Home medical nutrition during SARS-CoV-2 pandemic - A position paper.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a worldwide rapidly spreading illness, Coronavirus Disease 2019 (COVID-19). Patients fed enterally and parenterally at home are exposed to the same risk of infection as the general population, but more prone to complications than others. Therefore the guidance for care-givers and care-takers of these patients is needed.

Surgical Repair of Small Bowel Fistulas: Risk Factors of Complications or Fistula Recurrence.

BACKGROUND Definitive surgical repair of persistent fistulas of the small intestine remains a surgical challenge with a high rate of re-fistulation and mortality. The aim of this study was to evaluate the type and incidence of complications after definitive surgical repair, and to identify factors predictive of severe postoperative complications or fistula recurrence. MATERIAL AND METHODS This was a retrospective study of 42 patients who underwent elective surgical repair of a persistent fistula of the small intestine.

Surgical management of the grade C pancreatic fistula after pancreatoduodenectomy.

Background: Surgical management of severe pancreatic fistula after pancreatoduodenectomy remains challenging, and carries high mortality. The aim of this retrospective study was to compare different surgical techniques used at relaparotomy for pancreatic fistula after pancreatoduodenectomy, and to identify factors predictive of failure to rescue.

Methods: A total of 43 patients after pancreatoduodenectomy developed a pancreatic fistula requiring relaparotomy.

Surgical treatment of extra-appendiceal colorectal neuroendocrine tumors.

Background: Extra-appendiceal colorectal neuroendocrine tumors are rare neoplasms with a variable biological behavior.

Materials And Methods: The study group consisted of 15 patients with an extra-appendiceal colorectal neuroendocrine tumor who underwent surgical resection (M/F=3:12, mean age=62.9 years).

Comparison between minimally invasive and open surgical treatment in necrotizing pancreatitis.

Background: Minimal access techniques have gained popularity for the management of necrotizing pancreatitis, but only a few studies compared open necrosectomy with a less invasive treatment. The aim of this study was to evaluate the outcomes of minimally invasive treatment for necrotizing pancreatitis in comparison with open necrosectomy.

Materials And Methods: This retrospective study included 70 patients who underwent minimally invasive intervention or open surgical debridement for necrotizing pancreatitis between January 2007 and December 2014.

Parenchyma-Sparing Pancreatic Resections: With or Without a Pancreaticojejunostomy?

Background/aim: Parenchyma-sparing pancreatic resections are used in low-grade malignant tumors, but result in a high incidence of pancreatic fistula. Pancreaticojejunostomy to the site of resection might decrease the risk of pancreatic fistula. The purpose of this study was to evaluate the influence of pancreaticojejunostomy on the outcomes of parenchyma-sparing resections.

Minimally invasive treatment of infected pancreatic necrosis.

Infected pancreatic necrosis is a challenging complication that worsens prognosis in acute pancreatitis. For years, open necrosectomy has been the mainstay treatment option in infected pancreatic necrosis, although surgical debridement still results in high morbidity and mortality rates. Recently, many reports on minimally invasive treatment in infected pancreatic necrosis have been published.

Walled-off necrosis: safety of watchful waiting.

Background: Asymptomatic pancreatic necrosis should be managed conservatively, regardless of its extent. However, late sequelae and safety of non-interventional management in patients with asymptomatic walled-off necrosis remain unclear.

Aims: The purpose of this study was to report the clinical outcome of outpatient expectant management in a cohort of patients with walled-off necrosis who were discharged asymptomatic after an episode of acute pancreatitis.

Combined minimally invasive management of infected pancreatic necrosis: a case report.

Infected necrosis is a potentially fatal complication of necrotizing pancreatitis. Open surgical debridement is the mainstay management of infected pancreatic necrosis. Over the last decade minimally invasive techniques have been increasingly used for the treatment of infected pancreatic necrosis and their results are encouraging.

Ultrasound-guided percutaneous drainage of infected pancreatic necrosis.

Background: The role of percutaneous drainage in the management of infected pancreatic necrosis remains controversial, and ultrasound-guided technique is rarely used for this indication. The purpose of this study was to evaluate the safety and efficacy of sonographically guided percutaneous catheter drainage for infected pancreatic necrosis.

Methods: The patient group consisted of 16 men and 2 women.

Retroperitoneal minimally invasive pancreatic necrosectomy using single-port access.

Infected pancreatic necrosis is a life-threatening complication of acute pancreatitis that has been traditionally managed with open surgical debridement. Over the last decade, minimally invasive techniques have been increasingly used for the treatment of infected pancreatic necrosis and their results are encouraging. Percutaneous retroperitoneal pancreatic necrosectomy is one of the minimally invasive approaches used for debridement of pancreatic necrosis.

Optimizing management of pancreaticopleural fistulas.

Aim: To evaluate the management of pancreaticopleural fistulas involving early endoscopic instrumentation of the pancreatic duct.

Methods: Eight patients with a spontaneous pancreaticopleural fistula underwent endoscopic retrograde cholangiopancreatography (ERCP) with an intention to stent the site of a ductal disruption as the primary treatment. Imaging features and management were evaluated retrospectively and compared with outcome.

Necrotizing fasciitis: early sonographic diagnosis.

Necrotizing fasciitis is a rare, but potentially fatal bacterial infection of the soft tissues. Establishing the diagnosis at the early stages of the disease remains the greatest challenge. We report a case of necrotizing fasciitis involving the upper extremity.

Mesenteric fibromatosis with intestinal involvement mimicking a gastrointestinal stromal tumour.

Introduction: Mesenteric fibromatosis or intra-abdominal desmoid tumour is a rare proliferative disease affecting the mesentery. It is a locally aggressive tumour that lacks metastatic potential, but the local recurrence is common. Mesenteric fibromatosis with the intestinal involvement can be easily confused with other primary gastrointestinal tumours, especially with that of the mesenchymal origin.

Sonographic findings in groove pancreatitis.

Groove pancreatitis is a rare form of chronic pancreatitis involving the anatomic plane between the pancreatic head and duodenum. The radiographic diagnosis remains challenging, and most patients undergo exploratory laparotomy on suspicion of a periampullary malignancy. The appearance of groove pancreatitis on transabdominal and intraoperative sonography has rarely been reported in the literature.

Gastrointestinal stromal tumors: ultrasonographic spectrum of the disease.

Objective: The purpose of this series was to determine the spectrum of findings on gray scale trans-abdominal ultrasonography (TAUS) in pathologically proven cases of primary gastrointestinal stromal tumors (GISTs) and correlate them with gross morphologic and pathologic findings.

Methods: The series included 18 patients with a primary GIST tumor detected on preoperative TAUS. The ultrasonographic findings were evaluated for features such as tumor size, shape, margin, echogenicity, and presence of fluid components, and the features were compared with morphologic and pathologic findings.

Synchronous occurrence of gastrointestinal stromal tumors and other primary gastrointestinal neoplasms.

Aim: To review clinical and pathologic features of Gastrointestinal stromal tumors (GISTs) occurring synchronously with other primary gastrointestinal neoplasms.

Methods: Twenty-eight patients with primary GIST were treated at our institution between 1989 and 2005. Clinical and pathologic records were reviewed.

[Late malignant melanoma metastases within the abdominal cavity imitating clinically and pathologically a gastrointestinal stromal tumor].

Melanoma is a malignant skin neoplasm that often metastasizes within the abdominal cavity. Melanoma metastases can develop even many years after the primary treatment. Clinical course, microscopic histology, and immunohistochemical profile of melanoma may imitate a gastrointestinal stromal tumor (GIST).

[A case report of severe hypophosphatemia in the course of refeeding syndrome].

This is a case report of 53 year old male who underwent pancreatoduodenectomy for chronic pancreatitis. Two months after the operation the symptoms of severe malnutrition caused by nutrition digestive disorders developed. The patient was admitted to the hospital with the symptoms of severe malnutrition and general poor medical condition.

[Seminoma metastases as a retroperitoneal space tumor].

This is a case report of a testicular tumor, probably seminoma, presenting a retroperitoneal mass. The patient underwent surgical removal of tumor and the possibility of testicular tumor on the basis of histological examination was assumed. However, the histological examination of the testicle did not confirm the diagnosis of seminoma.
