Colon patch esophagoplasty for esophageal strictures refractory to multi-modal treatment revisited.

INTRODUCTION/PURPOSE: Esophageal strictures due to caustic ingestion (CI) may require repeat esophageal dilations and dilation adjuvants, including local anti-fibrinogenic injection therapy, stent placement, and radial stricture incisions. Refractory strictures require surgical intervention. Pedicled colon patch esophagoplasty (CPE) may avoid the morbidity associated with total esophageal replacement, although reports of its use are limited. Indications and outcomes for CPE in patients undergoing repeat esophageal stricture dilations following caustic ingestion are described according to our local experience and literature reports. MATERIALS AND METHODS: A retrospective review of indications for surgical management of esophageal strictures to tertiary pediatric surgical services between 2015 and 2020 focused on patients undergoing CPE. English-language literature (PubMed, Google Scholar, and Scopus) describing CPE was also reviewed. RESULTS: Eight (12%) out of 65 patients with esophageal strictures requiring 7 or more esophageal dilations with poor response underwent surgical stricture management over a 6 year period, which included stricture resection and re-anastomosis in 2 patients, total esophageal replacement with colon graft in 2 patients, gastric pull-up in 1 patient, and CPE in 3 patients. The patients undergoing CPE were aged 3-8 years and had 17 to more than 25 dilations following caustic ingestion over a 2-5 year period. One patient had a 4 cm stricture; the other 2 had strictures 7 cm in length. A transverse colon patch based on the middle and left colic vessels was utilized in all three, with the vascular pedicle placed retrogastrically via the esophageal hiatus and the patch inlay esophagoplasty concluded via right thoracotomy. Post-operative contrast studies showed near-normal anatomy, and the patients could tolerate full oral diets. During a 9-36 month follow-up period, only 2 patients required dilations of a proximal anastomotic stricture at 1 and 5 months postoperatively. One patient required additional proximal stricturoplasty with advancement of the original graft across the stricture via a cervical surgical approach. CONCLUSION: Colon patch esophagoplasty to restore esophageal luminal continuity and allow a normal diet should be considered for refractory esophageal strictures. CPE had excellent functional outcomes in our 3 patients and should be considered in selected cases instead of total esophageal replacement.

RESULTS OF PREVENTIVE METHODS OF OCCURRENCE CERVICAL ANASTOMOTIC COMPLICATIONS IN ESOPHAGOPLASTY.

OBJECTIVE: The aim: The aim of the study was to improve the results of surgical treatment in patients with corrosive esophageal strictures using the designed comprehensive surgical management program in esophagoplasty to decrease cervical anastomotic complications. PATIENTS AND METHODS: Materials and methods: The results of surgical treatment of 116 patients with esophageal strictures were studied. 45 patients had post-burn corrosive strictures, 17 - postoperative corrosive strictures, 10 - peptic strictures due to reflux esophagitis and 44 patients - esophageal cancer. All patients were divided into two groups: the control group, consisting of 55 patients who underwent conventional surgical treatment of corrosive esophageal strictures during 2005-2011, and experimental group involving 61 patients operated on during 2012- 2020, in whom an individual approach to the choice of surgical method was applied using diagnostic and treatment algorithm as well as the designed surgical management program. RESULTS: Results: In early postoperative period the proportion of specific and non-specific complications was significantly lower in experimental group as compared to the control group: cervical anastomotic leak - 16.36 % versus 4.392 %; strictures of cervical anastomosis - 20.0% versus 6.56 % (p<0.05). There were six postoperative deaths - four in the control group and two in experimental group. CONCLUSION: Conclusions: To prevent the development of cervical anastomotic complications and mortality in esophagoplasty proper therapeutic approach with consideration of all prognostic criteria and risk factors should be chosen and designed surgical management program should be applied.

Fundoplication in children with esophageal atresia: preoperative workup and outcome.

Up to 45% of esophageal atresia (EA) patients undergo fundoplication during childhood. Their esophageal dysmotility may predispose to worse fundoplication outcomes compared with patients without EA. We therefore compared fundoplication outcomes and symptoms pre- and post-fundoplication in EA patients with matched patients without EA. A retrospective review of patients with- and without EA who underwent a fundoplication was performed between 2006 and 2017. Therapeutic success was defined as complete sustained resolution of symptoms that were the reason to perform fundoplication. Fundoplication indications of 39 EA patients (49% male; median age 1.1 [0.1-17.0] yrs) and 39 non-EA patients (46% male; median age 1.3 [0.3-17.0] yrs) included respiratory symptoms, brief resolved unexplained events, typical symptoms of gastroesophageal reflux disease, recurrent strictures and respiratory problems. Post-fundoplication, therapeutic success was achieved in 5 (13%) EA patients versus 29 (74%) non-EA patients (P<0.001). Despite therapeutic success, all 5 (13%) EA patients developed postoperative sustained symptoms/complications versus 12 (31%) non-EA patients. Eleven (28%) EA patients versus 3 (8%) non-EA patients did not achieve any therapeutic success (P=0.036). Remaining patients achieved partial therapeutic success. EA patients suffered significantly more often from postoperative sustained dysphagia (41% vs. 13%; P=0.039), gagging (33% vs. 23%; P<0.001) and bloating (40% vs. 17%; P=0.022). Fundoplication outcomes in EA patients are poor and EA patients are more susceptible to post-fundoplication sustained symptoms and complications compared with patients without EA. The decision to perform fundoplication in EA patients with proven gastroesophageal reflux disease needs to be made with caution after thorough multidisciplinary evaluation.

Overlap method versus functional method for esophagojejunal reconstruction using totally laparoscopic total gastrectomy.

BACKGROUND: Laparoscopic intracorporeal esophagojejunostomy (EJ) is a useful method in totally laparoscopic total gastrectomy (TLTG) for treating upper-third gastric cancer. The two methods of laparoscopic intracorporeal EJ-functional and overlap-have not been compared side-by-side in terms of safety and feasibility. METHODS: Retrospective review and analysis of the data of 490 consecutive patients who underwent TLTG by either functional method (n = 365) or overlap (n = 125) method for upper- or middle-third gastric cancer was conducted between January, 2011 and May, 2018 at Asan Medical Center (Seoul, Korea). One-to-one propensity score matching (PSM) was performed to compare age, sex, body mass index, American Society of Anesthesiologist score, the presence of comorbidity, number of comorbidities, clinical T stage, clinical nodal stage, clinical TNM stage, history of previous abdominal surgery, and combined surgery. After PSM, 244 patients were divided into functional method group and overlap method group (n = 122, each). The surgical outcomes and EJ-related complications were compared between the two groups. RESULTS: No significant difference was found between the two groups in terms of early surgical outcomes such as operative time, time to first flatus, postoperative hospital stay, transfusion during surgery, transfusion after surgery, and administration of analgesics. However, the pain score was significantly lower in overlap method group (6.21 ± 1.83) than functional method group (6.97 ± 2.09, p < 0.05). The overlap method was also associated with significantly fewer late complications (3.28% vs. 12.30%; p < 0.05), lower Clavien-Dindo classification grade (p < 0.05), and fewer EJ-related complications (0.82% vs. 6.56%; p < 0.05), as compared with the functional method. CONCLUSION: The overlap method was safer and more feasible than the functional method for TLTG in gastric cancer patients, based on the finding of significantly lower incidence of EJ-related complications.

Evaluation of Gastroesophageal Reflux Disease 1 Year after Esophageal Atresia Repair: Paradigms Lost from a Single Snapshot?

OBJECTIVE: To analyze the findings of both multichannel intraluminal impedance with pH (MII-pH) and endoscopy/histopathology in children with esophageal atresia at age 1 year, according to current recommendations for the evaluation of gastroesophageal reflux disease (GERD) in esophageal atresia. STUDY DESIGN: We retrospectively reviewed both MII-pH and endoscopy/histopathology performed in 1-year-old children with esophageal atresia who were followed up in accordance with international recommendations. Demographic data and clinical characteristics were also reviewed to investigate factors associated with abnormal GERD investigations. RESULTS: In our study cohort of 48 children with esophageal atresia, microscopic esophagitis was found in 33 (69%) and pathological esophageal acid exposure on MII-pH was detected in 12 (25%). Among baseline variables, only the presence of long-gap esophageal atresia was associated with abnormal MII-pH. Distal baseline impedance was significantly lower in patients with microscopic esophagitis, and it showed a very good diagnostic performance in predicting histological changes. CONCLUSIONS: Histological esophagitis is highly prevalent at 1 year after esophageal atresia repair, but our results do not support a definitive causative role of acid-induced GERD. Instead, they support the hypothesis that chronic stasis in the dysmotile esophagus might lead to histological changes. MII-pH may be a helpful tool in selecting patients who need closer endoscopic surveillance and/or benefit from acid suppression.

How to ensure immediate and long-term good blood supply by the careful dissection of the marginal artery and supercharge with neck vessels in esophageal reconstruction with the colon segment interposition: 35 years of experience.

BACKGROUND: Colon interposition for total esophageal replacement cases represents one of the most challenging procedures in surgery. A retrospective study has been conducted and suggestions are proposed according to the analysis of 268 patients who underwent colon interposition for esophageal replacement. Complication rates and the duration of hospital stay were retrospectively analyzed. METHODS: A total of 268 patients were operated between 1984 and 2018. In group 1, 164 patients underwent colon interposition without supercharging with neck vessels and in group 2, 104 patients underwent colon interposition with supercharging. Data regarding flap loss, anastomotic leakage, the duration of hospital stay, and stricture formation in the long-term were statistically analyzed and compared between two groups. RESULTS: The success rate of reconstruction was 98,1% (161 of 164 patients) and 99% (103 of 104 patients) for group 1 and 2, respectively. Early complication (anastomotic leakage) rate was 4,9% in group 1 and 1% in group 2. The differences between two groups regarding flap loss and anastomotic leakage rates were not statistically significant (p = 0,495 and p = 0,077, respectively). The hospital stay was 26,3 days for patients without supercharging (group1) and 20,5 days for patients with supercharging (group 2). In group 1, 6,7% (11/164) of patients had narrowing at the junction of the pharynx and colon; however, in group 2, proximal anastomotic stricture formation was observed in only 1% (1/104) of the patients. The stricture rate was significantly lower in group 2 when compared to group 1 (p = 0,021). CONCLUSION: The careful dissection of the marginal artery and supercharging with neck vessels provide lower complication rates in colon interposition for esophageal reconstruction.

MODERN METHODS OF PREVENTION AND TREATMENT OF COMPLICATIONS OF CERVICAL ESOPHAGO-ORGAN ANASTOMOSIS AT ESOPHAGOPLASTY.

OBJECTIVE: The aim: To improve the results of operative treatment of esophageal strictures by decreasing the rate of failure and stricture of cervical esophago-organ anastomoses. PATIENTS AND METHODS: Materials and methods: There were 45 patients with post-burn corrosive gullet strictures, 17 patients with postoperative corrosive strictures, 10 patients with peptic strictures secondary to reflux-esophagitis, 42 patients with esophageal cancer strictures. The patients were divided into two groups: the comparison group - 55 persons and the main group - 59 persons. Patients of comparison group underwent surgical treatment of esophageal strictures according to classic protocols and standards. In the main group of patients we applied proposed diagnostic algorithm with prediction of complication risk and the designed method of esophago-organ anastomosis formation. RESULTS: Results: The results of operative treatment in patients with esophageal strictures showed the development of early postoperative complications in 59 individuals (51.75 %). In the postoperative period six patients died: four - in the comparison group and two - in the main group. Failure of cervical esophago-organ anastomosis and esophageal strictures occurred in 7 patients (11.86 %) of main group and 20 patients (36.36 %) of the comparison group (p<0.05). CONCLUSION: Conclusions: Application of method predicting the risk of complications of cervical anastomosis, treatment program and instrumental method of formation anastomosis resulted in reduced incidence of failure and strictures of esophago-organ anastomosis from 36.36 % to 11.86 % (p<0.05); decreased time of hospitalization - from 28.2 ± 1.1 to 21.5 ± 0.5 bed-days (p<0.001), postoperative period - from 20.5 ± 1.1 to 16.1 ± 0.7 bed-days (p<0.01); decreased postoperative mortality - from 7.27 % to 3.39 %.

30-Day Outcomes Following Esophageal Replacement in Children: A National Surgical Quality Improvement Project Pediatric Analysis.

INTRODUCTION: The optimal method of esophageal replacement remains controversial. The aim of this study was to evaluate 30-d outcomes of children in the National Surgical Quality Improvement Project Pediatric (NSQIP-P) database who underwent esophageal replacement from 2012 to 2018. METHODS: Demographics, comorbidities, and procedural technique was identified in NSQIP-P and reviewed. Thirty-day outcomes were assessed and stratified by gastric pull-up or tube interposition versus small bowel or colonic interposition. Categorical and continuous variables were assessed by Pearson's chi-square, Fisher's exact, and Wilcoxon rank-sum tests, respectively. Multivariate logistic regression was performed to estimate the effects of procedure technique and clinical risk factors on patient outcomes. RESULTS: Of the 99 cases of esophageal replacement included, 52 (52.5%) utilized a gastric conduit, whereas 47 (47.5%) involved small bowel/colonic esophageal interposition. Overall risk of complications was 52.5%, the most common of which were perioperative transfusion (30.3%), surgical site infection (11.1%), and sepsis (9.1%). Risk of unplanned reoperation was 17.2%, and risk of mortality was 3.0%. Risk for complications, reoperation, and readmission did not differ significantly between those who underwent gastric esophageal replacement and those who underwent small bowel or colonic interposition. Median operative time was shorter in the gastric esophageal replacement group (5.2 versus 8.1 h, P = 0.009). CONCLUSIONS: Among children in NSQIP-P who underwent esophageal replacement from 2012 to 2018, the risk of 30-d complications, unplanned reoperation, and mortality was relatively frequent and was similar across operative techniques. Opportunities exist to improve preoperative optimization, utilization of blood transfusion services, and infectious complications in the perioperative period irrespective of operative technique. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Laparoscopic Heller Myotomy and Dor Fundoplication: How I Do It?

Achalasia is a primary esophageal motility disorder characterized by lack of esophageal peristalsis and partial or absent relaxation of the lower esophageal sphincter in response to swallowing. Available treatment modalities are not curative but rather intend to relieve patient' symptoms. A laparoscopic Heller myotomy with Dor fundoplication is associated with high clinical success rates and low incidence of postoperative reflux. A properly executed operation following critical surgical steps is key for the success of the operation.

Reduced anastomotic complications with intracorporeal esophagojejunostomy using endoscopic linear staplers (overlap method) in laparoscopic total gastrectomy for gastric carcinoma.

BACKGROUND: With advances in surgical technique and instrumentation, intracorporeal anastomosis is increasingly being performed for laparoscopic total gastrectomy (LTG). However, the benefits of intracorporeal anastomosis in reducing postoperative complications have not been demonstrated, although its technical feasibility has been proven in many studies. In this study, we investigated the impact of intracorporeal anastomosis in reducing postoperative complications after LTG. METHODS: We analyzed 410 consecutive gastric cancer patients who underwent LTG between 2008 and 2018. Of these, 118 underwent intracorporeal anastomosis using linear staplers (overlap method), while 292 underwent extracorporeal anastomosis using a circular stapler. Short-term surgical outcomes including postoperative complications were compared between the two groups. RESULTS: The two groups showed no significant differences in age, sex, comorbidity, and abdominal surgery history. D2 lymph node dissection was more frequently performed in the intracorporeal group because of the presence of more advanced cancer stages. The overall morbidity in the intracorporeal and extracorporeal group was 23.7% and 27.7%, respectively (p = 0.405). However, the intracorporeal group showed a significantly lower incidence of late complications (0.8% vs. 7.5%, p = 0.008). Concerning complications, the incidence of anastomotic bleeding (0% vs. 5.5%, p = 0.008) and anastomotic stenosis (0% vs. 4.5%, p = 0.024) was significantly lower in the intracorporeal group. In univariate and multivariate analyses, American Society of Anesthesiologists score and operative bleeding were independent predictive factors for postoperative complications in patients who underwent intracorporeal anastomosis. CONCLUSIONS: Intracorporeal anastomosis using linear staplers reduced anastomotic bleeding and stenosis compared to extracorporeal anastomosis after LTG. Future research will be required to determine the ideal method for intracorporeal anastomosis in LTG.

Surgical treatment and major complications Within the first year of life in newborns with long-gap esophageal atresia gross type A and B - a systematic review.

BACKGROUND: The surgical repair of long-gap esophageal atresia (LGEA) is still a challenge and there is no consensus on the preferred method of reconstruction. We performed a systematic review of the surgical treatment of LGEA Gross type A and B with the primary aim to compare the postoperative complications related to the different methods within the first postoperative year. METHODS: Systematic literature review on the surgical repair of LGEA Gross type A and B within the first year of life published from January 01, 1996 to November 01, 2016. RESULTS: We included 57 articles involving a total of 326 patients of whom 289 had a Gross type A LGEA. Delayed primary anastomosis (DPA) was the most applied surgical method (68.4%) in both types, followed by gastric pull-up (GPU) (8.3%). Anastomotic stricture (53.7%), gastro-esophageal reflux (GER) (32.2%) and anastomotic leakage (22.7%) were the most common postoperative complications, with stricture and GER occurring more often after DPA (61.9% and 40.8% respectively) compared to other methods (p < 0.001). CONCLUSION: The majority of patients in this review were managed by DPA and postoperative complications were common despite the surgical method, with anastomotic stricture and GER being most common after DPA. LEVEL OF EVIDENCE: Systematic review of case series and case reports with no comparison group (level IV).

Stenosis of the celiac trunk is associated with anastomotic leak after Ivor-Lewis esophagectomy.

Transthoracic esophagectomy with gastric tube formation is the surgical treatment of choice for esophageal cancer. The surgical reconstruction induces changes of gastric microcirculation, which are recognized as potential risk factors of anastomotic leak. This prospective observational study investigates the association of celiac trunk (TC) stenosis with postoperative anastomotic leak. One hundred fifty-four consecutive patients with esophageal cancer scheduled for Ivor-Lewis esophagectomy were included. Preoperative staging computed tomography (CT) was used to identify TC stenosis. Any narrowing of the lumen due to atherosclerotic changes was classified as stenosis. Percentage of stenotic changes was calculated using the North American Symptomatic Carotid Endarterectomy Trial formula. Multivariable analysis was used to identify possible risk factors for leak. The overall incidence of TC stenosis was 40.9%. Anastomotic leak was identified in 15 patients (9.7%). Incidence of anastomotic leak in patients with stenosis was 19.4% compared to 2.3% in patients without stenosis. Incidence of stenosis in patients with leak was 86.7% (13 of 15 patients) and significantly higher than 38.8% (54 of 139 patients) in patients without leak (P < 0.001). There was a significant difference in median degree of TC stenosis (50.0% vs 39.4%; P = 0.032) in patients with and without leak. In the multivariable model, TC stenosis was an independent risk factor for anastomotic leak (odds ratio: 5.98, 95% CI: 1.58-22.61). TC stenosis is associated with postoperative anastomotic leak after Ivor-Lewis esophagectomy. Routine assessment of TC for possible stenosis is recommended to identify patients at risk.

Investigating rates of reoperation or postsurgical gastroparesis following fundoplication or paraesophageal hernia repair in New York State.

BACKGROUND: Little is known of the natural history of fundoplication or paraesophageal hernia (PEH) repair in terms of reoperation or the incidence treatment of postsurgical gastroparesis (PSG) in large series. Repeat fundoplications or PEH repairs, as well as pyloroplasty/pyloromyotomy operations, have proven to be effective in the context of PSG or recurrence. In this study, we analyzed the incidences of PSG and risk factors for these revisional surgeries following fundoplication and PEH repair procedures in the state of New York. METHODS: The New York State Planning and Research Cooperative System (NY SPARCS) database was utilized to examine all adult patients who underwent fundoplication or PEH repair for the treatment of GERD between 2005 and 2010. The primary outcome was the incidence of each type of reoperation and the timing of the follow-up procedure/diagnosis of gastroparesis. Generalized linear mixed models were used to examine the risk factors for follow-up procedures/diagnosis. RESULTS: A total of 5656 patients were analyzed, as 3512 (62.1%) patients underwent a primary fundoplication procedure and 2144 (37.9%) patients underwent a primary PEH repair. The majority of subsequent procedures (n = 254, 65.5%) were revisional procedures (revisional fundoplication or PEH repair) following a primary fundoplication. A total of 134 (3.8%) patients who underwent a primary fundoplication later had a diagnosis of gastroparesis or a follow-up procedure to treat gastroparesis, while 95 (4.4%) patients who underwent a primary PEH repair were later diagnosed with gastroparesis or underwent surgical treatment of gastroparesis. CONCLUSION: The results revealed low reoperation rates following both fundoplication and PEH repairs, with no significant difference between the two groups. Additionally, PEH repair patients tended to be older and were more likely to have a comorbidity compared to fundoplication patients, particularly in the setting of hypertension, obesity, and fluid and electrolyte disorders. Further research is warranted to better understand these findings.

Surgical repair of long-gap esophageal atresia: A retrospective study comparing the management of long-gap esophageal atresia in the Nordic countries.

BACKGROUND: Several surgical procedures have been described in the reconstruction of long-gap esophageal atresia (LGEA). We reviewed the surgical methods used in children with LGEA in the Nordic countries over a 15-year period and the postoperative complications within the first postoperative year. METHODS: Retrospective multicenter medical record review of all children born with Gross type A or B esophageal atresia between 01/01/2000 and 12/31/2014 reconstructed within their first year of life. RESULTS: We included 71 children; 56 had Gross type A and 15 type B LGEA. Delayed primary anastomosis (DPA) was performed in 52.1% and an esophageal replacement procedure in 47.9%. Gastric pull-up (GPU) was the most frequent procedure (25.4%). The frequency of chromosomal abnormalities, congenital heart defects and other anomalies was significantly higher in patients who had a replacement procedure. The frequency of gastroesophageal reflux (GER) was significantly higher after DPA compared to esophageal replacement (p = 0.013). At 1-year follow-up the mean body weight was higher after DPA than after organ interposition (p = 0.043). CONCLUSION: DPA and esophageal replacement procedures were equally applied. Postoperative complications and follow-up were similar except for the development of GER and the body weight at 1-year follow-up. Long-term results should be investigated. TYPE OF STUDY: Treatment study. LEVEL OF EVIDENCE: Level III.

Suture fistula revisited for long gap esophageal atresia.

BACKGROUND: Long gap esophageal atresia presents a challenge to pediatric surgeons due to the variability in surgical management when primary anastomosis is not feasible. Mechanical traction procedures enhance tissue growth that allows early anastomosis, before delayed primary closure (DPC) would be attempted to allow for rapid oral feeding, or when operative discoveries require flexibility of the surgical plan. The Suture Fistula procedure, first published by Alan Shafer and Tirone David in 1974, is a simple, effective, but underutilized single-stage procedure which results in spontaneous fistulization of approximated, non-anastomosed esophageal segments using tension sutures. METHODS: A retrospective chart review was performed of patients who underwent the Suture Fistula procedure at a single institution since 1992. A literature review of all published case series of patients who underwent this procedure was also performed. RESULTS: There were 5 case series found with a total of 24 patients, and three new cases presented. Patients were noted to have spontaneous fistulization with gastrostomy tube feed reflux noted in the upper esophagus or mouth on average of post-operative day 14, which occurred in over 85% of patients. While nearly all patients required esophageal dilation and anti-reflux procedures, the morbidity of the procedure, including esophageal leak, is very low, and similar to the Foker or Kimura procedures, which have been more popular despite their surgical complexity. CONCLUSION: We propose the Suture Fistula technique to be a simpler, more effective, and safe alternative to other mechanical traction suture procedures in cases where primary anastomosis is not feasible. LEVEL OF EVIDENCE: Level IV.

Operative treatment of corrosive esophageal strictures.

OBJECTIVE: Introduction: Nowadays operative treatment of corrosive esophageal strictures remains one of the difficult and unsolved problems in surgery. The level of postoperative complications such as anastomotic leak (develops in 7-30% of cases), infections, pneumonia, pleural empyema, mediastinitis, peritonitis, postoperative corrosive strictures is still rather high. The aim of our work was to improve the results of surgical treatment of patients with corrosive esophageal strictures by analyzing and refining on conservative therapy options as well as differentiated approach to each operative treatment method. PATIENTS AND METHODS: Materials and methods: 44 patients with corrosive esophageal strictures operatively treated during the period of 1993-2017 were examined. Indications for each of esophagoplasty techniques were established. In colon bypass of the esophagus (26 patients) infusion therapy for prevention of ischemic transplant disorders, roentgenologic and prevascular preparation of future colonic transplant, anti-reflux colonogastric anastomosis were suggested. In gastric esophagoplasty (10 patients), clinically modified transhiatal extirpation of the esophagus with gastric tube plastics, an original method of lengthening of gastric graft, is preferred in clinical practice. Two patients underwent ileocecal segment esophagoplasty because of simultaneous esophageal and gastric lesion or colon diseases. RESULTS: Results: The best method of esophagoplasty associated with a small number of postoperative complications is clinically modified gastric tube esophagoplasty with formation of single extrapleural esophagogastric anastomosis. In cases when the stomach cannot be used and the marginal artery is well marked, isoperistaltic retrosternal colonoplasty with preservation of blood supply due to the left colonic artery is indicated. Suggested method of ileocecal segment esophagoplasty is used in simultaneous esophageal and gastric lesion, providing the formation of relevant reservoir (the cecum instead of the stomach), antireflux mechanism and preventing the development of peptic ulcers and transplant strictures. CONCLUSION: Conclusions: Operative treatment of corrosive esophageal strictures remains a great challenge for surgeons and should be based on individual choice of proper method of esophagoplasty and final intraoperative decision making.

Are prophylactic anti-reflux medications effective after esophageal atresia repair? Systematic review and meta-analysis.

PURPOSE: Gastroesophageal reflux after surgical repair of esophageal atresia (EA) can be associated with complications, such as esophageal stricture. Recent guidelines recommend prophylactic anti-reflux medication (PARM) after EA repair. However, the effectiveness of PARM is still unclear. The aim of this study was to review evidence surrounding the use of PARM in children operated for EA. METHODS: We performed a systematic review and meta-analysis. We searched Medline, EMBASE, and the Cochrane Databases from inception until the end of 2016 for comparative studies of PARM versus no PARM (control). Primary outcome was postoperative esophageal stricture. Quality of evidence was assessed using GRADE system. RESULTS: We identified four observational studies that focused on esophageal stricture as an outcome. A total of 362 patients were included in meta-analysis. There was no significant difference in esophageal stricture rates between PARM and control (OR = 1.14; 95% CI = 0.61-2.13; p = 0.68; I2 = 38%). The quality of the evidence was very low, due to lack of precision as a consequence of small study sizes. CONCLUSIONS: Our results indicate that PARM does not reduce the incidence of esophageal stricture after EA repair. Future well-controlled prospective studies are needed to obtain higher quality evidence.

[Efficacy of serosomyotomy in esophagogastroplasty]. / Éffektivnost' serozomiotomii pri ézofagogastroplastike.

AIM: To evaluate an effectiveness of serosomyotomy in isoperistaltic esophagogastroplasty. MATERIAL AND METHODS: Our analysis shows that serosomyotomy improves the results of isoperistaltic esophagogastroplasty. RESULTS: Esophagogastrostomy by using of proximal graft with adequate blood supply reduced the risk of anastomosis failure. The incidence of this complication was 12.2% (n=6) and 3% (n=1) in control and main groups respectively.
