Summary

AI Generated

A retrospective study of 48 resected intraductal papillary mucinous neoplasms found that diffusion-weighted MRI demonstrated diagnostic performance comparable to high-risk stigmata criteria for detecting malignancy.

Diffusion-weighted MRI showed 68% sensitivity and 88% specificity for malignancy detection, with positive diagnostic value of 80%, comparable to high-risk stigmata criteria (81% sensitivity, 70% specificity, 75% positive diagnostic value).
Contrast-enhanced nodules greater than 5 mm (7.4% versus 52.4%, P<0.01) and DW-MRI positivity (12% versus 68%, P<0.01) differed significantly between benign and malignant groups.
HbA1c was higher in the malignant group (5.9 versus 6.7, P=0.03), while age, pancreatitis history, and serum tumor markers did not differ significantly between groups.
Among 48 patients with resected IPMN, high-risk stigmata were present in 52% of cases with a 68% malignancy rate, while worrisome features were present in 42% with a 20% malignancy rate.
Areas of high-grade dysplasia and invasion corresponded to nodule presence and pancreatic duct stenosis on imaging.

Abstract

Introduction

Surgical criteria for pancreatic cyst lesions are determined by the nodule in the cyst and dilation of the main pancreatic duct, but other imaging factors are needed to improve accuracy.

Aims & Methods

Aims: The present study aimed to identify factors of malignancy resection in intraductal papillary mucinous neoplasms (IPMN) treated at our center by evaluating the malignant portions of resected specimens pathologically to extract new imaging features that may serve as novel indices of malignancy.
Methods: Forty-eight patients with IPMN (14 pancreatic head, 31 body to tail, three total pancreatectomies) with a median age of 71 years (range: 38-84) and a male: female ratio of 35: 13 were enrolled. IPMN was divisible into the main pancreatic duct (n=11), branched duct (n=23), and mixed (n=14) types. Furthermore, 27, ten, and 11 cases of IPMA, high-grade IPMN (HG), and IPMC invasive group (C), respectively, were analyzed. [1] Clinical images of the benign group (A) were compared with those of the malignant group (HG+C) ［2]the malignant specimens and areas of invasion were pathologically analyzed (HG+C). ［3] The malignancy detection rate on DW-MRI was then examined; a higher intensity in the lesion than in the surrounding pancreatic parenchyma indicated positivity.

Results

[1] Age (median: 69 years vs. 73 years; P=0.06), history of pancreatitis (15% vs. 10%; P=0.68), and the preoperative serum mean AMY, CA19-9, and CEA positivity rates did not differ significantly between the benign and malignant groups. HbA1c (mean,%) was higher in the malignant group at 5.9 vs. 6.7 (P=0.03). In terms of imaging features, the proportion of main pancreatic ducts with a diameter >10 mm was 22% and 48% in the respective group (P=0.06); the mean cyst diameter was 33 mm vs. 28 mm (P=0.19); the proportion of contrast-enhanced nodules > 5 mm was 7.4% vs. 52.4% (P<0.01); the positivity rate on DW-MRI was 12% vs. 68% (P<0.01), the detection rate of pancreatic duct stenosis rate on MRI was 11% vs. 38% (P＜0.05); worrisome features (WSF) were found in 42% (20/48) of cases; and high-risk stigmata (HRS) were found in 52% (25/48) of cases. The malignancy rate in the WSF and HRS cases was 20% (4/20) and 68% (17/25), respectively.
[ 2] The histological subtypes of the malignant group were gastric (n=5), intestinal (n=8), oncocytic (n=6), and biliary pancreatic (n=2). Areas of high-grade dysplasia and invasion in the HG group and C group, respectively, were consistent with the presence of a nodule and area of pancreatic duct stenosis.
[ 3] When instances of malignancy were treated as positive, the sensitivity, specificity, positive predictive value, negative predictive value, and positive diagnostic value of HRS was 81%, 70%, 68%, 83%, and 75%, respectively, in the 44 cases while the diagnostic performance of DW-MRI was 68%, 88%, 81%, 79%, and 80% for the respective items. The positivity rate for groups A, HG, and C was 12%, 60%, and 78%, respectively.

Conclusion

The present study of resected IPMN found that DW-MRI provided surgical criteria with a diagnostic performance comparable to the HRS criteria.

Abstract

Introduction

Intraprocedural bleeding is a source of technical complexity during endoscopic submucosal dissection (ESD) and may require exchange to coagulation forceps. Spray coagulation is a non-contact, high–peak–voltage mode that combines tissue dissection with powerful coagulation. However, evidence supporting its use in ESD is limited to the stomach.

Aims & Methods

We aimed to evaluate whether spray-coagulation ESD (SP-ESD) improves intraprocedural bleeding control compared to swift ESD (SW-ESD). We analyzed consecutive esophageal, gastric, colonic, and rectal ESDs performed at a tertiary referral center over thirty-six months. SP-ESD was compared to SW-ESD. Assessment of complete procedural video was performed with event-level timestamps. SW-ESD procedures were matched 1:2 to SP-ESD procedures by propensity score on prespecified baseline covariates. The primary outcome was intraprocedural bleeding events. Secondary outcomes were total bleeding time, dissection speed, and coagulation forceps use.

Results

Of 147 eligible ESDs, 91 (60 SP-ESD, 31 SW-ESD) were matched. SP-ESD was associated with fewer bleeding events (mean 1.8 vs 4.2 per procedure; count ratio, .43; 95% CI, .26-.70; P = .001), persisting after accounting for dissection time (rate ratio, .51 per minute; 95% CI, .31-.85). Bleeding time was shorter (median .4 vs 5.5 minutes; ratio of means, .40; 95% CI, .22-.73) and dissection faster (median 16.8 vs 11.6 mm²/min; geometric mean ratio, 1.33; 95% CI, 1.03-1.70). Coagulation forceps were applied a mean of .1 versus 2.6 times per procedure, and 95.0% versus 29.0% were forceps-free (RR, 3.27; 95% CI, 1.79-5.99). R0 resection, en bloc resection, perforation, and delayed bleeding did not differ.

TABLE. Primary and secondary outcomes in the propensity score–matched cohort (n = 91)

Outcome	SW-ESD	SP-ESD	Effect (SP-ESD vs SW-ESD, 95% CI)	P value
Intraprocedural bleeds, mean (primary)	4.2	1.8	CR, .43 (.26-.70)	.001
Bleeding time, min, median	5.5	.4	Ratio of means, .40 (.22-.73)	.003
Dissection speed, mm2/min, median	11.6	16.8	GMR, 1.33 (1.03-1.70)	.027

Conclusion

SP-ESD was associated with substantially less intraprocedural bleeding and coagulation forceps use, and faster dissection without cost in resection quality or safety compared to SW-ESD. Spray coagulation mode can be selected as one of the available electrosurgical modalities to improve bleeding control during ESD.

Abstract

Introduction

Delayed post-polypectomy hemorrhage (DPPH) is caused by a submucosal artery in the ulcer base after polypectomy. Doppler endoscopic probe (DEP) is highly effective in detecting blood flow in medium or large sized arteries in PP induced ulcers (PPIUs). With focal treatment & arterial blood flow obliteration, DEP guided treatment has been reported to prevent severe DPPH throughout the colon (Ref). In contrast, mixed success rates with hemoclip (HC) closure are reported. The HC technique can achieve single-layer mucosal closure but buries submucosal arteries often without obliterating blood flow. It has been reported not to be cost effective, nor efficacious in the left colon or rectum. New treatments are needed to prevent DPPH - a common complication of polypectomy.

Aims & Methods

AIMS: To report final results of a randomized controlled trial (RCT) of blood flow monitoring & focal treatment to prevent DPPH.
METHODS: This was a multicenter RCT of high-risk outpatients having colonoscopies & prospective follow-up (FU). Polyps were removed by EMR &/or thermal coagulation. Patients were stratified by chronic anti-platelet or anti-thrombotic drug use & a PPIU of 10-40 mm; or for those without bleed drugs, PPIU’s were 15-40 mm. After polypectomy, randomization was to either standard management (e.g. following GI guidelines for bleed drugs) or DEP interrogation of PPIU’s & guided treatment with HCs in the PPIU until arterial blood flow was eradicated (1). Patients & their caregivers were blinded to treatments. Prospective FU was by a research coordinator at 7, 14, & 30 days to record complications (e.g. abdominal pain, vomiting, fever or dizziness); rectal bleeding & its severity (e.g. # bloody BM’s/day & # of days bleeding); & whether patients sought ER, clinic, or telemedicine care or hospitalization for bleeding. Major DPPH was diagnosed in patients with severe bleeding for 5 or more days &/or who needed hospitalization. Lesser bleeds were < 4 days, but without hospitalization. Demographic, laboratory, colonoscopic, & pathology results & 30 day outcomes were prospectively recorded on standard forms. Coded data were entered into HIPAA compliant computer files & managed with SAS. This is the final analysis by a biostatistician.

Results

For 180 high risk patients, 92 had standard treatment & 88 had DEP guided treatment. DEP monitoring & focal treatment was quick & easy. Treatment groups were well matched at baseline, including mean age of 68 years, 76% males; 55% on aspirin, 21 % on an anti-coagulant, & 9% on another anti-coagulant. Mean polyp size was 16 mm, most were sessile, & 57% were right colon. There were no drop-outs, severe adverse events, or deaths. However, DEP patients had significantly lower rates of DPPU bleeding – both major & total- as in Table 1.

Table 1. Delayed Post Polypectomy Induced Ulcer Bleeds by Treatment Group

DELAYED BLEEDS	Standard (N = 92)	Doppler (N = 88)	Risk Difference	SE	95% CI’s*	NNT**	****P-Value
Total Delayed PPIU Bleeds	11 (11.96 %)	2 (2.27 %)	9.68%	3.7%	2.36%;17.0%	10.3	0. 0127
Major Delayed Bleeds	***8 (8.7 %)	1 (1.14 %)	7.56 %	3.1%	1.39%;13.7%	13.2	0.0204
Lesser Delayed Bleeds	3 (3.26 %)	1 (1.14 %)	2.12%	2.2%	-2,13%;6.4%	47.1	0.5473

Legend: Treatment results shown as N’s & (%). * 95% CI’s is Confidence Intervals. **NNT is the number needed to treat. *** All were hospitalized except 1 patient with severe bleeding who refused hospitalization during the COVID pandemic. ****P values performed with Fisher exact test

Conclusion

DEP monitoring of arterial blood flow & guided focal treatment resulted in significantly lower rates of severe & total DPPHs than standard medical treatment. This is an easy, safe, & anatomically based method to prevent DPPH throughout the colon and rectum.
