| 1 | Lessons learned from an audit of 1250 anal fistula patients operated at a single center:A retrospective review显示文摘BACKGROUND A complex anal fistula is a challenging disease to manage.AIM To review the experience and insights gained in treating a large cohort of patients at an exclusive fistula center.METHODS Anal fistulas operated on by a single surgeon over 14 years were analyzed.Preoperative magnetic resonance imaging was done in all patients.Four procedures were performed:fistulotomy;two novel sphincter-saving procedures,proximal superficial cauterization of the internal opening and regular emptying and curettage of fistula tracts(PERFACT)and transanal opening of intersphincteric space(TROPIS),and anal fistula plug.PERFACT was initiated before TROPIS.As per the institutional GFRI algorithm,fistulotomy was done in simple fistulas,and TROPIS was done in complex fistulas.Fistulas with associated abscesses were treated by definitive surgery.Incontinence was evaluated objectively by Vaizey incontinence scores.RESULTS A total of 1351 anal fistula operations were performed in 1250 patients.The overall fistula healing rate was 19.4%in anal fistula plug(n=56),50.3%in PERFACT(n=175),86%in TROPIS(n=408),and 98.6%in fistulotomy(n=611)patients.Continence did not change significantly after surgery in any group.As per the new algorithm,1019 patients were operated with either the fistulotomy or TROPIS procedure.The overall success rate was 93.5%in those patients.In a subgroup analysis,the overall healing rate in supralevator,horseshoe,and fistulas with an associated abscess was 82%,85.8%,and 90.6%,respectively.The 90.6%healing rate in fistulas with an associated abscess was comparable to that of fistulas with no abscess(94.5%,P=0.057,not significant).CONCLUSION Fistulotomy had a high 98.6%healing rate in simple fistulas without deterioration of continence if the patient selection was done judiciously.The sphincter-sparing procedure,TROPIS,was safe,with a satisfactory 86%healing rate for complex fistulas.This is the largest anal fistula series to date. | Pankaj Garg Baljit Kaur Ankita Goyal Vipul D Yagnik Sushil Dawka Geetha R Menon | 2021 | World Journal of Gastrointestinal Surgery2021，13，4： | 8 |
| 2 | All ileo-cecal ulcers are not Crohn's:Changing perspectives of symptomatic ileocecal ulcers显示文摘AIM To investigated clinical,endoscopic and histopathological parameters of the patients presenting with ileocecal ulcers on colonoscopy.METHODS Consecutive symptomatic patients undergoing colonoscopy,and diagnosed to have ulcerations in the ileocecal(I/C) region,were enrolled.Biopsy was obtained and theirclinical presentation and outcome were recorded.RESULTS Out of 1632 colonoscopies,104 patients had ulcerations in the I/C region and were included in the study.Their median age was 44.5 years and 59% were males.The predominant presentation was lower GI bleed(55,53%),pain abdomen ± diarrhea(36,35%),fever(32,31%),and diarrhea alone(9,9%).On colonoscopy,terminal ileum was entered in 96(92%) cases.The distribution of ulcers was as follows:Ileum alone 40%(38/96),cecum alone 33%(32/96),and both ileum plus cecum 27%(26/96).The ulcers were multiple in 98% and in 34% there were additional ulcers elsewhere in colon.Based on clinical presentation and investigations,the etiology of ulcers was classified into infective causes(43%) and noninfective causes(57%).Fourteen patients(13%) were diagnosed to have Crohn's disease(CD).CONCLUSION Non-specific ileocecal ulcers are most common ulcers seen in ileo-cecal region.And if all infections are clubbed together then infection is the most common(> 40%) cause of ulcerations of the I/C region.Cecal involvement and fever are important clues to infective cause.On the contrary CD account for only 13% cases as a cause of ileo-cecalulcers.So all symptomatic patients with I/C ulcers on colonoscopy are not Crohn's. | Jay Toshniwal Romesh Chawlani Amit Thawrani Rajesh Sharma Anil Arora Hardik L Kotecha Mohan Goyal Vijendra Kirnake Pankaj Jain Pankaj Tyagi Naresh Bansal Munish Sachdeva Piyush Ranjan Mandhir Kumar Praveen Sharma Vikas Singla Rinkesh Bansal Vineet Shah Sunita Bhalla Ashish Kumar | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，7： | 5 |
| 3 | Diagnosis of anorectal tuberculosis by polymerase chain reaction,GeneXpert and histopathology in 1336 samples in 776 anal fistula patients显示文摘BACKGROUND The association of tuberculosis(TB)with anal fistulas can make its treatment quite difficult.The main challenge is timely detection of TB in anal fistulas and its proper management.There is little data available on diagnosis and management of TB in anal fistulas.AIM To detect TB in fistula-in-ano patients were analyzed in different methods utilized.METHODS A retrospective analysis of different methods,polymerase chain-reaction(PCR),GeneXpert and histopathology(HPE),utilized to detect tuberculosis in fistula-inano patients,treated between 2014-2020,was performed.The sampling was done for tissue(fistula tract lining)and pus(when available).The detection rate of various tests to detect TB and prevalence rate of TB in simple vs complex fistulae were studied.RESULTS In 1336 samples(776 patients)tested,TB was detected in 133 samples(122 patients).TB was detected in 52/703(7.4%)samples tested by PCR-tissue,in 77/331(23.2%)samples tested by PCR-pus,3/197(1.5%)samples tested with HPE-tissue and 1/105(0.9%)samples tested by GeneXpert.To detect TB,PCRtissue was significantly better than HPE-tissue(52/703 vs 3/197 respectively)(P=0.0012,significant,Fisher’s exact test)and PCR-pus was significantly better than PCR-tissue(77/331 vs 52/703 respectively)(P<0.00001,significant,Fisher’s exact test).TB fistulas were more complex than non-tuberculous fistulas[78/113(69%)vs 278/727(44.3%)respectively](P<0.00001,significant,Fisher’s exact test)but the overall healing rate was similar in tuberculous and non-tuberculous fistula groups[90/102(88.2%)vs 518/556(93.2%)respectively](P=0.10,not significant,Fisher’s exact test).CONCLUSION This is the largest study of anorectal TB to be published.The detection of TB by polymerase chain-reaction was significantly higher than by histopathology and GeneXpert.Amongst polymerase chain-reaction,pus had a higher detection rate than tissue.TB fistulas were more complex than non-tuberculous fistulas but aggressive diagnosis and meticulous treatment led to comparable overall success rates in both groups. | Pankaj Garg Ankita Goyal Vipul D Yagnik Sushil Dawka Geetha R Menon | 2021 | World Journal of Gastrointestinal Surgery2021，13，4： | 3 |

| 12 | Protection of Viola odorata L.against Neurodegenerative Diseases:Potential of the Extract and Major Phytoconstituents显示文摘Background:Neurodegenerative diseases cause cognitive impairment owing to neuronal death and deterioration.Only a few brain-protecting chemical investigations yielded neuroprotective medications.Viola odoata L.is a traditional medicinal herb that has lately been shown to have strong pharmacological effectiveness against major neurological illnesses with fewer adverse effects.Objective:The objective of the current review is to provide a thorough overview of the key biologically active components and extract of Viola odorata L.in their capacity to safeguard nerve cells.Methods:Science Direct,PubMed,Springer Nature,and Google Scholar were scoured for relevant articles using the terms“Viola odorata L.”,and in the heading and abstract or main text,“neuroprotective activity”,“neurode-generative disease”,“pharmacological potential”,and“therapeutic activity”along with“extract”or“phytocon-stituents”.Neuroprotective activity of Viola odorata L.extract or phytoconstituents were used to classify and investigate the articles that passed the screening process.Results:A total of one hundred twenty one papers were reviewed based on the collected data.The following topics have been elaborated upon in the text:pathological factors of neurodegenerative diseases;role of medic-inal plants in neurodegenerative diseases;Viola odorata L.taxonomy,pharmacological activities,toxicity and adverse effect;neuroprotective activity of extract and various active components of Viola odorata L.The primary phytocomponents of Viola odorata L.were discovered to be anthocyanins,flavonoids,melatonin,salicylic acid,cumarins and various alkaloids,which are primarily responsible for its neuroprotective action.These natural plant compounds can boost antioxidant levels,reduce harmful oxidants,alleviate nerve pain,decrease the pro-duction of pro-inflammatory cytokines such as IL-6,IL-1β,and TNF-α��,lower the total amount of nitrite produced,and trigger various neuroprotective mechanisms in the nervous system.It has been also concluded in several in-vestigations that Viola odorata L.extract and some of its major molecular components can protect against toxic affronts,either directly through neuroprotective mechanisms or indirectly through antioxidant properties.Conclusion:Despite the need for further research,the presence of bioactive components in Viola odarata L.that hold the potential to become effective neuroprotective therapeutic agents shows its potential use in treating neurodegenerative diseases characterized by neuro-inflammation and neurotransmitter deficiency. | Sunny Dhiman Shivali Singla Inder Kumar Priyankul Palia Pankaj Kumar Sachin Goyal | 2023 | Clinical Complementary Medicine and Pharmacology2023，3，3： | 0 |
