Bilateral Proximal Tibial Sleeve Fractures in a Child: A Case Report
Introduction: A sleeve fracture classically describes an avulsion of cartilage or periosteum with or without osseous fragments and usually occurs at the inferior margin of the patella. Tibial tubercle sleeve fractures in the skeletally immature are extremely rare.
Case Presentation: In this report the authors describe a 12-year-old boy with no systemic disease and no steroid use who sustained bilateral proximal tibial sleeve fractures whilst playing football. Both ruptures were associated with rupture of the medial patellofemoral ligament and tear of the medial retinaculum. Treatment was performed with primary end-to-end repair, reinforcement with bone anchors and cerclage wires with an excellent outcome.
Conclusions: We feel this rare, currently unclassified variant of a tibial tubercle avulsion fracture should be recognised and consideration taken to adding it to existing classification systems
Regional center for complex colonoscopy: yield of neoplasia in patients with prior incomplete colonoscopy
Background and Aims
Incomplete colonoscopy increases the risk of incident proximal colon cancer postcolonoscopy. Incomplete colonoscopy is often followed by barium enema or CT colonography. We sought to describe the yield of completion colonoscopy in a regional center for complex colonoscopy.
Methods
This is a retrospective cohort study of 520 consecutive patients referred to a single colonoscopist over a 14-year period for completion colonoscopy after a previous incomplete examination.
Results
Colonoscopy was completed to the cecum in 506 of 520 patients (97.3%). A total of 913 conventional adenomas was removed in 277 patients (adenoma detection rate 53.3%). There were 184 adenomas ≥ 1 cm in size or with advanced pathology. There were 525 serrated-class lesions removed in 175 patients, including 54 sessile serrated polyps in 26 patients and 41 hyperplastic polyps greater than 1 cm in 26 patients. Nine colorectal cancers were found. We estimated that approximately 57% of the conventional adenomas, 58% of the sessile serrated polyps, 27% of the hyperplastic polyps, and all 9 cancers detected by the completion colonoscopy were beyond the extent of the previous examination.
Conclusions
The yield of completion colonoscopy in a cohort of patients with previous failed cecal intubation was substantial. Regional centers for complex colonoscopy can provide high rates of cecal intubation in cases of incomplete colonoscopy and high yields of lesions in these cases. The regional center for complex colonoscopy is an important medical service
Recurrence rates after EMR of large sessile serrated polyps
Background
Little is known regarding the recurrence rate after EMR of large (≥20 mm) sessile serrated adenoma/polyps (SSA/Ps).
Objective
To compare the recurrence rate among SSA/Ps and conventional adenomas in patients referred to a specialty practice for EMR.
Design
Retrospective cohort study.
Setting
Academic hospital and a satellite surgery center.
Patients
A total of 362 consecutive patients referred for resection of large (≥20 mm) polyps in the colorectum.
Interventions
All EMRs were performed with a submucosal contrast agent. All subjects had a follow-up surveillance examination (inspection and biopsy of the EMR) at our center.
Main Outcome Measurements
Rates of residual polyp at follow-up examination.
Results
Residual polyp was identified among 8.7% of SSA/Ps compared with 11.1% for conventional adenomas (P = .8).
Limitations
Retrospective design, procedures performed by a single experienced endoscopist, low number of serrated lesions.
Conclusions
The rate of recurrence after EMR of SSA/Ps is similar to the rate after EMR of conventional adenomas
A survey of patient acceptance of resect and discard for diminutive polyps
Background and Aims
Resect and discard is a new paradigm for management of diminutive colon polyps. Little is known regarding whether patients would accept resect and discard. We surveyed colonoscopy patients and their drivers regarding acceptance of resect and discard.
Methods
This was a cross-sectional survey of colonoscopy outpatients and their drivers at two outpatient academic endoscopy centers.
Results
Four hundred fifteen colonoscopy patients and 293 drivers completed the survey (93.5% of all invited participants). Results for the two groups were similar. Overall, 66.3% indicated they would accept resect and discard. Participants who were younger, white, and seen at the ambulatory surgery center (vs the hospital outpatient department) were more likely to accept. Those declining resect and discard were more likely to be willing to pay some amount out-of-pocket to have diminutive polyps checked by pathology (97.1% vs 44.5%). Of those unwilling to accept resect and discard, 49.8% would require a zero chance of cancer in diminutive polyps before accepting resect and discard.
Conclusions
Patient acceptance of resect and discard appears promising but is quite variable. Eliciting individual patient acceptance of resect and discard will be important during initial implementation into clinical practice
Clip Artifact after Closure of Large Colorectal Endoscopic Mucosal Resection Sites: Incidence and Recognition
Background
Clip closure of large colorectal EMR defects sometimes results in bumpy scars that are normal on biopsy. We refer to these as “clip artifact.” If unrecognized, clip artifact can be mistaken for residual polyp, leading to thermal treatment and potential adverse events.
Objective
To describe the incidence of and define predictors of clip artifact.
Design
Review of photographs of scars from consecutive clipped EMR defects.
Setting
University outpatient endoscopy center.
Patients
A total of 284 consecutive patients with clip closure of defects after EMR of lesions 20 mm or larger and follow-up colonoscopy.
Interventions
EMR, clip closure.
Main Outcome Measurements
Incidence of clip artifact.
Results
A total of 303 large polyps met the inclusion criteria. On review of photographs, 96 scars (31.7%) had clip artifact. Clip artifact was associated with increased numbers of clips placed (odds ratio for each additional clip, 1.2; 95% confidence interval, 1.02-1.38) but not polyp histology, size, or location. The rate of residual polyp by histology was 8.9% (27/303), with 21 of 27 scars with residual polyp evident endoscopically. The rate of residual polyp evident only by histology in scars with clip artifact (3/93; 3.2%) was not different from the rate in scars without clip artifact (3/189; 1.6%).
Limitations
Retrospective design. Sites closed primarily with 1 type of clip. Single-operator assessment of endoscopic photographs.
Conclusion
Clip artifact occurred in the scars of approximately one-third of large clipped EMR sites and increased with number of clips placed. Clip artifact could be consistently distinguished from residual polyp by its endoscopic appearance
Determining the adenoma detection rate and adenomas per colonoscopy by photography alone: proof-of-concept study
Background and study aims: The adenoma detection rate (ADR) and adenomas detected per colonoscopy (APC) are measures of the quality of mucosal inspection during colonoscopy. In a resect and discard policy, pathologic assessment for calculation of ADR and APC would not be available. The aim of this study was to determine whether ADR and APC calculation based on photography alone is adequate compared with the pathology-based gold standard.
Patients and methods: A prospective, observational, proof-of-concept study was performed in an academic endoscopy unit. High definition photographs of consecutive polyps were taken, and pathology was estimated by the colonoscopist. Among 121 consecutive patients aged ≥ 50 years who underwent colonoscopy, 268 polyps were removed from 97 patients. Photographs of consecutive polyps were reviewed by a second endoscopist.
Results: The resect and discard policy applied to lesions that were ≤ 5 mm in size. When only photographs of lesions that were ultimately proven to be adenomas were included, the reviewer assessed ADR and APC to be lower than that determined by pathology (absolute reductions of 6.6 % and 0.17, and relative reductions of 12.6 % and 13.1 % in ADR and APC, respectively). When all photographs were included for calculation of ADR and APC, the reviewer determined the ADR to be 3.3 % lower (absolute reduction) and the APC to be the same as the rates determined by pathology.
Conclusions: In a simulated resect and discard strategy, a high-level detector can document adequate ADR and APC by photography alone
