Objective: Single port laparoscopy andNOTES aim at decreasing the number¦of trocars, at a price of increased technical difficulty and cost, without until now¦any proof of benefit for the patient.Morbidity related to 5 mm trocar sites (TS)¦is claimed to be low, but there are no good quality data on this topic. The aim¦of the present prospective study is to measure the morbidity and overall specific¦impact related to the 5 mm TS and compare them to larger TS.¦Methods:Wecollected prospectively data on 300 consecutive patients operated¦by laparoscopy in our institution between 2009 and 2010. Pain, morbidity,¦cosmetic, and overall patient discomfort were assessed specifically for each¦TS, using standardized questionnaires, at 3 time points: at discharge from¦the hospital, at 1 month and at 6 months after surgery. Results were compared¦between 5 mmand larger TS (10 mm, 12 mmand 15 mm).Trocar sites replaced¦by a minilaparotomy or a stoma were excluded from analysis. In this study we¦present the short-term results.¦Results: Three-hundred patients (mean age 47·5, women 55%) were operated¦with 1074 TS of which 477(44%) were 5 mm TS. Indication to laparoscopy was¦cholecystectomy (31·3%), appendectomy (26·6%), upper GI surgery (16·3%),¦colon resection (13·3%) or other (12·3%). Follow-up at 1 month was completed¦in 90%.¦The 5 mm TS had an infection rate of 0·2%, and a hematoma rate of 1·7%.¦VAS pain scores at the 5mm TS were ≤3 in 91·6% at rest and in 75·9% upon¦effort at discharge, and in 97% at 1 month. Median patient scar assessment¦score (PSAS) of the 5 mm TS at 1 month was 6 (IQR: 2-9) out of 60 (0 =¦best score). Overall discomfort of the 5 mm TS in a VAS scale was 0 in 77%¦and ≤3 in 95% of patients at 1 month. Morbidity, pain assessments, PSAS, and¦overall discomfort scores were all significantly better for 5 mm TS compared to¦larger TS.¦Conclusion: Morbidity, pain, cosmetic impact and overall patient's discomfort¦related to a 5 mm trocar site is extremely low. For this reason, any potential¦advantage related to omitting 5 mm trocars to perform the same type of surgery¦will be difficult to demonstrate.
