Review
This review aimed to provide an updated and comprehensive review of capsule retention within diverticula, shedding light on the characteristics and management of this rare event in capsule endoscopy. A systematic literature search was conducted across multiple databases. All observational studies that reported capsule retention in a diverticulum among complication and outcomes, as well as case reports and series, were included. Manual cross-checking of references was also performed. Two extractors performed abstract and full-text reviews, as well as data-extraction. We found 167 references from Pubmed, Embase, and Web Of Science. Sixty-five duplicates were removed and another 71 references were excluded. Crosschecking of references found additional two articles. In total, 32 articles were included, resulting in a total of 34 cases of retained capsules in diverticula. The median age was 69 and the majority of the patients were male (76.5%). The most common retention occurred in Meckel's diverticulum (32.4%) followed by Zenker's diverticulum (20.6%). Investigation of capsule retention was done with x-ray (50%) and computed tomography (CT) scan (44.1%). Seventeen cases (50%) were asymptomatic. Resolution of the retention happened with endoscopy (35.3%) and surgical management (32.4%), as well as self-resolution (20.6%). Due to the small number of cases, diverticula are not a risk factor for incomplete capsule endoscopy examination. It affects mainly elderly, male, asymptomatic patients, and typically is diagnosed with x-rays and CT scans. The most common type is Meckel's diverticulum, and endoscopy is the primary management. Capsule endoscopy retentions are extremely rare, with only 34 cases reported since the technology's introduction.

An epiphrenic diverticulum (ED) is a rare pseudodiverticulum commonly located at the lower end of the oesophagus. Surgical treatment is only required in patients with worsening dysphagia or repeated chest infection due to microaspirations, and most patients are now treated with minimally invasive surgery (MIS) using the laparoscopic or thoracoscopic approach. Laparoscopic surgery is considered difficult in the presence of previous perforation of the diverticula owing to the intraperitoneal and mediastinal adhesions and is associated with an increased incidence of complications. We were able to perform a laparoscopic transhiatal resection safely on a patient who had a large ED with a wide neck and dense abdominal and mediastinal adhesions due to previous localized perforation.

BACKGROUND AND AIM
The use of a hood at the tip of a colonoscope enables aspiration, inversion of the diverticulum, and observation of the inside of the diverticulum. In most previous studies, a short hood was used; however, observation of the diverticulum is often inadequate. Long food is promising by previous research, but it was a retrospective study using propensity matching and has some limitations. We compared the identification rate of stigmata of recent hemorrhage (SRH) between the long and standard hoods in cases of suspected colonic diverticular hemorrhage (CDH) to confirm the usefulness of long hood by prospective randomized controlled trial.
METHODS
Eighty patients (42 in the long hood group [L group] and 38 in the short hood group [S group]) who visited the Saitama Medical University Hospital and Tokai University Hachioji Hospital between December 2018 and July 2021 with a chief complaint of bloody stool and suspected CDH, based on the clinical course and imaging studies, were included. Patients were randomly assigned to the L or S group.
RESULTS
Regarding patient background, age was significantly higher in the L group; however, no significant differences were found in medical history or history of antithrombotic medication or nonsteroidal anti-inflammatory drug use. Identification rate of SRH was significantly higher in the L group (58.5%, 24/42 patients) than in the S group (26.3%, 10/38 patients) ( < 0.05). All patients were treated using the clip method, and the rate of rebleeding within 1 month was not significantly different between the two groups.
CONCLUSION
A long hood was more useful compared with a short hood in identifying SRH of CDH (UMIN000034603).

BACKGROUND
While diverticular disease is prevalent in the West, the formation of giant colonic diverticula is rare. To date, approximately 200 cases have been reported, with only a handful treated surgically using a minimally invasive approach. Furthermore, the natural history of giant colonic diverticula is not well documented.
CASE SUMMARY
This report describes the case of a 66-year-old man who developed a giant colonic diverticulum with primary symptoms including dull and chronic pain in the right lower quadrant at presentation. The patient had undergone several computed tomography scans of the abdomen and pelvis over the previous two years, through which the natural history of this rare entity could be retrospectively observed. The patient was successfully treated with a robot-assisted sigmoid colectomy and had an uneventful recovery with resolution of symptoms during the follow-up.
CONCLUSION
This rare case demonstrates the natural history of giant colonic diverticulum formation and supports the feasibility of robot-assisted surgery.

BACKGROUND Virtual reality (VR)-guided GC simulation for patients with anatomical anomalies using cardiac computed tomography (CT) has been recently reported. Rotational atherectomy (RA) for the left circumflex (LCX) ostium is challenging due to the tortuous anatomy, acute angulation, and variable vessel size compared to other lesions. The appropriate positioning and coaxiality of the guide catheter (GC) are key factors for safely performing RA. It would be beneficial if it could be simulated prior to percutaneous coronary intervention (PCI). CASE REPORT We treated a 55-year-old man with angina. We performed coronary angiography and detected an ostial calcified lesion of the LCX. We needed RA for this lesion, but PCI was very difficult and challenging. CT revealed right-sided aortic arch with stenosis of left subclavian artery from the Kommerell diverticulum at the distal part of the aortic arch. Therefore, the approach site for PCI was limited. We simulated the appropriate guide catheter and approach site for PCI by VR. PCI was successfully performed with RA, as in the VR simulation. CONCLUSIONS We successfully performed PCI for an ostial calcified lesion of the LCX in a patient with a right-sided aortic arch. Use of VR-guided GC simulation is a useful new option that can help visualize the anatomy and ensure safe procedures for complex lesions.

Meckel's diverticulum is a developmental GI anomaly. It is a remnant of the omphalomesenteric duct (vitelline duct) and the most common congenital anomaly found in the small intestine. It contains ectopic/heterotopic gastric mucosa in half of the cases. Imaging investigations for diagnosing Meckel's diverticulum may include a plain radiography; however, this has a very limited diagnostic value. A blind-ending fluid-filled structure can sometimes be seen with sonography, but again, this technique's diagnostic value is limited due to multiple factors. A CT scan may be helpful in localizing the bleeding diverticulum, which can be better visualized with CT enterography. Diverticula containing gastric mucosa can be diagnosed with a higher sensitivity with Tc-99 scintigraphy. The typical location of Meckel's diverticulum is within two feet of the ileocecal valve; thus, ectopic gastric mucosal uptake is typically seen in the lower right quadrant in scintigraphy. We present a rare case of Tc-99 pertechnetate scintigraphy showing ectopic gastric mucosa in the upper mid abdomen, which was surgically proven to be at the mid ileum. To our knowledge, there is no ectopic Meckel's diverticulum case published in the literature. Familiarity with this atypical imaging presentation of relatively common ectopic gastric mucosa may help the radiologists in the timely diagnosis and management of the patient.

Review
: The right-sided aortic arch (RAA) is an uncommon variation of the aortic arch (AA), characterized by the aorta crossing over the right main bronchus. In the RAA, the descending aorta can be found on either the right or left side of the spine. The current study comprises a comprehensive retrospective computed tomography angiography (CTA) investigation into the prevalence of the RAA within the Greek population. Additionally, we will conduct a systematic review and meta-analysis to elucidate both common and rare morphological variants of the RAA. This research is significant as it sheds light on the prevalence and characteristics of the RAA in a specific population, providing valuable insights for clinical practice. : Two hundred CTAs were meticulously investigated for the presence of a RAA. In addition, the PubMed, Google Scholar, and Scopus online databases were thoroughly searched for studies referring to the AA morphology. The R programming language and RStudio were used for the pooled prevalence meta-analysis, while several subgroup analyses were conducted. : A unique case of 200 CTAs (0.5%) was identified with an uncommon morphology. The following branches emanated from the RAA under the sequence: the right subclavian artery (RSA), the right common carotid artery (RCCA), the left common carotid artery (LCCA), and the left vertebral artery (LVA) in common origin with the aberrant left subclavian artery (ALSA). The ALSA originated from a diverticulum (of Kommerell) and followed a retroesophageal course. : Sixty-two studies (72,187 total cases) met the inclusion criteria. The pooled prevalence of the RAA with a mirror-image morphology was estimated at 0.07%, and the RAA with an ALSA was estimated at <0.01%. AA anomalies, specifically the RAA, raise clinical interest due to their coexistence with developmental heart anomalies and possible interventional complications. Congenital heart anomalies, such as the Tetralogy of Fallot and patent foramen ovale, coexisted with RAA mirror-image morphology.

OBJECTIVE
The study was to figure out the feasibility, efficacy, and safety of a single-branched stent graft, namely Castor, in combination with fenestration or chimney in the context of aortic arch lesions presenting with aberrant subclavian artery (ASA) and/or Kommerell's diverticulum (KD).
METHODS
All consecutive patients with aortic arch lesions and ASA and/or KD receiving Castor from June 2018 to June 2023 were investigated.
RESULTS
Incorporating 18 patients, the study encompassed 11 cases with KD, 3 cases with dysphagia; 2 cases of right-sided aortic arch with left-sided aberrant left subclavian artery (ALSA), and 16 cases of left-sided aortic arch with right-sided aberrant right subclavian artery (ARSA). The mean operation time was 132±23 minutes. The mean measured proximal aortic diameter was 30.9±1.6 mm, and proximal diameter of Castor stent was 34 (32, 34.5) mm, with oversize of 9.1±1.6%; the mean measured branch diameter was 8.8±0.97 mm, and branch diameter of Castor stent was 10 (8, 10) mm, with oversize of 0.86±0.57 mm. Technical success rate was 100%, and no in-hospital mortality, no stroke, and no endoleak were identified. One (5.6%) case with spinal cord ischemia and one (5.6%) case with poor healing of operative site were identified. During the follow-up period, no aortic-related death or secondary intervention was recorded. The maximal aortic diameter was significantly reduced at the sixth postoperative month (p=0.031); KD diameter was significantly reduced at the third (p=0.001) and sixth (p<0.001) postoperative month.
CONCLUSION
Totally endovascular repair of aortic arch lesions with ASA and KD via Castor stent in combination with fenestration or chimney is feasible, effective, and safe, which can achieve an encouraging medium-term outcome and provide excellent remodeling at the lesions.
CLINICAL IMPACT
Single branched stent in combination with fenestration or chimney achieved a sufficient proximal landing zone and provided an encouraging medium-term outcome in this retrospective review of 18 patients receiving endovascular treatment of pathological aortic arch with aberrant subclavian artery and/or Kommerell's diverticulum. The authors suggest this time-saving and efficient technique to establish systematic experience for the treatment in this kind of patients.

INTRODUCTION
Acquired bladder diverticula (BD) are associated with bladder outlet obstruction. The aim of our study is to analyse the improvement in lower urinary tract symptoms (LUTS) in patients who underwent robot-assisted bladder diverticulectomy (RABD) combined with transurethral prostatectomy (TURP).
MATERIAL AND METHODS
A prospectively single-centre, single surgeon cohort of four patients with posterolateral BD due to bladder outlet obstruction (BOO) undergoing RABD combined with TURP between 2018 and 2023 was analysed.
RESULTS
Median age and maximum BD diameter were 73.5 years and 16 cm, respectively. All patients had severe LUTS and elevated postvoid residual (PVR). Preliminary uroflowmetry revealed bladder outlet obstruction with a median of maximum urine flow rate of 8.5 ml/s. The median operative time and blood loss were 212 min and 100 ml, respectively. No intraoperative complications were recorded. The median length of stay was 4 days. The International Prostate Symptom Score (IPSS) and PVR were compared between baseline, 1 month and 6 months after surgery. IPSS significantly decreased from 24 (IQR 24-25) preoperatively compared to the postoperative, at 1 month follow up 7 (IQR 6-8) ( < 0.0001). PVR significantly decreased too from 165 (IQR 150-187) to 35 ml (IQR 25-42) ( < 0.0001). In transitioning from the 1-month follow-up to the 6-month follow-up, no substantial statistical improvement was observed.
CONCLUSION
Concomitant performance of TURP with RABD is feasible and safe. Diverticulectomy in addiction at the endoscopic procedure should be discussed with patients who have obstructive lower urinary tract symptoms as viable alternative to single procedure individually performed.

Littre's umbilical hernia (UH) is a rare disease, the third most common Littre hernia. Most case reports interest adult patients. We reported the case of a four-year-old girl with anemia and symptomatic UH, with an incidentally diagnosed Meckel's diverticulum (MD) containing pancreatic ectopic tissue. We reviewed case reports on Littre's umbilical hernia without a date or language restriction. Including our patient, 21 cases were reviewed, of whom 15 (71.4%) were adults and 13 (61.9%) were males. Complicated umbilical hernia occurred in 13 patients (61.9%) and symptomatic MD in two children (9.5%). Investigations preoperatively diagnosed two patients (9.5%). Eighteen patients (85.7%) underwent open surgery, Meckel's diverticulum removal was performed in 18 patients (85.7%), and primary umbilical hernia repair was performed in 16 (76.2%). Ectopic tissue was present in four patients (19.1%), and long-term outcomes were excellent in all patients.
