Retrospective analysis of transabdominal preperitoneal hernia repair in emergency cases: A cohort study.

PURPOSE: This study aimed to evaluate the feasibility, safety, and efficacy of laparoscopic transabdominal preperitoneal hernia repair (TAPP) for inguinal hernias in emergency settings, providing insights from a long-term follow-up. METHODS: We retrospectively analyzed all patients who underwent emergency TAPP repair in ASST Nord Milano from January 2005 to December 2023. A prospectively collected database of 54 consecutive TAPP hernia repairs was reviewed. The study evaluated the feasibility and safety of TAPP through operative time and the conversion rate. Effectiveness was gauged by recurrence and complication rates as well as acute and chronic pain using the Visual Analog Scale (VAS). Long-term follow-up included assessing recovery to normal activity. RESULTS: Overall, data from 54 consecutive patients were analyzed. Median age was 72 (IQR = 11), with 21 men and 33 women (38.8% vs. 61.2%). The primary diagnosis was a primary hernia (61.1%), while a recurrent type was identified in 21 patients (38.9%). Femoral hernia was identified in 36 cases (48%). The median operative time was 100 min (IQR = 53 min) with 6 cases of conversion (11.1%). One recurrence (1.85%) was noted and the complication rate was 5.55 %. At a median follow-up of 38 months, there was a low grade of chronic pain (VAS 3) in a patient (1.85%) and one recurrence (1.85%). CONCLUSION: TAPP is a safe, feasible, and effective option for emergency inguinal hernia repair, exhibiting low complication and recurrence rates on long-term follow-up when performed by surgeons with minimally invasive surgery experience and in selected patients.

Right-sided colonic diverticulitis. Short and long-term surgical outcomes and 2-year quality of life.

AIM: We aimed to investigate the short and the long-term outcomes and 2-year Quality of Life (QoL) of patients with right-sided colonic diverticulitis (RCD) surgically managed. METHOD: We conducted an ambidirectional cohort study of patients with RCD undergoing surgery between 2012/2022. A colonoscopy was performed at 1-year post surgery. The enrolled patients completed the EuroQoL (EQ-5D-3L) during a regular follow-up visit at 12 and 24 months after surgery. RESULTS: Three hundred nineteen patients with RCD were selected: 223 (70%) patients were treated by non-operative management (NOM) while 33 underwent surgery. Acute diverticulitis occurred in 30 patients: 9 (27.2%) were classified by CT as uncomplicated and 21 (63.6%) as complicated diverticulitis. Additionally, chronic diverticulitis occurred in 3 cases (9.2%). Specifically, 27 patients were classified by CT as 1a (81.8%) and 6 patients as 3 (18.2%). Right hemicolectomy was performed in 30 patients (90.8%), and ileo-caecectomy in 3 (9.2%). Nine (27.27%) experienced postoperative complications: 7 (77.7%) were classified according to the Clavien-Dindo as grade I-II, and 2 (22.2%) as grade III. No disease recurrence or colorectal cancer (CRC) was detected on colonoscopy. Thirty (90.8%) patients completed the 24-month follow-up. A statistically significant difference between preoperative and 24-month QoL index values (median 0.72; IQR = 0.57-0.8 vs. median 0.9; IQR = 0.82-1; p = 0.0003) was observed. CONCLUSIONS: The study results demonstrate satisfactory surgical outcomes and a better QoL after surgery. No disease recurrence or CRC was observed at colonoscopy 1 year after surgery.

Long-term results and quality of life after stapled hemorrhoidopexy vs Doppler-guided HAL-RAR: a propensity score matching analysis.

AIM: The study aimed to evaluate and compare the short and long-term outcomes of doppler-guided (DG) hemorrhoidal artery ligation and rectoanal repair (HAL-RAR) using a wireless-doppler-guided probe and stapled hemorrhoidopexy (SH) for treatment of II-III hemorrhoids. METHODS: This cohort study included patients who underwent HAL-RAR (n = 89) or SH (n = 174) for grade II-III hemorrhoids between January 2020 and December 2021. After propensity score matching at a 1:1 ratio, 76 patients for each group were analyzed. Short and long-term outcomes were collected. Pain was measured using a Visual Analogue Scale (VAS) at POD1, POD 10, 1 month, and 6 months after surgery. The enrolled patients completed the Hemorrhoidal Disease Symptom Score and Short Health ScaleHD quality of life (HDSS/SHS QoL) questionnaire preoperatively and during a regular follow-up visit at 24 months after surgery. RESULTS: Groups exhibited comparable overall postoperative complication rates (23% HAL-RAR/ 21% SH; p = 0.295). Postoperative pain via VAS showed median scores of 4, 3, 1, 1 for HAL-RAR and 6, 4, 2, 1 for SH at POD1, POD10, 1 month, and 6 months, respectively (p = < 0.001, 0.004, 0.025, 0.019). At a median follow-up of 12 months, the recurrence rate was 10.5% in the HAL-RAR group and 9.2% in the SH group (p = 0.785), respectively. At 24 months, 15.7% of HAL-RAR patients and 19.7% of SH patients remained symptomatic (p = 0.223). Median post-op QoL index was 1 (HAL-RAR) and 0.92 (SH), p = 0.036. CONCLUSIONS: HAL-RAR is a safe and feasible technique in treating grade II-III hemorrhoids showing better outcomes in terms of postoperative pain and QoL. SIGNIFICANCE: This paper adds a new perspective in comparing the HAL-RAR and SH, focusing the attention on the patients and not surgical techniques. A long and difficult follow-up was completed to fully understand the long-term results and the impact on the QoL of the patients who underwent these procedures.

The use of intra-abdominal prophylactic drainage in laparoscopic cholecystectomy: does it change in relation to surgical expertise? A multicenter case-control retrospective study on postoperative outcomes.

BACKGROUND: The routine use of abdominal drainage (AD) after laparoscopic cholecystectomy (LC) is still controversial. The aim of this expertise-based study is to evaluate the efficacy of prophylactic AD in terms of postoperative complications and analyze the factors linked to AD placement. METHODS: This case-control retrospective study included patients with cholelithiasis who underwent LC with AD (AD group) and LC without drainage (no-AD group) in two Italian centers. Allocation to groups was non-randomized and based on surgeons' decisions. Patient's characteristics, operative results, postoperative outcomes, surgeon's expertise related data were compared between the two groups with univariate and multivariate analysis. RESULTS: Patients in the two groups were comparable for age, sex ratio, and morbidity. Length of postoperative hospital stay (LOS) in the no-AD group was shorter than the AD group. Patients in the AD group had a higher rate of wound infection. No difference in postoperative pain measured 7 days after the surgery was found. Our results show an association between the first operator's expertise and age and the decision of placing the AD. The operative time seems to be the principal factor impacting the decision whether to place or not the AD. CONCLUSIONS: Our results indicate that it is feasible not to insert routine AD after elective LC for cholelithiasis. The use of AD seems to cause more cases of postoperative wound infections, prolongs the LOS and the operative time. The drain placement choice seems to change in relation to the surgeon's expertise.

Gastritis Cystica Profunda: A Rare Disease, a Challenging Diagnosis, and an Uncertain Malignant Potential: A Case Report and Review of the Literature.

Gastritis cystica profunda (GCP) has been defined as a rare submucosal benign gastric lesion with cystic gland growth. Due to its unclear etiopathogenesis, this lesion is often misdiagnosed and mistaken for other gastric masses. Currently, a standardized treatment for GCP lesions is still missing. Here, we illustrate a case of a patient admitted to our general surgery department for melena and general discomfort. No history of peptic ulcer or gastric surgery was present. Upper GI endoscopy was performed, showing a distal gastric lesion with a small ulceration on the top. CT-scan and endoscopic ultrasound confirmed the presence of the lesion, compatible with a gastric stromal tumor, without showing any eventual metastasis. Surgical gastric resection was performed. Histological findings were diagnostic for GCP, with cistically ectasic submucosal glands, chronic inflammation, eosinophilic infiltration and foveal hyperplasia. GCP is a very exceptional cause of upper-GI bleeding with specific histological features. Its diagnosis as well as its therapy are challenging, resulting in several pitfalls. Even though it is a rare entity, GCP should always be considered in the differential diagnosis of gastric submucosal lesions.

Standardization and learning curve in laparoscopic hernia repair: experience of a high-volume center.

PURPOSE: Groin hernias are a common condition that can be treated with various surgical techniques, including open surgery and laparoscopic approaches. Laparoscopic surgery has several advantages but its use is limited due to the complexity of the posterior inguinal region and the need for advanced laparoscopic skills. This paper presents a standardized and systematic approach to trans-abdominal pre-peritoneal (TAPP) groin hernioplasty, which is useful for training young surgeons. METHODS: The paper provides a detailed, step-by-step description of the TAPP based on evidence from literature, anatomical knowledge, and the authors' experience spanning over 30 years. The sample includes 487 hernia repair procedures, with 319 surgeries performed by experienced surgeons and 168 surgeries performed by young surgeons in training. The authors performed a descriptive analysis of their data to provide an overview of the volume of laparoscopic hernioplasty performed. RESULTS: The analysis of the data shows a low complication rate of 0.41% (2/487) and a low recurrence rate of 0.41% (2/487). The median duration of the surgery was 55 min, while the median operation time for surgeons in training was 93 min, specifically 83 min for unilateral hernia and 115 min for bilateral hernia. CONCLUSIONS: The TAPP procedure appears, to date, comparable to the open inguinal approach in terms of recurrence, postoperative pain and speed of postoperative recovery. In this paper, the authors challenge the belief that TAPP is not suitable for surgeons in training. They advocate for a training pathway that involves gradually building surgical skills and expertise. This approach requires approximately 100 procedures to achieve proficiency.

Anal canal gastrointestinal stromal tumour (GIST).

SummaryGastrointestinal stromal tumours (GISTs) are malignant mesenchymal tumours that originate from the interstitial pacemaker cells of Cajal. They are particularly rare, comprising only 5% of all GISTs, and often present at an advanced stage. Treatment for these tumours is still a topic of debate due to their low incidence and insidious location. A woman in her mid-70s presented with rectal bleeding and anal discomfort. A 4.5×4 cm anal GIST was diagnosed. A local excision was performed and the patient was further treated with tyrosine kinase inhibitors. At a 6-month follow-up, the MRI showed that she was disease free. Anorectal GISTs are unusual and tend to be aggressive. Surgical resection is the first-line treatment for primary, localised GISTs. However, the appropriate surgical technique for these tumours is still a topic of debate. Further studies are needed to fully understand the oncologic behaviour of these rare neoplasms.

Predictive factors of recurrence for laparoscopic repair of primary and incisional ventral hernias with single mesh from a multicenter study.

Laparoscopic ventral hernia repair (LVHR) is a widely practiced treatment for primary (PH) and incisional (IH) hernias, with acceptable outcomes. Prevention of recurrence is crucial and still highly debated. Purpose of this study was to evaluate predictive factors of recurrence following LVHR with intraperitoneal onlay mesh with a single type of mesh for both PH and IH. A retrospective, multicentre study of data collected from patients who underwent LVHR for PH and IH with an intraperitoneal monofilament polypropylene mesh from January 2014 to December 2018 at 8 referral centers was conducted, and statistical analysis for risk factors of recurrence and post-operative outcomes was performed. A total of 1018 patients were collected, with 665 cases of IH (65.3%) and 353 of PH (34.7%). IH patients were older (p < 0.001), less frequently obese (p = 0.031), at higher ASA class (p < 0.001) and presented more frequently with large, swiss cheese type and border site defects (p < 0.001), compared to PH patients. Operative time and hospital stay were longer for IH (p < 0.001), but intraoperative and early post-operative complications and reinterventions were comparable. IH group presented at major risk of recurrence than PH (6.7% vs 0.9%, p < 0.001) and application of absorbable tacks resulted a significative predictive factor for recurrence increasing the risk by 2.94 (95% CI 1.18-7.31). LVHR with a light-weight polypropylene mesh has low intra- and post-operative complications and is appropriate for both IH and PH. Non absorbable tacks and mixed fixation system seem to be preferable to absorbable tacks alone.

Use of oxidized regenerated cellulose to achieve hemostasis during laparoscopic cholecystectomy: a retrospective cohort analysis.

OBJECTIVE: Laparoscopic cholecystectomy is the first-choice treatment for symptomatic cholelithiasis. Though generally safe, this procedure is not without complications, with bleeding the most frequent cause of conversion to open cholecystectomy. Oxidized regenerated cellulose (ORC) added to conventional hemostatic strategies, is widely used to control bleeding during surgery despite limited evidence supporting its use. This retrospective study analyzed patients undergoing laparoscopic cholecystectomy in an Italian center over a 16-month period, between October 2014 and February 2016, who experienced uncontrollable bleeding despite the use of conventional hemostatic strategies, requiring the addition of ORC gauze (Emosist®). RESULTS: Of the 530 patients who underwent laparoscopic cholecystectomy, 24 (4.5%) had uncontrollable bleeding from the liver bed. Of these, 62.5% had acute cholecystitis and 33.3% chronic cholecystitis; 1 patient was diagnosed with gallbladder carcinoma, postoperatively. Most patients had comorbidities, 16.7% had liver cirrhosis, and 37.5% used oral anticoagulants. The application of ORC rapidly controlled bleeding in all patients. Patients were discharged after a mean duration of 2.2 days. ORC was easy to use and well tolerated. Bleeding complications remain a relevant issue in laparoscopic cholecystectomy. ORC was able to promptly stop bleeding not adequately controlled by conventional methods and appears, therefore, to be a useful hemostat.

The sleeve gastrectomy intervention to treat morbid obesity in a Parkinson's disease patient.

BACKGROUND & AIMS: Some Parkinson's disease patients may develop morbid obesity, on account of the reduction in exercise and/or of the appearance of compulsive food intake in the first years after diagnosis. The prescription of central appetite suppressants is actually not recommended in Parkinson's disease patients. To the best of our knowledge, no cases of morbidly obese Parkinson's disease patients submitted to bariatric surgery procedures have been reported in literature before. METHODS: We here describe for the first time the outcome of a sleeve gastrectomy intervention in a morbidly obese Parkinson's disease patient, resistant to several non-surgical weight-loss treatments. RESULTS: The outcome of the sleeve gastrectomy intervention was satisfactory in terms of body weight-loss, long term weight stabilization and improvement of cardioprotective circulating factors, including adiponectin. Furthermore, the antiparkinson therapy (levodopa) was reduced by 25%. CONCLUSIONS: These observations suggest that morbidly obese Parkinson's disease patients, who are resistant to other dietary treatments, might be candidated for sleeve gastrectomy.

Laparoscopic appendectomies: experience of a surgical unit.

Appendicitis is one of the most common causes of acute abdomen in adults and appendectomy is the most common emergency abdominal procedure. Laparoscopic appendectomy has gained popularity only in recent years and the optimal approach for the treatment of acute appendicitis is still under debate. This retrospective study aimed at examining the current indications for laparoscopic appendectomy. 1024 patients undergoing laparoscopic appendectomy between February 1992 and December 2007 were retrospectively reviewed. 39.9% of patients (n=408) underwent emergency surgery. In 616 cases (60.1%) conservative management was performed in vain and these patients underwent an elective operation. In the 36 patients with an intraoperative normal appendix, other pathological findings were laparoscopically detected and treated. Conversion to an open procedure was required for 13 (1.3%) cases. The mean operative time was 38 min and the average length of postoperative hospitalization was 2.5 days. The overall morbidity rate was 2.6%. Laparoscopic appendectomy should be considered a procedure of choice for the treatment of non-complicated appendicitis. We stress the possibility to laparoscopically treat even complicated appendicitis in the surgical setting with substantial experience in minimally invasive surgery.

Left pneumothorax secondary to colonoscopic perforation of the sigmoid colon: a case report.

We present here the case of a 75-year-old woman who complained of acute abdominal pain after a diagnostic colonoscopy. Abdominal x-rays demonstrated pneumoperitoneum, whereas chest x-rays showed pneumomediastinum and left pneumothorax. A chest drain was placed and subsequently an exploratory laparoscopy was performed, during which air was found in the subserosa of the sigmoid colon and in the mesosigmoid secondary to perforation of a sigmoid diverticulum. The perforation was repaired and a protective loop colostomy was fashioned. The patient was discharged 8 days postoperatively in a good general condition. Although numerous cases of pneumoretroperitoneum and pneumomediastinum secondary to iatrogenic perforation of the colon have been described, reports of pneumothorax are much rarer. We, therefore, discuss the anatomic bases and the possible physiopathologic mechanisms responsible for this clinical complication.

Use of human fibrin glue (Tissucol) versus staples for mesh fixation in laparoscopic transabdominal preperitoneal hernioplasty: a prospective, randomized study.

OBJECTIVE: The aim of this study was to compare the morbidity of fixation of prosthetic meshes using Tissucol fibrin glue versus staples in laparoscopic transabdominal preperitoneal (TAPP) repair of inguinal and femoral hernias. SUMMARY BACKGROUND DATA: In patients undergoing laparoscopic hernia repair, fixation of mesh prostheses with staples may affect inguinocrural nerves causing early postoperative neuralgia and chronic neuralgia. METHODS: Between June 2003 and February 2005, 197 patients with inguinal or femoral hernia were enrolled in this prospective, randomized study, to assess morbidity following hernia repair with staples (n = 98) or Tissucol (n = 99). The primary outcomes were early postoperative and late neuralgia recorded using a visual analog scale (VAS). The effects of neuralgia on functional status were evaluated using the modified SF-36 questionnaire. Secondary outcomes included complications such as nonspecific pain and recurrence. RESULTS: Assessments took place at 1, 3, 6, and 12 months, with all patients completing each follow-up visit. Mean VAS scores were significantly lower in the Tissucol group versus the staples group (MANOVA, P < 0.05). Higher scores for the modified SF-36 questionnaire at 1 month were demonstrated in the Tissucol group compared with the staples group (23.2 and 22.6, respectively; P < 0.05). The mean recovery time for normal physical activity was significantly shorter in the Tissucol group compared with the staples group (7.9 vs. 9.1 day, respectively; P < 0.001). One recurrence was seen in the fibrin glue group, which was attributable to a technical error in fixation of the mesh. CONCLUSIONS: The use of Tissucol provides distinct advantages in laparoscopic treatment of inguinal/femoral hernias compared with conventional TAPP, including a lower incidence of postoperative neuralgia and an earlier resumption of physical and social activities.
