Laparoscopic colorectal resection does not reduce incisional hernia rates when compared with open colorectal resection

Background Laparoscopic colorectal surgery has been reported to have some advantages compared with open surgery. The purpose of this study was to evaluate the incidence of incisional hernias after elective open colorectal resection versus laparoscopic colorectal resection. Methods The study group consisted of 104 patients who underwent elective colorectal resection or reversal of a Hartmann’s procedure between November 2003 and March 2005. Baseline data were prospectively recorded on all patients. All were examined by an independent observer for evidence of incisional hernia after they had reached a minimum follow up of one year. Results At a median follow up of 22 (17–26) months, nine patients had died and 95 were reviewed. Of these, 32 underwent laparoscopic resection while 63 had open surgery. Patients were well matched for all baseline characteristics. The median length of the wound in the laparoscopic group was 9 cm (IQR: 8–11 cm) while in the open group it was 20.8 cm (IQR: 17–24 cm). There was no significant difference in incisional hernia rates between the groups (3 vs. 10, p = 0.52) or in those who had symptoms from their hernia (p = 0.773). Conclusions Laparoscopic colorectal resection does not appear to reduce incisional hernia rates when compared with open surgery. Large randomised trials are required to confirm these findings.     

The Sigma-trial protocol: a prospective double-blind multi-centre comparison of laparoscopic versus open elective sigmoid resection in patients with symptomatic diverticulitis

Backround  

Diverticulosis is a common disease in the western society with an incidence of 33–66%. 10–25% of these patients will develop diverticulitis. In order to prevent a high-risk acute operation it is advised to perform elective sigmoid resection after two episodes of diverticulitis in the elderly patient or after one episode in the younger (< 50 years) patient. Open sigmoid resection is still the gold standard, but laparoscopic colon resections seem to have certain advantages over open procedures. On the other hand, a double blind investigation has never been performed. The Sigma-trial is designed to evaluate the presumed advantages of laparoscopic over open sigmoid resections in patients with symptomatic diverticulitis.     

Laparoscopic versus open incisional hernia repair

Background Incisional hernia is a common complication of abdominal surgery, and it is often a source of morbidity and high costs for health care. This is a case-control study to compare laparoscopic versus anterior-open incisional hernia repair. Methods 170 patients with incisional hernia were enrolled in this study between September 2001 and December 2004. Of these, 85 underwent anterior-open repair (open group: OG), and 85 underwent laparoscopic repair (laparoscopic group: LG). The clinical outcome was determined by a median follow-up of 24.0 months for LG and OG. Results No difference was noticed between the two groups in age, American Society of Anesthesiologists (ASA) score, body mass index (BMI), and incisional hernia diameter. Mean operative time was 61.0 min for LG patients and 150.9 min for OG patients (p < .05). Mean hospitalization was 2.7 days for LG patients and 9.9 days for OG patients (p < .05). Mean return to work was 13 days (range, 6–15 days) in LG patients and 25 days (range, 16–30 days) in OG patients. Complications occurred in 16.4 % of LG patients and 29.4 % of OG patients, with a relapse rate of 2.3% in LG and 1.1% in OG patients. Conclusions Short-term results indicate that laparoscopic incisional hernia repair is associated with a shorter operative time and hospitalization, a faster return to work, and a lower incidence of wound infections and major complications compared to the anterior-open procedure. Further studies and longer follow-up are required to confirm these findings.     

Entirely laparoscopic radical gastrectomy for adenocarcinoma: lymph node yield and resection margins

Background  Laparoscopic assisted distal gastrectomy for adenocarcinoma has been widely reported from Japan and Korea but there are sparse data for Western patients. This study aimed to describe and compare the perioperative outcomes and pathological staging for consecutive patients who underwent laparoscopic or open gastrectomy by a single surgeon in the UK. Methods  During the period from April 2005 to May, 2007, patients with gastric adenocarcinoma were selected for open or laparoscopic resection at the discretion of the surgeon. Gastric resections for gastrointestinal stromal tumour (GIST) or benign disease were excluded. Laparoscopic gastrectomy was performed entirely laparoscopically with intracorporeal anastomosis, followed by specimen retrieval via a suprapubic incision. Results  There were 21 men and 8 women, median age 75 years (range 45–88 years), with American Anaesthesiology Association scores of 3 or 4 in 19 patients. Gastrectomy was performed laparoscopically in 18 patients (62%; total gastrectomy, 6 patients) or open in 11 patients (total gastrectomy, 7). Five laparoscopic gastrectomies were converted to open procedures, three patients had re-laparoscopy and one patient had subsequent laparotomy. As compared with open gastrectomy, laparoscopic resection had longer operation time and similar length of hospital stay. There was one postoperative mortality in each group. There was similar lymph node retrieval for laparoscopic or open resection [23 (range 10–44) versus 26 (8–95), respectively; p = 0.40], with inadequate lymphadenectomy (<15 nodes) in two laparoscopic cases and one open case. R1 resection was limited to patients with pT3 disease (laparoscopic, 4; open, 2). Conclusions  Perioperative outcomes were similar for laparoscopic or open gastrectomy. Lymphadenectomy was adequate in 89% of laparoscopic gastrectomies. pT3 tumours were at risk of noncurative resection, as described in large Western series of open gastrectomy.     

Open vs laparoscopic partial posterior fundoplication

Objective This study compares outcomes following open and laparoscopic partial posterior fundoplication for gastroesophageal reflux disease concerning perioperative course, postoperative complications, symptomatic relief, recurrent disease, and the need for reinterventional surgery. Methods A prospective randomized trial was performed. Pre- and postoperative testing included endoscopy, esophageal function testing, patient questionnaire, and clinical assessment. Patients were followed for three years. Materials Ninety-three patients were randomized to open and 99 to laparoscopic surgery. Results Complication rates were higher, and length of stay (LOS) [5 (3–36) vs 3 (1–12) days] and time off work [42 (12–76) vs 28 (0–108) days] was longer in the open group (p < 0.01). Early side effects and recurrences were more common (p < 0.05) in the laparoscopic group. One patient in the open group and 8 patients in the laparoscopic group required surgery for recurrent disease and 7 patients required surgery for incisional hernias after open surgery. Overall, at one and three years, there were no differences in patient-assessed satisfactory outcome (93.5/93.5 vs 88.8/90.8%) or reflux control (p = 0.53) between the open and laparoscopic groups. Conclusions The finding of fewer general complications, shorter length of stay and recovery, similar need for reoperations, and comparable 3-year outcomes, makes the laparoscopic approach the primary choice when considering surgical options for the treatment of gastroesophageal reflux disease (GERD).     

Laparoscopic colectomy is associated with decreased postoperative gastrointestinal dysfunction

Background  Major abdominal surgery is associated with early postoperative gastrointestinal dysfunction, which may lead to abdominal distention and vomiting, requiring nasogastric (NGT) tube insertion. This study aimed to compare the rates of early postoperative NGT insertion after open and laparoscopic colorectal surgery. Methods  A retrospective chart review was performed for patients who underwent colorectal surgery with removal of the NGT at completion of surgery. Patients who required reinsertion of the NGT in the early postoperative course were identified. The reinsertion rate for patients who underwent laparoscopic surgery was compared with that for the open group. Results  There were 103 patients in the open group and 227 in the laparoscopic group. In the laparoscopic group, 42 patients underwent conversion to open surgery. Reinsertion of the NGT was required for 18.4% of the patients in the open group, compared with 8.6% of the patients for whom the procedure was completed laparoscopically (p = 0.02). Conversion to open surgery resulted in a reinsertion rate of 17%. Conclusion  Laparoscopic colorectal surgery is associated with decreased postoperative gastrointestinal dysfunction, resulting in a significantly lower NGT reinsertion rate. Presented as a poster at the annual meeting of the Society of American Gastrointestinal and Endoscopic Surgeons, (SAGES), Dallas, Texas, 26–29 April 2006, and at the annual meeting of the European Society for Endoscopic Surgeons (EAES), Berlin, Germany, 13–16 September 2006.     

Staged hernia repair preceded by gastric bypass for the treatment of morbidly obese patients with complex ventral hernias

Background  Obesity may be the most predominant risk factor for recurrence following ventral hernia repair. This is secondary to significantly increased intra-abdominal pressures, higher rates of wound complications, and the technical difficulties encountered due to obesity. Medically managed weight loss prior to surgery is difficult. One potential strategy is to provide a surgical means to correct patient weight prior to hernia repair. Methods  After institutional review board approval, we reviewed the medical records of all patients who underwent gastric bypass surgery prior to the definitive repair of a complex ventral hernia at our medical center. Results  Twenty-seven morbidly obese patients with an average of 3.7 (range 1–10) failed ventral hernia repairs underwent gastric bypass prior to definitive ventral hernia repair. Twenty-two of the gastric bypasses were open operations and five were laparoscopic. The patients’ average pre-bypass body mass index (BMI) was 51 kg/m² (range 39–69 kg/m²), which decreased to an average of 33 kg/m² (range 25–37 kg/m²) at the time of hernia repair at a mean of 1.3 years (range 0.9–3.1 years) after gastric bypass. Seven patients had hernia repair at the same time as their gastric bypass (four sutured, three biologic mesh), all of which recurred. Of the 27 patients, 19 had an open hernia repair and eight had a laparoscopic repair. Panniculectomy was performed concurrently in 15 patients who had an open repair. Prior to formal hernia repair, one patient required an urgent operation to repair a hernia incarceration and a small-bowel obstruction 11 months after gastric bypass. The average hernia and mesh size was 203 cm² (range 24–1,350 cm²) and 1,040 cm² (range 400–2,700 cm²), respectively. There have been no recurrences at an average follow-up of 20 months (range 2 months–5 years). Conclusion  Gastric bypass prior to staged ventral hernia repair in morbidly obese patients with complex ventral hernias is a safe and definitive method to effect weight loss and facilitate a durable hernia repair with a possible reduced risk of recurrence. No outside funding was received for this study.     

Laparoscopic versus open liver resection of hepatic neoplasms: comparative analysis of short-term results

Background  Concerns have been raised regarding outcome after laparoscopic resection of hepatic neoplasms. This prospective study compared morbidity and adequacy of surgical margins in laparoscopic (LLR) versus open liver resection (OLR). Methods  Outcome in 359 consecutive patients [male/female ratio 187/172; median age 60 years (range 18–84 years)] who underwent partial hepatectomy was analysed. Cirrhosis was present in 32 patients and preoperative chemotherapy was administered in 141 patients. Comparative analyses were performed using propensity scores for all and for matched patients (n = 76 per group). Results  Complications occurred in 68/250 (27.2%) patients after OLR and in 6/109 (5.5%) after LLR [odds ratio (OR) 0.16; 95% confidence interval (CI) 0.07–0.37; p < 0.0001]. Median intraoperative blood loss was 500 ml (range 10–7,000 ml) in OLR and 100 ml (range 5–4,000 ml) in LLR (p < 0.0001). Postoperative hospital stay was 8 days (range 0–155 days) after OLR and 6 days (range 0–41 days) after LLR (p < 0.0001). In patients treated for liver malignancy, the surgical resection margin was positive on histopathological examination in 5/237 after OLR and in 1/77 after LLR. The magnitude of the resection margin was 7.5 mm (range 0–45 mm) in OLR and 10.0 mm (range 0–30 mm) in LLR (p = 0.087). Conclusions  LLR for hepatic neoplasms seems to be noninferior to OLR regarding adequacy of surgical margins, and superior to OLR regarding short-term postoperative outcome.     

Open randomized clinical trial of laparoscopic versus open incisional hernia repair

Background  Incisional hernia is a common complication following abdominal surgery. Although the use of prosthetics has decreased recurrence rates, the standard open approach is still unsatisfactory. Laparoscopic techniques are an attempt to provide similar outcomes with the advantages of minimally invasive surgery. Methods  Open randomized controlled clinical trial with follow-up at 1, 2, 3, 7, and 15 days, and 1, 3, and 12 months from hernia repair. The study was carried out in the surgery departments of three general hospitals of the Valencia Health Agency. Objectives  To compare laparoscopic with anterior open repair using health-related quality of life outcomes as main endpoints. Results  Eighty-four patients with incisional hernia were randomly allocated to an open group (OG) (n = 39) or to a laparoscopic group (LG) (n = 45). Seventy-four patients completed 1-year follow up. Mean length of stay and time to oral intake were similar between groups. Operative time was 32 min longer in the LG (p < 0.001). Conversion rate was 11%. The local complication rate was superior in the LG (33.3% versus 5.2%) (p < 0.001). Recurrence rate at 1 year (7.9% versus 9.7%) was similar in the two groups. There were no significant differences in the pain scores or the EQ5D tariffs between the two groups during follow-up. Conclusions  Laparoscopic incisional hernia repair does not seem to be a better procedure than the open anterior technique in terms of operative time, hospitalization, complications, pain or quality of life.     

Clinical study of laparoscopic versus open hepatectomy for malignant liver tumors

Background  The number of reported laparoscopic hepatectomies for liver malignancy is increasing, but comparative data on the survival outcomes between the patients who have undergone laparoscopic hepatectomy versus open surgery are still lacking. Methods  We compared 31 laparoscopic liver resections with 31 open liver resections in a pair-matched retrospective analysis with the aim of evaluating the intraoperative hazards, recovery, and survival outcomes of these procedures for liver cancer. The laparoscopic group and the open group were matched for age, sex, the size and location of the tumor, and the presence or absence of cirrhosis. Results  Thirty cases in the laparoscopic group were performed successfully while one case was converted to open surgery due to intraoperative hemorrhage. The length of hospital stay was 7.5 (5–15) days, which was significantly shorter than those in open group (p < 0.01). The mean operative time and blood loss in the laparoscopic group were 140.1 (60–380) min and 502.9 (50–2000) ml, respectively, which were lower than those in open group but without significant difference. There were no operative complications and no deaths in the laparoscopic group. The mean and median survival times of laparoscopic group were 59.3 and 70 months, compared with 49.4 and 60 months in the open group, respectively. The 1-, 3-, 5-year survival rates in the laparoscopic group were, respectively, 96.55%, 60.47%, and 50.40%, and 96.77%, 68.36%, and 50.64% in the open group. By log-rank test, these two survival curves were not significantly different (p = 0.8535). Conclusion  This study shows that laparoscopic hepatectomy for liver malignancy in selected patients is a safe, effective, and oncologically efficient procedure with better short-term results and similar survival outcomes to open hepatectomy for liver malignancy after midterm follow-up.     

Laparoscopic versus open ventral hernia mesh repair: a prospective study

Background An incisional hernia develops in 3% to 13% of laparotomy incisions, with primary suture repair of ventral hernias yielding unsatisfactory results. The introduction of a prosthetic mesh to ensure abdominal wall strength without tension has decreased the recurrence rate, but open repair requires significant soft tissue dissection in tissues that are already of poor quality as well as flap creation, increasing complication rates and affecting the recurrence rate. A minimally invasive approach was applied to the repair pf ventral hernias, with the expectation of earlier recovery, fewer postoperative complications, and decreased recurrence rates. This prospective study was performed to objectively analyze and compare the outcomes after open and laparoscopic ventral hernia repair. Methods The outcomes for 50 unselected patients who underwent laparoscopic ventral hernia repair were compared with those for 50 consecutive unselected patients who underwent open repair. The open surgical operations were performed by the Rives and Stoppa technique using prosthetic mesh, whereas the laparoscopic repairs were performed using the intraperitoneal onlay mesh (IPOM) repair technique in all cases. Results The study group consisted of 100 patients (82 women and 18 men) with a mean age of 55.25 years (range, 30–83 years). The patients in the two groups were comparable at baseline in terms of sex, presenting complaints, and comorbid conditions. The patients in laparoscopic group had larger defects (93.96 vs 55.88 cm²; p = 0.0023). The mean follow-up time was 20.8 months (95% confidence interval [CI], 18.5640–23.0227 months). The mean surgery durations were 90.6 min for the laparoscopic repair and 93.3 min for the open repair (p = 0.769, nonsignificant difference). The mean postoperative stay was shorter for the laparoscopic group than for the open hernia group (2.7 vs 4.7 days; p = 0.044). The pain scores were similar in the two groups at 24 and 48 h, but significantly less at 72 h in the laparoscopic group (mean visual analog scale score, 2.9412 vs 4.1702; p = 0.001). There were fewer complications (24%) and recurrences (2%) among the patients who underwent laparoscopic repair than among those who had open repair (30% and 10%, respectively). Conclusions The findings demonstrate that laparoscopic ventral hernia repair in our experience was safe and resulted in shorter operative time, fewer complications, shorter hospital stays, and less recurrence. Hence, it should be considered as the procedure of choice for ventral hernia repair.     

Incidence of Incisional Hernia Repair After Laparoscopic Compared to Open Resection of Colonic Cancer: A Nationwide Analysis of 17,717 Patients

Background

It remains unknown whether laparoscopic compared to open surgery translates into fewer incisional hernia repairs (IHR). The objectives of the current study were to compare the long-term incidence of IHR and the size of repaired hernias between patients subjected to laparoscopic or open resection of colonic cancer.

Methods

This was a nationwide cohort study comprised of patients undergoing resection for colonic cancer between January 2007 and March 2016 according to the Danish Colorectal Cancer Group database. Patients who subsequently underwent IHR were identified in the Danish Ventral Hernia Database, from which information about the priority of the hernia repair and the size of the fascial defect was retrieved.

Results

The study included 17,717 patients, of whom 482 (2.7%) underwent subsequent IHR during a median follow-up of 4.7 (interquartile range 2.8–6.9) years. There was no significant difference in the 5-year cumulative incidence of hernia repair after laparoscopic compared to open colonic resection (3.9%, CI 3.3–4.4% vs 4.1%, CI 3.5–4.6%). After adjustment for confounders, laparoscopic approach was associated with an increased rate of emergency IHR (HR 2.37, 95% CI 1.03–5.46, P = 0.042) as opposed to elective IHR (HR 0.91, 95% CI 0.73–1.14, P = 0.442). Laparoscopic surgery was significantly associated with a decreased fascial defect area compared to open surgery (mean difference −16.0 cm², 95% CI −29.4 to −2.5, P = 0.020).

Conclusions

There was no difference in the incidence of IHR after open compared to laparoscopic resection. Compared to the open approach, laparoscopic resection increased the rate of subsequent emergency IHR, suggesting that a more aggressive therapeutic approach may be warranted in this patient group upon diagnosis of an incisional hernia.

     

Laparoscopic vs open inguinal hernia repair

Background: The role of laparoscopic inguinal hernia repair is controversial. The aim of this study was to find out whether it is justified to switch from the predominantly modified Bassini repair which the authors had been using to laparoscopic repair. Methods: Randomized controlled trial in 120 eligible patients admitted for elective hernia repair in a university hospital. Results: Sixty patients underwent laparoscopic transabdominal preperitoneal mesh repair; the other 60 patients had an open repair, mostly with the modified Bassini technique. Operative time for laparoscopic repair was significantly longer, mean (s.d.) 95 (28) min vs 67 (27) min (p < 0.001). The mean analogue pain score during the first 24 h after surgery was 36.2 (20.2) in the laparoscopic group and 49.3 (24.9) in the open group (p= 0.006). The requirement for narcotic injections and postoperative disability in walking 10 m and getting out of bed were also significantly less following laparoscopic repair. The postoperative hospital stay was not significantly different, mean 2.6 (1.2) days for laparoscopic repair and 3.0 (1.5) days for open repair (p= 0.1). Patients were able to perform light activities without pain or discomfort sooner after laparoscopic repair, median interquartile range 8 (5–14) days vs 14 (8–19) days (p= 0.013). Patients also resumed heavy activities sooner, but not significantly, after laparoscopic repair, median 28 (17–60) days vs 35 (20–56) days (p= 0.25). The return to work was not significantly different, median 14 (8–25) days after laparoscopic repair and 15 (11–21) days after open repair (p= 0.14). After a mean follow-up of 32 months one patient developed a recurrent hernia 3 months after a laparoscopic repair. Laparoscopic repair was more costly than open repair by approximately $400. Conclusions. Laparoscopic inguinal hernia repair was associated with less early postoperative pain and disability and earlier return to full activities than open repair, but there were no benefits regarding postoperative hospital stay and return to work; laparoscopic repair was also more costly.

Staged laparoscopic adjuvant intraperitoneal chemohyperthermia after complete resection for locally advanced colorectal or gastric cancer: a preliminary experience

Background  Cytoreductive surgery followed by intraperitoneal chemohyperthermia (IPCH) is a promising treatment for patients with peritoneal carcinomatosis, a disease with dismal prognosis. Methods  We describe our preliminary experience with staged adjuvant laparoscopic IPCH after complete resection in patients with locally or regionally advanced colorectal or gastric cancer. Results  Twenty-one patients underwent resection for colorectal (N = 16) or gastric cancer (N = 5) followed by staged laparoscopic IPCH. No conversion to laparotomy was required. No major operative incident occurred. Mean duration of hospital stay was 12 days (range 9–23 days). No mortality occurred in the 30-day postoperative period. Four patients developed major complications (19%). One patient (5%) was reoperated. Mean follow-up period was 15.5 months (range 9–29 months). Three patients died, including two of cancer-related causes. No patient developed peritoneal carcinomatosis during the follow-up period. Conclusion  Staged laparoscopic adjuvant IPCH after open or laparoscopic resection in selected patients with colorectal or gastric cancer is feasible and reasonably safe. However, additional data are required to determine the effect on long-term survival.     

Laparoscopic vs open colectomy for sigmoid diverticulitis

Background: The aim of this prospective comparative study was to assess the outcome of laparoscopic and open colectomy for sigmoid diverticulitis in patients aged ≥75 years. Methods: From January 1993 to December 1998, all patients 75 years of age and older undergoing an elective colectomy for sigmoid diverticulitis were included in the study. The patients were divided into the following two groups: group 1 (n= 22) consisted of patients who underwent a laparoscopic procedure; group 2 (n= 24) consisted of patients who underwent an open procedure. Results: In group 1, there were 12 women and 10 men with a mean age of 77.2 years (range, 75–82); in group 2, there were 14 women and 10 men with a mean age of 78 years (range, 76–84) (p= 0.37). There was no difference between the groups in ASA classification. The operative time was shorter in group 2 (136 vs 234 mins). The postoperative period during which parenteral analgesics were required (5.4 vs 8.2 days, p= 0.001), postoperative morbidity (18% vs 50%, p= 0.02), postoperative length of hospital stay (13.1 vs 20.2 days, p= 0.003), and the inpatient rehabilitation (6 vs 15 patients, p= 0.01) were significantly shorter for group 1 than for group 2. There were no perioperative deaths. The conversion rate was 9% in group 1. Conclusion: The data from the present study suggest that laparoscopic colectomy for sigmoid diverticulitis can be applied safely to older patients with fewer complication, less pain, shorter hospital stay, and a more rapid return to preoperative activity levels than that seen with open colorectal resection.

Multidimensional analysis of the learning curve for laparoscopic colorectal surgery: lessons from 1,000 cases of laparoscopic colorectal surgery

Purpose  We consider quality of surgery throughout the learning curve and attempt to determine the learning curve for competency in performing laparoscopic colorectal surgery. Methods  The study included 1,014 patients who underwent laparoscopic colorectal resection between June 1996 and December 2007. We categorized patients into nine periods according to number of cases performed. Results  Operative time continuously decreased for right hemicolectomy (216 versus 150 min) and anterior resection (214.8 versus 147.7 min), whereas for low anterior resection it did not change over many periods and then significantly decreased after the ninth period (221.3 versus 176.4 min). The proportion of patients who had undergone previous abdominal surgery increased after the second period. Anastomotic leakage rate was 6–9% for the first 200 cases, and then decreased to less than 2%. More than 10% of operations were converted to open surgery during the first period, after which this rate significantly decreased to 2%. Number of harvested lymph nodes stabilized to 35–40 for right hemicolectomy after 200 cases, whereas for anterior and low anterior resection it was consistently 15–20 after the initial 20 cases. Overall, disease recurrence rate was 16–25%. For rectal cancer, local recurrence rate was highest (12%) in the fourth period and decreased thereafter to about 3%. Conclusion  Postoperative complications and local recurrence rate increased even after accumulation of experience because of expansion of indications for laparoscopic procedures.     

Critical evaluation of a novel DualMesh repair for large hiatal hernias

Background  The use of mesh for laparoscopic repair of large hiatal hernias may reduce recurrence rates in comparison to primary suture repair. However, there is a potential risk of mesh-related oesophageal complications due to prosthesis erosion. The aim of this study was to critically evaluate a novel mesh (DualMesh) repair of hiatal hernias with particular reference to intraluminal erosion. Method  Medical records of 19 patients who underwent laparoscopic hiatal hernia repair with DualMesh reinforcement of the crural closure were reviewed from a prospectively collected database. Quality of life and symptom analysis was performed using quality of life in reflux and dyspepsia (QOLRAD) questionnaires pre- and postoperatively after 6 weeks, 6 months, 1 year and 2 years. Barium studies were performed on patients pre-operatively and two years postoperatively to assess hernia recurrence. After 2 years, oesophagogastric endoscopy was performed to assess signs of erosion. Results  Mean patient age was 70.5 years (range 49–85 years). Two years after hiatal hernia repair, there was significant improvement in quality-of-life scores (QOLRAD: p < 0.001). Follow-up barium studies performed at 31.3 months (range 29–40 months) after surgery showed moderate recurrent hernias (>4 cm) in 1/14 patients (7%). Endoscopies performed at 34.4 months (range 28–41 months) after surgery did not show any signs of prosthetic erosion. Conclusion  Laparoscopic reinforcement of primary hiatal closure with DualMesh leads to a durable repair in patients with large hiatal hernias. Long-term endoscopic follow-up did not show any signs of mesh erosion after prosthetic reinforcement of the crural repair.     

Adhesions are Common and Costly after Open Pouch Surgery

Purpose  Open ileal pouch surgery leads to high rates of adhesive small-bowel obstruction (SBO). A laparoscopic approach may reduce these complications. We aimed to review the incidence of adhesive SBO-related complications after open pouch surgery and to model the potential financial impact of a laparoscopic approach purely as an adhesion prevention strategy. Materials and Methods  We reviewed cases of open ileal pouch patients kept on a database and examined annually. Case notes were studied for episodes of adhesive SBO requiring admission or reoperation. Similar parameters were studied in a small series undergoing laparoscopic pouch surgery. The financial burden of the open access complications was estimated and potential financial impact of a laparoscopic approach modeled. Results  Two hundred seventy-six patients were followed up after open surgery (median, 6.3; range, 0.2–20.1 years). There were 76 (28%) readmissions (median length of stay, 7.4 days) in 53 patients (19%) and 28 (10%) reoperations (43% within 1 year). Laparoscopic patients required less adhesiolysis at second-stage surgery (0% vs 36%, p < 0.0001) and had less SBO episodes within 12 months of surgery (0% vs 14%, p < 0.0001) than open patients. Modeling a laparoscopic approach cost $1,450 and saved $3,282, thus netting $1,832 per pouch constructed. Conclusion  Open ileal pouch surgery results in significant cumulative long-term access-related complications, particularly adhesions. These impose a large medical burden on patients and financial burden on health-care systems, all of which may be recouped by a laparoscopic approach, despite higher theater costs.     

Laparoscopic ventral hernia repair: a systematic review

Background  Laparoscopic ventral hernia repair may be an alternative to open mesh repair as it avoids a large abdominal incision, and thus potentially reduces pain and hospital stay. This review aimed to assess the safety and efficacy of laparoscopic ventral hernia repair in comparison with open ventral hernia repair. Method  A systematic review was conducted, with comprehensive searches identifying six randomised controlled trials (RCTs) and eight nonrandomised comparative studies. Results  The laparoscopic approach may have a lower recurrence rate than the open approach and required a shorter hospital stay. Five RCTs (Barbaros et al., Hernia 11:51–56, 2007; Misra et al., Surg Endosc 20:1839–1845, 2006; Navarra et al., Surg Laparosc Endosc Percutan Tech 17:86–90, 2007; Moreno-Egea et al., Arch Surg 137:266–1268, 2002; Carbajo et al., Surg Endosc 13:250–252, 1999) reported no conversion (0%) to open surgery, and four nonrandomised studies reported conversions to open surgery ranging from 0% to 14%. Open approach complications generally were wound related, whereas the laparoscopic approach reported both wound- and procedure-related complications and these appeared to be less frequently reported. Conclusion  Based on current evidence, the relative safety and efficacy of the laparoscopic approach in comparison with the open approach remains uncertain. The laparoscopic approach may be more suitable for straightforward hernias, with open repair reserved for the more complex hernias. Laparoscopic ventral hernia repair appears to be an acceptable alternative that can be offered by surgeons proficient in advanced laparoscopic techniques.     

Impact of laparoscopic surgery on bladder and sexual function after total mesorectal excision for rectal cancer

Background  Bladder and sexual dysfunction are well-documented complications of rectal cancer surgery. This study aimed to determine whether laparoscopy can improve the outcome of these dysfunctions or not. Methods  The study included 63 of the 116 patients who underwent surgery for rectal cancer between 2002 and 2006. Bladder and male sexual function were studied by means of a questionnaire on the basis of the International Prostatic Symptom Score (IPSS) and International Index of Erectile Function (IIEF). In addition, bladder function was determined by means of postvoid residual urine measurement and uroflowmetry. Postoperative functions were compared with the preoperative data to detect subjective functional deterioration. Outcomes were compared between patients who underwent open (group 1, n = 29) and laparoscopic (group 2, n = 34) total mesorectal excision. Results  Only minor disturbances of bladder function were reported for one patient (3%) in group 1 and three patients (9%) in group 2 (p > 0.05). Impotency after surgery was experienced by 6 of 17 preoperatively sexually active males (29%) in group 1 and 1 of 18 males (5%) in group 2 (p = 0.04). Similarly, 5 of 10 women (50 %) in group 1 and 1 of 14 women (7%) in group 2 felt that their overall level of sexual function had decreased as a result of surgery (p = 0.03). Conclusions  Open rectal cancer resection is associated with a higher rate of sexual dysfunction, but not bladder dysfunction, compared with laparoscopic surgery. Laparoscopic rectal cancer surgery offers a significant advantage with regard to preservation of postoperative sexual function and constitutes a true advance in rectal cancer surgery compared with the open technique. The proposed advantages can be attributed to improvement in visibility by the magnification feature of laparoscopic surgery.
