AIM
To retrospective review the laparoscopic management of Meckel Diverticulum (MD) in two Italian Pediatric Surgery Centers.
METHODS
Between January 2002 and December 2012, 19 trans-umbilical laparoscopic-assisted (TULA) procedures were performed for suspected MD. The children were hospitalized for gastrointestinal bleeding and/or recurrent abdominal pain. Median age at diagnosis was 5.4 years (range 6 mo-15 years). The study included 15 boys and 4 girls. All patients underwent clinical examination, routine laboratory tests, abdominal ultrasound and technetium-99m pertechnetate scan, and patients with bleeding underwent gastrointestinal endoscopy. The abdominal exploration was performed with a 10 mm operative laparoscope. Pneumoperitoneum was established based on the body weight. Systematic overview of the peritoneal cavity allowed the ileum to be grasped with an atraumatic instrument. The complete exploration and surgical treatment of MD were performed extracorporeally, after intestinal exteriorization through the umbilicus. All patients' demographics, main clinical features, diagnostic investigations, operative time, histopathology reports, conversion rate, hospital stay and complications were registered and analyzed.
RESULTS
MD was identified in 17 patients, while 1 had an ileal duplication and 1 a jejunal hemangioma. Fifteen patients had painless intestinal bleeding, while 4 had recurrent abdominal pain and exhibited cyst like structures in an ultrasound study. Eleven patients had a positive technetium-99m pertechnetate scan. In the patients with bleeding, gastrointestinal endoscopy did not name the source of hemorrhage. All patients were subjected to a TULA surgical procedure. An intestinal resection/anastomosis was performed in 14 patients, while 4 had a wedge resection of the diverticulum and 1 underwent stapling diverticulectomy. All surgical procedures were performed without conversion to open laparotomy. Mean operative time was 75 min (range 40-115 min). No major surgical complications were recorded. The median hospital stay was 5-7 d (range 4-13 d). All patients are asymptomatic at a median follow up of 4, 5 years (range 10 mo-10 years).
CONCLUSION
Trans-umbilical laparoscopic-assisted Meckel's diverticulectomy is safe and effective in the treatment of MD, with excellent results.

Cesarean section scar diverticulum (CSD) has become a formidable obstacle preventing women receiving CS from reproducing. However, the pathogenesis of CSD remains unexplored. In this study, we characterized the cervical microbiota, metabolome, and endometrial transcriptome of women with CSD. Based on the 16s rRNA results of cervical microbes, the microbial diversity in the CSD group was higher than that in the control group. were significantly decreased in the CSD group and were mutually exclusive with potentially harmful species (, and ) abnormally elevated in CSD. The microbiota in the CSD group exhibited low activity in carbohydrate metabolism and high activity in fatty acid metabolism, as confirmed by the metabolomic data. The metabolomic characterization identified 6,130 metabolites, of which 34 were significantly different between the two groups. In the CSD group, N-(3-hydroxy-eicosanoid)-homoserine lactone and Ternatin were significantly increased, in addition to the marked decrease in fatty acids due to high consumption. N-(3-hydroxy-eicosanoyl)-homoserine lactone is a regulator that promotes abnormal apoptosis in a variety of cells, including epithelial cells and vascular endothelial cells. This abnormal apoptosis of endometrial epithelial cells and neovascularization was also reflected in the transcriptome of the endometrium surrounding the CSD. In the endometrial transcriptome data, the upregulated genes in the CSD group were active in negatively regulating the proliferation of blood vessel endothelial cells, endothelial cells, and epithelial cells. This alteration in the host's endometrium is most likely influenced by the abnormal microbiota, which appears to be confirmed in the results by integrating host transcriptome and microbiome data. For the first time, this study described the abnormal activity characteristics of microbiota and the mechanism of host-microbiota interaction in CSD. Cesarean section scar diverticulum (CSD) has become a formidable obstacle preventing women receiving CS from reproducing. In this study, we revealed that potentially harmful microbes do have adverse effects on the host endometrium. The mechanism of these adverse effects includes the inhibition of the activity of beneficial bacteria such as lactobacilli, consumption of protective metabolites of the endometrium, and also the production of harmful metabolites. In the present study, we elucidated the mechanism from the perspectives of microbial, metabolic, and host responses, providing an important rationale to design preventive and therapeutic strategies for CSD.

Diverticulosis is frequently accompanied by altered bowel habits. The biogenic amines within colonic mucosa control bowel motility, and in particular, alterations in serotonin signaling may play a role in colon diverticulosis. The aim of the study was to assess the concentration of biogenic amines and serotonin receptor expression in the colonic mucosa in patients with diverticulosis and healthy controls. This prospective, comparative study included 59 individuals: 35 with sigmoid diverticulosis and 24 healthy controls. The study was held at the Department of Gastroenterology and Internal Medicine, Medical University of Warsaw, Poland. Mucosal samples were taken from the right and left colon during a colonoscopy in all patients. Concentrations of norepinephrine, 3-methoxy-4-hydroxyphenylglycol, dopamine, homovanillic acid, serotonin, and 5hydroxyindoleacetic acid were measured with high-performance liquid chromatography. Expressions of human 5-hydroxytryptamine receptor 3A, 5-hydroxytryptamine receptor 4, 5-hydroxytryptamine receptor 7, solute carrier family 6 member 4 (SERT) for serotonin, as well as the neuroglia activation markers glial fibrillary acidic protein, S100 calcium-binding protein B, and proteolipid protein 1, were assessed with polymerase chain reaction. The median age and sex distribution were comparable in both study groups (median 69 y vs. 52 y; < 0.455 and males/females in cases 11/17 vs. 18/19 in controls; < 0.309). In diverticulosis patients, there was a higher concentration of serotonin in the left affected colon compared to the right healthy part of the colon (median 8239 pg/mg vs. 6326 pg/mL; < 0.01). The expression was lower in the affected left segment compared to the right colon (median 0.88 vs. 1.36; < 0.01). There was a higher colonic mucosa concentration of serotonin (median 8239 pg/mg vs. 6000 pg/mL; < 0.02) and 5hydroxyindoleacetic acid/serotonin ratio (median 0.27 vs. 0.47; < 0.01) in diverticulosis patients compared to controls in the left side of the colon. The concentration of serotonin in the mucosa of the colon segment affected by diverticula is higher than in the healthy segment in the same individuals and higher than in healthy controls. These results underline serotonin signaling in colon diverticulosis pathophysiology.

A subaortic left ventricular diverticulum (SLVD) represents an extremely rare congenital anomaly. It can be asymptomatic but sometimes develops fatal complications. Treatment has been debated due to limited experience. We present the successful treatment of a giant SLVD with aortic regurgitation and stenosis and ascending aorta dilatation. Our goal is to improve understanding of this rare entity.

BACKGROUND
Juxta-papillary duodenal diverticulum (JPDD) has been associated with obstructive jaundice and ascending cholangitis. Potential mechanisms include periampullary colonization of pathogenic bacteria and mechanical obstruction. However, the relation of JPDD with pyogenic liver abscess (PLA) has not been reported. Moreover, approximately one third of patients with PLA have no identifiable risk factors and are labelled as "cryptogenic". We hypothesized that JPDD is an unidentified risk factor for cryptogenic PLA and the aim of this study was to examine this association.
METHODS
We conducted a retrospective chart review to identify cases of PLA (n = 66) and compare those to matched controls (n = 66). 66 patients met the study inclusion criteria of a diagnosis of PLA using computerized tomography (CT) imaging and either positive culture or confirmed resolution after antibiotic therapy. Patients with diagnoses of amebic liver abscess, traumatic liver abscess, post cholecystectomy liver abscess, concurrent acute cholecystitis, and hepatobiliary malignancy were excluded. Controls were identified from a radiology database and matched one-to-one with the cases by age and sex. Demographic and clinical data was extracted from electronic medical records. CT scan images of all cases and controls were reviewed by a single expert radiologist to identify the presence of JPDD. Statistical tests including Chi-square and t-test with multiple logistic regression were used to examine the group differences in JPDD and other factors.
RESULTS
Among 132 study samples, 13.6% (9/66) of the cases were found to have JPDD, compared to 3.0% (2/66) among controls (p = 0.03). This corresponded to an odds ratio (OR) of 5.05 [OR 5.05; CI 1.05-24.4] on multiple logistic regression analysis. In addition, 1/3rd of PLA cases with JPDD had no other traditional risk factors (cryptogenic PLA). However, a statistically significant association of JPDD with cryptogenic PLA could not be established possibly because of a small number of cases. We found significantly high rate of diabetes mellitus (DM) (42.4%; n = 28/66) among cases compared to controls (21.2%; n = 14/66; p = 0.01).
CONCLUSION
We found a significant association between JPDD and PLA. We need studies with larger sample sizes to confirm this relationship and to explore if JPDD could be related to cryptogenic liver abscesses.

To study the influencing factors of scar diverticulum formation and its monitoring methods, 141 people with a history of cesarean section and kidney deficiency and blood stasis were selected as subjects. The transvaginal ultrasound technique was used to divide the case into the scar diverticulum case group and the complete group, and the clinical situation was analyzed. Transvaginal three-dimensional ultrasound combined with HD flow pattern was used to analyze the morphology of uterus scar diverticulum and the parameters of peripheral muscle blood flow. The relationship between the size of scar diverticulum and its influencing factors, the location of the uterus and the number of cesarean sections were studied. Studies have found that retroposition of the uterus or the number of cross-cutting will increase the possibility of uterus scar diverticulum formation. Therefore, transvaginal three-dimensional ultrasound combined with HD flow mode can identify and diagnose scar diverticulum.

Review
AIM
To investigate the clinical presentation, diagnosis, and treatment of giant colonic diverticulum (GCD, by means of a complete and updated literature review). GCD is a rare manifestation of diverticular disease of the colon. Less than 200 studies on GCD were published in the literature, predominantly case reports or small patient series.
METHODS
A systematic review of the literature was performed using the Embase and PubMed databases to identify all the GCD studies. The following MESH search headings were used: "giant colonic diverticulum"; "giant sigmoid diverticulum". The "related articles" function was used to broaden the search, and all of the abstracts, studies, and citations were reviewed by two authors. The following outcomes were of interest: the disease and patient characteristics, study design, indications for surgery, type of operation, and post-operative outcomes. Additionally, a subgroup analysis of cases treated in the last 5 years was performed to show the current trends in the treatment of GCD. A GCD case in an elderly patient treated in our department by a sigmoidectomy with primary anastomosis and a diverting ileostomy is presented as a typical example of the disease.
RESULTS
In total, 166 GCD cases in 138 studies were identified in the literature. The most common clinical presentation was abdominal pain, which occurred in 69% of the cases. Among the physical signs, an abdominal mass was detected in 48% of the cases, whereas 20% of the patients presented with fever and 14% with abdominal tenderness. Diagnosis is based predominantly on abdominal computed tomography. The most frequent treatment was colic resection with en-bloc resection of the diverticulum, performed in 57.2% of cases, whereas Hartmann's procedure was followed in 11.4% of the cases and a diverticulectomy in 10.2%. An analysis of sixteen cases reported in the last 5 years showed that the majority of patients were treated with sigmoidectomy and en-bloc resection of the diverticulum; the postoperative mortality was null, morbidity was very low (1 patient was hospitalized in the intensive care unit for postoperative hypotension), and the patients were discharged 4-14 d after surgery.
CONCLUSION
Giant colonic diverticulum is a rare manifestation of diverticular diseases. Surgical treatment, consisting predominantly of colonic resection with en bloc resection of the diverticulum, is the preferred option for GCD and guarantees excellent results.

A 66-year-old male from Venezuela with history of high blood pressure and diverticulosis is being studied on an outpatient basis for abdominal pain and weight loss of several months of evolution. He presented to the emergency department due to worsening abdominal pain in the last 48 hours and fever. His abdomen was mildly tender to palpation in the left hypochondrium but did not exhibit signs of peritonitis. An abdominal x-ray was performed, revealing an oval, smooth-walled mass located in the left upper quadrant that contained a gas-fluid level. An outpatient abdominal CT scan performed two months earlier showed an intraabdominal, 14.8x10x16cm air cystic lesion, proposing giant colonic diverticulum as first diagnostic possibility. Given the findings of the abdominal x-ray, urgent abdominal CT was requested (image 3) with results suggestive of sigmoid-dependent giant diverticulum, complicated by probable superinfection and torsion of the sigma at its base. Considering the suspected diagnosis, the patient underwent diverticulectomy, demonstrating purulent content inside. Histopathology confirmed the diagnosis. Evolution after surgery was favourable and the patient was discharged on the sixth postoperative day.

Zenker's diverticulum is a rare and generally benign condition. Its occurrence in a hemodialysis patient has therapeutic and prognostic implications and is a risk factor for mortality and morbidity due to its complications, such as protein-energy malnutrition and pneumonitis. We here report a case of Zenker's diverticulum diagnosed in a chronic haemodialysis patient. The study involved a 61-year-old female patient admitted with upper gastrointestinal bleeding associated with dysphagia. Physical examination showed alteration of general condition and the patient reported an average weight loss of 5 kg in 3 months. Esophagogastroduodenal transit was characterized by dilatation of the cervical esophagus, appearing as a large heterogeneous niche whose upper pole was at the level of the pharyngoesophageal junction. The diagnosis of Zenker's diverticulum was retained. Diverticulectomy by cervical incision was performed. The patient died due to inhalational lung disease in the early postoperative period. Zenker diverticulum is a rare, generally benign disease, but in patients undergoing chronic haemodialysis, it increases mortality and morbidity.
