Abstract

Low‐grade appendiceal mucinous neoplasm (LAMN) is principally characterized by low‐grade cytology without evidence of invasion to other organs. We report a LAMN surgical case whose appendiceal tumor penetrated the sigmoid colon wall. An 87‐year‐old man was referred for endoscopic resection (ER) of a colon polyp. Despite four ERs over 5 years, the polyp recurred at the same site. Laparoscopic surgery revealed a dilated appendix firmly attached to the sigmoid colon. We performed en bloc resection of both the sigmoid colon and appendix without tumor exposure. The histopathological evaluation showed that the LAMN had penetrated the sigmoid colon wall, forming two polyps on the colonic mucosa. In cases where the appendiceal‐colonic fistula is suspected, en bloc resection of the appendix and colon wall should be considered. [ABSTRACT FROM AUTHOR]

Abstract

Background: Intensive localized therapy is promising for the treatment of rectal cancer. In Japan, chemoradiotherapy (CRT) and neoadjuvant chemotherapy (NAC) are used as preoperative treatments for this disease. Magnetic resonance imaging (MRI) is used to diagnose lateral pelvic node (LPN) metastases, but the changes in LPN findings on MRI following preoperative treatment are unclear. Furthermore, there may be patients in whom LPN dissection can be omitted after CRT/NAC. Methods: Patients who underwent total mesorectal excision with LPN dissection after CRT/NAC at 13 Japanese Society for Cancer of the Colon and Rectum member institutions between 2017 and 2019 were included. Changes in the short diameter of the LPNs after CRT/NAC and the reduction rate were examined. Results: A total of 101 LPNs were examined in 28 patients who received CRT and 228 in 47 patients who received NAC. Comparison of LPNs before and after CRT/NAC showed that most LPNs shrank after CRT but that the size reduction was variable after NAC. Although some LPNs with a short diameter of <5 mm showed residual metastasis, no metastases were observed in LPNs that were <5 mm in short diameter before and after CRT/NAC and did not shrink after treatment. Conclusion: Although the short diameter of LPNs was significantly reduced by both CRT and NAC, even LPNs with a short diameter of <5 mm could have residual metastases. However, dissection may be omitted for LPNs <5 mm in short diameter that do not shrink after preoperative CRT or NAC. [ABSTRACT FROM AUTHOR]

32. Articulating forceps in laparoscopic total mesorectal excision: A video comparison with robotic surgery.

Abstract

Introduction: Total mesorectal excision (TME) is an established standard procedure for rectal surgery; however, it is technically challenging because of the deep and narrow pelvis. Minimally invasive surgeries have gained prominence for TME with favorable outcomes but come with limitations. Laparoscopic surgery often has dexterity restrictions because of the use of straight forceps, whereas robotic surgery is impeded by high costs and extended operative times. Articulating forceps aim to bridge the gap between these methods by offering enhanced dexterity at a lower cost. Patients and Surgical Technique: This video study involves two female patients diagnosed with lower rectal cancer. One patient underwent laparoscopic intersphincteric resection (Lap‐ISR) using the ArtiSential articulating forceps (LIVSMED Inc.), and the other underwent robot‐assisted low anterior resection (Rob‐LAR) using the da Vinci Xi System. Both operations involved similar mesorectal dissection steps, except for the anastomosis. The standard port placement was used, and dissection was performed circumferentially down to the perianal region. Discussion: The ArtiSential demonstrated effectiveness comparable with the da Vinci Xi system in TME surgery, with the potential advantage of improved cost‐effectiveness. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: Esophagectomy is the primary surgical treatment for esophageal cancer, although other treatment approaches are often incorporated, including preoperative chemotherapy and chemoradiotherapy. The two major routes of esophageal reconstruction after esophagectomy are the anterior mediastinal (retrosternal, heterotopic) and posterior mediastinal (prevertebral, orthotopic) routes. However, which of these two routes of reconstruction is the most appropriate remains controversial. This systematic review aimed to compare the efficacy and safety of anterior mediastinal reconstruction with those of posterior mediastinal reconstruction after esophagectomy in esophageal cancer. Methods: In January 2022, a literature search of the CENTRAL, MEDLINE, and EMBASE databases was conducted to identify all published and unpublished randomized controlled trials, regardless of language. Eight studies were included for quantitative synthesis. Results: Postoperative death (9/129 and 4/125, risk ratio [RR]: 2.07, 95% confidence interval [CI]: 0.65–6.64) and incidence of anastomotic leak (24/208 and 26/208, RR: 0.95, 95% CI: 0.56–1.62) were not significantly different between the two mediastinal reconstructions. We could not perform a meta-analysis for quality of life, loss of body weight, or postoperative hospital stay due to data limitations. Conclusion: Overall, there was low-quality evidence to suggest that the outcomes of the anterior and posterior mediastinal routes of reconstruction are not significantly different in patients with esophageal cancer.
