Benefits and risks of using laparoscopic ultrasonography versus intraoperative cholangiography during laparoscopic cholecystectomy for gallstone disease: a systematic review and meta-analysis.

BACKGROUND: Intraoperative laparoscopic ultrasonography (LUS) or intraoperative cholangiography (IOC) can be used for visualisation of the biliary tract during laparoscopic cholecystectomy. The aim of this systematic review was to compare use of LUS with IOC. METHODS: PubMed, Embase, the Cochrane Library, and Web of Science were searched (last update: April 2024). PICO: P = patients undergoing intraoperative imaging of the biliary tree during laparoscopic cholecystectomy for gallstone disease; I = intervention: LUS; C = comparison: IOC; O = outcomes: mortality, bile duct injury, retained gallstone, conversion to open cholecystectomy, procedural failure, operation time including imaging time. Included articles were critically appraised using checklists. Conclusions were based on studies without major risk of bias. Meta-analyses were performed using random effects models. Certainty of evidence was assessed according to GRADE. RESULTS: Sixteen non-randomised studies met the PICO. Two before/after studies (594 versus 807 patients) contributed to conclusions regarding mortality (no events; very low certainty evidence), bile duct injury (1 versus 0 events; very low certainty evidence), retained gallstone (2 versus 2 events; very low certainty evidence), and conversion to open cholecystectomy (6 versus 21 events; risk ratio: 0.38 (95% confidence interval: 0.15-0.95); I2 = 0%; low certainty evidence). Seven additional studies, using intra-individual comparisons, contributed to conclusions regarding procedural failure; risk ratio: 1.12 (95% confidence interval: 0.70-1.78; I2 = 83%; very low certainty evidence). No studies reported operation time. Mean imaging time for LUS and IOC, reported in 12 studies, was 4.8‒10.2 versus 10.9‒17.9 min (mean difference: - 7.8 min (95% confidence interval: - 9.3 to - 6.3); I2 = 95%; moderate certainty evidence). CONCLUSION: It is uncertain whether there is any difference in mortality/bile duct injury/retained gallstone using LUS compared with IOC, but LUS may be associated with fewer conversions to open cholecystectomy and is probably associated with shorter imaging time.

Association Between Gallstone Disease and Risk of Mortality of Cardiovascular Disease and Cancer: A Systematic Review and Meta-Analysis.

BACKGROUND: Gallstone disease (GD) is increasing in the world and has various complications. OBJECTIVE: This study aims to examine the relationship between GD and the risk of mortality from cardiovascular disease (CVD) and cancer using a systematic review and meta-analysis approach. METHODS: A comprehensive and systematic search was done in various databases, such as Web of Science (WOS), Scopus, MEDLINE/PubMed, Cochrane, and Embase. The search included studies published from 1980 to December 2023. Heterogeneity was assessed using Chi-square, I2, and forest plots, while publication bias was evaluated through Begg's and Egger's tests. All analyses were performed using Stata 15, with statistical significance set at p <0.05. RESULTS: A pooled analysis of five studies involving 161,671 participants demonstrated that individuals with GD had a significantly higher risk of mortality from CVD (RR 1.29, 95% CI: 1.11-1.50, p <0.001). Importantly, no evidence of publication bias was found based on the results of Begg's test (p =0.806) and Egger's test (p =0.138). Furthermore, the pooled analysis of seven studies, encompassing a total of 562,625 participants, indicated an increased risk of cancer mortality among individuals with GD (RR 1.45, 95% CI: 1.16-1.82, p <0.001). Similarly, no publication bias was detected through Begg's test (p =0.133) and Egger's test (p =0.089). CONCLUSION: In this study, the evidence of a significant association between GD and an elevated risk of mortality from CVD and canceris provided. These findings suggest that implementing targeted interventions for individuals with gallstone disease could reduce mortality rates among these patients.

Outcomes of cholecystectomy in US veterans with cirrhosis: Predicting outcomes using nomogram.

BACKGROUND: This study examines the outcomes of open and laparoscopic cholecystectomy (OC/LC) in veterans with cirrhosis and develops a nomogram to predict outcomes. METHODS: We analyzed the Veterans Affairs Surgical Quality Improvement Program to identify all patients with cirrhosis and ascites who underwent cholecystectomy from 2008 to 2015. Univariate and multivariate regression were used to identify predictors of morbidity and mortality. A predictive nomogram was constructed and internally validated. RESULTS: A total of 349 patients were identified. Overall, complications occurred in 18.7% of patients, and mortality was 3.8%. LC was performed in 58.9%, and 19.2% were preformed emergently. Overall, Model for End-Stage Liver Disease score was an independent factor of morbidity and mortality, while laparoscopic approach had a protective effect on morbidity. CONCLUSIONS: Although cholecystectomy is a high-risk operation in cirrhotic veterans, LC may have favorable outcomes than OC in selected patients. An easy-to-use nomogram to predict morbidity and mortality for cirrhotic patients undergoing cholecystectomy is proposed.

Is endoscopic sphincterotomy beneficial for the treatment of acute gallstone pancreatitis with small bile duct stone?

BACKGROUND: Acute gallstone pancreatitis occurs when a gallstone is impacted at the ampulla of Vater. The role of endoscopic retrograde cholangiopancreatography in the treatment of small choledocholithiasis in these patients is uncertain. The aim of this study was to compare outcomes of expectant management with endoscopic sphincterotomy for the treatment of small choledocholithiasis (≤5 mm) in patients with acute gallstone pancreatitis. PATIENTS AND METHODS: Of the 258 patients admitted for acute gallstone pancreatitis from January 2010 to December 2014, 174 patients with small choledocholithiasis were reviewed retrospectively. Patients with coexisting acute cholangitis and/or pancreatobiliary malignancy were excluded. They were divided into an endoscopic sphincterotomy group (n=64) and an expectant management group (n=110). Severity index and outcomes of pancreatitis, complications, and overall mortality were compared. RESULTS: Age and sex were not significantly different between the two groups. The mean Ranson, acute physiology and chronic health evaluation-II, and bedside index of severity in acute pancreatitis scores were not significantly different between the two groups. The computed tomography severity index score was significantly higher in the expectant management group than in the endoscopic sphincterotomy group (1.6±1.1 vs. 1.0±0.9, P<0.001). Duration of hospitalization, time for normalization of the white blood cell count, and time for oral feeding were similar in both groups. There was no significant difference between two groups in the incidence of development of pseudocyst or walled-off necrosis. In addition, no difference was observed in the rate of recurrence of acute pancreatitis and readmission because of recurrent choledocholithiasis. CONCLUSION: Expectant management seems to be effective for the treatment of patients with acute gallstone pancreatitis and size of bile duct stones equal to or less than 5 mm.

Gallstone disease and increased risk of mortality: Two large prospective studies in US men and women.

BACKGROUND AND AIM: Gallstone disease has been related to a higher prevalence and incidence of chronic conditions, such as dyslipidemia, obesity, and cardiovascular disease (CVD). However, limited data are available regarding whether gallstone disease is related to mortality. METHODS: We examined the relationship of a history of gallstone disease and risk of death, using Cox proportional hazards regression analysis, among 86 030 women from the Nurses' Health Study and 43 949 men from the Health Professionals Follow-up Study. RESULTS: During the up-to 32 years of follow-up, 34 011 all-cause deaths were confirmed, of which 8138 were CVD deaths and 12 173 were cancer deaths. For the participants with a history of gallstone disease compared with those without, the hazard ratio of total mortality was 1.16 (95% confidence interval 1.13, 1.20), of CVD mortality 1.11 (1.05, 1.17), of cancer mortality 1.15 (1.09, 1.20), and of other mortality 1.19 (1.14, 1.25) from a pooled-analysis of women and men (all P < 0.001). The multi-adjusted associations between gallstone disease and total mortality persisted among women and men, and among participants with various risk profiles including the different status of body mass index, hormone therapy use, diabetes, hypertension, and hypercholesterolemia (all P for interaction ≥ 0.09). CONCLUSION: These data suggest that gallstone disease is associated with a higher risk of total mortality and disease-specific mortality, including CVD and cancer mortality, independent of various traditional risk factors.

How Safe is Performing Cholecystectomy in the Oldest Old? A 15-year Retrospective Study from a Single Institution.

BACKGROUND: Globally, the number of people aged 80 years or over, the "oldest old," is the fastest growing population group. Because of the strong association between age and gallstone disease, both prevalence and incidence of this disease are increasing. The feasibility of the cholecystectomy in octogenarians has been evaluated in several studies that confirmed the safety of the operation. However, the safety of this procedure in nonagenarians is still controversial. The aim of this study was to evaluate the safety of cholecystectomies in nonagenarians and identify related predictors for postoperative hospital length of stay (LOS) and in-hospital mortality up to 30 days postoperatively. METHODS: More than 500 cholecystectomies, both open and laparoscopic, were performed between January 2000 and September 2015 at our institution in patients 80 years and older. These statistics include both elective and emergent admissions. A retrospective review of charts over the last 15 years was conducted to compare mortality and length of postoperative stay among two patient groups: 319 octogenarians and 36 nonagenarians. Parameters evaluated include demographics, surgical presentation, American Society of Anesthesiologists (ASA) score, main diagnosis, comorbidities, type of surgery performed, LOS and in-hospital mortality. All data were analyzed with STATA (v.13) software, using a multivariate logistic regression after determining the statistically significant variables through a stepwise regression. CONCLUSIONS: We found out that being nonagenarian, compared to octogenarian, is not a significant risk factor in terms of LOS and in-hospital mortality within 30 days postoperatively. Despite that, the mortality rate among nonagenarians is still remarkably high as almost every patient was admitted in an emergent setting. The most remarkable predictor for mortality among the two groups was an "afternoon/night emergency" surgical presentation (OR 25.5, CI 1.53-42.35, p = 0.02). Thus, the surgical emergency management for gallbladder disease at our institution should be critically reevaluated. Performing the procedure in laparoscopy predicted a significant reduction (-5 days, CI -8.5 to -1.4, p = 0.006) of LOS, while presenting with "gallbladder and bile duct stones" (+6.3 days, CI 1.5-11.1, p = 0.01) or "acalculous cholecystitis" (+4.7 days, CI 0.4-9.2, p = 0.03) had the opposite effect. Despite the remarkable mortality rate of our series, being nonagenarian should not be considered as a reason to avoid gallbladder surgery in case of need. Our study suggests that nonagenarians are more suitable surgical candidates than may have previously expected.

Outcomes of Gallstone Disease during Pregnancy: a Population-based Data Linkage Study.

BACKGROUND: Gallstone disease is a leading indication for non-obstetric abdominal surgery during pregnancy. There are limited whole population data on maternal and neonatal outcomes. This population-based study aims to describe the outcomes of gallstone disease during pregnancy in an Australian setting. METHODS: Linked hospital, birth, and mortality data for all women with singleton pregnancies in New South Wales, Australia, 2001-2012 were analysed. Exposure of interest was gallstone disease (acute biliary pancreatitis, gallstones with/without cholecystitis). Outcomes including preterm birth (spontaneous and planned), readmission, morbidity and mortality (maternal and neonatal) were compared between pregnancies with and without gallstone disease. Adjusted risk ratios (aRRs) and 99% confidence intervals were estimated using modified Poisson regression and adjusted for maternal and pregnancy factors. RESULTS: Among 1 064 089 pregnancies, 1882 (0.18%) had gallstone disease. Of these, 239 (12.7%) had an antepartum cholecystectomy and 1643 (87.3%) were managed conservatively. Of those managed conservatively, 319 (19.0%) had a postpartum cholecystectomy. Gallstone disease was associated with increased risk of preterm birth (aRR 1.3, 99% CI 1.1, 1.6), particularly planned preterm birth (aRR 1.6, 99% CI 1.2, 2.1), maternal morbidity (aRR 1.6, 99% CI 1.1, 2.3), maternal readmission (aRR 4.7, 99% CI 4.2, 5.3), and neonatal morbidity (aRR 1.4, 99% CI 1.1, 1.7). Surgery was associated with decreased risk of maternal readmission (aRR 0.4, 99% CI 0.2, 0.7). CONCLUSIONS: Gallstone disease during pregnancy was associated with adverse maternal and neonatal outcomes. Most women with gallstone disease during pregnancy are managed conservatively. Surgical management was associated with decreased risk of readmission.

Expectant management of gallbladder stones after endoscopic removal of common bile duct stones.

BACKGROUND: Wait-and-see policy after endoscopic sphincterotomy (ES) for common bile duct (CBD) stones in patients with concomitant gallbladder stones may lead to recurrent biliary complications. The aim of this study was to assess the short and long-term results of wait-and-see policy in patients with intact gallbladder after endoscopic clearance of CBD stones. MATERIALS AND METHODS: From January 1999 to December 2014 a total of 181 consecutive patients with intact gallbladder underwent ES for CBD stones. The main measures of outcome were long-term biliary complications, biliary related mortality, CBD stone recurrence and need for surgical interventions. Secondary outcomes were 30-day mortality and 30-day morbidity. Clinical data were retrospectively collected from hospital records and from the National Registry of Death. RESULTS: During the median follow-up of 3.9 years (IQR 1.6-6.6) late biliary complications were observed in 24 (13.8%) patients. Cumulative biliary related morbidity at 3 and 5 years was 7.6% and 10.8%, respectively. CBD stone recurrence was observed in 9 (5.2%) patients. On-demand cholecystectomy was performed in 6 (3.3%) patients. 30-day mortality was 3.9% and 30-day morbidity 9.4%. Overall cumulative mortality rate at 3 and 5 years after ES was 31.4% and 49.7%, respectively. Long-term biliary related mortality was 1.7%. No significant difference in long term complications or biliary mortality was observed between patients< 75 or ≥75 years of age. CONCLUSION: Prophylactic cholecystectomy after ES has been shown to reduce mortality even in high-risk patients. In our series late biliary related mortality and morbidity were relatively low, because a considerable number of patients died from non-biliary related causes.However, most biliary-related events seem to occur evenly during the follow-up after ES. A prompt risk assesment and consideration of surgical treatment during index admission may prevent late biliary -related complications.

Outcome Analysis of Patients with Gallstone Disease Receiving Cholecystectomy: A Population-Based Cohort Study.

BACKGROUND/AIMS: Cholecystectomy is generally performed to treat patients with gallstone disease (GSD) in clinical practice. The present study aimed to investigate whether type 2 diabetes mellitus (T2DM) may influence the overall survival of GSD patients. METHODS: The National Health Insurance Research Database, a population-based registry data in Taiwan, was used to identify GSD patients from 2001 to 2008. The risk of cancers and effects of T2DM on the overall survival of GSD patients receiving cholecystectomy were estimated by hazards ratios (HRs) and 95% CIs using the Cox proportional hazard model. RESULTS: Among 392,028 eligible GSD patients, 81,971 underwent cholecystectomy, whereas 310,057 did not. After cholecystectomy, the HR for developing cancer was 1.14. The HR for the overall survival was 0.74-fold lower for patients who underwent cholecystectomy than that for patients who did not. GSD patients without T2DM who underwent cholecystectomy (0.78-fold lower risk) had a longer survival, whereas those with T2DM had shorter survival (1.64-fold higher risk without cholecystectomy and 1.13-fold higher risk with cholecystectomy) compared with those without T2DM who did not undergo cholecystectomy. CONCLUSIONS: Our major findings suggest that T2DM may worsen the prognosis of GSD patients after cholecystectomy, which provides useful insight into the treatment of T2DM among GSD patients in clinical settings.

Gallstone disease and mortality: a cohort study.

OBJECTIVES: The objective of this cohort study was to determine whether subjects with gallstone disease identified by screening of a general population had increased overall mortality when compared to gallstone-free participants and to explore causes of death. METHODS: The study population (N = 5928) was examined 1982-1992 and included an abdominal ultrasound examination to assess gallstone status, a physical examination, blood samples, and a questionnaire about medical history. Participants were followed up through national registers until 2015. Multiple adjusted Cox regression models were built. RESULTS: Gallstone disease was present in 10%. Mortality was 46% during median 24.7 years of follow-up with 1% lost. Overall mortality and death from cardiovascular diseases were significantly associated to gallstone disease. Death from unknown causes was significantly associated to gallstone disease and death from cancer and gastrointestinal disease was not associated. No differences in mortality for ultrasound-proven gallstones or cholecystectomy were identified. CONCLUSIONS: Gallstone disease is associated with increased overall mortality and to death from cardiovascular disease. Gallstones may be considered a possible cardiometabolic risk factor. Other unknown factors also seem to play a role.

Timing of cholecystectomy following endoscopic sphincterotomy: a population-based study.

BACKGROUND: Choledocholithiasis is commonly treated initially with endoscopic sphincterotomy, followed by cholecystectomy to definitively address the underlying problem of cholelithiasis. While the benefits of early cholecystectomy have been realized in other populations, the preferred timing for this subset of patients is less well established. We performed a large, population-based analysis to determine the frequency, benefits, and practice variance in regard to early cholecystectomy on a provincial level. METHODS: Patients undergoing endoscopic sphincterotomy followed by cholecystectomy in British Columbia, Canada, from January 2001 to December 2011 were identified using fee-code billing data. Multiple databases were linked to obtain information on demographics, admissions, procedures, mortality, and census geographic data. Regression analysis was performed for length of stay (LOS) and additional procedures. Outcome data were risk adjusted for age, gender, comorbidities, socioeconomic status, and year of procedure. Variability of early cholecystectomy crude rates across census areas was determined using a funnel plot. RESULTS: There were 4287 eligible patients. Of these, 1905 (44.4%) underwent early cholecystectomy, defined as surgery within 14 days of sphincterotomy. Median interval to cholecystectomy was 2 days for the early cholecystectomy group and 61 days for delayed. There was a significant difference in hospital LOS favoring early cholecystectomy for patients with documented gallstone disease (p < 0.05). Patients initially admitted to a surgical service were more likely to undergo early cholecystectomy (60 vs. 36%, p < 0.001). There was no difference between groups in terms of bile duct injury or mortality. There was wide variability in rates of early cholecystectomy among census areas (range 0-96%) and health regions (range 20-66%) which was not explained by population density or geography. CONCLUSION: Early cholecystectomy is the ideal approach to gallstone disease post-sphincterotomy. Despite this, a large amount of clinical variance exists in regard to timing of cholecystectomy which seems to be primarily institution dependent.

Timing of cholecystectomy in acute biliary pancreatitis: is it still reasonable to wait?

BACKGROUND: Acute gallstone-related pancreatitis is a potentially life-threatening condition, and its adequate therapy is represented by cholecystectomy. The aim of this study was to analyze the best surgical strategy, and the optimal timing. METHODS: All cases of acute pancreatitis of biliary origin occurred between January 2007 and December 2013 in Gradenigo Hospital (Turin, Italy) undergone to a surgical procedure, were reviewed. Patients were divided in two groups, based on the timing of cholecystectomy, and compared. RESULTS: Out of 2233 cholecystectomies performed in the mentioned time interval, we have identified 79 patients that fulfill the selection criteria. 24 patients were treated with an index-stay procedure, while 55 with a delayed approach. Length of stay was significantly lower in patients that underwent to an early laparoscopic cholecystectomy (9 vs. 13 days, P=0.003), while no differences were found in terms of length of intervention, intraoperative complications, postoperative stay and mortality. Patients treated with delayed surgery had a 28.6% recurrence rate of acute pancreatitis, with an odds ratio of 10.28 (P=0.02). CONCLUSIONS: Early laparoscopic cholecystectomy should be performed in suitable patients in the index admission, reducing overall risks, avoiding or at least minimizing recurrencies, and rationalizing the scarce economic resources.

Association of Cytochrome-17 (MspA1) Gene Polymorphism with Risk of Gall Bladder Stones and Cancer in North India.

BACKGROUND: Cholelithiasis is associated in 54%-98% of patients with carcinoma of the gallbladder, and a high incidence among females suggests a role of female hormones in the etiology of the disease. Cytochrome P450C17α (CYP-17) is a key enzyme involved in estrogen metabolism and polymorphisms in CYP-17 are associated with altered serum levels of estrogens. Thus, we investigated whether the CYP-17 MspA1 gene polymorphism might impact on risk of gall bladder cancers or gallstones, as well as to determine if this gene polymorphism might be linked with estrogen serum levels and lipid profile among the North Indian gall bladder cancer or gallstone patients. MATERIALS AND METHODS: CYP-17 gene polymorphisms (MspA1) were genotyped with PCR-RFLP in cancer patients (n=96), stone patients (n=102), cancer+stone patients (n=52) and age/sex matched control subjects (n=256). Lipid profile was estimated using a commercial kit and serum estrogen was measured using ELISA. RESULTS: The majority of the patients in all groups were females. The lipid profile and estrogen level were significantly higher among the study as compared to control groups. The frequency of mutant allele A2 of CYP17 MspA1 gene polymorphism was higher among cancer (OR=5.13, 95% CI+3.10-8.51, p=0.0001), stone (OR=5.69, 95%CI=3.46-9.37, p=0.0001) and cancer+stone (OR=3.54, 95%CI=1.90-6.60, p=0.0001) when compared with the control group. However there was no significant association between genotypes of CYP17 MspA1 gene polymorphism and circulating serum level of estrogen and lipid profile. CONCLUSIONS: A higher frequency of mutant genotype A1A2 as well as mutant allele A2 of CYP-17 gene polymorphism is significantly associated with risk of gallbladder cancer and stones. Elevated levels of estrogen and an altered lipid profile can be used as predictors ofgall bladder stones and cancer in post menopausal females in India.

Recurrence of biliary disease following non-operative management in elderly patients.

INTRODUCTION: The purpose of this study was to determine the proportion of symptomatic recurrence following initial non-operative management of gallstone disease in the elderly and to test possible predictors. METHODS: This is a single institution retrospective chart review of patients 65 years and older with an initial hospital visit (V1) for symptomatic gallstone disease, over a 4-year period. Patients with initial "non-operative" management were defined as those without surgery at V1 and without elective surgery at visit 2 (V2). Baseline characteristics included age, sex, Charlson comorbidity index (CCI), diagnosis, and interventions (ERCP or cholecystostomy) at V1. Outcomes assessed over 1 year were as follows: recurrence (any ER/admission visit following V1), surgery, complications, and mortality. A survival analysis using a Cox proportional hazards model was performed to assess predictors of recurrence. RESULTS: There were 195 patients initially treated non-operatively at V1. Mean age was 78.3 ± 7.8 years, 45.6% were male, and the mean CCI was 2.1 ± 1.9. At V1, 54.4% had a diagnosis of biliary colic or cholecystitis, while 45.6% had a diagnosis of cholangitis, pancreatitis, or choledocholithiasis. 39.5% underwent ERCP or cholecystostomy. Excluding 10 patients who died at V1, 31.3% of patients had a recurrence over the study period. Among these, 43.5% had emergency surgery, 34.8% had complications, and 4.3% died. Median time to first recurrence was 2 months (range 6 days-4.8 months). Intervention at V1 was associated with a lower probability of recurrence (HR 0.3, CI [0.14-0.65]). CONCLUSION: One-third of elderly patients will develop a recurrence following non-operative management of symptomatic biliary disease. These recurrences are associated with significant rates of emergency surgery and morbidity. Percutaneous or endoscopic therapies may decrease the risk of recurrence.

Common bile duct exploration in an elderly Asian population.

Common bile duct exploration (CBDE) is an accepted treatment for choledocholithiasis. This procedure is not well studied in the elderly population. Here we evaluate the results of CBDE in elderly patients (>70 years) and compare the open (group A) with the laparoscopic group (group B). A retrospective review was performed of elderly patients with proven common bile duct (CBD) stones who underwent CBDE from January 2005 to December 2009. There were 55 patients in group A and 33 patients in group B. Mean age was 77.6 years (70-91 years). Both groups had similar demographics, liver function tests, and stone size-12 mm (range, 5-28 mm). Patients who had empyema (n = 9), acute cholecystitis (n = 15), and those who had had emergency surgery (n = 28) were more likely to be in group A (P < 0.05). The mean length of stay for group A was 11.7 ± 7.3 days; for group B, 5.2 ± 6.3 days; the complication rate was higher in group A (group A, 38.2%; group B, 8.5%; P = 0.072). The overall complication and mortality rate was 29.5% and 3.4%, respectively. CBDE can be performed safely in the elderly with accepted morbidity and mortality. The laparoscopic approach is feasible and safe in elective setting even in the elderly.

Long-term outcomes of laparoscopic gastrectomy for gastric cancer.

BACKGROUND: Laparoscopic gastrectomy (LG) has been established as a procedure for the treatment of gastric cancer. However, there have been few reports on the long-term outcomes of LG for gastric cancer. The aim of this study is to investigate the long-term outcomes of LG for gastric cancer. METHODS: A total of 278 consecutive patients who underwent LG in our unit between January 1999 and December 2006 were included in this study. Survival, recurrence, and late gastrointestinal complications were analyzed. RESULTS: The median follow-up period was 73.7 mo (6-165 mo). Distal gastrectomy was performed in 229 patients, total gastrectomy in 23 patients, proximal gastrectomy in 15 patients, and pylorus-preserving gastrectomy in 11 patients. Five-year overall and disease-specific survival rates were 91% and 99% for stage IA, 75% and 91% for stage IB, 72% and 88% for stage II, and 40% and 50% for stage III, respectively. Recurrences were detected in 15 (5.4%) patients, including 5 distant lymph node, 5 peritoneal, 4 hematogenous, and 1 locoregional recurrences. Bowel obstruction occurred in 4 (1.4%) patients, and gallstones developed in 37 (15%) patients. CONCLUSIONS: This follow-up investigation suggested that LG for gastric cancer is a feasible procedure from the standpoint of long-term oncological outcome and postoperative complications.

Surgery for gallstone ileus: a nationwide comparison of trends and outcomes.

INTRODUCTION: Gallstone ileus is a mechanical bowel obstruction caused by a biliary calculus originating from a bilioenteric fistula. Because of the limited number of reported cases, the optimal surgical method of treatment has been the subject of ongoing debate. METHODS: A retrospective review of the Nationwide Inpatient Sample from 2004 to 2009 was performed for gallstone ileus cases treated surgically by enterotomy with stone extraction alone (ES), enterotomy and cholecystectomy with fistula closure (EF), bowel resection alone (BR), and bowel resection with fistula closure (BF). Patient demographics, hospital factors, comorbidities, and postoperative outcomes were reported. Multivariate analysis was performed comparing mortality, morbidity, length of stay, and total cost for the different procedure types. RESULTS: Of the estimated 3,452,536 cases of mechanical bowel obstruction from 2004 to 2009, 3268 (0.095%) were due to gallstone ileus-an incidence lower than previously reported. The majority of patients were elderly women (>70%). ES was the most commonly performed procedure (62% of patients) followed by EF (19% of cases). In 19%, a bowel resection was required. The most common complication was acute renal failure (30.44% of cases). In-hospital mortality was 6.67%. On multivariate analysis, EF and BR were independently associated with higher mortality than ES [(odds ratio [OR] = 2.86; confidence interval [CI]: 1.16-7.07) and (OR = 2.96; CI: 1.26-6.96) respectively]. BR was also associated with a higher complication rate, OR = 1.98 (CI: 1.13-3.46). CONCLUSIONS: Gallstone ileus is a rare surgical disease affecting mainly the elderly female population. Mortality rates appear to be lower than previously reported in the literature. Enterotomy with stone extraction alone appears to be associated with better outcomes than more invasive techniques.

A laparoscopic approach to CBD stones.

AIM: : This study aimed to evaluate single-stage surgical (laparoscopic or open) approach to the management of common bile duct (CBD) stones, as treatment of choice. METHODS: Prospectively collected data to assess outcomes of CBD clearance, morbidity, mortality, and hospital stay, and compared with published data. RESULTS: Successful clearance of CBD stones was achieved in 96% cases, laparoscopic exploration successful in 83%. Retained stones were found in 4% cases and another 5% developed postoperative complications. Common length of stay in hospital was 2 days, although mean stay was 4 days. Seventy-three percent of cases were elective, 27% were emergencies. Conversion rate to open surgery was 14%, which was mainly in emergency cases. Postoperative mortality was 1.2%, not directly related to the procedure. CONCLUSIONS: Good outcomes can be achieved, comparing favorably with those of other modalities, when laparoscopic bile duct exploration is chosen as treatment for CBD stones; the best results can be anticipated in elective patients.

Gallstone ileus: revisiting surgical outcomes using National Surgical Quality Improvement Program data.

BACKGROUND: Although surgical management remains the mainstay of therapy for gallstone ileus, the optimal approach--enterolithotomy alone or combined with biliary-enteric fistula disruption--is controversial because of the reliance on small single-center series to describe outcomes. Using the American College of Surgeons' National Surgical Quality Improvement Program database, we sought to (1) review the outcomes of patients undergoing surgical management of gallstone ileus and (2) determine if cholecystectomy in addition to enterolithotomy increased morbidity or mortality rate. METHODS: We analyzed the demographics, comorbidities, acuity, operative time, postoperative hospitalization length, and 30-d morbidity and mortality rates of 127 patients from 2005 to 2010 who underwent a procedure for the relief of gallstone ileus. We identified a subset of 14 patients who underwent simultaneous cholecystectomy. We compared the "no cholecystectomy" and "cholecystectomy" groups using standard statistical methods. RESULTS: The overall 30-d postoperative morbidity and mortality rate was 35.4% and 5.5%, respectively. Superficial surgical site infection and urinary tract infection were the most common complications. There was no significant difference in mortality rate between the no cholecystectomy and the cholecystectomy groups (5.3% versus 7.1%, respectively; P = 0.78), but the latter group did experience more minor complications, longer operations, and longer postoperative hospitalization. CONCLUSIONS: Other recent studies on this topic have collected data or reviewed literature across several decades, making this study in particular one of the largest truly modern series. Perhaps reflecting changes in perioperative management, surgical treatment of gallstone ileus is less morbid than previously described, but there is still insufficient evidence to favor concurrent cholecystectomy.
