A New Bibliometric Index: The Top 100 Most Disruptive and Developmental Publications in Colorectal Surgery Journals.

BACKGROUND: A new bibliometric index called the disruption score was recently proposed to identify innovative and paradigm-changing publications. OBJECTIVE: The goal was to apply the disruption score to the colorectal surgery literature to provide the community with a repository of important research articles. DESIGN: This study is a bibliometric analysis. SETTINGS: The 100 most disruptive and developmental publications in Diseases of the Colon & Rectum, Colorectal Disease, International Journal of Colorectal Disease, and Techniques in Coloproctology were identified from a validated data set of disruption scores and linked with the iCite National Institutes of Health tool to obtain citation counts. MAIN OUTCOME MEASURES: The primary outcomes measured were the disruption score and citation count. RESULTS: We identified 12,127 articles published in Diseases of the Colon & Rectum (n = 8109), International Journal of Colorectal Disease (n = 1912), Colorectal Disease (n = 1751), and Techniques in Coloproctology (n = 355) between 1954 and 2014. Diseases of the Colon & Rectum had the most articles in the top 100 most disruptive and developmental lists. The disruptive articles were in the top 1% of the disruption score distribution in PubMed and were cited between 1 and 671 times. Being highly cited was weakly correlated with high disruption scores (r = 0.09). Developmental articles had disruption scores that were more strongly correlated with citation count (r = 0.18). LIMITATIONS: This study is subject to the limitations of bibliometric indices, which change over time. DISCUSSION: The disruption score identified insightful and paradigm-changing studies in colorectal surgery. These studies include a wide range of topics and consistently identified editorials and case reports/case series as important research. This bibliometric analysis provides colorectal surgeons with a unique archive of research that can often be overlooked but that may have scholarly significance.

Keep Them on the Table: Outcomes Are Improved After Minimally Invasive Colectomy Despite Longer Operative Times in Patients With High-Risk Colon Cancer.

BACKGROUND: For high-risk patients, traditional surgical dogma advises open operations, with short operative times, to "get them off the table" instead of longer minimally invasive surgery approaches. OBJECTIVE: The aim of this study was to compare postoperative outcomes in patients with high-risk colon cancer undergoing elective longer minimally invasive surgery operations compared with shorter open operations. DESIGN: Retrospective comparative cohort study. SETTINGS: Interventions were performed in hospitals participating in the national surgical database. PATIENTS: The National Surgical Quality Improvement Program database was used to identify patients with colon cancer with ASA class 3 to 4 undergoing right and sigmoid colectomy between 2012 and 2017. MAIN OUTCOME MEASURES: Thirty-day postoperative outcomes were compared between short open and long minimally invasive groups. RESULTS: A total of 3775 patients were identified as having undergone long minimally invasive right colectomy and short open right colectomy (33% open, 67% minimally invasive surgery), and 1042 patients were identified as having undergone long minimally invasive sigmoid colectomy and short open sigmoid colectomy (36% open, 64% minimally invasive). Patients undergoing long minimally invasive right colectomy had significantly lower rates of overall morbidity, severe adverse events, mortality, superficial surgical site infections, and wound disruptions, as well as discharge to a higher level of care and shorter length of stay ( p < 0.05). Patients undergoing long minimally invasive sigmoid colectomy had decreased rates of overall morbidity, severe adverse events, and length of stay, as well as discharge to a higher level of care compared with the patients undergoing short open sigmoid colectomy ( p < 0.05). LIMITATIONS: This study was limited by the retrospective nature and standardized outcome measures. CONCLUSIONS: In high-risk patients undergoing colectomy for colon cancer, outcomes were worse with shorter open compared with longer minimally invasive surgery operations. Focus should shift from getting patients "off the table" faster to longer, but safer, minimally invasive surgery in high-risk patients. See Video Abstract at http://links.lww.com/DCR/B642 . MANTNGALOS SOBRE LA MESA HAY MEJORES RESULTADOS DESPUS DE COLECTOMA MNIMAMENTE INVASIVA A PESAR DE TIEMPOS QUIRRGICOS MS PROLONGADOS EN PACIENTES CON CNCER DE COLON DE ALTO RIESGO: ANTECEDENTES:Para los pacientes de alto riesgo, el dogma quirúrgico tradicional aconseja operaciones abiertas, con tiempos quirúrgicos cortos, con el fin de "sacarlos de la mesa" en lugar de enfoques quirúrgicos mínimamente invasivos más prolongados.OBJETIVO:El objetivo de este estudio fue comparar los resultados posoperatorios en pacientes electivos de cáncer de colon de alto riesgo sometidos a operaciones de cirugía mínimamente invasiva más prolongadas en comparación con operaciones abiertas más cortas.DISEÑO:Los resultados posoperatorios de pacientes con cáncer de colon con clase 3-4 de la Sociedad Americana de Anestesiología sometidos a colectomía derecha o sigmoidea se compararon en un análisis multivariado. Se comparó el grupo de colectomía derecha abierta corta (tiempo operatorio <116 minutos) y colectomía derecha mínimamente invasiva larga (tiempo operatorio> 132 minutos). También se compararon la colectomía sigmoidea abierta corta (tiempo operatorio <127 minutos) y la colectomía sigmoidea mínimamente invasiva larga (tiempo operatorio> 161 minutos).ESCENARIO:Las intervenciones se realizaron en hospitales participantes en la base de datos quirúrgica nacional.PACIENTES:La base de datos del Programa Nacional de Mejoramiento de la Calidad Quirúrgica se utilizó para identificar a los pacientes con cáncer de colon con clase 3-4 de la Sociedad Americana de Anestesiología sometidos a colectomía derecha y sigmoidea entre 2012-2017.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon los resultados posoperatorios a los treinta días entre el grupo de procedimientos abiertos cortos y el de mínimamente invasivos largos.RESULTADOS:Se identificó un total de 3.775 pacientes sometidos a colectomía derecha mínimamente invasiva larga y colectomía derecha abierta corta (33% abierta, 67% cirugía mínimamente invasiva) y se identificaron 1042 pacientes sometidos a colectomía sigmoidea mínimamente invasiva larga y colectomía sigmoidea abierta corta (36% abierta, 64% mínimamente invasiva). Los pacientes con colectomía derecha larga mínimamente invasiva tuvieron significativamente menor morbilidad general, eventos adversos graves, mortalidad, infecciones superficiales del sitio quirúrgico, dehiscencia de herida, alta a un nivel más alto de atención y estadía más corta ( p <0.05). Los pacientes con colectomía sigmoidea mínimamente invasiva prolongada tuvieron menor morbilidad general, eventos adversos graves, duración de la estadía y alta a un nivel más alto de atención en comparación con los pacientes con colectomía sigmoidea abierta corta ( p <0.05).LIMITACIONES:Este estudio estuvo limitado por la naturaleza retrospectiva y las medidas de resultado estandarizadas.CONCLUSIONES:En los pacientes de alto riesgo sometidos a colectomía por cáncer de colon, los resultados fueron peores con operaciones abiertas más cortas en comparación con operaciones mínimamente invasivas más largas. El enfoque debe pasar de hacer que los pacientes "salgan rápido de la mesa quirúrgica" a una cirugía mínimamente invasiva más prolongada pero más segura, en pacientes de alto riesgo.

Surgical Residents' Perspective on Informed Consent-How Does It Compare With Attending Surgeons?

BACKGROUND: The informed consent discussion (ICD) is a compulsory element of clinical practice. Surgical residents are often tasked with obtaining informed consent, but formal instruction is not included in standard curricula. This study aims to examine attitudes of surgeons and residents concerning ICD. MATERIALS AND METHODS: A survey regarding ICD was administered to residents and attending surgeons at an academic medical center with an Accreditation Council for Graduate Medical Education-accredited general surgery residency. RESULTS: In total, 44 of 64 (68.75%) residents and 37 of 50 (72%) attending surgeons participated. Most residents felt comfortable consenting for elective (93%) and emergent (82%) cases, but attending surgeons were less comfortable with resident-led ICD (51% elective, 73% emergent). Resident comfort increased with postgraduate year (PGY) (PGY1 = 39%, PGY5 = 85%). A majority of participants (80% attending surgeons, 73% residents) believed resident ICD skills should be formally evaluated, and most residents in PGY1 (61%) requested formal instruction. High percentages of residents (86%) and attendings (100%) believed that ICD skills were best learned from direct observation of attending surgeons. CONCLUSIONS: Resident comfort with ICD increases as residents advance through training. Residents acknowledge the importance of their participation in this process, and in particular, junior residents believe formal instruction is important. Attending surgeons are not universally comfortable with resident-led ICDs, particularly for elective surgeries. Efforts for improving ICD education including direct observation between attending surgeons and residents and formal evaluation may benefit the residency curriculum.

It Takes a Village: The First 100 Patients Seen in a Multidisciplinary Pelvic Floor Clinic.

OBJECTIVE: This study aimed to assess the characteristics of patients assessed and treated at a multidisciplinary pelvic floor program that includes representatives from multiple specialties. Our goal is to describe the process from triaging patients to the actual collaborative delivery of care. This study examines the factors contributing to the success of our multidisciplinary clinic as evidenced by its ongoing viability. METHODS: This is a descriptive study retrospectively analyzing a prospectively maintained database that included the first 100 patients seen in the Program for Abdominal and Pelvic Health clinic between December 2017 and October 2018. We examined patient demographics, their concerns, and care plan including diagnostic tests, findings, treatments, referrals, and return visits. RESULTS: The clinic met twice monthly, and the first 100 patients were seen over the course of 10 months. The most common primary symptoms were pelvic pain (45), constipation (30), bladder incontinence (27), bowel incontinence (23), high tone pelvic floor dysfunction (23), and abdominal pain (23); most patients had more than one presenting symptom (76). The most common specialties seen at the first visit to the clinic included gastroenterology (56%), followed by physical medicine and rehabilitation (45%), physical therapy (31%), female pelvic medicine and reconstructive surgery (25%), behavioral health (19%), urology (18%), and colorectal surgery (13%). Eleven patients were entirely new to our hospital system. Most patients had diagnostic tests ordered and performed. CONCLUSIONS: A multidisciplinary clinic for abdominal and pelvic health proves a sustainable model for comprehensive treatment for patients with pelvic floor dysfunction, including difficulties with defecation, urination, sexual dysfunction, and pain.

I want to go home: should we abandon open surgery for treatment of rectal prolapse? Consideration of discharge destination following surgery for rectal prolapse.

AIM: Despite the financial and value-based implications associated with higher levels of care at discharge, few studies have evaluated modifiable treatment factors that may optimize postacute care. The aim of this work was to assess the association between operative approach and disposition to a higher level of care and other outcomes following surgery for rectal prolapse. METHOD: Using a retrospective cohort study design, the database of the National Surgical Quality Improvement Program was used to identify patients with rectal prolapse who underwent perineal repair or open or laparoscopic rectopexy with or without resection between 2012 and 2017. Discharge destination and 30-day postoperative outcomes were compared using propensity score mathcing and weighting. Nomograms generated using multivariable regression calculated the risk of requiring higher levels of care upon discharge and morbidity. RESULTS: Propensity-score analysis included 3000 patients [1500 in the perineal group, 580 in the open abdominal group and 920 in the minimally invasive (MIS) group]. Patients who received open abdominal surgery were more likely to require elevation of care at destination compared with those who received perineal surgery (OR 1.65, 95% CI 1.22-1.24) and MIS abdominal surgery (OR 1.80, 95% CI 1.18-2.76). Similar effects were seen for overall morbidity. Increased age, higher American Society of Anesthesiologists class, congestive heart failure, dependent functional status and open surgery were independent predictors of discharge to higher level of care (c-statistic = 0.79). CONCLUSION: Open surgery compared with MIS and perineal surgery was associated with higher levels of discharge disposition following rectal prolapse surgery. Future research should continue to identify modifiable treatment factors that reduce poor postoperative outcomes among patients with rectal prolapse.

Early feeding in colorectal surgery patients: safe and cost effective.

PURPOSE: Enhanced recovery after surgery (ERAS) pathways has demonstrated improved outcomes in colorectal surgery. An important component of ERAS is early oral intake. The aim of this study is to determine the impact of early oral intake in patients following colorectal surgery. METHODS: A retrospective analysis of patients who underwent colectomy and proctectomy at an academic institution from January 2015 to November 2018 was performed. Postoperative outcomes were compared between patients who had postoperative day 0 (POD 0) oral intake and those who did not. RESULTS: A total of 436 ERAS patients had oral intake timing documented. The majority of patients were women (241, 55.3%) and white (313, 71.8%). The mean age was 57 ± 15.09. Patients who had early intake were found to have lower 30-day overall morbidity and length of stay (p < 0.05), and no difference in serious adverse events. Additionally, hospital costs were lower in the POD 0 feeding group for all patients (p < 0.05). CONCLUSION: We have demonstrated that early oral feeding in an established ERAS pathway is associated with improved clinical outcomes as well as decreased total hospital costs. Early postoperative feeding is safe in colorectal patients and should be prioritized to decrease complications and healthcare costs.

A national analysis of operative treatment of adult patients with Hirschsprung's disease.

PURPOSE: Hirschsprung's disease is primarily a disease of infancy, but in rare cases, adults with this condition require surgery. The aim of this study is to identify the types of operations and postoperative outcomes in adults with Hirschsprung's disease on a national level. METHODS: The National Surgical Quality Improvement Program database was used to perform a retrospective review of all adult patients diagnosed with Hirschsprung's disease. Patients were divided into two groups depending on the type of operation: restoration of bowel continuity or diversion of fecal stream; clinicopathologic data and 30-day outcomes were compared between the two groups. RESULTS: A total of 32 patients were analyzed. Fourteen patients (43.8%) underwent diversion and 18 (56.2%) underwent restorative procedures. The median age was 49.5 years old for the diversion group and 23.5 years old for the reconstructive group (p = 0.001). The restorative surgery group was more likely to have an ASA 1-2 while the diversion group had a higher frequency of ASA 3-5 (p = 0.011). The median length of stay for the diversion surgery was 9.5 days and 5 days for the restoration group (p = 0.045). Complications occurred in 57% of patients in the diversion group and in 22% of patients in the restoration group (p = 0.049). There were otherwise no statistically significant differences in intraoperative data and postoperative complications. CONCLUSION: This is the first study using a national database to evaluate the surgical treatment of Hirschsprung's disease in adult patients. Complications are common and were more frequent in the older, sicker diversion group, with restoration of continuity being better tolerated in the younger, healthier patient population.

Patient factors may predict anastomotic complications after rectal cancer surgery: Anastomotic complications in rectal cancer.

PURPOSE: Anastomotic complications following rectal cancer surgery occur with varying frequency. Preoperative radiation, BMI, and low anastomoses have been implicated as predictors in previous studies, but their definitive role is still under review. The objective of our study was to identify patient and operative factors that may be predictive of anastomotic complications. METHODS: A retrospective review was performed on patients who had sphincter-preservation surgery performed for rectal cancer at a tertiary medical center between 2005 and 2011. RESULTS: 123 patients were included in this study, mean age was 59 (26-86), 58% were male. There were 33 complications in 32 patients (27%). Stenosis was the most frequent complication (24 of 33). 11 patients required mechanical dilatation, and 4 had operative revision of the anastomosis. Leak or pelvic abscess were present in 9 patients (7.3%); 4 were explored, 2 were drained and 3 were managed conservatively. 4 patients had permanent colostomy created due to anastomotic complications. Laparoscopy approach, BMI, age, smoking and tumor distance from anal verge were not significantly associated with anastomotic complications. After a multivariate analysis chemoradiation was significantly associated with overall anastomotic complications (Wall = 0.35, p = 0.05), and hemoglobin levels were associated with anastomotic leak (Wald = 4.09, p = 0.04). CONCLUSION: Our study identifies preoperative anemia as possible risk factor for anastomotic leak and neoadjuvant chemoradiation may lead to increased risk of complications overall. Further prospective studies will help to elucidate these findings as well as identify amenable factors that may decrease risk of anastomotic complications after rectal cancer surgery.

Are our publications failing the inspection?: a review of the publications in rectal cancer surgery between 2002 and 2012.

BACKGROUND: Quality of publications is considered a subjective measurement, and more weight is placed on prospective studies, especially randomized clinical trials and meta-analyses. OBJECTIVE: This study describes the type of publications and evaluates the quality of randomized clinical trials and review articles using an objective measurement. DATA SOURCES: Medline (PubMed) is the data source for this work. STUDY SELECTION: We used the terms "rectal neoplasms/surgery" and the filters "10 years," "humans," and "English." MAIN OUTCOME MEASURES: We measured compliance with checklist items. Randomized clinical trials were reviewed using the Consolidates Standards of Reporting Trials statement; systematic reviews/meta-analyses were reviewed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS: A total of 3603 articles were identified: 20.8% were case report/series, 20.5% were retrospective cohorts, 14.0% were reviews or meta-analyses, 16.4% were prospective cohorts, 14.0% were other types of articles (comments, letters, or editorials), 5.5% were clinical trials (phase I/II), 4.2% were randomized clinical trials, and 4.4% were cross-sectional studies. We reviewed 108 randomized clinical trials; the maximum score possible was 74.0, the average score was 44.6 (range, 20.0-64.0), 4 (3.7%) were graded as "excellent," 21 (19.4%) were "good," 44 (40.7%) were "deficient," and 39 (36.1%) were graded as "fail." The predictors of higher scores for randomized clinical trials were year of publication after 2007 (p = 0.00), higher impact factor (p = 0.03), and declared funding (p = 0.01). Twenty-nine meta-analyses were reviewed; the average score was 19.64 (range, 12.0-25.0); 5 articles (17.2%) were graded as "excellent," 12 (41.4%) were "good," 10 (34.5%) were "deficient," and 2 (6.9%) were "fail." LIMITATIONS: Only 1 electronic database was used, so we lacked a validated score. In addition, the search terms did not include "colorectal." CONCLUSIONS: A total of 20.8% of the articles published were case reports and 25.0% of the articles were prospective or clinical trials. Although randomized clinical trials and systematic reviews provide the highest level of evidence, publications with missing data limit replication of the study and affect the generalizability of results to other populations. To improve the quality of our publications, authors, reviewers, and journal editors should consider the endorsement of standardize checklists.

Hospital readmission for fluid and electrolyte abnormalities following ileostomy construction: preventable or unpredictable?

BACKGROUND: Ileostomy creation has complications, including rehospitalization for fluid and electrolyte abnormalities. Although studies have identified predictors of this morbidity, readmission rates remain high. METHODS: The researchers conducted a retrospective chart review of all patients with ileostomy creation at a tertiary institution from January 2008 to June 2011. RESULTS: One hundred fifty-four patients (154) were included in this study; 71 (46.1 %) were female. Mean age was 49 ± 17.64 (range 16-91), and mean BMI was 26.9 ± 6.44 (range 13-52). The readmission rate for fluid and electrolyte abnormalities was 20.1 % for the study population; of those readmitted for all diagnoses, dehydration accounted for 40.7 % of all readmissions. Cancer was associated with readmission (χ(2) = 4.73, p = 0.03) as was neoadjuvant therapy (χ(2) = 9.20, p = 0.01). After multivariate analysis, only the use of anti-diarrheals and neoadjuvant therapy remained significant. High stoma output, adjuvant treatment, and postoperative complications were not significant. CONCLUSIONS: Our study found that the use of anti-diarrheals and neoadjuvant therapy for rectal cancer were associated with readmission. Our findings imply that the use of anti-diarrheals may be a marker for patients at risk for fluid and electrolyte abnormalities; these patients should be strictly monitored at home. Our study also suggests consideration of avoidance of ileostomy creation or different discharge criteria for at-risk patients. Prospective studies focused on stoma monitoring after discharge may help reduce rehospitalizations for fluid and electrolyte abnormalities after ileostomy creation.

Tumor scatter after neoadjuvant therapy for rectal cancer: are we dealing with an invisible margin?

BACKGROUND: After the impressive response of rectal cancers to neoadjuvant therapy, it seems reasonable to ask: can we can excise the small ulcer locally or avoid a radical resection if there is no gross residual tumor? Does gross response reflect what happens to tumor cells microscopically after radiation? OBJECTIVE: The aim of this study was to identify microscopic tumor cell response to radiation. DESIGN: This study is a retrospective review of a prospectively collected database. SETTING: This investigation was conducted at a single tertiary medical center. PATIENTS: Patients were selected who had elective radical resection for rectal cancer after preoperative chemotherapy and radiation performed by 2 colorectal surgeons between 2006 and 2011. MAIN OUTCOME MEASURES: The primary outcome measured was tumor presence after radiation therapy RESULTS: Of the 75 patients, 20 patients were complete responders and 55 had residual cancer. Of these patients, 28 had no tumor cells seen outside the gross ulcer, and 27 (49.1%) had tumor outside the visible ulcer or microscopic tumor present with no overlying ulcer. Of these tumors, 81.5% were skewed away from the ulcer center. The mean distance of distal scatter was 1.0 cm from the visible ulcer edge to a maximum of 3 cm; 3 patients had tumor cells more than 2 cm distal to the visible ulcer edge. Tumor scatter outside the ulcer was not associated with poor prognostic factors, such as nodal and distant disease, perineural invasion, or mucin; however, it was associated with lymphovascular invasion (χ2 = 4.12, p = 0.038) LIMITATIONS: There was limited access to clinical information gathered outside our institution. CONCLUSIONS: Our study suggests that 1) after radiation, the gross ulcer cannot be used to determine the sole area of potential residual tumor, 2) cancer cells may be found up to 3 cm distally from the gross ulcer, so the traditional 2-cm margin may not be adequate, and 3) local excision of the ulcer or no excision after apparent complete response appears to be insufficient treatment for rectal cancer.

Surgery after colonic stenting.

Colonic stenting is an accepted treatment of large bowel obstruction. The literature is sparse regarding surgical difficulties associated with an indwelling stent. We report our experience focusing on outcomes, complications, and whether the stent created intraoperative concerns. In this retrospective review, 6 patients were identified between 2007 and 2010 that had surgery after colonic stents were placed. Their charts were reviewed to compare clinical variables, surgical procedures, outcomes, and complications. One obstruction was due to diverticulitis. The stent reobstructed, leading to emergent transverse loop colostomy, and subsequent sigmoidectomy with stoma reversal. Four patients' obstructing masses were malignant. The final patient's stent was placed through a Hartmann's stump to drain a pelvic abscess. These 5 patients had no stent complications. Surgery occurred an average of 9.8 weeks after stent placement; four had low anterior resections and one underwent Hartmann's reversal. All 6 patients had colorectal anastomoses and five underwent laparoscopic surgery; one had an anastomotic leak requiring reoperation. Colonic stenting allows for the immediate relief of obstruction while permitting diagnosis and treatment of coexisting medical problems. The colon can be prepared for an elective rather than emergency operation, and a colostomy may be avoided.

Incisionless laparoscopic total proctocolectomy with ileal J-pouch anal anastomosis.

Minimally invasive surgery continues to evolve. Recent innovations have included single-incision access, robotic technology, and natural orifice dissection and/or specimen extraction. Many argue that there is minimal patient benefit to these advanced techniques. We report 39 patients undergoing laparoscopic ileal J-pouch anal anastomosis surgery, 17 of whom did not have a separate specimen extraction incision (Group 1). The specimen for this group was extracted through the circular incision made for the ileostomy; the pouch was constructed extracorporeally and returned to the abdomen through the stoma site. For the remaining 22 patients, a suprapubic Pfannenstiel incision was made (Group 2). No hand-assistance was used for either group. Group 1 showed a 45-minute reduction in operative time, a 1-day reduction in hospital stay, and a reduction in complications. Although these differences are modest, it shows that minimally invasive surgery is an evolving process. Small modifications may translate into significant advantages.

Laparoscopic colectomy: complications causing reoperation or emergency room/hospital readmissions.

The purpose of this study was to determine the incidence of complications causing reoperation or emergency room(ER)/hospital readmission after laparoscopic colectomy (LC). We retrospectively reviewed a prospectively managed database of 358 patients undergoing LC. Nonhand assisted LC was jointly performed by two surgeons assisted by a general surgery resident. Trochar site fascial wounds larger than 5 millimeters were not closed for the first 283 cases, mesenteric defects were not closed. Forty-one patients (11%) required reoperation. Of the 19 hernias (17 incisional, 2 mesenteric), seven caused early postoperative obstructions either within the first week of surgery or within 4 days after discharge. Twelve hernias presented in a delayed fashion and were repaired months later. Eight hernias occurred at trochar sites, nine at specimen extraction sites, and two were in the mesenteric defect. There were eight adhesive small bowel obstructions, five were treated with early reoperation. Other causes included perforations in six cases (2%), anastomotic leak in seven cases (2%) and bleeding in two cases (0.5%). Fifty-nine (16%) separate patients required evaluation in the ER. Fifty-three patients had one ER visit, six patients had two. Causes included nausea and vomiting in 19 cases (5%), wound infection in 16 cases (4%), pain in 13 cases (4%), fever in five cases (1%), thrombosis in four cases (1%); 46 were admitted to the hospital, 70 per cent were discharged within 4 days. Eleven per cent of patients required reoperation after LC, usually for hernias or adhesive small bowel obstruction. Fifty-three per cent of the hernias could have been avoided by routine closure of the fascia. An additional 16 per cent of patients required ER evaluation for complications. Of these, 78 per cent were admitted, 70 per cent were discharged within 4 days. LC is not without potential complications and is not necessarily a less morbid operation.

Endobronchial colorectal metastasis versus primary lung cancer: a tale of two sleeve right upper lobectomies.

Endobronchial metastasis from colorectal carcinoma is relatively uncommon whereas primary bronchogenic carcinoma is more common. These two disease entities can both appear to be similar clinically and radiographically. Palliative treatment rather than a curative-intent anatomic resection is typically employed in the setting of endobronchial metastatic disease. We compare two cases of patients with a history of colorectal carcinoma with endobronchial lesions of which one was truly a metastatic lesion.

Morbidity and mortality in octogenarians and older undergoing major intestinal surgery.

PURPOSE: The elderly constitute an increasing portion of the world's population. Our study assessed morbidity, mortality, and outcome in octogenarians who have undergone lower intestinal operations, and compared outcome between subsequent decades. METHODS: A total of 138 octogenarians who underwent 157 operations were retrospectively studied (1995-2005). The American Society of Anesthesiologists Physical Status classification, blood loss, length of surgery, surgical intensive care unit admission, length of surgical intensive care unit and hospital stay, and complications were recorded. Emergency vs. elective and cancer vs. noncancer cases were compared. Results were compared for the years 1985 to 1994. RESULTS: Cancer comprised 63 percent of cases. The most common causes of mortality were sepsis and multiorgan failure. Differences (P < 0.05) were found for elective vs. emergent surgeries according to age, length of stay, complications, surgical intensive care unit admission, American Society of Anesthesiologists Physical Status classification, and mortality. Noncancer cases were more likely to be emergent, have a higher American Society of Anesthesiologists Physical Status classification, and a higher mortality rate. When emergency operations were excluded, there were no significant differences between cancer vs. noncancer cases. In a comparison of two decades (1985-1994 vs. 1995-2005), we found that the mortality rate in patients younger than aged 85 years decreased by more than 10 percent (P < 0.05). Patients older than aged 85 years demonstrated no significant differences between decades. The strongest determinants of outcome are emergency status and the presence of comorbid conditions. CONCLUSIONS: Elective surgery in the elderly is safe. Emergency surgery is accompanied by significant morbidity and mortality.
