Laparoscopic vs open colectomy for sigmoid diverticulitis: a prospective comparative study in the elderly.
BACKGROUND: The aim of this prospective comparative study was to assess the outcome of laparoscopic and open colectomy for sigmoid diverticulitis in patients aged >/=75 years. METHODS: From January 1993 to December 1998, all patients 75 years of age and older undergoing an elective colectomy for sigmoid diverticulitis were included in the study. The patients were divided into the following two groups: group 1 (n = 22) consisted of patients who underwent a laparoscopic procedure; group 2 (n = 24) consisted of patients who underwent an open procedure. RESULTS: In group 1, there were 12 women and 10 men with a mean age of 77.2 years (range, 75-82); in group 2, there were 14 women and 10 men with a mean age of 78 years (range, 76-84) (p = 0.37). There was no difference between the groups in ASA classification. The operative time was shorter in group 2 (136 vs 234 mins). The postoperative period during which parenteral analgesics were required (5.4 vs 8.2 days, p = 0.001), postoperative morbidity (18% vs 50%, p = 0.02), postoperative length of hospital stay (13.1 vs 20.2 days, p = 0.003), and the inpatient rehabilitation (6 vs 15 patients, p = 0.01) were significantly shorter for group 1 than for group 2. There were no perioperative deaths. The conversion rate was 9% in group 1. CONCLUSION: The data from the present study suggest that laparoscopic colectomy for sigmoid diverticulitis can be applied safely to older patients with fewer complication, less pain, shorter hospital stay, and a more rapid return to preoperative activity levels than that seen with open colorectal resection.

Cancer of the gallbladder associated with pancreaticobiliary maljunction without bile duct dilatation in a european patient.
A rare case of pancreaticobiliary maljunction (PBM) without dilatation of the biliary tract (DBT) associated with gallbladder carcinoma is described herein. A 62-year-old European woman with a long history of right upper abdominal pain was diagnosed as having PBM without DBT by endoscopic retrograde cholangiopancreatography and other examinations. Excision of the gallbladder and biliary duct with a Roux-en-Y hepaticojejunostomy was performed, and subsequent pathological examination of the surgical specimen showed a well differentiated adenocarcinoma of the gallbladder. She had no clinical symptoms for 58 months postoperatively. PBM allows reflux of pancreatic juice into the biliary tract. Recent findings support the idea that epithelial hyperplasia plays an important role in gallbladder carcinogenesis with PBM, and also support the concept that gene mutations are involved in the carcinogenesis of biliary epithelium in patients with PBM. For these reasons, we advocate that resection of the extrahepatic biliary tract in PBM patients without bile duct dilatation, rather than cholecystectomy alone, is the treatment of choice for preventing bile duct carcinoma.

[Nuclear magnetic resonance cholangiography in biliary disease. Prospective study in 60 patients].
PURPOSE: The aim of this prospective study was to evaluate a new MR cholangiography sequence, with thick slices, single shot fast spin echo (SSFSE) in biliary obstructive diseases. PATIENTS AND METHODS: This study included 60 patients (36 males and 24 females, mean age: 69 years) with cholestatic syndrome and suspected bile duct obstruction. All patients were prospectively investigated with MR cholangiography using SSFSE sequence with thick slices. The gold standard was ERCP (n = 47), per cutaneous cholangiography (n = 1), and surgical intervention (n = 12). According to this gold standard, 22 patients had obstructive gallstones, 23 had neoplastic obstruction, eight had inflammatory or postoperative stenosis and 7 had normal bile ducts. RESULTS: The sensitivity and specificity of MR cholangiography were 100 and 94% in the diagnosis of obstructive gallstones, and 95 and 97% in the diagnosis of neoplastic obstruction, respectively. A good agreement was observed between MR cholangiography and the gold standard, regardless of the site of obstruction (range of kappa value: 0.79-1). CONCLUSION: MR cholangiography with SSFSE sequence is an effective and easy technique. Acquisition of thick slices in a very short time (< 2 sec) limits cardiorespiratory artefacts and eliminates the need for post-processing.

[Percutaneous cholecystostomy for acute cholecystitis in high-risk patients].
AIM OF THE STUDY: The aim of this retrospective study was to report the results of percutaneous cholecystostomy in a selected group of high-risk patients with contraindications of general anesthesia. PATIENTS AND METHODS: From October 1995 to December 1999, a percutaneous cholecystostomy was performed in 29 patients with acute cholecystitis. There were 20 women and nine men with a mean age of 80.6 years (range: 59 to 95 years). All the patients were ASA III (N = 23) or ASA IV (N = 6). Ultrasound-guided percutaneous cholecystostomy was performed in 24 cases and computed tomography-guided cholecystostomy in five cases. RESULTS: Percutaneous cholecystostomy was easily performed in 28 cases; there was one failed procedure. The drainage was not efficient in three patients who were operated on with one postoperative death of a patient who had a necrotic cholecystitis. There was no mortality in relation with cholecystostomy. One patient died at day 15 from myocardia infarction. The morbidity rate was 3.4% (one case). Postoperative length of hospital stay was 13 days (range: 7-30 days). The duration of the entire procedure ranged from 9 to 60 days (mean: 20 days). The mean follow-up of patients was 17 months (range: 4-40 months). One patient had recurrent acute cholecystitis and another one had angiocholitis; two patients underwent delayed elective laparoscopic cholecystectomy; 20 patients remained asymptomatic and 16 were still alive at the time of this study (13 with biliary stones and three without). CONCLUSION: Percutaneous cholecystostomy is a valuable alternative procedure for high-risk patients with acute cholecystitis. It's a safe and usually effective procedure without mortality and with a low morbidity. Whenever possible, percutaneous cholecystostomy should be followed by laparoscopic cholecystectomy.

[Laparoscopic cholecystectomy in the treatment of acute cholecystitis. Prospective non-randomized study].
OBJECTIVES: To evaluate the results of laparoscopic cholecystectomy in patients with acute cholecystitis and to determine the optimal timing. PATIENTS AND METHODS: From January 1993 to December 1999, 168 patients (91 women and 77 men with a mean age of 57.3 years) underwent laparoscopic cholecystectomy for acute cholecystitis confirmed by histopathological examination. Patients were divided into 2 groups (similar in age and ASA classification): group 1 (106 patients) underwent laparoscopic cholecystectomy within 3 days after the onset of symptoms of acute cholecystitis and group 2 (62 patients) underwent laparoscopic cholecystectomy after 3 days. RESULTS: There was no death. Conversion rates were 30.9%. Surgery lasted 141.3 min, postoperative morbidity was 12.5%, and the postoperative length of hospital stay was 6.9 days. The conversion rates in patients who underwent surgery before and 3 days after the onset of symptoms were respectively 21.7% and 46.7% (P=0.0007). There was no statistical difference between early and delayed surgery for time to surgery and postoperative complications. On the other hand, the total hospital stay was significantly shorter in group 1. CONCLUSION: Laparoscopic cholecystectomy for acute cholecystitis is safe and associated with a shorter postoperative stay, a lesser morbidity and a lesser mortality compared to "open" surgery. Laparoscopic cholecystectomy should be carried out soon as the diagnostic of acute cholecystitis is established and preferably before 3 days after the onset of the symptoms. Early laparoscopic cholecystectomy allows a reduction of the conversion rate and a reduction of total hospital stay that are medical and economic benefits.

Laparoscopic cholecystectomy in the elderly: a prospective study.
BACKGROUND: The aim of this prospective study was to determine the feasibility and the complications or benefits of laparoscopic cholecystectomy (LC) in the patients older than 75 years. METHODS: From January 1992 to July 1998, a total of 863 patients underwent LC, of these patients, 102 patients older than 75 years (group 1) were compared with 761 younger patients (group 2). RESULTS: In the elderly, 35.3% were at high surgical risk (American Society of Anesthesiology [ASA] III and ASA IV). The conversion rate to open cholecystectomy (OC) was 21.6%. The mean length of hospital stay was 6.9 days for both laparoscopy and conversion. Morbidity and mortality rates were 13.7% and 1%, respectively. No patient suffered intraoperative cardiopulmonary complication, and there was no reoperation in the elderly. CONCLUSIONS: Elderly patients experience more complications and longer duration of hospital stay than younger patients. However, our results compare favorably with other OC studies in elderly patients.

Laparoscopic colectomy for sigmoid diverticulitis: a prospective study in the elderly.
BACKGROUND/AIMS: The aim of this prospective study was to determine the feasibility and the complications or benefits of laparoscopic colectomy for sigmoid diverticulitis in patients aged 75 years or more. METHODOLOGY: From January 1993 to December 1999, 85 patients underwent an elective colectomy for sigmoid diverticulitis. Twenty-two patients over 75-years old (group 1) were compared to 63 younger patients (group 2). RESULTS: In group 1, there were 12 women and 10 men, with a mean age of 77.2 years (range: 75-82); In group 2, there were 35 women and 28 men, with a mean age of 53.7 years (range: 38-74) (P = 1.10-14). The operative time was shorter in group 2 (183 vs. 234 min). There was no difference between the 2 groups with regard to the postoperative period during which parenteral analgesics were required (5.4 vs. 5.2 days, P = 0.48) and the postoperative morbidity (18% vs. 14%, P = 0.06). Postoperative length of hospital stay (13.1 vs. 8.8 days, P = 0.003) was shorter in group 2 than in group 1. There was no perioperative mortality. Conversion rate was 9% (group 1) and 6% (group 2) (P = 0.6). CONCLUSIONS: In summary, data from the present study suggest that laparoscopic colectomy for sigmoid diverticulitis can be applied safely to older patients with fewer complications, less pain, shorter hospital stay and a rapid return to preoperative activity levels.

Intraoperative colonic lavage with primary anastomosis vs. Hartmann's procedure for perforated diverticular disease of the colon: a consecutive study.
BACKGROUND/AIMS: The ideal treatment for complicated diverticulitis is still controversial. The Hartmann's procedure remains the favored option in patients with acute complicated sigmoid disease but there has been increasing interest in primary resection and anastomosis with intraoperative colonic lavage. A prospective study was carried out on 71 patients with peritonitis, comparing primary resection with intraoperative colonic lavage, and Hartmann's procedure. METHODOLOGY: Between January 1994 and September 1999, 71 patients underwent emergency laparotomy for diverticular peritonitis. Primary resection and anastomosis with intraoperative colonic lavage was performed in 29 patients (group I) and Hartmann's procedure in 42 patients (group II). All data were collected on standardized forms. RESULTS: There were no differences between the two groups according to clinical features, biology, severity of disease and operative delay. The mortality rate in group I and group II was, respectively, 7 and 10% (P = 0.6). The incidence of postoperative complication was higher after Hartmann's procedure (P < 0.05). The mean hospital stay was significantly longer for the Hartmann's procedure compared to primary resection with intraoperative colonic lavage. CONCLUSIONS: Primary resection with intraoperative colonic lavage compares favorably with Hartmann's procedure for local or diffuse purulent peritonitis in complicated diverticulitis. It should be an alternative to the Hartmann's procedure in stercoral peritonitis.
