We reported a case of irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.The patient complained about a right groin mass for more than 60 years with progressive enlargement for 3 years and pain for half a month.Abdominal CT examination at admission showed rectum and sigmoid colon hernia in the right inguinal area and thickening of sigmoid colon wall.Electronic colonoscopy and pathological diagnosis showed sigmoid colon cancer.Therefore,the result of preliminary diagnosis was irreducible indirect inguinal hernia caused by sigmoid colon cancer entering the right groin.We converted laparoscopic exploration to laparotomy followed by radical sigmoidectomy and employed end-to-end anastomosis of descending colon and rectum in combination with repair of right inguinal hernia.The patient recovered well after operation and was discharged.

PURPOSE: The Oral-anal Transit Test (OTT) is a simple method of obtaining information about colonic transit. We aim to assess the correlation of OTT with the neuromuscular integrity of the colon determined by colonic manometry (CM).METHODS: All patients who had OTT followed by CM were evaluated. Less than 6 of 24 markers remaining on OTT was considered normal. CM was performed per previously published guidelines. A normal CM was defined as at least one High Amplitude Propagating Contraction progressing from the most proximal sensor through the sigmoid colon.RESULTS: A total of 34 patients underwent both OTT and CM (44% male, age 4–18 years, mean 11.5 years, 97% functional constipation +/− soiling, Hirschsprung's Disease). Of normal and abnormal OTT patients, 85.7% (6/7) and 18.5% (5/27) respectively had normal CM. When all markers progressed to at least the sigmoid colon, this was 100% predictive against colonic inertia. Greater than 50% of patients with manometric isolated sigmoid dysfunction had markers proximal to the recto-sigmoid.CONCLUSION: OTT and CM are both valuable studies that assess different aspects of colonic function. OTT can be used as a screening test to rule out colonic inertia. However, the most proximal extent of remaining markers does not predict the anatomical extent of the manometric abnormality, particularly in isolated sigmoid dysfunction.

sigmoid colon and anterior to the bifurcation of left common iliac vessel. It was supplied by numerous aberrant vessels from the terminal part of abdominal aorta. One of the renal veins which drain the ectopic kidney was found to be persisting subcardinal vein and it is a novel finding. Such ectopic pelvic kidneys are susceptible to blunt trauma, iatrogenic injuries as well as pathologic manifestations.]]>

The pneumatic colorectal injury caused by high pressure compressed air are rare and can be fatal. Herein, we present a case of 45-year-old male who developed sudden onset of severe abdominal pain after cleaning the dust on his pants with high pressure compressed air gun dust cleaner. Emergent exploratory laparotomy was done which findings are a huge rectal perforation with multiple serosal and subserosal tear in sigmoid to splenic flexure of colon. Anterior resection with left hemicolectomy, and temporary transverse colostomy was performed. Postoperative course was uneventful. Recently, prognosis is generally favorable because of prompt diagnosis and emergent surgical management.

Primary malignant melanoma (PMM) of the gastrointestinal tract is rare. Reported cases of PMM of the lower gastrointestinal tract typically describe anal and rectal involvement rather than colonic lesions. This report describes a rare case of a 50-year-old woman with PMM originating in the colon. The patient presented to Inje University Busan Paik Hospital with a 3-day history of blood-tinged stools. She underwent colonoscopy for a diagnosis of hematochezia. The colonoscopic examination revealed a large-sized semi-pedunculated sigmoid colon polyp with a reddish-colored mucosal surface. Endoscopic mucosal resection was performed, and the final histopathological findings were consistent with a diagnosis of malignant melanoma. Systemic work-up was performed for assessment of metastasis and to identify the primary tumor considering the high metastatic rate of gastrointestinal malignant melanoma; however, no other malignant lesion was detected. Thus, she was diagnosed with colonic PMM. She underwent laparoscopic low anterior resection and lymph node dissection and has been recurrence-free for > 2 years.

PURPOSE: Bevacizumab has been used as a promising drug for metastatic colorectal cancer in combination with chemotherapeutic agents. However, it has a few serious adverse effects, such as intestinal bleeding or perforation. The purpose of this study is to identify the clinical characteristics of intestinal perforation induced by bevacizumab in colorectal cancer patients.METHODS: From January 2007 to June 2018, a total of 488 patients underwent chemotherapy with bevacizumab for metastatic colorectal cancer. Medical records were reviewed retrospectively.RESULTS: Nine patients (1.8%) were identified with intestinal perforation induced with bevacizumab. The median age was 59 years (range, 36–68 years). The primary tumor site was the sigmoid colon in six patients, the rectum in three patients. The liver was the most common metastatic organ (7 patients). Perforation sites were primary tumor site of the colorectum in four patients and the small bowel in five patients. Intestinal perforation was developed after a median of 3 chemotherapy cycles (range, 1–15 cycles), and a median of 7 days (range, 3–32 days) after chemotherapy. One patient expired due to sepsis.CONCLUSION: Bevacizumab induced intestinal perforation is a lethal adverse effect in patients with colorectal cancers. The characteristics of intestinal perforation varied according to perforation site, previous chemotherapy cycles, and clinical course. Careful monitoring is necessary with the use of bevacizumab in conjunction with chemotherapeutic agents.
