Laparoscopic versus open repair for strangulated groin hernias: 188 cases over 4 years.

INTRODUCTION: Currently transabdominal pre-peritoneal and totally extraperitoneal repairs are the two standard laparoscopic approaches for groin hernia repair. However, they are still largely reserved for uncomplicated elective cases. To determine whether laparoscopic groin hernia repair can achieve similar results for acute strangulated hernias as laparoscopic cholecystectomy for acute cholecystitis, we analyzed and compared the results of emergency laparoscopic surgery and open repair for strangulated groin hernias performed by our team over the past 4 years. METHODS: This is a retrospective analysis of prospectively collected data. We analyzed the results of patients admitted between January 2007 and January 2011 who were diagnosed with acute strangulated groin hernia and underwent emergency open or laparoscopic hernia repair during the same admission. Patients' demographic details, mode of presentation, type of hernia, intraoperative findings, operative time, postoperative course and complications were compared. RESULTS: In total, 188 patients fulfilled the criteria for emergency surgical repair of strangulated groin hernias; 57 received laparoscopic and 131 received open repairs. The mean operative time was 79.82 ± 29.571 min and 80.75 ± 35.161 min, respectively. More laparotomies were performed in the open group (19 vs 0). The wound infection rate was significantly higher in the open group (12 vs 0). The mean hospital stay was shorter in the laparoscopic group (4.39 days vs 7.34 days). There was no mesh infection in either group. Recurrence occurred one case in the laparoscopic group and in three cases in the open group. CONCLUSIONS: Emergency laparoscopic repair for strangulated groin hernias is feasible and appears to have a lower morbidity relative to open repair. Further study should be performed to evaluate its full potential.

Single-incision transabdominal preperitoneal and totally extraperitoneal repair for inguinal hernia: early experience from a single center in Asia.

INTRODUCTION: Laparoscopic inguinal hernia repair is currently one of the most commonly performed minimally invasive surgical procedures. In recent years, single-incision operations have been developed to further reduce the invasiveness of the surgery. Herein, we report our early experience with single-incision laparoscopic inguinal hernia repair in Asia, with both the transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) approaches. METHODS: This is a retrospective review of prospectively collected data on a cohort of consecutive patients with inguinal hernia who underwent single-incision laparoscopic inguinal hernia repair in a minimal access surgical center in Hong Kong between January 2010 and January 2011. RESULTS: Our cohort consists of 15 patients who underwent single-incision laparoscopic inguinal hernia; 13 were unilateral and two were bilateral hernias. The mean age was 59.8 years old (range, 28-74 years). The overall mean operative time was 59.53 min (range, 25-120 min). For unilateral hernia repair, the mean operative time was 56 min (range, 25-75 min) and 48.5 min (range, 41-55 min) for TAPP and TEP, respectively. In all cases single-incision laparoscopic hernia repair was successfully performed, no additional trocars were required, and there were no conversions to conventional laparoscopic or open inguinal hernia repair. All patients were discharged on the same day as the procedure. CONCLUSION: Single-incision laparoscopic inguinal hernia is feasible in both TEP and TAPP approaches. The procedure should be performed by laparoscopic surgeons with a high level of experience in single-incision surgery. Further randomized trials should be performed to evaluate the full potential and clinical application of single-incision TAPP and TEP.

Stapled technique for acute thrombosed hemorrhoids: a randomized, controlled trial with long-term results.

PURPOSE: This study was designed to compare stapled vs. conventional hemorrhoidectomy for patients with acute thrombosed hemorrhoids. METHODS: Forty-one patients with acute thrombosed hemorrhoids were randomized into: 1) stapled hemorrhoidectomy (PPH group; n = 21), and 2) open hemorrhoidectomy (open group; n = 20). Emergency surgery was performed with perioperative data and complications were recorded. Patients were followed up by independent assessors to evaluate pain, recurrence, continence function, and satisfaction at regular intervals. RESULTS: The median follow-up for the PPH group and open group were 59 and 56 weeks, respectively. There was no significant difference in terms of the hospital stay, complication rate, and continence function; however, the mean pain intensity in the first postoperative week was significantly less in the PPH group (4.1 vs. 5.7, P = 0.02). Patients in the PPH group recovered significantly faster in terms of the time to become analgesic-free (4 vs. 8.5 days, P < 0.01), time to become pain-free (9 vs. 20.5 days, P = 0.01), resumption of work (7 vs. 12.5 days, P = 0.01), and time for complete wound healing (2 vs. 4 weeks, P < 0.01). On long-term follow-up, significantly fewer patients in the PPH group complained of recurrent symptoms (0 vs. 5, P = 0.02). The overall symptom improvement and patients' satisfaction were significantly better in the PPH group (90 vs. 80 percent, P = 0.03 and +3 vs. +2, P < 0.01 respectively). CONCLUSIONS: Stapled hemorrhoidectomy is safe and effective for acute thrombosed hemorrhoids. Similar to elective stapled procedure, emergency stapled excision has greater short-term benefits compared with conventional excision: diminished pain, faster recovery, and earlier return to work. Long-term results and satisfaction were excellent.
