RESUMEN
BACKGROUND: The objective of this study was to determine the relationship between perioperative complications and the severity of obstructive sleep apnoea (OSA) in patients undergoing bariatric surgery who had undergone preoperative polysomnography (PSG). METHODS: The records of 797 patients, age >18 yr, who underwent bariatric operations (442 open and 355 laparoscopic procedures) at Mayo Clinic and were assessed before operation by PSG, were reviewed retrospectively. OSA was quantified using the apnoea-hypopnoea index (AHI) as none (≤ 4), mild (5-15), moderate (16-30), and severe (≥ 31). Pulmonary, surgical, and 'other' complications within the first 30 postoperative days were analysed according to OSA severity. Logistic regression was used to assess the multivariable association of OSA, age, sex, BMI, and surgical approach with postoperative complications. RESULTS: Most patients with OSA (93%) received perioperative positive airway pressure therapy, and all patients were closely monitored after operation with pulse oximetry on either regular nursing floors or in intensive or intermediate care units. At least one postoperative complication occurred in 259 patients (33%). In a multivariable model, the overall complication rate was increased with open procedures compared with laparoscopic. In addition, increased BMI and age were associated with increased likelihood of pulmonary and other complications. Complication rates were not associated with OSA severity. CONCLUSIONS: In obese patients evaluated before operation by PSG before bariatric surgery and managed accordingly, the severity of OSA, as assessed by the AHI, was not associated with the rate of perioperative complications. These results cannot determine whether unrecognized and untreated OSA increases risk.

Intestinal denervation contributes to enteric motor dysfunction after intestinal transplantation [small bowel transplantation (SBT)]. Our aim was to determine long-term effects of extrinsic denervation on functional non-adrenergic, non-cholinergic innervation with vasoactive intestinal polypeptide (VIP) and substance P. Contractile activity of jejunal longitudinal muscle from six age-matched, naïve control rats (NC) and eight rats 1 year after syngeneic SBT were studied in tissue chambers. Spontaneous contractile activity did not differ between groups. Exogenous VIP inhibited contractile activity dose-dependently in both groups, greater in NC than in SBT. The VIP antagonist ([D-p-Cl-Phe(6),Leu(17)]-VIP) and the nitric oxide synthase inhibitor l-N(G)-nitro arginine prevented inhibition by exogenous VIP and electrical field stimulation (EFS) in both groups. Exogenous substance P increased contractile activity dose-dependently, greater in NC than in SBT. The substance P antagonist ([D-Pro(2),D-Trp(7,9)]-substance P) inhibited effects of exogenous substance P and increased the EFS-induced inhibitory response. Immunohistofluorescence showed staining for tyrosine hydroxylase in the jejunoileum 1 year after SBT suggesting sympathetic reinnervation. In rat jejunal longitudinal muscle after chronic denervation, response to exogenous VIP and substance P is decreased, while endogenous release of both neurotransmitters is preserved. These alterations in excitatory and inhibitory pathways occur despite extrinsic reinnervation and might contribute to enteric motor dysfunction after SBT.

A mechanosensitive Na(+) current carried by Na(v)1.5 is present in human intestinal circular smooth muscle and contributes to regulation of intestinal motor function. Expression of this channel in different species is unknown. Our aim was to determine if Na(+) currents and message for the alpha subunit of the Na(+) channel (SCN5A) are found in circular smooth muscle cells of human, dog, pig, mouse and guinea pig jejunum. Currents were recorded using patch clamp techniques. Message for SCN5A was investigated using laser capture microdissection and reverse transcription polymerase chain reaction (RT-PCR). Na(+) currents were identified consistently in human and dog smooth muscle cells; however, Na(+) current was not found in pig (0/20) or guinea pig smooth muscle cells (0/21) and found only one mouse cell (1/21). SCN5A mRNA was found in circular muscle of human, dog, and mouse, but not in pig or guinea pig, and not in mouse longitudinal or mucosal layers. In summary, SCN5A message is expressed in, and Na(+) current recorded from, circular muscle layer of human and dog but not from pig and guinea pig. These data show that there are species differences in expression of the SCN5A-encoded Na(v)1.5 channel, suggesting species-specific differences in the electrophysiological response to mechanical and depolarizing stimuli.

RESUMEN
The understanding of peptic ulcer disease (PUD) etiology, and improvements in treatment during the last two decades, has dramatically decreased the once so frequently performed procedures for PUD and its complications. Benign gastric outlet obstruction may, however, still require operative intervention when non-operative treatment fails. Today, surgeons in training, and even practicing surgeons, may have limited operative experience with procedures required to alleviate an obstructed pylorus. Our aim of this paper is to review the techniques (the Heineke-Mikulicz and Finney pyloroplasties, and modifications) and indications for pyloroplasty in the modern surgical era.

INTRODUCTION: Secondary prevascular hernias occurring anterior to the iliofemoral vessels and involving the lower abdominal wall are rare. These hernias can be difficult to repair because of loss of the inguinal ligament and the musculofascial elements of the inguinal region. MATERIALS AND METHODS: We describe a new technique of repair using an intraperitoneal sling of prosthetic material. The sling is sewn posteriorly to the anterior surface of the sacrum, and is then draped caudally to be sewn to the pubis and Cooper's ligaments before being reflected anterior to be sewn to the posterior surface of the anterior abdominal wall. This sling "patches" the hernia defect as a form of intraperitoneal sublay. CONCLUSIONS: We describe three such patients with satisfactory results at follow-ups of 8-16 months. Potential problems and considerations are discussed.

PURPOSE: We reviewed retrospectively all patients undergoing abdominal wall reconstruction using porcine acellular dermal matrix (PADM) from 2004 to 2008 with follow-up assessment in 2012. Technique, short-term (infection, seroma, wound dehiscence), and long-term (mesh infection, recurrence) complications, and hernia recurrences were evaluated by physician examination ≥5 years postoperatively. RESULTS: 56 patients at high risk for infection had elective operation; nine had non-elective operation for complications of prior incisional hernia/hernia repair. Operations were clean, clean-contaminated, contaminated, or grossly infected in 49, 32, 12, and 6%, respectively. Techniques of repair included 10 onlay (six reinforced primary closures, four bridging patches), 47 sublay (20 reinforced primary closures, 27 bridging patches), six inlay, and two sandwich (sublay and onlay). Early complications (≤30 days postoperatively) occurred in 19 of the 65 patients (29%), including two prosthetic dehiscences from fascial attachment, 13 wound infections, and 4 seromas. After a mean follow-up of ≥5 years in 59 of 65 patients, physician-reported incidences of infection requiring removal of mesh or hernia recurrence were 25 and 66%, respectively. Hernia recurrence occurred in 12 of 26 (46%) patients with a reinforced repair and 27 of 33 (82%) with patched repairs. Mesh infection occurred in 7 of 24 patients with sublay patch and in 4 of 19 sublay reinforcement. The greatest recurrence rate was in contaminated (71%) and grossly infected wounds (100%), while recurrence rate was 63% in clean and 63% in clean-contaminated wounds. CONCLUSIONS: At ≥5 years of follow-up, use of PADM as a bioprosthesis in ventral hernia in high-risk patients is unreliable as a definitive repair in the majority of patients, but may provide satisfactory outcomes in some patients.

Paget's disease of the breast is a rare disorder of the nipple-areola complex that is often associated with an underlying in situ or invasive carcinoma. A change in sensation of the nipple-areola, such as itching and burning, is a common presenting symptom. Objectively, eczematoid changes of the nipple-areola complex are common. The later stages of Paget's disease of the breast are characterized by ulceration and destruction of the nipple-areola complex. Eczematoid changes of the nipple-areola complex and persisting soreness or itching, without obvious reason, is a suspicious symptom for Paget's disease of the breast and calls for thorough evaluation, including mammography. Exfoliative cytology with demonstration of Paget's cells may be useful, but a negative finding does not exclude Paget's disease of the breast. Surgical biopsy is the diagnostic standard and therefore the diagnosis should always be confirmed by open (surgical) biopsy. The histogenesis of Paget's disease of the breast continues to be debated. The epidermotropic theory holds that Paget's cells are ductal carcinoma cells that have migrated from the underlying breast parenchyma to the nipple epidermis. According to the in situ transformation theory, the Paget's cells arise as malignant cells in the nipple epidermis independent from any other pathologic process within the breast parenchyma. This theory has been proposed to explain those cases in which there is no underlying mammary carcinoma or when there is a carcinoma remote from the nipple-areola complex. Each of these theories is plausible; however, treatment approaches differ markedly depending on the theory of histogenesis. Mastectomy has been considered the standard of care in the management of patients with Paget's disease of the breast. Nowadays, however, some patients with Paget's disease of the breast are candidates for breast-conserving therapy. Patients must be selected carefully on an individual basis. Until there is a better understanding of the relationship of Paget's disease of the breast to the underlying cancer the surgeon should understand the natural history and behaviour of this lesion and be aware of both the risks of under- and over-treating patients with Paget's disease of the breast.

This study was undertaken to determine the effects of somatostatin 201-995 (SMS) on the maintenance dose of intravenous cyclosporine and on graft blood flow, exocrine secretion, and rejection after porcine pancreaticoduodenal allotransplantation (PDA). For seven days, 12 pigs (6 control, 6 SMS-treated) were studied to determine the effects of SMS on serum CsA concentrations. Twenty-six pigs (14 control, 12 SMS) with streptozocin-induced diabetes underwent PDA. Blood flow was measured through graft celiac and superior mesenteric arteries 15 and 60 min after reperfusion. SMS (75 micrograms s.c.) was given after the 15-min blood-flow measurement in the SMS group. Sixteen pigs (8 control, 8 SMS) were followed postoperatively with daily measurements of serum glucose and amylase concentrations, and urine amylase and trypsin activities. All pigs were immunosuppressed with azathioprine, prednisone, and i.v. CsA. SMS pigs also received SMS (75 micrograms s.c.) every 8 hr. SMS had no effect on maintenance dose of CsA or on serum amylase, urine amylase, or urine trypsin activities. Mean days to rejection were also not affected. Intraoperative graft blood flow was significantly decreased by SMS, but incidence of graft thrombosis was unchanged. These results suggest that in the porcine PDA model, SMS does not appear to inhibit exocrine secretion and potentially may adversely affect the early course of PDA by decreasing graft blood flow.

We evaluated the use of a needle catheter jejunostomy in 83 consecutive patients who underwent complicated abdominal operations. We used the needle catheter jejunostomy to deliver immediate postoperative nutrition (mean, 1,700 kcal/day) in 66 patients for a range of 4 to 80 days. In addition, the needle catheter jejunostomy was used to provide all maintenance fluid and electrolyte needs and to administer almost all required medications. No serious complications were related to use of the needle catheter jejunostomy, although easily controlled diarrhea occurred in 16 patients (19%). We concluded that the needle catheter jejunostomy is a safe and cost-effective means of delivering postoperative nutrition, fluid and electrolytes, and most medications in selected patients undergoing high-risk abdominal operations.

Herein we describe two patients with medically refractory, severe reflux esophagitis after vertical banded gastroplasty for morbid obesity. Neither patient had symptoms of reflux preoperatively. Both patients underwent conversion to a vertical Roux-en-Y gastric bypass, an operation that prevents acid and peptic reflux and maintains a weight-reducing anatomy. Symptoms of gastroesophageal reflux are common (they occur in approximately 38% of patients) after vertical banded gastroplasty has been performed. Patients with unusually severe reflux may require operative management.

A 70-year-old man had an unusual type of supravesical small bowel hernia associated with herniation of the bladder through a traumatic diastasis of the pubic symphysis. The diastasis was closed with prosthetic mesh through a preperitoneal approach. In patients in whom a scrotal hernia develops after a previous pelvic fracture, especially those with evidence of a pubic diastasis, an unusual type of hernia should be suspected. A preperitoneal surgical approach best reveals the anatomy and allows appropriate repair. The best procedure for prevention of such hernias is primary reduction of any substantial pubic diastasis, but operative intervention is not indicated in all patients.

The increasing prevalence and far-reaching medical, social, and economical implications of obesity have made it a national health-care crisis in the United States. About one in every three persons is at least 20% above "ideal" body weight, and approximately 5% have direct weight-related serious health problems (morbid obesity), including hypertension, hyperlipidemia, coronary artery disease, adult-onset diabetes mellitus, degenerative osteoarthropathy, and obstructive sleep apnea. Morbidly obese patients have an estimated 6- to 12-fold increase in mortality. In addition, they have a substantially diminished quality of life, not only physically but also psychosocially due to overt and occult prejudice. Weight reduction must be aggressively pursued in these patients. Medically supervised weight-control programs have been ineffective because patients cannot maintain pronounced long-term weight loss. In contrast, current operative methods have been proved to be effective in helping patients achieve and maintain permanent weight reduction. Several operations have been designed and assessed; with these procedures, weight loss is achieved by inducing malabsorption, maldigestion, early satiety, or a combination of these outcomes. Although these operations have associated side effects and limitations, the expected benefits outweigh the risks. For optimal results, patients must be carefully selected and treated by a multidisciplinary group.

OBJECTIVE: To assess our initial experience with a variety of laparoscopic procedures that can be performed by general surgeons with the basic skills used for laparoscopic cholecystectomy and without advanced laparoscopic expertise. MATERIAL AND METHODS: We retrospectively reviewed a 36-month experience (1991 through 1994) at our institution with a consecutive series of patients who underwent basic laparoscopic surgical procedures but specifically excluding cholecystectomy, appendectomy, herniorrhaphy, and colectomy. RESULTS: Procedures performed laparoscopically included gastrostomy, jejunostomy, small bowel resection, intra-abdominal and retroperitoneal biopsy, staging of intra-abdominal malignant lesions, and adhesiolysis for relief of small bowel obstruction. During the 3-year study period, 106 patients underwent 107 procedures, 89 of which were successful. Four patients had substantial complications, two of whom underwent surgical repair. CONCLUSION: A spectrum of procedures may be safely performed with the skills learned from laparoscopic cholecystectomy and without the need for advanced laparoscopic skills such as intracorporeal suturing or tying of knots.

Enteric hyperoxaluria is a commonly seen adverse event after the jejunoileal bypass procedure. The increased concentration of urinary oxalate predisposes bypass patients to various renal complications such as nephrolithiasis and oxalate nephropathy. If not diagnosed and appropriately treated, these complications can lead to irreversible renal damage. We describe 3 patients in whom severe renal complications developed with irreversible compromise of renal function after a jejunoileal bypass. Patients who undergo a jejunoileal bypass require lifelong follow-up with close monitoring of their renal function. Marked decline in renal function mandates prompt investigation and aggressive intervention, including reversal of the jejunoileal bypass if necessary. Chronic renal failure secondary to oxalate nephropathy is preventable and treatable but may require conversion of a jejunoileal bypass to a more current form of bypass.

OBJECTIVE: To determine the indications for use of surgical gastrostomy (SG) and surgical jejunostomy (SJ) as feeding tubes, the complications, and the trends in the use of SG and SJ after the introduction of percutaneous endoscopic gastrostomy (PEG) at our institution in 1981. DESIGN: We conducted a retrospective, population-based cohort study of residents of Olmsted County, Minnesota, who received surgically placed feeding tubes between 1976 and 1989. MATERIAL AND METHODS: The medical records of all Olmsted County residents with surgical placement of a feeding tube during the designated study period were reviewed, and underlying conditions, complications, and survival were analyzed. RESULTS: Of 77 adult patients (mean age, 66 years; 48% women), 54 underwent SG and 23 had SJ. General anesthesia was used in 42 patients (55%). The indications for SG or SJ were stroke in 23 patients, cancer in 19, other central nervous system-related conditions in 16, and other conditions in 19. Among the numerous comorbid conditions, pulmonary disease (N = 44) and cardiac disease (N = 32) were most frequent. The median duration of follow-up was 181 days. Complications occurred in 31 of 54 patients (57%) with SG and in 13 of 23 (57%) with SJ. Of the 117 complications, 15% were considered major. Twenty patients (26%) resumed eating. Survival at 1, 6, and 12 months was 79%, 49% and 36%, respectively. Most deaths were due to the disease for which the feeding tube had been placed. In a Cox proportional hazards regression analysis, only age and hypoxemia were found to be significantly associated with survival. Hypoxemia, type of tube, central nervous system disease as indication for procedure, and previous aspiration were associated with failure to resume eating (P < 0.05). Survival was similar to that for our patients with PEG during the same period. The overall incidence of feeding tube placement increased throughout the study period. CONCLUSION: Patients who require enteral feeding tubes have multiple comorbid conditions that have a major influence on the outcome. The overall incidence of feeding tube placement increased after the introduction of PEG. In patients who require long-term enteral nutrition and are unable to have a feeding tube placed percutaneously, surgically placed feeding tubes have outcomes similar to those reported for patients with PEG.

Our previous experience with vertical (nonbanded) gastroplasty proved disappointing because of unsatisfactory maintenance of weight loss. Vertical banded gastroplasty seemed to be an attractive alternative operation because it provided an externally reinforced (banded) stoma that would not enlarge over time. In this study, our aim was to determine prospectively the results of vertical banded gastroplasty used as a primary, weight-reducing procedure in patients with morbid obesity. Seventy consecutive patients with morbid obesity (mean weight, 139 kg), all of whom had obesity-related complications, underwent vertical banded gastroplasty and prospective follow-up. The hospital mortality was nil, and substantial morbidity occurred in 3% (two patients). Long-term achievement and maintenance of satisfactory weight loss, however, were variable. The median weight loss at 1 year after operation was 36.7 kg or 48% of excess body weight. At 3 years postoperatively, however, weight loss was only 32.4 kg or 40% of excess body weight, and only 38% of patients had achieved and maintained a weight loss of 50% or more of their preoperative excess body weight. Vertical banded gastroplasty caused major changes in eating habits, and many patients were unable to eat red meat or untoasted bread; moreover, approximately 30 to 50% of patients continued to vomit once or more per week. Despite theoretically attractive advantages as a weight-reduction operation, vertical banded gastroplasty does not seem to be the optimal procedure for most patients with morbid obesity.

Prospective data and follow-up information were collected on the initial 200 patients who underwent laparoscopic cholecystectomy at the Mayo Clinic. The operation was completed laparoscopically in all but five patients, who required conversion to laparotomy because of dense scarring or stones in the common bile duct. The median surgical time was 85 minutes. The major postoperative complications were retained stones in the common bile duct (in seven patients), intraperitoneal hemorrhage that necessitated transfusion (in two patients), and intra-abdominal abscess and pulmonary infection (in one patient each). The median hospital stay was 1 day (range, 0 to 8 days), and the median times to full activity and normal employment were 8 days and 12 days, respectively. Laparoscopic cholecystectomy is associated with a low frequency of complications in most patients with symptomatic gallstones and allows a rapid return to normal activity. Currently, laparoscopic cholecystectomy is the treatment of choice for most patients with symptomatic cholelithiasis.
