    ..The benefits of day-case TEP included less postoperative pain, a faster return to work, and a lower incidence of chronic groin pain. ..
  2. Lau H, Lam B. Management of postoperative urinary retention: a randomized trial of in-out versus overnight catheterization. ANZ J Surg. 2004;74:658-61 pubmed
    ..Indwelling catheterization for 24 h appeared to bestow no additional benefits. The incidence of urinary retention increases with age, anorectal procedures and the use of spinal anaesthesia. ..

    ..This approach is as safe and effective as open repair. Laparoscopic Graham-Steele patch repair of perforated duodenal or justapyloric ulcer is beneficial for patients without Boey's risk factors. ..
  4. Lau H, Patil N, Yuen W, Lee F. Management of peritoneal tear during endoscopic extraperitoneal inguinal hernioplasty. Surg Endosc. 2002;16:1474-7 pubmed
    ..Its occurrence significantly prolongs the length of operation. Endoscopic stapling and pretied suture loop ligation are safe and quick techniques for the closure of peritoneal tear during TEP. ..
  5. Lau H, Lee F. A prospective endoscopic study of retropubic vascular anatomy in 121 patients undergoing endoscopic extraperitoneal inguinal hernioplasty. Surg Endosc. 2003;17:1376-9 pubmed
    ..Tracing along the aberrant vessel can easily identify the obturator foramen, which is an anatomic landmark that indicates an adequate inferior dissection of the preperitoneal space. ..
  6. Lau H, Lee F. Seroma following endoscopic extraperitoneal inguinal hernioplasty. Surg Endosc. 2003;17:1773-7 pubmed
    ..Because all seromas invariably resolve, expectant treatment with observation is recommended. Inguinoscrotal hernia carries a four-fold increased risk of developing seroma after TEP. ..
  7. Lau H, Patil N. Umbilical hernia in adults. Surg Endosc. 2003;17:2016-20 pubmed
    ..Compared to Mayo repair, the laparoscopic approach confers the advantages of reduced postoperative pain, shorter hospital stay, and a diminished morbidity rate. ..

  9. Lau H, Fang C, Yuen W, Patil N. Risk factors for inguinal hernia in adult males: a case-control study. Surgery. 2007;141:262-6 pubmed
    ..Family history of hernia was the most important determinant factor for developing inguinal hernia in adult males. A male subject who has a positive family history of hernia is 8 times more likely to develop a primary inguinal hernia. ..
