Peritonitis: laparoscopic approach.

BACKGROUND: Laparoscopy has became as the preferred surgical approach to a number of different diseases because it allows a correct diagnosis and treatment at the same time. In abdominal emergencies, both components of treatment - exploration to identify the causative pathology and performance of an appropriate operation - can often be accomplished via laparoscopy. There is still a debate of peritonitis as a contraindication to this kind of approach. Aim of the present work is to illustrate retrospectively the results of a case-control experience of laparoscopic vs. open surgery for abdominal peritonitis emergencies carried out at our institution. METHODS: From January 1992 and January 2002 a total of 935 patients (mean age 42.3 +/- 17.2 years) underwent emergent and/or urgent surgery. Among them, 602 (64.3%) were operated on laparoscopically (of whom 112 -18.7% - with peritonitis), according to the presence of a surgical team trained in laparoscopy. Patients with a history of malignancy, more than two previous major abdominal surgeries or massive bowel distension were not treated Laparoscopically. Peritonitis was not considered contraindication to Laparoscopy. RESULTS: The conversion rate was 23.2% in patients with peritonitis and was mainly due to the presence of dense intra-abdominal adhesions. Major complications ranged as high as 5.3% with a postoperative mortality of 1.7%. A definitive diagnosis was accomplished in 85.7% (96 pat.) of cases, and 90.6% (87) of these patients were treated successfully by Laparoscopy. CONCLUSION: Even if limited by its retrospective feature, the present experience let us to consider the Laparoscopic approach to abdominal peritonitis emergencies a safe and effective as conventional surgery, with a higher diagnostic yield and allows for lesser trauma and a more rapid postoperative recovery. Such features make Laparoscopy a challenging alternative to open surgery in the management algorithm for abdominal peritonitis emergencies.

The diagnosis of non-palpable lesions in laparoscopic surgery of the colon.

The identification of small neoplasms or areas presenting lesions associated with previous endoscopic polypectomy is one of the major problems in laparoscopic colonic resection. The aim of our study was to evaluate the effectiveness of tattooing with Indian ink to identify the area of the colon that is the site of the lesion in order to be able to perform colonic resections with oncologically correct margins. Eighty-four patients were observed with polypoid lesions or diagnosed as presenting lesions associated with endoscopic polypectomy for which colonic resection had been recommended. Marking was performed during preoperative colonoscopy by injecting 1 ml of Indian ink solution with a sclerotherapy needle into each of the four quadrants of the colon wall. This method, which is simple to execute, invariably allowed easy identification of the site of the neoplasm and laparoscopic colon resection with correct oncological margins. In the 84 cases, we recorded only one complication (1.1%) due to a paucisymptomatic microperforation discovered during the operation. The identification of small colon lesions can be performed easily using Indian ink. It is a simple, quick method which, if performed properly, always allows the site of the lesion to be identified and is associated with a negligible rate of complications.
