiemetics and motility agents. Neuromodulation and other, novel, therapies may prove beneficial in future. Children at risk of postoperative retching may be identified before any antireflux surgery is performed. Fundoplication is inappropriate in these children because it does not treat their symptoms, which are not because of gastroesophageal reflux, and may make them worse. They are also at risk of wrap disruption. Alternative strategies for symptom management should be employed, and fundoplication should be avoided.

Predictors of multiple readmissions or death in the first year after Nissen fundoplication in children

PURPOSE

Nissen fundoplication (NF) is commonly performed in children with gastro-esophageal reflux disease (GERD). Patients undergoing NF often have co-morbidities. Reported outcomes of NF vary considerably. This study investigated which factors might predict multiple readmissions or death in the first year following NF at our institution.

METHODS

A retrospective chart review of 187 children who underwent NF at our institution between January 2004 and December 2015 was undertaken. Underlying medical conditions, age, weight, presence of malnutrition, length of hospital stay prior to surgery and type of surgery were recorded. Patients who had more than one admission in the first post-operative year were compared to those who had one or none, and patients who died within the first post-operative year were compared to those who did not.

RESULTS

Risk factors for multiple readmissions were underlying cardiac disease (p = 0.011), esophageal atresia (EA) (p = 0.011), and esophageal stricture (p = 0.0002). Risk factors for death included younger age (p = 0.028), need for gastrostomy tube (GT) (p = 0.01) and prolonged pre-operative hospital admission (p = 0.0003).

CONCLUSION

This study identified multiple factors associated with readmission and death in the first year after NF. These findings will help with the counseling patients and caregivers regarding expectations following NF.

Gastroesophageal reflux in children with neurological impairment: a systematic review and meta-analysis

Neurologically impaired children (NIC) suffer severe gastroesophageal reflux (GER) with poor fundoplication outcome. Aims of the study were: (1) to determine the recurrence of GER after fundoplication in NIC; (2) to compare fundoplication versus gastro-jejunal tube feeding insertion (GJ) and fundoplication versus total esophagogastric dissociation (TEGD) in primarily treating GER in NIC. Using defined search strategy, two investigators identified all comparative studies reporting the mentioned procedures to primarily treat GER in NIC. The study was conducted under PRISMA guidelines. The meta-analysis was performed using RevMan 5.3. Data are mean ± SD. Of 3840 titles/abstracts screened, 14 studies on fundoplication (2716 pts.) reported a recurrence/persistence of GER higher in NIC (14.2 ± 8.3%) than in neurologically normal (9.4 ± 5.2%; p = 0.0001), with an increased incidence of re-do fundoplication (12.6 ± 7.0% versus 9.1 ± 4.5%; p < 0.01). Three studies revealed a similar risk of undergoing subsequent fundoplication after GJ (4.9 ± 2.1%) or initial fundoplication (12.0 ± 0.6%; p = ns). Four studies showed a lower recurrence of GER following TEGD (1.4 ± 1.1%) than fundoplication (24.8 ± 1.4%; p = 0.002). NIC are at risk of recurrence/persistence of GER after fundoplication or GJ. TEGD seems more effective to primarily treat GER in NIC. Prospective randomized controlled trials are necessary to establish which is the ideal treatment of GER in NIC.

Outcomes of laparoscopic nissen fundoplications in children younger than 2-years: single institution experience

BACKGROUND

Variation exists in the diagnostic testing for gastroesophageal reflux (GER) in infants and in the application of surgical therapy. There has been an increase in antireflux surgery (ARS) since the development of laparoscopy but the outcomes in high-risk infants is unclear. This study examines the results of laparoscopic fundoplication in infants less than 2 years.

METHODS

The results of infants less than 2 years undergoing laparoscopic Nissen fundoplication (Lap-F) from 2012 to 2015 were retrospectively reviewed and outcomes were followed until 2017.

RESULTS

There were 106 patients, median gestational age 32.50 weeks ± 6.35 SD and non-corrected age at operation 23.0 weeks ± 19.0 SD, mean weight of 4.81 kg ± 2.10 SD. One of the most common reasons for surgical consultation was improvement in respiratory status after insertion of nasoduodenal feeding tube. Of the Lap-F, 100 were with gastrostomy tube (GT). There were no conversions to open or intraoperative complications. The complication rate was 4.71%, and the reoperation rate was 5.66%, one fundoplication revision and the others gastrostomy revisions. The median time for feeds and to reach goal were 1 (1-14) and 4 (2-279) days, respectively. The 30-day mortality was 0.9% and long-term it was 4.71%. The long-term mortality was related to the underlying medical problems. The median follow-up was 113 (3-286) weeks. One patient required revision of the fundoplication and none required esophageal dilatation during the follow-up period.

CONCLUSION

Fundoplication is effective for relief of symptoms of GER in children younger than 2 years. The procedure has a low morbidity and mortality in this population.

Long-term outcome of laparoscopic Nissen-Rossetti fundoplication versus Thal fundoplication in children with esophageal hiatal hernia: a retrospective report from two children's medical centers in Shanghai

BACKGROUND

This study was undertaken to investigate the intraoperative and postoperative complications, efficacy and outcome of two laparoscopic fundoplications for the treatment of esophageal hiatal hernia in children.

METHODS

To find a rational procedure, we performed a retrospective analysis of 136 children with esophageal hiatal hernia who underwent laparoscopic Nissen-Rossetti or Thal fundoplication at two children's hospitals in Shanghai over 13 years. The median follow-up time of the children was 42 months (range: 1-138 months). Their age varied from 1 month to 11 years (median: 18.6 months).

RESULTS

All the children underwent laparoscopic fundoplications (72 cases of Nissen-Rossetti and 60 cases of Thal fundoplication) and 4 children converted to open surgery. The mean age of the children at the time of operation was 1.6±1.9 years, and the mean weight was 9.1±5.6 kg. Gastroesophageal reflux was significantly more severe after a Thal fundoplication (P=0.003) and slight esophageal stenosis was significant after a Nissen-Rossetti fundoplication (P=0.02). The recurrent rate of hiatal hernia was 2.8% (2/72) after Nissen-Rossetti fundoplication in contrast to 5% (3/60) after Thal fundoplication. No death occurred after surgery.

CONCLUSION

There was no statistical difference of recurrence between laparoscopic Nissen-Rossetti and Thal fundoplication in the long-term outcomes. The rate of slight dysphagia was higher in the Nissen-Rossetti group. The Thal group had a significantly higher recurrence rate of gastroesophageal reflux. There still exited learning curve for this procedure. The incidence rate of complications is significantly related to the proficiency of pediatric surgeon.

Laparoscopic Toupet fundoplication for gastroesophageal reflux: a series of 131 neurologically impaired pediatric cases at a single children's hospital

PURPOSE

To present the medium to long-term outcome of the largest pediatric series of laparoscopic Toupet fundoplications (LTF) performed at a single institution.

PATIENTS AND METHODS

Subjects were 131 neurologically impaired children (81 M, 50 F) who underwent LTF between 2003 and 2013. Our LTF involves full dissection of the crus of the diaphragm to allow the intraabdominal esophagus to be mobilized at least 3-4 cm.

RESULTS

Preoperative mean fraction time for pH <4 was 14.6 %. Mean age at LTF was 6.7 years (3 months-18 years). Mean duration of follow-up was 5.7 years (range 1.2-12.1 years). One case required conversion to open surgery. Intra-operative complications were all injuries to the esophagus/gastric wall (n = 4; 3.0 %) including full-thickness perforation (n = 1; 0.8 %). Postoperative complications included pyloric stenosis (n = 4; 3.0 %), dysphagia (n = 1; 0.8 %), incisional hernia (n = 1; 0.8 %), hemorrhage requiring transfusion (n = 1; 0.8 %), recurrence (n = 3; 2.3 % at 11, 13, and 48 months, respectively), and gastrostomy site infection (n = 7; 5.3 %). Mean operative time decreased significantly with experience from 180.8 min for the first quarter of subjects to 150.6 (2nd quarter), 128.6 (3rd) and 109.2 min (4th).

CONCLUSIONS

Our LTF would appear to be safe for treating GERD in children because of reliable outcome and low recurrence.

Anti-gastroesophageal reflux surgery in infants with severe bronchopulmonary dysplasia

Gastroesophageal reflux may exacerbate lung disease in infants with bronchopulmonary dysplasia (BPD). Anti-reflux surgery may therefore reduce the severity of this disease in some infants. We report a retrospective series of 22 infants with severe BPD who underwent anti-reflux surgery. Our experience indicates that these procedures can be safely performed in this population and that early post-operative initiation of gastric feeds is well tolerated. Modest post-operative reductions in required oxygen and median respiratory rate were observed.

Laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease in infants

INTRODUCTION

Data on laparoscopic Nissen fundoplication for gastro-oesophageal reflux disease (GERD) in infants remain limited. We describe our experience with this operation in children and in particular, infants younger than 12 months old.

MATERIALS AND METHODS

Medical records of all paediatric patients who had laparoscopic fundoplication done for GERD from 1998 to 2013 were reviewed. Patients were divided into two groups based on age: group I: 0-12 months, and group II >12 months. Data on indications, patient's demographics, operative time, blood loss, conversions, complications, recurrences and duration of hospitalization were studied.

RESULTS

A total of 86 patients were reviewed (group I, n = 21; group II, n = 65). While the mean age and body weight for group I were 8 ± 2.99 months and 6 ± 1.96 kg, the values for group II were 98 ± 65 months and 18 ± 9.6 kg, respectively. All patients had concurrent laparoscopic gastrostomy for feeding difficulties. The mean operative time was shorter in group I (157 ± 55 vs 169 ± 52 min, p = 0.66). Both groups had minimal blood loss only. The surgical outcomes in both groups were comparable in terms of recurrence (0 vs 3 %, p = 0.105) and complications (9.5 vs 6 %, p = 0.275). The median follow-up duration for group I and group II was 23 and 40 months, respectively. Sixteen (76 %) patients in group I and 45 (67 %) patients in group II did not develop pneumonia post fundoplication.

CONCLUSION

Laparoscopic Nissen fundoplication can be safely performed in infants with outcomes comparable to older patients and a shorter operative duration. Low recurrence rate (up to 3 %) is shown by our long term follow-up data. We recommend laparoscopic Nissen fundoplication to be considered in managing infants with GERD.

Outcomes of pediatric laparoscopic fundoplication: a critical review of the literature

BACKGROUND/OBJECTIVE

Laparoscopic fundoplication for gastroesophageal reflux disease (GERD) is one of the most common procedures performed in children. A critical literature review was performed to evaluate the level and quality of evidence supporting the efficacy of this procedure.

METHODS

Systematic reviews of the EMBASE, PubMed and CENTRAL databases were conducted to retrieve all articles published over a 15-year period (1996 to 2010) reporting medium- to long-term outcomes (minimum six months follow-up) of laparoscopic fundoplication for the treatment of pediatric GERD. Articles were critically appraised using the Newcastle-Ottawa quality assessment scale and the Cochrane risk of bias assessment tool. Extracted outcomes included GERD recurrence, need for reoperation, postoperative morbidity and mortality.

RESULTS

A total of 5302 articles were retrieved. Thirty-six studies met inclusion and exclusion criteria, including five prospective (level 2b), four retrospective comparative (level 3b) and 27 case series (level 4). No studies compared laparoscopic fundoplication with medical treatment. Thirty-six per cent of studies did not describe the symptoms used to suspect GERD; 11% did not disclose the diagnostic modalities used; and 41% did not report the findings of diagnostic modalities. Only 17% of studies provided a definition of recurrence, and only 14% attempted to control for confounding variables. The follow-up intervals were inconsistently reported, ranging between two months and nine years. Significant heterogeneity among studies limited the ability to pool outcomes. Mean (± SD) recurrence rates varied between 0% and 48±19.6% of patients. Reoperation was required in 0.69±0.95% to 17.7±8.4% of patients. Mortality ranged between 0% and 24±16.7%.

CONCLUSION

The level and quality of the evidence supporting laparoscopic fundoplication are extremely poor. Higher-quality data are required before the procedure can be considered to be an effective intervention in the treatment of pediatric GERD.

A multicenter study of the incidence and factors associated with redo Nissen fundoplication in children

AIM

The objective of this study was to identify the incidence and factors associated with redo Nissen fundoplication in children.

METHODS

After Institutional Review Board approval (5100277), data for children under 18 years of age from two children's hospitals with fundoplication performed between January 1994 and December 2010 were reviewed. Children with one fundoplication were compared to those with redos to identify factors associated with redo. Variables were compared using t-tests for continuous and chi-square tests for categorical variables. Logistic regression evaluated for independence.

RESULTS

There were 823 patients and 54.7% were male. A redo fundoplication was required in 100 (12.2% of cohort); 82 had 1 redo, 14 had 2 redos, and 4 had 3 redos. Follow-up ranged from 0.01 to 16.9 years (median: 2.9 years). Factors associated with redo were: younger age at first fundoplication, (p=0.002), hiatal dissection (p<0.001), and male gender (p=0.008). Independent predictors of redo were: hiatal dissection at first fundoplication, OR: 8.45 (95% CI: 2.45-29.11), retching, OR: 3.59 (95% CI: 1.56-8.25) and younger age at first fundoplication, OR: 0.98 (95% CI: 0.97-0.98).

CONCLUSION

The incidence of redo fundoplication in children is 12.2%. The risk of redo is significantly increased if patients are younger, have retching, and if the esophageal hiatus is dissected at the first fundoplication.

Anti-reflux surgery for patients with esophageal atresia

Gastroesophageal reflux (GER) is almost constant in esophageal atresia and tracheoesophageal fistula (EA/TEF). These patients resist medical treatment and require antireflux surgery quite often. The present review examines why this happens, the long-term consequences of GER and the main indications and results of fundoplication in this particular group of patients. The esophagus of EA/TEF patients is malformed and has abnormal extrinsic and intrinsic innervation and, consequently, deficient sphincter function and dysmotility. These anomalies are permanent. Fifty percent of patients overall have GER, and one-fifth have Barrett's metaplasia. Close to 100%, GER of pure and long-gap cases require fundoplication. In the long run, these patients have 50-fold higher risk of carcinoma than the control population. GER in EA/TEF does not respond well to dietary, antacid, or prokinetic medication. Surgery is necessary in protracted anastomotic stenoses, in pure and long-gap cases, and when there is an associated duodenal atresia. It should be indicated as well in other symptomatic cases when conservative treatment fails. However, confection of a suitable wrap is anatomically difficult in this condition as shown by a failure rate of 30% that is also explained by the persistence for life of the conditions facilitating GER.

Thirty-day outcome in children randomized to open and laparoscopic Nissen fundoplication

BACKGROUND

Laparoscopic Nissen fundoplication (LNF) is considered by some to be superior to open Nissen fundoplication (ONF). To test this hypothesis, we compared early results after LNF and ONF in a randomized trial.

METHODS

All children accepted for antireflux surgery for gastroesophageal reflux disease were offered enrollment. Ethical approval and parental consent were obtained. Anesthesia, surgical methods, and postoperative treatment were standardized. Patient demographics, length of hospital stay (LOS), and complications occurring the first 30 postoperative days were registered.

RESULTS

Eighty-eight children were randomized to LNF (n = 44) or ONF (n = 44). The groups were comparable with regard to age, weight, and comorbidity. Duration of surgery was 150 ± 34 minutes for LNF and 89 ± 25 minutes for ONF (P < .001). Median LOS was 7.0 days (range, 3-57 days) and 7.5 days (range, 2-20 days) after LNF and ONF, respectively (P = .74). Postoperative complications occurred in 48 patients, 24 in both groups. Twenty-four patients (LNF: n = 12, ONF: n = 11) were readmitted to hospital because of complications occurring after discharge.

CONCLUSIONS

This study failed to show that LNF is superior to ONF when surgery duration, LOS, and complications occurring during the first postoperative month were compared. Apart from surgery duration, the results were surprisingly similar.

Current Controversies in the Surgical Treatment of Esophageal Atresia

Background and Aims:

Esophageal atresia (EA) with or without tracheo-esophageal fistula (TEF) is a rare condition that can be nowadays succesfully treated. The current interest therefore is focused on the management of the difficult cases, on thoracoscopic approach, and on some aspects of the long-term results.

Methods:

The current strategies for the difficult or impossible anastomoses in pure and long-gap EA, the introduction of thoracoscopic repair and the causes, mechanisms and management of post-operative gastro-esophageal reflux (GER) are reviewed.

Results:

Methods of esophageal elongation and multi-staged repair of pure and long-gap EA allow anastomosis but with functional results that are often poor. Esophageal replacement with colon or stomach achieves at least similar results and often requires less procedures. Thoracoscopic repair is a promising adjunct, but the difficulties for setting it as a gold-standard are pointed out. GER is a part of the disease and its surgical treatment, that is often required, is burdened by high failure rates.

Conclusions:

EA with or without TEF can be successfully treated in most cases, but a number of unsolved issues remain and the current approach to difficult cases will certainly evolve in the future.
