Gallbladder torsion.

ABSTRACT: Gallbladder torsion is a rare cause of acute surgical abdomen. Early recognition and surgical intervention are important for reducing complications and improving postoperative patient outcomes, but standard imaging and laboratory evaluation typically are indistinguishable from those of acute cholecystitis. This article describes a patient with gangrenous cholecystitis secondary to torsion and summarizes recommendations for evaluation and management.

Risk factors and treatment strategies for cholecystitis after metallic stent placement for malignant biliary obstruction: a multicenter retrospective study.

BACKGROUND AND AIMS: Cholecystitis can occur after self-expandable metallic stent (SEMS) placement for malignant biliary obstruction (MBO), but the best treatment option for cholecystitis has not been determined. Here, we aimed to identify the risk factors of cholecystitis after SEMS placement and determine the best treatment option. METHODS: Incidence, treatments, and predictive factors of cholecystitis were retrospectively evaluated in 1084 patients with distal MBO (DMBO) and 353 patients with hilar MBO (HMBO) who underwent SEMS placement at 12 institutions from January 2012 to March 2021. RESULTS: Cholecystitis occurred in 7.5% of patients with DMBO and 5.9% of patients with HMBO. The recurrence rate was significantly lower (P = .043) and the recurrence-free period significantly longer (P = .039) in endoscopic procedures than in percutaneous procedures for cholecystitis treatment. EUS-guided gallbladder drainage (EUS-GBD) was better in terms of technical success, procedure time, and recurrence-free period than endoscopic transpapillary gallbladder drainage. Obstruction across the cystic duct orifice by tumor (P = .015) and by stent (P = .037) were independent risk factors for cholecystitis in DMBO. Cases with multiple SEMS placements (odds ratio [OR], 11; 95% confidence interval [CI], 0.68-190; P = .091) and with gallbladder stones (OR, 2.3; 95% CI ,0.92-5.6; P = .075) had a higher risk for cholecystitis in HMBO. CONCLUSIONS: The incidences of cholecystitis after SEMS placement for DMBO and HMBO were similar. EUS-GBD is the optimal treatment option for patients with cholecystitis after SEMS placement for MBO.

Post-ERCP cholecystitis: Incidence, characteristics, and outcomes from a prospective multicenter biliary endoscopy registry.

BACKGROUND AND AIMS: The incidence, risk factors, and outcomes of post-ERCP cholecystitis are poorly described. We aimed to describe cases of post-ERCP cholecystitis from a prospective multicenter registry with protocolized 30-day follow-up. METHODS: Patient- and procedure-related data from 7 centers were obtained. The primary outcome was post-ERCP cholecystitis, defined according to a Delphi-based criteria and causal attribution system. Risk factors and outcomes were described for all cases. RESULTS: Seventeen cases of post-ERCP cholecystitis were identified among 4428 patients with gallbladders undergoing ERCP between 2018 and 2023 (incidence, 0.38%; 95% confidence interval, 0.20-0.57). In ERCPs with covered metal stenting, 7 of 467 resulted in cholecystitis (incidence, 1.50%; 95% confidence interval, 0.40-2.60). Patients had symptoms at a median of 5 days (interquartile range, 5) after ERCP. Management strategies included cholecystectomy, percutaneous cholecystostomy, and endoscopic stent removal/exchange. CONCLUSIONS: Estimates of post-ERCP cholecystitis incidence can inform discussions around procedural risk.

Adverse events of self-expandable metal stent placement for malignant distal biliary obstruction: a large multicenter study.

BACKGROUND AND AIMS: Endoscopic placement of self-expandable metal stents (SEMSs) for malignant distal biliary obstruction (MDBO) may be accompanied by several types of adverse events. The present study analyzed the adverse events occurring after SEMS placement for MDBO. METHODS: The present study retrospectively investigated the incidence and types of adverse events in patients who underwent SEMS placement for MDBO between April 2018 and March 2021 at 26 hospitals. Risk factors for acute pancreatitis, cholecystitis, and recurrent biliary obstruction (RBO) were evaluated by univariate and multivariate analyses. RESULTS: Of the 1425 patients implanted with SEMSs for MDBO, 228 (16.0%) and 393 (27.6%) experienced early adverse events and RBO, respectively. Pancreatic duct without tumor involvement (P = .023), intact papilla (P = .025), and SEMS placement across the papilla (P = .037) were independent risk factors for acute pancreatitis. Tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis (P < .001). Use of fully and partially covered SEMSs was an independent risk factor for food impaction and/or sludge. Use of fully covered SEMSs was an independent risk factor for stent migration. Use of uncovered SEMSs and laser-cut SEMSs was an independent risk factor for tumor ingrowth. CONCLUSIONS: Pancreatic duct without tumor involvement, intact papilla, and SEMS placement across the papilla were independent risk factors for acute pancreatitis, and tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis. The risk factors for food impaction and/or sludge, stent migration, and tumor ingrowth differed among types of SEMSs.

Endoscopic Ultrasound-Guided Naso-gallbladder Drainage Using a Dedicated Catheter for Acute Cholecystitis After Transpapillary Metal Stent Placement for Malignant Biliary Obstruction.

BACKGROUND: Acute cholecystitis is a significant adverse event after self-expandable metal stent (SEMS) placement for malignant biliary obstruction (MBO); however, no appropriate treatment strategy has been established for its management. AIMS: This study aimed to examine the feasibility and utility of endoscopic ultrasound-guided naso-gallbladder drainage (EUS-NGBD) for the management of acute cholecystitis occurring after SEMS placement. METHODS: This retrospective study investigated consecutive patients with acute cholecystitis after SEMS placement for unresectable MBO, in whom EUS-NGBD was attempted. The study outcomes included technical success, clinical success, procedure time, adverse event, and cholecystitis recurrence, associated with the procedure. RESULTS: During the study period, EUS-NGBD was performed for SEMS-related acute cholecystitis in 30 patients with MBO. The technical and clinical success rates were 96.7% (29/30) and 96.6% (28/29), respectively. The median procedure time was 15 min, and rate of procedure-related adverse event was 3.3% (1/30). The median duration from the procedure to tube removal was 9 days. No adverse events were observed after removal. The median hospitalization duration after the procedure was 14 days, and the median duration to the (re-)start of chemotherapy from cholecystitis onset was 13 days. The median overall survival after EUS-NGBD was 123 days, and the rate of cholecystitis recurrence until death was 4.2% (1/28). CONCLUSIONS: This study demonstrated that EUS-NGBD possesses good technical and clinical feasibility with an acceptable adverse event rates and short hospitalization and chemotherapy withdrawal period. Therefore, EUS-NGBD may be a good option for the treatment of SEMS-related cholecystitis in patients with MBO.

Risk factors for early and late cholecystitis after covered metal stent placement for distal biliary obstruction.

BACKGROUND: Cholecystitis is a major adverse event after self-expandable metallic stent placement for distal biliary obstruction (DBO). Covered self-expandable metallic stent (CSEMS) is being increasingly used, but few studies have investigated risk factors for cholecystitis limited to CSEMS. The present study aimed to identify risk factors for cholecystitis after CSEMS. METHODS: Patients who underwent initial CSEMS placement for DBO between November 2014 and September 2021 were enrolled and followed-up until death, recurrent biliary obstruction, cholecystitis, or until March 2022. Cholecystitis within 30 days of CSEMS was defined as early cholecystitis and after 30 days as late cholecystitis. RESULTS: Cholecystitis occurred in 51 of 339 patients (15%) after CSEMS. Forty-one patients (80.4%) had early cholecystitis, and 10 (19.6%) had late cholecystitis. Multivariate logistic regression analysis revealed that the maximum diameter of the common bile duct (CBD) (per 1 mm increase) (odds ratio [OR]: 0.87; 95% confidence interval [CI]: 0.76-1.00; p = .044), gallbladder stones (OR: 3.63; 95% CI: 1.62-8.10; p = .002), and tumor involvement in the cystic duct (CD) (OR: 4.87; 95% CI: 2.16-11.00; p < .001) were significant independent risk factors associated with early cholecystitis. No significant risk factors were identified for late cholecystitis. CONCLUSIONS: A smaller CBD diameter, gallbladder stones, and tumor involvement in the CD were identified as risk factors for early cholecystitis development after CSEMS.

Primary admission to a surgical service facilitates early cholecystectomy in acute cholecystitis but does not influence patient outcome.

PURPOSE: Early cholecystectomy is recommended for acute calculous cholecystitis to reduce complications and lower health care costs. However, not all patients admitted to emergency services due to acute calculous cholecystitis are considered for surgery immediately. Our intention was therefore to evaluate patient management and outcome parameters following cholecystectomy depending on the type of emergency service patients are primarily admitted to. METHODS: We performed a retrospective analysis of all patients that were treated for acute cholecystitis at our hospital between 2014 and 2021. Only patients that underwent surgical treatment for acute calculous cholecystitis were included. Patients with cholecystectomies that were performed due to other medical conditions were not incorporated. Primary outcomes were the perioperative length of stay and postoperative complications. Perioperative antimicrobial management and disease deterioration according to Tokyo Guidelines from 2018 due to inhouse organization were assessed as secondary outcome parameters. RESULTS: Of 512 patients included in our final analysis, 334 patients were primarily admitted to a surgical emergency service (SAG) whereas 178 were initially treated in a medical service (MAG). The latency between admission and cholecystectomy was significantly prolonged in the MAG with a median time to surgery of 2 days (Q25 1, Q75 3.25, IQR 2.25) compared to the SAG with a median time to surgery of 1 day (Q25 1, Q75 2, IQR 1) (p < 0.001). The duration of surgery was comparable between both groups. Necrotizing cholecystitis (27.2% vs. 38.8%, p = 0.007) and pericholecystic abscess or gallbladder perforation (7.5% vs. 14.6% p = 0.010) were less frequently described in the SAG. In the SAG, 85.7% of CCEs were performed laparoscopically, 6.0% were converted to open, and 10.4% were performed as open surgery upfront. In the MAG, 80.9% were completed laparoscopically, while 7.2% were converted and 11.2% were performed via primary laparotomy (p = 0.743). Histologically gangrenous cholecystitis was confirmed in 38.0% of the specimen in the SAG compared to 47.8% in the MAG (p = 0.033). While the prolonged preoperative stay led to prolonged overall length of stay, the postoperative length of stay was similar at a median of 3 days in both groups. CONCLUSIONS: To our knowledge, we present the largest single center cohort of acute calculous cholecystitis evaluating the perioperative management and outcome of patients admitted to either medical or surgical service prior to undergoing cholecystectomy. In patients that were primarily admitted to medical emergency services, we found disproportionately more gallbladder necrosis, perforation, and gangrene. Despite prolonged time intervals between admission and cholecystectomy in the MAG and advanced cases of cholecystitis, we did not record a prolonged procedure duration, conversion to open surgery, or complication rate. However, patients with acute calculous cholecystitis should either be primarily admitted to a surgical emergency service or at least a surgeon should be consulted at the time of diagnosis in order to avoid disease progression and unnecessary health care costs.

Percutaneous cholecystostomy as a definitive treatment for acute acalculous cholecystitis: clinical outcomes and risk factors for recurrent cholecystitis.

OBJECTIVE: To investigate the outcomes of percutaneous cholecystostomy (PC) as a definitive treatment for acute acalculous cholecystitis (AAC) and to identify the risk factors for cholecystitis recurrence after catheter removal. METHODS: Between January 2008 and December 2017, 124 patients who had undergone PC as definitive treatment for moderate or severe AAC. The initial clinical success, complications, and recurrent cholecystitis after PC removal were retrospectively assessed. Twenty-one relevant variables were analyzed to identify risk factors for recurrent cholecystitis. RESULTS: Clinical effectiveness was achieved in 107 patients (86.3%) at 3 days and in all patients (100%) at 5 days after PC placement. Six Grade 2 adverse events occurred, including catheter dislodgement (n = 3) and clogging (n = 3), which required catheter exchange. The PC catheter was removed in 123 patients (99.2%), with a median indwelling duration of 18 days (range 5-116 days). During the follow-up period (median, 1624 days; range, 40-4945 days), five patients experienced recurrent cholecystitis (4.1%). The cumulative recurrence rates were 3.3%, 4.1%, and 4.1% at 6 months, 1 year, and 5 years, respectively. Multivariate analysis revealed that an age-adjusted Charlson comorbidity index (aCCI)≥7 positively correlated with recurrence (OR, 1.97; 95% confidence interval, 1.07-3.64; p = 0.029). CONCLUSIONS: Definitive PC is a safe and effective treatment option for patients with AAC. The PC catheters can be safely removed in most patients. An aCCI≥7 was a risk factor for cholecystitis recurrence after catheter removal. ADVANCES IN KNOWLEDGE: 1. Percutaneous cholecystostomy (PC) is a safe and effective as a definitive treatment in patients with acute acalculous cholecystitis (AAC).2. PC can be safely removed after recover from AAC in the majority of patients (99.2%) with low rate of recurrence of cholecystitis (4.1%).3. Age-adjusted Charlson comorbidity index ≥7 was a risk factor for recurrence of cholecystitis after PC removal.

Comparison of the long-term outcomes of EUS-guided gallbladder drainage and endoscopic transpapillary gallbladder drainage for calculous cholecystitis in poor surgical candidates: a multicenter propensity score-matched analysis.

BACKGROUND AND AIMS: Although long-term stent placement using endoscopic transpapillary gallbladder drainage (ETGBD) and EUS-guided gallbladder drainage (EUS-GBD) reportedly reduces cholecystitis recurrence, comparative evidence of their safety and efficacy is scarce. This study aimed to examine and compare the long-term utility of EUS-GBD versus that of ETGBD in poor surgical candidates. METHODS: A total of 379 high-risk surgical patients with acute calculous cholecystitis met the eligibility criteria for enrollment in this study. The technical success and adverse events (AEs) were compared between the EUS-GBD and ETGBD groups, and propensity score matching was performed to adjust for differences between the groups. Both groups underwent plastic stent placement, and scheduled stent exchange and removal were not performed in either group. RESULTS: The technical success rate of EUS-GBD was significantly higher than that of ETGBD (96.7% vs 78.9%, P < .001), whereas the early AE rate did not differ significantly between the 2 methods (7.8% vs 8.9%, P = 1.000). The rate of recurrent cholecystitis did not differ significantly (3.8% vs 3.0%, P = 1.000), but the rate of symptomatic late AEs, in addition to cholecystitis, was significantly lower with EUS-GBD than with ETGBD (1.3% vs 13.4%, P = .006). Consequently, the overall late AE rate was significantly lower with EUS-GBD (5.0% vs 16.4%, P = .029). Multivariate analysis revealed that EUS-GBD was associated with a significantly longer time to late AE (hazard ratio, .26; 95% confidence interval, .10-.67; P = .005). CONCLUSIONS: Long-term stent placement via EUS-GBD is a promising potential option for limiting late AEs, including recurrence, in poor surgical candidates with calculous cholecystitis.

Prophylactic endoscopic gallbladder stent placement for cholecystitis after covered metal stent placement for distal biliary obstruction (with video).

BACKGROUND AND AIMS: Acute cholecystitis is occasionally observed after biliary drainage using a covered self-expandable metal stent (CSEMS) for distal biliary obstruction (DBO). Gallbladder drainage before CSEMS placement may reduce cholecystitis. This study aimed to examine the preventive effect of endoscopic gallbladder stent placement (EGBS) on cholecystitis with CSEMSs. METHODS: We retrospectively analyzed patients with DBO who underwent CSEMS placement across the orifice of the cystic duct between November 2014 and October 2021 and were negative for cholecystitis on biliary drainage. Prophylactic EGBS was attempted before CSEMS placement. The incidence of cholecystitis was compared between patients with and without EGBS. RESULTS: In total, 286 patients (128 men; median age, 75 years) were included in this study. EGBS was attempted in 32 patients before CSEMS placement, and technical success was achieved in 24 patients (75%). Adverse events were noted in 3 patients (9.4%; penetration of cystic duct in 1 and acute pancreatitis in 2). The cumulative incidence of cholecystitis was significantly lower in patients with EGBS than in those without EGBS (1 [4.2%] vs 56 [21.4%], P = .045). In multivariable analysis, EGBS was a significant protective factor against cholecystitis (hazard ratio, .11; 95% confidence interval, .01-.79; P = .028). CONCLUSIONS: Although the transpapillary approach to the gallbladder is not easy for patients with DBO, EGBS is effective in preventing cholecystitis associated with CSEMS placement.

Long-term outcomes of endoscopic ultrasound-guided gallbladder drainage versus in situ or ex situ percutaneous gallbladder drainage in real-world practice.

OBJECTIVES: Many studies showed better outcomes of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) when compared with percutaneous transhepatic gallbladder drainage (P-GBD) in which most tubes were left in situ. However, no studies have directly compared EUS-GBD with P-GBD after tube removal (ex situ). We compared the long-term outcomes of EUS-GBD and ex situ or in situ P-GBD in high surgical risk patients with acute cholecystitis. METHODS: We reviewed the records of 182 patients (EUS-GBD, n = 75; P-GBD, n = 107) who underwent gallbladder drainage. The procedural outcomes, long-term outcomes, and adverse events were compared. RESULTS: The EUS-GBD group and the P-GBD group had similar rates of technical and clinical success. Early adverse events were less common in the EUS-GBD group (5.5% vs. 18.9%, P = 0.010). The long-term outcomes were evaluated in 168 patients (EUS-GBD, n = 67; P-GBD ex situ, n = 84; P-GBD in situ, n = 17). The rate of cholecystitis recurrence in the EUS-GBD group (6.0%) was similar to that in the P-GBD ex situ group (9.6%, P = 0.422), but significantly lower than that in the P-GBD in situ group (23.5%, P = 0.049). P-GBD in situ was a significant predictor of recurrent cholecystitis (hazard ratio 14.6; 95% confidence interval 2.9-72.8). CONCLUSION: The long-term recurrence rate of acute cholecystitis in patients who underwent EUS-GBD was comparable to that in patients whose P-GBD could be removed. However, patients in whom P-GBD could not be removed showed higher rates of recurrent cholecystitis than patients with EUS-GBD.

Long-Term Impact of Endoscopic Gallbladder Stenting for Calculous Cholecystitis in Poor Surgical Candidates: A Multi-center Comparative Study.

BACKGROUND: Although long-term stent placement using endoscopic gallbladder stenting (EGBS) reportedly reduces cholecystitis recurrence in patients unfit to undergo cholecystectomy, its efficacy and safety remain uncertain. AIMS: This study aimed to examine the long-term effect of EGBS in poor surgical candidates of cholecystectomy. METHODS: A total of 528 high-risk surgical patients with acute calculous cholecystitis met this study's eligibility criteria. The technical success and adverse events (AE) were compared between patients who underwent EGBS and those who underwent percutaneous transhepatic gallbladder drainage (PTGBD). Elective stent exchange and removal were not performed after EGBS. The external tube was removed after improvement of cholecystitis following PTGBD. RESULTS: The technical success rate was significantly lower with EGBS compared to PTGBD (75.4% versus 98.7%, P < 0.001), while the early-AE rate did not differ significantly between the two methods (7.7% versus 4.3%, P = 0.146). The 1-, 3-, and 5-year cumulative incidence rates of cholecystitis were 3.8%, 7.2%, and 7.2% with EGBS, and 11.7%, 17.6%, and 30.2% with PTGBD, respectively (P = 0.001). Conversely, those of symptomatic late-AE (except cholecystitis) were 8.2%, 22.7%, and 31.4% with EGBS, and 7.5%, 10.9%, and 13.1% with PTGBD, respectively (P = 0.035). Thus, the 1-, 3-, and 5-year cumulative incidence of overall late-AE was 12.0%, 30.4%, and 40.4% with EGBS, and 19.2%, 28.3%, and 42.5% with PTGBD, respectively (P = 0.649). CONCLUSIONS: Long-term stent placement via EGBS is useful for preventing the recurrence of cholecystitis, but the success rate is low and the frequency of other late-AE increases with the prolongation of the indwelling period.

Long-term outcomes of endoscopic transpapillary gallbladder drainage using a novel spiral plastic stent in acute calculus cholecystitis.

BACKGROUND: Endoscopic transpapillary gallbladder stenting (EGBS) is considered for patients with contraindications to early surgery for acute calculus cholecystitis. However, evidence regarding the long-term outcomes of EGBS is insufficient to date. The aim of the study was to evaluate the feasibility of EGBS as a bridge to or alternative to surgery when there are contraindications. METHODS: We reviewed the cases of patients who underwent EGBS using a novel spiral-shaped plastic stent for acute calculus cholecystitis between January 2011 and December 2019. We retrospectively evaluated the long-term outcomes of EGBS using a novel spiral-shaped plastic stent. RESULTS: Forty-nine patients were included. The clinical success rate of EGBS was 97%. After EGBS, 25 patients (surgery group) underwent elective cholecystectomy and 24 patients did not (follow-up group). In the surgery group, the median period from EGBS to surgery was 93 days. There was a single late adverse event with cholecystitis recurrence. In the follow-up group, the median follow-up period was 236 days. Late adverse events were observed in eight patients, including recurrence of cholecystitis (four patients), duodenal penetration by the distal stent end (two patients), and distal stent migration (two patient). In the follow-up group, the time to recurrence of biliary obstruction was 527 days. CONCLUSIONS: EGBS with a novel spiral-shaped plastic stent is safe and effective for long-term acute calculus cholecystitis. There is a possibility of EGBS to be a bridge to surgery and a surgical alternative for acute calculus cholecystitis in patients with contraindications to early cholecystectomy.

Should the severity of acute cholecystitis (Tokyo 2018 guideline) affect the decision of early or delayed cholecystectomy?

BACKGROUND: In our study, we aimed to compare the complication rates of patients presenting with acute cholecystitis and undergoing surgery at the time of hospitalization (early cholecystectomy) and delayed cholecystectomy and also to examine whether the severity of cholecystitis has an effect on the timing of cholecystectomy. METHODS: The study was planned retrospectively and the approval of the ethics committee of our hospital was obtained. The patient files of the patients who were admitted to our tertiary hospital with acute cholecystitis were accessed through the hospital archive system. The patients were divided into two groups, those who were admitted to the emergency department for acute chole-cystitis and who underwent early cholecystectomy and delayed cholecystectomy. The Tokyo 2018 acute cholecystitis guideline was used to determine the severity of acute cholecystitis. Pre-operative and post-operative data of the patients were examined and their complications were evaluated. RESULTS: The data of 158 patients who met the inclusion criteria were retrospectively analyzed. Compared with delayed chole-cystectomy, complication rates increased in patients who underwent early cholecystectomy (8.1% and 32.2%, respectively, p<0.001). According to the Tokyo 2018 guideline, patients with acute cholecystitis were grouped as Tokyo 1, 2, and 3; and of Tokyo 1 patients, more complications were observed in those who underwent early cholecystectomy (22.6% and 4.2%, respectively, p=0.004). When the complications were examined, it was observed that pulmonary embolism, pneumonia, intra-abdominal abscess development, sepsis, and wound infection were significantly higher in those who were operated early. When the factors affecting complications are examined, having a Tokyo score of 2 and above (OR: 4.161), high creatinine levels (OR: 5.496), and presence of additional disease (OR: 4.238) increase the risk of developing complications. CONCLUSION: More complications occur after cholecystectomy in patients with Tokyo 2 and above, when compared with patients with Tokyo 1. It was observed that more complications developed in patients with Tokyo 1 cholecystitis who were operated in the early period. Further studies are needed to determine the effect of acute cholecystitis severity in determining the timing of cholecystectomy.

Surgery for acute cholecystitis in severely comorbid patients: a population-based study on acute cholecystitis.

BACKGROUND: International guidelines recommend emergency cholecystectomy for acute cholecystitis in patients who are healthy or have mild systemic disease (ASA1-2). Surgery is also an option for patients with severe systemic disease (ASA3) in clinical practice. The study aimed to investigate the risk of complications in ASA3 patients after surgery for acute cholecystitis. METHOD: 1 634 patients treated for acute cholecystitis at three Swedish centres between 2017 and 2020 were included in the study. Data was gathered from electronic patient records and the Swedish registry for gallstone surgery, Gallriks. Logistic regression was used to assess the risk of complications adjusted for confounding factors: sex, age, BMI, Charlson comorbidity index, cholecystitis grade, smoking and time to surgery. RESULTS: 725 patients had emergency surgery for acute cholecystitis, 195 were ASA1, 375 ASA2, and 152 ASA3. Complications occurred in 9% of ASA1, 13% of ASA2, and 24% of ASA3 patients. There was no difference in 30-day mortality. ASA3 patients stayed on average 2 days longer after surgery. After adjusting for other factors, the risk of complications was 2.5 times higher in ASA3 patients than in ASA1 patients. The risk of complications after elective surgery was 5% for ASA1, 13% for ASA2 and 14% for ASA3 patients. Regardless of ASA 18% of patients treated non-operatively had a second gallstone complication within 3 months. CONCLUSION: Patients with severe systemic disease have an increased risk of complications but not death after emergency surgery. The risk is lower for elective procedures, but a substantial proportion will have new gallstone complications before elective surgery. TRIAL REGISTRATION: Not applicable.
