| 1 | Delayed gastric emptying following pancreaticoduodenectomy:Incidence,risk factors,and healthcare utilization显示文摘AIM To characterize incidence and risk factors for delayed gastric emptying(DGE) following pancreaticoduodenectomy and examine its implications on healthcare utilization. METHODS A prospectively-maintained database was reviewed. DGE was classified using International Study Group of Pancreatic Surgery criteria. Patients who developed DGE and those who did not were compared. RESULTS Two hundred and seventy-six patients underwent pancreaticoduodenectomy(PD)(> 80% pyloruspreserving, antecolic-reconstruction). DGE developed in 49 patients(17.8%): 5.1% grade B, 3.6% grade C. Demographic, clinical, and operative variables were similar between patients with DGE and those without. DGE patients were more likely to present multiplecomplications(32.6% vs 4.4%, ≥ 3 complications, P < 0.001), including postoperative pancreatic fistula(POPF)(42.9% vs 18.9%, P = 0.001) and intra-abdominal abscess(IAA)(16.3% vs 4.0%, P = 0.012). Patients with DGE had longer hospital stay(median, 12 d vs 7 d, P < 0.001) and were more likely to require transitional care upon discharge(24.5% vs 6.6%, P < 0.001). On multivariate analysis, predictors for DGE included POPF [OR = 3.39(1.35-8.52), P = 0.009] and IAA [OR = 1.51(1.03-2.22), P = 0.035].CONCLUSION Although DGE occurred in < 20% of patients after PD, it was associated with increased healthcare utilization. Patients with POPF and IAA were at risk for DGE. Anticipating DGE can help individualize care and allocate resources to high-risk patients. | Somala Mohammed George Van Buren II Amy Mc Elhany Eric J Silberfein William E Fisher | 2017 | World Journal of Gastrointestinal Surgery2017，9，3： | 13 |
| 2 | Pancreatic endometrial cyst mimics mucinous cystic neoplasm of the pancreas显示文摘Pancreatic cysts include a variety of benign, premalignant, and malignant lesions. Endometrial cysts in the pancreas are exceedingly rare lesions that are difficult to diagnose pre-operatively. This report describes the findings in a 43-year-old patient with a recent episode of acute pancreatitis who presented with a large cyst in the tail of the pancreas. Imaging demonstrated a loculated pancreatic cyst, and cyst fluid aspiration revealed an elevated amylase and carcinoembryonic antigen. The patient experienced an interval worsening of abdominal pain, fatigue, diarrhea, and a 15-pound weight loss 3 mo after the initial episode of pancreatitis. With concern for a possible pre-malignant lesion, the patient underwent a laparoscopic distal pancreatectomy with splenectomy, which revealed a 16cm×12cm×4cm lesion. Final histopathology was consistent with an intra-pancreatic endometrial cyst. Here we discuss the overlapping imaging and laboratory features of pancreatic endometrial cysts and mucinous cystic neoplasms of the pancreas. | Michael A Mederos Nicole Villafane Sadhna Dhingra Carlos Farinas Amy Mc Elhany William E Fisher George Van Buren II | 2017 | World Journal of Gastroenterology2017，23，6： | 7 |
| 3 | Combined pars plana vitrectomy and Baerveldt glaucoma implant placement for refractory glaucoma显示文摘AIM: To evaluate outcomes of combined pars plana vitrectomy and Baerveldt glaucoma implant(PPV-BGI)placement for refractory glaucoma.·METHODS: The medical records of 92 eyes(89patients) that underwent PPV-BGI were retrospectively reviewed, including 43 eyes with neovascular glaucoma(NVG) and 49 eyes with other types of glaucoma(non-NVG).·RESULTS: Outcome measures were visual acuity(VA),intraocular pressure(IOP), glaucoma medical therapy,complications, and success [VA >hand motions(HM),IOP ≥6 mm Hg and ≤21 mm Hg, no subsequent glaucoma surgery]. Cumulative success rates for the non-NVG group and NVG group were 79% and 40% at1 y, respectively(P =0.038). No difference in the rates of surgical success were found between pars plana and anterior chamber tube placement. Preoperative IOP(mean±SD) was 30.3±11.7 mm Hg in the Non-NVG group and 40.0 ±10.6 mm Hg in the NVG group, and IOP was reduced to 15±9.5 mm Hg in the non-NVG group and 15±10.5 mm Hg in the NVG at 1y. Number of glaucoma medications(mean ±SD) decreased from 2.7 ±1.3 in the non-NVG group and 2.8 ±1.3 in the NVG group preoperatively to 0.76 ±1.18 in the non-NVG group and0.51±1.00 in the NVG group at 1y. Improvement in VA of≥2 Snellen lines was observed in 25(27%) eyes,although only 33% of non-NVG eyes and 2.3% of NVG eyes maintained VA better than 20/200 at 1y. Nonclearingvitreous hemorrhage was the most common postoperative complication occurring in 16(17%) eyes,and postoperative suprachoroidal hemorrhages developed in 5(5.4%) eyes.·CONCLUSION: PPV-BGI is a viable surgical option for eyes with refractory glaucoma, but visual outcomes are frequently poor because of ocular comorbidities,especially in eyes with NVG. The location of tube placement does not influence surgical outcome and should be left to the discretion of the surgeon. | Thalmon R.Campagnoli Sung Soo Kim William E.Smiddy Steve J.Gedde Donald L.Budenz Richard K.Parrish II Paul F.Palmberg William Feuer Wei Shi | 2015 | International Journal of Ophthalmology(English edition)2015，8，5： | 3 |
