• Theme centers on surgical healing and ulcer management in the GI tract, tracing how gastric ulcers and post-adrenalectomy lesions influenced healing of gastro-intestinal anastomoses and postoperative outcomes [7], [8], [14], [17], [19].

• Theme on gastric secretion regulation and stomach physiology, including studies of stimulation/inhibition of gastric secretion and foundational stomach physiology, reflecting mechanistic links to digestion [4], [9], [20].

• Theme on intestinal obstruction pathology and outcomes, combining etiological analysis (volvulus, adhesions), epidemiology/mortality, and patterns of high intestinal stasis to illuminate disease mechanisms [2], [3], [10], [16].

• Theme on biliary system anatomy, metabolism, and secretion, integrating bile acids metabolism, biliary duct anomalies, and cysts with hepatobiliary physiology and pathology [5], [6], [12], [15].
