Conjoined twins are a rare occurrence, and the majority of these malformations are detected during second trimester screening.

Herein we report a case of conjoined twins, which was diagnosed by ultrasound at 8 wk gestation and was normal at 7 wk gestation. The two fetuses shared one heart and were diagnosed as thoracopagus twins. This is the first report of conjoined twins diagnosed at 8 wk gestation. The pregnancy was terminated electively at 9 wk gestation. Because some congenital malformations can be diagnosed earlier, a prenatal ultrasound examination at an early gestational stage cannot be dismissed.

This case demonstrates that a 7-8 wk gestation might be the earliest period when conjoined twins can be diagnosed by ultrasound.

Pancreatic cancer with ovarian metastases is rare and easily misdiagnosed. Most patients are first diagnosed with ovarian cancer. We report a rare case of ovarian metastases secondary to pancreatic adenocarcinoma. We also review the literature to analyze the clinical characteristics of, diagnostic methods for, and perioperative management strategies for this rare malignancy.

A 48-year-old woman with an abdominal mass presented to our hospital. Computed tomography revealed lesions in the pancreas and lower abdomen. Radiological examination and histological investigation of biopsy specimens revealed either an ovarian metastasis from a pancreatic neoplasm or two primary tumors, with metastasis strongly suspected. The patient simultaneously underwent distal pancreatectomy plus splenectomy by a general surgeon and salpingo-oophorectomy with hysterectomy by a gynecologist. Histological examination of the surgical specimen revealed a pancreatic adenocarcinoma (intermediate differentiation, mucinous) and a metastatic mucinous adenocarci-noma in the ovary.

For this rare tumor, surgical resection is the most effective treatment, and the final diagnosis depends on tumor pathology.

Palatal expansion treatment has been used to expand the constricted maxillary arch and has become a routine procedure in orthodontic practice over the past decades. However, the long-term stability of expansion in the permanent dentition without a surgical approach is uncertain.

We present the case of a 15-year-old boy with Class II malocclusion and constricted arches. The patient was treated with rapid palatal expansion (RPE) followed by a fixed orthodontic appliance. A 7-year follow-up evaluation was performed by analyzing cephalometric radiographs, plaster models, and photographs. The patient's constricted maxillary and mandibular arches were relived after the expansion treatment. A Class I occlusion and normal arch form were established and maintained in the long-term.

RPE treatment is successful in solving constricted dental arch in the permanent dentition without a surgical approach. Permanent retention and even occlusal contact help prevent long-term relapse.

Severe acute respiratory syndrome coronavirus 2 has been confirmed to be a newly discovered zoonotic pathogen that causes highly contagious viral pneumonia, which the World Health Organization has named novel coronavirus pneumonia. Since its outbreak, it has become a global pandemic. During the outbreak of coronavirus disease 2019 (COVID-19), however, there is no mature experience or guidance on how to carry out emergency surgery for suspected cases requiring emergency surgical intervention and perioperative safety protection against virus.

A 41-year-old man was admitted to the hospital for emergency treatment due to "3-d abdominal pain aggravated with cessation of exhaust and defecation". Tovorafenib After improving inspections and laboratory tests, the patient was assessed and diagnosed by the multiple discipline team as "strangulation obstruction, pulmonary infection". His body temperature was 38.8 °C, and the chest computed tomography showed pulmonary infection. Given fever and pneumonia, we could not rule out COtracted the perioperative protection experience. By referring to the literature and following the regulations on prevention and management of infectious diseases, we have developed a relatively mature and complete emergency surgical workflow for suspected COVID-19 cases and shared perioperative protection and management experience and measures.

Based on the previous treatment experience, we reviewed the procedures of two cases of suspected COVID-19 emergency surgery and extracted the perioperative protection experience. By referring to the literature and following the regulations on prevention and management of infectious diseases, we have developed a relatively mature and complete emergency surgical workflow for suspected COVID-19 cases and shared perioperative protection and management experience and measures.

Afferent loop syndrome (ALS) is a rare mechanical complication that occurs after reconstruction of the stomach or esophagus to the jejunum, such as Billroth II gastrojejunostomy, Roux-en-Y gastrojejunostomy, or Roux-en-Y esophagoje-junostomy. Traditionally, an operation is the first choice for benign causes. However, for patients in poor physical condition who experience ALS soon after R0 resection, the type of treatment remains controversial. Here, we present an efficient conservative method to treat ALS.

Case 1 was a 69-year-old male patient who underwent total gastrectomy with Roux-en-Y jejunojejunostomy. On postoperative day (POD) 10 he developed symptoms of ALS that persisted and increased over 1 wk. Case 2 was a 59-year-old male patient who underwent distal gastrectomy with Billroth II gastrojejunostomy. On postoperative day POD 9 he developed symptoms of ALS that persisted for 2 wk. Both patients underwent fluoroscopic-guided nasointestinal tube placement with maintenance of continuous negative pressure suction.
