Non-antibiotic treatment of uncomplicated acute diverticulitis is applicable and safe in our environment. A prospective multicenter study.

INTRODUCTION: acute diverticulitis is one of the most frequent underlying causes behind individuals attending the Emergency Room with abdominal pain. The most widespread therapy for acute uncomplicated diverticulitis includes outpatient treatment with antibiotics; however, several publications indicate that patients can also be successfully treated without antibiotics. The results of the implementation of this more recent protocol in two hospitals in Madrid are presented. METHODS: an observational prospective study was performed. Participants were patients diagnosed with uncomplicated acute diverticulitis at two hospitals in Madrid, Hospital Universitario de Torrejón and Hospital Universitario Puerta de Hierro Majadahonda, between December 2018 and August 2021, treated on an outpatient basis without antibiotic therapy. The study group was compared with a control group, composed of patients diagnosed with uncomplicated acute diverticulitis and treated with outpatient antibiotic therapy at Hospital Universitario Puerta de Hierro between March 2015 and March 2018. RESULTS: three hundred and sixty-one patients were included, 182 in the study group and 179 in the control group. Diverticulitis was persistent in 19 patients (10.4 %) in the study group, who were not treated with antibiotics, and in five patients (2.8 %) in the control group, treated with outpatient antibiotic therapy (p = 0.004). Recurrences occurred in 23 patients (12.6 %) in the study group, and in 53 patients (29.6 %) in the control group (p < 0.0001). The analysis of the complications found no significant differences between both groups (p = 0.109). No urgent surgical intervention or mortality was recorded in the study group. CONCLUSIONS: in our environment, symptomatic non-antibiotic treatment of uncomplicated acute diverticulitis cases is safe, without showing a higher rate of complications. Although, there seems to be a worse initial symptom control.

How to reduce the laparoscopic colorectal learning curve.

BACKGROUND: The laparoscopic approach for colorectal pathologies is becoming more widely used, and surgeons have had to learn how to perform this new technique. The purpose of this work is to study the indicators of the learning curve for laparoscopic colectomy in a community hospital and to find when the group begins to improve. METHODOLOGY: From January 1 2005 to December 31 2012, 313 consecutive laparoscopic colorectal surgeries were performed (105 rectal and 208 colonic) by at least 60% of the same surgical team (6 members) in each operation. We evaluate the learning curve by moving averages and cumulative sums (CUSUM) for different variables related to the surgery outcomes. RESULTS: Moving average curves for postoperative stay, fasting, and second step analgesia show a stabilizing trend toward improvement as we get more experience. However, intensive care unit stay, number of lymph nodes achieved, and operating time did not show a clear decreasing tendency. CUSUM curves of conversion, specimens<12 lymph nodes, and complications all show a clear turning point marked on all the charts around the procedure 60, accumulating a positive trend toward improvement. The CUSUM curve of the "learning variable" shows this improvement point at procedure 70. CONCLUSIONS: The laparoscopic colectomy learning curve accelerates with a collective team involvement in each procedure. The CUSUM and moving average curves are useful for initial and ongoing monitoring of new surgical procedures. The markers of the learning curve evidenced in our study are the conversion rate, postoperative surgical morbidity, and the number of patients with a lymph node count<12. WHAT IS NEW IN THIS PAPER?: The significance of this study is the evaluation of the learning curve, in laparoscopic colorectal surgery, of a surgical team in a community hospital, using moving average and CUSUM curves. This study demonstrated that the number of patients needed to achieve skilful practice decreased when there is collective team involvement in each procedure.

Laparoscopic hand-sewn gastrojejunal anastomoses.

BACKGROUND: Reconstruction of the digestive tract during gastric bypass (RYGBP) or biliopancreatic diversion (BPD) involves a mechanical or a hand-sewn gastrojejunal anastomosis. The object of this paper is to assess laparoscopic hand-sewn gastrojejunal anastomoses. METHODS: A series of morbidly obese patients was treated with RYGBP or BPD with a laparoscopic hand-sewn gastrojejunal anastomosis at the Hospital Universitario de Getafe-Madrid (Spain) between March 2001 and November 2007. RESULTS: The series comprised 250 patients, with 232 RYGBPs and 18 BPDs performed. The mean BMI was 46 +/- 4. Only a single case of gastrointestinal hemorrhage (0.4%) was recorded, caused by a marginal ulcer in the early postoperative period (day 6). In the late postoperative period, there were two cases of ulcer (0.8%), one complicated by hemorrhage, the other by perforation. There was no anastomotic leak. One patient (0.4%) required reintervention after 48 h because of thermal perforation of the gastric pouch. There were 11 cases of stenosis (4.4%) requiring radiologically or endoscopically guided dilatation, none in the BPD patients. Mean anastomosis time was 40 +/- 15 min. No cases of mortality or abscess, abdominal sepsis, or thromboembolism were recorded. Mean hospital stay was 5.1 +/- 2.4 days. CONCLUSIONS: Laparoscopic hand-sewn anastomoses are safe and reproducible by surgeons experienced in internal suturing and knot-tying. The technique lengthens operating time, but constant training develops the surgeon's skills, significantly shortening operating time.
