Rectosigmoid resection during Visceral-Peritoneal Debulking (VPD) in patients with stage IIIC-IV ovarian cancer: morbidity of gynecologic oncology vs. colorectal team.

OBJECTIVE: This study investigates the specific morbidity of rectosigmoid resection (RSR) during Visceral-Peritoneal Debulking (VPD) in a consecutive series of patients with stage IIIC-IV ovarian cancer and compares the results of the colo-rectal vs. the gynaecologic oncology team. METHODS: All patients with the International Federation of Gynecology and Obstetrics (FIGO) stage IIIC-IV ovarian cancer who had VPD and RSR were included in the study. Between 2009 and 2013 all operations were performed by the gynecologic oncology team alone (group 1). Since 2013 the RSR was performed by the colorectal team together with the gynecologic oncologist (group 2). All pre-operative information and surgical details were compared to exclude significant bias. Intra- and post-operative morbidity events were recorded and compared between groups. RESULTS: One hundred and sixty-two patients had a RSR during VPD, 93 in group 1 and 69 in group 2. Groups were comparable for all pre-operative features other than: albumin (1<2) hemoglobin (2<1) and up-front surgery (1>2). Overall morbidity was 33% vs. 40% (p=0.53), bowel specific morbidity 11.8% vs. 11.5% (p=0.81), anastomotic leak 4.1% vs. 6.1% (p=0.43) and re-operation rate 9.6% vs. 6.1% (p=0.71) in groups 1 and 2, respectively. None of them were significantly different. The rate of bowel diversion was 36.5% in group 1 vs. 46.3% in group 2 (p=0.26). CONCLUSIONS: Our study failed to demonstrate any significant difference in the morbidity rate of RSR based on the team performing the surgery. These data warrant further investigation as they are interesting with regards to education, finance, and medico-legal aspects.

Ischemic gall bladder perforation: a complication of type A aortic dissection.

Malperfusion of end organs occurs in 20% to 40% patients with acute type A aortic dissection. Because irreversible ischemia is a time-dependent event, expedient diagnosis and treatment are necessary. We herein report successful surgical management of a patient with acute type A aortic dissection causing transient gut ischemia and a rare gall bladder perforation. We implemented one-stage surgical and laparoscopic management approach for the diagnosis and treatment. Increased awareness of this complication and appropriate use of available diagnostic tools may improve the outcome in similar patients. Patients with aortic dissection complicated by visceral ischemia require a prompt sequential and rational multidisciplinary approach for successful management.

Laparoscopic-assisted endoscopic sigmoidopexy: a new surgical option for sigmoid volvulus.

OBJECTIVES: Sigmoid volvulus accounts for 5% of cases of large-bowel obstruction. Here, we present the development of a new minimally invasive treatment method that aims to reduce the complication rate of standard percutaneous endoscopic colostomy tube insertion and negate the need for prolonged anesthesia or colectomy. METHODS: Six patients underwent laparoscopic-assisted endoscopic sigmoidopexy for recurrent sigmoid volvulus at a mean age of 80.5 years (range, 76-83). The volvulus was decompressed endoscopically before laparoscopic adhesiolysis and detorsion of the sigmoid. Finally, the sigmoid was approximated with the anterior abdominal wall, and 2 endoscopically placed percutaneous endoscopic colostomy tubes were inserted. Later, the external component of the percutaneous endoscopic colostomy tubes was removed, and the internal parts were passed by way of the rectum. RESULTS: Each operation was completed successfully in a mean time of 69 minutes and with no intraoperative complication. The mean postoperative stay was 20 days (range, 4-54). At median follow-up of 10.8 months, all patients were tube free with no incidence of recurrent volvulus, inadvertent tube traction, or leak. CONCLUSIONS: This preliminary report shows laparoscopic-assisted endoscopic sigmoidopexy to be a safe treatment modality for recurrent sigmoid volvulus. As such, it is particularly useful for elderly patients, for whom colectomy is a high-risk procedure.

A prospective, longitudinal study of nonconventional strictureplasty in Crohn's disease.

BACKGROUND: Bowel-sparing techniques have been proposed to avoid extended or repeated resections in patients with Crohn'rsquo;s disease (CD), but without precise indications, prospective evaluation, and with a technically limited repertoire. STUDY DESIGN: A prospective longitudinal study of new nonconventional strictureplasties (NCSP) in order to evaluate the safety, type and site of recurrence, and longterm clinical and surgical efficacy. RESULTS: Between January 1993 and December 2002, 102 among 305 consecutive patients underwent at least one NCSP for complicated CD. Patients were treated following precise indications and then included in a prospective database with scheduled followup. Factors claimed to influence postoperative and longterm outcomes and type and site of recurrence were analyzed. We performed 48 ileoileal side-to-side isoperistaltic strictureplasty (SP), 41 widening ileocolic SP, 32 ileocolic side-to-side isoperistaltic SP, associated with Heineke-Mikulicz SP (in 80 procedures) or with minimal bowel resections or both (in 47 procedures). Postoperative mortality was nil; complication rate was 5.7%. Ten years clinical and surgical recurrence rates were 43% and 27%, respectively. Recurrence rate on an NCSP site was 0.8%. No specific factor was identified as related to postoperative or longterm outcomes. CONCLUSIONS: Perioperative and longterm results of NCSP are comparable to or even better than both conservative and resective surgery as reported in the literature, with a low recurrence rate on the NCSP site. Considering the unpredictability of the clinical course of CD and the lifetime need for surgical procedures, NCSP, together with minimal resection and classic SP repertoire, should be considered first-line treatment in complicated CD.

Contrast radiology, computed tomography and ultrasonography in detecting internal fistulas and intra-abdominal abscesses in Crohn's disease: a prospective comparative study.

OBJECTIVE: Accurate assessment of intestinal complications of Crohn's disease (CD) is extremely important, both in clinical practice and in trials. The accuracy of radiographic and ultrasonographic diagnosis of internal fistulae and abscesses complicating CD is still debated and requires further investigation. We compared ultrasonography (US) and contrast radiography in detecting intestinal fistulae and abscesses complicating CD. METHODS: A prospective study was carried out on 625 consecutive CD patients who underwent complete evaluation of the intestinal tract by means of colonoscopy and double contrast barium enema, small bowel enteroclysis, and abdominal ultrasound (US). Computed tomography (CT) was also carried out in cases of severe CD with clinical suspicion of septic complications. The accuracy of US, barium radiology, and CT in detecting internal fistulae and abscesses was assessed by comparing results with intraoperative findings in 128 consecutive patients who underwent operation immediately after diagnostic workup. RESULTS: Internal fistulae and intra-abdominal abscesses were identified intraoperatively in 56 (43.7%) and 26 (20.3%) patients, respectively. Diagnostic accuracy of US and x-ray studies in detecting internal fistulae was comparable (85.2% vs 84.8%), with sensitivity of 71.4% for US and 69.6% for x-ray studies, and specificity of 95.8% for both. Combination of radiographic techniques and US significantly improved diagnostic accuracy in detection of internal fistulae. In severe cases of CD with clinical suspicion of septic complications such as abdominal mass or fever, the accuracy of US, barium studies, and CT was 88.5%, 80.3%, and 77%, respectively (p = ns). The presence of abscesses was correctly detected in 90.9% of cases by means of US and in 86.4% by CT (p = ns), although accuracy was higher for CT (91.8%) than for US (86.9%) because of false positive results in US studies. CONCLUSIONS: Despite the fact that barium radiology is widely considered the method of choice in detection of internal fistulae, accuracy is not entirely satisfactory. Comparable accuracy was found for US and CT. The combination of barium and US studies, or the sole use of US in more CD patients with more severe disease, can reliably detect most internal fistulae and abscesses.
