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

BACKGROUNDnEpinephrine 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.nnnMETHODSnThe 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.nnnRESULTSnOne 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.nnnCONCLUSIONnEpinephrine 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.

Routine use of laparoscopic repair for perforated peptic ulcer

Laparoscopic repair of perforated peptic ulcer was reported in 1990 but has not gained wide acceptance. The aim of this study was to evaluate the safety and efficacy of laparoscopic repair for perforated peptic ulcer in routine clinical practice.

Outpatient laparoscopic cholecystectomy in Hong Kong: patient acceptance.

The authors performed a prospective evaluation of 60 Hong Kong Chinese patients with symptomatic gallstones and gallbladder polyps undergoing outpatient laparoscopic cholecystectomy in a regional hospital in Hong Kong from March 1996 to May 1998 to determine the feasibility, satisfaction, and acceptance of this procedure among Chinese patients. Patients with American Society of Anesthesiologists grade I and II gallstones or polyps were selected. Exclusion criteria included 1) history of upper abdominal operations, attacks of acute cholecystitis, cholangitis, or pancreatitis; 2) abnormal liver function; and 3) ultrasonographic evidence of contracted gallbladder, thickened gallbladder wall, dilated common bile duct, or common bile duct stones. Patients discharged at 5:00 pm on the day of cholecystectomy were defined as having undergone outpatient procedure. Patients were asked about procedure acceptance, rated on a scale of 1 to 10 (best), using a standardized questionnaire 4 weeks after operation. The study included 21 men and 39 women with mean age of 40.5 years (range, 27–59). There were no conversions to open procedures in the series. There were 6 (10%) unanticipated postoperative hospital admissions; all patients were discharged on the first postoperative day. Another patient was readmitted 3 days after operation because of a common bile duct stone. Overall patient acceptance of outpatient laparoscopic cholecystectomy was good, with a mean score of 8.6 of 10. Thirteen patients (22%) expressed dissatisfaction with being discharged earlier than they had expected, and 9 (15%) would have preferred inpatient care. Forty-eight patients (80%) resumed full daily activities by the first postoperative day; the remaining 12 did so by the end of the first week. Among the 44 working patients, only 4 (9%) resumed full duty within the first postoperative week; 29 (66%) did so by the second week and the remaining 11 (25%) returned to work after the third week. By selecting appropriate subjects, outpatient laparoscopic cholecystectomy is feasible and highly accepted among Hong Kong Chinese patients. Approximately one quarter of the patients preferred a longer postoperative stay or inpatient care.

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.

Laparoscopy-assisted surgical management of obscure gastrointestinal bleeding secondary to Meckel's diverticulum in a pediatric patient: case report and review of literature.

Despite advances in endoscopy and imaging, acute gastrointestinal (GI) bleeding of obscure origin in children presents a challenge to pediatric gastroenterologist. Bleeding Meckels diverticulum (MD) commonly presents with acute episode of lower GI bleeding. A conventional diagnostic algorithm includes endoscopy, technetium 99m pertechnetate scintigraphy, angiography, and exploratory laparotomy. The advent of minimal access surgery prompts the use of laparoscopy for children with obscure GI bleeding. Laparoscopy assists in the diagnosis and can offer definitive treatment of patients with MD. Herein, we report a case of pediatric GI bleeding of obscure origin associated with MD that was successfully diagnosed and managed via laparoscopy. This article updates the current management for pediatric patients with obscure GI bleeding and the role of laparoscopy in the management of MD.

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.

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.
