Pneumatosis cystoides intestinalis induced by the alpha-glucosidase inhibitor complicated from sigmoid volvulus in a diabetic patient.

INTRODUCTION: We present the case of a diabetic patient on treatment with acarbose who had presented a sigmoid volvulus with localized cystic pneumatosis of the sigmoid colon. CASE REPORT: A 72-year-old patient with a medical history of atrial fibrillation, DNID in treatment since 10 years by acarbose. The patient was admitted to the emergency for abdominal pain and occlusive syndrome since 48 h without fever or nausea or vomiting. A CT scan was performed that showed a dolichocolon with a sigmoid volvulus. The colonic wall was thickening as well as submucosal and subserosal gas, without extra digestive air or collections. A rectosigmoidoscopy was achieving that showed a sigmoid volvulus with multiple small projections like a submucosa gas bubbles. A laparoscopic non-oncologic sigmoidectomy with primary termino terminal colorectal anastomosis was performed. During the surgical procedure, an aspect of PCI of the sigmoid colon was found. The sigmoid colon was long like a dolichocolon, dilated, and partially twisted. DISCUSSION: PCI is a rare condition characterized by the presence of multiple pneumokystes at different layers of the colonic wall. In emergency setting, the presence of colonic pneumatosis precludes the differential diagnosis between the PCI and mesenteric ischemia or ischemic colitis. It can be the cause of unnecessary explorative laparotomy. CONCLUSION: PCI is rare disease, in emergency setting, we had to consider in differential diagnosis with colonic vascular disorders.

Multicenter phase III randomized trial comparing laparoscopy and laparotomy for colon cancer surgery in patients older than 75 years: the CELL study, a Fédération de Recherche en Chirurgie (FRENCH) trial.

BACKGROUND: Several multicenter randomized controlled trials comparing laparoscopy and conventional open surgery for colon cancer have demonstrated that laparoscopic approach achieved the same oncological results while improving significantly early postoperative outcomes. These trials included few elderly patients, with a median age not exceeding 71 years. However, colon cancer is a disease of the elderly. More than 65% of patients operated on for colon cancer belong to this age group, and this proportion may become more pronounced in the coming years. In current practice, laparoscopy is underused in this population. METHODS: The CELL (Colectomy for cancer in the Elderly by Laparoscopy or Laparotomy) trial is a multicenter, open-label randomized, 2-arm phase III superiority trial. Patients aged 75 years or older with uncomplicated colonic adenocarcinoma or endoscopically unresectable colonic polyp will be randomized to either colectomy by laparoscopy or laparotomy. The primary endpoint of the study is overall postoperative morbidity, defined as any complication classification occurring up to 30 days after surgery. The secondary endpoints are: 30-day and 90-day postoperative mortality, 30-day readmission rate, quality of surgical resection, health-related quality of life and evolution of geriatric assessment. A 35 to 20% overall postoperative morbidity rate reduction is expected for patients operated on by laparoscopy compared with those who underwent surgery by laparotomy. With a two-sided α risk of 5% and a power of 80% (ß = 0.20), 276 patients will be required in total. DISCUSSION: To date, no dedicated randomized controlled trial has been conducted to evaluate morbidity after colon cancer surgery by laparoscopy or laparotomy in the elderly and the benefits of laparoscopy is still debated in this context. Thus, a prospective multicenter randomized trial evaluating postoperative outcomes specifically in elderly patients operated on for colon cancer by laparoscopy or laparotomy with curative intent is warranted. If significant, such a study might change the current surgical practices and allow a significant improvement in the surgical management of this population, which will be the vast majority of patients treated for colon cancer in the coming years.

Preservation of the arterial vascularisation after hepatic artery pseudoaneurysm following orthotopic liver transplantation: long-term results.

BACKGROUND: Hepatic artery pseudoaneurysm (HAP) is a serious complication of orthotopic liver transplantation (OLT). The aim of this study was to determine risk factors for HAP and the best management of this complication. MATERIAL AND METHODS: Between 1990 and 2005, 787 OLT were performed at our center. Patients who developed HAP were identified from our prospective database and risk factors of HAP were identified. Management of HAP was analyzed retrospectively. RESULTS: There were 16 OLT (2.5%) complicated by HAP [median delay =13 days; range: 4-100 days]. Presentation was massive bleeding with shock (n=13), pain (n=2), or transient gastrointestinal bleeding (n=1). Bacteriological culture of HAP wall or ascites fluid was positive in 13 (81%) patients. Bilio-enteric anastomosis and biliary leak were identified as risk factors for HAP (p=0.011 and 0.002, respectively), whereas indication for OLT, surgical technique (full-graft OLT versus other techniques), and re-LT were not. Mortality rate after HAP rupture was 53% (7/13), but no deaths occurred in the 3 patients treated before rupture. Treatment included: excision and immediate revascularization [n=7; early mortality =2 (28%), long-term graft survival =4 (57%)], hepatic artery ligation [n=5; early mortality =3 (80%);, long-term graft survival with good liver function =0], and endovascular treatment [n=2; early mortality =0, long-term survival with good liver function =2]. CONCLUSIONS: HAP post-OLT carries a high mortality rate when detected after rupture, but recognition before rupture usually allows a successful outcome. Reconstruction with bilio-enteric anastomosis and postoperative biliary leak increase the risk for HAP. In these settings, CT with contrast injection should be performed to screen for HAP when there is any suspicion. Graft revascularization should be attempted whenever possible.
