Laparoscopic cholecystectomy for acute cholecystitis: the evolving trend in an institution.

BACKGROUND: Laparoscopic cholecystectomy (LC) is the gold standard for symptomatic cholecystolithiasis. Technical maturation and advances in instrumentation have enabled the application of this procedure for acute cholecystitis (AC). We review the evolving role of LC for AC in our institution. METHODS: A retrospective study was conducted of patients who received LC for AC between January 1994 and June 2001. Patients' demographics, clinical findings and perioperative outcomes were evaluated. RESULTS: There were 140 men and 141 women with a mean age of 56.9 years (range, 23-89 years). Two hundred and eighteen of these patients underwent successful LC. There were 63 conversions (22.4%) for uncertain anatomy and difficult dissection (41), gangrenous or perforated gallbladder (16) and bleeding (6). The conversion rates as stratified to surgeon's seniority were 25.1%, 22.8% and 9.7% for registrar, senior registrar and consultant, respectively. The mean operative time was 84.3 minutes (range, 30-255 minutes) and the mean postoperative stay was 5.8 days (range, 1-35 days). The overall complication rate was 11.6%, including two bile duct injuries and two perioperative deaths. CONCLUSION: LC for AC is safe and effective and associated with a low incidence of complications when routinely applied by surgical residents. The conversion rate is related to operators' surgical experience.

Therapeutic minilaparoscopy for perforated peptic ulcer.

Laparoscopic repair for perforated peptic ulcer has been demonstrated to be safe and effective. We report our initial experience of applying therapeutic minilaparoscopy for peptic ulcer perforation. Five patients with perforated peptic ulcers managed by a team of surgeons using minilaparoscopy are reported. There were no conversions, perioperative morbidity, or mortality. Patients experienced minimal wound pain and required minimal parental analgesia. The access wound scars were hardly discernable at 3-month followup. Therapeutic minilaparoscopy is technically feasible for patients with perforated peptic ulcer and is associated with satisfactory clinical and cosmetic outcome.

Vagotomy and gastrojejunostomy for benign gastric outlet obstruction.

OBJECTIVE: Peptic-ulcer-induced gastric outlet obstruction is an indication for operative intervention. The advent of minimal access surgery allows the conventional open procedure to be performed via laparoscopy. PATIENTS AND METHODS: From 1996 to 2000, 15 consecutive patients, aged 29 to 75 years, underwent laparoscopic truncal vagotomy and gastrojejunostomy for gastric outlet obstruction. Perioperative data and longterm followup results were analyzed. RESULTS: There were no conversions or perioperative mortality. The mean operative time was 114 minutes. Patients required on average 1 dose of intramuscular pethidine for analgesia. Eleven patients were discharge by postoperative day 10; the remaining 4 patients had delayed gastric emptying which settled with conservative treatment. With an average followup period of 80 months, patients were classified as Visick I (n = 7), II (n = 5), III (n = 1), and IV (n = 2). CONCLUSION: Laparoscopic truncal vagotomy and gastrojejunostomy is technically feasible for patients with benign gastric outlet obstruction and is associated with satisfactory perioperative and longterm outcome.

Randomized controlled trial comparing epinephrine injection plus heat probe coagulation versus epinephrine injection plus argon plasma coagulation for bleeding peptic ulcers.

BACKGROUND: Epinephrine injection with heat probe coagulation is an effective treatment for bleeding peptic ulcer. Few studies have investigated the efficacy of dual therapy with epinephrine injection plus either heat probe or argon plasma coagulation for high-risk bleeding peptic ulcers. This study compared epinephrine injection plus heat probe coagulation to epinephrine injection plus argon plasma coagulation for the treatment of high-risk bleeding peptic ulcers. METHODS: The study design was prospective, randomized, and controlled. Patients with actively bleeding peptic ulcers, ulcers with adherent clots, or ulcers with nonbleeding visible vessels were randomly assigned to epinephrine injection plus heat probe coagulation or epinephrine injection plus argon plasma coagulation. Patients with previous gastric surgery, malignant ulcers, and unidentifiable ulcers because of torrential bleeding were excluded. The primary outcome measure was recurrence of bleeding. Secondary outcome measures were initial hemostasis, endoscopic procedure duration, number of patients requiring surgery, mortality within 30 days, and ulcer status at 8 week follow-up endoscopy. RESULTS: One hundred ninety-two patients were enrolled; 7 with malignant ulcers were excluded after randomization. One hundred eighty-five cases were analyzed, 97 in the heat probe group and 88 in the argon plasma coagulation group. Patient demographics and ulcer characteristics were comparable between the groups. There was no significant difference in terms of initial hemostasis (95.9% vs. 97.7%), frequency of recurrent bleeding (21.6% vs. 17.0%), requirement for emergency surgery (9.3% vs. 4.5%), mean number of units of blood transfused (2.4 vs. 1.7 units), mean hospital stay (8.2 vs. 7.0 days), and hospital mortality (6.2% vs. 5.7%). Sixty (61.8%) patients in the heat probe group and 52 (52.9%) in the argon plasma coagulation group underwent endoscopy at 8 weeks. There was no significant difference between these groups in the relative frequency of nonhealing ulcer at 8 weeks. CONCLUSION: Epinephrine injection plus argon plasma coagulation is as safe and effective as epinephrine injection plus heat probe coagulation in the treatment of patients with high-risk bleeding peptic ulcers.

Laparoscopic repair of iatrogenic endoscopic perforated peptic ulcer.

Iatrogenic perforation is an uncommon but inevitable complication of endoscopy. Laparotomy has been the standard treatment for pyloroduodenal perforations caused by endoscopy. Laparoscopic repair is a well-documented treatment modality for spontaneously perforated peptic ulcer. We report our successful laparoscopic suture repair of perforations sustained during upper gastrointestinal endoscopy in two high-risk elderly patients.

Laparoscopic management of omental torsion secondary to an occult inguinal hernia.

Torsion of the greater omentum is an uncommon surgical emergency. Most of the reported cases have been primary omental torsion with infarction, in which the underlying cause is largely unknown. Right-sided abdominal symptoms are the predominant complaint. Left-sided omental torsion is rather infrequent, and the preoperative diagnosis is extremely difficult. We report a case of omental torsion secondary to an occult left indirect inguinal hernia that was successfully diagnosed and managed laparoscopically.
