Simplified technique in total pancreatectomy with islet cell autotransplantation after Frey's procedure: a case report.

Background: The selection of the surgical approach for chronic pancreatitis (CP) is determined by various factors including inflammatory location, presence of pancreatic duct dilatation, or possibility of cancer. Total pancreatectomy (TP), with or without islet cell autotransplantation, is considered for patients with refractory CP after the failure of other surgical treatments. Considering the increasing incidence of CP requiring surgical treatment, the number of cases in which TP is performed after previous surgical treatment is expected to increase.

A successful complete resection for multidrug-resistant giant gastrointestinal stromal tumor invading the transverse colon with multiple liver metastases in a young female: a case report.

Background: Gastrointestinal stromal tumors (GISTs) are rare in young people and are often detected after becoming symptomatic or at an advanced stage. Herein, we report a case of complete reduction surgery for a substantially large malignant gastric GIST with multiple liver metastases in a young woman who successfully resulted in R0 surgery.

Case Presentation: An 18-year-old woman presented to our hospital with anorexia and vomiting, and was diagnosed with a 17 cm gastric GIST with transverse colon invasion and multiple liver metastases.

Secondary ileal lymph node metastases from rectal cancer: a case report.

Background: Colorectal cancer can invade adjacent organs, but rarely metastasizes to the regional lymph nodes (LNs) of the invaded organ. Herein, we report a case of rectal cancer invading the ileum and metastasized to the regional ileal LNs.

Case Presentation: A 77-year-old male presented abdominal pain and anorexia, diagnosed with rectal cancer invading the small intestine and concurrently metastasized to the regional LN of the intestine and liver.

A case of multidrug-resistant intractable pylephlebitis and intra-abdominal abscess due to perforated appendicitis successfully treated with open abdominal management.

Background: Pylephlebitis, a rare and lethal form of portal venous septic thrombophlebitis, often arises from infections in regions drained by the portal vein. Herein, we report a case of peritonitis with portal vein thrombosis due to acute severe appendicitis, managed with intensive intraperitoneal drainage via open abdominal management (OAM).

Case Presentation: A 19-year-old male with severe appendicitis, liver abscesses, and portal vein thrombosis developed septic shock and multi-organ failure.

Pancreaticoduodenectomy after bilirubin adsorption for distal cholangiocarcinoma with severe obstructive jaundice refractory to repeat preoperative endoscopic biliary drainage: a case report.

The necessity of biliary drainage before pancreaticoduodenectomy remains controversial in cases involving malignant obstructive jaundice; however, the benefits of biliary drainage have been reported in cases with severe hyperbilirubinemia. Herein, we present the case of a 61-year-old man suffering from jaundice due to distal cholangiocarcinoma. In this case, obstructive jaundice was refractory to repeat endoscopic drainage and bilirubin adsorption.

A unique case of a typical pancreatic ductal adenocarcinoma that initially presented with a cystic component but underwent morphological changes.

A 66-year-old man was initially suspected of having a microcystic serous cystic neoplasm based on magnetic resonance imaging findings of a multifocal mass measuring 46 mm in the pancreatic head, with a cystic component showing a high signal on T2-weighted images. The tumor marker levels were within normal limits. However, contrast-enhanced computed tomography revealed thick cyst walls with delayed staining, which was atypical for serous cystic neoplasms; therefore, the patient was followed up closely.

Laparoscopic minor liver resection for hepatocellular carcinoma.

Background: Previous studies have suggested that laparoscopic liver resection for hepatocellular carcinoma is associated with lower postoperative complications compared with open liver resection.

Methods: We conducted a retrospective analysis of 109 hepatocellular carcinoma patients who underwent minor liver resection at a Japanese tertiary care hospital from November 2010 to December 2022.

Results: The laparoscopic liver resection group experienced significantly lower median intraoperative blood loss compared with the open liver resection group (P = 0.

Percutaneous Transhepatic Gallbladder Intervention as a Bridge to Cholecystectomy: Aspiration or Drainage?

Background: Percutaneous transhepatic gallbladder aspiration (PTGBA) and percutaneous transhepatic gallbladder drainage (PTGBD) are often the first-line treatments for acute cholecystitis, instead of surgical cholecystectomy. This retrospective study aimed to compare the treatment outcomes of PTGBA and PTGBD and evaluate the risks of treatment failure among patients undergoing PTGBA before surgical cholecystectomy.

Methods: We retrospectively reviewed 99 patients who underwent PTGBA or PTGBD as the first-line treatment before surgical cholecystectomy, between January 2014 and December 2019.

Repeat hepatectomy for massive liver metastases from pheochromocytoma: a case report.

In malignant pheochromocytoma, the survival benefit of metastasectomy remains unclear. However, excessive catecholamines secreted from pheochromocytomas can cause cardiovascular and cerebrovascular complications. Debulking metastasectomy can be performed to reduce excess catecholamine secretion when curative resection is impossible.

Multivisceral resection for primary pancreatic signet ring cell carcinoma.

Primary pancreatic signet ring cell carcinoma (PPSRCC) is a rare and aggressive tumor with poor prognosis. Here, we report a case of PPSRCC treated with curative surgery. A 49-year-old man presented with right mid-abdominal pain.

Surgical management of appendicitis in patients with human immunodeficiency virus (HIV) positivity: a propensity score-matched analysis in a base hospital for HIV treatment in Japan.

Purpose: To investigate the impact of human immunodeficiency virus (HIV) infection on surgical outcomes after appendectomy.

Methods: Data on patients who underwent appendectomy for acute appendicitis between 2010 and 2020 at our hospital were investigated retrospectively. The patients were classified into HIV-positive and HIV-negative groups using propensity score-matching (PSM) analysis, adjusting for the five reported risk factors for postoperative complications: age, sex, Blumberg's sign, C-reactive protein level, and white blood cell count.

Outcomes following cholecystectomy in human immunodeficiency virus-positive patients treated with antiretroviral therapy: A retrospective cohort study.

The number of the human immunodeficiency virus (HIV)-positive patients are increasing worldwide, and more HIV-positive patients are undergoing urgent or elective cholecystectomy. There is still insufficient evidence on the relationship between surgical complications of cholecystectomy and antiviral status in HIV-positive patients. The purpose of the present study is to evaluate surgical outcomes after cholecystectomy in HIV-positive patients.

Liver resection in a patient with persistent positive PCR test for coronavirus disease 2019 (COVID-19): a case report.

Background: The perioperative mortality rate is high in patients with coronavirus disease 2019 (COVID-19), and infection control measures for medical care providers must be considered. Therefore, the timing for surgery in patients recovering from COVID-19 is difficult.

Case Presentation: A 65-year-old man was admitted to a hospital with a diagnosis of moderate COVID-19.

Estimation of Physiologic Ability and Surgical Stress (E-PASS) Predicts Postoperative Major Complications After Hepato-Pancreato Biliary Surgery in the Elderly.

Background: As society ages, an increasing number of elderly patients require hepato-pancreato-biliary (HPB) surgery. We investigated the risk factors for complications in elderly patients undergoing HPB surgery using surgical risk scoring models.

Methods: We retrospectively investigated 184 elderly patients (≥ 65 years old) who underwent HPB surgery, including the liver, pancreas, bile duct, and/or gallbladder resection, with exemption to simple cholecystectomy between January 2017 and December 2019.

Surgical treatment for a rare case of duodenal gangliocytic paraganglioma accompanied with lymph node metastasis.

We report a rare case of duodenal gangliocytic paraganglioma accompanied with lymph node metastasis. An asymptomatic 58-year-old woman was admitted for the evaluation of abnormal liver enzyme test results. Abdominal computed tomography and upper gastrointestinal endoscopy revealed a 27-mm pedunculated tumor of the papilla of Vater.

Proposal of new treatment algorithm for gastric cancer liver metastases: Up-front surgery or conversion surgery?

Hepatectomy for gastric cancer liver metastases (GCLM) has a 5-year survival rate of 9-42%; however, indications for hepatectomy remain unclear. Many researchers have reported prognostic factors for GCLM after hepatectomy, but surgical indications vary according to the literature. Furthermore, the indication for optimal candidates for neoadjuvant chemotherapy and intensive chemotherapy is also unclear.

Elevation in creatine kinase isoenzyme-MM associated with hepatocellular carcinoma: a case report and review of literature.

We report the case of a 79-year-old woman with hepatocellular carcinoma (HCC) who presented with creatine kinase (CK)-MM elevation. On admission, her serum CK-MM level exceeded 4000 IU/L (normal, 44-206 IU/L), and computed tomography revealed two HCCs in hepatic segment VIII (23 mm, 86 mm). The patient denied experiencing muscular symptoms such as weakness or pain.

Hepatectomy for liver metastases from cervical cancer with portal vein tumor thrombosis: a case report.

The prognosis of patients with liver metastasis of cervical cancer is poor with an extremely short survival period, and there have been no reports of cervical cancer complicated by portal vein tumor thrombosis (PVTT). We report a case of cervical cancer developing liver metastasis with PVTT. A 49-year-old woman developed liver metastasis from cervical cancer with PVTT.

Intraoperative indocyanine green fluorescence navigation facilitates complete removal of lymph node metastases from hepatocellular carcinoma.

Indocyanine green (ICG) is a fluorescent dye that selectively accumulates in primary hepatocellular carcinoma (HCC) as well as in extrahepatic metastases of HCC. Reported here is a case of metachronous lymph node (LN) metastases from HCC that were resected using ICG fluorescence navigation. A man in his 70s was referred to this department for suspected LN metastasis from HCC.
