“…We had not performed SEMS in the present study period because Kim et al showed that SEMS was associated with peritoneal seeding after perforation [8]. However, it was shown that the technical success rates were 100% for SEMS and 78.9% for TDT and significantly greater resolution of histopathological edema was achieved after the placement of SEMSs than after the placement of TDTs [9]. No significant difference in postoperative mortality was reported between SEMS and TDT [2].…”

Colorectal cancer patients with malignant large-bowel obstruction (MLBO) require emergency treatment. Here we evaluated the long-term outcomes of recurrence and prognosis (not short-term mortality or nonocclusive cancer T1-T2) in colorectal cancer patients with and without an MLBO. Methods: We retrospectively analyzed the cases of the consecutive patients who underwent curative resection for colon cancer. We compared the groups regarding patients' age and gender, the tumor location, T and N factor, tumor stage, disease-free survival and overall survival. Results: The nonobstruction group had a significantly longer disease-free survival and overall survival compared with the MLBO group. Conclusion: MLBO was associated with cancer recurrence and poorer overall survival regardless of the staging and adjuvant chemotherapy.

“…However, a recent report stated that endoscopically placing a decompression device is helpful for subsequent elective laparoscopic colectomy and one‐stage anastomosis . Many studies have reported that SEMS placement is effective for decompression and can be a bridge to elective surgery, with reduced perioperative morbidity and mortality and a significantly increased success rate for one‐stage anastomosis . For LMCO, a longer duration of decompression leads to reduced edema and increased safety for one‐stage anastomosis .…”

A 78-year-old man with a history of open sigmoidectomy for sigmoid cancer presented with abdominal pain and vomiting. Abdominal multi-detector CT revealed an obstructive ileocecal tumor with distended small bowel on the oral side. We performed emergency drainage using a transnasal decompression tube, and 2 days later, we conducted a colonoscopic examination, which lead to a provisional diagnosis of obstruction with a malignant tumor invading the ileocecal valve. We then placed a self-expanding metallic stent (SEMS) through the ileocecal valve. We confirmed patency of the ileocecal valve and removed the transnasal decompression tube 2 days after SEMS placement. We then performed elective laparoscopic colectomy 8 days after SEMS placement. To the best of our knowledge, there has been only one previous report of laparoscopic colectomy after decompression with SEMS placement through the ileocecal valve for right-sided malignant colonic obstruction.

“…Histopathologically, the tumor was diagnosed as T4a, N0 (0/12), M0, stage IIB, according to UICC classification [3]. In addition, histopathological examination showed that the tumor was resected with negative resection margins (R0-resection) and revealed the absence of intestinal edema, on the basis of edema criteria, on the oral side [1] (Fig. 5a, b).…”

“…For malignant colorectal obstruction (MCO), preoperative decompression by placing a self-expanding metallic stent (SEMS) has been recognized as a safe and effective therapeutic strategy, and there is ample evidence for the feasibility of laparoscopic surgery after SEMS placement [1, 2]. However, no studies have reported robot-assisted laparoscopic surgery (RALS) after SEMS placement for malignant rectal obstruction (MRO).…”

BackgroundApproximately 20% of colorectal cancer patients show complete or incomplete bowel obstruction as an early symptom. Preoperative nonsurgical decompression such as placing a self-expanding metallic stent for malignant colorectal obstruction has been shown to be effective for reducing perioperative morbidity and mortality. However, there is a lack of published studies reporting robot-assisted laparoscopic surgery (RALS) after self-expanding metallic stent (SEMS) placement for malignant rectal obstruction (MRO). To our knowledge, this is the first report to do so.Case presentationAn 80-year-old man with incomplete paralysis of the lower limbs as well as bladder–rectal disorder due to a spine fracture sustained in a fall accident 26 years ago presented with lower abdominal pain and vomiting. Abdominal multi-detector computed tomography revealed an obstructive rectal tumor with distended bowel on the oral side. Emergency colonoscopy was performed, and an SEMS placed. The patency of SEMS and decompression of the distended bowel was confirmed, and elective RALS was performed 29 days after SEMS placement. To our knowledge, this is the first report of RALS after decompression with SEMS placement for MRO.ConclusionsRALS after SEMS placement is a safe and feasible therapeutic strategy for MRO.
