A 57-year-old man underwent emergency laparoscopic loop colostomy for acute recto-sigmoid obstruction. He was hospitalised 2 months previously, at another facility for diabetic ketoacidosis (DKA) and hyperkalaemia. He had no gastrointestinal symptoms prior to the hospitalisation. Both surgical exploration and intraoperative sigmoidoscopy showed ulcerations of sigmoid colon and proximal rectum with a pinhole stricture in mid-rectum. After ruling out all aetiologies, and due to persistence of the colonic ulcerations on a follow-up colonoscopy, a diagnosis of Crohn’s colitis was made, and the patient was started on infliximab and 6-mercaptopurine (6-MP). Six months later, on rereview of all the biopsies, it was noted that a key element of presence of crystals suggestive of Kayexalate on the initial colorectal biopsies was missed. It was later found out that the patient had received rectal Kayexalate for treatment of DKA at the other facility. Hence, infliximab and 6-MP were both discontinued. All the colonoscopies, following the discontinuation of the medications, showed complete resolution of colitis but persistence of the mid-rectum stricture. This was treated with a fully covered metal stent for 12 weeks with only partial improvement of the stricture. He was hence referred for ultra-low anterior resection of rectum and take down of colostomy.

Introduction: Evaluation of the quality of life of patients with upper and middle rectal cancer treated with laparoscopic low anterior resection. Material and method: Prospective and previous research from 1/2013 to 9/2019 at Hue central hospital, a laparoscopic low anterior resection was performed in 86 patients with upper and mid rectal cancer. Result: There were 40 males and 45 females with the mean age of 62,95 ± 13,13; no conversion, have seven cases anastomotic leakage. Mean follow-up duration 60 months: have five cases local recurrence (5,9%), the overall survival rate after 5 years was 45%. Quality of Life of Patients is quiet good. Conclusion: Laparoscopic low anterior resection for treatment upper and mid rectal cancer is safe and effective, quality of life of patient is quite good.

Abstract Aim To analyze the effect of preserving the left colic artery (LCA) on long-term oncologic outcomes during laparoscopic low anterior resection of rectal cancer. Methods Clinicopathological and follow-up patients undergoing laparoscopic low anterior resection of rectal cancer in general surgery department of Guangdong Provincial People's Hospital from January 2014 to December 2015 were retrospectively collected. According to the difference surgical methods of inferior mesenteric artery (IMA), 159 cases were divided into the LCA preservation group and 225 cases in the LCA non-preservation group. The 5-year rates of overall survival (OS) and disease-free survival (DFS) were compared between two group. Results 384 patients were included in final analysis. Anastomotic leakage occurred in 7 patients (4.4%) in the LCA preservation group and in 16 patients (7.1%) in the LCA non-preservation group. The follow-up rate was 91.2% (145/159) during 5–60 months in LCA preservation group, and 89.8% (202/225) during 5–60 months in the LCA non-preservation group. The number of patients who developed death, local recurrence and metastasis were 59 (37.1%), 13 (8.2%) and 60 (37.7%) in the LCA preservation group, and 86 (38.2%), 20 (8.9%) and 92 (40.9%) in the LCA non-preservation group, without significant differences (all P ༞ 0.05). The 5-year OS and DFS rates were 69.0% and 59.3% in the LCA preservation group, and 68.8% and 55.9% in the LCA non-preservation group, without significant differences (all P ༞ 0.05). After stratification by TNM Stage, the difference on 5-year OS rates and DFS rates of I stage, II stage and III stage in two groups were no significant as well (all P ༞ 0.05). Conclusions The long-term oncologic outcomes of laparoscopic low anterior resection of rectal cancer with preservation of the LCA are comparable with ligation at origin of IMA.

Abstract Background Laparoscopic, robot-assisted, and transanal total mesorectal excision are the minimally invasive techniques used most for rectal cancer surgery. Because data regarding oncologic results are lacking, this study aimed to compare these three techniques while taking the learning curve into account. Methods This retrospective population-based study cohort included all patients between 2015 and 2017 who underwent a low anterior resection at 11 dedicated centers that had completed the learning curve of the specific technique. The primary outcome was overall survival (OS) during a 3-year follow-up period. The secondary outcomes were 3-year disease-free survival (DFS) and 3-year local recurrence rate. Statistical analysis was performed using Cox-regression. Results The 617 patients enrolled in the study included 252 who underwent a laparoscopic resection, 205 who underwent a robot-assisted resection, and 160 who underwent a transanal low anterior resection. The oncologic outcomes were equal between the three techniques. The 3-year OS rate was 90% for laparoscopic resection, 90.4% for robot-assisted resection, and 87.6% for transanal low anterior resection. The 3-year DFS rate was 77.8% for laparoscopic resection, 75.8% for robot-assisted resection, and 78.8% for transanal low anterior resection. The 3-year local recurrence rate was in 6.1% for laparoscopic resection, 6.4% for robot-assisted resection, and 5.7% for transanal procedures. Cox-regression did not show a significant difference between the techniques while taking confounders into account. Conclusion The oncologic results during the 3-year follow-up were good and comparable between laparoscopic, robot-assisted, and transanal total mesorectal technique at experienced centers. These techniques can be performed safely in experienced hands.

Abstract BackgroundThere is uncertainty in the literature about the best surgical approach for low anterior resection of rectal cancer to deal with the inferior mesenteric artery (IMA), that is to preserve left colic artery or not. We analyzed the effect of preserving the left colic artery (LCA) on long-term oncological outcomes. MethodsWe retrospectively collected clinicopathological and follow-up details of patients who underwent low anterior resection for rectal cancer in the General Surgery Department of Guangdong Provincial People's Hospital, from January 2014 to December 2015. Cases were divided into low ligation (LL) or high ligation (HL) of the IMA The 5-year overall survival (OS) and disease-free survival (DFS) rates were compared between the two groups. ResultsAltogether, there were 221 cases in the LL group (LCA preserved) and 295 cases in the HL group (LCA not preserved). Postoperative 30-day mortality was 0.9% in the LL group and 1.4% in the HL group. Early complications occurred in 41.2% patients in the LL group and 38.3% in the HL group. Anastomotic leakage occurred in 8.6% of patients in the LL group and in 13.2% in the HL group. The numbers of lymph nodes harvested were 18.8 ± 9.6 in the LL group and 17.0 ± 6.6 in the HL group. The median follow-up periods were 51.4 (7–61) months in the LL group and 51.2 (8–61) months in the HL group. During follow-up, the percentages of patients who died, had local recurrence, or had metastases were 39.8%, 7.7%, and 38.5%, respectively, in the LL group and 39%, 8.5%, and 40%, respectively, in the HL group; these differences were not significant (all P > 0.05). The 5-year OS and DFS were 69.6% and 59.6% in the LL group, respectively, and 60.1% and 56.2% in the HL group, respectively; these differences were not significant (all P > 0.05). After stratification by tumor-node-metastasis stage, the difference between the 5-year OS and DFS for stages I, II, and III cancer were not significant (all P > 0.05). ConclusionsThe long-term oncological outcomes of low anterior resection for rectal cancer with preservation of the LCA are comparable with those of ligation at the IMA origin.
