Synthetic Versus Biological Mesh in Laparoscopic and Open Ventral Hernia Repair (LAPSIS): Results of a Multinational, Randomized, Controlled, and Double-blind Trial.

OBJECTIVE: The aim of this study was to investigate the approach (open or laparoscopic) and mesh type (synthetic or biological) in ventral hernias in a clean setting.Summary of Background Data: The level of evidence on the optimal surgical approach and type of mesh in ventral hernia repair is still low. METHODS: Patients with a ventral abdominal hernia (diameter 4-10 cm) were included in this double-blind randomized controlled trial across 17 hospitals in 10 European countries. According to a 2 × 2-factorial design, patients were allocated to 4 arms (open retromuscular or laparoscopic intraperitoneal, with synthetic or Surgisis Gold biological mesh). Patients and outcome assessors were blinded to mesh type used. Major postoperative complication rate (hernia recurrence, mesh infection, or reoperation) within 3 years after surgery, was the primary endpoint in the intention-to-treat population. RESULTS: Between September 1st, 2005, and August 7th, 2009, 253 patients were randomized and 13 excluded. Six of 61 patients (9.8%) in the open synthetic mesh arm, 15 of 66 patients (22.7%) in the open biological mesh arm, 7 of 64 patients (10.9%) in the laparoscopic synthetic mesh arm and 17 of 62 patients (27.4%) in the laparoscopic biological mesh arm had a major complication. The use of biological mesh resulted in significantly more complications (P = 0.013), also after adjusting for hernia type, body mass index, and study site. The trial was prematurely stopped due to an unacceptable high recurrence rate in the biological mesh arms. CONCLUSIONS: The use of Surgisis Gold biological mesh is not recommended for noncomplex ventral hernia repair. TRIAL REGISTRATION: This trial was registered at controlled-trials.com (ISRCTN34532248).

Lower incidence of hepatic metastases of colorectal cancer in patients with chronic liver diseases: meta-analysis.

BACKGROUND/AIMS: The rarity of metastatic malignancy in injured liver has been noticed. This meta-analysis evaluates the difference in occurrence of metastatic colorectal cancer in healthy and chronically injured liver. METHODOLOGY: Literature search of occurrence of metastatic colorectal cancer in chronically injured liver opposed to healthy liver was conducted. Chronically injured/damaged liver included cirrhosis, steatosis or fatty liver and infection with Hepatitis virus B or C. RESULTS: A total of 7 retrospective studies between 1992 and 2010 matched the selection criteria with total of 4049 patients. Results suggest significantly lower incidence of colorectal metastasis in chronically injured liver (Pooled odds ratio = 0.260 (95% CI = 0.18 to 0.38); χ² (test odds ratio differs from 1) = 45.90 (df = 1); p <0.0001). CONCLUSIONS: Patients with chronic liver injury have significantly lower occurrence of hepatic metastasis of primary colorectal cancer than the patients with healthy liver.

The current evidence on stapled versus hand-sewn anastomoses in the digestive tract.

The innovation process and developments in technology have given surgeons new products which can improve their performance and benefit our patients. Before the era of laparoscopic surgery one of the most important applications in surgical practice was the introduction of staplers. In this article, the evidence supporting the decision whether to use a mechanical device (stapler) or to make a hand-sewn anastomosis is presented. A sytematic review of the literature was performed. The search included published meta-anaylses, randomized clinical trials and comparative studies. Key words for the initial search were: surgical anastomosis, stapler, hand-sewn. There was no language restriction. The reference lists from the selected articles were also checked by the author. Literature data on main outcomes concerning the application of one or the other surgical technique have been analysed. The literature search yielded published data on various procedures in digestive surgery. Most of the available high-quality evidence was for gastric and colorectal resections. Resection of the esophagus, use of staplers in emergency procedures and some initial reports on pancreatic surgery were also retrieved. The evidence from the literature shows that stapler anastomoses take less operative time and are more costly than hand-sewn anastomoses. Regarding the morbidity and leaks rate the staplers give equal or better results when compared with the hand-sewn technique. Nevertheless, proper handling of staplers and experience remain crucial issues if one wants to gain benefits when using these devices.

[Fast track surgery--enhanced multimodal rehabilitation after surgery]. / "Fast track" kirurgija--ubrzana multimodalna rehabilitacija kirurskih bolesnika.

Despite constant improvements in surgical technique and perioperative care which led to significant reductions in mortality and morbidity after general surgery, complication rates after major abdominal surgery still reach 15-40%. The main cause of postoperative complications (not linked to surgical technique itself) is the perioperative stress reaction potentiated by pain, inadequate perioperative fluid management, immobilisation and hypothermia. Multimodal rehabilitation of surgical patients represents the practical application of advances in surgery, anaesthesiology and postoperative rehabilitation with the aim of reducing perioperative stressors and facilitating an early return of the patient to his/her preoperative functional status. Besides discussing various aspects of multimodal rehabilitation, the authors present their own first experiences with its introduction into everyday clinical practice.

Improving comprehension of informed consent.

OBJECTIVE: To explore the way the doctor-patient communication process may be improved by adopting the patients' conversational style in the development of written materials for surgical patients. METHODS: Written information prepared by doctors, specialists in abdominal surgery, was tested for comprehension on patients undergoing cholecystectomy, using the standard Cloze test procedure. At the same time, the patients were asked to describe in their own words all they knew about their illness and the treatment. The collected 150 patient narratives were analyzed, and a typical narrative for each educational level was selected based on average SMOG score, word count and sentence length. The patient-worded information was then tested for comprehension on new patients, selected from primary health care, using the same Cloze procedure as with doctor-developed information. Patient profile of best lay communicators was defined using also sociodemographic characteristics, and reported information seeking and decision making preferences. RESULTS: Only 50% of patients completed Cloze test, of which over 40% showed poor comprehension. Analysis of transcribed narratives collected from 150 patients showed increasing complexity of style by educational level (average SMOG score 7, 8, and 9; sentence length 11, 13, and 15 words; for low, medium, and high educational level, respectively). Cloze tests based on typical narratives, and tested on primary care patients, indicated to the style best understood by all. Dominant characteristics of patients producing a narrative of similar style to the best-understood narrative were observed: medium educational level, women over 60, urban workers, interviewed after surgery, informed by specialist at ultrasound, knowledge about illness from 1 to 10 years, learned most about illness from lay people, those who wanted more information in both oral and written form, and preferred active role in decision making. CONCLUSION: Analysis of patient profiles with typical narratives that were best understood by other patients shows where to look for lay experts in doctor-patient communication. PRACTICE IMPLICATIONS: Obtained findings indicate to the importance of patient participation in developing informed consent information, and to the possible method for improving comprehension of educational patient materials in general.

Suture granuloma of the abdominal wall with intra-abdominal extension 12 years after open appendectomy.

Most complications after appendectomy occur within ten days; however, we report the unusual case of a suture granuloma 12 years after open appendectomy. The afebrile 75-year-old woman presented with a slightly painful palpable mass in the right lower abdomen. There was no nausea or vomiting and bowel movements were normal. She lost 10 kg during the 3 mo before presentation. The patient had undergone an appendectomy 12 years previously. Physical examination revealed a tender mass, 10 cm in diameter, under the appendectomy scar. The preoperative laboratory findings, tumor markers and plain abdominal radiographs were normal. Multi-slice computed tomography scanning showed an inhomogenous abdominal mass with minimal vascularization in the right lower abdomen 8.6 cm x 8 cm x 9 cm in size which communicated with the abdominal wall. The abdominal wall was thickened, weak and bulging. The abdominal wall mass did not communicate with the cecum or the ascending colon. Complete excision of the abdominal wall mass was performed via median laparotomy. Histopathological examination revealed a granuloma with a central abscess. This case report demonstrates that a preoperative diagnosis of abdominal wall mass after open appendectomy warrants the use of a wide spectrum of diagnostic modalities and consequently different treatment options.
