Acute idiopathic mesenteroaxial gastric volvulus managed laparoscopically.

Gastric volvulus is an uncommon cause of upper gastrointestinal obstruction that occurs when the stomach twists along its vertical (organoaxial) or horizontal (mesenteroaxial) axis. Its rarity combined with its non-specific presentation makes gastric volvulus a diagnostic challenge, especially when the volvulus occurs without underlying structural abnormality such as hiatal hernia. The organoaxial type comprises most cases of this rare diagnosis. Few cases of mesenteroaxial volvulus have been reported in children and even fewer in adults. Here, we present a rare case of acute, idiopathic mesenteroaxial volvulus in a patient in his 70s, that was successfully managed laparoscopically.

Acute gastric volvulus secondary to H-type tracheo-oesophageal fistula.

H-type tracheo-oesophageal fistula is an uncommon type of tracheo-oesophageal malformation. Acute gastric volvulus is another infrequent pathology in children. They rarely present together.We report the case of a toddler with acute gastric volvulus possibly secondary to an undiagnosed H-type tracheo-oesophageal fistula. The fistula was suspected due to persistent gastric distention observed during volvulus detorsion. This kind of tracheo-oesophageal fistula often presents with subtle symptoms making early diagnosis difficult.Acute gastric volvulus is a life-threatening condition. Gastric distension caused by the passage of air into the stomach through the fistula could be a triggering factor for gastric volvulus.

An acute gastric volvulus in a child with congenital left diaphragmatic hernia: a case report.

BACKGROUND: Acute complete gastric volvulus is a rare and life-threatening disease, which is prone to gastric wall ischemia, perforation, and necrosis. If it is not treated by surgery in time, the mortality rate can range from 30 to 50%. Clinical presentations of acute gastric volvulus are atypical and often mimic other abdominal conditions such as gastritis, gastroesophageal reflux, gastric dilation, and pancreatitis. Imaging studies are crucial for diagnosis, with barium meal fluoroscopy being the primary modality for diagnosing gastric volvulus. Cases of acute gastric volvulus diagnosed by ultrasound are rarely reported. CASE PRESENTATION: We reported a rare case of acute gastric volvulus in a 4-year-old Chinese girl who presented with vomiting and abdominal pain. Ultrasound examination revealed the "whirlpool sign" in the cardia region, raising suspicion of gastric volvulus. Diagnosis was confirmed by X-ray barium meal fluoroscopy, which indicated left-sided diaphragmatic hernia and obstruction at the cardia region. Surgical intervention confirmed our suspicion of acute complete gastric volvulus combined with diaphragmatic hernia. CONCLUSION: In this case, we reported an instance of acute complete gastric volvulus. Ultrasound revealed a "whirlpool sign" in the cardia, which is likely to be a key sign for the diagnosis of complete gastric volvulus.

Self-reducing intrathoracic organo-axial gastric volvulus with paraoesophageal hiatus hernia in a toddler.

A toddler presented with complaints of multiple episodes of vomiting lasting 1 week. He had a history of similar episodes of vomiting several times as an infant. Clinically, he was underweight and had tachypnoea and tachycardia. Laboratory investigations revealed hyponatraemic metabolic acidosis. His chest radiograph revealed an intrathoracic herniation of the stomach with an atypical presence towards the right hemithorax, suggestive of a torsion. A contrast-enhanced CT of the chest and abdomen confirmed an intrathoracic gastric herniation, with an organo-axial gastric volvulus, with no features of strangulation. He underwent an emergency laparotomy and intraoperatively the stomach was found to have reduced to its intra-abdominal position, and the hernia and volvulus had also self-reduced. In view of the multiple symptomatic episodes, an anterior gastropexy was performed to prevent recurrences. The patient recuperated well and has not had any recurrences in the follow-up period. This report adds to the minimalistic literature.

The Evaluation of Gastric Emptying Using the 13 C-Acetate Breath Test in Neurologically Impaired Patients - A Focus on the Stomach Function and Morphology.

PURPOSE: We explored factors affecting gastric emptying in neurologically impaired (NI) patients using the 13C-acetate breath test. METHODS: Twenty-four NI patients were classified by the presence of gastroesophageal reflux disease (GERD), which was treated by fundoplication plus gastrostomy, or the absence of GERD, which was treated by gastrostomy alone, along with gastric malposition involving cascade stomach and organoaxial gastric volvulus (OGV). Gastric emptying parameters (GEPs), which were the emptying half time (T 1/2 , minute), the lag phase time (T lag , minute), and the gastric emptying coefficient (GEC), were measured before and after surgery. We evaluated the relationship between GEPs and GERD, gastric malposition, and surgical intervention. All data were expressed as the median (interquartile range). RESULTS: The T1/2 and GEC of patients with OGV were significantly worse than in those without OGV before surgery (T1/2 with OGV: 241.3 [154.9, 314.3] vs. T1/2 without OGV: 113.7 [105.2, 151.4], p = 0.01, GEC with OGV: 3.19 [2.46, 3.28] vs. GEC without OGV: 3.65 [3.24, 3.90], p = 0.02). GERD and cascade stomach were not associ ated with GEPs. The GEPs of all NI patients showed no significant difference between before and after surgery. The surgical change in T1/2 (ΔT 1/2 ) in the patients with OGV was significantly lower than in those without OGV (ΔT1/2 with OGV: -47.1 [-142.7, -22.1] vs. ΔT1/2 without OGV: -3.78 [-26.6, 12.0], p = 0.03). CONCLUSION: Stomach malposition, such as OGV, seems to affect gastric emptying and may be improved by surgi cal intervention.

BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT.

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

Bilious abdomen development in a dog following prophylactic incisional gastropexy and a hollow viscus distension event.

Bilious abdomen is an uncommon but life-threatening condition that has not previously been associated with prophylactic gastropexy. In animals, bilious abdomen is associated with a high mortality rate, due in large part to resulting bile peritonitis. Most bilious abdomen cases in veterinary medicine occur secondary to underlying gallbladder disease or blunt abdominal trauma. This case report describes an instance of atraumatic bilious abdomen with no evidence of primary hepatobiliary disease. Prophylactic incisional gastropexy was performed on a dog within 72 h of its developing bilious abdomen. It is possible that undergoing a gastropexy increased tension on the common bile duct, but no known direct surgical trauma to the duct occurred. The cause of bile leakage in this case is suspected to be secondary to trauma from a distended hollow viscus. Findings at the time of the second surgery support this conclusion. Key clinical message: This case suggests a novel mechanism for the development of bilious abdomen in dogs.

Développement d'un abdomen bilieux chez un chien après une gastropexie incisionnelle prophylactique et un événement de distension des viscères creux. L'abdomen bilieux est une affection rare mais potentiellement mortelle qui n'a jamais été associée à une gastropexie prophylactique. Chez les animaux, l'abdomen bilieux est associé à un taux de mortalité élevé, dû en grande partie à la péritonite biliaire qui en résulte. La plupart des cas d'abdomen bilieux en médecine vétérinaire sont secondaires à une maladie sous-jacente de la vésicule biliaire ou à un traumatisme contondant abdominal. Ce rapport de cas décrit un cas d'abdomen bilieux atraumatique sans signe de maladie hépatobiliaire primaire. Une gastropexie incisionnelle prophylactique a été réalisée sur un chien dans les 72 heures précédant le développement de son abdomen bilieux. Il est possible que la gastropexie ait augmenté la tension sur le canal biliaire principal, mais aucun traumatisme chirurgical direct connu du canal ne s'est produit. La cause de la fuite biliaire dans ce cas est soupçonnée d'être secondaire à un traumatisme causé par un viscère creux distendu. Les résultats de la deuxième intervention chirurgicale confortent cette conclusion.Message clinique clé :Ce cas suggère un nouveau mécanisme pour le développement de l'abdomen bilieux chez le chien.(Traduit par Dr Serge Messier).

Use of real-time near-infrared fluorescence to assess gastric viability in dogs with gastric dilatation volvulus: A case-control study.

OBJECTIVE: To describe near-infrared fluorescence (NIRF) for assessment of gastric viability and describe NIRF's influence on the surgeon's operative strategy in dogs with gastric dilatation and volvulus (GDV). STUDY DESIGN: Prospective clinical trial. ANIMALS: Twenty dogs with GDV and 20 systemically healthy dogs. METHODS: Following gastric derotation, the surgeon's subjective assessment of gastric viability was recorded prior to near-infrared imaging. Changes in the surgeon's initial assessment of viability based on the visual pattern of gastric fluorescence was recorded. If nonviable (lack of defined vessels), a partial gastrectomy was performed and submitted for histopathology. The stapled gastrectomy line was imaged. Viable (defined vessels) and nonviable fluorescence intensities were compared with healthy dogs undergoing surgery for nongastrointestinal disease. RESULTS: Subjective assessment diagnosed 17 viable and three nonviable GDVs (2 fundi; 1 cardia). Near-infrared imaging demonstrated nonviable gastric fluorescence in 4 dogs (3 fundi/cardia; 1 fundus). The surgeon's margins for resection were altered in 3/20 dogs. Fluorescence intensity (cardia, fundus, body, pylorus) was lower in GDV viable (30.59%, p = .04; 38.17%, p < .01; 51.18%, p < .01; 44.12%, p= .01) and nonviable (11.00%, p < .01; 4.33%, p < .01; 57.67%, p = .22; 54.33%, p = .72) dogs compared to healthy controls (44.7%, 70.05%, 84.00%, 63.95%). Fundic fluorescence was less in nonviable gastric tissue in comparison with viable gastric tissue (p = .03). Fluorescence of the gastrectomy staple line approximated that of viable tissue. CONCLUSION: Near-infrared fluorescence can identify histologically confirmed nonviable gastric tissue. CLINICAL SIGNIFICANCE: These results provide enough evidence to support the implementation of NIRF as an adjunct to gross examination of the gastric wall in dogs with GDV.

Acute Mesentero-Axial Gastric Volvulus in the Setting of a Paraesophageal Hernia: A Rare Case Report.

Acute gastric volvulus is a surgical emergency that requires urgent intervention to prevent gastric ischemia and necrosis. Gastric volvulus manifests as an abnormal rotation or torsion of the stomach and may be associated with gastric outlet obstruction. This pathology can be classified as either mesentero-axial or organo-axial volvulus, depending on the axis of rotation. Similarly, it can be categorized as primary or secondary, depending on the etiology. We describe a case of a 63-year-old female with a history of peptic ulcer disease who presented with severe epigastric pain and vomiting of one-day duration. She was diagnosed with an acute mesentero-axial gastric volvulus, which was successfully reduced using a nasogastric tube.

Does Fixation of the Gastric Conduit Reduce the Incidence of Gastric Volvulus After Esophagectomy?

BACKGROUND: Acute volvulus of the gastric conduit is a rare complication after esophagectomy that warrants surgical intervention and is associated with increased morbidity and mortality. The aim of the study is to evaluate whether fixation of the gastric conduit would reduce the incidence of postoperative volvulus following esophagectomy. METHODS: This single-center retrospective analysis of patients who underwent esophagectomy was conducted to determine the incidence of acute postoperative volvulus following a change in practice. All patients who underwent an esophagectomy from September 2013 to November 2022 were included. We compared postoperative outcomes of gastric conduit volvulus, reoperations, morbidity, and mortality among those who had fixation versus non-fixation of the conduit to the right pleural edge. RESULTS: Two hundred and forty-two consecutive patients underwent minimally invasive esophagectomy (81% male, 41% were < 67 years old). The first 121 (50%) patients did not undergo fixation of the gastric conduit, while the subsequent 121 (50%) patients did undergo fixation. Comparing both groups, there were no significant differences in major complications, anastomotic leak, and 30-day and 90-day all-cause mortality. Four (2%) patients developed gastric conduit volvulus in the non-fixation group, requiring reoperative intervention. Following implementation of fixation, no patient experienced gastric volvulus. CONCLUSION: Acute volvulus of the gastric conduit is a rare complication after esophagectomy. Early diagnosis and surgical intervention are critical. In this study, although not statistically significant, fixation of the gastric conduit did reduce the number of patients who experienced postoperative volvulus. Additional future studies are needed to validate this technique and the prevention of postoperative acute gastric conduit volvulus among a diverse patient population.

Outcomes and complications of prophylactic incisional gastropexy in 766 dogs (2009-2019).

OBJECTIVE: To report the outcomes and complications associated with prophylactic incisional gastropexy performed in dog breeds at risk for GDV. RESULTS: Seven hundred and sixty-six dogs underwent prophylactic incisional gastropexy of which 61 were electively performed at the time of castration or spay and 705 were adjunctively performed at the time of emergency abdominal surgery. All dogs had short-term follow-up, and 446 dogs (58.2%) had additional follow-up with a median long-term follow-up time of 876 days (range 58-4450). Only 3 dogs (0.4%) had a direct complication associated with the gastropexy site including hemorrhage causing hemoabdomen (2) and infection with partial dehiscence (1). No dogs with long-term follow-up experienced gastric dilatation (GD), gastric dilatation volvulus (GDV), or persistent GI signs following gastropexy. Results of this study found that complications directly associated with prophylactic gastropexy were rare and limited to hemorrhage causing hemoabdomen and infection with partial dehiscence. Transient postoperative GI signs may occur. Gastropexy malpositioning and bowel entrapment were not encountered. There was no occurrence of GD or GDV.

Perioperative characteristics and long-term outcomes following prophylactic total laparoscopic gastropexy using a novel knotless tissue control device in 44 dogs.

Objective: To report on operative technique and outcomes following prophylactic total laparoscopic gastropexy (PTLG) using a novel knotless tissue control device (KTCD) in dogs. Animals: This study included 44 dogs. Procedure: Medical records were reviewed, and perioperative data were collected. Right-sided incisional gastropexy was performed using 2 strands of KTCD introduced through a 12-millimeter cannula in a single-incision multi-channeled port. Dog owners were contacted to obtain outcome data. Results: Median age and weight of dogs were 17 mo (6 to 60 mo) and 48.5 kg (14 to 73.3 kg). Median surgical and anesthesia times were 90 min (60 to 150 min) and 195 min (135 to 270 min). Major intraoperative complications were not reported. Follow-up data were available for 40/44 (91%) dogs. Median follow-up time was 522 d (43 to 983 d). Gastric dilatation volvulus (GDV) was not reported in any dog. One dog developed suspected colonic entrapment around the gastropexy that required surgical revision. All owners were satisfied with the procedure and indicated they would repeat the procedure with future pets. Conclusion: The PTLG procedure using novel KTCD in this cohort of dogs was effective at preventing GDV for the duration of follow-up and was associated with low perioperative complication rate and high owner satisfaction. Clinical relevance: This retrospective study reports on operative technique and outcomes associated with KTCD use in PTLG. Our findings warrant prospective evaluation of KTCD use in PTLG.

Caractéristiques peropératoires et résultats à long terme après une gastropexie laparoscopique totale prophylactique à l'aide d'un nouveau dispositif de contrôle des tissus sans nœuds chez 44 chiens. Objectif: Rendre compte de la technique opératoire et des résultats après une gastropexie laparoscopique totale prophylactique (PTLG) à l'aide d'un nouveau dispositif de contrôle des tissus sans nœuds (KTCD) chez le chien. Animaux: Cette étude a inclus 44 chiens. Procédure: Les dossiers médicaux ont été examinés et les données peropératoires ont été recueillies. La gastropexie incisionnelle du côté droit a été réalisée à l'aide de 2 brins de KTCD introduits par une canule de 12 millimètres dans un orifice multicanal à incision unique. Les propriétaires de chiens ont été contactés pour obtenir des données sur les résultats. Résultats: L'âge et le poids médians des chiens étaient de 17 mois (6 à 60 mois) et 48,5 kg (14 à 73,3 kg). Les temps chirurgicaux et anesthésiques médians étaient de 90 min (60 à 150 min) et 195 min (135 à 270 min). Des complications peropératoires majeures n'ont pas été rapportées. Des données de suivi étaient disponibles pour 40/44 (91 %) chiens. La durée médiane de suivi était de 522 jours (43 à 983 jours). Le volvulus de dilatation gastrique (GDV) n'a été signalé chez aucun chien. Un chien a développé une suspicion de piégeage du côlon autour de la gastropexie qui a nécessité une reprise chirurgicale. Tous les propriétaires étaient satisfaits de la procédure et ont indiqué qu'ils répéteraient la procédure avec de futurs animaux de compagnie. Conclusion: La procédure PTLG utilisant le nouveau KTCD dans cette cohorte de chiens a été efficace pour prévenir le GDV pendant la durée du suivi et a été associée à un faible taux de complications peropératoires et à une satisfaction élevée des propriétaires. Pertinence clinique: Cette étude rétrospective rend compte de la technique opératoire et des résultats associés à l'utilisation de KTCD dans le PTLG. Nos résultats justifient une évaluation prospective de l'utilisation de KTCD dans le PTLG.(Traduit par Dr Serge Messier).

Comparison of incisional gastropexy with and without addition of two full-thickness stomach to body wall sutures.

OBJECTIVE: To compare complications between a modified incisional gastropexy (MIG) technique and standard incisional gastropexy (SIG). ANIMALS: 347 client-owned dogs. PROCEDURES: Dogs that had undergone SIG or MIG from March 2005 through April 2019 were identified through a medical record search of the University of Missouri Veterinary Health Center. The MIG technique is identical to SIG except 2 additional simple interrupted sutures are added, 1 cranial and 1 caudal to the continuous suture line, going full thickness into the stomach to ensure engagement of submucosa. Medical record information was used to identify intraoperative, postoperative, and short-term complications, and telephone or email communication to pet owners and/or referring veterinarians was used to identify complications (short-term and long-term) after discontinuance of care at the University of Missouri Veterinary Health Center. Intraoperative, postoperative, short-term, and long-term complications were analyzed in aggregate within 6 matched groupings: (1) gastropexy for gastric dilatation-volvulus, (2) prophylactic gastropexy without other procedures, (3) gastropexy with ovariohysterectomy, (4) gastropexy with castration, (5) gastropexy with splenectomy, and (6) gastropexy with celiotomy other than splenectomy. Overall rates of complications potentially attributed to gastropexy were compared between SIG and MIG using the Fisher exact test. Overall rates of complications not attributed to gastropexy were compared between SIG and MIG using the χ2 test. RESULTS: There were no significant differences in overall complication rates between SIG and MIG. CLINICAL RELEVANCE: Surgeons who feel that engagement of gastric submucosa is important for gastropexy success may use the MIG technique with minimal fear of complications. However, superiority of one technique over the other cannot be determined on the basis of this study.

Addition of two full-thickness simple interrupted sutures to standard incisional gastropexy increases gastropexy biomechanical strength.

OBJECTIVE: To compare the acute strength (failure load and work to failure) of standard incisional gastropexy (SIG) and modified incisional gastropexy (MIG). ANIMALS: 37 pig cadavers. PROCEDURES: Stomachs and right abdominal walls were harvested from pigs euthanized for reasons unrelated to this study. The tissues were stored in lactated Ringer's solution overnight in a 5 °C cooler. Matching body wall and stomach tissue pairs were randomized and divided into 2 groups, on which either SIG or MIG was performed the following day. The MIG technique was identical to SIG except 2 additional simple interrupted sutures, 1 cranial and 1 caudal to the continuous suture line, were placed full thickness into the stomach to ensure engagement of the submucosa. After gastropexy, the samples underwent biomechanical testing. Information regarding change in position and load was generated by the MTESTQuattro software. Mode of failure was examined after the procedure was complete. RESULTS: The MIG had higher failure load and work to failure compared to SIG. All failures were caused by gastric tissue tearing. CLINICAL RELEVANCE: The MIG is biomechanically superior to SIG and may provide more security than SIG during healing. However, clinical study is needed to ascertain if there is a difference in gastropexy failure and complications between these 2 techniques.

Chronic Intrathoracic Gastric Volvulus Management: Could Less Be More?

Gastric volvulus is a rare medical condition that necessitates a high suspicion index to diagnose. Acute gastric volvulus will often present with nonspecific but severe symptoms of abdominal pain, nausea, vomiting, and in some instances, evidence of organ ischemia. In this case report, we present an 88-year-old woman who was admitted after a mechanical fall. On the third day of hospitalization, she complained of new-onset epigastric pain, nausea, and vomiting. Imaging demonstrated nonobstructed intrathoracic organo-axial gastric volvulus. Given the patient's significant comorbidities, surgical and endoscopic interventions were deemed high-risk (high risk of anesthesia and gastric perforation, respectively). This report evaluates the role of noninterventional conservative management in high-risk surgical patients with symptomatic acute and acute-on-chronic intrathoracic gastric volvulus. The present case and the current literature review suggest that supportive management may be appropriate to control disease symptoms, although it does not alter the disease's natural history, progression, and recurrence.

Congenital diaphragmatic hernia with gastric perforation in adult: Intrathoracic gastric perforation.

Congenital diaphragmatic hernias are rarely seen and they are usually diagnosed in the neonatal period. Congenital diaphragmatic de-fect, also known as Bochdalek hernia, usually occurs with the persistence of the pleuroperitoneal canal in the left posterolateral region of the diaphragm in the embryological period. Although it is rarely seen in the adults, conditions such as intestinal volvulus, strangulation, or perforation with congenital diaphragm defect progress with high mortality and morbidity. In this study, we reported our case that we operated for intrathoracic gastric perforation with congenital diaphragmatic defect. When the patient admitted to the hospital, he had an atypical abdominal pain, significant back pain, and suspicious respiratory complaints. Radiological imaging showed that the stomach and the spleen were located in the left hemithorax due to diaphragmatic hernia also stomach was very dilated. Tachycardia, hypotension, and low saturation developed on the 2nd day of the patient's hospitalization. In the control imaging of the patient, in the left hemithorax, stomach was collapsed and the surrounding appearance compatible with hydropneumothorax, after that findings emergency laparotomy was decided. During the operation, as demonstrated by the radiological findings, a diaphragm defect was seen in the left posterolateral region of the diaphragm. The stomach and spleen were herniated to the left hemithorax from this defect. The stomach and spleen were reduced into the abdomen. The left hemithorax was lavaged with 2000 cc isotonic, left tube thoracostomy was applied, and the diaphragm was repaired. The anterior stomach was primarily repaired. In post-operative follow-up, there were no complications other than wound infection and thoracic tube of the patient was removed. The patient who tolerated enteral food was discharged from hospital with full recovery.
