A total fundoplication is not an obstacle to esophageal emptying after heller myotomy for achalasia: results of a long-term follow up

Objective:The aim of this study was to evaluate the role and efficacy of a total 360° wrap, Nissen-Rossetti fundoplication, after esophagogastromyotomy in the treatment of esophageal achalasia. Summary Background Data:Surgery actually achieves the best results in the treatment of esophageal achalasia; the options vary from a short extramucosal esophagomyotomy to an extended esophagogastromyotomy with an associated partial fundoplication to restore the main antireflux barrier. A total 360° fundoplication is generally regarded as an obstacle to esophageal emptying. Matherials and Methods:Since 1992 to November 2003, a total of 195 patients (91 males, 104 females), mean age 45.2 years (range, 12–79 years), underwent laparoscopic treatment of esophageal achalasia. Intervention consisted of Heller myotomy and Nissen-Rossetti fundoplication with intraoperative endoscopy and manometry. Results:In 3 patients (1.5%), a conversion to laparotomy was necessary. Mean operative time was 75 ± 15 minutes. No mortality was observed. Overall major morbidity rate was 2.1%. Mean postoperative hospital stay was 3.6 ± 1.1 days (range, 1–12 days). At a mean clinical follow up of 83.2 ± 7 months (range, 3–141 months) on 182 patients (93.3%), an excellent or good outcome was observed in 167 patients (91.8%) (dysphagia DeMeester score 0–1). No improvement of dysphagia was observed in 4 patients (2.2%). Gastroesophageal pathologic reflux was absent in all the patients. Conclusions:Laparoscopic Nissen-Rossetti fundoplication after Heller myotomy is a safe and effective treatment of esophageal achalasia with excellent results in terms of dysphagia resolution, providing total protection from the onset of gastroesophageal reflux.

Early systemic sclerosis: assessment of clinical and pre-clinical organ involvement in patients with different disease features

OBJECTIVE To assess internal organ involvement in early SSc at presentation. METHODS One hundred and fifteen patients admitted to a tertiary centre because of RP, who did not present any routinely detectable scleroderma-related internal organ involvement, were investigated for ANA and videocapillaroscopy, and underwent history and physical examination to detect symptoms/signs suggestive of SSc. Patients were then subdivided into three groups: (i) early SSc, constituted by patients without clinical manifestations other than RP, but with scleroderma marker autoantibodies and/or typical capillaroscopic abnormalities; (ii) probable SSc, constituted by patients with the same autoantibody and/or capillaroscopic status as early SSc patients, but with any of the following manifestations: digital ulcers/scars, puffy fingers, arthritis, telangiectasia, dysphagia/heartburn, shortness of breath; (iii) UCTD, constituted by patients with a specific (i.e. disease antibody marker) ANA and capillaroscopic findings plus any disease manifestation. All patients were investigated by lung functional study and B-mode echo-Doppler-cardiography. Patients who consented underwent oesophageal manometry. RESULTS An inverted mitral E : A ratio (i.e. early scleroderma cardiac involvement) and/or a diffusing lung capacity for CO <80% of the predictive value (i.e. early lung involvement) and/or basal low oesophageal sphincter pressure <15 mmHg (i.e. early oesophageal involvement) were detected in 37/51 probable SSc patients (72%), 8/19 early SSc patients (42%) and 12/45 UCTD patients (27%). CONCLUSION A scleroderma-related internal organ involvement was detected in patients from each group and, more importantly, was pre-clinical in a number of cases.

Association between persistent symptoms and long-term quality of life after laparoscopic total fundoplication

BACKGROUND We investigated which factors are significantly associated with long-term quality of life after laparoscopic total fundoplication in the treatment of gastroesophageal reflux disease. METHODS Patients (n = 144) were given a standardized frequency-intensity symptoms questionnaire and the Short-Form 36 Health Survey for quality-of-life evaluation before and after laparoscopic total fundoplication. RESULTS At follow-up evaluation (n = 102), patients had a significant reduction in their symptoms score and no deterioration in quality of life. A significant association with postoperative dysphagia for solids and/or liquids was found in the physical component summary score of the Short-Form 36 administered to patients postoperatively (P = .003). CONCLUSIONS In this study, laparoscopic total fundoplication was a safe and effective surgical treatment for gastroesophageal reflux disease, generally offering an improved long-term quality of life, with the exception of a minority of patients (6 of 102 patients; 5.8%) who experienced persistent severe dysphagia.

Laparoscopic Nissen-Rossetti fundoplication with routine use of intraoperative endoscopy and manometry: technical aspects of a standardized technique.

BackgroundSeveral different ways of fashioning a total fundoplication lead to different outcomes. This article addresses the technical details of the antireflux technique we adopted without modifications for all patients with GERD beginning in 1972. In particular it aims to discuss the relation between the mechanism of function of the wrap and the physiology of the esophagus.MethodsThe study population consisted of 380 patients affected by GERD with a 1-year minimum of follow-up who underwent laparoscopic Nissen-Rossetti fundoplication by a single surgeon.ResultsNo conversion to open surgery and no mortality occurred. Major complications occurred in 4 patients (1.1%). Follow-up (median 83 months; range: 1–13 years) was achieved in 96% of the patients. Ninety-two percent of the patients were satisfied with the results of the procedure and would undergo the same operation again. Postoperative dysphagia occurred in 3.5% of the patients, and recurrent heartburn was observed in 3.8%.ConclusionsLaparoscopic Nissen-Rossetti fundoplication with the routine use of intraoperative manometry and endoscopy achieved good outcomes and long-term patient satisfaction with few complications and side-effects. Appropriate preoperative investigation and a correct surgical technique are important in securing these results.

Hiatal Hernia Recurrence: Surgical Complication or Disease? Electron Microscope Findings of the Diaphragmatic Pillars

IntroductionAlthough laparoscopic Nissen fundoplication has been recognized as the standard of care for hiatal hernia (HH) repair, HH recurrence due to breakdown of the hiatoplasty have been reported as a common mechanism of failure after primary repair. Different surgical techniques for diaphragmatic pillars closure have been proposed, but the problem remains unsolved. The authors hypothesized that ultrastructural illness may be implicated in this recurrence. The aim of this study was to investigate the presence of changes at esophageal hiatal area in patients with and without HH.Materials and MethodsOne hundred and thirty-two laparoscopic samples from phrenoesophageal membrane and diaphragmatic crura were collected from 33 patients with gastroesophageal reflux disease and HH (HH group) and 60 samples from 15 patients without HH enrolled as the control group (NHH group). All specimens were processed and analyzed by transmission electron microscopy.ResultsMuscular and connective samples from the NHH group showed no ultrastructural alterations; similar results were found in phrenoesophageal ligament samples from the HH group. In contrast, 94% of the muscular samples obtained from the crura of the HH group have documented four main types of alterations. In 75% of HH patients, the pillar lesions were severe.ConclusionPatients with hiatal hernia have ultrastructural abnormalities at the muscular tissue of the crura that are not present in patients with a normal gastroesophageal junction. There is no difference in the microscopic damage at the connective tissue of the phrenoesophageal membrane surrounding the esophagus of the two groups of patients. The outcome of antireflux surgery could depend not only on the adopted surgical technique but also on the underlying status of the diaphragmatic crura.

Early systemic sclerosis: short-term disease evolution and factors predicting the development of new manifestations of organ involvement

IntroductionWe investigated early systemic sclerosis (SSc) (that is, Raynauds phenomenon with SSc marker autoantibodies and/or typical capillaroscopic findings and no manifestations other than puffy fingers or arthritis) versus undifferentiated connective tissue disease (UCTD) to identify predictors of short-term disease evolution.MethodsThirty-nine early SSc and 37 UCTD patients were investigated. At baseline, all patients underwent clinical evaluation, B-mode echocardiography, lung function tests and esophageal manometry to detect preclinical alterations of internal organs, and were re-assessed every year. Twenty-one early SSc and 24 UCTD patients, and 25 controls were also investigated for serum endothelial, T-cell and fibroblast activation markers.ResultsAt baseline, 48.7% of early SSc and 37.8% of UCTD patients had at least one preclinical functional alteration (P > 0.05). Ninety-two percent of early SSc patients developed manifestations consistent with definite SSc (that is, skin sclerosis, digital ulcers/scars, two or more teleangectasias, clinically visible nailfold capillaries, cutaneous calcinosis, X-ray bibasilar lung fibrosis, X-ray esophageal dysmotility, ECG signs of myocardial fibrosis and laboratory signs of renal crisis) within five years versus 17.1% of UCTD patients (X2 = 12.26; P = 0.0005). Avascular areas (HR = 4.39 95% CI 1.18 to 16.3; P = 0.02), increased levels of soluble IL-2 receptor alpha (HR = 4.39; 95% CI 1.03 to 18.6; P = 0.03), and of procollagen III aminopropeptide predicted disease evolution (HR = 4.55; 95% CI 1.18 to 17; P = 0.04).ConclusionMost early SSc but only a few UCTD patients progress to definite SSc within a short-term follow-up. Measurement of circulating markers of T-cell and fibroblast activation might serve to identify early SSc patients who are more likely to develop features of definite SSc.

Is Nasogastric Decompression Useful in Prevention of Leaks After Laparoscopic Sleeve Gastrectomy? A Randomized Trial

ABSTRACT Introduction: Although its excellent results, laparoscopic sleeve gastrectomy (LSG) presents major complications ranging from 0% to 29%. Among them, the staple line leak presents an incidence varying from 0% to 7%. Many trials debated about different solutions in order to reduce leaks’ incidence. No author has investigated the role of gastric decompression in the prevention of this complication. Aim of our work is to evaluate if this procedure can play a role in avoiding the occurrence of staple line leaks after LSG. Materials and Methods: Between January 2008 and November 2012, 145 patients were prospectively and randomly included in the study. Seventy patients composed the group A, whose operations were completed with placement of nasogastric tube; the other 75 patients were included in the group B, in which no nasogastric tube was placed. Results: No statistical differences were observed between group A and group B regarding gender distribution, age, weight, and BMI. No intraoperative complications and no conversion occurred in both groups. Intraoperative blood loss (50.1 ± 42.3 vs. 52.5 ± 37.6 ml, respectively) and operative time (65.4 ± 25.5 vs. 62.6 ± 27.8 min, respectively) were comparable between the two groups (p: NS). One staple line leak (1.4%) occurred on 6th postoperative day in group A patients. No leak was observed in group B patients. Postoperative hospital stay was significantly longer in group A vs. group B patients (7.6 ± 3.4 vs. 6.2 ± 3.1 days, respectively, p: 0.04). Conclusions: Routine placement of nasogastric tube in patients operated of LSG seems not useful in reducing leaks’ incidence.

Gastroesophageal reflux disease and obesity: do we need to perform reflux testing in all candidates to bariatric surgery?

INTRODUCTION Obesity is a strong independent risk factor of gastroesophageal reflux disease (GERD) symptoms and esophageal erosions. However the relationship between obesity and GERD is still a subject of debate. In fact, if in most cases bariatric surgery can diminish reflux by losing a large amount of fat, on the other hand some restrictive procedure can worsen or cause the presence of GERD. Thus, it is unclear if patients candidate to bariatric surgery have to perform pre-operative reflux testing or not. AIM of the study was to verify the presence of GERD patterns in patients candidate to surgery and the need of pre-operative reflux testing. METHODS All patients underwent to a standardized questionnaire for symptoms severity (GERQ), upper endoscopy, high resolution manometry (HRiM) and impedance pH-monitoring (MII-pH). Patients were stratified into: group 1 (negative for both GERQ and endoscopy), group 2 (positive for GERQ and negative for endoscopy), group 3 (positive for both GERQ and endoscopy). A healthy-volunteers group (HV) was assessed. RESULTS One hundred thirty-nine subjects (obese, 124; HV normal weight, 15) were studied. Group 1 showed comparable mean LES pressure, peristaltic function, bolus transport and presence of hiatal hernia than HV. Group 2 showed a reduction of these parameters, while group 3 showed a statistical significant reduction in LES pressure, peristaltic function, bolus transport and increase in presence of hiatal hernia. At MII-pH, Group 1 showed a not significant increase in reflux patterns; group 2 and 3 showed a significant increase in esophageal acid exposure and in number of refluxes (both acid and weakly acid), with group 3 showing the higher grade of reflux pattern. CONCLUSIONS Obese subjects with pre-operative presence of GERD symptoms and endoscopical signs could be tested with HRM and MII-pH before undergoing bariatric surgery, especially for restrictive procedures. On the other hand, obese patients without any sign of GERD could not be tested for reflux, showing similar patterns to HV.

Sleeve gastrectomy improves obstructive sleep apnea syndrome (OSAS): 5 year longitudinal study

BACKGROUND Obstructive sleep apnea syndrome (OSAS) is prevalent among morbidly obese patients. Evaluation of the specific effects of sleeve gastrectomy (SG) on upper airway function has not been reported. Given the possibility that some patients will not respond despite weight loss, no studies have investigated whether other mechanisms may be responsible for persistent OSAS after bariatric surgery. OBJECTIVES To evaluate by subjective and objective assessment the impact of SG on upper respiratory physiology in the long-term. SETTING University Hospital, Division of Bariatric and ENT Surgery, in Italy. METHODS Thirty-six consecutive patients with OSAS who underwent laparoscopic SG were prospectively enrolled. The effect of SG on respiratory function and OSAS was followed for 5 years. RESULTS All patients completed the 5-year follow-up. A significant (P<.001) improvement in modified Epworth Sleepiness Scale questionnaire (ESS) was obtained in 91.6% (33/36) of patients. The Apnea/Hypopnea index (AHI) improved in 80.6% (29/36) of patients after surgery (from 32.8 ± 1.7 to 5.8 ± 1.2 (P<.001), 4.9 ± 1.7). The remaining 19.4% (7/36) of patients with a positive ESS and/or AHI all had an associated respiratory resistance due to nasal obstructive diseases. CONCLUSION SG improved OSAS overall, but patients who did not improve or only partially improved despite weight loss were found to have an associated nasal responsible pathology. How these patients will respond to nasal surgery and whether a 2-step procedure should be recommended for OSAS patients requires further study.

Costs of laparoscopic and open liver and pancreatic resection: A systematic review

AIM To study costs of laparoscopic and open liver and pancreatic resections, all the compiled data from available observational studies were systematically reviewed. METHODS A systematic review of the literature was performed using the Medline, Embase, PubMed, and Cochrane databases to identify all studies published up to 2013 that compared laparoscopic and open liver [laparoscopic hepatic resection (LLR) vs open liver resection (OLR)] and pancreatic [laparoscopic pancreatic resection (LPR) vs open pancreatic resection] resection. The last search was conducted on October 30, 2013. RESULTS Four studies reported that LLR was associated with lower ward stay cost than OLR (2972 USD vs 5291 USD). The costs related to equipment (3345 USD vs 2207 USD) and theatre (14538 vs 11406) were reported higher for LLR. The total cost was lower in patients managed by LLR (19269 USD) compared to OLR (23419 USD). Four studies reported that LPR was associated with lower ward stay cost than OLR (6755 vs 9826 USD). The costs related to equipment (2496 USD vs 1630 USD) and theatre (5563 vs 4444) were reported higher for LPR. The total cost was lower in the LPR (8825 USD) compared to OLR (13380 USD). CONCLUSION This systematic review support the economic advantage of laparoscopic over open approach to liver and pancreatic resection.
