Randomized trial of endoscopic sphincterotomy with balloon dilation versus endoscopic sphincterotomy alone for removal of bile duct stones.

BACKGROUND & AIMS: Limited endoscopic sphincterotomy with large balloon dilation (ESBD) is an alternative to endoscopic sphincterotomy (ES) for removing bile duct stones, but it is not clear which procedure is most effective. We compared the 2 techniques in removal of bile duct stones. METHODS: Between September 2005 and September 2011, 156 consecutive patients with suspected of having, or known to have, common bile duct stones were randomly assigned to groups that underwent ES or ESBD. Patients in the ESBD group underwent limited sphincterotomy (up to half of the sphincter) followed by balloon dilation to the size of the common bile duct or 15 mm, and patients in the ES group underwent complete sphincterotomy alone. Stones were then removed using standard techniques. The primary outcome was percentage of stones cleared, and secondary outcomes included procedural time, method of stone extraction, number of procedures required for stone clearance, morbidities and mortality within 30 days, and direct cost. RESULTS: There was no significant difference between groups in percentage of stones cleared (ES vs ESBD: 88.5% vs 89.0%). More patients in the ES group (46.2%) than the ESBD group (28.8%) required mechanical lithotripsy (P = .028), particularly for stones ≥15 mm (90.9% vs 58.1%; P = .002). Morbidities developed in 10.3% of patients in the ES group and 6.8% of patients in the ESBD group (P = .46). The cost of the hospitalization was also significantly lower in the ESBD group (P = .034). CONCLUSIONS: ESBD and ES clear bile stones with equal efficacy. However, ESBD reduces the need for mechanical lithotripsy and is less expensive; ClinicalTrials.gov number, NCT00164853.

Surgical salvage of bleeding peptic ulcers after failed therapeutic endoscopy.

BACKGROUND: The approach to salvage surgery after failed endoscopic therapy for a bleeding peptic ulcer is controversial. We aimed to compare the outcomes of salvage surgery after failed endoscopic therapy for bleeding peptic ulcers over a 10-year period. METHODS: Patients receiving salvage surgery for bleeding peptic ulcers were divided into 2 cohorts, the 1st from 1993 to 1998 and the 2nd from 1999 to 2004. The type of salvage surgery was defined as minimal if ulcer plication or an ulcerectomy was performed, and definitive if the patient received a vagotomy or gastrectomy. RESULTS: One hundred and twenty-three patients received salvage surgery in the 1st cohort, while 42 patients received surgical hemostasis for the bleeding peptic ulcer in the 2nd cohort. Patients in the 2nd cohort consisted of a larger proportion of in-hospital bleeders (cohort 1: 12.2%, cohort 2: 42.9%; p < 0.005) and had a significantly higher proportion of comorbidities. A larger number of patients received minimal surgery in cohort 2 (cohort 1: 42.3%, cohort 2: 73.8%; p < 0.005). CONCLUSIONS: With advances in therapeutic endoscopy, patients who developed failed endoscopic hemostasis are likely to be poor surgical candidates with multiple comorbidities. The approach to salvage surgery has inclined towards minimal surgery to hasten surgical hemostasis among these fragile patients.

Prophylactic ilioinguinal neurectomy in open inguinal hernia repair: a double-blind randomized controlled trial.

OBJECTIVE: We conducted a double-blinded randomized controlled trial to investigate the short- to mid-term neurosensory effect of prophylactic ilioinguinal neurectomy during Lichtenstein repair of inguinal hernia. METHOD: One hundred male patients between the age of 18 and 80 years with unilateral inguinal hernia undergoing Lichtenstein hernia repair were randomized to receive either prophylactic ilioinguinal neurectomy (group A) or ilioinguinal nerve preservation (group B) during operation. All operations were performed by surgeons specialized in hernia repair under local anesthesia or general anesthesia. The primary outcome was the incidence of chronic groin pain at 6 months. Secondary outcomes included incidence of groin numbness, postoperative sensory loss or change at the groin region, and quality of life measurement assessed by SF-36 questionnaire at 6 months. All follow-up and outcome measures were carried out by a designated occupational therapist at 1 and 6 months following surgery in a double-blinded manner. RESULTS: The incidence of chronic groin pain at 6 months was significantly lower in group A than group B (8% vs. 28.6%; P = 0.008). No significant intergroup differences were found regarding the incidence of groin numbness, postoperative sensory loss or changes at the groin region, and quality of life measurement at 6 months after the operation. CONCLUSIONS: Prophylactic ilioinguinal neurectomy significantly decreases the incidence of chronic groin pain after Lichtenstein hernia repair without added morbidities. It should be considered as a routine surgical step during the operation.
