Cadaveric Study of Colon Lengthening Maneuvers Following Sigmoidectomy.

BACKGROUND: Creation of a tension free colorectal anastomosis after left colon resection or low anterior resection is a key requirement for technical success. The relative contribution of each of a series of known lengthening maneuvers remains incompletely characterized. OBJECTIVE: The aim of this study was to compare technical procedures for lengthening of the left colon prior to rectal anastomosis. DESIGN: A series of lengthening maneuvers was performed on 15 fresh cadavers. Average distance gained was measured for each successive maneuver, including (1) high inferior mesenteric artery ligation, (2) splenic flexure takedown, and (3) high inferior mesenteric vein ligation by the ligament of Treitz. SETTING: Cadaveric study. MAIN OUTCOME MEASURES: The pre-mobilization and post-mobilization position of the proximal colonic end was measured relative to the inferior edge of the sacral promontory. Measurements of the colonic length relative to the sacral promontory were taken following each mobilization maneuver. The inferior mesenteric artery, sigmoid colon and rectum specimen lengths were measured. The distance from the inferior border of the sacral promontory to the pelvic floor was measured along the sacral curvature. RESULTS: Average sigmoid colon resection length was 34.7 ± 11.1 cm. Prior to any lengthening, baseline reach was -1.3 ± 4.2 cm from the sacral promontory. Inferior mesenteric artery ligation yielded an additional 11.5 ± 4.7 cm. Subsequent splenic flexure takedown added an additional 12.8 ± 9.6 cm. Finally, inferior mesenteric vein ligation added an additional 11.33 ± 6.9 cm, bringing the total colonic length to 35.7 ± 14.7 cm. BMI and weight negatively correlated with length gained. LIMITATIONS: The study was limited by nature of being a cadaver study. CONCLUSIONS: Stepwise lengthening maneuvers allow significant additional reach to allow a tension free left colon to rectal anastomosis. See Video Abstract.

Pathologic Outcomes of Short-Course and Long-Course Radiotherapy for Locally Advanced Rectal Cancers Treated With Total Neoadjuvant Therapy.

INTRODUCTION: Total neoadjuvant therapy (TNT) for patients with locally advanced rectal cancer (LARC) is now the standard of care. Randomized trials suggest the use of short-course radiotherapy (SCRT) and long-course radiotherapy (LCRT) are oncologically equivalent. OBJECTIVE: To describe pathologic outcomes after surgical resections of patients receiving SCRT versus LCRT as part of TNT for LARC. PARTICIPANTS: All patients with LARC treated at a single tertiary hospital who underwent proctectomy after completing TNT were included. Patients were excluded if adequate details of TNT were not available in the electronic medical record. RESULTS: A total of 53 patients with LARC were included. Thirty-nine patients (73.5%) received LCRT and 14 (26.4%) received SCRT. Forty-nine patients (92.5%) were clinical stage III (cN1-2) prior to treatment. The average lymph node yield after proctectomy was 20.9 for SCRT and 17.0 for LCRT (P = .075). Of the 49 patients with clinically positive nodes before treatment, 76.9% of those who received SCRT and 72.2% of those who received LCRT achieved pN0 disease after TNT. Additionally, there were no significant differences in rates of pathologic complete response between patients who received SCRT and LCRT, 7.1% and 12.8%, respectively (P = .565). CONCLUSION: Pathologic outcomes of patients with LARC treated with SCRT or LCRT, as part of TNT, may be similar. Further prospective trials are needed to assess long-term clinical outcomes and to determine best treatment protocols.

Rectal Cancer Survival for Residual Carcinoma In Situ Versus Pathologic Complete Response After Neoadjuvant Therapy.

BACKGROUND: Pathologic complete response after neoadjuvant chemoradiotherapy for rectal cancer is associated with improved survival. It is unclear whether residual carcinoma in situ portends a similar outcome. OBJECTIVE: To compare the survival of patients with locally advanced rectal cancer who received neoadjuvant therapy and achieved pathologic carcinoma in situ versus pathologic complete response. DESIGN: Retrospective cohort study. SETTING: National public database. PATIENTS: A total of 4594 patients in the National Cancer Database from 2006 to 2016 with locally advanced rectal cancer who received neoadjuvant therapy, underwent surgery, and had node-negative ypTis or ypT0 on final pathology were included. Of these, 4321 patients (94.1%) had ypT0 and 273 (5.9%) had ypTis on final pathology. MAIN OUTCOME MEASURE: Overall survival. RESULTS: The median age was 60 years, and 1822 patients (39.7%) were women. On initial staging, 54.5% (n = 2503) had stage II disease and 45.5% (n = 2091) had stage III disease. The ypTis group had decreased overall survival compared to the ypT0 group (HR 1.42; 95% CI, 1.04-1.95; p = 0.028). Other factors associated with decreased overall survival were older age at diagnosis, increasing Charlson-Deyo score, and poorly differentiated tumor grade. Variables associated with improved survival were female sex, private insurance, and receipt of both neoadjuvant and adjuvant chemotherapy. For the total cohort, there was no difference in survival between clinical stage II and stage III. LIMITATIONS: Standard therapy versus total neoadjuvant therapy could not be abstracted. Overall survival was defined as the time from surgery to death from any cause or last contact, allowing for some erroneously misclassified deaths. CONCLUSIONS: ypTis is associated with worse overall survival than ypT0 for patients with locally advanced rectal cancer who receive neoadjuvant chemoradiotherapy followed by surgery. For this cohort, clinical stage was not a significant predictor of survival. Prospective trials comparing survival for these pathologic outcomes are needed. See Video Abstract .

Complete mesocolic excision and extended lymphadenectomy: Where should we stand?

Debate regarding the risks and merits of complete mesocolic excision and extended lymphadenectomy is ongoing, particularly for right-sided colon cancers. In this article, we hope to provide a succinct yet encompassing review of the relevant literature. We posit that complete mesocolic excision with D3 dissection is indicated in select patients with colon cancers, particularly those distal to the cecum.

Optimizing Appropriate Disposal of Unused Postoperative Opioid: What Happens to Unused Medication?

BACKGROUND: Increase in opioid prescribing practices has occurred with concurrent increases in the levels of abuse, addiction, and diversion of opioid pain medication. With 82.5 opioid prescriptions prescribed for every 100 U.S. citizens, the need for more effective strategies aimed at improving opioid disposal exist. Our study sought to examine the planned rates of appropriate opioid disposal after introduction of an activated charcoal home drug disposal system (Deterra®) in combination with formalized opioid disposal education. METHODS: Participants were recruited from an academic, public safety-net hospital and grouped into 3 cohorts, no formalized opioid disposal education (No Education), written and verbal patient education on appropriate opioid disposal (Education), and Deterra® in addition to formalized opioid disposal education (Deterra). Outcomes included patients reporting unacceptable methods of opioid disposal, storage of unused opiates, and patient satisfaction with disposal instructions. RESULTS: Reported unacceptable opioid disposal decreased from 80.6% (n = 87) in the no education group to 20% (n = 10) in the education group to 6% (n = 3) in the Deterra group (P < .001). Education decreased long-term storage of opioid medication after completion of usage from 42% (n = 36) to 2% (n = 1), P < .001. Between the education and Deterra groups, more patients felt that the disposal instructions were clear (94% (n = 47) vs 73% (n = 36), P = .006) and more followed acceptable disposal instructions (80% (n = 39) vs 94% (n = 47) P < .001). CONCLUSION: Deterra® along with formal opioid disposal education increases patients reporting plans for compliance with appropriate opioid disposal.

Assessing the Association Between Endoscopic Tattooing and Lymph Node Yield in Rectal Cancer.

INTRODUCTION: Preoperative endoscopic tattooing is an effective tool for intraoperative tumor localization in colon cancer. Endoscopic tattooing in rectal cancer may have unidentified benefits on lymph node yield, making it easier for pathologists to identify nodes during histopathologic assessment. There remains concern that tattoo ink may alter anatomical planes, increasing surgical difficulty. METHODS: Retrospective chart reviews from 2016 to 2021 of n = 170 patients presenting with rectal cancer were divided into two groups: with (n = 79) and without (n = 91) endoscopic tattoos. Demographics, operative details, tumor characteristics, prior chemoradiation, and pathologic details were collected. Primary outcome was total lymph node yield. Secondary outcomes were rates of adequate (> 12) nodes, margin status, and operative variables including operative time. RESULTS: No differences between pathologic stage, tumor height, high inferior mesenteric artery ligation, operative times, conversion rate, or surgical approach (open versus minimally invasive) were noted between groups. Receipt of neoadjuvant chemoradiation was less frequent in the endoscopic tattooing group (53.2% versus 76.9%, P ≤ 0.001). Total node number and rate of adequate lymph node yield were higher with endoscopic tattooing (20.5 ± 7.6 versus 16.8 ± 6.6 lymph nodes and 100.0% versus 83.5% adequate lymph node harvest, both P ≤ 0.001). Rates of positive circumferential and distal margins and complete total mesorectal excision were also similar. Regression analysis identified endoscopic tattooing (Incidence Risk Ratio 1.17, 95% confidence interval 1.04-1.31) and operative time more than 300 min (Incidence Risk Ratio 0.88, 95% confidence interval 0.77-0.99) had significant effects on lymph node harvest. Removal of patients with inadequate lymph node yield resulted in similar rates of total and positive lymph nodes. CONCLUSIONS: Endoscopic rectal tattooing is associated with increased lymph node yield (including after neoadjuvant chemoradiotherapy) without sacrificing oncologic or perioperative outcomes, although this effect is inconsistent when only considering patients with an adequate lymph node yield.

Prevalence of and Risk Factors for Incidental Colonic Diverticulosis.

INTRODUCTION: The true prevalence and pathogenesis of diverticulosis is poorly understood. Risk factors for diverticulosis are presently unclear, with most clinicians attributing its development to years of chronic constipation. Previous studies have been limited by their failure to include young, ethnically diverse patient populations. METHODS: Patients who presented to the emergency department of our hospital from January-September 2019 and underwent abdominal computerized tomography (CT) scan for the evaluation of appendicitis were included. CT's were reviewed for the presence of diverticulosis. Risk factors for diverticulosis were determined for two age groups: >40 and ≤ 40. RESULTS: A total of 359 patients were included in the study. The median age was 38.57.1% were male. 81.6% were Hispanic. 43.5% had colonic diverticulosis on CT. 198 patients (55.1%) were ≤ age 40. The rate of diverticulosis in this group was 35.3% (n = 70). Those with diverticulosis were not significantly older (median age 29 versus 27, P = 0.061) but had a higher median body mass index (BMI) (28.4 versus 25.3, P = 0.003) compared to those without diverticulosis. On multivariate analysis, no characteristics were associated with the presence of diverticulosis for this group. Over age 40, 53.4% of patients (n = 86) had diverticulosis. Patients with diverticulosis were more likely to be Hispanic (95.3% versus 73.3%, P ≤ 0.001), less likely to be Asian (2.4% versus 16.0%, P = 0.004), had a higher median BMI (28.7 versus 25.5, P ≤ 0.001), and were more likely to use alcohol (30.2% versus 14.7%, P = 0.024) than those without diverticulosis. On multivariate analysis, characteristics associated with the presence of diverticulosis were BMI >30 (odds ratio OR 2.22, 95% confidence interval CI 1.03-4.80), Hispanic ethnicity (OR 10.05, 95% CI 1.74-58.26), and alcohol use (OR 3.44, 95% CI 1.26-9.39). CONCLUSIONS: There was a higher rate of asymptomatic diverticulosis in the <40 cohort than previously reported in the literature. Obesity, alcohol use, and Hispanic ethnicity were associated with the presence of diverticulosis in patients > age 40, but no risk factors for diverticulosis were identified for patients ≤ age 40, suggesting that diverticular pathogenesis may differ by age. Constipation was not a risk factor for diverticulosis in either age group. The data regarding the prevalence of diverticulosis in Hispanic patients is lacking and should be the focus of future inquiry.

Endoscopy Reports for Rectosigmoid Tumors: Frequently Missing Key Information Needed for Surgical Planning.

INTRODUCTION: Endoscopy reports by gastroenterologists describing rectosigmoid tumors often are missing crucial data for surgical planning, leading to high rates of repeat exams before surgical decision-making. We hypothesize that there will be significant deficiencies in the endoscopic reporting of rectosigmoid lesions leading to high rates of repeat endoscopic examination at our institution. METHODS: Retrospective review from January 2016 to November 2019 included 188 patients with rectosigmoid lesions referred for surgery with an outside endoscopy report. Three criteria were abstracted from these reports or included pictures: (1) distance from the tumor to an anatomical landmark (anal verge, dentate line, sphincter), (2) Tattoo placement (if performed) and location, and (3) tumor relationship to the valves of Houston. Reports were classified exemplary, nearly adequate, or inadequate if 3, 2, and ≤ 1 of these criteria were met, respectively. RESULTS: Distance was reported in 38.8% (n = 73) of reports, with the anal verge being the most commonly reported anatomical landmark (32.4%, n = 61 reports). Tattoo was placed in 34.6% (n = 65), though only 21.8% (n = 41) described the location of the tattoo relative to the tumor. Relationship to the valves of Houston was seen in 29.2% (n = 55) of reports. Only 5.3% (n = 10) of outside endoscopy reports were graded as exemplary, 20.2% (n = 38) nearly adequate, and the remaining 74.5% (n = 140) inadequate. A total of 87.5% (n = 165) of patients required repeat endoscopy with a significantly higher proportion from the inadequate group. CONCLUSIONS: Many referring endoscopy reports contain inadequate information for the surgical planning of rectosigmoid tumor resection. Efforts to improve documentation (particularly about distance and location within the rectum) must be undertaken.

"Unresectable" polyp management utilizing advanced endoscopic techniques results in high rate of colon preservation.

PURPOSE: "Endoscopically unresectable" benign polyps identified during screening colonoscopy are often referred for segmental colectomy. Application of advanced endoscopic techniques can increase endoscopic polyp resection, sparing patients the morbidity of colectomy. This retrospective case-control study aimed to evaluate the success of colon preserving resection of "endoscopically unresectable" benign polyps using advanced endoscopic techniques including endoscopic mucosal resection, endoscopic submucosal dissection, endoluminal surgical intervention, full-thickness laparo-endoscopic excision, and combined endo-laparoscopic resection. METHODS: A prospectively maintained institutional database identified 95 patients referred for "endoscopically unresectable" benign polyps from 2015 to 2018. Cases were compared to 190 propensity score matched controls from the same database undergoing elective laparoscopic colectomy for other reasons. Primary outcome was rate of complete endoscopic polyp removal. Secondary outcomes included length of stay, unplanned 30-day readmission and reoperation, 30-day mortality, and post-procedural complications. RESULTS: Advanced endoscopic techniques achieved complete polyp removal without colectomy in 66 patients (70%). Failure was most commonly associated with previously attempted endoscopic resection and occult malignancy. Compared with matched colectomy controls, endoscopic polyp resection resulted in significantly shorter hospital length of stay (1.13 ± 2.41 vs 3.89 ± 4.57 days; p < 0.001), lower unplanned 30-day readmission (1.1% vs 7.7%; p < 0.05), and fewer postoperative complications (4.2% vs 33.9%; p < 0.001). Unplanned 30-day reoperation (2.1% vs 4.4%; p = 0.34) and 30-day mortality (0% vs 0.6%; p = 0.75) trended lower. CONCLUSIONS: Endoscopic resection of complex polyps can be highly successful, and it is associated with favorable outcomes and decreased morbidity when compared with segmental colon resection. Attempting colon preservation using these techniques is warranted.

Do or doughnut: A systematic review and pooled analysis on the utility of pathological evaluation of the anastomotic doughnut in oncological colorectal operations.

AIM: End-to-end anastomosis staplers are frequently used in colorectal surgery, generating two anastomotic doughnuts. Whether pathological evaluation of the doughnut changes clinical practice remains unclear. We aim to identify any effects of pathological evaluation of anastomotic doughnuts after oncological colorectal surgery. METHOD: We performed a systematic literature search utilizing PubMed, Clinicaltrials.gov, Cochrane, Embase and Web of Science databases and selected studies on evaluation of the anastomotic doughnut after oncological colorectal surgery with stapled end-to-end anastomosis. Outcome measures included: involved distal margin on the oncological sample, histological involvement of the doughnut, clinical change in management from a positive doughnut and study recommendations. RESULTS: Of the 5761 studies identified, eight studies encompassing 1754 patients were evaluated. Most operations were for primary colon (37.5%) or rectal adenocarcinoma (37.5%). Incidence of distal margin involvement of the oncological sample was reported in three papers, with six positive cases (1.1%). Of the 1754 doughnut pairs evaluated, five were positive for neoplasia (0.29%), three for adenomas (0.18%) and one for metaplastic polyp (0.06%), none of which changed postoperative treatment. Four studies recommended abandoning routine histopathological evaluation of anastomotic doughnuts, while the remaining four recommended evaluation only under certain criteria, including gross distal margin <2 cm (one study), gross distal margin <3 cm (one study), tumours undetected on gross examination (one study), 'histologically aggressive cancers' or grossly involved distal margin (one study). CONCLUSION: Routine evaluation of anastomotic doughnuts should be reconsidered, as <1% are positive for neoplasia. Exceptions may include specific scenarios where histopathology is likely to be clinically useful.

Dissecting the Perioperative Care Bundle.

Enhanced recovery after surgery (ERAS) protocols are comprehensive perioperative care pathways designed to mitigate the physiologic stressors associated with surgery and, in turn, improve clinical outcomes and lead to health care cost savings. Although individual components may differ, ERAS protocols are typically organized as multimodal care "bundles" that, when followed closely and in their entirety, are meant to generate amplified cumulative benefits. This manuscript examines some of the critical components, describes some areas where the science is weak (but dogma may be strong), and provides some of the evidence or lack thereof behind components of a standard ERAS protocol.

Full-Thickness Laparoendoscopic Excision for Management of Complex Colon Polyps.

BACKGROUND: Benign colon polyps are increasingly being detected because of improved colonoscopic screening and early detection of masses on the adenoma-to-carcinoma pathway. Full-thickness laparoendoscopic excision is a colon-preserving technique for endoscopically unresectable polyps consisting of endoscopically guided nonanatomic wedge colectomy. OBJECTIVE: This study aimed to evaluate the safety and success of full-thickness laparoendoscopic excision compared to segmental colectomy for complex polyps not amenable to endoscopic resection. DESIGN: This is a retrospective case-control study. SETTINGS: This study was conducted at a tertiary academic center. PATIENTS: A prospectively maintained institutional database identified 22 patients with benign complex polyps managed with full-thickness laparoendoscopic excision from 2015 to 2020. These patients were compared with 22 propensity score-matched controls from the same database that underwent laparoscopic segmental colectomy. MAIN OUTCOME MEASURES: Primary outcome was inpatient length of stay. Secondary outcomes included operative details and postoperative morbidities. RESULTS: Full-thickness laparoendoscopic excision was successful in all patients. Patients had a median age of 64 years (41-85), and 82% were men. Final pathology revealed complete excision of benign lesions in 20 of 22 patients and adenocarcinoma in 2 of 22. For the adenocarcinomas, 1 patient underwent subsequent elective colectomy without complications, and 1 patient declined surgery. Propensity score matching was successful for age, sex, BMI, ASA score, colon location, and prior abdominal surgery. Compared with controls, cases had significantly shorter operative time (89.5 minutes (46-290) vs 122 minutes (85-200), p = 0.009), length of stay (1 day (0-17) vs 3 days (1-8), p < 0.001), and reduced blood loss (5 mL (2-15) vs 25 mL (10-150), p < 0.001). Thirty-day morbidity (9.1% vs 27.3%, p = 0.240) was not significantly different. An unplanned 30-day reoperation was performed in 1 patient for suspected small-bowel obstruction. There was 1 mortality due to decompensated cirrhosis in the treatment group. LIMITATIONS: This study was limited by its single-institution retrospective design. CONCLUSIONS: Full-thickness laparoendoscopic excision is safe and successful compared with corresponding segmental colectomy for complex polyps. Favorable postoperative outcomes, including decreased operative time, length of stay, and blood loss, make it a useful approach for managing complex polyps throughout the colon.

Clinical Characteristics and Outcomes of Colorectal Cancer in the ColoCare Study: Differences by Age of Onset.

Early-onset colorectal cancer has been on the rise in Western populations. Here, we compare patient characteristics between those with early- (<50 years) vs. late-onset (≥50 years) disease in a large multinational cohort of colorectal cancer patients (n = 2193). We calculated descriptive statistics and assessed associations of clinicodemographic factors with age of onset using mutually-adjusted logistic regression models. Patients were on average 60 years old, with BMI of 29 kg/m2, 52% colon cancers, 21% early-onset, and presented with stage II or III (60%) disease. Early-onset patients presented with more advanced disease (stages III-IV: 63% vs. 51%, respectively), and received more neo and adjuvant treatment compared to late-onset patients, after controlling for stage (odds ratio (OR) (95% confidence interval (CI)) = 2.30 (1.82-3.83) and 2.00 (1.43-2.81), respectively). Early-onset rectal cancer patients across all stages more commonly received neoadjuvant treatment, even when not indicated as the standard of care, e.g., during stage I disease. The odds of early-onset disease were higher among never smokers and lower among overweight patients (1.55 (1.21-1.98) and 0.56 (0.41-0.76), respectively). Patients with early-onset colorectal cancer were more likely to be diagnosed with advanced stage disease, to have received systemic treatments regardless of stage at diagnosis, and were less likely to be ever smokers or overweight.

Reduction of Opioid Overprescribing and Use Following Standardized Educational Intervention: A Survey of Patient Experiences Following Anorectal Procedures.

BACKGROUND: A pilot study conducted at our institution showed that a significant amount of prescribed postoperative opioids is left unused with the potential for diversion and misuse. OBJECTIVE: This study aimed to evaluate the impact of provider- and patient-targeted educational interventions on postoperative opioid prescription and use following anorectal procedures. DESIGN: Patients were enrolled on July 2019 through March 2020 after implementing educational interventions (study) and were compared with the pilot study group (control) enrolled on August 2018 through May 2019. A telephone survey was conducted 1 week postoperatively. SETTINGS: This study was conducted at a 600-bed, safety-net hospital in southern California. PATIENTS: Adult patients undergoing ambulatory anorectal procedures were included. Patients who had undergone an examination under anesthesia, had been incarcerated, and had used opioids preoperatively were excluded. INTERVENTIONS: Educational interventions were developed based on the pilot study results. Providers received education on recommended opioid prescription quantities and a multimodal pain regimen. Standardized patient education infographics were distributed to patients pre- and postoperatively. MAIN OUTCOME MEASURES: The primary outcomes measured were total opioid prescribed, total opioid consumed, pain control satisfaction levels, and the need for additional opioid prescription. RESULTS: A total of 104 of 122 (85%) patients enrolled responded to the survey and were compared with the 112 patients included in the control group. Despite similar demographics, the study cohort was prescribed fewer milligram morphine equivalents (78.8 ± 11.3 vs 294.0 ± 33.1, p < 0.001), consumed fewer milligram morphine equivalents (23.0 ± 28.0 vs 57.1 ± 45.8, p < 0.001), and had a higher rate of nonopioid medication use (72% vs 10%, p < 0.001). The 2 groups had similar pain control satisfaction levels (4.1 ± 1.3 vs 3.9 ± 1.1 out of 5, p = 0.12) and an additional opioid prescription requirement (5% vs 4%, p = 1.0). LIMITATIONS: This study was limited by its single-center experience with specific patient population characteristics. CONCLUSION: Educational interventions emphasizing evidence-based recommended opioid prescription quantities and regimented multimodal pain regimens are effective in decreasing excessive opioid prescribing and use without compromising satisfactory pain control in patients undergoing ambulatory anorectal procedures.

Se distribuyeron infografías estandarizadas de educación para el paciente antes y después de la operación.PRINCIPALES MEDIDAS DE RESULTADO:Opioide total prescrito, opioide total consumido, niveles de satisfacción del control del dolor y necesidad de prescripción adicional de opioides.RESULTADOS:Un total de 104 de 122 (85%) pacientes inscritos respondieron a la encuesta y se compararon con los 112 pacientes incluidos en el grupo de control. A pesar de una demografía similar, a la cohorte del estudio se le prescribió menos miligramos de equivalente de morfina (MME) (78,8 ± 11,3 frente a 294,0 ± 33,1, p <0,001), consumió menos MME (23,0 ± 28,0 frente a 57,1 ± 45,8, p <0,001) y presentaron una mayor tasa de uso de medicamentos no opioides (72% vs 10%, p <0,001). Los dos grupos tenían niveles similares de satisfacción del control del dolor (4,1 ± 1,3 frente a 3,9 ± 1,1 de 5, p = 0,12) y la necesidad de prescripción de opioides adicionales (5% frente a 4%, p = 1,0).LIMITACIONES:Experiencia en un solo centro con características específicas de la población de pacientes.CONCLUSIÓN:Las intervenciones educativas que enfatizan las cantidades recomendadas de prescripción de opioides basadas en la evidencia y los regímenes de dolor multimodales reglamentados son efectivas para disminuir la prescripción y el uso excesivos de opioides sin comprometer el control satisfactorio del dolor en pacientes sometidos a procedimientos anorrectales ambulatorios.

The assessment of sarcopenia using psoas muscle thickness per height is not predictive of post-operative complications in IBD.

BACKGROUND: Sarcopenia is associated with postoperative complications in inflammatory bowel disease. It has most commonly been defined using the skeletal muscle index, computed after analysis of cross-sectional muscle area at L3. Psoas muscle thickness normalized to height (PMTH), which is easier to derive, is a potential surrogate of SMI and sarcopenia in patients with cirrhosis and chronic pancreatitis. We investigate whether sarcopenia defined by PMTH has utility in predicting post-operative outcomes in patients with inflammatory bowel disease. METHODS: We performed a retrospective study of adults undergoing IBD-related surgery from 2009 to 2019 at two hospitals. Sarcopenia was defined by sex-specific PMTH at the umbilicus on cross-sectional imaging using a 50th percentile median cutoff. Predictive models were created using variables (BMI, age, sex, smoking status, albumin, INR, platelets, hemoglobin, hypertension, diabetes, CAD, medications) that may be associated with complications (mortality, reoperation, readmission, transfusions, ICU admission, infection, DVT/PE), and sarcopenia for comparison. RESULTS: 85 patients with IBD were included. Lower albumin level (OR = 0.52, p = 0.039) and biologic use (OR = 5.92, p = 0.006) were associated with postoperative complications. There was no significant difference using PMTH compared to a model incorporating hypoalbuminemia and biologic use in predicting complications. Sarcopenia on univariate analysis was associated with a lower 30 day rate of reoperation (p = 0.04). CONCLUSIONS: A low status of PMTH was not associated with increased postoperative complications, however hypoalbuminemia and biologic use were. PMTH as a surrogate for sarcopenia requires further study, ideally with prospective studies comparing PMTH with accepted radiographic surrogates for sarcopenia, to determine its role in clinical decision making.

LigaSure™ haemorrhoidectomy and the risk of postoperative bleeding.

AIM: LigaSure™ is an electro-surgical device that has increasingly been utilized in haemorrhoid surgery. However, recent literature has highlighted a possible increased risk of delayed postoperative bleeding following LigaSure haemorrhoidectomy (LH). We aim to evaluate the rates of postoperative bleeding following LigaSure compared to Ferguson (closed) haemorrhoidectomy (FH). METHODS: A retrospective cohort study was undertaken at our single academic safety-net county hospital from August 2016 through July 2019 evaluating patients who received FH or LH. Patient demographics, surgical data, postoperative emergency department visit for pain or bleeding within 30 days and resulting transfusion requirement, and rates of readmission and interventions within 30 days were collected. RESULTS: Sixty-one FH and 66 LH patients were identified. The groups had no difference in demographics. The LH group and FH group had similar rates of postoperative emergency department visits (29% vs. 23%, P = 0.454), as well as visits for bleeding (20% vs. 11%, P = 0.204). The average operating time was also significantly shorter with LH (14.5 min vs. 24.9 min, P ≤ 0.001). On multivariate analysis, male sex (OR 7.28, 95% CI 1.88-28.25) and haemorrhoid grade ≤2 (OR 4.64, 95% CI 1.31-16.49) were significantly associated with postoperative bleeding on multivariate analysis. Use of LH was not independently associated with postoperative bleeding risk (OR 1.89, 95% CI 0.70-5.11). CONCLUSIONS: LH and FH have similar risks for postoperative bleeding and other complications. Male sex and haemorrhoid Grades 1 or 2 may be associated with increased postoperative bleeding risk. Excisional haemorrhoidectomy should be undertaken with caution for male patients with lower internal haemorrhoid grades.

Characteristics of Early-Onset vs Late-Onset Colorectal Cancer: A Review.

Importance: The incidence of early-onset colorectal cancer (younger than 50 years) is rising globally, the reasons for which are unclear. It appears to represent a unique disease process with different clinical, pathological, and molecular characteristics compared with late-onset colorectal cancer. Data on oncological outcomes are limited, and sensitivity to conventional neoadjuvant and adjuvant therapy regimens appear to be unknown. The purpose of this review is to summarize the available literature on early-onset colorectal cancer. Observations: Within the next decade, it is estimated that 1 in 10 colon cancers and 1 in 4 rectal cancers will be diagnosed in adults younger than 50 years. Potential risk factors include a Westernized diet, obesity, antibiotic usage, and alterations in the gut microbiome. Although genetic predisposition plays a role, most cases are sporadic. The full spectrum of germline and somatic sequence variations implicated remains unknown. Younger patients typically present with descending colonic or rectal cancer, advanced disease stage, and unfavorable histopathological features. Despite being more likely to receive neoadjuvant and adjuvant therapy, patients with early-onset disease demonstrate comparable oncological outcomes with their older counterparts. Conclusions and Relevance: The clinicopathological features, underlying molecular profiles, and drivers of early-onset colorectal cancer differ from those of late-onset disease. Standardized, age-specific preventive, screening, diagnostic, and therapeutic strategies are required to optimize outcomes.

COVID-19 Impact on Colorectal Daily Practice-How Long Will It Take to Catch Up?

BACKGROUND: All elective surgeries have been postponed at our institution starting 3/16/20 due to the COVID-19 pandemic. We assessed changes in hospital resource utilization and estimated the future backlog of cases in the colorectal surgery division of a large safety-net hospital. METHODS: Patients undergoing colorectal procedures from 3/16/20 to 4/23/20 (COVID) were compared with those from January through June 2018 (historical). Resource utilization rates were calculated by weekly case volumes and hospital stay in each group. A future catch up timeframe and new wait times from scheduling to surgery dates were calculated. RESULTS: The COVID and historical groups included 13 and 239 patients, respectively. The COVID group showed a 74% relative decrease in weekly surgical case rates (9.2 to 2.4 patients per week). Both groups had similar lengths of stay. The COVID group had a longer average ICU stay (1.4 ± 2.5 days vs. 0.4 ± 1.2 days, P = 0.016) and a 132% increase in ICU resource utilization. Overall, the COVID group had a 48% relative decrease in hospital resource utilization, owing to reduced volume but higher acuity. If the surgery numbers returns to pre-COVID volumes, the calculated "catch up" times range from 4.6 weeks to 9.2 weeks. Wait times for new cases may increase by 70% compared with pre-COVID levels. CONCLUSION: Cancelling elective colorectal surgeries results in a decrease in overall but increase in ICU-specific resource utilization. Though necessary, cancellations result in an increasing backlog of cases that poses significant future logistical and clinical challenges in an already overburdened safety-net hospital. Effective triage systems will be critical to prioritize this backlog.
