Laparoscopic vs open approach for acute cholecystitis in octogenarians. A prospective multicenter observational nationwide study

BACKGROUND

The world population is aging, with octogenarians expected to reach over 400 million by 2050. Acute cholecystitis is a serious complication in the elderly. Age is not a contraindication for emergency cholecystectomy, an option that can both save lives and preserve quality of life.

METHODS

The present study aimed to compare open and laparoscopic surgical approaches. Over six months, 38 emergency surgery units enrolled all consecutive octogenarians with acute cholecystitis undergoing cholecystectomy. Postoperative outcomes were compared after propensity score matching analysis.

RESULTS

The study included 212 patients (84 years [81-86], 47.2% women). The open approach was used in 32.1% of patients, and the laparoscopic approach in 67.9%. After propensity score matching, a decrease in hospital stays (open, 8 days [6-13]; laparoscopic, 5 days [4-8]; P < .001), 30-day morbidity (open, 48.5%; laparoscopic, 26.5%; P = .01), and 30-day mortality (open, 13.2%, laparoscopic, 1.5%; P = .02) was found. Among the specific postoperative complications, a decrease in septicemia (open, 14.7%; laparoscopic, 0%; P = .001) was observed.

CONCLUSIONS

Laparoscopic approach was used in two out of three octogenarians. After propensity score matching, octogenarians undergoing laparoscopic approach had shorter length of hospital stay, fewer 30-day postoperative complications, fewer episodes of septicemia, and less 30-day mortality than octogenarians undergoing open approach. These findings suggest that the laparoscopic approach may be the preferred choice for octogenarians with acute cholecystitis undergoing cholecystectomy.

Updates on Antibiotic Regimens in Acute Cholecystitis

Acute cholecystitis is one of the most common surgical diseases, which may progress from mild to severe cases. When combined with bacteremia, the mortality rate of acute cholecystitis reaches up to 10-20%. The standard of care in patients with acute cholecystitis is early laparoscopic cholecystectomy. Percutaneous cholecystostomy or endoscopic procedures are alternative treatments in selective cases. Nevertheless, antibiotic therapy plays a key role in preventing surgical complications and limiting the systemic inflammatory response, especially in patients with moderate to severe cholecystitis. Patients with acute cholecystitis have a bile bacterial colonization rate of 35-60%. The most frequently isolated microorganisms are Escherichia coli, Klebsiella spp., Streptococcus spp., Enterococcus spp., and Clostridium spp. Early empirical antimicrobial therapy along with source control of infection is the cornerstone for a successful treatment. In these cases, the choice of antibiotic must be made considering some factors (e.g., the severity of the clinical manifestations, the onset of the infection if acquired in hospital or in the community, the penetration of the drug into the bile, and any drug resistance). Furthermore, therapy must be modified based on bile cultures in cases of severe cholecystitis. Antibiotic stewardship is the key to the correct management of bile-related infections. It is necessary to be aware of the appropriate therapeutic scheme and its precise duration. The appropriate use of antibiotic agents is crucial and should be integrated into good clinical practice and standards of care.

Efficacy of early laparoscopic cholecystectomy compared with percutaneous transhepatic gallbladder drainage in treating acute calculous cholecystitis in elderly patients

BACKGROUND

Acute calculous cholecystitis is a common acute disease in elderly patients. This study aimed to evaluate the efficacy of early laparoscopic cholecystectomy (ELC) compared to percutaneous transhepatic gallbladder drainage (PTGD) for treating acute calculous cholecystitis in elderly patients.

METHODS

This retrospective study compared the clinical outcomes of two groups of elderly patients treated with ELC (group A) and PTGD (group B) from January 2018 to December 2021. Preoperative clinical characteristics and postoperative treatment outcomes were analyzed for both groups.

RESULTS

There were no statistically significant differences in preoperative clinical characteristics between the ELC and PTGD groups. ELC took longer to perform (69.8 ± 15.9 min vs. 29.6 ± 5.3 min, p < 0.001) but resulted in a significantly shorter duration of pain (1.9 ± 0.9 days vs. 3.9 ± 1.0 days, p < 0.001) and hospital stay (6.3 ± 2.5 days vs. 9.9 ± 3.6 days, p < 0.001), and a lower rate of sepsis (3.4% vs. 16.9%, p < 0.019). Time to soft diet was faster in the ELC group (1.5 ± 0.9 days vs. 3.0 ± 1.6 days, p < 0.001). Fewer patients in the ELC group experienced surgical reintervention than in the PTGD group (0% vs. 5.6%, p = 0.043). The incidence of postoperative complications and readmission rates in the ELC group were significantly lower than those in the PTGD group (ELC, 3.6%; PTGD, 25.4%, p = 0.001).

CONCLUSIONS

ELC is an effective treatment option for acute calculous cholecystitis in elderly patients, and has the added benefits of low postoperative complication rates, rapid recovery, shorter duration of pain, and excellent curative effects as compared to PTGD.

The Diagnosis and Treatment of Acute Cholecystitis: A Comprehensive Narrative Review for a Practical Approach

Acute cholecystitis (AC), generally associated with the presence of gallstones, is a relatively frequent disease that can lead to serious complications. For these reasons, AC warrants prompt clinical diagnosis and management. There is general agreement in terms of considering early laparoscopic cholecystectomy (ELC) to be the best treatment for AC. The optimal timeframe to perform ELC is within 72 h from diagnosis, with a possible extension of up to 7-10 days from symptom onset. In the first hours or days after hospital admission, before an ELC procedure, the patient's medical management comprises fasting, intravenous fluid infusion, antimicrobial therapy, and possible administration of analgesics. Additionally, concomitant conditions such as choledocholithiasis, cholangitis, biliary pancreatitis, or systemic complications must be recognized and adequately treated. The importance of ELC is related to the frequent recurrence of symptoms and complications of gallstone disease in the interval period between the onset of AC and surgical intervention. In patients who are not eligible for ELC, it is suggested to delay surgery at least 6 weeks after the clinical presentation. Critically ill patients, who are unfit for surgery, may require rescue treatments, such as percutaneous or endoscopic gallbladder drainage (GBD). A particular treatment approach should be applied to special populations such as pregnant women, cirrhotic, and elderly patients. In this review, we provide a practical diagnostic and therapeutic approach to AC, even in specific clinical situations, based on evidence from the literature.

Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients: the Italian Society of Emergency Surgery and Trauma (SICUT) guidelines

Dealing with acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients is frequent during daily practice and requires complex management. Several procedures exist to postpone and/or prevent surgical intervention in those patients who temporarily or definitively cannot undergo surgery. After a systematic review of the literature, an expert panel from the Italian Society of Emergency Surgery and Trauma (SICUT) discussed the different issues and statements in subsequent rounds. The final version of the statements was discussed during the annual meeting in Rome (September 2022). The present paper presents the definitive conclusions of the discussion. Fifteen statements based on the literature evidence were provided. The statements gave precise indications regarding the decisional process and the management of patients who cannot temporarily or definitively undergo cholecystectomy for acute cholecystitis. Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients should be multidisciplinary. The different gallbladder drainage methods must be tailored according to each patient and based on the expertise of the hospital. Percutaneous gallbladder drainage is recommended as the first choice as a bridge to surgery or in severely physiologically deranged patients. Endoscopic gallbladder drainage (cholecystoduodenostomy and cholecystogastrostomy) is suggested as a second-line alternative especially as a definitive procedure for those patients not amenable to surgical management. Trans-papillary gallbladder drainage is the last option to be reserved only to those unfit for other techniques. Delayed laparoscopic cholecystectomy in patients with percutaneous gallbladder drainage is suggested in all those patients recovering from the conditions that previously discouraged surgical intervention after at least 6 weeks from the gallbladder drainage.

Percutaneous cholecystostomy in elderly patients with acute cholecystitis: a systematic review and meta-analysis

Percutaneous cholecystostomy (PC) is often preferred over early cholecystectomy (EC) for elderly patients presenting with acute cholecystitis (AC). However, there is a lack of solid data on this issue. Following the PRISMA guidelines, we searched the Medline and Web of Science databases for reports published before December 2022. Studies that assessed elderly patients (aged 65 years and older) with AC treated using PC, in comparison with those treated with EC, were included. Outcomes analyzed were perioperative outcomes and readmissions. The literature search yielded 3279 records, from which 7 papers (1208 patients) met the inclusion criteria. No clinical trials were identified. Patients undergoing PC comprised a higher percentage of cases with ASA III or IV status (OR 3.49, 95%CI 1.59-7.69, p = 0.009) and individuals with moderate to severe AC (OR 1.78, 95%CI 1.00-3.16, p = 0.05). No significant differences were observed in terms of mortality and morbidity. However, patients in the PC groups exhibited a higher rate of readmissions (OR 3.77, 95%CI 2.35-6.05, p < 0.001) and a greater incidence of persistent or recurrent gallstone disease (OR 12.60, 95%CI 3.09-51.38, p < 0.001). Elderly patients selected for PC, displayed greater frailty and more severe AC, but did not exhibit increased post-interventional morbidity and mortality compared to those undergoing EC. Despite their inferior life expectancy, they still presented a greater likelihood of persistent or recurrent disease compared to the control group.

Outcomes after laparoscopic cholecystectomy in patients older than 80 years: two-years follow-up

BACKGROUND

The laparoscopic cholecystectomy is the treatment of choice for patients with benign biliary disease. It is necessary to evaluate survival after laparoscopic cholecystectomy in patients over 80 years old to determine whether the long-term mortality rate is higher than the reported recurrence rate. If so, this age group could benefit from a more conservative approach, such as antibiotic treatment or cholecystostomy. Therefore, the aim of this study was to evaluate the factors associated with 2 years survival after laparoscopic cholecystectomy in patients over 80 years old.

METHODS

We conducted a retrospective observational cohort study. We included all patients over 80 years old who underwent laparoscopic cholecystectomy. Survival analysis was conducted using the Kaplan‒Meier method. Cox regression analysis was implemented to determine potential factors associated with mortality at 24 months.

RESULTS

A total of 144 patients were included in the study, of whom 37 (25.69%) died at the two-year follow-up. Survival curves were compared for different ASA groups, showing a higher proportion of survivors at two years among patients classified as ASA 1-2 at 87.50% compared to ASA 3-4 at 63.75% (p = 0.001). An ASA score of 3-4 was identified as a statistically significant factor associated with mortality, indicating a higher risk (HR: 2.71, CI95%:1.20-6.14).

CONCLUSIONS

ASA 3-4 patients may benefit from conservative management due to their higher risk of mortality at 2 years and a lower probability of disease recurrence.

[Experience of indocyanine green use in acute calculous cholecystitis]

OBJECTIVE

To assess the safety and effectiveness of the indocyanine green use in acute cholecystitis for identification of anatomical variants of the biliary tree; prevention and timely detection of intraoperative complications.

MATERIAL AND METHODS

The medication of indocyanine green made by OOO «Ferment» domestic manufacturer was used. The drug dose from 2.5 mg to 10 mg was applied according to studied materials (8). Time of the surgery beginning was from 2 to 6 hours after intravenous injection of aqueous solution, respectively. In addition, it has been established that the optimal drug dose is 5 mg. The surgery should be performed not earlier than 3 hours after, but no later than 6 hours. This allows to achieve the most comfortable fluorescence of the extrahepatic biliary tract. The drug concentration in the liver cells decreases by this time and increases in the biliary tract. It is not always possible to perform the operation strictly within the specified time limit considering the urgency of the surgical intervention. In this connection, the surgery was carried out not earlier than 3 hours after the drug injection, but not later than 6 hours. Endoscopic equipment with the ability to display near-infrared fluorescence was used. A laser light source with a wavelength of 820 nm in the Arthrex imaging system with 4K resolution as well as the Olympus imaging system with HD resolution were used for fluorescence excitation.

RESULTS

The implementation of intraoperative fluorescent navigation with indocyanine green contributes to the improvement of safety and effectiveness of surgical treatment through visualization of topography and identification of anatomical variants of the biliary tree; possibilities of prevention and timely detection of intraoperative complications. The use of indocyanine green allows to intraoperatively reveal atypical location and different variations of the extrahepatic biliary tract.

Serial Measurements of Serum Glial Fibrillary Acidic Protein in Moderate-Severe Traumatic Brain Injury: Potential Utility in Providing Insights into Secondary Insults and Long-Term Outcome

In patients with traumatic brain injury (TBI), serum biomarkers may have utility in assessing the evolution of secondary brain injury. A panel of nine brain-injury- associated biomarkers was measured in archived serum samples over 10 days post-injury from 100 patients with moderate-severe TBI. Among the biomarkers evaluated, serum glial fibrillary acidic protein (GFAP) had the strongest associations with summary measures of acute pathophysiology, including intracranial pressure (ICP), cerebral perfusion pressure (CPP), and brain tissue pO2 (PbtO2). Group based trajectory (TRAJ) analysis was used to identify three distinct GFAP subgroups. The low TRAJ group (n = 23) had peak levels of 9.4 + 1.2 ng/mL that declined rapidly. The middle TRAJ group (n = 48) had higher peak values (31.5 + 5.0 ng/mL) and a slower decline over time. The high TRAJ group (n = 26) had very high, sustained peak values (59.6 + 12.5 ng/mL) that even rose among some patients over 10 days. Patients in the high TRAJ group had significantly higher mortality rate than patients in low and middle TRAJ groups (26.9% vs. 7.0%, p = 0.028). The frequency of poor neurological outcome (Glasgow Outcome Score Extended [GOS-E] 1-4) was 88.5% in the high TRAJ group, 54.2% in the middle TRAJ group, and 30.4% in the low TRAJ group (p < 0.001). ICP was highest in the high TRAJ group (median 17.6 mm Hg), compared with 14.4 mmHg in the low and 15.9 mm Hg in middle TRAJ groups (p = 0.002). High TRAJ patients spent the longest time with ICP >25 mm Hg, median 23 h, compared with 2 and 6 h in the low and middle TRAJ groups (p = 0.006), and the longest time with ICP >30 mm Hg, median 5 h, compared with 0 and 1 h in the low and middle TRAJ groups, respectively (p = 0.013). High TRAJ group patients more commonly required tier 2 or 3 treatment to control ICP. The high TRAJ group had the longest duration when CPP was <50 mm Hg (p = 0.007), and PbtO2 was <10 mm Hg (p = 0.002). Logistical regression was used to study the relationship between temporal serum GFAP patterns and 6-month GOS-E. Here, the low and middle TRAJ groups were combined to form a low-risk group, and the high TRAJ group was designated the high-risk group. High TRAJ group patients had a greater chance of a poor 6-month GOS-E (p < 0.0001). When adjusting for baseline injury characteristics, GFAP TRAJ group membership remained associated with GOS-E (p = 0.003). When an intensive care unit (ICU) injury burden score, developed to quantify physiological derangements, was added to the model, GFAP TRAJ group membership remained associated with GOS-E (p = 0.014). Mediation analysis suggested that ICU burden scores were in the causal pathway between TRAJ group and 6-month mortality or GOS-E. Our results suggest that GFAP may be useful to monitor serially in moderate-severe TBI patients. Future studies in larger cohorts are needed to confirm these results.

The value of preoperative neutrophil/lymphocyte ratio in predicting the severity of cholecystolithiasis with cholecystitis in elderly patients

BACKGROUND

This study aims to assess the effectiveness of neutrophil/lymphocyte ratio (NLR) and C-reactive protein (CRP) in diagnosing cholecystolithiasis with cholecystitis in elderly patients. Additionally, the study seeks to determine the predictive value of preoperative NLR in determining the severity of the condition in this population.

METHODS

This study is a retrospective cohort study, including 160 elderly patients with cholecystolithiasis with cholecystitis (45 cases of simple cholecystitis, 58 cases of suppurative cholecystitis, 57 cases of gangrenous cholecystitis) and 60 cases of normal gallbladder histology. The study collected clinical data of the patients detected the preoperative CRP content, neutrophil, and lymphocyte levels through blood routine tests, and calculated the NLR value. The diagnostic value of NLR and CRP was determined by using the Receiver Operating Characteristic Curve (ROC), and the optimal value of preoperative NLR related to the severity of elderly patients with cholecystolithiasis with cholecystitis was identified.

RESULTS

This study found that for elderly patients with cholecystolithiasis with cholecystitis, preoperative NLR and CRP levels can be used to distinguish the condition. The critical value for NLR was found to be 2.995 (95% CI, 0.9465-0.9853; P < 0.001) with an area under the ROC curve of 0.9659, while the critical value for CRP was 13.05 (95% CI, 0.9284-0.9830; P < 0.001) with an area under the ROC curve of 0.9557. Both NLR and CRP were found to have equivalent diagnostic abilities. Additionally, the study found that there were significant differences in neutrophil and lymphocyte levels in elderly patients with different severity levels, with NLR increasing as severity increased (P < 0.001). The study identified cut-off values for preoperative NLR that could distinguish Simple cholecystitis and Purulent cholecystitis, as well as Purulent cholecystitis and Gangrenous cholecystitis in elderly patients with cholecystolithiasis, with respective AUCs of 0.8441 (95% CI: 0.7642-0.9239; P < 0.001) and 0.7886(95% CI: 0.7050-0.8721, P < 0.001), sensitivities of 91.38% and 87.72%, and specificities of 73.33% and 63.79%.

CONCLUSIONS

Preoperative NLR and CRP values can serve as indicators to detect cholecystolithiasis with cholecystitis in elderly patients. Additionally, NLR has been recognized as a potential tool to differentiate the severity of cholecystolithiasis with cholecystitis in the elderly population.

Efficacy of blood parameters as indicators of the need for overdue urgent cholecystectomy in elderly patients with acute cholecystitis

BACKGROUND

Although early cholecystectomy is recommended for patients with acute cholecystitis, conservative treatment followed by delayed cholecystectomy (DC) is a highly preferred modality, especially in older adult patients. However, some severe cases require overdue urgent cholecystectomy (OC). This study aimed to evaluate the ability of laboratory findings and Tokyo severity classification (TokyoSC) to differentiate those with the need for OC among elderly patients.

METHODS

Laboratory/radiological/clinical findings of geriatric patients with acute cholecystitis on admission and TokyoSC were retrospectively analyzed. The DC and OC groups were compared.

RESULTS

The mean age of the 164 patients was 72.3±6.4 years. White blood cell, neutrophil (NEU), immature granulocyte (IG), C-reactive protein, neutrophil-to-lymphocyte ratio (NLR), and TokyoSC parameters were all significant at P<0.001 in differentiation. NLR had a specificity of 98%, and TokyoSC had a sensitivity of 98%.

CONCLUSION

NLR, NEU, IG, and TokyoSC were effective in differentiating patients who needed OC while planning conservative treatment + DC for older adult patients who were followed up due to acute cholecystitis. If the NLR is >9.9 and TokyoSC is moderate/high, early cholecystectomy should be preferred instead of conservative treatment + DC in aged patients.

Prophylactic cholecystectomy offers best outcomes following ERCP clearance of common bile duct stones: a meta-analysis

BACKGROUND

Symptomatic calculus biliary disease is common with associated morbidity and occasional mortality, further confounded when there is concomitant common bile duct (CBD) stones. Choledocholithiasis and clearance of the duct reduces recurrent cholangitis, but the question is whether after clearance of the CBD if there is a need to perform a cholecystectomy. This meta-analysis evaluated outcomes in patients undergoing ERCP with or without sphincterotomy to determine if cholecystectomy post-ERCP clearance offers optimal outcomes over a wait-and-see approach.

METHODS

A Prospero registered meta-analysis of the literature using PRISMA guidelines incorporating articles related to ERCP, choledocholithiasis, cholangitis and cholecystectomy was undertaken for papers published between 1st January 1991 and 31st May 2021. Existing research that demonstrates outcomes of ERCP with no cholecystectomy versus ERCP and cholecystectomy was reviewed to determine the related key events, complications and mortality of leaving the gallbladder in situ and removing it. Odds ratios (OR) were calculated using Review Manager Version 5.4 and meta-analyses performed using OR using fixed-effect (or random-effect) models, depending on the heterogeneity of studies.

RESULTS

13 studies (n = 2598), published between 2002 and 2019, were included in this meta-analysis, 6 retrospective, 2 propensity score-matched retrospective studies, 3 prospective studies and 2 randomised control trials from a total of 11 countries. There were 1433 in the no cholecystectomy cohort (55.2%) and 1165 in the prophylactic cholecystectomy (44.8%) cohort. Cholecystectomy resulted in a decreased risk of cholecystitis (OR = 0.15; CI 0.07-0.36; p < 0.0001), cholangitis (OR = 0.51; CI 0.26-1.00; p = 0.05) and mortality (OR = 0.38; CI 0.16-0.9; p = 0.03). In addition, prophylactic cholecystectomy resulted in a significant reduction in biliary events, biliary pain and pancreatitis.

CONCLUSIONS

In patients undergoing CBD clearance, consideration should be given to performing prophylactic cholecystectomy to optimise outcomes.

Early laparoscopic cholecystectomy for acute cholecystitis: Does age matter?

AIM

Advances in laparoscopic surgery and perioperative care have improved the prognosis of operated patients, especially the oldest among them. This study aimed to assess the outcomes of early laparoscopic cholecystectomy for acute calculous cholecystitis in older adult patients.

METHODS

A retrospective analysis was carried out of 567 patients who underwent early laparoscopic cholecystectomy for acute calculous cholecystitis between January 2003 and July 2021. The outcomes of older adult patients (≥ 75 years) were compared with those of younger patients.

RESULTS

The older adult group had significantly more patients with an American Society of Anesthesiologists score ≥3 (37.5% vs 8.3%; P < 0.001) and more severe acute calculous cholecystitis (grade II; 82.8% vs 67%; P = 0.01). There were no significant differences regarding operative time (90 vs 80 min; P = 0.064), conversion rate (20.3% vs 13.5%; P = 0.144), and both intra- and postoperative morbidity, principally bile duct injuries (1.6% vs 0%; P = 0.113) and bile leakage (0% vs 1.2%; P = 1).

CONCLUSION

Early laparoscopic cholecystectomy could be proposed safely for older adult patients with mild and moderate acute cholecystitis. Geriatr Gerontol Int 2023; 23: 671-675.

Factors Affecting Early Cholecystectomy for Acute Cholecystitis in Older People-A Population-Based Study

OBJECTIVES

Acute cholecystitis is one of the most common surgical presentations in Australia and increases with age. Guidelines recommend early laparoscopic cholecystectomy (within 7 days), as it results in shorter length of stay, reduced costs and readmission rates. Despite this, there is a perception that early cholecystectomy may result in higher morbidity and conversion to open surgery in older patients. Our objective is to report the proportion of early versus delayed cholecystectomy in older patients in New South Wales (NSW), Australia, and to compare health outcomes and factors influencing variation.

DESIGN

This is a retrospective population-based cohort study of all cholecystectomies for primary acute cholecystitis in NSW residents aged >50, between 2009 and 2019. The primary outcome was the proportion of early versus delayed cholecystectomy. We used multilevel multivariable logistic regression analyses adjusted for age, sex, comorbidities, insurance status, socio-economic status and hospital characteristics.

RESULTS

A high rate (85%) of the 47,478 cholecystectomies in older patients were performed within 7 days of admission. Delayed surgery was associated with increasing age and comorbidity, male sex, Medicare-only insurance and surgery in low- or medium-volume centres. Early surgery was associated with shorter overall length of stay, fewer readmissions, less conversion to open surgery and lower bile duct injury rates.

CONCLUSION

A high proportion of adults with cholecystitis are undergoing early cholecystectomy in NSW. Our results support the efficacy of early cholecystectomy in older patients and identify potentially modifiable factors relevant to health care professionals and policymakers.

Risk factors for complications in acute calculous cholecystitis. Deconstruction of the Tokyo Guidelines

OBJECTIVE

To challenge the risk factors described in Tokyo Guidelines in Acute Calculous Cholecystitis.

METHODS

Retrospective single center cohort study with 963 patients with Acute Cholecystitis during a period of 5 years. Some 725 patients with a "pure" Acute Calculous Cholecystitis were selected. The analysis included 166 variables encompassing all risk factors described in Tokyo Guidelines. The Propensity Score Matching method selected two subgroups of patients with equal comorbidities, to compare the severe complications rate according to the initial treatment (Surgical vs Non-Surgical). We analyzed the Failure-to-rescue as a quality indicator in the treatment of Acute Calculous Cholecystitis.

RESULTS

the median age was 69 years (IQR 53-80). 85.1% of the patients were ASA II or III. The grade of the Acute Calculous Cholecystitis was mild in a 21%, moderate in 39% and severe in 40% of the patients. Cholecystectomy was performed in 95% of the patients. The overall complications rate was 43% and the mortality was 3.6%. The Logistic Regression model isolated 3 risk factor for severe complication: ASA > II, cancer without metastases and moderate to severe renal disease. The Failure-to-Rescue (8%) was higher in patients with non-surgical treatment (32% vs. 7%; P = 0.002). After Propensity Score Matching, the number of severe complications was similar between Surgical and Non-Surgical treatment groups (48.5% vs 62.5%; P = 0.21).

CONCLUSIONS

the recommended treatment for Acute Calculous Cholecystitis is the Laparoscopic Cholecystectomy. Only three risk factors from the Tokyo Guidelines list appeared as independent predictors of severe complications. The failure-to-rescue is higher in non-surgically treated patients.

A systematic review of perioperative clinical practice guidelines for care of older adults living with frailty

BACKGROUND

Perioperative frailty is prevalent and requires complex management, which could be guided by clinical practice guidelines (CPGs). The objective of this systematic review was to identify and synthesise CPGs that provide perioperative recommendations specific to older adults living with frailty.

METHODS

After protocol registration, we performed a systematic review of CPGs. MEDLINE, Embase, CINAHL, and 14 grey literature databases were searched (January 1, 2000 until December 22, 2021). We included all CPGs that contained at least one frailty-specific recommendation related to any phase of the perioperative period. We compiled all relevant recommendations, extracted underlying strength of evidence, and categorised them by perioperative phase of care. Within each phase, recommendations were synthesised inductively into themes. Quality of CPGs was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument.

RESULTS

From 4707 citations, 13 guidelines were included; 8/13 were focused on the perioperative care of older surgical patients in general. Among 110 recommendations extracted, 37 themes were generated, with the majority pertaining to preoperative care. Four themes were supported by strong evidence: performing preoperative frailty assessments, using multidimensional frailty instruments, reducing urinary catheter use, and following multidisciplinary care and communication throughout the perioperative period. Per AGREE II, most guidelines (8/13; 62%) were recommended for use with modifications.

CONCLUSIONS

Despite increasing numbers of patients living with frailty, few guidelines exist that address frailty-specific perioperative care. Given the lack of strong evidence-based recommendations, particularly outside the preoperative period, high-quality primary research is required to underpin future guidelines and better inform the care of older surgical patients with frailty.

Early laparoscopic cholecystectomy for acute cholecystitis: should we operate beyond the first week?

BACKGROUND

The deadline for early laparoscopic cholecystectomy (ELC) in patients with acute calculous cholecystitis (ACC) is the subject of much debate. The aim of this study was to assess outcomes of ELC in patients with more than 7 days of symptoms.

METHODS

It is a retrospective analysis of 564 patients having undergone ELC for ACC between January 2003 and June 2021. Patients were divided into two groups according to the timing between the onset of symptoms and surgery: group 1 (G1), within the first 7 days of symptoms, and group 2 (G2) after day 7 of symptoms.

RESULTS

Apart from a longer operative time (G1 80 min vs. G2 90 min; p = 0.016), there were no significant differences regarding conversion rate (G1 14.5% vs. G2 13.2%; p = 0.748), both intra- and postoperative complications, mainly bile duct injuries (G1 0.2% vs. G2 0%; p = 1) and bile leakage (G1 1.2% vs. G2 0%; p = 1) and postoperative length of stay (G1 2 days [1-3] vs. G2 2 days [1-4]; p = 0.125).

CONCLUSION

Early laparoscopic cholecystectomy could be proposed for patients with acute calculous cholecystitis even beyond 7 days of symptoms.

Effects of Remote Ischemic Preconditioning on Postoperative Cognitive Dysfunction in Elderly Patients with Laparoscopic Cholecystectomy

Purpose

We hypothesized that remote ischemic preconditioning (RIPC) could improve postoperative cognitive dysfunction (POCD) in elderly patients following laparoscopic cholecystectomy (LC).

Patients and Methods

Eighty-eight patients were randomly assigned to either the control or the RIPC group. The RIPC was applied on the right upper limb using a blood pressure cuff inflating 200 mmHg, consisting of 3 cycles of 5 min ischemia and 5 min reperfusion. Serum concentrations of Neuron-specific Enolase (NSE) and Brain-Derived Neurotrophic Factor (BDNF) were collected at one-day preoperative (T0), at the end of the operation (T4) and one-day postoperative (T5). Z score was tested at T0 and 3 days after the operation (T6). POCD was determined if there were two Z scores ≥1.96 at the same time or an average Z score ≥1.96.

Results

There was no significant difference in the Z score of each test between the two groups at T0 (P > 0.05). Notably, the duration of Stroop test C was significantly shorter in the RIPC group than that in the Control group at T6 (P = 0.01). POCD occurred in 1/44 (2.3%) patients in the RIPC group and 8/44 (18.2%) patients in the control group at T6 (P=0.035). In addition, serum NSE concentration was significantly decreased, but serum BDNF concentration was increased compared with the control group at T4 and T5 (P<0.001).

Conclusion

RIPC could reduce the incidence of POCD in elderly patients after laparoscopic cholecystectomy.

Developing a prediction model for successful aging among the elderly using machine learning algorithms

Objective

The aging phenomenon has an increasing trend worldwide which caused the emergence of the successful aging (SA)1 concept. It is believed that the SA prediction model can increase the quality of life (QoL)2 in the elderly by decreasing physical and mental problems and enhancing their social participation. Most previous studies noted that physical and mental disorders affected the QoL in the elderly but didn't pay much attention to the social factors in this respect. Our study aimed to build a prediction model for SA based on the physical, mental, and specially more social factors affecting SA.

Methods

The 975 cases related to SA and non-SA of the elderly were investigated in this study. We used the univariate analysis to determine the best factors affecting the SA. AB3, XG-Boost J-48, RF4, artificial neural network5, support vector machine6, and NB7 algorithms were used for building the prediction models. To get the best model predicting the SA, we compared them using positive predictive value (PPV)8, negative predictive value (NPV)9, sensitivity, specificity, accuracy, F-measure, and area under the receiver operator characteristics curve (AUC).

Results

Comparing the machine learning10 model's performance showed that the random forest (RF) model with PPV = 90.96%, NPV = 99.21%, sensitivity = 97.48%, specificity = 97.14%, accuracy = 97.05%, F-score = 97.31%, AUC = 0.975 is the best model for predicting the SA.

Conclusions

Using prediction models can increase the QoL in the elderly and consequently reduce the economic cost for people and societies. The RF can be considered an optimal model for predicting SA in the elderly.

Laparoscopic Cholecystectomy in Acute Cholecystitis: Refining the Best Surgical Timing Through Network Meta-Analysis of Randomized Trials

BACKGROUND

Acute cholecystitis (AC) is largely diffused among population worldwide. Laparoscopic cholecystectomy is the treatment of choice. Current evidence suggests a clinical benefit of early cholecystectomy. The aim of the present study was to evaluate the different "timing" ("early" vs. "delayed" cholecystectomy), through the application of network meta-analyses, to define the most adequate interval associated with the best outcomes.

MATERIALS AND METHODS

A network meta-analysis of randomized controlled trials was conducted.

RESULTS

Early cholecystectomy ≤72 hours from symptoms reduced conversion rate in comparison to: cholecystectomy ≤7 days from symptoms ( P =0.044), delayed cholecystectomy within 1 to 5 weeks from first admission ( P =0.010) and 6 to 12 weeks from symptoms resolutions ( P =0.009). Delaying cholecystectomy to 6 to 12 weeks reduces operating time in respect to early cholecystectomy ≤72 hours from symptoms ( P =0.001), within 24 hours from admission ( P =0.001), ≤72 hours from admission ( P =0.001) and ≤7 days from symptoms ( P =0.001). Cholecystectomy ≤24 hours from admission was the best strategy to reduce total in-hospital stay, whereas delaying cholecystectomy to 6 to 12 weeks was the worst strategy. The same applied when cholecystectomy was performed ≤72 hours from symptoms in respect to both delayed strategies ( P =0.001 for both comparisons) or when it was performed ≤72 hours from admission ( P =0.001 for both comparisons). Cholecystectomy ≤72 hours from symptoms onset was the best strategy to reduce postoperative complications, the worst was represented by delayed cholecystectomy at 1 to 5 weeks from first admission.

CONCLUSION

AC should be operated as soon as possible. AC surgical management should be considered in a dynamic time conception to optimize clinical, organizational, and economical outcomes.

Endosonography-Guided Versus Percutaneous Gallbladder Drainage Versus Cholecystectomy in Fragile Patients with Acute Cholecystitis-A High-Volume Center Study

Background and Objectives: Acute cholecystitis is a frequent cause of admission to the emergency department, especially in old and frail patients. Percutaneous drainage (PT-GBD) and endosonographic guided drainage (EUS-GBD) could be an alternative option for relieving symptoms or act as a definitive treatment instead of a laparoscopic or open cholecystectomy (LC, OC). The aim of the present study was to compare different treatment groups. Materials and Methods: This is a five-year monocentric retrospective study including patients ≥65 years old who underwent an urgent operative procedure. A descriptive analysis was conducted comparing all treatment groups. A propensity score was estimated based on the ACS score, incorporated into a predictive model, and tested by recursive partitioning analysis. Results: 163 patients were included: 106 underwent a cholecystectomy (81 laparoscopic (LC) and 25 Open (OC)), 33 a PT-GBD and 21 EUS-GBD. The sample was categorized into three prognostic groups according to the adverse event occurrence rate. All patients treated with EUS-GBD or LC resulted in the low risk group, and the adverse event rate (AE) was 10/96 (10.4%). The AE was 4/28 (14.2%) and 21/36 (58.3%) in the middle- and high-risk groups respectively (p < 0.001). These groups included all the patients who underwent an OC or a PT-GBD. The PT-GBD group had a lower clinical success rate (55.5%) and higher RR (16,6%) when compared with other groups. Conclusions: Surgery still represents the gold standard for AC treatment. Nevertheless, EUS-GBD is a good alternative to PT-GBD in terms of clinical success, RR and AEs in all kinds of patients.

Common bile duct stones management: A network meta-analysis

BACKGROUND

Timely management is critical for treating symptomatic common bile duct (CBD) stones; however, a single optimal management strategy has yet to be defined in the acute care setting. Consequently, this systematic review and network meta-analysis, comparing one-stage (CBD exploration or intraoperative endoscopic retrograde cholangiopancreatography [ERCP] with simultaneous cholecystectomy) and two-stage (precholecystectomy or postcholecystectomy ERCP) procedures, was undertaken with the main outcomes of interest being postprocedural complications and hospital length of stay (LOS).

METHODS

PubMed, SCOPUS, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were methodically queried for articles from 2010 to 2021. The search terms were a combination of medical subject headings terms and the subsequent terms: gallstone; common bile duct (stone); choledocholithiasis; cholecystitis; endoscopic retrograde cholangiography/ERCP; common bile duct exploration; intraoperative, preoperative, perioperative, and postoperative endoscopic retrograde cholangiography; stone extraction; and one-stage and two-stage procedure. Studies that compared two procedures or more were included, whereas studies not recording complications (bile leak, hemorrhage, pancreatitis, perforation, intra-abdominal infections, and other infections) or LOS were excluded. A network meta-analysis was conducted to compare the four different approaches for managing CBD stones.

RESULTS

A total of 16 studies (8,644 participants) addressing the LOS and 41 studies (19,756 participants) addressing postprocedural complications were included in the analysis. The one-stage approaches were associated with a decrease in LOS compared with the two-stage approaches. Common bile duct exploration demonstrated a lower overall risk of complications compared with preoperative ERCP, but there were no differences in the overall risk of complications in the remaining comparisons. However, differences in specific postprocedural complications were detected between the four different approaches managing CBD stones.

CONCLUSION

This network meta-analysis suggests that both laparoscopic CBD exploration and intraoperative ERCP have equally good outcomes and provide a preferable single-anesthesia patient pathway with a shorter overall length of hospital stay compared with the two-stage approaches.

Potential Risk of Misjudgment in the Decision-making Process Based on the 2018 Tokyo Guidelines in Older Patients with Acute Cholecystitis

Objective The 2018 Tokyo Guidelines (TG18) were published to facilitate the decision-making processes (DMP), including the diagnosis and operation of acute cholecystitis (AC). However, only a few guidelines consider older adults. This study evaluated the DMP based on the TG18, focusing on older patients with AC. Methods This was a single-armed, single-center retrospective study. The primary outcome measure was the "undiagnosable" AC rate, and the secondary outcome measure was the degree of concordance of "unfit for surgery" decisions. Patients Two hundred and nine patients with AC. Results Sixty (28.7%) of 209 patients with AC were "undiagnosable" on admission based on the TG18 criteria. The numbers and rate of "undiagnosable" AC in patients ≤59, 60-79, and ≥80 years old were 4 (10.0%), 20 (24.4%), and 36 (41.4%), respectively (P<0.001). The multiple logistic regression analysis following the univariate analysis revealed that age >73 years old was the most significant risk factor for undiagnosable AC (P=0.006, odds ratio [OR]: 3.06, 95% confidence interval [CI]: 1.38-6.81). Female sex (P=0.033, OR: 2.09, 95% CI: 1.06-4.09) and severe AC (P=0.049, OR: 2.97, 95% CI: 1.01-8.76) were also significant risk factors for undiagnosable AC. The number of cases unfit for surgery based on the Charlson Comorbidity Index and American Society of Anesthesiologists physical status was 90 (43.1%) and 75 (35.9%), respectively. The κ value between these 2 indicators revealed a minimal concordance of 0.33 (95% CI: 0.20-0.47). Conclusion The DMP based on the TG18 potentially harbors a misjudgment risk, especially in older patients with AC (UMIN000047715).

Önemli komorbid durumları olan yaşlı hastalarda epidural anestezi altında kolesistektomi

Purpose: The aim of this study was to evaluate the surgical treatment of gallstone disease with open cholecystectomy under epidural anesthesia in elderly patients with significant comorbid conditions. Materials and Methods: We retrospectively analyzed 80 consecutive elderly patients over 65 years of age with significant comorbid conditions who underwent open cholecytectomy under epidural anesthesia for the surgical treatment of gallstone disease between January 1, 2009 and December 31, 2019, all performed by one surgeon. Results: Mean age was found 77 ± 16 years. Fifty of the patients (62.5%) were females. Forty-seven patients (58.75%) showed an American Society of Anesthesiologist Physical Status (ASA, PS) of 3. The most frequently associated comorbidity involved the cardiovascular system (46 patients, 57.5%). Surgical indications were acute cholecystitis (AC) in 37 patients (46.25%) and chronic cholecystitis in 32 patients (40%). Mean operation time was 55 ± 22 minutes. Hospital stay was mean 12 ± 5 days. Total complication rate was 38.75%, and pulmonary complication was the most frequently encountered (13.75%). 30-day mortality was seen in 5 patients (6.25%). Conclusion: In older, high-risk gallstone patients, an open cholecystectomy with epidural anesthesia may be recommended. For this patient population, the mortality and morbidity rates are acceptable.

The WSES/SICG/ACOI/SICUT/AcEMC/SIFIPAC guidelines for diagnosis and treatment of acute left colonic diverticulitis in the elderly

Acute left colonic diverticulitis (ALCD) in the elderly presents with unique epidemiological features when compared with younger patients. The clinical presentation is more nuanced in the elderly population, having higher in-hospital and postoperative mortality. Furthermore, geriatric comorbidities are a risk factor for complicated diverticulitis. Finally, elderly patients have a lower risk of recurrent episodes and, in case of recurrence, a lower probability of requiring urgent surgery than younger patients. The aim of the present work is to study age-related factors that may support a unique approach to the diagnosis and treatment of this problem in the elderly when compared with the WSES guidelines for the management of acute left-sided colonic diverticulitis. During the 1° Pisa Workshop of Acute Care & Trauma Surgery held in Pisa (Italy) in September 2019, with the collaboration of the World Society of Emergency Surgery (WSES), the Italian Society of Geriatric Surgery (SICG), the Italian Hospital Surgeons Association (ACOI), the Italian Emergency Surgery and Trauma Association (SICUT), the Academy of Emergency Medicine and Care (AcEMC) and the Italian Society of Surgical Pathophysiology (SIFIPAC), three panel members presented a number of statements developed for each of the four themes regarding the diagnosis and management of ALCD in older patients, formulated according to the GRADE approach, at a Consensus Conference where a panel of experts participated. The statements were subsequently debated, revised, and finally approved by the Consensus Conference attendees. The current paper is a summary report of the definitive guidelines statements on each of the following topics: diagnosis, management, surgical technique and antibiotic therapy.

Percutaneous Cholecystostomy for Acute Cholecystitis: A Three-Year Single-Centre Experience Including During COVID-19

Introduction Percutaneous cholecystostomy is a recognised treatment modality for acute cholecystitis. Traditionally, its use was reserved for patients deemed unfit for surgery. However, the coronavirus disease 2019 (COVID-19) pandemic had a detrimental effect on both elective and emergency surgery. The utilisation of cholecystostomy thus increased. Unanswered questions remain over timing with respect to interval cholecystectomy. We evaluated our local practice over the preceding three years. Methods A retrospective analysis was performed of all patients who had a percutaneous cholecystostomy inserted over a three-year period (1 January 2018-1 January 2021). The primary outcome was time to cholecystectomy. Secondary outcomes were cholecystostomy-related complications, 30-day mortality, cholecystectomy-related complications and length of postoperative hospital stay. Results A total of 31 patients were identified during the period. Thirteen (42%) patients went on to have a laparoscopic cholecystectomy. The median time interval from cholecystostomy to cholecystectomy was 97 days (interquartile range [IQR]: 81-140, minimum: 47 and maximum: 791). One case was complicated by small bowel perforation; this occurred after an interval of 106 days. The median length of postoperative stay was one day (IQR: 1-1, minimum: 0 and maximum: 4). Cholecystostomy-related complications were observed in four (13%) patients, whereby three became displaced and one developed blockage. Thirty-day mortality following cholecystostomy insertion was zero. Conclusions Percutaneous cholecystostomy is a safe and effective intervention for the management of acute cholecystitis. Interval cholecystectomy should be carefully considered; it may be safer to perform prior to 90 days.

Acute Cholecystitis Presenting With Septic Shock as the First Presentation in an Elderly Patient

Gangrenous cholecystitis (GC), a severe complication of acute cholecystitis, is associated with higher morbidity and mortality rates than uncomplicated cholecystitis. In this report, we present the case of an 81-year-old female with diabetes mellitus and hypertension who presented in the emergency department complaining of severe generalized abdominal pain for 10 days. The pain was associated with nausea and vomiting. She had septic shock, prompting admission, and was eventually diagnosed with perforated GC. Interventional radiology was conducted, and a cholecystostomy tube was placed under radiology guidance with continuous daily irrigation and intravenous antibiotic coverage for four weeks. Subsequently, the patient’s condition improved, and she was finally discharged.

Chronological trends in patients undergoing cholecystectomy in Korea: a nationwide health insurance claims study

Purpose

The incidence of gallstone disease and cholecystectomy is increasing worldwide. The aim of this study was to determine trends in the incidence of cholecystectomy in Korea.

Methods

The National Health Insurance Services database was used to determine patterns in proportion of cholecystectomy and cholecystostomy in the total population of Korea from 2003 to 2017. The age-standardized rate (ASR) was calculated to compare the cholecystectomy and cholecystostomy according to changes in the population structure over time. The ASR was investigated according to patient age, sex, socioeconomic status, use of computed tomography, and type of hospital to identify trends.

Results

The ASR per 100,000 based on the 2010 population of cholecystectomy cases increased markedly from 67.7 to 211.4 between 2003 and 2017. The ASR was consistently higher in female than male (71.9 vs. 63.6 in 2003, 221.8 vs. 201.8 in 2017). Furthermore, the ASR for cholecystectomy increased with age, and surgery for gallstone disease was performed more often at a specialized center than at other medical facilities. The length of hospital stay of cholecystectomy decreased steadily from 10.6 days in 2003 to 6.9 days in 2017.

Conclusion

This study shows that the incidence of cholecystectomy and cholecystostomy has steadily increased over the years in Korea, with a trend toward older age and higher socioeconomic status in patients undergoing cholecystectomy. Increasing use of computed tomography investigations could be a primary cause for this trend. An integrated strategy is needed to manage the increase in older patients undergoing cholecystectomy and shorten their hospital stay with medical safety.

Minimally Invasive Management of Acute Cholecystitis and Frailty Assessment in Geriatric Patients

The aim was to compare laparoscopic cholecystectomy (LC) with the percutaneous cholecystostomy (PC) for the management of acute lithiasic cholecystitis in geriatric patients and investigate the decision-making using frailty assessment. A retrospective analysis was performed in all patients aged over 65 years who were treated for acute cholecystitis at our hospital in a period of 5 years. Patients were divided in LC and PC groups. In total, 111 (54.1%) patients were subjected to LC and 94 (45.9%) to PC. The American Society of Anesthesiologists (ASA) and the Clinical Frailty Score were lower for the LC group. However, for patients over 85 years of age, frailty scores between groups were not statistically different. Morbidity and mortality between groups were not statistically different. Both LC and PC are safe and efficient in geriatric patients. Frailty score may better drive the selection of patients to be managed laparoscopically.

Clinical impact of bloodstream infection on acute cholecystitis indicated for emergency cholecystectomy

BACKGROUND

The significance of blood culture for acute cholecystitis remains unclear.

METHODS

A retrospective cohort study was conducted on patients who underwent emergency cholecystectomy at Hyogo Prefectural Amagasaki General Medical Center to examine the clinical impact of bloodstream infection (BSI), focusing on the association of BSI with bactibilia and severity grade based on the Tokyo guidelines 2018 (TG18).

RESULTS

Among 177 patients included in the study, 32 had positive and 145 had negative BSI. Significant differences were observed between the positive and negative BSI in terms of age, body mass index (BMI), the American Society of Anesthesiologists physical status (ASA-PS) and TG18 severity score. The odds ratios of BSI for patients aged ≥72 years, with a BMI of ≤21.8, an ASA-PS of ≥3E, and grade III acute cholecystitis were 3.45, 3.23, 2.43 and 4.51, respectively. In the multivariate analysis, lower BMI and grade III were significantly associated with BSI with odds ratios of 2.53 (95% confidence interval: 1.07-6.21, P = .037) and 3.03 (95% confidence interval: 1.02-8.82, P = .041). Bacterial species that could not be isolated in the bile culture alone were identified in blood culture on 10 (38.5%) of 26 patients.

CONCLUSIONS

Bloodstream infection is associated with grade III acute cholecystitis. Blood culture enables the identification of bacteria that cannot be isolated in bile culture. Blood culture should be obtained for patients with grade III acute cholecystitis who undergo emergency cholecystectomy.

A comparison of transhepatic versus transperitoneal cholecystostomy for acute calculous cholecystitis: a 5-year experience

Percutaneous cholecystostomy is a treatment for acute calculous cholecystitis used in patients where surgery is high risk or challenging either to allow for surgical optimisation or as definitive treatment. In this case series we compare the outcomes of a transhepatic versus transperitoneal approach in patients undergoing percutaneous cholecystostomy for acute calculous cholecystitis. A retrospective review of patients from 2014 to 2019 was conducted and included demographics, percutaneous cholecystostomy route, complications and outcome. Fifty-one patients were included. Percutaneous cholecystostomy was placed transhepatically in 15 cases; transperitoneal in 30 cases; 6 cases had undetermined route. The transhepatic cohort had 43.5% fewer readmissions due to biliary sepsis, 32.5% fewer drain-related complications, and were less likely to require further treatment (32.5% reduction) compared to the transperitoneal cohort. In our experience, the transhepatic route is preferred due to fewer complications, fewer readmissions and a reduction in the need for further treatment.

Surgical outcome of percutaneous transhepatic gallbladder drainage in acute cholecystitis: Ten years' experience at a tertiary care centre

Background

Percutaneous transhepatic gallbladder drainage (PTGBD) plays an important role in the treatment of elderly patients and/or patients in poor health with acute cholecystitis (AC). The primary aim of this study is to determine how these factors influence the clinical outcome of PTGBD. Moreover, we assessed the timing and results of subsequent cholecystectomies.

Patients and Methods

We retrospectively examined the results of 162 patients undergoing PTGBD between 2010 and 2020 (male–female ratio: 51.23% vs. 48.77%; mean age: 71.43 ± 13.22 years). Patient’s performance status and intervention outcomes were assessed with clinical success rates (CSR) and in-hospital mortality. The conversion rate (CR) of possible urgent or delayed, elective laparoscopic cholecystectomies (LC) after PTGBD were analysed.

Results

PTGBD was the definitive treatment in 42.18% of patients, while it was a bridging therapy prior to cholecystectomy (CCY) for the other patients. CSR was 87.97%, it was only 64.29% in grade III AC. In 9.87% of the cases, urgent LC was necessary after PTGBD, and its conversion rate was approximately equal to that of elective LC (18.18 vs. 17.46%, respectively, p = 0.2217). Overall, the post-PTGBD in-hospital mortality was 11.72%, while the same figure was 0% for grade I AC, 7.41% for grade II and 40.91% for grade III. Based on logistic regression analyses, in-hospital mortality (OR 6.07; CI 1.79–20.56), clinical progression (OR 7.62; CI 2.64–22.05) and the need for emergency CCY (OR 14.75; CI 3.07–70.81) were mostly determined by AC severity grade.

Conclusion

PTGBD is an easy-to-perform intervention with promising clinical success rates in the treatment of acute cholecystitis. After PTGBD, the level of gallbladder inflammation played a decisive role in the course of AC. In a severe, grade III inflammation, we have to consider low CSR and high mortality.

Patients over 65 years with Acute Complicated Calculous Biliary Disease are Treated Differently-Results and Insights from the ESTES Snapshot Audit

BACKGROUND

Accrued comorbidities are perceived to increase operative risk. Surgeons may offer operative treatments less often to their older patients with acute complicated calculous biliary disease (ACCBD). We set out to capture ACCBD incidence in older patients across Europe and the currently used treatment algorithms.

METHODS

The European Society of Trauma and Emergency Surgery (ESTES) undertook a snapshot audit of patients undergoing emergency hospital admission for ACCBD between October 1 and 31 2018, comparing patients under and ≥ 65 years. Mortality, postoperative complications, time to operative intervention, post-acute disposition, and length of hospital stay (LOS) were compared between groups. Within the ≥ 65 cohort, comorbidity burden, mortality, LOS, and disposition outcomes were further compared between patients undergoing operative and non-operative management.

RESULTS

The median age of the 338 admitted patients was 67 years; 185 patients (54.7%) of these were the age of 65 or over. Significantly fewer patients ≥ 65 underwent surgical treatment (37.8% vs. 64.7%, p < 0.001). Surgical complications were more frequent in the ≥ 65 cohort than younger patients, and the mean postoperative LOS was significantly longer. Postoperative mortality was seen in 2.2% of patients ≥ 65 (vs. 0.7%, p = 0.253). However, operated elderly patients did not differ from non-operated in terms of comorbidity burden, mortality, LOS, or post-discharge rehabilitation need.

CONCLUSIONS

Few elderly patients receive surgical treatment for ACCBD. Expectedly, postoperative morbidity, LOS, and the requirement for post-discharge rehabilitation are higher in the elderly than younger patients but do not differ from elderly patients managed non-operatively. With multidisciplinary perioperative optimization, elderly patients may be safely offered optimal treatment.

Simple Blood Tests May Be Used to Predict the Increased Risk of Conversion in Elective Laparoscopic Cholecystectomy Surgery

Background: In this study, we aimed to evaluate the possibility if simple blood tests that can be made in majority of hospitals may be used predict to risk of conversion to laparoscopic surgery to an open approach. Patients and Methods: The hospital records of 636 patients who underwent elective laparoscopic cholecystectomy (L-C) were retrospectively reviewed, and 583 patients included in the study protocol. Preoperative laboratory tests of all patients and data of patients who underwent conversion from laparoscopic surgery to open surgery were examined. Results: Of the 583 patients who were included in the study, 404 (69.29%) were female and the mean age was 50.02 ± 12.84 (19-89) years. The cholecystectomy was completed laparoscopically in 559 (89.5%) patients. The most common symptoms seen in the patients were epigastric discomfort and right upper quadrant pain. The high level of white blood cell (WBC) count and c-reactive protein (CRP) were found to be statistically significant before surgery in patients who had a conversion to open cholecystectomy (P < .001). Conclusion: Elevation of WBC count and CRP value before elective L-C may be useful in the prediction of a high risk of conversion from laparoscopic to open approach. This finding will help the surgeon to plan the treatment and inform the patient of the possibility before surgery.

Mortality risk estimation in acute calculous cholecystitis: beyond the Tokyo Guidelines

BACKGROUND

Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments. The recommended treatment is the early laparoscopic cholecystectomy; however, the Tokyo Guidelines (TG) advocate for different initial treatments in some subgroups of patients without a strong evidence that all patients will benefit from them. There is no clear consensus in the literature about who is the unfit patient for surgical treatment. The primary aim of the study is to identify the risk factors for mortality in ACC and compare them with Tokyo Guidelines (TG) classification.

METHODS

Retrospective unicentric cohort study of patients emergently admitted with and ACC during 1 January 2011 to 31 December 2016. The study comprised 963 patients. Primary outcome was the mortality after the diagnosis. A propensity score method was used to avoid confounding factors comparing surgical treatment and non-surgical treatment.

RESULTS

The overall mortality was 3.6%. Mortality was associated with older age (68 + IQR 27 vs. 83 + IQR 5.5; P = 0.001) and higher Charlson Comorbidity Index (3.5 + 5.3 vs. 0+2; P = 0.001). A logistic regression model isolated four mortality risk factors (ACME): chronic obstructive pulmonary disease (OR 4.66 95% CI 1.7-12.8 P = 0.001), dementia (OR 4.12; 95% CI 1.34-12.7, P = 0.001), age > 80 years (OR 1.12: 95% CI 1.02-1.21, P = 0.001) and the need of preoperative vasoactive amines (OR 9.9: 95% CI 3.5-28.3, P = 0.001) which predicted the mortality in a 92% of the patients. The receiver operating characteristic curve yielded an area of 88% significantly higher that 68% (P = 0.003) from the TG classification. When comparing subgroups selected using propensity score matching with the same morbidity and severity of ACC, mortality was higher in the non-surgical treatment group. (26.2% vs. 10.5%).

CONCLUSIONS

Mortality was higher in ACC patients treated with non-surgical treatment. ACME identifies high-risk patients. The validation to ACME with a prospective multicenter study population could allow us to create a new alternative guideline to TG for treating ACC.

Variations in volume of emergency surgeries and emergency department access at a third level hospital in Milan, Lombardy, during the COVID-19 outbreak

BACKGROUND

During the recent outbreak of COVID-19 (coronavirus disease 2019), Lombardy was the most affected region in Italy, with 87,000 patients and 15,876 deaths up to May 26, 2020. Since February 22, 2020, well before the Government declared a state of emergency, there was a huge reduction in the number of emergency surgeries performed at hospitals in Lombardy. A general decrease in attendance at emergency departments (EDs) was also observed. The aim of our study is to report the experience of the ED of a third-level hospital in downtown Milan, Lombardy, and provide possible explanations for the observed phenomena.

METHODS

This retrospective, observational study assessed the volume of emergency surgeries and attendance at an ED during the course of the pandemic, i.e. immediately before, during and after a progressive community lockdown in response to the COVID-19 pandemic. These data were compared with data from the same time periods in 2019. The results are presented as means, standard error (SE), and 95% studentized confidence intervals (CI). The Wilcoxon rank signed test at a 0.05 significance level was used to assess differences in per-day ED access distributions.

RESULTS

Compared to 2019, a significant overall drop in emergency surgeries (60%, p < 0.002) and in ED admittance (66%, p ≅ 0) was observed in 2020. In particular, there were significant decreases in medical (40%), surgical (74%), specialist (ophthalmology, otolaryngology, traumatology, and urology) (92%), and psychiatric (60%) cases. ED admittance due to domestic violence (59%) and individuals who left the ED without being seen (76%) also decreased. Conversely, the number of deaths increased by 196%.

CONCLUSIONS

During the COVID-19 outbreak the volume of urgent surgeries and patients accessing our ED dropped. Currently, it is not known if mortality of people who did not seek care increased during the pandemic. Further studies are needed to understand if such reductions during the COVID-19 pandemic will result in a rebound of patients left untreated or in unwanted consequences for population health.

Laparoscopic cholecystectomy for acute cholecystitis: onset of symptoms and severity grade as a tool for choosing the optimal timing

BACKGROUND

Acute cholecystitis is an acute inflammation of the gallbladder. It represents one-third of all surgical emergency hospital admissions and has significant socioeconomic impact. Laparoscopic cholecystectomy, regardless of age, is the gold standard for this disease, but the optimal timing of surgical intervention is an open issue since Tokyo guidelines 2007.

METHODS

We recruited from March 2015 to June 2018, in a retrospective study, 144 patients with acute cholecystitis and treated with laparoscopic cholecystectomy. The patients were divided into two groups: group A (n=66), operated within 72 hours and group B (n=78), between 72 hours and 1 week after the onset of symptoms. After, the two groups were further stratified by the grade of severity of acute cholecystitis in according to Tokyo guidelines: in group A, 39 patients were grade I and 27 grade II; in group B, 48 patients were grade I and 30 grade II.

RESULTS

The operative time was longer in group B patients versus group A. In group B, there was a greater difficulty in dissecting and detecting the Calot's triangle, more conversions to open, a greater mean length of hospital stay and more post-operative days. In patients with grade II, especially in the group B, were greater inflammation stage, conversions to open, difficulty in the dissection of the Calot's triangle, mean length of hospital stay and post-operative days. The operative timing within 72 hours in patients with grade I, have only advantage in the mean length of hospital stay, while in grade II, the advantages are also in the lesser difficulty in dissecting the Calot's triangle, fewer conversions and fewer post-operative days.

CONCLUSIONS

Early laparoscopic cholecystectomy for acute cholecystitis should be performed considering not only the onset of symptoms, but above all the grade of severity of AC in according with TG. Grade II, particularly, must be treated within 72 hours and by experienced surgeon.

2020 World Society of Emergency Surgery updated guidelines for the diagnosis and treatment of acute calculus cholecystitis

BACKGROUND

Acute calculus cholecystitis (ACC) has a high incidence in the general population. The presence of several areas of uncertainty, along with the availability of new evidence, prompted the current update of the 2016 WSES (World Society of Emergency Surgery) Guidelines on ACC.

MATERIALS AND METHODS

The WSES president appointed four members as a scientific secretariat, four members as an organization committee and four members as a scientific committee, choosing them from the expert affiliates of WSES. Relevant key questions were constructed, and the task force produced drafts of each section based on the best scientific evidence from PubMed and EMBASE Library; recommendations were developed in order to answer these key questions. The quality of evidence and strength of recommendations were reviewed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria (see https://www.gradeworkinggroup.org/ ). All the statements were presented, discussed and voted upon during the Consensus Conference at the 6th World Congress of the World Society of Emergency Surgery held in Nijmegen (NL) in May 2019. A revised version of the statements was voted upon via an online questionnaire until consensus was reached.

RESULTS

The pivotal role of surgery is confirmed, including in high-risk patients. When compared with the WSES 2016 guidelines, the role of gallbladder drainage is reduced, despite the considerable technical improvements available. Early laparoscopic cholecystectomy (ELC) should be the standard of care whenever possible, even in subgroups of patients who are considered fragile, such as the elderly; those with cardiac disease, renal disease and cirrhosis; or those who are generally at high risk for surgery. Subtotal cholecystectomy is safe and represents a valuable option in cases of difficult gallbladder removal.

CONCLUSIONS, KNOWLEDGE GAPS AND RESEARCH RECOMMENDATIONS

ELC has a central role in the management of patients with ACC. The value of surgical treatment for high-risk patients should lead to a distinction between high-risk patients and patients who are not suitable for surgery. Further evidence on the role of clinical judgement and the use of clinical scores as adjunctive tools to guide treatment of high-risk patients and patients who are not suitable for surgery is required. The development of local policies for safe laparoscopic cholecystectomy is recommended.

Perioperative outcomes after laparoscopic cholecystectomy in elderly patients: a systematic review and meta-analysis

BACKGROUND

Laparoscopic cholecystectomy is increasingly performed in an ever ageing population; however, the risks are poorly quantified. The study aims to review the current evidence to quantify further the postoperative risk of cholecystectomy in the elderly population compared to younger patients.

METHOD

A systematic literature search of PubMed, EMBASE and the Cochrane Library databases were conducted including studies reporting laparoscopic cholecystectomy in the elderly population. A meta-analysis was reported in accordance with the recommendations of the Cochrane Library and PRISMA guidelines. Primary outcome was overall complications and secondary outcomes were conversion to open surgery, bile leaks, postoperative mortality and length of stay.

RESULTS

This review identified 99 studies incorporating 326,517 patients. Increasing age was significantly associated with increased rates of overall complications (OR 2.37, CI95% 2.00-2.78), major complication (OR 1.79, CI95% 1.45-2.20), risk of conversion to open cholecystectomy (OR 2.17, CI95% 1.84-2.55), risk of bile leaks (OR 1.50, CI95% 1.07-2.10), risk of postoperative mortality (OR 7.20, CI95% 4.41-11.73) and was significantly associated with increased length of stay (MD 2.21 days, CI95% 1.24-3.18).

CONCLUSION

Postoperative outcomes such as overall and major complications appear to be significantly higher in all age cut-offs in this meta-analysis. This study demonstrated there is a sevenfold increase in perioperative mortality which increases by tenfold in patients > 80 years old. This study appears to confirm preconceived suspicions of higher risks in elderly patients undergoing cholecystectomy and may aid treatment planning and informed consent.

Laparoendoscopic rendezvous versus ERCP followed by laparoscopic cholecystectomy in the management of cholecystocholedocholithiasis: a systemic review and meta-analysis

BACKGROUND

The ideal management for patients with cholecystocholedocholithiasis is still controversial. Laparoendoscopic rendezvous (LERV), combined with laparoscopy and endoscopy, is a novel and attractive technique. The aim of this research was to compare LERV with traditional two-stage management, preoperative ERCP and laparoscopic cholecystectomy (ERCP + LC), for treating patients with cholecystocholedocholithiasis.

METHOD

Four databases, the Cochrane Library, PubMed, Embase, and Medline, all updated to through September 2019, were searched to identify comparative studies on LERV versus ERCP + LC for treating cholecystocholedocholithiasis. Total operative time, successful common bile duct (CBD) stone clearance, postoperative morbidity, conversion to other procedures, and length of hospital stay were evaluated. Pooled data were measured by odds ratios (ORs) and mean difference (MD) with 95% confidence intervals (CIs).

RESULTS

Eight studies with a total of 1061 patients were included in this meta-analysis, including 542 patients who received LERV and 519 patients who received ERCP + LC. There was no significant difference between the two groups regarding successful CBD stone clearance (OR 2.20, P = 0.10), postoperative bleeding (OR 0.67, P = 0.37), postoperative cholangitis (OR 0.66, P = 0.53), postoperative bile leak (OR 0.87, P = 0.81), or conversion to other procedures (OR 0.75, P = 0.62). The total operative time was longer in the LERV group (MD = 44.93, P < 0.00001), while LERV was associated with less postoperative pancreatitis than the two-stage management group (OR 0.26, P = 0.0003). The incidence of overall morbidity was lower in the LERV group than in the two-stage management group (OR 0.41, P < 0.0001), and the LERV group had a shorter hospital stay (MD = - 3.52, P < 0.00001).

CONCLUSION

LERV is equivalent to traditional two-stage procedures in terms of CBD stone clearance and conversion, with less pancreatitis, lower overall morbidity, and shorter hospital stay but longer operation time. More clinical trials are needed to determine the best treatment for patients in different conditions.

Acute cholecystitis during COVID-19 pandemic: a multisocietary position statement

Following the spread of the infection from the new SARS-CoV2 coronavirus in March 2020, several surgical societies have released their recommendations to manage the implications of the COVID-19 pandemic for the daily clinical practice. The recommendations on emergency surgery have fueled a debate among surgeons on an international level.We maintain that laparoscopic cholecystectomy remains the treatment of choice for acute cholecystitis, even in the COVID-19 era. Moreover, since laparoscopic cholecystectomy is not more likely to spread the COVID-19 infection than open cholecystectomy, it must be organized in such a way as to be carried out safely even in the present situation, to guarantee the patient with the best outcomes that minimally invasive surgery has shown to have.

The use of emergency laparoscopy for acute abdomen in the elderly: the FRAILESEL Italian Multicenter Prospective Cohort Study

As the world population is aging rapidly, emergency abdominal surgery for acute abdomen in the elderly represents a global issue, both in developed and developing countries. Data regarding all the elderly patients who underwent emergency abdominal surgery from January 2017 to December 2017 at 36 Italian surgical departments were analyzed with the aim to appraise the contemporary reality regarding the use of emergency laparoscopy for acute abdomen in the elderly. 1993 patients were enrolled. 1369 (68.7%) patients were operated with an open technique; whereas, 624 (31.3%) underwent a laparoscopic operation. The postoperative morbidity rate was 32.6%, with a statically significant difference between the open and the laparoscopic groups (36.2% versus 22.1%, p < 0.001). The reported mortality rate was 8.8%, with a statistically significant difference between the open and the laparoscopic groups (11.2% versus 2.2%, p < 0.001). Our results demonstrated that patients in the ASA II (58.1%), ASA III (68.7%) and ASA IV (88.5%) groups were operated with the traditional open technique in most of the cases. Only a small percentage of patients underwent laparoscopy for perforated gastro-duodenal ulcer repair (18.9%), adhesiolyses with/without small bowel resection (12.2%), and large bowel resection (10.7%). Conversion to open technique was associated with a higher mortality rate (11.1% versus 2.2%, p < 0.001) and overall morbidity (38.9% versus 22.1%, p = 0.001) compared with patients who did not undergo conversion. High creatinine (p < 0.001) and glycaemia (p = 0.006) levels, low hemoglobin levels (p < 0.001), oral anticoagulation therapy (p = 0.001), acute respiratory failure (p < 0.001), presence of malignancy (p = 0.001), SIRS (p < 0.001) and open surgical approach (p < 0.001) were associated with an increased risk of postoperative morbidity. Regardless of technical progress, elderly patients undergoing emergency surgery are at very high risk for in-hospital complications. A detailed analysis of complications and mortality in the present study showed that almost 9% of elderly patients died after surgery for acute abdomen, and over 32% developed complications.

Endosonography-guided gallbladder drainage versus percutaneous cholecystostomy in very high-risk surgical patients with acute cholecystitis: an international randomised multicentre controlled superiority trial (DRAC 1)

OBJECTIVE

The optimal management of acute cholecystitis in patients at very high risk for cholecystectomy is uncertain. The aim of the current study was to compare endoscopic ultrasound (EUS)-guided gallbladder drainage (EUS-GBD) to percutaneous cholecystostomy (PT-GBD) as a definitive treatment in these patients under a randomised controlled trial.

DESIGN

Consecutive patients suffering from acute calculous cholecystitis but were at very high-risk for cholecystectomy were recruited. The primary outcome was the 1-year adverse events rate. Secondary outcomes include technical and clinical success, 30-day adverse events, pain scores, unplanned readmissions, re-interventions and mortalities.

RESULTS

Between August 2014 to February 2018, 80 patients were recruited. EUS-GBD significantly reduced 1 year adverse events (10 (25.6%) vs 31 (77.5%), p<0.001), 30-day adverse events (5 (12.8%) vs 19 (47.5%), p=0.010), re-interventions after 30 days (1/39 (2.6%) vs 12/40 (30%), p=0.001), number of unplanned readmissions (6/39 (15.4%) vs 20/40 (50%), p=0.002) and recurrent cholecystitis (1/39 (2.6%) vs 8/40 (20%), p=0.029). Postprocedural pain scores and analgesic requirements were also less (p=0.034). The technical success (97.4% vs 100%, p=0.494), clinical success (92.3% vs 92.5%, p=1) and 30-day mortality (7.7% vs 10%, p=1) were statistically similar. The predictor to recurrent acute cholecystitis was the performance of PT-GBD (OR (95% CI)=5.63 (1.20-53.90), p=0.027).

CONCLUSION

EUS-GBD improved outcomes as compared to PT-GBD in those patients that not candidates for cholecystectomy. EUS-GBD should be the procedure of choice provided that the expertise is available after a multi-disciplinary meeting. Further studies are required to determine the long-term efficacy.

The SIFIPAC/WSES/SICG/SIMEU guidelines for diagnosis and treatment of acute appendicitis in the elderly (2019 edition)

The epidemiology and the outcomes of acute appendicitis in elderly patients are very different from the younger population. Elderly patients with acute appendicitis showed higher mortality, higher perforation rate, lower diagnostic accuracy, longer delay from symptoms onset and admission, higher postoperative complication rate and higher risk of colonic and appendiceal cancer. The aim of the present work was to investigate age-related factors that could influence a different approach, compared to the 2016 WSES Jerusalem guidelines on general population, in terms of diagnosis and management of elderly patient with acute appendicitis. During the XXIX National Congress of the Italian Society of Surgical Pathophysiology (SIFIPAC) held in Cesena (Italy) in May 2019, in collaboration with the Italian Society of Geriatric Surgery (SICG), the World Society of Emergency Surgery (WSES) and the Italian Society of Emergency Medicine (SIMEU), a panel of experts participated to a Consensus Conference where eight panelists presented a number of statements, which were developed for each of the four topics about diagnosis and management of acute appendicitis in elderly patients, formulated according to the GRADE system. The statements were then voted, eventually modified and finally approved by the participants to the Consensus Conference. The current paper is reporting the definitive guidelines statements on each of the following topics: diagnosis, non-operative management, operative management and antibiotic therapy.
