Laparoscopic cholecystectomy: day-care versus clinical observation.

OBJECTIVE To determine the feasibility and desirability of laparoscopic cholecystectomy (LC) in day-care versus LC with clinical observation. SUMMARY BACKGROUND DATA Laparoscopic cholecystectomy has been performed regularly as outpatient surgery in patients with uncomplicated gallstone disease in the United States, but this has not been generally accepted in Europe. The main objections are the risk of early severe complications (bleeding) or other reasons for readmission, and the argument that patients might feel safer when observed for one night. Quality-of-life differences hitherto have not been investigated. METHODS Eighty patients (American Society of Anesthesiology [ASA] I/II) with symptomatic gallstones were randomized to receive LC either in day-care or with clinical observation. Complications, (re)admissions, consultations of general practitioners or the day-care center within 4 days after surgery, use of pain medication, quality of life, convalescence period, time off from professional activities, and treatment preference were assessed. The respective costs of day-care and clinical observation were determined. RESULTS Of the 37 patients assigned to the day-care group who underwent elective surgery, 92% were discharged successfully after an observation period of 5.7+/-0.2 hours. The remainder of the patients in this group were admitted to the hospital and clinically observed for 24 hours. For the 37 patients in the clinical observation group who underwent elective surgery, the observation time after surgery was 31+/-3 hours. Three patients in the day-care group and one patient in the clinical observation group had complications after surgery. None of the patients in either group consulted a general practitioner or the hospital during the first week after surgery. Use of pain medication was comparable in both groups over the first 48 hours after surgery. There were no differences in pain and other quality-of-life indicators between the groups during the 6 weeks of follow-up. Of the patients in the day-care group, 92% preferred day-care to clinical observation. The same percentage of patients in the clinical observation group preferred at least 24 hours of observation to day-care. Costs for the day-care patients were substantially lower (approximately

Because no differences were found with respect to the other outcomes, day-care is the preferred treatment in most ASA I and II patients because it is less expensive.

Value of laparoscopic ultrasonography in staging of proximal bile duct tumors

Bariatric surgery ameliorates obesity‐associated diseases, resulting in psychological and social benefits. Long‐term studies of its effects on quality of life (QOL) assessed with well established instruments are lacking. This prospective study investigated the long‐term effects of gastric banding on health‐related QOL using an obesity‐specific validated measure.

Cytology of peritoneal lavage performed during staging laparoscopy for gastrointestinal malignancies: is it useful?

The additional value of laparoscopic ultrasonography was evaluated prospectively in 35 patients undergoing diagnostic laparoscopy for a suspected potentially resectable proximal bile duct tumor. Findings were compared with transabdominal ultrasonography, laparoscopy, surgery, and pathology. Laparoscopic ultrasonography was able to visualize the presence and origin of small bile duct tumors or stones and small liver metastases, which could not be seen or could be visualized only doubtfully by ultrasonography and laparoscopy. Laparoscopic ultrasonography was more useful in staging of small tumors of the gallbladder or proximal common bile duct than in staging bifurcation (Klatskin) tumors. Additional information provided by laparoscopic ultrasonography led to a change in diagnosis or tumor stage in eight patients (23%) and to avoidance of laparotomy in three patients (9%).

Hand-assisted laparoscopic splenectomy

OBJECTIVE To evaluate the potential benefit of cytology of the peritoneal lavage obtained during diagnostic laparoscopy for staging gastrointestinal (GI) malignancies. SUMMARY BACKGROUND DATA Peritoneal lavage is a simple procedure that can be performed during laparotomy for GI tumors. Tumor cells in the lavage fluid are thought to indicate intraperitoneal tumor seeding and to have a negative effect on survival. For this reason, peritoneal lavage is frequently added to diagnostic laparoscopy for staging GI malignancies. METHODS Patients who underwent peritoneal lavage during laparoscopic staging for GI malignancies between June 1992 and September 1997 were included. Lavage fluids were stained using Giemsa and Papanicolaou methods. Cytology results were correlated with the presence of metastases and tumor ingrowth found during laparoscopy and with survival. RESULTS Cytology of peritoneal lavage was performed in 449 patients. Tumor cells were found in 28 patients (6%): 8/87 with an esophageal tumor, 2/32 with liver metastases, 11/72 with a proximal bile duct tumor, 7/236 with a periampullary tumor, and none in 7 and 15 patients with a primary liver tumor or pancreatic body or tail tumor, respectively. In 19 of the 28 patients (68%) in whom tumor cells were found, metastatic disease was detected during laparoscopy, and 3 of the 28 patients had a false-positive (n = 1) or a misleading positive (n = 2) lavage result. Therefore, lavage was beneficial in only 6/449 patients (1.3%); in these patients, the lavage result changed the assessment of tumor stage and adequately predicted irresectable disease. Univariate analysis showed a significant survival difference between patients in whom lavage detected tumor cells and those in whom it did not, but multivariate analysis revealed that these survival differences were caused by metastatic or ingrowing disease. CONCLUSION Cytology of peritoneal lavage with conventional staining should no longer be performed during laparoscopic staging of GI malignancies because it provides an additional benefit in only 1.3% of patients and has limited prognostic value for survival in this group of patients.

Laparoscopy and laparoscopic ultrasonography in staging carcinoma of the gastric cardia.

Abstract. Laparoscopic splenectomy is performed routinely in patients with small and moderately enlarged spleens at specialized centers. Large spleens are difficult to handle laparoscopically and hand-assisted laparoscopic splenectomy might facilitate the procedure through enhanced vascular control, easier retraction and manipulation, manual guidance of endostaplers, and clip appliers. A technique of hand-assisted laparoscopic splenectomy is described.

Randomized clinical trial of perioperative selective decontamination of the digestive tract versus placebo in elective gastrointestinal surgery

Objective: To investigate the role of diagnostic laparoscopy and laparoscopic ultrasonography in the staging of carcinoma of the gastric cardia that is involving the distal oesophagus. Design: Retrospective consecutive case series. Setting: Tertiary care centre, The Netherlands. Subjects: 48 patients (34 men and 14 women, median age 63 years, range 39-84) who presented with tumours of the gastric cardia that involved the distal oesophagus and in whom non-invasive staging had not shown unresectable locoregional disease or distant metastases. Interventions: In addition to laparoscopy and laparoscopic ultrasonography, biopsy of all suspected lesions outside the area of potential resection. Main outcome measures: Number of patients in whom the findings obviated the need for exploratory laparotomy. Results: There were no complications related to the laparoscopy. The investigation showed distant metastases (which were histologically verified) in 11 patients (23%, 95% confidence interval (CI) 16 to 30). These pa...

Comparison of laparoscopic and transabdominal ultrasonography in staging of cancer of the pancreatic head region

This randomized clinical trial analysed the effect of perioperative selective decontamination of the digestive tract (SDD) in elective gastrointestinal surgery on postoperative infectious complications and leakage.

Laparoscopic ultrasonography for abdominal tumor staging: technical aspects and imaging findings

The value of laparoscopic ultrasonography in the staging of cancer of the pancreatic head region was compared prospectively to that of transabdominal ultrasonography. Eighty patients underwent LUS, after ultrasonography had shown normal Doppler findings of portal vessels and no signs of metastatic disease. Presence of hepatic or lymph node metastases and vascular tumor infiltration were evaluated in 74 and 48 patients, respectively. Laparoscopic ultrasonography showed liver metastases in 10 patients (14%). Specificity and positive predictive value for the laparoscopic technique determining vascular ingrowth were 97% and 92%, respectively, versus 89% and 77% by sonography in patients with normal Doppler findings (difference not statistically significant). Laparoscopic ultrasonography has shown improved detection of hepatic metastases compared to sonography, but it still must prove its value, as compared to noninvasive methods, in local staging.

Laparoscopic ultrasonography for abdominal tumor staging

Abstract. Since 1992 diagnostic laparoscopy combined with laparoscopic ultrasonography has been performed in our center in more than 300 patients for staging of tumors of the liver, bile ducts, pancreas, esophagus, and gastric cardia. In this article our experience with laparoscopic ultrasonography for abdominal tumor staging is described, with particular attention for the technical aspects, imaging findings, limitations, and pitfalls.
