Laparoscopic appendectomy by ultrasonically activated scalpel in acute appendicitis: preliminary report

BACKGROUND AND PURPOSE: Laparoscopic appendectomy (LA) is increasingly being used in treating acute appendicitis. New instruments such as the ultrasonically activated scalpel (UAS) have been introduced for most laparoscopic procedures. We evaluated the use of UAS in the performance of LA, as the potential of this instrument in this type of surgery remains to be defined. PATIENTS AND METHODS: Three patients with acute right lower abdominal pain were managed by the laparoscopic approach. Once the diagnosis of acute appendicitis was established, laparoscopic appendectomy was performed with the UAS. RESULTS: The mean operative time was 42.3 minutes (range 32-49 minutes). There were no complications related to the treatment with UAS of either the vascular pedicle or the appendicecal stump. No electrosurgical coagulation, clips, loops, or endostapler was used in any patient. CONCLUSIONS: Total LA performed with UAS is feasible. Use of the UAS may make dissection and resection of the appendix easier, helping to reduce the mean operative time.

Laparoscopic appendectomy using the LigaSure Vessel Sealing System

BACKGROUND: Laparoscopic appendectomy is increasingly being employed to treat acute appendicitis. The aim of the present study was to evaluate the efficacy and safety of the LigaSure Vessel Sealing System (Valleylab, Boulder, CO) in laparoscopic appendectomy. PATIENTS AND METHODS: Laparoscopic appendectomy was performed using the LigaSure system in 15 patients who had a preoperative diagnosis of acute appendicitis. RESULTS: In two patients, the operation was converted to open appendectomy. The mean operative time was 47 minutes (range, 22-120 minutes). There was no evidence of any complications related to the use of the LigaSure system. Neither surgical endoclips nor an endostapler were used in any patient. CONCLUSION: Laparoscopic appendectomy using the LigaSure system is a safe and efficient procedure for acute appendicitis. Use of the LigaSure system in laparoscopic appendectomy may simplify the operative procedure and reduce the operative time.     

Appendicectomy: laparoscopic or ''open approach''?

AIM: The aim of our study was to evaluate the advantages and disadvantages of open appendectomy versus laparoscopic appendectomy in the surgical treatment of acute appendicitis. We have compared the following items: operating time, postoperative pain, length of hospital stay, postoperative complications and costs. METHODS: The study was conducted on 435 patients admitted in our Department from December 1993 to December 2003 with diagnosis of acute appendicitis: 339 (77.9%) cases were operated with laparoscopic approach (LA group) and 96 (22.1%) cases with open approach (OA group) according to personal experience of surgeons on laparoscopic technique and patient's anthropometrical conformation. RESULTS: Mean operative time in LA group was 50 minutes (range 25-195) and 65 minutes (range 35-160) for OA group. In 15 patients (4.4%), the operation had to be converted to open approach. The morbidity was observed in 4.4% of patients for the LA group and 14.6% for the OA group. Hospital stay was faster for patients having laparoscopic appendectomy (2.5 days vs 3.5 days). Pain in the 1st and 2nd postoperative days, evaluated on the use of pain medication, was less in patient in LA group whereas the costs were higher in the LA group than in OA group. CONCLUSIONS: In our experience the laparoscopic approach to acute appendicitis can be considered safe and effective with diagnostic and therapeutic value. It significantly offers all the advantages of mini-invasive surgery reported in literature.     

Comparison of laparoscopic, open, and converted appendectomy for perforated appendicitis

BACKGROUND: Perforated appendicitis is associated with a significant risk of postoperative abdominal and wound infection. Only a few controversial studies evaluate the role of laparoscopy in perforated appendicitis. The significance of conversion from laparoscopy to open appendectomy for perforated appendicitis is not well defined. Statistical analysis was performed using Student's t-test. METHODS: Data on 52 patients with perforated appendicitis were prospectively collected and retrospectively reviewed. Among these patients, 18 had laparoscopic appendectomies (LA); 24 had open appendectomies (OA); and 10 had converted appendectomies (CA). The indications for either method were based on the attending surgeons's philosophy. Laparoscopic appendectomy was performed using a retrograde stapler technique. Operative time, hospital stay, ability to tolerate a liquid diet, and postoperative infectious complications were documented. RESULTS: No statistically significant difference in the operative time in minutes was found between the LA (114 +/- 29.3), CA (120.0 +/- 32.2), and OA (105.8 +/- 64.1) groups (p = NS). There was no statistically significance difference in length of stay (days) between the LA (9.2 +/- 4.1), OA (10.5 +/- 3.3), and CA (10.0 +/- 1.8) groups. The wound infection rate was less frequent in the LA group (0%) than in 0A (14%) and CA (10%) groups. The rate of intra-abdominal abscess infections (IAAs) and ileus were 22% and 28%, respectively, in LA group, 38% and 29%, respectively, in OA group, and 60% and 50%, respectively, in CA group. CONCLUSIONS: No difference in the rate of postoperative intra-abdominal abscesses exists between laparoscopic and open appendectomy for perforated appendicitis. Wound infections and ileus complicate the postoperative course of patients after laparoscopic appendectomy less frequently than after open appendectomy. The conversion of laparoscopic to open appendectomy for perforated appendicitis is associated with increased postoperative morbidity.

Laparoscopic appendectomy in pregnancy

BACKGROUND: Laparoscopic appendectomy (LA) is a safe, effective, and beneficial procedure for the treatment of acute appendicitis. However, limited data are available regarding the safety and feasibility of LA during pregnancy. METHODS: Between January 2001 and August 2004, 1235 patients with clinically suspected appendicitis underwent laparoscopic surgery at our hospital. Eleven patients (0.9%) were pregnant women (mean age, 25 years; age range, 19-37 years; range of gestational age, 4-30 weeks). Clinical data collected retrospectively included demographic information; preoperative, procedural, and postoperative information; and outcome of the pregnancy. RESULTS: All 11 pregnant women underwent laparoscopic surgery without need of conversion. Ten patients underwent LA and were found to have acute appendicitis on histologic analysis. One patient had torsion of the right fallopian tube and a healthy-looking appendix; she underwent detorsion of the fallopian tube and incidental appendectomy. Mean operative time was 50.5 minutes (range, 20-135 minutes). Length of postoperative hospital stay averaged 4.2 days (range, 1-11 days). One patient had a surgical wound infection, which was managed conservatively. Mean follow-up period was 14 months (range, 2-46 months). Seven pregnant women delivered healthy term infants, 2 had planned abortions, and 1 experienced fetal loss due to uterine infection and premature contractions 1 month after LA. Another patient had normal results at prenatal examination. CONCLUSION: Our data support the accumulating evidence that LA is a safe and feasible procedure for the treatment of acute appendicitis in all trimesters of pregnancy. Close maternal and fetal monitoring is essential during and after the operation.     

A comparative study of routine laparoscopic versus open appendectomy.

OBJECTIVE: We evaluated the outcomes of routine laparoscopy and laparoscopic appendectomy (LA) in patients with suspected appendicitis. This is a retrospective study of the outcomes of patients undergoing laparoscopic appendectomy compared with outcomes for patients undergoing open appendectomy (OA) during the time that LA came into use. METHOD: Results of patients managed with routine laparoscopy and LA for suspected acute appendicitis were reviewed and analyzed. The preoperative and intraoperative findings were recorded. The clinical outcomes were compared with those of patients undergoing OA in the preceding 10 months. RESULTS: During the LA study period, 97 patients (47 men) with the median age of 34 years (range, 18 to 79) presented with clinical features of acute appendicitis. With the exclusion of 5 patients with open operations and 10 patients with other pathologies, 82 patients underwent laparoscopic appendectomy (Group A) for appendicitis. Thirty-one (37.8%) patients had complicated appendicitis (perforated or gangrenous appendicitis). Conversions were required in 6 patients (7.3%). During the OA period, 125 patients (57 men) with the median age of 42 (range, 19 to 79) years were operated on. With the exclusion of 6 patients with other pathologies, 119 underwent OA for acute appendicitis (Group B). Fifty-one (42.9%) had either perforated or gangrenous appendicitis. The median durations of surgery in Group A and Group B were 80 minutes (range, 40 to 195) and 60 minutes (range, 25 to 260), respectively (P < 0.005). Postoperative complication rates were comparable between the 2 groups (13.4% in Group A versus 15.8% in Group B). The median hospital stay for patients in Group A and Group B were 3.0 days (range, 1 to 47) and 4.0 days (range, 1 to 47), respectively (P = 0.037). CONCLUSIONS: We conclude that routine laparoscopy and LA for suspected acute appendicitis is safe and is associated with a significantly shorter hospital stay. Other intra-abdominal pathologies can also be diagnosed more accurately with the laparoscopic approach.     

Stump appendicitis after laparoscopic appendectomy; laparoscopic management and literature review

IntroductionAppendectomy is one of the most common surgical procedures performed worldwide There are different etiologies for acute appendicitis such as obstruction of the appendiceal lumen by fecalith, lymphoid hyperplasia, or neoplasm.Laparoscopic appendectomy has become the treatment of choice for both complicated and uncomplicated appendicitis; common postoperative complications include wound infection, bleeding, intraabdominal abscess.Stump appendicitis is defined as the interval repeated inflammation of remaining residual appendiceal tissue after an appendectomy.Presentation of case38-Year-old female patient with a history of laparoscopic appendectomy performed in 2016 for acute uncomplicated appendicitis.She arrived to the emergency room due to abdominal pain 7 out of 10, located in the periumbilical region, later with migration to the right lower quadrant, abdominal CT scan evidenced the presence of a cecal and pericecal inflammatory process as well as the base and residual proximal portion of the cecal appendix laparoscopic stump appendectomy was performed.DiscussionStump appendicitis (SA) is defined as the inflammation of the remnant of the cecal appendix after an appendectomy, whether due to impaction of a fecalith or secondary to an ischemic process, the probability of developing SA is estimated to be about 1/50,000 cases throughout life.The most frequently used treatment is exploratory laparotomy to complete the previous appendectomy; however, there are 5 reported cases of stump appendicitis, where surgical resolution was performed through laparoscopic surgery.ConclusionsIt is important to keep this entity in mind when evaluating a patient with acute abdomen with previous history of appendectomy, since the delay in diagnosis and treatment increases morbidity and mortality; laparoscopic stump appendectomy has been shown to be a safe treatment (Agha et al., 2020 [14]).¹     

Laparoscopic appendectomy for simple and complicated appendicitis in children--safe or risky procedure

OBJECTIVES: The aim of the study was to present our experience and to assess the advantages of laparoscopic appendectomy, particularly in children with perforated appendicitis. MATERIALS AND METHODS: Between 1999 and 2005, 505 laparoscopic appendectomies were performed. In children aged between 2 and 18 years, number, sex, age, histologic type of appendicitis, additional surgical procedures, number and type of complications, time of procedure, and hospitalization were analyzed. RESULTS: There was no need for conversion even in perforated appendicitis and in technically difficult cases. In 21 (4.16%) children in postoperative period minor complications occurred. Average operating time was 43 minutes. Average hospital stay was 2.4 days. CONCLUSIONS: Laparoscopic appendectomy is good alternative for classic appendectomy, irrespective of the degree of inflammation. Accurate cleaning and rinsing of the abdominal cavity essentially decreases the quantity of complications even in cases with perforated appendicitis. This suggests the expansion of indications toward laparoscopic appendectomy in case of all children with acute appendicitis.     

Laparoscopic appendectomy in children after the learning curve.

OBJECTIVES: Despite its increasing popularity, several recent studies comparing laparoscopic appendectomy (LA) with open appendectomy (OA) in children have failed to demonstrate significant improvements in patient outcomes. Many series include the "learning curve," wherein surgeons inexperienced with laparoscopic techniques compare their results with results with OA with its extensive history. This study was designed to investigate outcomes in pediatric appendectomy patients managed by surgeons with extensive laparoscopic experience. METHODS: We preformed a retrospective review of 197 consecutive children undergoing appendectomy for presumed acute appendicitis from January 2002 through May 2004 at a university-affiliated community hospital by pediatric and general surgeons with extensive laparoscopic surgical experience. RESULTS: The study included 117 patients who underwent LA and 80 who underwent OA. Of 122 acute appendicitis cases, mean operating times were 47 minutes (LA) and 48 minutes (OA). The LA group (n=71) had a faster return to full diet (17.6 h vs. 28.6 h, P=0.0008), and shorter postoperative length of stay (LOS) (1.06 d vs. 1.66 d, P<0.0001) compared with the OA group (n = 51). Complication rates, time on intravenous (IV) antibiotics, and IV opiates were similar among the 2 groups. Complicated appendicitis cases (LA, n=34; OA, n=26) were similar with regard to LOS, return to normal bowel function, complication rate and time on IV antibiotics and opiates, but was associated with an increased operation time (LA, 65 min; OA, 51 min, P=0.02). CONCLUSIONS: Following the completion of the laparoscopic surgery learning curve, LA has a comparable operation time and results in a decreased postoperative LOS, and faster return to normal bowel function compared with OA in children with acute nongangrenous, nonperforated appendicitis.     

A Single Case of Single-Port Access Laparoscopic Appendectomy During the Puerperium

Laparoscopic appendectomy is now widely practiced for the treatment of acute appendicitis. As result of increased demand for minimally invasive surgery, single-incision access was introduced and is being performed in various abdominal surgeries. Conventional laparoscopic appendectomy (LA) is gradually being performed in pregnant women. A 33-year-old woman was referred to our department at 39 weeks and 1 day of gestation due to abdominal pain. She was aware of her gastroepiploic pain even after the delivery. Though it was past 2 days, she was not recovering from right lower abdominal pain, so she was transferred to the Department of Gynecology at our hospital on the same day. Although an antibiotic was administered, the right abdominal pain did not improve, and she was referred to our department from the Department of Gynecology. We performed single-port LA (SP-LA). The total operation time was 63 minutes, and the estimated blood loss was 0 mL. She was discharged with no complications on postoperative day 7. We report our initial experience with single-port LA (SP-LA) using the glove technique for treatment of acute appendicitis in a postpartum woman. SP-LA using the glove technique was performed successfully during the puerperium without prolongation of operation time. This approach is less invasive, offers a much better cosmetic result than with conventional methods, and can be performed safely and at low cost.Key words: PLA (single-port laparoscopic appendectomy), PuerperiumThe advantages of laparoscopic appendectomy (LA) over open appendectomy (OA) are widely known and include decreased pain, shorter convalescence, and earlier return to work. Especially, LA is advantageous for treating acute appendicitis in pregnant women. Because the appendix of a pregnant woman is shifted from its normal position, OA may leave a larger operative scar than normal. In recent years, efforts of laparoscopic surgeons have resulted in a reduction in both the diameter of the access ports and the number of ports needed.¹ In addition, natural orifice transluminal endoscopic surgery (NOTES) is being developed as another form of minimally invasive surgery.² As a part of this process, the single-incision laparoscopic surgery (SILS) technique is presently being developed for various laparoscopic surgeries.³ SILS is a virtually scarless technique in which the single-port access site is hidden in the umbilicus. We think that the primary advantage of single-port laparoscopic appendectomy (SP-LA) is the superior cosmetic result compared with multi-port access LA. We report a very rare case in which SP-LA was performed to treat acute appendicitis during the puerperium. This approach is less invasive, offers a much better cosmetic result than with conventional methods, and can be performed safely and at low cost.     

Safety of Laparoscopic Appendectomy During Pregnancy

Background  Use of laparoscopic appendectomy (LA) remains controversial during pregnancy because data regarding procedure safety are limited. The outcome of LA in pregnant women was evaluated and compared to results of open surgery. Methods  Between January 1997 and December 2007, 42 pregnant women (mean age 24 years [range: 19–40 years]; range of gestation: 5–25 weeks) underwent appendectomy for suspected acute appendicitis: 23 laparoscopic (LA) and 19 open appendectomies (OA). Retrospective review of medical charts included preoperative information, surgery results, and outcome of the pregnancy. Results  There was no difference between groups in surgery delay following arrival at the hospital. All procedures, except one case of Meckel’s diverticulitis, were completed laparoscopically without need for conversion. Acute appendicitis was found in 19 cases and Meckel’s diverticulitis in one case during LA (87%) and in 18 cases (95%) during OA. Complicated appendicitis was found in 7 (30%) pregnant women in the LA group and 1 (5%) in the OA group. Five women with normal preoperative abdominal ultrasonography had acute appendicitis (2 in the OA group and 3 in the LA group). The laparoscopic procedure was performed more often by senior surgeons (70% of cases), and OA was more commonly done by residents (47% of cases). There were no intraoperative or postoperative complications recorded. The length of postoperative hospital stay was slightly prolonged after LA—2.4 days versus 1.4 day after OA. There was one fetal loss in each group, 1 and 2 months after the operation. Conclusions  Laparoscopic appendectomy is safe and effective during pregnancy and is associated with good maternal and fetal outcome.     

A Critical Analysis of Laparoscopic Appendectomy: How Experience with 1,400 Appendectomies Allowed Innovative Treatment to Become Standard in a University Hospital

BACKGROUND: Although advantages of laparoscopic appendectomy (LA) have not yet been proved, there is increasing evidence that LA provides diagnostic and therapeutic advantages as compared to conventional surgery. This article reports the introduction of LA in a university hospital where LA now represents the standard operative procedure in patients with suspected appendicitis. METHODS: Consecutive patients with appendectomy were prospectively included in the surgical database from 5/1991 to 10/2005. Operating time skin-to-skin in minutes, conversion from laparoscopy to open appendectomy, and complications requiring reoperation as well as surgical expertise were recorded. RESULTS: After initial performance of LA by four experienced specialists in laparoscopic surgery between 1991 and 1994, LA was routinely implemented from 1995 to 2005. Laparoscopic appendectomy was performed in 1,012 patients, and conventional appendectomy in 449 patients, with a LA rate of about 90% in recent years. Intraoperative conversion was deemed necessary in 62 patients (6.2 %) by 40 surgeons among the 103 surgeons who performed LA over 14 years with a mean operative time of 57 +/- 2 min. Between 1995 and 2005 about 25%-30% of LAs were performed as the first LA for the respective surgeon. Laparoscopic appendectomy was associated overall with a reduced length of stay in the hospital compared to open appendectomy (LA: 4.4 +/- 0.1 days versus 6.6 +/- 0.2 in open appendectomy; p < 0.001). CONCLUSIONS: This analysis provides evidence that LA can be introduced in an university hospital with acceptable results despite low operation numbers per surgeon and a liberal teaching policy. The LA procedure, which is associated with a 2%-4% rate of reoperation, may serve as laparoscopy training for young surgeons.     

Laparoscopic appendectomy. Initial experience in a teaching program.

From February 1990 to December 1991, 16 laparoscopic procedures were performed for right lower quadrant pain. There were nine men and seven women, aged 16 to 47 years (mean, 27.2 years). All procedures were performed by surgical chief residents with prior experience in laparoscopic cholecystectomy, first-assisted by an attending surgeon. The appendix was visualized and a definitive diagnosis was made in all patients. One patient with acute salpingitis underwent diagnostic laparoscopy only; two patients underwent laparotomy (perforated appendicitis, perforated diverticulitis). A fourth patient had an acute torsion of an ovarian cyst managed laparoscopically. Laparoscopic appendectomy was successfully performed in 12 patients (acute appendicitis, 9; fibrosis or chronic inflammation, 2; normal appendix, 1). Mean operative time for laparoscopic appendectomy was 95.7 minutes, and mean postoperative stay was 2.5 days. The authors conclude that operative time, diagnostic accuracy, and complication rates for laparoscopic appendectomy are acceptable. Within the context of a training program, laparoscopic appendectomy provides an opportunity for surgical residents to expand laparoscopic skills.

Can we afford to do laparoscopic appendectomy in an academic hospital?

BACKGROUND: Multiple studies have shown laparoscopic appendectomy to be safe for both acute and perforated appendicitis, but there have been conflicting reports as to whether it is superior from a cost perspective. Our academic surgical group, who perform all operative cases with resident physicians, has been challenged to reduce expenses in this era of cost containment. We recognize resident training is an expensive commodity that is poorly reimbursed, and hypothesized laparoscopic appendectomy was too expensive to justify resident teaching of this procedure. The purpose of this study was to determine if laparoscopic appendectomy is more expensive than open appendectomy. METHODS: From April 2003 to April 2004, all patients undergoing appendectomy for presumed acute appendicitis at our university-affiliated teaching hospital were reviewed; demographic data, equipment charge, minutes in the operating room (OR), hospital length of stay, and total hospital charge were analyzed. OR minute charges were gradated based on equipment use and level of skilled nursing care. Conversions to open appendectomy were included in the laparoscopic group for analysis. RESULTS: During the study period, 247 patients underwent appendectomy for preoperative diagnosis of acute appendicitis, with 152 open (113 inflamed, 37 perforated, 2 normal), 88 laparoscopic (69 inflamed, 12 perforated, 7 normal), and 7 converted (2 inflamed, 4 perforated, 1 normal) operations performed. The majority were men (67%) with a mean age of 31.4 +/- 2.2 years. Overall, there was significant difference (P < .05) in intraoperative equipment charge (125.32 dollars +/- 3.99 dollars open versus 1,078.70 dollars +/- 24.06 dollars lap), operative time charge (3,022.16 dollars +/- 57.51 dollars versus 4,065.24 dollars +/- 122.64 dollars), and total hospital charge (12,310 dollars +/- 772 dollars versus 16,773 dollars +/- 1,319 dollars) but no significant difference in operative minutes (56.3 +/- 1.3 versus 57.4 +/- 2.3), operating room minutes (90.5 +/- 1.7 versus 95.7 +/- 2.5), or hospital days (2.6 versus 2.2). In subgroup analysis of patients with uncomplicated appendicitis, open and laparoscopic groups had equivalent hospital days (1.47 versus 1.49) but significantly different hospital charges (9,632.44 dollars versus 14,251.07 dollars). CONCLUSIONS: Although operative time was similar between the 2 groups, operative and total hospital charges were significantly higher in the laparoscopic group. Unless patient factors warrant a laparoscopic approach (questionable diagnosis, obesity), we submit open appendectomy remains the most cost-effective procedure in a teaching environment.
