Takayasu's arteritis (TA) and inflammatory bowel disease (IBD) are chronic inflammatory granulomatous disorders that have rarely been concomitantly reported in case reports and small case series. Objective. We report a series of seven cases of TA and IBD association in two referral centers with a comprehensive review of literature. Methods. We analyzed retrospectively the electronic medical charts of TA-IBD patients at the University Hospital of Sao Paulo, Brazil, and at the Sheba Medical Center at Tel Aviv University, Israel. Results. Overall, five patients had Crohn's disease (DC) and two had ulcerative colitis (UC), and they were mostly female and non-Asian. All patients developed IBD first and, subsequently, TA. Two underwent colectomy and one ileocecectomy due to IBD activity, while three required cardiovascular surgery due to TA activity. Most patients are currently in clinical remission of both diseases with conventional drug treatment. Conclusion. Although the coexistence of TA and IBD is uncommon, both seem to be strongly associated through pathophysiological pathways.
- A NEW APPROACH FOR HEMORRHOID DISEASE: SELECTIVE DEARTERIALIZATION AND MUCOPEXY WITHOUT DOPPLER GUIDANCE(2021) SOBRADO, Carlos Walter; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.
- Gastric and Duodenal Fistulas in Crohn's Disease, a Surgical Challenge: Report of 5 Cases and a Review of the Literature(2023) SOBRADO JUNIOR, Carlos Walter; VILLELA JUNIOR, Helder de Moura; FACANALI, Carolina Bortolozzo Graciolli; SOBRADO, Lucas Faraco; CAMARGO, Mariane Gouvea Monteiro de; NAHAS, Sergio CarlosObjective: Rare diseaseBackground: Fistulas involving the stomach and duodenum in Crohn's disease are rare (occurring in less than 1% of patients). Here, we reviewed registers from 855 patients with Crohn's disease treated in our service from January 2007 to December 2020 and found 4 cases of duodenal fistula and 1 case of gastric fistula.Case Reports: The fistula origin was in the ileocolic segment in all cases, and all of the patients underwent preoperative optimization with improvement of nutritional status and infection control. They then underwent surgical treatment with resection of the affected segment and duodenal or gastric closure with covering by an omental patch. One case of a duodenal fistula was complicated by duodenal dehiscence. This was treated surgically with duodenojejunostomy. Each of the other patients had an uneventful postoperative course. All patients were successfully cured of their gastroduodenal fistulas, and at the time of this publication, none of them died or had fistula recurrence.Conclusions: Fistulas with the involvement of the stomach and duodenum in patients with Crohn's disease are almost always due to inflammation in the ileum, colon, or previous ileocolic anastomosis. Management of this situation is complex and often requires clinical and surgical assistance; preoperative optimization of the patient's general condition can improve the surgical results. The surgical approach is based on resection of the affected segment and gastric or duodenal closure with covering by an omental patch. Gastrojejunostomy or duodenojejunostomy can be performed in selected patients with larger defects and minor jejunal disease. To prevent recurrence, prophylactic therapy with anti-TNF agents and early endoscopic surveillance are also essential for successful treatment.
- Transanal hemorrhoidal dearterialization: Lessons learned from a personal series of 200 consecutive cases and a proposal for a tailor-made procedure(2020) SOBRADO, Carlos Walter; HORA, Jose Americo Bacchi; SOBRADO, Lucas Faraco; FRUGIS, Marcos Onofre; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground: Transanal hemorrhoidal dearterialization (THD) is an effective treatment for hemorrhoidal disease (HD). However, the surgical technique is not standardized and the results for advanced HD are controversial. The aim of this study was to assess surgical outcomes after a long follow-up and compare total and partial mucopexy. Materials and methods: Between March 2011 and July 2014, THD was offered to patients with symptomatic prolapsed hemorrhoids (Grades II, III and IV). Dearterialization was performed with the guidance of Ultrasound Doppler and mucopexy for prolapsed piles, and regarded as total or partial (if less than 6 mucopexies). Post- operative complications, long-term results and patients ? satisfaction rates were analyzed. Results: 200 consecutive patients were recruited with a mean follow-up of 43 months (range 29 - 57 months). HD distribution was GII (N = 35, 17.5%), GIII (N = 124, 62%), and GIV (N = 41, 20.5%). Postoperative com- plications included transient tenesmus (26,5%), pain (14%) and fecal impaction (2,5%). Recurrence rates were 0, 2,4% and 17,1% for prolapse (p < 0,01) and 2,9%, 4% and 9,8% for bleeding (p = 0,33) in grades II, III and IV, respectively. Total mucopexy resulted in more tenesmus (31,2%) than partial mucopexy (14,5%), (p < 0,01). After 12 weeks of follow-up, 85% of patients were either very satisfied or satisfied; 8,5% were dissatisfied. Conclusion: THD-mucopexy is safe with low overall recurrence. Grade IV HD is associated with more recurrence and postoperative complications. Total mucopexy is associated with more tenesmus, pain and fecal impaction. A tailor-made procedure with selective dearterialization and mucopexy may be the next step in this evolving technique.
- The novel BPRST classification for hemorrhoidal disease: A cohort study and an algorithm for treatment(2021) SOBRADO, Carlos Walter; OBREGON, Carlos de Almeida; SOBRADO, Lucas Faraco; BASSI, Lucas Morales; HORA, Jose Americo Bacchi; SOUSA JUNIOR, Afonso Henrique Silva e; NAHAS, Sergio Carlos; CECCONELLO, IvanBackground: The classification for HD was developed by Goligher in 1980 and does not contemplate important aspects of this disease, which limits its use in guiding treatment. The aim of this study if to apply in clinical practice the new classification for hemorrhoids named BPRST (bleeding, prolapse, reduction, skin tags, thrombosis), to compare it with the original classification proposed by Goligher and to propose an algorithm for treatment. Materials and methods: This is a prospective study conducted at the University of Sao Paulo's teaching hospital and Hospital 9 de Julho. Patients with HD treated from March 2011 to July 2013 were included. Patients were classified according to BPRST and Goligher classifications and treated according to personal experience and most updated guidelines. The association between both classifications and the treatment adopted was compared and an algorithm for treatment was developed. Results: 229 patients were included in this study and 28 patients were lost due to follow-up. According to Goligher, 29, 61, 85 and 26 were classified as grades I, II, III and IV, respectively. According to the BPRST, 23 were classified as stage I, 95 as stage II and 83 as stage III. Six patients classified as Goligher I were reclassified as BPRST stage III and required conventional hemorrhoidectomy, either due to thrombosis (n = 4) or intolerable skin tags (n = 2). The BPRST classification was more closely associated with the type of treatment employed and had few outliers than Goligher (p < 0.001). Conclusion: There are limitations to the use of Goligher's classification in clinical practice. The novel BPRST classification includes important aspects of HD that should be considered when deciding the best treatment option. Our algorithm for treatment contemplates the most commonly used techniques and can help to guide the treatment of this complex disease.
- RISK FACTORS FOR EARLY POSTOPERATIVE COMPLICATIONS IN ACUTE ESFAGOGÁSTRICE ESPLENECTOMIA INFL COLITIS IN THE ERA OF BIOLOGIC THERAPY(2023) SOBRADO, Lucas Faraco; MORI, Fernando Noboru Cabral; FACANALI, Carolina Bortolozzo Graciolli; CAMARGO, Mariane Gouvea Monteiro; NAHAS, Sergio Carlos; SOBRADO, Carlos WalterBackground: Despite major advances in the clinical treatment of inflammatory bowel disease, some patients still present with acute colitis and require emergency surgery. Aims: To evaluate the risk factors for early postoperative complications in patients undergoing surgery for acute colitis in the era of biologic therapy. Methods: Patients with inflammatory bowel disease admitted for acute colitis who underwent total colectomy at a single tertiary hospital from 2012 to 2022 were evaluated. Postoperative complications were graded according to Clavien-Dindo classification (CDC). Patients with more severe complications (CDC >= 2) were compared with those with less severe complications (CDC<2). Results: A total of 46 patients underwent surgery. The indications were: failure of clinical treatment (n=34), patients' or surgeon's preference (n=5), hemorrhage (n=3), toxic megacolon (n=2), and bowel perforation (n=2). There were eight reoperations, 60.9% of postoperative complications classified as CDC >= 2, and three deaths. In univariate analyses, preoperative antibiotics use, ulcerative colitis diagnosis, lower albumin levels at admission, and preoperative hospital stay longer than seven days were associated with more severe postoperative complications. Conclusions: Emergency surgery for acute colitis was associated with a high incidence of postoperative complications. Preoperative use of antibiotics, ulcerative colitis, lower albumin levels at admission, and delaying surgery for more than seven days were associated with more severe early postoperative complications. The use of biologics was not associated with worse outcomes.
- Diagnosis and treatment of constipation: a clinical update based on the Rome IV criteria(2018) SOBRADO, Carlos Walter; CORRêA NETO, Isaac José Felippe; PINTO, Rodrigo Ambar; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanABSTRACT The aim of this study was to evaluate the published professional association guidelines regarding the current diagnosis and treatment of functional intestinal constipation in adults and to compare those guidelines with the authors' experience to standardize actions that aid clinical reasoning and decision-making for medical professionals. A literature search was conducted in the Medline/PubMed, Scielo, EMBASE and Cochrane online databases using the following terms: chronic constipation, diagnosis, management of chronic constipation, Roma IV and surgical treatment. Conclusively, chronic intestinal constipation is a common condition in adults and occurs most frequently in the elderly and in women. Establishing a precise diagnosis of the physiopathology of functional chronic constipation is complex and requires many functional tests in refractory cases. An understanding of intestinal motility and the defecatory process is critical for the appropriate management of chronic functional intestinal constipation, with surgery reserved for cases in which pharmacologic intervention has failed. The information contained in this review article is subject to the critical evaluation of the medical specialist responsible for determining the action plan to be followed within the context of the conditions and clinical status of each individual patient.
- A New Classification for Hemorrhoidal Disease: The Creation of the ""BPRST"" Staging and Its Application in Clinical Practice(2020) SOBRADO JUNIOR, Carlos Walter; OBREGON, Carlos de Almeida; SOUSA JUNIOR, Afonso Henrique da Silva e; SOBRADO, Lucas Faraco; NAHAS, Sergio Carlos; CECCONELLO, IvanPurpose: Present an updated classification for symptomatic hemorrhoids, which not only guides the treatment of internal hemorrhoids but also the treatment of external components. In addition, this new classification includes new treatment alternatives created over the last few years. Methods: Throughout the past 7 years, the authors developed a method to classify patients with symptomatic hemorrhoids. This study, besides presenting this classification proposal, also retrospectively analyzed 149 consecutive patients treated between March 2011 and November 2013 and aimed to evaluate the association between the management adopted with Goligher classification and our proposed BPRST classification. Results: Both classifications had a statistically significant association with the adopted management strategies. However, the BPRST classification tended to have fewer management discrepancies when each stage of disease was individually analyzed. Conclusion: Although there is much disagreement about how the classification of hemorrhoidal disease should be updated, it is accepted that some kind of revision is needed. The BPRST method showed a strong association with the management that should be adopted for each stage of the disease. Further studies are needed for its validation, but the current results are encouraging.
