OBJECTIVES: To establish and to evaluate a machine learning radiomics model based on grayscale and Sonazoid contrast enhanced ultrasound images for the preoperative prediction of microvascular invasion (MVI) in hepatocellular carcinoma (HCC) patients. METHODS: 100 cases of histopathological confirmed HCC lesions were prospectively included. Regions of interest were segmented on both grayscale and Kupffer phase of Sonazoid contrast enhanced (CEUS) images. Radiomic features were extracted from tumor region and region containing 5 mm of peritumoral liver tissues. Maximum relevance minimum redundancy (MRMR) and Least Absolute Shrinkage and Selection Operator (LASSO) were used for feature selection and Support Vector Machine (SVM) classifier was trained for radiomic signature calculation. Radiomic signatures were incorporated with clinical variables using univariate-multivariate logistic regression for the final prediction of MVI. Receiver operating characteristic curves, calibration curves and decision curve analysis were used to evaluate model's predictive performance of MVI. RESULTS: Age were the only clinical variable significantly associated with MVI. Radiomic signature derived from Kupffer phase images of peritumoral liver tissues (kupfferPT) displayed a significantly better performance with an area under the receiver operating characteristic curve (AUROC) of 0.800 (95% confidence interval: 0.667, 0.834), the final prediction model using age and kupfferPT achieved an AUROC of 0.804 (95% CI: 0.723, 0.878), accuracy of 75.0%, sensitivity of 87.5% and specificity of 69.1%. CONCLUSIONS: Radiomic model based on Kupffer phase ultrasound images of tissue adjacent to HCC lesions showed an observable better predictive value compared to grayscale images and has potential value to facilitate preoperative identification of HCC patients at higher risk of MVI.

Laparoscopic anterior resection of rectum (AR) is one of surgical approaches for deeply infiltrating endometriosis (DIE). Up to date, no clinical trials have clearly analyzed the short-term and long-term complications post-surgically, indications or feasibilities for surgical procedure, or post-operative recovery. The aims of this trial were to evaluate the indications for laparoscopic AR, the short-term and long-term complications post-surgically, post-operative recovery.We conducted a prospective study of 29 patients. They were divided into 2 groups. The period of follow-up was 12 months post-surgery. In our study, we recruited patents with laparoscopic AR experiencing failure of medical treatment (3 months) or associated infertility (>2cycles). The operative data and short term and long term complications were recorded. The outcomes of laparoscopic AR group were assessed by questionnaires, such as NRS (numeric rating scale), KESS (Knowles-Eccersley-Scott Symptom Questionnaire), VAS (visual analogue scale), WCS (Wexner constipation score) and ABS (Abdominal Bloating Score), which were compared with the outcomes of medicine group at set time points of baseline, 3 months, 6 months, 9 months and 12 months. The overall outcomes of the two groups were assessed with 5-point Likert Scale.Patients in surgery group were recovery rapidly without serious short term or long term complications. All of NRS, KESS, VAS, WCS, and ABS in surgery group were getting better greatly than that in medicine group (3.04 ±â€Š1.91 vs 5.41 ±â€Š3.01, 5.64 ±â€Š1.54 vs 7.01 ±â€Š1.03, 0.50 ±â€Š0.38 vs 3.58 ±â€Š2.01, 4.43 ±â€Š1.02 vs 8.92 ±â€Š2.45, and 0.61 ±â€Š0.34 vs 1.42 ±â€Š0.71) at 3 months post-operation. However, the advantage of surgery group was almost vanished at 12 months (4.02 ±â€Š2.53 vs 5.99 ±â€Š2.31, 7.42 ±â€Š3.17 vs 10.98 ±â€Š2.53, 1.59 ±â€Š1.3 vs 2.23 ±â€Š1.59, 6.01 ±â€Š2.53 vs 7.90 ±â€Š3.25, and 1.31 ±â€Š1.05 vs 1.39 ±â€Š1.02). Furthermore, we compared the overall outcomes between the 2 groups with 5-point Likert Scale, with confirmation of the advantage at 3 months post-surgically. Additionally, we compared these questionnaires, with the finding that VAS and 5-point Likert Scale of surgery group had the same changes. Finally, a table of indications for laparoscopic AR were tabulated according our clinical experience.Patients can receive benefit from both medicine and laparoscopic AR. However, laparoscopic AR has obvious advantage of rapid symptom relief. Further studies and clinical data collections are required for indications and feasibility of combined therapy.

Perineal wound complications after APR have high morbidity in the colorectal surgical department. Although some approaches have been figured out to solve this clinical focus, the outcomes are still not satisfied. Herein, this prospective comparative clinical trial has been designed to evaluate a new surgical procedure of direct perineal wound full-thick closure (DPWC), compared with conventional perineal wound closure (CPWC), with hopes of making wound healing with less complications. In addition, an evaluation of an incision negative wound pressure therapy, as another focus in this field, was also analysed in the DPWC group. A total of 44 participants in our department were recruited from March 2018 to March 2020, divided into two groups randomly, CPWC group and DPWC group. The patients' characteristics, such as age, gender, BMI, smoking, alcohol consumption, comorbidities, CEA level, and high-risk of invasion, were recorded without statistical significance between the CPWC group and DPWC group. After the same standard abdominal phase, these two groups were performed in different perineal phases. And then, operative and postoperative outcomes were analysed with different statistical methods. Data on wound healing time and length of stay in the DPWC group were shorter than those in the CPWC group (P < .05). Furthermore, cases of wound infection within 30 days in the DPWC group were also less than that in the CPWC group (P < .05). However, no difference was found between the incisional negative pressure wound therapy assisted group (NPA group) and non- incisional negative pressure wound therapy assisted group (non-NPA group). During this study, hypoalbuminemia, as an independent high-risk factor, impacted perineal wound healing. (P = .0271) In conclusion, DPWC is a new surgical approach, which can lead to a better outcome than DPWC, and it can be another surgical procedure for clinicians. In addition, hypoalbuminemia should be interfered for avoiding perineal wound complications.

RATIONALE: Among the various forms of colorectal carcinomas, primary signet ring cell carcinoma (SRCC) of rectum is infrequent. Primary SRCC with adenoma is even rarer. Due to its low morbidity and lack of obvious manifestations at early stages, it is difficult to make an early diagnosis and perform surgical intervention in time. Herein, we reported a case of primary SRCC with tubular adenoma of rectum and also performed a review of the literature of such cases, in hopes of expanding the general understanding regarding such cases. PATIENT CONCERNS: A 61-year-old male patient presented with rectal bleeding for 1 week. DIAGNOSES: A neoplasm could be palpated through a rectal examination, with a size of 4.0 cm by 3.0 cm, at a distance of 5 cm from the anal edge. Magnetic resonance imaging examination and colonoscopies were performed to confirm the finding, and 4 tissue specimens were obtained for histopathologic biopsy. The result of biopsy was high-grade intraepithelial neoplasia with an adenoma component. INTERVENTIONS: Surgical resection was performed, and histopathologic and immunohistochemical staining examination of the resection confirmed the diagnosis of SRCC with tubular adenoma. OUTCOMES: The patient was discharged from hospital 12 days postsurgery, without any complications. Further chemotherapy and supportive treatments were suggested to him and will be followed at a local hospital. LESSONS: Primary rectal SRCC has a rather low morbidity. Furthermore, a rectal SRCC with adenoma which was presenting in this case is even more rare. Besides lack of clinical characters, delay of diagnosis and treatment frequently occur. So far, a surgical procedure has still been one of the most effective treatments. Considering of metastasis and the poor prognosis, early diagnosis, in-time radical resection, and a comprehensive followed treatment are recommended for a higher 5-year overall survival.

The objective of this paper is to demonstrate, considering the experiences from Chinese people, if slow transit constipation (STC) can be accurately diagnosed, choosing patients qualifying for surgery, subtotal colectomy with antiperistaltic cecosigmoidal anastomosis (STC-Anti-CSA) may come with more acceptable short and long-term outcomes.A retrospective study was performed at a department of colorectal and anal surgery. A cohort of 29 patients were coming with up to 5 years' follow-up care, who were in a diverse range of age, BMI, laxative medicine histories, including both males and females. Pre-surgery work-up strictly followed a protocol designed to rule out the patients who were not suitable for surgery treatments. Classification of STC was followed after diagnosis. STC-Anti-CSA was performed in all cases. The operative time, blood loss, average post-operative length of stay (LOS), frequency of BMs, stool consistency and patients satisfaction, by using Wexner constipation score (WCS), numerical rating scale (NRS), and abdominal bloating score (ABS), over the study period were recorded.In this study, there were 14 males and 15 females, with mean age 51, and BMI from 20.14 to 31.62 kg/m. The period of laxative medicine history was 4.8 years (2-13 years). The mean operative time was 152 ±â€Š34 min, and the mean perioperative blood loss was 123 ±â€Š51 mL. Average post-operative LOS (LOS) was 8 days. There were no severe post-operative complications, peri-operative mortality, anastomotic leaks, or revisions of the original surgery. Initial post-operative BMs averaged 6 times/day. During the period of 1 month to 12 months follow-up care, BMs fell down to 2 or 3 times/day. By the 1st to 3rd year follow-up care, BMs averaged 5 to 7 times/week. However, from the 4th year to 5th year, constipations recurred somehow. However, most patients were satisfied with their bowel patterns.STC-Anti-CSA can receive acceptable postoperative outcomes as long as the patients can be accurately diagnosed and classified as severe STC. Among the surgical procedures for STC, this procedure may be another suitable option, especially for Chinese people.

Sacrococcygeal pilonidal sinus is one of common diseases in general department. However, it is characterised, for surgeons, by high post-surgical recurrence and high incidence of post-surgical wound complications. Due to that fact, this retrospective randomised clinical study was designed to evaluate the surgical procedure effect of Z-plasty (ZP), compared with convention simple excision (SE). A total of 67 patients from May 2015 to May 2019 in our department were studied into two groups randomly, the group of ZP and the group of SE. The patients' characteristics, surgical data, hospital length of stay (LOS), and post-surgery complications were recorded. Statistical approaches were proceed with P-value analysis. The results are as follows. No significant differences were found between these two groups of the ages, gender distribution, Body Mass Index (BMI), smoking history, diabetes mellitus, and blood hypertension. The estimated blood loss, specimen volume, distance to anus, and drain output on the first day of post-surgery between the two groups were not statistically significant, either. However, surgical time in the ZP group was longer than that in the SE group (P < .0001). LOS in the ZP group was obviously shorter than that in the SE group (P = .0051). Furthermore, the patients of the ZP group were tending to suffer from fewer post-surgical complications than the ones of the SE group. In a conclusion, we hold the point view that the surgical procedure of ZP can lead a better outcome than SE because it demonstrated shortened LOS and fewer post-surgical complications.
