The effects of intensive care environment on postoperative nightmare

Purpose

We retrospectively investigated the incidence of postoperative nightmares and evaluated the impact of postoperative intensive care on the incidence of during subsequent hospital stay. To reduce the effect of selection bias, we compared the incidence of nightmares in propensity-matched pairs with postoperative management in ICUs or in surgical wards.

Methods

This is a retrospective review of an institutional registry containing 21,606 anesthesia cases and was conducted with ethics board approval. Outcomes of surgical patients treated in ICUs and in postsurgical wards (ICU admission vs non ICU admission) were compared first for nightmares using the initial 12,508 patients. To avoid channeling bias, propensity score analysis was used to generate a set of matched cases (ICU admission) and controls (non ICU admission), yielding 642 matched patient pairs. The incidence rate of nightmares was compared as the primary outcome.

Results

Before adjusting patients’ characteristics, ICU environment exposure increased the incidence of nightmares compared with non-ICU environment during subsequent hospital stay [ICU vs non-ICU: 101/718 (12.3 %) vs 1147/10,542 (9.81 %)]. The odds ratio (95 % CIs) for ICU was 1.29 (1.03–1.61) for nightmares (p = 0.022). After propensity score matching, however, an equal rate of nightmares occurred in the ICU environment exposure compared to the non-ICU environment [ICU vs non-ICU: 81/561 (12.6 %) vs 73/569 (11.4 %)]. The odds ratio and 95 % CIs for ICU were 1.13 (0.80–1.58) for nightmares (p = 0.54).

Conclusions

The incidence of nightmares did not become more evident during subsequent hospital stay after ICU environment exposure.

     

The impact of frailty syndrome and risk scores on emergency cholecystectomy patients

Purpose

Cholecystectomy, which is one of the most common surgical procedures, is also performed in the emergency setting. A number of risk scores have been introduced in recent studies; moreover, over the last few years literature has focused on surgical patients with frailty syndrome. The aim of the present study is to evaluate whether frailty syndrome and the risk scores are correlated with morbidity, post-operative hospital stay and the ICU admission rate following emergency cholecystectomy.

Methods

Eighty-five consecutive patients of >65 years of age who underwent cholecystectomy were selected from 2306 emergency procedures for inclusion in the present study. The patients were assessed for frailty syndrome and their scores were calculated on the basis of chart review. Univariate analyses were performed to compare severe frailty patients to intermediate frailty and robust patients. ROC and logistic regression analyses were performed with the end-points of morbidity, hospital stay and ICU admission.

Results

In addition to having worse ASA, inflammatory and risk values than robust patients, frailty syndrome patients also had higher rates of morbidity and ICU admission and longer hospitalization periods. A logistic regression analysis showed that the P-Possum was independently correlated with morbidity. Frailty and open surgery were independently correlated with longer hospitalization, whereas ICU admission was correlated with worse ASA and P-Possum values.

Conclusions

Frailty syndrome significantly impacts the length of hospitalization in patients undergoing emergency cholecystectomy. Although the ORs were limited, the P-Possum value was independently associated with the outcome.

     

Is a stepdown unit safe for patients with mild traumatic intracranial hemorrhages?

Purpose

Traumatic brain injuries (TBIs) are a major source of disability in the United States. The ideal unit in the hospital for patients with mild traumatic intracranial hemorrhages (ICHs) has not been elucidated. We sought to investigate whether patients treated in the surgical stepdown area had worse outcomes than those treated in the surgical ICU.

Methods

We compared patients with ICHs and a Glasgow Coma Scale (GCS) upon admission of 14 or 15 who went to the ICU to those who went to the stepdown area from April 2014 to November 2016. We compared age, gender, Injury Severity Score (ISS), admission GCS (14 or 15), operative intervention, discharge destination, hospital length of stay (HLOS), mortality, and cost between these two groups.

Results

Patients admitted to the ICU had a significantly longer HLOS. Admission costs for patients admitted to ICU were also significantly higher than their stepdown area counterparts. This was true for both total charges (p?=?0.0001) and for net revenue (p?=?0.002) (Table 2). There was no statistically significant difference in mortality, operative intervention, or discharge destination.

Conclusion

A surgical stepdown unit can be a safe disposition for patients with mild traumatic ICHs and represents an effective use of hospital resources.

     

Associations of Hospital Length of Stay with Surgical Site Infections

Background

Surgical site infections (SSI) are a major cause of morbidity and mortality in surgical patients. Postoperative and total hospital length of stay (LOS) are known to be prolonged by the occurrence of SSI. Preoperative LOS may increase the risk of SSI. This study aims at identifying the associations of pre- and postoperative LOS in hospital and intensive care with the occurrence of SSI.

Methods

This observational cohort study includes general, orthopedic trauma and vascular surgery patients at two tertiary referral centers in Switzerland between February 2013 and August 2015. The outcome of interest was the 30-day SSI rate.

Results

We included 4596 patients, 234 of whom (5.1%) experienced SSI. Being admitted at least 1 day before surgery compared to same-day surgery was associated with a significant increase in the odds of SSI in univariate analysis (OR 1.65, 95% CI 1.25–2.21, p?<?0.001). More than 1 day compared to 1 day of preoperative hospital stay did not further increase the odds of SSI (OR 1.08, 95% CI 0.77–1.50, p?=?0.658). Preoperative admission to an intensive care unit (ICU) increased the odds of SSI as compared to hospital admission outside of an ICU (OR 2.19, 95% CI 0.89–4.59, p?=?0.057). Adjusting for potential confounders in multivariable analysis weakened the effects of both preoperative admission to hospital (OR 1.38, 95% CI 0.99–1.93, p?=?0.061) and to the ICU (OR 1.89, 95% CI 0.73–4.24, p?=?0.149).

Conclusion

There was no significant independent association between preoperative length of stay and risk of SSI while SSI and postoperative LOS were significantly associated.

     

Critical Care in a Tertiary Hospital in Malawi

Background

The provision of critical care services is essential to healthcare systems and increasingly a global health focus, but many hospitals in sub-Saharan Africa are unable to meet this need. Intensive care unit (ICU) mortality in this region is high, but studies describing the provision of critical care services are scarce.

Methods

This was a retrospective cohort study of all patients admitted to the ICU at Queen Elizabeth Central Hospital (QECH) in Blantyre, Malawi, between September 1, 2013, and October 17, 2014. We summarized demographics, clinical characteristics, and outcomes, and analyzed factors associated with mortality.

Results

Of 390 patients admitted to ICU during the study, 44.9 % of patients were male, and the median age was 22 years (IQR 6–35) years. Although most patients (73.1 %) were admitted with surgical diagnoses, the highest mortality was among patients admitted with sepsis (59.3 %), or obstetric (44.7 %) or medical (40.0 %) diagnoses. Overall ICU mortality was high (23.6 %).

Conclusions

There is a shortage of data describing critical care in low-resource settings, particularly in sub-Saharan Africa. Surgical disease comprises the majority of ICU utilization in this study site, but medical and obstetric illness carried higher ICU mortality. These data may guide strategies for improving critical care in the region.

     

Managing the open abdomen: negative pressure closure versus mesh-mediated fascial traction closure: a randomized trial

Purpose

To compare the effectiveness of abdominal wall closure using the vacuum-assisted closure (NPC) as described by Barker et al. with an institutional protocol using a double polyvinyl bag in the first surgery, which is changed in subsequent surgeries to a polyvinyl bag placed over the bowel loops and a prolene mesh attached to the abdominal fascia (MMFC).

Methods

Randomized controlled trial. Patients with open abdomen (OA) due to a traumatic or a medical cause were included in the study. Variables studied included demographics, indication for surgery, number of interventions, hospital length of stay (HLOS), ICU length of stay, abdominal wound care costs, complication rates, and method and time to definitive fascial closure.

Results

From June 2011 to April 2013, 75 patients were enrolled in the study. Patients who died within 48 h were excluded; therefore, 53 patients in total were assessed. NPC achieved fascial closure in 75 % of patients, and MMFC achieved closure in 71.9 % of patients. The closure rates in patients with OA secondary to medical causes (80 % by NPC vs. 71.4 % by MMFC) or traumatic causes (70 % by NPC vs. 73.7 % by MMFC) were similar in both treatment groups. There were no differences between the groups with respect to cause of OA, complications, length of hospital stay, or the length of stay in the intensive care unit.

Conclusion

MMFC is a method comparable to NPC for the temporary management of OA that results in similar closure and complication rates.

     

Cholecystectomy During the Weekend Increases Patients’ Length of Hospital Stay

Background

A higher risk of complications and mortality has previously been proven in selected settings. The purpose of this study was to investigate whether length of stay differentiates throughout the week and register if intra- and postoperative complications vary on weekends compared to weekdays.

Methods

The population originated from the Danish Cholecystectomy Database. It consists of adult patients, who had a cholecystectomy performed by standard four-port laparoscopic or open surgery. Adjusted analyses were used to study if day of the week had an influence on conversion, readmission within 30 days, post-operative supplemental procedures within 30 days, and variance in postoperative length of stay across the week.

Results

A total of 28,759 patients were included in the study. We found no difference in conversion rate, readmission within 30 days, or post-operative procedures within 30 days between week time and weekend time. A longer postoperative length of stay was observed for patients operated on Fridays and Saturdays even though surgical complication rates were alike between weekdays. Patients with acute cholecystitis had a longer length of stay on Saturdays.

Conclusion

We found no evidence of a higher risk of conversions, post-operative procedures, or readmission during weekends compared with weekdays. Despite this, a prolonged length of stay was observed in patients operated with cholecystectomy on Fridays and Saturdays. The observed difference could be due to ward rounds on weekends mainly focus on the sickest patients leaving less time for discharge.

     

Thoracic trauma severity contributes to differences in intensive care therapy and mortality of severely injured patients: analysis based on the TraumaRegister DGU®

Background

Thoracic trauma is a relevant source of comorbidity throughout multiply-injured patient care. We aim to determine a measurable influence of chest trauma’s severity on early resuscitation, intensive care therapy, and mortality in severely injured patients.

Methods

Patients documented between 2002 and 2012 in the TraumaRegister DGU®, aged ≥?16 years, injury severity score (ISS) ≥ 16 are analyzed. Isolated brain injury and severe head injury led to exclusion. Subgroups are formed using the Abbreviated Injury Scale_Thorax.

Results

Twenty-two thousand five hundred sixty-five patients were predominantly male (74%) with mean age of 45.7 years (SD 19.3), blunt trauma (95%), mean ISS 25.6 (SD 9.6). Overall mean intubation period was 5.6 days (SD 10.7). Surviving patients were discharged from the ICU after a mean of about 5 days following extubation. Thoracic trauma severity (AIS_Thorax ≥ 4) and fractures to the thoracic cage significantly prolonged the ventilation period. Additionally, fractures extended the ICU stay significantly. Suffering from more than one thoracic injury was associated with a mean of 1–2 days longer intubation period and longer ICU stay. Highest rates of sepsis, respiratory, and multiple organ failure occurred in patients with critical compared to lesser thoracic trauma severity.

Conclusion

Thoracic trauma severity in multiply-injured patients has a measurable impact on rates of respiratory and multiple organ failure, sepsis, mortality, time of mechanical ventilation, and ICU stay.

     

The impact of osteoporotic fractures compared with other health conditions in older adults living in Virginia,United States

Summary

This study compared length of stay, hospital costs, 30-day readmission, and mortality for patients admitted primarily for osteoporotic fractures to those admitted for five other common health conditions. The results indicated that osteoporotic fractures were associated with highest hospital charges and the second highest hospital stay after adjusting for confounders.

Introduction

This study aimed to compare the effect of osteoporotic fractures and other common hospitalized conditions in both men and women age 55 years and older on a large in-patient sample.

Methods

De-identified patient level and readmission and transfer data from the Virginia Health Information (VHI) system for 2008 through 2014 were merged. Logistic regression models were used to assess mortality and 30-day readmission, while generalized linear models were fitted to assess LOS and hospital charges.

Results

After adjustment for confounders, osteoporotic fractures had the second longest LOS (6.0 days, 95 % CI?=?5.9–6.0) and the highest average total hospital charges ($47,386.0, 95 % CI?=?$46,707.0–$48,074.0) compared to the other five common health problems.

Conclusion

Recognizing risk and susceptibility to osteoporotic fractures is an important motivator for individual behaviors that mitigate this disease. Furthermore, acknowledging the economic impact and disabling burden of osteoporotic fractures on society are compelling reasons to promote bone health as well as to prevent, diagnose, and manage osteoporosis.

     

Difficult airway management resources and capnography use in Japanese intensive care units: a nationwide cross-sectional study

Purpose

The availability of difficult airway management (DAM) resources and the extent of capnometry use in Japanese intensive care units (ICUs) remained unclear. The purpose of this study was to clarify whether: (1) DAM resources were adequate, and (2) capnometry was routinely applied in Japanese ICUs.

Methods

This nationwide cross-sectional study was conducted from September 2015 to February 2016. All ICUs received a mailed questionnaire about their DAM resources and use of capnometry. Outcome measures were availability of: (1) 24-h in-house backup coverage; (2) a supraglottic airway device (SGA); (3) a dedicated DAM cart; and (4) surgical airway devices, and (5) routine use of capnometry to verify tube placement and for continuous monitoring of ventilator-dependent patients. The association between these outcomes and ICU type (academic, high-volume, closed, surgical) was also analyzed.

Results

Of the 289 ICUs, 196 (67.8 %) returned completed questionnaires. In-house backup coverage and surgical airway devices were highly available (89.3 and 95.9 %), but SGAs and dedicated DAM carts were not (60.2 and 60.7 %). The routine use of capnometry to confirm tube placement was reported by 55.6 % of the ICUs and was highest in closed ICUs (67.2 %, p = 0.03). The rate of continuous capnography monitoring was also 55.6 % and was highest in academic ICUs (64.5 %, p = 0.04).

Conclusion

In Japanese ICUs, SGAs and dedicated DAM carts were less available, and capnometry was not universally applied either to confirm tube placement, or for continuous monitoring of ventilated patients. Our study revealed areas in need of improvement.

     

The Effect of Human-Immunodeficiency Virus Status on Outcomes in Penetrating Abdominal Trauma: An Interim Analysis

Background

The purpose of this study was to determine whether the outcomes of hemodynamically stable patients undergoing exploratory laparotomy for penetrating abdominal trauma differed as a result of their HIV status.

Methods

This was an observational, prospective study from February 2016 to May 2017. All hemodynamically stable patients with penetrating abdominal trauma requiring a laparotomy were included. The mechanism of injury, the HIV status, age, the penetrating abdominal trauma index (PATI), and the revised trauma score (RTS) were entered into a binary logistic regression model. Outcome parameters were in-hospital death, morbidity, admission to intensive care unit (ICU), relaparotomy within 30 days, and length of stay longer than 30 days.

Results

A total of 209 patients, 94% male, with a mean age of 29 ± 10 years were analysed. Twenty-eight patients (13%) were HIV positive. The two groups were comparable. Ten (4.8%) laparotomies were negative. There were two (0.96%) deaths, both in the HIV negative group. The complication rate was 34% (n = 72). Twenty-nine patients (14%) were admitted to the ICU. A higher PATI, older age, and a lower RTS were significant risk factors for ICU admission. After 30 days, 12 patients (5.7%) were still in hospital. Twenty-four patients (11%) underwent a second laparotomy. The PATI score was the single independent predictor for complications, relaparotomy, and hospital stay longer than 30 days.

Conclusions

Preliminary results reveal that HIV status does not influence outcomes in patients with penetrating abdominal trauma.

     

Atemwegssicherung auf Intensivstationen in Rheinland-Pfalz

Background

Securing the airway in severely ill patients is associated with a high rate of complications. So far, no information exists about the equipment readily available for airway management in German intensive care units (ICUs). It is also unknown if the range of material has improved over time.

Objectives

In the present trial the availability of equipment for airway management in ICUs in Rhineland-Palatinate was evaluated at two different times.

Materials and Methods

Using a structured questionnaire, all ICUs in the state were contacted in the years 2010 and 2015. The availability of different types of equipment for airway management, as well as the presence of a training program for airway management, was evaluated.

Results

For 2010 data from 64 ICUs were evaluated and for 2015 data sets from 63 ICUs were collected. In 2010 indirect laryngoscopes were available in eight ICUs; in 2015 these devices were directly accessible in 43 units (p < 0.0001). Extraglottic devices were available in all but one ICU in 2010 and all ICUs in 2015. Equipment for emergency surgical airway procedures was available in nearly every ICU (n = 60). The availability of capnography increased significantly from 2010 (n = 12) to 2015 (n = 56; p < 0.0001). In 2010 and 2015, frequent training with a focus on airway management was performed in 23 and 32 units, respectively (p > 0.05).

Conclusion

Most ICUs in Rhineland-Palatinate have a broad range of equipment for airway management available, and the range has significantly improved over the time period evaluated. The availability of indirect laryngoscopes and capnometers improved significantly. However, it is remarkable that in some ICU’s there is still a lack of equipment for advanced airway management.

     

Surgeon Volume Correlates with Reduced Mortality and Improved Quality in the Surgical Management of Diverticulitis

Background

Volume has been shown to be an important determinant of quality and cost outcomes.

Methods

We performed a retrospective study of patients who underwent surgery for diverticulitis using the University HealthSystem Consortium database from 2008–2012. Outcomes evaluated included minimally invasive approach, stoma creation, intensive-care admission, post-operative complications, length of stay, and total direct hospital costs by surgeon volume. Surgeon volume was categorized into four categories by mean annual volumes: very-high (VHVS) (>31), high (HVS) (13–31), medium (MVS) (6–12), and low (LVS) (≤5).

Results

A total of 19,212 patients with a mean age of 59 years, 54 % female makeup, and 55 % rate of private insurance were included. Similar to the unadjusted analysis, multivariable analysis revealed decreasing odds of stoma creation, complications, ICU admission, reoperation, readmission, and inpatient mortality with increasing surgeon volume. Additionally, compared with LVS, a higher surgeon volume was associated with higher rates of the minimally invasive approach. Median length of stay and costs were also notably lower with increasing surgeon volume.

Conclusion

Quality and the use of minimally invasive technique are tightly associated with surgeon volume. Further studies are necessary to validate the direct association of volume with outcomes in surgery for diverticulitis.

     

Early Management of Retained Hemothorax in Blunt Head and Chest Trauma

Background

Major blunt chest injury usually leads to the development of retained hemothorax and pneumothorax, and needs further intervention. However, since blunt chest injury may be combined with blunt head injury that typically requires patient observation for 3–4 days, other critical surgical interventions may be delayed. The purpose of this study is to analyze the outcomes of head injury patients who received early, versus delayed thoracic surgeries.

Materials and methods

From May 2005 to February 2012, 61 patients with major blunt injuries to the chest and head were prospectively enrolled. These patients had an intracranial hemorrhage without indications of craniotomy. All the patients received video-assisted thoracoscopic surgery (VATS) due to retained hemothorax or pneumothorax. Patients were divided into two groups according to the time from trauma to operation, this being within 4 days for Group 1 and more than 4 days for Group 2. The clinical outcomes included hospital length of stay (LOS), intensive care unit (ICU) LOS, infection rates, and the time period of ventilator use and chest tube intubation.

Result

All demographics, including age, gender, and trauma severity between the two groups showed no statistical differences. The average time from trauma to operation was 5.8 days. The ventilator usage period, the hospital and ICU length of stay were longer in Group 2 (6.77 vs. 18.55, p = 0.016; 20.63 vs. 35.13, p = 0.003; 8.97 vs. 17.65, p = 0.035). The rates of positive microbial cultures in pleural effusion collected during VATS were higher in Group 2 (6.7 vs. 29.0%, p = 0.043). The Glasgow Coma Scale score for all patients improved when patients were discharged (11.74 vs. 14.10, p < 0.05).

Discussion

In this study, early VATS could be performed safely in brain hemorrhage patients without indication of surgical decompression. The clinical outcomes were much better in patients receiving early intervention within 4 days after trauma.

     

The consistency of care for older patients with a hip fracture: are the results of the integrated orthogeriatric treatment model of the Centre of Geriatric Traumatology consistent 10 years after implementation?

Summary

In the past 10 years after implementation, the orthogeriatric treatment model led in general to consistent outcomes for 1555 older adults in terms of most of the complications and mortality. Surgery was more often delayed to 24–48 h after arrival at the hospital, while the length of hospital stay shortened.

Introduction

Since 1 April 2008, patients aged ≥?70 years presenting themselves with a hip fracture at Ziekenhuisgroep Twente (ZGT) have been treated according to the orthogeriatric treatment model. The aim of this study was to investigate if outcomes of the orthogeriatric treatment model are consistent over the first 10 years after implementation.

Methods

Between 1 April 2008 and 31 December 2016, patients aged ≥?70 years who were surgically treated at ZGT for a hip fracture were included and divided into three periods equally distributed in time. Patient characteristics, in-hospital logistics, complications, and mortality data were compared between the three periods.

Results

A total of 1555 patients were included. There was a shift in the surgical treatment for the fractured neck of femur from dynamic hip screw/cannulated screws to hemiarthroplasty (p <?0.001). Surgery within 24 h after arrival to the hospital decreased (p <?0.001), while surgery within 48 h stayed the same (p =?0.085). Length of hospital stay significantly decreased over time (p <?0.001). Complication rates were consistent except for the number of postoperative anemia, delirium, and urinary tract infections. Mortality rates did not change over the years.

Conclusions

The orthogeriatric treatment model leads in general to consistent outcomes concerning mortality and most of the complications, except for postoperative anemia, delirium, and urinary tract infections. Inconsistent complication rates were influenced by altered diagnosis and treatment protocols. Length of hospital stay reduced, while time to surgery was more often delayed to 24–48 h. Monitoring clinical outcomes of the orthogeriatric treatment model over time is recommended in order to optimize and maintain the quality of care for this frail patient population.

     

A detailed evaluation of the new acute kidney injury criteria by KDIGO in critically ill patients

Purpose

Two previous classifications of acute kidney injury (AKI) have shown that AKI is associated with increased mortality. In 2012, Kidney Disease Improving Global Outcomes (KDIGO) created new AKI criteria by combining the two previous classifications. However, such combination might cause inconsistency among each definition in the criteria. We have investigated all the definitions in the new KDIGO criteria.

Methods

We retrospectively studied 767 adult patients whose stay in the ICU exceeded 24 h. The KDIGO criteria were applied to all patients to diagnose AKI. Hospital mortality of patients with AKI diagnosed by the ten definitions in the criteria was compared.

Results

AKI occurred in 51.9 % with the standard definition of KDIGO. By multivariable analysis, odds ratios were increased with AKI stage progression and AKI stage 3 was significantly associated with hospital mortality. Crude hospital mortality stratified by the ten definitions showed increasing trends with stage progression. Mortality of the three definitions in stage 1 was from 4.0 to 10.8 %. Stage 2 had two definitions and their mortality was 13.6 and 17.6 %. Stage 3 had five definitions and their mortality ranged from 27.6 to 55.6 %.

Conclusion

AKI defined by the new KDIGO criteria was associated with increased hospital mortality. Although definitions in the KDIGO criteria seem to be appropriate because of the clear relationship between mortality and stage progression on the whole, several limitations may exist, especially in stage 3. Further research should be needed to clarify the validity of the KDIGO criteria and the detailed categories.

     

Severe Sepsis in Elderly Patients Undergoing Gastrointestinal Surgery—a Prospective Multicenter Follow-up Study of Finnish Intensive Care Units

Background

We aimed to evaluate the outcome of elderly patients with severe sepsis after alimentary tract surgery.

Methods

A prospective study was conducted in 24 intensive care units (ICU) in Finland. Four thousand five hundred consecutive patients were admitted to ICUs and 470 patients fulfilled the criteria for severe sepsis. All patients who had undergone gastrointestinal surgery were included. The outcomes of elderly (≥65 years) and younger patients were compared. The key factor under analysis was death from any cause during the hospitalization or within 1 year after the surgery.

Results

A total of 73 elderly patients (and 81 younger patients) were found to have severe alimentary tract surgery-related sepsis. The mean age of the elderly patients was 76.4 years, and 56.2 % were female. The most common indication for surgery was acute cholecystitis (21.9 %), followed by acute diverticulitis (13.7 %), and gastroduodenal ulcer (13.7 %). The anatomic site of the infection was intra-abdominal in 86.3 % of cases, the second most common being pulmonary (13.7 %). In-hospital mortality was 47.9 % and 1-year mortality 64.4 %. Of the discharged patients, 31.6 % died within 1 year. Patients who died were older and more frequently had concomitant conditions. The ICU scoring systems (APACHE, SAPS, and SOFA) and elevated lactate levels were predictive of increased mortality.

Conclusion

Severe sepsis among the elderly is a rare but often-fatal infectious event. In addition to high in-hospital mortality, it is also associated with significant 1-year mortality.

     

Robotic Liver Resection: A Case-Matched Comparison

Background

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic hepatectomy, however, is still in its infancy. Our goals were to examine the adoption of robotic hepatectomy and to compare outcomes between open and robotic liver resections.

Methods

The robotic hepatectomy experience of 64 patients was compared to a modern case-matched series of 64 open hepatectomy patients at the same center. Matching was according to benign/malignant diagnosis and number of segments resected. Patient data were obtained retrospectively. The main outcomes and measures were operative time, estimated blood loss, conversion rate (robotic to open), Pringle maneuver use, single non-anatomic wedge resection rate, resection margin size, complication rates (infectious, hepatic, pulmonary, cardiac), hospital stay length, ICU stay length, readmission rate, and 90-day mortality rate.

Results

Sixty-four robotic hepatectomies were performed in 2010–2014. Forty-one percent were segmental and 34 % were wedge resections. There was a 6 % conversion rate, a 3 % 90-day mortality rate, and an 11 % morbidity rate. Compared to 64 matched patients who underwent open hepatectomy (2004–2012), there was a shorter median OR time (p = 0.02), lower median estimated blood loss (p < 0.001), and shorter median hospital stay (p < 0.001). Eleven of the robotic cases were isolated resections of tumors in segments 2, 7, and 8.

Conclusions

Robotic hepatectomy is safe and effective. Increasing experience in more centers will allow definition of which hepatectomies can be performed robotically, and will enable optimization of outcomes and prospective examination of the economic cost of each approach.

     

Comparison of outcomes of operative versus non-operative treatment of acetabular fractures in the elderly and severely comorbid patient

Background

Acetabular fractures in the elderly and severely comorbid patient can be associated with high morbidity and mortality; however, differences in outcomes of acute ORIF versus non-operative care of acetabular fractures in a subgroup of elderly (>75 years) and/or severely comorbid younger patients (>65) remain unclear.

Patients and methods

A retrospective review of 243 patients who sustained an acetabular fracture between April 2005 and November 2014 was performed. Eighty-seven patients met inclusion criteria: age > 75 with or without comorbidities or age > 65 if complicated by two or more medical comorbidities. Outcomes measures evaluated were 1-year mortality, duration of hospital stay, return to pre-injury ambulation status and treatment failure marked by conversion to a total hip arthroplasty (THA) within 1 year of treatment.

Results

Thirty-seven patients with acetabular fractures were treated with surgical fixation, and 49 were treated non-operatively. Operative patients did not demonstrate a statistically significant difference in mortality within 1 year of treatment compared to non-operatively treated patients. Operative patients demonstrated a statistically significant increase in treatment failure marked by a conversion to a THA within 1 year when compared to conservatively treated patients. No differences in age, duration of follow-up, or ability to return to baseline at latest clinical follow-up were found between groups. However, non-operatively treated patients had a higher incidence of Alzheimer’s disease/Dementia and Parkinson’s compared to operatively treated patients.

Conclusion

Analysis of our small cohort suggests that there may be a role for the non-operative treatment of acetabular fractures in this debilitated patient population despite a somewhat longer length of hospital stay at the time of injury. Conversion to THA was significantly higher at 1 year in our operated patients. No differences in mortality at 1 year were noted between patient groups. Return to baseline ambulation status was slightly higher in the non-operated group but not significantly so. However, a potential bias to more likely treat complex fractures operatively cannot be ruled out, as non-operative fractures were most often anterior column variants, usually more amenable to non-operative care.

Results of a nationwide questionnaire-based survey on nutrition management following gastric cancer resection in Japan

Purpose

A study was conducted to clarify the actual status of nutrition management after gastric cancer surgery in Japan and obtain basic data for optimizing perioperative nutrition management.

Methods

A questionnaire was sent to 354 hospitals with at least 50 cases of gastric cancer surgery per year. Questions included the perioperative nutrition management and length of hospital stay for patients who underwent gastric cancer surgery within three months of the survey.

Results

Responses were obtained from 242 hospitals (68%; 20,858 patients). Nutrition management was consistent between laparotomy and laparoscopic surgery for 84% of respondents. The number of postoperative days was the most commonly chosen index for starting oral feeding. The most commonly chosen index for hospital dischargeability was diet composition/amount consumed in 182 hospitals (44%), followed by laboratory data stabilization in 106 hospitals (26%), and the number of postoperative days in 87 hospitals (21%). A positive correlation was found between the mean length of postoperative hospital stay and starting oral feeding (r = 0.23 for distal gastrectomy; r = 0.34 for total gastrectomy). The length of hospital stay tended to be shorter with an earlier start of oral feeding (p < 0.01).

Conclusion

Early postoperative oral feeding may be a factor in reducing the length of hospital stay after gastric cancer surgery.
