Cavity shaving for invasive breast cancer conservative surgery: Reduced specimen volume and margin positive rates.

Introduction: The cavity shaving (CS) technique was described in breast conserving surgery to reduce the rate of reoperation avoiding the need for intraoperative margin analysis. This study assesses differences in the rates of involvement of the surgical margin (requiring further surgery) and volume of surgical specimens, depending on the use or not of this technique.

Material And Methods: A retrospective cohort study was conducted in patients with breast carcinoma who underwent breast conserving surgery between 2013 and 2019.

Effectiveness of arterial embolization in recurrent bleeding due to duodenal ulcer during postoperative cardiac surgery.

Upper gastrointestinal bleeding is one of the most frequent complications after cardiac surgery and endoscopic treatment (ET) is often the first-choice procedure. When it fails, surgery can be an option but has significant mortality and morbidity. We propose arterial embolization (TAE: transcatheter arterial embolization) as an alternative treatment in selected cases.

[Laparoscopic liver resection: lessons learned after 132 resections].

Introduction: After 20 years of experience in laparoscopic liver surgery there is still no clear definition of the best approach (totally laparoscopic [TLS] or hand-assisted [HAS]), the indications for surgery, position, instrumentation, immediate and long-term postoperative results, etc.

Aim: To report our experience in laparoscopic liver resections (LLRs).

Patients And Method: Over a period of 10 years we performed 132 LLRs in 129 patients: 112 malignant tumours (90 hepatic metastases; 22 primary malignant tumours) and 20 benign lesions (18 benign tumours; 2 hydatid cysts).

[A new surgical strategy for multiple multiple bilobular liver metastases: right portal occlusion and torniquet in the parenchyma section line].

Right portal vein occlusion plus «in situ split» has recently been reported as a new method to hypertrophy the functional remnant volume (FRV) in 7 days after two-stage liver resection. It is a complex procedure associated with the occlusion of the intrahepatic collaterals between both lobes. We present an original technique for hypertrophying the FRV by occluding the right portal vein and the intrahepatic collaterals: a case is presented of a 35-year-old woman with an intestinal stromal tumour, 14 bilobar metastases and an estimated 24% FRV.

[Delayed right hepatic artery haemorrhage after iatrogenic gallbladder by laparoscopic cholecystectomy that required a liver transplant due to acute liver failure: clinical case and review of the literature].

Introduction: Right hepatic artery (RHA) injury after laparoscopic cholecystectomy (LC) may go unnoticed clinically, but can sometimes cause necrosis of the right lobe. Exceptionally, when the necrosis spreads to segment IV, fulminant liver failure (FLF) may occur, and an urgent liver transplantation (LT) may be required.

Patients And Method: We provide a review of the literature on patients with indication for an LT due to vascular damage caused by bile duct injury following LC.

Post-traumatic hepatic artery pseudoaneurysm treated with endovascular embolization and thrombin injection.

Post-traumatic hepatic artery pseudoaneurysm is uncommon, appearing in approximately 1% of hepatic trauma cases. Most are extrahepatic (80%) and have a late onset. Although they are usually asymptomatic, they should always be treated becasue of the high risk of complications, especially breakage.

[Laparoscopic resection of the left segments of the liver: the "ideal technique" in experienced centres?].

Introduction: The resection of tumours of the anatomical left lobe is normally straightforward using either left lateral sectionectomy (LLSEC) or segmentectomy II or III. Our objective is to present the results of the laparoscopic approach and to consider whether this could be the "ideal technique" in liver surgery units where the surgeons have experience of laparoscopic liver surgery (LLSURG).

Patients And Methods: We have studied patients with resected solid tumours of the anatomical left lobe using LLSURG (n=18): 10 cases with LLSEC and 8 cases with segmentectomy II or III.

[Prognostic factors after resection of colorectal cancer liver metastases].

Introduction: There are many studies that analyse preoperative factors with a poor prognosis in patients undergoing surgery for colorectal carcinoma liver metastases, in order to avoid unnecessary surgery. However, there are few studies that evaluate the intraand postoperative prognostic factors. The aim of this study is to analyse pre-, intra- and postoperative prognostic factors in a series of 210 patients undergoing surgery for colorectal carcinoma liver metastases, with special emphasis on the postoperative factors that can give us information on the aggressiveness of the tumour and the curative effectiveness of the surgery.

[Unilocular macrocystic serous cystoadenoma of the pancreas].

The differential diagnosis between macrocystic serous cystoadenoma and mucinous cystoadenoma is very difficult but is highly important due to the latter's potential for malignant transformation. We present a case of unilocular macrocystic serous cystoadenoma. Due to the impossibility of obtaining an accurate preoperative diagnosis, all macrocystic unilocular lesions, in an appropriate clinical context, must be resected.
