Item A comparison of open or laparoscopic colectomy outcomes for the management of ischemic colitis using the ACS-NSQIP database(Elsevier, 2023-06-03) Duggan, Ben S.; Becker, Tim; DeLeon, Genaro A.; Rao, Varun; Pei, Kevin Y.; Medicine, School of MedicineIntroduction: Ischemic colitis is a common manifestation of intestinal ischemia and is potentially a surgical emergency. Although such surgical emergencies were historically approached via open exploration, it is uncertain if there is a role for minimally invasive techniques. This study compares open vs laparoscopic colectomy techniques in the management of ischemic colitis. Methods: Using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database, patients with ischemic colitis undergoing colectomy from 2005 to 2019 were compared. The primary outcome of interest was 30-day mortality. Additional outcomes of interest were procedure related readmission, procedure related reoperation, length of stay, surgical site infections (SSI), septic shock, and other complications. Outcomes of interest were compared using multivariate logistic regression. Results: 7,928 patients had ischemic colitis with 7,209 undergoing open colectomy and 719 undergoing laparoscopic colectomy. The mortality rate was significantly lower using a laparoscopic approach compared to open (6.4% vs 26%, p=<0.001) and associated with a lower odd of mortality (OR 0.58; 95% CI [0.35, 0.95]). Procedure related reoperation was lower in the laparoscopic group (6.5% vs 11%, p<0.001), but multivariate analysis was not significant (OR 0.65; 95% CI [0.43,1]). Readmission rates were not statistically different (12% vs 10%, p = 0.2). Postoperative length of stay (7 vs 12 days, p=<0.001), septic shock (6.7% vs 27%, p=<0.001), and organ space SSI (3.2% vs 6.9%, p=<0.001) were significantly decreased using a laparoscopic approach. Discussion: 30-day postoperative mortality was significantly lower using a laparoscopic. Patients that had a laparoscopic colectomy had shorter hospital stays. While patients that underwent laparoscopic procedures tended to be less sick, multivariate analysis showed decreased rates of sepsis and surgical site infections compared to open colectomies when correcting for these factors. Conclusion: Laparoscopic colectomy may be a better surgical approach for patients with ischemic colitis compared to open colectomy.Item A postdischarge venous thromboembolism risk calculator for inflammatory bowel disease surgery(Elsevier, 2021) Schlick, Cary Jo R.; Yuce, Tarik K.; Yang, Anthony D.; McGee, Michael F.; Bentrem, David J.; Bilimoria, Karl Y.; Merkow, Ryan P.; Surgery, School of MedicineBackground: Guidelines recommend extended chemoprophylaxis for venous thromboembolism in high-risk patients having operations for inflammatory bowel disease. Quantifying patients' risk of venous thromboembolism, however, remains challenging. We sought (1) to identify factors associated with postdischarge venous thromboembolism in patients undergoing colorectal resection for inflammatory bowel disease and (2) to develop a postdischarge venous thromboembolism risk calculator to guide prescribing of extended chemoprophylaxis. Methods: Patients who underwent an operation for inflammatory bowel disease from 2012 to 2018 were identified from the American College of Surgeons National Surgical Quality Improvement Program for colectomy and proctectomy procedure targeted modules. Postdischarge venous thromboembolism included pulmonary embolism or deep vein thrombosis diagnosed after discharge from the index hospitalization. Multivariable logistic regression estimated the association of patient/operative factors with postdischarge venous thromboembolism. A postdischarge venous thromboembolism risk calculator was subsequently constructed. Results: Of 18,990 patients, 199 (1.1%) developed a postdischarge venous thromboembolism within the first 30 postoperative days. Preoperative factors associated with postdischarge venous thromboembolism included body mass index (1.9% with body mass index ≥35 vs 0.8% with body mass index 18.5-24.9; odds ratio 2.34 [95% confidence interval 1.49-3.67]), steroid use (1.3% vs 0.7%; odds ratio 1.91 [95% confidence interval 1.37-2.66]), and ulcerative colitis (1.5% vs 0.8% with Crohn's disease; odds ratio 1.76 [95% confidence interval 1.32-2.34]). Minimally invasive surgery was associated with postdischarge venous thromboembolism (1.2% vs 0.9% with open; odds ratio 1.42 [95% confidence interval 1.05-1.92]), as was anastomotic leak (2.8% vs 1.0%; odds ratio 2.24 [95% confidence interval 1.31-3.83]) and ileus (2.1% vs 0.9%; odds ratio 2.60 [95% confidence interval 1.91-3.54]). The predicted probability of postdischarge venous thromboembolism ranged from 0.2% to 14.3% based on individual risk factors. Conclusion: Preoperative, intraoperative, and postoperative factors are associated with postdischarge venous thromboembolism after an operation for inflammatory bowel disease. A postdischarge venous thromboembolism risk calculator was developed which can be used to tailor extended venous thromboembolism chemoprophylaxis by individual risk.Item Association Between Missed Doses of Chemoprophylaxis and VTE Incidence in a Statewide Colectomy Cohort(Wolters Kluwer, 2021) Khorfan, Rhami; Kreutzer, Lindsey; Love, Remi; Schlick, Cary Jo R.; Chia, Matthew; Bilimoria, Karl Y.; Yang, Anthony D.; Surgery, School of MedicineItem Cold snare polypectomy effectively reduces polyp burden in familial adenomatous polyposis(Thieme Publishing Group, 2016-04) Patel, Nedhi J.; Ponugoti, Prasanna L.; Rex, Douglas K.; Department of Medicine, IU School of MedicineBACKGROUND AND STUDY AIMS: Familial adenomatous polyposis (FAP) is generally managed by colectomy, but in some cases surgery is delayed and polyp burdens are managed endoscopically. We aimed to describe the use of cold snare polypectomy to control the polyp burden in selected patients with FAP. PATIENTS AND METHODS: This was a retrospective cohort study. Polyps were counted and the range of polyp size recorded at each examination. Patients with a reduction in polyp number and mean size were considered to have successful endoscopic reduction of their polyp burdens. RESULTS: Of 79 patients with FAP, 21 had an attempt at delaying surgery by cold snaring of at least 30 adenomas, and had at least one follow-up at our institution. Ten patients had intact colons, 6 had intact rectums, and 5 had heavy polyp burdens in an ileo-anal pouch. Among the 21 patients, the mean number of polyps resected at the first examination was 85, range 30 - 342. Nineteen of 21 patients had fewer polyps at the second examination, and of those, only one had any persistence of adenomas ≥ 1 cm in size. During follow-up, two patients underwent surgical resection and the remainder had reductions in their polyp burdens at follow-up endoscopy. CONCLUSIONS: Cold snare polypectomy effectively reduces polyp burden in selected FAP patients.Item Compositional and Temporal Changes in the Gut Microbiome of Pediatric Ulcerative Colitis Patients Are Linked to Disease Course(Elsevier, 2018-10-10) Schirmer, Melanie; Denson, Lee; Vlamakis, Hera; Franzosa, Eric A.; Thomas, Sonia; Gotman, Nathan M.; Rufo, Paul; Baker, Susan S.; Sauer, Cary; Markowitz, James; Pfefferkorn, Marian; Oliva-Hemker, Maria; Rosh, Joel; Otley, Anthony; Boyle, Brendan; Mack, David; Baldassano, Robert; Keljo, David; LeLeiko, Neal; Heyman, Melvin; Griffiths, Anne; Patel, Ashish S.; Noe, Joshua; Kugathasan, Subra; Walters, Thomas; Huttenhower, Curtis; Hyams, Jeffrey; Xavier, Ramnik J.; Medicine, School of MedicineEvaluating progression risk and determining optimal therapy for ulcerative colitis (UC) is challenging as many patients exhibit incomplete responses to treatment. As part of the PROTECT (Predicting Response to Standardized Colitis Therapy) Study, we evaluated the role of the gut microbiome in disease course for 405 pediatric, new-onset, treatment-naive UC patients. Patients were monitored for 1 year upon treatment initiation, and microbial taxonomic composition was analyzed from fecal samples and rectal biopsies. Depletion of core gut microbes and expansion of bacteria typical of the oral cavity were associated with baseline disease severity. Remission and refractory disease were linked to species-specific temporal changes that may be implicative of therapy efficacy, and a pronounced increase in microbiome variability was observed prior to colectomy. Finally, microbial associations with disease-associated serological markers suggest host-microbial interactions in UC. These insights will help improve existing treatments and develop therapeutic approaches guiding optimal medical careItem Fecal Microbiota Transplantation(Thieme, 2023-01-25) Cheng, Yao-Wen; Fischer, Monika; Medicine, School of MedicineFecal microbiota transplantation (FMT) is the process of transplanting stool from a healthy donor into the gut of a patient for therapeutic purposes. Current guidelines recommend FMT for the prevention of multiply recurrent Clostridioides difficile infection (CDI) after two recurrences, with cure rates approaching 90%. Emerging evidence also supports the use of FMT in the management of severe and fulminant CDI, resulting in decreased mortality and colectomy rates compared with standard of care approach. FMT shows promise as salvage therapy for critically-ill, refractory CDI patients who are poor surgical candidates. FMT should be considered early in the clinical course of severe CDI, preferably within 48 hours of failing to respond to antibiotic therapy and volume resuscitation. Besides CDI, ulcerative colitis was more recently identified as a potential treatment target for FMT. Several live biotherapeutics for microbiome restoration are on the horizon.Item Fecal Microbiota Transplantation: Redefining Surgical Management of Refractory Clostridium difficile Infection(Thieme, 2020-03) Cheng, Yao-Wen; Fischer, Monika; Medicine, School of MedicineFecal microbiota transplantation (FMT) is the process of transplanting stool from a healthy donor into the gut of a diseased individual for therapeutic purposes. It has a clearly defined role in the treatment of recurrent Clostridium difficile (reclassified as “ Clostridioides difficile ”) infection (CDI), with cure rates over 90% and decreased rates of subsequent recurrence compared with anti-CDI antibiotics. There is emerging evidence that FMT is also effective in the treatment of severe and fulminant CDI, with associated decreases in mortality and colectomy rates compared with standard antibiotic therapy. FMT shows promise as salvage therapy for critically-ill CDI patients refractory to maximum medical therapy and not deemed to be surgical candidates. FMT should be considered early in the course of severe CDI and should be delivered immediately in patients with signs of refractory CDI. Expansion of FMT's use along the spectrum of CDI severity has potential to decrease associated rates of mortality and colectomy.Item Trousseau Syndrome in a 25-Year-Old Woman with Occult Colon Malignancy, Lynch Syndrome, and Chronic Thromboembolic Pulmonary Hypertension(Allen Press, 2022) Matthews, Caleb R.; Madison, Mackenzie; Zhang, Chen; Waters, Joshua; Garcia, Jose P.; Beckman, Daniel; Surgery, School of MedicineWe present a rare case of thrombosis associated with an occult colon malignancy (Trousseau syndrome) in a 25-year-old woman who also presented with previously unidentified Lynch syndrome and acute-on-chronic thromboembolic pulmonary hypertension. Staged treatment included bilateral pulmonary endarterectomy under deep hypothermic circulatory arrest, followed 11 days later by laparoscopic subtotal colectomy and creation of a primary anastomosis. The patient tolerated both procedures well and recovered normal functional status. Final pathologic analysis of the resected colon mass revealed a pT3N0, stage IIA adenocarcinoma; no adjuvant therapy was administered. At her one-year follow-up visit, the patient was cancer-free, remained on lifelong apixaban anticoagulation, and was undergoing routine monitoring and genetic counseling. This case highlights the need for multidisciplinary management of a patient with severe chronic thromboembolic pulmonary hypertension and a concomitant malignancy.
