Current status of an antireflux procedure in laparoscopic Heller myotomy.

BACKGROUND: Persistent dysphagia and postoperative gastroesophageal reflux (GER) are the most cited reasons for surgical failure of laparoscopic Heller myotomy. Adding an antireflux procedure to Heller myotomy has been proposed to prevent reflux. We hypothesized that an antireflux procedure added to laparoscopic Heller myotomy has little effect on preventing the symptoms or long-term sequelae of GER in achalasia patients. METHODS: We performed a meta-analysis of studies on human subjects reported in the English language literature from 1991 to 2001 years. RESULTS: An antireflux procedure accompanied laparoscopic myotomy in 15 studies with 532 patients. In 6 studies of 69 patients, no antireflux procedure was added to laparoscopic myotomy. Follow-up was available on 489 patients (92%) with partial fundoplication. The rate of GER diagnosed in pH studies was 7.9% (18 of 228 patients studied), whereas only 5.9% of patients experienced symptoms of GER (29 of 489 patients followed). Of the 69 patients without fundoplication, 47 (68%) were available for follow-up. Forty patients (85%) were studied with pH monitoring postoperatively, with 4 (10%) demonstrating reflux. Six (13%) of 47 patients had symptoms of GER. The difference in the rate of GER diagnosed in postmyotomy pH studies in wrapped and nonwrapped patients was not significant (7.9 vs 10%, respectively; p = 0.75). There was also no significant difference in the incidence of postmyotomy GER symptoms in wrapped and nonwrapped patients (5.9 vs 13% respectively; p = 0.12). CONCLUSIONS: Reflux is not necessarily eliminated with the addition of a partial fundoplication. Based on the published data, recommendations cannot be made regarding the efficacy of adding an antireflux procedure to laparoscopic Heller myotomy. Prospective randomized study is needed to clarify the role of an antireflux procedure after laparoscopic Heller myotomy.

Current status of laparoscopic ventral hernia repair.

Ventral abdominal wall hernias are a common problem for the general surgeon. Historically, the best results have been obtained with the open Rives-Stoppa approach. This is done by fixing a large piece of prosthetic mesh behind the rectus muscle. Extensive dissection is required and can lead to postoperative pain and wound complications. A laparoscopic approach allows similar mesh placement with minimal dissection. Several small comparative studies have found laparoscopic ventral hernia repair to have fewer complications, a shorter length of stay, and possibly a lower recurrence rate when compared to open mesh repair. Large prospective studies have now confirmed these findings, with recurrence rates below 4%. This is significantly lower than the best reported rates of open mesh repair. Additionally, the morbidity appears to be significantly less. This technique is easily mastered by anyone with basic laparoscopic skills and is briefly presented.

Laparoscopic diaphragmatic hernia repair.

BACKGROUND: Adult-congenital diaphragmatic hernias and chronic traumatic diaphragmatic hernias are uncommon entities that are often technically challenging to repair. There is growing experience with a minimal access approach to these defects. METHODS: We reviewed the English-language literature using a MEDLINE search for "diaphragmatic hernia" and "laparoscopy." RESULTS: We found 19 case reports of laparoscopic adult-congenital diaphragmatic hernia repair. Reported complications included two enterotomies, one of which required conversion to laparotomy. We also found 11 case reports of laparoscopic chronic traumatic diaphragmatic hernia repair, with no reported complications or recurrences. Average operative time was 98 min, and average length of stay was 4.5 days. All reports claimed that there was less postoperative pain and an earlier return to full activity with the laparoscopic approach. Herein we discuss anatomy, pathophysiology, diagnosis, method of repair, and recurrence. CONCLUSION: Adult-congenital diaphragmatic hernia and chronic traumatic diaphragmatic hernia are amenable to laparoscopic repair. Although experience is still limited, laparoscopic repair appears safe and is associated with a shorter hospital stay.

Mesh crural repair of large paraesophageal hiatal hernias.

Surgical repair is indicated in patients with paraesophageal hernias but is associated with a high recurrence rate. Our objective was to assess the safety and efficacy of mesh reinforcement of the crural closure in laparoscopic paraesophageal hernia repair. We conducted a 7-year retrospective review of all patients undergoing laparoscopic paraesophageal hernia repair with or without use of mesh. The main outcome measures were use of mesh, reason for use, age, sex, preoperative symptoms, length of operation, length of hospital stay, postoperative complications, and long-term follow-up conducted by physician interview. Twelve patients were repaired with mesh (Group A) and 12 without (Group B). Age, sex, operating time, length of hospital stay, and postoperative complications were similar in both groups. In Group A two patients required an interposition graft and ten required mesh reinforcement of the crural closure. One Group A patient developed an early recurrence requiring a reoperation, and one Group B patient developed a gastric leak where the fundus was sutured to the crura. The remainder of the patients experienced resolution of their symptoms at 2 weeks follow-up. Long-term follow-up (average 37 months) showed one Group B patient with a recurrence of reflux symptoms, but an upper gastrointestinal study showed no recurrence of hernia. All others remained asymptomatic. We conclude that the use of mesh in laparoscopic repair of large paraesophageal hernias appears safe and may reduce recurrence.
