Meta-Analysis
BACKGROUND
Infantile hypertrophic pyloric stenosis (IHPS) is a disorder of young children (aged one year or less) and can be treated by laparoscopic (LP) or open (OP) longitudinal myotomy of the pylorus. Since the first description in 1990, LP is being performed more often worldwide.
OBJECTIVES
To compare the efficacy and safety of open versus laparoscopic pyloromyotomy for IHPS.
SEARCH METHODS
We conducted a literature search on 04 February 2021 to identify all randomised controlled trials (RCTs), without any language restrictions. We searched the following electronic databases: MEDLINE (1990 to February 2021), Embase (1990 to February 2021), and the Cochrane Central Register of Controlled Trials (CENTRAL). We also searched the Internet using the Google Search engine (www.google.com) and Google Scholar (scholar.google.com) to identify grey literature not indexed in databases.
SELECTION CRITERIA
We included RCTs and quasi-randomised trials comparing LP with OP for hypertrophic pyloric stenosis.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened references and extracted data from trial reports. Where outcomes or study details were not reported, we requested missing data from the corresponding authors of the primary RCTs. We used a random-effects model to calculate risk ratios (RRs) for binary outcomes, and mean differences (MDs) for continuous outcomes. Two review authors independently assessed risks of bias. We used GRADE to assess the certainty of the evidence for all outcomes.
MAIN RESULTS
The electronic database search resulted in a total of 434 records. After de-duplication, we screened 410 independent publications, and ultimately included seven RCTs (reported in 8 reports) in quantitative analysis. The seven included RCTs enrolled 720 participants (357 with open pyloromyotomy and 363 with laparoscopic pyloromyotomy). One study was a multi-country trial, three were carried out in the USA, and one study each was carried out in France, Japan, and Bangladesh. The evidence suggests that LP may result in a small increase in mucosal perforation compared with OP (RR 1.60, 95% CI 0.49 to 5.26; 7 studies, 720 participants; low-certainty evidence). LP may result in up to 5 extra instances of mucosal perforation per 1,000 participants; however, the confidence interval ranges from 4 fewer to 44 more per 1,000 participants. Four RCTs with 502 participants reported on incomplete pyloromyotomy. They indicate that LP may increase the risk of incomplete pyloromyotomy compared with OP, but the confidence interval crosses the line of no effect (RR 7.37, 95% CI 0.92 to 59.11; 4 studies, 502 participants; low-certainty evidence). In the LP groups, 6 cases of incomplete pyloromyotomy were reported in 247 participants while no cases of incomplete pyloromyotomy were reported in the OP groups (from 255 participants). All included studies (720 participants) reported on postoperative wound infections or abscess formations. The evidence is very uncertain about the effect of LP on postoperative wound infection or abscess formation compared with OP (RR 0.59, 95% CI 0.24 to 1.45; 7 studies, 720 participants; very low-certainty evidence). The evidence is also very uncertain about the effect of LP on postoperative incisional hernia compared with OP (RR 1.01, 95% CI 0.11 to 9.53; 4 studies, 382 participants; very low-certainty evidence). Length of hospital stay was assessed by five RCTs, including 562 participants. The evidence is very uncertain about the effect of LP compared to OP (mean difference -3.01 hours, 95% CI -8.39 to 2.37 hours; very low-certainty evidence). Time to full feeds was assessed by six studies, including 622 participants. The evidence is very uncertain about the effect of LP on time to full feeds compared with OP (mean difference -5.86 hours, 95% CI -15.95 to 4.24 hours; very low-certainty evidence). The evidence is also very uncertain about the effect of LP on operating time compared with OP (mean difference 0.53 minutes, 95% CI -3.53 to 4.59 minutes; 6 studies, 622 participants; very low-certainty evidence).
AUTHORS' CONCLUSIONS
Laparoscopic pyloromyotomy may result in a small increase in mucosal perforation when compared with open pyloromyotomy for IHPS. There may be an increased risk of incomplete pyloromyotomy following LP compared with OP, but the effect estimate is imprecise and includes the possibility of no difference. We do not know about the effect of LP compared with OP on the need for re-operation, postoperative wound infections or abscess formation, postoperative haematoma or seroma formation, incisional hernia occurrence, length of postoperative stay, time to full feeds, or operating time because the certainty of the evidence was very low for these outcomes. We downgraded the certainty of the evidence for most outcomes due to limitations in the study design (most outcomes were susceptible to detection bias) and imprecision. There is limited evidence available comparing LP with OP for IHPS. The included studies did not provide sufficient information to determine the effect of training, experience, or surgeon preferences on the outcomes assessed.

Review
Delayed emptying of the gastric conduit following esophagectomy can be associated with an increased incidence of complications including aspiration pneumonia and anastomotic leak. The aim of this systematic review is to evaluate the current modalities of pyloric drainage following esophagectomy and their impact on anastomotic integrity and postoperative morbidity. Medline, Web of Science, Cochrane library, trial registries, and conference proceedings were searched. Five pyloric management strategies following esophagectomy were evaluated: no intervention, botulinum toxin (botox) injection, finger fracture, pyloroplasty, and pyloromyotomy. Outcomes evaluated were hospital mortality, anastomotic leak, pulmonary complications, delayed gastric emptying, and the late complication of bile reflux. Twenty-five publications comprising 3172 patients were analyzed. Pooled analysis of six comparative studies published after 2000 revealed pyloric drainage to be associated with a nonsignificant trend toward a reduced incidence of anastomotic leak, pulmonary complications, and delayed gastric emptying. Overall, the current level of evidence regarding the merits of individual pyloric drainage strategies remains very poor. There is significant heterogeneity in the definitions of clinical outcomes, in particular delayed gastric emptying, which has prevented meaningful assessment and formulation of consensus regarding the management of the pylorus during esophagectomy. Pyloric drainage procedures showed a non-significant trend toward fewer anastomotic leaks, pulmonary complications, and reduced gastric stasis when employed following esophagectomy. However, the ideal technique remains unproven suggesting that further collaborative investigations are needed to determine the intervention that will maximize the potential benefits, if any, of pyloric intervention.

Meta-Analysis Review
Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are the most commonly performed bariatric procedures globally, but both techniques have shortcomings. Several modifications of SG (SG plus procedures) have been developed, but the efficacy of the different procedures has not been completely elucidated. In this meta-analysis, we aimed to evaluate the efficacy and safety of SG plus procedures. Out of the initially identified 2357 studies, thirteen were selected for this meta-analysis: two studies on banded sleeve gastrectomy (BSG), four studies on sleeve gastrectomy plus duodenal-jejunal bypass (SG + DJB) or sleeve gastrectomy with loop duodenal-jejunal bypass (SADJB), two studies on sleeve gastrectomy with jejunal-jejunal bypass (SG + JJB), four studies on single anastomosis duodenal-ileal switch (SADI-S), and one study on stomach intestinal pylorus-sparing surgery (SIPS). SADI-S procedure was found to achieve significantly greater percentage of excess weight loss than the RYGB. SG + DJB and SADJB achieved greater weight loss than the RYGB. Major complications were fewer with SG + JJB than with RYGB, but the difference was not significant. Overall, SG plus procedures appear to achieve better weight loss and cause fewer complications than RYGB.

Meta-Analysis Review
BACKGROUND
Chronic pancreatitis (CP) is a common and frequently occurring disease. Pancreaticoduodenectomy (PD), pylorus-preserving pancreaticoduodenectomy (PPPD), and duodenum-preserving pancreatic head resection (DPPHR) are important treatment options for patients with chronic pancreatitis. The Beger and Frey procedures are 2 main duodenum-preserving techniques in duodenum-preserving pancreatic head resection (DPPHR) strategies. We conducted this systematic review and meta-analysis to compare the clinical efficacy of DPPHR versus PD, the Beger procedure versus PD, the Frey procedure versus PD, and the Beger procedure versus the Frey procedure in the treatment of pancreatitis. The optimal surgical option for chronic pancreatitis is still under debate. The aim of this systematic review and meta-analysis was to evaluate the clinical efficacy of different surgical strategies for chronic pancreatitis.
METHODS
Five databases (PubMed, Medline, SinoMed, Embase, and Cochrane Library) were searched with the limitations of human subjects and randomized controlled trials (RCTs) text. Data were extracted by 2 of the coauthors independently and analyzed using the RevMan statistical software, version 5.3. Weighted mean differences (WMDs), risk ratios (RRs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool was used to assess the risk of bias.
RESULTS
Seven studies involving a total of 385 patients who underwent the surgical treatments were assessed. The methodological quality of the trials ranged from low to moderate and included PD (n = 134) and DPPHR (n = 251 [Beger procedure = 100; Frey procedure = 109; Beger or Frey procedure = 42]). There were no significant differences between DPPHR and PD in post-operation mortality (RR = 2.89, 95% CI = 0.31-26.87, P = 0.36), pain relief (RR = 1.09, 95% CI = 0.94-1.25, P = 0.26), exocrine insufficiency (follow-up time > 60 months: RR = 0.91, 95% CI = 0.72-1.15, P = 0.41), and endocrine insufficiency (RR = 0.75, 95% CI = 0.52-1.08, P = 0.12). Concerning the follow-up time < 60 months, the DPPHR group had better results of exocrine insufficiency (RR = 0.22, 95% CI = 0.08-0.62, P = 0.04). However, operation time (P < 0.0001), blood transfusion (P = 0.02), hospital stay (P = 0.0002), postoperation morbidity (P = 0.0007), weight gain (P < 0.00001), quality of life (P = 0.01), and occupational rehabilitation (P = 0.007) were significantly better for patients who underwent the DPPHR procedure compared with the PD procedure. The comparison results of the Frey procedure and PD showed that both procedures had an equal effect in the pain relief, postoperation mortality, exocrine and endocrine function, and quality of life (QoL) (P > 0.05), whereas patients who underwent the Frey procedure had significantly reduced operative times (P < 0.05) and less blood transfusions (P < 0.05). Comparing the Beger procedure to the PD procedure, there were no significant differences in hospital stay, blood transfusion, postoperation morbidity or mortality, pain relief, weight gain, exocrine insufficiency, and occupational rehabilitation (P > 0.05). Two studies comparing the Beger and Frey procedures showed no differences in postoperative morbidity, pain relief, exocrine insufficiency, and quality of life (P > 0.05). In terms of operative time, blood transfusion, hospital stay, postoperation morbidity, weight gain, quality of life, and occupational rehabilitation, the results also favored duodenum-preserving pancreatic head resection (DPPHR) strategies.
CONCLUSION
All procedures are equally effective for the management of pain, postoperation morbidity, exocrine insufficiency, and endocrine insufficiency for chronic pancreatitis. Improved short- and long-term outcomes, including operative time, blood transfusion, hospital stay, quality of life, weight gain, and occupational rehabilitation make DPPHR a more favorable surgical strategy for patients with chronic pancreatitis. Further, relevant trails are eager to prove these findings.

Meta-Analysis
BACKGROUND
Patients should be informed beforehand of the risk factors for exocrine pancreatic insufficiency (ExoPI) after pancreatic surgery; however, there are no clear identified risk factors for this condition. This study aimed to identify the preoperative, perioperative and postoperative risk factors for ExoPI after pancreatic surgery.
METHODS
We conducted a systematic search of PubMed, Scopus, SAGE, CINAHL Plus and Taylor & Francis from inception to Mar. 7, 2021, for full-text articles that included patients who had undergone pancreatic surgery. The primary outcome was the number of ExoPI events and any risk factors evaluated. We used the Newcastle-Ottawa Scale to assess study quality.
RESULTS
Twenty studies involving 4131 patients (2312 [52.3%] male, mean age 60.12 [standard deviation 14.07] yr) were included. Of the 4131 patients, 1651 (40.0%) had postoperative ExoPI. Among the 11 factors evaluated, the significant risk factors were preoperative main pancreatic duct (MPD) diameter greater than 3 mm (odds ratio [OR] 4.50, 95% confidence interval [CI] 1.06-19.05), pancreaticoduodenectomy (PD) as the surgical treatment procedure (OR 3.31, 95% CI 1.92-5.68), pancreaticogastrostomy (PG) as the anastomotic procedure (OR 3.13, 95% CI 1.83-5.35), hard pancreatic texture (OR 2.93, 95% CI 1.99-4.32) and adjuvant chemotherapy (OR 2.50, 95% CI 1.54-4.04). Gender, history of diabetes mellitus or endocrine pancreatic insufficiency (EndoPI), underlying diseases, de novo diabetes or EndoPI, pylorus-preserving PD and postoperative pancreatic fistula were not risk factors for ExoPI after pancreatic surgery.
CONCLUSION
Preoperative MPD diameter greater than 3 mm, PD, PG reconstruction, hard pancreatic texture and adjuvant chemotherapy were risk factors for the development of ExoPI after pancreatic surgery. The findings should provide useful information for patients to reduce postoperative dissatisfaction and improve quality of life.

Review
Single-anastomosis duodenoileal bypass with sleeve gastrectomy/one anastomosis duodenal switch (SADI-S/OADS) was developed as a bariatric operation with reduced overall morbidity and lasting weight loss results. We performed a systematic review of the literature, including 14 studies reporting on weight loss, comorbidity resolution, postoperative complications, and nutritional deficiencies following SADI-S. Twelve months after SADI-S, the mean total body weight lost ranged from 21.5 to 41.2%, with no weight regain being observed after 24 months. The comorbidity resolution rate was 72.6% for diabetes, 77.2% for dyslipidemia, and 59.0% for hypertension cases. The need for reoperation was the most common postoperative complication. While several patients developed nutrient deficiencies, SADI-S seems to be an overall safe and effective bariatric operation.

INTRODUCTION
Infantile hypertrophic pyloric stenosis is treated by either open pyloromyotomy (OP) or laparoscopic pyloromyotomy (LP). The aim of this meta-analysis was to compare the open versus laparoscopic technique.
METHODS
A literature search was conducted from 1990 to February 2021 using the electronic databases MEDLINE, Embase, and Cochrane Central Register of Controlled Trials. Primary outcomes were mucosal perforation and incomplete pyloromyotomy. Secondary outcomes consisted of length of hospital stay, time to full feeds, operating time, postoperative wound infection/abscess, incisional hernia, hematoma/seroma formation, and death.
RESULTS
Seven randomized controlled trials including 720 patients (357 with OP and 363 with LP) were included. Mucosal perforation rate was not different between groups (relative risk [RR] LP versus OP 1.60 [0.49-5.26]). LP was associated with nonsignificant higher risk of incomplete pyloromyotomy (RR 7.37 [0.92-59.11]). There was no difference in neither postoperative wound infections after LP compared with OP (RR 0.59 [0.24-1.45]) nor in postoperative seroma/hematoma formation (RR 3.44 [0.39-30.43]) or occurrence of incisional hernias (RR 1.01 [0.11-9.53]). Length of hospital stay (-3.01 h for LP [-8.39 to 2.37 h]) and time to full feeds (-5.86 h for LP [-15.95 to 4.24 h]) were nonsignificantly shorter after LP. Operation time was almost identical between groups (+0.53 min for LP [-3.53 to 4.59 min]).
CONCLUSIONS
On a meta-level, there is no precise effect estimate indicating that LP carries a higher risk for mucosal perforation or incomplete pyloromyotomies compared with the open equivalent. Because of very low certainty of evidence, we do not know about the effect of the laparoscopic approach on postoperative wound infections, postoperative hematoma or seroma formation, incisional hernia occurrence, length of postoperative stay, time to full feeds, or operating time.

Review
The EndoFLIP system is a method of delineating impedance and was first designed to investigate the characteristics of the esophago-gastric junction. In the last decade, its use was widened to investigate other sphincteric and non-sphincteric systems of the gastrointestinal tract. The objective of the present systematic review was to summarize the available data in literature on the use of the EndoFLIP system in the gastrointestinal tract, including sphincteric and non-sphincteric regions. We performed a systematic review in accordance with recommendations for systematic review using PRISMA guidelines without date restriction, until June 2020, using MEDLINE-PubMed, Cochrane Library, and Google Scholar databases. Only articles written in English were included in the present review. Five hundred and six unique citations were identified from all database combined. Of those, 95 met the inclusion criteria. There was a lack of standardization among studies in terms of anesthetic drugs use, probe placement, and inflation protocol. In most cases, only small cohorts of patients were included. Most studies investigated the EGJ, with a potential use of the EndoFLIP to identify a subgroup of patients with achalasia and for intraoperative assessment of treatment efficacy in achalasia. However, the use of EndoFLIP in the esophageal body (esophageal panometry), other esophageal diseases (gastro-esophageal reflux disease, eosinophilic esophagitis), and other sphincter regions (anal canal, pylorus) will need further confirmatory studies. The EndoFLIP system provides detailed geometric data of the gastrointestinal lumen but further works are needed to determine its use in clinical practice.

Meta-Analysis
Clinical efficacy of gastric per-oral endoscopic myotomy (G-POEM) in the treatment of refractory gastroparesis and predictors of outcomes: a systematic review and meta-analysis using surgical pyloroplasty as a comparator group.
BACKGROUND AND AIMS
Gastric peroral endoscopic myotomy (G-POEM) is a novel minimally invasive technique in endosurgery. Data is limited as to its efficacy, safety, and predictive factors. We conducted this meta-analysis to evaluate the clinical outcomes of G-POEM and used the outcomes of surgical pyloroplasty as a comparator group in the treatment of refractory gastroparesis.
METHODS
We searched multiple databases from inception through March 2019 to identify studies that reported on G-POEM and pyloroplasty in gastroparesis. Our primary outcome was to analyze and compare the pooled rates of clinical success, in terms of Gastroparesis Cardinal Symptom Index (GCSI) score and 4-h gastric emptying study (GES) results, with G-POEM and pyloroplasty.
RESULTS
Three hundred and thirty-two and 375 patients underwent G-POEM (11 studies) and surgical pyloroplasty (seven studies), respectively. The pooled rate of clinical success, based on the GCSI score, with G-POEM was 75.8% (95% CI 68.1-82.1, I = 50) and with surgical pyloroplasty was 77.3% (95% CI 66.4-85.4, I = 0), with no significance, p = 0.81. The pooled rate of clinical success, based on the 4-hour GES results, with G-POEM was 85.1% (95% CI 68.9-93.7, I = 74) and with surgical pyloroplasty was 84% (95% CI 64.4-93.8, I = 81), with no significance, p = 0.91. The overall adverse events were comparable. Based on meta-regression analysis, idiopathic gastroparesis, prior treatment with botulinum toxin and gastric stimulator seemed to predict clinical success with G-POEM.
CONCLUSION
G-POEM demonstrates clinical success in treating refractory gastroparesis. Idiopathic gastroparesis, prior treatment with botulinum injections and gastric stimulator appear to have positive predictive effects on the 4-h GES results after G-POEM. Outcomes seem comparable to surgical pyloroplasty.

Meta-Analysis
PURPOSE
Surgical pyloroplasty or pyloromyotomy are often performed during esophagectomy with a view of improving gastric conduit drainage. However, the clinical importance of this is not clear, and some centers opt to omit this step. The aim of this meta-analysis is to compare the rates of pulmonary complications, anastomotic leak, mortality, delayed gastric emptying, and the need for further pyloric intervention, in patients undergoing esophagectomy with and without a drainage procedure.
METHODS
A database search of Medline, EMBASE, and Cochrane Library was performed to identify randomized control trials and cohort studies published between 2000 and 2020 which compared outcomes of esophagectomy with and without drainage procedures. A random-effects meta-analysis model was used to compare the rates of pulmonary complications, anastomotic leak, mortality, delayed gastric emptying, and the need for further pyloric intervention.
RESULTS
Three randomized and 12 non-randomized publications were identified, comprising a total of 2339 patients. No significant differences were found between the two groups with regard to pulmonary complications (RR 1.02 [95% CI, 0.78-1.33], p = 0.91), anastomotic leak (RR 1.14 [95% CI, 0.80-1.62], p = 0.48), mortality (RR 0.53 [95% CI, 0.23-1.26], p = 0.15), delayed gastric emptying (RR 0.98 [95% CI, 0.59-1.62], p = 0.93), and the need for further pyloric intervention (RR 1.99 [95% CI, 0.56-7.08], p = 0.29).
CONCLUSION
Where post-operative pyloric treatment is available on demand, surgical pyloric drainage procedures may not have any significant clinical impact on patient outcomes for patients undergoing esophagectomy, though further good-quality randomized controlled trials are needed to confirm this.
