Treatment of small-bowel fistulae in the open abdomen with topical negative-pressure therapy.

BACKGROUND An open abdomen (OA) can result from surgical management of trauma, severe peritonitis, abdominal compartment syndrome, and other abdominal emergencies. Enteroatmospheric fistulae (EAF) occur in 25% of patients with an OA and are associated with high mortality. METHODS We report our experience with topical negative pressure (TNP) therapy in the management of EAF in an OA using the VAC (vacuum asisted closure) device (KCI Medical, San Antonio, TX). Nine patients with 17 EAF in an OA were treated with topical TNP therapy from January 2006 to January 2009. Surgery with enterectomy and abdominal closure was planned 6 to 10 weeks later. RESULTS Three EAF closed spontaneously. The median time from the onset of fistulization to elective surgical management was 51 days. No additional fistulae occurred during VAC therapy. One patient with a short bowel died as a result of persistent leakage after surgery. CONCLUSIONS Although previously considered a contraindication to TNP therapy, EAF can be managed successfully with TNP therapy. Surgical closure of EAFs is possible after several weeks.

Small Bowel Obstruction After Antecolic Antegastric Laparoscopic Roux-en-Y Gastric Bypass Without Division of Small Bowel Mesentery: A Single-Centre, 7-Year Review

Reported incidence of small bowel obstruction (SBO) after laparoscopic Roux-en-Y gastric bypass varies between 1.5% and 3.5%. It has been suggested that the antecolic antegastric laparoscopic Roux-en-Y gastric bypass (AA-LRYGB) is associated with a low incidence of internal herniation (IH). Therefore we routinely did not close mesenteric defects. The records of 652 consecutive patients undergoing primary AA-LRYGB from January 2003 to December 2009 in a single institution were retrospectively reviewed to determine the incidence, etiology, clinical symptoms, radiologic diagnostic accuracy and operative outcomes of SBO. Of the 652 patients, 63 (9.6%) developed SBO. The majority (6.9%, 45 patients) had a SBO due to IH. In 41 (91%) cases, the IH was at the jejunojejunostomy (JJ), four cases had an IH at Petersen’s space. Adhesions and ventral hernia were found in 14 (2.1%) and four (0.6%) cases, respectively. Twenty-nine out of 63 cases had negative computed tomography (CT) findings and IH was diagnosed on CT in only 33% (14/45) of patients with IH. All patients underwent diagnostic laparoscopy. No bowel resections had to be performed. In contrast to previous reports, a high incidence of SBO with a high rate of IH at the JJ site was found in our series. Accuracy of CT is low and diagnostic laparoscopy is mandatory when SBO is suspected. Since 2010 we have started closing the JJ site, and data on SBO are collected prospectively. We believe that closing of the mesenteric defects is a mandatory step, even in an AA-LRYGB.

Gastrogastric Fistula after Gastric Bypass – Is Surgery Always Needed?

Because of regain of weight to BMI 37.1 kg/m2 6 years after a VBG, a 41-year-old female now underwent revision to divided Roux-en-Y gastric bypass, performed laparoscopically. 12 days postoperatively, she started bleeding from the main stomach, and CT scan revealed that the bypassed stomach was distended with clot. She was treated conservatively and stopped bleeding. Upper GI series 2 weeks postoperatively revealed a large gastrogastric fistula between the tiny pouch and the bypassed stomach. We initially planned to close the fistula. However, upper GI series 2 months and 4 months postoperatively showed no sign of gastrogastric fistula, and proton pump inhibitors were stopped. At 1 year after gastric bypass, our patient has had good weight loss.

Postsurgery Activation of Dormant Liver Micrometastasis: a Case Report and Review of Literature

BackgroundWe present the case of a 55-year-old woman who underwent a Whipple procedure for pancreatic adenocarcinoma. The preoperative work-up showed no signs of liver metastasis and confirmed the patient’s operability, but at less than 40 days postoperatively there were diffuse liver metastasis present on CT. This rapid evolution raises the question whether current staging systems are adequate in determining a patient’s operability. It also suggests an interaction between the primary tumor and the host and the existence of disseminated tumor cells.DiscussionIn this article, we give an explanation for the clinical evolution presented in our case using the “integrated organ” and the “concomitant resistance” hypotheses. We believe that, if these theories continue to prove their viability, the search for disseminated tumor cells will be essential for good clinical practice in this type of pathology.

SILS Sigmoidectomy Versus Multiport Laparoscopic Sigmoidectomy for Diverticulitis

Background and Objectives: In this single-institution study, we aimed to compare the safety, feasibility, and outcomes of single-incision laparoscopic sigmoidectomy (SILSS) with multiport laparoscopic sigmoidectomy (MLS) for recurrent diverticulitis. Methods: Between October 2011 and February 2013, 60 sigmoidectomies were performed by the same surgeon. Forty patients had a MLS and 20 patients had a SILSS. Outcomes were compared. Results: Patient characteristics were similar. There was no difference in morbidity, mortality or readmission rates. The mean operative time was longer in the SILSS group (P = .0012). In a larger proportion of patients from the SILSS group, 2 linear staplers were needed for transection at the rectum (P = .006). The total cost of disposable items was higher in the SILSS group (P < .0001). No additional ports were placed in the SILSS group. Return to bowel function or return to oral intake was faster in the SILSS group (P = .0446 and P = .0137, respectively). Maximum pain scores on postoperative days 1 and 2 were significantly less for the SILSS group (P = .0014 and P = .047, respectively). Hospital stay was borderline statistically shorter in the SILSS group (P = .0053). SILSS was also associated with better cosmesis (P < .0011). Conclusion: SILSS is feasible and safe and is associated with earlier recovery of bowel function, a significant reduction in postoperative pain, and better cosmesis.
