ABSTRACT
PURPOSE: Limited data exist on the use of low midline and transverse incisions for specimen extraction or stoma sites in laparoscopic rectal cancer surgery (LRCS). We compared the short-term and medium-term outcomes of these incisions and assessed whether wound complications in specimen extraction sites (SES) are increased by specimen extraction through the stoma site (SESS) in LRCS. METHODS: From March 2010 to December 2017, 189 patients who underwent LRCS and specimen extraction through low abdominal incisions were divided into 2 groups: midline (n = 102) and transverse (n = 87), and perioperative outcomes were compared. RESULTS: The midline group showed a higher frequency of temporary stoma formation (P = 0.001) and splenic flexure mobilization (P < 0.001) than the transverse group. The overall incisional hernia and wound infection rates in the SES were 21.6% and 25.5%, respectively, in the midline group and 26.4% and 17.2%, respectively, in the transverse group (P = 0.494 and P = 0.232, respectively). In patients who underwent SESS, the incisional hernia and wound infection rates of SES after stoma closure were 39.1% and 43.5%, respectively, in the midline group, and 35.5% and 22.6%, respectively, in the transverse group (P = 0.840 and P = 0.035, respectively). CONCLUSION: In terms of incisional hernia and wound infection at the SES, a low midline incision may be used as a low transverse incision in patients without temporary stoma in LRCS. However, considering the high wound complication rates after stoma closure in patients with SESS in this study, SESS should be performed with caution in LRCS.
ABSTRACT
A survey was performed to investigate the infection status of zoonotic helminth larvae in fish from a local market of North Dagon District in Yangon City, Myanmar. A total of 486 fish in 13 species were collected 8 times from December 2015 to December 2019. All fish were transported under ice to a laboratory in Korea and examined for helminth larvae using artificial digestion method. Larval gnathostomes and metacercariae of more than 8 zoonotic trematode species, i.e., Opisthorchis viverrini, Haplorchis taichui, H. pumilio, H. yokogawai, Centrocestus spp., Stellantchasmus falcatus, Pygidiopsis cambodiensis, and Procerovum sp., were detected. Larval gnathostomes were found in 58 (16.0%) out of 362 fish of 6 species, with mean intensity of 2.8 per fish infected. Metacercariae of O. viverrini were detected in 10 (2.9%) out of 349 fish of 5 species, with mean intensity of 16.9 per fish infected. Metacercarial prevalences of 4 intestinal flukes, H. taichui, H. pumilio, H. yokogawai, and Centrocestus spp., were 16.8%, 26.0%, 12.5%, and 15.0% in the positive fish species, respectively, and mean metacercarial intensity was 63.3, 26.8, 86.2, and 8.7 per fish infected. Metacercariae of S. falcatus and P. cambodiensis were detected only from the mullet, Chelon macrolepis. Metacercariae of Procerovum sp. were found in Channa striata and Anabas testudineus. Collectively, it was confirmed that the fish were infected with gnathostome larvae and metacercariae of O. viverrini and intestinal flukes in Yangon City, Myanmar.
