Meta-Analysis Review
PURPOSE
Although the principles of the Ladd's procedure for intestinal malrotation in children have remained unchanged since its first description, in the era of minimally invasive surgery it is controversial whether laparoscopy is advantageous over open surgery. The aim of our study was to determine whether the surgical approach for the treatment of malrotation had an impact on patient outcome.
METHODS
Using a defined strategy (PubMed, Cochrane, Embase and Web of Science MeSH headings), two investigators independently searched for studies comparing open versus laparoscopic Ladd's procedure in children. Case reports and opinion articles were excluded. Outcome measures included age at operation, time to full enteral feeding, length of hospital stay, and post-operative complications. Maneuvers were compared using Fisher's exact test and meta-analysis was conducted using RevMan 5.3. Data are expressed as mean ± SD.
RESULTS
Of 308 abstracts screened, 49 full-text articles were analyzed and nine (all retrospective) met our search criteria. Selected articles included 1003 patients, of whom 744 (74 %) underwent open surgery and 259 (26 %) laparoscopy. Patients who had open surgery were younger (0.9 ± 1.2 years) than those who underwent laparoscopy (2.6 ± 3 years; p < 0.0001). Laparoscopy was converted to open Ladd's in 25.3 % patients. Laparoscopy was associated with faster full enteral feeding (1.5 ± 0.3 days) in comparison to open surgery (4.6 ± 0.1 days, p < 0.0001). Length of hospital stay was shorter in the laparoscopic group (5.9 ± 4.3 days) than in the open group (11.2 ± 6.7 days; p < 0.0001). Open surgery was associated with higher overall post-operative complication rate (21 %) than laparoscopy (8 %; p < 0.0001). Although there was no difference in the prevalence of post-operative bowel obstruction (open, n = 10 %; laparoscopy, n = 0 % p = 0.07), post-operative volvulus was more frequent in the laparoscopy group (3.5 %) than in the open group (1.4 %, p = 0.04).
CONCLUSION
Comparative but non-randomized studies indicate that laparoscopic Ladd's procedure is not commonly performed in young children. Although one third of laparoscopic procedures is converted to open surgery, laparoscopy is associated with shorter time to full enteral feeds and length of hospital stay. However, laparoscopic Ladd's procedure seems to have higher incidence of post-operative volvulus. Prospective randomized studies with long follow-up are needed to confirm present outcome data and determine the safety and effectiveness of the laparoscopic approach.

Review
UNLABELLED
The duodenum is a short segment of the bowel that is frequently overlooked on radiologic examination. This unique portion occupies both intraperitoneal and extraperitoneal locations, with proximity to many visceral organs, including pancreas, stomach, aorta, and liver. This close proximity creates a differentiation challenge for the radiologist. Duodenal pathologies are categorized into neoplastic and nonneoplastic conditions. Majority of radiologists are familiar with duodenal neoplasm. However, duodenal involvement by a multitude of nonneoplastic conditions can be encountered. The majority of related radiology studies have concentrated on neoplasms of the duodenum-either primary or secondary. However, a broad range of nonneoplastic conditions merit discussion. In this review, multimodality imaging features of nonneoplastic duodenal diseases are discussed and emphasized.
OBJECTIVE
To conduct a systematic review of the frequent imaging features of nonneoplastic diseases of the duodenum, with an emphasis on accurate diagnosis so that the patient who will benefit from treatment can be identified.

Review
BACKGROUND AND AIM
Percutaneous endoscopic colostomy provides an alternative management option for patients with recurrent sigmoid volvulus who are considered too high risk to undergo surgery. We reviewed the literature to assess whether the National Institute for Health and Clinical Excellence guidelines published in 2006 supporting the use of percutaneous endoscopic colostomy are still valid.
METHODS
A systematic literature search was conducted using PubMed, Web of Science, and Embase. The exploded search terms "Percutaneous Endoscopic Colostomy" and "Sigmoid Volvulus" were used. Librarian support was used to ensure the maximum number of relevant articles were returned. Identified abstracts were then analyzed and included if they met the inclusion criteria.
RESULTS
Five observational studies and 5 case reports were identified that met the inclusion criteria. They provided data on 56 patients with recurrent sigmoid volvulus treated with percutaneous endoscopic colostomy placement. Sixteen of the 56 patients were treated with a single percutaneous endoscopic colostomy (PEC) tube while 38 patients were treated with 2 PEC tubes. For 2 patients the details of the procedure were unknown. Five patients developed major complications following the procedure: 1 patient developed peritonitis after 4 days, due to fecal contamination secondary to tube migration and 2 patients with cognitive impairment pulled their PEC tubes out. Two other patients died following PEC insertion. Nine patients developed minor complications following the procedure. The most commonly reported minor complication was infection at the PEC site. Four of 56 patients developed a recurrent sigmoid volvulus with a PEC tube in situ.
CONCLUSION
Although in these case series there is a 21 % risk of morbidity and 5 % risk of mortality from the use of a PEC, this is favorable compared to the mortality risk of 6.6 % to 44 % reported with operative intervention. This review of contemporary literature therefore supports the use of PEC in frail and elderly patients.

Review
AIM
To determine the incidence of internal hernias after laparoscopic colorectal surgery and evaluate the risk factors and strategies in the management of this serious complication.
METHOD
Two databases (MEDLINE from 1946 and Embase from 1949) were searched to mid-September 2015. The search terms included volvulus or internal hernia and laparoscopic colorectal surgery or colorectal surgery or anterior resection or laparoscopic colectomy. We found 49 and 124 articles on MEDLINE and Embase, respectively, an additional 15 articles were found on reviewing the references. After removal of duplicates, 176 abstracts were reviewed, with 33 full texts reviewed and 15 eligible for qualitative synthesis.
RESULTS
The incidence of internal hernia after laparoscopic colorectal surgery is low (0.65%). Thirty-one patients were identified. Five cases were from two prospective studies (5/648, 0.8%), 20 cases were from seven retrospective studies (20/3165, 0.6%) and six patients were from case reports. Of the 31 identified cases, 21 were associated with left-sided resection, four with right sided resection, two with transverse colectomy, one with a subtotal colectomy and in three cases the operation was not specified. The majority of cases (64.3%) were associated with a restorative left sided resection. Nearly all cases occurred within 4 months of surgery. All patients required re-operation and reduction of the internal hernia and 35.7% of cases required a bowel resection. In 52.2% of cases, the mesenteric defect was closed at the second operation and 52.6% of cases were successfully managed laparoscopically. There were three deaths (0.08%).
CONCLUSION
Mesenteric hernias are a rare but important complication of laparoscopic colorectal surgery. The evidence does not support routine closure for all cases, but selective closure of the mesenteric defect during left-sided restorative procedures in high-risk patients at the initial surgery may be considered.

Meta-Analysis Review
OBJECTIVE
To assess the role of screening and prophylactic surgery for intestinal rotational abnormalities (IRAs) in asymptomatic patients with heterotaxy.
STUDY DESIGN
PubMed, Embase, and Cinahl were searched electronically to determine the overall incidence of IRAs in heterotaxy; the detection rate of IRAs associated with screening; the incidence of midgut volvulus in patients without screening; and the incidence of morbidity and mortality after prophylactic and emergency Ladd procedures. Relevant data were computed with a meta-analysis of proportions. Between-study heterogeneity was assessed with the I(2) statistic.
RESULTS
From 276 papers identified, 24 studies with a total of 1433 patients with heterotaxy were included for systematic review. No randomized study was identified. True incidence of IRA in heterotaxy could not be ascertained through meta-analysis. In patients who underwent screening, the incidence of IRA was 58%. Acute midgut volvulus occurred in 5.8% of those who did not undergo screening. Postoperative mortality after Ladd procedure mainly was associated with cardiac insufficiency, and overall it was significantly greater in the emergency group compared with the prophylactic group (18% vs 5.6%). The complication rate also was greater in case of emergency vs prophylactic abdominal surgery (27% vs 16%); adhesional small bowel obstruction was the most common complication overall (6%).
CONCLUSION
The screen-detected incidences of IRA and acute midgut volvulus were significantly greater in heterotaxy than the normal population. Prophylactic Ladd procedure was associated with less morbidity and mortality compared with emergency surgery. A long-term prospective randomized trial is needed to define the indication for screening and prophylactic treatment of IRA in heterotaxy.

Review
BACKGROUND
Disparity still exists in the outcome of neonatal surgery between high-income countries and low-income and middle-income countries. This study reviews publications on neonatal surgery in Africa over 20 years with a focus on challenges of management, trends in outcome, and potential interventions to improve outcome.
METHODS
We did a literature review by searching PubMed and African Index Medicus for original articles published in any language between January 1995 and September 2014. A data extraction sheet was used to collect information, including type of study, demographics, number of cases, outcome, challenges, and suggestions to improve outcome.
RESULTS
A total of 51 studies from 11 countries met the inclusion criteria. The 16 studies in the first 10 years (1995-2004; group A) were compared with the 35 in the last 10 years (2005-2014; group B). Nigeria (n = 32; 62.7 %), South Africa (n = 7; 13.7 %), Tanzania (n = 2; 3.9 %), and Tunisia (n = 2; 3.9 %) were the predominant sources of the publications, which were retrospective in 38 (74.5 %) studies and prospective in 13 (25.5 %) studies. The mean sample size of the studies was 95.1 (range 5-640). Overall, 4849 neonates were studied, with median age of 6 days (range 1-30 days). Common neonatal conditions reported were intestinal atresia in 28 (54.9 %) studies, abdominal wall defects in 27 (52.9 %), anorectal malformations 25 in (49.0 %), and Hirschsprung's disease, necrotising enterocolitis, and volvulus neonatorum in 23 (45.1 %) each. Mortality was lowest (<3 %) in spina bifida and facial cleft procedures, and highest (>50 %) in emergency neonatal surgeries involving bowel perforation, bowel resection, congenital diaphragmatic hernia, oesophageal atresia, and ruptured omphalocele or gastroschisis. Overall average mortality rate was higher in group A than group B (36.9 vs 29.1 %; p < 0.001), and varied between the groups for some conditions. The major documented challenges were delayed presentation and inadequate facilities in 39 (76.5 %) studies, dearth of trained support personnel in 32 (62.7 %), and absence of neonatal intensive care in 29 (56.9 %). The challenges varied from country to country but did not differ in the two groups.
CONCLUSION
Improvement has been achieved in outcomes of neonatal surgery in Africa in the past two decades, although several of the studies reviewed are retrospective and poorly designed. Cost effective adaptations for neonatal intensive care, improved health-care funding, coordinated neonatal surgical care via regional centres, and collaboration with international partners are potential interventions that could help to address the challenges and further improve outcome.

Meta-Analysis Review
BACKGROUND
Onchocerciasis, also known as "river blindness," is a parasitic disease that is caused by infection from the filarial nematode (roundworm), Onchocerca volvulus. Nematodes are transmitted from person to person by blackflies of the Simulium genus, which usually breed in fast flowing streams and rivers. The disease is the second leading infectious cause of blindness in endemic areas.Ivermectin (a microfilaricide) is widely distributed to endemic populations for prevention and treatment of onchocerciasis. Doxycycline, an antibiotic, targets Wolbachia organisms that are crucial to the survival of adult onchocerca (macrofilaricide). Combined treatment with both drugs is believed to cause direct microfilarial death by ivermectin and indirect macrofilarial death by doxycycline. Long-term reduction in the numbers of microfilaria in the skin and eyes and in the numbers of adult worms in the body has the potential to reduce the transmission and occurrence of onchocercal eye disease.
OBJECTIVES
The primary aim of this review was to assess the effectiveness of doxycycline plus ivermectin versus ivermectin alone for prevention and treatment of onchocerciasis. The secondary aim was to assess the effectiveness of doxycycline plus ivermectin versus ivermectin alone for prevention and treatment of onchocercal ocular lesions in communities co-endemic for onchocerciasis and Loa loa (loiasis) infection.
SEARCH METHODS
We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (Issue 7, 2015), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to July 2015), EMBASE (January 1980 to July 2015), PubMed (1948 to July 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (1982 to July 2015), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) (last searched 1 July 2014), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 15 July 2015.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) that had compared doxycycline plus ivermectin versus ivermectin alone. Participants with or without one or more characteristic signs of ocular onchocerciasis resided in communities where onchocerciasis was endemic.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trial eligibility and extracted data. We used standard methodological procedures as expected by Cochrane.
MAIN RESULTS
We identified three RCTs including a total of 466 participants with a diagnosis of onchocerciasis. All trials compared doxycycline plus ivermectin versus ivermectin alone. One study investigated improvement in visual impairment at six-month follow-up; the other two studies measured microfilarial loads in skin snips to assess sustained effects of treatment at follow-up of 21 months or longer. The studies were conducted at various centers across three countries (Cameroon, Ghana, and Liberia). We judged all studies to be at overall high risk of bias because of inadequate randomization and lack of masking (one study), missing data (two studies), and selective outcome reporting (three studies).Only one study measured visual outcomes. This study reported uncertainty about the difference in the proportion of participants with improvement in visual impairment at six-month follow-up for doxycycline plus ivermectin compared with ivermectin alone (risk ratio (RR) 1.06, 95% confidence interval (95% CI) 0.80 to 1.39; 240 participants; very low-quality evidence). No participant in either group showed improvement in optic atrophy, chorioretinitis, or sclerosing keratitis at six-month follow-up. More participants in the doxycycline plus ivermectin group than in the ivermectin alone group showed improvement in iridocyclitis (RR 1.24, 95% CI 0.69 to 2.22) and punctate keratitis (RR 1.43, 95% CI 1.02 to 2.00) at six-month follow-up; however, we graded these results as very low quality.Two studies reported that a six-week course of doxycycline may result in Wolbachia depletion and macrofilaricidal and sterilizing activities in female Onchocerca worms; however, no analysis was possible because data were missing and incomplete (graded evidence as very low quality). Adverse events were reported in 16 of 135 (12%) participants in one of these studies and included itching, headaches, body pains, and vertigo; no difference between treatment groups was reported for any adverse event. The second study reported that one (1.3%) participant in the doxycycline plus ivermectin group had bloody diarrhea after treatment was initiated.
AUTHORS' CONCLUSIONS
Available evidence on the effectiveness of doxycycline plus ivermectin compared with ivermectin alone in preventing and treating onchocerciasis is unclear. Limited evidence of very low quality from two studies indicates that a six-week course of doxycycline followed by ivermectin may result in more frequent macrofilaricidal and microfilaricidal activity and sterilization of female adult Onchocerca compared with ivermectin alone; however, effects on vision-related outcomes are uncertain. Future studies should consider the effectiveness of treatments in preventing visual acuity and visual field loss and their effects on anterior and posterior segment lesions, particularly chorioretinitis. These studies should report outcomes in a uniform and consistent manner at follow-up of three years or longer to allow detection of meaningful changes in vision-related outcomes.

Annals of Surgery Dec 2016(1) Is screening of intestinal rotational anatomy obligatory in "asymptomatic" patients with heterotaxy? (2) Does detection of an anomaly warrant surgical correction? (Review)
Review
OBJECTIVE
(1) Is screening of intestinal rotational anatomy obligatory in "asymptomatic" patients with heterotaxy? (2) Does detection of an anomaly warrant surgical correction?
SUMMARY OF BACKGROUND DATA
Heterotaxy is an abnormal arrangement of thoraco-abdominal viscera across a left-to-right axis. Intestinal rotational anomalies are frequent among patients with heterotaxy, but debate exists as to whether they are benign in nature, requiring careful observation alone, or if surgical correction is warranted to prevent obstruction or midgut volvulus.
METHODS
A systematic review [according to PRISMA guidelines] was conducted using CINAHL, EMBASE, Medline, and Cochrane Databases. Article quality was assessed using MINORS criteria. Conference proceedings and unpublished data were screened additionally.
RESULTS
Nineteen studies met the eligibility criteria but reporting was adequate for 9. All were observational studies. These included a total of 414 patients managed expectantly, that is, "asymptomatic patients" in whom no intestinal rotation screening was undertaken (group A), 191 cases in whom screening was performed routinely (group B), and 92 patients considered "symptomatic" of potential rotational anomalies and therefore underwent imaging or laparotomy (group C). In group A, 1 patient developed symptoms attributable to malrotation in whom laparotomy confirmed the diagnosis (0.24%). Among groups B and C, 151 had Ladd's operations (53%) and 14 cases of malrotation with obstruction or volvulus were described (4.9%), of which 2 "symptomatic patients" died before laparotomy. Overall surgical complication rate was 17% with 30-day mortality rate of 2.6% to 4.6%.
CONCLUSION
The evidence base for screening "asymptomatic" patients is weak especially considering the life-limiting comorbidities.

Review
BACKGROUND
The management of intestinal rotational abnormalities (IRA) in heterotaxy syndrome (HS) remains inconsistent. Because of the high incidence of malrotation in HS, screening of asymptomatic patients is standard of care in some institutions. The Ladd procedure is the treatment for malrotation, and has been reported to have high complication rates in HS patients.
METHODS
We performed a systematic review of publications describing IRA in pediatric HS patients from January 1993 to present. The incidence of volvulus on surgical exploration was determined. Perioperative and long-term outcomes were analyzed to determine complication and mortality rates.
RESULTS
Eleven retrospective studies describing 649 HS patients were identified. Of all patients with HS, 27% (176/649) underwent Ladd procedure. Only 1.2% (8/649) of HS patients included had volvulus. Postoperative complications occurred in 25 patients (14%), including a 10% incidence of small bowel obstruction. Perioperative and overall mortality rates after Ladd procedure were 3% and 21%, respectively. Six studies described mesenteric width, reporting 43% to have narrow mesentery.
CONCLUSION
The Ladd procedure is not without significant morbidity and mortality in heterotaxy patients. Further prospective studies should investigate predictors of mesenteric width to spare the unnecessary morbidity of surgery in patients who are at low risk for volvulus.

BACKGROUND
Advances in diagnostic techniques and perioperative care have greatly improved the outcome of neonatal surgery. Despite this, disparity still exists in the outcome of neonatal surgery between high-income countries and low-income and middle-income countries. This study reviews publications on neonatal surgery in Africa over 20 years with a focus on challenges of management, trends in outcome, and potential interventions to improve outcome.
METHODS
We did a literature review by searching PubMed and African Index Medicus for original articles published in any language between January, 1995, and September, 2014, with the search terms "neonatal surgery" and "Africa", further supplemented by "(surgery OR anaesthesia) AND (neonatal OR newborn) AND (developing countries OR Africa)". A data extraction sheet was used to collect information, including type of study, demographics, number of cases, outcome, challenges, and suggestions to improve outcome. For the meta-analysis, data were analysed by χ(2) test or Student's t-test as appropriate. In all, the significance level was set to p<0·05.
FINDINGS
We identified 859 published papers, of which 51 studies from 11 countries met the inclusion criteria. The 16 studies in the first 10 years (before 2005; group A) were compared with the 35 in the last 10 years (2005-14; group B). Nigeria (n=32; 62·7%), South Africa (n=7; 13·7%), Tanzania (n=2; 3·9%), and Tunisia (n=2; 3·9%) were the predominant source of the publications, of which were retrospective in 38 (74·5%) studies and prospective in 13 (25·5%) studies. The mean sample size of the studies was 97·8 (range 5-640). Overall, 4989 neonates were studied, with median age of 6 days (range 1-30). Common neonatal conditions reported were intestinal atresia in 28 (54·9%) studies, abdominal wall defects in 27 (52·9%), anorectal malformations in 24 (47·1%), and Hirschsprung's disease, necrotising enterocolitis, and volvulus neonatorum in 23 (45·1%) each. Mortality was lowest (<3%) in spina bifida and facial cleft procedures, and highest (>50%) in emergency neonatal surgeries involving bowel perforation, bowel resection, congenital diaphragmatic hernia, oesophageal atresia, and ruptured omphalocele or gastroschisis. Overall average mortality rate was higher in group A than in group B (36·9% vs 29·1%; p<0·001), but mortality did not vary between the groups for similar neonatal conditions. The major documented challenges were delayed presentation and inadequate facilities in 39 (76·5%) studies, dearth of trained support personnel in 32 (62·7%), and absence of neonatal intensive care in 29 (56·9%). The challenges varied from country to country but did not differ in the two groups.
INTERPRETATION
Improvement has been achieved in outcomes of neonatal surgery in Africa in the past two decades, although several of the studies reviewed are retrospective and poorly designed. Cost-effective adaptations for neonatal intensive care, improved health-care funding, coordinated neonatal surgical care via regional centres, and collaboration with international partners are potential interventions that could help to address the challenges and further improve outcome.
