Inverted appendix in a patient with colon cancer: a case report and long-term follow-up.

Appendiceal inversion is a rare entity that can potentially mimic serious pathology and provide diagnostic uncertainty. They are mostly diagnosed intraoperatively or during endoscopies and scans for other reasons. We report a case of an asymptomatic patient treated for colon cancer without previous history of appendectomy. We provide long-term follow-up and aim to review the relevant literature.

Solitary fibrous tumour of the gallbladder: A rare case report.

INTRODUCTION AND IMPORTANCE: Solitary fibrous tumours are rare mesenchymal neoplasms with limited malignant potential that can occur anywhere in the body, with a predilection towards body cavities such as the pleura. It has been reported to arise in the peritoneum and the mesentery. CASE PRESENTATION: This is a case of a female patient who presented with an incidental abdominal mass compressing the duodenum. Differential diagnosis included GIST and intra-operatively was found to be arising from the gallbladder. En-bloc cholecystectomy was done and diagnosed a solitary fibrous tumour. CLINICAL DISCUSSION: This is the second case of gallbladder solitary fibrous tumour reported in the literature. CONCLUSION: Awareness of this rare entity is important for diagnosis and treatment.

State of the art in robotic rectal surgery: marginal gains worth the pain?

After their first introduction in the 1990s to overcome the limitations of conventional laparoscopic surgery, especially in confined spaces such as the pelvis, telemanipulators (i.e., master-slave manipulators) have gained popularity and acceptance among gastrointestinal surgeons. These complex, interventional surgical devices use multiple technologies, such as 3-D advanced imaging, tremor reduction and 7-degree movement. Superior instrument dexterity, stable precise vision and accessibility to narrow confined spaces make these devices well suited for colorectal surgery. The drive for innovations in the field of surgical robotics will leverage novel robots driven by data, image integration, and artificial intelligence. However, if this vision is to be realized, lessons must be learned from the current literature and clinical trials. The feasibility and safety of robotic rectal surgery is now well established; increasing evidence suggests that when compared to laparoscopic rectal surgery, robotic approaches might offer superior peri-operative outcomes. Notably, the marginal gains achieved with the use of robotics in rectal cancer surgery are linked with structured training and standardization of operative techniques. With decreasing costs and wider availability of new systems, it is foreseeable that robotic surgical systems will be an integral part of colorectal practice.
