Machine learning-based prediction for incidence of endoscopic retrograde cholangiopancreatography after emergency laparoscopic cholecystectomy: A retrospective, multicenter cohort study.

Background: Laparoscopic cholecystectomy is the preferred treatment for symptomatic cholelithiasis and acute cholecystitis, with increasing applications even in severe cases. However, the possibility of postoperative endoscopic retrograde cholangiopancreatography (ERCP) to manage choledocholithiasis or biliary injuries poses significant clinical challenges. This study aimed to develop a predictive model for ERCP incidence following emergency laparoscopic cholecystectomy using advanced machine learning techniques.

Machine learning-based prediction of postoperative mortality in emergency colorectal surgery: A retrospective, multicenter cohort study using Tokushukai medical database.

Background: Although prognostic factors associated with mortality in patients with emergency colorectal surgery have been identified, an accurate mortality risk assessment is still necessary to determine the range of therapeutic resources in accordance with the severity of patients. We established machine-learning models to predict in-hospital mortality for patients who had emergency colorectal surgery using clinical data at admission and attempted to identify prognostic factors associated with in-hospital mortality.

Methods: This retrospective cohort study included adult patients undergoing emergency colorectal surgery in 42 hospitals between 2012 and 2020.

A unique strategy for large-bowel perforation with ventriculoperitoneal shunt: Conversion to ventriculoatrial shunt: A case report.

Introduction: Large-bowel perforation can lead to critical sepsis, and urgent intervention including surgery is indispensable to control systemic infection. Here, we describe a strategy for large-bowel perforation using a ventriculoperitoneal shunt.

Case Presentation: A 74-year-old Japanese female with a history of cerebral aneurysm clipping and ventriculoperitoneal shunting due to aneurysmal subarachnoid hemorrhage presented with lower abdominal pain, fever, and disturbed consciousness.

A rare trigger for acute appendicitis leading to small bowel obstruction: traditional serrated adenoma of the appendiceal foramen.

This is the first documented case of traditional serrated adenoma (TSA) of the appendiceal foramen that triggered acute appendicitis resulting in small bowel obstruction (SBO). An 88-year-old Japanese man presented with abdominal pain, distension, and appetite loss. Computed tomography demonstrated distended ileum adherent to cecum with thickened walls.

Challenging management of familial adenomatous polyposis with advanced colorectal cancer: laparoscopic partial resection and cold snare polypectomy.

 Prophylactic extended colectomy may be indicated because most surgically untreated patients with familial adenomatous polyposis (FAP) develop colorectal cancer (CRC) in their lifetime. However, some patients refuse to undergo surgery to avoid degradation of their quality of life. We report that FAP is controllable with laparoscopic partial resection and postoperative polypectomy even when complicated by advanced CRC.

Successful surgical resection of ruptured cholangiolocellular carcinoma: A rare case of a primary hepatic tumor.

Spontaneous rupture is one of the most fatal complications of hepatic tumors such as hepatocellular carcinoma. In fact, many studies have shown that the in-hospital and 30-d mortality rates are as high as 25%-100%. Cholangiolocellular carcinoma (CoCC) is a rare primary hepatic tumor, usually small in size, that is thought to originate from the ductules and/or canals of Hering.

A rare case of an infected tracheal diverticulum requiring emergency intervention: A case report.

Introduction: Recent advancement in radiological imaging has revealed an increasing amount of asymptomatic abnormalities. Tracheal diverticula are relatively rare entities and are incidentally found on radiological imaging such as computed tomography. Here, we present a case of an infected tracheal diverticulum presenting as a paratracheal mass, which required emergency intervention.
