A case of diaphragmatic hernia incarceration after a heart transplant operation

We report a case of a diaphragmatic hernia after a heart transplant operation. A 43-year-old woman, who underwent orthotropic heart transplantation for hypertrophic cadiomyopathy two year earlier, presented with vomiting and epigastric pain. A computed tomography scan showed that the stomach and transverse colon were dislocated in the left thoracic cavity. We diagnosed left diaphragmatic hernia incarceration and performed laparoscopic repair of the diaphragmatic hernia. A 12 × 8 cm diaphragmatic defect was found intraoperatively on the ventrolateral aspect of the left diaphragm, and the stomach with volvulus had herniated into the thorax through the defect. The hernia was considered to be iatrogenic. The diaphragmatic defect was large, and the diaphragm was thinning. We closed the defect by mesh repair. Laparoscopic mesh repair of the diaphragmatic hernia could be performed safely and with minimal invasiveness.     

Laparoscopic surgery for familial multiple gastrointestinal stromal tumors with germ line c-kit gene mutation

Familial gastrointestinal stromal tumor (GIST) is an exceedingly rare disease characterized by mutations in the c-kit and platelet-derived growth factor receptor alpha genes. We report the case of a 73-year-old woman with multiple submucosal tumors (SMTs) in the stomach and small intestine. Her elder sister had previously presented with multiple SMTs on examination and underwent surgery to remove the tumors because they showed a tendency to increase in size during follow-up. The sister's tumors were pathologically diagnosed as GISTs, and a germ line mutation was recognized in exon 17 of c-kit. Subsequently, the patient presented with multiple SMTs and the same germ line mutation as her sister. After 9 years of follow-up, a single tumor was found to have grown in size, and SILS was performed for this SMT, which was also pathologically diagnosed as a GIST. To our knowledge, this is the first report of laparoscopic surgery for a case of familial GIST.
