Preoperative Opioid Prescription Is Associated With Major Complications in Patients With Crohn's Disease Undergoing Elective Ileocolic Resection.

BACKGROUND: Opioid use has grown exponentially over the last decade. The effect of preoperative opioid prescription in patients with Crohn's disease undergoing surgery is unknown. OBJECTIVE: The purpose of this study was to identify whether preoperative opioid prescription is associated with adverse postoperative outcomes in Crohn's disease. DESIGN: This is a single-institution retrospective observational study. SETTINGS: This study was performed at an academic tertiary care center. Details of preoperative opioid prescription were collected from the Kentucky All-Schedule Prescription Electronic Reporting database and the electronic databases of bordering states. PATIENTS: Consecutive patients undergoing ileocolic resection for Crohn's disease from 2014 to 2018 were included. MAIN OUTCOME MEASURES: The outcomes examined were major complications (Clavien-Dindo ≥3a), length of stay, and 30-day hospital readmission. RESULTS: Fifty one of 118 patients were prescribed opioids within 6 months preoperatively (range, 0-33,760 morphine milligram equivalents). Patients with preoperative opioid prescription compared with no preoperative opioid prescription required more daily opioids during hospital admission (p = 0.024). Nineteen patients had a major postoperative complication (preoperative opioid prescription: 26% (13/51) vs no preoperative opioid prescription: 9% (6/67)). On multivariable analysis, preoperative opioid prescription (OR = 2.994 (95% CI, 1.024-8.751); p = 0.045) was a significant risk factor for a major complication. Preoperative opioid prescription was associated with increased length of stay (p < 0.001) and was a risk factor for readmission (OR = 2.978 (95% CI, 1.075-8.246); p = 0.036). Twenty-four patients were readmitted. Using a cutoff for higher opioid prescription of 300 morphine milligram equivalents within 6 months preoperation (eg, 60 tablets of hydrocodone/acetaminophen 5/325), preoperative opioid prescription remained a risk factor for major postoperative complications (OR = 3.148 (95% CI, 1.110-8.928); p = 0.031). LIMITATIONS: This was a retrospective study and could not assess nonprescribed opioid use. CONCLUSIONS: Preoperative opioid prescription was a significant risk factor for adverse outcomes in patients with Crohn's disease undergoing elective ileocolic resection.

Los pacientes con prescripción preoperatoria de opioides en comparación con ninguna prescripción preoperatoria de opioides requirieron más opioides diarios durante el ingreso hospitalario (p = 0,024). Diecinueve pacientes tuvieron una complicación postoperatoria importante (prescripción preoperatoria de opioides: 26% [13/51] frente a ninguna prescripción preoperatoria de opioides: 9% [6/67]). En el análisis multivariable, la prescripción de opioides preoperatorios (OR = 2.994, IC 95%: 1.024-8.751, p = 0.045) fueron factores de riesgo significativos para una complicación mayor. La prescripción preoperatoria de opioides se asoció con un aumento de la duración de la estadía (p <0.001) y fue un factor de riesgo para el reingreso (OR = 2.978, IC 95%: 1.075-8.246, p = 0.036). Veinticuatro pacientes fueron readmitidos. Utilizando un límite para una mayor prescripción de opioides de 300 miligramos equivalentes de morfina dentro de los 6 meses previos a la operación (p. Ej., 60 tabletas de hidrocodona / acetaminofén 5/325), la prescripción preoperatoria de opioides siguió siendo un factor de riesgo para complicaciones postoperatorias mayores (OR = 3.148 IC 95%: 1.110-8.928, p = 0.031).Este fue un estudio retrospectivo y no pudo evaluar el uso de opioides no prescritos.La prescripción preoperatoria de opioides fue un factor de riesgo significativo para los resultados adversos en pacientes con enfermedad de Crohn sometidos a resección ileocólica electiva.

The difficulty with localization of rectal cancer after neoadjuvant chemoradiation therapy.

Neoadjuvant chemoradiation therapy (NCRT) has become the standard treatment for locally advanced rectal cancer. Subsequent downstaging can make identification of the primary tumor challenging. Complete pathologic response rates of 8 per cent to 27 per cent are seen with current NCRT regimen. Two patients were referred to our institution after NCRT and subsequent low anterior resection in whom no residual cancer was found in the resected specimen but who manifested cancer in the distal rectum in the early postoperative period. Resection of a locally advanced rectal cancer after NCRT associated with significant tumor shrinkage is facilitated by the surgeon's evaluation with proctoscopy and tumor tattooing before the initiation of NCRT. After NCRT, preoperative proctoscopy, distal rectal evaluation after a sphincter sparing procedure in the operating room, and thorough specimen evaluation help to insure that the surgeon has removed the rectal cancer with an appropriate margin. These cases emphasize how important it is for the surgeon to be involved in the staging phase of managing the patient with rectal cancer.

Current management of diverticulitis.

Diverticulitis is classified as uncomplicated or complicated, i.e., associated with perforation, fistula, or obstruction. CT allows more reliable characterization of an acute attack of diverticulitis. Medical management is reserved for uncomplicated diverticulitis and the initial phase of treatment of diverticulitis associated with abscess formation. Percutaneous abscess drainage is a major advance, which permits one-stage resection in a majority of cases. Diverticulitis associated with free perforation can be selectively managed with resection and primary anastomosis, although a Hartmann resection is likely to be performed. A fistula associated with diverticulitis can usually be managed with a one-stage resection. Obstruction can be managed selectively with resection with on-table bowel preparation, primary anastomosis, and proximal diversion. Laparoscopic techniques permit successful performance of elective resections most of the time. Hand assistance is of particular value when the patient has dense fibrosis.

Multiquadrant robotic colorectal surgery: the da Vinci Xi vs Si comparison.

The newly introduced da Vinci Xi Surgical System hopes to address the shortcomings of its predecessor, specifically robotic arm restrictions and difficulty working in multiple quadrants. We compare the two robot platforms in multiquadrant surgery at a major colorectal referral center. Forty-four patients in the da Vinci Si group and 26 patients in the Xi group underwent sigmoidectomy or low anterior resection between 2014 and 2016. Patient demographics, operative variables, and postoperative outcomes were compared using descriptive statistics. Both groups were similar in age, sex, BMI, pelvic surgeries, and ASA class. Splenic flexure was mobilized in more (p = 0.045) da Vinci Xi cases compared to da Vinci Si both for sigmoidectomy (50 vs 15.4%) and low anterior resection (60 vs 29%). There was no significant difference in operative time (219.9 vs 224.7 min; p = 0.640), blood loss (170.0 vs 188.1 mL; p = 0.289), length of stay (5.7 vs 6 days; p = 0.851), or overall complications (26.9 vs 22.7%; p = 0.692) between the da Vinci Xi and Si groups, respectively. Single-dock multiquadrant robotic surgery, measured by splenic flexure mobilization with concomitant pelvic dissection, was more frequently performed using the da Vinci Xi platform with no increase in operative time, bleeding, or postoperative complications. The new platform provides surgeons an easier alternative to the da Vinci Si dual docking or combined robotic/laparoscopic multiquadrant surgery.

The use of tissue flaps as an adjunct to pelvic surgery.

BACKGROUND: The clinical problems of advanced malignancy with invasion of cancers into adjacent organs or structures, fistulizing complications from radiation therapy, postoperative infections, and delayed postoperative healing continue to challenge pelvic surgeons, regardless of subspecialty. The use of autologous muscle and myocutaneous flaps has been applied to the management and prevention of these clinical problems and found to be most helpful. METHODS: Records of patients undergoing abdominopelvic procedures in a single unit during the 15-year period from 1990 to 2005 were reviewed, and patients undergoing autologous tissue flaps were reviewed with respect to indications, complications, and outcomes. RESULTS: Thirty-four patients underwent 35 autologous muscle or myocutaneous flaps for the following indications: large anticipated defects in primary or reoperative cancer surgery (13 patients); malignant, traumatic, inflammatory, or radiation-induced fistulae (12 patients); excision of (an) adjacent organ(s) with need for reconstruction (7 patients); and chronic nonhealing pelvic wounds (2 patients). Wound complications occurred in 41% of patients; however, primary healing of flaps occurred in 88% of patients. CONCLUSIONS: The use of autologous tissue flaps in select patients can be a useful adjunct in pelvic surgery in dealing with a wide variety of problems, specifically in filling large defects, providing vascularized tissue for fistula closure, and avoiding delayed wound healing commonly seen after high-dose radiation.

Changes in 16s RNA Gene Microbial Community Profiling by Concentration of Prokaryotic DNA.

Microbial metagenomics are hindered in clinical tissue samples as a result of the large relative amount of human DNA in relation to microbial DNA acting as competitive inhibitors of downstream applications. We evaluated the LOOXSTER® Enrichment Kit to separate eukaryotic and prokaryotic DNA in submucosal intestinal tissue samples having a low microbial biomass and to determine the effects of enrichment on 16s rRNA microbiota sequencing. The enrichment kit reduced the amount of human DNA in the samples 40-70% resulting in a 3.5-fold increase in the number of 16s bacterial gene sequences detected on the Illumina MiSeq platform. This increase was accompanied by the detection of 41 additional bacterial genera and 94 tentative species. The additional bacterial taxa detected accounted for as much as 25% of the total bacterial population that significantly altered the relative prevalence and composition of the intestinal microbiota. The ability to reduce the competitive inhibition created by human DNA and the concentration of bacterial DNA may allow metagenomics to be performed on complex tissues containing a low bacterial biomass.

Mortality after elective colon resection: the search for outcomes that define quality in surgical practice.

BACKGROUND: Process measures constitute the focal point of surgical quality studies. High levels of compliance with such processes have not correlated with improved outcomes. Wide ranges of reported hospital death rates led us to hypothesize that survival after elective colon resection would be a legitimate outcomes measure for quality of surgical practice. STUDY DESIGN: We studied risk-adjusted hospital mortality rates of 85,260 patients in teaching hospitals as reported to the University HealthSystem Consortium (UHC) January 1, 2005 to March 31, 2011. Data were analyzed by institution and surgeon (deidentified). There were 34,504 patients from the HealthCare Utilization Project (HCUP, 2007-2008), who provided a comparison group for nonteaching hospitals. Surgeons with less than 1 year of reported data were excluded. RESULTS: Elective colon resection mortality rates were densely concentrated around 1.56% for teaching hospitals and at 1.08% for defined surgeons. HCUP data demonstrated a 1.38% nonteaching hospital mortality rate. Neither hospital nor surgeon volume were determinants of mortality, and lower volume entities displayed the widest mortality variations. Among 193 teaching hospitals, there were 6 outliers (4.1%), defined as >2 standard deviations (SDs) above the mean. Similarly, 32 of 681 individual surgeons (4.7%) had a risk-adjusted hospital mortality rate >2SDs above the mean. CONCLUSIONS: Elective colon resection is a safe procedure in both teaching hospitals and nonteaching hospitals, with an impressively homogenous mean mortality rate of 1.56% in teaching hospitals, and 1.38% in nonteaching hospitals. We reject our original hypothesis because the data do not sufficiently discriminate to permit the use of death after elective colon resection as a differentiating quality measure; however, the data do identify individual poor performers. Poor performing institutions/surgeons should seek extramural guidance to improve their outcomes or discontinue performing such operations.
