Deep learning radio-clinical signatures for predicting neoadjuvant chemotherapy response and prognosis from pretreatment CT images of locally advanced gastric cancer patients.

Background: Early noninvasive screening of patients who would benefit from neoadjuvant chemotherapy (NCT) is essential for personalized treatment of locally advanced gastric cancer (LAGC). The aim of this study was to identify radio-clinical signatures from pretreatment oversampled computed tomography (CT) images to predict the response to NCT and prognosis of LAGC patients.

Methods: LAGC patients were retrospectively recruited from six hospitals from January 2008 to December 2021.

Case report: Malignant melanoma of the lower limb with gastric metastasis.

Introduction: Malignant melanoma with gastric metastasis is extremely rare. We report a case of gastric metastasis caused by malignant melanoma of the lower limb.

Case Presentation: A 60-year-old woman was hospitalized for left plantar pain.

Case report: Laparoscopic-assisted distal gastrectomy for gastric cancer in a patient with situs inversus totalis.

Background: Situs inversus totalis (SIT) is a rare congenital disease with a series of clinical features characterized by a mirror image distribution of the viscera to the normal anatomy.

Case Presentation: This study aims to report a 63-year-old male SIT patient with gastric cancer with a preoperative diagnosis of stage IIB gastric cancer (cT3N0M0), who underwent a preoperative multi-disciplinary treatment (MDT) discussion and an abdominal enhancement CT for visceral evaluation to ensure a successful operation. A laparoscopic-assisted distal gastrectomy including D2 lymph node dissection and Billroth I reconstruction was successfully performed.

Left-sided appendicitis due to anatomical variation: A case report.

Introduction: Left-sided appendicitis is a rare condition, and we report a patient with left abdominal heterotopia of the right colon complicated by acute appendicitis in the left lower quadrant.

Case Presentation: A 39-year-old male was admitted to hospital following left lower abdominal pain for 1 day. Imaging examination by abdominal CT showed that the appendix was not clearly seen, and a mass was found in the left lower abdomen.

Intussusception Related to Small Intestinal Lipomas: A Case Report and Review of the Literature.

Introduction: Adult intussusception is a rare disease that is difficult to diagnose and treat and is even rarer when it is caused by a lipoma of the small intestine. We reported a case of a small intestine lipoma combined with intussusception, which can guide people in future clinical work.

Case Presentation: A 51-year-old female was admitted to the hospital with "abdominal pain for 1 month.

A Rare Cause of Small Bowel Obstruction: A Case Report.

Introduction: Small bowel obstruction is a common surgical emergency abdominal condition in clinical practice. Fecalith is one of the rare causative factors, especially phytobezoars.

Case Report: We report the case of a 66-year-old man admitted with "abdominal pain with vomiting for 1 day.

Abdominal Cocoon With Intestinal Perforation: A Case Report.

Abdominal cocoon is a very rare abdominal disease. Abdominal cocoon mainly leads to intestinal obstruction, and abdominal cocoon with gastrointestinal perforation is rare. We report a 63-year-old man who was admitted to our hospital with "persistent lower abdominal pain for one day".

A case of iatrogenic intussusception in adults: a rare case report.

Background: Intussusception has a low incidence rate in adults. Many cases in adults are caused by tumors. Intussusception results from conditions other than tumors are uncommon.
