Conversion to open appendectomy should be done according to surgeon judgement, experience, and ability to treat the operative findings safely. Initial studies of laparoscopic appendectomy suggested higher costs because of the expense for equipment and the longer operative times . As surgeons and centers have gained experience, it is no longer clear that there is a higher cost with laparoscopy. The small differences in operative costs are offset by gains attributable to shorter hospital stays and quicker returns to work [15,16].
These factors are not entirely addressed by current studies. See the technical section for further discussion. There have been no randomized controlled trials comparing open and laparoscopic treatment of perforated appendicitis but multiple studies have established the feasibility and safety of LA. There is significant variability in complication rates, specifically infection rates, reported in the literature.
Level I evidence indicates that LA has a lower wound infection rate and a large population based study also identified LA to be associated with a lower infection rate .

The population studies showed shorter stays, and lower morbidity and mortality rates for the laparoscopic group. These findings were the same for all age groups and regardless of whether perforations had occurred or abscesses developed. Earlier studies showed a possible increased risk of intra-abdominal abscess IAA formation after LA for perforated appendicitis however more recent studies show no difference . Others have shown that with specialized laparoscopic teams, the IAA rate can be diminished .
Level 1, grade A.
With improved visualization of the entire abdomen, laparoscopy for the treatment of appendicitis improves the diagnostic accuracy and can identify the definitive pathology more often than the open approach [19, 20, 21, 22]. Level II, Grade B [8, 23]. Population based studies have shown a lower rate of complications and death, especially in the elderly 2. This supports the primary use of laparoscopic appendectomy for uncomplicated appendicitis in those centers possessing the requisite skills and equipment. For specific recommendations, reference may be made to IPEG guidelines.
Laparoscopic appendectomy can be performed safely in any trimester and is considered by many to be the standard of care for gravid patients with suspected appendicitis [24, 25, 26, 27].
The laparoscopic approach may convey some advantages over the open approach in access to the appendix, visualization, and decrease in wound complications. In the morbidly obese, longer trocars and instruments may be needed . Macroscopically normal appendixes may have abnormal histopathology. Therefore the risk of leaving a potentially abnormal appendix must be weighed against the risk of appendectomy in each individual scenario. Cases of postoperative symptoms requiring reoperation for appendectomy have been described in patients whose normal appendix was left in place at the time of the original procedure.
Laparoscopic appendectomy has been simplified by the development of electrocoagulating bipolar instruments, ultrasonic dissectors, and endoscopic staplers as well as improved camera optics. Experience has brought about a reduction in the size and number of ports. Mastery of the learning curve and proficiency in advanced laparoscopic techniques has decreased OR times. There is very little Level I evidence comparing particular techniques however some Level II and III evidence suggests that developing a consistent method decreases costs and OR time and decreases complications [18, 30].
This applies to laparoscopic appendectomy performed in a training program. One study involved the creation of a minimally invasive service. The use of standardized techniques, including peritoneal lavage following removal of the appendix has been shown to reduce the intraabdominal abscess rate  after a learning curve of 20 cases.
Foley placement, or voiding preoperatively in uncomplicated appendicitis, provides decompression of bladder which may help with exposure and avoid injury. Trocar placement: Basic principles of triangulation in trocar placement apply. All studies describe placement of the initial usually a 10mm camera port at the umbilicus. While port placement is at the discretion of the operating surgeon, the secondary port placements reported in the literature were:. Appendiceal retraction: Methods reported include simple retraction with a grasper via a 5mm port, a 5mm port placed directly above the appendix, an endotie around the end of the appendix to retract up, or a straight needle placed through the abdominal wall.
Guidelines are applicable to all physicians who address the clinical problem s without regard to specialty training or interests, and are intended to indicate the preferable, but not necessarily the only acceptable approaches due to the complexity of the healthcare environment. Guidelines are developed under the auspices of the Society of American Gastrointestinal and Endoscopic Surgeons and its various committees, and approved by the Board of Governors.

Disclaimer Guidelines for clinical practice are intended to indicate preferable approaches to medical problems as established by experts in the field. Utilization of Laparoscopy for Appendicitis Guideline: The indications for appendectomy are identical whether performed laparoscopically or open. Patient Selection A. Length of operation, post-operative pain, return to work. Complications and conversions.
Level II, grade B [8, 17] and is possibly the preferred approach level III, grade C There have been no randomized controlled trials comparing open and laparoscopic treatment of perforated appendicitis but multiple studies have established the feasibility and safety of LA. Level 1, grade A With improved visualization of the entire abdomen, laparoscopy for the treatment of appendicitis improves the diagnostic accuracy and can identify the definitive pathology more often than the open approach [19, 20, 21, 22].
Level II, Grade B [8, 23] Population based studies have shown a lower rate of complications and death, especially in the elderly 2. Special Considerations A. Treatment of normal appendix on laparoscopy for appendicitis GUIDELINE: If no other pathology is identified, the decision to remove the appendix should be considered but based on the individual clinical scenario.
Historical context Laparoscopic appendectomy has been simplified by the development of electrocoagulating bipolar instruments, ultrasonic dissectors, and endoscopic staplers as well as improved camera optics. While port placement is at the discretion of the operating surgeon, the secondary port placements reported in the literature were: LLQ and RUQ or R mid-abdomen.
One study found that fingerscopy may allow more efficient and full lysis of inflammatory adhesions and loculations and prevent incomplete appendectomy. RLQ and suprapubic. LLQ and suprapubic. Considerations: Having two working ports in adjacent quadrants i. LLQ and suprapubic positions allows the surgeon to work two-handed, rather than relying on an assistant to provide retraction while the surgeon dissects. Surgeons should consider the experience level of their assistant as well as the goals of a training program if they work in one.
Background: The treatment of patients with multiple synchronous tumors is challenging and complex. The use of next generation sequencing NGS may help in identification of germline mutations in genes involved in a common etiology for both tumors thus allowing a common effective therapeutic strategy. Patients and Methods: We describe the unexpected positive results obtained in a young woman with relapsed chemo-resistant stage IVB cervical and synchronous stage IV lung cancer, who underwent an interdisciplinary approach including palliative surgery with laparoscopic total pelvic exenteratio followed by a chemo-immunotherapy protocol with the anti- Programmed Death PD -1 antibody nivolumab plus metronomic cyclophosphamide.
The treatment choice was based on tumor PD-Ligand 1 assessment and NGS analysis for the identification of potential treatment targets. Outcomes included tumor objective response and patient-centered outcomes pain, performance status and overall quality of life.

After 3 and 6 months of treatment we observed an objective dimensional and metabolic response. Currently, after 24 months and 48 cycles of nivolumab the patient is continuing to benefit from treatment: she is in complete remission, with good performance status and she is working and leading a self-dependent life. Conclusion: Our study strongly affirms the efficacy of an interdisciplinary approach including surgical and innovative medical strategies based on immunotherapy in patients with advanced chemo-resistant synchronous cervical and lung cancer.
The present findings support the use of NGS to drive a targeted rational treatment especially in heavily pre-treated patients.
