BACKGROUND
Abnormal colonic pressure profiles have been associated with an increased risk of colonic diverticulosis. A surgical history is a known risk factor for abdominal adhesions and these may lead to increased intraluminal colonic pressure.
AIM
To assess whether previous abdominal surgery is associated with colonic diverticulosis or diverticulitis.
METHODS
We analyzed data from a study of patients undergoing colonoscopy for different indications from 2020 through 2021. Patients completed a structured questionnaire concerning previous abdominal surgeries, dietary and lifestyle exposures including smoking, alcohol use and co-morbidities.
RESULTS
Three hundred and fifty-nine patients were included in the study. The mean age was 67.6 and 46% were females. Diabetes mellitus, hypertension, ischemic heart disease, chronic obstructive pulmonary disease, chronic renal failure, and body mass index were similar in the diverticulosis and control groups. The overall prevalence of colonic diverticulosis was 25% (91/359) and 48% of the patients had previous abdominal surgery. As expected, the prevalence of diverticulosis increased with age. There was no difference in the rate of previous abdominal surgery between patients with or without diverticulosis (49% 47%, = 0.78). In regards to specific surgeries, inguinal hernia repair was significantly associated with diverticulosis (52% 20%, = 0.001), but not diverticulitis. In contrast, appendectomy was not associated with diverticulosis (6% 14%, = 0.048).
CONCLUSION
These findings suggest that post-operative abdominal adhesions inducing high colonic intraluminal pressures do not appear to be the mechanism for diverticula formation. Rather, inguinal hernia and diverticulosis may share similar connective tissue pathologies with no causative relationship between them.

Review
The CT Colonography Reporting and Data System (C-RADS) has withstood the test of time and proven to be a robust classification scheme for CT colonography (CTC) findings. C-RADS version 2023 represents an update on the scheme used for colorectal and extracolonic findings at CTC. The update provides useful insights gained since the implementation of the original system in 2005. Increased experience has demonstrated confusion on how to classify the mass-like appearance of the colon consisting of soft tissue attenuation that occurs in segments with acute or chronic diverticulitis. Therefore, the update introduces a new subcategory, C2b, specifically for mass-like diverticular strictures, which are likely benign. Additionally, the update simplifies extracolonic classification by combining E1 and E2 categories into an updated extracolonic category of E1/E2 since, irrespective of whether a finding is considered a normal variant (category E1) or an otherwise clinically unimportant finding (category E2), no additional follow-up is required. This simplifies and streamlines the classification into one category, which results in the same management recommendation.

A 66-year-old male from Venezuela with history of high blood pressure and diverticulosis is being studied on an outpatient basis for abdominal pain and weight loss of several months of evolution. He presented to the emergency department due to worsening abdominal pain in the last 48 hours and fever. His abdomen was mildly tender to palpation in the left hypochondrium but did not exhibit signs of peritonitis. An abdominal x-ray was performed, revealing an oval, smooth-walled mass located in the left upper quadrant that contained a gas-fluid level. An outpatient abdominal CT scan performed two months earlier showed an intraabdominal, 14.8x10x16cm air cystic lesion, proposing giant colonic diverticulum as first diagnostic possibility. Given the findings of the abdominal x-ray, urgent abdominal CT was requested (image 3) with results suggestive of sigmoid-dependent giant diverticulum, complicated by probable superinfection and torsion of the sigma at its base. Considering the suspected diagnosis, the patient underwent diverticulectomy, demonstrating purulent content inside. Histopathology confirmed the diagnosis. Evolution after surgery was favourable and the patient was discharged on the sixth postoperative day.

Laimer's diverticulum (LD) is a very rare clinical entity originating between the cricopharyngeus muscle (CPM) and circular muscular fibers of the esophagus. Its diagnosis and management remain to be elucidated. This article summarizes our experience in its diagnosis and open surgical management. A retrospective review of LD cases treated at our tertiary medical institution was conducted between July 2018 and May 2023. The clinical and demographic data were retrieved from case notes. Three cases were included in this review. There were 2 male patients and 1 female patient. The average and median ages were 47.3 and 54 years, respectively. Presenting symptoms included hoarseness, pharyngeal foreign body sensation, and neck mass. All 3 diverticula were on the left side, with the first 2 cases discovered accidentally on gastric endoscopic or cervical MRI examinations. After evaluating esophageal swallowing with barium sulfate or urografin contrast media, all the patients consented to undergo an open surgical procedure. During surgical exploration, the diverticula were found to be on the posterior part of the cervical esophagus, below CPM, and away from the recurrent laryngeal nerve, and only then, could the diagnosis of LD be established. Then, diverticulectomy and manual suturing of the esophagus was performed. Recovery of all 3 patients was uneventful. Nasogastric tube feeding lasted 7 to 12 days until esophageal examinations demonstrated no leak, and then, oral liquid feeding resumed. The median duration of follow-up was 50 months. No recurrence of symptoms or diverticulum was observed, and the swallowing function of all 3 patients was excellent. An open surgical approach is not only important for the diagnosis of LD, but can also be utilized as a safe and effective treatment.

Review
OBJECTIVE
The aim of this case series is to report feasibility, efficiency, and safety of fenestrated physician-modified endografts (PMEGs) in aortic arch pathologies with aberrant right subclavian artery (ARSA) and/or Kommerell's diverticulum (KD).
METHODS
All consecutive patients with ARSA and/or KD who underwent hybrid aortic arch repair combined with homemade fenestrated stent-graft from 2018 to 2022 were reviewed.
RESULTS
Six patients with ARSA and/or KD underwent hybrid surgery for aortic repair, 4 of whom were men, with a mean age of 49 years. Furthermore, 2 of them were symptomatic with dysphagia, 1 was taken in emergency, 1 had a bovine arch and a KD, and 2 had right descending thoracic aortas. The mean operation time was 138 (111-216) minutes. In addition, 83% of the homemade grafts were double fenestrated. All the proximal landings were in zone 0; the mean proximal aortic diameter was 29 (23-34) mm. The range of diameters for the endografts were 24 to 38 mm. There was a 100% technical success, with 0% 30 days mortality, no stroke, and no endoleak. During the follow-up, no aortic-related death or secondary intervention was required and all supra-aortic vessels remain patent.
CONCLUSION
Hybrid aortic arch repair, with fenestrated PMEGs for ARSA and/or KD, is associated with acceptable early and midterm major morbidity and mortality.
CLINICAL IMPACT
This retrospective case series analyzed outcomes in 6 patients with an aberrant right subclavian artery and/or Kommerell's diverticulum treated with fenestrated PMEGs during an average 16 month follow-up. The case series suggests that the use of these fenestrated PMEGs for the management of patients with an aberrant right subclavian artery is a safe, effective and durable method in the medium-term.

Calyceal diverticulum (CD) is a rare anatomic anomaly with an incidence of 0.2% to 0.6% in the patients undergoing renal imaging. They are considered benign lesions and malignancy is exceedingly rare. For diagnosis it is suggested to perform a multiphasic contrast-enhanced computed tomography (CT) evidencing a diverticulum of the pelvicalyceal system with thin-walled cavities communicating with the central collecting system. However, they can be usually mistaken as kidney cancers leading to unjustified nephrectomy. Here, we present a case of a 34-year-old patient who underwent surgery in 2022 due to suspected kidney cancer and histopathological analysis surprisingly reported a CD.

RATIONALE AND OBJECTIVES
An anatomic association between ductus diverticulum and the primary entry tear in type B aortic dissection was observed. The aim was to reveal the association between ductus diverticulum and acute type B aortic dissection.
MATERIALS AND METHODS
A matched case-control study was conducted. Case subjects were extracted from consecutive patients with aortic dissection in the emergency department during 2019; the control subjects were extracted from consecutive patients without major aortic disease during 2019. 1:1 matching was performed for age, sex, and comorbidity, the prevalence of ductus diverticulum was compared, and conditional logistic regression was performed to reveal the association of ductus diverticulum and acute type B aortic dissection. In addition, the anatomic association between the ductus diverticulum and the primary entry tear was assessed in extracted cases, and baseline parameters were compared between dissection patients with or without ductus diverticulum.
RESULTS
128 cases and 402 control subjects were extracted. 86 pairs were formed after matching, and the proportion of ductus diverticulum (19.8% vs 1.2%, p < 0.001) was higher in the case group. Conditional logistic regression revealed ductus diverticulum(OR = 22.04, 95%CI: 2.81-172.76, p = 0.003) as an independent predictor for acute type B aortic dissection. Besides, the ductus diverticulum has an anatomic association with the primary entry tear (OR = 4.22, 95%CI: 1.46-12.25, p = 0.008), and dissection patients with ductus diverticulum were younger (47.9 vs 54.4, p = 0.015) than dissection patients without ductus diverticulum.
CONCLUSION
Ductus diverticulum is common in acute type B aortic dissection and is independently associated with acute type B aortic dissection.

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.

BACKGROUND
Laparoscopic surgery for pediatric intussusception has recently become more common as an alternative to open surgery. However, the differences in outcomes between laparoscopic and open surgery remain unclear. Thus, this study aimed to compare short-term surgical outcomes and recurrence rates between patients treated with laparoscopic and open surgery for pediatric intussusception.
METHODS
Patients aged <18 years who underwent laparoscopic (n = 192) and open (n = 416) surgery for intussusception between April 2016 and March 2021 were retrospectively identified using a Japanese nationwide inpatient database. Propensity-score overlap weighting analyses were conducted to compare the outcomes between the laparoscopic and open surgery groups. The outcomes included in-hospital morbidity, reoperation, readmission for intussusception, bowel resection, the diagnosis of Meckel's diverticulum, duration of anesthesia, postoperative length of hospital stay, and total hospitalization costs.
RESULTS
The laparoscopic surgery group was older, heavier, and had fewer congenital malformations and emergency admissions than the open surgery group did. Overlap weighting analyses showed no significant differences in in-hospital morbidity (odds ratio [95% confidence interval], 0.88 [0.35-2.23]), reoperation (1.88 [0.24-14.9]), readmission for intussusception within 30 days (0.80 [0.12-5.30]) and 1 year (0.90 [0.28-2.93]), bowel resection (0.69 [0.46-1.02]), the diagnosis of Meckel's diverticulum (0.97 [0.50-1.90]), duration of anesthesia (difference, 11 [-1-24] minutes), postoperative length of stay (difference, -1.9 [-4.2-0.4] days), or total hospitalization costs (difference, 612 [ -746-1970] US dollars) between the groups.
CONCLUSIONS
In this large nationwide cohort, no significant differences in outcomes were observed between laparoscopic and open surgery. Laparoscopic surgery is an acceptable treatment option for pediatric intussusception.

A 73-year-old male patient presented to the Emergency Department with history of weight loss, dysphagia, and recurrent fever. The initial chest radiograph showed a mediastinal hypotransparency and to the complaints of dysphagia the patient did a barium swallow test that revealed a giant Zenker diverticulum. Apart from mildly elevated inflammatory markers and despite the extensive investigation of recurrent fever, no other relevant features were found either in blood analysis, microbiological cultures or computerized tomography. He was submitted to surgical intervention, with no recurrence of fever afterwards. It was assumed that food debris and possible microaspirations were responsible for the recurrence of fever and elevation of inflammatory markers. The patient eventually died due to late complications of surgery. Although recurrent fever is frequently linked to systemic disease, the presence of such a giant diverticulum was probably causing an inflammatory response that is usually not seen in these conditions.
