Multicenter Comparison of Laparoscopic Versus Open Repair of Duodenal Atresia in Neonates

Laparoscopic Versus Conventional Open Congenital Duodenal Obstruction Repair: A Systematic Review and Meta-analysis

BACKGROUND

We conducted a systematic review and meta-analysis to evaluate the safety and effectiveness of laparoscopic surgery (LS) compared to open surgery (OS) for congenital duodenal obstruction (CDO).

METHODS

We conducted a literature review to find studies comparing LS and OS in neonates with CDO. A meta-analysis was conducted to systematically compile and compare factors, including surgical duration, time of feeding initiation, hospital length of stay (LOS), and postoperative complications.

RESULTS

Eleven studies with 1615 patients (LS: 338, OS: 1277) met inclusion criteria. Operative time was observed to be much shorter in the OS group (I2 = 97%); weighted mean difference (WMD) 60.29; 95% confidence interval (CI): 30.29 to 90.28; p < 0.0001). The LS group had a significantly shorter time to initiate feeding (I2 = 0%; WMD -3.38, 95% CI: -4.35 to -2.41; p < 0.00001), shorter time to full feeding (I2 = 0%; WMD -3.64, 95% CI: -5.06 to -2.22; p < 0.00001), and shorter LOS (I2 = 52%; WMD -3.42, 95% CI: -5.75 to -1.08; p = 0.004). There were no significantly differences in the rates of anastomotic leak (I2 = 24%; OR 0.76, 95% CI: 0.12 to 4.67; p = 0.76), anastomotic stricture (I2 = 0%; OR 1.12, 95% CI: 0.39 to 3.20; p = 0.83), postoperative ileus (I2 = 0%; OR 0.60, 95% CI: 0.21 to 1.74; p = 0.34), and overall complications between the groups (I2 = 59%; OR 0.86, 95% CI: 0.42 to 1.74; p = 0.68). The LS group, however, had a significantly decreased frequency of wound infection (I2 = 0%; OR 0.26, 95% CI: 0.08 to 0.82; p = 0.02).

CONCLUSION

Despite certain limitations in our analysis, the laparoscopic approach was associated with comparable postoperative outcomes.

Laparoscopic repair of duodenal atresia: systematic review and meta-analysis after consistent implementation of the technique in the past decade

BACKGROUND

Laparoscopic repair of duodenal atresia (LRDA) remains a technically challenging procedure and its benefits ambiguous. To assess the safety and efficacy of LRDA, we performed a systematic review of techniques and material for LRDA and a meta-analysis comparing outcomes with open repair (OR).

METHODS

Comprehensive search of EMBASSE, PubMed and Cochrane was performed from 2000 to 2023. Studies comparing LRDA with OR were identified and outcomes extracted included operative time, time to enteral feeds, length of hospitalisation, anastomotic leaks and stricture and total complications. χ2 was used to assess associations between complications and conversions rates of different LRDA approaches (laparoscopic technique, suturing technique). Comprehensive meta-analysis was used for Meta-analysis.

RESULTS

Twelve studies were identified and 1731 patients were enrolled in the study (398 [LRDA] and 1325 [OR]). Total rate of complications and conversion for LRDA was 15.58% and 18.84%, respectively. Complication rates were not significantly affected by operative technique and suturing technique. Conversion rates were not significantly affected operative technique; using a combination of interrupted and running suturing was significantly higher than using running or interrupted (χ2 = 7.45, p < 0.05). Anastomotic leaks, strictures and total complications were equivocal between LRDA and OR (OR 1.672, 95% CI 0.796-3.514; OR 2.010, 95% CI 0.758-5.333; OR 1.172, 95% CI 0.195-7.03). Operative time was significantly greater for LRDA (SDM 1.035, 95% CI 0.574-1.495, p < 0.001). Time to initial and full enteral feeds and length of hospitalisation were shorter in the LRDA group (SDM - 0.493, 95% CI - 2.166 to 1.752, p = 0.466; SDM - 0.207, 95% CI - 1.807 to 0.822, p = 0.019; SDM - 0.111, 95% CI - 1.101 to 0.880, p = 0.466, respectively).

CONCLUSIONS

LRDA showed equivalent complication rates compared to OR with an additional benefit of quicker establishment of feeds. There was no significant difference in complication and conversion rates between laparoscopic techniques. Despite a longer operative time, LRDA provides a safe minimal access approach for neonates after this consistent implementation of the technique in the past decade.

Duodenal Atresia Repair: A Single-Center Comparative Study

BACKGROUND

The use of laparoscopy in the repair of duodenal atresia has been increasing. However, there is no consensus regarding which surgical approach has better outcomes. We aimed to compare the different surgical approaches and types of anastomoses for duodenal atresia repair.

METHODS

Patients who underwent duodenal atresia repair at a single pediatric center were identified between January 2006 and June 2022. Those with concomitant gastrointestinal anomalies or who required other simultaneous operations were excluded. The primary outcome was rate of complications, defined as rate of leak, stricture, and re-operation by surgical approach and technique of anastomosis.

RESULTS

A total of 78 patients were included. The majority were female (51.3%, n = 40), with a median age of 4 days (IQR 3.0,8.0) and a median weight of 2.7 kg (IQR 2.2,3.3) at repair. The re-operation rate was 7.7% (n = 6), of which two were anastomotic leaks, and four were anastomotic strictures. The leak rate was 5.6% (n = 1/18) for the open handsewn and 4.8% (n = 1/21) for the laparoscopic handsewn technique. The stricture rate was 12.5% (n = 1/8) for the laparoscopic-assisted handsewn, 9.1% (n = 2/22) for the laparoscopic U-clip, 4.8% (n = 1/21) for the laparoscopic handsewn, and none with laparoscopic stapled and laparoscopic converted to open handsewn techniques. No differences were found in complication rate when controlling for surgical approach.

CONCLUSION

The method of surgical approach did not affect the outcomes or complications in the repair of duodenal atresia.

Avoiding Surgery: Endoscopic Treatment of Congenital Duodenal Stenosis

Duodenal stenosis is a rare congenital anomaly that is typically treated surgically, although endoscopic incisional therapy (EIT) and balloon dilation are minimally invasive alternatives. We present a case of a 15-month-old male with vomiting and difficulty tolerating solid food due to severe congenital duodenal stenosis. The patient underwent EIT and serial duodenal dilation to a diameter of 20 mm, which resulted in significant symptom improvement. Intralesional corticosteroid injection (ISI) was administered to help prevent the duodenal septum from restricturing. The combination of EIT, balloon dilation, and ISI was successful in treating the patient's congenital duodenal stenosis and avoided the need for surgery. However, further studies are required to confirm the efficacy of this treatment approach in this patient population. This report highlights the potential of this minimally invasive approach as an alternative to surgical intervention in the management of congenital duodenal stenosis.

Cardiac anomalies in children with congenital duodenal obstruction: a systematic review with meta-analysis

BACKGROUND

Cardiac anomalies occur frequently in patients with congenital duodenal obstruction (DO). However, the exact occurrence and the type of associated anomalies remain unknown. Therefore, the aim of this systematic review is to aggregate the available literatures on cardiac anomalies in patients with DO.

METHODS

In July 2022, a search was performed in PubMed and Embase.com. Studies describing cardiac anomalies in patients with congenital DO were considered eligible. Primary outcome was the pooled percentage of cardiac anomalies in patients with DO. Secondary outcomes were the pooled percentages of the types of cardiac anomalies, type of DO, and trisomy 21. A meta-analysis was performed to pool the reported data.

RESULTS

In total, 99 publications met our eligibility data, representing 6725 patients. The pooled percentage of cardiac anomalies was 29% (95% CI 0.26-0.32). The most common cardiac anomalies were persistent foramen ovale 35% (95% CI 0.20-0.54), ventricular septal defect 33% (95% CI 0.24-0.43), and atrial septal defect 33% (95% CI 0.26-0.41). The most prevalent type of obstruction was type 3 (complete atresias), with a pooled percentage of 54% (95% CI 0.48-0.60). The pooled percentage of Trisomy 21 in patients with DO was 28% (95% CI 0.26-0.31).

CONCLUSION

This review shows cardiac anomalies are found in one-third of the patients with DO regardless of the presence of trisomy 21. Therefore, we recommend that patients with DO should receive preoperative cardiac screening.

Laparoscopic versus open repair of congenital duodenal obstruction: a systematic review and meta-analysis

PURPOSE

To assess the safety and efficacy of laparoscopic versus open repair of congenital duodenal obstruction (CDO), we conducted a systematic review and meta-analysis (CDO).

METHODS

A literature search was conducted to identify studies that compared laparoscopic surgery (LS) and open surgery (OS) for neonates with CDO. Meta-analysis was used to pool and compare variables such as operative time, time to feeding, length of hospital stay, anastomotic leak or stricture, postoperative ileus, wound infection, and overall postoperative complications.

RESULTS

Among the 1348 neonatal participants with CDO in the ten studies, 304 received LS and 1044 received OS. When compared to the OS approach, the LS approach resulted in shorter hospital stays, faster time to initial and full feeding, longer operative time, and less wound infection. However, no significant difference in secondary outcomes such as anastomotic leak or stricture, postoperative ileus, and overall postoperative complications was found between LS and OS.

CONCLUSIONS

LS is a safe, feasible and effective surgical procedure for neonatal CDO when compared to OS. Compared with OS, LS has a faster time to feeding, a shorter hospital stay, and less wound infection. Furthermore, in terms of anastomotic leak or stricture, postoperative ileus, and overall postoperative complications, LS is equivalent to OS. We conclude that LS should be considered an acceptable option for CDO.

Laparoscopic Versus Open Surgical Repair of Duodenal Atresia: An NSQIP-Pediatric Analysis

INTRODUCTION

Laparoscopic repair of duodenal atresia in neonates has gained popularity among some pediatric surgeons. Single-center studies suggest comparable short-term outcomes to open surgery. The purpose of this study was to utilize a large, multi-institutional pediatric dataset to examine 30-day post-operative outcomes by operative approach for newborns who underwent duodenal atresia repairs.

METHODS

We identified neonates aged ≤1 wk in the 2016-2018 National Surgical Quality Improvement Program-Pediatric -database that underwent a laparoscopic or open repair for duodenal atresia. Preoperative characteristics were compared between operative approaches. Postoperative complications, operative time, postoperative length of stay (LOS), and supplemental nutrition at discharge were assessed using multivariate regressions.

RESULTS

There were 267 neonates who met inclusion criteria. There were 233 (87%) infants who underwent open repairs and 34 (13%) who underwent laparoscopic repairs. Ten (29%) children who had laparoscopy were converted to open. After adjusting for confounding, laparoscopy was associated with an increase in operative time by 65 min (95% confidence interval 45-87 min, P < 0.001) but a five-day shorter LOS (95% confidence interval -9 to -2, P = 0.006) when compared to laparotomy. There were no significant differences in postoperative complications or supplemental nutrition at discharge.

CONCLUSIONS

Our findings suggest that laparoscopic repairs of duodenal atresia are associated with shorter postoperative LOS but longer operative times when compared to open repairs. Although the conversion rate to laparotomy remained relatively high, the laparoscopic approach was associated with comparable 30-day postoperative outcomes.
