Summary
Hepatic duct diverticulum, a rare choledochal cyst variation, requires classification review. Surgical resection led to a patient
Area of Science:
- Gastroenterology and Hepatobiliary Surgery
- Anatomical Classification Systems
Background:
- Choledochal cysts have been documented since 1852, with Todani's classification proposed in 1977.
- Todani's widely used classification system for choledochal cysts does not encompass all rare anatomical variations.
Observation:
- A 57-year-old woman presented with symptoms including upper abdominal pain, nausea, and vomiting.
- Diagnostic workup revealed cholelithiasis and a right hepatic duct diverticulum.
Findings:
- The patient underwent successful surgical resection of the hepatic duct diverticulum and cholecystectomy.
- Post-operative follow-up at 26 months showed the patient remained asymptomatic.
Implications:
- Hepatic duct diverticulum represents a rare choledochal cyst variant not currently included in Todani's classification.
- There is a need to review and potentially revise Todani's classification to incorporate uncommon choledochal cyst variations.
- Further research is necessary to define optimal diagnostic imaging and treatment strategies for choledochal cysts.

01:27Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
01:22Portal Hypertension
Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
01:17Gross Anatomy of the Liver
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

01:19Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
01:21Hepatic Portal System
The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...
