Cytomegalovirus infection as a rare cause of colitis.

A 62 year-old-man with low anterior rectal resection and protective ileostomy, for low rectal neo and neoadjuvant QT +RT. Then ileostomy closure without incidences. On the 3rd postoperative day, he started with fever peaks and diarrhea. An abdominal CT scan showed diffuse thickening of the wall of the descending colon compatible with colitis and colonoscopy showed deep rectal ulcers with punch-like morphology with hyperemic mucosa with erythematous stippling of erosive appearance, showing this ulcerative pattern with numerous lesions and intensely edematous and congestive mucosa covered with abundant fibrinopurulent exudate in the descending colon. Biopsies and stool cultures were negative, but serologies were positive for CMV. Suspected CMV infection in a immunosuppressed by chemotherapy patient, he was treated with ganciclovir. The patient presented clinical improvement, without fever or diarrhea and improvement of the punch ulcers in the endoscopic controls, so he could be discharged from the hospital with follow-up in the outpatient consulting offices.

Surgical acute abdomen and COVID-19 vaccination.

In response to the publication "Acute appendicitis, foreign bodies and COVID-19 vaccination: correspondence", we reviewed the association between acute surgical abdomen and COVID-19 vaccination.

Idiopathic myointimal hyperplasia of the mesenteric veins, an uncommon cause of intestinal ischemia.

Idiopathic myointimal hyperplasia of the mesenteric veins (IMHMV) is an uncommon cause of intestinal ischemia. It was firstly described by Genta and Haggit in 1991. Only a few cases have been reported and it is difficult to know the true incidence.

Uncommon causes of acute appendicitis: foreign bodies in the cecal appendix.

A 50-year-old woman with a history of hysterectomy for endometrial cancer in 2015 visited because of abdominal pain for 1 week and fever simultaneous with her third dose of the COVID-19 vaccine. Physical examination revealed a mobile mass in the right iliac fossa, and laboratory testing showed C-reactive protein at 3 mg/dL, with no further changes. Ultrasound results were consistent with an appendiceal inflammatory mass, and a CT scan revealed an appendicolith as likely cause. The patient was subjected to laparoscopy, which found inside the mass a metallic piece (dental prosthesis) that perforated the appendiceal lumen at the mid portion of the appendix. Appendectomy was completed and the patient was discharged on the third day post-procedure.

Safety of propofol sedation administered by an endoscopy team for outpatient colonoscopy.

Sedation during colonoscopy increases comfort and reduces unexpected patient movement. Colorectal cancer (CRC) screening colonoscopies performed under propofol sedation controlled by our endoscopy team (ET) were retrospectively studied for eight months.

Twisting of sleeve gastrectomy: two ways of clinic presentation.

Laparoscopic sleeve gastrectomy is an increasingly widespread bariatric surgical technique thanks to its good outcomes and apparent simplicity. However, complications may arise, including hemorrhage, gastric fistula, and stenosis, which can be either organic or functional. Functional stenosis is caused by gastric tube twisting. We present two cases of patients who underwent laparoscopic sleeve gastrectomy and who were subsequently diagnosed with gastric twisting. Both cases required conversion to laparoscopic gastric bypass. Accompanying symptoms may vary but they commonly include early satiety, epigastric pain associated with food intake, gastroesophageal reflux and early vomiting. Although diagnose is mainly clinical, it requires high suspicion since endoscopy and gastrointestinal studies are not conclusive. The principal therapeutic options are endoscopic dilatations, serotomy and conversion to gastric bypass.
