Brief Summary

The potential benefit of outpatient care for this common digestive emergency is considerable, both for the patients themselves and for the public health system:

1. Optimization of the care pathway, reducing the length of stay in hospital (a major issue in the context of the COVID-19 (coronavirus disease) pandemic) liberating patient beds and staff, and reducing the risk of nosocomial exposure.

2. Improved patient satisfaction compared to waiting for hours in the emergency department due to lack of hospital beds.

3. Non-inferiority of care in an outpatient unit in terms of quality and safety in day hospitalization.

4. Significant decrease in the overall cost of this pathology as a result of a reduction in the hospital stay.

  • Affiliation to a French health insurance scheme or equivalent

Exclusion Criteria
  • Criteria that exclude ambulatory care such as an ASA score (Physical status score) > 2, severe or uncontrolled comorbidities, severe pulmonary disease including obstructive sleep apnea, anticoagulation or antiplatelet drug or contraindication to ambulatory surgery such as intubation difficulties
  • Presence of active cancer, a malignant hemopathy, drug addiction, coagulopathy, immunosuppressive treatment
  • Non-acute or interval appendectomy, i.e. after antibiotic treatment of a complicated appendicitis of the plastron or drainage of an appendicular abscess;
  • History of pelvic surgery

Pregnant women are considered to have a full stomach, with risk of inhalation at anesthetic induction and represent a contraindication to ambulatory surgery. In addition, the need to perform abdominal surgery on a pregnant woman requires obstetric monitoring that is difficult to reconcile with management in an outpatient surgery unit (need for obstetric ultrasound or monitoring).
  • Suspicion of a tumor of the appendix : Mucocele and pseudomyxoma, Carcinoid tumor, Adenocarcinoma of the appendix, Another type of tumor

Primary Outcome Measures
NameTimeMethod
To demonstrate that outpatient care, compared with conventional care, in selected patients with acute uncomplicated appendicitis operated by laparoscopy, is non-inferior in terms of overall morbi-mortality on the 30th postoperative day.30 days post surgery

Morbi-mortality will be assessed by classifying post-operative complications according to Clavien-Dindo classification. It will be compared between both groups ("ambulatory pathway" versus "conventional hospitalization" CONV) on the 30th postoperative day.

The Clavien-Dindo classification was originally published in 2004 in the Annals of Surgery for elective general surgery. Later, it has been objectively validated for all surgical specialties. This classification ranks complications from 0 (no complication) to 5 (death). Complications that potentially lead to long-lasting disability after discharge (e.g.: paralysis of a vocal cord after thyroid surgery) are highlighted in the present classification by a suffix ("d" for disability). This suffix indicates that a long-term follow-up is required to comprehensively evaluate the outcome and related long-term quality of life.

Secondary Outcome Measures
NameTimeMethod
To study the economic impact (utility) of outpatient appendectomy management compared to conventional hospitalizationup to the 30th day post surgery

The economic impact will be studied with a cost-utility analysis which will estimate the incremental cost-effectiveness ratio (ICER) in cost per QALY (quality adjusted life years) gained.

To compare between both groups, the rate of interventional radiology re-intervention (radio-guided drainage)up to the 30th day post surgery

All the Clavien-Dindo interventional radiology re-interventions (radio-guided drainage) performed in relation with the appendicitis and any potential complications will be recorded up to the 30th day post surgery.

To compare between both groups, the mild morbidity (Clavien-Dindo I-II) during 30 days post surgeryup to the 30th day post surgery

Post-operative mild morbidity will be assessed with the Clavien-Dindo classification (grade I, II) up to the 30th day post surgery. Clavien-Dindo classification was originally published in 2004 in the Annals of Surgery for elective general surgery. Later, it has been objectively validated for all surgical specialties. This classification ranks complications from 0 (no complication) to 5 (death).

To compare between both groups, the rate of laparoscopic re-interventionup to the 30th day post surgery

All laparoscopic re-interventions performed in relation with the appendectomy and the potential complications will be recorded up to the 30th day post surgery.

To compare between both groups, at post-operative day 30, the rate of re-intervention by laparotomyup to the 30th day post surgery

All the laparotomic re-interventions performed in relation with the appendectomy and the potential complications will be recorded up to the 30th day post surgery.

To evaluate the rate of conversion from outpatient to conventional careup to the 30th day post surgery

A conversion will be defined as a patient randomized to the outpatient care group who is finally treated following the conventional care procedure, whatever the reason

To estimate the cost of outpatient appendectomy managementup to the 30th day post surgery

The cost will be estimated by the hospital cost (intervention and outpatient stay).

To compare between both groups, at post-operative day 30, the rehospitalization rate30 days post surgery

All re-hospitalization(s) after initial discharge will be counted until 30 days post surgery, whatever the cause or type of hospitalization.

To compare between both groups, patient satisfaction 7 and 30 days post surgery7 and 30 days post surgery

Patient satisfaction will be assessed using a numerical scale from 0 to 10, using the Link4Life app. Zero '0', placed on the left, means that the patient is not satisfied at all with her/his postoperative course; '10', placed on the right, means that the patient is extremely satisfied with her/his postoperative course. If the patient does not have access or does not wish to access Link4Life, a clinical research assistant from the investigating center will collect the patient's satisfaction through a phone call. The questions that will be asked are: "How satisfied are you with your care?"; "are you in pain and if so, how severe is it?"; "Were you worried about same-day discharge (for patients in the outpatient group)?

To study the generalization of outpatient appendectomy management in all French hospitals at the budgetary levelup to the 30th day post surgery

The generalization of outpatient appendectomy management will be studied with a budget impact model which will estimate the consequences in terms of costs

To compare between both groups, at post-operative day 30, the delay from diagnosis to appendectomy30 days post surgery

The delay from diagnosis to appendectomy is defined as the time between the performance of the CT scan (or ultrasound or MRI) for diagnosis and the skin incision in the operating room. This time is expressed in minutes.

To compare between both groups, at post-operative day 30, the real cumulated length of hospitalization30 days post surgery

The real cumulated length of hospitalization is the cumulative length of the entire hospital stay(s) in hours until the 30th postoperative day (rehospitalizations included). The length of stay in a non-hospital health structure, such as a convalescent center, will not be included.

To compare between both groups, the severe morbidity (Clavien-Dindo III, IV, V) during 30 days post surgeryup to the 30th day post surgery

Post-operative mild morbidity will be assessed with the severe morbidity (Clavien-Dindo III, IV, V) up to the 30th day post surgery. Clavien-Dindo classification was originally published in 2004 in the Annals of Surgery for elective general surgery. Later, it has been objectively validated for all surgical specialties. This classification ranks complications from 0 (no complication) to 5 (death).

To compare between both groups, patient quality of life 7 and 30 days post surgeryat inclusion and at 7 and 30 days post surgery

Quality of life will be evaluated using the EuroQol five-dimension questionnaire (EQ-5D-5L), at inclusion, and at 7 and 30 days post surgery.The EQ-5D-5L comprises a descriptive system and a visual analogue scale (VAS). The descriptive system is composed of five health dimensions (mobility, self-care, usual activities, pain/discomfort and anxiety/depression) with 5 levels of health (no problems, slight problems, moderate problems, severe problems and extreme problems). For each of the 5 dimensions, the participant's answer is converted to a number between 1 and 5, expressing the health state reported. The responses are combined to produce a five-digit number describing the participant's health status which is converted to a utility value from the country specific value set. The French EQ-5D-5L value set has utility between -0.530 (health condition worse than death) and 1 (best possible health). The VAS records the self-rated health status on a graduated scale from 0 to 100.

To study the economic impact (effectiveness) of outpatient appendectomy management compared to conventional hospitalizationup to the 30th day post surgery

The economic impact will be studied with a cost-effectiveness analysis which will estimate the ICER in cost per patient without rehospitalization.

To study the generalization of outpatient appendectomy management in all French hospitals at a strategic levelup to the 30th day post surgery

The generalization of outpatient appendectomy management will be studied with QALYs (quality adjusted life years) of the adoption of the outpatient strategy in all French hospitals
