“…As the incidence of diverticular disease increases [ 45 , 46 ] emergent colectomies are becoming more frequent [ 6 , 47 ]. Emergency colorectal surgery and diverticular disease are known independent risk factors for VTE [ 9 , 48 ]. Despite this rising prevalence, post-colectomy VTE rates for diverticular disease in particular have not been previously explored.…”
Aim
This study reports venous thromboembolism (VTE) rates following colectomy for diverticular disease to explore the magnitude of postoperative VTE risk in this population and identify high risk subgroups of interest.
Method
English national cohort study of colectomy patients between 2000 and 2019 using linked primary (Clinical Practice Research Datalink) and secondary (Hospital Episode Statistics) care data. Stratified by admission type, absolute incidence rates (IR) per 1000 person-years and adjusted incidence rate ratios (aIRR) were calculated for 30- and 90-day post-colectomy VTE.
Results
Of 24,394 patients who underwent colectomy for diverticular disease, over half (57.39%) were emergency procedures with the highest VTE rate seen in patients ≥70-years-old (IR 142.27 per 1000 person-years, 95%CI 118.32–171.08) at 30 days post colectomy. Emergency resections (IR 135.18 per 1000 person-years, 95%CI 115.72–157.91) had double the risk (aIRR 2.07, 95%CI 1.47–2.90) of developing a VTE at 30 days following colectomy compared to elective resections (IR 51.14 per 1000 person-years, 95%CI 38.30–68.27). Minimally invasive surgery (MIS) was shown to be associated with a 64% reduction in VTE risk (aIRR 0.36 95%CI 0.20–0.65) compared to open colectomies at 30 days post-op. At 90 days following emergency resections, VTE risks remained raised compared to elective colectomies.
Conclusion
Following emergency colectomy for diverticular disease, the VTE risk is approximately double compared to elective resections at 30 days while MIS was found to be associated with a reduced risk of VTE. This suggests advancements in postoperative VTE prevention in diverticular disease patients should focus on those undergoing emergency colectomies.

“…Patients with both uncomplicated diverticulitis and perforated complicated diverticulitis have a 40% increased risk of developing venous thrombosis. 1 While there are reports of diverticulitis associated with gonadal vein thrombosis, 2 there is no literature to date on postoperative development of gonadal vein thrombus extending into the renal vein after sigmoid colectomy. Our case report details a patient with no significant risk factors who developed left gonadal vein thrombosis extending into the left renal vein after colectomy.…”
Post operative pain is often the cause of many ED visits. When patients are discharged and return with postoperative abdominal pain, common etiologies include incisional pain, neuropathic pain, musculoskeletal pain from immobility, ileus, and more sinister causes including adhesive bowel obstruction, abscess formation, and anastomotic leak. We present a 62 year-old female without any hereditary thrombophilia or other prothrombotic factors who presented to the ED after a sigmoid colectomy and diverting ileostomy for perforated diverticulitis and subsequent ileostomy reversal with abdominal pain. CT discovered a left ovarian vein thrombus extending into the left renal vein. With a myriad of diagnoses, it is important to have a low threshold for imaging to rule out serious pathology and also diagnose any unusual causes that can be treated promptly to prevent organ damage and subsequent complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
