Abstract
BACKGROUND Prosthetic vascular grafts placed surgically or via endovascular techniques can be subject to the risk of life-threatening graft infections. The Omniflow II vascular prosthesis is a biosynthetic graft that was reported to have favorable properties in resisting infections. MATERIALS AND METHODS We retrospectively reviewed our 3 years' experience of using the Omniflow II prostheses for aortoiliac reconstructions in patients considered to carry a substantial risk of subsequent prosthetic graft infections (prevention group) as well as in patients with actively infected prosthetic vascular grafts (treatment group). RESULTS Aorto-bi-iliac (n = 4) and aortobifemoral (n = 12) vascular reconstructions were performed using bifurcated Omniflow II prostheses in nine patients in the prevention group and seven patients in the treatment group. During mean follow-up of 28.6 ± 17.2 months, there was one case of graft infection (6.3%) and graft thrombosis (6.3%) with subsequent successful thrombectomy. Early and late surgical revisions were required in eight (50%) and two (12.6%) patients, respectively. All graft prostheses were patent at last follow-up. CONCLUSION Using bifurcated Omniflow II vascular prostheses in patients with or at a high risk of vascular graft infection is advisable, and is associated with acceptable reinfection and patency rates.

Abstract
OBJECTIVE Compared to canal wall up (CWU) tympanoplasty, canal wall reconstruction (CWR) allows better visualization of cholesteatoma extension. The canal wall up approach provides good functional outcomes, but with higher rates of residual cholesteatoma. The aim of this study was to compare residual cholesteatoma prevalence and location between the two approaches. METHOD Subjects were adult patients with residual cholesteatoma following CWU or CWR surgery between January 1, 2010 and December 31, 2015. During this period, 94 patients underwent CWU and 71 CWR; 22 presented with residual cholesteatoma: 16 after CWU (R-CWU group) and 6 after CWR (R-CWR group). RESULTS There was no significant inter-group difference in residual cholesteatoma prevalence: 17% after CWU, 8.4% after CWR. Locations comprised: 13 (81%) in the attic, 9 (56%) in the tympanic cavity and 4 (25%) in the mastoid in the R-CWU group, and 6 (100%) in the attic in the R-CWR group. There were significantly fewer tympanic cavity locations after CWR compared to CWU (P=0.046). CONCLUSION Residual cholesteatoma prevalence did not significantly differ between the CWU and CWR approaches. The most frequent location was the attic; significantly more locations were in the tympanic cavity with the CWU approach. These findings are important for surgeons and neuro-radiologists during follow-up.

Abstract
Introduction The Kerecis™ Omega3 Wound matrix is a decellularized skin matrix derived from fish skin and represents an innovative concept to achieve wound healing. The aim of this study was to report the cumulative experience of three centers for vascular surgery regarding use of the Omega3 Wound matrix in selected patients with complicated wounds. Material and methods In this study 23 patients with 25 vascular and/or diabetes mellitus-associated complicated wounds and partially exposed bony segments were treated with the Omega3 Wound matrix in three vascular centers. In several patients, conventional wound treatment with vacuum therapy had previously been carried out sometimes over several weeks without durable success. Following initial debridement in the operating room, the matrix was applied and covered with a silicone mesh. In the further course, wound treatment was conducted on an outpatient setting if possible. Results In total 25 wounds were treated with localization at the level of the thigh (n = 2), the distal calf (n = 7), the forefoot (n = 14) and the hand (n = 2). The time to heal varied between 9 and 41 weeks and between 3 and 26 wound matrices were applied per wound. Interestingly, a reduction of analgesics intake was noted when the treatment with the Omega3 Wound matrix was initiated. Conclusion The novel Omega3 Wound matrix in this study represented an effective treatment option in 25 complicated wounds. Further studies are necessary to evaluate the impact of the wound matrix on stimulation of granulation tissue and re-epithelialization as well as the potential antinociceptive and analgetic effects.

A simple laboratory algorithm for diagnosis of melioidosis in resource-constrained areas: a study from north-central Vietnam. Clin Microbiol Infect 2017; 24:84.e1-84.e4. [PMID: 28780059 DOI: 10.1016/j.cmi.2017.07.029] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2017] [Revised: 06/26/2017] [Accepted: 07/26/2017] [Indexed: 01/25/2023]
Abstract
OBJECTIVES Melioidosis may be endemic in many tropical developing countries, but diagnosis of the disease is currently unreliable in resource-limited areas. We aimed to validate a simple and cheap laboratory algorithm for the identification of Burkholderia pseudomallei from clinical specimens in parts of Vietnam where the disease has not previously been reported. METHODS In June 2015, we conducted training courses at five general hospitals in north-central provinces in order to raise awareness of the disease and to introduce a simple and cheap laboratory identification algorithm for B. pseudomallei including the three-antibiotic disc test. RESULTS Until the end of the year (7 months later), 94 suspected B. pseudomallei strains resistant to gentamicin and colistin but sensitive to amoxicillin/clavulanic acid were detected in clinical specimens from 70 patients. All strains were further confirmed as B. pseudomallei by using a specific TTSS1 real-time PCR assay and recA sequencing analysis. Among positive blood cultures, positive rates with B. pseudomallei ranged from 3.4% (5/147) to 10.2% (32/312) in the various clinics. A total of 82.8% (58/70) patients were bacteraemic, with a mortality of 50% (18/36) among patients with known outcome. No death occurred in nonbacteraemic patients. CONCLUSIONS Our results demonstrate that the introduction of a simple and easy-to-perform laboratory algorithm for the identification of B. pseudomallei from clinical samples, together with clinical awareness raising, can lead to the diagnosis of a significant number of melioidosis cases in resource-limited clinical laboratories which previously did not identify the pathogen.

Long-term results of transanal endoscopic microsurgery after endoscopic polypectomy of malignant rectal adenoma. Tech Coloproctol 2017; 21:225-232. [PMID: 28251355 DOI: 10.1007/s10151-017-1595-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2016] [Accepted: 02/02/2017] [Indexed: 01/26/2023]
Abstract
BACKGROUND There is no consensus on the treatment and prognosis of malignant rectal polyps. The aim of the present study was to determine the role of transanal endoscopic microsurgery (TEM) after endoscopic complete polypectomy of malignant rectal adenomas with long-term follow-up. METHODS Of 105 patients with pT1 rectal carcinoma in 32 patients TEM followed complete endoscopic polypectomy while 73 had primary TEM. Local recurrence (LR), distant metastasis, overall and cancer-specific survival were determined by the Kaplan-Meier method. RESULTS Median follow-up was 9.1 years. In 32 patients with TEM following complete polypectomy no residual cancer was found. LR occurred in 3/28 (11%) patients with low-risk carcinoma (pT1 G1/2/X, L0/X, R0) and in 1/4 (25%) with high-risk carcinoma (pT1 G3/4 or L1). After primary TEM with complete resection (minimal distance >1 mm) LR occurred in 6/60 (10%) with low-risk carcinoma. After incomplete TEM resection (minimal distance ≤1 mm) LR occurred in 3/8 (38%) patients with low-risk and in 1/5 (20%) patients with high-risk carcinoma. Grading was the only significant risk factor for LR after endoscopic polypectomy followed by TEM (p = 0.002). At all outcomes did not differ between postpolypectomy TEM and primary TEM. CONCLUSIONS Patients with malignant rectal polyps removed by endoscopic polypectomy have a substantial risk of LR even if TEM of polyp site is cancer free. Risk of LR depends on tumor characteristics. In low-risk carcinoma long-term follow-up is necessary. The high LR rate in patients with high-risk rectal carcinoma restricts the use of TEM alone.

Antibacterial activity of Litsea cubeba (Lauraceae, May Chang) and its effects on the biological response of common carp Cyprinus carpio challenged with Aeromonas hydrophila. J Appl Microbiol 2016; 121:341-51. [PMID: 27124660 DOI: 10.1111/jam.13160] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Revised: 02/17/2016] [Accepted: 04/21/2016] [Indexed: 12/17/2022]
Abstract
AIMS The aims of this study were to characterize the antibacterial activity and the chemotype of Litsea cubeba leaf essential oil (EO) harvested in North Vietnam and to investigate the biological effects induced by the leaf powder on growth, nonspecific immunity and survival of common carp (Cyprinus carpio) challenged with Aeromonas hydrophila. METHODS AND RESULTS The EO showed the prevalence of linalool (95%, n = 5). It was bactericidal against the majority of tested strains, with minimum inhibitory concentrations ranging from 0·72 to 2·89 mg ml(-1) (Aer. hydrophila, Edwarsiella tarda, Vibrio furnissii, Vibrio parahaemolyticus, Streptococcus garvieae, Escherichia coli, Salmonella Typhimurium). The fish was fed with 0 (control), 2, 4 and 8% leaf powder supplementation diets for 21 days. Nonspecific immunity parameters (lysozyme, haemolytic and bactericidal activities of plasma) were assessed 21 days after feeding period and before the experimental infection. Weight gain, specific growth rate and feed conversion ratio were improved by supplementation of L. cubeba in a dose-related manner, and a significant difference appeared at the highest dose (8%) when compared to the control. The increase in plasma lysozyme was significant for all the treated groups. Haemolysis activity was higher for the groups fed with 4 and 8% plant powder. Antibacterial activity increased significantly for the 8% dose only. CONCLUSIONS Litsea cubeba leaf powder increased nonspecific immunity of carps in dose-related manner. After infection with Aer. hydrophila, survivals of fish fed with 4 and 8% L. cubeba doses were significantly higher than those fed with 2% dose and the control. SIGNIFICANCE AND IMPACT OF THE STUDY A range of 4-8% L. cubeba leaf powder supplementation diet (from specific linalool-rich chemotype) can be used in aquaculture to reduce antibiotic burden and impacts of diseases caused by Aer. hydrophila.

Abstract
The formation of monocyte-platelet aggregates and neutrophil-platelet aggregates (MPA and NPA, respectively) is influenced by inflammation, but also might contribute to an exacerbation of inflammatory responses in atherosclerotic plaque. The purpose of this study was to analyze MPA and NPA proportions in regard to different stages of peripheral arterial disease (PAD). Forty-five patients with intermittent claudication (IC) (3 groups: Rutherford (R)-1, R-2, and R-3; each n = 15), 20 patients with critical limb ischemia (CLI) (Rutherford 5 (40%) and 6 (60%)), and 20 healthy controls were studied. Analyses of monocyte (Mon) subpopulations (CD14++CD16- (classical) Mon1, CD14++CD16+ (intermediate) Mon2, CD14+CD16++ (non-classical) Mon3), MPA, and NPA was performed from whole blood by flow cytometry. Controls showed an increased proportion of the Mon1 subpopulation (p < 0.001), whereas CLI patients showed a significant increase of the Mon2 subpopulation compared to controls, R-1, or R-2 patients (p < 0.0001). For the Mon3 subpopulation, CLI and R-3 patients showed an increased proportion (p < 0.05). MPA formation with the proinflammatory Mon2 and Mon3 subpopulations was increased in CLI patients (both p < 0.01). Similarly, NPA was significantly increased in CLI patients (p < 0.05). Serological markers of inflammation and procoagulation (fibrinogen [r = 0.459, p < 0.001], soluble triggering receptor expressed on myeloid cells (sTREM-1) [r = 0.237, p < 0.05] and P-Selectin [r = 0.225, p < 0.05]) correlated directly with MPA formation on the Mon2 subpopulation. We found an association of inflammatory and procoagulatory markers with increased formation of MPA on the Mon2 subpopulation. Since R-3 patients also had significantly increased MPA, one can speculate that the inflammatory burden might promote an aggravation of the disease.

Abstract
Thermodynamic equilibrium for adsorption means that the chemical potential of gas and adsorbed phase are equal. A precise knowledge of the chemical potential is, however, often lacking, because the activity coefficient of the adsorbate is not known. Adsorption isotherms are therefore commonly fitted to ideal models such as the Langmuir, Sips or Henry models. We propose here a new procedure to find the activity coefficient and the equilibrium constant for adsorption which uses the thermodynamic factor. Instead of fitting the data to a model, we calculate the thermodynamic factor and use this to find first the activity coefficient. We show, using published molecular simulation data, how this procedure gives the thermodynamic equilibrium constant and enthalpies of adsorption for CO2(g) on graphite. We also use published experimental data to find similar thermodynamic properties of CO2(g) and of CH4(g) adsorbed on activated carbon. The procedure gives a higher accuracy in the determination of enthalpies of adsorption than ideal models do.

Abstract
This study aimed to define the co-expression pattern of target receptor tyrosine kinases (RTKs) in human esophageal adenocarcinoma and squamous cell cancer. The co-expression pattern of vascular endothelial growth factor receptor (VEGFR)1-3, platelet-derived growth factor receptor (PDGFR)alpha/beta and epidermal growth factor receptor 1 (EGFR1) was analyzed by RT-PCR in 50 human esophageal cancers (35 adenocarcinomas and 15 squamous cell cancers). In addition, IHC staining was applied for the confirmation of the expression and analysis of RTK localisation. The adenocarcinoma samples revealed VEGFR1 (97%), VEGFR2 (94%), VEGFR3 (77%), PDGFRalpha (91%), PDGFRbeta (85%) and EGFR1 (97%) expression at different intensities. Ninety-four percent of the esophageal adenocarcinomas expressed at least four out of six RTKs. Similarly, squamous cell cancers revealed VEGFR1 (100%), VEGFR2 (100%), VEGFR3 (53%), PDGFRalpha (100%), PDGFRbeta (87%) and EGFR1 (100%) expression at different intensities. All esophageal squamous cell carcinomas expressed at least four out of six RTKs. While VEGFR1-3 and PDGFRalpha and EGFR1 was expressed by tumor cells, PDGFRbeta was restricted to stromal cells, which also depicted a PDGFRalpha expression. Our results revealed a high rate of RTK co-expression in esophageal adenocarcinoma and squamous cell cancer and may encourage application of multi-target RTK inhibitors within a multimodal concept as a promising novel approach for innovative treatment strategies.

Abstract
INTRODUCTION Conventional adrenalectomy still plays an important role, even in the era of minimally invasive endocrine surgery. It was the aim of our study to analyse the indications for conventional adrenalectomy in our own patients since the introduction of the minimally invasive technique in the year 1994 - laparoscopically and retroperitoneoscopically. PATIENTS AND METHODS Between January 1994 and September 2006, a total of 412 adrenalectomies were performed in 380 patients. Out of these, 106 operations (25.7 %) were carried out conventionally in 98 patients, and 306 operations (74.3 %) endoscopically in 282 patients. RESULTS Indications for conventional adrenalectomy were - as compared with the minimally invasive procedure - significantly more frequent adrenocortical carcinomas (ACC), especially in the context of multivisceral resections, as well as adrenal metastases (synchronous and metachronous). In contrast, adrenal Cushing's disease (including 19 patients with bilateral tumours), pheochromocytoma, incidentaloma and Conn's syndrome constituted a more frequent indication for minimally invasive adrenalectomy. Conventionally operated adrenal pathologies with on average 6.0 (range: 1.2-19.0) cm diameter were significantly larger than the endoscopically removed tumours with on average 3.3 (range: 0.2-9.2) cm diameter (p < 0.0001). The side localisation and the frequency of bilateral adrenal tumours did not differ significantly in the two groups. CONCLUSION Since the establishment of the minimally invasive technique in 1994, conventional adrenalectomy has been selected for 26 % of all resected adrenal pathologies at our clinic and, therefore, still plays an important role even in the era of laparoscopic surgery. The benefit of the laparoscopic procedure in the case of malignant pheochromocytoma, adrenocortical carcinoma, and isolated adrenal metastases at a locally confined stage is still unclear and requires prospective, randomised studies.

Abstract
HISTORY Patient 1 (female, aged 55 years) had for some time complained of morning nausea. She reported symptoms of reflux with regurgitation of food for two-and-a-half years and also dysphagia with retrosternal bolus obstruction for the last eighteen months. Patient 2 (male, aged 84 years) complained of restrosternal dysphagia with each intake of food for one year, weight loss of 12 kg and occasional regurgitation of food. INVESTIGATIONS The general condition of patient 1 was only slightly impaired but that of patient 2 markedly reduced. Routine laboratory tests were unremarkable in both. Barium meal in patient 1 revealed fixed narrowing in the region of the esophageal hiatus. The inferior esophageal sphincter was closed but opened under pressure during esophagogastroscopy. At computed tomography (CT) of the thorax and abdomen an esophageal fistula was detected and bronchoscopy confirmed its opening into the esophagus. Barium meal in patient 2 (done at another hospital) demonstrated a spastic esophagus. Manometry of the esophagus revealed at rest an abnormal increase in the inferior esophageal sphincter without relaxation. DIAGNOSIS, TREATMENT AND COURSE Patient 1 had an achalasia and an esophagogastric fistula with recurrent aspiration pneumonia, bronchial carcinoma being excluded. The fistula was closed by suture, followed by cardiomyotomy and anterior partial gastric fundectomy. In patient 2 an isolated achalasia had at first been suspected and botulinum toxin injected into the inferior esophageal sphincter. This caused a progressively worse dysphagia. CT of the thorax and abdomen established the diagnosis of a pseudoachalasia due to an adenoma of the cardia, proven by biopsy at an exploratory laparotomy. A stent was implanted in the esophagus: the postoperative course was without complication. CONCLUSION Patient 2 with the pseudoachalasia had a relatively short history of dysphagia, marked weight loss and was elderly. This compares with the history in patient 1: shorter period of dysphagia, no weight loss and a younger age. The differential diagnosis between the two conditions may be difficult with routine methods and other imaging modalities: exploratory surgery may be necessary for a definitive diagnosis.

Abstract
The laparoscopic management of the intrathoracic stomach is still controversial. Laparoscopic semifundoplication in gastroesophageal reflux disease results in effective long-term reflux control and is, as compared with 360° Nissen fundoplication, associated with less frequent side effects such as dysphagia and gas bloat syndrome. The aim of our study was to evaluate the results of laparoscopic anterior semifundoplication in patients with intrathoracic stomach. Enrolled in this study are 19 patients (67.1 years of age; range, 37.5–83.7 years) with intrathoracic stomach undergoing laparoscopic anterior semifundoplication and a minimal follow up of 5 months postoperatively. The study covers the interval between August 1999 and March 2006. Including criterion was a minimum percentage of herniated intrathoracic stomach of 33 per cent. A standardized questionnaire was used for follow up and the modified symptomatic DeMeester score (0–9) was assessed. The median percentage of herniated stomach in the chest was 87.5 per cent (range, 33–100%). Seven patients revealed organo-axial volvulus of the stomach. Duration of preoperative symptoms was 24 months (range, 1–266 months) with a median follow up of 18 months (range, 5–76 months) postoperatively. The modified symptomatic DeMeester score was 0 (0–3). Thirteen of 19 patients were on no postoperative proton pump inhibitor medication. One patient had anatomic recurrence on late follow up at 27 months. The overall contentment with the surgical treatment on an analog scale from 0 to 10 was a median of 9. Although laparoscopic anterior semifundoplication yields satisfactory symptomatic results in patients with intrathoracic stomach, the incidence of failures and anatomical recurrences is higher than expected from subjective data. Prospective, randomized long-term studies are essential to gain further information about the “ideal” type of laparoscopic repair in large hiatal hernia with intrathoracic stomach.

Abstract
BACKGROUND The aim of this study was to evaluate long-term results of laparoscopic anterior semifundoplication in patients with nonerosive (NERD) and erosive (ERD) gastroesophageal reflux disease. PATIENTS AND METHODS The study includes the period from May 1997 to July 2005. Upper gastrointestinal endoscopy was performed in all 190 patients. The severity of reflux esophagitis was classified according to Savary and Miller (grades I-IV). A standardized questionnaire was used for follow-up, and the modified symptomatic DeMeester score was assessed. RESULTS 58.5 years of age (range 27-80), patients with nonerosive reflux disease (n=83) were significantly older than those with erosive reflux disease (n=107) (48 years range 15-84) (p=0.0001). Patients with NERD had a lower modified symptomatic DeMeester score postoperatively of 0 (range 0-4) than patients with ERD, of 1 (range 0-5), though without statistical significance (p=0.151). CONCLUSION Laparoscopic anterior semifundoplication leads to comparable symptomatic long-term results in both NERD and ERD. Anterior semifundoplication is a good therapeutic option for selected patients with persistent reflux-associated symptoms and endoscopically negative esophagitis.

Abstract
HISTORY A 65-year-old patient underwent transesophageal echocardiography which caused a perforation of the upper esophagus. Three months after esophagostomy and gastrostomy the reconstruction was accomplished by a colon interposition graft. The patient postoperatively developed an ischemic necrosis of the graft, followed by a cervical fistula. Food intake and swallowing became impossible. DIAGNOSIS X-ray examinations revealed the cervical fistula and a stenotic colon graft. TREATMENT AND COURSE The retrosternal colon graft was replaced by a gastric interposition graft, which was anastomosed with the cervical esophagus. The postoperative follow-up was normal at first. Increasing retention of secretion in the remaining esophagus however caused dilatation and a cervival fistula again, as well as a pleural empyema. After transthoracic resection of the esophagus the patient was finally free of symtoms, and gained weight on unrestricted food intake. CONCLUSION Transesophageal echocardiography is a common diagnostic procedure with a low complication rate. Even though serious complications may occur in rare cases, the patient must be informed about the risk. The perforation of the esophagus is an emergency situation that requires surgical treatment immediately. Primary reconstruction and preservation of the esophagus is the recommended strategy.

Abstract
BACKGROUND This study examined the effect of anterior partial fundoplication on reflux symptoms and dysphagia in gastroesophageal reflux disease. PATIENTS AND METHODS Perioperative results in 249 patients were evaluated retrospectively for 93 conventional and prospectively for 156 laparoscopic procedures. The patients were followed up by standardized questionnaire. Median clinical follow-up period was 9 months (range 6-44) after laparoscopic and 88 months (range 15-194) following partial open fundoplication. RESULTS The median operating time was 58 and 115 min for laparoscopic and open partial fundoplication. Intraoperative complications were rare (1%) for both approaches. After introduction of the laparoscopic procedure the morbidity rate was reduced (mean 3.2% vs. 1.3%) at a shorter postoperative hospital stay (10 vs. 5 days). No reflux symptoms were found in 71.4% patients after conventional and in 69% after laparoscopic partial fundoplication, dysphagia did not develop in 86% and 85%, respectively, and 66% and 82% received no medications. Among the patients with reflux symptoms 6.5% and 0.9% underwent revision surgery. Satisfaction with the surgical outcome was expressed by 78% and 85% of patients, respectively. CONCLUSIONS Anterior partial fundoplication achieves effective medium- and long-term control of reflux symptoms. Technically easy to perform and associated with few complications, the procedure is superior to fundoplication with respect to the development of postoperative dysphagia and therefore represents a viable alternative to fundoplication.

Abstract
INTRODUCTION According to randomized studies, semifundoplication in the treatment of gastroesophageal reflux disease (GERD) is related to lower postoperative dysphagia rates than with fundoplication in comparable reflux controls. However there is a lack of long-term results. The object of this study was therefore to determine the influence of partial anterior fundoplication on the long-term clinical outcome (>1 year) in patients with GERD. METHOD From December 1986 until May 2000, 100 patients suffering from GERD were operated on. Seven of them were not evaluated, four because of revisional surgery, two because of preceding multiple abdominal operations (MEN, colitis ulcerosa), and one because of Nissen fundoplication. In all, the perioperative results of 93 patients (51 men and 42 women aged 21 to 86 years) were evaluated. Fourteen patients died during the follow-up period and two were lost because of changes in address. Thus, 77 patients with a median follow-up of 88 months (range 15-94) were interviewed with a list of standardized questions concerning reflux control and dysphagia. RESULTS The median operation time was 110 m (range 55-270). In one patient, an esophageal mucosal tear was detected intraoperatively and promptly repaired. Postoperatively, 71.4% (55/77) had no reflux complaints, 85.7% (66/77) had dysphagia, 66.2% took no further medication, and 31.2% (24/77) continued taking medication. The median interval free of symptoms was 25.5 months, and in 40.9% of the patients, symptoms recurred within the first year after operation. Five patients were in need of reoperation. A total of 77.9% of the patients were satisfied with the results of the operation. CONCLUSIONS With regard to reflux control, long-term results of anterior semifundoplication are comparable to those of fundoplication. However, considering postoperative dysphagia, the technically easier anterior semifundoplication is less eventful and therefore a good alternative which in the long run shows good results after laparoscopic intervention.
