One hundred fifty consecutive laparoscopic-assisted colectomies performed by a surgical team were analyzed in an attempt to define a learning curve. These colectomies performed by the Norfolk Surgical Group over a 24-month period, were divided chronologically into six groups of 25 patients each. The groups were then compared to determine if any improvement in length of procedure, complication rate, conversion rate, or length of stay developed as experience increased. Colon cancer and diverticular disease were the most common indications for surgery in all groups. Right hemicolectomy, left colectomy, and low anterior resection accounted for the majority of procedures in all groups. A significant decrease in mean operative time, from 250 min to 156 min over the first 35-50 cases was observed before leveling off at approximately 140 min for the remaining group. Intraoperative complications were low in all groups (range zero to two) and did not show any trend. There was no statistically significant difference in the conversion rate (23.3% overall) among the six groups. Length of stay decreased from 6 days in the first two groups to 5 days in the last four groups, although the difference was not statistically significant. The learning curve for laparoscopic-assisted colectomies is longer than appreciated by many surgeons, requiring as many as 35-50 procedures to decrease operative time to baseline. Complications can be kept at an acceptably low level while on the curve if a cautious approach is taken and the surgeon realizes that a prolonged operative time is not only acceptable, but appropriate during this long learning process. A conversion rate of 20-25% at any phase of the learning process may in fact represent a limitation of current technology. When combined with a low complication rate it may be the sign of a careful surgeon.
In this group of patients undergoing laparoscopic-assisted colectomies for primary colorectal malignancy, no adverse patterns of recurrence or decreased survival has been noted at 2-year follow-up when compared with standard open colorectal cancer surgery statistics. Prospective randomized studies with long-term follow-up will be required to better define the potential benefits and adverse effects of laparoscopic surgery for colorectal malignancy.
Toothbrush swallowing is an uncommon occurrence. Unlike most cases of foreign-body ingestion, there have been no cases of spontaneous passage reported. Consequently, prompt removal is recommended before complications develop. We report a case of toothbrush ingestion which failed attempted endoscopic removal. This patient was managed successfully with laparoscopic assisted removal via gastrotomy. We recommend this approach for the removal of any ingested foreign bodies when surgical intervention is indicated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
