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.
- 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.
- Anorectal Mucosal Melanoma: A Case Report and Literature Review(2021) JUNIOR, Jose Donizeti de Meira; SOBRADO, Lucas Faraco; GUZELA, Vivian M.; NAHAS, Sergio Carlos; SOBRADO, Carlos WalterObjective: Rare disease Background: Anorectal mucosal melanoma (AMM) is a rare and aggressive neoplasm, with a 5-year survival rate of 10%. Due to its rarity and nonspecific symptoms, the diagnosis is often made late. Surgical resection remains the criterion standard for treatment of anorectal melanoma. Case Report: We present the case of an 81-year-old woman presenting with hematochezia, anal secretion, tenesmus, difficulty in defecation, and perianal pain. On physical examination, there was a prolapse of a 5-cm melanocytic nodule in the anal canal, hard on palpation. Biopsy confirmed anorectal melanoma. Staging revealed anal and metastatic disease, with adrenal, lymphatic, and hepatic involvement. As the patient continued to have bleeding, severe pain, and difficulty in defecation, she was submitted to a wide local excision. At 5-month followup, the anal lesion had relapsed, and the patient died 10 months after the procedure. Conclusions: AMM is a rare and extremely aggressive tumor. Symptoms are nonspecific but early diagnosis should be pursued to allow curative treatment. Surgical resection with free margins is the goal of surgical treatment. New therapies are being studied, including immunotherapy, which can improve the dismal prognosis of this rare disease.
