Abstract
Endoscopic balloon dilatation (EBD) and surgical intervention are two most common and effective treatments for gastric outlet obstruction. Correction of gastric outlet obstruction without the need for surgery is an issue that has been tried to be resolved in these decades; this management has developed with EBD, advanced treatments like local steroid injection, electrocauterization, and stent have been added recently. The most common causes of pediatric gastric outlet obstruction are idiopathic hypertrophic pyloric stenosis, peptic ulcer disease followed by the ingestion of caustic substances, stenosis secondary to surgical anastomosis; antral web, duplication cyst, ectopic pancreas, and other rare conditions. A complete clinical, radiological and endoscopic evaluation of the patient is required to make the diagnosis, with complimentary histopathologic studies. EBD are used in exceptional cases, some with advantages over surgical intervention depending on each patient in particular and on the characteristics and etiology of the gastric outlet obstruction. Local steroid injection and electrocauterization can augment the effect of EBD. The future of endoscopic treatment seems to be aimed at the use of endoscopic electrocauterization and balloon dilatations.

Choi WJ, Park JJ, Park J, Lim EH, Joo MK, Yun JW, Noh H, Kim SH, Choi WS, Lee BJ, Kim JH, Yeon JE, Kim JS, Byun KS, Bak YT. Effects of the temporary placement of a self-expandable metallic stent in benign pyloric stenosis. Gut Liver 2013; 7:417-22. [PMID: 23898381 PMCID: PMC3724029 DOI: 10.5009/gnl.2013.7.4.417] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2012] [Revised: 10/24/2012] [Accepted: 10/29/2012] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND/AIMS The use of self-expandable metallic stents (SEMS) is an established palliative treatment for malignant stenosis in the gastrointestinal tract; therefore, its application to benign stenosis is expected to be beneficial because of the more gradual and sustained dilatation in the stenotic portion. We aimed in this prospective observational study to evaluate the efficacy and safety of temporary SEMS placement in benign pyloric stenosis. METHODS Twenty-two patients with benign stenosis of the prepylorus, pylorus, and duodenal bulb were enrolled and underwent SEMS placement. We assessed symptom improvement, defined as an increase of at least 1 degree in the gastric-outlet-obstruction scoring system after stent insertion. RESULTS No major complications were observed during the procedures. After stent placement, early symptom improvement was achieved in 18 of 22 patients (81.8%). During the follow-up period (mean 10.2 months), the stents remained in place successfully for 6 to 8 weeks in seven patients (31.8%). Among the 15 patients (62.5%) with stent migration, seven (46.6%) showed continued symptomatic improvement without recurrence of obstructive symptoms. CONCLUSIONS Despite the symptomatic improvement, temporary SEMS placement is premature as an effective therapeutic tool for benign pyloric stenosis unless a novel stent is developed to prevent migration.

Outcomes of balloon dilation for the treatment of strictures after endoscopic submucosal dissection compared with peptic strictures. Surg Endosc 2013; 27:3237-46. [PMID: 23479256 DOI: 10.1007/s00464-013-2900-0] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2012] [Accepted: 02/15/2013] [Indexed: 01/14/2023]
Abstract
BACKGROUND The outcomes of balloon dilation for the treatment of strictures caused by endoscopic submucosal dissection (ESD) have not been evaluated previously. This study was designed to evaluate and compare the effectiveness and complications of balloon dilation for post-ESD strictures and peptic strictures. METHODS The medical records of 14 patients with post-ESD strictures and 48 patients with peptic strictures who underwent fluoroscopically or endoscopically guided balloon dilation between January 1997 and April 2011 at the Asan Medical Center in Korea were reviewed retrospectively. RESULTS The technical success rates (defined as successful dilation without major complications) of the post-ESD and peptic stricture groups were 92.9% (13/14) and 93.8% (45/48), respectively (p = 1.000). For the post-ESD and peptic stricture groups, the clinical success rates (defined as symptom improvement, as determined by the patient) at 1 month were 92.9% (13/14) and 83.3% (40/48), respectively (p = 0.67). Their clinical success rates at 6 months were 71.4% (10/14) and 70 % (28/40), respectively (p = 1.000). The mean weight gains of the post-ESD stricture group 1 and 6 months after balloon dilation were 1.1 and 4.8 kg, respectively, whereas the peptic group gained 1.4 and 3.4 kg, respectively (p = 0.814). All complications were perforations. The complication rates of the post-ESD and peptic stricture groups were 7.1 % (1/14) and 10.5 % (5/48), respectively (p = 1.000). CONCLUSIONS Balloon dilation is an effective and safe treatment for post-ESD strictures.

Abstract
BACKGROUND AND STUDY AIMS Corrosive ingestion is common in Asia and it is a frequent cause of morbidity secondary to intense fibrotic reaction and stricture formation of the oesophagus. Isolated corrosive pyloric stenosis without oesophageal involvement is an uncommon phenomenon. PATIENTS AND METHODS All consecutive patients, with corrosive ingestion in the last two decades, were reviewed and analysed. Eleven out of 201 patients with corrosive ingestion had isolated gastric outlet obstruction. RESULTS Patients' age ranged from 11 to 29 years with a male:female ratio of 1.75:1. All patients developed pyloric stenosis following ingestion of solution of acids. Barium study revealed complete/near-complete gastric outlet obstruction in all patients. On laparotomy, there was gastric dilatation in 10 patients, who underwent posterior gastrojejunostomy, whereas the stomach was contracted in one patient, and hence anterior gastrojejunostomy was performed. Seven patients were completely relieved of their symptoms; persistent postprandial epigastric fullness and/or dyspepsia was observed in four patients whose gastrojejunostomy stoma was found adequate on barium study, suggestive of gastric motility disorder. We did not encounter gastrojejunostomy-related complication of stomal ulcer/stenosis in our patients. CONCLUSION Isolated corrosive pyloric stenosis is not as rare as is commonly thought. Gastrojejunostomy is effective, although a fair percentage of patients appear to develop gastric motility disorder secondary to corrosive injury.

Abstract
BACKGROUND Endoscopic balloon dilatation (EBD) is a therapeutic option for intestinal strictures of Crohn's disease (CD). Double-balloon endoscopy (DBE) enables EBD to be performed even for deep-situated strictures of the small intestine. The aim of this study was to clarify the efficacy and safety of EBD using DBE for small bowel strictures in patients with CD. PATIENTS AND METHODS The subjects comprised 25 patients with CD who underwent EBD using DBE for small intestinal strictures for which a colonoscope or gastrointestinal scope could not be inserted. All subjects had obstructive symptoms due to strictures that were confirmed using small intestinal enteroclysis. They were observed for at least 6 months after the initial EBD. The short-term success rate of EBD using DBE, the complication rate and the long-term outcome were investigated. RESULTS This procedure was successful with regard to short-term dilatation in 18 of the 25 CD patients (72%). Long strictures measuring more than 3 cm were seen in six out of seven (85.7%) of the unsuccessful EBD cases, compared with two out of 18 (11.1%) of the successful EBD cases (P=0.001). Complications were encountered in two of the 25 patients (8%). The cumulative surgery-free rate for all the subjects was 83% and 72% at 6 and 12 months, respectively. CONCLUSION EBD using DBE is a useful and safe procedure for small intestinal short strictures in CD patients. We conclude that this procedure is a therapeutic option that should be attempted before resorting to surgical therapy.

Abstract
BACKGROUND There are no reports on endoscopic balloon dilation (EBD) for caustic-induced gastric outlet obstruction (GOO) in the acute or subacute phase. OBJECTIVE To study the efficacy of early EBD in patients with caustic-induced gastric injury. SETTING Tertiary care center in India. DESIGN Retrospective analysis of data. PATIENTS Out of 41 patients with caustic-induced GOO who reported to us in the subacute phase between January 2001 and December 2008, 31 were treated by EBD. All 31 had ingested an acid 14.39 +/- 4.65 days earlier. EBD was achieved by using wire-guided balloons under endoscopic guidance. INTERVENTION The balloon was negotiated across the narrowed segment and inflated for 60 seconds using a pressure gun. Balloons of incremental diameter, up to a maximum of 3 sizes, were used in each sitting. Procedural success was defined as reaching the end point of dilation (15 mm) and absence of symptoms. RESULTS All 31 patients (18 male, mean age 32.06 +/- 11.04 years) could be successfully dilated. All but 1 underwent successful dilations to achieve the end point of 15 mm, requiring a median of 9 (range 3-18) dilations over a period of 7 (range 1.5-16) weeks. Complications included self-limiting pain (n = 10), bleeding at the time of the procedure (n = 9), and perforation in 1 patient (3.2%) who required surgery. Thirty patients were followed up for a median of 21 (range 3-72) months with no recurrence. CONCLUSION Early EBD by an expert endoscopist is a safe and effective treatment modality in the management of caustic-induced GOO.

Abstract
Gastric outlet obstruction (GOO) includes obstruction in the antropyloric area or in the bulbar or post bulbar duodenal segments. Though malignancy remains the most common cause of GOO in adults, a significant number of patients have benign disease. The latter include peptic ulcer disease, caustic ingestion, post-operative anastomotic state and inflammatory causes like Crohn’s disease and tuberculosis. Peptic ulcer remains the most common benign cause of GOO. Management of benign GOO revolves around confirmation of the etiology, removing the offending agent Helicobacter pylori (H. pylori), non-steroidal anti-inflammatory drugs, etc. and definitive therapy. Traditionally, surgery has been the standard mode of treatment for benign GOO. However, after the advent of through-the-scope balloon dilators, endoscopic balloon dilation (EBD) has emerged as an effective alternative to surgery in selected groups of patients. So far, this form of therapy has been shown to be effective in caustic-induced GOO with short segment cicatrization and ulcer related GOO. In the latter, EBD must be combined with eradication of H. pylori. Dilation is preferably done with wire-guided balloon catheters of incremental diameter with the aim to reach the end-point of 15 mm. While it is recommended that fluoroscopic control be used for EBD, this is not used by most endoscopists. Frequency of dilation has varied from once a week to once in three weeks. Complications are uncommon with perforation occurring more often with balloons larger than 15 mm. Attempts to augment efficacy of EBD include intralesional steroids and endoscopic incision.

Abstract
BACKGROUND The standard treatment of caustic-induced gastric outlet obstruction (GOO) is surgery. There are only a few reports in the medical literature on endoscopic balloon dilation (EBD) for caustic-induced GOO. OBJECTIVE To study the short-term and long-term response of EBD in patients with caustic-induced GOO. SETTING Tertiary-care center in India. DESIGN Retrospective analysis of data. PATIENTS Of the 49 patients with caustic-induced GOO seen by us between January 1998 and December 2003, 41 were treated by EBD. Thirty-seven patients had consumed an acid and 4 had consumed an alkali a mean (SD) of 19.5 +/- 14.5 weeks earlier. EBD was performed every 3 weeks by using through-the-scope balloons under endoscopic guidance. INTERVENTION The balloon was negotiated across the narrowed segment and inflated for 60 seconds by using a pressure gun. Balloons of incremental diameters, up to a maximum of 3 sizes, were used in each sitting. The end point of dilation was 15 mm, after which patients were assessed for recurrence. The patients were observed until August 2007. RESULTS All 41 patients (23 men; mean [SD] age 29.6 +/- 8.5 years) could be successfully taken for EBD. Thirty-nine patients underwent successful repeated dilations, which required a mean (SD) of 5.8 +/- 2.6 dilations (range 2-13) to achieve the end point of 15 mm. All 39 patients were followed up for an average (SD) of 35.4 +/- 11.1 months (range 18-58 months). The mean (SD) size of the first dilator was 8.2 +/- 0.6 mm (range 8-10 mm). One patient had a perforation and was subjected to antrectomy; another patient had pain every time he received EBD; he also had surgery. Other complications were minor: self-limiting pain (n = 8) or bleeding (n = 7). CONCLUSIONS EBD is a safe, effective, and long-lasting alternative to surgery for caustic-induced GOO.

Abstract
BACKGROUND Little is known about the advantages of laparoscopic truncal vagotomy with gastrojejunostomy (LTVGJ) over open truncal vagotomy with gastrojejunostomy (OTVGJ) for peptic pyloric stenosis (PPS). This study aimed to highlight the role of minimally invasive surgery in the form of LTVGJ for PPS. METHODS From March 1999 to October 2005, 21 patients with PPS underwent LTVGJ (n = 13) and OTVGJ (n = 8). We analyzed intraoperative and postoperative outcomes retrospectively. RESULTS Two groups had similar demographic characteristics. Significantly shorter operating time, hospital stay, time to presence of bowel sounds, and time to tolerate a diet were the advantages of LTVGJ, while blood loss was higher in OTVGJ. There were significant differences in weight gain between the two groups after surgery during follow-up. CONCLUSIONS This study suggests that LTVGJ is a feasible technique, and intermediate follow-up reveals good symptomatic results when used for PPS.

Abstract
PURPOSE OF REVIEW To examine the short and long-term success rates of balloon dilation of pyloric stenosis. RECENT FINDINGS Several large studies have demonstrated high rates of success for the relief of symptoms from pyloric stenosis using through-the-scope balloons. These dilating balloons readily increase the diameter of the stenotic pylorus on average from 6 to 16 mm. Patients who require more than two dilations are at high risk of endoscopic failure and the need for surgical intervention. Rapid re-stenosis rates are observed in patients with malignant pyloric obstruction. Since many patients with benign pyloric stenosis have underlying ulcer disease, helicobacter infection is a relatively common finding. Eradication of this infection at the time of balloon dilation will ensure higher long-term success rates. SUMMARY In summary, benign pyloric stenosis can be readily treated with endoscopic balloon dilation and should be the first-line therapy.

Abstract
INTRODUCTION Surgery has been the gold standard in the treatment of adult pyloric stenosis (APS). The introduction of proton pump inhibitors (PPIs) in 1989 revolutionised the treatment of peptic ulcer disease and its complications. PATIENTS AND METHODS We carried out a prospective study to evaluate the effectiveness of PPIs as an alternative to surgery for treatment of APS. Six consecutive patients admitted with a diagnosis of adult peptic pyloric stenosis between November 1999 and August 2002 were studied. The diagnosis was confirmed with endoscopy. All patients were commenced on a twice-daily dose of intravenous PPI. This was changed to oral treatment after 2 days. Main outcome measures evaluated were resolution of symptoms on PPIs and failure of medical therapy. RESULTS There were five females and one male. Median age at diagnosis was 72 years (range, 30-90 years). Median duration of symptoms was 2 weeks (range, 1-5 weeks). Of the patients, five had a history of peptic ulcer disease. Complete resolution was achieved in 5 patients (83%). Median duration for resolution of symptoms was 9 days (range, 5-14 days). All patients were changed to oral PPIs after 2 days. One patient did not respond to oral therapy and required surgical intervention (pyloroplasty). Median follow-up was 26 months (range, 6-48 months). There was no recurrence of symptoms. All patients were discharged on low-dose PPI. CONCLUSIONS This study supports the view that proton pump inhibitors are a safe and feasible alternative to surgery in adult pyloric stenosis secondary to peptic ulcer disease.

Abstract
BACKGROUND AND AIM Endoscopic balloon dilatation (EBD) has been used for the treatment of gastric outlet obstruction (GOO). There are several reports on the utility and success of this non-surgical treatment option in peptic GOO, with variable results. However, there are only a few reports documenting the efficacy of this method for non-peptic GOO. The authors here report on experience with balloon dilatation in peptic and non-peptic GOO over a 3-year period. METHODS Twenty-three patients with benign GOO underwent EBD. Dilatation was carried out with through-the-scope balloon dilators after premedication. Dilatation was repeated every week and the response was documented on the basis of symptoms and endoscopic findings and barium studies. Helicobacter pylori was eradicated in patients with peptic GOO, when present. RESULTS The 23 patients with GOO included 11 with peptic ulcer as the etiology, eight with corrosive-induced and four with chronic pancreatitis (alcohol three, idiopathic one). Patients with peptic GOO required 1-3 sessions (mean 2.0 +/- 0.63) to achieve a diameter of 15 mm dilatation, with uniformly good response over a mean follow-up period of 14.04 +/- 9.79 months. Corrosive-induced GOO required a larger number of dilatation sessions (2-9, mean 5.63 +/- 2.88), but the response was equally good, with follow up of 12-30 months. Patients with pancreatitis-related GOO, however, failed to respond despite a mean of 5.50 (+/-0.58) dilatations, and continued to have symptoms. All these patients were subjected to surgical bypass. There were no major complications such as perforation. CONCLUSIONS A good response can be expected in the majority of patients with peptic and corrosive-related GOO after balloon dilatation; however, poor results are noted for chronic pancreatitis-related GOO.

Abstract
BACKGROUND Gastric outlet obstruction (GOO) secondary to peptic ulcer disease requiring therapeutic intervention remains a common problem. The incidence of Helicobacter pylori infection in this cohort has not been well defined. Pneumatic dilatation (PD) has been proposed as first-line therapy before surgical intervention. If H pylori infection in patients with GOO is infrequent, PD may not offer permanent control without the need for longterm antacid therapy. STUDY DESIGN The purpose of this study was to examine the incidence of H pylori infection and surgical outcomes in patients undergoing resection for GOO. The records of all patients having resection (vagotomy and antrectomy) for benign disease from 1993 to 1998 for GOO at the University of Tennessee affiliated hospitals were reviewed retrospectively. Smoking history, NSAID use, weight loss, previous ulcer treatment, previous treatment for H pylori, and previous attempts at PD were among the factors examined. H pylori infection was documented by Steiner stain from either preoperative biopsy or, in most patients, final surgical specimens. Surgical complications and patient satisfaction were ascertained from inpatient records, postoperative clinical notes, and, where possible, followup telephone surveys. RESULTS Twenty-four patients underwent surgical resection during the study period. There were 16 men and 8 women, with a mean age of 61 years (range 40 to 87 years). Weight loss was documented in 58% and averaged 27 lb. Five of 24 patients had previous attempts at PD, 3 of whom were H pylori negative. All five had further weight loss after these failed attempts. Of the 24 patients reviewed, only 8 (33%) were H pylori positive. There were no procedure-related deaths. Longterm clinical followup was possible in 16 of 24 patients, and all but one demonstrated dramatic clinical improvement by Visick score. CONCLUSIONS We conclude the following: 1) In this cohort, H pylori infection was present in a minority; 2) previous attempts at PD were unsuccessful, which may be related to the H pylori-negative status of the patients; 3) mortality related to the operation was zero; and 4) patient satisfaction was positive by the Visick scale. Patients with H pylori-negative GOO resulting from peptic ulcer disease should be strongly considered for an early, definitive, acid-reducing surgical procedure.

Abstract
A through-the-scope endoscopic balloon dilatation technique and acid-reducing medication was used in 46 consecutive patients (median age, 55; range, 21-88 years) with benign gastric outlet obstruction. In five patients, dilatation was not technically possible. In 41 patients, 122 dilatations (median, 2; range, 1-9 per patient) were performed without morbidity. Ninety-four procedures were successful (77%) at the initial attempt (able to pass a 12-mm endoscope into the duodenum at the end of the procedure). Median follow-up in the 41 patients was 19 (range, 1-78) months. Thirteen patients (32%) required subsequent surgery; 8 had delayed operation for persistent symptoms (1-28 months after the first dilatation), 1 had surgery during the initial hospital admission, and 4 required emergency surgery for other ulcer complications (3 perforation, 1 bleeding). Of the 28 patients who had only balloon dilatation and medical therapy, 11 are asymptomatic (4 with active ulceration), 9 have mild symptoms (Visick 2), and 3 have persistent symptoms (Visick 3). One patient was lost to follow-up and four patients have died (one from an ulcer-related complication). Balloon dilatation and sustained acid-reducing therapy with regular endoscopic surveillance should be first-line treatment of peptic pyloroduodenal strictures, because the procedure is safe and is likely to be successful in half of the patients in whom dilatation is technically possible.

Abstract
We report a Helicobacter pylori-related antral gastric ulcer that continued to cause symptoms despite H. pylori eradication. The patient had progressive gastric outlet obstruction, raising the possibility of a malignancy. On exploratory laparotomy, he was found to have a large inflammatory mass surrounding a contained microperforation.

Abstract
Acquired gastric outlet obstruction is more commonly owing to malignancy than ulcer disease. Endoscopy is the preferred method for diagnosis. Surgical palliation for malignant disease has poor results and high rates of morbidity and mortality. Initial experiences with endoscopic palliation with expandable metallic endoprostheses appear promising. Peptic ulcer-induced gastric outlet obstruction can be treated safely with endoscopic balloon dilation. About 65% of patients have sustained symptom relief, but many require more than one dilation session. Outcomes may be improved with effective ulcer therapy with acid reduction and eradication of H. pylori. Surgery is associated with significant morbidity and mortality and should be reserved for endoscopic treatment failures.

Abstract
Peptic ulcer disease (PUD) requiring surgical treatment has become rare with the availability of modern medical management. A retrospective study of all patients who required operations for PUD between 1949 and 1994 (n = 43) was done. The patients were classified into 3 groups: A (n = 38): pre-histamine-2 (H2) blocker era (1949-1975); B (n = 3): pre-hydrogen-potassium (H-K+) ATPase inhibitor era (1976-1988); C (n = 2): H-K+ ATPase inhibitor era (1989-1994). Data, analyzed using X2 analysis (P < .01), included preoperative medical therapy, surgical indications, type of operation performed, complications, and postoperative medical therapy. The indication for surgery in group A was bleeding (26), perforation (8), or obstruction (4); in group B the indication was obstruction (2) or perforation (1); in group C the indication was obstruction (1) or bleeding (1). The incidence of obstruction as an indication for surgery did not differ among the groups (P < .01). Two of the three patients who had surgery for obstruction in groups B and C had biopsy-proven Helicobacter pylori. The postoperative morbidity rate was lower for groups B and C, although not significantly. The relative mortality among the groups did not change (P > .01). Children with PUD can have complications similar to those of adults with PUD. Since the introduction of H2 antagonists, the recognition and treatment of H pylori, and the use of H-K+ ATPase inhibition, the incidence of operations for bleeding and perforation has decreased dramatically. However, the incidence of surgery for obstruction remains the same.

Abstract
BACKGROUND Gastric outlet obstruction secondary to chronic duodenal ulceration is an indication for surgery as conservative management with balloon dilatation frequently fails. The standard operation is truncal vagotomy and a drainage procedure. However, development of minimally invasive surgery has revolutionized the surgical approach to this clinical problem. METHODS Twelve male patients with pyloric stenosis secondary to duodenal ulceration underwent laparoscopic truncal vagotomy and gastrojejunostomy. The perioperative and long term outcome of this group of patients were analyzed. RESULTS The median operating time was 210 (range 180 to 240) minutes. Median postoperative stay was 6 (range 4 to 41) days. Conversion to laparotomy was necessary in one patient. Delayed gastric emptying occurred in two patients but resolved on conservative measures. At a median postoperative followup of 6 (range 1 to 12) months all patients had a good symptomatic outcome (Visick grades I or II). CONCLUSIONS Laparoscopic truncal vagotomy and gastrojejunostomy is a feasible technique. Intermediate followup shows good symptomatic results when used for pyloric stenosis.

Abstract
BACKGROUND Through-the-scope balloon dilation has been used for treatment of benign pyloric stenosis; however, long-term results are lacking in the literature. METHOD A retrospective analysis using the Kaplan-Meier method. RESULTS Between November 1986 and December 1993, 54 patients underwent through-the-scope balloon dilations for pyloric stenosis. The mean age was 57.5 years. There were 5 (9.3%) initial treatment failures due to tight stenoses and perforations from dilation occurred in 4(7.4%) patients. Forty-five (83.3%) patients underwent successful dilation. Four patients developed rapid restenoses and were found to have malignant obstructions. Forty-one patients entered our study. Time at risk commenced on the date of initial dilation. The end point was defined at the time at which patients presented with recurrent obstruction or other ulcer complications. The median follow-up period was 39 months. The ulcer complication-free probability at 3 months, and at 1, 2, and 3 years was 79.1%, 73.4%, 69.3%, and 54.7%, respectively. In all, 21 (51.2%) patients required subsequent surgery: 18 for recurrent obstructions, 2 for interval perforations, and 1 for bleeding. CONCLUSION While through-the-scope balloon dilation may palliate symptoms of obstruction, recurrent obstruction and other ulcer complications are common. It should be reserved only for patients at high risk for operative surgery.

Abstract
Although the immediate success of endoscopic balloon dilation of nonmalignant and noncongenital pyloric stenosis is known, little information is available on the long-term results of such therapy. Of 19 patients who underwent this treatment at our institution for gastric outlet obstruction, 3 (16%) experienced sustained relief and 16 (84%) had a recurrence of symptoms during a median follow-up period of 45 months. Twelve of the patients who had a recurrence of gastric outlet obstructive symptoms required further therapy. Our results suggest that if followed for a prolonged period of time, patients who have undergone endoscopic balloon dilation of nonmalignant pyloric stenosis have a high recurrence rate of symptomatic gastric outlet obstruction.

Abstract
Balloon dilation of gastrointestinal strictures using a radiologic, endoscopic or combined approach is a safe, effective means of managing an ever-increasing variety of stricturing processes. At present the ability to dilate strictures in the gastrointestinal tract is limited mainly by access. Balloon dilation is now well established in the management of oesophageal and anastomotic lesions. The place of balloon dilation in the management of Crohn's disease and in the management of malignant disease requires further evaluation.

Abstract
The diagnosis and treatment of acute bleeding caused by peptic ulcer disease has been greatly facilitated by fiberoptic endoscopy. The basic differentiation between malignant and benign gastric ulcer requires endoscopic confirmation with biopsy. The management of bleeding from peptic ulceration can be enhanced by endoscopic examination as can the prediction of risk for recurrent bleeding or need for surgical intervention. Various therapeutic maneuvers can be performed endoscopically, including monopolar and multipolar cautery, laser and heater probe therapy, and injection of vasoconstrictors to control bleeding. Endoscopic balloon dilation for the management of gastric outlet obstruction is often effective.

Abstract
Therapeutic procedures in upper gastrointestinal endoscopy are usually performed with the patient under sedation, and there is a clear advantage with video endoscopy. The endoscopy assistant needs full training on the appropriate and safe use of equipment and accessories. Complications of procedures should be detected early and managed appropriately. Indications, results, and perspectives of endoscopic procedures are reviewed for the following situations: gastrointestinal bleeding, caustic injury, foreign bodies, advanced and superficial cancer, dysplasia, reflux esophagitis, motility disorders, and nutritional assistance. Consolidation of current methods and systematic evaluation of the results of therapeutic endoscopy are important tasks for the near future.
