Comparative Study Meta-Analysis
OBJECTIVE
The outcomes of children with Choledochal cyst who undergo laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy versus open cyst excision and Roux-en-Y hepaticojejunostomy have not been adequately compared. We conducted a systematic review and meta-analysis to gain further insight into the efficacy and safety of laparoscopic excision in children with choledochal cysts.
METHODS
A systematic search of PubMed, Embase, Cochrane Central Register, and ClinicalTrials.gov databases from January 1973 to January 31, 2020 was performed utilizing the PRISMA guidelines. Short-term, long-term and total postoperative complications were the primary endpoint measurements, whereas intraoperative outcomes and other postoperative outcomes were the secondary endpoints.
RESULTS
The final analysis included 14 retrospective cohorts comprising 1767 patients. There were no significant differences in the patients' short-term postoperative complications (RR = -1.08; 95% CI = -1.72 to -0.67) between the 2 approaches. However, improvements in long-term (RR = 0.09; 95% CI = 0.01 to 0.18) and total postoperative complications (RR = -0.29; 95% CI = -0.40 to -0.21), estimated intraoperative blood loss and transfusion, time of initial feeding, and length of hospital stay were observed in patients who underwent laparoscopic excision when compared to those who underwent open surgery.
CONCLUSIONS
Laparoscopic cyst excision and Roux-en-Y hepaticojejunostomy provides similar or even improved intraoperative, postoperative outcomes when compared to open excision for children with Choledochal cyst.

Review
INTRODUCTION
Small bowel lipomas are rarely encountered benign adipose growths found within the small intestine wall or mesentery. Limited up-to-date evidence exists regarding such lipomas. We aim to aid clinical decision-making and improve patient outcomes through this comprehensive review.
METHODOLOGY
The terms 'small bowel,' 'small intestine,' 'jejunum' and 'ileum' were combined with 'lipoma.' EMBASE, Medline and PubMed database searches were performed. All papers published in English from 01/01/2000-31/12/2019 were included. Simple statistical analysis (-test, Anova) was performed.
RESULTS
142 papers yielded 147 cases (adults = 138, pediatric = 9). Male = 88, female = 59 (average age = 49.9 years). Presenting symptoms: abdominal pain = 68.7%; nausea/vomiting = 35.3%, hematochezia/GI bleeding = 33.3%; anaemia = 10.9%; abdominal distension = 12.2%; constipation = 8.9%; weight loss = 7.5%. Mean preceding symptom length = 58.1 days (symptoms >1 year excluded (n = 9)). Diagnostic imaging utilised: abdominal X-Ray = 33.3%; endoscopy = 46.3%; CT = 78.2%; ultrasound = 23.8%. 124/137 (90.5%) required definitive surgical management (laparotomy = 89, laparoscopcic = 35). 9 patients were successfully managed endoscopically. Lipoma location: ileum = 59.9%, jejunum = 32%, mesentery = 4.8%. Maximal recorded lipoma size ranged 1.2-22 cm.Mean maximum lipoma diameter and management strategy comparison: laparotomy 5.6 cm, laparoscopic = 4.4 cm, endoscopic = 3.7 cm, conservative = 4.5 cm. One-way Anova test, p value = 0.21. Average length of stay (LOS) was 7.4 days (range = 2-30). T-test p value = 0.13 when comparing management modalities and LOS. 4 complications, 0 mortality.
CONCLUSIONS
Important previously undocumented points are illustrated; a clearer symptom profile, diagnostic investigations utilised, size and site of lipomas, types and effectiveness of management modalities, associated morbidity and mortality. Open surgery remains the primary management. No statistically significant difference in LOS and lipoma size is demonstrated between management strategies. Endoscopic and laparoscopic techniques may reduce utilising invasive surgery in the future as skillset and availability improve.

Journal of Gastrointestinal and Liver... Sep 2020Starting from a case presentation, this review aims to present literature data on inflammatory fibroid polyps (IFPs) of the small intestine.
AIM
Starting from a case presentation, this review aims to present literature data on inflammatory fibroid polyps (IFPs) of the small intestine.
METHODS
Case report and systematic review. A comprehensive systematic review of English literature using PubMed was conducted, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The used key words were: "inflammatory fibroid polyp" or "Vanek", including only cases with IFPs localized of the small intestine, published from 1976 to 2019.
RESULTS
We present a case of a 38-year old patient with intestinal IFP presenting with acute abdomen due to intussusception diagnosed with ultrasound (US) based on a target sign and visible solid tumor in the small intestine leading to prompt surgical treatment. A diagnosis of IFP was made based on the pathohistological findings. Moreover, a systematic review of small intestine IFPs was conducted which is, to our knowledge, the first comprehensive systematic literature review on this topic. The analysis included 53 case reports or case series concerning 77 cases of small bowel IFPs. The patients were aged from 4 to 75 years (average 45.2), with a female predominance (59.7%). The most common localization was the ileum in 77.9% cases, followed by the jejunum (13%) and the duodenum (6.5%). The most common clinical presentation was abdominal pain due to intussusception (63.6%). Regarding diagnostic methods, computed tomography (CT) was frequently used as primary diagnostic method (26%) followed by exploratory laparotomy (16.9%), endoscopy (7.8%) and US (6.5%). Combination of US and CT contributed to the diagnosis in 9.1% of cases. The majority of cases were treated surgically (92.21%), while only a minority benefited of minimally invasive techniques such as endoscopy.
CONCLUSIONS
Small bowel IFPs, ones of the least common benign tumors, are characterized by variable clinical signs and symptoms and can potentially lead to serious consequences for the patient.

Comparative Study Meta-Analysis
Endoscopic full-thickness suturing plus argon plasma mucosal coagulation versus argon plasma mucosal coagulation alone for weight regain after gastric bypass: a systematic review and meta-analysis.
BACKGROUND AND AIMS
Endoscopic transoral outlet reduction (TORe) has been used to manage weight regain after Roux-en-Y gastric bypass. We conducted a meta-analysis to summarize the efficacy and safety of the two most commonly used techniques: full-thickness suturing plus argon plasma mucosal coagulation (ft-TORe) and argon plasma mucosal coagulation alone (APMC-TORe).
METHODS
A literature search of publication databases was performed from their inception to February 2020 for relevant studies. The outcomes of interest were percentage total body weight loss, gastrojejunal anastomosis (GJA) diameter, and adverse events (AEs). The pooled effect estimates were analyzed using a random-effects model. Meta-regression was conducted to identify associations between GJA diameter and weight loss.
RESULTS
Nine ft-TORe (n = 737) and 7 APMC-TORe (n = 888) studies were included. APMC-TORe was performed as a series of sessions (mean number of sessions ranging from 1.2 to 3), whereas ft-TORe was mostly performed as a single session. Percentage total body weight loss was 8.0% (95% confidence interval [CI], 6.3%-9.7%), 9.5% (95% CI, 8.1%-11.0%), and 5.8% (95% CI, 4.3%-7.1%) after ft-TORe and 9.0% (95% CI, 4.1%-13.9%), 10.2% (95% CI, 8.4%-12.1%), and 9.5% (95% CI, 5.7%-13.2%) after APMC-TORe at 3, 6, and 12 months, respectively, with no weight-loss difference at 3 and 6 months (P > .05). Only one severe AE was observed after APMC-TORe and none after ft-TORe. Stricture formation was the most common AE (ft-TORe 3.3% and APMC-TORe 4.8%, P = .38). All were successfully treated by endoscopic dilation or conservative treatment. Smaller aperture of the post-TORe GJA and greater change in the GJA diameter correlated with greater weight loss in APMC-TORe and numerical trends in ft-TORe.
CONCLUSIONS
This meta-analysis demonstrates that both ft-TORe and APMC-TORe offer significant and comparable weight-loss outcomes with a high and comparable safety profile. However, APMC-TORe typically required multiple endoscopic sessions. Identifying a goal for the final and change in GJA diameter could be useful treatment targets.

Meta-Analysis Review
BACKGROUND
Additional studies comparing several reconstruction methods after proximal gastrectomy have been published; of note, it is necessary to update systematic reviews and meta-analysis from the current evidence-based literature.
AIM
To expand the current knowledge on feasibility and safety, and also to analyze postoperative outcomes of several reconstructive techniques after proximal gastrectomy.
METHODS
PubMed, Google Scholar, and Medline databases were searched for original studies, and relevant literature published between the years 1966 and 2019 concerning various reconstructive techniques on proximal gastrectomy were selected. The postoperative outcomes and complications of the reconstructive techniques were assessed. Meta-analyses were performed using Rev-Man 5.0. A total of 29 studies investigating postoperative outcomes of double tract reconstruction, jejunal pouch interposition, jejunal interposition, esophagogastrostomy, and double flap reconstruction were finally selected in the quantitative analysis.
RESULT
Pooled incidences of reflux esophagitis for double tract reconstruction, jejunal pouch interposition, jejunal interposition esophagogastrostomy, and double flap reconstruction were 8.6%, 13.8%, 13.8%, 19.3%, and 8.9% respectively. Meta-analysis showed a decreased length of hospital in the JI group as compared to the JPI group (heterogeneity: Chi = 1.34, df = 1 (P = 0.25); I = 26%, test for overall effect: Z = 2.22 (P = 0.03). There was also a significant difference between JI and EG in length of hospital stay with heterogeneity: Chi = 1.40, df = 3 (P = 0.71); I = 0%, test for overall effect: Z = 5.04 (P < 0.00001). Operative time was less in the EG group as compared to the JI group (heterogeneity: Chi = 31.09, df = 5 (P < 0.00001); I = 84%, test for overall effect: Z = 32.35 (P < 0.00001).
CONCLUSION
Although current reconstructive techniques present excellent anti-reflux efficacy, the optimal reconstructive method remains to be determined. The double flap reconstruction proved to lower the rate of complication, but the DTR, JI, JPI, and EG groups showed higher incidence of complications in anastomotic leakage, anastomotic stricture, and residual food. In the meta-analysis result, the complications between the JI, JPI, and EG were comparable but the EG group showed to have better postoperative outcomes concerning the operative time, blood loss, and length of hospital stay.

Comparative Study
INTRODUCTION
Laparoscopic pancreatic reconstruction is a challenging procedure and is considered the Achilles' heel of laparoscopic pancreatectomy. Multiple techniques of laparoscopic pancreatic reconstruction have been reported, but the optimal technique remains unclear.
AREAS COVERED
This paper provides a brief introduction to the developmental status and major related complications of laparoscopic pancreatic reconstruction. We reviewed all published literature on the technology of laparoscopic pancreatic reconstruction within the last 5 years and herein discuss the advantages and disadvantages of different reconstruction methods. We also discuss several details of different reconstruction techniques in terms of their significance to the operation and complications.
EXPERT OPINION
No individual method of laparoscopic pancreatic reconstruction is considered optimal for all conditions. The reconstruction strategy should be based on the surgeon's proficiency with laparoscopic technology and the patient's individual risk factors. Personalized methods of pancreatic reconstruction may more effectively reduce morbidity and mortality.

Capsule retention is the most common adverse event associated with video capsule endoscopy. The use of double-balloon enteroscopy-assisted capsule endoscope retrieval has been increasingly reported in recent years. However, evidence is limited regarding its success rate, associated factors, and subsequent clinical outcomes. A systematic review of relevant studies published before January 2019 was performed. Successful retrieval rate and associated factors, rate of endoscopic balloon dilation, and outcomes after double-balloon enteroscopy were summarized and pooled. Within 154 associated original articles, 12 including 150 cases of capsule retrieval by double-balloon enteroscopy were included. The estimated pooled successful retrieval rate was 86.5% (95% confidence interval, 75.6-95.1%). Anterograde approach and capsules retained in the jejunum or trapped by malignant strictures were associated with a higher successful retrieval rate than the retrograde approach (62/83 [74.7%] vs. 10/38 [26.3%], < .001) and capsules retained in the ileum (41/41 [100.0%] vs. 43/58 [74.1%], < .001) or trapped by benign strictures (21/21 [100.0%] vs. 65/83 [78.3%], = .043). Endoscopic balloon dilation was performed in 38.8% (95% confidence interval, 22.3-56.3%) of patients with benign strictures. Two perforations (1.3%) were reported as severe adverse events after double-balloon enteroscopy. A significantly lower surgery rate was found among cases with successful video capsule removal compared with unsuccessful cases (7.2% vs. 38.5%, = .002). Double-balloon enteroscopy is feasible and safe for removing retained video capsule endoscopes, and its use could decrease the need for surgery in patients with benign strictures and facilitate subsequent surgery in patients with malignant strictures.

Meta-Analysis
BACKGROUND
Postoperative pancreatic fistula (POPF) remains a major cause of morbidity following pancreaticoduodenectomy (PD). This network meta-analysis (NMA) compared techniques of pancreatic anastomosis following PD to determine the technique with the best outcome profile.
METHODS
A systematic literature search was performed on the Scopus, EMBASE, Medline and Cochrane databases to identify RCTs employing the international study group of pancreatic fistula (ISGPF) definition of POPF. The primary outcome was clinically relevant POPF.
RESULTS
Five techniques of pancreatic anastomosis following PD were directly compared in 15 RCTs comprising 2428 patients. Panreatojejunostomy (PJ) end-to-side invagination vs. PJ end-to-side duct-to-mucosa was the most frequent comparison (n = 7). Overall, 971 patients underwent PJ end-to-side duct-to-mucosa, 791 patients PJ end-to-side invagination, 505 patients pancreatogastrostomy (PG) end-to-side invagination, 98 patients PG end-to-side duct-to-mucosa, and 63 patients PJ end-to-side single layer. PG duct-to-mucosa was associated with the lowest rates of clinically relevant POPF, delayed gastric emptying, intra-abdominal abscess, all postoperative morbidity and postoperative mortality, the shortest operative time and postoperative hospital stay and the lowest volume of intra-operative blood loss.
CONCLUSION
Duct-to-mucosa pancreaticogastrostomy was associated with the lowest rates of clinically relevant POPF and had the best outcome profile among all techniques of pancreatico-anastomosis following PD.

Meta-Analysis
BACKGROUND
Ultrasound (US) is a noninvasive method of assessing the bowel that can be used to screen for bowel pathology, such as Inflammatory Bowel Disease, in children. Knowledge about US findings of the bowel in healthy children is important for interpreting US results in cases where disease is suspected.
OBJECTIVE
To assess the bowel wall thickness in different bowel segments in healthy children and to assess differences in bowel wall thickness among pediatric age categories.
MATERIALS AND METHODS
We conducted a systematic search in the PubMed, Embase, Cochrane, and CINAHL databases for studies describing bowel wall thickness measured by transabdominal US in healthy children. We excluded studies using contrast agent. We calculated the pooled mean and standard deviation scores and assessed differences among age categories (0-4 years, 5-9 years, 10-14 years, 15-18 years), first with analysis of variance (ANOVA) and further with subsequent Student's t-tests for independent samples, corrected for multiple testing.
RESULTS
We identified 191 studies and included 7 of these studies in the systematic review. Reported bowel wall thickness values ranged from 0.8 mm to 1.9 mm in the small bowel and from 1.0 mm to 1.9 mm in the colon. The mean colonic bowel wall thickness is larger in children ages 15-19 years compared to 0-4 years (range in difference: 0.3-0.5 mm [corrected P<0.02]).
CONCLUSION
The reported upper limit of bowel wall thickness in healthy children is 1.9 mm in the small bowel and the colon, and mean thickness increases slightly with age in jejunum and colon. These values can be used as guidance when screening for bowel-related pathology in children.

Meta-Analysis
BACKGROUND
Colonic mast cells have been proposed to be related to the pathophysiology of irritable bowel syndrome (IBS). Whether mast cell counts are altered in the small intestine, a less-explored region in patients with IBS is not completely clear.
METHODS
PubMed and EMBASE were searched for case-control studies on mast cell count/density in the small intestine of patients with IBS vs controls through February 2019. Mast cell counts were separately analyzed in the duodenum, jejunum, and ileum. Data were pooled using the standardized mean difference (SMD) method. When zero was not within the 95% confidence interval (CI), the SMD was considered significant.
KEY RESULTS
Data from 344 patients with IBS and 229 healthy controls from three studies in the duodenum, six in the jejunum, and five in the ileum were pooled in this meta-analysis. The number of mast cells was significantly higher in the ileum (SMD: 1.78 [95% CI: 0.89, 2.66]) of patients with IBS. Mast cell counts were not significantly different in the duodenum (SMD: 0.81 [-0.06, 1.67]) or the jejunum (SMD: 0.58 [-0.03, 1.19]) of patients with IBS vs healthy controls.
CONCLUSIONS AND INFERENCES
Mast cells are increased in the small intestine of IBS vs controls, mainly in the ileum. Future studies should address whether such findings are IBS subtype or gender-dependent. Methodological variations, single-center bias, and the limited number of studies included in this meta-analysis may affect the final results.
