ABSTRACT
BACKGROUND: Intestinal flora disorder (IFD) poses a significant challenge after laparoscopic colonic surgery, and no standard criteria exists for its diagnosis and treatment. AIM: To analyze the clinical features and risk factors of IFD. METHODS: Patients with colon cancer receiving laparoscopic surgery were included using propensity-score-matching (PSM) methods. Based on the occurrence of IFD, patients were categorized into IFD and non-IFD groups. The clinical characteristics and treatment approaches for patients with IFD were analyzed. Multivariate regression analysis was performed to identify the risk factors of IFD. RESULTS: The IFD incidence after laparoscopic surgery was 9.0% (97 of 1073 patients). After PSM, 97 and 194 patients were identified in the IFD and non-IFD groups, respectively. The most common symptoms of IFD were diarrhea and abdominal, typically occurring on post-operative days 3 and 4. All patients were managed conservatively, including modulation of the intestinal flora (90.7%), oral/intravenous application of vancomycin (74.2%), and insertion of a gastric/ileus tube for decompression (23.7%). Multivariate regression analysis identified that pre-operative intestinal obstruction [odds ratio (OR) = 2.79, 95%CI: 1.04-7.47, P = 0.041] and post-operative antibiotics (OR = 8.57, 95%CI: 3.31-23.49, P < 0.001) were independent risk factors for IFD, whereas pre-operative parenteral nutrition (OR = 0.12, 95%CI: 0.06-0.26, P < 0.001) emerged as a protective factor. CONCLUSION: A stepwise approach of probiotics, vancomycin, and decompression could be an alternative treatment for IFD. Special attention is warranted post-operatively for patients with pre-operative obstruction or early use of antibiotics.
ABSTRACT
PURPOSE: This study surveyed the current practice of surgical treatment of obstructive left-sided colon cancer (OLCC) in China. METHODS: All colorectal surgery departments at tertiary or secondary hospitals in China were invited to complete a web-based questionnaire between August 27 and September 2, 2020. RESULTS: Overall, completed questionnaire were received from 357 hospitals. Emergency surgery was the mainstay of treatment for OLCC, with the open approach accounting for up to 61.62%. The stoma rate of emergency surgery was up to 80%, mainly due to inadequate bowel preparation and severe edema of colon walls. Hartmann's procedure (61.62%) was the most preferred operation. A total of 243 hospitals (68.7%) reported that they would consider the use of a self-expanding metallic stent (SEMS) as a bridge for elective surgery. More than 50% of the hospitals participating in this study reported the success rate of SEMS placement, as well as the resolution rate of obstruction more than 80%, and the stent-related perforation rate was < 5%. A total of 126 hospitals considered carrying out a strategy of SEMS followed by neoadjuvant chemotherapy prior to elective surgery and believed that it might further improve treatment outcomes. CONCLUSIONS: SEMS is a feasible option for the treatment of OLCC in addition to traditional emergency surgery, and its clinical benefits have been preliminarily recognized.

Anal adenocarcinoma combined with perianal Paget's disease (PPD) involving the vulva is rare, and there is no established standard treatment. We present the case of a 69-year-old woman with symptoms of intermittent hematochezia and perianal discomfort for 7 months. Upon examination, we discovered a plaque-like hard mass on the right posterior wall of the anal canal, which extended to encompass the anus and dentate line. The lesion skin also extended forward from the gluteal groove, involving the bilateral labial area. Colonoscopy revealed an extensive protruding lesion on the dentate line, which was confirmed as anal adenocarcinoma (mrT4N0M0). The presence of Paget's cells in perianal and vulvar skins led to the diagnosis of PPD. The strategy of neoadjuvant chemoradiotherapy (nCRT) followed by radical surgery was then made after multi-disciplinary discuss. The scope and extent of perianal and vulvar disease were significantly diminished after nCRT. The patient underwent laparoscopic abdominoperineal resection and vulvar lesion resection, confirming the diagnosis of anal adenocarcinoma (ypT2N0). No evidence of tumor cells was found in perianal and vulvar skin, indicating a complete response. The patient is regularly monitored without recurrence or metastasis.
ABSTRACT
OBJECTIVE: To evaluate the efficacy and safety of black tomato concentrate (BTC), which is rich in polyphenols, in the treatment of ED. METHODS: We conducted a prospective randomized open clinical study of 150 ED patients from December 2018 to February 2020, and treated the them with placebo (n = 50), BTC (n = 50) and Compound Xuanju Capsules (CXC) (n = 50), respectively, all for 8 weeks. Before and at 4 and 8 weeks after treatment, we obtained the scores of the patients on IIEF-5, Erection Hardness Score (EHS), Sexual Encounter Profile (SEP-2,3) and General Assessment Questionnaire (GAQ-1,2), related biochemical indexes and the T level, followed by comparison among the three groups. RESULTS: Totally, 120 of the patients completed the clinical trial, 37 in the placebo, 43 in the BTC and 40 in the CXC group. There were no statistically significant differences among the placebo, BTC and CXC groups in the baseline scores on IIEF-5 (12.03 �� 3.50 vs 11.70 �� 3.80 vs 11.42 �� 3.82), EHS, and SEP-2,3 (P > 0.05). At 8 weeks after treatment, the patients in the BTC group showed significant improvement in IIEF-5 (15.67 �� 3.63), EHS, SEP-2,3 and GAQ-1 positive response compared with those in the placebo group (P < 0.05) and similar improvement to that in the CXC group in IIEF-5 (15.67 �� 3.63 vs 15.65 �� 3.87), EHS, SEP-2,3 and GAQ-1,2 (P > 0.05). No statistically significant differences were observed in the incidence of adverse reactions among the placebo, BTC and CXC groups (4.7% vs 2.7% vs 5.0%, P > 0.05), and the symptoms were significantly relieved in the BTC group after change of the administration time to after meal. CONCLUSION: Black tomato concentrate is comparable to Compound Xuanju Capsules and better than placebo (P < 0.05) in improving the IIEF-5, EHS and SEP-2,3 scores of ED patients. And, with a high safety, it can be used as an alternative treatment of ED.

BACKGROUND: Alimentary duplication is a rare congenital disease with a reported incidence of 1 per 4500 persons, although the exact incidence has been difficult to ascertain. According to previous reports, the most common site of duplication is the ileum, and colonic duplication is rare. Due to different types and locations of the duplication, the manifestations are varied, which makes establishing an accurate diagnosis before surgery a challenge. CASE SUMMARY: A 17-year-old female patient sought evaluation in our department with constipation and chronic abdominal pain for 12 years; she had difficulty defecating and had dry stools since she was a child. An abdominal computed tomography revealed two extremely enlarged loops of bowel full of stool-like intestinal contents in the left lower abdomen, which led us to consider the possibility of colonic duplication. A laparoscopic exploration was performed, which revealed a tubular duplicated colon that shared a common opening with the transverse colon. A left hemi-colectomy was performed with a side-to-side anastomosis. The pathologic results confirmed the diagnosis. At the 6-mo follow-up, the patient was doing well without constipation or abdominal pain. CONCLUSION: Colonic duplication is a rare alimentary abnormality in adults. Due to the non-specific manifestations and low incidence, it is usually difficult to make an accurate diagnosis pre-operatively. Surgery is the mainstay of treatment, even though some patients are asymptomatic.
