Single-incision laparoscopic cholecystectomy using a modified dome-down approach with conventional laparoscopic instruments.

INTRODUCTION: Single-incision laparoscopic cholecystectomy (SILC) may increase the risk of bile duct injury due to compromised operative exposure. Dome-down laparoscopic cholecystectomy provides the ability to evaluate the cystic duct circumferentially prior to its division, thus minimizing the risks of bile duct injury. This study assesses the feasibility and safety of SILC using a modified dome-down approach with all conventional laparoscopic instruments. METHODS: Three low-profile 5-mm trocars are placed via a single transumbilical incision. The two working trocars are aimed laterally via the rectus to achieve adequate triangulation. An extralong 5-mm 30º laparoscope with an L-shaped light-cord adaptor is used to yield more external working space. Cephalic liver retraction is achieved with one transabdominal suture through the gallbladder fundus. Leaving the gallbladder fundus attached to the liver bed, a window is first created between the gallbladder body and the liver. The dissection is then carried down retrograde toward the porta hepatis. A 360º view of the gallbladder-cystic duct junction is achieved prior to transecting the cystic duct. The gallbladder is then freed by separation of the fundal attachments. The specimen is retrieved by enlarging the fascial incision. All fascial defects are then primarily closed. RESULTS: Sixteen patients (mean age 31 years, mean BMI 26.3 kg/m(2)) were enrolled in this study. Thirteen had elective surgery for symptomatic cholelithiasis, and three had emergency surgery for acute cholecystitis. Mean operating time was 80.3 min, and blood loss was minimal. All patients were discharged within 24 h without complications. Follow-up at 1 month revealed a barely visible scar within the umbilicus. CONCLUSIONS: SILC using a modified dome-down approach is technically feasible with all straight instruments, and it is safe because of good delineation of ductal anatomy. Adoption of this approach may minimize the risk of bile duct injury during early experience of SILC.

Laparoscopic cholecystectomy.

Laparoscopic cholecystectomy (LC) has supplanted open cholecystectomy for most gallbladder pathology. Experience has allowed the development of now well-established technical nuances, and training has raised the level of performance so that safe LC is possible. If safe cholecystectomy cannot be performed because of acute inflammation, LC tube placement should occur. A systematic approach in every case to open a window beyond the triangle of Calot, well up onto the liver bed, is essential for the safe completion of the operation.

Metabolic characterization of nondiabetic severely obese patients undergoing Roux-en-Y gastric bypass: preoperative classification predicts the effects of gastric bypass on insulin-glucose homeostasis.

INTRODUCTION: Obese individuals may have normal insulin-glucose homeostasis, insulin resistance, or diabetes mellitus. Whereas gastric bypass cures insulin resistance and diabetes mellitus, its effects on normal physiology have not been described. We studied insulin resistance and beta-cell function for patients undergoing gastric bypass. METHODS: One hundred thirty-eight patients undergoing gastric bypass had fasting insulin and glucose levels drawn on days 0, 12, 40, 180, and 365. Thirty-one (22%) patients with diabetes mellitus were excluded from this analysis. Homeostatic model of assessment was used to estimate insulin resistance, insulin sensitivity, and beta-cell function. Based on this model, patients were categorized as high insulin resistance if their insulin resistance was >2.3. RESULTS: Body mass index did not correlate with insulin resistance. Forty-seven (34%) patients were categorized as high insulin resistance. Correction of insulin resistance for this group occurred by 12 days postoperatively. Sixty (43%) patients were categorized as low insulin resistance. They demonstrated an increase of beta-cell function by 12 days postoperatively, which returned to baseline by 6 months. At 1 year postoperatively, the low insulin resistance group had significantly higher beta-cell function per degree of insulin sensitivity. CONCLUSIONS: Adipose mass alone cannot explain insulin resistance. Severely obese individuals can be categorized by degree of insulin resistance, and the effect of gastric bypass depends upon this preoperative physiology.

Optimizing laparoscopic task efficiency: the role of camera and monitor positions.

BACKGROUND: Alterations of video monitor and laparoscopic camera position may create perceptual distortion of the operative field, possibly leading to decreased laparoscopic efficiency. We aimed to determine the influence of monitor/camera position on the laparoscopic performance of surgeons of varying skill levels. METHODS: Twelve experienced and 12 novice participants performed a one-handed task with their dominant hand in a modified laparoscopic trainer. Initially, the camera was fixed directly in front of the participant (0 degrees) and the monitor location was varied between three positions, to the left of midline (120 degrees), directly across from the participant (180 degrees), and to the right of the midline (240 degrees). In the second experiment monitor position was constant straight across from the participant (180 degrees) while the camera position was adjusted between the center position (0 degrees), to the left of midline (60 degrees), and to the right of midline (300 degrees). Participants completed five trials in each monitor/camera setting. The significance of the effects of skill level and combinations of camera and monitor angle were evaluated by analysis of variance (ANOVA) for repeated measures using restricted maximum likelihood estimation. RESULTS: Experienced surgeons completed the task significantly faster at all monitor/camera positions. The best performance in both groups was observed when the monitor and camera were located at 180 degrees and 0 degrees, respectively. Monitor positioning to the right of midline (240 degrees) resulted in significantly worse performance compared to 180 degrees for both experienced and novice surgeons. Compared to 0 degrees (center), camera position to the left or the right resulted in significantly prolonged task times for both groups. Novice subjects also demonstrated a significantly lower ability to adjust to suboptimal camera/monitor positions. CONCLUSION: Experienced subjects demonstrated superior performance under all study conditions. Optimally, the camera should be directly in front and the monitor should be directly across from a surgeon. Alternatively, the monitor/camera could be placed opposite to the surgeon's non-dominant hand. The suboptimal camera/monitor conditions are especially difficult to overcome for inexperienced subjects. Monitor and camera positioning must be emphasized to ensure optimal laparoscopic performance.

Immunologic effects of hand-assisted surgery on peritoneal macrophages: comparison to open and standard laparoscopic approaches.

BACKGROUND: Exaggerated activation of peritoneal immunity after major abdominal surgery activates peritoneal macrophages (PMs), which may lead to a relative local immunosuppression. Although laparoscopy (L) is known to elicit a smaller attenuation of peritoneal host defenses, compared with open (O) surgery, effects of the hand-assisted (HA) approach have not been investigated to date. METHODS: Eighteen pigs underwent a transabdominal nephrectomy via O, HA, or L approach. PMs were harvested at 4, 12, and 24 hours through an intraperitoneal drain and stimulated in vitro with lipopolysaccharide. The production of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) by the purified macrophage cultures was measured with the use of a standard enzyme-linked immunosorbent assay technique. Statistical comparison was performed by using analysis of variance and Student t test. RESULTS: In vitro lipopolysaccharide-induced IL-6 and TNF-alpha production by PMs increased over the 24-hour period in all 3 groups. Stimulated PMs harvested at 12 and 24 hours postoperatively secreted higher levels of IL-6 in the O group, compared with both the HA group (P = .02, P = .01) and L group (P = .04, P = .001). PMs harvested at 4, 12 and 24 hours postoperatively also produced more TNF-alpha in O group, compared with both the HA group (P = .03, P = .03, and P = .01) and L group (P = .01, P = .05 and P = .03). There was no significant difference between H and L groups in production of either cytokine. CONCLUSIONS: Abdominal surgery attenuates peritoneal host defenses regardless of the surgical approach employed. However, for the first time, we demonstrated that the HA approach, similar to laparoscopy, is superior to open surgery in the degree of PM activation. Overall, in addition to clinical benefits of minimal access, HA surgery may confer an immunologic advantage over laparotomy.

Benefits of laparoscopic adrenalectomy: a 10-year single institution experience.

INTRODUCTION: We aimed to compare the outcomes of laparoscopic and open adrenalectomies and to assess the impact of the availability of advanced laparoscopy on adrenal surgery at our institution. MATERIALS AND METHODS: A retrospective analysis of data of all patients who underwent adrenalectomy at the University of Massachusetts Medical Center over a 10-year period. RESULTS: Sixty-four consecutive patients underwent adrenalectomy during the study periods. There were 19 open (OA) and 45 laparoscopic (LA) adrenalectomies performed. There was no significant difference between the average size of adrenal masses removed for the LA and the OA groups [4.3 vs. 5.5 cm, respectively (P=0.23)]. LA proved superior to OA, resulting in shorter operative times (171 vs. 229 min, P=0.02), less blood loss (96 vs. 371 mL, P<0.01), shorter time to regular diet (1.9 vs. 4.4 d, P<0.001), and shorter hospital stay (2.5 vs. 5.8 d, P=0.02). In addition, the average annual number of adrenalectomies increased significantly since the establishment of our advanced laparoscopic program (10.0 vs. 2.0, P=0.02). CONCLUSIONS: LA offers superior results when compared to OA in terms of operative time, blood loss, return of bowel function, duration of hospital stay, and functional recovery. The availability of advanced laparoscopy has resulted in a significant increase in the number of adrenalectomies performed at our institution without a shift in surgical indications.

Cholecystostomy Treatment in an ICU Population: Complications and Risks.

BACKGROUND: Percutaneous cholecystostomy tube placement has widely been used as an alternative treatment to cholecystectomy, especially in advanced disease or critically ill patients. Reported postprocedural complication rates have varied significantly over the last decade. The goal of this study is to evaluate the safety of percutaneous cholecystostomy tube treatment in critically ill patients. STUDY DESIGN: We performed a retrospective chart analysis of 96 critically ill patients who underwent cholecystostomy tube placement during an intensive care unit (ICU) stay between 2005 and 2010 in a tertiary care center in central Massachusetts. Complications within 72 hours of cholecystostomy tube placement and any morbidity or mortality relating to presence of cholecystostomy tube were considered. RESULTS: A total of 65 male and 31 female patients with a mean age of 67.4 years underwent percutaneous cholecystostomy tube placement during an ICU stay. Sixty-six patients experienced a total of 121 complications, resulting in an overall complication rate of 69%. Fifty-four of these complications resulted from the actual procedure or the presence of the cholecystostomy tube; the other 67 complications occurred within 72 hours of the cholecystostomy procedure. Ten patients died. Tube dislodgment was the most common complication with a total of 34 episodes. CONCLUSIONS: Cholecystostomy tube placement is associated with frequent complications, the most common of which is tube dislodgment. Severe complications may contribute to serious morbidity and death in an ICU population. Complication rates may be underreported in the medical literature. The potential impact of cholecystostomy tube placement in critically ill patients should not be underestimated.

Advantages of mini-laparoscopic vs conventional laparoscopic cholecystectomy: results of a prospective randomized trial.

HYPOTHESIS: The use of smaller instruments during laparoscopic cholecystectomy (LC) has been proposed to reduce postoperative pain and improve cosmesis. However, despite several recent trials, the effects of the use of miniaturized instruments for LC are not well established. We hypothesized that LC using miniports (M-LC) is safe and produces less incisional pain and better cosmetic results than LC performed conventionally (C-LC). DESIGN: A patient- and observer-blinded, randomized, prospective clinical trial. SETTING: A tertiary care, university-based hospital. PATIENTS: Seventy-nine patients scheduled for an elective LC who agreed to participate in this trial were randomized to undergo surgery using 1 of the 2 instrument sets. The criteria for exclusion were American Society of Anesthesiologists class III or IV, age older than 70 years, liver or coagulation disorders, previous major abdominal surgical procedures, and acute cholecystitis or acute choledocholithiasis. INTERVENTION: Laparoscopic cholecystectomy performed with either conventional or miniaturized instruments. MAIN OUTCOME MEASURES: Patients' age, sex, operative time, operative blood loss, intraoperative complications, early and late postoperative incisional pain, and cosmetic results. RESULTS: Thirty-three C-LCs and 34 M-LCs were performed and analyzed. There were 8 conversions (24%) to the standard technique in the M-LC group. No intraoperative or major postoperative complications occurred in either group. The average incisional pain score on the first postoperative day was significantly less in the M-LC group (3.9 vs 4.9; P = .04). No significant differences occurred in the mean scores for pain on postoperative days 3, 7, and 28. However, 90% of patients in the M-LC group and only 74% of patients in the C-LC group had no pain (visual analog scale score of 0) at 28 days postoperatively (P = .05). Cosmetic results were superior in the M-LC group according to both the study nurse's and the patients' assessments (38.9 vs 28.9; P<.001, and 38.8 vs 33.4; P = .001, respectively). CONCLUSIONS: Laparoscopic cholecystectomy can be safely performed using 10-mm umbilical, 5-mm epigastric, 2-mm subcostal, and 2-mm lateral ports. The use of mini-laparoscopic techniques resulted in decreased early postoperative incisional pain, avoided late incisional discomfort, and produced superior cosmetic results. Although improved instrument durability and better optics are needed for widespread use of miniport techniques, this approach can be routinely offered to many properly selected patients undergoing elective LC.

Predictors of complication and suboptimal weight loss after laparoscopic Roux-en-Y gastric bypass: a series of 188 patients.

HYPOTHESIS: An analysis of patients undergoing laparoscopic Roux-en-Y gastric bypass (RYGB) may identify factors predictive of complication and of suboptimal weight loss. DESIGN: Inception cohort. SETTING: Metropolitan university hospital. PATIENTS: One hundred eighty-eight consecutive patients with severe obesity who met National Institutes of Health consensus guidelines for bariatric surgery. INTERVENTIONS: Laparoscopic RYGB. MAIN OUTCOME MEASURES: Complications requiring therapeutic intervention and percentage of excess body weight lost at 1 year after surgery. RESULTS: Of the 188 patients who underwent laparoscopic RYGB, 50 (26.6%) developed complications that required an invasive therapeutic intervention, including 2 deaths. The average follow-up was 351 days (range, 89-1019 days). Multivariate analysis by stepwise logistic regression identified surgeon experience, sleep apnea (P =.003; odds ratio, 3.0; 95% confidence interval, 1.3-7.1), and hypertension (P =.07; odds ratio, 2.0; 95% confidence interval, 1.0-4.0) as predictors of complications. The most common complication requiring therapeutic intervention was stricture at the gastrojejunal anastomosis, occurring in 27 patients (14.4%). Of the 115 patients who underwent surgery more than 1 year previously, 1-year follow-up data were available for 93 (81%). The body mass index (weight in kilograms divided by the square of height in meters) decreased from 53 +/- 8 preoperatively to 35 +/- 6 at 1 year. The mean +/- SD percentage of excess body weight lost at 1 year was 61% +/- 14%. Diabetes mellitus was negatively correlated with percentage of excess body weight lost at 1 year (P =.06). CONCLUSIONS: Surgeon experience, sleep apnea, and hypertension are associated with complications after laparoscopic RYGB. Diabetes mellitus may be associated with poorer postoperative weight loss.

Is the use of a bougie necessary for laparoscopic Nissen fundoplication?

HYPOTHESIS: Esophageal intubation with a bougie during laparoscopic Nissen fundoplication (LNF) is commonly used to prevent an excessively tight wrap. However, a bougie may cause intraoperative gastric and esophageal perforations. We hypothesized that LNF is safe and effective when performed without a bougie. DESIGN: Retrospective review of 102 consecutive patients who underwent LNF without a bougie. SETTING: Tertiary care university hospital. PATIENTS: All patients presented with symptoms of reflux disease. Mean (+/- SD) percentage of time with pH of less than 4 was 12.6% +/- 9.4%. Mean DeMeester score was 47.8. Mean (+/- SD) resting lower esophageal sphincter pressure was 15.0 +/- 9.4 mm Hg. Mean (+/- SD) distal esophageal amplitude was 69.4 +/- 39.2 mm Hg. INTERVENTION: During LNF, we obtained 2 to 3 cm of intra-abdominal esophagus, divided all short gastric vessels, reapproximated the crura, and performed a loose 360 degrees fundoplication without a bougie. MAIN OUTCOME MEASURES: Postoperative rates of dysphagia, gas bloat, and recurrent reflux. RESULTS: In the early postoperative period, 50 patients (49.0%) complained of mild, 11 (10.8%) of moderate, and 7 (6.9%) of severe dysphagia. Average (+/- SD) duration of early dysphagia was 4.6 +/- 2.1 weeks. Dysphagia resolved in 61 (89.7%) of 68 patients within 6 weeks. Late resolution of dysphagia was noted in 4 (5.8%) patients. Three patients were successfully treated with esophageal dilatations. Persistent dysphagia was found in 1 patient. Thirty patients (29.4%) had transient gas bloat. Mild persistent reflux, requiring daily medication, was noted in 5 (4.9%) patients. CONCLUSIONS: Performance of LNF without a bougie offers a safe and effective therapy for gastroesophageal reflux disease. While avoiding the potential risks for gastric and esophageal injury, it may provide low rates of long-term postoperative dysphagia and reflux recurrence.

Watermelon stomach: pathophysiology, diagnosis, and management.

Watermelon Stomach (WS) has been increasingly recognized as an important cause of occult gastrointestinal blood loss. Clinically, patients develop significant iron deficiency anemia and are frequently transfusion dependent. The histologic hallmark of WS is superficial fibromuscular hyperplasia of gastric antral mucosa with capillary ectasia and microvascular thrombosis in the lamina propria. Endoscopic findings of the longitudinal antral folds containing visible columns of tortuous red ectatic vessels (watermelon stripes) are pathognomonic for WS. Trauma to the mucosal epithelium overlying engorged vessels by gastric acid or intraluminal food results in bleeding. Treatment options for WS include endoscopic, pharmacologic, and surgical approaches. Endoscopic therapy, including contact and non-contact thermal ablations of the angiodysplastic lesions, is the mainstay of conservative therapy. However, many patients fail endoscopic therapy and develop recurrent acute and chronic GI bleeding episodes. Surgical resection may be the only reliable method for achieving a cure and eliminating transfusion dependency. Traditionally, surgery was used only as a last resort after patients failed prolonged medical and/or endoscopic therapy. However, based on the experience garnered from the literature we recommend a more aggressive surgical approach in patients who fail a short trial of endoluminal therapy.

Hand-assisted laparoscopic aortobifemoral bypass versus open bypass for occlusive disease.

BACKGROUND: Aortobifemoral bypass grafting is the treatment of choice for patients with symptomatic aortoiliac occlusive disease. Yet, traditional operative exposure through a midline laparotomy incision carries significant morbidity. The authors compare operative and patient outcomes following hand-assisted laparoscopic aortobifemoral (HALABF) bypass and open aortobifemoral (OABF) bypass. METHODS: An initial series of patients who underwent HALABF bypass grafting (n = 8) were compared with a simultaneous cohort of patients treated with standard open bypass (n = 10). The two groups were similar with respect to age, weight, and sex. Operative parameters, clinical outcomes, and complications were compared. RESULTS: HALABF was successfully performed in all eight cases attempted. Operative times did not differ between the laparoscopic and open groups (234 +/- 42 minutes vs. 206 +/- 43 minutes, P =.99). Mean blood loss values were comparable (562 mL [HALABF] vs. 756 mL [OABF], P =.56). There were no conversions. Time to resumption of oral intake (1.8 vs. 4.7 days, P =.001) and length of stay (3.8 vs. 6.3 days, P =.0004) were significantly shorter in the laparoscopic than in the open group. CONCLUSIONS: HALABF is a safe and technically feasible procedure. When compared with the traditional open operation, this technique may result in shorter hospitalization, more rapid return of bowel function, and earlier return to activity.

Staple line bleeding following laparoscopic splenectomy: intraoperative prevention and postoperative management with splenic artery embolization.

Laparoscopic splenectomy (LS) has become the procedure of choice for a variety of hematologic disorders and non-traumatic splenic pathology. Perioperative hemorrhage remains one of the most feared complications. We report 2 cases of postoperative splenic artery hemorrhage following vascular division using 2.5-mm Endo-GIA stapling cartridges. In this paper we identify and discuss important technical aspects of obtaining hilar vascular control during LS and report the first use of postoperative splenic artery embolization to control staple line bleeding following LS.

Feasibility of laparoscopic adrenalectomy for large adrenal masses.

Laparoscopic adrenalectomy (LA) is a preferred method for the removal of small adrenal masses. However, the role of LA for surgical treatment of large adrenal masses is less established. We evaluated the outcomes of LA for large (>/=5 cm) adrenal masses. We retrospectively reviewed 24 consecutive patients who underwent LA for large adrenal masses at a tertiary care university hospital. The average age of the 24 patients was 49 years, and each underwent laparoscopic resection of a large adrenal mass. All LAs were performed via a lateral transperitoneal approach. The average (+/- standard deviation) size of the masses was 6.8 +/- 1.5 cm (range, 5-11). Pathologic diagnoses included adrenal cortical adenoma (10 cases), pheochromocytoma ( 7), cyst/pseudocyst ( 3), myolipoma ( 2), and adrenal cortical hyperplasia ( 2). Statistical analysis was performed with a two-sample t test. The average operating time was 178 +/- 55 minutes (range, 120-300), and average blood loss was 87 +/- 69 mL (range, 20-300); the averages were nonsignificantly greater in the right LA group than in the left LA group (203 vs. 166 minutes, P = 0.89; 124 vs. 77 mL, P = 0.14). The average duration of nothing-by-mouth (NPO) status was 0.7 days (range, 0-4), and the average time until return to a regular diet was 1.74 +/- 0.9 days (range, 1-5). The average length of stay was 2.5 +/- 1.9 days (range, 1-10). One patient had a transient episode of pseudomembranous colitis. There were no conversions to open adrenalectomy and no major morbidities or mortalities. LA is safe and effective for surgical treatment of large adrenal masses. Both right and left large adrenal masses can be approached laparoscopically with equal success. The role of minimally invasive approaches to adrenal malignancies necessitates further investigation.

Hand-assisted laparoscopic surgery.

The introduction of hand-assisted laparoscopic surgery (HALS) has occurred in several surgical specialties. It allows the laparoscopic surgeon to insert a hand into the peritoneal cavity, through a small incision, while maintaining pneumoperitoneum. This technique has been made possible through the engineering of several unique devices. By returning the hand to the peritoneal cavity, the surgeon is allowed the return of tactile sensation, atraumatic retraction, blunt dissection, and digital vascular control. Proper device placement is mandatory. The principles include port-site triangulation, conversion to a convenient open incision if necessary, location away from bony prominences, and placement to minimize hand fatigue. Application and advantages of HALS can be shown in several procedures; specifically, laparoscopic splenectomy in cases of splenomegaly, laparoscopic live-donor nephrectomy, and laparoscopic sigmoid colectomy for diverticular disease. Its use in these procedures does not appear to be detrimental to the benefits associated with a completely laparoscopic technique, and may offer advantages. It may alter the learning curve regarding advanced laparoscopic procedures for the neophyte laparoscopic surgeon, and allow them to perform operations they otherwise would not attempt. For the experienced laparoscopic surgeon, it may allow them to complete operations laparoscopically they might otherwise have to convert. In time, HALS may have a larger role in many advanced surgical procedures.

Hand-Assisted laparoscopic Surgery.

Hand-assisted laparoscopic surgery (HALS) has been sporadically described in the past to assist the surgeon during operations of complexity or when operations require specimen removal. The hand will offer the surgeon an advantage in terms of tactile feedback, exposure, retraction, or orientation so that it will enable him or her to operate with greater safety and efficiency. The fundamental pre-requisite for successful HALS is a reliable hand-assist device. We perform HALS for complex advanced laparoscopic surgery where it may save time, increase accuracy and improve safety. Additionally, this approach is considered for any operation that requires specimen removal, since an enlarged incision may be required. Early introduction of the hand may facilitate dissection and specimen removal.

New Device for Hand-Assisted Laparoscopic Surgery.

Laparoscopic surgery has undergone a rapid evolution since the first laparoscopic cholecystectomy of Erich Mühe in 1985. Many surgeons felt that further technological success would be related not only to increasing experience and skill of surgeons, but also technological advances which would enable surgeons to perform increasingly more difficult and complex tasks. Progress has been rapid for some, but broad acceptance by surgeons has been slow.

Timing and choice of intervention influences outcome in acute cholecystitis: a prospective study.

PURPOSE: Determine which management strategy is ideal for patients with acute cholecystitis. MATERIALS AND METHODS: Prospective enrollment between August 2009 and March 2011. Large academic center. Patients with acute cholecystitis. Laparoscopic cholecystectomy, intravenous antibiotics followed by laparoscopic cholecystectomy or percutaneous cholecystostomy. Primary endpoints were postoperative complications and 30-day mortality. RESULTS: A total of 162 patients were enrolled, 53 (33%) with simple acute cholecystitis and 109 (67%) with complex acute cholecystitis. Of the 109 patients with complex cholecystitis, 77 (70.6%) underwent successful laparoscopic cholecystectomy during the same hospital admission and 6 patients (5.5%) had an unsuccessful laparoscopic cholecystectomy requiring conversion to cholecystostomy. Radiology performed cholecystostomy in 19 (11.7%) patients with complex acute cholecystitis and 4 (2.5%) patients with simple acute cholecystitis for a total 23 patients of the 162 patients in the study. Nine of the 23 patients had dislodged tubes (39.1%). Two of the 23 patients (8.7%) had significant bile leaks resulting in either sepsis or emergency surgery. One patient (4.3%) had a wound infection. Overall, patients with complex acute cholecystitis had a higher morbidity rate (31.2%) compared with patients with simple acute cholecystitis (26.4%). CONCLUSIONS AND RELEVANCE: A high complication rate seen with radiology placed percutaneous cholecystostomy tubes prompted our center to reevaluate the treatment algorithm used to treat patients with complex acute cholecystitis. Although laparoscopic cholecystectomy is considered to be the gold standard in the treatment of acute cholecystitis, if laparoscopic cholecystectomy is not felt to be safe due to gallbladder wall thickening or symptoms of >72 hours' duration, we now encourage the use of intravenous antibiotics to "cool" patients down followed by interval laparoscopic cholecystectomy approximately 6 to 8 weeks later. Patients who do not respond to antibiotics should undergo attempted laparoscopic cholecystectomy and if unable to be performed safely, a laparoscopic cholecystostomy tube can be placed under direct visualization for decompression followed by interval laparoscopic cholecystectomy at a later date.

Use of cholecystostomy tubes in the management of patients with primary diagnosis of acute cholecystitis.

BACKGROUND: Management of patients with severe acute cholecystitis (AC) remains controversial. In settings where laparoscopic cholecystectomy (LC) can be technically challenging or medical risks are exceedingly high, surgeons can choose between different options, including LC conversion to open cholecystectomy or surgical cholecystostomy tube (CCT) placement, or initial percutaneous CCT. We reviewed our experience treating complicated AC with CCT at a tertiary-care academic medical center. STUDY DESIGN: All adult patients (n = 185) admitted with a primary diagnosis of AC and who received CCT from 2002 to 2010 were identified retrospectively through billing and diagnosis codes. RESULTS: Mean patient age was 71 years and 80% had ≥1 comorbidity (mean 2.6). Seventy-eight percent of CCTs were percutaneous CCT placement and 22% were surgical CCT placement. Median length of stay from CCT insertion to discharge was 4 days. The majority (57%) of patients eventually underwent cholecystectomy performed by 20 different surgeons in a median of 63 days post-CCT (range 3 to 1,055 days); of these, 86% underwent LC and 13% underwent open conversion or open cholecystectomy. In the radiology and surgical group, 50% and 80% underwent subsequent cholecystectomy, respectively, at a median of 63 and 60 days post-CCT. Whether surgical or percutaneous CCT placement, approximately the same proportion of patients (85% to 86%) underwent LC as definitive treatment. CONCLUSIONS: This 9-year experience shows that use of CCT in complicated AC can be a desirable alternative to open cholecystectomy that allows most patients to subsequently undergo LC. Additional studies are underway to determine the differences in cost, training paradigms, and quality of life in this increasingly high-risk surgical population.

Athletic pubalgia (sports hernia).

Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome.
