Long-term Outcomes of Laparoscopic Sleeve Gastrectomy as a Revisional Procedure Following Adjustable Gastric Banding: Variations in Outcomes Based on Indication. Obes Surg 2023; 33:3722-3739. [PMID: 37847457 PMCID: PMC10687173 DOI: 10.1007/s11695-023-06886-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 09/27/2023] [Accepted: 10/04/2023] [Indexed: 10/18/2023]
Abstract
BACKGROUND Significant controversy exists regarding the indications and outcomes after laparoscopic adjustable gastric banding (LAGB) conversions to laparoscopic sleeve gastrectomy (LSG). AIM To comprehensively determine the long-term outcomes of sleeve gastrectomy as a revisional procedure after LAGB across a range of measures and determine predictors of outcomes. METHODS Six hundred revision LSG (RLSG) and 1200 controls (primary LSG (PLSG)) were included. Patient demographics, complications, follow-up, and patient-completed questionnaires were collected. RESULTS RLSG vs controls; females 87% vs 78.8%, age 45 ± 19.4 vs 40.6 ± 10.6 years, p = 0.561; baseline weight 119.7 ± 26.2 vs 120.6 ± 26.5 kg p = 0.961). Follow-up was 87% vs 89.3%. Weight loss in RLSG at 5 years, 22.9% vs 29.6% TBWL, p = 0.001, 10 years: 19.5% vs 27% TBWL, p = 0.001. RLSG had more complications (4.8 vs 2.0% RR 2.4, p = 0.001), re-admissions (4.3 vs 2.4% RR 1.8, p = 0.012), staple line leaks (2.5 vs 0.9%, p = 0.003). Eroded bands and baseline weight were independent predictors of complications after RLSG. Long-term re-operation rate was 7.3% for RLSG compared to 3.2% in controls. Severe oesophageal dysmotility predicted poor weight loss. RLSG reported lower quality of life scores (SF-12 physical component scores 75.9 vs 88%, p = 0.001), satisfaction (69 vs 93%, p = 0.001) and more frequent regurgitation (58% vs 42%, p = 0.034). CONCLUSION RLSG provides long-term weight loss, although peri-operative complications are significantly elevated compared to PLSG. Longer-term re-operation rates are elevated compared to PLSG. Four variables predicted worse outcomes: eroded band, multiple prior bands, severe oesophageal dysmotility and elevated baseline weight.

Safety and effectiveness of 1-stage conversion of adjustable gastric band-to-sleeve gastrectomy: a single-institution case-control study. Surg Obes Relat Dis 2021; 18:95-101. [PMID: 34666948 DOI: 10.1016/j.soard.2021.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 08/15/2021] [Accepted: 08/15/2021] [Indexed: 11/20/2022]
Abstract
BACKGROUND Patients are increasingly referred for conversion of laparoscopic adjustable gastric band (LAGB) to laparoscopic Roux-en-Y gastric bypass (LRYGB) or sleeve gastrectomy (SG). The safety of a 1- versus 2-stage approach to this revision is debated. OBJECTIVES We examined the safety and efficacy of 1-stage conversion of LAGB to SG at our institution. SETTING University hospital. METHODS An institutional database was used to retrospectively identify patients who underwent single-stage LAGB-to-SG conversion between 2010 and 2018. Patients were matched 1:1 for age, sex, and body mass index with primary SG patients during this same period. Primary endpoints were operative time, complication rate, length of hospital say, and weight loss 12 months from surgery. RESULTS Two-hundred and twenty-nine patients undergoing conversion of LAGB to SG were identified. Median postoperative length of hospital stay was 2 days. Two patients (.8%) developed surgical site infection. One patient (.4%) developed a postoperative myocardial infarction. There were 4 total readmissions (1.7%) and 1 reoperation within 30 days (.4%). There were no statistically significant differences in 30-day complication rates between groups. Weight loss at 12 months was significantly different: Median body mass index loss for conversion patients was 5.1 kg/m2 compared with 8.85 kg/m2 for patients in the primary SG group (P < .0001). CONCLUSION Single-stage conversion of LAGB to SG is safe and effective. Patients may not experience the same extent of weight loss as those with primary SG. Our findings represent the largest single-institutional experience to date and support a 1-stage approach whenever feasible.

Abstract
Pseudoachalasia accounts for up to 4% of patients who present with achalasia-like picture and most often relates to occult malignancy at the cardia or gastroesophageal junction. Thus, any delay in diagnosis might lead to more advanced disease and less chance for curative therapy, not to mention the risk of serious complications resulting from the treatment of supposed achalasia instead of the true underlying cause. The entity should be suspected in patients with advanced age of onset, a shorter duration of symptoms, profound weight loss and difficulty in passing the gastroesophageal junction on endoscopy. The diagnosis of pseudoachalasia can be challenging as upper endoscopy with biopsy might be false negative in 25% of cases and lesions cannot always be detected on computerized tomography scan. Endoscopic ultrasound and guided biopsy play an increasingly important role in the workup of this condition. Treatment of pseudoachalasia depends on the underlying cause. The aim of this review is to highlight the clinicopathological features that distinguish pseudoachalasia from achalasia and the most appropriate diagnostic workup as well as the subsequent management for this condition.

Abstract
PURPOSE OF REVIEW Bariatric surgery and endoluminal bariatric therapies (EBTs) form an increasingly utilized therapeutic approach to treat obese patients but may worsen gastroesophageal reflux disease (GERD). In this updated article, we review the evidence on the effects of bariatric procedures on GERD. FINDINGS Recent evidence implicates sleeve gastrectomy with the highest rates of de novo GERD and Barrett's esophagus (BE), whereas malabsorptive-restrictive procedures such as Roux-en-Y gastric bypass (RYGB) and one anastomosis gastric bypass (OAGB) were shown to have significantly lower reported rates. The intragastric balloon (IGB) has been associated with increased likelihood of GERD, whereas insufficient evidence exists linking endoscopic sleeve gastroplasty (ESG) to GERD. SUMMARY Gastroesophageal reflux disease may be treated with some bariatric procedures but is often developed de novo as a result of the change in anatomy. Patients set to undergo bariatric surgery may benefit from pre-procedural endoscopy to choose the more suitable therapy. Further studies with objective measurements of GERD post procedure may provide more insight into the effects of bariatric therapies on reflux, especially more novel ones such as ESG.

Abstract
Gastroesophageal reflux disease (GERD) and obesity coexist in many patients in the Western population. The association is not coincidental, since GERD pathophysiology is, in part, linked to obesity. Visceral adipose tissue secretes hormones, which increase the risk of GERD. Obesity increases esophageal motor disorders and higher number of transient lower esophageal sphincter relaxations. Central obesity increases abdominal-thoracic pressure gradient and disrupts the gastroesophageal junction by inducing hiatal hernia formation. Obese patients benefit from weight loss by diet to decrease GERD symptoms; however, Roux-en-Y gastric bypass surgery is associated with a higher weight loss and a decrease in GERD symptoms, and is considered the best way to treat both diseases at the same time.

Abstract
INTRODUCTION The effect of the laparoscopic adjustable gastric band (LAGB) on esophageal acid exposure and reflux is poorly understood. Optimal technique and normative values for acid exposure have not been established in this group. METHODS High-resolution manometry (HRM) and 24-h ambulatory esophageal pH monitoring were performed in three groups: asymptomatic LAGB, symptomatic LAGB, and pre-operative reflux patients. This technique utilized intraluminal pressure signatures during HRM to guide accurate pH sensor placement. RESULTS The LAGB groups were well matched: age 48 vs 51 years (p = 0.249), weight loss 27.3 vs 26.7 kg (p = 0.911). The symptomatic group had a larger gastric pouch (5.2 vs 3.3 cm, p = 0.012), with higher esophageal acid exposure (10.8 vs 0.9%, p < 0.001). Two acidification patterns were observed: irritant and volume acidification, associated with substantial supine acidification. Symptomatic LAGB had altered esophageal motility, with poorer lower esophageal sphincter basal tone (8.0 vs 17.7 mmHg, p = 0.022) and impaired contractility of the lower esophageal segment (90 vs 40%, p = 0.009). Compared to pre-operative reflux patients, symptomatic LAGB patients demonstrated higher total and supine esophageal acid exposure (10.8 vs 7.0%, p = 0.010; 14.9 vs 5.1%, p < 0.001), less symptoms (2 vs 6, p = 0.001) and lower symptom index (0.7 vs 0.9, p = 0.010). CONCLUSIONS Ambulatory pH monitoring is an effective technique if the pH sensor is positioned appropriately using HRM. The correctly positioned LAGB appears associated with low esophageal acidification. In contrast, patients with symptoms or pouch dilatation can have markedly elevated esophageal acidification, particularly when supine. This is a different pattern compared to pre-operative patients and importantly can be disproportionate to symptoms.

Abstract
INTRODUCTION AND PURPOSE Sleeve gastrectomy (SG) is gaining ground in the field of bariatric surgery. Data are scarce on its impact on esophagogastric physiology. Our aim was to evaluate the impact of SG on esophagogastric motility with high-resolution impedance manometry (HRIM) and to assess the usefulness of HRIM in patients with upper gastrointestinal (GI) symptoms after SG. METHODS A retrospective analysis of 53 cases of HRIM performed after SG was conducted. Upper GI symptoms at the time of HRIM were scored. HRIM was analyzed according to the Chicago classification v3.0. A special attention was devoted to the occurrence of increased intragastric pressure (IIGP) after water swallows and reflux episodes as detected with impedance. A measurement of sleeve volume and diameter was performed with CT scan in a subgroup of patients. RESULTS IIGP occurred very frequently in patients after SG (77 %) and was not associated with any upper GI symptoms, specific esophageal manometric profile, or impedance reflux. Impedance reflux episodes were also frequently observed after SG (52 %): they were significantly associated with gastroesophageal reflux (GER) symptoms and ineffective esophageal motility. The sleeve volume and diameters were also significantly smaller in patients with impedance reflux episodes (p < 0.01). CONCLUSION SG significantly modified esophagogastric motility. IIGP is frequent, not correlated to symptoms, and should be regarded as a HRIM marker of SG. Impedance reflux episodes were also frequent, associated with GER symptoms and esophageal dysmotility. HRIM may thus have a clinical impact on the management of patients with upper GI symptoms after SG.

Abstract
BACKGROUND Proximal luminal dilatation (PLD) is one of the most significant challenges following laparoscopic adjustable gastric banding (LAGB). If PLD is identified at an early stage, there is potential to avoid reoperation or irreversible change by implementing nonsurgical measures. The success of these strategies is unknown. The aim of this study was to determine the outcome of how often PLD can be successfully treated nonsurgically. METHODS The records of patients who underwent primary LAGB insertion by a single surgeon from January 2005 to December 2006 were reviewed. Study participants were all patients who had subsequently undergone a postoperative liquid contrast swallow demonstrating a PLD. The severity of PLD, subsequent management, and outcomes were recorded and assessed. RESULTS There were 354 patients who underwent a primary LAGB insertion during the study period. Seventy-eight patients were found to have varying degrees of PLD and had an attempt at nonsurgical management. Thirty-four of these patients (43.6 %) were successfully managed nonsurgically at a mean follow-up of 2.8 years (33.2 months, CL ± 3.2). The success with nonsurgical management was lower if the symmetrical pouch dilatation was more severe or gastric prolapse was seen at presentation, and if no improvement in liquid contrast swallow was seen. CONCLUSIONS PLD can often be successfully managed with nonsurgical measures, maintaining good weight loss in the intermediate term. Patients with more significant dilatation are more likely to require revisional surgery. Early recognition may have a role in preventing surgery or more severe abnormalities.

Abstract
BACKGROUND Gastric banding surgery can fail if the patient develops frequent vomiting, intolerance of common food types or reflux. These patients can be divided into those with a well-defined anatomical problem such as slippage and those without. Intermittent gastric prolapse (IGP) is a possible explanation for some patients who do not achieve adequate early satiety without excessive food intolerance but have normal imaging. METHODS A series of eight patients was identified over a 2-year period with findings consistent with IGP. Cases were identified in the process of normal clinical practice and details reviewed retrospectively. Specific diagnostic methods included measures to increase pouch pressure above the band by either stress barium or endoscopy with pressure challenge. RESULTS The median time until diagnosis of IGP was 48.0 months (16-124), and weight loss over that time was 26.4 kg, or 69.6 % excess weight loss (EWL) (5.8-101.8). This fell to 43.7 % EWL after IGP was diagnosed and managed. The mean fill volume when the patients experienced IGP was 6.8 ml (4.5-9.0). Most patients were diagnosed by radiological investigation. Four patients underwent revisional surgery with the remainder treated conservatively. CONCLUSIONS Intermittent gastric prolapse may explain excessive food and fluid intolerance in gastric band patients who have normal initial imaging. These patients typically experience gross food intolerance with a relatively small increment in fluid volume with relief when the increment is removed. The diagnosis is best made with either modified stress barium or endoscopy with pressure challenge. Management entails establishment of a safe fill volume, modification of weight loss expectations and earlier discussion of revisional surgery.

Abstract
This review focus on the utility of HRM for the evaluation of gastric motility. The evaluation of gastric motility has clinical implications for the study of a myriad of diseases. Disordered motility represents a spectrum of dysfunction ranging from delayed gastric emptying to abnormally rapid gastric transit. Gastric motility may be measured by a variety of methods with different efficacy and different variables that may be obtained. High-resolution manometry was created and added to the diagnostic armamentarium. The methods and outcomes for the study of proximal motility that may be useful to assess the thoracoabdominal pressure gradient, gastric filling and accommodation are described. Also, studies on antroduodenal manometry are reviewed. High-resolution manometry allows gastric manometry without technical limitations found on conventional manometry; however, studies are still on the phase of understanding the normal findings.

Abstract
The link between obesity and GERD is clear on all measures of the disease: clinical symptoms, erosive oesophagitis, acid esophageal exposure, and complications. The pathogenesis of this link may be due to general factors such as visceral adiposity, oestrogen levels, or decrease of Helicobacter pylori infection with increased gastric acid secretion. Increased abdominal pressure leads to disruption of the esophago-gastric junction and hiatal hernia, and esophageal motility may be modified by obesity. Weight loss does improve GERD, but lifestyle modifications and diet are usually insufficient in the long-term for morbid obesity. GERD and hiatal hernia are key issues in bariatric surgery, and are widely discussed because of important implications. It is not currently certain which procedure should be favoured in case of GERD; yet gastric bypass offers the best guarantee of success. Hiatal hernia repair is also deemed necessary by some authors at the same time of the bariatric surgery. Minimally invasive techniques pose a new challenge to this issue, both technically and theoretically.

Abstract
RACIONAL:A cirurgia bariátrica pode provocar alterações na motilidade esofágica. Entretanto, existe paucidade de estudos com a manometria de alta resolução. OBJETIVO: Avaliar a motilidade esofágica em pacientes submetidos à derivação gástrica em Y-de-Roux para obesidade mórbida. MÉTODOS: Foram estudados 18 pacientes assintomáticos submetidos à derivação gástrica em Y-de-Roux por laparotomia. Todos foram submetidos à manometria de alta resolução em média três anos após a operação. RESULTADOS: O esfíncter esofagiano inferior teve pressão basal média de 18±13 (variação 0-51) mmHg; sete pacientes (39%) apresentaram hipotonia e um (5%) hipertonia. O relaxamento foi anormal em um paciente. O comprimento total e abdominal do esfíncter foi de 4±1 (1-7) cm e 2±1 (0-3) cm, respectivamente. A amplitude distal do corpo esofágico (média de 3 e 7 cm acima do esfíncter) foi de 77±22 (40-120) mmHg e um paciente (5%) teve hipocontratilidade. Ondas peristálticas foram vistas em 95±0% (60-100).

Abstract
BACKGROUND The most common bariatric procedure in Australia is laparoscopic adjustable gastric banding (LAGB). Although successful, there is a substantial long-term complication and failure rate. Band removal and conversion to Roux-en-Y gastric bypass (RYGB) can be an effective treatment for complicated or failed bands. There is increasing evidence supporting good weight loss and resolution of band-related complications after conversion. METHODS A prospective database of all bariatric procedures is maintained. Patients having revision of LAGB to RYGB between December 2007 and April 2011 were included in this study. Indications for surgery, operative details, morbidity and mortality, weight loss data, and post-operative symptoms were recorded. RESULTS Eighty-two patients were included. Indications for surgery were inadequate weight loss (n = 42), adverse symptoms (reflux = 8, dysphagia = 2), and band complications (band erosion = 7, band sepsis = 1, band slip = 11, esophageal dilatation = 11). Seventy-eight percent of procedures were completed in a single stage and 96.3% laparoscopically. There was no 30-day mortality. Total morbidity was 46.3% (minor complications = 32.9%, major complications = 13.4%). Median BMI was 43 kg/m(2) pre-RYGB and 34 kg/m(2) after 12 months. All patients with adverse band-related symptoms had resolution. CONCLUSIONS LAGB has a considerable complication and failure rate. Conversion of these patients to RYGB results in further weight loss and resolution of adverse symptoms. This is a challenging procedure, but can usually be performed in a single stage with acceptable morbidity and mortality. These patients should be treated in high-volume, subspecialty bariatric units.

Abstract
Laparoscopic adjustable gastric banding (LAGB) has rapidly emerged as a popular bariatric procedure because of its safety, efficacy, durability and adjustability. Despite widespread use, there is limited understanding of how it induces weight loss. Previously, it has been classified as a restrictive procedure, physically limiting the patient to a small meal that subsequently slowly empties into the distal stomach. However, the tiny pouch of stomach created above the LAGB appears to be unable to accommodate even the smallest of meals. Therefore, the key mechanism has been hypothesized to be the induction of satiety via, as yet, undefined pathways. The critical question remains: what are the key physiological changes that lead to satiety and weight loss? In successful LAGB patients, a consistent intraluminal pressure at the level of the LAGB of 26.9 ± 19.8 mm Hg is observed. Studies using semi-solid swallows combined with intraluminal pressure recordings have demonstrated that semi-solid transit across the resistance of the LAGB is mediated by repeated esophageal peristaltic contractions (mean 4.5 ± 2.9) that produce episodic flow, interspersed by reflux events. Failed transit results in obstruction and regurgitation, whereas dilatation of the supraband stomach induces severe and intolerable reflux. Overall gastric emptying does not appear to be significantly altered following LAGB. Focused investigations have shown that the supraband stomach is empty of an ingested meal 1-2 min after intake ceases. Considerable progress has been made in understanding the mechanical physiological effects of the LAGB on esophageal and proximal gastric function. These have been correlated with patient outcomes and sensations. On the basis of recent data, it appears that the LAGB activates the peripheral satiety mechanism without physically restricting the meal size. Therefore, it should not be classified as a restrictive procedure. The precise mechanism of weight loss with the LAGB remains to be delineated.

Abstract
Esophageal and gastric pouch dilatations are not uncommon after laparoscopic adjustable gastric banding for morbid obesity. Most of the cases are treated by gastric band deflation or removal. We report here the case of a 44-year-old woman with vomiting and severe dysphagia persisting despite gastric band removal, in relation with a scar stenosis and a gastric pouch trapped in the thorax, treated by laparoscopic surgery. This case underlines the usefulness of high-resolution manometry in the diagnostic work-up of these often difficult cases.

Abstract
BACKGROUND Laparoscopic adjustable gastric banding (LAGB) induces and sustains weight loss, likely by activating the peripheral satiety mechanism. Recent data suggests that food is not retained above the optimally adjusted LAGB, suggesting that an alternate mechanism is inducing satiety. How transit and gastric emptying change following LAGB and correlate with satiety and weight loss have not been adequately defined. METHODS LAGB patients underwent preoperative and 12-month follow-up nuclear scintigraphic assessments of esophageal transit and gastric emptying. A new technique that allowed the calculation of emptying times and transit through the supra- and infraband compartments was used to assess emptying and transit patterns postoperatively. RESULTS Postoperatively, patients reported increased satiety both after a standard fast (3.7 ± 2.3 vs. 4.8 ± 2.1, p = 0.04) and following a standard semisolid meal (5.9 vs. 7.8 ± 1.7, p = 0.003). The mean percent excess weight loss was 48.5 ± 23.2%. The gastric emptying half-time (minutes) did not change significantly (63.5 ± 41.1 vs. 73.3 ± 26.8, p = 0.64). Semisolid transit into the infraband stomach was delayed briefly postoperatively in more patients (11 vs. 2, p = 0.001). There was minimal retention of the meal above the LAGB 2 min after commencing the gastric emptying study (median, 3%; interquartile range, 1.75-10); therefore, an emptying half-time of the supraband region could not be defined. CONCLUSIONS Weight loss, satiety, and early satiation following LAGB were associated with briefly delayed bolus transit into the infraband stomach. Retention of the semisolid meal above the LAGB was not observed. This is further evidence that suggests satiety develops following LAGB without physical restriction of meal size.

Abstract
BACKGROUND Dysphagia and vomiting are frequent after laparoscopic gastric banding (LAGB). These symptoms could be secondary to esophageal motility disorders. Our aim was to assess esophageal motility and clearance in symptomatic LAGB patients using high resolution manometry (HRM). METHODS Twenty-two LAGB patients with esophageal symptoms (dysphagia, vomiting, and regurgitations) were included. Esophageal motility was studied using HRM (ManoScan®, Sierra Systems) and classified according to the Chicago classification. RESULTS The median delay between surgery and manometry evaluation was 6.3 years (range 1-10). Manometric data were considered as normal in only 2 patients. Achalasia was diagnosed in 3 cases, functional EGJ obstruction in 15, hypotensive peristalsis in 2. During swallowing pan-esophageal pressurization was observed in 6 patients, hiatal hernia pressurization in 7 and gastric pouch pressurization in 2. The intra-bolus pressure was elevated in 18 patients. LAGB was deflated in 6 patients and removed in 12. In 2 patients with unchanged symptoms after LAGB removal motility disorders persisted (1 achalasia, 1 functional EGJ obstruction). CONCLUSION In symptomatic LAGB patients, esophageal dysmotility is frequent. High resolution manometry allows the assessment of esophageal clearance and provides guidance for the choice of treatment.

Abstract
BACKGROUND The components of esophageal function important to success with laparoscopic adjustable gastric banding (LAGB) are not well understood. A pattern of delayed, however, successful bolus transit across the LAGB is observed. METHODS Successful LAGB patients underwent a high-resolution video manometry study in which bolus clearance, flow, and intraluminal pressures were recorded. Liquid and semi-solid swallows and stress barium (a combination of semi-solid swallows and liquid barium) were performed. A new measurement, the lower esophageal contractile segment (LECS), was defined and evaluated. RESULTS Twenty patients participated (mean age 48.3 +/- 12.0 years, four men, %excess weight loss 65.6 +/- 18.0). During semi-solid swallows, two patterns of esophageal clearance were observed: firstly, a native pattern (n = 10) similar to that which is expected in non-LAGB patients; secondly, a lower esophageal sphincter-dependent pattern (n = 7), where flow only occurred when the intrabolus pressure increased during the lower esophageal sphincter (LES) aftercontraction. In both patterns, if there was incomplete bolus clearance, reflux was observed and was usually followed by another swallow. A mean of 4.5 +/- 2.9 contractions were required to clear the semi-solid bolus. Contractions with an intact LECS demonstrated longer flow duration: 7.1 +/- 3.8 vs.1.6 +/- 3.2 s, p < 0.005. During the stress barium, an intrabolus pressure of 44.5 +/- 16.0 mm Hg leads to cessation of intake. CONCLUSIONS In LAGB patients, normal esophageal peristaltic contractions transition to a LES aftercontraction, producing trans-LAGB flow. Repeated contractions are required to clear a semi-solid bolus. Incorporating measurements of the LECS into assessments of esophageal motility in LAGB patients may improve the usefulness of this investigation.

Criteria for assessing esophageal motility in laparoscopic adjustable gastric band patients: the importance of the lower esophageal contractile segment. Obes Surg 2009; 20:316-25.

Abstract
BACKGROUND Esophageal function appears critical in laparoscopic adjustable gastric band (LAGB) patients; however, conventional motility assessments have not proven to be clinically useful. Recent combined video fluoroscopic and high-resolution manometric studies have identified important components of esophageal function in LAGB patients. METHODS Successful and symptomatic LAGB patients, with normal or mildly impaired esophageal peristalsis, underwent a standardized, water swallow, high-resolution manometry protocol designed specifically to assess the lower esophageal contractile segment (LECS), in combination with conventional measures of esophageal motility. Differences in response to changes in LAGB volume were assessed. RESULTS There were 101 symptomatic and 29 successful patients. More symptomatic patients had a mild impairment in esophageal motility (39.6% vs. 3.4%, p < 0.005). Successful patients demonstrated an intact LECS during normal swallows more frequently than symptomatic patients (95% vs. 43%, p < 0.005). Absolute intraluminal pressures were not different between the groups. Removing all fluid from the LAGB revealed more hypotensive swallows in the symptomatic patients (30% vs. 17%, p = 0.002), an effect not observed when the LAGB volume was increased (8% vs. 5%, p = 0.21). Receiver operator characteristic analysis determined that an intact LECS in 70% of normal swallows defined normal motility in LAGB patients. CONCLUSIONS The LECS is a valuable measure of esophageal function in LAGB patients and complements conventional manometric criteria. Symptomatic patients have less normal swallows; however, these also frequently demonstrate a deficient LECS. Further information can be elucidated by performing swallows at differing LAGB volumes. High-resolution manometry, using these adapted criteria, is now a useful in the investigation in symptomatic LAGB patients.
