Laparoscopic surgery for obstructive colorectal carcinoma is a controversial issue. Defining the obstructive carcinoma as colonoscopic impassability, the patients with obstructive carcinoma were managed according to the treatment algorithm, by which the indication of open or laparoscopic surgery was determined. As a result, 31 patients with obstructive colorectal carcinoma underwent laparoscopic surgery. The location of the tumor was in the right side in 10 patients and in the left in 21 patients. Preoperatively, all cases were managed by restriction of oral intake and/or decompression. Laparoscopic surgery was completed in 26 cases and colonic obstruction was the direct cause of the conversion in only 1 case. Regarding postoperative complications, there were 3 surgical site infections and 3 instances of postoperative prolonged ileus but no mortality. Oncologically, the primary tumor was completely resected in each case and lymph node harvest (26.6) was adequate.

“…Synchronous malignancies most commonly occur in the colon, with a particularly high prevalence in elderly patients (1,2). The occurrence of synchronous colorectal cancers is extremely rare and may be identified at any location within the large intestine (3). Synchronous cancers are relatively uncommon, and triple synchronous colon cancers are particularly rare.…”

Abstract. Synchronous colorectal cancers refer to the simultaneous occurrence of multiple colorectal tumors in a single patient, excluding any metastases from other organs. At present, radical surgery is considered the standard curative treatment; however, individualized surgical strategies depend on tumor location, the depth of invasion and the general health of the patient. In the present study, the case of a 52-year-old man who presented with a 2-month history of abdominal pain that was accompanied by intermittent hematochezia and weight loss is reported. The patient had no family history of cancer. Computed tomography (CT) of the abdomen revealed intestinal wall thickness in the transverse colon and volvulus in the hepatic flexure of colon. Colonoscopy identified 3 tumors: The first tumor was located in the descending colon with lumen stenosis ~60 cm from the anal verge, the second tumor was located in the hepatic flexure of the colon, and the third tumor was located in the sigmoid colon, 23 cm from the anal verge. Subsequently, laparoscopic subtotal colectomy was performed and all three tumors were removed, and the diagnosis was confirmed by histopathological examination. The patient did not undergo chemotherapy following surgery, due to personal reasons. Subsequent to 19 months of follow-up examinations using CT and colonoscopy every 6 months, the patient exhibited no signs of recurrence. Thus, laparoscopic subtotal colectomy represents an effective surgical approach for the treatment of synchronous colorectal cancer following imaging and endoscopic diagnosis.

“…For low prevalence of SCRC, there is no common consensus on its operative strategies and extents of resection [34]. Moreover, one of the disadvantages of laparoscopic approach is its lack of tactile sensation, the limitation of visualization and some small inconspicuous lesions in the abdominal cavity or bowel may sometimes be overlooked.…”

The primary aim of this study was to explore the safety and feasibility of laparoscopic-assisted synchronous bowel anastomoses (LSBA) for synchronous colorectal cancer (SCRC). All patients who underwent LSBA for SCRC were retrospectively reviewed and analyzed for clinical and pathological features, technical feasibility and short-term as well as long-term oncological outcomes. Between July 2008 and January 2012, a series of 11 consecutive SCRC patients underwent LSBA. Six patients underwent laparoscopic-assisted right hemicolectomy and anterior resection. Five patients had laparoscopic-assisted right hemicolectomy and sigmoidectomy. There were no intraoperative complications that required open conversions. Mean operation time was 233 (range, 195–285) minutes, and mean estimated blood loss was 224 (range, 100–300) mL. The postoperative course of the patients was uneventful with the mean return to oral intake was 6.9 (range 5–12) days, and mean length of hospital stay was 12.6 (range 9–17) days. All surgical wounds showed good cosmetic outcome, and the mean incision length was 4.1 (range 3.5-5.0) cm. During a median follow-up period of 76 months, no local tumor recurrences were found. LSBA is a potentially feasible and safe procedure for SCRC when performed by an experienced surgeon. Further large clinical controlled trials are warranted to confirm the findings.
