A National Study of Clinical Results After Emergency Operation for Perforated Diverticulitis

A National, Registry Based Study of Clinical Results After Emergency Operation for Perforated Diverticulitis to Compare Laparoscopic Lavage and Resection Surgery in Routine Use.

The aim of this study is to evaluate clinical results and effect on health and well-being in patients operated for perforated diverticulitis with purulent peritonitis by laparoscopic lavage in Sweden when used outside of prospective studies/trials and in comparison with the traditional treatment, i.e. colon resection with or without stoma formation.

A secondary aim is to evaluate the outcome after fecal peritonitis.

The hypothesis is that laparoscopic lavage as treatment for perforated diverticulitis with purulent peritonitis is safe, efficient and cost saving, when used in routine health care.

Inclusion Criteria:

• All patients registered in the Patient registry with ICD 10 codes K57 classified as emergency admissions and with the Nordic Medico-Statistical Committee (NOMESCO) code JAH01(diagnostic laparoscopy), JFB46 (resection of sigmoid colon), JFB60 (resection of sigmoid colon, sigmoidostomy and closure of the distal stump), JFB61 (laparoscopic resection of sigmoid colon, sigmoidostomy and closure of the distal stump), JFB63 (other colon resection, colostomy and closure of the distal stump), JAK04 (laparoscopy and peritoneal lavage), JAW97 (other laparoscopic operation involving abdominal wall, mesentery, peritoneum or the omentum)

Exclusion Criteria:

• Patients where hospital records reveal that the index admission was misclassified (not perforated diverticulitis) will be excluded.
• Patients classified as Hinchey 1-2.
• No informed consent received or withdrawal of consent (questionnaire)
