Abstract
Diverticular disease is a common problem where patients with diverticulosis have a 1-4 per cent risk of acute diverticulitis. Current guidelines recommend a colonoscopy after.the resolution of acute diverticulitis. The aim of this study was to evaluate the yield of significant findings on colonoscopy after an episode of diverticulitis. This is a retrospective analysis of patients who underwent colonoscopy after an episode of diverticulitis between November 2005 and August 2017 at three major teaching hospitals. Advanced adenomas were defined as adenomas ≥1 cm, serrated adenomas, and tubulovillous or villous adenomas. A total of 584 patients (298 males; 51%) underwent colonoscopy for a history of diverticulitis after resolution of acute symptoms. Colonoscopy was complete in 488 patients (84%). Among these 488 patients, 446 had diverticular disease, 31 had advanced adenomas, and four had adenocarcinomas. Colonoscopies were incomplete in 96 patients (16%). Forty-six of those patients underwent surgery. The overall incidence of advanced adenomas and adenocarcinomas was 32 (5.4%) and nine (1.5%), respectively. In our study, the prevalence of advanced adenomas and adenocarcinomas was relatively high compared with the average risk individuals. Our findings support that patients after an episode of diverticulitis should continue to get a colonoscopy.

Evaluating the ACS-NSQIP Risk Calculator in Primary GI Neuroendocrine Tumor: Results from the United States Neuroendocrine Tumor Study Group.

Abstract
The ACS established an online risk calculator to help surgeons make patient-specific estimates of postoperative morbidity and mortality. Our objective was to assess the accuracy of the ACS-NSQIP calculator for estimating risk after curative intent resection for primary GI neuroendocrine tumors (GI-NETs). Adult patients with GI-NET who underwent complete resection from 2000 to 2017 were identified using a multi-institutional database, including data from eight academic medical centers. The ability of the NSQIP calculator to accurately predict a particular outcome was assessed using receiver operating characteristic curves and the area under the curve (AUC). Seven hundred three patients were identified who met inclusion criteria. The most commonly performed procedures were resection of the small intestine with anastomosis (N = 193, 26%) and partial colectomy with anastomosis (N = 136, 18%). The majority of patients were younger than 65 years (N = 482, 37%) and ASA Class III (N = 337, 48%). The most common comorbidities were diabetes (N = 128, 18%) and hypertension (N = 395, 56%). Complications among these patients based on ACS NSQIP definitions included any complication (N = 132, 19%), serious complication (N = 118, 17%), pneumonia (N = 7, 1.0%), cardiac complication (N = 1, 0.01%), SSI (N = 80, 11.4%), UTI (N = 17, 2.4%), venous thromboembolism (N = 18, 2.5%), renal failure (N = 16, 2.3%), return to the operating room (N = 27, 3.8%), discharge to nursing/rehabilitation (N = 22, 3.1%), and 30-day mortality (N = 9, 1.3%). The calculator provided reasonable estimates of risk for pneumonia (AUC = 0.721), cardiac complication (AUC = 0.773), UTI (AUC = 0.716), and discharge to nursing/rehabilitation (AUC = 0.779) and performed poorly (AUC < 0.7) for all other complications Fig. 1). The ACS-NSQIP risk calculator estimates a similar proportion of risk to actual events in patients with GI-NET but has low specificity for identifying the correct patients for many types of complications. The risk calculator may require modification for some patient populations.

Renal Pelvis Urothelial Carcinoma With Bowel Metastases.

Clin Nucl Med. 2019 Dec;44(12):983-984

Authors: Khoo ACH, Tang WH

Abstract
Urothelial carcinoma is the fourth most common genitourinary tumor with the majority of the tumor involving the urinary bladder. Only 5% involves the renal pelvis and ureter. Metastatic urothelial carcinoma of the renal pelvis frequently involves the lymph nodes, lung, liver, bone, and peritoneum. We share rare interesting F-FDG PET/CT images of a 60-year-old man with metastatic urothelial carcinoma of the renal pelvis to the bowel.
