Colecistitis aguda en vesícula biliar izquierda. Presentación de un caso resuelto en forma segura por vía laparoscópica / Acute cholecystitis in a left sided gallbladder safely managed by laparoscopic surgery

RESUMEN La vesícula izquierda (VI) es una rara anomalía de la vía biliar que, cuando enferma, no suele dar sín tomas diferentes de aquella normoposicionada, haciendo infrecuente su diagnóstico preoperatorio. Presentamos el caso de una colecistitis aguda en un paciente con VI, resuelto en forma segura por vía laparoscópica. Un paciente ingresa por un cuadro típico de colecistitis aguda. Como hallazgo in traoperatorio se constata una vesícula biliar inflamada, ubicada en posición siniestra. Se modificó la ubicación de los puertos de trabajo y se realizó colangiografía transvesicular por punción, antes de iniciar la disección del hilio vesicular. Luego de identificar el conducto cístico, se realizó colangiografía transcística que confirmó la anatomía de la vía biliar completa y expedita. Se completó la colecistec tomía laparoscópica en forma segura. El hallazgo de una VI obliga al cirujano a cambiar la técnica de una colecistectomía laparoscópica. Esta anomalía incrementa el riesgo de lesiones de la vía biliar. La disección cuidadosa del hilio vesicular logrando una visión crítica de seguridad y el uso de colangiogra fía intraoperatoria son de extrema importancia para una colecistectomía segura.

ABSTRACT Left-sided gallbladder (LSGB) is a rare bile duct abnormality, usually found during a cholecystectomy. Symptoms usually do not differ from those of a normally positioned gallbladder, making the preoperative diagnosis extremely uncommon. We report the case of an acute cholecystitis in a patient whit LSGB, safely managed with laparoscopic surgery. A 24-year-old male patient was admitted to our institution with clinical and radiological signs of acute cholecystitis. The intraoperative finding of an acute cholecystitis in a LSGB made us modify ports positioning and a cholangiograhy was done by direct puncture of the gallbladder before hilum dissection. After the cystic duct was identified, a transcystic cholangiography was performed which confirmed a complete and clear bile duct anatomy and laparoscopic cholecystectomy was safely completed. The intraoperative finding of a LSGB makes the surgeon change some aspects of the usual technique to perform a safe cholecystectomy as LSGB significantly increases the risk of common bile duct injuries. Meticulous dissection of the gallbladder hilum to achieve a critical view of safety and the systematic use of intraoperative cholangiography are extremely important to perform a safe laparoscopic cholecystectomy.

Customized left-sided hepatectomy and bile duct resection for perihilar cholangiocarcinoma in a patient with left-sided gallbladder and multiple combined anomalies

Left-sided gallbladder (LSGB) is a rare anomaly, but it is often associated with multiple combined variations of the liver anatomy. We present the case of a patient with LSGB who underwent successful resection of perihilar cholangiocarcinoma. The patient was a 67-year-old male who presented with upper abdominal pain and obstructive jaundice. Initial imaging studies led to the diagnosis of Bismuth-Corlette type IIIB perihilar cholangiocarcinoma. Due to the unique location of the gallbladder and combined multiple hepatic anomalies, LSGB was highly suspected. During surgery after hilar dissection, we recognized that the tumor was located at the imaginary hilar bile duct bifurcation, but its actual location was corresponding to the biliary confluence of the left median and lateral sections. The extent of resection included extended left lateral sectionectomy, caudate lobe resection, and bile duct resection. Since some of the umbilical portion of the portal vein was invaded, it was resected and repaired with a portal vein branch patch. Due to anatomical variation of the biliary system, only one right-sided duct was reconstructed. The patient recovered uneventfully without any complication. LSGB should be recognized as a constellation of multiple hepatic anomalies, and therefore, thorough investigations are necessary to enable the performance of safe hepatic and biliary resections.

Left-sided Gallbladder with Intrahepatic Portal Vein Anomalies: A Single Center Experiences

PURPOSE: The goal of this article was to characterize and explain the etiology of a left-sided gallbladders with intrahepatic portal vein anomalies, and these cases of this unusual anatomy were all encountered at a single center. METHODS: We reviewed the movies recorded during surgery, the database information and the preoperative radiologic examinations of 1,141 patients who underwent cholecystectomies at our institution between August 2007 and July 2010 to assess the presence of left-sided gallbladder and its combined anomalies. RESULTS: Four of 1141 patients (0.35%) were diagnosed with left-sided gallbladder. In all the cases, the gallbladder was located on the left side of the falciform ligament, under the left lobe of the liver with typical abnormal intrahepatic portal venous branching. The right posterior portal vein came directly from the main portal vein, and the right anterior portal vein originated from the left portal vein, but the ligamentum teres joined to the left branch of the portal vein in the liver. CONCLUSION: Left-sided gallbladder with intrahepatic portal venous branching anomaly resulted from the defective development of the central portion of the liver rather than from abnormal regression of the left umbilical vein with persistence of the right umbilical vein.

Laparoscopic Cholecystectomy in Patients with a Left-sided Gallbladder

Laparoscopic cholecystectomy has been widely performed as the gold standard for patients suffering with symptomatic gallstone disease. However, conversion to open cholecystectomy is a dilemma when the surgeon encounters a variant biliary anomaly. A gallbladder lying to the left of the round ligament represents a rare congenital anomaly, which is termed as a left-sided gallbladder. The true left-sided gallbladder, situated on the inferior aspect of the left lobe of the liver, is extremely rare and this represents a truly ectopic gallbladder that may developmentally arise as a second gallbladder from the left hepatic duct. This is accompanied by the disappearance of the normal gallbladder on the right side. We report here on 2 cases of left-sided gallbladder that were successfully treated with laparoscopic cholecystectomy at Hallym Medical Center. In both cases, the true left-sided gallbladders were identified intraoperatively. The round ligament was indeed located in its normal position, and the gallbladder was located to the left of the round ligament, which is a type of malposition known as sinistroposition. The operation was carried out in the usual manner with the trocars placed their usual location. Although operations can be carried out with using the standard port sites, a better arrangement for laparoscopic cholecystectomy consists of more medial positioning of the gallbladder-retracting port and placement of the right hand operating port to the left side of the round ligament.

Preduodenal Portal Vein and Left Sided Gallbladder in Hepatolithiasis Patient: A case report

A preduodenal portal vein is a rare anomaly. A left-sided gallbladder is also a rare anatomical variant that may be occasionally combined with a preduodenal portal vein. We report here a patient with multiple biliary stones whose preduodenal portal vein was discovered at operation. The anomaly was a preduodenal portal vein associated with a left-sided gallbladder, which is very rare. This is the first case reported in Korea. An abnormal location of the round ligament to the right side can make the gallbladder appear to be a left-sided gallbladder. Our case belongs to this category. This patient had multiple biliary stones in the intrahepatic duct, the common bile duct, and the gallbladder. We treated him with a cholecystec tomy, choledochotomy, and choledochoscopic stone extraction using a basket, and electrohydraulic lithotripter. All procedures were done using a laparoscopic method. The patient was treated well with no complication.

Left-sided Gallbladder: 2 cases / 한국간담췌외과학회지

Left-sided gallbladder, a rare congenital anomaly, is defined as a gallbladder located to the left of the round ligament. Rarer is the definitely diseased left-sided gallbladder in the literature. The authors experienced two true type cases of the left-sided gallbladder. One case was associated with portal vein anomaly.
