Background Appendicitis is the most common cause of acute abdomen. Although emergency surgery used to be the standard treatment for both simple and complex appendicitis, there are now options for interval surgery, laparoscopic surgery, and even non-surgical treatment. In this study, we aimed to establish better treatment strategies for pediatric acute appendicitis and to find out whether minimally invasive treatment is superior to the traditional open approach. We retrospectively reviewed the cases of acute appendicitis treated in our hospital during the period from 2013 to 2018. The patients who underwent appendectomy were divided into four groups. Group 1 underwent early appendectomy with open approach, group2 underwent interval appendectomy with open approach, group 3 underwent early appendectomy with laparoscopic approach, and group 4 underwent interval appendectomy with laparoscopic approach. In addition to the above groups, the non-surgical treatment group was also studied. Clinical presentation, laboratory findings, imaging results, operative time, morbidity, and length of hospital stay were reviewed. Results One hundred six children’s records were reviewed. Thirty-five of them were selected for non-surgery as they were cases with no fecal stone and first onset appendicitis, and 15 of these 35 patients (42.9%) relapsed after antibiotic treatment. As for the appendix diameter, the relapse group was significantly larger than the non-relapse group (p=0.007). In cases of surgery, group 4 had significantly less intraoperative blood loss than group 1 (p<0.001). Group 4 had significantly fewer postoperative complications than groups 1 and 2 [group 4 vs. group 1 (p=0.009), group 4 vs. group 2 (p=0.034)]. The postoperative hospital stay in groups 2 and 4 were significantly shorter than group 1 [group 1 vs. group 2 (p=0.015), group 1 vs. group 4 (p<0.001)]. On the contrary, group 1 had significantly shorter total hospital stay than groups 2 and 4 [group 1 vs. group 2 (p=0.029), group 1 vs. group 4 (p<0.001)]. Conclusion Interval laparoscopic appendectomy and non-surgical treatment were safe and effective in children. From the viewpoint of avoiding unnecessary emergency surgery and prolonged hospitalization, we believe that interval laparoscopic appendectomy or non-surgical treatment should be performed after identifying patients who do not require surgery, paying attention to the risk factors for relapse.
Background Determine whether robotic surgery is more effective than transanal and conventional laparoscopic surgery in preserving bowel and urinary function after total mesorectal excision (TME). Methods Of 79 lower rectal cancer patients who underwent function-preserving TME between 2016 and 2020, 64 patients consented to a prospective questionnaire-based functional observation study (52 responded). At six months post-resection or ileostomy closure, Wexner, low anterior resection syndrome (LARS), modified fecal incontinence quality of life, and international prostate symptom scores were used to evaluate bowel and urinary function, comparing robotic surgery (RTME) with transanal (taTME) or conventional laparoscopic surgery (LTME). Results RTME was performed in 35 patients (54.7%), taTME in 15 (23.4%), and LTME in 14 (21.9%). While preoperative bowel/urinary functions were similar in all three procedures, and the distance from the anal verge to tumor was almost the same, more hand-sewn anastomoses were performed and the anastomotic height from the anal verge was shorter in taTME than RTME. At 2 years post-resection, 8 patients (12.5%) had a permanent stoma; RTME showed a significantly lower rate of permanent stoma than taTME (2.9% vs 40%, p < 0.01). Despite no significant difference, all bowel function assessments were better in RTME than in taTME or LTME. Major LARS was observed in all taTME and LTME cases, but only 78.8% of RTME. No clear difference arose between RTME and taTME in urinary function; urinary dysfunction was more severe in LTME than RTME (36.4% vs 6.1%, p = 0.02). Conclusions In function-preserving TME for lower rectal cancer, robotic surgery was suggested to be more effective than transanal and conventional laparoscopic surgery in terms of bowel and urinary functions.
