RESUMO
Objectives: The present study reviewed cases of Toxic megacolon (TM) treated in our department, summarized the timing and technique of surgery, and considered key points for surgical management. Methods: This single-center retrospective study included the medical records of patients clinically diagnosed with TM who underwent surgery between 1985 and 2020. The diagnostic criteria and screening scores for sepsis, such as the systemic inflammatory response syndrome (SIRS) criteria, quick Sequential Organ Failure Assessment (qSOFA) score, and Modified Early Warning Score (MEWS), were validated. The preoperative clinical features and perioperative findings were also investigated. Results: There were eight male and six female patients. Nine patients (64.3%) satisfied the criteria for toxemia proposed by Narabayashi, and 10 patients (71.4%) fulfilled the SIRS criteria. A positive qSOFA score was confirmed in 1 patient (7.1%). The MEWS was high in 2 patients (14.3%). Intestinal perforation occurred in 2 patients (14.3%), and 1 of them died from disseminated intravascular coagulation. The mortality rate of TM with perforation was 50%. Eleven patients (78.6%) underwent total colectomy with end ileostomy. Conclusions: TM does not have well-defined diagnostic criteria, in addition to developing sometimes as borderline or fulminant cases, and must be recognized at an early stage, taking various findings into consideration. The criteria proposed by Narabayashi and the SIRS criteria, which met in a high percentage of our cases, are recommended as indicators for determining the toxicity of TM. It is also important to consider surgery in the early stages of TM, even if clinical findings do not meet all the criteria.
RESUMO
BACKGROUND/AIM: Self-expandable metallic stent (SEMS) placement is becoming the standard bridge-to-surgery (BTS) strategy for potentially curable left-sided obstructive colorectal cancer (OCRC). The study objective was to evaluate the effectiveness of SEMS placement as a BTS strategy for both right- and left-sided OCRC. PATIENTS AND METHODS: We retrospectively compared the short- and long-term outcomes of patients with OCRC who underwent placement of a SEMS versus a trans-nasal/anal decompression tube (DCT). The cohort comprised 57 patients with stage II/III right-sided OCRC (DCT, n=20; SEMS, n=8) or left-sided OCRC (DCT, n=9; SEMS, n=20). The short-term outcomes were the incidence of postoperative complications, rate of laparoscopic surgery, rate of stoma construction, and postoperative hospital stay; long-term outcomes were the 3-year overall survival (OS) and relapse-free survival (RFS). RESULTS: The SEMS group had a higher rate of laparoscopic surgery (85.7% vs. 6.9%, p<0.001), lower rate of stoma construction (10.7% vs. 34.5%, p=0.03), and shorter postoperative hospital stay (14 vs. 17 days, p=0.04) than the DCT group. Both groups had a similar incidence of postoperative complications. The 3-year OS and RFS were also similar in the DCT and SEMS groups for both right-sided OCRC (OS, 75.0% vs. 87.5%, HR=1.51, 95% CI=0.22-10.25, p=0.7; RFS, 65.0% vs. 50.0%, HR=0.97, 95% CI=0.28-3.36, p=0.9) and left-sided OCRC (OS, 88.8% vs. 90.0%, HR=1.19, 95% CI=0.10-14.29, p=0.9; RFS, 77.8% vs. 85.0%, HR=1.03, 95% CI=0.16-6.5, p=0.9). CONCLUSION: SEMS placement is a reasonable BTS strategy for left- and right-sided OCRC that achieves comparable short- and long-term outcomes to DCT insertion.

PURPOSE: The current study summarized the clinical course and treatment outcomes of intestinal cancer in CD seen in our department and explored the steps to take in the future. METHODS: Subjects were patients who had been diagnosed with CD at our hospital and who underwent surgery in our department from 1985 to 2020. RESULTS: Thirty-one patients had CD and intestinal cancer, including 6 with cancer of the small intestine and 25 with cancer of the large intestine. In all six patients with cancer of the small intestine, the site where cancer or a tumor developed was at or near the site of the anastomosis made at a previous surgery. Of the 25 patients with cancer of the large intestine, 22 developed cancer in the rectum or anal region. CONCLUSION: Many of the patients with cancer of the small intestine had previously undergone surgery, and the cancer developed at or near the site of the anastomosis. In patients who have previously undergone resection of the small intestine, the small intestine needs to be examined regularly. Cancer of the large intestine often developed in the rectum or anal region of our patients, so a detailed examination of the same site needs to be performed.

A 77-year-old woman who had undergone laparoscopic pylorus-preserving gastrectomy for gastric cancer showed dilatation of the main pancreatic duct in the distal pancreas on ultrasonography during postoperative surveillance. Detailed examination revealed that she had a main-duct type intraductal papillary mucinous neoplasm with high-risk stigmata. As invasive malignancy was not suggested, laparoscopic splenic vessel-preserving distal pancreatectomy was performed to preserve the remnant stomach. Although adhesions around the gastroduodenostomy and splenic artery were severe, the magnified laparoscopic view facilitated the identification of appropriate dissection layers, resulting in limited blood loss. The distal pancreas was successfully resected without sacrificing blood flow to the remnant stomach. The postoperative course was uneventful. The pathological diagnosis was low-grade intraductal papillary mucinous neoplasm. Laparoscopic splenic vessel-preserving distal pancreatectomy for benign or low-grade malignant disease of the distal pancreas can be useful for preserving the remnant stomach in patients with a history of gastrectomy.
