OBJECTIVE: Cysteine protease caspase-1 (Casp1) plays a crucial role in the conversion of pro-cytokines to active cytokines (CYTs). The purpose of this work was to determine Casp1 blood levels in a cohort of 114 cholecystectomy patients and assess their association with other CYTs and numeric rating scale (NRS) pain scores, postoperatively.
METHODS: Blood levels of Casp1 and seven CYTs (IL-18, IL-18BP, IL-1ra, IL-6, IL-10, IL-1β, and IL-8) were measured at three time points; before operation, immediately after operation, and six hours after operation in 114 patients with cholelithiasis (Chole).
RESULTS: Casp1 blood levels correlated with NRS pain scores at 24 h following surgery (p=0.016). In addition, Casp1 blood levels correlated significantly to IL-18 blood levels (p<0.001).
CONCLUSIONS: This is the first report to evaluate Casp1 blood levels in Chole patients in correlation with other CYTs. The findings confirm a significant correlation between Casp1 blood levels and NRS pain scores. Moreover, this study provides initial evidence suggesting that inhibition of the activity of Casp1 may reduce postsurgical acute phase immune response possibly through the Casp1/pro-Il-18 pathway.

BACKGROUND: Enteric fever is caused by Salmonella enterica serovars Typhi (S. Typhi) and Paratyphi A, B, and C. It continues to be a significant cause of morbidity and mortality worldwide. In highly endemic areas, children are disproportionately affected, and antimicrobial resistance reduces therapeutic options. It is estimated that 2-5% of enteric fever patients develop chronic asymptomatic infection. These carriers may act as reservoirs of infection; therefore, the prospective identification and treatment of carriers are critical for long-term disease control. We aimed to find the frequency of Salmonella Typhi carriers in patients undergoing cholecystectomy. We also compared the detection limit of culturing versus qPCR in detecting S. Typhi, performed a geospatial analysis of the carriers identified using this study, and evaluated the accuracy of anti-Vi and anti-YncE in identifying chronic typhoid carriage.
METHODS: We performed a cross-sectional study in two centers in Pakistan. Gallbladder specimens were subjected to quantitative PCR (qPCR) and serum samples were analyzed for IgG against YncE and Vi by ELISA. We also mapped the residential location of those with a positive qPCR result.
RESULTS: Out of 988 participants, 3.4% had qPCR-positive gallbladder samples (23 S. Typhi and 11 S. Paratyphi). Gallstones were more likely to be qPCR positive than bile and gallbladder tissue. Anti-Vi and YncE were significantly correlated (r = 0.78 p<0.0001) and elevated among carriers as compared to qPCR negative controls, except for anti-Vi response in Paratyphi A. But the discriminatory values of these antigens in identifying carriers from qPCR negative controls were low.
CONCLUSIONS: The high prevalence of typhoid carriers observed in this study suggests that further studies are required to gain information that will help in controlling future typhoid outbreaks in a superior manner than they are currently being managed.

UNASSIGNED: Cholecystectomy with or without intraoperative cholangiogram (IOC) is an accepted treatment for cholelithiasis. Up to 11.6 % of cholecystectomies have incidental common bile duct (CBD) stones on IOC and 25.3 % of undiagnosed CBD stones will develop life-threatening complications. These will require additional intervention after primary cholecystectomy, further straining the healthcare system. We seek to examine the role of IOC in patients with normal LFTs by evaluating its predictive values, intending to treat undiagnosed CBD stones and therefore ameliorate these issues.
UNASSIGNED: All patients who underwent cholecystectomies with normal LFTs from October 2019 to December 2020 were prospectively enrolled. IOC was done, ERCPs were performed for filling defects and documented as \"true positive\" if ERCP was congruent with the IOC. \"False positives\" were recorded if ERCP was negative. \"True negative\" was assigned to normal IOC and LFT after 2 weeks of follow-up. Those with abnormal LFTs were subjected to ERCP and documented as \"false negative\". Sensitivity, specificity, and predictive values were calculated.
UNASSIGNED: A total of 180 patients were analysed. IOC showed a specificity of 85.5 % and a NPV of 88.1 % with an AUC of 73.7 %. The positive predictive value and sensitivity were 56.5 and 61.9 % respectively.
UNASSIGNED: Routine IOC is a specific diagnostic tool with good negative predictive value. It is useful to exclude the presence of CBD stones when LFT is normal. It does not significantly prolong the length of hospitalization or duration of the cholecystectomy hence reducing the incidence of undetected retained stones and preventing its complications effectively.

BACKGROUND: In acute obstructive common bile duct (CBD) stones endoscopic retrograde cholangiography for CBD stone removal before cholecystectomy (ChE) (\'ERC-first\') is the gold standard of treatment. Intraoperative antegrade balloon dilatation of the duodenal papilla during ChE with flushing of CBD stones to the duodenum (\'ABD-during-ChE\') may be an alternative \'one-stop-shop\' treatment option. However, a comparison of outcomes of the \'ABD-during-ChE\' technique and the\'ERC-first\' approach has never been performed.
METHODS: Retrospective case control matched study of patients suffering from obstructive CBD stones (< 8 mm) without severe pancreatitis or cholangitis that underwent the traditional \'ERC-first\' approach versus the \'ABD-during-ChE\' technique. Primary endpoint was the overall Comprehensive Complication Index (CCI®) from diagnosis to complete CBD stone removal and performed ChE.
RESULTS: A total of 70 patients were included (35 patients each in the \'ERC first\'- and \'ABD-during-ChE\'-group). There were no statistical significant differences in terms of demographics and disease specific characteristics between the two study groups. However, there was a not significant difference towards an increased overall CCI® in the \'ERC-first\' group versus the \'ABD-during-ChE\' group (14.4 ± 15.4 versus 9.8 ± 11.1, p = 0.225). Of note, six major complications (Clavien-Dindo classification ≥ IIIa) occurred in the \'ERC-first\' group versus two in the \'ABD-during-ChE\' group (17% versus 6%, p = 0.136). In addition, significantly more interventions and a longer overall time from diagnosis to complete clearance of bile ducts and performed ChE was found, when comparing the \'ERC-first\' group and the \'ABD-during-ChE\' group (3.7 ± 0.8 versus 1.1 ± 0.4, p < 0.001; 160.5 ± 228.6 days versus 12.0 ± 18.0 days, p < 0.001).
CONCLUSIONS: In patients suffering from acute obstructive CBD stones smaller than 8 mm, compared to the \'ERC-first\' approach, the \'ABD-during-ChE\' technique resulted in significantly less interventions and reduced overall treatment time from diagnosis to complete clearance of bile ducts and performed ChE. This comes together with a strong trend of less intervention related complications in the \'ABD-during-ChE\' group.

OBJECTIVE: The aim of this study is to evaluate the effect of erector spinae plane block (ESPB) as a rescue therapy in the recovery room.
METHODS: This single-center historical cohort study included patients who received either ESPB or intravenous meperidine for pain management in the recovery room. Patients\' numeric rating scale (NRS) scores and opoid consumptions were evaluated.
RESULTS: One hundred and eight patients were included in the statistical analysis. Sixty-two (57%) patients received ESPB postoperatively (pESPB) and 46 (43%) patients were managed with IV meperidine boluses only (IV). The cumulative meperidine doses administered were 0 (0-40) and 30 (10-80) mg for the pESPB and IV groups, respectively (p < 0.001). NRS scores of group pESPB were significantly lower than those of Group IV on T30 and T60.
CONCLUSIONS: ESPB reduces the frequency of opioid administration and the amount of opioids administered in the early post-operative period. When post-operative rescue therapy is required, it should be considered before opioids.
OBJECTIVE: Evaluar el efecto del bloqueo del plano erector espinal (ESPB) como terapia de rescate en la sala de recuperación.
UNASSIGNED: Este estudio de cohortes histórico de un solo centro incluyó a pacientes que recibieron ESPB o meperidina intravenosa para el tratamiento del dolor en la sala de recuperación. Se evaluaron las puntuaciones de la escala de calificación numérica (NRS) de los pacientes y los consumos de opiáceos.
RESULTS: En el análisis estadístico se incluyeron 108 pacientes. Recibieron ESPB 62 (57%) pacientes y los otros 46 (43%) fueron manejados solo con bolos de meperidina intravenosa. Las dosis acumuladas de meperidina administradas fueron 0 (0-40) y 30 (10-80) mg para los grupos de ESPB y de meperidina sola, respectivamente (p < 0.001). Las puntuaciones de dolor del grupo ESPB fueron significativamente más bajas que las del grupo de meperidina sola en T30 y T60.
CONCLUSIONS: El ESPB reduce la frecuencia de administración de opiáceos y la cantidad de estos administrada en el posoperatorio temprano. Cuando se requiera terapia de rescate posoperatoria, se debe considerar antes que los opiáceos.

BACKGROUND: Data on the incidence and clinical relevance of gallstones in patients with suspected acute alcoholic pancreatitis are lacking and are essential to minimize the risk of recurrent acute pancreatitis. The aim of this study was to assess the incidence of gallstones and the associated rate of recurrent acute pancreatitis in patients with presumed acute alcoholic pancreatitis.
METHODS: Between 2008 and 2019, 23 hospitals prospectively enrolled patients with acute pancreatitis. Those diagnosed with their first episode of presumed acute alcoholic pancreatitis were included in this study. The term gallstones was used to describe the presence of cholelithiasis or biliary sludge found during imaging. The primary outcome was pancreatitis recurrence during 3 years of follow-up.
RESULTS: A total of 334 patients were eligible for inclusion, of whom 316 were included in the follow-up analysis. Gallstone evaluation, either during the index admission or during follow-up, was performed for 306 of 334 patients (91.6%). Gallstones were detected in 54 patients (17.6%), with a median time to detection of 6 (interquartile range 0-42) weeks. During follow-up, recurrent acute pancreatitis occurred in 121 of 316 patients (38.3%), with a significantly higher incidence rate for patients with gallstones compared with patients without gallstones (59% versus 34.2% respectively; P < 0.001), while more patients with gallstones had stopped drinking alcohol at the time of their first recurrence (41% versus 24% respectively; P = 0.020). Cholecystectomy was performed for 19 patients with gallstones (36%). The recurrence rate was lower for patients in the cholecystectomy group compared with patients who did receive inadequate treatment or no treatment (5/19 versus 19/34 respectively; P = 0.038).
CONCLUSIONS: Gallstones were found in almost one in every five patients diagnosed with acute alcoholic pancreatitis. Gallstones were associated with a higher rate of recurrent pancreatitis, while undergoing cholecystectomy was associated with a reduction in this rate.

BACKGROUND: The prevalence of neoplastic polyps in gallbladder polyps (GPs) increases sharply with age and is associated with gallbladder carcinoma (GBC). This study aims to predict neoplastic polyps and provide appropriate treatment strategies based on preoperative ultrasound features in patients with different age level.
METHODS: According to the age classification of WHO, 1523 patients with GPs who underwent cholecystectomy from January 2015 to December 2019 at 11 tertiary hospitals in China were divided into young adults group (n=622), middle-aged group (n=665) and elderly group (n=236). Linear scoring models were established based on independent risk variables screened by the Logistic regression model in different age groups. The area under ROC (AUC) to evaluate the predictive ability of linear scoring models, long- and short- diameter of GPs.
RESULTS: Independent risk factors for neoplastic polyps included the number of polyps, polyp size (long diameter), and fundus in the young adults and elderly groups, while the number of polyps, polyp size (long diameter), and polyp size (short diameter) in the middle-aged groups. In different age groups, the AUCs of its linear scoring model were higher than the AUCs of the long- and short- diameter of GPs for differentiating neoplastic and non-neoplastic polyps (all P<0.05), and Hosmer-Lemeshow goodness of fit test showed that the prediction accuracy of the linear scoring models was higher than the long- and short- diameter of GPs (all P>0.05).
CONCLUSIONS: The linear scoring models of the young adults, middle-aged and elderly groups can effectively distinguish neoplastic polyps from non-neoplastic polyps based on preoperative ultrasound features.

OBJECTIVE: There are no studies assessing the long-term quality of life (QoL) following three-dimensional laparoscopy cholecystectomy (3D-LC) in patients with cholelithiasis (Chole).
METHODS: A cohort of 200 patients with Chole were randomized into 3D-LC or minilaparotomy cholecystectomy (MC) groups. RAND-36 survey was performed before randomization, four weeks and five years postoperatively.
RESULTS: Similar postoperative five years RAND-36 scores were reported in the 3D-LC and MC groups. The MC and 3D-LC groups combined analysis, social functioning (SF, p=0.007), mental health (MH, p=0.001), role physical (RP, p<0.001) and bodily pain (BP, p<0.001) domains increased significantly. In comparison to the Finnish reference RAND-36 (FRR) scores, the scores at five years increased significantly in the MH domain, while four RAND-36 domains; Physical functioning (PF), general health (GH), RP, BP remained significantly lower in comparison to the FRR scores.
CONCLUSIONS: A relatively similar long-term outcome in the 3D-LC and MC patients is shown. Interestingly, five RAND-36 domains increased during five years follow-up, while four RAND-36 domains remained lower than FRR scores, which may indicate onset of possible new symptoms following cholecystectomy in long-term follow-up.

UNASSIGNED: During the Sars-Cov-2 crisis, some of the resources committed to emergency surgery services were transiently reallocated to the care of patients with severe COVID-19, preserving immediate treatment of mostly non-deferrable conditions. Moreover, the fear of contracting infections or hindering the treatment of critical COVID-19 patients has caused many individuals to defer seeking emergency care. This situation has then possibly modified the standard of care of some common surgical conditions and the relative outcomes. Our aims was to highlight any difference in surgical outcomes in patients treated for acute cholecystitis before and during the COVID-19 outbreak.
UNASSIGNED: This is a retrospective study on a prospectively collected database that included all consecutive patients treated for acute cholecystitis from March 2019 to February 2021 at the Lugano Regional Hospital, a COVID-free hospital for general surgery patients. Patients were divided into pre-and post-COVID-19 outbreak groups. We collected thorough clinical characteristics and intra-and postoperative outcomes.
UNASSIGNED: We included 124 patients, of which 60 and 64 were operated on before and after the COVID-19 outbreak respectively. The two groups resulted similar in terms of patients\' clinical characteristics (age, gender, body mass index, ASA score, and comorbidities). Patients in the post-outbreak period were admitted to the hospital 0.7 days later than patients in the pre-outbreak period (3.8 ± 6.0 days vs. 3.1 ± 4.1 days, p = 0.453). Operative time, recovery room time, complications, and reoperations resulted similar between groups. More patients in the post-outbreak period received postoperative antibiotic therapy (63.3% vs. 37.5%, p = 0.004) and for a longer time (6.9 ± 5.1 days vs. 4.5 ± 3.9 days, p = 0.020). No significant histopathological difference was found in operatory specimens.
UNASSIGNED: Despite more frequent antibiotic therapy that suggests eventually worse inflammatory local status, our results showed similar outcomes for patients treated for acute cholecystitis before and during the COVID-19 pandemic. The local COVID management, reallocating resources, and keeping COVID-free hospitals was key to offering patients a high standard of treatment.

BACKGROUND: Treatment and follow-up strategies for silent gallbladder stones in patients before kidney transplantation (KT) remain unknown. Therefore, the authors aimed to elucidate the role of pre-KT cholecystectomy in preventing biliary and surgical complications.
METHODS: This study retrospectively analyzed 2295 KT recipients and 3443 patients waiting for KT at a single tertiary center from January 2005 to July 2022. The primary outcomes were the incidences of biliary and postcholecystectomy complications in KT recipients. Firth\'s logistic regression model was used to assess the risk factors for biliary complications.
RESULTS: Overall, 543 patients awaiting KT and 230 KT recipients were found to have biliary stones. Among the KT recipients, 16 (7%) underwent cholecystectomy before KT, while others chose to observe their biliary stones. Pre-KT cholecystectomy patients did not experience any biliary complications, and 20 (9.3%) patients who chose to observe their stones experienced complications. Those who underwent cholecystectomy before KT developed fewer postcholecystectomy complications (6.3%) compared with those who underwent cholecystectomy after KT (38.8%, P =0.042), including reduced occurrences of fatal postoperative complications based on the Clavien-Dindo classification. Multiple stones [odds ratio (OR), 3.09; 95% CI: 1.07-8.90; P =0.036), thickening of the gallbladder wall (OR, 5.39; 95% CI: 1.65-17.63; P =0.005), and gallstones >1 cm in size (OR 5.12, 95% CI: 1.92-13.69, P =0.001) were independent risk factors for biliary complications. Among patients awaiting KT, 23 (4.2%) underwent cholecystectomy during the follow-up, resulting in one postcholecystectomy complication.
CONCLUSIONS: Gallstone-related biliary complications following KT and subsequent cholecystectomy was associated with more serious complications and worse treatment outcomes. Therefore, when KT candidates had risk factor for biliary complications, pre-emptive cholecystectomy for asymptomatic cholecystolithiasis could be considered to reduce further surgical risk.
