RESUMO
Guidelines are increasingly determining the decision process in day-to-day clinical work. Guidelines describe the current best possible standard in diagnostics and therapy. They should be developed by an international panel of experts, whereby alongside individual experience, above all, the results of comparative studies are decisive. According to the results of high-ranking scientific studies published in peer-reviewed journals, statements and recommendations are formulated, and these are graded strictly according to the criteria of evidence-based medicine. Guidelines can therefore be valuable in helping particularly the young surgeon in his or her day-to-day work to find the best decision for the patient when confronted with a wide and confusing range of options. However, even experienced surgeons benefit because by virtue of a heavy workload and commitment, they often find it difficult to keep up with the ever-increasing published literature. All guidelines require regular updating, usually every 3 years, in line with progress in the field. The current Guidelines focus on technique and perioperative management of laparoscopic ventral hernia repair and constitute the first comprehensive guidelines on this topic. In this issue of Surgical Endoscopy, the first part of the Guidelines is published including sections on basics, indication for surgery, perioperative management, and key points of technique. The next part (Part 2) of the Guidelines will address complications and comparisons between open and laparoscopic techniques. Part 3 will cover mesh technology, hernia prophylaxis, technique-related issues, new technologic developments, lumbar and other unusual hernias, and training/education.

Inguinal hernia repair is a common surgical procedure, but the most effective surgical technique remains controversial. The evolution of laparoscopic techniques has allowed reproduction of open preperitoneal repair via an endoscopic total extraperitoneal (TEP) approach. More recently, the advent of comprehensive training in laparoscopy has allowed TEP to continue evolving as the feasibility of this approach gains recognition as a preferable technique. Once considered very difficult to learn, TEP currently is adequately taught in many surgical training programs. This report reviews the fundamentals and details various modifications that make this procedure more desirable than open procedures and other laparoscopic techniques. A resultant decrease in operative time, cost of the procedure, and morbidity to the patient is routine. In addition, the authors review their institutional experience and examine other current evidence-based data.

BACKGROUND: One of today's most highly regarded procedures for treating inguinal hernia is the totally extraperitoneal approach (TEP), but it can on occasion lead to recurrence. This is commonly managed with an open repair, a transabdominal preperitoneal procedure (TAPP), or another TEP. We report here on our years of experience with the latter. METHODS: The endeavor to a secondary TEP is much the same as to a primary one, but certain differences are encountered as the operation proceeds. For example, many anatomical landmarks found in a first TEP cannot be seen in a second. There can also be a diminished amount of working space, and this occasionally leads to an open conversion. RESULTS: From September 1991 to September 2005, we repaired 1,526 hernias in 1,156 male patients, using the TEP in every case. Of these, 21 were TEPs after a previous TEP. In 3 cases, the space could not be opened, and they were converted to the open Lichtenstein. One patient had peritoneal tears that led to conversion and another had conversion because of excessive bleeding. There were no complications, no bladder or bowel injuries, no transfusions, no preperitoneal hematomas, and no fatalities. All patients were discharged the same day. CONCLUSIONS: A secondary TEP, open repair, and TAPP are alternative solutions to the problem of recurrence after TEP. However, any TEP involves a very prolonged learning curve for general surgeons, since they must learn the anatomy as well as the procedure, both at the same time. This is doubly true for the TEP after a previous TEP.

BACKGROUND: Large-core biopsies or open biopsies with needle localization have been the mainstay of treatment for evaluating nonpalpable mammographic abnormalities. The newly introduced Advanced Breast Biopsy Instrumentation (ABBI) system combines digital stereotactic imaging with a highly developed single-use biopsy device to locate and remove a radiographically discovered breast lesion to an accuracy of 1 mm. STUDY DESIGN: We conducted a review of the first 58 cases involving the use of the ABBI system. This article evaluates the accuracy of specimen targeting, the success rate of lesion removal, the operative complications, the mechanical difficulties, and patient satisfaction with the ABBI system. RESULTS: The lesion was removed successfully in 47 of the 58 cases. Nine patients were eliminated in initial screening and the procedure could not be completed in two. Although the success rate was high, 14 of the procedures required conversion to "open" ABBI procedures for completion of the biopsy. CONCLUSIONS: The ABBI system is an alternative to open biopsy with needle localization or large-core biopsy for nonpalpable mammographic abnormalities. This technique allows complete removal of the lesion in a one-step procedure. The ABBI system has certain limitations and mechanical problems, at least currently, and offers an advantage over current diagnostic modalities in a very limited number of cases only.

BACKGROUND: In 1975, researchers introduced the use of a large unsutured polyester mesh prosthesis placed in the preperitoneal space for inguinal hernia repair. Different stapling devices have been used to secure this mesh, and the most common complication of the procedure is nerve damage secondary to the staples. The necessity of stapling has never been demonstrated. We designed a prospective randomized study of the need for stapling in laparoscopic extraperitoneal repair of inguinal hernias with 1-year and 3-year followup. STUDY DESIGN: Inclusion criteria of the study were men older than 18 years and first-time inguinal hernia repair. Patients with recurrence and previous abdominal operations were excluded to avoid confounding variables. Each patient's hernia was assigned a consecutive random number chosen by computer, with each number corresponding to an assigned group. The first group had stapled mesh and the second had unstapled mesh. RESULTS: Data were collected over a 15-month period, with each procedure having a mean followup time of 8 months. A total of 100 procedures was performed in 92 patients. The two groups of patients were well matched for age and the type of hernia repaired. There were no recurrences in either group and no complications or deaths. CONCLUSIONS: The initial 12-month followup showed no significant differences in recurrence or complication rates between the stapled and unstapled groups. Both groups returned to work within an average of 4 days. A net savings of $120 was realized for each hernia repair performed without stapled mesh. In addition, stapling presents an inherent risk of nerve damage.

BACKGROUND: The Lap-Band is a gastric restrictive procedure for the treatment of morbid obesity. We review the etiology of obstructive complications that present in the first postoperative 24 h. METHODS: Fifty-six Lap-Band procedures were performed by one surgeon between January and September 2002. RESULTS: Six patients presented with obstruction within 24 h of surgery: gastric slippage in three patients, gastric edema in one patient, and esophageal hypomotility in two patients. CONCLUSIONS: Placing the band in an esophagogastric position as per Belachew and Weiner reduced our incidence of gastric slippage to none. Endoscopy with placement of a nasogastric feeding tube can relieve obstruction caused by esophageal hypomotility. Gastric edema with no clinical signs of obstruction will resolve with time. Clinicians must be aware of the unique complications that come with the advent of this new procedure.

BACKGROUND: In recent years, autopsy consent rates have fallen nationwide. In our institution they have declined from 15% to 7% in 10 years. We perceived that family reluctance to grant permission for autopsy was related to the invasiveness of the open procedure, so we began to do autopsies by needle biopsy, with an increase in consents to 25% during the first year. However, the procedure is inherently inaccurate, so we recently have introduced minimally invasive laparoscopic autopsy. METHODS: From July through October 1999, needle biopsy was performed on 25 patients who died at our institution, which was followed by laparoscopic evaluation. Consent for full conventional autopsy had been granted in nine cases, and these then were performed. Data from these autopsies were compared with those from the laparoscopic procedures. RESULTS: Of the patients for whom consent was obtained for open autopsy, there was complete agreement as to cause of death between the laparoscopic and conventional procedures. In one case, a liver hemangioma was missed by laparoscopy, and in two other cases, colon polyps were not discovered. Biopsies of internal organs were accurately performed on the pancreas, kidneys, and adrenals, all of which had been troublesome for needle biopsy alone. CONCLUSIONS: Laparoscopic autopsy is much more acceptable to the families of patients than the conventional form, resulting in a higher consent rate. On the basis of our study group, this procedure provides accurate data concerning the cause of death. In addition, performing these autopsies gives surgical residents invaluable training in laparoscopic skills.

BACKGROUND: There are only scant published reports of totally extraperitoneal (TEP) repair of recurrence after a primary TEP procedure. Furthermore, at least two authors have made the statement that such an operation is virtually impossible. METHODS: We have been performing TEP repair of recurrence after TEP since we 1996, and here we present a retrospective review of our experience with the procedure. We employ a method not varying greatly from the standard TEP done for primary hernia. RESULTS: All cases were started laparoscopically, and only one of 20 had to be converted to open. Of these cases, 12 were for same-side recurrence and eight for a contralateral new hernia. With a follow-up of 28-74 months, there have been no fatalities, no complications, and no re-recurrence. CONCLUSION: We have found that TEP repair of recurrent inguinal hernia after a primary TEP repair is entirely feasible technically as well as entirely safe.

BACKGROUND: Delay in the diagnosis of intraabdominal pathology is a major contributor to the morbidity and mortality of intensive care unit (ICU) patients. Laparoscopy is a valuable diagnostic tool that can be used safely and efficiently in the evaluation of intraabdominal processes that may be difficult to diagnose with conventional methods. Our goal was to show that laparoscopy performed at the bedside in the ICU could be used as a routine diagnostic tool in the evaluation of critically ill patients, just as computed tomography (CT), ultrasonography (US), and radiography are. METHODS: We present 11 patients who underwent 12 bedside examinations in the ICU of a community teaching hospital. Several different surgeons with varying degrees of laparoscopic experience performed these procedures over a 1-year period. RESULTS: Four patients had previously undergone recent abdominal operations. Nontherapeutic laparotomy was avoided in six patients because of diagnostic laparoscopy. One patient also underwent a therapeutic maneuver at the time of diagnostic laparoscopy. None of the patients required general anesthesia, although local anesthetics and sedation with midazolam or propofol were used. One patient underwent the procedure without endotracheal intubation. There were no complications or mortalities directly related to the procedure. CONCLUSION: We conclude that bedside laparoscopy in the ICU under local anesthesia is a diagnostic and potentially therapeutic tool that can be used safely in the work-up of potential abdominal pathology in critically ill patients.

One hundred twenty-two hernias were repaired in 101 male patients through a total extraperitoneal approach. Patients ranged from 18 to 78 years old. All repairs were done with polypropylene mesh. Five patients (5%) required conversion to an open or transabdominal approach. Patients have been followed from 6 to 20 months, with a mean of 12 months. No recurrence has developed to date. Complications included urinary retention, groin hematoma, trocar site infection, and lateral femoral cutaneous nerve neuralgia. Six patients underwent simultaneous extraperitoneal endoscopic pelvic lymph node dissections, and two patients had varicoceles repaired simultaneously. Patients returned to usual activity within 1 week.

Resident competence in both open and laparoscopic cholecystectomy (LC) has been a concern among general surgeons. Laparoscopic surgery was late in coming at many surgical residency programs in the United States, and many residents have graduated with limited experience in LC. We are chief residents who were fortunate enough to start our training when LC was first introduced at our institution in 1990. This report summarizes our experience with LC in our chief year, during which we performed LC on 147 patients. The average operating time was 37 minutes (range, 12-82 minutes). Six patients (4%) required conversion to an open procedure. There were three complications (2 postoperative cystic duct leaks and 1 intraoperative common bile duct injury) for an overall complication rate of 2%. There was no mortality. It is our conclusion that graduating chief residents with 5 years' exposure to LC may perform the procedure with a complication rate comparable to that reported in the current literature. Insuring that graduating chief residents have adequate training in open cholecystectomy may become a more pressing issue in the near future.

The objective of this study was to determine whether extraperitoneal lymph node dissection for the staging of prostate cancer and extraperitoneal herniorrhaphy could be performed concomitantly with acceptable operative time and morbidity. Sixty patients underwent endoscopic extraperitoneal lymph node dissection (EEPLND) between 1991 and 1996. Eleven of these had 14 hernias repaired with polypropylene mesh. Endoscopic hernia repair added an average of 15 to 20 minutes to the EEPLND, resulting in an average operative time of 127 minutes (range 90 to 182 minutes). There was no difference in postoperative pain between patients undergoing combined operations and those undergoing EEPLND alone. The mean hospital stay after either procedure was 48 hours. There were no complications in the group undergoing herniorrhaphy. We conclude that extraperitoneal endoscopic hernia repair can be safely performed with EEPLND when necessary.

BACKGROUND: Laparoscopic repair of scrotal hernias is often a difficult endeavor to successfully complete. The longstanding nature of these hernias often results in significant adhesions and anatomic distortion of the inguinal floor. These two issues make reduction of the hernia arduous and subsequent reinforcement of the parietal sac difficult. We have previously described techniques to increase the chances of success when attempting laparoscopic repair of scrotal hernias. Here, we describe some of those techniques as well as a combined laparoscopic and open approach to achieve a robust preperitoneal repair of incarcerated scrotal hernias when the usual totally extraperitoneal approach does not work. PATIENTS AND METHODS: We performed a retrospective review of 1890 TEP hernia repairs we performed from 1990 to 2010. Rate of conversion to an open approach or a combined laparoscopic and open approach was examined. Incidence of complications or recurrences was assessed over a 12-month follow-up period. RESULTS: Among the 1890 TEP repairs, 94 large scrotal hernias were identified. Of these, nine cases (9.5 %) required conversion to an open procedure due to an incarcerated and indurated omentum. Three were completed with a conventional open preperitoneal whereas six patients (6.4 %) underwent repair with the combined approach. In this group, no recurrences or complications were found over a 12-month period. CONCLUSION: In cases where a large scrotal hernia may be difficult or dangerous to reduce laparoscopically, immediate conversion to an open repair may not be necessary. A combined laparoscopic and open approach can greatly assist in the visualization and dissection of the preperitoneal space, thereby facilitating reduction of the hernia and placement of the mesh.
