Clinical Trial
BACKGROUND
Magnetically assisted capsule endoscopy (MACE) showed the feasibility for upper gastrointestinal examination. To further enhance the performance of conventional MACE, it is necessary to provide quality-improved and three-dimensional images. The aim of this clinical study was to determine the efficacy and safety of novel three-dimensional MACE (3D MACE) for upper gastrointestinal and small bowel examination at once.
METHODS
This was a prospective, single-center, non-randomized, and sequential examination study (KCT0007114) at Dongguk University Ilsan Hospital. Adult patients who visited for upper endoscopy were included. The study protocol was conducted in two stages. First, upper gastrointestinal examination was performed using 3D MACE, and a continuous small bowel examination was performed by conventional method of capsule endoscopy. Two hours later, an upper endoscopy was performed for comparison with 3D MACE examination. The primary outcome was confirmation of major gastric structures (esophagogastric junction, cardia/fundus, body, angle, antrum, and pylorus). Secondary outcomes were confirmation of esophagus and duodenal bulb, accuracy for gastric lesions, completion of small bowel examination, 3D image reconstruction of gastric lesion, and safety.
RESULTS
Fifty-five patients were finally enrolled. The examination time of 3D MACE was 14.84 ± 3.02 minutes and upper endoscopy was 5.22 ± 2.39 minutes. The confirmation rate of the six major gastric structures was 98.6% in 3D MACE and 100% in upper endoscopy. Gastric lesions were identified in 43 patients during 3D MACE, and 40 patients during upper endoscopy (Sensitivity 0.97). 3D reconstructed images were acquired for all lesions inspected by 3D MACE. The continuous small bowel examination by 3D MACE was completed in 94.5%. 3D MACE showed better overall satisfaction (3D MACE 9.55 ± 0.79 and upper endoscopy 7.75 ± 2.34, p<0.0001). There were no aspiration or significant adverse event or capsule retention in the 3D MACE examination.
CONCLUSIONS
Novel 3D MACE system is more advanced diagnostic modality than the conventional MACE. And it is possible to perform serial upper gastrointestinal and small bowel examination as a non-invasive and one-step test. It would be also served as a bridge to pan-endoscopy.

Adult idiopathic hypertrophic pyloric stenosis (AIHPS) is a rare entity first described by Cruveilhier in 1835. There are only approximately 200 cases reported in the English literature to date. Histologically, it may be mistaken for spindle cell neoplasms such as gastrointestinal stromal tumour (GIST). Patients with AIHPS usually present with early satiety, abdominal fullness, postprandial vomiting, epigastric pain, and eructations. Adult intussusception is rare and only accounts for 5% of all intussusceptions. Gastroduodenal intussusception is one of the rare types of adult intussusception. This is more likely to occur when a benign or malignant stomach lesion acts as a lead point. We report a case of AIHPS in a 70-year-old lady presenting with gastroduodenal intussusception. An oesophagogastroduodenoscopy (OGDS) was performed, and it revealed a diffusely thickened and narrowed pyloric antrum. A contrasted computed tomography (CECT) of the thorax and abdomen showed a distended stomach with circumferential thickening of the pylorus. The pre-pyloric antrum was intussuscepting into the pylorus, and the apex is seen within the first part of duodenum. She underwent distal gastrectomy with a Roux-en-y reconstruction via laparoscopic approach and was discharged well. AIHPS is a rare condition and should be a differential in adults presenting with gastric outlet obstruction. We believe in cases of AIHPS presenting with gastroduodenal intussusception, a distal gastrectomy with reconstruction is a reasonable approach. A multidisciplinary approach is essential to obtain the best outcome.

Gastric cancer (GC) is a globally prevalent and deadly malignancy often diagnosed at advanced stages, which can be accompanied by liver metastases. Conventional chemotherapy is contraindicated in patients with severe liver failure because several chemotherapeutic agents are metabolized by the liver. The present study reports on the successful use of nivolumab in a patient with advanced GC and severe liver failure owing to multiple liver metastases. A 57-year-old man was admitted to Shimane Prefectural Central Hospital (Izumo, Japan) with a 2-week history of appetite loss and jaundice. An upper gastrointestinal endoscopy revealed advanced GC (type IV). Computed tomography examination confirmed wall thickening of the gastric pylorus and the presence of multiple liver metastases. A gastric mucosal biopsy confirmed the diagnosis of HER2-positive gastric adenocarcinoma. S-1 + cisplatin chemotherapy was initiated but had to be halted due to the rapid deterioration in liver function, ultimately leading to acute liver failure. The patient was discharged from the hospital under palliative care. The patient was referred to Shimane University Hospital (Izumo, Japan) for a second consultation. Upon admission, the patient presented with severe liver failure, a Child-Pugh score of 10 (Class C), elevated total bilirubin levels of 13.9 mg/dl (normal range: <1.8 mg/dl) and elevated CEA and CA19-9. Nivolumab treatment was initiated, and notably, there was a substantial reduction in bilirubin levels, an improvement in liver function after a single cycle and a partial response observed in imaging studies. Despite the initial poor prognosis, the patient achieved long-term survival, ultimately succumbing to the illness 2 years and 6 months following the initiation of treatment. The present case underscores the potential of immune checkpoint inhibitors, such as nivolumab, in the treatment of patients with cancer and severe liver failure. It also challenges the conventional constraints of chemotherapy, offering a promising direction for future research in this area.

Gastric volvulus is a rare condition determined by the rotation of one part of stomach around another. Stomach can rotate around its longitudinal or short axis or both. The presentation can be acute, subacute and chronic due to twisting and untwisting andimaging should be performed in the acute phase. MDCT shows high accuracy in thediagnosis and definition of gastric volvulus being the preferred diagnostic test in emergency settings. Gastric volvulus may be associated or determined by pre-existing hiatal hernia and accurate analysis of CT signs may be evaluated on order to differentiate between a stomach in an abnormal position and a volvulus.At CT, a displaced antrum at the same level or cranial to the fundus and a transition point at the pylorus is diagnostic for mesenteroaxial volvulus. We present a case of a 70 years old woman with mesenteroaxial volvulus in hiatal hernia.

An 83-year-old male underwent three transgastric punctures with endoscopic ultrasound-guided fine-needle aspiration for the examination of a pancreatic body tumor. After a diagnosis of resectable pancreatic cancer and undergoing distal pancreatectomy, the patient was administered postoperative adjuvant chemotherapy with oral S-1 for 6 months, and carcinoembryonic antigen and carbohydrate antigen 19-9 levels were bimonthly evaluated. Carbohydrate antigen 19-9 levels continually increased to 4638.1 U/mL at 45 months post-fine-needle aspiration. Endoscopic ultrasound-guided showed a 25 mm low-echoic, irregularly shaped, and heterogeneous tumor with clear margins protruding from the mucosa outside the gastric wall, and biopsy confirmed adenocarcinoma. Since the immunostaining findings of the specimen matched those of the previously resected specimen, needle tract seeding (NTS) due to puncture of the pancreatic cancer was identified as the cause. After a pylorus-preserving gastrectomy at 46 months post-fine-needle aspiration, postoperative chemotherapy initiation, comprising gemcitabine and nab-paclitaxel, was initiated; however, the patient died despite these interventions as he developed multiple peritoneal dissemination. Although rare, the incidence of NTS will increase in the future owing to the expected extended survival in post-pancreatic cancer resection cases. We suggest regular upper gastrointestinal endoscopy and endoscopic ultrasound-guided evaluations for patients who are at risk for NTS can facilitate early detection. Furthermore, it is extremely relevant to share experiences of encountered NTS cases in practice and extend knowledge of its varying endoscopic appearances.

RATIONALE
Inflammatory fibroid polyp (IFP), also known as Vanek tumor, is a rare, benign gastrointestinal lesion characterized by its inflammatory and fibroid histological features. IFP is often discovered incidentally during endoscopic examinations. It is exceedingly rare for an IFP to prolapse into the duodenum and results in incomplete obstruction of the pylorus.
PATIENT CONCERNS
A 64-year-old male patient was admitted to the hospital with recurrent episodes of melena over a 6-month period, along with complaints of dizziness and fatigue in the past 10 days.
DIAGNOSES
Gastroscopy showed a giant polypoid mass on the posterior wall of the gastric antrum, prolapsing into the duodenum. Abdominal computer tomography (CT) confirmed the tumor protruding into the duodenum. Pathologic examination of the resected specimen confirmed the IFP diagnosis.
INTERVENTIONS
The giant tumor was completely and successfully excised using endoscopic submucosal dissection (ESD). After the surgery, the patient underwent acid suppression and fluid replenishment therapy.
OUTCOMES
The patient responded well to ESD and was discharged in stable condition. As of the submission of the case report, there has been no recurrence of the tumor after a 5-month follow-up, and the patient is still under follow-up.
LESSONS
While IFPs have traditionally been managed surgically, ESD demonstrates promising treatment outcomes, avoiding the need for surgical distal gastrectomy, and emerges as a safe and effective treatment option.

Comparative Study
Equal short-term outcomes of intracorporeal mechanical gastrogastrostomy in laparoscopic pylorus-preserving gastrectomy for cT1N0 gastric cancer in the middle stomach compared with the extracorporeal hand-sewing method.
BACKGROUND
Intracorporeal mechanical gastrogastrostomy (IMG) techniques have recently been developed and their short-term safety was presented in their initial evaluation. However, whether they are comparable to extracorporeal hand-sewing gastrogastrostomy (EHG) remains unclear. The aim of the study is to establish the safety of IMG in totally laparoscopic pylorus-preserving gastrectomy (TLPPG) compared to EHG in laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG).
METHODS
We retrospectively analyzed the short-term outcomes of patients with middle-third early gastric cancer who underwent LAPPG or TLPPG between 2005 and 2022. The primary objective of this study was to evaluate the non-inferiority of IMG to EHG in terms of safety, with the primary endpoint being the risk difference in anastomosis-related complications (ARCs). The sample size required to achieve a statistical power of 80% for the non-inferiority test was 971 with a one-sided alpha level of 5% and non-inferiority of 5%.
RESULTS
The analysis included a total of 1,021 patients who underwent LAPPG or TLPPG during the study period. Among them, 488 patients underwent EHG, while 533 underwent IMG. The incidences of ARCs were 11.3% and 11.4% in EHG and IMG, respectively. The observed difference in incidence was 0.0017 (90% confidence interval - 0.0313 to 0.0345), which statistically demonstrated the non-inferiority of IMG to EHG in the incidence of ARCs. Among other complications, the incidence of wound infection in IMG was lower than that in EHG.
CONCLUSION
IMG is safe regarding ARCs compared with EHG. These results will encourage surgeons to introduce IMG for patients with early middle gastric cancer.
