Meta-Analysis
CONTEXT
Despite the advantages of ultrasound (US), upper gastrointestinal contrast series (UGI) remains the first-line diagnostic modality in the diagnosis of midgut malrotation and volvulus in children.
OBJECTIVE
Evaluate the diagnostic accuracy of US in the diagnosis of malrotation with or without volvulus in children and adolescents aged 0-21 years, compared with the reference standard (diagnosis by surgery, UGI, CT, MRI, and clinical follow-up individually or as a composite).
DATA SOURCES
We searched the electronic databases Ovid-MEDLINE, Embase, Scopus, CINAHL, and the Cochrane library in October 2019 and updated on 18 August 2020.
STUDY SELECTION
Studies evaluating the diagnostic performance of US for diagnosis of midgut malrotation with or without volvulus in children (0-21 years).
DATA EXTRACTION AND SYNTHESIS
The data were extracted independently by two authors and a bivariate model was used for synthesis.
RESULTS
Meta-analysis of 17 cohort or cross-sectional studies and 2257 participants estimated a summary sensitivity of 94% (95% CI 89% to 97%) and summary specificity of 100% (95% CI 97% to 100%) (moderate certainty evidence) for the use of US for the diagnosis of malrotation with or without midgut volvulus compared with the reference standard. Subgroup analysis and meta-regression revealed better diagnostic accuracy in malrotation not complicated by volvulus, in the neonatal population and enteric fluid administration before US.
CONCLUSIONS
Moderate certainty evidence suggests excellent diagnostic accuracy and coupled with the advantages, a strong case exists for the use of abdominal US as the first-line diagnostic test for suspected midgut malrotation with or without volvulus in children and adolescents.

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 ( = .05) and the need for conversion ( < .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.

INTRODUCTION
Colonic volvulus is defined as a torsion of a part of the colon causing large bowel obstruction by strangulation which may lead to ischemia and then necrosis. The synchronous occurrence of a sigmoid colon and transverse colon volvulus is exceptional. We describe a case of synchronous sigmoid and transverse volvulus in a patient with a qualitative systematic review of this condition.
PRESENTATION OF THE CASE
This is a 74-year-old patient with a history of chronic constipation, who consulted for bowel obstruction. Plain abdominal radiography showed diffuse gas distension of the colon with the absence of rectal gas. An exploratory laparotomy was performed and showed sigmoid colon volvulus associated with synchronous transverse colon volvulus without bowel necrosis. A left hemicolectomy with loop colostomy was performed. The restoration of bowel continuity was done 3 weeks. The post-operative course was uneventful.
DISCUSSION
The occurrence of a simultaneous sigmoid and transverse colonic volvulus is an exceptional situation. Due to the rarity of this clinical entity, the literature concerning its description is sparse and the treatment options are poorly codified. There are no guidelines in the treatment and a tailored approach should be used for each patient.
CONCLUSION
The dual location of strangulation makes this situation a major surgical emergency with a high risk of gangrene and septic shock. Colectomy with delayed anastomosis should be preferred in the treatment.

INTRODUCTION
The aim of this systematic review was to appraise the current literature on the use of percutaneous endoscopic colostomy (PEC) as an alternative to major surgery and endoscopic decompression alone for treating sigmoid volvulus in frail, comorbid patients.
METHODS
A systematic literature search of literature published between April 2000 and January 2017 was carried out using the MEDLINE, Embase™ and CINAHL (Cumulative Index to Nursing and Allied Health Literature) databases. The search terms were "percutaneous endoscopic colostomy", "PEC", "sigmoidopexy", "sigmoidostomy" and "sigmoid volvulus". The studies identified were screened and those that did not fulfil the inclusion criteria were excluded.
FINDINGS
Seven observational studies and seven case reports (comprising eighty-one patients) were found to match our inclusion criteria. All patients had recurrent sigmoid volvulus and were treated with PEC either with a single PEC tube or with two PEC tubes inserted. Sigmoid volvulus recurred in 10 of the 81 patients; 3 of these individuals developed recurrence with PEC tubes in situ and 7 following tube removal. There were seven deaths after the procedure. The most frequent morbidity associated with PEC tube insertion was site infection (=6).
CONCLUSIONS
Our systematic review highlights the use of PEC as an alternative in managing recurrent sigmoid volvulus in frail, comorbid patients unfit for or refusing surgery, with the best outcomes seen in those patients where two PEC tubes were inserted and remained in situ indefinitely. Further studies are needed to improve the safety and efficacy of the procedure as well as post-procedure care.

Meta-Analysis
To compare clinical outcomes in infants and children with intestinal malrotation who were treated by laparoscopic or open Ladd's. 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. 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, < .00001), hospital stay (MD = -4.57 days, 95% CI = -7.58 to -1.56, = .003), and time to full feeds (MD = -3.00 days, 95% CI = -3.80 to -2.19, < .00001). Laparoscopic Ladd's procedure had less overall postoperative complications (OR = 0.35, 95% CI = 0.19-0.65, = .0009), less postoperative adhesive small bowl obstruction (OR = 0.37, 95% CI = 0.19-0.74, = .005), and more postoperative volvulus (OR = 2.97, 95% CI = 1.23-7.13, = .02). There was no difference in incidence of reoperation rate (OR = 2.04, 95% CI = 0.96-4.33, = .06). 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.

Review
BACKGROUND
Small bowel obstruction (SBO) is a common general surgical presentation and there has been a shift towards non-operative management (NOM) for patients with previous abdominal surgery. Historically, exploratory surgery has been mandated for SBO in patients with a virgin abdomen. However, there is increasing evidence for NOM in this group of patients.
METHODS
A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A search was undertaken between 1995 and 2020 on Ovid MEDLINE, EMBASE and PubMed. Primary outcome measures were success and failure rates, whereas secondary outcome measures were morbidity, mortality rates and identifying underlying aetiologies.
RESULTS
Six observational studies were included, with 205 patients in the NOM and 211 patients in the operative group. There was a high success rate of 95.6% and low morbidity rate of 3.1% in the NOM group compared to 88.6% and 26% in the operative group, respectively. Both groups reported no mortalities. The most common aetiologies for SBO in a virgin abdomen were adhesions (63%), malignancy (11%), foreign body/bezoar (5%), internal hernia (4%) and volvulus (4%).
CONCLUSION
NOM for SBO is a safe and feasible option for a select group of clinically stable patients with a virgin abdomen without features of closed-loop obstruction. Adhesions are the most common cause of SBO in this group of patients. Further large-scale prospective clinical studies with standardized NOM modality, homogenous clinical resolution indicators and long-term follow-up data are warranted to allow for quantitative analysis to reinforce this evidence.

BACKGROUND
Proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical procedure of choice for medically refractory ulcerative colitis and familial adenomatous polyposis. While rare, a pouch volvulus can occur. We aimed to determine the frequency, presentation, and management approach of pouch volvulus in patients with IPAA.
METHODS
A systematic search of published literature was performed by a medical reference librarian on 10 August 2018 and two independent reviewers identified relevant publications, extracted data, and assessed the methodological quality based on a validated tool. A retrospective review of the Mayo Clinic electronic medical records identified one case of pouch volvulus between January 2008 and August 2018.
RESULTS
The frequency of pouch volvulus from one large published study reporting long-term outcomes of IPAA was 0.18% (3/1,700). A total of 22 patients (18 ulcerative colitis) were included (median age 32 years, 73% females). Median time to volvulus after IPAA was 36 months while median interval to volvulus diagnosis from symptom onset was 24 hours. Abdominal pain was the most commonly reported symptom (76%). The diagnosis was made primarily by abdominal computed tomography (13/17 patients, 76%). Endoscopic treatment was successful in 1 of 11 patients (9%). Surgery was performed in 20 patients and pouch-pexy and pouch excision were the most frequent surgical operations. A redo IPAA was performed in five patients (25%).
CONCLUSION
Pouch volvulus is a rare but serious complication of IPAA and should be suspected even in the absence of obstruction symptoms. Endoscopic treatment often fails and surgery is effective when performed early.

Meta-Analysis
INTRODUCTION
The optimal timing of delivery for pregnancies complicated by prenatally diagnosed gastroschisis remains controversial. Therefore, the aim of this study was to find whether elective or expectant delivery is associated with improved neonatal outcome.
MATERIALS AND METHODS
MEDLINE and Embase databases were searched for studies up to 2021 that reported timing of delivery for prenatally diagnosed gastroschisis. A systematic review and meta-analysis were then performed in group 1: moderately preterm (gestational age [GA]: 34-35 weeks) elective delivery versus expectant management after GA 34-35 weeks; and group 2: near-term (GA: 36-37 weeks) elective delivery versus expectant management after GA 36-37 weeks. The following clinical outcomes were evaluated: length of stay (LOS), total parenteral nutrition (TPN) days, bowel morbidity (atresia, perforation, and volvulus), sepsis, time of first feeding, short gut syndrome and respirator days, and mortality.
RESULTS
Two randomized controlled trials (RCT)s and eight retrospective cohort studies were included, comprising 629 participants. Moderately preterm elective delivery failed to improve clinical outcomes. However, near-term elective delivery significantly reduced bowel morbidity (7.4 vs. 15.4%, relative risk = 0.37; 95% confidence interval [CI]: 0.18, 0.74; = 0.005; I2 = 0%) and TPN days (mean difference =-13.44 days; 95% CI: -26.68, -0.20; = 0.05; I2 = 45%) compared to expectant delivery. The mean LOS was 39.2 days after near-term delivery and 48.7 days in the expectant group ( = 0.06).
CONCLUSION
Based on the data analyzed, near-term elective delivery (GA 36-37 weeks) appears to be the optimal timing for delivery of pregnancies complicated by gastroschisis as it is associated with less bowel morbidity and shorter TPN days. However, more RCTs are necessary to better validate these findings.

Review
BACKGROUND
Ladd's Procedure has been the surgical intervention of choice in the management of congenital intestinal malrotation for the past century. Historically, the procedure included performing an appendectomy to prevent future misdiagnosis of appendicitis, since the location of the appendix will be shifted to the left side of the abdomen. This study consists of two parts. A review of the available literature on appendectomy as part of Ladd's procedure and then a survey sent to pediatric surgeons about their approach (to remove the appendix or not) while performing a Ladd's procedure and the clinical reasoning behind their approach.
METHODS
The study consists of 2 parts: (1) a systematic review was performed to extract articles that fulfill the inclusion criteria; (2) a short online survey was designed and sent by email to 168 pediatric surgeons. The questions in the survey were centered on whether a surgeon performs an appendectomy as part of the Ladd's procedure or not, as well as their reasoning behind either choice.
RESULTS
The literature search yielded five articles, the data from the available literature are inconsistent with performing appendectomy as part of Ladd's procedure. The challenge of leaving the appendix in place has been briefly described with minimal to no focus on the clinical reasoning. The survey demonstrated that 102 responses were received (60% response rate). Ninety pediatric surgeons stated performing an appendectomy as part of the procedure (88%). Only 12% of pediatric surgeons are not performing appendectomy during Ladd's procedure.
CONCLUSION
It is difficult to implement a modification in a successful procedure like Ladd's procedure. The majority of pediatric surgeons perform an appendectomy as part of its original description. This study has identified gaps in the literature pertaining to analyze the outcomes of performing Ladd's procedure without an appendectomy which should be explored in future research.

OBJECTIVES
Although systemic sclerosis (SSc) is known to affect the gastrointestinal (GI) tract, most of the literature focuses on esophageal, small intestinal, or anorectal manifestations. There have been no reviews focused on large bowel SSc complications in over 30 years. The aim of this study is to perform a systematic review of colonic manifestations and complications of SSc.
METHODS
An experienced librarian conducted a search of databases, including English and Spanish articles. The search used keywords including "systemic sclerosis," "scleroderma," and "colon." A systematic review was performed using Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Case reports/series were screened for validity by adapting from criteria published elsewhere.
RESULTS
Of 1,890 articles, 74 met selection criteria. Fifty-nine of the 77 articles were case reports/series. The most common article topics on colonic SSc complications were constipation/dysmotility (15), colonic volvulus (8), inflammatory bowel disease (7), microscopic colitis (6), megacolon (6), and telangiectasia (6). Colonic manifestations constituted 24% of articles on GI complications of SSc. There were a total of 85 cases (84% women, with a median age of onset of colon complication of 52 years). Limited cutaneous SSc phenotype (65.6%) was more common than diffuse (26.2%). Patients frequently had poor outcomes with high mortality related to colonic complications (27%). Recent studies explore contemporary topics such as the microbiome in SSc and prucalopride for chronic constipation in SSc.
DISCUSSION
Colonic complications comprise a large proportion of the published reports on GI symptoms afflicting patients with SSc and require raised diagnostic suspicion and deliberate action to avoid potentially serious complications including death.
