Laparostomy for severe intra-abdominal infection complicating colorectal disease

PURPOSE: The aim of this study was to evaluate the use of laparostomy in the management of patients with severe intra-abdominal infection resulting from colorectal disease. METHODS: Seven patients, four with inflammatory bowel disease, two with colorectal carcinoma, and one with diverticular perforation, underwent laparostomy during a six-year period for postoperative, severe, intra-abdominal infection. RESULTS: The median age was 42 years, the mean Acute Physiology and Chronic Health Evaluation II score was 22.7, and the observed mortality was 28.6 percent (2/7 patients). In one patient the laparostomy was closed at 11 days; in all the others the wound was left to heal by granulation and contraction, and two of these later required reconstructive surgery. The median follow-up was three years and seven months. CONCLUSION: Laparostomy is an effective and practical method of managing patients with severe intra-abdominal infection as a result of colorectal disease.Presented at the European Council of Coloproctology Biennial Meeting, Edinburgh, United Kingdom, June 17 to 19, 1997.     

Management of enteroatmospheric fistula with negative pressure wound therapy in open abdomen treatment: a multicentre observational study

The management of enteroatmospheric fistula (EAF) in open abdomen (OA) therapy is challenging and associated with a high mortality rate. The introduction of negative pressure wound therapy (NPWT) in open abdomen management significantly improved the healing process and increased spontaneous fistula closure. Retrospectively, we analysed 16 patients with a total of 31 enteroatmospheric fistulas in open abdomen management who were treated using NPWT in four referral centres between 2004 and 2014. EAFs were diagnosed based on clinical examination and confirmed with imaging studies and classified into low (<200 ml/day), moderate (200–500 ml/day) and high (>500 ml/day) output fistulas. The study group consisted of five women and 11 men with the mean age of 52·6 years [standard deviation (SD) 11·9]. Since open abdomen management was implemented, the mean number of re‐surgeries was 3·7 (SD 2·2). There were 24 EAFs located in the small bowel, while four were located in the colon. In three patients, EAF occurred at the anastomotic site. Thirteen fistulas were classified as low output (41·9%), two as moderate (6·5%) and 16 as high output fistulas (51·6%). The overall closure rate was 61·3%, with a mean time of 46·7 days (SD 43·4). In the remaining patients in whom fistula closure was not achieved (n = 12), a protruding mucosa was present. Analysing the cycle of negative pressure therapy, we surprisingly found that the spontaneous closure rate was 70% (7 of 10 EAFs) using intermittent setting of negative pressure, whereas in the group of patients treated with continuous pressure, 57% of EAFs closed spontaneously (12 of 21 EAFs). The mean number of NPWT dressing was 9 (SD 3·3; range 4–16). In two patients, we observed new fistulas that appeared during NPWT. Three patients died during therapy as a result of multi‐organ failure. NPWT is a safe and efficient method characterised by a high spontaneous closure rate. However, in patients with mucosal protrusion of the EAFs, spontaneous closure appears to be impossible to achieve.     

Initial Experience of Laparostomy with Immediate Vacuum Therapy in Patients with Severe Peritonitis

INTRODUCTION

To report our initial experience of laparostomy and immediate intra-abdominal vacuum therapy in patients with severe peritonitis due to intra-abdominal catastrophes.

PATIENTS AND METHODS

Twenty-seven patients underwent emergency laparotomy and laparostomy formation with the application of immediate intra-abdominal TRAC–VAC® therapy (male:female ratio, 1:1.2; median age, 73 years; range, 34–84 years). Predicted mortality was assessed using the P-POSSUM score and compared with clinically observed outcomes.

RESULTS

Ten patients (37%) with a mean predicted P-POSSUM mortality of 72%, died of sepsis and multi-organ failure. Seventeen patients (mean P-POSSUM 48% expected mortality) survived to discharge. One patient with pancreatitis died from small bowel obstruction 1-year post discharge, two patients developed a small bowel fistula. One patient had an allergic reaction to the VAC dressing. Our patients, treated with laparostomy and TRAC VAC therapy, had a significantly improved observed survival when compared to P-POSSUM expected survival (P = 0.004).

CONCLUSIONS

Laparostomy with immediate intraperitoneal VAC therapy is a robust and effective system to manage patients with intra-abdominal catastrophes. There were significantly improved outcomes compared to the mortality predicted by P-POSSUM scores. Damage control surgery with laparostomy formation and intra-abdominal VAC therapy should be considered in patients with severe peritonitis.
