Bariatric Surgery Waiting Lists in Spain.

Bariatric surgery is one of the most common general surgery procedures in countries that, like Spain, have public healthcare systems, but is also one of the procedures for which patients have to wait the longest. The Spanish Society of Obesity Surgery (SECO) conducted a survey to estimate the situation of bariatric surgery waiting lists in Spain's public hospitals and to gather information on a number of related aspects. METHODS: An online survey was sent to the members of the SECO. The survey received 137 visits, all via the click-through link provided, from 52 health centers (47 public and 5 private). The data collected were included in a database and later analyzed using the SPSS18.0 statistical software package. RESULTS: A total of 4724 patients were on bariatric surgery waiting lists (BWLs), at an average of 100 per public hospital. Sixty-eight percent had been waiting for more than 6 months. The mean delay per patient was 397 days, and the longest wait was 1661 days. A further 46.2% of respondents were able to recall cases of patients who in the past 5 years had suffered cardiovascular events with sequelae while awaiting surgery, and 21.2% recalled at least one fatal cardiovascular event in that time. CONCLUSION: Our data revealed an unacceptably long wait for obesity surgery. Notwithstanding the limitations and potential biases of our research, the long wait for surgery in our context inevitably has serious consequences for a potentially significant number of patients.

Usefulness of Clinical Signs and Diagnostic Tests for Suspected Leaks in Bariatric Surgery.

BACKGROUND: The early diagnosis of leakage poses a challenge to bariatric surgeons, who need to suspect and treat it promptly. The aim of this study is to determine the value of clinical signs and complementary tests in its detection. METHODS: Between January 2007 and 2012, 200 patients underwent surgery for pathological obesity. Perioperative variables were collected prospectively, and univariate and multivariate analyses were conducted to study the factors related to leak occurrence and the predictive value of the tests performed. RESULTS: The study includes 172 proximal gastric bypasses and 28 sleeve gastrectomies. Nine patients (4.5 %) had leaks in the immediate postoperative period. Multivariate analyses found that age over 48 years and preoperative BMI > 48 kg/m(2) were the patient-related variables associated with a higher risk of leakage. The clinical variables significantly related to postoperative leaks were heart rate over 100 bpm, leukocytes over 15,000/mm(3) and systolic arterial pressure below 100 mmHg. In patients with a clinical suspicion of leakage (n = 19), 7.7 % of abdominal CT scans returned false negatives, versus 28.6 % for oral methylene blue and 22.2 % for upper gastrointestinal (UGI) Gastrografin swallow [Corrected]. CONCLUSIONS: Bariatric surgery proved to be a safe technique at our medical centre. Patient-related variables associated with a higher risk of leakage were age and BMI. Early clinical signs of leakage were tachycardia, leukocytosis and hypotension. The most reliable diagnostic test was the abdominal CT scan.

Polymorphisms of interleukin-6 and tumor necrosis factor gene promoters and cardiorespiratory function following liver transplantation: a preliminary study.

INTRODUCTION: The interindividual variability in cardiorespiratory function during liver transplantation (OLT) has been attributed to various factors, including polymorphisms in immunity genes known to affect the circulation levels of cytokines. AIM: To evaluate polymorphisms of genes encoding for interleukin-6 (IL6) and tumor necrosis factor (TNF) in association with cardiorespiratory function in OLT. DESIGN: Prospective observational study. PATIENTS AND METHODS: We studied 62 consecutive patients who had OLT performed in our hospital between 2004 and 2005. Polymorphisms at positions -308 and -409 of TNF gene, as well as those at -174 and -574 of IL6 gene were determined in all patients by means of PCR-RFLPs. Associations were carried out using chi-square tests and analysis of variance. A bilateral P < .05 was accepted as significant. RESULTS: No statistically significant associations were observed. CONCLUSIONS: A relationship between the polymorphisms studied and respiratory function in OLT was lacking. These results must be interpreted with caution due to the limited sample size.

Obstruction of the bypassed stomach treated with percutaneous drainage: an alternative treatment for selected cases.

Biliopancreatic limb obstruction in Roux-en-Y gastric bypass is an infrequent complication that should be recognized early to avoid the risk of peritonitis and death. In this manuscript, we report a case of acute gastric remnant dilatation secondary to intraabdominal hematoma provoked by trocar injury that was compressing the second portion of duodenum lumen. To treat this problem, we decided on a less invasive treatment consisting of percutaneous decompression of the stomach. The procedure was performed using sonographic guidance with local anesthesia, thus, avoiding a new surgical procedure. In this selected case, percutaneous radiological catheter placement provided an effective decompression of the excluded gastric remnant until spontaneous resolution of the obstruction.

Effectiveness of colorectal laparoscopic surgery on patients at high anesthetic risk: an intervention cohort study.

AIMS: The aim of the study was to assess the effectiveness of laparoscopic colorectal surgery in patients at high preoperative anesthetic risk because of associated pathologies. MATERIALS AND METHODS: From January 2003 until January 2005, 116 patients were systematically assigned at a ratio of 1:1 to one of two groups: laparoscopy surgery (n=59, of which 31 were American Society of Anesthesiologists score [ASA] I-II [L1] and 28 ASA III-IV [L2]) or open surgery (n=57, of which 30 were ASA I-II [O1] and 27 ASA III-IV [O2]). Data on patient demographics and clinical and anesthetic variables were collected prospectively. Informed consent was obtained from the patients, and approval was obtained from the designated review board of the institution involved. RESULTS: The number of minor anesthetic complications during surgery was higher in L2 patients. No differences were observed in blood gas parameters studied during surgery (pCO(2), pH, and pO(2)/FiO(2)). Transfusion rates in the laparoscopy group at greater anesthetic risk (L2) were lower than those of the high-risk conventional surgery group (O2; 21.4 vs 63%, P<0.02). Duration of stay in the surgical recovery room and the inpatient ward were also shorter in the L2 group than in the O2 group (8.7+/-4.5 vs 12.2+/-6 days, P=0.02). There was no difference in perioperative clinical variables between laparoscopy groups (L1, L2). CONCLUSION: Postoperative recovery of ASA III-IV patients is better after laparoscopic surgery for colorectal cancer, at the expense of a higher rate of minor anesthetic occurrences during surgery.

Carcinoid syndrome misdiagnosed as a malabsorptive syndrome after biliopancreatic diversion.

A case is reported of a woman who developed untreatable diarrhea after a prior biliopancreatic diversion (BPD), attributed to the malabsorptive component. Abdominal ultrasound incidentally found focal liver lesions. On fine needle aspiration biopsy, atypia was found, and these hepatic lesions were resected with free margins. The specimen showed liver metastases of an aggressive malignant neuroendocrine neoplasm. The primary site was subsequently identified to be in the pancreas. The physician and surgeon must realize that non-related diseases can develop after bariatric surgery, as in the general population.

Restorative proctocolectomy with an ileoanal pouch: the role of laparoscopy.

OBJECTIVES: The Aim of this retrospective study was to evaluate early experience with laparoscopic restorative proctocolectomy by analyzing the perioperative results of surgical treatment. PATIENTS AND METHODS: Seven major surgeries were performed in six patients with familial adenomatous polyposis and ulcerative colitis. All procedures were performed under laparoscopy at our third-level hospital from June 2003 to October 2004. RESULTS: Mean surgical time was 287.5 +/- 80.7 min, and median blood loss was 300 +/- 249.0 cc. There were no conversions; return of peristalsis began at 32 +/- 12.4 h; average time to first oral intake was 64.0 +/- 32.8 h, and mean duration of hospital stay was 9.3 +/- 1.2 days. There was one case of perineal sepsis due to ileal pouch-anal anastomotic leakage, which was successfully treated with oral intake restriction, parenteral nutrition, and intra-rectal drainage. The most common postoperative complication was postoperative ileus. CONCLUSIONS: We believe that the laparoscopic approach to restorative proctocolectomy may be considerably improved in our center. Particular aspects for improvement include efforts to achieve lower operating and hospitalization times to equate our results with those reported by multicenter studies for laparoscopic colon cancer surgery. In our opinion, learning and further training opportunities should be encouraged to improve surgeon experience in the field of laparoscopy, preferably at centers specializing in restorative proctocolectomy.

An unusual case of hemoperitoneum owing to acute splenic torsion in a child with immunoglobulin deficiency.

Wandering spleen is an uncommon clinical entity, which rarely affects children and adolescents. It is usually described in adults, being most common in the multiparous women of childbearing age. A case of a 14-year-old girl with a past history of splenomegaly and immunoglobulin A (IgA) deficiency, who presented with a sudden onset of abdominal pain, is presented. Diagnosis of hemoperitoneum secondary to torsion of a wandering spleen was made by computed tomography scan and Doppler ultrasound. Laparoscopy revealed hemoperitoneum owing to a ruptured and infarcted spleen. Laparotomy was undertaken and open splenectomy was successfully performed. The patient was discharged after an uneventful postoperative course that was not punctuated by any major complication. Management of this rare surgical emergency is discussed. Based on the details of this case, the authors hypothesize that IgA deficiency causes splenomegaly, which in turn predisposes to ligamentous laxity and splenic torsion.

Ileoileal intussusception as initial manifestation of Crohn's disease.

Intussusception is usually considered a childhood condition, but it may also be present in adults, where it is more often associated with an underlying pathology. There is no agreement upon the correct treatment of adult intussusception, although surgical intervention is considered necessary. Resection without prior reduction has been the traditional treatment of choice due to the significant risk for malignancy found in most series. We describe an unusual case of intestinal necrosis secondary to ileoileal intussusception caused by Crohn's disease. A long intestinal resection was necessary and the patient was discharged without major complications. Based on the details of this case, the authors emphasize the potential importance of considering individualized treatment of adult intussusception. The practical benefit for reduction of viable bowel in Crohn's patients is the preservation of bowel length.

Laparoscopic repair of incarcerated low spigelian hernia with transperitoneal PTFE DualMesh.

There are different types of hernias that can develop at certain sites in the abdominal wall. Spigelian hernia (SH) is a protrusion of abdominal contents through a defect in the spigelian aponeurosis, in proximity to the external margin of the rectus muscle. Usually, abdominal wall hernia sac contains the omentum but may also contain small intestine that might become trapped in the hernia. When ischemia of herniated contents is suspected, urgent surgical treatment is advocated. Elective laparoscopic repair of SH is still under discussion. However, a recent randomized study comparing open and laparoscopic repair as elective treatment suggested that extraperitoneal laparoscopic repair is the technique that offers best results for the patients. Recent development of new biologic materials and technologies in laparoscopy has led to improved results. We report the successful repair of incarcerated low SH that was successfully managed by urgent laparoscopic intraperitoneal onlay polytetrafluoroethylene mesh hernioplasty.
