This is a successful removal of more than 450 pieces of metal objects from a patient's stomach: a case report.

BACKGROUND: Ingestion of foreign bodies may be seen unconsciously or intentionally in patients with mental health problems. Most cases pass through the esophagus slowly; however, in some cases, the tumor may be located in narrower areas of the digestive tract that require endoscopic or surgical intervention. This study describes a rare case of successful removal of more than 450 pieces of metal objects from the stomach of a 36-year-old man via ingestion of foreign bodies at Imam Khomeini Hospital in Ahvaz. CASE PRESENTATION: A 36-year-old male patient (Aryan race) presented with complaints of chronic abdominal pain, frequent vomiting, and intolerance to liquids and food. The patient's companions mentioned a history of gradual ingestion of small metal objects 3 months prior. The patient was conscious and had stable vital signs. In the patient's X-ray and endoscopy, multiple metal objects inside the patient's stomach were observed, causing gastric outlet obstruction. The patient underwent gastrostomy surgery, and 452 screws, nuts, keys, stones, and other metal parts weighing 2900 g were removed from the stomach. Five days after the operation, the patient was transferred to the psychiatric service in good general condition and was diagnosed with psychosis, and her condition returned to normal at follow-up. CONCLUSION: Successful removal of this foreign body is rare. In chronic abdominal pain, especially in the context of psychiatric disorders, attention should be given to the ingestion of foreign bodies. In swallowing large amounts of sharp and metallic foreign objects, surgical intervention is necessary, especially in cases of obstruction, and saves the patient's life.

A Classification for Gastric Outlet Obstruction in Childhood: Extending Beyond Infantile Hypertrophic Pyloric Stenosis.

BACKGROUND/AIMS:  Gastric outlet obstruction (GOO) is a rare condition in childhood, with the exception of infantile hypertrophic pyloric stenosis (IHPS). However, no classification exists from a pediatric gastroenterologist's perspective. MATERIALS AND METHODS:  The patients with a diagnosis of GOO between 2009 and 2020 were reviewed retrospectively. We classified the patients according to GOO: presence of clinical findings accompanied by radiological and/or endoscopic findings; clinical status: intractable nonbilious postprandial vomiting alone or with abdominal pain, early satiety, weight loss, postprandial abdominal distension, and malnutrition; radiology: delayed gastric emptying and dilated stomach; endoscopy: nonbilious gastric contents after 6-8 hours of emptying and/or failed pyloric intubation; physical examination: visible gastric peristalsis. RESULTS:  A total of 30 GOO patients (15 patients with IHPS, 1 patient with annular pancreas, 4 patients with gastric volvulus, 2 patients with duodenal atresia, 2 patients with antral web, 1 patient with late-onset hypertrophic pyloric stenosis (LHPS) had surgical treatment, and remaining 5 patients had medical treatment) were enrolled to the study. The median age was 8 months (range: 3 months-16 years), and 14 patients were female. Mitochondrial disorders, LHPS, metabolic disorders, and eosinophilic gastrointestinal system diseases were added to Sharma's GOO classification, and the classification has been expanded. CONCLUSION:  This is the first and largest study of GOO in children. From the perspective of pediatric gastroenterology, new diseases will be addressed, and definitions will be highlighted with our classification for GOO in childhood.

[Upper gastro-intestinal tumour stenosis treated by a new endoscopic approach]. / Sténose digestive tumorale haute traitée par une nouvelle approche endoscopique.

Gastric outlet obstruction (GOO) is a mechanical obstruction of the distal stomach or proximal duodenum. Surgical gastro-jejunostomy and self-expanding metal duodenal stents were the conventional treatments for GOO. In recent years, a new treatment option emerged using echo-guided endoscopic gastroenterostomy (EUS-GE). It appears to be a safe and effective technique with a clinical success rate of 85-90 % and a side effect rate of less than 18 %. Compared to metal duodenal prostheses, the risk of recurrence of GOO and of re-intervention is lower with EUS-GE. The rate of side effects also appears to be lower than with the surgical technique, with a shorter length of hospital stay. Randomised studies comparing these different techniques are still needed to determine a new treatment algorithm for GOO. We report a case of successful EUS-GE performed at our institution.

La «gastric outlet obstruction¼ (GOO) est une obstruction mécanique de l'estomac distal ou du duodénum proximal. La gastro-jéjunostomie chirurgicale et les endoprothèses métalliques auto-expansibles duodénales étaient les traitements conventionnels de la GOO. Ces dernières années, une nouvelle option thérapeutique est apparue utilisant la gastro-entéro-anastomose par voie endoscopique écho-guidée (GE-EEG). Elle semble être une technique sûre et efficace avec un taux de succès clinique de 85 à 90 % et un taux d'effets secondaires de moins de 18 %. Comparé aux prothèses duodénales métalliques, le risque de récidive de la GOO et de réintervention est plus faible avec la GE-EEG. Le taux de manifestations indésirables semble également être plus faible qu'avec la technique chirurgicale, avec une durée de séjour hospitalier plus courte. Des études randomisées comparant ces différentes techniques sont encore nécessaires pour déterminer un nouvel algorithme de traitement pour la GOO. Nous rapportons un cas de GE-EEG réalisée avec succès dans notre institution.

[Treatment Strategies for Gastric Cancer Patients with Gastric Outlet Obstruction].

Gastric cancer frequently leads to gastric outlet obstruction (GOO), causing significant symptoms and complications. Surgical bypass and stenting are two representative palliative treatments for GOO by gastric cancer. This study reviews clinical guidelines for malignant GOO treatment, highlighting differences in recommendations based on patient survival expectations and systemic health. A meta-analysis of surgical bypass and stenting in gastric cancer patients revealed no significant difference in technical and clinical success rates between the two treatments. However, stenting allowed faster resumption of oral intake and shorter hospital stays but had higher rates of major complications and reobstruction. Despite these differences, overall survival did not significantly differ between the two groups. Emerging techniques like EUS-guided gastrojejunostomy show promise but require further research and experienced practitioners. Ultimately, treatment should be tailored to patient preferences and the specific benefits and drawbacks of each method to improve quality of life and outcomes.

Congenital pyloric atresia associated with epidermolysis bullosa junctionalis: a novel lethal variant.

A term male baby was born vaginally to a primi mother. An antenatal ultrasound revealed polyhydramnios and a distended stomach in the baby. At birth, the baby had well-defined areas of peeling skin on the face and blisters on the forearm region. The abdominal X-ray revealed a single gastric bubble, which is consistent with pyloric atresia and needs surgery. Pyloroplasty was initially performed, but it was unsuccessful. Therefore, a feeding jejunostomy and gastrostomy were performed. However, the baby developed sepsis and septic shock and died at about 2 months of age. Skin biopsy revealed cleavage above the lamina densa, and genetic analysis indicated heterozygosity in ITGB4 exons 10 and 16, which are associated with epidermolysis bullosa junctionalis and pyloric atresia.

Surgical versus endoscopic gastroenterostomy for gastric outlet obstruction: a retrospective multicentric comparative study of technical and clinical success.

PURPOSE: Gastric outlet obstruction (GOO) is mainly due to advanced malignant disease. GOO can be treated by surgical gastroenterostomy (SGE), endoscopic enteral stenting (EES), or endoscopic ultrasound-guided gastroenterostomy (EUS-GE) to improve the quality of life. METHODS: Between 2009 and 2022, patients undergoing SGE or EUS-GE for GOO were included at three centers. Technical and clinical success rates, post-procedure adverse events (AEs), length of hospital stay (LOS), 30-day all-cause mortality, and recurrence of GOO were retrospectively analyzed and compared between SGE and EUS-GE. Predictive factors for technical and clinical failure after SGE and EUS-GE were identified. RESULTS: Of the 97 patients included, 56 (57.7%) had an EUS-GE and 41 (42.3%) had an SGE for GOO, with 62 (63.9%) GOO due to malignancy and 35 (36.1%) to benign disease. The median follow-up time was 13,4 months (range 1 days-106 months), with no difference between the two groups (p = 0.962). Technical (p = 0.133) and clinical (p = 0.229) success rates, severe morbidity (p = 0.708), 30-day all-cause mortality (p = 0.277) and GOO recurrence (p = 1) were similar. EUS-GE had shorter median procedure duration (p < 0.001), lower post-procedure ileus rate (p < 0.001), and shorter median LOS (p < 0.001) than SGE. In univariate analysis, no risk factors for technical or clinical failure in SGE were identified and abdominal pain reported before the procedure was a risk factor for technical failure in the EUS-GE group. No risk factor for clinical failure was identified for EUS-GE. In the subgroup of GOO due to benign disease, SGE was associated with better technical success (p = 0.035) with no difference in clinical success rate compared to EUS-GE (p = 1). CONCLUSION: EUS-GE provides similar long-lasting symptom relief as SGE for GOO whether for benign or malignant disease. SGE may still be indicated in centers with limited experience with EUS-GE or may be reserved for patients in whom endoscopic technique fails.

Management of complicated Bouveret's syndrome.

Bouveret's syndrome is an uncommon cause of gastric outlet obstruction caused by the impaction of large gallstones in the duodenal lumen. The gallstones pass into the duodenal lumen through a cholecystogastric or a cholecystoduodenal fistula. Endoscopic retrieval with or without lithotripsy is the first line of management, often with variable success. We present a case of a woman in her 70s who presented with signs of gastric outlet obstruction and was diagnosed with Bouveret's syndrome with a 5 cm diameter gallstone in the third part of her duodenum. Following several unsuccessful attempts of endoscopic extraction, she underwent successful jejunal enterotomy with fragmentation and extraction of the calculus using an Allis tissue holding forceps. Postoperative recovery was uneventful.

Endoscopic ultrasound-guided gastrojejunostomy for benign gastric outlet obstruction (GOO): a retrospective analysis of patients and outcomes.

BACKGROUND AND STUDY AIMS: Endoscopic ultrasound-guided gastrojejunostomy (EUS-GJ) has been well utilized in treating malignant gastric outlet obstructions (GOO) given its efficacy and lower risk profile compared to surgery. However, its efficacy and potential for use in patients with benign GOO who are poor surgical candidates is not well documented. The aim of this study was to examine the role of EUS-GJ in treatment of benign GOO in select patients. PATIENTS AND METHODS: This is a single-center, open-label, retrospective descriptive study that included all consecutive patients undergoing EUS-GJ to treat benign causes of GOO. Direct antegrade and direct retrograde methods were utilized. RESULTS: A total of 18 patients were included, 38.9% female with an average age of 63.3 years. Extrinsic GOO was present in (10 of 18) 55.5% of patients and intrinsic etiology was present in (8 of 18) 45.5% of patients. Technical success was achieved in 100% (18 of 18) patients and clinical success was achieved in 94% (17 of 18) patients. In total, 13 patients had follow-up endoscopy, 2 patients were treated relatively recently in time, 1 patient was lost to follow-up, and 2 patients died of other chronic illnesses. Stents remained in place for a median of 286 days (range 88-1444 days). In patients whose stents were removed, 75% (3 of 4) had extrinsic etiologies of GOO. CONCLUSIONS: This study reports a favorable long-term patency with excellent technical and clinical success of EUS-GJ in patients with benign GOO. Despite the limitations of sample size and retrospective nature, it adds to the extremely limited literature of EUS-GJ in management of patients with benign GOO.

Systematic review of long-term effectiveness of endoscopic gastrojejunostomy in patients presenting with gastric outlet obstruction from periampullary malignancies.

BACKGROUND: Recently, endoscopic ultrasound-guided (EUS) gastrojejunostomy (GJ) has emerged as an alternative option to surgical palliation and endoscopic duodenal stenting for malignant gastric outlet obstruction (GOO). Although early success rates are commonly reported with the technique, there is a paucity of data regarding the long-term efficacy of this approach. In this study, we investigated long-term outcomes in patients that underwent EUS-guided GJ for palliation of periampullary malignancies. METHODS: From a total of 192 studies that were reviewed, 6 studies with a follow-up time frame of a minimum of 5 months were analyzed, totaling 238 patients. Outcome variables included technical success rate, clinical success rate, adverse events, symptom recurrence, and re-intervention rates. RESULTS: The cohort of 238 patients had a technical success rate of 93.7% and a clinical success rate of 92.9%. A total of 25 patients (10.5%) experienced adverse events associated with EUS-GJ. A total of 14 patients (5.9%) experienced recurrence of GOO symptoms within 5 months. A total of 14 patients (5.9%) underwent re-intervention with the first 5 months. CONCLUSIONS: This systematic review shows that data are scarce regarding long-term effectiveness of EUS-guided GJ. Even though early success rates have been reported, further studies are needed to focus on long-term efficacy of this approach. Until such studies become available, surgical palliation should continue to be the treatment of choice for patients with malignant GOO with a prolonged life expectancy.

Bouveret Syndrome: A Curious Simultaneous Presentation of Two Cases: Comparison of Clinical Observations and Surgical Management.

Gallstone ileus is an uncommon occurrence and accounts for about 0.3-0.5% of complications of cholelithiasis in elderly patients. Bouveret syndrome is an uncommon medical condition resulting from the blockage of the duodenal bulb by a stone, which consequently obstructs the outlet of the stomach. Until now, a comparison of two different presentations of Bouveret syndrome has not been published in the literature due to the rarity of this pathology. The curious simultaneous occurrence of the two cases discussed here made it possible for us to compare the different diagnostic and therapeutic pathways. In fact, both cases differ not only in their presenting symptoms, but also in the management adopted by the same surgical team.

Unusual case of Niemeier type II gallbladder perforation: case report and literature review.

Niemeier type II gallbladder perforation (GBP) is caused by inflammation and necrosis of the gallbladder wall followed by bile spilling into the abdominal cavity after perforation. The gallbladder then becomes adhered to the surrounding inflammatory tissue to form a purulent envelope, which communicates with the gallbladder. At present, the clinical characteristics and treatment of type II GBP are not well understood and management of GBP remains controversial. Type II GBP with gastric outlet obstruction is rare and prone to misdiagnosis and delayed treatment. Recent systematic reviews report that percutaneous drainage does not influence outcomes. In this current case, due to the high risk of bleeding and accidental injury, as well as a lack of access to safely visualize the Calot's triangle, the patient could not undergo laparoscopic cholecystectomy, which would have been the ideal option. This current case report presents the use of percutaneous laparoscopic drainage combined with percutaneous transhepatic gallbladder drainage in a patient with type II GBP associated with gastric outlet obstruction. A review of the relevant literature has been provided in addition to a summary of the clinical manifestations and treatments for type II GBP.

Alarming Incidence of Gastric Outlet Obstruction Related to NSAIDS and Synthetic Opioid in North West India.

BACKGROUND: In recent years, there has been an alarming increase in cases of gastric outlet obstruction (GOO) at our center due to drug abuse. So, we conducted this study to know the incidence of nonsteroidal anti-inflammatory drugs (NSAIDs) and synthetic opioid abuse in cases of GOO. METHODS: This was an observational study involving consecutive cases of GOO diagnosed from September 2017 to February 2019. A detailed history, including drug addiction history and clinical examination, was done. Investigations included routine biochemical and hematological tests, upper gastrointestinal endoscopy (UGIE), ultrasonography, rapid urease test (RUT), and histopathology of the diseased area. RESULTS: Among the 102 cases diagnosed with GOO, 62 (60.78%) cases had a history of drug addiction. The drug addiction history was as follows: NSAIDs and opioids in 56, opioids alone in four, and NSAIDs alone in two cases. The most common site of stricture was the second part of the duodenum. The features on histopathology were ulcerations of the mucosa infiltrated by eosinophils, plasma cells, and lymphocytes. CONCLUSION: There is an alarming increase in the incidence of GOO due to NSAIDs and opioid abuse at our center. Efforts should be made to control the indiscriminate use of these over-the-counter drugs to prevent dreaded complications.

Management of Malignant Gastric Outlet Obstruction: A Comprehensive Review on the Old, the Classic and the Innovative Approaches.

Gastrojejunostomy is the principal method of palliation for unresectable malignant gastric outlet obstructions (GOO). Gastrojejunostomy was traditionally performed as a surgical procedure with an open approach butrecently, notable progress in the development of minimally invasive procedures such as laparoscopic gastrojejunostomies have emerged. Additionally, advancements in endoscopic techniques, including endoscopic stenting (ES) and endoscopic ultrasound-guided gastroenterostomy (EUS-GE), are becoming more prominent. ES involves the placement of self-expandable metal stents (SEMS) to restore luminal patency. ES is commonly the first choice for patients deemed unfit for surgery or at high surgical risk. However, although ES leads to rapid improvement of symptoms, it carries limitations like higher stent dysfunction rates and the need for frequent re-interventions. Recently, EUS-GE has emerged as a potential alternative, combining the minimally invasive nature of the endoscopic approach with the long-lasting effects of a gastrojejunostomy. Having reviewed the advantages and disadvantages of these different techniques, this article aims to provide a comprehensive review regarding the management of unresectable malignant GOO.

Management of malignant Gastric Outlet Obstruction (mGOO) due to pancreatic cancer in the era of EUS-Gastrojejunostomy: an international practice survey and case vignette study by Pancreas 2000 from the European Pancreatic Club.

BACKGROUND: Malignant Gastric Outlet Obstruction (mGOO) has been standardly treated by surgical Gastrojejunostomy (S-GJ) or Endoscopic Stenting (ES). Recently, EUS-Gastrojejunostomy (EUS-GJ) has emerged as an alternative, despite its worldwide diffusion is heterogeneous. The aim of this survey was to assess clinical decision-making around mGOO and to explore current opinions regarding EUS-GJ. METHODS: An online survey, spread through social networks and EPC newsletter, was created exploring opinions regarding indications, contraindications, benefits/risks, availability of mGOO treatments; 2 case vignettes explored clinical decision-making in different scenarios. RESULTS: Overall, 290 pancreatologists from 44 countries responded, of whom 35% surgeons and 65% gastroenterologists. The most common treatment for mGOO was ES (86%), followed by laparoscopic GJ (76%). EUS-GJ was accessible to 59% of respondents, with 10% proficient in this technique. Gold-standard treatment for mGOO varied by specialty; 45% of gastroenterologists preferred ES, 20% EUS-GJ, and 10% surgical GJ, while among surgeons, these were 24%, 8%, and 25%, respectively. A higher annual volume of mGOO treated correlated with increased EUS-GJ adoption and reduced surgical advice. For 51%, EUS-GJ will become the primary treatment for mGOO, notably higher among gastroenterologists and high-volume centers. For 14%, EUS-GJ spread will be limited in the future, or used only when ES fails (19%). Life expectancy, disease stage and patient's frailty are the main decision driver in therapeutic choice, whereas future surgical resectability does not contraindicate any treatment for 75%. EUS-GJ's main advantages were its minimally invasive nature and clinical efficacy, offset by its steep learning curve. CONCLUSIONS: This survey revealed significant differences in the management of mGOO, depending on specialties, local expertise and treatment volume, suggesting the lack of standardized algorithms. Life expectancy and patients' frailty are the main decision drivers. Regarding EUS-GJ, its availability remains suboptimal, with learning curve as the main perceived barrier.

Propensity score-matched retrospective cohort study of endoscopic ultrasound-guided gastroenterostomy and enteral stenting for malignant gastric outlet.

BACKGROUND: Symptomatic malignant gastric outlet obstruction (GOO) significantly reduce patients' quality of life. Endoscopic treatment involves enteral stenting or endoscopic ultrasonography to perform gastroenterostomy (EUS-GE). Aim was to compare enteral stenting with EUS-GE for endoscopic treatment of malignant GOO. METHODS: We retrospectively compared enteral stenting with EUS-GE for the treatment of malignant GOO. Patients treated at our institution were identified and a propensity score matching analysis was performed. Treatment failure was the primary outcome, while the secondary endpoints were time until treatment failure, technical and clinical success rates, and adverse event rates. RESULTS: Eighty-eight patients were included in the final analysis. Of whom, 44 were included in each of the two treatment groups. Treatment failure occurred significantly more frequently in the enteral stenting group (13/44) compared with the EUS-GE group (4/44; hazard ratio: 4,9; 95% CI 1.6-15.1). A Kaplan-Meier analysis revealed a median time until treatment failure of 22.0 weeks (95% CI 4.6-39.4) in the enteral stenting group compared with 76.0 weeks (95% CI 55.9-96.1) in the EUS-GE group (P = .002). No difference in technical success and clinical success was detected. Technical success was achieved in 43/44 patients (97.7%) in the enteral stenting group compared with 41/44 patients (93.2%) in the EUS-GE group, while clinical success was achieved in 32/44 (72.7%) and 35/44 (79.5%) patients, respectively. Nine adverse events were observed (9/44, 10.2%). There were no differences in 30-day adverse event rate and 30-day mortality rate. CONCLUSION: EUS-GE was superior to enteral stenting in the treatment of malignant GOO in terms of treatment failure and time until treatment failure in a propensity score-matched cohort.
