RESUMO
INTRODUCTION: Racial and ethnic disparities in emergency general surgery (EGS) patients have been well described in the literature. Nonetheless, the burden of these disparities, specifically within the more vulnerable older adult population, is relatively unknown. This study aims to investigate racial and ethnic disparities in clinical outcomes among older adult patients undergoing EGS. METHODS: This retrospective analysis used data from 2013 to 2019 American College of Surgeons National Surgery Quality Improvement Program database. EGS patients aged 65 y or older were included. Patients were categorized based on their self-reported race and ethnicity. The primary outcomes evaluated were in-hospital mortality, 30-d mortality, and overall morbidity. Multivariable logistic regression was performed to examine the relationship between race/ethnicity and postoperative outcomes while adjusting for relevant factors including age, comorbidities, functional status, preoperative conditions, and surgical procedure. RESULTS: A total of 54,132 patients were included, of whom 79.8% identified as non-Hispanic White, 9.5% as non-Hispanic Black (NHB), 5.8% as Hispanic, and 4.2% as non-Hispanic Asian. After risk adjustment, compared to non-Hispanic White patients, NHB, non-Hispanic Asian, and Hispanic patients had decreased odds of 30-d mortality. For 30-d readmission and reoperation, differences among groups were comparable. However, NHB patients had significantly increased odds of overall morbidity (adjusted odds ratio, 1.18; 95% confidence interval: 1.10-1.26; P < 0.001) and postoperative complications including sepsis, venous thromboembolism, and unplanned intubation. Hispanic ethnicity was associated with lower odds of postoperative myocardial infarction and stroke. CONCLUSIONS: Among older adult patients undergoing emergency general surgery, minority patients experienced higher morbidity rates, but paradoxical disparities in mortality were detected. Further research is necessary to identify the cause of these disparities and develop targeted interventions to eliminate them.
RESUMO
INTRODUCTION: General surgery procedures place stress on geriatric patients, and postdischarge care options should be evaluated. We compared the association of discharge to a skilled nursing facility (SNF) versus home on patient readmission. METHODS: We retrospectively reviewed the Nationwide Readmission Database (2016-2019) and included patients ≥65 y who underwent a general surgery procedure between January and September. Our primary outcome was 30-d readmissions. Our secondary outcome was predictors of readmission after discharge to an SNF. We performed a 1:1 propensity-matched analysis adjusting for patient demographics and hospital course to compare patients discharged to an SNF with patients discharged home. We performed a sensitivity analysis on patients undergoing emergency procedures and a stepwise regression to identify predictors of readmission. RESULTS: Among 140,056 included patients, 33,916 (24.2%) were discharged to an SNF. In the matched population of 19,763 pairs, 30-d readmission was higher in patients discharged to an SNF. The most common diagnosis at readmission was sepsis, and a greater proportion of patients discharged to an SNF were readmitted for sepsis. In the sensitivity analysis, emergency surgery patients discharged to an SNF had higher 30-d readmission. Higher illness severity during the index admission and living in a small or fringe county of a large metropolitan area were among the predictors of readmission in patients discharged to an SNF, while high household income was protective. CONCLUSIONS: Discharge to an SNF compared to patients discharged home was associated with a higher readmission. Future studies need to identify the patient and facility factors responsible for this disparity.

INTRODUCTION: Obesity is increasingly prevalent both nationwide and in the emergency general surgery (EGS) population. While previous studies have shown that obesity may be protective against mortality following EGS procedures, the association between body mass index (BMI) and postoperative outcomes, as well as intraoperative decision-making, remains understudied. METHODS: The National Surgical Quality Improvement Program 2015-2019 database was used to identify all adult patients undergoing an open abdominal or abdominal wall procedure for EGS conditions. Our outcomes included 30-d postoperative mortality, composite 30-d morbidity, delayed fascial closure, reoperation, operative time, and hospital length of stay (LOS). Multivariable logistic regression models were used to explore the association between BMI and each outcome of interest while adjusting for patient demographics, comorbidities, laboratory tests, preoperative and intraoperative variables. RESULTS: We identified 78,578 patients, of which 3121 (4%) were categorized as underweight, 23,661 (30.1%) as normal weight, 22,072 (28.1%) as overweight, 14,287 (18.2%) with class I obesity, 7370 (9.4%) with class II obesity, and 8067 (10.3%) with class III obesity. Class III obesity was identified as a risk factor for 30-d postoperative morbidity (adjusted odds ratio 1.14, 95% CI, 1.03-1.26, P < 0.01). An increase in obesity class was also associated with a stepwise increase in the risk of undergoing delayed fascial closure, experiencing a prolonged operative time, and having an extended LOS. CONCLUSIONS: Obesity class was associated with an increase in delayed fascial closure, longer operative time, higher reoperation rates, and extended hospital LOS. Further studies are needed to explore how a patient's BMI impacts intraoperative factors, influences surgical decision-making, and contributes to hospital costs.
RESUMO
INTRODUCTION: Delayed fascial closure (DFC) is an increasingly utilized technique in emergency general surgery (EGS), despite a lack of data regarding its benefits. We aimed to compare the clinical outcomes of DFC versus immediate fascial closure (IFC) in EGS patients with intra-abdominal contamination. METHODS: This retrospective study was conducted using the 2013-2020 American College of Surgeons National Surgical Quality Improvement Program database. Adult EGS patients who underwent an exploratory laparotomy with intra-abdominal contamination [wound classification III (contaminated) or IV (dirty)] were included. Patients with agreed upon indications for DFC were excluded. A propensity-matched analysis was performed. The primary outcome was 30-d mortality. RESULTS: We identified 36,974 eligible patients. 16.8% underwent DFC, of which 51.7% were female, and the median age was 64 y. After matching, there were 6213 pairs. DFC was associated with a higher risk of mortality (15.8% versus 14.2%, P = 0.016), pneumonia (11.7% versus 10.1%, P = 0.007), pulmonary embolism (1.9% versus 1.6%, P = 0.03), and longer hospital stay (11 versus 10 d, P < 0.001). No significant differences in postoperative sepsis and deep surgical site infection rates between the two groups were observed. Subgroup analyses by preoperative diagnosis (diverticulitis, perforation, and undifferentiated sepsis) showed that DFC was associated with longer hospital stay in all subgroups, with a higher mortality rate in patients with diverticulitis (8.1% versus 6.1%, P = 0.027). CONCLUSIONS: In the presence of intra-abdominal contamination, DFC is associated with longer hospital stay and higher rates of mortality and morbidity. DFC was not associated with decreased risk of infectious complications. Further studies are needed to clearly define the indications of DFC.
RESUMO
BACKGROUND: There are no prediction models for bile leakage associated with subtotal cholecystectomy (STC). Therefore, this study aimed to generate a multivariable prediction model for post-STC bile leakage and evaluate its overall performance. METHODS: We analysed prospectively managed data of patients who underwent STC by a single consultant surgeon between 14 May 2013 and 21 December 2021. STC was schematised into four variants with five subvariants and classified broadly as closed-tract or open-tract STC. A contingency table was used to detect independent risk factors for bile leakage. A multiple logistic regression analysis was used to generate a model. Discrimination and calibration statistics were computed to assess the accuracy of the model. RESULTS: A total of 81 patients underwent the STC procedure. Twenty-eight patients (35%) developed bile leakage. Of these, 18 patients (64%) required secondary surgical intervention. Multivariable logistic regression revealed two independent predictors of post-STC bile leak: open-tract STC (odds ratio [OR], 7.07; 95% confidence interval [CI], 2.191-25.89; P = 0.0170) and acute cholecystitis (OR, 5.449; 95% CI, 1.584-23.48; P = 0.0121). The area under the receiver-operating characteristic curve was 82.11% (95% CI, 72.87-91.34; P < 0.0001). Tjur's pseudo-R2 was 0.3189 and the Hosmer-Lemeshow goodness-of-fit statistic was 4.916 (P = 0.7665). CONCLUSIONS: Open-tract STC and acute cholecystitis are the most reliable predictors of bile leakage associated with STC. Future prospective, multicentre studies with higher statistical power are needed to generate more specific and externally validated prediction models for post-STC bile leaks.

BACKGROUND: Emergent surgical conditions are common in geriatric patients, often necessitating major operative procedures on frail patients. Understanding risk profiles is crucial for decision-making and establishing goals of care. METHODS: We queried NSQIP 2015-2019 for patients ≥65 years undergoing open abdominal surgery for emergency general surgery conditions. Logistic regression was used to identify 30-day mortality predictors. RESULTS: Of 41,029 patients, 5589 (13.6 â%) died within 30 days of admission. The highest predictors of mortality were ASA status 5 (aOR 9.7, 95 â% CI,3.5-26.8, p â< â0.001), septic shock (aOR 4.9, 95 â% CI,4.5-5.4, p â< â0.001), and dialysis (aOR 2.1, 95 â% CI,1.8-2.4, p â< â0.001). Without risk factors, mortality rates were 11.9 â% after colectomy and 10.2 â% after small bowel resection. Patients with all three risk factors had a mortality rate of 79.4 â% and 100 â% following colectomy and small bowel resection, respectively. CONCLUSIONS: In older adults undergoing emergent open abdominal surgery, septic shock, ASA status, and dialysis were strongly associated with futility of surgical intervention. These findings can inform goals of care and informed decision-making.
RESUMO
PURPOSE: Our understanding of the growing geriatric population's risk factors for outcomes after traumatic injury remains incomplete. This study aims to compare outcomes of severe isolated blunt chest trauma between young and geriatric patients and assess predictors of mortality. METHODS: The ACS-TQIP 2017-2020 database was used to identify patients with severe isolated blunt chest trauma. Patients having extra-thoracic injuries, no signs of life upon presentation to the emergency department (ED), prehospital cardiac arrest, or who were transferred to or from other hospitals were excluded. The primary outcome was in-hospital mortality. Univariate and multivariable regression analyses were performed to assess independent predictors of mortality. RESULTS: A total of 189,660 patients were included in the study, with a median age of 58 years; 37.5% were aged 65 or older, and 1.9% died by discharge. Patients aged 65 and older had significantly higher mortality (3.4% vs. 1.0%, p < 0.001) and overall complications (7.0% vs. 4.7%, p < 0.001) compared to younger patients. Age ≥ 65 was independently associated with mortality (OR: 5.45, 95%CI: 4.96-5.98, p < 0.001), prolonged hospitalization, and complications. In the geriatric group, age > 75 was an independent predictor of mortality compared to ages 65-75 (OR: 2.62, 95%CI: 2.37-2.89, p < 0.001). Geriatric patients with an MVC, presenting with a GCS ≤ 8, and having an SBP < 90 had the highest mortality of 56.9%. CONCLUSION: The geriatric trauma patient with isolated severe blunt chest injury has significantly higher mortality and morbidity compared to younger patients and warrants special consideration of multiple factors that affect outcomes. Individual predictors of mortality carry a greater impact on mortality in geriatric patients.
RESUMO
BACKGROUND: Care fragmentation has been shown to lead to increased morbidity and mortality. We aimed to explore the factors related to care fragmentation after hospital discharge in geriatric emergency general surgery patients, as well as examine the association between care fragmentation and mortality. METHODS: We designed a retrospective study of the Nationwide Readmissions Database 2019. We included patients ≥65 years old admitted with an emergency general surgery diagnosis who were discharged alive from the index admission. The primary outcome was 90-day care fragmentation, defined as an unplanned readmission to a non-index hospital. Multivariable logistic regression was performed, adjusting for patient and hospital characteristics. RESULTS: A total of 447,027 older adult emergency general surgery patients were included; the main diagnostic category was colorectal (22.6%), and 78.2% of patients underwent non-operative management during the index hospitalization. By 90 days post-discharge, 189,622 (24.3%) patients had an unplanned readmission. Of those readmitted, 20.8% had care fragmentation. The median age of patients with care fragmentation was 76 years, and 53.2% were of female sex. Predictors of care fragmentation were living in rural counties (odds ratio 1.76, 95% confidence interval: 1.57-1.97), living in a low-income ZIP Code, discharge to intermediate care facility (odds ratio 1.28, 95% confidence interval: 1.22-1.33), initial non-operative management (odds ratio 1.17, 95% confidence interval: 1.12-1.23), leaving against medical advice (odds ratio 2.60, 95% confidence interval: 2.29-2.96), and discharge from private investor-owned hospitals (odds ratio 1.18, 95% confidence interval: 1.10-1.27). Care fragmentation was significantly associated with higher mortality. CONCLUSION: The burden of unplanned readmissions in older adult patients who survive an emergency general surgery admission is underestimated, and these patients frequently experience care fragmentation. Future directions should prioritize evaluating the impact of initiatives aimed at alleviating the incidence and complications of care fragmentation in geriatric emergency general surgery patients.

PURPOSE: Noncompressible truncal hemorrhage remains a leading cause of preventable death in the prehospital setting. Standardized and reproducible large animal models are essential to test new therapeutic strategies. However, existing injury models vary significantly in consistency and clinical accuracy. This study aims to develop a lethal porcine model to test hemostatic agents targeting noncompressible abdominal hemorrhages. METHODS: We developed a two-hit injury model in Yorkshire swine, consisting of a grade IV liver injury combined with hemodilution. The hemodilution was induced by controlled exsanguination of 30% of the total blood volume and a 3:1 resuscitation with crystalloids. Subsequently, a grade IV liver injury was performed by sharp transection of both median lobes of the liver, resulting in major bleeding and severe hypotension. The abdominal incision was closed within 60 s from the injury. The endpoints included mortality, survival time, serum lab values, and blood loss within the abdomen. RESULTS: This model was lethal in all animals (5/5), with a mean survival time of 24.4 ± 3.8 min. The standardized liver resection was uniform at 14.4 ± 2.1% of the total liver weight. Following the injury, the MAP dropped by 27 ± 8mmHg within the first 10 min. The use of a mixed injury model (i.e., open injury, closed hemorrhage) was instrumental in creating a standardized injury while allowing for a clinically significant hemorrhage. CONCLUSION: This novel highly lethal, consistent, and clinically relevant translational model can be used to test and develop life-saving interventions for massive noncompressible abdominal hemorrhage.
RESUMO
PURPOSE: For polytrauma patients with bilateral femoral shaft fractures (BFSF), there is currently no consensus on the optimal timing of surgery. This study assesses the impact of early (≤ 24 h) versus delayed (>24 h) definitive fixation on clinical outcomes, especially focusing on concomitant versus staged repair. We hypothesized that early definitive fixation leads to lower mortality and morbidity rates. METHODS: The 2017-2020 Trauma Quality Improvement Program was used to identify patients aged ≥16 years with BFSF who underwent definitive fixation. Early definitive fixation (EDF) was defined as fixation of both femoral shaft fractures within 24 h, delayed definitive fixation (DDF) as fixation of both fractures after 24 h, and early staged fixation (ESF) as fixation of one femur within 24 h and the other femur after 24 h. Propensity score matching and multilevel mixed effects regression models were used to compare groups. RESULTS: 1,118 patients were included, of which 62.8% underwent EDF. Following propensity score matching, 279 balanced pairs were formed. EDF was associated with decreased overall morbidity (12.9% vs 22.6%, p = 0.003), lower rate of deep venous thrombosis (2.2% vs 6.5%, p = 0.012), a shorter ICU LOS (5 vs 7 days, p < 0.001) and a shorter hospital LOS (10 vs 15 days, p < 0.001). When compared to DDF, early staged fixation (ESF) was associated with lower rates of ventilator acquired pneumonia (0.0% vs 4.9%, p = 0.007), but a longer ICU LOS (8 vs 6 days, p = 0.004). Using regression analysis, every 24-hour delay to definitive fixation increased the odds of developing complications by 1.05, postoperative LOS by 10 h and total hospital LOS by 27 h. CONCLUSION: Early definitive fixation (≤ 24 h) is preferred over delayed definitive fixation (>24 h) for patients with bilateral femur shaft fractures when accounting for age, sex, injury characteristics, additional fractures and interventions, and hospital level. Although mortality does not differ, overall morbidity and deep venous thrombosis rates, and length of hospital and intensive care unit stay are significantly lower. When early definitive fixation is not possible, early staged repair seems preferable over delayed definitive fixation.

BACKGROUND: Emergency general surgery performed among patients over 65 years of age represents a particularly high-risk population. Although interhospital transfer has been linked to higher mortality in emergency general surgery patients, its impact on outcomes in the geriatric population remains uncertain. We aimed to establish the effect of interhospital transfer on postoperative outcomes in geriatric emergency general surgery patients. METHODS: Emergency general surgery patients 65 years and older were identified with American College of Surgeons National Surgical Quality Improvement Program 2013 to 2019. Patients were categorized based on admission source as either directly admitted or transferred from an outside hospital inpatient unit or emergency department. The primary outcomes evaluated were in-hospital mortality, 30-day mortality, and overall morbidity. Propensity score matching was used to control for confounders, including age, race, comorbidities, and preoperative conditions. Kaplan-Meier survival analysis and the log-rank test were used to compare 30-day survival in the matched cohort. RESULTS: Among the 88,424 patients identified, 13,872 (15.7%) were transfer patients. The median age was 74, and 53% were of female sex. Transfer patients had higher rates of comorbidities and preoperative conditions, including a higher prevalence of preoperative sepsis (21.8% vs 19.3%, P < .001) and ventilator dependence (6.4% vs 2.6%, P < .001). After propensity score-matched analysis, transferred patients exhibited higher rates of in-hospital mortality, 30-day mortality, and overall morbidity. Transfer patients were also less likely to be discharged home and more likely to be discharged to an acute care facility. Kaplan-Meier survival analysis confirmed a poorer 30-day survival in transferred patients. CONCLUSION: Interhospital transfer independently contributed to overall mortality and morbidity amongst geriatric emergency general surgery patients. Further investigation into improved coordination between hospitals, tailored care plans, and comprehensive risk assessments are needed to help mitigate the observed differences in outcomes.
RESUMO
BACKGROUND: Current guidelines for sigmoid volvulus recommend endoscopy as a first line of treatment for decompression, followed by colectomy as early as possible. Timing of the latter varies greatly. This study compared early (≤2 days) versus delayed (>2 days) sigmoid colectomy. METHODS: 2016-2019 NRD database was queried to identify patients aged ≥65 years admitted for sigmoid volvulus who underwent sequential endoscopic decompression and sigmoid colectomy. Outcomes included mortality, complications, hospital length of stay, readmissions, and hospital costs. RESULTS: 842 patients were included, of which 409 (48.6 â%) underwent delayed sigmoid colectomy. Delayed sigmoid colectomy was associated with reduced cardiac complications (1.1 â% vs 0.0 â%, p â= â0.045), reduced ostomy rate (38.3 â% vs 29.4 â%, p â= â0.013), an increased overall length of stay (12 days vs 8 days, p â< â0.001) and increased overall costs (27,764 dollar vs. 24,472 dollar, p â< â0.001). CONCLUSION: In geriatric patient with sigmoid volvulus, delayed surgical resection after decompression is associated with reduced cardiac complications and reduced ostomy rate, while increasing overall hospital length of stay and costs.

BACKGROUND: Dense inflammation obscuring the hepatocystic anatomy can hinder the ability to perform a safe standard laparoscopic cholecystectomy in severe cholecystitis, requiring use of a bailout procedure. We compared clinical outcomes of laparoscopic and open subtotal cholecystectomy against the traditional standard of open total cholecystectomy to identify the optimal bailout strategy for the difficult gallbladder. METHODS: A multicenter, multinational retrospective cohort study of patients who underwent bailout procedures for severe cholecystitis. Procedures were compared using one-way analysis of variance/Kruskal-Wallis tests and χ2 tests with multiple pairwise comparisons, maintaining a family-wise error rate at 0.05. Multiple multivariate linear/logistical regression models were created. RESULTS: In 11 centers, 727 bailout procedures were conducted: 317 laparoscopic subtotal cholecystectomies, 172 open subtotal cholecystectomies, and 238 open cholecystectomies. Baseline characteristics were similar among subgroups. Bile leak was common in laparoscopic and open fenestrating subtotal cholecystectomies, with increased intraoperative drain placements and postoperative endoscopic retrograde cholangiopancreatography(P < .05). In contrast, intraoperative bleeding (odds ratio = 3.71 [1.9, 7.22]), surgical site infection (odds ratio = 2.41 [1.09, 5.3]), intensive care unit admission (odds ratio = 2.65 [1.51, 4.63]), and length of stay (Δ = 2 days, P < .001) were higher in open procedures. Reoperation rates were higher for open reconstituting subtotal cholecystectomies (odds ratio = 3.43 [1.03, 11.44]) than other subtypes. The overall rate of bile duct injury was 1.1% and was not statistically different between groups. Laparoscopic subtotal cholecystectomy had a bile duct injury rate of 0.63%. CONCLUSION: Laparoscopic subtotal cholecystectomy is a feasible surgical bailout procedure in cases of severe cholecystitis where standard laparoscopic cholecystectomy may carry undue risk of bile duct injury. Open cholecystectomy remains a reasonable option.

The role of anatomical variability in safe clinical practice is underappreciated. A lack of familiarity of anatomical variations is at the center of a multitude of medical and surgical errors. The recent rise in litigation due to such errors suggests that patient care may be compromised. This makes the knowledge of anatomical variation essential to medical education. Empirical studies were identified by searching several databases and repositories, and the Medical Education Research Quality Instrument (MERSQI) was used to assess study quality. Eight studies were eligible for this systematic review; three of which were conference abstracts. Thematic summary of these studies yielded six themes namely: (1) importance of anatomical variation in medical education; (2) the ideal time to introduce anatomical variation in medical education; (3) important anatomical variations to include in medical education; (4) approaches to teaching anatomical variation; (5) assessing knowledge on anatomical variation; (6) barriers to including anatomical variation in medical education. Including anatomical variations in medical education would improve clinical reasoning and surgical outcomes. Following the completion of this review, three recommendations were made: (1) increasing the emphasis of anatomical variation in medical education; (2) developing more resources for anatomical variation education; (3) investigating the implications of lack of knowledge of anatomical variation in medical education through further research.

Type B lactic acidosis is an uncommon medical emergency in which acid production overwhelms hepatic clearance. This specific etiology of lactic acidosis occurs without organ hypoperfusion and has been most commonly described in patients with hematologic malignancies but also in patients with solid tumors. The mechanism by which cancer cells switch their glucose metabolism toward increasingly anaerobic glycolytic phenotypes has been described as the "Warburg effect." Without treating the underlying malignancy, the prognosis for patients diagnosed with malignancy-related type B lactic acidosis is extremely poor. Here, we present a case of a 66-year-old male who was diagnosed with type B lactic acidosis secondary to mantle cell lymphoma. Bicarbonate drip was started to correct the lactic acidosis. The patient was also immediately treated with rituximab chemotherapy combined with rasburicase to avoid the hyperuricemia associated with tumor lysis syndrome. He responded to the early treatment and was discharged with normal renal function. Type B lactic acidosis secondary to hematologic malignancy is important to recognize. In order to successfully treat this syndrome, early diagnosis and simultaneous treatment of the imbalance of lactic acid levels and the underlying malignancy are necessary.
RESUMO
BACKGROUND: There are no reports on nationwide trends in subtotal cholecystectomy (STC) and cholecystostomy in England. We hypothesized that, as in the United States, a substantial increase in the utilization of these surgical procedures, over time, may be observed. We aimed to generate a reliable report on 4 of the most common gallbladder surgical procedures in England to allow cross-procedure comparisons and highlight significant changes in the management of benign gallbladder disease over time. METHODS: We obtained data from NHS Digital and extracted population estimates from the Office of National Statistics. We examined the trends in the use of STC, cholecystostomy, cholecystolithotomy and total cholecystectomy (TC) between 2000 and 2019. RESULTS: Of the 1,234,319 gallbladder surgeries performed, TC accounted for 96.8% (n = 1,194,786) and the other 3 surgeries for 3.2% (n = 39,533). The total number of gallbladder surgeries performed annually increased by 80.4% from 2000 to 2019. We detected increases in the counts of cholecystostomies by 723.1% (n = 290 in 2000 vs n = 2,387 in 2019) and STCs by 716.6% (n = 217 in 2000 vs n = 1,772 in 2019). Consequently, there was a decrease in the ratio of TC to STC (180:1 in 2000 vs 38:1 in 2019). A similar decrease was observed in the ratio of cholecystectomy to cholecystostomy (135:1 in 2000 vs 29:1 in 2019). CONCLUSION: Increased utilization of STC and cholecystostomy was detected in England. These findings highlight the importance of regular monitoring of nationwide trends in gallbladder surgery and the associated clinical outcomes.

BACKGROUND: Malignancies that spread to the lymph nodes may be identified through surgical biopsy, and treatment of metastatic disease may be through lymph node dissection. These surgeries, however, may be associated with significant adverse outcomes, particularly wound complications, the true incidence of which remains unknown. Multiple studies have reported their individual rates of complications in isolation. The aim of this study will be to systematically evaluate data that presents the incidence of wound complications in patients undergoing these surgeries. METHODS: We have designed and registered a protocol for a systematic review and meta-analysis of studies presenting incidence data. We will search MEDLINE, EMBASE and CENTRAL for relevant articles. Meta-analysis will be undertaken to synthesise an overall incidence of surgical site infection, wound dehiscence, haematoma and seroma. Subgroup analyses will investigate the effects of anatomical location, primary malignancy and study design on pooled incidence. Risk of bias will be evaluated for each included study using bespoke tools matched to the study design. DISCUSSION: The results of this study will provide the incidence of wound complications and secondary complications following lymph node surgery. This will directly impact upon the consent process, and may influence the nature of future research studies aimed at reducing post-operative complications.

BACKGROUND: Subtotal cholecystectomy is recognized as a rescue procedure performed in grossly suboptimal circumstances that would deem a total cholecystectomy too risky to execute. An earlier systematic review based on 30 studies published between 1985 and 2013 concluded that subtotal cholecystectomy had a morbidity rate comparable to that of total cholecystectomy. This systematic review appraises 17 clinical outcomes in patients undergoing subtotal cholecystectomy. METHODS: The study protocol was registered with the International Prospective Register for Systematic Reviews (CRD42020172808). MEDLINE, Embase, Cochrane bibliographic databases, and Google Scholar were used to identify papers published between 1985 and June 2020. Data related to the surgical setting, approach, intervention on the hepatic wall of the gallbladder, type of completion of subtotal cholecystectomy, year of study, and study design were collected. Seventeen clinical outcomes were considered. Meta-analyses were performed using a random-effects model, and the effect size was presented as risk ratios with 95% confidence intervals. RESULTS: From 1,017 records, 85 eligible studies were identified and included. These included 3,645 patients who underwent subtotal cholecystectomy. Laparoscopic (80.1%, n = 2,918) and reconstituting (74.6%, n = 2,719) approaches represented the majority of all subtotal cholecystectomy cases. Seven (0.2%) cases of injury to the bile duct were reported. Bile leak was reported in 506 (13.9%) patients. Reconstituting subtotal cholecystectomy was associated with a lower risk for 11 clinical outcomes. Open subtotal cholecystectomy was associated with an increased rate of 30-day mortality and wound infections. CONCLUSION: Subtotal cholecystectomy is associated with significant morbidity. Laparoscopic and reconstituting surgery may reduce the risks of some perioperative complications and long-term sequelae after subtotal cholecystectomy.

Introduction: Cholecystectomy is the most frequently performed procedure in general surgery. The consent procedure for cholecystectomy needs to inform patients about the possibility of subtotal cholecystectomy (STC) as an alternative procedure used for "difficult gallbladders" as it is associated with increased postoperative morbidity. We sought to determine the quality of informed consent for patients who were scheduled for cholecystectomy but underwent STC, and evaluate whether patient or procedural factors influenced the information discussed in consenting. Materials and Methods: We classified 57 components of information necessary for a patient to give informed consent for cholecystectomy. We retrospectively reviewed the consent forms of patients scheduled for conventional cholecystecomy but instead undergoing STC between 2011 and 2017. Consent quality was measured as the percentage of components completed. Subgroup analyses were conducted to determine whether age, gender, American Society of Anesthesiologists grade, setting (elective/nonelective), operation mode (open/laparoscopic), or the responsible surgeon affected consent quality. Results: Across 174 patients, just 9 (5.2%) had been informed about the possibility of undergoing STC, whereas the overall quality of consent was 37.5%. Patient and setting-specific factors affected the completion of specific consent components. Patients were more likely to receive a patient information leaflet if they were female (relative risk [RR] 2.76; 95% confidence interval [CI] 1.09-7.00), <60 years (RR 3.32; 95% CI 1.39-7.90) or undergoing laparoscopic surgery (RR 8.04; 95% CI 2.50-25.88). Conclusion: The suboptimal quality of consent and multiple inconsistencies in the information disclosed to different patient cohorts emphasize the need for a more transparent and consistent consenting process.
