Emergency laparoscopically assisted right hemicolectomy for obstructing right-sided colon carcinoma.

BACKGROUND: We report our preliminary experience in urgent laparoscopically assisted right hemicolectomy for obstructing right-sided colon carcinoma. MATERIALS AND METHODS: From January to April 2005, seven consecutive patients with obstructing right-sided colon carcinoma underwent emergency laparoscopically assisted right or extended right hemicolectomy. Patient demographic data, operative details, and short-term clinical outcomes were prospectively collected and analyzed. RESULTS: The median duration of obstructing symptoms prior to admission was 3 days (range, 1-6 days). Two patients underwent palliative resection and five patients underwent curative resection. The median operative time was 180 minutes (range, 125-350 minutes). There were no conversions to the open procedure. Median blood loss was 30 mL (range, negligible-300 mL). The median times to resuming diet, first bowel motion, and full ambulation were 4 days (range, 3-10 days), 5 days (range, 3-7 days), and 4 days (range, 4-5 days), respectively. The median duration of hospital stay was 7 days (range, 6-19 days). One patient with ischemic heart disease developed acute coronary syndrome postoperatively and died on postoperative day 19. The remaining patients had no complications. The median tumor length was 3.5 cm (range, 2-5 cm) and the median number of lymph nodes removed was 17 (range, 16-36). CONCLUSION: Emergency laparoscopically assisted right hemicolectomy for obstructing right-sided colon carcinoma is feasible and safe, with favorable short-term clinical outcomes and an acceptable number of lymph nodes removed.

Simultaneous laparoscopic resection of rectal cancer and liver metastasis.

Simultaneous resection of colorectal tumor and liver metastasis has been advocated because of the benefits of avoiding a second operation, reduced morbidity, shorter treatment time, and similar outcomes. We report a case of simultaneous laparoscopic resection. The operative time was 350 minutes and the estimated blood loss was 500 mL. The patient required parenteral analgesia for less than 48 hours. Flatus was passed on postoperative day 3, and a solid diet was resumed on postoperative day 5. He was fully mobile on postoperative day 4 and was discharged 3 days later. With the advance of laparoscopic technology and technique, simultaneous resection becomes an attractive option.

Laparoscopic spleen-preserving pancreatectomy for traumatic pancreatic transection: a case report.

Pancreatic transection from blunt trauma is uncommon. A 33-year-old woman suffered from blunt pancreatic trauma after a traffic accident. Computed tomography of the abdomen showed full thickness laceration through the body of the pancreas. She underwent laparoscopic spleen-preserving pancreatectomy with minimal morbidity. She remained well and without any complications 4 years after the operation.

Laparoscopic resection of rectosigmoid carcinoma: prospective randomised trial.

BACKGROUND: Although laparoscopic resection of colorectal carcinoma improves post-operative recovery, long-term survival and disease control are the determining factors for its application. We aimed to test the null hypothesis that there was no difference in survival after laparoscopic and open resection for rectosigmoid cancer. METHODS: From Sept 21, 1993, to Oct 21, 2002, 403 patients with rectosigmoid carcinoma were randomised to receive either laparoscopic assisted (n=203) or conventional open (n=200) resection of the tumour. Survival and disease-free interval were the main endpoints. Patients were last followed-up in March, 2003. Perioperative data were recorded and direct cost of operation estimated. Data were analysed by intention to treat. FINDINGS: The demographic data of the two groups were similar. After curative resection, the probabilities of survival at 5 years of the laparoscopic and open resection groups were 76.1% (SE 3.7%) and 72.9% (4.0%) respectively. The probabilities of being disease free at 5 years were 75.3% (3.7%) and 78.3% (3.7%), respectively. The operative time of the laparoscopic group was significantly longer, whereas postoperative recovery was significantly better than for the open resection group, but these benefits were at the expense of higher direct cost. The distal margin, the number of lymph nodes found in the resected specimen, overall morbidity and operative mortality did not differ between groups. INTERPRETATION: Laparoscopic resection of rectosigmoid carcinoma does not jeopardise survival and disease control of patients. The justification for adoption of laparoscopic technique would depend on the perceived value of its effectiveness in improving short-term post-operative outcomes.

A new abdominal drain insertion technique after a cirrhotic liver resection to prevent ascitic leakage.

A simple technique for inserting an abdominal drain is reported to prevent the leakage of ascitic fluid at the abdominal drainage site after a cirrhotic liver resection. This technique consists of inserting the abdominal drain through a subcutaneous tract. When the drain is then removed during the postoperative period, the pressure of the ascitic fluid that has built up in the peritoneal cavity causes pressure which thus obliterates the subcutaneous tract and thereby prevents leakage. This technique was found to be easy to perform, safe, and effective.
