In patients with synchronic liver colorectal metastasis, resection of the primary tumor and liver metastases is the only potentially curative strategy. In such cases, there is no consensus on whether resection of the primary tumor and metastases should be performed simultaneously or whether a staged approach should be performed (resection of the primary tumor and after, hepatectomy, or hepatectomy first). Patients with no bowel occlusion and with extensive liver disease are advised neoadjuvant oncological therapy. Similarly, various strategies such as portal vein embolization, liver deprivation, two-staged hepatectomy, and associating liver partition and portal vein ligation are available for patients who do not have a sufficient future liver remnant (generally 30-40% of the total). Therefore, a multidisciplinary approach is required for the treatment of these patients.
The development of surgical techniques, chemotherapy, biological agents, and multidisciplinary approaches have made patients with unresectable colorectal liver metastases eligible for surgery. Many strategies have been developed to allow patients for surgical resection (percutaneous portal vein embolization, liver venous deprivation, parenchyma-sparing liver surgery, reverse strategy, associating liver partition and portal vein ligation for staged hepatectomy, and liver transplantation), the only form of disease control and curative treatment.
Perihilar cholangiocarcinoma presents unique challenges in perioperative management, requiring a comprehensive approach to optimize patient outcomes.
This case study focuses on the multidisciplinary management and innovative interventions performed in the perioperative care of a patient with hilar cholangiocarcinoma.
A comprehensive assessment and treatment strategy involving neoadjuvant therapy and interventional radiology techniques were implemented. Neoadjuvant chemotherapy was administered to reduce tumor size and improve resectability. The crucial role of interventional radiology in managing postoperative complications is highlighted, particularly in the case of massive pulmonary embolism.
The neoadjuvant therapy successfully reduced tumor size, enabling an R0 surgical resection. Additionally, interventional radiology interventions, such as percutaneous pharmaco-mechanical thrombectomy, effectively addressed the life-threatening complication of massive pulmonary embolism.
This article highlights the importance of a collaborative, multidisciplinary approach in managing complex oncological surgeries, especially regarding the hospital’s rescue capacity for severe postoperative complications. Emergent management with interventional radiology had a central role in resolving life-threatening complications.
Mixed neuroendocrine-non-neuroendocrine tumors (MiNEN) are a rare type of tumor formed by two components, a non-neuroendocrine component that is most often an adenocarcinoma and a neuroendocrine tumor, and each of these components must represent at least 30% of the tumor. The origin of this tumor on the ampulla of Vater or periampullary region is more infrequent. Usually, the lesions are highly aggressive and quickly metastasizing, and their biological behavior is dictated by the high grade of the neuroendocrine component. This is the first report of a patient with ampullary MiNEN treated employing a robotic pancreaticoduodenectomy. Although being submitted to aggressive treatment with complete surgical resection followed by systemic therapy, the patient developed early recurrence with hepatic metastatic disease, demonstrating the hostile nature of these tumors.
Intrahepatic cholangiocarcinoma (iCCA) was considered a contraindication for liver transplantation. However, recent studies have shown that highly selected cases of patients with a good response to neoadjuvant therapy may achieve acceptable survival rates when following liver transplantation.
To present two cases of patients with iCCA, without extrahepatic disease, who underwent living donor liver transplantation after receiving neoadjuvant chemotherapy.
Two cases of patients with histopathological diagnosis of locally advanced iCCA, ineligible for resection and without evidence of extrahepatic disease, are presented.
These patients underwent at least nine sessions of neoadjuvant chemotherapy, including Gemcitabine and Cisplatin, with or without the addition of immunobiological agents, resulting in a radiological tumor response. They subsequently underwent living donor liver transplantation. The average follow-up time was 15 months, with no clinical or radiological signs of disease.
In well-selected patients without extrahepatic disease, living donor liver transplantation represents a potential therapeutic option for iCCA.
Bile duct injury (BDI) causes significant sequelae for the patient in terms of morbidity, mortality, and long-term quality of life, and should be managed in centers with expertise. Anatomical variants may contribute to a higher risk of BDI during cholecystectomy.
To report a case of bile duct injury in a patient with situs inversus totalis.
A 42-year-old female patient with a previous history of situs inversus totalis and a BDI was initially operated on simultaneously to the lesion ten years ago by a non-specialized surgeon. She was referred to a specialized center due to recurrent episodes of cholangitis and a cholestatic laboratory pattern. Cholangioresonance revealed a severe anastomotic stricture. Due to her young age and recurrent cholangitis, she was submitted to a redo hepaticojejunostomy with the Hepp-Couinaud technique. To the best of our knowledge, this is the first report of BDI repair in a patient with situs inversus totalis.
The previous hepaticojejunostomy was undone and remade with the Hepp-Couinaud technique high in the hilar plate with a wide opening in the hepatic confluence of the bile ducts towards the left hepatic duct. The previous Roux limb was maintained. Postoperative recovery was uneventful, the drain was removed on the seventh post-operative day, and the patient is now asymptomatic, with normal bilirubin and canalicular enzymes, and no further episodes of cholestasis or cholangitis.
Anatomical variants may increase the difficulty of both cholecystectomy and BDI repair. BDI repair should be performed in a specialized center by formal hepato-pancreato-biliary surgeons to assure a safe perioperative management and a good long-term outcome.
Para-aortic lymph nodes involvement in pancreatic head cancer has been described as an independent adverse prognostic factor. To avoid futile pancreatic resection, we systematically perform para-aortic lymphadenectomy as a first step.
To describe our technique for para-aortic lymphadenectomy.
A 77-year-old female patient, with jaundice and resectable pancreatic head adenocarcinoma, underwent pancreaticoduodenectomy associated with infracolic lymphadenectomy.
The infracolic anterior technique has two main advantages. It is faster and prevents the formation of postoperative adhesions, which can make subsequent surgical interventions more difficult.
We recommend systematic para-aortic lymphadenectomy as the first step of pancreaticoduodenectomy for pancreatic head adenocarcinoma by this approach.
The success of peritoneal dialysis depends on the proper placement and functional longevity of the dialysis catheter. Laparoscopic implantation of a catheter through a rectus sheath tunneling can minimize the risks of catheter failure.
This study aims to describe one-port simplified technique for laparoscopic placement of a peritoneal dialysis catheter with rectus sheath tunneling.
The simplified laparoscopic insertion of a Tenckhoff catheter with rectus sheath tunneling was performed in 16 patients with chronic renal failure.
During the follow-up period, no major complications occurred. Three patients were excluded. One was referred to the renal transplant some weeks after implantation, and one died for other reasons during the follow-up. Another patient needed adhesiolysis due to previous surgery, so an additional port was necessary. The other 13 catheters worked properly, and no postoperative hemorrhage, early leaks, hernia, or catheter migration occurred. One patient had a tunnel infection 11 months after the implant. No peritonitis was observed during the follow-up.
The technique is simple, reproducible, and safe, with good results in catheter function, few complications, and a high catheter survival rate. It does not require a special device or trocar and avoids excessive port sites.
The anorectal anomalies consist in a complex group of birth defects. Laparoscopic-assisted anorectoplasty improved visualization of the rectal fistula and the ability to place the pull-through segment within the elevator muscle complex with minimal dissection. There is no consensus on how the fistula should be managed.
To evaluate the laparoscopic-assisted anorectoplasty and the treatment of the rectal urinary fistula by a bipolar sealing device.
It was performed according to the original description by Georgeson1. Was used 10 mm infraumbilical access portal for 30º optics. The pneumoperitoneum was established with pressure 8-10 cm H2O. Two additional trocars of 5 mm were placed on the right and left of the umbilicus. The dissection started on peritoneal reflection using Ligasure(r). With the reduction in the diameter of the distal rectum was identified the fistula to the urinary tract. The location of the new anus was defined by the location of the external anal sphincter muscle complex, using electro muscle stimulator externally. Finally, it was made an anastomosis between the rectum and the new location of the anus. A Foley urethral probe was left for seven days.
Seven males were operated, six with rectoprostatic and one with rectovesical fistula. The follow-up period ranged from one to four years. The last two patients operated underwent bipolar sealing of the fistula between the rectum and urethra without sutures or surgical ligation. No evidence of urethral leaks was identified.
There are benefits of the laparoscopic-assisted anorectoplasty for the treatment of anorectal anomaly. The use of a bipolar energy source that seals the rectal urinary fistula has provided a significant decrease in the operating time and made the procedure be more elegant.
Once a biliary injury has occurred, repair is done by a hepaticojejunostomy. The most common procedure is to perform a dilatation with balloon with a success of 70 %. Success rates range using biodegradable stents is from 85% to 95%. Biodegradable biliary stents should change the treatment of this complication.
To investigate the use of biodegradable stents in a group of patients with hepaticojejunonostomy strictures.
In a prospective study 16 biodegradable stents were placed in 13 patients with hepaticojejunostomy strictures secondary to bile duct repair of a biliary surgical injury. Average age was 38.7 years (23-67), nine were female and four male. All cases had a percutaneous drainage before at the time of biodegradable stent placement.
In one case, temporary haemobilia was present requiring blood transfusion. In another, pain after stent placement required intravenous medication. In the other 11 patients, hospital discharge was the next morning following stent placement. During the patient´s follow-up, none presented symptoms during the first nine months. One patient presented significant alkaline phosphatase elevation and stricture recurrence was confirmed. One case had recurrence of cholangitis 11 months after the stent placement. 84.6% continued asymptomatic with a mean follow-up of 20 months.
The placement of biodegradable stents is a safe and feasible technique. Was not observed strictures caused by the stent or its degradation. It could substitute balloon dilation in strictures of hepaticojejunostomy.
