We herein report the first case of rectal stenosis that developed after internal hemorrhoid treatment with aluminum potassium sulfate and tannic acid (ALTA) therapy that was successfully treated by laparoscopic surgery. A 72‐year‐old man suffered from a fever and rectal stenosis after undergoing internal hemorrhoid treatment with a submucosal injection of ALTA at a previous clinic. Three months after ALTA therapy, he developed frequent mucous and bloody stools. Lower intestinal tract endoscopy revealed circumferential severe rectal stenosis. He was therefore referred to our hospital. The patient suffered from frequent stool build‐up and difficulty defecating. We performed balloon‐dilatation intervention. The stenosis was not improved at all. Five months after ALTA therapy, we performed laparoscopic low anterior resection with diverting ileostomy. Three months after the operation, ileostomy takedown was performed. The patient has experienced no rectal stenosis in the 2 years since his radical operation. [ABSTRACT FROM AUTHOR]

Purpose: The number of elderly patients with colorectal cancer (CRC) treated with surgery has gradually increased. The aim of this study was to evaluate the short-term outcomes in patients ≥80 years of age who underwent laparoscopic or open surgery for CRC using a propensity score-matched analysis to make uniform the patient background characteristics affecting the postoperative morbidity and mortality.Methods: We compared the short-term outcomes of open vs. laparoscopic surgery in patients with CRC ≥80 years of age between 2010 and 2015. Fifty-two patients undergoing laparoscopic colectomy for CRC were matched to 52 patients undergoing open colectomy with respect to gender, age, body mass index, performance status, prognostic nutritional index, Charlson Comorbidity Index score, tumor-node-metastasis stage, and tumor location. The operative time, blood loss, length of hospital stay, and postoperative complications were investigated.Results: Blood loss was less during laparoscopic surgery than during open surgery (40 vs. 140 ml, p < 0.001). In the laparoscopic surgery group, the hospital stay was shorter (11 vs. 14 days, p < 0.001) and the morbidity rate lower (21.2 vs. 40.4%) than in the open surgery group. The mortality for both groups was similar (0 vs. 1.9% for laparoscopic surgery vs. open surgery).Conclusion: Laparoscopic surgery in octogenarians with CRC is a safe, low-invasive alternative to open surgery with less blood loss and a shorter hospital stay.

A 56-year-old woman with complaints of anal bleeding and pain visited our hospital, and an elastic soft mass was detected in the anal canal on digital examination.Colonoscopy showed a black Isp polypoid lesion with a black pit from the anal canal to the lower rectum(P-Rb).She was diagnosed with malignant melanoma based on colonoscopic biopsy.Tumor marker levels(CEA, CA19-9)were not increased.No distant metastasis was detected on abdominal CT.No direct invasion was detected on MRI of the pelvis.The patient underwent laparoscopic abdominoperineal resection and D2 lymph node dissection. Histopathology showed a malignant melanoma(pT4b, N0, M0, pStageⅡC).The patient received interferon therapy as adjuvant therapy.There is no sign of recurrence 2 years and 1 month after the surgery.Anorectal malignant melanoma is relatively rare, so establishment of therapy by the accumulation of cases is desired.

Anal metastasis of colorectal cancer is rare, and no standardized effective therapeutic strategy exists. We report a case of abdominoperineal resection for anal metastasis of rectal cancer. A 65-year-old man underwent laparoscopic low anterior resection for rectal cancer in August 2013. Histopathological examination revealed a moderately differentiated adenocarcinoma( tub2, pSS, ly3, v2, pN1, H0, P0, M0, Stage III a, Cur A). In February 2015, he complained of anal discomfort, and tumor markers were elevated. Enhanced CT revealed a 15-mm high-density solid tumor in the anal canal. The results of needle biopsy indicated a moderately differentiated adenocarcinoma. This tumor was suspected to be metastasis from rectal cancer, and we performed abdominoperineal resection. Histopathological examination revealed a moderately differentiated adenocarcinoma, which was the same histological type as the primary rectal cancer and was covered with normal anal epithelium. Collectively, the findings indicated anal metastasis from rectal cancer. The patient is alive without recurrence for 18 months after resection. Anal metastasis should be considered as a differential diagnosis in patients with anal discomfort who have a history of colon/rectal cancer. Abdominoperineal resection may be an effective treatment modality for this condition.
