ABSTRACT: BACKGROUND: Infection can be a devastating complication associated with prosthetic incisional hernia repair. It is unclear whether the type of mesh used affects the risk of infection. METHODS: A retrospective review was performed of all patients who underwent elective incisional hernia repair with permanent prosthetic mesh between January 1, 2000, and August 1, 2007. RESULTS: A total of 176 patients underwent elective incisional hernia repair with mesh. The overall infection rate with the use of goretex (Flagstaff, AZ, USA) was 12 of 86 (14%) and 2 of 90 (2.2%) in cases in which nongoretex material was used (P = .016). In the goretex group, infection rates were significantly higher in open versus laparoscopic cases (26.5% vs 5.8%, P = .030). Methicillin-resistant Staphylococcus aureus was the most common organism recovered. CONCLUSIONS: The risk of mesh infection with the use of goretex was found to be higher than with the use of nongoretex mesh. Laparoscopic placement of goretex reduces this risk of infection. No significant differences in recurrence rates were found.

ABSTRACT: BACKGROUND: Most studies regarding laparoscopic ventral hernia repair (LVHR) have merged primary hernias (PHs) and secondary (incisional) hernias (SHs) into one group of ventral hernias. This grouping could produce falsely favorable results for LVHR. Our objective was to review and compare the outcomes of laparoscopic repair of PHs and SHs. METHODS: A retrospective chart review of patients from 2000 to 2010 identified the cases of LVHR at two affiliated institutions. The demographics, comorbidities, type of hernia (PH versus SH), and short- and long-term complications were analyzed. The postoperative pain, cosmetic satisfaction, and Activities Assessment Scale scores were assessed by telephone survey. RESULTS: A total of 201 cases of LVHR were identified: 73 PHs (36%) and 128 SHs (64%). No difference was found in the mean age between the two groups. The PH group had a greater percentage of black patients (34% versus 14%; P < 0.05), and the SH group had a greater percentage of white patients (85% versus 65%; P < 0.05). More female patients had SHs (34% versus 14%; P < 0.05), and more male patients had PHs (86% versus 66%; P < 0.05). More patients in the SH group had chronic obstructive pulmonary disease (19% versus 7%; P < 0.05) and prostate disease (32% versus 9%; P < 0.05). Overall, the SHs were larger (37.9 ± 4.9 cm(2)versus 11.5 ± 1.9 cm(2); P < 0.01). No differences were found in early postoperative complications, including pneumonia, urinary tract infection, surgical site infection, and seromas between the two groups. However, those with SHs had a greater incidence of recurrence (16% versus 5%; P < 0.05) and mesh explantation (7% versus 0%; P < 0.05). The patients who also underwent SH repairs had greater postoperative pain scores when followed up for a median of 25 mo than those who underwent PH repairs when followed up for a median of 24 mo (3.5 ± 0.4 versus 1.8 ± 0.4; P < 0.05). More patients in the SH group had chronic pain issues (26% versus 5%; P = 0.0003) and had lower satisfaction scores (7.5 ± 0.3 versus 8.6 ± 0.3; P < 0.05). Overall, the Activities Assessment Scale scores were not significantly different. CONCLUSIONS: Our data have demonstrated that PHs and SHs are different. LVHR of SHs is associated with increased recurrence, greater postoperative pain scores, chronic pain issues, and lower patient satisfaction scores. We recommend that future studies evaluate LVHR for PHs separate from those for SHs.

ABSTRACT: Pancreatic trauma is rare with an incidence between one and two percent in patients with abdominal trauma. Morbidity and mortality,
however, are significant with rates approaching 40–45% in some reports. The majority of patients with injuries to the pancreas
have associated trauma to other organs which are primarily responsible for the high mortality rate. The continuity of the
main pancreatic duct is the most important determinant of outcome after injury to the pancreas. If there is no evidence of
ductal injury on fine-cut CT or on ERCP, nonoperative management is chosen. The indications for operative management are as
follows: (1) peritonitis on physical examination; (2) hypotension and a positive FAST; and (3) evidence of disruption of the
pancreatic duct on fine-cut CT or on ERCP. After exposure and evaluation of the extent of injuries to the pancreas and duodenum,
a decision must be made on the procedure. For pancreatic contusions, hematomas, or small lacerations, simple external drainage
or pancreatorrhaphy with drainage can be performed. For ductal transection at the neck, body, or tail, the procedure of choice
is a distal pancreatectomy or Roux-en-Y distal pancreatojejunostomy. If the patient has suffered a ductal transection at the
head of the pancreas without injury to the duodenum, a Roux-en-Y distal pancreatojejunostomy or anterior Roux-en-Y pancreatojejunostomy
is the operation of choice. For combined pancreatoduodenal injuries, the options are repair and drainage, diversion via a
pyloric exclusion procedure, or pancreatoduodenectomy. Complications of pancreatic injuries include fistulas and intra-abdominal
abscesses, and an occasional pancreatic pseudocyst. Key Words

ABSTRACT: Traditionally, laparoscopic ventral hernia repair (LVHR) is performed by placing the trocars on one side of the abdomen. Tacking the mesh on the operative side can be challenging. We hypothesized that mesh shift may occur as a result of this approach. We define mesh shift as any mesh off-center, where the center is the hernia defect. Our objectives were to evaluate whether mesh shift occurs after LVHR, and to develop a grading system to describe this phenomenon.
We conducted a retrospective review of patients who underwent LVHR from 2000 to 2010. We examined patient demographics, comorbidities, radiographic data, surgical data, and outcomes. Using analysis of variance, we analyzed continuous data; we used Chi squared to analyze categorical data. Of the 201 patients, we reviewed 78 postoperative computed tomography (CT) scans. Two surgeons measured mesh overlap of the fascia bilaterally at the level of the hernia defect. We compared a ratio of the two sides of overlap (least overlap/greatest overlap) and classified patients into four grades: grade I, no mesh shift (ratio of 0.5-1.00); grade II, mild mesh shift (ratio of 0.20-0.49); grade III, moderate mesh shift (>0-0.19); and grade IV, major mesh shift with recurrence (<0). Any recurrence was classified as a grade IV shift.
A total of 48% of patients had mesh shift (grade II = 23%; grade III = 10%; and grade IV = 17%). In 92% of the patients with mesh shift, the mesh migrated away from the port placement site, resulting in decreased mesh/fascial overlap. Patients in the four groups had similar demographics, comorbid conditions, hernia characteristics, operative technique, and outcomes (excluding recurrences, which were all grade IV by definition). Whereas differences in time to follow-up CT scan in the different grades were not statistically significant, there was a trend toward increasing shift with time (mean: grade I, 20 mo; grade II, 38 mo; grade III, 50 mo; and grade IV, 26 mo; P = 0.07). A total of 26 patients (33%) had multiple postoperative CT scans. With time, it appears that mesh tended to shift with time (grade I, 68%-46%; grade II, 12%-19%; grade III, 12%-8%, and grade 4, 8%-23%).
Mesh can shift from the ideal central placement after LVHR. Mesh tends to shift away from the operative side and recurrences tend to occur on the operative side. Mesh shift may be a precursor to hernia recurrence. Recurrence may be a two-step process, beginning first with intra-operative mesh shift followed by additional factors (such mesh contraction) that may accentuate the shift and lead to recurrence. Potential solutions include increasing mesh overlap (≥ 6 cm), performing transcutaneous closure of central defect, securing trans-fascial sutures before tacking, placing operative side tacks first, and consider placing contralateral ports to secure the mesh.

ABSTRACT: The aim of this technical report is to investigate the safety, efficacy, and outcome of transcutaneous closure of central defects (TCCD) for laparoscopic incisional hernia repair (LIHR).
Twenty-two patients with incisional hernias underwent a LIHR-TCCD repair. After clearance of the abdominal wall from adhesions, laparoscopic central closures were performed transcutaneously with 0-polypropelene sutures placed every 1 cm of the defect starting at the cranial-most edge of the hernia and ending at the caudal-most edge of the hernia. A standard LIHR was performed with coated polyester mesh placed with at least 6 cm of overlap with mesh on all borders. Transfascial sutures with 0-polypropelene sutures were placed every 4 cm circumferentially, and titanium tacks were used to secure the mesh to the peritoneum every 1 cm.
The mean age was 52 years and the mean body mass index was 35 kg/m. The mean hernia defect was 4.7 cm×7.2 cm with a mean area of 37 cm. There were no mortalities and no major perioperative morbidities. Minor complications included 2 (9%) cases of pneumonia/pneumonitis. There were no clinically significant seromas, no radiographic or clinical eventrations, and no hernia recurrences with a mean follow-up of 21 months.
LIHR-TCCD is safe and technically feasible in incisional hernias of width <10 cm. By closing the central defect, seromas and eventrations can be reduced.

ABSTRACT: Stump appendicitis is an underreported and poorly defined condition. It is the development of obstruction and inflammation of the residual appendix after appendectomy. This is a review of the basic clinical, pathological, and surgical significance of stump appendicitis, and the "critical view" required for prevention.
PubMed MEDLINE search was performed using terms "stump appendicitis" and "retained appendix" to obtain reported cases of stump appendicitis. Sixty-one cases were identified. Each case was charted based on 14 variables. Data were analyzed.
Stump appendicitis warrants early detection. Patients can present with abdominal pain, nausea, and vomiting. A prior history of appendectomy can delay the diagnosis. A diagnosis can be made with an abdominal ultrasound or computed tomography scan. If treated early, laparoscopic or open completion appendectomy can be performed. If diagnosis is delayed and perforation is found, extensive resection is often required. A "critical view," as described in this article, is key for prevention.

ABSTRACT: Relaparotomy after emergency surgery for nontrauma intraabdominal catastrophes (NTIAC) is morbid. Our objective was to identify patients who likely will need on-demand relaparotomy after surgery for NTIAC.
A retrospective chart review of patients from 1998 to 2008 identified cases of NTIAC surgery with fascial closure. Demographics, comorbidities, intraoperative findings, morbidity, and mortality were analyzed. Relaparotomy was defined as any return to the operating room with surgical re-entry of the abdominal cavity.
A total of 129 patients underwent NTIAC surgery with fascial closure. Twenty-nine patients (22%) required relaparotomy and 100 patients (78%) did not. Multivariate analysis identified the following predictors of relaparotomy: peripheral vascular disease (P = .04), alcohol abuse (P = .02), body mass index of 29 kg/m(2) or greater (P = .04), the finding of any ischemic bowel (P = .02), and operating room latency of 60 hours or longer (P = .01). Patients with 2 or more of these predictors had a 55% risk of relaparotomy whereas patients with fewer than 2 of these predictors had a 9% risk (P < .001).
Patients whose fascia is closed during NTIAC surgery do worse when they require relaparotomy. We have identified preoperative and intraoperative predictors that may help identify patients at high risk of on-demand relaparotomy.

ABSTRACT: Duplication of the vas deferens is the identification of a second vas deferens within the spermatic cord; it is a rarely reported congenital anomaly. Duplicate vas deferens should not be confused with double vas deferens that describes ipsilateral renal agenesis with a blind ureter ending in the ejaculatory system.
We present a case of duplicated vas deferens, and a PubMed Medline (National Library of Medicine) search was performed using the terms "[duplicated OR double]" and "vas deferens". Nineteen papers for a total of twenty-two cases (including ours) were identified.
Duplication of vas deferens is a rare finding; it is likely under-reported and underrecognized. Failure to recognize this variation can result in injury to the vas deferens or an ineffective vasectomy. Following identification of a suspected duplicated vas deferens, the structure should be tracked from the internal ring down to the epididymis and intra-operative Doppler should be performed. Post-operatively, renal and bladder imaging can be considered though there have been no reported cases of non-testicular genito-urinary anomalies associated with duplicated vas deferens.

ABSTRACT: Damage-control laparotomy, initially developed for trauma patients, has expanded into the general surgery arena. Little evidence exists regarding the utility of damage-control celiotomy (DCCT) in elderly nontrauma patients. Our objective was to review the management and outcomes of DCCT in elderly patients with intra-abdominal catastrophes.
Retrospective chart review from 1998 to 2008 identified cases of DCCT. Demographics, comorbidities, surgical techniques, morbidity, long-term disposition, and mortality were analyzed.
From 210 patients with emergency surgeries, 88 (42%) patients with DCCT were identified, 33 (38%) were greater than 65 years old and 55 (63%) were ≤ 65 years old. The average APACHE IV score for the elderly was 84 ± 2 versus 68 ± 2 for the younger group (p < .001). Elderly patients had significantly higher comorbidites with respect to cardiovascular, pulmonary, and renal disease. When comparing the 2 groups, there were no significant differences in-hospital or intensive care unit lengths of stay or ventilator days. There were also no significant differences in complications and disposition. Using Cox proportional hazards analysis, age was not an independent predictor of 30-day mortality.
Age is not an independent predictor of worse outcomes in patients managed by the DCCT technique after intra-abdominal catastrophes. This management technique should be considered for elderly patients who require DCCT.

ABSTRACT: Perioperative atrial arrhythmias (PAAs) in noncardiothoracic patients have poorly defined risk factors and management.
The surgical intensive care unit database was queried for patients who developed PAAs from 2008 to 2009. Demographics, comorbidities, preoperative data (electrocardiography, chest x-rays, laboratory results), medications, intraoperative variables, management, and outcomes of atrial arrhythmias were collected. Controls were randomly chosen in a 3:1 ratio. Comparisons were performed using χ² tests, Student's t tests, or nonparametric comparisons as appropriate. Multivariate logistic regression was performed.
Five hundred sixty-one patients were admitted to the surgical intensive care unit. Three hundred fifty-four (63%) had noncardiothoracic surgery, and 30 (8.5%) developed PAAs. The mean age of patients with PAAs was 66 ± 7.3 years, compared with 64 ± 11 years for controls (P = NS), with most patients undergoing general (60%) and vascular (33%) surgery. PAA patients were more likely to have coronary artery disease (P = .029), cardiomegaly (P = .011), and premature atrial contractions (P = .016) and to take aspirin (P = .010). On multivariate logistic regression, predictors of atrial arrhythmias were premature atrial contractions, preoperative hypokalemia, intraoperative adverse events, and cardiomegaly. Most PAA patients received amiodarone (63%). Ten percent required electrical cardioversion, and 26% received anticoagulation. PAA patients had significantly longer intensive care unit lengths of stay (P = .032).
Coronary artery disease, cardiomegaly, hypokalemia, and premature atrial contractions were significantly associated with PAAs in noncardiothoracic patients. Prospective studies are needed to define treatment guidelines.

ABSTRACT: Methicillin-resistant Staphylococcus aureus (MRSA) surgical site infections (SSIs) increase morbidity and mortality. We examined the impact of the MRSA bundle on SSIs.
Data regarding the implementation of the MRSA bundle from 2007 to 2008 were obtained, including admission and discharge MRSA screenings, overall MRSA infections, and cardiac and orthopedic SSIs. Chi-square was used for all comparisons.
A significant decrease in MRSA transmission from a 5.8 to 3.0 per 1,000 bed-days (P < .05) was found after implementation of the MRSA bundle. Overall MRSA nosocomial infections decreased from 2.0 to 1.0 per 1,000 bed-days (P = .016). There was a statistically significant decrease in overall SSIs (P < .05), with a 65% decrease in orthopaedic MRSA SSIs and 1% decrease in cardiac MRSA SSIs.
Our data demonstrate that successful implementation of the MRSA bundle significantly decreases MRSA transmission between patients, the overall number of nosocomial MRSA infections, and MRSA SSIs.

ABSTRACT: The role of acellular dermal matrix (ADM) in abdominal wall reconstruction (AWR) is unclear. The aim of this study was to review the management, complications, and long-term outcomes of AWR using ADM in a large surgical cohort.
Retrospective chart review of patients undergoing AWR using ADM from 2004 to 2007 was performed. Demographic data, comorbidities, complications, and long-term outcomes were collected.
There were 77 cases in 68 patients with mean age of 61.1 +/- 1.4 years. The most common indication was infected fascia (n = 19 [25%]). Wound closure was achieved in 75% of the cases via primary (n = 26 [45%]), secondary intention (n = 17 [29%]), or skin graft (n = 15 [26%]). Nonprimary closure was achieved in 5.7 +/- .7 months. There were 32 perioperative (39%) and 33 long-term (43%) complications. Over a mean follow-up period of 13.2 +/- 1.5 months, the hernia recurrence rate was 27% (n = 21).
Although ADM is a viable option in AWR, the high hernia recurrence rate warrants a continued search for alternative biologic materials to improve outcomes.

ABSTRACT: Little is known regarding the morbidity and mortality of the open abdomen technique in older nontrauma patients.
A retrospective chart review identified cases of emergency laparotomy in which open abdomens were used.
Eighty-eight patients with open Acute Physiology and Chronic Health Evaluation (APACHE) abdomens were identified. An overall mortality rate of 34%, consistent with mortality predicted by APACHE IV score, was seen. Common complications included ventilator-associated pneumonia (30%) and acute renal failure (22%). A perioperative APACHE IV score of greater than 65 and an albumin level less than 2.5 g/dL were found to predict an increased likelihood of long-term assisted care placement after discharge from the acute care setting.
The use of the open abdomen technique in older nontrauma patients carries acceptable morbidity and mortality given the acuity of disease. Focus on ventilator-associated pneumonia prevention and aggressive fluid resuscitation to avoid acute renal failure may improve outcomes. Need for long-term assisted care placement can be predicted early after admission based on the APACHE IV score or albumin level.

ABSTRACT: A 10-year review of temporary intravascular shunts (TIVS) at a regional trauma center.
Retrospective chart review of all patients treated with temporary intravascular shunts from January 1, 1997 to January 1, 2007.
Seven hundred eighty-six patients were treated for vascular injuries. Sixty-seven (9%) had a total of 101 (72 arterial, 29 venous) TIVS placed to facilitate damage control or to allow for reconstruction of Gustilo IIIc fractures or limb replantation. Seven patients who, on trauma day 0, died or had an extremity which was deemed unsalvageable were excluded. Of 60 patients who met inclusion criteria, seven died from TBI (3%), MOF (3%), sepsis (2%), deceleration of care (2%), and loss of airway (2%), which was deemed preventable.
TIVS have a shunt thrombosis rate of 5%, amputation rate of 18%, overall survival of 88%, and combination limb/patient survival rate of 73%. TIVS have an established role primarily in patients requiring either "damage control" for exsanguination or temporary vascular conduits during stabilization of Gustilo IIIc fractures. Truncal injuries are associated with the highest mortality likely due to accompanying multisystem trauma.

ABSTRACT: Pancreatic trauma presents challenging diagnostic and therapeutic dilemmas to trauma surgeons. Injuries to the pancreas have been associated with reported morbidity rates approaching 45%. If treatment is delayed, these rates may increase to 60%. The integrity of the main pancreatic duct is the most important determinant of outcome after injury to the pancreas. Undiagnosed ductal disruptions produce secondary infections, fistulas, fluid collections, and prolonged stays in the intensive care unit and hospital. This article analyzes the epidemiology, diagnostic approaches, options for nonoperative and operative management, and outcome after blunt and penetrating pancreatic trauma.
