\Prompt and accurate diagnosis is critical in the treatment of acute cholecystitis. Diffusion-weighted whole-body magnetic resonance imaging with background body signal suppression/T2 image fusion (DWIBS/T2) identifies areas with high signal intensity, corresponding to inflammation. In the present study, the records and images of patients with acute cholecystitis who underwent DWIBS/T2 between January 2013 and March 2014 were retrospectively analyzed. A total of 11 patients with acute cholecystitis were enrolled. In one patient, DWIBS/T2 identified a thickened wall and high signal intensity, with high signal intensity in the pericholecystic space that suggested localized peritonitis. Positive DWIBS/T2 results indicating acute cholecystitis were obtained in 10/11 patients, with a sensitivity of 90.9%. In addition, wall thickening and high signal intensity were absent in DWIBS/T2 images when wall thickening was not detected by computed tomography. Wall thickening and high signal intensity was attenuated when patients with acute cholecystitis were clinically treated. These data suggest that a thickened gallbladder wall and high signal intensity are indicative of acute cholecystitis and that DWIBS/T2 may be a useful technique in evaluating the severity of acute cholecystitis.

The aim of this article is to propose new criteria for the diagnosis and severity assessment of acute cholecystitis, based on a systematic review of the literature and a consensus of experts. A working group reviewed articles with regard to the diagnosis and treatment of acute cholecystitis and extracted the best current available evidence. In addition to the evidence and face-to-face discussions, domestic consensus meetings were held by the experts in order to assess the results. A provisional outcome statement regarding the diagnostic criteria and criteria for severity assessment was discussed and finalized during an International Consensus Meeting held in Tokyo 2006. Patients exhibiting one of the local signs of inflammation, such as Murphy’s sign, or a mass, pain or tenderness in the right upper quadrant, as well as one of the systemic signs of inflammation, such as fever, elevated white blood cell count, and elevated C-reactive protein level, are diagnosed as having acute cholecystitis. Patients in whom suspected clinical findings are confirmed by diagnostic imaging are also diagnosed with acute cholecystitis. The severity of acute cholecystitis is classified into three grades, mild (grade I), moderate (grade II), and severe (grade III). Grade I (mild acute cholecystitis) is defined as acute cholecystitis in a patient with no organ dysfunction and limited disease in the gallbladder, making cholecystectomy a low-risk procedure. Grade II (moderate acute cholecystitis) is associated with no organ dysfunction but there is extensive disease in the gallbladder, resulting in difficulty in safely performing a cholecystectomy. Grade II disease is usually characterized by an elevated white blood cell count; a palpable, tender mass in the right upper abdominal quadrant; disease duration of more than 72 h; and imaging studies indicating significant inflammatory changes in the gallbladder. Grade III (severe acute cholecystitis) is defined as acute cholecystitis with organ dysfunction.

The aim of this study was to evaluate the surgical outcomes of laparoscopic cholecystectomy (LC) in patients who were diagnosed with severe acute cholecystitis (SAC) and to clarify the useful treatment modalities of SAC. Of 112 patients who presented SAC, we selected 99 patients and divided them into 3 groups: 37 patients who underwent preoperative percutaneous transhepatic gallbladder drainage (PTGBD; group 1), 62 patients with SAC but not indicated for PTGBD (group 2), and 59 patients with acute and chronic cholecystitis (group 3). The conversion rate was 2.7% (1/37) in group 1, 6.5% (4/62) in group 2, and 1.7% (1/59) in group 3. In groups 1 and 2, the postoperative stay and operative time were longer than those in group 3 with significant difference, respectively (P < 0.05). In group 2, there was correlation not only between postoperative stay and age but also between postoperative stay and ASA class (P < 0.05). In group 2, there was no correlation between time to operation and operative time and also between time to operation and postoperative stay, however, there was surprisingly significant correlation between time to operation and conversion rate in SAC (P = 0.018). In conclusion, PTGBD should selectively be performed in patients with severe comorbidities rather than improving surgical outcomes of LC for severe acute cholecystitis. If patients are not indicated for PTGBD, an early laparoscopic cholecystectomy is recommended because it can decrease conversion rate, although it cannot decrease operative time and postoperative stay.

Abstract The Tokyo Guidelines 2013 (TG13) for acute cholangitis and cholecystitis were globally disseminated and various clinical studies about the management of acute cholecystitis were reported by many researchers and clinicians from all over the world. The 1 st edition of the Tokyo Guidelines 2007 ( TG 07) was revised in 2013. According to that revision, the TG 13 diagnostic criteria of acute cholecystitis provided better specificity and higher diagnostic accuracy. Thorough our literature search about diagnostic criteria for acute cholecystitis, new and strong evidence that had been released from 2013 to 2017 was not found with serious and important issues about using TG 13 diagnostic criteria of acute cholecystitis. On the other hand, the TG 13 severity grading for acute cholecystitis has been validated in numerous studies. As a result of these reviews, the TG 13 severity grading for acute cholecystitis was significantly associated with parameters including 30‐day overall mortality, length of hospital stay, conversion rates to open surgery, and medical costs. In terms of severity assessment, breakthrough and intensive literature for revising severity grading was not reported. Consequently, TG 13 diagnostic criteria and severity grading were judged from numerous validation studies as useful indicators in clinical practice and adopted as TG 18/ TG 13 diagnostic criteria and severity grading of acute cholecystitis without any modification. Free full articles and mobile app of TG18 are available at: http://www.jshbps.jp/modules/en/index.php?content_id=47 . Related clinical questions and references are also included.

Introduction The revised Tokyo Guidelines include criteria for determining the severity of acute cholecystitis with treatment algorithms based on severity. The aim of this study was to investigate the relationship of the revised Tokyo Guidelines severity grade to clinical outcomes of cholecystectomy for acute cholecystitis. Methods We identified 66 patients with acute cholecystitis from a prior study of difficult cholecystectomy cases. We examined the relationship between severity grade and multiple variables related to perioperative and postoperative outcomes. Results A more severe revised Tokyo Guidelines grade was associated with a higher number of complications ( p ?=?0.03) and a higher severity of complications ( p ?=?0.01). Severity grade did not predict operative time, estimated blood loss, intensive care unit admission or length of stay. Compared to planned open cholecystectomy, intended laparoscopic cholecystectomy was associated with significantly fewer total and Clavien–Dindo grade 3 complications, fewer intensive care unit admissions, and shorter length of stay ( p values range from 0.03 to 收起

OBJECTIVE: This study aimed to evaluate the incidence and risk factors for acute cholecystitis (AC) in the late phase of severe acute pancreatitis (SAP). METHODS: A review of patients with SAP from January 2008 to December 2009 was performed. Clinical characteristics were compared between patients with AC in the late phase and those without. Risk factors for AC were analyzed using a logistic regression analysis. Receiver operating characteristic curve was used to estimate the predictive value of the risk factors. RESULTS: A total of 269 cases were included. Twenty-seven episodes of AC in the late phase were identified. Patients with AC had higher computed tomography severity index and Acute Physiology and Chronic Health Evaluation (APACHE) II score, as well as higher rate of intraabdominal hypertension, infective pancreatic necrosis (IPN) of the pancreas head, fistula, abdominal bleeding, mechanical ventilation, and prolonged enteral nutrition (EN) via jejunal tube. Independent risk factors for AC, based on the results of logistic regression analysis, included higher APACHE II score, prolonged EN via jejunal tube, and IPN of the pancreas head. CONCLUSIONS: Approximately 10% of patients with SAP will develop AC in the late phase. Risk factors include higher APACHE II score, prolonged EN via jejunal tube, and IPN of the pancreas head.

Purpose: Acute cholecystitis (AC) affects 50-200 000 patients per year. Early surgery is the treatment of choice for AC. Therefore, timely diagnosis is important to begin proper management. Recently, emergency departments have adopted point-of-care ultrasound (POCUS) for the initial evaluation of AC. The accuracy of POCUS for AC has not been well studied. Methods: Patients receiving POCUS for evaluation of AC in the emergency department at our tertiary care institution for 2 years were considered. Patients with previous biliary diagnoses were excluded. Patients were deemed to have AC from a recorded POCUS result or 2/3 of the following POCUS findings: pericholecystic fluid, gallbladder wall hyperemia, and sonographic Murphy's sign. Formal ultrasound and final diagnosis from surgical and pathology reports were used as gold standards for comparison. Results: In total, 147 patients met inclusion criteria. POCUS had a sensitivity and specificity of .4 (95% CI:. 1216-.7376) and .99 (.9483-.9982), respectively, when compared to a final diagnosis and .33 (.0749-.7007) and .94 (.8134-.9932) when compared to formal US. The modified Tokyo guidelines for suspicion of AC had a sensitivity of .2 (.0252-.5561) and specificity of .88 (.8173-.931) compared to the final diagnosis. Conclusion: Point-of-care ultrasound was not a better screening test than the modified Tokyo guidelines. We recommend a simplified screening approach for AC using clinical findings and laboratory data, followed by confirmatory formal imaging. This strategy could prevent unnecessary delays in surgical management and use of physician resources.
