Plastic freezer bags: a cost-effective method to protect extraction sites in laparoscopic colorectal procedures?

PURPOSE: To review surgical-site infection (SSI) and retrieval-site tumor recurrence rates in laparoscopic colorectal procedures when using a plastic freezer bag as a wound protector. METHODS: Laparoscopic colorectal procedures where a plastic freezer bag used as a wound protector at the extraction site were reviewed between 1991 and 2008 from a prospectively collected database. χ test was used to compare SSI and tumor recurrence rates between groups. Costing data were obtained from the operating room supplies department. RESULTS: A total of 936 cases with 51 (5.45%) surgical-site infections were identified. SSI rates did not differ when comparing groups based on demographic factors, diagnosis, or location of procedure. Retrieval-site tumor recurrence rate was 0.21% (1/474). Cost of plastic freezer bags including sterilization ranged from $0.25 to $3. CONCLUSIONS: Plastic freezer bags as wound protectors in laparoscopic colorectal procedures are cost effective and have SSI and retrieval-site tumor recurrence rates that compare favorably to published data.

Laparoscopic colostomy reversal after a Hartmann procedure: a prospective series, literature review and an argument against laparotomy as the primary approach.

BACKGROUND: Open restoration of bowel continuity after a Hartmann procedure has been associated with significant morbidity, including anastomotic leak, incisional hernia, wound infections and inability to re-establish intestinal continuity. Few studies have examined the role of laparoscopy in performing a Hartmann reversal. The aim of this study was to review our laparoscopic Hartmann reversal (LHR) experience with an emphasis on intra- and postoperative adverse events. METHODS: A prospectively collected laparoscopic colorectal database involving 3 surgeons in 4 academic centres between 1991 and 2008 was reviewed. Factors evaluated were patient demographics, diagnosis, duration of surgery, intra- and postoperative complications, recovery of bowel function and length of stay in hospital. RESULTS: Twenty-eight consecutive patients (13 men, 15 women) with a mean age of 61.1 (standard deviation [SD] 15.3) years and a mean weight of 72.3 (SD 20.1) kg underwent LHR. The diagnosis at initial surgery was complicated diverticulitis in 19 patients (67.9%), cancer in 6 patients (21.4%) and "other" in 3 patients (10.7%). The median duration of surgery was 166.2 (SD 74.4) minutes. There were no conversions. There was 1 major intraoperative complication (bleeding; 3.6%). There were 3 postoperative complications (10.7%): 1 abscess, 1 prolonged ileus and 1 wound hematoma. Only 1 patient with an abscess required readmission. There were no observed clinical anastomotic leaks. All patients underwent successful reanastomosis. The median time to return of bowel function was 4 (interquartile range [IQR] 3-4) days. The median length of stay in hospital was 5 (IQR 3-6) days. There was no mortality. CONCLUSION: Laparoscopic colostomy reversal after a Hartmann procedure is safe and feasible in experienced hands. It is associated with low morbidity, quick return of bowel function and short stay in hospital.

Laparoscopic colectomy for complex diverticular disease: a justifiable choice?

BACKGROUND: Surgery is increasingly reserved for complicated diverticulitis. The role of laparoscopy in this context is ill defined. This study aimed to evaluate the safety, feasibility, and outcomes associated with the application of laparoscopy to an unrestricted spectrum of diverticular pathologies, with an emphasis on complicated disease. METHODS: Consecutive patients who underwent elective, urgent, or emergent laparoscopic colectomy for diverticular disease from 1991 to 2007 were analyzed from a prospectively collected database. Laparoscopy was offered to all patients presenting for surgical attention, thus minimizing selection bias. Complicated cases had abscesses, perforations, fistulas, or strictures. Uncomplicated cases had chronic or recurrent diverticulitis. Summary statistics and univariate comparisons were generated. RESULTS: A total of 183 patients were analyzed, including 39 complicated cases. The complicated cohort included 12 abscesses or perforations (31%), 18 fistulas (46%), and 11 strictures (28%). Intraoperative complications were comparable between the two groups (7.7 vs. 9.7%), although the complicated cases resulted in more conversions (23 vs. 4.2%; p = 0.0007). More than 79% of the complicated patients and 96% of the uncomplicated patients underwent unprotected primary anastomosis. Medical (23 vs. 1.4%; p < 0.0001) and surgical (28 vs. 14%; p = 0.035) complications were more frequent in the complicated group. Leak rates were acceptably low (6.5 vs. 2.2%; p = 0.23). There were no recorded deaths. Finally, the time until discharge from hospital was significantly longer in the complicated group by a median of 1 day. CONCLUSIONS: The laparoscopic management of complicated diverticular disease is feasible and appears to be safe in the hands of experts. Despite a high rate of conversion to open surgery, laparoscopy was the sole operative intervention for the majority of patients with complicated diverticular disease. Further studies are needed to allow rigorous comparison with an open control group.
