Efficacy Comparison and Safety Analysis of Radical Resection of Sigmoid Colon Cancer Based on Different Cancer Locations

Background: Sigmoid colon cancer is a common type of colon cancer; it refers to tumor lesions occurring in the segment approximately 16 cm to 50 cm from the anal margin. Currently, surgical resection is the most effective treatment for non-metastatic sigmoid colon cancer. Therefore, to more accurately standardize colon cancer surgery, we classified the sigmoid colon into distal and proximal segments. This study compares and analyzes the intraoperative situation, postoperative pathology and safety of radical resection of sigmoid cancer in different locations from different aspects. Result: The patients with sigmoid colon tumor can be divided into distal group (16-30cm from the anus) and proximal group (31-50cm from the anus) according to the distance between the tumor and the anal margin. Conclusion: The patients in the distal group using stapler for intestinal anastomosis and anal decompression tube were significantly more than those in the proximal group. For the ligation of the inferior mesenteric artery, high ligation was usually used or the left colic artery was usually preserved in the distal group, and the superior rectal artery was usually retained in the proximal group. The incidence of postoperative complications in the distal group was higher than that in the proximal group, but there was no significant difference between the two groups.

Insertion of Transnasal Abscess Drainage Tube, Decompression Tube, and Jejunal Nutrition Tube Under Fluoroscopy to Treat Esophagojejunal Anastomotic Fistula After Gastrectomy for Gastric Cancer

Background Esophagojejunal anastomotic leakage is a serious complication after total gastrectomy. This study evaluated the safety and efficacy of transnasal placement of drainage tube, jejunal decompression tube, and jejunal nutrition tube under fluoroscopy for treatment of esophagojejunal anastomotic fistula after gastrectomy in gastric cancer patients. Methods Retrospective review of patients with esophagojejunal anastomotic fistula treated with transnasal placement of abscess drainage tube, decompression tube, and jejunal nutrition tube under fluoroscopy. Fistula healing time, patient survival, and Eastern Cooperative Oncology Group (ECOG) performance status before and after treatment were evaluated. Results Thirty-eight patients were included in the study. Insertion of the transnasal abscess drainage tube, jejunal decompression tube, and nutrition tube was successful on the first attempt in all patients. Simple transnasal drainage was used in 27 patients (one drainage tube placed plus one drainage tube replacement in 15 patients, and one drainage tube placed in 12 patients), and transnasal drainage plus percutaneous abscess drainage in 11 patients. After placement of the tube, the mean volume of drainage was 120 ml (10–850 mL); the amount steadily decreased from then on. The fistula healed in 33 patients. Median time to fistula healing was 78 days (6-248 days). Two patients suffered gastrointestinal bleeding after the procedure but one patient died. Conclusions Transnasal insertion of transnasal abscess drainage tube, jejunal decompression tube, and jejunal nutrition tube under fluoroscopy appears to be a simple, minimally invasive, effective, and safe method for treating esophagojejunal anastomotic fistula after gastrectomy for gastric cancer.

Unusual treatment for calcifying odontogenic cyst using decompression tube to prevent pathological fracture

The calcifying odontogenic cyst (COC) is an uncommon lesion, with variable clinical and histopathological behavior. The cystic form is the most frequent and the most common histological characteristic is the presence of a variable number of phantom cells in the epithelial component. The standard treatment for this injury is enucleation followed by curettage or excision. However, when other factors are associated, this single-step approach can lead to complications such as pathological fractures. A common treatment for keratocysts and dentigerous cysts, but uncommon for COC has been showing high effectiveness. Thus, a two-stage approach using a tubular object to perform initial decompression of the lesion and later excision of the lesion can be performed in order to prevent complications. Here we report a two-stage treatment, through initial surgical decompression, of a COC associated with a lower second molar in the mandibular basilar region, using a tubular device, in which a pathological fracture was prevented. The results of this case corroborate the use of decompression applied to the treatment of COC.
