Introduction of multimodality treatment as the standard of care for management of esophageal and gastroesophageal junction (GEJ) cancer over the last years has led to significant improvement in survival for patients with localized disease. Nevertheless, treatment with curative intent is not considered in the case of metastatic disease. We report a case of a locally advanced GEJ adenocarcinoma with solitary resectable synchronous metastases at the jejunum and a good response to neoadjuvant therapy followed by esophagectomy with curative intention.

This is the case of a patient with poorly differentiated adenocarcinoma of the GEJ with synchronous metastases at the jejunum. The patient underwent extensive work-up including PET-CT. The metastases at the jejunum were completely resected during an initial staging laparoscopy and there was no evidence of further metastatic disease. The patient received chemotherapy and re-staging showed remarkable tumor response. Esophagectomy with curative intent was performed.onsidered for treatment with potentially curative intent.
In this case report from Muhimbili National Hospital, Dar es salaam, Tanzania, we present the unexpected findings of anorectal malformation, colonic atresia, and intestinal malrotation in a 2-day old neonate. This combination is exceedingly rare, with only case reports published in the literature. We describe the challenges in diagnosis and offer our insights based on this experience and review of the literature.

Our patient was a male born at term, weighing 2600g, diagnosed clinically with a high anorectal malformation. He was planned for colostomy, and we unexpectedly found a collapsed descending colon. Exploration revealed intestinal malrotation and three segments of type I colonic atresia from the mid transverse colon to the sigmoid colon in addition to the high anorectal malformation.

Creating a colostomy in a high anorectal malformation and failure to identify proximal intestinal atresia would result in potentially devastating consequences. Colonic atresia and anorectal malformation will both present as large bowel obstruction. In the extremely rare situation, when occurring in combination, the obvious clinical diagnosis of anorectal malformation will mask the clinical suspicion of the possibility of colonic atresia. Finding a distal bowel air bubble above the pubococcygeal line on an invertogram is useful in identifying proximal atresia preoperatively.

The current report emphasizes the importance of maintaining an awareness of possible associated colonic atresia in neonates with anorectal malformation. An invertogram and intraoperative finding of a collapsed descending colon should prompt evaluation for a proximal obstructing lesion.

Appendiceal adenocarcinomas, although rare, usually present as slow-growing masses. Rarely, do they rapidly enlarge into large abdominal masses over a short period of time. Generally, we attribute rapidly growing abdominal masses to sarcomas, desmoid tumors, or gynecological masses. We present a case of a rapidly growing appendiceal adenocarcinoma in an elderly patient.

We report a case of an 83-year-old-male who presented with a one-month history of abdominal pain. A computer tomography (CT) scan identified a lower pelvic mass measuring 7.39cm×5.40cm. A biopsy was done which revealed appendiceal carcinoma. A plan for radiotherapy to reduce the tumor size was made and the patient was discharged. However, the patient returned after three weeks due to worsening abdominal pain and a CT scan identified a significant enhancement in the tumor size. The patient underwent debulking surgery. Pathology of the specimen identified adenocarcinoma of the appendix.

A rapidly growing carcinoma of the appendix is rare as they are known to have a slow growth rate. A swift diagnosis and intervention are required as these rapidly enhancing neoplasms in the abdomen can become unresectable and metastasize. Although there are various methods of treatment for appendiceal carcinomas, the rapid growth rate and lack of response to radiation required debulking surgery.

There exist a myriad of differential diagnoses for a rapidly growing mass in the abdomen. We are presenting the first documented case of a rapidly growing appendiceal adenocarcinoma. KYA1797K Surgeons should be aware of the variety of differentials in such cases.

Nevertheless, 3D printing of silicone has been challenging and the recent advances in technology are provided by the systems which can print medical grade silicone via extrusion. However, the potential impacts of the 3D printing process of silicone on its biomechanical properties has not been studied in sufficient detail. Therefore, the present study compares 3D printed and moulded silicone structures for their cytotoxicity, surface roughness, biomechanical properties, and in vivo tissue reaction. The 3D printing process creates increased nanoscale roughness and noticeably changes microscale topography. Neither the presence of these features nor the differences in processes were found to result in an increase in cytotoxicity or tissue reaction for 3D printed structures, exhibiting limited inflammatory reaction and cell viability above the threshold values. On the contrary, the biomechanical properties have demonstrated significant differences in static and dynamic conditions, and in thermal expansion. Our results demonstrate that 3D printing can be used for establishing a better biomechanical microenvironment for the surrounding tissue of the implant particularly for fragile soft tissue like epithelial mucosa without having any negative effect on the cytotoxicity or in vivo reaction to silicone. For engineering of the implants, however, one must consider the differences in mechanical properties to result in correct and personalized geometry and proper physical interaction with tissues.
