Surgical resection for small bowel obstruction due to right ovarian metastasis after ileocecal resection for cecal cancer: A case report

Although oophorectomy for ovarian metastasis from colorectal cancer is encouraged to improve the prognosis, that is also performed to relieve the symptom such as abdominal distention. We report a surgical case of intestinal obstruction due to ovarian metastasis after ileocecal resection for cecal cancer diagnosed at 77 years old.

Indications, postoperative management, and long-term prognosis of Crohn’s disease after ileocecal resection: a multicentre study comparing the East and West

Background Crohn’s disease (CD) phenotype differs between Asian and Western countries and may affect disease management, including decisions on surgery. This study aimed to compare the indications, postoperative management, and long-term prognosis after ileocecal resection (ICR) in Hong Kong (HK) and The Netherlands (NL). Methods CD patients with primary ICR between 2000 and 2019 were included. The endpoints were endoscopic (Rutgeerts’ score ≥i2b and/or radiologic recurrence), clinical (start or switch of IBD medication) and surgical recurrences. Cumulative incidences of recurrence were estimated with a Bayesian multivariable proportional hazards model. Results Eighty HK and 822 NL patients were included. The most common indication for ICR was penetrating disease (HK 32.5%, NL 22.5%) in HK versus stricturing disease (HK 32.5%, NL 48.8%) in NL (P<0.001). Postoperative prophylaxis was prescribed to 65 (81.3%) HK (28 [35.0%] amino salicylates [5-ASA]; 30 [37.5%] immunomodulators [IM]; 0 biologicals) versus 388 (47.1%) NL patients (67 [8.2%] 5-ASA; 187 [22.8%] IM; 69 [8.4%] biologicals; 50 [6.1%] combination therapy, P<0.001). Endoscopic or radiologic evaluation within 18 months was performed in 36.3% HK versus 64.1% NL (P< 0.001) patients. No differences between both populations were observed for endoscopic (hazard ratio [HR]: 0.53 (95% confidence interval [CI]: 0.24–1.21), clinical (HR: 0.91 (95% CI: 0.62–1.32), or surgical (HR: 0.61 (95% CI: 0.31–1.13)) recurrence risks. Conclusion The main indication for ICR in CD patients is penetrating disease in HK patients and stricturing disease in NL patients. Although considerable pre- and post-operative management differences were observed between the two geographical areas, the long-term prognosis after ICR is similar.

The management of appendicular abscesses in a Tunisian Tertiary Care Hospital

Background This study aims to describe the epidemiological, clinical, and radiological features of appendicular abscesses, compare the different approaches, and assess the safety and utility of laparoscopy in its management. Methods This descriptive retrospective study was carried out over 3 years extending from January 2017 to December 2019, reporting 150 appendicular abscesses cases. Data were collected from the register of the general surgery department B of the Rabta hospital. Cases with appendicular abscess were included. Files concerning patients with early appendicitis, non-appendicular abscesses or generalized appendicular peritonitis were excluded. Data were analysed with Statistical Package for the Social Sciences (SPSS) software. In univariate analysis, we used the chi2 test, the Fischer test, the Student t test. The factors retained by the univariate analysis were introduced into a logistic regression model. The significance level was set to 0.05. Results The mean age was 40.51 years. The gender ratio in patients with appendicular abscesses was M:F 1.94:1. Pain in the right iliac fossa associated with fever was the most common symptom (78% of cases). Clinical examination showed tenderness in the right iliac fossa in 38% of cases, rebound and guarding were found in 77 patients (51.3%), and a palpable mass was noted in 4 cases (4.2%). Imaging was done to confirm diagnosis; 46 patients underwent ultrasonogram and this confirmed the diagnosis in 26 patients (56%), while among the 71 patients who underwent CT abdomen confirmatory diagnosis was made in 65 patients (91.55%). An appendectomy was performed in 148 patients (98.6%) via laparoscopic approach in 94 patients, open Mac burney procedure in 32 cases (21.3%) and midline incision in 24 cases (16%). Two patients had an ileocecal resection. The appendix was most commonly located retrocecally (55.3%) in our cohort. The laparoscopic approach was performed in 94 patients (62.6%), and we had to convert in 44 patients due to dissection difficulties (46.8%). Among patients who underwent laparascopic approach 7 had developed peritonitis.. There were only 2 deaths. The mortality rate was 0,013%. The median duration of outpatient followup was 6 months (4–24 weeks) and was uneventful. Conclusion Appendicular abscess is a disease of young adults more common in men. Location of the appendix in our case series was mostly retroceacal. Laparoscopy was associated with good outcomes; peritonitis was uncommon and mortality was rare. The laparoscopic approach is a safe surgical technique for treating appendicular abscess and it can be considered as the routine approach for this condition In developing countries with limited technical resources, laparoscopy guarantees the absence of recurrence, reduces healthcare costs and decreases the risk of treating a severe disease conservatively.

P009 BEYOND TANAKA INDEX: PREOPERATIVE ASSESSMENT WITH 3D TECHNOLOGY IN LARGE HERNIAS WITH LOSS OF DOMAIN

Aim “Demonstrate step by step the planning that was carried out using 3D technology in pre-surgical assessment for complex hernia.” Material and Methods “57-year-old female, surgical record of laparoscopic uterine myomectomy 20 years ago, has an eventration with loss of domain on the left flank and a giant uterine myoma. A multidisciplinary assessment was carried out for surgical decision, myomectomy was rejected. Presurgical preparation was decided with progressive pneumoperitoneum (PPP) technique (1 week before surgery) associated with botulinum toxin (4 weeks before surgery). The patient specific volumes of the abdominal cavity and the eventration were measured with 3D technology resulting in a volume ratio (VR) of 34% pre-PPP, VR post-PPP and botulinum toxin was 9,8%. We compared these results to Tanaka index and we found a significant difference between the two techniques.” Results “During surgical intervention, multiple tumors were evidenced in the hernia content, distal ileum, cecum and omentum, peroperative pathological anatomy reported leiomyomas. An ileocecal resection+Omentectomy+TAR was performed. Patient was discharged on the 5th day without incidents. A definitive diagnosis of Diffuse Peritoneal Leiomyomatosis was made.” Conclusions “3D technology might represent a better tool to calculate intraabdominal and hernia volume, providing greater safety for the patient and the surgeon to avoid compartment syndrome. We found a significant difference between volumes measurements between Tanaka index and 3D technology. 3D technology gives us an unprecedented perspective for surgical planning in complex abdominal wall surgery The use of PPP and botulinum toxin is a safe and reproducible technique for hernia with loss of domain.”

Sporadic intra-abdominal desmoid tumor with a very unusual onset: two case reports

Background Intra-abdominal desmoid tumors are rare soft tissue tumors that arise mainly in the mesentery and pelvis. Their etiology may include genetic mutations, estrogen-associated changes after childbirth, and mechanical factors such as a history of abdominal surgery. However, there are cases of intra-abdominal desmoid tumors that develop in the absence of such causes. Since they are rare, diagnosis is often difficult based on clinical findings. We encountered two cases of patients with sporadic intra-abdominal desmoid tumors with a very unusual onset and contrasting features. Case presentation The first patient was a 51-year-old asian man who presented with sudden onset of abdominal pain. He was referred to our department because of a giant tumor detected on abdominal ultrasonography. Imaging revealed a 19-cm tumor with internal tumoral hemorrhage; however, no definitive diagnosis was made. Tumor resection was performed for diagnostic and therapeutic purposes. The second patient was a 41-year-old asian man, and right hydronephrosis was detected on abdominal ultrasonography during a periodic medical checkup. We diagnosed invasion of the primary mesenteric tumor into the right ureter using diagnostic imaging and performed ileocecal resection with partial right ureteral resection for a definitive diagnosis and therapeutic purposes. Although the tumors of both patients had developed from the ileal mesentery, the tumors were substantially different from each other based on their imaging findings, macroscopic morphology, and progression pattern. Meanwhile, they showed similar pathological characteristics. Both consisted of bundles of collagen fibrils of spindle-shaped fibroblasts with low cell atypia. Moreover, they were diagnosed as desmoid tumors using positive immunohistochemical staining for β-catenin. Conclusions Neither patient had susceptibility factors for desmoid tumors, and to our knowledge, there have been very few reports to date of intra-abdominal desmoid tumors that were diagnosed because of acute abdominal pain caused by tumoral hemorrhage or asymptomatic obstructive uropathy. Furthermore, it is clinically interesting that the two patients showed contrasting progression patterns and imaging findings. Intra-abdominal desmoid tumors are rare and may present with various symptoms and findings similar to those observed in our patients. Diagnosis therefore requires experience and knowledge that is not bound by preconceptions.

The Effect of Phenotype and Genotype on the Plasma Proteome in Patients with Inflammatory Bowel Disease

Background and Aims Protein profiling in patients with inflammatory bowel diseases (IBD) for diagnostic and therapeutic purposes is underexplored in IBD. This study analysed the association between phenotype, genotype and the plasma proteome in IBD. Methods Ninety-two (92) inflammation-related proteins were quantified in plasma of 1,028 patients with IBD (567 Crohn’s disease [CD]; 461 ulcerative colitis [UC]) and 148 healthy individuals to assess protein-phenotype associations. Corresponding whole-exome sequencing and global screening array data of 919 patients with IBD were included to analyse the effect of genetics on protein levels (protein quantitative trait loci (pQTL) analysis). Intestinal mucosal RNA sequencing and fecal metagenomic data were used for complementary analyses. Results Thirty-two (32) proteins were differentially abundant between IBD and healthy individuals, of which 22 proteins independent of active inflammation. Sixty-nine (69) proteins were associated with 15 demographic and clinical factors. Fibroblast growth factor-19 levels were decreased in CD patients with ileal disease or a history of ileocecal resection. Thirteen novel cis-pQTLs were identified and 10 replicated from previous studies. One trans-pQTL of the fucosyltransferase 2 (FUT2) gene (rs602662) and two independent cis-pQTLs of C-C motif chemokine 25 (CCL25) affected plasma CCL25 levels. Intestinal gene expression data revealed an overlapping cis-expression (e)QTL-variant (rs3745387) of the CCL25 gene. The FUT2 rs602662 trans-pQTL was associated with reduced abundances of fecal butyrate-producing bacteria. Conclusions This study shows that genotype and multiple disease phenotypes strongly associate with the plasma inflammatory proteome in IBD and identifies disease-associated pathways that may help to improve disease management in the future.

Timing of Tributyrin Supplementation Differentially Modulates Gastrointestinal Inflammation and Gut Microbial Recolonization Following Murine Ileocecal Resection

Background: Gastrointestinal surgery imparts dramatic and lasting imbalances, or dysbiosis, to the composition of finely tuned microbial ecosystems. The aim of the present study was to use a mouse ileocecal resection (ICR) model to determine if tributyrin (TBT) supplementation could prevent the onset of microbial dysbiosis or alternatively enhance the recovery of the gut microbiota and reduce gastrointestinal inflammation. Methods: Male wild-type (129 s1/SvlmJ) mice aged 8–15 weeks were separated into single cages and randomized 1:1:1:1 to each of the four experimental groups: control (CTR), preoperative TBT supplementation (PRE), postoperative TBT supplementation (POS), and combined pre- and postoperative supplementation (TOT). ICR was performed one week from baseline assessment with mice assessed at 1, 2, 3, and 4 weeks postoperatively. Primary outcomes included evaluating changes to gut microbial communities occurring from ICR to 4 weeks. Results: A total of 34 mice that underwent ICR (CTR n = 9; PRE n = 10; POS n = 9; TOT n = 6) and reached the primary endpoint were included in the analysis. Postoperative TBT supplementation was associated with an increased recolonization and abundance of anaerobic taxa including Bacteroides thetaiotomicorn, Bacteroides caecimuris, Parabacteroides distasonis, and Clostridia. The microbial recolonization of PRE mice was characterized by a bloom of aerotolerant organisms including Staphylococcus, Lactobacillus, Enteroccaceae, and Peptostreptococcacea. PRE mice had a trend towards decreased ileal inflammation as evidenced by decreased levels of IL-1β (p = 0.09), IL-6 (p = 0.03), and TNF-α (p < 0.05) compared with mice receiving TBT postoperatively. In contrast, POS mice had trends towards reduced colonic inflammation demonstrated by decreased levels of IL-6 (p = 0.07) and TNF-α (p = 0.07). These changes occurred in the absence of changes to fecal short-chain fatty acid concentrations or histologic injury scoring. Conclusions: Taken together, the results of our work demonstrate that the timing of tributyrin supplementation differentially modulates gastrointestinal inflammation and gut microbial recolonization following murine ICR.
