RESUMEN

Giant gallbladder (GGB) is a rare condition and its pathogenesis could not be explained clearly. It can result from cholelithiasis, chronic cholecystitis or neoplasm, but more rarely if created congenitally. Adequate vasculatization should support the development of this entity. A 47-year-old lady presented with a dull pain and right upper quadrant abdominal mass. A computed tomography scan showed 27 × 25 × 12 cms cystic mass expanding to the right illiac fossae, surrounded by a homogenous capsule. There were neither stones nor mass in the biliary tract and total cholecystectomy was done. Patient recovered well without signs of cholestasis 5 years postoperatively. A few cases of giant benign gall bladder have been reported in literature; however, no study has tried to investigate the mechanism of its etiology. To support the enlargement of the tissue or organ there must be some growth factors along with adequate vascularization. Vascular endothelial growth factor (VEGF) serum level and VEGF messenger ribonucleic acid (mRNA) gene expression were increased in this case. This GGB case suggests a congenital factor as its etiology. Cholecystectomy may relieve uncomfortable symptoms with good results. The incidence of GGB accompanied by increased serum VEGF levels and mRNA gene expression supports the hypothesis that VEGF plays a major role in supporting the vasculogenesis of GGBs.

RESUMEN

INTRODUCTION: Conjoined twins are rare, high-stakes cases requiring complex management. This report presents thoraco-omphalopagus conjoined twins who shared parts of liver and abdominal wall. The main obstacle in separating these patients was liver fusion. PRESENTATION OF CASE: Two-year-old female conjoined twins presented with liver fusion between segments 2 and 3 in twin A and segments 2 and 4A in twin B. Liver separation was performed using the modified liver hanging maneuver. After separating the triangular ligaments and surrounding adhesions, a 12-Fr Foley catheter was inserted under the fused liver, suspending it upward and producing a clear separation plane. Liver separation required only 32 min. No notable bleeding or bile leakage was observed. DISCUSSION: The liver hanging maneuver was originally used as an adjunct technique for liver tumor hepatectomy. We used this technique to separate the fused livers in conjoined twins. The advantages of LHM include potentially reducing excess manipulation, which may result in parenchyma and vascular pedicle injury, and facilitating bleeding control, thereby reducing the operation time. CONCLUSION: The liver hanging maneuver using a conventional Foley catheter is a simple and useful method for separating fused livers in conjoined twins.

RESUMEN

Liver resection in secondary liver tumors may associated with the consequences of posthepatectomy liver failure (PHLF). Systematic extended right posterior sectionectomy (SERPS) is offered as an alternative to resect secondary liver tumors in segment 6-7 with vascular invasion of right hepatic vein, with less risk of PHLF compared to right hepatectomy. This case series is important to demonstrate the effectivity and safety of SERPS procedure performed in developing country. Cases presentation: The authors reported the case of four patients that underwent SERPS procedure due to metachronous and synchronous liver metastases caused by gastric gastrointestinal stromal tumor and colorectal cancer. Thulium doped fiber laser and harmonic scalpel were used as an energy device. Intra and postoperative parameters were evaluated. SERPS data was collected in 2020-2021 at Prof. dr. R.D. Kandou General Hospital. There were no postoperative complications and no tumor recurrences were found in all four patients in two years surveillance. Clinical discussion: Liver resection poses a relatively moderate risk of mortality and morbidity. Nowadays, parenchyma-sparing liver surgery is the procedure of choice compared to major liver resection whenever feasible. SERPS was first developed to minimize the need for major resection. SERPS may serve as a first-choice procedure due to its superior safety and comparable effectivity compared to major hepatectomy. Conclusion: SERPS is a safe and promising alternative for secondary liver tumors at segments 6-7 and right hepatic vein vascular invasion, compared to right hepatectomy. Thus, minimizing the risk of PHLF by saving a larger volume of future liver remnant.

RESUMEN

INTRODUCTION: Several modalities are used to improve the outcome of liver resection surgery. Laser-based surgery may become promising option; therefore we aim to report our experience regarding the efficacy and safety of Thulium-Doped Fiber Laser (TDFL) 1940 nm in liver parenchyma resection. METHODS: A cross sectional study in which patients with pre-existing liver pathology during July 2019 and July 2020 were randomly assigned to receive liver resection using TDFL integrated with raman laser emitting at 1940 nm and 1470 nm wavelength. Data on estimated blood loss during liver transection, liver transection speed, morbidity rate, and postoperative variables including complications, length of hospital stay (days), and mortality were analyzed. RESULTS: A total of 17 consecutive liver resections were performed, among them are 7 major and 11 minor hepatectomies. The Multipulse TM+1470 were used on 8 procedures consisted of 1 major and 7 minor hepatectomies, the mean amount of blood loss during operation and liver transection was 628.13 ± 141.31 mL and 294.63 ± 94.81 ml, respectively. The mean liver transection speed was 1.52 ± 0.27 cm2/min. No biliary leak, post-hepatectomy-liver failure, and mortality were reported. CONCLUSION: TDFL provided by Multipulse TM+1470 is an effective and safe tool for liver surgery, providing good hemostasis and allowing for safe and effective exposure of vascular. Further study with larger samples might be needed proved the efficacy and safety of TDFL in liver surgery.
