ABSTRACT
BACKGROUND: Although index cholecystectomy is considered the treatment of choice for acute cholecystitis (AC), many hospital systems struggle to provide such a service. The aim of this study was to analyze the effect of failure to perform index cholecystectomy in patients presenting with acute cholecystitis. METHODS: Between June 2010 and December 2015, all patients presenting to one hospital with an initial attack of AC were enrolled into a prospective database. Patient's records were reviewed up until point of delayed cholecystectomy or for a minimum of 24 months after the initial presentation with AC. Recurrent AC was defined as early (<6 weeks from initial discharge) or late (>6 weeks from initial discharge). RESULTS: In total 998 patients presented with AC, 409 (41%) of whom were discharged without index cholecystectomy. Eighty-three (20%) patients presented with AC recurrence (ACR). Compared to the first AC episode, patients were more likely to present with grade III AC and suffer significantly greater morbidity (p < 0.05 for all comparisons). A prior history of biliary disease was associated with ACR (p = 0.002). ACR occurred early in 48 (58%) patients and delayed in 35 (42%) patients. CONCLUSIONS: Twenty percent of patients discharged without cholecystectomy after their first attack of ACR will develop recurrence within the first two years. Half of ACR will occur within 6 weeks. Patients who present with ACR are more likely to develop more severe AC and are likely to suffer greater morbidity as compared to their first attack.

The closure of the abdominal wall after making a laparotomy is a major challenge for surgeons, since a significant percentage of closures fail and incisional hernias rise. The suture has to withstand the forces required to close the incision, while not hindering the adequate wound healing progression. Currently, there is no surgical measuring device that could be used to determine the required closing forces, which can be very different depending on the patient. This paper presents a dynamometer to measure the tension forces to be applied while closing a surgical incision, and it simultaneously measures the distance between wound edges. It is a compass-like instrument. A mechanism between the two legs incorporates a load cell, whose signal is read by an electronic device that computes the values of the tension forces between wound edges. An angular position sensor at the pin joint between legs provides the distance between both sides of the incision. Measuring capabilities of the instrument prototype were verified at the laboratory. Thereafter, its functionality was demonstrated in experimental surgery tests. Therefore, the instrument could be very useful in clinical applications, assisting personalized surgical techniques.
