You are a medical research assistant. Your task is to query the medical textbook library database and extract detailed, high-yield information on the following surgical topics for MBBS-level education: 1. Hemorrhoids (haemorrhoids) - definition, epidemiology, anatomy, classification (degrees/types), pathophysiology, clinical features, examination, investigations, management (conservative, medical, surgical procedures like rubber band ligation, sclerotherapy, hemorrhoidectomy), complications, prognosis 2. Anal Fissure - definition, epidemiology, anatomy, pathophysiology, classification (acute vs chronic), clinical features, examination, investigations, differential diagnosis, management (conservative, medical, surgical - lateral internal sphincterotomy, fissurectomy), complications 3. Rectal Prolapse - definition, types (mucosal vs full thickness), epidemiology, anatomy, pathophysiology, clinical features, examination, investigations, management (Delorme, Altemeier, abdominal rectopexy, Thiersch procedure), complications, prognosis Use the following SQL queries to find and extract relevant content: Step 1: Find relevant books ```sql SELECT isbn, title, speciality FROM v_book_overview ORDER BY speciality LIMIT 20 ``` Step 2: Search headings for each topic ```sql SELECT title, book_title, '/textbooks/' || block_file_path AS file_path, line_number, para_line_ranges, para_count FROM headings_fts WHERE headings_fts MATCH 'hemorrhoids haemorrhoids' ORDER BY rank LIMIT 10 ``` ```sql SELECT title, book_title, '/textbooks/' || block_file_path AS file_path, line_number, para_line_ranges, para_count FROM headings_fts WHERE headings_fts MATCH 'anal fissure' ORDER BY rank LIMIT 10 ``` ```sql SELECT title, book_title, '/textbooks/' || block_file_path AS file_path, line_number, para_line_ranges, para_count FROM headings_fts WHERE headings_fts MATCH 'rectal prolapse' ORDER BY rank LIMIT 10 ``` Step 3: Read the content from the most relevant files found in Step 2. Read at least 150 lines from each major section found. Step 4: Also search paragraphs for specific details: ```sql SELECT book_title, section_heading, '/textbooks/' || block_file_path AS file_path, line_start, line_end, snippet(paragraphs_fts, 0, '>>>', '<<<', '...', 30) as snippet FROM paragraphs_fts WHERE paragraphs_fts MATCH 'hemorrhoid classification degrees internal external' ORDER BY rank LIMIT 8 ``` ```sql SELECT book_title, section_heading, '/textbooks/' || block_file_path AS file_path, line_start, line_end, snippet(paragraphs_fts, 0, '>>>', '<<<', '...', 30) as snippet FROM paragraphs_fts WHERE paragraphs_fts MATCH 'lateral internal sphincterotomy fissure' ORDER BY rank LIMIT 8 ``` ```sql SELECT book_title, section_heading, '/textbooks/' || block_file_path AS file_path, line_start, line_end, snippet(paragraphs_fts, 0, '>>>', '<<<', '...', 30) as snippet FROM paragraphs_fts WHERE paragraphs_fts MATCH 'rectal prolapse Delorme Altemeier rectopexy' ORDER BY rank LIMIT 8 ``` Read ALL relevant file sections found. Return a comprehensive, structured summary of everything you found for each topic, including direct quotes and specific details from the textbooks. Include the book titles and page references. Be thorough - this will be used to write a comprehensive surgical note.
