Hospital readmission after management of appendicitis at freestanding children's hospitals: contemporary trends and financial implications

IntroductionThe purpose of this study was to characterize epidemiologic trends and cost implications of hospital readmission after treatment of pediatric appendicitis.MethodsWe conducted a 5-year retrospective cohort analysis of 30-day readmission rates for 52,054 patients admitted with appendicitis at 38 children's hospitals participating in the Pediatric Health Information System database. Patients were categorized as “uncomplicated” (postoperative length of stay [LOS] ≤2 days) or “complicated” (LOS ≥3 days and ≥4 consecutive days of antibiotics) and analyzed for demographic data, treatment received during the index admission, readmission rates, and excess LOS and hospital-related costs attributable to readmission encounters.ResultsThe aggregate 30-day readmission rate was 8.7%, and this varied significantly by disease severity and management approach (uncomplicated appendectomy, 5.6%; complicated appendectomy, 12.8%; drainage, 22.6%; antibiotics only, 24.6%; P < .0001). The median hospital cost per case attributable to readmission was $3401 (reflecting a 44% relative increase in cumulative treatment-related cost), and this varied significantly by disease severity and management approach (uncomplicated appendectomy, $1946 [31% relative increase]; complicated appendectomy, $6524 [53% increase]; drainage, $6827 [48% increase]; antibiotics only, $5835 [58% increase]; P < .0001).ConclusionIn freestanding children's hospitals, readmission after treatment of pediatric appendicitis is a relatively common and costly occurrence. Collaborative efforts are needed to characterize patient, treatment, and hospital-related risk factors as a basis for developing preventative strategies.     

Initial experience with same day discharge after laparoscopic appendectomy for nonperforated appendicitis

Background

Although many laparoscopic procedures are performed on an outpatient basis, patients who have undergone a laparoscopic appendectomy have typically stayed at least overnight. Recently, data in both the pediatric and adult literature suggest that same day discharge (SDD) for acute nonperforated appendicitis is safe and associated with high patient and parent satisfaction. We have recently begun attempting SDD for nonperforated appendicitis, and this study is an analysis of our initial experience.

Methods

A retrospective chart review of all patients who underwent laparoscopic appendectomy for nonperforated appendicitis at our institution from January 2012 to July 2013 was performed. Demographics, length of stay, hospital course, and outcomes were measured. Data are expressed as mean ± standard deviation. Comparative analysis was performed using a t-test.

Results

A total of 588 laparoscopic appendectomies for nonperforated appendicitis were performed over an 18-mo period. Approximately 28% (n = 128) were discharged on the day of surgery. Of the remaining patients, 12.9% (n = 59) stayed overnight for medical reasons, 0.4% (n = 2) stayed for social reasons, 3.9% (n = 18) stayed because the operation ended late in the evening, and 82.8% (n = 381) stayed because of clinical care habits. Compared with patients who stayed overnight, there was no statistically significant difference in readmission rates (0.7% versus 1.9%, P = 0.6%), follow-up before scheduled appointment (5.4% versus 5.4%, P = 1.0), and complication rate (0.7% versus 2.6%, P = 0.3). Patients whose operation ended later in the day had a longer hospital stay. We observed a trend toward more SDDs, the further we got from the initiation of our protocol.

Conclusions

SDD is safe for children undergoing laparoscopic appendectomy for nonperforated appendicitis. The two main barriers to SDD were time of day for the operation and provider habit, both of which improved as more practitioners felt comfortable with the concept. SDD requires extensive education within the hospital system, and we have initiated an aggressive prospective protocol to improve the results.     

Distribution of acute appendicitis care in children: A statewide assessment of the surgeons and facilities providing surgical care

BackgroundPediatric appendicitis is managed by general and pediatric surgeons at both children’s hospitals and non-children’s hospitals. A statewide assessment of surgeons and facilities providing appendicitis care was performed to identify factors associated with location of surgical care.MethodsChildren aged <18 years undergoing appendectomy for appendicitis in Wisconsin from 2018-2020 were identified through the International Classification of Diseases, 10th revision, and Current Procedural Terminology codes using Wisconsin Hospital Association data. Patient residence and hospital locations were used to determine travel distance, rurality, and neighborhood-level socioeconomic status.ResultsAmong 3,604 children with appendicitis, 36.0% and 12.8% had an appendectomy at 2 major children’s hospitals and 4 other children’s hospitals, respectively, and 51.2% had an appendectomy at 99 non-children’s hospitals. Pediatric surgeons performed 76.1% of appendectomies at children’s hospitals and 2.9% at non-children’s hospitals. Only 32.2% of patients received care at the hospital closest to their homes. Non-children’s hospitals disproportionally cared for older, non-Hispanic White, and privately insured children, those with uncomplicated appendicitis, and those living in rural areas, in mid-socioeconomic status neighborhoods, and greater distances from children’s hospitals (all P < .001). After multivariable adjustment, receipt of care at children’s hospitals was associated with younger age, minority race, complicated appendicitis, shorter distance to children’s hospitals, and urban residence.ConclusionOver half of surgical care for pediatric appendicitis occurred at non-children’s hospitals, especially among older children and those living in rural areas far from children’s hospitals. Future work is necessary to determine which children benefit most from care at children’s hospitals and which can safely receive care at non-children’s hospitals to avoid unnecessary time and resource utilization associated with travel to children’s hospitals.     

Laparoscopic versus open appendectomy in children with uncomplicated and complicated appendicitis

Purpose

To address whether laparoscopic appendectomy could be an alternative to conventional open appendectomy in children with complicated appendicitis as well as uncomplicated appendicitis, a retrospective study comparing laparoscopic and open appendectomies was performed.

Methods

One hundred patients who were treated by immediate appendectomy, either laparoscopically or by the open method, between May 2000 and August 2003 were included in the study. There were 53 patients in the laparoscopic appendectomy group and 47 patients in the open appendectomy group.

Results

The operating time was significantly longer for laparoscopic appendectomy than for open appendectomy (P < .001). The length of hospital stay was significantly shorter in laparoscopic appendectomy in patients with uncomplicated appendicitis (P = .001). Thirteen of the 100 patients (13.0%) had 15 postoperative complications including wound infection (n = 8), intraabdominal abscess (n = 4), stitch abscess (n = 2), and small bowel obstruction (n = 1). In both uncomplicated and complicated appendicitis, there was no significant difference between laparoscopic and open appendectomies in the complication rates, and the incidences of each complication did not differ between the procedures. Among the 14 patients with generalized peritonitis, postoperative complications were seen in 5 patients (35.7%). Although the presence of generalized peritonitis was associated significantly with postoperative complications (P = .017), there was no significant association between the procedure and complications. Overall treatment costs were increased by 26.0% in laparoscopic appendectomy.

Conclusions

Laparoscopic appendectomy should remain an option in children with uncomplicated and complicated appendicitis, and when laparoscopy is selected, consideration of the advantages and disadvantages of the procedure is essential.     

Streptococcus milleri in intraabdominal abscesses in children after appendectomy: incidence and course

IntroductionIntraabdominal abscesses are a common complication after appendectomy, especially in children. In this study, we describe the incidence and course of this complication in relation to the cultured pathogens found in intraabdominal abscesses.MethodsThe charts of all patients between 1 and 18 years of age undergoing appendectomy in 3 hospitals between January 2006, and July 2009, were retrospectively reviewed. Presence of an intraabdominal abscess was confirmed with abdominal ultrasound examination. We collected all details concerning the appendectomy, pus cultures, and postoperative course in these patients.ResultsTwo hundred fifty-nine patients underwent appendectomy during the study period. Subsequently, abdominal ultrasound studies showed an intraabdominal abscess in 18 (7%) patients. Intraabdominal abscesses developed more frequently after perforated appendicitis (23%) than after simple appendicitis (2%). The incidence of postoperative abscesses did not differ significantly between open (5.6%) or laparoscopic (6.3%) appendectomy. However, the rate was high (38%) in the patients in whom the appendectomy was converted from laparoscopic to open. In 15 out of the 18 patients with a postoperative abscess drainage was performed. In pus cultures of the drained abscesses Streptococcus milleri and Escherichia coli were the most commonly isolated pathogens. Presence of S milleri was associated with prolonged hospital stay (13.9 versus 9.0 days, P = .105) and prolonged antibiotic treatment (11.3 versus 4.8 days, P = .203).ConclusionsThe incidence of intraabdominal abscesses is high after perforated appendicitis in children (23%). Our data suggest that the presence of S milleri correlates with a more complicated postoperative course after appendectomy in children.     

Population-based cohort study of the correlation between provision of care and the risk for complications after appendectomy in children

PurposeTo investigate the impact of hospital administrative level and caseload of pediatric appendectomies on the morbidity and mortality after appendectomy in a population-based cohort of Swedish children.MethodsPopulation-based cohort study including all Swedish children less than 15 years of age that underwent appendectomy for suspected appendicitis, 1987–2009. Patient characteristics and data on postoperative morbidity and mortality were collected from the Swedish National Patient Register and the Swedish Death Register. Primary endpoints were postoperative morbidity and mortality. Two explanatory variables were investigated: hospital administrative level and hospital annual caseload of pediatric appendectomies. Data were analyzed in regression models adjusting for available confounders.ResultsThe cohort comprised 55,591 children. The risk for postoperative complications was reduced in specialized pediatric surgical centers and in high caseload centers, compared to other hospitals. There were only seven postoperative deaths within 90 days of appendectomy.ConclusionsWe found clinically relevant risk reductions for reoperation and for readmission after appendectomy in specialized pediatric surgical centers. Importantly, the risk for postoperative complications was also reduced with increased hospital caseload, indicating that the merit from centralizing the management of pediatric appendectomies to specialized pediatric surgical centers may also be achieved by increasing hospital caseload of pediatric appendectomies in non-pediatric surgical units.Type of studyTreatment study.Level of evidenceLevel II.     

Utilization of a specimen retrieval bag during laparoscopic appendectomy for both uncomplicated and complicated appendicitis is not associated with a decrease in postoperative surgical site infection rates

BackgroundTo determine whether utilization of a retrieval bag during laparoscopic appendectomy for uncomplicated and complicated appendicitis (perforation/abscess) is associated with postoperative surgical site infection rates.MethodsWe studied patients presented in the database of the 2016 Appendectomy-Targeted American College of Surgeons National Surgical Quality Improvement Program who underwent laparoscopic appendectomy for pathology-confirmed appendicitis. The primary predictor variable was intraoperative utilization of a specimen retrieval bag for removal of the appendix from the peritoneal cavity. The primary outcome variable was 30-day postoperative surgical site infection. Logistic regression analysis was used to determine the association between use of a specimen retrieval bag and postoperative surgical site infection rate after adjustment for patient- and disease-related variables.ResultsA total of 10,357 patients were included for analysis. Of these procedures, 9,585 (92.6%) included the use of a specimen bag and 772 (7.5%) did not. The 30-day incidence of postoperative surgical site infection was 4.2% in the group in which no bag was used and 3.6% in the group in which a bag was used (adjusted odds ratio of surgical site infection with no bag utilization was 1.15 [95% confidence interval 0.78–1.69; P = .49]). The lack of a statistically significant association between bag utilization and postoperative surgical site infection incidence was also demonstrated for a subgroup of patients with perforated appendicitis.ConclusionUtilization of a retrieval bag during laparoscopic appendectomy is not associated with a statistically significant decrease in postoperative surgical site infection for either uncomplicated or complicated acute appendicitis.     

Stump appendicitis after laparoscopic appendectomy; laparoscopic management and literature review

IntroductionAppendectomy is one of the most common surgical procedures performed worldwide There are different etiologies for acute appendicitis such as obstruction of the appendiceal lumen by fecalith, lymphoid hyperplasia, or neoplasm.Laparoscopic appendectomy has become the treatment of choice for both complicated and uncomplicated appendicitis; common postoperative complications include wound infection, bleeding, intraabdominal abscess.Stump appendicitis is defined as the interval repeated inflammation of remaining residual appendiceal tissue after an appendectomy.Presentation of case38-Year-old female patient with a history of laparoscopic appendectomy performed in 2016 for acute uncomplicated appendicitis.She arrived to the emergency room due to abdominal pain 7 out of 10, located in the periumbilical region, later with migration to the right lower quadrant, abdominal CT scan evidenced the presence of a cecal and pericecal inflammatory process as well as the base and residual proximal portion of the cecal appendix laparoscopic stump appendectomy was performed.DiscussionStump appendicitis (SA) is defined as the inflammation of the remnant of the cecal appendix after an appendectomy, whether due to impaction of a fecalith or secondary to an ischemic process, the probability of developing SA is estimated to be about 1/50,000 cases throughout life.The most frequently used treatment is exploratory laparotomy to complete the previous appendectomy; however, there are 5 reported cases of stump appendicitis, where surgical resolution was performed through laparoscopic surgery.ConclusionsIt is important to keep this entity in mind when evaluating a patient with acute abdomen with previous history of appendectomy, since the delay in diagnosis and treatment increases morbidity and mortality; laparoscopic stump appendectomy has been shown to be a safe treatment (Agha et al., 2020 [14]).¹     

Nationwide management of perforated pediatric appendicitis: Interval versus same-admission appendectomy

PurposeAlthough conservative management followed by readmission for interval appendectomy is commonly used to manage perforated appendicitis, many studies are limited to individual or noncompeting pediatric hospitals. This study sought to compare national outcomes following interval or same-admission appendectomy in children with perforated appendicitis.MethodsThe Nationwide Readmission Database was queried (2010–2014) for patients <18 years old with perforated appendicitis who underwent appendectomy using ICD9-CM Diagnosis codes. A propensity score-matched analysis (PSMA) utilizing 33 covariates between those with (Interval Appendectomy) and without a prior admission (Same-Admission Appendectomy) was performed to examine postoperative outcomes.ResultsThere were 63,627 pediatric patients with perforated appendicitis. 1014 (1%) had a prior admission for perforated appendicitis within one calendar year undergoing interval appendectomy compared to 62,613 (99%) Same-Admission appendectomy patients. The Interval Appendectomy group was more likely to receive a laparoscopic (87% vs. 78% same-admission) than open (13% vs. 22% same-admission; p < 0.001) operation. Patients receiving interval appendectomy were more likely to have their laparoscopic procedure converted to open (5% vs. 3%) and receive more concomitant procedures. PSMA demonstrated a higher rate of small bowel obstruction in those receiving Same-Admission appendectomy while all other complications were similar. Although those receiving Interval Appendectomy had a shorter index length of stay (LOS) and lower admission costs, they incurred an additional $8044 [$5341-$13,190] from their prior admission.ConclusionPatients treated with interval appendectomy experienced more concomitant procedures and incurred higher combined hospitalization costs while still having a similar postoperative complication profile compared to those receiving same-admission appendectomy for perforated appendicitis.Level of evidenceIII.Type of studyRetrospective Comparative Study.     

Association between appendiceal stump closure method and post-operative bowel obstruction after laparoscopic appendectomy

BackgroundLaparoscopic appendectomy is one of the most common urgent pediatric surgical operations. Endoscopic surgical staplers and pre-tied endoloop ligatures are both routinely used for closure of the appendiceal stump in children. Practice patterns vary for a number of reasons, including cost, size, and ease of use. While stapling is standard for some pediatric surgeons, others believe that staples can act as a nidus for small bowel obstruction (SBO). However, studies comparing closure methods have been conflicting in their results and limited in size. Therefore, we aim to determine if there is an association between appendiceal stump closure method and SBO using a national comparative pediatric database.MethodsWe queried the Pediatric Health Information System (PHIS) for patients ages 3–18 years who underwent laparoscopic appendectomy for appendicitis between 1/1/2016 – 12/31/2020. We included hospitals that had greater than 50 patients with billing data and excluded patients with inflammatory bowel disease and simultaneous abdominal operations. We used billing data for the patient's appendectomy to determine if a stapler or a suture ligature was used during the case. Our primary outcome of interest was post-operative SBO or reoperation for lysis of adhesion or intestinal surgery within the first 30 post-operative days. Multivariable regression analyses were used to estimate the association between stump closure method and post-operative SBO or reoperation in addition to cost while adjusting for patient demographics and appendiceal perforation.ResultsIn total, 49,191 patients from 37 hospitals were included, of which, 29,733 (60.44%) were male, 21,403 (43.51%) were non-Hispanic white, and 18,291 (37.18%) had a diagnosis of complicated appendicitis. The median [IQR] age of the cohort was 11 [8–14] years. A surgical stapler was used during laparoscopic appendectomy in 35,788 (72.75%) patients, and early SBO or reoperation occurred in 653 (1.33%) patients. In adjusted analysis controlling for demographics and complicated appendicitis there was no statistically significant difference in the odds of SBO or reoperation between the two groups. (OR 1.17; 99% CI 0.86 – 1.6). Complicated appendicitis was the factor most associated with post-operative SBO or reoperation (OR 4.4; 99% CI 3.01 – 6.44). Median cumulative cost was slightly higher on unadjusted analysis in the stapler group ($10,329.3 vs $9,569.2). However, there was no significant difference on adjusted analysis.ConclusionSBO or reoperation following laparoscopic appendectomy for appendicitis is uncommon. Complicated appendicitis is the most predictive factor of this outcome. Adjusting for available patient, disease, and hospital characteristics, use of a surgical stapler does not appear to be meaningfully associated with the development of acute SBO or reoperation. Surgeon preference remains the mainstay for safe appendiceal stump closure method.Level of evidenceLevel III.Study typeRetrospective Comparative Study.     

Intra-abdominal abscess after laparoscopic appendectomy for perforated appendicitis

HYPOTHESIS: The incidence of postoperative intra-abdominal abscess is higher after laparoscopic compared with open appendectomy for perforated appendicitis. METHODS: A historical cohort study of pediatric patients operated on for suspected appendicitis by open appendectomy or laparoscopic appendectomy compares the incidence of postoperative intra-abdominal abscess for each procedure. SETTING: A tertiary care center. PATIENTS: Five hundred thirty-eight pediatric patients were operated on for suspected appendicitis at our institution between 1974 and 1999. Of these, 453 were included in the study. Of the excluded patients, 9 had incomplete medical records, 69 had normal or interval appendectomies, and 7 had appendixes removed by methods other than laparoscopy or right lower quadrant incision. INTERVENTIONS: Open appendectomy performed through a right lower quadrant incision or laparoscopic appendectomy performed through a 3-trocar approach by 1 of 3 pediatric surgeons at our institution. MAIN OUTCOME MEASURE: The incidence of postoperative intra-abdominal abscess after laparoscopic vs open appendectomy. RESULTS: In perforated appendicitis (170 patients), the incidence of postoperative abscess after laparoscopic appendectomy was 24% vs 4.2% after open appendectomy. The relative risk ratio of developing a postoperative abscess after perforated appendicitis was 5.6 (confidence interval, 2.1-16.0) after laparoscopic vs open appendectomy. The results remained significant when controlled for age, sex, intraoperative irrigation, and preoperative antibiotics. Postoperative abscess in all acute, gangrenous, and perforated appendicitis after laparoscopic appendectomy was 6.4% vs 3.0% after open appendectomy. This was not statistically significant. CONCLUSION: There is a significant increase in the incidence of postoperative intra-abdominal abscess with perforated appendicitis after laparoscopic compared with open appendectomy in pediatric patients.     

Post operative pediatric appendicitis nurse-driven discharge: Patient outcomes and nursing perspectives

BackgroundNurse-driven discharge pathways following pediatric appendectomies have proven effective in children’s hospitals; studies in general hospital settings are lacking. Additionally, despite the central role of nursing in such pathways, nursing perspectives aren’t investigated in the literature.MethodsData from all pediatric acute uncomplicated appendicitis patients who underwent laparoscopic appendectomy in the 12 months following institution of a nurse-driven discharge pathway (intervention, n = 67) were compared to those treated in the preceding year (control, n = 64). Surveys on the pathway were distributed to pediatric ward nurses.ResultsPostoperative length of stay (POLOS) decreased by 37% in the intervention group, about 6 h, (0.44 days ± 0.22 vs 0.7 days ± 0.27, p-value 0.0001), without a significant increase in related readmissions. Same day discharges increased from 10.9% to 46.3%, (P-value 0.0001). Nurse surveys revealed a high approval of the pathway (7–10/10) and yielded valuable feedback.ConclusionA nurse-driven discharge pathway decreased POLOS without increasing readmission following pediatric laparoscopic appendectomy in a general hospital setting. Valuable insight into nursing perspectives on this pathway was acquired.     

It's time to deconstruct treatment-failure: A randomized controlled trial of nonoperative management of uncomplicated pediatric appendicitis with antibiotics alone

BackgroundPublished data demonstrate that management of uncomplicated pediatric appendicitis with antibiotics-alone is safe and frequently successful. Randomized controlled trials (RCT) comparing antibiotics-alone to appendectomy are lacking, alongside insight into drivers of failure. We sought to validate the antibiotics-alone approach and identify barriers to success using an RCT design.MethodsPatients aged 6–17 years with uncomplicated appendicitis were randomized to appendectomy or intravenous piperacillin/tazobactam for 24–48 h followed by 10 days of oral ciprofloxacin/metronidazole. Enrollment required symptoms <48 h, WBC<18, appendiceal diameter <11 mm, and radiographic absence of perforation. Lack of clinical improvement or persistently elevated WBC resulted in appendectomy. Primary outcomes were 1-year success rate of antibiotics-alone and quality-of-life measures.ResultsAmong 39 children enrolled over 31 months, 20 were randomized to antibiotics-alone and 19 to surgery. At 1 year, 6 nonoperative patients underwent appendectomy (70% success). Four cases were not true antibiotic failures but instead reflected “pragmatic” challenges to executing nonoperative algorithms. Only 2 cases represented recurrent/refractory appendicitis, suggesting a 90% adjusted 1-year success rate. Parental PedsQL? scores were similar between treatment cohorts (91.3 vs 90.2, P = 0.32). Children treated with antibiotics-alone had faster return to activity (2.0 vs 12 days, P = 0.001) and fewer parental missed work days (0.0 vs 2.5, P = 0.03).ConclusionsThese data corroborate findings from non-randomized studies suggesting 70–90% of uncomplicated pediatric appendicitis can be treated with antibiotics-alone, with fewer disability days. Failures appear multifactorial, often reflecting practical hurdles and not antibiotic limitations. As surgeons consider nonoperative protocols for uncomplicated appendicitis, these data further inform the variability of treatment success.Level of evidence1; randomized controlled trial.     

The contemporary appendectomy for acute uncomplicated appendicitis in children

BackgroundNational, procedure-specific clinical registries are increasingly available in surgery, although data about children have lagged behind. Data related to the surgical management of appendicitis in children have become available recently and can be used to inform patient and family expectations and to identify clinical areas in need of ongoing improvement.MethodsCases of acute, uncomplicated appendicitis in children (<18 years of age) were extracted from the 2017 pediatric appendectomy-targeted file of the American College of Surgeons National Surgical Quality Improvement Program. Epidemiologic data were generated across 5 domains: (1) patient characteristics/severity, (2) preoperative imaging patterns, (3) characteristics of the operation, (4) pathologic outcomes, and (5) postoperative morbidity and mortality.ResultsThe final sample included 9,507 appendectomies for acute, uncomplicated appendicitis performed at 106 hospitals. The population was predominantly male (60.6%), involving children 6 to 12 years of age (55.3%). Only 2.9% of patients did not have imaging before their appendectomy. Overall, 38.2% received a computed tomography; however, patients transferred with imaging received computed tomography at 3.8 times the rate of those with only local (ie, operating hospital) imaging. Laparoscopy was used in 94.6% of cases, with 1.1% converted to open. Negative appendectomy and complication rates were 3.3% and 2.1%, respectively. Children ≤5 years of age had 2.3 greater odds of negative appendectomy than children 6 to 17 years of age.ConclusionChildren undergoing operation for acute, uncomplicated appendicitis have excellent clinical outcomes, although children ≤5 years of age have an increased risk of negative appendectomy. Despite guidelines against their use, more than one-third of children received a computed tomography before operation, driven predominantly by transferring hospitals.     

A prospective same day discharge protocol for pediatric appendicitis: Adding value to a common surgical condition

Purpose

Standardized clinical pathways for simple appendicitis decrease length of stay and result in cost savings. We performed a prospective cohort study to assess a same day discharge (SDD) protocol for children with simple appendicitis.

Defining the treatment strategy for uncomplicated appendicitis based on patient satisfaction feedback: A cross-sectional study

BackgroundTwo surgical strategies are available for appendicitis: emergency laparoscopic appendectomy and interval laparoscopic appendectomy. However, timing of surgical intervention remains debatable. This study aimed to compare the surgical outcomes of emergency laparoscopic appendectomy and interval laparoscopic appendectomy and conduct a questionnaire survey to investigate the use of emergency laparoscopic appendectomy and patient satisfaction with regard to treatment.MethodsWe included 162 patients who underwent laparoscopic appendectomy at our hospital. Outcomes were assessed by operation time, blood loss, postoperative fasting time, length of hospital stay, and complication rate. Patient satisfaction was measured by questionnaire addressing degree of satisfaction, presurgery anxiety, and length of hospital stay.ResultsOf 162 patients, 74 (46%) and 88 (54%) received emergency and interval laparoscopic appendectomy, respectively. No significant difference was observed in the operation time, blood loss, length of hospital stay, or complication rate. Among 66 patients who responded to the questionnaire (28 emergency, 38 interval), a significant difference was observed only in the degree of satisfaction regarding the timing of the surgical intervention (p = 0.04).ConclusionSurgical outcomes of emergency and interval appendectomy were equivalent; however, patient satisfaction favored emergency appendectomy, suggesting it is a preferable approach for the treatment of uncomplicated appendicitis.     

Thirty-day outcomes of laparoscopic versus open appendectomy in elderly using ACS/NSQIP database

Background

Although laparoscopic appendectomy is becoming the procedure of choice over open appendectomy in the treatment of appendicitis, its role in the elderly has not been widely studied. The objective of this study was to compare the 30-day outcomes after laparoscopic versus open for appendicitis in the elderly patients.

Methods

Using the American College of Surgeons National Surgical Quality Improvement Program (ACS/NSQIP) databases for years 2005–2009, 3,674 patients (age >65 years) who underwent an appendectomy for appendicitis were identified. Seventy-two percent of the procedures were performed laparoscopically. In addition to aggregate cohort analysis, propensity score 1:1 matching was used to minimize the treatment selection bias. The association between surgical approach and morbidity, mortality, and length of stay (LOS) were analyzed.

Results

In the aggregate cohort analysis, patients who underwent an open appendectomy had a higher rate of minor morbidity (9.3% vs. 4.5%; p < 0.001), overall morbidity (13.4% vs. 8.2%, p < 0.001), and mortality (2% vs. 0.9%, p = 0.003). However, in the matched cohort analysis, open appendectomy was only associated with a higher rate of minor morbidity (9.3% vs. 5.7%; p = 0.002) and overall morbidity (13.4% vs. 10.1%; p = 0.02) but similar mortality rates (2% vs. 1.5%; p = 0.313). In matched cohort analysis, open appendectomy also was associated with a higher rate of superficial surgical site infection (SSI) (3.8% vs. 1.4%; p < 0.001) and a lower rate of organ/space SSI (1.3% vs. 2.9%; p = 0.009). Laparoscopic appendectomy was associated with a shorter LOS in both aggregate and matched cohorts compared with open appendectomy (p < 0.001).

Conclusions

Within ACS NSQIP hospitals, elderly patients benefited from a laparoscopic approach to appendicitis with regards to a shorter LOS and a lower minor and overall morbidity. Laparoscopic appendectomy was associated with lower superficial SSI and higher organ/space SSI rates.     

Same-day discharge for pediatric laparoscopic gastrostomy

BackgroundLaparoscopic gastrostomy is a common procedure in children. We developed a same-day discharge (SDD) protocol for laparoscopic button gastrostomy.MethodsWe performed a prospective observational study of children undergoing laparoscopic button gastrostomy and were eligible for SDD from August 2017–September 2019. Patients were eligible if: 1) the family was comfortable with eliminating overnight admission and were suitable candidates for outpatient surgery (absence of major co-morbidities), 2) they were not undergoing additional procedures requiring admission, and 3) they received pre-operative education.ResultsSixty-two patients who underwent laparoscopic button gastrostomy were eligible for SDD. The median age was 2.1 years [IQR 0.9–4.1], and the median weight was 10.5 kg [IQR 7.6–15.5]. Forty-one (66%) were previously nasogastric fed. The median operative time was 22 min [IQR 16–29]. The median time to initiation of feeds was 4.4 h [IQR 3.4–5.5]. Fifty-one (82%) were discharged the same day with a median length of stay of 9 h [IQR 7–10]. Eleven were admitted, most commonly for further teaching. Eleven SDD patients were seen in the emergency room < 30 days at a median 5 days [IQR 3–12] post-operatively, primarily for mechanical complications.ConclusionSame-day discharge following laparoscopic gastrostomy is safe and feasible for select pediatric patients who undergo pre-operative education. The SDD pathway results in a low admission rate and relatively low ER visits.Type of studyProspective Observational Study.Level of EvidenceLevel II.     

An evidence-based warfarin management protocol reduces surgical delay in hip fracture patients

Background

Up to 4 % of patients presenting with a hip fracture may be on warfarin at admission. There is little consensus on the timing, dosage or route of vitamin K administration. We aimed to evaluate the impact of a locally developed, evidence-based protocol for perioperative warfarin management on the admission-to-operation time (AOT) in hip fracture patients.

Materials and methods

Clinical and demographic data were collected prospectively for hip fracture patients who were on warfarin at the time of admission (post-protocol group) and compared to a historical control group of patients who were on warfarin before implementation of the protocol (pre-protocol group). Univariate analysis was undertaken to identify any significant differences between the two groups.

Results

Twenty-seven patients in the pre-protocol group (27/616, 4.4 %) and 40 patients in the post-protocol group (4.7 %, 40/855) were on warfarin at admission. There was a significant reduction in the median AOT from 73 h (IQR 46–105) to 37.7 h (IQR 28–45) after implementation of the warfarin protocol (p < 0.001). The proportion of patients operated on within 48 h of admission increased from 30 % (8/27) in the pre-protocol group to 80 % (32/40) in the post-protocol group (p < 0.001). No significant differences in hospital length of stay (p = 0.77) or the postoperative warfarin recommencement time (p = 0.90) were noted between the two groups.

Conclusion

Implementation of a perioperative warfarin management protocol can expedite surgery in hip fracture patients, but did not reduce hospital stay in our cohort, possibly because of a delay in recommencing warfarin in these patients postoperatively.

Safety and feasibility of same-day discharge for uncomplicated appendicitis: A prospective cohort study

Background

Appendicitis is the most common gastrointestinal pediatric surgical emergency. With the introduction of laparoscopic techniques in the 1990s, recovery, pain, and hospital stay after laparoscopic procedures have been significantly reduced. While many laparoscopic procedures are performed as outpatient surgeries, pediatric appendectomy patients continue to be hospitalized for postoperative observation. Our goal was to evaluate the safety and feasibility of same day discharge after laparoscopic appendectomy for uncomplicated appendicitis.
