In RY reconstruction using the OL, there were no complications associated with the anastomosis site in 100 consecutive patients, such as anastomotic leak or stenosis, indicating that it is a very useful and safe reconstruction method.
BACKGROUND:We aimed to clarify the utility of delta-shaped anastomosis (Delta), an intracorporeal Billroth-I anastomosis-based reconstruction technique used after laparoscopy-assisted distal gastrectomy (LADG), in robot-assisted distal gastrectomy (RADG).METHODS:RADG was performed in patients with clinical Stage I gastric cancer, and reconstruction was performed using Delta. The Delta procedure was the same as that performed after LADG, and the operator practiced the procedure in simulated settings with surgical assistants before the operation. After gastrectomy, the scope and robotic first arm were reinserted from separate ports on the right side of the patient. Then, a port on the left side of the abdomen was used as the assistant port from which a stapler was inserted, with the robotic arm in a coaxial mode. The surgical assistant performed functional end-to-end anastomosis of the remnant stomach and duodenal stump using a powered stapler.RESULTS:The mean anastomotic time in four patients who underwent Delta after RADG was 16.5 min. All patients were discharged on the post-operative day 7 without any post-operative complications or need for readmission.CONCLUSIONS:Pre-operative simulation, changes in ports for insertion of the scope and robotic first arm, continuation of the coaxial operation, and use of a powered stapler made Delta applicable for RADG. Delta can be considered as a useful reconstruction method.
Background Although 18F-fluorodeoxyglucose positron emission tomography (FDG-PET/CT) is now widely used in their differential diagnosis, it is sometimes difficult to distinguish between benign and malignant diseases. Case Presentation A 44-year-old woman was found to have abnormalities on health screening. Magnetic resonance imaging for detailed examination showed an intra-abdominal tumor measuring 12 cm in the major axis near the cranial end of the uterus. Upper gastrointestinal tract endoscopy showed a tumor with an ulcer in the third part of the duodenum, involving half the circumference. Heterogeneous uptake was observed within the tumor on FDG-PET/CT. Based on these findings, the patient underwent surgery for suspected primary malignant lymphoma of the duodenum or gastrointestinal stromal tumor. Laparotomy revealed a 12 cm tumor in the third part of the duodenum. Partial duodenectomy and end-to-end duodenojejunostomy were performed. Pathological findings showed a solid tumor growing from the muscle layer of the duodenum to outside the serous membrane; based on immunostaining, it was diagnosed as a leiomyoma. Conclusions Duodenal leiomyomas are originally benign; to date, there have been no reports of uptake in duodenal leiomyomas on FDG-PET/CT; therefore, our case is rare. Leiomyomas should be considered in the differential diagnosis of duodenal neoplastic diseases.
HighlightsA foramen of Winslow hernia is rare and difficult to diagnose.We report a post operative complication of foramen of Winslow herniation from left to right.There are no previous reports of a foramen of Winslow hernia with this presentation.It has been thought that closure of the foramen is not necessary.However, as there are no reports about the complications due to closing the Foramen of Winslow, the foramen should be closed, whenever possible.
Mesenteric neuroendocrine tumors are usually metastases originating from the small intestine; however, primary mesenteric cases are rare. We present an interesting case of a mesenteric neuroendocrine tumor that changed its internal composition from cystic to solid. A 72-year-old male visited our hospital because of epigastralgia 4 years earlier. A 25-mm tumor was recognized around the terminal duodenum on computed tomography and magnetic resonance imaging, and was diagnosed as a cystic lesion. Over the following 2 years, the tumor grew to 40 mm and its internal composition changed from cystic to solid. The lesion showed positive findings on fluorodeoxyglucose positron emission tomography. Upon laparotomy, a solid tumor was detected in the mesentery of the jejunum near the ligament of Treitz. The tumor was extracted without intestinal resection and was diagnosed as a low-grade neuroendocrine tumor after histopathological and immunohistochemical examination. One year has passed since the operation, and there has been no recurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
