Preoperative diagnostic criteria for scleroatrophic gallbladder: A systematic review protocol.

BACKGROUND: Although scleroatrophic gallbladder is a rare condition, it presents significant clinical challenges in diagnosis and management. More agreement is needed on this disorder's diagnostic criteria and optimal management approach. We will conduct a systematic review to summarise the scleroatrophic gallbladder's preoperative diagnostic criteria, including imaging modalities. METHODS: A systematic review will be undertaken using the PRISMA guidelines. The protocol has been registered in PROSPERO (CRD42024503701). We will search in Medline (via PubMed), Embase, SCOPUS, the Cochrane Library, and Web of Science to find original studies reporting about scleroatrophic gallbladder or synonymous. Two reviewers will independently screen the titles and abstracts following the eligibility criteria. We will include all types of studies that describe any diagnostic criteria or tools. After retrieving the full text of the selected studies, we will conduct a standardised data extraction. Finally, a narrative synthesis will be performed. The quality of the identified studies will be assessed using the Quality Assessment of Diagnostic Accuracy Studies- 2 tool. DISCUSSION: This systematic review will provide information on the preoperative diagnostic criteria of the scleroatrophic gallbladder and the value of imaging studies in its diagnosis. In addition, this work will aid doctors in the decision-making process for diagnosing scleroatrophic gallbladder and propose treatment approaches to this condition. SYSTEMATIC REVIEW REGISTRATION: The protocol has been registered in PROSPERO (CRD42024503701).

Ventriculo-gallbladder shunt: case series and literature review.

BACKGROUND: The ventriculoperitoneal shunt (VPS) is the gold-standard surgical technique to treat hypertensive hydrocephalus; however, it may fail in 20 to 70% of cases. The present study shows an alternative for patients with contraindications to VPS. METHODS: A case series of nine patients. The medical records of all patients under 17 years of age who underwent ventriculo-gallbladder (VGB) shunt at a pediatric hospital from January 2014 to October 2022 were reviewed. RESULTS: There were 6 (66.7%) males and 3 (33.3%) females. The average age of 73.6 months or 6.1 years at the time of surgery. They had undergone, on average, 5.1 VPS reviews before the VGB shunt. Five (55.5%) had complications of VGB shunt: infection (11.1%), atony (11.1%), hypodrainage (11.1%), and ventriculoenteric fistula (22.2%); all these patients got better at surgical reapproach, and in two of them, the VGB shunt was re-implanted. CONCLUSION: This case series shows a lower risk of death and a similar risk of complications compared to other alternative shunts. This article spotlighted VGB as a viable alternative when VPS fails or has contraindications.

Ventriculo - Gallbladder shunt.

INTRODUCTION: Permanent liquor diversion is associated with a high risk of failure and often requires re-intervention. The ventriculo-gallbladder shunt (VGS) has been recognized as a last-resort alternative for treating hydrocephalus when the peritoneum or other distal sites are no longer suitable for receiving shunts. This article aims to report a case from a neurosurgery referral service in Brazil and review the literature on this issue. METHODS: A systematic literature review was conducted in accordance with the PRISMA statement. The PubMed, Embase, and Web of Science databases were searched for data screening and extraction. The reported case was conducted with ethical approval from the neurosurgical hospital's ethics committee. RESULTS: G.B.S, male, 43 years old, no comorbidities, who has been dealing with a 12-year history of hydrocephalus, with post-surgical chronic fungal meningitis. Two years ago, he underwent a ventriculoatrial shunt (VAS) placement due to multiple ventriculoperitoneal shunt (VPS) failures. Endocarditis was suspected, and the VAS was removed. As an alternative, VGS was implanted 6 months ago, and since then, there has been no need for a new system review. The gallbladder has an absorptive capacity of 1500 cc of liquid daily, which is more than the normal daily production of cerebrospinal fluid (CSF). Therefore, it is a good alternative when the ventriculoperitoneal shunt is not feasible due to postsurgical peritoneal adhesions or when there are contraindications for ventriculoatrial shunts. CONCLUSION: VGS is an alternative for patients who cannot undergo the most common surgical interventions, such as VPS.

Elective Cholecystectomy After Endoscopic Gallbladder Stenting for Acute Cholecystitis: A Propensity Score Matching Analysis.

OBJECTIVE: To investigate the influence of endoscopic gallbladder stenting (EGBS) on subsequent cholecystectomy. We retrospectively compared the surgical outcomes of EGBS, followed by elective cholecystectomy with those of immediate cholecystectomy (IC). PATIENTS AND METHODS: A total of 503 patients were included in this study. Patients who underwent EGBS as initial treatment for acute cholecystitis, followed by elective cholecystectomy, were included in the EGBS group and patients who underwent IC during hospitalization were included in the IC group. Propensity score matching analysis was used to compare the surgical outcomes. In addition, the factors that increased the amount of bleeding were examined by multivariate analysis after matching. RESULTS: Fifty-seven matched pairs were obtained after propensity matching the EGBS group and the IC group. The rate of laparoscopic cholecystectomy in the EGBS versus IC groups was 91.2% versus 49.1% ( P < 0.001). The amount of bleeding was 5 mL in the EGBS versus 188 mL in the IC group ( P < 0.001). In the EGBS and IC groups, multivariate analysis of factors associated with more blood loss revealed IC (odds ratio: 4.76, 95% CI: 1.25-20.76, P = 0.022) as an independent risk factor. CONCLUSION: EGBS as the initial treatment for acute cholecystitis and subsequent elective cholecystectomy after the inflammation has disappeared can be performed in minimally invasive procedures and safely.

Use of endoscopic ultrasound-guided gallbladder drainage as a rescue approach in cases of unsuccessful biliary drainage.

This narrative review provides an overview of the utilization of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) as a salvage approach in cases of unsuccessful conventional management. EUS-GBD is a minimally invasive and effective technique for drainage in patients with acute cholecystitis with high risk of surgery. The procedure has demonstrated impressive technical and clinical success rates with low rates of adverse events, making it a safe and effective option for appropriate candidates. Furthermore, EUS-GBD can also serve as a rescue option for patients who have failed endoscopic retrograde cholangiopancreatography or EUS biliary drainage for relief of jaundice in malignant biliary stricture. However, patient selection is critical for the success of EUS-GBD, and proper patient selection and risk assessment are important to ensure the safety and efficacy of the procedure. As the field continues to evolve and mature, ongoing research will further refine our understanding of the benefits and limitations of EUS-GBD, ultimately leading to improved outcomes for patients.

Influence of Percutaneous Transhepatic Gallbladder Aspiration and Drainage for Severe Acute Cholecystitis on the Surgical Outcomes of Subsequent Laparoscopic Cholecystectomy: Post Hoc Analysis of the CSGO-HBP-017 (CSGO-HBP-017C).

OBJECTIVE: Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS: We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS: No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION: PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

Gallbladder strangulation caused by a fibrotic band due to chlamydia infection: A case report.

Acute cholecystitis, a very common disease, is usually caused by gallstone obstruction of the cystic duct. Meanwhile, strangulated cholecystitis is extremely rare, and it develops when the gallbladder is strangled by a band. It is very similar to gallbladder torsion in terms of imaging findings and obstruction of blood and biliary flow, and it requires emergency surgery. We herein report a case of a 90-year-old woman with gallbladder strangulation caused by a fibrotic band due to a chlamydia infection, and we also reviewed some literature on strangulated cholecystitis.

Decoding the Conundrum: Navigating Intra-operatively Encountered Suspicious Gallbladder Wall Thickening with Laparoscopic Transhepatic Needle Decompression and Beyond Cystic Plate Cholecystectomy.

BACKGROUND: Suspicious gallbladder wall thickening encountered during laparoscopic cholecystectomy poses challenges in its management. This study aims to address this problem by proposing a technique that involves laparoscopic transhepatic needle decompression and modified cystic plate cholecystectomy. METHODS: In this report, we describe the case of a 36-year-old female with symptomatic gallstone disease and ultrasound findings of a well-distended gallbladder with a uniform wall thickness. Diagnostic laparoscopy revealed a distended, tense gallbladder with suspicious areas of thickness. Transhepatic aspiration was performed for gallbladder decompression, followed by modified cystic plate cholecystectomy with preservation of the thin rim of liver tissue over the cystic plate. The gallbladder was removed in a specimen bag, and final histopathology showed a hyalinized gallbladder wall with calcification and pyloric gland metaplasia, with liver tissue adhered to the gallbladder wall (Video). RESULTS: The proposed technique aimed to minimize the risk of bile spillage and violation of oncological planes while maintaining surgical integrity. It offers a middle path between standard and extended cholecystectomy, reducing the chance of over- or under-treatment. This approach ensures patient safety, minimizes the need for conversion to open surgery, and preserves the tumour-tissue interface. CONCLUSION: Intraoperatively encountered suspicious gallbladder wall thickening can be effectively managed with laparoscopic transhepatic needle decompression and modified cystic plate cholecystectomy.

Suturing with or without surgical glue is superior to surgical glue alone for sealing ex vivo swine gallbladders.

OBJECTIVE: To assess the effectiveness of various sealing techniques in cholecystotomies under maximum intraluminal pressure stress using an ex vivo swine model. SAMPLE: 30 gallbladders from different animals were used. METHODS: The experiment was conducted ex vivo, with the formation of 3 groups, each comprising 10 samples. Group 1 utilized a traditional single-layer Cushing suture made from polydioxanone material. Group 2 employed a single layer of Cushing suture, also made from polydioxanone material, but in conjunction with surgical glue (n-butyl cyanoacrylate). Group 3 relied solely on the use of surgical glue (n-butyl cyanoacrylate) for sealing the edges of the surgical wound. The intraluminal pressure was gauged with a pressure transducer. RESULTS: The maximum intraluminal pressures (mean ± SD) sustained in G1, G2, and G3 were, respectively, 48.70 ± 21.32 mm Hg, 110.90 ± 37.52 mm Hg, and 10.9 ± 4.07 mm Hg. Comparisons between groups showed that G2 supported significantly higher pressures (56.1% higher) than G1 (P < .001) and G3 (90.2% higher; P < .001). When G1 was compared with G3, a significantly higher pressure (77.6%) was also observed (P < .01). CLINICAL RELEVANCE: The study's conclusions demonstrated the safest suture techniques for the gallbladder and provided advice regarding the use of surgical glue.

Safety and adverse events of EUS-guided gallbladder drainage using lumen-apposing metal stents and percutaneous cholecystostomy tubes: a systematic review and meta-analysis.

BACKGROUND AND AIMS: EUS-guided gallbladder drainage using lumen-apposing metal stents (EUS-GBD-LAMSs) and percutaneous cholecystostomy for gallbladder drainage (PTGBD) are the alternative treatment modalities in high-risk surgical patients with acute cholecystitis (AC). The aim of this study was to compare the safety of these procedures for AC in surgically suboptimal candidates. METHODS: Six studies compared the 2 groups' early, delayed, and overall adverse events; they also compared length of hospital stay, re-interventions, and re-admissions rate. A random effect model calculated odds ratios (ORs) with a 95% confidence interval (CI). RESULTS: The 2 groups had similar early adverse events; however, EUS-GBD-LAMS was associated with a lower rate of delayed (OR, .21; 95% CI, .07-.61; P ≤ .01) and overall (OR, .43; 95% CI, .30-.61; P ≤ .01) adverse events. Patients with EUS-GBD-LAMSs had a shorter hospital stay than PTGBD. CONCLUSIONS: EUS-GBD-LAMS is a safer option than PTGBD and is associated with a shorter hospital stay in nonsurgical candidates with AC.

Cholecystokinin to Enhance the Safety of Ablation of Liver Tumors Adjacent to the Gallbladder.

This retrospective case review describes the potential for intravenous cholecystokinin (CCK) to improve the safety margin between the hepatic tumor and gallbladder (GB) for hepatic tumor ablation. Eight patients with primary hepatic neoplasms adjacent to the GB underwent CCK administration before ablation. GB volume and contact area measurements were performed before and after CCK administration to assess the degree of contraction. The planned ablation was successful in 7 patients (88%) after CCK administration, although 5 patients (63%) also had hydrodissection. After CCK, the median GB volume reduction was 22%, and tumor contact area with the GB was reduced by 20%. There was no evidence for CCK-related adverse events. CCK administration before ablation of hepatic neoplasms abutting the GB is a safe and simple method that may be an adjunct to needle decompression or hydrodissection of the GB.
