| 1 | Pancreatic necrosis:Complications and changing trend of treatment显示文摘Incidence of acute pancreatitis seems to be increasing in the Western countries and has been associated with significantly increased morbidity. Nearly 80% of the patients with acute pancreatitis undergo resolution; some develop complications including pancreatic necrosis. Infection of pancreatic necrosis is the leading cause of death in these patients. A significant portion of these patients needs surgical interventions. Traditionally, the 'gold standard' procedure has been the open surgical necrosectomy, which is now being completed by the relatively lesser invasive interventions. Minimally invasive surgical(MIS) procedures include endoscopic drainage, percutaneous image-guided catheter drainage, and retroperitoneal drainage. This review article discusses the open and MIS interventions for pancreatic necrosis with each having its own respective benefits and disadvantages are covered. | Mamoon Ur Rashid Ishtiaq Hussain Sundas Jehanzeb Waqas Ullah Saeed Ali Akriti Gupta Jain Neelam Khetpal Sarfraz Ahmad | 2019 | World Journal of Gastrointestinal Surgery2019，11，4： | 7 |
| 2 | Splenic injuries secondary to colonoscopy:Rare but serious complication显示文摘BACKGROUND Colonoscopy is a safe and routine diagnostic and therapeutic procedure for evaluation of large bowel diseases.Most common procedure related complications include bleeding and perforation but rarely a splenic Injury.AIM To investigate the reason for colonoscopy,presentation of patient with spleen injury,types of injury,diagnosis,management and outcomes of patients METHODS A structured search on four databases was done and 45 articles with 68 patients were selected.The reason for colonoscopy,presentation of patient with spleen injury,types of injury,diagnosis,management and outcomes of patients were identified and analyzed using SPSS.RESULTS The mean age of the patients was 62.7 years with 64%females.Twenty two percent had a complete splenic rupture with colonoscopy while 63%had subcapsular hematoma,spleen laceration and spleen avulsion.The most common reason for colonoscopy was screening(46%)followed by diagnostic colonoscopy(28%).Eighty seven percent of patients presented with abdominal pain.Patients with spleen rupture mostly required splenectomy(47%),while minor spleen hematomas and lacerations were managed conservatively(38%).Six percent of the patients were managed with proximal splenic artery splenic embolization and 4%were managed with laparoscopic repair.The overall mortality was 10%while 77%had complete recovery.The reason of colonoscopy against presentation specifically,abdominal pain showed no statistical significance P=0.69.The indication of colonoscopy had no significant impact on incidence of splenic injury(P=0.89).Majority of the patients(47%)were managed with splenectomy while the rest were managed conservatively(P=0.04).This association was moderately strong at a cramer’s V test(0.34).The Fisher exact test showed a higher mortality with spleen rupture(P=0.028).CONCLUSION Spleen rupture due to colonoscopy is a significant concern and is associated with high mortality.The management of the patients can be individualized based on clinical presentation. | Waqas Ullah Mamoon Ur Rashid Asif Mehmood Yousaf Zafar Ishtiaq Hussain Deepika Sarvepalli Muhammad Khalid Hasan | 2020 | World Journal of Gastrointestinal Surgery2020，12，2： | 4 |
| 3 | Colon mucosal neoplasia referred for endoscopic mucosal resection:Recurrence of adenomas and prediction of submucosal invasion显示文摘BACKGROUND Endoscopic mucosal resection(EMR)is an effective and minimally invasive alternative to surgery for large polyps and laterally spreading lesions.Gross morphology and surface characteristics may help predict submucosal invasion of the lesion(SMIL)during endoscopic evaluation.This is one of the largest singlecenter studies reporting endoscopic mucosal resection for larger(≥20 mm)colorectal lesions in the United States.AIM To determine the recurrence rate of adenomas and endoscopic features that may predict submucosal invasion of colonic mucosal neoplasia.METHODS This is a retrospective cohort study of all the patients referred for endoscopic mucosal resection for lesions≥20 mm,spanning a period from January 2013 to February 2017.The main outcome measure was identifying features that may predict submucosal invasion of mucosal lesions and predict recurrence of adenomas on follow-up surveillance colonoscopy performed at 4-6 mo.RESULTS A total of 480 patients with 500 lesions were included in the study.The median age was 68(Inter quantile range:14)with 52%males.The most common lesion location was ascending colon(161;32%).Paris classification 0-IIa(Flat elevation of mucosa-316;63.2%);Kudo Pit Pattern IIIs(192;38%)and Granular surface morphology(260;52%)were most prevalent.Submucosal invasion was present in 23(4.6%)out of 500 lesions.The independent risk factors for SMIL were Kudo Pit Pattern IIIL+IV and V(Odds ratio:4.5;P value<0.004)and Paris classification 0-IIc(Odds ratio:18.2;P value<0.01).Out of 500,354 post-endoscopic mucosal resection scars were examined at surveillance colonoscopy.Recurrence was noted in 21.8%(77 cases).CONCLUSION There was overall low prevalence of SMIL in our study.Kudo pit pattern(IIIL+IV and V)and Paris classification 0-IIc were the only factors identified as an independent risk factor for submucosal invasion.The independent risk factor for recurrence was adenoma size(>40 mm).Almost all recurrences(98.8%)were treated endoscopically. | Mamoon Ur Rashid Neelam Khetpal Hammad Zafar Saeed Ali Evgeny Idrisov Yuan Du Assaf Stein Deepanshu Jain Muhammad Khalid Hasan | 2020 | World Journal of Gastrointestinal Endoscopy2020，12，7： | 3 |
