Autoimmunity Features in Patients With Non-Celiac Wheat Sensitivity.

INTRODUCTION: Nonceliac wheat sensitivity (NCWS) is characterized by intestinal and extraintestinal manifestations consequent to wheat ingestion in subjects without celiac disease and wheat allergy. Few studies investigated the relationship between NCWS and autoimmunity. The aim of this study is to evaluate the frequency of autoimmune diseases (ADs) and autoantibodies in patients with NCWS. METHODS: Ninety-one patients (13 men and 78 women; mean age of 40.9 years) with NCWS, recruited in a single center, were included. Seventy-six healthy blood donors (HBD) and 55 patients with a diagnosis of irritable bowel syndrome (IBS) unrelated to NCWS served as controls. Autoantibodies levels were measured. Human leukocyte antigen haplotypes were determined, and duodenal histology performed in all patients carrying the DQ2/DQ8 haplotypes. Participants completed a questionnaire, and their medical records were reviewed to identify those with ADs. RESULTS: Twenty-three patients with NCWS (25.3%) presented with ADs; autoimmune thyroiditis (16 patients, 17.6%) was the most frequent. The frequency of ADs was higher in patients with NCWS than in HBD (P = 0.002) and in patients with IBS (P = 0.05). In the NCWS group, antinuclear antibodies tested positive in 71.4% vs HBD 19.7%, and vs patients with IBS 21.8% (P < 0.0001 for both). The frequency of extractable nuclear antigen antibody (ENA) positivity was significantly higher in patients with NCWS (21.9%) than in HBD (0%) and patients with IBS (3.6%) (P = 0.0001 and P = 0.004, respectively). Among the patients with NCWS, 9.9% tested positive for antithyroglobulin, 16.5% for antithyroid peroxidase, and 14.3% for antiparietal cell antibodies; frequencies were not statistically different from controls. The presence of ADs was related to older age at NCWS diagnosis, female sex, duodenal lymphocytosis, and eosinophil infiltration. DISCUSSION: One in 4 patients with NCWS suffered from AD, and serum antinuclear antibodies were positive in a very high percentage of cases. These data led us to consider NCWS to be associated to ADs.

Safety and effectiveness of saving sphincter procedure in the treatment of chronic anal fissure in female patients.

INTRODUCTION: Lateral internal sphincterotomy (LIS) is still the approach of choice for the treatment of chronic anal fissure (CAF) regardless to the internal anal sphincter tone but it is burdened by high risk post-operative faecal incontinence (FI). In female patient there are some anatomical and functional differences of the sphinteric system which make them more at risk of FI and vaginal birth could cause sphinteric lesions affecting the anal continence function. The aim of our study is to evaluate the results of saving sphincter procedure as treatment for female patients affected by CAF. METHODS: We studied 110 female patients affected by CAF undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement associating pharmacological sphincterotomy in patients with hypertonic IAS. The follow up was at least for 2 years. The goals were patient's complete healing, the evaluation of FI, recurrence rate and manometry parameters. RESULTS: All wounds healed within 40 days after surgery. We recorded 8 cases of recurrences 6 healed with medical therapy and 2 with dilatation. We recorded 2 "de novo" temporary and low grade post-operative cases of FI. Post-operative value of MRP were unmodified in patient with normotonic IAS but significantly lower at 12 months follow up as compared with the pre-operative ones in patients with hypertonic IAS; after 24 months from surgery MRP values were within the normal range. CONCLUSION: The fissurectomy and anoplasty with V-Y cutaneous flap alone or in association with a pharmacological sphincterotomy in patients with hypertonic IAS may represent an effective approach for the treatment of CAF in female patients.

TNF-α, IL-17, and IL-22 production in the rectal mucosa of nonceliac wheat sensitivity patients: role of adaptive immunity.

In recent years, a new gluten- or wheat-related disease has emerged, a condition labeled "nonceliac gluten sensitivity" (NCGS) or "nonceliac wheat sensitivity" (NCWS). NCWS pathogenesis is still uncertain and attributed to very different mechanisms. We aimed to study the different T-lymphocyte subsets in the rectal mucosa of NCWS patients to demonstrate the possible contribution of adaptative immune response. Twelve patients (11 women, 1 man, age range 23-61 yr, median 32 yr) with a definitive diagnosis of NCWS were recruited at random for the present study. They underwent rectal endoscopy with multiple mucosal biopsies at the end of a double-blind placebo-controlled (DBPC) wheat challenge when they reported the reappearance of the symptoms. As controls we included 11 "healthy patients", sex- and age-matched with the patients who underwent colonoscopy evaluation for rectal bleeding due to hemorrhoids. Cells freshly obtained from rectal tissue were stained to detect anti-CD45, anti-CD3, anti-CD4, and anti-CD8. Furthermore, intracellular staining was performed with anti-tumor necrosis factor (TNF)-α, anti-interleukin (IL)-17, and anti-IL-22. Production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells, as well as of IL-17 by CD4+ cells, was higher in the rectal tissue of NCWS patients than in controls. On the contrary, IL-22 production by CD8+ cells was lower in NCWS patients than in the controls. In NCWS patients diagnosed by DBPC wheat challenge, there is a complex immunological activation, with a significant role for the adaptive response.NEW & NOTEWORTHY Nonceliac wheat sensitivity (NCWS) is a syndrome characterized by symptoms triggered by gluten intake. The pathogenesis is still uncertain. Studies have shown a role for innate immunity. We demonstrated that production of TNF-α by CD45+, CD3+, CD4+, and CD8+ cells and of IL-17 by CD4+ cells is higher in the rectal tissue of NCWS patients than in controls. We clearly demonstrated that in patients with NCWS there is a significant role for the adaptive response.

Effect of Fibrin Sealant on Seroma Formation Post-Incisional Hernia Repair.

Background: Development of seroma after incisional hernia repair is a common complication. Our study aims to compare the outcomes of sublay incisional hernia repairs with or without spray instillation of fibrin glue. Methods: We enrolled fifty patients undergoing incisional hernia repair. In all patients a suction drain was placed in the subcutaneous space. In one group (FG) 4 ml fibrin glue was instilled in the subcutaneous space. In the control group (C) patients did not receive any prevention measure. Wounds fluids were collected on post-operative day 1 (POD) and once daily until drain removal. All patients were followed up by ultrasound on POD 15, 20, 40, 60. Results: Drain fluid production, even if in significantly greater amount in the C group (p 0.01) as compared with the FG group, decreased after POD 1 in both groups. Drain was removed on POD-5 in 80% of FG patients and in 36% of C patients (p 0.01). No infective or bleeding complications were detected. In group FG average hospital stay was of 5.5 ÃÂ+- 2 days versus 7.1 +- 1.5 days in group C (p 0.01). At ultrasounds examination, seroma development was similar among two groups. Conclusions: Spray instillation of fibrin glue during the surgical repair reduces amount of drained fluid and hospital stay without increasing surgical complications. However, seroma occurrence was not significantly reduced.

Surgical Sphincter Saving Approach and Topical Nifedipine for Chronic Anal Fissure with Hypertonic Internal Anal Sphincter.

PURPOSE: The role of augmented internal anal sphincter (IAS) tone in the genesis of posterior chronic anal fissure (CAPF) is still unknown. Lateral internal sphincterotomy is the most employed surgical procedure, nevertheless it is burdened by high risk post-operative anal incontinence. The aim of our study is to evaluate results of sphincter saving procedure with post-operative pharmacological sphincterotomy for patients affected by CAPF with IAS hypertonia. Methods: We enrolled 30 patients, undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement; all patients received topical administration of nifedipine 0.3% and lidocaine 1.5% ointment-based therapy before and for 15 days after surgery. The primary goal was patient's complete healing and the evaluation of incontinence and recurrence rate; the secondary goal included the evaluation of manometry parameters, symptom relief and complications related to nifedipine and lidocaine administration. Results: All wounds healed within 40 days after surgery. We didn't observe any de novo postoperative anal incontinence case. We reported 2 cases of recurrences, healed after conservative therapy. We didn't report any local complications related to the administration of the ointment therapy; with whom all patients reported a good compliance. Conclusions: Fissurectomy and anoplasty with V-Y cutaneous advancement flap and topical administration of nifedipine and lidocaine, is an effective treatment for CAPF with IAS hypertonia.

Duodenal and Rectal Mucosa Inflammation in Patients With Non-celiac Wheat Sensitivity.

BACKGROUND & AIMS: Studies of non-celiac gluten or wheat sensitivity (NCGWS) have increased but there are no biomarkers of this disorder. We aimed to evaluate histologic features of colon and rectal tissues from patients with NCGWS. METHODS: We performed a prospective study of 78 patients (66 female; mean age, 36.4 years) diagnosed with NCGWS by double-blind wheat challenge at 2 tertiary care centers in Italy, from January 2015 through September 2016. Data were also collected from 55 patients wither either celiac disease or self-reported NCGWS but negative results from the wheat-challenge test (non-NCGWS controls). Duodenal and rectal biopsies were collected and analyzed by immunohistochemistry to quantify intra-epithelial CD3+ T cells, lamina propria CD45+ cells, CD4+ and CD8+ T cells, mast cells, and eosinophils and to determine the presence and size of lymphoid nodules in patients with NCGWS vs patients with celiac disease or non-NCGWS controls. RESULTS: Duodenal tissues from patients with NCGWS had significantly higher numbers of intra-epithelial CD3+ T cells, lamina propria CD45+ cells, and eosinophils than duodenal tissues from non-NCGWS controls. Duodenal tissues from patients with NCGWS and dyspepsia had a higher number of lamina propria eosinophils than patients with NCGWS without upper digestive tract symptoms. Rectal mucosa from patients with NCGWS had a larger number of enlarged lymphoid follicles, intra-epithelial CD3+ T cells, lamina propria CD45+ cells, and eosinophils than rectal mucosa from non-NCGWS controls. Duodenal and rectal mucosal tissues from patients with celiac disease had more immunocytes (CD45+ cells, CD3+ cells, and eosinophils) than tissues from patients with NCGWS or non-NCGWS controls. CONCLUSIONS: We identified markers of inflammation, including increased numbers of eosinophils, in duodenal and rectal mucosa from patients with NCGWS. NCGWS might therefore involve inflammation of the entire intestinal tract. Eosinophils could serve as a biomarker for NCGWS and be involved in its pathogenesis. Clinicaltrials.gov: NCT01762579.

Laparoscopic adrenalectomy: preoperative data, surgical technique and clinical outcomes.

BACKGROUND: laparoscopic adrenalectomy has become the standard treatment for adrenal lesions. The better clinical outcoms of laparoscopic technique are valid for treatment of small benign masses (< 5-6 cm), instead there are still open questions in literature regarding the correct management of larger lesions (> 6 cm) or in case of potentially malignant adrenal tumors. The aim of this study is to evaluate the outcomes of laparoscopic adrenalectomy in a referral surgical department for endocrine surgery. METHODS: at the University Hospital Policlinico "P. Giaccone" of Palermo between January 2010 and December 2017 we performed a total of 81 laparoscopic adrenalectomy. We created a retrospective database with analysis of patients data, morphologic and hormonal characteristics of adrenal lesions, surgical procedures and postoperative results with histological diagnosis and complications. RESULTS: Mean size of adrenal neoplasm was 7,5 cm (range 1.5 to 18 cm). The mean operative time was 145 min (range 75-240). In statistical analysis lenght of surgery was correlated to the lesion diameter (p < 0.05) but not with pre-operative features or histological results. 5 intraoperative complications occurred. Among these patients 4 presented bleeding and 1 a diaphagmatic lesion. No conversion to open surgery was necessary and no intraoperative blood transfusion were required. Mean estimated blood loss was 95 ml (range 50-350). There was no capsular disruption during adrenal dissection. Mean length of hospital stay was 3.7 days (range 3-6 days). CONCLUSIONS: Laparoscopic adrenalectomy is a safe procedure with low rate of morbidity. An accurate preoperative radiological examination is fundamental to obtain a stringent patients selection. The lesion diameter is related to longer operative time and appeares as the main predictive parameter of intraoperative complications but these results are not statistically significant. On the other side secreting adrenal tumors require more attention in operative management without increased rate of postoperative complications.

Persistence of Nonceliac Wheat Sensitivity, Based on Long-term Follow-up.

We investigated how many patients with a diagnosis of nonceliac wheat sensitivity (NCWS) still experienced wheat sensitivity after a median follow-up time of 99 months. We collected data from 200 participants from a previous study of NCWS, performed between July and December 2016 in Italy; 148 of these individuals were still on a strict wheat-free diet. In total, 175 patients (88%) improved (had fewer symptoms) after a diagnosis of NCWS; 145 of 148 patients who adhered strictly to a gluten-free diet (98%) had reduced symptoms, compared with 30 of 52 patients who did not adhere to a gluten-free diet (58%) (P < .0001). Of the 22 patients who repeated the double-blind, placebo-controlled challenge, 20 reacted to wheat. We conclude that NCWS is a persistent condition. Clinicaltrials.gov registration number: NCT02823522.

High Proportions of People With Nonceliac Wheat Sensitivity Have Autoimmune Disease or Antinuclear Antibodies.

BACKGROUND & AIMS: There is much interest in wheat sensitivity among people without celiac disease (CD), but little is known about any risks associated with the condition. We evaluated the prevalence of autoimmune diseases (ADs) among patients with nonceliac wheat sensitivity (NCWS), and investigated whether they carry antinuclear antibodies (ANA). METHODS: We performed a retrospective study of 131 patients diagnosed with NCWS (121 female; mean age, 29.1 years) at 2 hospitals in Italy from January 2001 through June 2011. Data were also collected from 151 patients with CD or irritable bowel syndrome (IBS) (controls). Patient medical records were reviewed to identify those with ADs. We also performed a prospective study of 42 patients (38 female; mean age, 34 years) diagnosed with NCWS from July 2011 through March 2014 at 3 hospitals in Italy. One hundred age- and sex-matched subjects with CD or IBS served as controls. Serum samples were collected from all subjects and ANA levels were measured by immunofluorescence analysis. Participants completed a questionnaire and their medical records were reviewed to identify those with ADs. RESULTS: In the retrospective analysis, similar portions of subjects with NCWS (29%) and CD (29%) developed ADs (mainly Hashimoto's thyroiditis, 29 cases), compared with a smaller proportion of subjects with IBS (4%) (P < .001). In the prospective study, 24% of subjects with NCWS, 20% of subjects with CD, and 2% of subjects with IBS developed ADs (P < .001). In the retrospective study, serum samples tested positive for ANA in 46% of subjects with NCWS (median titer, 1:80), 24% of subjects with CD (P < .001), and 2% of subjects IBS (P < .001); in the prospective study, serum samples were positive for ANA in 28% of subjects with NCWS, 7.5% of subjects with CD (P = .02), and 6% of subjects with IBS (P = .005 vs patients with NCWS). ANA positivity was associated with the presence of the HLA DQ2/DQ8 haplotypes (P < .001). CONCLUSIONS: Higher proportions of patients with NCWS or CD develop autoimmune disorders, are ANA positive, and showed DQ2/DQ8 haplotypes compared with patients with IBS.

3D CT scan for perioperative identification of anatomical variations of lungs.

AIM: The aim of this study is to investigate anatomical lung variations and vascular patterns using volumetric 3D computed tomography (CT) representations. METHODS & RESULTS: We considered 24 major thoracic surgery performed in our ward. In these, we discovered some interesting anatomical variations of the main pulmonary fissures. These findings were not visible on the plain x-ray or during routine examination of a preoperative CT scan. After re-examination of 3D CT scan reconstruction the anatomical variations were detected. DISCUSSION: General thoracic surgeons must familiarize themselves with anatomical variations in lungs. 3D images may aid the general thoracic surgeon in performing safer surgeries. CONCLUSION: 3D CT scan should be performed before surgery if possible.

Retrospective analysis of management of ingested foreign bodies and food impactions in emergency endoscopic setting in adults.

BACKGROUND: Ingestion of foreign bodies and food impaction represent the second most common endoscopic emergency after bleeding. The aim of this paper is to report the management and the outcomes in 67 patients admitted for suspected ingestion of foreign body between December 2012 and December 2014. METHODS: This retrospective study was conducted at Palermo University Hospitals, Italy, over a 2-year period. We reviewed patients' database (age, sex, type of foreign body and its anatomical location, treatments, and outcomes as complications, success rates, and mortalities). RESULTS: Foreign bodies were found in all of our 67 patients. Almost all were found in the stomach and lower esophagus (77 %). The types of foreign body were very different, but they were chiefly meat boluses, fishbones or cartilages, button battery and dental prostheses. In all patients it was possible to endoscopically remove the foreign body. Complications related to the endoscopic procedure were unfrequent (about 7 %) and have been treated conservatively. 5.9 % of patients had previous esophageal or laryngeal surgery, and 8.9 % had an underlying esophageal disease, such as a narrowing, dismotility or achalasia. CONCLUSION: Our experience with foreign bodies and food impaction emphasizes the importance of endoscopic approach and removal, simple and secure when performed by experienced hands and under conscious sedation in most cases. High success rates, lower incidence of minor complications, reduction of the need of surgery and reduced hospitalization time are the strengths of the endoscopic approach.

Heat shock protein 60 levels in tissue and circulating exosomes in human large bowel cancer before and after ablative surgery.

BACKGROUND: Heat shock protein 60 (Hsp60) is a chaperonin involved in tumorigenesis, but its participation in tumor development and progression is not well understood and its value as a tumor biomarker has not been fully elucidated. In the current study, the authors presented evidence supporting the theory that Hsp60 has potential as a biomarker as well as a therapeutic target in patients with large bowel cancer. METHODS: The authors studied a population of 97 subjects, including patients and controls. Immunomorphology, Western blot analysis, and quantitative real-time polymerase chain reaction were performed on tissue specimens. Exosomes were isolated from blood and characterized by electron microscopy, biochemical tests, and Western blot analysis. RESULTS: Hsp60 was found to be increased in cancerous tissue, in which it was localized in the tumor cell plasma membrane, and in the interstitium associated with cells of the immune system, in which it was associated with exosomes liberated by tumor cells and, as such, circulated in the blood. An interesting finding was that these parameters returned to normal shortly after tumor removal. CONCLUSIONS: The data from the current study suggested that Hsp60 is a good candidate for theranostics applied to patients with large bowel carcinoma and encourage similar research among patients with other tumors in which Hsp60 has been implicated.

Thoracoscopy in pleural effusion--two techniques: awake single-access video-assisted thoracic surgery versus 2-ports video-assisted thoracic surgery under general anesthesia.

UNLABELLED: Awake single access video-assisted thoracic surgery with local anesthesia improves procedure tolerance, reduces postoperative stay and costs. MATERIALS & METHODS: Local anesthesia was made with lidocaine and ropivacaine. We realize one 20 mm incision for the 'single-access', and two incisions for the '2-trocars technique'. RESULTS: Mortality rate was 0% in both groups. Postoperative stay: 3 dd ± 4 versus 4 dd ± 5, mean operative time: 39 min versus 37 min (p < 0.05). Chest tube duration: 2dd ± 5 versus 3 dd ± 6. COMPLICATIONS: 11/95 versus 10/79. CONCLUSION: Awake technique reduce postoperative hospital stay and chest drainage duration, similar complications and recurrence rate. The authors can say that 'awake single-access VATS' is an optimal diagnostic and therapeutic tool for the management of pleural effusions, but above extends surgical indication to high-risk patients.

Risk of low bone mineral density and low body mass index in patients with non-celiac wheat-sensitivity: a prospective observation study.

BACKGROUND: Non-celiac gluten sensitivity (NCGS) or 'wheat sensitivity' (NCWS) is included in the spectrum of gluten-related disorders. No data are available on the prevalence of low bone mass density (BMD) in NCWS. Our study aims to evaluate the prevalence of low BMD in NCWS patients and search for correlations with other clinical characteristics. METHODS: This prospective observation study included 75 NCWS patients (63 women; median age 36 years) with irritable bowel syndrome (IBS)-like symptoms, 65 IBS and 50 celiac controls. Patients were recruited at two Internal Medicine Departments. Elimination diet and double-blind placebo controlled (DBPC) wheat challenge proved the NCWS diagnosis. All subjects underwent BMD assessment by Dual Energy X-Ray Absorptiometry (DXA), duodenal histology, HLA DQ typing, body mass index (BMI) evaluation and assessment for daily calcium intake. RESULTS: DBPC cow's milk proteins challenge showed that 30 of the 75 NCWS patients suffered from multiple food sensitivity. Osteopenia and osteoporosis frequency increased from IBS to NCWS and to celiac disease (CD) (P <0.0001). Thirty-five NCWS patients (46.6%) showed osteopenia or osteoporosis. Low BMD was related to low BMI and multiple food sensitivity. Values of daily dietary calcium intake in NCWS patients were significantly lower than in IBS controls. CONCLUSIONS: An elevated frequency of bone mass loss in NCWS patients was found; this was related to low BMI and was more frequent in patients with NCWS associated with other food sensitivity. A low daily intake of dietary calcium was observed in patients with NCWS.

A case of splenic rupture: a rare event after laparoscopic cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy (LC) is generally safe and well-accepted. In rare cases, it is associated with complications (intra- e postoperative bleeding, visceral injury and surgical site infection). Splenic lesion has been reported only after direct trauma. We report an unusual case of splenic rupture presenting after "uncomplicated" LC. CASE PRESENTATION: A 77-year-old woman presented with distended abdomen, tenderness in the left upper quadrant and severe anemia 12 hours after LC. Clinical examination revealed hypovolemic shock. Abdominal computed tomography confirmed the diagnosis of splenic rupture, and the patient required an urgent splenectomy through midline incision. The post-operative course was uneventful and the patient was discharged on 7th postoperative day.Splenic injury rarely complicates LC. We postulate that congenital or post-traumatic adhesions of the parietal peritoneum to the spleen may have been stretched from the splenic capsule during pneumoperitoneum establishment, resulting in subcapsular hematoma and subsequent delayed rupture. CONCLUSIONS: Splenic rupture is an unusual but life-threatening complication of LC. Direct visualization of the spleen at the end of LC might be a useful procedure to aid early recognition and management in such cases.

Surgical Management of Complicated Abdominal Tuberculosis: The First Systematic Review-New Treatments for an Ancient Disease and the State of the Art.

Background: Abdominal tuberculosis comprises all forms of tuberculosis that involve the gastrointestinal tract. Controversies exist regarding the surgical approach and timing and type of intervention for complicated forms of abdominal tuberculosis. The aim of this systematic review is to define the rate of surgical treatment, the type of surgical procedures performed and the role of minimally invasive surgery in the management of abdominal tuberculosis. Methods: The literature in MEDLINE, Scopus and Google Scholar and forward and backward citations for studies published between database inception and July 2022 were searched without language restrictions. All prospective and retrospective studies were included. The electronic database search yielded 2440 records. Additionally, eight records were identified through snowball searching. Following duplicate removal (45 duplicates found), 2403 records were screened for titles and abstracts. After screening for titles and abstracts and exclusion criteria, 38 reports were included for systematic review, 27 retrospective studies and 11 prospective studies. Data extracted included the general and demographic characteristics of the studies, diagnostic methods used, clinical presentation, site of involvement and details on surgical treatment. Results: In total, 2870 patients with a diagnosis of abdominal tuberculosis were included, and 1803 (63%) underwent a surgical procedure. The majority of patients underwent an open surgical procedure (95%). The most commonly performed procedures were adhesiolysis (21%) and small bowel resection with primary anastomosis (21%). Conclusions: The results of this review suggest that whenever surgery is required, there is a tendency to perform open surgical procedures in patients with complicated abdominal tuberculosis, both in emergency and elective settings, despite advances in minimally invasive surgery. The study protocol was registered on PROSPERO (CRD42022354322).

A rare presentation of gastric phytobezoar: Simultaneous bleeding and perforation. combined laparoscopic and endoscopic approach. Report of a case.

INTRODUCTION: Bezoars are intraluminal conglomerates of indigestible foreign materials that accumulate in the gastrointestinal tract. We describe our experience with a patient with gastric perforation and concomitant gastric haemorrhage with severe anaemia, in whom we successfully extracted a giant gastric phytobezoar by cooperative laparoscopic and endoscopic surgery. CASE PRESENTATION: A 68-year-old man was admitted with melena and septic shock. CT scan revealed a gastric perforation. We performed a combined laparoscopic and endoscopic approach with gastrotomy, removal of the phytobezoar and laparoscopic gastric suture. The suture was examined for leakage with the endoscopic hydropneumatic test to obtain direct vision of the suture and no evidence of leakage by insufflation of the area. DISCUSSION: Gastric bezoars can be managed conservatively, endoscopically or surgically. Endoscopic removal, if effective, would be an attractive alternative for bezoar treatment. Usually endoscopic attempts are unsuccessful because of the large size of the bezoar and the difficulty in fragmentation. The laparoscopic approach for bezoar seems to have better postoperative outcomes. The main criticisms of the technique are abdominal spillage with risk of contamination as well as longer operative times. CONCLUSION: In our case we simultaneously performed laparoscopic surgery and endoscopic operative procedure in accordance with the principles of laparoscopic and endoscopic cooperative surgery to treat the gastric bezoar in order to overcome the limits of a single technique.

Altered Gut Microbic Flora and Haemorrhoids: Could They Have a Possible Relationship?

To date, the exact pathophysiology of haemorrhoids is poorly understood. The different philosophies on haemorrhoids aetiology may lead to different approaches of treatment. A pathogenic theory involving a correlation between altered anal canal microflora, local inflammation, and muscular dyssynergia is proposed through an extensive review of the literature. Since the middle of the twentieth century, three main theories exist: (1) the varicose vein theory, (2) the vascular hyperplasia theory, and (3) the concept of a sliding anal lining. These phenomena determine changes in the connective tissue (linked to inflammation), including loss of organization, muscular hypertrophy, fragmentation of the anal subepithelial muscle and the elastin component, and vascular changes, including abnormal venous dilatation and vascular thrombosis. Recent studies have reported a possible involvement of gut microbiota in gut motility alteration. Furthermore, dysbiosis seems to represent the leading cause of bowel mucosa inflammation in any intestinal district. The alteration of the gut microbioma in the anorectal district could be responsible for haemorrhoids and other anorectal disorders. A deeper knowledge of the gut microbiota in anorectal disorders lays the basis for unveiling the roles of these various gut microbiota components in anorectal disorder pathogenesis and being conductive to instructing future therapeutics. The therapeutic strategy of antibiotics, prebiotics, probiotics, and fecal microbiota transplantation will benefit the effective application of precision microbiome manipulation in anorectal disorders.

Bile leaks after videolaparoscopic cholecystectomy: duct of Luschka. Endoscopic treatment in a single centre and brief literature review on current management.

BACKGROUND: Laparoscopic cholecystectomy (LC) for gallstone disease is the most common surgical procedures performed in Western countries and bile leaks remain a significant cause of morbidity (0.2-2%). The bile ducts of Luschka (DL)are small ducts which originate from the right hepatic lobe, course along the gallbladder bed, and usually drain in the extrahepatic bile ducts. Injuries to these ducts are the second most frequent cause of bile leaks after cholecystectomy. Aim of our study is build a literature review starting from our experience. PERSONAL EXPERIENCE: Forty four patients with abdominal bile collections post-cholecystectomy by suspected bile leak under-went endoscopic retrograde cholagio-pancreatography (ERCP). A complete cholangiogram was obtained in 42 patients(95.5%). In according to the magnitude of bile leak daily, we subdivided the patients in two groups: a) < 180 ml/daily,and b) > 180 ml/daily. The most common site of the leak was the cystic duct stump (94.5%), followed by DL (2 patient = 5.5%). 10 Fr stent insertion after endoscopic sphincterotomy (ES) was the most common intervention. In 6 patients (14%) a 7 Fr naso-biliary drainage was inserted. On an intention-to-treat basis, endoscopic intervention at ERCP had 100% success rate for resolution of the leak. The median time for resolution of the leak was 8 and 12 days in the first and second group respectively. No mortality ERCP-related were recorded. Early minor complications occurred in 7/42 (16.5%) patients. METHODS: A literature search using MEDLINE's Medical Subject Heading terms was used to identify recent articles.Cross-references from these articles were also used. RESULTS: ERCP is the most common diagnostic and therapeutic method used in bile leaks post-cholecystectomy. Most patients with DL leaks are symptomatic, and most leaks are detected postoperatively during the first postoperative week. Reduction of intra-ductal pressure with ES and stent or naso-biliary tube insertion will lead to preferential flow of bile through the papilla, thus permitting DL injuries to heal. This is the most common treatment modality used. In a minority of patients,re-laparoscopy is performed. In such cases, the leaking DL is visualized directly and ligation usually is sufficient treatment.Simple drainage is adequate treatment for a small number of asymptomatic patients with low-volume leaks. CONCLUSIONS: DL leaks occur after cholecystectomy regardless of gallbladder pathology or urgency of operation. They have been encountered more frequently in the era of LC Intraoperative cholangiography does not detect all such leaks. ERCP with ES and stent placement are the most common effective diagnostic and therapeutic methods used. Intraoperative and perioperative adjunctive measures, such as fibrin glue instillation and pharmacologic relaxation of the sphincter of Oddi,can potentially be used in lowering the incidence and in the treatment of DL leaks.

Colorectal infiltrating deep endometriosis: Laparoscopic treatment. A case report.

Endometriosis is a disease affecting approximately 10% of women of fertile age. A particular presentation is deep infiltrating endometriosis of the rectosigmoid colon with symptoms that can mimic an intestinal obstruction or neoplasm. We report the case of a 39-year-old woman with pelvic pain during the menstrual cycle and significant anemia who presented an ectopic endometrial tissue in correspondence of the rectum. Because of the thickness of the lesion the patient underwent a segmental laparoscopic colorectal resection with end-to-end anastomosis.
