“…Mould (1972) reported on a series of 125 patients who had a previous normal hepatic isotope examination and had a subsequent autopsy where the prevalence of Riedel's lobe was 14.5%. We found a higher prevalence of Riedel's lobe than previously reported (31%) and considerable variation with age.…”

“…Riedel’s lobe is a tongue-like elongation of the right liver, an ectopic lobe is completely independent of the liver parenchyma, which may exist anywhere in the body, and a pedunculated lobe is ALL that is continuous with the liver [ 6 , 13 ]. The prevalence of Riedel’s lobe ranges between 3.3 and14.5% [ 14 , 15 ] and is more frequent in women (4.5–19.4%) than in men (2.1–6.1%) [ 6 ]. Most cases of ALL are asymptomatic; however, torsion [ 16 ], bleeding [ 17 ], or extrinsic compression of the stomach [ 18 ] have been reported.…”

Background Laparoscopic cholecystectomy (LC) is one of the most commonly undertaken procedures worldwide for cholecystolithiasis and cholecystitis. Accessory liver lobe (ALL) is a developmental anomaly defined as an excessive liver lobe composed of a normal liver parenchyma. Some ALL exist on the serosal side of the gallbladder. We herein present two cases of ALL incidentally detected during LC. Case presentation The first case was a 69-year-old woman diagnosed with chronic cholecystitis. LC was performed. ALL was observed anterior to the wall of the gallbladder and resected after clipping. Pathological findings revealed liver tissue with Glisson’s capsule and a lobular structure in ALL. However, communication between the bile ducts of ALL and the main liver was unclear due to surgical heat degeneration. The second case was a 56-year-old woman diagnosed with acute cholecystitis. LC was performed approximately one month after the attack, and ALL attached to the wall of gallbladder. ALL was clipped and completely resected. Pathological findings showed that the bile ducts of ALL might be connected within the wall of gallbladder. Conclusions We presented two cases of ALL attached to the gallbladder encountered during LC. Since ALL contains a normal liver parenchyma, postoperative bleeding or bile leakage may occur if it is inefficiently resected. Therefore, the complete resection of ALL is important to prevent these postoperative complications.

“…There is precedence for a change in liver size and shape after adjacent organs, such as the spleen, are removed surgically [ 18 ]. Additionally, the speculation that the shape of the liver can fit in to the space available is suggested by the wide range of “normal” liver shapes that have been documented [ 19 , 20 ].…”

Gallbladder fossa volume decreased in livers without gallbladders: A cadaveric study

2021

The gallbladder normally lies within a fossa on the visceral surface of the liver. The primary purpose of this study was to determine whether the volume of this fossa was reduced after cholecystectomy. Livers were obtained from embalmed cadavers of 19 females and 15 males with a mean age of 84.1 ± 10.8 yrs. The presence of a gallbladder was assessed, the volume of the irregularly-shaped gallbladder fossa determined from a mold of the fossa, and the dimensions of each fossa were estimated. The mean volume of gallbladder fossae from livers with gallbladders (n = 26; 13 females and 13 males) was 31.01 ± 17.82 ml, which was significantly greater than fossae in livers without gallbladders (n = 8, 6 females, 2 males) which was 8.75 ± 4.72 ml (P<0.0001). This difference still was significant after correcting fossa volume for overall liver weight and length of the femur. Livers with gallbladders had significantly larger dimensions (depth, length, and width) of their fossae molds than did livers without gallbladders (P<0.05). The largest percentage difference between the two groups in these dimensions was in the fossae depth, and there was a significant, positive correlation between all three of these dimensions and the overall volume of the fossae. Even looking only at female livers which tend to be smaller, gallbladder fossa volume was reduced in livers without a gallbladder. Thus, the present study demonstrated that the mean gallbladder fossa volume was significantly decreased in livers lacking gallbladders, even after correcting for the liver weight and size of the individual. While the mechanisms behind these changes in fossa volume currently are unknown, alterations in mechanical pressure relayed to adjacent liver cells after gallbladder removal may play a role in these fossa volume differences.
