Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur.

Defecatory disorders are very common complications after left hemicolectomy and anterior rectal resection. These disorders seem related primarily to colonic denervation after the resection. To evaluate the real benefits of inferior mesenteric artery (IMA) preservation via laparoscopic left hemicolectomy performed for diverticular disease in terms of reduced colonic denervation and improved postoperative intestinal functions, a randomized, single-blinded (patients) controlled clinical trial was conducted.

Ulcerative colitis (UC) can be treated with surgery or medications. Patients often must choose between long-term immunosuppressant therapy or total colectomy. Whether one of these treatment approaches has a mortality benefit is uncertain.

Although the feasibility and safety of laparoscopic surgery for transverse colon cancer have been shown by the recent studies, the optimal laparoscopic approach for mid-transverse colon cancer is controversial.

Previous studies have raised concerns that the use of anti-TNF therapy in patients with ulcerative colitis (UC) undergoing surgery may increase the risk of post-operative complications. We have taken a population-based approach to investigate whether there is an association between anti-TNF therapy and post-operative complications in UC patients undergoing subtotal colectomy.

Here, we report on the feasibility of ICG fluorescence imaging to localize lesions in emergent minimally invasive surgery. A 49-year old female presented to the emergency department with a previously unknown malignant bowel obstruction. She was taken emergently to the operating room for a laparoscopic extended right hemicolectomy, based on tumor location from imaging. With intraoperative difficulty localizing the lesion, an on-table colonoscopy was performed. When the tumor was encountered, peritumoral ICG injections were performed, and the fluorescence lymphoscintigraphy was performed intraoperatively in an attempt to visualize the primary tumor laparoscopically. Intraoperative ICG Immunofluorescence allowed precise, real-time localization of the mass in the descending colon. This information changed the course of the operation, as a laparoscopic left hemicolectomy was then performed instead of the planned extended right hemicolectomy. The patient underwent an end-to-end anastomosis without the need for a defunctioning ileostomy. From this case, we demonstrate the use of ICG fluorescence imaging for tumor localization in the emergent setting is safe, feasible, and effective. This information gained from this technology enables real-time decision making, and can even change the operative plan in the emergent setting for the best patient outcomes. What does this paper add to the existing literature? This paper offers a novel application of an emerging technology- ICG fluorescence- that in this capacity allowed precise, real-time localization of a previously unknown mass in the emergent setting, and changed the course of the operation.

There is a clear consensus regarding the combined resection of organs with cancer invasion, patients with colon cancer. However, there are very few reports to our knowledge regarding the use of pancreato-duodenectomy(PD)for colon cancer patients with cancer invasion in the duodenum. We here report a colon cancer patient in whom we performed PD and right hemicolectomy, who showed favorable results with no recurrence. The patient was a 69-year-old woman. Her chief complaint was hypogastric pain. Her previous doctor performed colonoscopy and a colonoscopic biopsy, and detected a type 2 lesion, throughout the entire circumference of the transverse colon near the liver, and she was diagnosed with adenocarcinoma. From further imaging analyses, she was diagnosed as having transverse colon cancer with invasion into the superior mesenteric vein(SMV), duodenum, and pancreatic head, and No. 223 lymph node metastasis. The patient’s cancer was concluded to be unresectable, and she underwent chemotherapy, namely mFOLFOX6 with cetuxiumab(Cmab). One course of mFOLFOX with Cmab, the patient decided to consult our hospital for a second opinion. We concluded that her cancer was resectable, so we performed PD, right hemicolectomy, and resection and reconstruction of a part of the SMV. The operation time was 5 hours 17 minutes, and total blood loss was 190 mL. The histopathological diagnosis was tub2, T4b(duodenum and, tissue surrounding the SMV), int, INF b, ly1, v2, PN1b, EX(+)/ND(PN+, v+), PM0(25 cm), DM0(14.3 cm), N1(1/ 20), H0, P0, M0, pStage III a. She was discharged 15 days after surgery with no complications, and thereafter received ajduvant chemotherapy(capecitabine with oxaliplatin)as an outpatient. After 3 courses, capecitabine with oxaliplatin was changed to capecitabine because she developed a nervous system disorder, and she was further treated for approximately about 6 months. She is doing well at the time of writing, with no recurrences for 2 years. We suggest that PD should be performed on colon cancer patients in which the colon cancer has invaded other organs and has been evaluated as being unresectable.
