Use of a 5-Item Modified Frailty Index for Assessing Outcomes After Hartmann's Reversal: An ACS-NSQIP Study.

BACKGROUND: Half of all patients with an end colostomy after sigmoid colectomy (Hartmann's procedure) never undergo Hartmann's reversal, frequently secondary to frailty. This retrospective cohort study evaluates the utility of a five-item modified frailty index (mFI-5) in predicting post-operative outcomes after Hartmann's reversal. METHODS: The National Surgery Quality Improvement Program (NSQIP) database captured patients with elective Hartmann's reversals from 2011 to 2020. Clinical covariates were evaluated with univariate analysis and modified Poisson regression to determine association with overall morbidity, overall mortality, and extended length of stay (eLOS) when categorized by mFI-5 score. RESULTS: 15,172 patients underwent elective Hartmann's reversal (91.6% open and 8.4% laparoscopic). Patients were grouped by mFI-5 score (0: 48.7%, 1: 38.2%, ≥ 2: 13.1%). Adjusted multivariable analysis showed frail patients (mFI-5≥2) had increased overall mortality (OR 2.23, 95% CI 1.21-4.11), morbidity (OR 1.23, 95% CI 1.12-1.35), and eLOS (OR 1.12, 95% 1.02-1.23). Among frail patients, a laparoscopic approach was associated with decreased overall morbidity (OR .64, 95% CI 0.56-.73) and decreased eLOS (OR .46, 95% CI 0.39-.54) when compared to open approach. DISCUSSION: An mFI-5 of ≥2 was associated with greater morbidity, mortality, and eLOS following Hartmann's reversal. However, there were no mortality or eLOS differences in patients with an mFI-5 of 1 and only a 14% increase in any morbidity, making these patients potentially good candidates for Hartmann's reversal. Furthermore, laparoscopic surgery was associated with a protective effect for overall morbidity and eLOS, potentially mitigating some of the risk associated with higher frailty scores.

Impact of Preoperative Factors in Patients With IBD on Postoperative Length of Stay: A National Surgical Quality Improvement Program-Inflammatory Bowel Disease Collaborative Analysis.

BACKGROUND: Patients with IBD are challenging to manage perioperatively because of disease complexity and multiple comorbidities. OBJECTIVE: To identify whether preoperative factors and operation type were associated with extended postoperative length of stay after IBD-related surgery, defined by 75th percentile or greater (n = 926; 30.8%). DESIGN: This was a cross-sectional study based on a retrospective multicenter database. SETTING: The National Surgery Quality Improvement Program-Inflammatory Bowel Disease Collaborative captured data from 15 high-volume sites. PATIENTS: A total of 3008 patients with IBD (1710 with Crohn's disease and 1291 with ulcerative colitis) with a median postoperative length of stay of 4 days (interquartile range, 3-7) from March 2017 to February 2020. MAIN OUTCOME MEASURES: The primary outcome was extended postoperative length of stay. RESULTS: On multivariable logistic regression, increased odds of extended postoperative length of stay were associated with multiple demographic and clinical factors (model p < 0.001, area under receiver operating characteristic curve = 0.85). Clinically significant contributors that increased postoperative length of stay were rectal surgery (vs colon; OR, 2.13; 95% CI, 1.52-2.98), new ileostomy (vs no ileostomy; OR, 1.50; 95% CI, 1.15-1.97), preoperative hospitalization (OR, 13.45; 95% CI, 10.15-17.84), non-home discharge (OR, 4.78; 95% CI, 2.27-10.08), hypoalbuminemia (OR, 1.66; 95% CI, 1.27-2.18), and bleeding disorder (OR, 2.42; 95% CI, 1.22-4.82). LIMITATIONS: Retrospective review of only high-volume centers. CONCLUSIONS: Patients with IBD who were preoperatively hospitalized, who had non-home discharge, and who underwent rectal surgery had the highest odds of extended postoperative length of stay. Associated patient characteristics included bleeding disorder, hypoalbuminemia, and ASA classes 3 to 5. Chronic corticosteroid, immunologic, small molecule, and biologic agent use were insignificant on multivariable analysis. See Video Abstract. IMPACTO DE LOS FACTORES PREOPERATORIOS EN PACIENTES CON ENFERMEDAD INFLAMATORIA INTESTINAL EN LA DURACIN DE LA ESTANCIA POSTOPERATORIA UN ANLISIS COLABORATIVO DEL PROGRAMA NACIONAL DE MEJORA DE LA CALIDAD QUIRRGICAENFERMEDAD INFLAMATORIA INTESTINAL: ANTECEDENTES:Los pacientes con enfermedad inflamatoria intestinal son difíciles de manejar perioperatoriamente debido a la complejidad de la enfermedad y a múltiples comorbilidades.OBJETIVO:Este estudio tuvo como objetivo identificar si los factores preoperatorios y el tipo de operación se asociaron con una estadía postoperatoria prolongada después de una cirugía relacionada con enfermedad inflamatoria intestinal, definida por el percentil 75 o mayor (n = 926, 30.8%).DISEÑO:Este fue un estudio transversal basado en una base de datos multicéntrica retrospectiva.ESCENARIO:Datos capturados de quince sitios de alto volumen en El Programa Nacional de Mejoramiento de la Calidad de la Cirugía-Enfermedad Intestinal Inflamatoria en colaboración.PACIENTES:Un total de 3,008 pacientes con enfermedad inflamatoria intestinal (1,710 con enfermedad de Crohn y 1,291 con colitis ulcerosa) con una mediana de estancia postoperatoria de 4 días (RIC 3-7) desde marzo de 2017 hasta febrero de 2020.PRINCIPALES MEDIDAS DE RESULTADO:El resultado primario fue la extensión de la estancia postoperatoria.RESULTADOS:En la regresión logística multivariable, el aumento de las probabilidades de prolongar la estancia postoperatoria se asoció con múltiples factores demográficos y clínicos (modelo p<0.001, área bajo la curva ROC - 0.85). Los contribuyentes clínicamente significativos que aumentaron la duración de la estancia postoperatoria fueron la cirugía rectal (frente al colon) (OR 2.13, IC del 95 %: 1.52 a 2.98), una nueva ileostomía (frente a ninguna ileostomía) (OR 1.50, IC del 95 %: 1.15 a 1.97), hospitalización preoperatoria (OR 13.45, IC 95% 10.15-17.84), alta no domiciliaria (OR 4.78, IC 95% 2.27-10.08), hipoalbuminemia (OR 1.66, IC 95% 1.27-2.18) y trastorno hemorrágico (OR 2.42, IC 95% 1.22-4.82).LIMITACIONES:Revisión retrospectiva de solo centros de alto volumen.CONCLUSIONES:Los pacientes con enfermedad inflamatoria intestinal que fueron hospitalizados antes de la operación, que tuvieron alta no domiciliaria y que se sometieron a cirugía rectal tuvieron las mayores probabilidades de prolongar la estancia postoperatoria. Las características asociadas de los pacientes incluyeron trastorno hemorrágico, hipoalbuminemia y clases ASA 3-5. El uso crónico de corticosteroides, inmunológicos, agentes de moléculas pequeñas y de agentes biológicos no fue significativo en el análisis multivariable. (Traducción-Dr. Jorge Silva Velazco ).

Detection of Ischemic Colitis on Routine Lower Endoscopy and Its Implications After Repair of Ruptured Abdominal Aortic Aneurysm.

BACKGROUND: Ischemic colitis (IC) is a known significant complication after repair of a ruptured abdominal aortic aneurysm (rAAA). Lower endoscopy (colonoscopy or flexible sigmoidoscopy) is a helpful adjunct to aid decision making for surgical exploration. We believe routine use of lower endoscopy after rAAA repair provides better patient care through expeditious diagnosis and surgical care. METHODS: We performed a retrospective chart review of rAAA repairs from 2008 to 2019. All patients undergo screening lower endoscopy after rAAA repair at our institution. The incidence of IC, mortality, and diagnostic characteristics of routine lower endoscopy was analyzed. RESULTS: Of these, 182 patients underwent rAAA repair, among which 139 (76%) underwent routine lower endoscopy. Ischemic colitis of any grade was diagnosed in 25% of patients. The 30-day mortality was 11% compared to 19% in those without lower endoscopy. The presence of IC portended a 4-fold increase in mortality rate compared to those without (26% vs 6%, P = .005). Surgical exploration rate was 8% after routine lower endoscopy. Grade III ischemia on lower endoscopy had a sensitivity of 50% (95% CI 12-88) and specificity of 99% (95% CI 94-100) for transmural necrosis. DISCUSSION: We found increased incidence of IC and reliable diagnostic characteristics of routine lower endoscopy in predicting the presence of transmural colonic ischemia. There was decreased mortality with use of routine lower endoscopy but this was not statistically significant.

Comparison of transversus abdominis plane catheters with thoracic epidurals for cost and length of stay in open colorectal surgeries: a cohort study.

BACKGROUND: Thoracic epidural analgesia has long been a common method of postoperative analgesia for major open abdominal surgeries and is frequently used within enhanced recovery after surgery programs. An alternative postoperative analgesia method is the single shot transversus abdominis plane block, which has shown promising outcomes with respect to total length of stay, cost, pain scores, and decreased opioid usage. However, far less is known regarding continuous transversus abdominis plane analgesia using catheters. We evaluated the total cost-effectiveness of transversus abdominis plane catheter analgesia compared to thoracic epidural analgesia for patients undergoing open colorectal surgeries within the enhanced recovery after surgery program at our institution. METHODS: This cohort study included patients booked under the colorectal surgery enhanced recovery after surgery program from November 2016 through March 2018 who received either bilateral transversus abdominis plane catheters (n = 52) or thoracic epidural analgesia (n = 24). RESULTS: There was no difference in total direct cost (p = 0.660) and indirect cost (p = 0.220), and median length of stay (p = 0.664) in the transversus abdominis plane catheter group compared to the thoracic epidural group. Additionally, the transversus abdominis plane catheter group received significantly less morphine equivalents compared to the thoracic epidural group (p = 0.008) and had a lower mean body mass index (p = 0.019). There was no significant difference between the two groups for age (p = 0.820), or sex (p = 0.330). CONCLUSIONS: Transversus abdominis plane catheter analgesia is not associated with increased cost or longer hospital stays when compared to thoracic epidural analgesia in patients undergoing open colorectal surgery within an enhanced recovery after surgery program. Furthermore, transversus abdominis plane catheter analgesia led to decreased opioid consumption while maintaining similar pain scores, suggesting similar pain control between the two modalities.

After Elective Sigmoid Colectomy for Diverticulitis, Does Recurrence-Free Mean Symptom-Free?

After elective sigmoidectomy for diverticulitis, patients may experience persistent abdominal symptoms. This study aimed to determine the incidence and characteristics of persistent symptoms (PSs) and their risk factors in patients who had no reported recurrence after elective sigmoidectomy. Patients who underwent elective sigmoidectomy for diverticulitis from 2002 to 2016 at a tertiary academic colorectal surgery practice were included. After retrospective review of medical records, patients were contacted with a questionnaire to inquire about recurrence of diverticulitis and persistent abdominal symptoms since resection. Outcomes examined were prevalence of and risk factors for PSs after elective sigmoidectomy. Of 662 included patients, 346 completed the questionnaire and had no recurrent diverticulitis. PSs were reported by 43.9 per cent of the patients. The mean follow-up was 87 months. Female gender and preoperative diagnosis of irritable bowel syndrome were independent risk factors for PSs (Relative Risk 1.65, P < 0.001 and Relative Risk 1.41, P = 0.014). Previous IV antibiotics treatment was associated with PSs (P = 0.034) but not with a significant risk factor. As the follow-up interval increased, prevalence of PSs decreased (P = 0.006). More than 40 per cent of patients experienced persistent abdominal symptoms after sigmoidectomy for diverticulitis. Female patients and those with irritable bowel syndrome were at significantly increased risk.

Gastrointestinal Diaphragm Disease With Retained Capsule Endoscope, Associated With Crohn's Disease: A Case Report.

Gastrointestinal diaphragm disease is a rare entity characterized by the formation of thin membranous circumferential mucosal septa, resulting in marked narrowing of the intestinal lumen. The most frequent etiology is the chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs). Idiopathic cases and other possible etiologies have been reported. We present a rare association of diaphragm disease with Crohn's disease in a boy without a history of significant NSAID usage.

Laparoscopic Surgery for Diverticular Fistulas: Outcomes of 111 Consecutive Cases at a Single Institution.

BACKGROUND: The purpose of this study was to review our experience with laparoscopic colectomy and fistula resection, evaluate the frequency of conversion to open, and to compare the perioperative courses of the complete laparoscopic and conversion groups. METHODS: This study is a retrospective analysis of 111 consecutive adult patients with diverticular fistulae diagnosed clinically or radiographically over 11 years at a single institution. Five patients were excluded for preoperative comorbidities. The remaining 106 consecutive patients underwent minimally invasive sigmoid colectomy with primary anastomosis. Preoperative, intraoperative, and postoperative variables were collected from the colorectal surgery service database. A retrospective cohort analysis was performed between laparoscopic and converted groups. RESULTS: Within the group, 47% had colovesical fistulas, followed by colovaginal, coloenteric, colocutaneous, and colocolonic fistulas. The overall conversion rate to laparotomy was 34.7% (n = 37). The most common reason for conversion was dense fibrosis. Mean operative time was similar between groups. Combined postoperative complications occurred in 26.4% of patients (21.4% laparoscopic and 37.8% converted, p = 0.075). Length of stay was significantly shorter in the laparoscopic group (5.8 vs 8.1 days, p = 0.014). There were two anastomotic leaks, both in the open group. There were no 30-day mortalities. CONCLUSIONS: Laparoscopic sigmoid colectomy for diverticular fistula is safe, with complication rates comparable to open sigmoid resection. We identify a conversion rate which allows the majority of patients to benefit from minimally invasive procedures.

Impact of Interhospital Transfer on Outcomes in Non-emergency Colorectal Surgery.

BACKGROUND: A paucity of data exists on the impact of transfer status on outcomes for patients undergoing non-emergency (urgent) colorectal surgery. This study characterized transferred patients undergoing urgent colorectal surgery and determined which patient comorbidities significantly contributed to poor outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2013 was used. Urgent direct admissions undergoing colon, rectum, or small bowel operations were compared to urgent transfers using bivariate and multivariable analysis models. Primary outcomes were overall complications, hospital length of stay, and mortality. RESULTS: A total of 82,151 admissions were analyzed. After multivariable analysis, direct admission patients had nearly similar risk of complications (RR = 0.95; 95% CI 0.91-0.99) and length of hospital stay (7% shorter; 95% CI 4-9%), as well as no difference in mortality (RR = 0.94; 95% CI 0.80-1.11). CONCLUSIONS: Transfer status alone confers minimal risk toward higher complication rates and longer hospital length of stay in patients undergoing urgent colorectal surgery, and the poor outcomes observed in this cohort are largely due to patient comorbidities and disease severity. Our results suggest that outcomes in transferred colorectal surgery patients undergoing urgent operations depend mainly on operative acuity and clinical factors, and to a lesser degree transfer status.

Complications and surgical outcomes after interhospital transfer vs direct admission in colorectal surgery: A National Surgical Quality Improvement Program analysis.

BACKGROUND: Interhospital transfer is common among patients undergoing colorectal surgery. The purpose of this study was to determine surgical outcomes after transfer vs direct admission in patients undergoing colorectal surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2012 was used. Colorectal operations were selected, including both emergency and nonemergency cases. Transfers were compared with direct admissions using a complex comorbidity analysis model. Primary outcomes of interest were mortality, extended hospital length of stay, and complication rates. RESULTS: The study included 121,040 admissions. After adjusting for multiple patient factors and comorbidities, nonemergency transfers still had higher mortality rates (RR = 1.20; P < .05), longer length of hospital stay (RR = 1.24; P < .05), and higher complication rates (RR = 1.18; P < .05). CONCLUSIONS: Preoperative hospital transfer is common among patients requiring colorectal surgery. Despite extensive propensity score matching, nonemergency transfers have higher rates of mortality, longer length of hospital stay, and higher overall complication rates compared with direct admissions. Transfer status is an important variable in hospital performance models and should be taken into consideration when analyzing hospital outcomes.

Increased Incidence of Surgical Site Infection in IBD Patients.

BACKGROUND: Surgical site infection is a key hospital-level patient safety indicator. All risk factors for surgical site infection are not always taken into account and adjusted for. OBJECTIVE: This study aimed to measure the impact of IBD in comparison with diverticulitis and colorectal cancer on the national rates of surgical site infection. DESIGN: The American College of Surgeons National Surgical Quality Improvement Project database was queried for all patients undergoing elective colectomy for colon cancer, diverticulitis, and IBD from 2008 through 2012. OUTCOME MEASURES: The association between surgical site infection and IBD patients was assessed. Patient demographics, rates of surgical site infection, wound class, return to operating room, and various patient characteristics were analyzed. Logistic regression was performed to determine the association with surgical site infection. RESULTS: The query yielded 71,845 patients undergoing elective colectomy. Of these patients, 42,132 had colon cancer, 22,143 had diverticulitis, and 7570 had IBD. The rate of surgical site infection was 12.0% for colon cancer, 12.8% for diverticulitis, and 18.0% for IBD. Return to operating room within 30 days was 7.3% for IBD patients, 4.4% for patients with diverticulitis, and 4.9% for patients with colorectal cancer. Return to operating room within 30 days had the highest correlation to surgical site infection in both univariate and multivariable analysis. Other associative factors for surgical site infection common to both analyses included diabetes mellitus, smoking, open procedures, and obesity. LIMITATIONS: This study was limited by the data collection errors inherent to large databases, exclusion of emergent operations, and the inability to identify patients taking immunosuppressive agents. CONCLUSIONS: Patients with IBD undergoing elective colectomy have significantly increased rates of surgical site infection, specifically deep and organ/space infections. Given this information, risk adjustment models for surgical site infection may need to include IBD in their calculation.

Laparoscopic sigmoid colectomy for complicated diverticulitis is safe: review of 576 consecutive colectomies.

INTRODUCTION: Laparoscopic resection of diverticular disease is typically offered to selected patients. We present the outcomes of laparoscopic colectomy in consecutive patients suffering from either simple diverticulitis (SD) or complicated diverticulitis (CD). PURPOSE: To examine the outcomes of laparoscopic sigmoid colectomy for complicated diverticulitis. METHODS: Between December 2001 and May 2013, all patients with diverticulitis requiring elective operation were offered laparoscopic sigmoid colectomy as the initial approach. All cases were managed at a large tertiary care center on the colorectal surgery service. Preoperative, intraoperative, and postoperative variables were prospectively entered into the colorectal surgery service database (CRSD) and analyzed retrospectively. RESULTS: Of the 576 patients in the CRSD, 139 (24.1%) had CD. The overall conversion rate was 12.8% (n = 74). The average BMI was 29.8 kg/m(2). The conversion rate for CD was 12.2%. The return of bowel function time was delayed in the CD group when compared to the SD group (3.1 vs 3.8 days, p = 0.04). The hospital length of stay (HLOS) was similar between the groups (5.1 vs 5.8 days, p = 0.08). The overall anastomotic leak rate was 2.1% (n = 12). Patients undergoing laparoscopic resection for SD had a postoperative complication rate of 10.0% (n = 38), whereas those with CD had a postoperative morbidity rate of 19.6% (n = 24). CD patients who had conversion to an open procedure had an even higher rate of postoperative complications (29.4%, n = 5, p = 0.35). On non-parsimonious multivariate adjustment, only CD (RR 1.96, 95% CI 1.11-3.46, p = 0.02) was found to be an independent risk factor for the development of postoperative complications. CONCLUSIONS: Complicated diverticulitis did not affect the conversion rate to an open procedure. However, patients with CD are prone to postoperative complications. The laparoscopic approach to sigmoid colectomy is safe and preferable in experienced hands.

Incidence of Ostomy Site Incisional Hernias after Stoma Closure.

This study sought to evaluate the incidence of ostomy site incisional hernias after stoma reversal at a single institution. This is a retrospective analysis from 2001 to 2011 evaluating the following demographics: age, gender, indication for stoma, urgent versus elective operation, time to closure, total follow-up time, the incidence of and reoperation for stoma incisional hernia, diabetes, postoperative wound infection, smoking status within six months of surgery, body mass index, and any immunosuppressive medications. A total of 365 patients were evaluated. The median follow-up time was 30 months. The clinical hernia rate was 19 percent. Significant risk factors for hernia development were age, diabetes, end colostomies, loop colostomies, body mass index >30, and undergoing an urgent operation. The median time to clinical hernia detection was 32 months. Sixty-four percent of patients required surgical repair of their stoma incisional hernia. A significant number of patients undergoing stoma closure developed an incisional hernia at the prior stoma site with the majority requiring definitive repair. These hernias are a late complication after stoma closure and likely why they are under-reported in the literature.
