“…Laser energy can be applied as endoscopic laser therapy in stenosing primary colorectal tumors or as LITT in liver metastases, whereas, laser recanalization of malignant intestinal stenoses is a palliative treatment and purely experimental at present, especially with regard to the risk of intestinal perforations [7]. A basic problem of thermal laser application is the lack of appropriate treatment monitoring during the intervention [8,9].…”

“…Thus, almost half of all patients with colorectal carcinomas can no longer be considered for curative therapy at the time of diagnosis, which necessitates the development of alternatives to surgery. Local therapeutic application of laser light is considered promising, since it can be used for local ablation of colorectal primary tumors and for laser-induced thermotherapy (LITT) of liver metastases, whereas, laser recanalization of malignant intestinal stenoses is a palliative treatment and purely experimental at present, especially, with regard to the risk of intestinal perforations [7]. One problem with all thermal laser applications is the lack of suitable online monitoring procedures during the intervention [8,9].…”

Colorectal tumors and hepatic metastases differ in their optical properties—relevance for dosimetry in laser-induced interstitial thermotherapy

et al. 2006

Colon carcinoma tissue has a higher optical penetration depth than healthy colon tissue, which speaks in favor of tumor selectivity for interstitial laser application, since large treatment volumes can be obtained in the tumor. The lack of agreement between primary tumors and their concomitant liver metastases indicates a modification of optical behavior through metastasis. Thermal coagulation of tissue leads to changes in the optical properties, which are clearly less pronounced in carcinoma tissue. The data obtained in this study clearly show that an individual irradiation schedule is necessary for effective and safe dosimetry in laser-induced thermotherapy (LITT).

“…Treatment strategies as an alternative for palliative surgery for advanced stage rectal cancer include laser ablation, argon plasma coagulation, electrocoagulation, photodynamic therapy, pelvic radiotherapy, chemotherapy, endoscopic stenting, and cryotherapy 7-11. Treatment selection should consider the patient’s symptoms, age, comorbid conditions, extent of disease, and patient preference.…”

Large Bowel Obstruction following Endoscopic Spray Cryotherapy for Palliation of Rectal Cancer Bleeding

We report a unique case of a 79-year-old woman with metastatic rectal cancer who developed bowel obstruction following endoscopic cryotherapy with liquid nitrogen for palliation of bleeding in the rectum. She developed abdominal distention and pain following the procedure. Computed tomography of the abdomen revealed a paraumbilical hernia containing a segment of transverse colon resulting in partial bowel obstruction. It appears that the recurrent freeze-thaw cycles with poor decompression of the colon despite active venting suction during cryotherapy may have resulted in bowel distention and collapse, causing conformational changes resulting in partial bowel obstruction due to a paraumbilical hernia.

“…Rao et al79 reported 11 patients who were offered palliation with endoscopic Nd-YAG laser ablation for rectal carcinoma ( n =8), rectosigmoid tumor ( n =2), and recurrent tubulovillous adenoma ( n =1). The number of treatment episodes varied from 1 to 12, and the symptom-free interval was 2 to 18 months between treatment episodes.…”

Recently, placement of self-expandable metallic stents has been used for the treatment of colorectal obstruction. As domestic awareness of colorectal cancer has increased, the number of colorectal stenting procedures performed has also increased. We aimed to provide evidence-based recommendations for colorectal stenting to aid gastroenterologists in making informed decisions regarding the management of patients who present with colorectal obstruction. The working group consisted of eight gastroenterologists who actively practice and conduct research in the field of colorectal stenting and are the members of the Stent Study Group of the Korean Society of Gastrointestinal Endoscopy. A literature search was conducted using the PubMed, Embase, KoreaMed, and the Cochrane Library databases to identify relevant articles published between January 2001 and June 2012. Based on the modified Delphi process, 10 recommendation statements regarding indications, usefulness, methodology and complications of colorectal stenting, and alternative treatments for malignant colorectal obstruction were determined. The contents will be widely distributed, and periodically revised to reflect the latest knowledge. These evidence-based recommendations for colorectal stenting will provide gastroenterologists and patients with appropriate and balanced information, and will improve the quality of care.

Endoscopic laser ablation of advanced rectal carcinoma – a DGH experience

Abstract: Endoscopic laser ablation is a practical and feasible alternative to other palliative treatment modalities in the management of this unfortunate category of patients due to low morbidity and mortality, short hospitalization and low complication rates.
