Abstract
This systematic review and meta-analysis aimed to investigate the incidence of new-onset gastroesophageal reflux, reflux change, esophagitis, Barrett's esophagus, and revision due to reflux, gastritis, and marginal ulcer after one-anastomosis gastric bypass (OAGB). We performed subgroup analyses based on primary and revisional OAGB and time of follow-up. Meta-analysis of 87 studies with 27,775 patients showed a 6% rate of new-onset reflux after OAGB. Preoperative reflux status did not change significantly after OAGB. The rate of esophagitis and Barrett's esophagus was 15% and 1%, respectively. The new-onset reflux rate after OAGB was significantly higher than gastric bypass but not different with sleeve gastrectomy. The current study showed a relatively low rate of reflux and its complications after OAGB, but it was significantly higher than Roux-en-Y gastric bypass.

Applying an Anti-reflux Suture in the One Anastomosis Gastric Bypass to Prevent Biliary Reflux: a Long-Term Observational Study. Obes Surg 2021; 31:2144-2152. [PMID: 33496931 DOI: 10.1007/s11695-021-05238-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2020] [Revised: 01/14/2021] [Accepted: 01/14/2021] [Indexed: 12/11/2022]
Abstract
INTRODUCTION The one anastomosis gastric bypass (OAGB) is an effective treatment to induce sustained weight loss in morbidly obese patients. Concerns remain regarding the development of reflux. The aim of this study was to investigate the effect of an "anti-reflux suture" as anti-reflux modification to prevent reflux. METHOD This is a single-center retrospective cohort study of patients who underwent a primary OAGB at the Center Obesity North-Netherlands (CON) between January 2015 and December 2016. Reflux was defined as symptoms of acid/bilious regurgitation or pyrosis. This was consequently asked and reported at each follow-up visit. Outcomes of patients with an anti-reflux suture were compared to those without. RESULTS In 414 (59%) of the 703 included patients, an anti-reflux suture was applied. Follow-up at 3 years was 74%. The incidence of reflux did not differ between patients with or without an anti-reflux suture (57 versus 56%, respectively; P = 0.9). The presence of an anti-reflux suture was significantly associated with a lower incidence of conversion to Roux-en-Y gastric bypass (RYGB) for reflux (OR 0.56, 95%CI 0.34-0.91). Patients preoperatively diagnosed with gastroesophageal reflux disease (GERD) were 5.2 times more likely to need a conversion to RYGB for reflux (95%CI 2.7-10.1). CONCLUSION The presence of preoperative GERD should be weighted heavily in the decision to perform an OAGB as this is a major risk factor for conversion surgery due to reflux. The anti-reflux suture might be a valuable addition to the procedure of the OAGB because it results in fewer conversion surgeries for reflux.

Esophagogastric junction function and gastric pressure profile after minigastric bypass compared with Billroth II. Surg Obes Relat Dis 2019; 15:567-574. [PMID: 30827811 DOI: 10.1016/j.soard.2019.01.030] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 01/03/2019] [Accepted: 01/31/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Minigastric bypass (MGB) is being performed widely with effective weight loss and improvement in co-morbidities. Because of similarity to Billroth II (BII), there are concerns about bile reflux. OBJECTIVES To assess the esophagogastric junction (EGJ) function, esophageal peristalsis, and reflux exposure after MGB and BII. SETTING University Hospital, Italy; Public Hospital, Italy. METHODS Obese patients underwent symptom questioning, endoscopy, high-resolution impedance manometry, and impedance-pH monitoring, before and 1 year after MGB. Esophageal motor function, EGJ, EGJ-contractile integral, intragastric pressure (IGP), and gastroesophageal pressure gradient were determined. Acid exposure time, number of refluxes, and symptom-association probability were assessed. A group of patients who underwent BII were studied with the same protocol and served as controls. RESULTS Twenty-two MGB and 20 BII patients were studied. After surgery, none of the patients reported de novo heartburn or regurgitation. At endoscopic follow-up, esophagitis and bile findings were absent in all. High-resolution impedance manometry features did not vary significantly after MGB, whereas IGP and gastroesophageal pressure gradient statistically diminished (P < .01). BII patients had significantly lower values in IGP, sphincter pressure, and EGJ-contractile integral. In MGB patients, a marked decrease in number of refluxes (from median 41 to 7, P < .01) was observed, whereas BII patients had statistically significant higher acid exposure and number of refluxes (57, P < .001). CONCLUSIONS In contrast to BII, MGB does not increase any kind of reflux. Also, the differences in IGP and gastroesophageal pressure gradient suggest that bile reflux occurs more readily after BII than after MGB, and that these 2 operations share more differences than similarities.

Abstract
Experimental reproduction of duodeno-gastric reflux was performed among Wistar line 28 rats, which were injected with 50 % solution of medical bile by intragastric way. Morphological study had been shown significant structural changes in the gingival tissues, mucous membrane of an esophagus, stomach and duodenum. In the epithelial layer of gingiva and esophagus was observed numerous infringements in a process of differentiation cells, in the stroma was shown phenomena of fibrosis in a papillary layer, microcirculation disorders. In the gastric mucosa had been found out multiple erosions, the glandular cells were increased. It was demonstrated vacuolization of the basal and thorn layers of the stomach epithelium. In the stroma defined phenomena of fibrosis and a dense lymphocyte infiltration with eosinophils. In the duodenum was determined desquamation of a glandular epithelium, superficial erosions of the villi, lympho–histio–plasmocytosis infiltration in a stroma, microvascular disorders. The given experiment demonstrates a role of functional disorders in the pathogenesis of combined pathology in the upper gastrointestinal tract.

Abstract
BACKGROUND Excellent results have been reported with mini-gastric bypass. We adopted and modified the one-anastomosis gastric bypass (OAGB) concept. Herein is our approach, results, and long-term follow-up (FU). METHODS Initial 1200 patients submitted to laparoscopic OAGB between 2002 and 2008 were analyzed after a 6-12-year FU. Mean age was 43 years (12-74) and body mass index (BMI) 46 kg/m2 (33-86). There were 697 (58 %) without previous or simultaneous abdominal operations, 273 (23 %) with previous, 203 (17 %) with simultaneous, and 27 (2 %) performed as revisions. RESULTS Mean operating time (min) was as follows: (a) primary procedure, 86 (45-180); (b) with other operations, 112 (95-230); and (c) revisions, 180 (130-240). Intraoperative complications led to 4 (0.3 %) conversions. Complications prompted operations in 16 (1.3 %) and were solved conservatively in 12 (1 %). Long-term complications occurred in 12 (1 %). There were 2 (0.16 %) deaths. Thirty-day and late readmission rates were 0.8 and 1 %. Cumulative FU was 87 and 70 % at 6 and 12 years. The highest mean percent excess weight loss was 88 % (at 2 years), then 77 and 70 %, 6 and 12 years postoperatively. Mean BMI (kg/m2) decreased from 46 to 26.6 and was 28.5 and 29.9 at those time frames. Remission or improvement of comorbidities was achieved in most patients. The quality of life index was satisfactory in all parameters from 6 months onwards. CONCLUSIONS Laparoscopic OAGB is safe and effective. It reduces difficulty, operating time, and early and late complications of Roux-en-Y gastric bypass. Long-term weight loss, resolution of comorbidities, and degree of satisfaction are similar to results obtained with more aggressive and complex techniques. It is currently a robust and powerful alternative in bariatric surgery.

Abstract
BACKGROUND At present, no objective data are available on the effect of omega-loop gastric bypass (OGB) on gastroesophageal junction and reflux. OBJECTIVES To evaluate the possible effects of OGB on esophageal motor function and a possible increase in gastroesophageal reflux. SETTING University Hospital, Italy; Public Hospital, Italy. METHODS Patients underwent clinical assessment for reflux symptoms, and endoscopy plus high-resolution impedance manometry (HRiM) and 24-hour pH-impedance monitoring (MII-pH) before and 1 year after OGB. A group of obese patients who underwent sleeve gastrectomy (SG) were included as the control population. RESULTS Fifteen OGB patients were included in the study. After surgery, none of the patients reported de novo heartburn or regurgitation. At endoscopic follow-up 1 year after surgery, esophagitis was absent in all patients and no biliary gastritis or presence of bile was recorded. Manometric features and patterns did not vary significantly after surgery, whereas intragastric pressures (IGP) and gastroesophageal pressure gradient (GEPG) statistically diminished (from a median of 15 to 9.5, P<.01, and from 10.3 to 6.4, P<.01, respectively) after OGB. In contrast, SG induced a significant elevation in both parameters (from a median of 14.8 to 18.8, P<.01, and from 10.1 to 13.1, P<.01, respectively). A dramatic decrease in the number of reflux events (from a median of 41 to 7; P<.01) was observed after OGB, whereas in patients who underwent SG a significant increase in esophageal acid exposure and number of reflux episodes (from a median of 33 to 53; P<.01) was noted. CONCLUSIONS In contrast to SG, OGB did not compromise the gastroesophageal junction function and did not increase gastroesophageal reflux, which was explained by the lack of increased IGP and in GEPG as assessed by HRiM.

Abstract
Mini gastric bypass is a modification of Mason loop gastric bypass with a longer lesser curvature-based pouch. Though it has been around for more than 15 years, its uptake by the bariatric community has been relatively slow, and the procedure has been mired in controversy right from its early days. Lately, there seems to be a surge in the interest in this procedure, and there is now published experience with more than 5,000 procedures globally. This review examines the major controversial aspects of this procedure against the available scientific literature. Surgeons performing this procedure need to be aware of these controversies and counsel their patients appropriately.

Abstract
AIM The aim of this study was to investigate the role of bile and acid reflux in the pathogenesis of reflux oesophagitis (RE) in children. METHODS A total of 44 patients aged 5-17 years with gastro-oesophageal reflux symptoms were enrolled. Simultaneous 24-h oesophageal Bilitec 2000 (Medtronic Instruments, Minneapolis, MN, USA) bilirubin monitoring and pH monitoring, in biopsy of oesophageal mucosa by gastro-endoscopy, were performed in all patients. RESULTS According to the diagnostic criteria of pathological acid reflux and pathological bile reflux, 10 of 44 cases (22.7%) had acid reflux, 10 (22.7%) had isolated bile reflux, 16 (36.4%) had mixed acid and bile reflux, and the other eight (18.2%) had no reflux. Significant difference was observed in the ratio of different patterns of reflux between the RE group (26 cases) and the non-erosive reflux disease (NERD) group (18 cases) (chi(2) = 9.096, P < 0.01). All the parameters of acid reflux in the RE group were higher significantly than that in the NERD group (P < 0.05 or P < 0.01). A total of 20 out of 26 cases (76.9%) with RE had oesophageal acid reflux as against six out of 18 cases (33.3%) in patients with NERD (P < 0.01). The difference of each parameter of bile reflux had not reached significance between the two groups. CONCLUSIONS Mixed reflux is the predominant form of reflux in the causation of oesophageal mucosal injury in children. Isolated bile reflux also plays a role in the development of RE, although only in patients without acid reflux.

Abstract
AIM: To investigate the hypothesis that duodeno-jejunal dyssynergia existed at the duodeno-jejunal junction.
METHODS: Of 112 patients who complained of epigastric distension and discomfort after meals, we encountered nine patients in whom the duodeno-jejunal junction did not open on duodenal contraction. Seven healthy volunteers were included in the study. A condom which was inserted into the 1st duodenum was filled up to 10 mL with saline in increments of 2 mL and pressure response to duodenal distension was recorded from the duodenum, duodeno-jejunal junction and the jejunum.
RESULTS: In healthy volunteers, duodenal distension with 2 and 4 mL did not produce pressure changes, while 6 and up to 10 mL distension effected significant duodenal pressure increase, duodeno-jejunal junction pressure decrease but no jejunal pressure change. In patients, resting pressure and duodeno-jejunal junction and jejunal pressure response to 2 and 4 mL duodenal distension were similar to those of healthy volunteers. Six and up to 10 mL 1st duodenal distension produced significant duodenal and duodeno-jejunal junction pressure increase and no jejunal pressure change.
CONCLUSION: Duodeno-jejunal junction failed to open on duodenal contraction, a condition we call ‘duodeno-jejunal junction dyssynergia syndrome’ which probably leads to stagnation of chyme in the duodenum and explains patients' manifestations.

Abstract
OBJECTIVE To assess the long-term results of the duodenal switch operation made for pathologic transpyloric duodenogastric reflux (DGR). SUMMARY BACKGROUND DATA DGR symptoms and lesions are poorly responsive to medical treatment. METHODS A duodenal switch operation was made on 48 patients suffering from pathologic transpyloric DGR either unrelated (n = 28) or secondary (n = 20) to previous upper gastrointestinal (GI) surgery, including cholecystectomy or vagotomy. The diagnosis was based on the combination of several objective arguments: a long history of gastric symptoms (ie, nausea, epigastric pain, and/or bilious vomiting) poorly responsive to medical treatment (48 of 48), gastroesophageal reflux symptoms unresponsive to proton-pump inhibitors (PPI) (23 of 29), gastritis on upper GI endoscopy (37 of 48) and/or at histology (28 of 41), presence of a bilious gastric lake at >1 upper GI endoscopy (30 of 48), DGR at diisopropyl iminodiacetic acid (DISIDA) scintigraphy scanning (7 of 13), pathologic 24-hour intragastric bile monitoring with the Bilitec device (40 of 41), and absence of Helicobacter pylori antral infection (39 of 41). RESULTS At follow-up (median, 81 months), gastric symptoms were nil, had improved, and remained unchanged in 29 (60.4%), 16 (33.3%), and 2(4.2%) patients, respectively, and 1 patient experienced symptomatic recurrence after a 92-month symptom-free period (2.1%). Among the 44 patients who had postoperative upper GI endoscopy, 42 (95.5%) had no gastritis whereas 5 (11.3%) had an ulcer at the duodenojejunostomy. Gastric exposure to bile at postoperative 24-hour intragastric Bilitec test in 36 patients was nil, within the normal range, and still slightly pathologic in 15 (41.7%), 19 (52.8%), and 2 (5.5%), respectively. CONCLUSIONS The duodenal switch operation made on patients in whom diagnosis of pathologic transpyloric DGR is supported by several objective arguments provides most of them with symptomatic and endoscopic improvement parallel to abolishment or normalization of gastric exposure to bile. Postoperative PPI therapy during a 2-month period is to be recommended to prevent the development of an anastomotic ulcer.

Abstract
This study reviews current data regarding duodenogastric and gastroesophageal bile reflux-pathophysiology, clinical presentation, methods of diagnosis (namely, 24-hour intraluminal bile monitoring) and therapeutic management. Duodenogastric reflux (DGR) consists of retrograde passage of alkaline duodenal contents into the stomach; it may occur due to antroduodenal motility disorder (primary DGR) or may arise following surgical alteration of gastoduodenal anatomy or because of biliary pathology (secondary DGR). Pathologic DGR may generate symptoms of epigastric pain, nausea, and bilious vomiting. In patients with concomitant gastroesophageal reflux, the backwash of duodenal content into the lower esophagus can cause mixed (alkaline and acid) reflux esophagitis, and lead, in turn, to esophageal mucosal damage such as Barrett's metaplasia and adenocarcinoma. The treatment of DGR is difficult, non-specific, and relatively ineffective in controlling symptoms. Proton pump inhibitors decrease the upstream effects of DGR on the esophagus by decreasing the volume of secretions; promotility agents diminish gastric exposure to duodenal secretions by improving gastric emptying. In patients with severe reflux resistant to medical therapy, a duodenal diversion operation such as the duodenal switch procedure may be indicated.

Abstract
BACKGROUND The aetiology of inflammation in cardiac mucosa at the gastro-oesophageal junction (carditis) is unclear, although gastro-oesophageal reflux has been suggested. OBJECTIVES To correlate histological features of carditis with oesophageal acid exposure (gastro-oesophageal reflux) and proximal gastric bile exposure (duodenogastric reflux) in patients with symptoms of gastro-oesophageal reflux disease (GORD). METHODS Sixty-six patients with reflux symptoms underwent endoscopy with biopsy, oesophageal manometry, 24-h oesophageal pH testing and 24-h proximal gastric Bilitec 2000 testing. Inflammation in glandular mucosa was assessed using the updated Sydney System. Fifteen healthy volunteers underwent pH and Bilitec 2000 testing and served as controls. RESULTS There was no correlation between either the presence or histological grade of carditis and oesophageal acid exposure or proximal gastric bilirubin exposure. Patients with reflux symptoms had as much duodenogastric reflux into the proximal stomach as did control subjects. CONCLUSIONS We were unable to establish either gastro-oesophageal or duodenogastric reflux as the predominant cause of inflammation in cardiac mucosa.

METHODS: 30 healthy volunteers were divided into two groups: standard diet group (Group 1) 18 cases, free diet group (Group 2) 12 cases. Each subjects were subjected to simultaneous 24 h intragastric pH and spectrophotometric bilirubin concentration monitoring (Bilitec 2000).
RESULTS: There was no difference of preprandial phase bilirubin absorbance between two groups. The absorbance of postprandial phase was significantly increased in group 2 than group 1. There was no difference between preprandial phase and postprandial phase absorbance in group 1. Postprandial phase absorbance was significantly higher in group 2. In a comparison of bile reflux with intragastric pH during night time, there were 4 types of reflux: Simultaneous increase in absorbance and pH in only 19.6%, increase in bilirubin with unchanged pH 33.3%, pH increase with unchanged absorbance 36.3%, and both unchanged in 10.8%. Linear regression analysis showed no correlation between percentage total time of pH < 4 and percentage total time of absorbance > 0.14, r = 0.068, P < 0.05.
CONCLUSION: Because of the dietary effect, high absorbance fluids or foods should be avoided in detection. Intragastric pH and bilirubin monitoring separately predict the presence of duodenal (and/or pancreatic) reflux and bile reflux. They can not substitute for each other. The detection of DGR is improved if the two parameters are combined simultaneously.
