Abstract Background: laparoscopic segmental colectomy is suitable for removing difficult polyps that are large, broad-based, or located in tortuous bowel segments. As we know, accurate segmental resection depends on precise localization. So far, intraoperative labeling of lesions by colonoscopy is increasingly performed for achieving appropriate resection margins, but a certain deviation is also found. There is no unified and standard endoscopic polyp localization method at present.Case presentation: A 63-year-old woman was admitted because she was diagnosed as a large and broad-based colonic polyp which was unsuitable for colonoscopic polypectomy. During endoscopy-assisted laparoscopic segmental colectomy, the irradiation angle of colonoscopy light on the polyp head was responsible for the localization errors. We proposed three-step measures of correct endoscopic polyp localization to ensure the accurate resection in laparoscopic segmental colectomy.Conclusions: Three-step measures of correct endoscopic polyp localization ensured the successful resection of colonic polyps in laparoscopic colectomy. Their advantages include simplicity, practicality and reliable localization.

Inflammatory Polyposis

Abstract Giant inflammatory polyposis of the colon is an uncommon manifestation of inflammatory bowel disease. We report a unique case of localized diffuse giant inflammatory polyposis in a 58-year-old white man, which was characterized by recurrence following initial surgical resection. The patient presented with symptoms of abdominal pain and passing blood per rectum. Colonoscopic examination revealed a near-obstructing, “fungating” mass in the sigmoid colon, which clinically was thought to represent colon carcinoma. Histology of several colon biopsies revealed marked acute inflammation with microabscess formation of the polyps and the adjacent mucosa. There was no evidence of dysplasia or malignancy. Because malignancy was strongly suspected and to relieve the obstructive symptoms, the patient underwent a segmental colectomy. The histologic features of the resected mass showed giant polyps with acute inflammation diagnostic of giant inflammatory polyposis. Again, there was no evidence of malignancy. Seven months later, following an uneventful initial postoperative recovery, the patient developed a recurrence of the mass with obstructive symptoms and required further surgical resection. The gross and histologic features of the lesion were similar to the previous findings. This case highlights the varied presenting symptoms and deceptive gross colonoscopic and radiologic features of localized diffuse giant inflammatory polyposis. Finally, the presence of inflammation at the resection margins appears to predict recurrence or persistence of the disease.

Abstract Although simultaneous resection of primary colorectal cancer and synchronous liver metastases is reported to be safe and effective, the feasibility of a laparoscopic approach remains controversial. This study evaluated the safety, feasibility, and short-term outcomes of simultaneous laparoscopic surgery for primary colorectal cancer with synchronous liver metastases. From September 2008 to December 2013, 10 patients underwent simultaneous laparoscopic resection of primary colorectal cancer and synchronous liver metastases with curative intent at our institute. The median operative time was 452 minutes, and the median estimated blood loss was 245 mL. Median times to discharge from the hospital and adjuvant chemotherapy were 13.5 and 44 postoperative days, respectively. Negative resection margins were achieved in all cases, with no postoperative mortality or major morbidity. Simultaneous laparoscopic colectomy and hepatectomy for primary colorectal cancer with synchronous liver metastases appears feasible with low morbidity and favorable outcomes.

ObjectiveTo assess health-related quality of life in patients with non-dysplastic Barrett’s oesophagus (NDBO) and endoscopically treated dysplastic Barrett’s oesophagus (DBO).DesignThis quantitative, self-administered questionnaire study was conducted across three National Health Service hospitals. Data were collected from three other cohorts; gastro-oesophageal reflux disease (GORD), colonic polyp surveillance and healthy individuals. Fisher’s exact and Spearman’s rank correlation tests were used for analysis. Propensity score matching adjusted for age, sex and comorbidities.Results687 participants were eligible for analysis (NDBO n=306, DBO n=49, GORD n=132, colonic polyps n=152 and healthy n=48). 53% of NDBO participants reported similarly high cancer worry, comparable to DBO (50%, p=0.933) and colonic polyp participants (51%, p=0.355). Less cancer worry was reported in GORD participants (43.4%, p=0.01 vs NDBO). NDBO participants reported anxiety in 15.8% and depression in 8.6% of cases, which was similar to the other disease cohorts. Moderate or severe heartburn or acid regurgitation was found in 11% and 10%, respectively, in the NDBO cohort, comparable to DBO participants (heartburn 2% p=0.172, acid regurgitation 4% p=0.31) but lower (better) than GORD participants (heartburn 31% p=<0.001, acid regurgitation 25% p=0.001). NDBO participants with moderate or severe GORD symptoms were associated with higher rates of anxiety (p=<0.001), depression (p=<0.001) and cancer worry (p=<0.001). NDBO patients appropriately perceiving their cancer risk as low had lower rates of cancer worry (p=<0.001).ConclusionThis study provides insight into the problems Barrett’s oesophagus patients may face. Future care pathways must be more patient focussed to address misconceptions of cancer risk, oesophageal cancer related worry and GORD symptom control.

Colorectal cancer includes cancer of the colon, rectum, anus and appendix. Since it is largely preventable, it is extremely important to detect and treat the colorectal cancer in the earliest stage. Virtual colonoscopy is an emerging screening technique for colon cancer. One component of virtual colonoscopy, image preprocessing, is important for colonic polyp detection/diagnosis, feature extraction and classification. This chapter aims at an accurate and fast colon segmentation algorithm and a general variational-approach based framework for image pre-processing techniques, which include 3D colon isosurface generation and 3D centerline extraction for navigation. The proposed framework has been validated on 20 real CT Colonography (CTC) datasets. The average segmentation accuracy has achieved 96.06%, and it just takes about 5 minutes for a single CT scan of 512*512*440. All the 12 colonic polyps with sizes of 6 mm and above in the 20 clinical CTC datasets are found by this work.

Adenocarcinoma Of The Colon

Extensive squamous metaplasia in neoplastic colonic polyps is rare. This paper describes extensive squamous metaplasia in an adenomatous polyp evolving into adenocarcinoma. The origin of squamous cell carcinoma and adenocanthoma of the colon is not well understood. This case is the only case reported in the literature that demonstrates the development of squamous metaplasia in dysplastic colonic glands, in situ adenocarcinoma, and finally invasive adenocarcinoma of the colon. The pertinent literature is reviewed.
