Laparoscopic central pancreatectomy.

BACKGROUND: The role of mini-invasive surgery in pancreatic surgery is still being debated. Indications and results are still controversial. Only a few centers in the world report on laparoscopic pancreatic resections. With the aim of improving the use of minimally invasive surgery, we have devised a novel laparoscopic procedure for surgical treatment of neuroendocrine tumor of the neck of the pancreas. METHODS: A central laparoscopic pancreatic resection was successfully performed. The pancreatic resection was performed using the harmonic scalpel. The duct was isolated and transected. The proximal duct stump was closed by an endoscopic stitch. The pancreaticojejunostomy was intracorporeally performed using a Roux-en-Y loop. RESULTS: Histologic findings showed a well differentiated neuroendocrine tumor. Operating time was 330 minutes and blood loss 300 mL. The postoperative course was uneventful. CONCLUSIONS: Laparoscopic central pancreatectomy is a feasible and safe procedure. The minimally invasive approach ensures an adequate treatment despite requiring the expertise of highly skilled laparoscopic surgeons.

Temperature control and recovery of bowel function after laparoscopic or laparotomic colorectal surgery in patients receiving combined epidural/general anesthesia and postoperative epidural analgesia.

UNLABELLED: We compared the effects of a laparoscopic (n = 23) versus laparotomic (n = 21) technique for major abdominal surgery on temperature control in 44 patients undergoing colorectal surgery during a combined epidural/general anesthesia. A thoracic epidural block up to T4 was induced with 6-10 mL of 0.75% ropivacaine; general anesthesia was induced with thiopental, fentanyl, and atracurium IV and maintained with isoflurane. Core temperature was measured with a bladder probe and recorded every 15 min after the induction. In both groups, core temperature decreased to 35.2 degrees C (range, 34 degrees C-36 degrees C) at the end of surgery. After surgery, normothermia returned after 75 min (60-120 min) in the Laparoscopy group and 60 min (45-180 min) in the Laparotomy group (P = 0.56). No differences in postanesthesia care unit discharge time were reported between the two groups. The degree of pain during coughing was smaller after laparoscopy than laparotomy from the 24th to the 72nd observation times (P < 0.01). Morphine consumption was 22 mg (2-65 mg) in the Laparotomy group and 5 mg (0-45 mg) in the Laparoscopy group (P = 0.02). The time to first flatus was shorter after laparoscopy (24 h [16-72 h]) than laparotomy (72 h [26-96 h]) (P = 0.0005), and the first intake of clear liquid occurred after 48 h (24-72 h) in the Laparoscopy group and after 96 h (90-96 h) in the Laparotomy group (P = 0.0005). Although laparoscopic surgery provides positive effects on the degree of postoperative pain and recovery of bowel function, the reduction in heat loss produced by minimizing bowel exposure with laparoscopic surgery does not compensate for the anesthesia-related effects on temperature control, and active patient warming must also be used with laparoscopic techniques. IMPLICATIONS: This prospective, randomized, controlled study demonstrates that laparoscopic colorectal surgery results in less postoperative pain and earlier recovery of bowel function than conventional laparotomy but does not reduce the risk for perioperative hypothermia. Accordingly, active warming must be provided to patients also during laparoscopic procedures.

[Laparoscopic pancreatic resection: preliminary experience].

The aim of the study was to evaluate the results of laparoscopic pancreatectomy for pancreatic tumours. Four women and three men underwent laparoscopic pancreatectomy and were recruited into the study retrospectively over the period from June 2002 to February 2004. Pancreaticoduodenectomy (n = 4), intermediate pancreatectomy (n = 1) and distal pancreatic resection with splenectomy (n = 2) were successfully performed. Operative mortality was nil. The postoperative morbidity included two low-output pancreatic leaks. Mean operating time, blood loss and hospital stay were 342 minutes, 289 mL and 14 days, respectively. The pathological diagnosis was ductal adenocarcinoma in one, neuroendocrine tumour in five and metastatic melanoma in one. All patients are still well after a median follow-up of 7 months (range: 1-20 months). The patients appear to benefit from laparoscopic pancreatectomy for pancreatic tumours. The minimally invasive approach ensures adequate treatment but requires the expertise of highly skilled laparoscopic surgeons.

Operative and long-term results after one-stage surgery for obstructing colonic cancer.

BACKGROUND/AIMS: To analyze retrospectively the operative results and five-year survival after single-stage resection and primary anastomosis for right- or left-sided colonic malignant obstruction. METHODOLOGY: From 1994 to 2002, 83 patients with acute obstruction due to primary cancer underwent a one-stage procedure, 36 (43.3%) for cancer of the right and 47 (56.7%) of the left colon. Of the 47 patients with left acute obstruction, 45 were treated with intraoperative colonic on-table lavage for decompression and wash-out before resection and anastomosis. Long-term survival was compared with the outcome of 369 patients with colonic cancer without obstruction 144 (39%) right and 225 (61%) left. RESULTS: Overall operative morbidity and mortality were 25.3% and 6%, respectively. Overall anastomotic leakage rate was 6%. Kaplan-Meier curves showed five-year survival rates poorer for patients operated on for obstructing malignancy than those observed for patients without obstruction (p=0.0001, Log-Rank test), obstructing malignancy was associated with more advanced age (p<0.0005) and staging of the cancer. CONCLUSIONS: One-stage resection and primary anastomosis can be applied to the majority of patients with malignant colonic obstruction and it allows achieving excellent operative results. Obstructing colonic cancer proved to be associated to a worse long-term survival.
