RESUMO
Objective: To understand the late reporting and the under-reporting of occupational disease from 2018 to 2020 in China and analyze the causes, so as to provide scientific evidence for improving the quality of occupational disease reports in China, timely acquiring the incidence of occupational disease, and assessing the occupational hazards. Methods: From May to December 2021, A total of 320 occupational disease diagnostic institutions were selected for investigation. The original documents of occupational disease diagnosis cases from 2018 to 2020 were compared with the online reported cases, and late reported and under-reported cases of occupational disease were analyzed. Results: A total of 32207 diagnosed cases from 2018 to 2020 were investigated, including 28934 confirmed cases and 3273 cases without occupational disease. The overall late reported rate and under-reported rate of confirmed cases were 20.2% and 2.1%, respectively. There were significant differences in the rate of late reporting and under-reporting of occupational diseases in different regions and different types of diagnostic institutions (P<0.001). The southwest region had the highest rates of late reporting and under-reporting, 61.6% and 7.9% respectively. The late reported rate of all kinds of occupational diseases was about 15.0%, and the under-reported rate was from 1.5.0% to 5.0%. Conclusion: At present, the phenomenon of late reporting and under-reporting occupational diseases is still obvious. It is necessary to strengthen the inspection of occupational disease reporting, improve the quality of occupational disease reporting, and provide scientific basis for the formulation of occupational disease prevention and control policies.

<p><b>OBJECTIVE</b>To evaluate the feasibility and efficacy of laparoscopic anterior resection of rectal carcinoma with preservation of the left colonic artery.</p><p><b>METHODS</b>From February 2006 to February 2009, 52 patients with rectal carcinoma formerly scheduled for Dixon operation (clinical stage I and II) received laparoscopic Dixon surgery. The inferior mesenteric artery, left colonic artery, sigmoid artery or superior rectal artery, and lymph nodes were dissected through the vasa vasorum approach. The left colonic artery was retained by transecting the inferior mesenteric artery inferior to the left colonic artery. The operative time, intraoperative hemorrhage volume, intraoperative complications, anastomotic tension, number and histopathological features of the dissected lymph nodes surrounding the inferior mesenteric artery, and the rates of local recurrence, lymph node metastasis and anastomotic leakage were analyzed.</p><p><b>RESULTS</b>The operation was successfully completed in all the 52 cases. The operative time ranged from 115 to 320 min with a mean of 150 min. The mean intraoperative hemorrhage was 25 ml (range 15-75 ml). None of the patients had perforation of the rectum, injuries to blood vessel, ureter or adjacent organs, or anastomotic tension. The number of dissected lymph nodes surrounding the inferior mesenteric artery ranged from 4 to 8, with a mean of 6.2. The dissected lymph nodes in the base of the inferior mesenteric artery showed no cancer cell metastasis, while 4 patients had cancer cell metastasis in the lymph nodes surrounding superior rectal artery. None of patients had anastomotic leakage. Local recurrence was found in only 1 case at 7 months after the operation.</p><p><b>CONCLUSION</b>Laparoscopic anterior resection of the rectal carcinoma with preservation of the left colonic artery can be completed in patients with rectal carcinoma planning to receive Dixon operation (clinical stage I or II). This surgical approach preserves more supplying vessels and prevents anastomotic leakage without increasing the anastomotic tension or affecting lymph node dissection surrounding the inferior mesenteric artery.</p>
