Long-term symptom control of gastro-oesophageal reflux disease 12 years after laparoscopic Nissen or 180° anterior partial fundoplication in a randomized clinical trial.

BACKGROUND: Laparoscopic 180° anterior fundoplication has been shown to achieve similar reflux control to Nissen fundoplication, with fewer side-effects, up to 5 years. However, there is a paucity of long-term follow-up data on this technique and antireflux surgery in general. This study reports 12-year outcomes of a double-blind RCT comparing laparoscopic Nissen versus 180° laparoscopic anterior fundoplication for gastro-oesophageal reflux disease (GORD). METHODS: Patients with proven GORD were randomized to laparoscopic Nissen or 180° anterior fundoplication. The 12-year outcome measures included reflux control, dysphagia, gas-related symptoms and patient satisfaction. Measures included scores on a visual analogue scale, a validated Dakkak score for dysphagia and Visick scores. RESULTS: Of the initial 163 patients randomized (Nissen 84, anterior 79), 90 (55·2 per cent) completed 12-year follow-up (Nissen 52, anterior 38). There were no differences in heartburn, dysphagia, gas-related symptoms, patient satisfaction or surgical reintervention rate. Use of acid-suppressing drugs was less common after Nissen than after 180° anterior fundoplication: four of 52 (8 per cent) and 11 of 38 (29 per cent) respectively (P = 0·008). The proportion of patients with absent or only mild symptoms was slightly higher after Nissen fundoplication: 45 of 50 (90 per cent) versus 28 of 38 (74 per cent) (P = 0·044). CONCLUSION: The two surgical procedures provided similar control of heartburn and post-fundoplication symptoms, with similar patient satisfaction and reoperation rates on long-term follow-up.

Outcome of laparoscopic inguinal hernia repair in a South African private practice setting.

OBJECTIVE: The aim of this study was to determine the recurrence and complication rates of laparoscopic inguinal hernia repair performed in a private practice in Cape Town. DESIGN AND SUBJECTS: An unselected cohort of 507 patients who underwent laparoscopic totally extraperitoneal (TEP) inguinal hernia repair before September 2005 were included in this study, thus ensuring a minimum 5-year follow-up. Patient demographic data, clinical notes, operating notes and outpatient follow-up notes were studied. Patients were interviewed telephonically regarding hernia recurrence, chronic pain and technique preference if they had previously undergone an open repair. All data collected were recorded on an electronic spreadsheet. The primary outcome parameter was recurrence. The secondary outcome parameters were postoperative and long-term complications. RESULTS: Of the 507 patients, 267 were contactable telephonically. There were 384 hernia repairs with a mean follow-up of 8.8 years. There were 9 recurrences (2.3%). The overall complication rate was 7.9%. Two per cent of patients suffered from chronic groin pain with gradual improvement since surgery. Sixteen per cent of patients had had previous open repair of an inguinal hernia, either on the ipsilateral or the contralateral side, and all judged the open repair to have been more painful. CONCLUSIONS: The recurrence and complication rates for laparoscopic TEP inguinal hernia repair in this practice are low and comparable to the best reported series. There is a low incidence of persistent postoperative pain with the laparoscopic technique, and it is the technique preferred by patients who previously underwent an open repair.

Surgery for colonic cancer in HNPCC: total vs segmental colectomy.

AIM: The high reported risk of metachronous colon cancer (MCC) in hereditary nonpolyposis colorectal cancer (HNPCC) has led some authors to recommend total colectomy (TC) as the preferred operation for primary colon cancer, but this remains controversial. No previous study has compared survival after TC with segmental colectomy (SC) in HNPCC. The aim of this study was to determine the risk of developing MCC in patients with genetically proven HNPCC after SC or TC for cancer, and to compare their long-term survival. METHOD: This is a prospective cohort study of all patients referred to our unit between 1995 and 2009 with a proven germline mismatch repair gene defect, who had undergone a resection for adenocarcinoma of the colon with curative intent. All patients were offered annual endoscopic surveillance. RESULTS: Of 60 patients in the study, 39 had TC as their initial surgery and 21 had SC. After 6 years follow up, MCC occurred in eight (21%) SC patients and in none of the TC patients (P = 0.048). The risk of developing MCC after SC was 20% at 5 years. Colorectal cancer-specific survival was better in TC patients (P = 0.048) but overall survival of the two groups was similar (P = 0.29). CONCLUSION: Patients with HNPCC have a significant risk of MCC after SC. This is eliminated by performing TC as the primary operation for colonic cancer.

Randomized double-blind trial of laparoscopic Nissen fundoplication versus anterior partial fundoplication.

BACKGROUND: This double-blind, randomized study compared outcomes of laparoscopic Nissen total fundoplication and anterior partial fundoplication carried out by a single surgeon in a private practice. METHODS: All patients with proven gastro-oesophageal reflux disease, regardless of motility, presenting for laparoscopic antireflux surgery were randomized to either Nissen total or anterior partial fundoplication. Primary outcome measures were dysphagia and abolition of reflux. Secondary outcome measures were Visick scores, bloating, patient satisfaction and reoperation rate. RESULTS: Complete follow-up was available for 161 (98.8 per cent) of 163 patients (84 Nissen, 79 anterior). There were no differences in mean heartburn scores between groups. Recurrent reflux was observed in ten patients after anterior fundoplication, but none after the Nissen procedure. Dysphagia scores for both liquids and solids were lower after anterior fundoplication. Four patients had persistent troublesome dysphagia after Nissen fundoplication compared with none after anterior fundoplication. There were no differences between groups in postoperative bloating. The overall reoperation rate at 2 years was 7 per cent, all achieved laparoscopically. CONCLUSION: Nissen fundoplication cured reflux in all patients up to 2 years, but 5 per cent required revisional surgery. Recurrent reflux was more common after anterior fundoplication, but dysphagia was rare. Patient satisfaction was excellent in both groups. Revisional laparoscopic surgery was safe and usually successful.

Palliative surgery for acute bowel obstruction caused by Kaposi's sarcoma in a patient with AIDS.

Patients with human immunodeficiency virus (HIV) infection or acquired immune deficiency syndrome (AIDS) can present with acute abdominal surgical problems, either with intra-abdominal opportunistic infection as a result of their immunosuppression, or with associated malignancies. We report a 39-year-old man who developed intermittent nausea and vomiting, which was originally thought to be a side-effect of the chemotherapy he was receiving for facial Kaposi's sarcoma. However, he was found to have intraperitoneal Kaposi's sarcoma causing small bowel obstruction, which was successfully excised at laparotomy. There were no perioperative complications despite AIDS-related respiratory disease. The patient remained free of abdominal symptoms until his death. HIV infections or AIDS alone should not be contraindications to surgery for such problems, as careful patient selection can yield good results and significantly improve quality of life.

Radical excision of multifocal anal intraepithelial neoplasia: report of a case.

PURPOSE: The aim of this study was to describe the technique of radical excision of multifocal anal intraepithelial neoplasia and discuss controversial issues surrounding the management of this condition. METHOD: We describe the case of a 31-year-old female with previous vulval warts, vulval squamous carcinoma, and recent immunosuppression who had widespread anal intraepithelial neoplasia excised, and the resulting defect was split-skin grafted, including the anal canal. RESULTS: Excision and split-skin grafting was successful in removing the disease and left a satisfactory cosmetic and functional result. CONCLUSION: Diffuse, high-grade, anal intraepithelial neoplasia is rare. Excision of these lesions remains controversial but may be the best option.

Efficacy of anterior, posterior and total fundoplication in an experimental model.

BACKGROUND: This study examined the effect of different types of laparoscopic fundoplication on an incompetent lower oesophageal sphincter to test their effectiveness at preventing gastro-oesophageal reflux in the early postoperative period. METHODS: An experimental porcine model was used. Initial oesophageal myotomy ensured an incompetent lower oesophageal sphincter with free reflux of 'intragastric fluid'. Anterior, posterior or total fundoplication was then performed laparoscopically in 15 laboratory pigs (five in each group). Fundoplication competence and efficacy were determined 2 weeks after laparoscopic antireflux surgery by inflating the stomach with liquid through a gastrostomy cannula. Some animals were also studied at 4 and 6 weeks. Lower oesophageal sphincter pressure was determined using a water-perfused oesophageal manometry catheter incorporating a Dent sleeve. RESULTS: All three types of fundoplication produced similar increases in postoperative resting lower oesophageal sphincter pressure and restored adequate competence to the gastro-oesophageal junction. CONCLUSION: All three variants of laparoscopic fundoplication restore gastro-oesophageal competence in the early postoperative period.

Prospective double-blind randomized trial of laparoscopic Nissen fundoplication with division and without division of short gastric vessels.

OBJECTIVE: To determine whether division of the short gastric vessels (SGVs) and full mobilization of the gastric fundus is necessary to reduce the incidence of postoperative dysphagia and other adverse sequelae of laparoscopic Nissen fundoplication. SUMMARY BACKGROUND DATA: Based on historical and uncontrolled studies, division of the SGVs has been advocated during laparoscopic Nissen fundoplication to improve postoperative clinical outcomes. However, this modification has not been evaluated in a large prospective randomized trial. METHODS: One hundred two patients with proven gastroesophageal reflux disease presenting for laparoscopic Nissen fundoplication were prospectively randomized to undergo fundoplication with (52 patients) or without (50 patients) division of the SGVs. Patients with esophageal motility disorders, patients requiring a concurrent abdominal procedure, and patients who had undergone previous antireflux surgery were excluded. Patients were blinded to the postoperative status of their SGVs. Clinical assessment was performed by a blinded independent investigator who used multiple standardized clinical grading systems to assess dysphagia, heartburn, and patient satisfaction 1, 3, and 6 months after surgery. Objective measurement of lower esophageal sphincter pressure, esophageal emptying time, and distal esophageal acid exposure and radiologic assessment of postoperative anatomy were also performed. RESULTS: Operating time was increased by 40 minutes (median 65 vs. 105) by vessel division. Perioperative outcomes and complications, postoperative dysphagia, relief of heartburn, and overall satisfaction were not improved by dividing the SGVs. Lower esophageal sphincter pressure, acid exposure, and esophageal emptying times were similar for the two groups. CONCLUSION: Division of the SGVs during laparoscopic Nissen fundoplication did not improve any clinical or objective postoperative outcome.
