Meta-Analysis
INTRODUCTION
With severely inflamed gallbladders, laparoscopic cholecystectomy can be difficult and may require procedures like subtotal cholecystectomy (SC). Few studies exist comparing SC and total cholecystectomy (TC) in the setting of severe biliary inflammation. This meta-analysis aims to compare SC and TC for difficult gallbladders.
METHODS
Medline-OVID, Embase-OVID, and Cinahl were searched including only studies comparing SC to TC for difficult gallbladders. Primary outcome was CBD injury. Secondary outcomes included bile leak, duodenal injury, retained stone, bleeding, intraabdominal collection, wound infection, reoperation, and mortality.
RESULTS
Ten studies were included. Compared to TC, SC significantly lowered the risk for CBD injury (0 % vs. 1.6 %, RR 0.30, 95%CI 0.10-0.87) but increased risk of bile leaks (RR 3.5, 95%CI 1.79-6.84), postoperative ERCP (RR 2.86, 95%CI 1.53-5.35), intraabdominal collections (RR 2.55, 95%CI 1.32-4.93), and reoperation (RR 2.92, 95%CI 1.14-7.47).
CONCLUSION
SC is a reasonable alternative to difficult gallbladders that may decrease the risk of CBD injuries. Knowing both approaches is crucial to manage the difficult gallbladder while minimizing harm. Further studies are needed to understand the value of SC for difficult cholecystectomy.

Irish Veterinary Journal Sep 2023To the best of our knowledge, this is the first report of female genital system infiltration of T-cell lymphoma in veterinary literature.
BACKGROUND
To the best of our knowledge, this is the first report of female genital system infiltration of T-cell lymphoma in veterinary literature.
CASE PRESENTATION
A 1.5-year-old, intact female Golden Retriever was referred due to melena and hyporexia that lasted for three weeks. Fever (40.5℃), tachycardia, tachypnoea, pale mucous membranes, and purulent vaginal discharge were identified on physical examination. Blood analyses revealed leucocytosis, anaemia, hypoalbuminemia, and increased lactate and C-reactive protein levels. On abdominal radiography, the small intestine was moderately deviated because of an oval-shaped mass (13 cm × 8.7 cm) located in the mid-abdomen. An enlarged tubular-shaped structure that had the opacity of soft tissue located in dorsal to the bladder to the middle of the abdomen, and an oval-shaped mass (5.28 cm × 3.26 cm), which was suspected to be a medial iliac lymph node located at the sixth to seventh lumbar level. Abdominal ultrasonography revealed gas and fluid in the lumen of the uterine horn with a severely thickened wall, round enlarged lymph nodes around the genitourinary system, and free fluid in the abdominal cavity. Based on these results, pyometra was suspected, and an exploratory laparotomy was performed for ovariohysterectomy. The resected ovary and uterus were macroscopically hypertrophied. Histopathological examination of the ovary and uterus revealed neoplastic proliferation of large round cells with strong immunoreactivity for CD3, indicating T-cell lymphoma. Therefore, the young dog was diagnosed with genital lymphoma.
CONCLUSIONS
The present report describes T-cell lymphoma infiltrating the uterus and ovaries in a young dog, which is rarely diagnosed and could aid in the differential diagnosis of genital diseases in young dogs.

OBJECTIVES
Iatrogenic viscus perforation in pediatric gastrointestinal endoscopy (GIE) is a very rare, yet potentially life-threatening event. There are no evidence-based recommendations relating to immediate post-procedure follow-up to identify perforations and allow for timely management. This study aims to characterize the presentation of children with post-GIE perforation to better rationalize post-procedure recommendations.
METHODS
Retrospective study based on unrestricted pooled data from centers throughout Europe, North America, and the Middle East affiliated with the Endoscopy Special Interest Groups of European Society for Paediatric Gastroenterology Hepatology and Nutrition and North American Society for Pediatric Gastroenterology Hepatology and Nutrition. Procedural and patient data relating to clinical presentation of the perforation were recorded on standardized REDCap case-report forms.
RESULTS
Fifty-nine cases of viscus perforation were recorded [median age 6 years (interquartile range 3-13)]; 29 of 59 (49%) occurred following esophagogastroduodenoscopy, 26 of 59 (44%) following ileocolonoscopy, with 2 of 59 (3%) cases each following balloon enteroscopy and endoscopic retrograde cholangiopancreatography; 28 of 59 (48%) of perforations were identified during the procedure [26/28 (93%) endoscopically, 2/28 (7%) by fluoroscopy], and a further 5 of 59 (9%) identified within 4 hours. Overall 80% of perforations were identified within 12 hours. Among perforations identified subsequent to the procedure 19 of 31 (61%) presented with pain, 16 of 31 (52%) presented with fever, and 10 of 31 (32%) presented with abdominal rigidity or dyspnea; 30 of 59 (51%) were managed surgically, 17 of 59 (29%) managed conservatively, and 9 of 59 (15%) endoscopically; 4 of 59 (7%) patients died, all following esophageal perforation.
CONCLUSIONS
Iatrogenic perforation was identified immediately in over half of cases and in 80% of cases within 12 hours. This novel data can be utilized to generate guiding principles of post-procedural follow-up and monitoring.
PLAIN LANGUAGE SUMMARY
Bowel perforation following pediatric gastrointestinal endoscopy is very rare with no evidence to base post-procedure follow-up for high-risk procedures. We found that half were identified immediately with the large majority identified within 12 hours, mostly due to pain and fever.

Randomized Controlled Trial
Investigation of the optimal indocyanine green dose in real-time fluorescent cholangiography during laparoscopic cholecystectomy with an ultra-high-definition 4K fluorescent system: a randomized controlled trial.
This study aimed to investigate the indocyanine green (ICG) dose in real-time fluorescent cholangiography during laparoscopic cholecystectomy (LC) with a 4K fluorescent system. A randomized controlled clinical trial was conducted in patients who underwent LC for treatment of cholelithiasis. Using the OptoMedic 4K fluorescent endoscopic system, we compared four different doses of ICG (1, 10, 25, and 100 µg) administered intravenously within 30 min preoperatively and evaluated the fluorescence intensity (FI) of the common bile duct and liver background and the bile-to-liver ratio (BLR) of the FI at three timepoints: before surgical dissection of the cystohepatic triangle, before clipping the cystic duct, and before closure. Forty patients were randomized into four groups, and 33 patients were fully analyzed, with 10 patients in Group A (1 µg), 7 patients in Group B (10 µg), 9 patients in Group C (25 µg), and 7 patients in Group D (100 µg). The preoperative baseline characteristics were compared among groups (p > 0.05). Group A showed no or minimal FI in the bile duct and liver background, while Group D showed extremely high FIs in the bile duct and in the liver background at the three timepoints. Groups B and C presented with visible FI in the bile duct and low FI in the liver background. With increasing ICG doses, the FIs in the liver background and bile duct gradually increased at the three timepoints. The BLR, however, showed no increasing trend with an increasing ICG dose. A relatively high BLR on average was found in Group B, without a significant difference compared to the other groups (p > 0.05). An ICG dose ranging from 10 to 25 µg by intravenous administration within 30 min preoperatively was appropriate for real-time fluorescent cholangiography in LC with a 4K fluorescent system. Registration: This study was registered in the Chinese Clinical Trial Registry (ChiCTR No: ChiCTR2200064726).

Brush cytology is a sampling technique extensively used for mucosal surfaces, particularly to identify malignancies. A sample is obtained by rubbing the brush bristles over the stricture or lesion several times until cells are trapped. Brush cytology detection rate varies, with malignancy confirmed in 15-65% of cases of adenocarcinoma-associated biliary strictures and 44-80% of cases of cholangiocarcinoma. Despite the widespread use of brush cytology, there is no consensus to date defining the optimal biliary brushing parameters for the collection of suspicious lesions, such as the number of passes, brushing rate, and force applied. The aim of this work is to increase the brush cytology diagnostic yield by elucidating the underlying mechanical phenomena. First, the mechanical interactions between the brush bristles and sampled tissue are analyzed. During brushing, mucus and detached cells are transferred to the space between the bristles through the capillary rise and flow eddies. These mass transfer mechanisms and their dependence on mucus rheology as a function of pH, brush displacement rate, and bristle geometry and configuration are examined. Lastly, results from brushing experiments performed on porcine stomachs are presented. Clinical practitioners from a variety of disciplines can apply the findings of this study to outline clear procedures for cytological brushing to increase the sensitivity and specificity of the brushings.

Review
PURPOSE OF REVIEW
Lumen apposing metal stents (LAMS) have been increasingly used to manage patients with surgically altered anatomy (SAA), who would have otherwise required percutaneous or surgical interventions. Via the creation of de-novo anastomoses, LAMS provides a conduit to access distal parts of the gastrointestinal tract to perform various interventions.
RECENT FINDINGS
Pancreatobiliary (PB) and non-PB interventions are challenging in patients with SAA. Endoscopic ultrasound-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP) (EDGE) and endoscopic ultrasound (EUS)-directed transenteric ERCP (EDEE) are effective procedures that are being increasingly utilized to perform ERCP in patient with Roux-en-Y gastric bypass (RYGB) and non-RYGB SAA, respectively. Furthermore, EUS-directed trans-gastric intervention (EDGI) is a collective term for the non-PB procedures that could be performed in patients with SAA. EDGE/EDEE/EDGI are considered relatively safe procedures, however, intra-procedural stent misdeployement, and long-term ramifications of persistent fistula and stent migration could require endoscopic or, in rare instances, surgical management.
SUMMARY
The advent of LAMS has revolutionized the therapeutic capabilities of EUS, by allowing the creation of new gastrointestinal anastomoses. With the growing body of literature, it is expected that such techniques will be more commonly performed in the community, providing less invasive and more effective treatment options for patients with SAA.

BACKGROUND AND OBJECTIVES
Abdominal radiographs (ARs) are commonly used in the pediatric emergency department (PED). Their low diagnostic accuracy leads to overuse, excess radiation exposure, and increased resource usage. This study aims to assess the diagnostic yield of ARs in the evaluation of intraabdominal pathology in the PED.
METHODS
Retrospective, cross-sectional study of patients aged 0 to 18 years with an AR who visited the PED between 2017 and 2019. Diagnostic yield was analyzed with sensitivity, specificity, positive predictive value, negative predictive value (NPV), and likelihood ratio.
RESULTS
A total of 4288 ARs were identified, with a rate of 6%. The overall abnormal AR rate was 31%. The incidences of an abnormal AR in abdominal pain, vomiting, and constipation were 26%, 37%, and 50%, respectively. There was a 13% rate of clinically significant diagnoses. The AR diagnostic yield showed 44% sensitivity, 70% specificity, 17% positive predictive value, and 90% NPV ( P < 0.05). Unadjusted odds ratio analysis of positive AR and abdominal pain, vomiting, and constipation revealed an odds ratio of 0.68 (95% confidence interval [CI], 0.63-0.75), 1.22 (95% CI, 1.06-1.39), and 1.72 (95% CI, 1.54-1.91), respectively.
CONCLUSIONS
There is a low rate of intraabdominal pathologic processes that an AR can identify. A normal AR does not change patient management, nor does it reduce the need for further radiologic imaging. Despite a good NPV, the AR is not a useful diagnostic tool in the PED because of its limited ability to rule in or rule out clinically significant diagnoses.

Necrotizing enterocolitis (NEC) is a rare but life-threatening diagnosis in infants presenting with bilious emesis, abdominal distension, or bloody stools. Ultrasonography has been advocated as an alternative initial imaging modality to abdominal radiography, and may be superior in the evaluation of NEC. We describe the use of point-of-care ultrasound (PoCUS) in the evaluation of suspected NEC in the emergency department (ED) when the ability to obtain immediate abdominal x-ray (AXR) was delayed due to pandemic conditions. A pre-term infant with history of bowel resection presented with non-bilious emesis, bloody stools, and slight abdominal distension. Evaluation with PoCUS identified pneumatosis intestinalis and pneumoperitoneum, which were confirmed on subsequent AXR. Pneumatosis intestinalis in a neonate is highly suggestive of NEC, but seen by itself, can be associated with milk protein allergy and Food Protein Induced Enterocolitis syndrome (FPIES). Pneumoperitoneum is considered an indication for operative intervention for NEC. The infant was re-admitted to the NICU for suspected NEC. NEC is a rare, but potentially surgical diagnosis in infants as can be FPIES, but not milk protein allergy. NEC can be identifiable using PoCUS to search for a constellation of findings that include pneumatosis intestinalis, pneumoperitoneum, free peritoneal fluid, and portal venous gas. These findings have been previously described in the PoCUS literature for other diseases, but not for a case of suspected NEC presenting to the ED.
