ABSTRACT

BACKGROUND: Many patients who have surgery for acute cholecystitis receive postoperative antibiotic prophylaxis, with the intent to reduce infectious complications. There is, however, no evidence that extending antibiotics beyond a single perioperative dose is advantageous. This study aimed to determine the effect of extended antibiotic prophylaxis on infectious complications in patients with mild acute cholecystitis undergoing cholecystectomy. METHODS: For this randomized controlled non-inferiority trial, adult patients with mild acute calculous cholecystitis undergoing cholecystectomy at six major teaching hospitals in the Netherlands, between April 2012 and September 2014, were assessed for eligibility. Patients were randomized to either a single preoperative dose of cefazolin (2000 mg), or antibiotic prophylaxis for 3 days after surgery (intravenous cefuroxime 750 mg plus metronidazole 500 mg, three times daily), in addition to the single dose. The primary endpoint was rate of infectious complications within 30 days after operation. RESULTS: In the intention-to-treat analysis, three of 77 patients (4 per cent) in the extended antibiotic group and three of 73 (4 per cent) in the standard prophylaxis group developed postoperative infectious complications (absolute difference 0·2 (95 per cent c.i. -8·2 to 8·9) per cent). Based on a margin of 5 per cent, non-inferiority of standard prophylaxis compared with extended prophylaxis was not proven. Median length of hospital stay was 3 days in the extended antibiotic group and 1 day in the standard prophylaxis group. CONCLUSION: Standard single-dose antibiotic prophylaxis did not lead to an increase in postoperative infectious complications in patients with mild acute cholecystitis undergoing cholecystectomy.

ABSTRACT

AIM: The study aimed to describe the serosal microcirculation of the human bowel using sidestream dark field imaging, a microscopic technique using polarized light to visualize erythrocytes through capillaries. We also compared its feasibility to the current practice of sublingual microcirculatory assessment. METHOD: In 17 patients sidestream dark field measurements were performed during gastrointestinal surgery. Microcirculatory parameters like microvascular flow index (MFI), proportion of perfused vessels (PPV), perfused vessel density (PVD) and total vessel density (TVD) were determined for every patient, sublingually and on the bowel serosa. RESULTS: Sixty measurements were done on the bowel of which eight (13%) were excluded, five owing to too much bowel peristalsis and three because of pressure artefacts. Image stability was in favour of sublingual measurements [pixel loss per image, bowel 145 (95% CI 126-164) vs sublingual 55 (95% CI 41-68); P < 0.001] and time to acquire a stable image [bowel 96 s (95% CI 63-129) vs. sublingual 46 s (95% CI 29-64); P = 0.013]. No difference in the MFI was observed [bowel 2.9 (interquartile range 2.87-2.95) vs sublingual 3.0 (interquartile range 2.91-3.0); P = 0.081]. There was a difference in the PPV [bowel 95% (95% CI 94-96) vs sublingual 97% (95% CI 97-99); P < 0.001], PVD [bowel 12.9 mm/mm2 (95% CI 11.1-14.8) vs sublingual 17.4 mm/mm2 (95% CI 15.6-19.1); P = 0.003] and the TVD [bowel 13.6 mm/mm2 (95% CI 11.6-15.6) vs sublingual 17.7 mm/mm2 (95% CI 16.0-19.4); P = 0.008]. CONCLUSION: Sidestream dark field imaging is a very promising technique for bowel microcirculatory visualization and assessment. It is comparable to sublingual assessment and the analysis produces a similar outcome with slightly differing anatomical features.

ABSTRACT

BACKGROUND: During laparoscopic right hemicolectomy, most surgeons perform an extracorporeal anastomosis. A totally laparoscopic procedure with intracorporeal anastomosis may improve cosmesis because midline- or paraumbilical incisions can be avoided. Here, we investigate the safety of an intracorporeal anastomosis from a technical and oncological perspective. METHODS: All patients who underwent right hemicolectomy with intracorporeal anastomosis between 2003-2011 were retrospectively analyzed. Parameters were duration of surgery, intraoperative blood loss, mortality and morbidity. Adequacy of oncologic resections was scored by resectional margins and number of harvested lymph nodes. RESULTS: A total of 162 patients were included with a median age of 69 years (IQR60-76). The duration of surgery was 100 minutes (80-120) and intraoperative blood loss was 30 mL (10-100). Hundred-twenty patients (74%) underwent an oncologic resection. Number of harvested lymph nodes was 12 (9-18). RO-resection was achieved in 100%. Four patients died (2.5%). Postoperative complications were: anastomotic leakage (3.1%; n = 5), ileus (4.9%; n = 8), abscesses (2.5% ; n = 4), wound infection (3.1% ; n = 5) and cardiopulmonary complications (10.5% ; n = 17). Duration of oncological follow-up was 2.5 years (1.3-4.6). Local recurrence and overall survival rates at two years were 0.8% and 85.4%, respectively. CONCLUSION: Right hemicolectomy with intracorporeal anastomosis is a technically and oncologically safe procedure with acceptable operating time and low mortality.
