Diverticular disease of the colon occurs quite frequently in developed countries, and its prevalence has recently increased in Japan. The appearance of diverticulosis increases with age, although mostly remaining asymptomatic. Approximately 20% of cases require treatment. As the Western lifestyle and number of elderly people increase, the need for medical treatment also increases. Computed tomography (CT) is the gold standard for diagnosing diverticulitis. Complicated diverticulitis is classified by the size and range of abscess formation and the severity of the peritonitis. Each case should be classified based on clinical and computed tomography (CT) findings and then treated appropriately. Most patients with uncomplicated diverticulitis (stages 0–Ia) can be treated conservatively. Diverticulitis with a localized abscess (stages Ib–II) is generally resolved with conservative treatment. If the abscess is larger or conservative treatment fails, however, percutaneous drainage or surgery should be considered. Operative treatment is considered standard therapy for severe diverticulitis with perforation and generalized peritonitis (stages III–IV). Colonic diverticulitis treated conservatively frequently recurs. Elective surgery after recovery should be considered carefully and decisions made on a case‐by‐case basis. Because cases of colonic diverticulitis will undoubtedly increase in Japan, it is likely that we will be confronted with increasing numbers of treatment decisions. We therefore need to have a systematic strategy for treating the various stages of colonic diverticulitis appropriately. We herein review the management of complicated diverticulitis.
A 67-year-old male was referred to our hospital after being diagnosed with esophageal squamous cell carcinoma of the middle thoracic esophagus. The clinical stage was T1b(sm)N4M1 cStage IVb, so he was admitted to our hospital for systemic chemotherapy. He had sustained fever and a dry cough. Chest computed tomography showed the presence of irregular shadows, and unidentified respiratory insufficiency had progressed. A transbronchial lung biopsy revealed a pulmonary artery tumor embolus of esophageal squamous cell carcinoma. He developed DIC and died of respiratory failure on the 19th hospital day. The postmortem autopsy detected pulmonary tumor thrombotic microangiopathy accompanied by esophageal squamous cell carcinoma.
Abstract:There are several reports on the usefulness of diverting ileostomy for decreasing the incidence of anastomotic leakage and the severity of pelvic peritonitis. However, a number of complications induced by ileostomy itself have also been reported, including a special condition induced by obstruction at the outlet of the stoma known as "outlet obstruction." In this study, we examined the frequency and risk factors of this complication based on the data of ileostomy cases in our institution. Methods: One hundred and seven patients who received ileostomy creation at our department from January 2010 to December 2015 were included. The incidence of outlet obstruction and risk factors were analyzed. Results: Outlet obstruction occurred in 18 cases (16.8%). The incidence was significantly higher in total colectomy or proctocolectomy cases as well as in those with left side construction and laparoscopic surgery than in other patients in a univariate analysis. However, in a multivariate analysis, no risk factors were extracted. Conclusions: To determine the true cause of this disease, a prospective study with a large number of cases is needed. Since multiple terms are used for this condition, resulting in confusion, a consensus on the appropriate terms is also important.
Purpose: S-1 is widely used for various cancers. It may be useful for esophageal squamous cell carcinoma (ESCC); however, there are insufficient data. The purpose is to provide results of an analysis of S-1 monotherapy for unresectable and recurrent ESCC. Patients and Methods: Twenty patients with histologically proven ESCC who were previously treated with other chemo(radio)therapies were treated with S-1 alone as second- or third-line chemotherapy. Results: A complete response (CR) was observed in 1 case (5%). A partial response (PR), stable disease (SD), and progressive disease (PD) were seen in 4 (20.0%), 7 (35.0%), and 8 (40.0%) cases, respectively. Two cases (10%) of anemia, 1 case (5%) of leukopenia, 3 cases (15%) of fatigue, and 3 cases (15%) of diarrhea were observed as grade 3 toxicity; however, there were no cases of grade 4 toxicity. The 1-year progression-free survival (PFS) rate was 10.0%, and the median PFS was 100 days. The 1-year overall survival (OS) was 30.5%, and the median OS was 330 days. The 1-year PFS rate in CR/PR/SD and PD was 16.7 and 0%, and the median survival time was 120 and 40 days. Conclusion: S-1 is a promising new drug which can be used as a second- or third-line chemotherapy for ESCC.
