Background Double-stapled ileal pouch-anal anastomosis (DS-IPAA) is easy to construct and has a good functional outcome in patients with ulcerative colitis (UC). However, retention of the anorectal mucosa may lead to a subsequent risk of inflammation and neoplasia. This study aimed to identify factors associated with the retention of a large amount of anorectal mucosa after DS-IPAA. Methods The medical records of 163 patients who had undergone one-stage total proctocolectomy and DS-IPAA for UC between 2007 and 2020 were retrospectively reviewed. The patients were divided into two groups according to the length of the retained mucosa. The high anastomosis group was defined as having a retained mucosal length of ≥ 30 mm in the anterior or posterior wall. Clinical factors were compared between the high and low anastomosis groups. Results The high anastomosis group showed a significantly higher body mass index (BMI) (high vs. low: 23.2 vs. 19.0), longer operation time (304 vs. 263) and greater blood loss (357 vs. 240). In the multivariate analysis, high BMI was the only factor significantly associated with high anastomosis (odds ratio 1.32). There was a positive correlation between BMI and the length of the retained mucosa. Conclusions In DS-IPAA, BMI showed the strongest association with the retention of a large amount of the anorectal mucosa. In high BMI patients, although the risk of inability of anastomosis is little than that of IPAA with mucosectomy, the possible retention of a large amount of mucosa should be considered.

Why inflammation is common in ileal pouches with ulcerative colitis (UC) is unclear. We therefore clarified the morphological changes in pouches and afferent limbs (AL) of patients with UC and explored the relationship between these findings. We evaluated the morphological findings (histological and endoscopic inflammation as the Pouchitis Disease Activity Index [PDAI] histology subscore [hPDAI] and endoscopy subscore [ePDAI], inflammatory bowel disease [IBD]-specific findings using the IBD score [SIBD], colonic metaplasia using the colonic metaplasia score [CMS], and goblet cell [GC] ratio) in the pouch and AL of patients with UC. A total of 261 pouchoscopies were analyzed. The pouch body had a higher hPDAI (p IBD (p p p p IBD (Spearman’s coefficient r = 0.538; p p p p p = 0.107). The incidence of histological inflammation was higher in specimens showing basal plasmacytosis with severe mononuclear cell infiltration (BP) than in those without BP (odds ratio [OR] 6.790, p p p

The present study explored preoperative risk factors (predictors) of incisional surgical site infection (I-SSI) in severe or intractable ulcerative colitis (UC). This was a retrospective study of 230 consecutive patients who underwent primary surgery for UC. Patients whose surgical indications were UC with cancer or dysplasia were excluded. SSI was defined as an infection according to the Centers for Disease Control and Prevention Guidelines. Preoperative variables were examined by univariate, receiver operating characteristic curve, and multivariate analyses. We analyzed 208 patients in this study. In a multivariate logistic analysis, C-reactive protein (CRP) ≥ 1.7 mg/dl [odds ratio (OR) 5.35; 95% confidence interval (CI) 1.50–19.06; p = 0.01), albumin ≤ 2.4 g/dl (OR 5.77; 95% CI 1.41–23.57; p = 0.02), and preoperative blood transfusion (OR 3.21; 95% CI 1.04–9.96; p = 0.04) were predictors of I-SSI. Patients with all predictors had a more than 50% incidence of I-SSI, a higher incidence of all severe complications (13.6% vs. 3.2%; p = 0.02), and a longer postoperative hospital stay (19.5 vs. 17.0 days, p = 0.04) than the other patients. CRP ≥ 1.7 mg/dl, albumin ≤ 2.4 g/dl, and transfusion are predictors of I-SSI in severe or intractable UC. Clinician should carefully evaluate the surgical options before these predictors appear.

The present study evaluated the safety and efficacy of neoadjuvant chemotherapy with modified 5-fluorouracil, leucovorin, and oxaliplatin (mFOLFOX6) plus panitumumab in clinical stage III rectal cancer with KRAS wild-type. We conducted a prospective multicenter phase II trial. KRAS wild-type clinical stage III rectal cancer patients were enrolled. Patients received 6 cycles of mFOLFOX6 with 6 mg/kg panitumumab as neoadjuvant chemotherapy. The primary outcome was the response rate (RR) defined by RECIST. Lateral lymph node dissection (LLDN) was performed when patients had a locally advanced tumor

Highlights • The complication of percutaneous transhepatic gallbladder aspiration. • Inappropriate aspiration may cause an abdominal wall biloma. • We should consider alternative therapy when aspiration was not sufficiently., Background Abdominal wall biloma is an uncommon entity. We herein report an extremely rare case of cholecystitis with abdominal wall biloma after percutaneous transhepatic gallbladder aspiration (PTGBA). Presentation of case A 69-year-old woman was diagnosed with acute cholecystitis, and PTGBA was performed on Day 1. PTGBA was performed a second time because of re-expansion of the gallbladder and an increased CRP level on Day 3. Computed tomography was performed on Day 9 because we suspected recurrence of cholecystitis. It revealed a well-circumscribed fluid collection between the abdominal wall or the diaphragm and the liver. Based on these intraoperative findings, we diagnosed her with cholecystitis with abdominal wall biloma. Cholecystectomy and drainage of the abdominal wall biloma were performed on Day 10. The postoperative course was uneventful, and she was discharged on Day 18. Discussion Early cholecystectomy is the gold-standard treatment for acute cholecystitis, but cholecystectomy is not performed in some cases. PTGBA is much more convenient, quicker, and less costly, but inappropriate aspiration during the second PTGBA session might have spread the infected bile to the abdominal wall through the PTGBA route. Conclusion This case represents the first reported case of a biloma within the abdominal wall after PTGBA. To prevent this complication, we should aspirate gallbladder bile sufficiently during PTGBA. In addition, we should consider performing alternative therapy, such as percutaneous transhepatic gallbladder drainage or an operation, when we fail to appropriately aspirate.

The aim of this retrospective study was to evaluate the frequency and risk factors of urinary dysfunction after autonomic nerve-preserving surgery for rectal cancer. This was a retrospective multiinstitution study of 1002 rectal cancer patients conducted between January 2008 and December 2012 in Yokohama Clinical Oncology Group. Patients who had preoperative urinary dysfunction or had not undergone autonomic nerve preservation surgery were excluded. Urinary dysfunction was defined as that with a Clavien-Dindo classification grade ≥ 2. Patient-, tumor-, and surgery-related variables were examined by univariate and multivariate analyses. A total of 887 patients were analyzed. Postoperative urinary dysfunction was observed in 77 patients (8.8%). A multivariate logistic analysis showed that a tumor location in lower rectum (odds ratio [OR] 2.16; 95% confidence interval [CI] 1.15–3.71; p = 0.02), tumor diameter ≥ 40 mm (OR 2.07; 95% CI 1.19–4.44; p

Background/aim The present study examined the utility of serum p53 antibody (Ab) for detecting colitis-associated cancer (CAC) in the era of immunosuppressive therapy. Patients and methods Two hundred and fifty patients were analyzed, 219 had no carcinoma or dysplasia (Group non-CAC), and 31 had carcinoma or dysplasia (Group CAC). Serum p53 Abs were detected with an enzyme-linked immunosorbent assay. Immunohistochemical detection was performed in Group CAC. Results Immunosuppressive therapy was performed in 98.1% of Group non-CAC and 80.6% of Group CAC. There were no differences in serum p53 Abs positivity between Groups non-CAC and CAC (8.7% vs. 3.2%, p=0.30). p53 staining positivity was noted in 90.3% of Group CAC, and the rate of serum p53 positivity was significantly lower in patients with immunosuppressive therapy than in those without in Group CAC (0.0% vs. 16.7%, p=0.04). Conclusion The utility of serum p53 Ab for detecting CAC is dubious in the era of immunosuppressive therapy.

Background: Serum anti-p53 antibodies (Abs) have been considered useful for the early detection of ulcerative colitis-associated colorectal cancer (CAC). However, since the spread of immunosuppressive therapy for ulcerative colitis (UC) treatment in the 2010s, we have experienced a low prevalence of anti-p53 Abs in UC patients. The present study thus examined the utility of serum p53 Abs for detecting CAC in the era of immunosuppressive therapy. Methods: A series of 320 consecutive surgical cases of UC patients between April 2008 and March 2019 were enrolled in this study. Patients with no serum anti-p53 Abs data were excluded. Of the 250 patients analyzed, 219 had no carcinoma or dysplasia (Group non-CAC), and 31 had carcinoma or dysplasia (Group CAC). Serum anti-p53 Abs were detected with an enzyme-linked immunosorbent assay. Immnohistochemical detection was performed in Group CAC. Immunosuppressive therapy included a history of medication with prednisolone >20 mg/day, immunosuppressant drugs, immunomodulator drugs or biologic therapies for UC. Results: Immunosuppressive therapy was performed in 98.1% of Group non-CAC and 80.6% of Group CAC. There were no marked differences in serum anti-p53 Abs positivity between Groups non-CAC and CAC (8.7% vs. 3.2%, p =0.30). p53 staining positivity was noted in 90.3% of Group CAC, and the rate of serum p53 positivity was significantly lower in patients with immunosuppressive therapy than in those without in Group CAC (0.0% vs. 16.7%, p =0.04). Conclusions: The utility of serum p53 Abs for detecting CAC is dubious in the era of immunosuppressive therapy.

The safety and efficacy of laparoscopic surgery for transverse and descending colon cancer remain controversial. This study aimed to evaluate the short- and long-term outcomes of this procedure. We conducted a single-institutional randomized controlled trial. Patients with transverse or descending colon cancer were randomly allocated to receive laparoscopic surgery (LAC) or conventional open surgery (OC). The primary endpoint was the overall complication rate between the two groups. The secondary endpoints were the length of the postoperative hospital stay, the health-related quality of life (HRQOL) score (at 1, 6, and 12 months after surgery), the 5-year relapse-free survival (RFS), and the 5-year overall survival (OS). Between August 2008 and October 2012, a total of 66 patients were enrolled (33 in the LAC group and 33 in the OC group). The patient characteristics showed no significant differences between the two groups. The complication rates (≥ grade 3) were 6.1% in the LAC group and 12.1% in the OC group (p = 0.392). The length of postoperative stay was not significantly different between the two groups. Regarding the HRQOL, the physical functioning, role physical, bodily pain, social functioning, mental health, and role component summary at 1 month after surgery and the social functioning and mental health at 6 months after surgery were better in the LAC group than in the OC group. The 5-year RFS and OS rates were similar between the LAC and OC groups (RFS 90.5% and 87.3%, respectively, p = 0.752; OS 93.3% and 100.0%, respectively, p = 0.543). The short- and long-term outcomes of laparoscopic surgery for transverse and descending colon cancer are almost equal to those of open surgery. Laparoscopic resection is a better choice than open surgery for managing this cancer with regard to the short- and mid-term QOL. ClinicalTrials.gov Identifier: NCT01861691 .
