Laparoscopic surgery for the management of obstruction of the gastric outlet and small bowel following previous laparotomy for major upper gastrointestinal resection or cancer palliation: a new concept.

BACKGROUND: Surgical relief of gastric outlet obstruction (GOO) or small bowel obstruction in patients who had undergone major resection or palliative bypass surgery for malignancy is conventionally achieved at a laparotomy. The potential role of minimally invasive surgery in the management of these complications has not been previously explored. METHODS: Between 2003 and 2004, 4 consecutive patients, age range 37 to 72 years, where admitted with gastric outlet or proximal small bowel obstruction following previous open surgery for suspected intra-abdominal malignancy, under the care of one surgeon. The respective past histories of these patients were recurrent GOO and concomitant distal biliary obstruction following a previous open gastric bypass elsewhere for metastatic pancreatic head cancer; persistent adhesive small bowel obstruction following radical gastrectomy for gastric cancer; GOO secondary to intra-abdominal recurrence 6 months after hepatobiliary resection for hilar cholangiocarcinoma; and GOO following previous pancreatico-duodenectomy for suspected pancreatic head cancer. Their respective surgical management consisted of a laparoscopic re-do gastric bypass and concomitant cholecystojejunostomy; adhesiolysis and revision of the Roux-en-Y enteric anastomosis; a Devine exclusion gastroenterostomy; and resection and refashioning of the gastroenterostomy. RESULTS: There were no conversions to open surgery and no postoperative complications. The median operating time was 240 minutes (range, 145 to 300 minutes). Oral free fluid intake was resumed on postoperative day (POD) 1, while diet was resumed between POD 2 and 4. The median postoperative hospital stay was 15.5 days (range, 14 to 25 days). CONCLUSION: Previous laparotomy and major resection or palliation of malignancy do not preclude the application of the laparoscopic approach for the management of upper gastrointestinal obstruction. Laparoscopic adhesiolysis and revision of enteroenteric and gastroenteric anastomoses are feasible management options in the hands of those experienced with complex laparoscopic surgery.

Predictors of duration of postoperative hospital stay in patients undergoing advanced laparoscopic surgery.

The expansion of the indications for laparoscopic surgery to include high-risk patient, acute and malignant pathology, and more complex procedures may prolong the hospital stay. Cox multiple stepwise regression analysis model was employed to determine independent predictors of prolonged postoperative hospital stay (more than 3 days) following advanced laparoscopic procedures among 10 variables. Some 130 patients had undergone advanced laparoscopic surgical procedures between November 2000 and August 2003. The median postoperative hospital stay was 3 days (interquartile range 2-5), and 81 patients (62.3%) were discharged within 3 days of surgery. The independent predictors of prolonged postoperative hospital stay were ASA score of 3 or 4 (odds ratio [OR] = 4.610, P = 0.0002) and preoperative hospital stay (OR = 0.151 per day, P = 0.001). Independent predictors of duration of preoperative hospital stay were emergency admission to hospital (OR = 9.516, 95% CI 5.770-13.261, P < 0.0001) and an underlying malignant pathology (OR = 7.948, 95% CI 3.623-12.273, P = 0.0004). Advanced laparoscopic surgery is associated with a short postoperative hospital stay in the majority of patients. Prolongation of the postoperative hospital stay (more than 3 days) may be expected if the patient had been in the hospital with an acute or malignant disease for more than 6 days prior to surgery and in patients with high comorbidity. The duration of surgery has no impact on the duration of the postoperative hospital stay.

An "all 5-mm ports" selective approach to laparoscopic cholecystectomy, appendectomy, and anti-reflux surgery.

Laparoscopic appendectomy, cholecystectomy, or anti-reflux procedures are conventionally performed with the use of one and often two 10/12-mm ports. While needlescopic or micropuncture laparoscopic procedures reduce postoperative pain, they invariably involve the use of one 10/12-mm port and the instruments applied have their ergo-dynamic shortcomings. Between September 2002 and March 2003, we have attempted an "all 5-mm ports" approach in 49 laparoscopic procedures, which included 18 of 59 laparoscopic cholecystectomies (31%), 26 diagnostic laparoscopies for suspected appendicitis (of which we proceeded to a laparoscopic appendectomy in 17 patients), and in the last 5 of 9 laparoscopic Nissen fundoplications. Conversion of one of the 5-mm ports to a 10-mm port was required in 5 of the 18 (28%) laparoscopic cholecystectomies and in 6 of the 17 (35%) laparoscopic appendectomies to facilitate organ retrieval in patients with large gallstones (>5 mm in diameter) and in obese patients with fatty mesoappendix. There were no conversions to open surgery. No significant differences in the operating time between the laparoscopic procedures performed by the all 5-mm ports approach or the conventional approach were observed. No intraoperative or postoperative complications occurred in this series. The "all 5-mm ports" approach to laparoscopic cholecystectomy and appendectomy in selected patients and to laparoscopic fundoplication appears feasible and safe. A randomised comparison between this approach and the conventional laparoscopic approach to elective cholecystectomy and fundoplication in which two of the ports employed are of the 10-mm diameter is warranted.
