Laparoscopic antireflux surgery for gastroesophageal reflux disease: experience with 668 laparoscopic antireflux procedures.

BACKGROUND AND AIMS: In the past decade laparoscopic antireflux surgery has become the standard operation for treating severe gastroesophageal reflux disease. Several studies have been published showing that it can achieve good to excellent results at short- and medium-term follow-up. We present our experience with 668 laparoscopic antireflux procedures. PATIENTS AND METHODS: Between September 1993 and July 2001 we performed 668 laparoscopic antireflux procedures (76% laparoscopic 360 degrees "floppy" Nissen fundoplications in patients with normal esophageal motility, 24% laparoscopic 270 degrees Toupet partial fundoplications in patients with poor esophageal motility or severely disordered peristalsis). Patients with achalasia were excluded from analysis. Preoperative and postoperative data including 24-h pH monitoring, esophageal manometry, and analysis of failure were prospectively reviewed. RESULTS: Overall complication rate was 7.6%. Conversion to open surgery was necessary in five patients (0.8%). Seventy-four laparoscopic redo procedures were performed due to failed primary intervention. There was no death. At a mean follow-up of 4.8 years (range 3-94 months) 24-h pH monitoring and esophageal manometry showed normal values in 93% of patients. CONCLUSION: Laparoscopic antireflux surgery is feasible and effective and can be performed safely without mortality and low morbidity with good to excellent functional and symptomatic results.

Customized biofeedback therapy improves results in fecal incontinence.

BACKGROUND AND AIMS: Biofeedback therapy has been extensively used and accepted in fecal incontinence, but reports of its efficiency vary. We evaluated feedback therapy efficiency when (a) selecting the patient's subject of the therapy, and (b) customizing the therapy protocol used for each patient. PATIENTS AND METHODS: Fifty-three patients with fecal incontinence were selected for biofeedback training. The treatment program was customized for each patient depending on the underlying dysfunction, the patient's cooperative and learning attitude, and the patient's progress. Biofeedback efficiency was measured using clinical scores, subjective satisfaction of the patient, and manometry. RESULTS: Incontinent scores showed improvement in 66% of patients and good improvement in 11% and 15%, respectively, indicating an overall excellent effect of the therapy. Subjective satisfaction was strongly correlated with the previous incontinent scores. Comparison of manometry parameters before and after biofeedback therapy, including maximum anal resting, maximum anal squeeze pressure, and maximum duration of the squeeze, all showed significant differences. In addition, the sensory threshold significantly decreased after biofeedback therapy. Clinical improvements were maintained during the following 12 months. CONCLUSION: Biofeedback improves objective and subjective parameters of anorectal function. Selection of patients and customization of the therapy program increased biofeedback efficiency for the treatment of fecal incontinence.

Prospective clinical and manometric study of fistulotomy with primary sphincter reconstruction in the management of recurrent complex fistula-in-ano.

BACKGROUND AND AIMS: The aim of this study was to assess the results of fistulotomy with sphincter reconstruction in the management of recurrent complex fistula-in-ano in terms of recurrence and continence. PATIENTS AND METHODS: Prospective study of 16 patients undergoing fistulotomy with sphincter reconstruction for recurrent complex fistula-in-ano was done. Preoperative and postoperative evaluation included physical examination, anal ultrasonography and anal manometry, with a 40-month follow-up. The Wexner Continence Grading Scale (0-20) was used to assess faecal continence. RESULTS: Fistulas were classified as high transsphincteric in 13 patients (81.3%), suprasphincteric in 2 (12.5%) and extrasphincteric in 1 patient (6.2%). Four patients (25%) had recurred twice or more. Eight patients (50%) complained of varying degrees of prior faecal incontinence. Their mean score decreased from 8.5 to 1.875 after surgery, and all the patients improved except for one whose score remained the same. On anal manometry, the differences between continent and incontinent patients before surgery [maximum resting pressure (MRP) 86.3 vs 57.6 mmHg, maximum squeeze pressure (MSP) 196.5 vs 138.6 mmHg] decreased after surgery (MRP 81.9 vs 63.7 mmHg, MSP 179.8 vs 159.3 mmHg). In fully continent patients, both the clinical score and manometric values were quite similar after surgery. Two fully continent patients (25%) developed occasional flatus incontinence and soiling, scoring two and three points, respectively. One patient recurred (6.25%) 6 months after surgery. CONCLUSION: Fistulotomy with sphincter reconstruction seems to be an effective resource in the management of recurrent complex fistula-in-ano. It improves both anal continence and manometric values in incontinent patients without compromising them in fully continent ones.

Ultrasonographic patterns in patients with obstructed defaecation.

BACKGROUND: Anal ultrasound is helpful in assessing organic anorectal lesions, but its role in functional disease is still questionable. The purpose of the present study is to assess anal-vaginal-dynamic perineal ultrasonographic findings in patients with obstructed defecation (OD) and healthy controls. MATERIALS AND METHODS: Ninety-two consecutive patients (77 women; mean age 51 years; range 21-71) with symptoms of OD were retrospectively evaluated. All patients underwent digital exploration, endoanal and endovaginal ultrasound (US) with rotating probe. Forty-one patients underwent dynamic perineal US with linear probe. Anal manometry and defaecography were performed in 73 and 43 patients, respectively. Ultrasonographic findings of 92 patients with symptoms of OD were compared to 22 healthy controls. Anismus was defined on US when the difference in millimetres between the distance of the inner edge of the puborectalis muscle posteriorly and the probe at rest and on straining was less then 5 mm. Sensitivity and specificity were calculated by assuming defaecography as the gold standard for intussusception and rectocele and proctoscopy for rectal internal mucosal prolapse. Since no gold standard for the diagnosis of anismus was available in the literature, the agreement between anal US and all other diagnostic procedures was evaluated. RESULTS: The incidence of anismus resulted significantly higher (P < 0.05) in OD patients than healthy controls on anal (48 vs 22%), vaginal (44 vs 21%), and dynamic perineal US (53 vs 22%). A significantly higher incidence of rectal internal mucosal prolapse was observed in OD patients when compared to healthy controls on both anal (61.9 vs 13.6%, P < 0.0001) and dynamic perineal US (51.2 vs.9% P = 0.001). For the diagnosis of rectal internal mucosal prolapse, anal US had a 100% sensitivity and specificity. For diagnosis of rectal intussusception, anal US had an 83.3% sensitivity and 100% specificity and perineal US had a 66.6% sensitivity and 100% specificity. In the diagnosis of anismus, anal ultrasonography resulted in agreement with perineal and vaginal US, manometry, defaecography, and digital exam (P < 0.05). Other lesions detected by US in patients with OD include solitary rectal ulcer, rectocele and enterocele. Damage of internal and/or external sphincter was diagnosed at anal US in 19/92 (20%) patients, all continent and with normal manometric values. CONCLUSION: Anal, vaginal and dynamic perineal ultrasonography can diagnose or confirm many of the abnormalities seen in patients with OD. The value of the information obtained by this non-invasive test and its role in the diagnostic algorithm of OD is yet to be defined.

Pelvic floor dyssynergia and bimodal rehabilitation: results of combined pelviperineal kinesitherapy and biofeedback training.

Dyschezia may be caused by pelvic floor dyssynergia, which takes place when a paradoxical contraction or a failure to relax the pelvic floor muscles occurs during attempts to defecate. The aim of our study was to set up a new bimodal rehabilitation programme for pelvic floor dyssynergia, which combined pelviperineal kinesitherapy and biofeedback, and to evaluate the results of this treatment. Thirty-five patients (age range: 28-64 years; mean age: 42.5 years) from the outpatient unit of the Clinica Chirurgica of the University of Florence, Italy, and an age-matched group of 10 healthy control subjects (age range: 31-59 years; mean age 45.7 years) with normal bowel habits and without any defecatory disorders, were studied. The 35 patients were symptomatic for dyschezia without slow colonic transit and had been diagnosed as being affected by pelvic floor dyssynergia. No evidence of any organic aetiology was present but all demonstrated both manometric and radiological evidence of inappropriate function of the pelvic floor. All of the patients underwent bimodal rehabilitation, using the combined training programme Clinical evaluation, computerized anorectal manometry and defecography were carried out 1 week before and 1 week after a completed course in bimodal rehabilitation. The control group underwent manometric and defecographic examination. Their results were compared with those of the 35 patients before and after training. After the programme, all 35 patients had a very significant increase in stool frequency (P < 0.001), while laxative and enema-induced bowel movements had become significantly less frequent (P < 0.001). After bimodal rehabilitation, computerized anorectal manometry showed some peculiar results. Resting anal canal pressure had increased but not significantly. Pre-programme values that indicated a shorter duration ("exhaustio") of maximal voluntary contraction than found in the controls had returned to normal values. The rectoanal inhibitory reflex (RAIR), with incomplete relaxation, which had been shorter than that of controls, became normal by the end of the rehabilitation. All RAIR parameters were significantly different especially when pre- and post-treatment values were compared (P < 0.001). No differences were found as regards rectal sensation parameters and rectal compliance between those before or after bimodal rehabilitation. Defecographic pretreatment X-ray films showed indentation of the puborectalis and poor anorectal angle (ARA) opening, at evacuation, with trapping barium of at 50%. After pelviperineal kinesitherapy and biofeedback training, the indentation had disappeared and the ARA had become significantly larger (P < 0.001) during evacuation. No differences were found after rehabilitation, when both were compared with those of controls. The pelvic floor descent was also significantly deeper (P < 0.001) than before the start of the programme. The bimodal rehabilitation technique can be considered a useful therapeutic option for functional dyschezia as shown by our clinical evaluations, manometric data and defecographic reports.

A new grading of rectal internal mucosal prolapse and its correlation with diagnosis and treatment.

The management of rectal internal mucosal prolapse (RIMP) is not based on an accepted classification of the lesion which helps to choose the appropriate treatment. The aim of this prospective study was to report a new endoscopic grading of RIMP and to evaluate its clinical value. Thirty-two patients (7 men, 25 women; mean age 56 years, range 28-72) affected by symptomatic RIMP were prospectively classified as follows: RIMP was defined as first degree when detectable below the anorectal ring on straining, as second degree when it reached the dentate line, and as third degree when it reached the anal verge. Anal manometry was carried out in 26 patients, and anal ultrasound and defecography in 6 prior to surgery. A correlation was found between the occurrence and severity of symptoms and the degree of the prolapse as obstructed defecation, bleeding and fecal soiling affected mainly patients with third-degree RIMP. At manometry the maximal resting tone was 60+/-23 mm Hg and voluntary contraction 96+/-41 mm Hg (mean+/-SEM). At anal ultrasound the mean internal sphincter thickness was 2.1+/-0.2 mm, and external sphincter thickness was 7.0+/-0.8 mm. A significant rectocele and rectal intussusception (n = 2) and a nonrelaxing puborectalis muscle on straining (n = 2) were observed at defecography in cases with third-degree RIMP. The anorectal angle was 100+/-75 degrees at rest, 63+/-20 degrees on squeezing, and 115+/-9 degrees on straining. A conservative treatment with high-fiber diet and/or rubber band ligation was carried out in all cases of first and in most patients with second-degree RIMP (n = 26). Those who required surgery, i.e., stapled transanal excision of the prolapse (n = 6), had either severely symptomatic third-degree RIMP with solitary ulcer syndrome (n = 4) or second-degree RIMP (n = 2). A positive outcome was achieved in 71% of cases. The proposed classification evaluated by the present study may be of clinical value in managing rectal internal mucosal prolapse.

Rectoanal inhibition and rectocele: physiology versus categorization.

Some authors divide rectoceles into those with chronic evacuatory difficulty and normal genital position (type 1) and those with associated pelvic organ prolapse (type 2). This study assessed whether there are physiological differences between these two clinical rectocele types. Female patients were assessed by conventional anorectal manometry, vector manometry, parametric assessment of the rectoanal inhibitory reflex (RAIR), and defecography. Subjects included 33 volunteer controls without anorectal disease, 14 patients with type I rectocele, and 26 patients with type II rectocele. Significant differences were noted for resting pressure measurements (maximal resting anal pressure and vector volume) between rectocele types and between type I patients and controls. Significant differences were noted for squeeze parameters (maximal squeeze pressure and vector volume) only between rectocele types. There were minimal differences in parameters of the RAIR, with a reduced slope of inhibition in the proximal sphincter for both rectocele groups and a reduced maximal inhibitory pressure in the intermediate and distal sphincter of type 1 rectocele patients. There were no differences in transient excitation of the pressure wave during the RAIR reflex to account for pressure variations with no measured differences in rectocele depth (type 1, 2.87 +/- 0.7 cm; type 2, 2.84 +/- 1.4 cm) There are few physiological differences between the different clinical categories of rectocele patients based on the presence or absence of associated genital prolapse.

Effect of bolus consistency on swallowing--does altering consistency help?

The influence of food bolus consistency on the pharyngeal wave during swallowing was investigated using a four-sensor manometry probe in 22 healthy volunteers. Pharyngeal pressures were recorded for 5 ml boluses of water, pudding and buttered bread via a manometry probe placed transnasally. The distal sensor was sited within the upper oesophageal sphincter (UOS); the three proximal sensors were then located 2, 4 and 6 cm above the UOS. The amplitude and timing of the swallow waveforms for pudding and buttered bread were recorded and compared with those for water. Increased bolus viscosity led to increased amplitude of the bolus wave and clearing contraction within the pharynx. In the UOS, increased bolus viscosity was associated with a larger pressure nadir (sub-atmospheric pressure) on opening and intra bolus pressure during transit. Bolus consistency also influenced the coordination of the swallow response with delayed pharyngeal clearance. The putative relevance of these findings to dietary modification for patients with neurological and neuromuscular dysphagia is discussed.

Radiological evidence of subclinical dysphagia in motor neuron disease.

Dysphagia in motor neuron disease (MND) may lead to dangerous complications such as cachexia and aspiration pneumonia. Functional evaluation of the oropharyngeal tract is crucial for identifying specific swallowing dysfunctions and planning appropriate rehabilitation. As part of a multidisciplinary study on the treatment of dysphagia in patients with neuromuscular diseases, 23 MND patients with different degrees of dysphagia underwent videofluoroscopy, videopharyngolaryngoscopy and pharyngo-oesophageal manometry. The results of the three instrumental investigations were analysed in order (1) to define the pattern of swallowing in MND patients complaining of dysphagia; (2) to evaluate whether subclinical abnormalities may be detected; and (3) to assess the role of videofluoroscopy, videopharyngolaryngoscopy and manometry in the evaluation of MND patients with deglutition problems. Correlations between the instrumental findings and clinical features (age of the patients, duration and severity of the disease, presence and degree of dysphagia) were also assessed. The results of our study showed that: (1) The oral phase of deglutition was compromised most often, followed by the pharyngeal phase. (2) In all patients without clinical evidence of dysphagia, subclinical videofluoroscopic alterations were present in a pattern similar to that found in the dysphagic group. (3) Videofluoroscopy was the most sensitive technique in identifying oropharyngeal alterations of swallowing. Impairment of the oral phase, abnormal pharyngo-oesophageal motility and incomplete relaxation of the upper oesophageal sphincter were the changes most sensitive in detecting dysphagia. Videofluoroscopy was also capable of detecting preclinical abnormalities in non-dysphagic patients who later developed dysphagia. Practical guidelines for the use of instrumental investigations in the assessment and management of dysphagia in MND patients are proposed.

Comparison of colonic J-pouch reconstruction and straight coloanal anastomosis after intersphincteric rectal resection.

The tendency towards sphincter-preserving resection for distal rectal cancers has led to the technique of straight coloanal anastomosis (CAA) and colonic J-pouch anal anastomosis (CPA) after low anterior resection. The aim of the present study was to compare complication rate, anorectal physiology and functional results after both types of reconstruction after ultra-low intersphincteric resection. A total of 31 patients who had undergone CPA were followed up prospectively using anorectal manometry and a standardised questionnaire and were compared with 63 patients who had undergone CAA and were followed up in the same way. The complication rate after CPA did not differ significantly from that after CAA. One year postoperatively, the median stool frequency and urgency were reduced after CPA (1.7+/-2.2/day; 7% vs. 2.4+/-3.6/day; 14%; P<0.05). Three months after colostomy/ileostomy closure, the maximum tolerable volume, threshold volume and compliance were decreased after CAA when compared with CPA (55+/-12, 34+/-12, and 3.9+/-0.3 ml/mmHg vs. 85+/-21, 53+/-11 and 6.2 ml/mmHg, respectively; P<0.05). Anal manometry revealed no significant differences in the anal resting and squeeze pressure. One year postoperatively, continence also did not differ significantly between CPA and CAA. Colonic J-pouch reconstruction seems to be superior to the straight coloanal anastomosis, especially during the first postoperative year. In view of the often poor prognosis of the patients, it is the reconstruction of choice after ultra-low resections of the rectum.

Case report: botulinum toxin in hypertensive lower esophageal sphincter: a manometric case study.

The hypertensive lower esophageal sphincter (HLES) is a disorder of esophageal motility associated with dysphagia and chest pain. Although well characterized manometrically, opinions differ greatly with regard to its pathophysiology and its management. Therapy is limited to a few medications, esophageal dilatation, and even surgery, although none of these options are consistently successful. In this case report we describe a 54-year-old woman with HLES and dysphagia who was successfully treated with botulinum toxin injection of the lower esophageal sphincter (LES). Esophageal manometry after botulinum toxin therapy revealed normalization of LES pressures. Three months after therapy, symptoms returned and repeat esophageal manometry demonstrated the return of elevated LES pressures. This report is the only published case of botulinum toxin injection into the LES with both pre- and post-treatment esophageal manometric data. This case report is evidence that LES dysfunction produces symptoms in patients with HLES, and that reduction in LES pressure improves symptoms. Current pathophysiologic hypotheses for HLES-associated dysphagia and its treatment are briefly reviewed in this report.

Austrian experiences of antireflux surgery.

BACKGROUND: Antireflux surgery (ARS) is a well established treatment for GERD (gastroesophageal reflux disease). The present study gives an overview of experience in Austria regarding the frequency of open and laparoscopic ARS and how Austrian departments meet the requirements for surgery. METHODS: A questionnaire was sent to 115 surgical departments in Austria to evaluate in how many institutions antireflux surgery (open and/or laparoscopically) was performed since 1990, and which pre- and postoperative tests were obligatory, optional, or not performed. Units were divided into specialized and nonspecialized. RESULTS: The laparoscopic approach has gained in importance by about 300% in the past 5 years in the few hospitals performing this procedure. Esophageal manometry and 24-h pH monitoring were rarely done in nonspecialized units, despite the fact that GERD is mainly a functional disorder of the esophagus and stomach. In contrast to the nonspecialized units, the specialized unit performed upper endoscopy, esophageal manometry and 24-h esophageal pH monitoring as obligatory tests. CONCLUSIONS: ARS, both open and laparoscopic, is not commonly performed in surgical departments in Austria but the frequency has significantly increased in recent years. Laparoscopic ARS is a safe procedure in hospitals performing this frequently. Laparoscopic ARS should only be performed in specialized units with significant experience in gastroesophageal diseases, where functional testing of the esophagus can be done.

Nissen vs Toupet laparoscopic fundoplication.

BACKGROUND: Nissen fundoplication (360 degrees ) is the standard operation for the surgical management of gastroesophageal reflux disease (GERD). To avoid postoperative dysphagia, it has been proposed that antireflux surgery be tailored according to the degree of preexisting esophageal motility. Postoperative dysphagia is thought to occur more commonly in patients with esophageal dysmotility and the Toupet procedure (270 degrees ) has been recommended for these patients. We performed a randomized trial to evaluate this tailored concept and to compare the two operative techniques in terms of reflux control and complication rate (dysphagia). Our objective was to determine the impact of preoperative esophageal motility on the clinical and objective outcome, following Toupet vs Nissen fundoplication and to evaluate the success rate of these procedures. METHODS: From May 1999 until May 2000, 200 patients with GERD were included in a prospective randomized study. After preoperative examinations (clinical interview, endoscopy, 24-h pH study and esophageal manometry), 100 patients underwent either a laparoscopic Nissen (50 with and 50 without motility disorders), or a Toupet procedure (50 with and 50 without motility disorders). Postoperative follow-up after 4 months included clinical interview, endoscopy, 24-h pH study and esophageal manometry. RESULTS: Interviews showed that 88% (Nissen) and 90% (Toupet) of the patients, respectively, were satisfied with the operative result. Dysphagia was more frequent following a Nissen fundoplication than after a Toupet (30 vs 11, p <0.001) and did not correlate with preoperative motility. In terms of reflux control, the Toupet proved to be as effective as the Nissen procedure. CONCLUSION: Tailoring antireflux surgery to esophageal motility is not indicated, since motility disorders are not correlated with postoperative dysphagia. The Toupet procedure is the better operation because it has a lower rate of dysphagia and is as effective as the Nissen fundoplication in controlling reflux.

Tailored approach to Zenker's diverticula.

BACKGROUND: Zenker's diverticula (ZD) can be treated by diverticulostomy or open surgery (upper esophageal sphincter myotomy and diverticulectomy or diverticulopexy). The aim of this study was to compare the outcome of the two alternative treatments. METHODS: Fifty eight patients were scored for symptoms and upper esophageal sphincter (UES) pressure; relaxations and intrabolus pressures were recorded by manometry. Treatment depended on operative risk and ZD size. Twenty four patients with high surgical risk and/or a <3-cm or >5-cm pouch underwent diverticulostomy; the other 34 had open surgery. RESULTS: Mortality was nil. Five patients had postoperative complications after open surgery (p<0.05). Hospital stay was shorter after diverticulostomy (p<0.001). Follow-up (41 months; range, 1-101) was obtained in 53 patients. Postoperative manometry showed a UES pressure reduction, improved UES relaxation, and lower intrabolus pressure in both groups (p<0.05). In the diverticulostomy group, three patients complained of severe dysphagia. vs none in the open surgery group (p<0.05). CONCLUSION: Diverticulostomy is safe, quick, and effective for most patients with medium-sized ZD, but open surgery offers better long-term results and should be recommended for younger, healthy patients with small or very large diverticula.

First year experience of patients undergoing the Stretta procedure.

BACKGROUND: The Stretta procedure is a new, totally endoscopic treatment for GERD, where radiofrequency energy is delivered to the smooth muscle of the gastroesophageal junction. METHODS: Forty-one patients undergoing the Stretta procedure between August 2000 and August 2001 were prospectively evaluated. Under an IRB-approved protocol, patients were studied preoperatively and postoperatively with esophageal manometry, 24-h pH testing, SF12 surveys, and GERD-specific questionnaires (QOLRAD). RESULTS: Results are reported as mean +/- SEM. All procedures were performed on an outpatient basis; 33 were under conscious sedation and 8 were under general anesthesia. Prior to treatment, patients had a mean LES pressure of 25 +/- 2.4 mmHg, Johnson-Demeester score of 32.8 +/- 4.6 mmHg, and % time reflux 8.4 +/- 0.9%. The quality-of-life scores were significantly improved at 6 months: QOLRAD score increased from 3.7 +/- 0.2 to 5.1 +/- 0.2 (p = 0.002), SF12 mental score increased from 44.3 +/- 2.0 to 51.8 +/- 1.7 (p = 0.001), and SF12 physical score increased from 26.2 +/- 2.4 to 33.1 +/- 3.8 (p = 0.001). Eighteen patients returned for esophageal manometry and 24-h pH testing at a mean of 6.8 +/- 0.5 months. There was a significant decrease in esophageal acid exposure time (8.4 +/- 0.9% to 4.4 +/- 1.3%, p = 0.03) and Johnson-Demeester score (32.8 +/- 4.6 to 22.9 +/- 5.3, p = 0.04). There was no significant change in mean LES pressure (25.3 +/- 2.4 mmHg to 26.8 +/- 2.6 mmHg, p = 0.63). Twenty of 31 patients (65%) available for 6 months follow-up were completely off proton pump inhibitors. The only complication related to Stretta was a case of gastroparesis 10 days post-operatively that resolved completely. CONCLUSIONS: The Stretta procedure is a promising new endoscopic treatment for GERD. It significantly improves GERD symptoms and quality of life while eliminating the need for proton pump inhibitors in the majority of patients.

Transoral diverticulostomy with a modified Endo-Gia stapler: results after 4 years of experience.

BACKGROUND: The incidence of Zenker's diverticulum is low (2/100,000). Standard surgical treatment is cricopharyngeal myotomy with diverticulectomy. Various minimally invasive surgical approaches pursued recently have treated Zenker's diverticulum adequately. The functional minimally invasive therapy is performed alternatively using an Endo-Gia stapler inserted transorally to perform an esophageal diverticulostomia, or using thermal coagulation applied by a carbon dioxide (CO2) or argon plasma laser. The key to a successful procedure is adequate exposure of the diverticulum by insertion of a pharynx spreader before the surgery. METHODS: Since 1996, 31 patients who underwent minimally invasive diverticulostomies performed in our clinic have been included prospectively in the current study. All the patients were examined endoscopically before and after surgery. Furthermore, the intraesophageal and intragastric pressure was examined by transesophageal manometry, and the pH in the esophagus and stomach was determined by pH-metry. A barium swallow was performed to exclude leakage at the stapler suture line as proof of sufficient anastomoses. Manometry showed that the upper esophageal sphincter functioned normally before and after surgery. The results were compared with those of patients undergoing conventional procedures. RESULTS: The median follow-up period after resection of the diverticulum was 46 months. Both the Gastrointestinal Quality-of-Life Index (GQLI) (p < 0.001) and the modified dysphagia score (GHDS) increased significantly, indicating that the operations were successful. The minimally invasive procedure is faster than cricopharyngeal myotomy and significantly safer. It is better tolerated by patients, and they are discharged earlier. CONCLUSION: Transoral esophagodiverticulosomy has become the standard procedure for Zenker's diverticulum in the authors' department. The endoscopic minimally invasive approach proved to be safer than standard surgical procedures. It offers a significantly shorter operation time and postoperative hospital stay (p < 0.001).

Gastroesophageal flap valve is associated with gastroesophageal and gastropharyngeal reflux.

BACKGROUND: The endoscopic grade of the gastroesophageal flap valve (GEFV) is suggested to be a good predictor of reflux status. The aim of this study was to investigate the association of the GEFV and gastroesophageal and gastropharyngeal reflux. METHODS: A total of 364 patients (151 men and 233 women; mean age, 52.2 years) who underwent endoscopy, esophageal manometry, and ambulatory 24-h dual-probe pH monitoring were included. GEFV was graded I through IV using Hill's classification; then, GEFV was classified into two groups: a normal GEFV group (grades I and II) and an abnormal GEFV group (grades III and IV). Findings of endoscopy, esophageal manometry, and ambulatory pH monitoring were compared between the groups. RESULTS: Increased GEFV grade was significantly associated with an increased prevalence of both reflux esophagitis and Barrett's epithelium (P < 0.001). Lower esophageal sphincter pressure was significantly lower in the abnormal GEFV group than in the normal GEFV group (P < 0.001). All variables showing gastroesophageal reflux in the distal probe were significantly higher in the abnormal GEFV group than in the normal GEFV group (P < 0.001). In addition, all variables, except the supine time of pH < 4, showing gastropharyngeal reflux in the proximal probe were significantly higher in the abnormal GEFV group than in the normal GEFV group (P < 0.001). The frequency of gastroesophageal reflux disease and of gastropharyngeal reflux disease was significantly higher in the abnormal GEFV group than in the normal GEFV group (P < 0.001). CONCLUSION: Endoscopic grading of the GEFV is easy and provides useful information about the status of gastroesophageal and gastropharyngeal reflux.

Evaluating patients with anorectal incontinence.

Fecal incontinence is a devastating disability, and although this condition is widely accepted as a problem in the elderly, it is now becoming apparent that much younger age groups are also frequently affected. Thorough assessment of anorectal incontinence is very important to choosing the most appropriate treatment. Careful history-taking and physical examination can identify the cause of most cases of incontinence and are essential in every patient. Several incontinence scoring systems have been proposed to provide an objective measure of a subject's degree of fecal incontinence, but only one acknowledges the important contribution of the severity of symptoms to quality of life. The investigations used to evaluate anorectal physiology include anorectal manometry, anal endosonography, nerve stimulation techniques, electromyography, defecography, endoluminal magnetic resonance imaging, the saline continence test, and the balloon-retaining test. Although all of these tests are important, the most useful for patients with incontinence are anal manometry, anal endosonography, and the pudendal nerve terminal motor latency test, because they can identify anatomic or physiologic abnormalities for which there may be effective treatments.
