Preoperative transarterial chemoembolization for laparoscopic liver resection in Child A cirrhotic patients with hepatocellular carcinoma.

Purpose: Laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) offers better short-term results than open surgery with similar long-term results although it is technically difficult due to the risk of bleeding.

Methods: This study included patients with HCC in Child A cirrhosis who underwent TACE before LLR between 2009 and 2019. The primary endpoint was to analyze the intraoperative and early results of this technique.

Results of treatment of papillary thyroid microcarcinoma adapted to risk of recurrence.

Background: The incidence of papillary thyroid microcarcinoma (PTMC) is increasing.

Objective: To analyze the long-term prognosis of PTMC.

Method: Study population: patients with a histopathological diagnosis of PTMC (size ≤ 1 cm) treated according to the risk of recurrence of the Latin American Thyroid Society.

Case report of Tourniquet ALPPS and simultaneous sleeve gastrectomy: A valuable association to achieve an adequate future liver remnant in obese patients.

Introduction: Obesity represents a risk factor in case of major hepatectomy, because the future liver remnant (FLR) must be proportional with body weight. To avoid post-hepatectomy liver failure, and further increase the ratio between FLR and body weight, we performed a bariatric procedure in the first stage of the ALPPS technique.

Patient Concerns: Fifty-four-year-old woman, with morbid obesity (BMI 58.

A New Surgical Technique Variant of Partial ALPPS (Tourniquet Partial-ALPPS).

Objective: We present a new variant of partial-ALPPS (p-ALPPS) "Tourniquet partial-ALPPS (Tp-ALPPS)", with the aim of reducing aggressiveness during stage 1.

Summary Background Data: Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) results in liver regeneration in only 9 days. Due to its high initial morbidity and mortality, less aggressive variants were designed.

Associating Liver Partition and Portal Vein Ligation for Staged Hepatectomy Tourniquet as a Resource for Hepatic Transplant in Patient With Hepatic Adenomatosis: A Case Report.

Background: Hepatic adenomatosis is defined as the presence of more than 10 adenomatous lesions seated on a healthy liver. The most frequent complication is bleeding, presenting a risk of malignant neoplasms of less than 10%.

Clinical Case: We present a case of a 28-year-old woman with polycystic ovary syndrome treated with oral contraceptives for 10 years.

ALPPS for hepatocarcinoma under cirrhosis: a feasible alternative to portal vein embolization.

Hepatocellular carcinoma (HCC) is one of the most common and malignant tumors. Preoperative portal vein embolization (PVE) is currently the most accepted treatment before major hepatic resection for HCC in patients with liver fibrosis or cirrhosis and associated insufficient future liver remnant (FLR). In the last decade, associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) technique has been described to obtain an increase of volume regarding PVE and a decrease of drop out.

Evolution of gastroesophageal reflux after laparoscopic vertical gastrectomy. A radiographic, manometric and pH-metric study.

Introduction: the relationship between laparoscopic vertical gastrectomy (LVG) and gastroesophageal reflux (GER) is still controversial. Therefore, its study is of great interest in order to obtain definitive conclusions. The goal of the study was to establish whether LVG modifies pH-metric GER in obese patients and to analyze the associated factors.

Fulminant liver failure secondary to submassive hepatic necrosis in a patient treated with Orlistat. A case report.

Orlistat is an intestinal lipase inhibitor drug that is recommended in obese patients along with a hypocaloric diet. Although the most frequent secondary effect is steatorrhea, fulminant liver failure has also been associated with this drug, which has required liver transplantation in 3 patients. We present the case of a 42-year-old obese male.

Cooperation in surgery of the 21 century.

The need for healthcare cooperation in low- and middle-income countries is known and is implemented day by day. However, the surgical sanitary assistance in these countries in the 21 century is very controversial, as it is still below desirable levels and entails complex solutions. On the other hand, the number of surgeons seeking to get involved is increasing progressively.

Primary hyperparathyroidism associated with MEN 1: Experience in 71 cases.

Introduction: Primary hyperparathyroidism (pHPT) in MEN 1 is characterized by multiglandular disease and early involvement of parathyroid glands at different times. Persistence and recurrence range from 25%-35%. The purpose was: a) to describe the experience and the treatment of patients with pHPT in MEN 1; b) to analyze the variables related with clinical presentation and recurrence.

Positron emission tomography/computed tomography in patients with hepatocellular carcinoma undergoing liver transplantation. Useful, necessary or irrelevant?

Hepatocellular Carcinoma (HCC) is an aggressive tumor entity, with the only curative options being surgical resection or orthotopic liver transplantation (OLT). The presence of one single tumor nodule of less than 5 centimeters diameter or a maximum of 3 nodules, with the largest of these not exceeding 3 centimeters (Milan criteria) constitute the clinical situation in which the best results for OLT in patients with HCC have been achieved. The survival of patients fulfilling the Milan criteria after transplantation is comparable to patients with similar tumor stages without cirrhosis, undergoing hepatic resection.

[Splenic late infarction after laparoscopic gastrectomy: a case report].

Introduction: Laparoscopic gastrectomy has emerged in recent years as an effective technique for the treatment of morbid obesity due to low mortality morbidity rates. Its complications include dehiscence suture line, and others such as splenic infarction. We discuss a case of splenic infarction after laparoscopic gastrectomy.

[Additional primary malignancies in patients with gastrointestinal stromal tumors. Proposal for a new classification].

Additional primary malignancies in patients with gastrointestinal stromal tumor (GIST) is not only common but of growing interest in the scientific literature. This association is of great importance in terms of clinical challenge, diagnosis and therapy as well as for the prognosis impact it implies. In the published series there is a tendency to group these patients to determine the specific and distinguishable characteristics of GIST associated with other malignancies.

Utility of 18 fludeoxyglucose in preoperative positon-emission tomography-computed tomography (PET-CT) in the early diagnosis of exocrine pancreatic cancer: A study of 139 resected cases.

Introduction: In pancreatic ductal adenocarcinoma (PDA), surgical resection is the only curative treatment, but due to its late clinical presentation only 15-25% patients are candidates for curative resection. The aim of this prospective, single-center study is to determine the diagnostic utility of preoperative PET-CT for early detection of PDA and early panIN lesions.

Methods: We studied the histopathological features of PDA and different panIN lesions in 139 surgical samples from patients undergoing pancreatic resection (from 2010-2014), comparing these results with preoperative PET-CT and MDCT study.

Prognostic factors in resected pancreatic neuroendocrine tumours: Experience in 95 patients.

Introduction: The aim of this study was to analyze prognostic factors for survival and recurrence in patients with resected pancreatic neuroendocrine tumors (PNT).

Methods: Medical records of 95 patients with resected PNT were retrospectively reviewed. The variables studied were: age, sex, form of presentation (sporadic/familial tumors), functionality, type of tumor, localization, type of surgery, tumor size, multifocal tumors and recurrent rate.

An 84-year-old woman presented to her local emergency department for abdominal pain. Her medical history included hemodialysis in the treatment of chronic renal failure, Parkinson's disease, chronic atrial fibrillation, chronic constipation, appendicectomy and cholecystectomy. The patient complained of diffuse abdominal pain for 4 days, associated with nausea and vomiting in the last 24 hours.

Groove pancreatitis vs. pancreatic adenocarcinoma: A review of 8 cases.

Introduction: Groove pancreatitis (PS) is an uncommon clinical situation and radiologically it can mimic carcinoma of the periampullary area. The aim of this paper is to study a series of 8 patients who underwent surgery with preoperative diagnosis of pancreatic head mass and subsequent pathological diagnosis of PS.

Methods: In our series, 6 were men and 2 women, with an average age of 51,9 years.

Indication for liver transplantation in a patient with a history of a gastric lymphoma.

The indication for liver transplantation in patients with history of lymphoma is little-known, and the references documented in the medical literature are still limited. We present the case of a 63-year-old man who was diagnosed with chronic hepatopathy due to HBV 15 years ago. He was operated on for hepatocellular carcinoma in the segment VI of the liver 4 years ago, finding a macronodular liver cirrhosis during the surgery.
