A 14-year-old girl with the mitochondrial neurogastrointestinal encephalopathy syndrome had an 8-year history of intestinal pseudoobstruction with abdominal pain, persistent vomiting, gastric and duodenal dilatation, and duodenal diverticulosis. The child appeared chronically malnourished and had severe growth failure. Multisystem involvement was evident with the presence of ptosis, external ophthalmoplegia, muscle wasting, peripheral neuropathy, and diffuse white matter disease seen on magnetic resonance imaging. Lactic acidosis and increased cerebrospinal fluid protein were observed. Mitochondrial enzyme analysis of fresh-frozen skeletal muscle revealed a respiratory chain defect. Molecular genetic studies showed multiple mitochondrial DNA deletions. Pathologic findings in the intestine included atrophy of the external layer of the muscularis propria and an increased number of abnormal-appearing mitochondria in ganglion and smooth-muscle cells. Microvesicular steatosis was observed in liver, skeletal, and gastrointestinal smooth muscle, and Schwann cells of peripheral nerve. Brightly eosinophilic inclusions in the cytoplasm of gastrointestinal ganglion cells were visible by light microscopy, which were confirmed to be megamitochondria by ultrastructural studies. This is the first report of abnormal mitochondria observed in intestinal ganglion and smooth-muscle cells in this syndrome.

A 38-year-old para 2 presented with the gradual onset of nausea vomiting and increasing left lower quadrant pain, at 33 weeks' gestation. She was known to have uterine leiomyomas, with ultrasonography depicting an 8-cm intramural fundal leiomyoma. In addition a left lateral nondiscrete 10 x 8-cm mass was depicted at the point of maximum tenderness. Magnetic resonance imaging (MRI) demonstrated diverticulosis of the descending and sigmoid colon. The patient remained afebrile and received repeated doses of intramuscular analgesics and was cleared by the surgical consultant, only to be readmitted with similar symptomatology 24 hours later. Subsequently, following repeat discharge she delivered at 34 weeks' gestation, and developed a small bowel obstruction during the immediate postpartum course. With the continued finding of a left lower abdominal mass and computed tomography findings suggestive of perforated sigmoid diverticulitis and resulting small bowel obstruction, laparotomy was performed. Multiple adhesions and phlegmon sequelae of chronic perforation of the sigmoid were confirmed, and a diverting descending colostomy and Hartman's procedure were performed. We present unusual MRI findings of diverticulitis in the third-trimester and review the literature pertaining to this unusual complication of pregnancy.

Physical exercise is probably both beneficial and harmful for the gastrointestinal tract, depending partly on the training intensity. On the one hand, gastrointestinal symptoms such as heartburn, chest pain, nausea, vomiting, abdominal cramps, side ache and diarrhoea are common during heavy exercise. On the other hand, physical activity seems to protect from colon cancer, cholelithiasis and diverticular disease. Constipation has been shown to be related to inactivity. Despite this, no overwhelming evidence exists for a positive effect of physical exercise as a treatment option for chronic constipation. The reasons behind these somewhat discrepant effects are not understood fully. Altered gastrointestinal blood flow, effects on gastrointestinal motor function, neuroendocrine changes and mechanical effects are probably involved. Conflicting results exist regarding the effects of physical activity on gastrointestinal motility. Modern technologies now make motility studies in various parts of the gastrointestinal tract possible. More studies are needed to understand better the effects of physical exercise on the gastrointestinal tract. In particular, the relationship between the training intensity and duration and positive and negative alterations in gastrointestinal physiology needs to be addressed further.

A 77-year-old woman who had been examined 8 months previously because of chronic abdominal pain and an altered pattern of defecation presented to the emergency department with complaints of nausea, vomiting and acute pain in the abdomen. Her appetite was diminished and she had lost 10 kg in the past year. The abdominal X-ray showed a balloon-like, gas-filled intra-abdominal configuration, which proved to be a giant diverticulum of the sigmoid. She was treated by resection of the diverticulum and the sigmoid. A giant diverticulum is a rare complication of diverticulosis, a frequently occurring condition that is encountered most often in the sigmoid; the complication can easily be missed. The presenting symptoms can vary from an acute abdomen to chronic non-specific abdominal complaints. The most important complications of a giant diverticulum are perforation, obstruction or a volvulus. In view of the severity of these complications, resection of that part of the intestine in which the giant diverticulum arises is the treatment of choice.

We aimed to improve symptoms by means of mesalazine in symptomatic colonic diverticular disease patients. One hundred seventy outpatients (98 M, 72 F; age, 67.1 years; range, 39-84 years) were assigned to four different schedules: rifaximin, 200 mg bid (Group R1: 39 pts), rifaximin, 400 mg bid (Group R2: 43 pts), mesalazine, 400 mg bid (Group M1: 40 pts), and mesalazine, 800 mg bid (Group M2: 48 pts), for 10 days per month. At baseline and after 3 months we recorded 11 clinical variables (upper/lower abdominal pain/discomfort, bloating, tenesmus, diarrhea, abdominal tenderness, fever, general illness, nausea, emesis, dysuria), scored from 0 = no symptoms to 3 = severe. The global symptomatic score was the sum of all symptom scores. After 3 months in all schedules but Group R1, 3 of the 11 symptoms improved (P < 0.03); the global score decreased in all groups but Group R1 (P < 0.0001). Mesalazine-treated patients had the lowest global score at 3 months (P < 0.001). Mesalazine is as effective as rifaximin (higher dosage schedule) for diminishing some symptoms, but it appears to be better than rifaximin for improving the global score in those patients.

Bevacizumab is the first U.S. Food and Drug Association-approved vascular endothelial growth factor-targeted agent that greatly increases progression-free and overall survival in combination with standard chemotherapy regimens in patients with metastatic colorectal cancer. Although bevacizumab is generally well tolerated, some serious adverse events have occurred in some patients in clinical trials, including arterial thromboembolism and gastrointestinal (GI) perforation. GI perforation was first observed in the pivotal phase 3 trial, in which six events occurred in bevacizumab group (1.5%), compared with no events in the control group. Since then, similar rates of GI perforation have been observed in other large trials. Typical presentation was abdominal pain associated with constipation and vomiting. Such events occurred throughout treatment and were not correlated with duration of exposure. No difference in rate of GI perforations was found in patients who did and did not have a baseline history of peptic ulcer disease, diverticulosis, and history of chronic use of nonsteroidal anti-inflammatory drugs. However, the incidence of GI perforation seemed to be higher in patients with primary tumor intact, recent history of sigmoidoscopy or colonoscopy, or previous adjuvant radiotherapy, but it is necessary to confirm these preliminary findings by multivariate analyses. The mechanism responsible for causing GI perforation is not known and may be multifactorial. Bevacizumab should be permanently discontinued in patients who develop GI perforation. This article reviews the incidence, presentation, pathogenesis, risk factors, and management of GI perforation in patients with colorectal cancer who are treated with bevacizumab.

In uncomplicated diverticular disease, treatment is aimed at relieving symptoms. The aim of the present study was to evaluate the efficacy of mesalazine for symptomatic relief of uncomplicated diverticular disease of the colon. Two hundred sixty-eight consecutive eligible outpatients (122 male, 146 female; age, 66.1 years; range, 31-81 years) were enrolled in four treatment schedules in a randomized fashion: Group R1 (66 patients), rifaximin, 200 mg bid; Group R2 (69 patients), rifaximin, 400 mg bid; Group M1 (67 patients), mesalazine, 400 mg bid; and Group M2 (66 patients), mesalazine, 800 mg bid. Treatments were administered for 10 days every month for 12 months. Clinical evaluations were performed at admission and at 3-month intervals for 12 months considering 12 clinical variables (upper and lower abdominal pain/discomfort, tenesmus, diarrhea, abdominal tenderness, fever, bloating, general illness, nausea, emesis, dysuria, bleeding) graded as 0 = no symptoms, 1 = mild, 2 = moderate, and 3 = severe. The Global Symptomatic Score (GSS) was calculated using the sum of each symptom score. Two hundred forty-four patients completed the 12- month study; 24 were discontinued (14 treated with rifaximin and 10 treated with mesalazine) either as voluntary dropouts or because they developed side effects and/or complications. Group M2 demonstrated a lower frequency of many symptoms after 6 and 12 months of treatment; the mean GSS was significantly lower in Group M2 after 6 and 12 months of therapy by both intention-to-treat and per-protocol analyses. Patients treated with mesalazine (Groups M1+M2) had a lower GSS than subjects treated with rifaximin (Groups R1+R2) during the 12-month follow-up period. We conclude that cyclic administration of mesalazine is effective for symptomatic relief of uncomplicated diverticular disease of the colon. Some symptoms showed greater improvement with mesalazine, 800 mg bid, than with the other treatment schedules.

Gallstone ileus is a rare complication of gallstone disease, accounting for 1-4% of all bowel obstructions. The phisiopathology is related to the presence of a bilio-enteric fistula. Cholecistoenteric fistulae occur in fewer than 1% of patients with gallstone. We present the case of an 83-years-old woman, complaining of acute abdominal pain, vomiting and mechanical obstruction at admission. She reported a past history of hypertension, recent miocardial ischaemia, diverticular disease and cholelithiasis. A CT scan revealed aerobilia, gastric and duodenal dilatation and a gallstone impacted just beyond the duodeno-jejunal junction. An exploratory supraumbilical laparotomy was performed: revealing a 4-cm gallstone impacted just caudal to the Treitz ligament. We then performed an enterolithotomy. According to the literature, enterolithotomy is the most commonly used surgical technique, whereas enterolithotomy combined with cholecistectomy and fistulectomy is indicated only in selected cases. The clinical presentation depends on impaction site and generally includes abdominal pain, nausea and vomiting. Some cases may present haematemesis due to mucosal erosion. The gold-standard investigation technique is CT scan.

Multiple diverticulosis of jejunum represents an uncommon pathology of the small bowel. The disease is usually asymptomatic and must be taken into consideration in cases of unexplained malabsorption, anemia, chronic abdominal pain or discomfort. Related complications such as diverticulitis, perforation, bleeding or intestinal obstruction appear in 10-30% of the patients increasing morbidity and mortality rates. We herein report a case of a 55 year-old man presented at the emergency department with acute abdominal pain, vomiting and fever. Preoperative radiological examination followed by laparotomy revealed multiple giant jejunal diverticula causing intestinal obstruction. We also review the literature for this uncommon disease.
