Single site multiport umbilical laparoscopic appendicectomy versus conventional multiport laparoscopic appendicectomy in acute settings.

INTRODUCTION: Although conventional multiport laparoscopic appendicectomy (CMLA) is preferred for managing acute appendicitis, the recently developed transumbilical laparoscopic approach is rapidly gaining popularity. However, its wide dissemination seems restricted by technical/technological issues. In this regard, a newly developed method of single site multiport umbilical laparoscopic appendicectomy (SMULA) was compared prospectively with CMLA to assess the former's efficacy and the technical advantages in acute scenarios. METHODS: Overall, 430 patients were studied: 212 in the SMULA group and 218 in the CMLA group. The same surgeon performed all the procedures using routine laparoscopic instruments. The SMULA technique entailed three ports inserted directly at the umbilical mound through three distinct strategically placed mini-incisions without raising the umbilical flap. The CMLA involved the traditional three-port technique. RESULTS: Both groups were comparable in terms of demographic criteria, indications for surgery, intraoperative blood loss, time to ambulation, length of hospital stay and umbilical morbidity. Although the mean operative time was marginally longer in the SMULA group (43.35 minutes, standard deviation [SD]: 21.16 minutes) than in the CMLA group (42.28 minutes, SD: 21.41 minutes), this did not reach statistical significance. Conversely, the mean pain scores on day 0 and the cosmetic outcomes differed significantly and favoured the SMULA technique. None of the patients developed port site hernias over the follow-up period (mean 2.9 years). CONCLUSIONS: The favourable outcomes for the SMULA technique are likely to be due to the three small segregated incisions at one place and better trocar ergonomics. The SMULA technique is safe in an acute setting and may be considered of value among the options for transumbilical appendicectomy.

Laparoscopic repair of diastasis recti using the 'Venetian blinds' technique of plication with prosthetic reinforcement: a retrospective study.

BACKGROUND: Diastasis is a separation of the two recti due to various reasons, and can be measured as the 'inter-recti distance' (IRD). Surgery for diastasis is controversial, while laparoscopic repair has rarely been reported. We describe our method of laparoscopic plication-the 'Venetian blinds' technique combined with mesh reinforcement for patients with diastasis of the recti. MATERIALS AND METHODS: A total of 18 patients out of 35 that presented to us were operated. The common indications were cosmesis and discomfort while performing normal activities. Laparoscopic plication with the 'Venetian blinds' technique of the diastasis with prosthetic reinforcement was performed for all cases. RESULTS: The mean body mass index (BMI) was 28.6 kg/m(2) (range 25-32.2) and obese patients had a larger IRD. The mean operating time was 113 min (range 72-154). Minor complications were present in five (27.77%) patients. The recurrence rate after 6-48 months follow up was 0% in this series. DISCUSSION: Even though surgery for diastasis is controversial, we advocate repair for cosmesis and restoring function of the recti muscles. Our 'Venetian blinds' technique provides a solid repair and reduces the risk of seroma. The use of a prosthesis for the repair is mandatory to prevent recurrence. The adequacy of repair was assessed by measuring the IRD preoperatively and postoperatively with computed tomography (CT) scan. Laparoscopy provides all of the benefits of minimal access surgery.

Laparoscopic repair of parahiatal hernias with mesh: a retrospective study.

BACKGROUND: Parahiatal hernias are very rare and distinct entities, the diagnosis of which is never made clinically. Laparoscopic repair has been reported in the literature. We present our experiences with the laparoscopic repair of this uncommon type of hernia. PATIENTS AND METHODS: In our institute, we retrospectively identified a total of eight patients with parahiatal hernias from 1999 to 2007, of which four had primary and four had secondary defects. Laparoscopic crural repair was performed for all of the patients, fundoplication wherever indicated and meshplasty in the cases with large defects. Gastropexy was performed for the patient with volvulus. RESULTS: The male:female ratio was 5:3, with a mean age of 46 years and a mean body mass index (BMI) of 29.3 kg/m2. The mean size of the defects was 18 cm2. The mean blood loss during surgery was 50 ml, the mean operative time was 103.5 min and the mean hospital stay was 4 days. One patient had the recurrence of symptoms 1 month after surgery. There were no conversions, recurrences or mortality. DISCUSSION: Primary parahiatal hernias occur as a result of a congenital weakness and secondary defects follow hiatal surgery. The use of a mesh is advisable for large defects and defects of primary type. Secondary hernias following fundoplication do not need a redo fundoplication, but require an adequate crural repair with mesh. Laparoscopic repair of these uncommon hernias is safe, effective and provides all of the benefits of minimally invasive surgery.

Laparoscopic management of paraduodenal hernias: mesh and mesh-less repairs. A report of four cases.

BACKGROUND: Paraduodenal hernias are the most common form of internal hernias. There are few reports in the literature, with the total number of reported cases being less than 500. We report four patients with paraduodenal hernias causing intestinal obstruction. MATERIALS AND METHODS: All of the four patients with paraduodenal hernias presented with features of intestinal obstruction. A clinical diagnosis was not made in any of the cases, and computed tomography (CT) scanning was performed to confirm this. They were all successfully managed by a laparoscopic repair. RESULTS: The operating time was 55-72 mins. Postoperatively, three patients recovered uneventfully, while one patient had ileus for 3 days and, thereafter, recovered spontaneously. Hospital stay was in the range 2-6 days. There were no conversions. One patient had recurrent paraduodenal hernia, for which a laparoscopic mesh repair was successfully performed. DISCUSSION: The mechanism of the herniation is thought to be a defective rotation of the superior mesenteric vein during embryonic development. Paraduodenal hernias are not high on the list of differentials for bowel obstruction. Some form of surgery is mandatory for all cases. The inferior mesenteric vein has to be sacrificed in some cases to facilitate reduction of the hernia contents. A mesh repair is reserved for large defects and recurrent hernias. Laparoscopic repair has been infrequently reported in the literature. Based on our experience, the laparoscopic approach seems to be effective in the repair of paraduodenal hernias. It carries all of the benefits of minimal access surgery, while providing a sound repair.
