A rare case of pneumatosis cystoides intestinalis with bowel perforation and secondary sepsis.

MATERIALS AND METHODS: We present here the case of an 83 y.o. male with intestinal perforation from pneumatosis cystoides intestinalis and consequent sepsis. RESULTS: The patient underwent urgency intestinal resection in our institute, with complete restitution ad integrum Discussion: Pneumatosis cystoides intestinalis is a rare affection, which can be categorized as primary (15%) or idiopathic( 85%). The clinical appearance can be very variable from patient to patient, since it can be completely asymptomatic or start with life-threatening clinical presentation of bowel perforation and sepsis. There are various theories about the formation of the gas bubbles trough the intestinal wall. The mechanical theory assumes that the gas, tearing trough the intestinal wall seeps trough it. The bacterial theory assumes that antibiotic treatment, such as with metronidazole, allows the creation of gas by microbiological elements like Clostridium Perfringens or Clostridium Difficile. The pulmonary theory, instead, assumes that air released from ruptured alveoli gets into the mediastinum and retro peritoneum, reaching the intestinal tract. The treatment is conservative most of the times, except for the cases of intestinal perforation and sepsis. CONCLUSIONS: Despite of the long history of the disease, with the first description in 1783, little is known nowadays about PCI, due to the rarity of symptomatic disease. Further studies are needed to better evaluate the aetiology of the condition, and the prognostic criteria, which may be very important for clinical decisions about conservative or surgical treatment.

The "Watch and wait" approach following chemoradiotherapy for rectal cancer: a case series and review of literature.

Neoadjuvant chemoradiotherapy (NCRT) combined with total mesorectal excision (TME) is currently the gold standard for locally advanced low-lying rectal cancer (LACR). Around 20-30% of patients after NCRT can achieve clinical complete response (cCR); 5-44% of the patients who underwent TME achieve pathological complete response (pCR) on postoperative histopathologic studies. In the present study we perform a review of current Literature and retrospectively analyze our personal experience on "watch and wait" approach after cCR. Further studies are needed to establish an internationally accepted definition of clinical complete response, to delineate the real role of MRI in the post-treatment staging and to determine more precise predictors of sustained clinical complete response. The eventual presence of long-term morbidity and adverse effects after chemoradiation needs as well to be better evaluated. Evidence suggests that watch and wait approach is associated with substantially better quality of life and functional outcomes compared with standard surgical resection.

Cholecystogastric fistula. A case report and literature review.

Cholecystogastric fistulas is a rare complication of gallstone. Even if well described in the literature, this condition still poses a debate on diagnosis and surgical treatment. We present a case of a 35 year's old female which unexpectedly presented a cholecystogastric fistula during a laparoscopic cholecystectomy, treated successfully with fistula transection and repair and cholecystectomy through an open access. The open access remains the preferable option in this cases but laparoscopic techniques are being used worldwide with increasing success. The preoperative diagnosis remains difficult for the unspecific symptoms. KEY WORDS: Biliodigestive Fistula, Gallstone Ileus, Gastric Fistula, Biliary Fistula, Cholecystitis.

Complete endoscopic closure (clipping) of a large esophageal perforation after pneumatic dilation in a patient with achalasia.

The risk of esophageal perforation following endoscopic balloon dilation for achalasia is in the range of 1%-5%, with a mortality rate of 1%-20%. Perforations need to be recognized early, and, if reasonable, an immediate endoscopic repair should be pursued quickly. Herein, we report a case of successful endoscopic closure by clipping of a large iatrogenic perforation in a patient with achalasia. An 80-year-old woman with achalasia was admitted to our institution to undergo pneumatic dilation. A 40-mm balloon dilator with inflation pressure of 20 psi was used for 2 minutes as usual. During the procedure, the patient had a transient bradycardia. Endoscopic control showed a 2-cm rupture of the distal esophagus. Prompt endoscopic repair of the perforation by endoclips (n=6) was then attempted, followed by conservative management by total parenteral nutrition and intravenous antibiotics. Endoscopic clipping completely closed the esophageal perforation. The patient was given oral nutrition 10 days later without any complications. Six months after discharge from the hospital, the patient was healthy and free of dysphagia. Endoscopy showed complete healing of the esophageal mucosa without luminal stenosis. This report highlights that prompt endoscopic clipping is a useful means to close a large esophageal perforation caused by pneumatic dilation.

A Western single-center experience with endoscopic submucosal dissection for early gastrointestinal cancers.

Endoscopic submucosal dissection (ESD) has gained worldwide acceptance as a treatment for early gastrointestinal cancers (EGICs). However, the management of these tumors in the Western world is still mainly surgical. Our aim was to evaluate the safety and feasibility of ESD at a European center. Based on the knowledge transferred by one of the most experienced Japanese institutions, we conducted a pilot study on 25 consecutive patients with EGICs located in the esophagus (n = 3), stomach (n = 7), duodenum (n = 1), and colon (n = 14) at our tertiary center over a 2-year-period. The main outcome measurements were complete (R0) resection, as well as en-bloc resection and the management of complications. The R0 and en-bloc resection rates were 100% and 84%, respectively. There were three cases of bleeding and five cases of perforation. With a median follow up of 18 months, two recurrences were observed. We conclude that ESD for early esophageal and gastric cancers is feasible and effective, while colonic ESD requires more expertise.

[Conventional colonoscopy versus chromoendoscopy and magnifying endoscopy for the diagnosis of colorectal lesions: a comparative prospective study in 995 patients]. / Colonscopia convenzionale versus cromoendoscopia e magnificazione endoscopica per la diagnosi delle lesioni colorettali: studio prospettico comparativo su 995 pazienti.

Early endoscopic diagnosis of colorectal cancers is the best tool for the reduction of colorectal cancer mortality, but conventional colonoscopy seems unable to detect minor changes in the colorectal mucosa. The authors compare the results of conventional colonoscopy and chromoendoscopy plus magnifying endoscopy for the detection of colorectal lesions. This prospective study evaluated 995 consecutive selected patients. All patients with a previous diagnosis of colorectal polyps, inflammatory bowel disease, history of colorectal surgery, high coagulative risk or poor bowel preparation were excluded from the study. All examinations were performed by a single endoscopist. The authors compared the results of conventional endoscopy and chromoendoscopy with a 0.4% indigo carmine solution and magnifying endoscopy. At the end of each examination, data from ordinary and dye-spraying views were carefully recorded. A total of 202 protruding, 99 flat and 5 depressed lesions were detected. The incidence of high-grade dysplasia and early carcinoma was 9.9% for protruding lesions, 13.1% for flat lesions and 60% for depressed lesions. Chromoendoscopy revealed new neoplastic patterns not detectable at conventional endoscopy in 127 patients. This prospective study shows the high accuracy rate of chromoendoscopy for the detection of non-polypoid lesions. Chromoendoscopy could be used as a routine procedure in order to enhance the early diagnosis of colorectal cancers.

[Extrauterine endometriosis: what interest for the general surgeon? Presentation of 3 clinical cases and review of the literature]. / Endometriosi extrauterina: quale interesse per il chirurgo generale? Presentazione di 3 casi clinici e revisione della letteratura.

Extragonadal endometriosis is rarely diagnosed preoperatively for the variety of its localizations. Presentations to general surgeons may be atypical and pose diagnostic difficulty, mimicking other acute diseases. We report three cases treated with surgical operation. Case 1: a 28-year-old woman admitted for bowel obstruction due to coecal endometriosis, with appendix mucocele, peritoneal pseudomyxoma and ovarian endometrioma. The patient underwent right colectomy and right adnexectomy in the emergency setting. Case 2: a 31-year-old woman with endometriosis of the distal extraperitoneal portion of the round ligament presenting as an irreducible inguinal hernia. An operation was performed: the round ligament and a polycystic structure encompassing it were completely excised. Case 3: a 41-year-old woman, with umbilical endometriosis diagnosed by her gynaecologist, was admitted to our department for excision. Surgical treatment of extragonadal endometriosis is adequate. However, postoperative follow-up is mandatory and hormonal suppressive therapy may be indicated by the gynaecologist.
