Between the years 1984 and 1988, 43 patients with bulky advanced stage epithelial ovarian carcinoma underwent en bloc pelvic resection with excision of the rectosigmoid colon as part of their primary cytoreductive surgery. Optimal cytoreduction was accomplished in over 70% of cases, and all women had complete debulking of their pelvic tumor. Primary anastomosis of the bowel was feasible in all cases and only two covering colostomies were performed. There were no postoperative leaks or fistulas. The postoperative morbidity was reflected by a mean postoperative hospital stay of 16 days. Our results suggest that this technique facilitates optimal cytoreduction of bulky pelvic tumor with an acceptably low morbidity in woman with advanced ovarian carcinoma.

Abstract Background and study aims Adequate mucosal elevation by submucosal injection is crucial for patient safety and efficiency during endoscopic submucosal dissection (ESD). This study aimed to evaluate the efficacy of fibrin glue (FG) as a long-lasting submucosal injection agent and to evaluate the technical feasibility of FG injection for ESD. Materials and methods To compare the capabilities of different agents in maintaining submucosal evaluation, we injected FG, hyaluronic acid solution, and normal saline into the porcine gastric specimen that was incised into approximately 5 × 5 cm squares. Then, we measured the height of submucosal elevations over time. Moreover, three hypothetical lesions from the resected porcine stomach underwent ESD with FG injection. Thereafter, we conducted macroscopic and histopathologic analyses. Results FG maintained the greatest submucosal elevation among all the injection agents. Three ESD procedures were performed with en bloc resection. Both macroscopic and histopathologic findings showed a thick FG clot on the ulcers. Conclusions The FG solution can be potentially used as an ESD submucosal injection agent in an in vitro model.

Colorectal Endoscopic Submucosal Dissection

Abstract Background and study aims The pocket-creation method (PCM) facilitates dissection of the central part of a tumor. We previously developed the PCM with clip traction (PCM-CT) to facilitate opening the mucosal pocket, which otherwise could become cumbersome. In the present study, we aimed to examine the feasibility of PCM-CT for colorectal endoscopic submucosal dissection (ESD). Patients and methods PCM-CT was performed on 30 patients with early colorectal tumors from October 2019 to April 2020. PCM-CT allows efficient opening of the mucosal pocket by using the PCM to dissect the center of the lesion and then apply traction with a single clip after making a circumferential mucosal incision. Results The median specimen major axis length, ESD time, ESD speed, and en bloc resection rate were 48 mm, 84 minutes, 20 mm2/min, and 100 % (30/30), respectively. The success rates for the traction clip and median single-clip-traction time were 100 % (30/30) and 1.5 minutes, respectively. Conclusions Colorectal ESD using PCM-CT is a simple and promising method.
