Comparing laparoscopic versus open Ladd's procedure in pediatric patients

A case of isolated malrotation without midgut volvulus diagnosed prenatally and treated by laparoscopic surgery

BACKGROUND

Malrotation is a congenital condition that predisposes individuals to midgut volvulus, which can result in significant bowel resection. While most cases of malrotation are diagnosed by the age of 1 year, typically presenting with symptoms related to volvulus or bowel obstruction, some cases remain asymptomatic. In children with visceral malposition, gastroschisis, omphalocele, or diaphragmatic hernia, malrotation may be suspected before symptoms manifest. However, isolated malrotation without midgut volvulus diagnosed prenatally is rare. We herein present a case of isolated malrotation without midgut volvulus that was prenatally diagnosed and successfully treated with laparoscopic surgery.

CASE PRESENTATION

A 30-year-old woman (gravida 3, para 1) underwent routine obstetric ultrasound, which revealed increased blood flow in the lower uterine segment and abnormal placental attachment. To rule out placenta percreta, magnetic resonance imaging was performed at 34 weeks of gestation. Incidentally, abnormal fetal intestinal arrangement was noted, with the colon localized in the left hemi-abdomen and the small intestine distributed in the right hemi-abdomen, raising suspicion of malrotation. Postnatal contrast studies confirmed the diagnosis of malrotation without midgut volvulus. Given the risk of midgut volvulus, a laparoscopic Ladd's procedure was performed on day 6 of life. The postoperative course was uneventful, and the patient was still symptom-free 1 year postoperatively.

CONCLUSIONS

This case illustrates that malrotation can be prenatally diagnosed using fetal magnetic resonance imaging. Considering the risk of midgut volvulus, prophylactic Ladd's procedure should be performed in neonatal period. In cases where malrotation is not complicated by midgut volvulus, a laparoscopic Ladd procedure can be safely performed in neonates.

Laparoscopic Versus Open Ladd Procedure for Midgut Malrotation

INTRODUCTION

Intestinal malrotation is an uncommon developmental anomaly that can lead to duodenal obstruction and midgut volvulus. The standard correctional operation, Ladd's operation, is traditionally performed using an open approach, but providers are increasingly performing the procedure laparoscopically. However, there remains concern that the reduced adhesive burden associated with laparoscopy could predispose to recurrent volvulus.

METHODS

We queried our institutional database from 2012 to 2022 for patients <18 years who underwent Ladd's operation for malrotation. We analyzed baseline characteristics and outcomes including post-operative volvulus, adhesive small bowel obstruction (SBO), duodenal obstruction, and overall abdominal re-operation.

RESULTS

We identified 226 patients, of whom 90 (40%) underwent a laparoscopic operation. Those undergoing open surgery were younger and had a higher rate of volvulus compared to laparoscopic patients. There were no differences in surgical history or underlying comorbidities. Laparoscopic patients were less likely to develop a post-operative adhesive SBO [1/90 (1%) vs 14/136 (10.0%); OR 9.4 (1.7-176.4), p = 0.036] with no increased rate of volvulus [1/90 (1%) vs 1/136 (0.7%), p = 0.778]. However, there were four laparoscopic patients that required re-operation for a duodenal stricture or kink, which led the overall rate of abdominal re-operation to not be different [7/90 (8%) vs 16/136 (12%); OR 1.6 (0.6-4.8), p = 0.371]. Median follow up was 2.3 years [IQR 1.0-5.0].

CONCLUSION

Laparoscopic correction of midgut malrotation demonstrates no increased risk of post-operative volvulus and may reduce the rate of adhesive SBO. These benefits must be weighed against the potential increased risk of duodenal stricture or obstruction secondary to an incomplete Ladd's procedure.

Identification and treatment of intestinal malrotation with midgut volvulus in childhood: a multicenter retrospective study

Background

Intestinal malrotation is a rare condition, and its delayed diagnosis can lead to fatal consequences. This study aimed to investigate the identification and treatment of malrotation in children.

Methods

Clinical data, imaging, operative findings, and early postoperative outcomes of 75 children with malrotation were retrospectively analyzed.

Results

The mean age was 6.18 ± 4.93 days and 51.26 ± 70.13 months in the neonatal group (56 patients) and non-neonatal group (19 patients), respectively. Sixty-seven patients were under the age of 1 year at the time of diagnosis. The occurrence of bilious vomiting and jaundice was significantly higher in the neonatal group (89.29%) than that in the non-neonatal group (37.5%), p < 0.05 and p < 0.01, respectively. The incidence of abnormal ultrasound (US) findings was 97.30% and 100%, respectively, and the sensitivities of the upper gastrointestinal series were 84.21% and 87.5%, respectively. Sixty-six (88%) patients had midgut volvulus, including in utero volvulus (two patients) and irreversible intestinal ischemia (four patients). Most neonates (89.29%) underwent open Ladd's procedure with a shorter operative time (p < 0.01). Reoperation was performed for postoperative complications (four patients) or missed comorbidities (two patients).

Conclusions

Non-bilious vomiting was the initial symptom in >10% of neonates and nearly 40% of non-neonates. This highlights the importance for emergency physicians and surgeons to be cautious about ruling out malrotation in patients with non-bilious vomiting. Utilizing US can obviate the need for contrast examinations owing to its higher diagnostic accuracy and rapid diagnosis and can be recommended as a first-line imaging technique. Additionally, open surgery is still an option for neonatal patients.

Laparoscopic Ladd's procedure for intestinal malrotation in small infants with midterm follow-up

BACKGROUND

The objective of this study was to evaluate the safety and efficacy of laparoscopic Ladd's procedure (LL) for intestinal malrotation (IM) in small infants.

METHODS

All patients aged < 6 months with IM who underwent Ladd's procedures between January 2012 and December 2019 were enrolled. The perioperative demographics and midterm follow-up results were retrospectively reviewed and compared between patients who underwent LL and open Ladd's operation (OL).

RESULTS

Fifty-five patients were enrolled for analysis. The baseline characteristics were well matched in the two groups. The rate of volvulus was similar in the two groups (76.2% vs. 73.5%, P = 0.81). Two cases in the LL group were converted to OL due to intraoperative bleeding and intestinal swelling. The operative time (ORT) was not significantly different between the two groups (73.8 ± 18.7 vs. 66.8 ± 11.6 min, P = 0.76). Compared to the OL group, the LL group had a shorter time full feed (TFF) (3.1 ± 1.2 vs. 7.3 ± 1.9 days, P = 0.03) and a shorter postoperative hospital stay (PHS) than the OL group (5.5 ± 1.6 vs. 11.3 ± 2.7 days, P = 0.02). The rate of postoperative complications was similar in the two groups (9.5% vs. 11.8%, P = 0.47). The LL group had a lower rate of adhesive obstruction than the OL group, but the difference was not significant (0.0% vs. 11.8%, P = 0.09). One patient suffered recurrence in the LL group, while 0 patients suffered recurrence in the OL group (4.8% vs. 0.0%, P = 0.07). The rate of reoperation in the two groups was similar (4.8% vs. 8.8%).

CONCLUSIONS

The LL procedure for IM in small infants was a safe and reliable method that had a satisfactory cosmetic appearance and shorter TFF and PHS than OL.

Perioperative outcomes in minimally-invasive versus open surgery in infants undergoing repair of congenital anomalies

BACKGROUND

This study compared perioperative outcomes among infants undergoing repair of congenital anomalies using minimally invasive (MIS) versus open surgical approaches.

METHODS

The ACS NSQIP Pediatric (2013-2018) was queried for patients undergoing repair of any of the following 9 congenital anomalies: congenital lung lesion (LL), mediastinal mass (MM), congenital malrotation (CM), anorectal malformation (ARM), Hirschsprung disease (HD), congenital diaphragmatic hernia (CDH), tracheoesophageal fistula (TEF), hepatobiliary anomalies (HB), and intestinal atresia (IA). Inverse probability of treatment weights (IPTW) derived from propensity scores were utilized to estimate risk-adjusted association between surgical approach and 30-day outcomes.

RESULTS

12,871 patients undergoing congenital anomaly repair were included (10,343 open; 2528 MIS). After IPTW, MIS was associated with longer operative time (difference; 95% CI) (16 min; 9-23) and anesthesia time (13 min; 6-21), but less postoperative ventilation days (-1.0 days; -1.4- -0.6) and shorter postoperative length of stay (-1.4 days; -2.4- -0.3). MIS repairs had decreased risk of any surgical complication (risk difference: -6.6%; -9.2- -4.0), including hematologic complications (-7.3%; -8.9- -5.8). There was no significant difference in risk of complication when hematologic complications were excluded (RD -2.3% [-4.7%, 0.1%]). There were no significant differences in the risk of unplanned reoperation (0.4%; -1.5-2.2) or unplanned readmission (0.2%; -1.2-1.5).

CONCLUSIONS

MIS repair of congenital anomalies is associated with improved perioperative outcomes when compared to open. Additional studies are needed to compare long-term functional and disease-specific outcomes.

MINI-ABSTRACT

In this propensity-weighted multi-institutional analysis of nine congenital anomalies, minimally invasive surgical repair was associated with improved 30-day outcomes when compared to open surgical repair.

Diagnosis and management of intestinal rotational abnormalities with or without volvulus in the pediatric population

Intestinal malrotation is a congenital anomaly that can be associated with midgut volvulus, requiring an emergent operation in order to maintain blood supply to the compromised intestine. It results from an abnormal rotation of the intestines, leading to three types of malrotation. Non-rotation is complete failure of the intestines to rotate, while the most common configuration is associated with the cecum in the mid-upper abdomen, close to a malpositioned duodenal-jejunal (DJ) flexure. This configuration has a narrow mesentery that has a high risk of volvulus. The final form of malrotation is incomplete rotation, where the DJ flexure and cecum are malpositioned, but the mesentery is not narrowed. The benefits of performing a Ladd's procedure for these individuals is controversial. Workup for malrotation should be considered in all patients who present with abdominal pain/distention and bilious emesis. An upper gastrointestinal contrast study is 93-100% sensitive and will show a corkscrew appearance when a volvulus is present. While the basic tenets of the Ladd's procedure have not changed and include detorsion of a volvulus, adhesiolysis of Ladd's bands and broadening of the mesentery, how this is accomplished and in whom are controversial. Laparoscopic Ladd's is associated with shorter hospital stays but also has a higher incidence of recurrent volvulus compared to an open approach. Patients with heterotaxy syndrome also represent a controversial group with some studies showing no difference in post-operative complications despite a higher mortality due to underlying cardiac disease, while other studies show a low incidence of volvulus and question the need for Ladd's in those who are asymptomatic. This review highlights the major aspects of diagnosing and treating malrotation, including the pathophysiology, workup, surgical options and areas of controversy.

Laparoscopic versus Open Pediatric Surgery: Three Decades of Comparative Studies

INTRODUCTION

 Despite its wide acceptance, the superiority of laparoscopic versus open pediatric surgery has remained controversial. There is still a call for well-founded evidence. We reviewed the literature on studies published in the last three decades and dealing with advantages and disadvantages of laparoscopy compared to open surgery.

MATERIALS AND METHODS

 Studies comparing laparoscopic versus open abdominal procedures in children were searched in PubMed/MEDLINE. Reports on upper and lower gastrointestinal as hepatobiliary surgery and on surgery of pancreas and spleen were included. Advantages and disadvantages of laparoscopic surgery were analyzed for different types of procedures. Complications were categorized using the Clavien-Dindo classification.

RESULTS

 A total of 239 studies dealing with 19 types of procedures and outcomes in 929,157 patients were analyzed. We identified 26 randomized controlled trials (10.8%) and 213 comparative studies (89.2%). The most frequently reported advantage of laparoscopy was shorter hospital stay in 60.4% of studies. Longer operative time was the most frequently reported disadvantage of laparoscopy in 52.7% of studies. Clavien-Dindo grade I to III complications (mild-moderate) were less frequently identified in laparoscopic compared to open procedures (80.3% of studies). Grade-IV complications (severe) were less frequently reported after laparoscopic versus open appendectomy for perforated appendicitis and more frequently after laparoscopic Kasai's portoenterostomy. We identified a decreased frequency of reporting on advantages after laparoscopy and increased reporting on disadvantages for all surgery types over the decades.

CONCLUSION

 Laparoscopic compared with open pediatric surgery seems to be beneficial in most types of procedures. The number of randomized controlled trials (RCTs) remains limited. However, the number of reports on disadvantages increased during the past decades.

Outcomes for Ladd's procedure: Does approach matter?

BACKGROUND

Laparoscopic Ladd's procedure has been proven safe and effective for the treatment of malrotation. However, the nationwide utilization and outcomes of elective Ladd's procedure are largely unknown.

METHODS

The Nationwide Readmissions Database from 2010 to 2014 was used to identify patients 0-18 years (excluding newborns) with malrotation who underwent elective Ladd's procedure. Demographics, hospital factors, and outcomes were compared by approach (laparoscopic vs. open) using standard statistical tests and propensity score (PS) matched analysis. Results were weighted for national estimates.

RESULTS

1343 patients (44% male) underwent elective Ladd's procedure via laparoscopic (22%) or open (78%) approach. Laparoscopic approach was more common in large hospitals (26% vs. 16%), patients >13 years (30% vs. 20%), and those with higher income (29% vs. 16%), all p < 0.001. Following PS matching, compared to the laparoscopic approach, open Ladd's was associated with index hospital length of stay > 7 days (20% vs. 8%), more post-operative gastrointestinal dysfunction (12% vs. < 1%), and more nausea, vomiting, and/or diarrhea (16% vs. 6%), all p < 0.001. The overall readmission rates within 30 days and the year of index operation were 8% and 15%, respectively. In the matched cohort, those undergoing laparoscopic Ladd's were less likely to be readmitted than those with the open approach (7% vs. 16%, p < 0.001) and experienced less gastrointestinal issues on readmission (5% vs. 15%, p = 0.002). There were similar rates of post-operative small bowel obstruction (< 3% vs. < 3%, p = 0.840) and volvulus (0% vs. < 1%, p = 0.136). Redo Ladd's procedure was performed in less than 4% of readmissions and all occurred within 5 days of initial hospital discharge.

CONCLUSION

The majority of Ladd's procedures in the U.S. are being performed open, despite comparable outcomes following a laparoscopic approach. Readmission rates are similar with either approach, and the rate of redo Ladd's procedure is lower than previously reported.

Laparoscopic Versus Open Ladd's Procedure for Intestinal Malrotation in Infants and Children: A Systematic Review and Meta-Analysis

Aim: To compare clinical outcomes in infants and children with intestinal malrotation who were treated by laparoscopic or open Ladd's. Methods: PubMed, EMBASE, and Cochrane library were searched for studies comparing laparoscopy with open Ladd's for intestinal volvulus through January 5, 2021. Search terms were confined to Title/Abstract: "Intestinal Volvulus" OR "Intestinal malrotation" AND "Laparoscopy" AND "Laparotomy." Randomized controlled trials (RCTs) and retrospective studies comparing laparoscopy with open Ladd's in neonates, infants, or children were included. Outcomes evaluated included operative time, time to full feeds, length of hospital stay, rate of conversion, reoperation, overall postoperative complications, postoperative adhesive small bowel obstruction, and postoperative volvulus. Pooled odds ratios (OR) were calculated for dichotomous variables; pooled mean differences (MDs) were measured for continuous variables. Results: Fourteen studies were included, comprising 444 patients who underwent laparoscopic approach and 1422 patients who underwent open procedure. Laparoscopy group had shorter operative time (MD = -14.44 minutes, 95% confidence interval [CI] = -20.79 to -8.09, P < .00001), hospital stay (MD = -4.57 days, 95% CI = -7.58 to -1.56, P = .003), and time to full feeds (MD = -3.00 days, 95% CI = -3.80 to -2.19, P < .00001). Laparoscopic Ladd's procedure had less overall postoperative complications (OR = 0.35, 95% CI = 0.19-0.65, P = .0009), less postoperative adhesive small bowl obstruction (OR = 0.37, 95% CI = 0.19-0.74, P = .005), and more postoperative volvulus (OR = 2.97, 95% CI = 1.23-7.13, P = .02). There was no difference in incidence of reoperation rate (OR = 2.04, 95% CI = 0.96-4.33, P = .06). Conclusion: Laparoscopic procedure is superior to open Ladd's in operative time, hospital stay, time to full feeds, overall postoperative complication, and postoperative adhesive small bowel obstruction. However, more RCTs with adequate follow-up are needed to overcome the limitations of our study.

Outcomes of Laparoscopic Versus Open Ladd Procedures and Risk Factors for Conversion

Background: Malrotation is a common congenital anomaly that can lead to bowel obstruction and ischemia if not corrected with a Ladd procedure. Controversy exists between open and laparoscopic approaches. We sought to compare postoperative outcomes and determine risk factors for conversion to an open procedure. Methods: The National Surgical Quality Improvement Program (NSQIP)-Pediatric was used to identify patients undergoing Ladd procedures from 2013 to 2018. Propensity score matching was used to account for differences in patient characteristics between open and laparoscopically treated cohorts. Chi-square tests and adjusted logistic regression analysis were used to determine patient outcomes differences between treatment groups and factors associated with conversion. Results: A total of 2437 patients were identified, 1889 (77.5%) open, 548 (22.5%) laparoscopic, and 193 (35.2%) laparoscopic converted to open. Patients undergoing laparoscopic compared with open procedures had shorter length of stay (5 versus 7 days, P < .001) and lower overall complication rates (13.1% versus 18.1%, P = .025), despite longer operative times (108.9 versus 93.7 minutes, P < .001). Patients requiring conversion were more likely to be younger, have an urgent/emergent case, sepsis/septic shock, and nutritional support requirement. Conclusions: After risk adjustment, laparoscopic Ladd procedure is associated with decreased complications and minimal operative time increases compared with an open approach. Risk factors associated with conversion should be considered during operative planning.

Outcomes of laparoscopic and open surgical treatment of intestinal malrotation in children

BACKGROUND

The safety of the laparoscopic treatment of intestinal malrotation remains controversial. This study compared the outcomes of laparoscopic and open surgical treatment of intestinal malrotation.

METHODS

A multicentric retrospective study included pediatric cases of intestinal malrotation operated on between 2005 and 2016.

RESULTS

This study included 227 children with a median age of 17 days (0-17.2 years), including 161 with a midgut volvulus. Forty-six(20.3%) procedures were started by laparoscopy and 181(79.7%) by laparotomy. Laparoscopy was more frequent for elective surgery (45.9%) than for emergency procedures (10.8%, p < 0.001). Conversions were significantly more frequent during emergency procedures (66.7% vs 17.9%)(p = 0.001). Considering only 61 elective surgeries, the mean hospital stay was significantly shorter after laparoscopy (5.3 days +/-5.2 vs 10.1 days +/-13, p = 0.01), the overall complication rate was comparable (15.8% vs 21.7%, p = 0.7) but post-operative volvulus was significantly more frequent after laparoscopy (13% vs 0%, p = 0.04). Outcomes of the two approaches were not significantly different after 166 emergency procedures.

CONCLUSION

Laparoscopy can be performed by experienced team for the treatment of selected cases of intestinal malrotation. Conversion to open surgery should be done with a low threshold, as the rate of volvulus recurrence is concerning.

Laparoscopic Ladd Procedure for Malrotation in Newborns and Infants

BACKGROUND

Laparoscopic approach for malrotation has become more popular for neonates and in cases with volvulus, but its safety and efficacy remains controversial. This study reviewed laparoscopy outcomes in neonate/infant malrotation.

METHODS

Medline/PubMed and Lilacs databases were reviewed. Data from studies published in English/Spanish between 1995 and 2019 were collected. Results are presented as percentages and means/medians; logistic regression was used to study possible associations.

RESULTS

Nineteen papers offered 99 neonates/infants with median age and weight of 10.5 days and 3.5 kg, respectively. Ladd's procedure was performed in 95 (96%) patients and bands' division in 4 (4%); appendectomy was not included in 16 (16.2%) patients, and cecopexy was not performed in all cases. Volvulus was reported in 39 (39.4%) patients. There were 11 conversions (11.1%) and 10 recurrences of symptoms (10.1%) that required reintervention. An association was found between volvulus and recurrence (P = .05) and the need for conversion (P < .01). There were 10 (10.1%) minor complications and no mortality. The median follow-up was 10 months.

DISCUSSION

Laparoscopic approach to malrotation is feasible and safe in hemodynamically stable neonates/infants without intestinal necrosis and is associated with 11% conversion rate and 10% reinterventions. The presence of volvulus is associated with recurrence and conversion. Laparoscopic Ladd's procedure with appendectomy and without cecopexy is the commonly practiced approach that is associated with minor complications.

Laparoscopic Ladd's procedure in neonates: A simple landmark detorsion technique

BACKGROUND

The aim of this study was to assess the efficacy of our simple landmark technique for laparoscopic detorsion and the Ladd's procedure (lap-Ladd) for malrotation with midgut volvulus in neonates and to identify the risk factors for reoperation after the lap-Ladd.

METHODS

We conducted a retrospective chart review of 42 patients after lap-Ladd for malrotation between April 2017 and June 2019. Information regarding patient status and intraoperative and postoperative data were analyzed.

RESULTS

Thirty-one patients had volvulus (73.8 %), while 11 patients did not (26.2%). The median age and weight between the two groups at operation were 9 days (range, 3-28 days), 3.2 kg (range, 2-8 kg) and 6 days (range, 2-11), 2.9 kg (range, 2-3.8 kg), respectively. The operative time was significantly shorter in patients with volvulus compared to those without (60 vs 105 min, P = 0.002). Two cases were converted to open surgery because of ischemic changes of the total small intestine during surgery. Reoperation was required in two patients with volvulus (due to adhesive small bowel obstruction and recurrent volvulus). There was no significant predictive factor for reoperation after the lap-Ladd procedure.

CONCLUSION

Our simple landmark lap-Ladd procedure demonstrated feasibility and good short-term outcomes in neonates with malrotation, regardless of the presence or absence of volvulus.

Laparoscopic Ladd Procedure for the Management of Malrotation and Volvulus

Introduction: While laparoscopic Ladd procedure is commonly performed in patients with asymptomatic malrotation, a paucity of data exists on children with volvulus or with low weight (≤3 kg). Our purpose was to evaluate the safety and efficacy of the laparoscopic Ladd procedure in these complex patient populations. Methods: A retrospective review of patients undergoing operation for malrotation from 2008 to 2018 was performed. Specific subgroup analysis was performed comparing outcomes after open and laparoscopic approaches in patients presenting with acute volvulus or in low-weight (<3 kg) patients. Results: Out of 110 patients, 38 (35%) presented with volvulus and 72 (65%) without volvulus. In patients with volvulus, 16 (42%) underwent laparoscopy and 22 (58%) had an open procedure. More patients in the open group had a preoperative diagnosis of volvulus (63.6% vs. 12.5%, P = .002). Operative time was longer in the laparoscopic group (87 vs. 61 minutes, P = .029), with 7 patients being converted to an open procedure (44%). Days to regular diet, hospital length of stay, and recurrent volvulus were similar between groups. In patients weighting <3 kg, 10 patients underwent laparoscopy and 10 patients had an open procedure. Demographics, operative time, postoperative outcomes, and complications were similar between groups. One person in the laparoscopic group was converted to open. Conclusion: Laparoscopic management of malrotation, even in the presence of volvulus and low patient weight, is safe and effective, with low rates of recurrent volvulus. If exposure is suboptimal, conversion to open in patients with volvulus should be considered.

Laparoscopic Ladd's procedure for malrotation in infants and children is still a controversial approach

BACKGROUND

Open Ladd's procedure is the gold standard for the correction of intestinal malrotation and laparoscopic approach remains controversial. This study aimed to evaluate our experience in laparoscopic management of malrotation.

METHODS

Single center retrospective study including patients who underwent a laparoscopic assessment of intestinal malrotation with correction if appropriate between 2007 and 2017.

RESULTS

Sixty-five patients (median age 7 months) had a laparoscopic assessment with and without correction of malrotation. Forty-five (69%) were symptomatic, including 16 (25%) with a midgut volvulus. The procedure was completed laparoscopically in 55 (86%) patients in 110 min (30-190). Conversions happened more frequently at the beginning of the experience. With a follow-up of 12.5 months (8 days-5.3 years), morbidity rate was 15% and 4 (6%) patients underwent a redo surgery, all in the first 5 months after surgery, compared with 3/53 (6%) in a contemporaneous group undergoing open Ladd's.

CONCLUSION

This is the largest series reported so far of the laparoscopic management of malrotation. Laparoscopic Ladd's procedure is reliable but still exposes to open conversion which may be in part owing to a learning curve. A low conversion threshold is important in cases with volvulus. The redo rate is similar to that of the open procedure.

Postoperative Small Bowel Obstruction Following Laparoscopic or Open Fundoplication in Children: A Retrospective Analysis Using a Nationwide Database

BACKGROUND

Postoperative small bowel obstruction (SBO) is one of the most serious adverse events resulting in deteriorated quality of life in children. Numerous studies have shown that laparoscopic surgery significantly reduces the occurrence of SBO compared with open surgery in adults. However, evidence of the advantages of laparoscopic surgery over open surgery in terms of reducing SBO is lacking in children. Fundoplication is a common abdominal procedure in children. This study was performed to compare the occurrence of SBO after laparoscopic fundoplication (LF) versus open fundoplication (OF).

METHODS

Using the Diagnosis Procedure Combination database, a national inpatient database in Japan, we retrospectively identified patients aged 0-18 years who underwent LF or OF from July 2010 to March 2016. Propensity score adjustment was used to compare the occurrence of SBO between the groups.

RESULTS

We identified 1838 eligible patients who underwent LF (n = 1362) or OF (n = 476). The median age at surgery was 4.0 and 1.5 years in the LF and OF group, respectively (P < 0.001). The median weight at admission was 11.4 and 7.5 kg, respectively (P < 0.001). Nineteen (1.4%) patients in the LF group and 13 (2.7%) in the OF group had at least one episode of SBO (P = 0.11, log-rank test). In the propensity score-adjusted Cox regression analysis, SBO was significantly less likely to occur in the LF than OF group (hazard ratio, 0.36; 95% confidence interval 0.16-0.82; P = 0.01).

CONCLUSIONS

In this retrospective nationwide study, LF was significantly associated with a reduction in SBO compared with OF in children.

Reoperation after Ladd's procedure in the neonatal period

AIM OF THE STUDY

To investigate (1) the indications for reoperation after neonatal Ladd's procedure, (2) the type of reoperation and (3) its outcome.

METHODS

We reviewed all neonatal Ladd's procedures in our hospital from 2003 to 2017 and the outcomes of reoperation in these patients.

MAIN RESULTS

252 neonates had Ladd's procedure: 59 were laparoscopic (23.4%) and 193 open (76.6%). 15 (6.0%) required reoperation with no difference between laparoscopic and open (p = 0.12). Overall, the indications for reoperation were: adhesive intestinal obstruction (n = 10, 4.0%), recurrent midgut volvulus (n = 4, 1.6%), and missed diagnosis of associated anomaly (n = 1, 0.4%). The incidence of recurrent midgut volvulus was higher after laparoscopic Ladd's procedure (3/59; 5.1%) compared to open Ladd's procedure (1/193; 0.5%) (p = 0.04). Adhesive intestinal obstruction developed after both open (8/193, 4.1%) or laparoscopic Ladd's procedure (2/59, 3.3%). The duration of reoperation and the length of post-operative hospital stay were 63.4 ± 27.1 min and 10.1 ± 5.2 days, respectively. After reoperation, there were no post-operative complications. All children were well at follow-up (6 months-14 years).

CONCLUSIONS

In neonates, laparoscopic Ladd's procedure compared to the open Ladd's procedure is associated with a significantly higher risk of recurrent volvulus. The risk of developing this potentially dangerous complication after laparoscopic Ladd's procedure raises doubts about the effectiveness and safety of the laparoscopic approach in neonates.

Is less more? Laparoscopic versus open Ladd's procedure in children with malrotation

BACKGROUND

With the advent of minimally invasive techniques, laparoscopic Ladd's procedure is increasingly used to treat children with malrotation, yet evidence regarding its safety and efficacy is lacking. We hypothesize that operative and postoperative outcomes with the open technique are superior to the laparoscopic Ladd's procedure.

METHODS

We conducted a 5-y retrospective chart review of all patients who underwent Ladd's procedure at our institution from 2010-2015. Exclusion of patients included those with concomitant conditions, such as poor gut perfusion, significant reflux, tracheoesophageal fistula, failure to thrive requiring concomitant gastrostomy, and biliary atresia. Kruskal-Wallis and Mann-Whitney tests were used where appropriate.

RESULTS

Between 2010 and 2015, of 130 patients who underwent Ladd's procedure, 77 met inclusion criteria. Sixty-two patients underwent initial open surgery, 15 patients underwent laparoscopy, seven of which were converted to open. Patients undergoing open surgery were younger compared to the laparoscopic groups. Thirty-three of the 77 malrotation patients (43%) presented with volvulus, 27 underwent open surgery, four had laparoscopic converted to open procedures, and two patients underwent laparoscopic Ladd's without incident. Laparoscopy resulted in increased operative time and clinic visits. Patients undergoing laparoscopic to open surgery had longer operative times, time to resume diet, and length of hospital stay. No difference was noted in complications among the groups.

CONCLUSIONS

Although minimally invasive approaches are becoming increasingly used, no evidence supports laparoscopic superiority over open Ladd's procedure. We found that open surgery was associated with shorter operating times and fewer clinic visits. Furthermore, laparotomy remains the favored procedure for patients presenting with volvulus.
