Perioperative myocardial infarction and risk of death with and without preoperative beta blockers.

This study compares patients who have had a myocardial infarction in the perioperative period who were on perioperative beta blockers with those who had a myocardial infarction and were not on perioperative beta blockers. The charts of 68 patients were reviewed retrospectively. The timing and diagnosis of the myocardial infarction, gender, age, type of surgery, type of anesthesia, diabetics, preoperative medical clearance, and deaths were recorded. A subgroup of patients who had significant bleeding perioperatively or postoperatively were compared with patients with no bleeding problems. From 1998 through 2006, there were 46,003 patients who had surgery and 68 perioperative infarcts. Of the 68 patients, 25 received perioperative beta blockers and 11 died. Of the 43 patients who did not receive beta blockers, 22 died. There was no statistically significant difference when the patients were analyzed for concomitant bleeding or nonbleeding with regards to survival and beta blockers.

Intestinal obstruction and ileus: role of computed tomography scan in diagnosis and management.

A significant proportion of patients with intestinal obstruction will be evaluated with a CT scan of the abdomen. This study presents a group of 97 patients diagnosed with mechanical obstruction or ileus on CT scan over a 16-month period at a community based teaching hospital and follows the further management of these patients. Our study shows that 43.3 per cent of patients with mechanical obstruction, diagnosed by CT scan, eventually needed surgical treatment. On the other hand, even when CT indicates ileus, 20 per cent of these patients may still require surgical intervention.

An eight-year analysis of surgical morbidity and mortality: data and solutions.

In this article, a reproducible process for presenting, analyzing, and reducing early and late surgical morbidity and mortality (M and M) is detailed. All M and M cases presented from 1998 through 2005 at Monmouth Medical Center were categorized. Residents and nurses were empowered to report the complications. The five major categories were overwhelming disease on admission, delays in treatment, diagnostic or judgment complications, treatment complications, and technical complications. From the 53,541 operations performed over 8 years, 714 patients were presented, which included 147 deaths and 1,132 category entries. The most common problems were technical complications in 474 (66.4%) patients. The data have generated actionable solutions, many with low barriers to adoption, resulting in safer, less expensive surgical management. Surgical outcome benchmarks have been established and are used for credentialing surgeons. The "Hostile Abdomen Index" has been developed to assess the safest choice for abdominal operative access, pre- and intraoperatively. We explained the real-time process that generated solutions for the entire department as well as changes relevant to residency training and individual operative techniques.

Inadvertent enterotomy in minimally invasive abdominal surgery.

BACKGROUND: Inadvertent enterotomy (IE) in laparoscopic abdominal surgery is underreported. Patients with a prior history of laparotomy are at significantly increased risk of enterotomy if another operation is needed. The incidence of enterotomy in laparoscopic surgery may even be greater than that during an open procedure and may go unrecognized due to the limited field of vision. The purpose of this study was to report the incidence of inadvertent enterotomy in a variety of laparoscopic abdominal procedures at our institution and discuss ways to minimize the risk of this complication. METHODS: Using the data from morbidity and mortality conferences, we retrospectively reviewed all complications from 3,613 consecutive patients who had laparoscopic abdominal surgery from November 1998 through November 2004. Patients with inadvertent enterotomy were divided into 4 groups according to the type of laparoscopic procedure. Inadvertent enterotomy was defined as any transmural penetration of any part of the intestine. All inadvertent enterotomies that occurred during laparoscopic abdominal surgery were analyzed for mechanism of injury and method of repair, whether diagnosis was made intraoperatively or postoperatively, clinical presentation, conversion rate, and whether a second procedure was necessary. RESULTS: Laparoscopic operations were performed in 3,613 persons. Patients diagnosed with IE were divided into 4 groups: Group #1: cholecystectomy; Group #2: all patients requiring intestinal resection with or without primary anastomosis; Group #3: patients with any type of hernia repair; Group #4: all patients that had adhesiolysis as a primary indication for the operation. The incidence of IE according to each group was 0.39% (8/2,016), 0.8% (3/375), 1.9% (6/312), 100% (4/4), respectively. Twenty patients had 21 inadvertent enterotomies (4 men, 16 women; mean age, 60.9 years). One patient had 2 operations and had an enterotomy both times. Four patients (4/21, 19%) with unrecognized IE were diagnosed postoperatively. The overall incidence of IE was 0.58%. No deaths occurred. CONCLUSION: Inadvertent enterotomy in laparoscopic abdominal surgery is especially dangerous if unrecognized during the primary operation. The incidence of IE can be significantly reduced with careful individualized risk assessment. Only surgeons who are trained in advanced laparoscopy should attempt complicated cases and must always be wary of possible bowel injury. Any patient with signs of peritonitis, sepsis, or increased abdominal pain after laparoscopic surgery must promptly be investigated. The department culture of intraoperative cooperation helped improve outcomes.

Reducing medication errors in a surgical residency training program.

Medication errors contribute to in-hospital morbidity and mortality. Teaching hospitals and the surgical residency training programs they support should take proactive steps to reduce error frequency. In order to accomplish meaningful error reduction, we must first define the scope and nature of the problem. Pharmacists at the Monmouth Medical Center prospectively recorded medication prescribing errors made by surgical residents during 2 years. These data were reviewed to determine the types of medication errors made most frequently by surgical house officers. Seventy-five medication-prescribing errors were made by surgical house staff in the years 2001 and 2002. Thirty-three of these errors involved orders for antibiotic therapy. Errors that could not be directly attributed to knowledge deficits were responsible for 36 of the 75 errors (48%), whereas specific knowledge deficits were responsible for 39 of the 75 errors (52%). Twentyeight of the 36 errors not directly attributable to knowledge deficits (78%) were made at the postgraduate year one level, whereas only 15 of the 39 knowledge deficit errors (38%) were made at the postgraduate year one level. Though targeted education to address specific knowledge deficits may substantially reduce the occurrence of "knowledge deficit" medication errors within surgical residency training programs, more costly measures such as the implementation of physician computerized order entry will likely be needed to reduce maximally the frequency of medication ordering errors. Many prescribing errors cannot be attributed to specific knowledge deficits.

Hostile Abdomen Index Risk stratification and laparoscopic complications.

BACKGROUND: Common life-threatening complications associated with laparoscopy, including bleeding and inadvertent enterotomy, are described in the literature. We investigated the application of the Hostile Abdomen Index related to these complications. We hypothesize that the preoperative score may guide a surgeon in risk stratification. METHODS: We used data from Monmouth Medical Center morbidity and mortality conferences and reviewed bleeding and enterotomy complications in laparoscopic abdominal surgery. Complications were tracked using the Hostile Abdomen Index compared between 2 periods: published early experience with laparoscopic surgery (1998-2003) and unpublished late experience (2004-2010). The index ascribes a number (1-4) before a laparoscope is inserted and another number (1-4) after the laparoscope is inserted into the abdomen. RESULTS: From 1998 to 2010, 43 patients had bleeding complications (0.45%) and 28 had inadvertent enterotomies (0.29%). There was no difference in bleeding between the early and late experiences. Enterotomy complications decreased in the late experience (P < .001). Our rescue success was 97.2% over 13 years. Those laparoscopic cases with high preoperative scores (3-4) had a higher rate of conversion to open procedures. CONCLUSIONS: The Hostile Abdomen Index can be used to track 2 potentially life-threatening laparoscopic complications. The index score has been explained to our surgeons on numerous occasions. A higher chance of bleeding and enterotomy or risk stratification correlates with a preoperative 3 or 4 score and may lead to a more cautious approach toward initial laparotomy or earlier conversion.

Totally laparoscopic gastrectomy for gastric cancer.

BACKGROUND AND OBJECTIVES: Recent studies have supported minimally invasive techniques as a viable alternative to open surgery in the treatment of gastric cancer. The goal of this study is to review our institution's experience with totally laparoscopic gastrectomy for the treatment of both early- and advanced-stage gastric cancer. METHODS: A retrospective study was conducted to examine the short-term outcomes of laparoscopic gastrectomy performed at Monmouth Medical Center between May 2003 and June 2012. We reviewed postoperative complications, surgical margins, number of resected lymph nodes, estimated blood loss, length of stay, narcotic use, and recurrence rate. RESULTS: Forty patients were included in the study. There were 21 cases of adenocarcinoma, 15 cases of gastrointestinal stromal tumor, 2 cases of carcinoid, 1 case of small cell neuroendocrine tumor, and 1 case of squamous cell carcinoma. The mean operative time was 220 minutes (range, 67- 450 minutes). The median length of stay was 6 days (range, 1-37 days). The mean number of harvested lymph nodes was 11. Early postoperative complications occurred in 7 patients and included anastomotic stricture, wound infection, intra-abdominal abscess, bowel obstruction, and esophageal pneumatosis. There were two deaths. The Kaplan-Meier 5-year overall and recurrence-free survival rate for all cases of adenocarcinoma was 63.2%. CONCLUSIONS: Totally laparoscopic gastrectomy is a reasonable option for the treatment of gastric malignancy, with early data showing acceptable survival rates and perioperative outcomes. Large-scale randomized trials are still needed to confirm oncologic equivalency to open gastrectomy in patients with advanced disease.

Treatment and outcomes of iatrogenic colon perforations at a community teaching hospital.

Despite the growing expertise in colonoscopy, it remains subject to complications. The previously published rate of colonoscopic perforation is 0.82 per 1000 examinations. The objective of this study was to describe the experience and management of colonoscopic perforations. A retrospective review of cases from a database of surgical complications was searched for perforations postcolonoscopy from January 1, 2001, to December 31, 2010 at a 527-bed community teaching hospital. Eighteen patients were identified, 11 of whom underwent examination at our institution. Ages ranged from 40 to 91 years with a mean age of 71 years. Eleven of the 18 patients were female and seven were male. Main outcome measures were treatment approach, treatment complications, and mortality. A total of 18 patients were identified in this database. Of these 18 patients, 11 underwent colonoscopy at our institution. During the studied time period, 7578 colonoscopies were performed at our hospital. The majority of the perforations were located in the rectosigmoid colon. Seventeen patients were treated with surgical exploration of the abdomen. Ten patients experienced complications postoperatively. There were two deaths in our series. Only cases in which the colonoscopy was performed at our institution were used when making incidence calculations. The incidence of perforation in our series was significantly higher than previously reported rates. When the perforation was discovered and treated within 24 hours, the patient was rescued. Timely recognition of surgical complications is critical in preventing patient mortality.

Surgical site infections: incidence and trends at a community teaching hospital.

BACKGROUND: There has been increased national attention on methicillin-resistant Staphylococcus aureus (MRSA) and surgical site infections (SSIs) highlighted by the media, the public, and federal agencies. It was therefore considered important to analyze the trends and incidence of inpatient detected SSIs and associated resistant organisms at our own institution. METHODS: The analysis reflects the cultures and sensitivities of SSI on the surgical services at Monmouth Medical Center, a 527-bed community teaching hospital, from January 2003 through December 2007. The SSIs included in the study were those detected in hospitalized patients. RESULTS: There were 312 surgical patients who developed SSIs. Contrary to observed national trends, our study demonstrated a statistically significant decrease in the incidence of MRSA among all the surgical services. We also noted a statistically significant decrease trend of SSIs in orthopedic surgery. The 312 patients' cultures yielded 399 bacterial strains. The most common strains varied with the service. Overall, the most common isolate identified was Staphylococcus species, numbering 143% or 35.8% of all isolates. MRSA was identified in 46 SSIs and 8 SSIs were positive for vancomycin-resistant enterococci (VRE). CONCLUSIONS: Only a hospital-specific SSI analysis can help focus improvement with clinical impact. The scrutiny of SSI analysis has highlighted SSI problems in the pediatric and orthopedic surgery services that have been addressed.

Ten-year review of groin laparoscopy in 1001 pediatric patients with clinical unilateral inguinal hernia: an improved technique with transhernia multiple-channel scope.

PURPOSE: The purpose of this 10-year review of data is to verify the effectiveness, safety, and appropriate age group for using a multichannel scope during inguinal herniorrhaphy in pediatric patients with clinical unilateral inguinal hernia to evaluate for contralateral patent processus vaginalis (CPPV). METHODS: The data evaluated are age, sex, negative findings, positive findings, false positives, false negatives, recurrences, date of recurrence, and complications. Patients who clinically had bilateral hernias or were born prematurely were excluded. A 5-mm, 30° multichannel scope was used through the ipsilateral open hernia sac to explore the contralateral internal ring. A Fogarty catheter was used through one of the channels of the scope to probe the contralateral side in instances of questionable patent processus vaginalis. RESULTS: One thousand one patients were studied, and a total of 237 CPPVs (23%) were identified. The highest incidence of CPPV was found in those patients younger than 1 year (44%). Contralateral patent processus vaginalis was identified and ligated in 34% of patients younger than 2 years, 20% in patients 2 to 8 years old, and 17% of patients 9 to 18 years old. There were no false positives and 6 false negatives (0.6%) of the contralateral side. There were 3 (0.3%) recurrent inguinal hernias of the ipsilateral side and no complications. CONCLUSIONS: The use of a multichannel scope through the ipsilateral open hernia sac during inguinal herniorrhaphy in pediatric patients with clinical unilateral inguinal hernia to evaluate for CPPV proved to be effective, cost-effective, and safe. Our procedure eliminated any additional scars and the cost of trocars and permitted us to probe the contralateral internal ring. Unnecessary open exploration was spared in 56% of children younger than 1 year and proved to be useful in all pediatric patients up to the age of 18 years.

VATS intraoperative tattooing to facilitate solitary pulmonary nodule resection.

INTRODUCTION: Video-assisted thoracic surgery (VATS) has become routine and widely accepted for the removal of solitary pulmonary nodules of unknown etiology. Thoracosopic techniques continue to evolve with better instruments, robotic applications, and increased patient acceptance and awareness. Several techniques have been described to localize peripheral pulmonary nodules, including pre-operative CT-guided tattooing with methylene blue, CT scan guided spiral/hook wire placement, and transthoracic ultrasound. As pulmonary surgeons well know, the lung and visceral pleura may appear featureless on top of a pulmonary nodule. CASE DESCRIPTION: This paper presents a rapid, direct and inexpensive approach to peripheral lung lesion resection by marking the lung parenchyma on top of the nodule using direct methylene blue injection. METHODS: In two patients with peripherally located lung nodules (n = 3) scheduled for VATS, we used direct methylene blue injection for intraoperative localization of the pulmonary nodule. Our technique was the following: After finger palpation of the lung, a spinal 25 gauge needle was inserted through an existing port and 0.1 ml of methylene blue was used to tattoo the pleura perpendicular to the localized nodule. The methylene blue tattoo immediately marks the lung surface over the nodule. The surgeon avoids repeated finger palpation, while lining up stapler, graspers and camera, because of the visible tattoo. Our technique eliminates regrasping and repalpating the lung once again to identify a non marked lesion. RESULTS: Three lung nodules were resected in two patients. Once each lesion was palpated it was marked, and the area was resected with security of accurate localization. All lung nodules were resected in totality with normal lung parenchymal margins. Our technique added about one minute to the operative time. The two patients were discharged home on the second postoperative day, with no morbidity. CONCLUSION: VATS with intraoperative tattooing is a safe, easy, and accurate technique to streamline and efficiently resect solitary pulmonary nodules.

When should a surgical resident call an attending surgeon?

BACKGROUND: Many interactions exist between surgical residents and attending surgeons, where residents debate whether they should "bother" to call an attending. Several instances have occurred when a senior resident or an attending has not been notified about a patient's status by a junior resident. Because of poor communication, care might be delayed, and surgeons and patients' relatives might not be informed of a change in status. Sometimes the resident's initial management was different than an attending's management. Communication issues were raised at our weekly Morbidity & Mortality conference. We decided to investigate the range of judgment as to when a resident should notify an attending surgeon. STUDY DESIGN: The objective was to investigate the range of judgment as to when a surgical resident should notify an attending surgeon. The purpose of this study was to determine the clinical circumstances when surgical residents should contact an attending surgeon directly or leave a message with the service. To investigate communication questions, we developed a survey of 34 clinical circumstances in which a surgical resident could call an attending. Sixteen residents and 16 attendings completed the survey entitled "Conditions where a surgical resident should consider contacting the surgical attending." From the information obtained from this study, a "must leave message" and "must speak to directly" list were created to guide residents as to when to call an attending. RESULTS: A significant difference existed in the answers provided by residents and attendings. Residents and attendings agreed universally that an attending should be spoken to directly for 2 reasons: cardiopulmonary arrest and death. We created a "must speak to directly" list based on the attendings' answers. This list includes 10 clinical circumstances in which a surgical resident should speak directly with an attending regarding patient issues. Likewise, a "must leave message" list was created of an additional 8 reasons when a surgical resident must at least call the service of an attending and leave a message. CONCLUSION: The purpose of our study was to help standardize communication between surgical residents and attendings regarding patient status. With these 2 standardized "must" lists, residents will have less uncertainty or hesitation to awaken an attending at night. This finding should improve the communication skills of surgical residents and ultimately improve the quality of patient care.

Oncologic and aesthetic results following breast-conserving therapy with 0.5 cm margins in 100 consecutive patients.

The purpose of this study was to evaluate the oncologic and aesthetic results of patients undergoing breast-conserving therapy with 0.5 cm surgical margins and determine the factors that influence the need for reconstruction. One hundred consecutive patients who underwent breast-conserving surgery with 0.5 cm surgical margins followed by radiotherapy for invasive cancer and ductal carcinoma in situ (DCIS) were followed prospectively and evaluated for recurrence and aesthetic result. Thirteen patients underwent reexcision to achieve a 0.5 cm margin. Factors including breast size, location of the tumor, specimen size and volume, tumor size and volume, and TNM stage, if axillary dissection or reexcision were required, were included in the analysis. Aesthetic evaluation consisted of both patient rating and an independent observer rating on a 10-point scale that assessed volume, shape, symmetry, areola/nipple, and scar. Of the 100 patients that underwent breast-conserving therapy, the overall aesthetic results revealed that 8% of the patients scored themselves seven or less, another 8% were scored seven or less by the independent observer, and another 7% were scored seven or less by both the patient and the observer. Of these patients, only one proceeded to have a reconstructive procedure. Analysis of variance revealed a significant correlation between tumor size (cm(2)) and an aesthetic score of seven or less (p = 0.023), and specimen volume (cm(3)) and an aesthetic score of seven or less (p = 0.039). Chi-squared analysis revealed a significant difference (chi(2) = 4.39, p < 0.5) in the aesthetic result in patients with stage IIA disease. Other independent factors such as age, breast size, location of the tumor, axillary dissection, and reexcision did not influence the overall aesthetic result. A Pearson correlation of patient and independent observer ratings showed a positive correlation (r = 0.4; 95% confidence interval [CI] 0.19-0.57) between the two groups. There were zero local recurrences of breast cancer during the study period. Our results demonstrate that following breast-conserving therapy with a minimum of 0.5 cm resection margins, it is possible to achieve excellent oncologic and aesthetic results. Patients with large tumors that require a large volume of resection or with stage IIA disease should be considered for reconstructive evaluation.
