Peroral Endoscopic Myotomy for Achalasia after Bariatric Surgery: A Case Report and Review of the Literature.

INTRODUCTION: Achalasia following bariatric surgery is a rare phenomenon with diverse potential physiopathological origins. AIMS: This article aims to explore the hypothetical physiopathological connection between bariatric surgery and the subsequent onset of achalasia. MATERIAL AND METHODS: A review was conducted to identify studies reporting cases of peroral endoscopic myotomy (POEM) after bariatric procedures and detailing the outcomes in terms of the technical and clinical success. Additionally, a case of a successful POEM performed on a patient two years after undergoing laparoscopic sleeve gastrectomy (LSG) is presented. RESULTS: The selection criteria yielded eight studies encompassing 40 patients treated with POEM for achalasia after bariatric surgery: 34 after Roux-en-Y gastric bypass (RYGB) and 6 after LSG. The studies reported an overall technical success rate of 97.5%, with clinical success achieved in 85% of cases. Adverse events were minimal, with only one case of esophageal leak treated endoscopically. However, a postprocedural symptomatic evaluation was notably lacking in most of the included studies. CONCLUSIONS: Achalasia poses a considerable challenge within the bariatric surgery population. POEM has emerged as a technically viable and safe intervention for this patient demographic, providing an effective treatment option where surgical alternatives for achalasia are limited. Our findings highlight the promising outcomes of POEM in these patients, but the existing data remain limited. Hence, prospective studies are needed to elucidate the optimal pre-surgical assessment and timing of endoscopic procedures for optimizing outcomes.

Laparoscopic bariatric surgery is safe during phase 2-3 of COVID-19 pandemic in Italy: A multicenter, prospective, observational study.

BACKGROUND: Sars-Cov-2 epidemic in Italy caused one of the greatest 2020 European outbreaks, with suspension of elective bariatric/metabolic surgery (BMS). From May 2020 a significant decline of the epidemic has been observed (phase 2); National Health Service protocols permitted elective BMS' resumption. A new, more severe COVID-19 surge, the "second wave", started on October 2020 (phase 3). AIM: The primary end point was to analyze the outcomes of any Sars-Cov-2 infection and related morbidity/mortality within 30 POD after laparoscopic BMS during phase 2-3; secondary end points were readmission and reoperation rates. METHODS: Study design prospective, multicenter, observational. SETTING: Eight Italian high-volume bariatric centers. All patients undergoing BMS from July 2020 through January 2021 were enrolled according to the following criteria: no Sars-Cov-2 infection; primary procedures; no concomitant procedure; age > 18 < 60 years; compensated comorbidities; informed consent including COVID-19 addendum; adherence to specific admission, in-hospital and follow-up protocols. Data were collected in a prospective database. Patients undergone BMS during July-December 2019 were considered a control group. RESULTS: 1258 patients were enrolled and compared with 1451 operated on in 2019, with no differences for demographics, complications, readmission, and reintervention rates. Eight patients (0·6%) tested positive for Sars-Cov-2 infection after discharge, as well as and 15 healthcare professionals, with no related complications or mortality. CONCLUSIONS: Introduction of strict COVID-19 protocols concerning the protection of patients and health-care professionals guaranteed a safe resumption of elective BMS in Italy. The safety profile was, also, maintained during the second wave of outbreak, thus allowing access to a cure for the obese population.

Enhanced recovery after bariatric surgery (ERABS) in a high-volume bariatric center.

BACKGROUND: The growing demand for bariatric surgery has been accompanied by an expensive technological evolution and the need to contain healthcare costs and to increase the quality of care. The enhanced recovery after surgery (ERAS) protocols applied to the bariatric setting can be the answer to all these different issues. OBJECTIVES: Feasibility and safety of ERAS protocol in a single, high-volume bariatric center. SETTING: Humanitas Research Hospital, Rozzano MI, Italy. METHODS: Our ERAS bariatric protocol is based on the following 3 steps: (1) preoperative: optimization of all co-morbidities, counseling patients and family with information and education, and shortening fasting times (clear fluids up to 2 hr and solids up to 4 hr before induction of anesthesia); (2) intraoperative: premedication, parallel team work, awake patient positioning, standardized multimodal anesthesia and analgesia, noninvasive monitoring, video-laryngoscopy in reverse Trendelenburg position, short-acting anesthetic agents, and standardized laparoscopic surgery avoiding the nasogastric tube, catheter, and drain; and (3) postoperative: analgesia, early mobilization, early oral fluid, thromboprophylaxis, discharge planning, and follow-up telephone call. Clinical pathways were established and outcomes were retrospectively collected. RESULTS: Comparison between conventional care and ERAS protocol reveals a reduction of the length of hospital stay (from 4.7 to 2.1 d) and a low morbidity rate. From July 2015 to July 2018, a total of 2400 consecutive patients underwent primary or revisional bariatric surgery (2122 sleeve gastrectomies and 278 Roux-en-Y gastric bypasses [RYGB]). Mean body mass index was 44.9 kg/m2, mean age was 41.9 years, and the male to female ratio was 1:2.5. Total mean operative time was 85 minutes, with a surgical time of 65 minutes and an anesthesiologic/patient induction time of 4 minutes. Early complication rate was 3.5% with no perioperative mortality. Mean hospital stay was 2.1 days and the rate of readmission was .9%. CONCLUSIONS: This study demonstrates that our ERAS protocol is safe, feasible, and efficient. Patient preparation and multidisciplinary/parallel team work are crucial points.

Surgery to Treat Symptomatic Mobile Cecum Syndrome Is Safe and Associated with Good Recovery Outcomes.

The mobile cecum syndrome includes a spectrum of conditions. The cecal volvulus represents the acute form, with typical feature of a bowel obstruction that needs immediate operative treatment. On the other hand, a chronic form of mobile cecum syndrome which is the most common form reported a history of intermittent crampy abdominal pain, distension, and constipation. In this study, five patients came to our attention during the last ten years, presenting different symptoms due to a mobile cecum. All patients were investigated by several diagnostic techniques according to the specific clinical setting. All patients were found to have the cecum and ascending colon unattached to the posterior peritoneum. Surgery was the treatment of choice. In our experience, the best diagnostic technique was computed tomography scan, especially if performed in the Trendelenburg position. We also propose virtual colonoscopy as a good option for diagnosis (in patients with chronic syndrome) and follow-up after surgery. In conclusion, laparoscopic approach guaranteed a good result, with no symptoms of recurrence, in both acute and elective treatments. The diagnosis of mobile cecum needs a high index of suspicion and a targeted radiological investigation. Surgery, especially laparoscopic cecopexy and appendectomy, is the recommended treatment.

Laparoscopic sleeve gastrectomy in a patient with situs viscerum inversus totalis: is the life easy upside-down?

INTRODUCTION: Obesity is an epidemic on the rise [1]. The number of bariatric procedures has increased worldwide. Laparoscopic sleeve gastrectomy (LSG) is a valid therapeutic option, leading to a sustained weight loss with a low complication rate [2]. Situs viscerum inversus totalis (SIT) is the complete transposition of all the abdominal organs, occurring in about 1 in 10,000 people [3]. Laparoscopic approach in SIT is challenging due to the mirror image anatomy. MATERIALS AND METHODS: We present the case of a 41-year-old man with a body mass index of 46.4 kg/m2 (131 kg; 1.68 m) previously diagnosed with SIT who has undergone LSG. RESULTS: In this video, we show a LSG performed in a patient with SIT. There were no changes in the technique compared to the "standard anatomy." The patient was placed on the operative table in anti-trendelenburg position with legs abducted. The surgeon stood between the legs while the assistant was on the right side of the patient and the scrub nurse on the opposite side. A 12-mm trocar was inserted with a direct technique in the right lateral flank. Carbon dioxide insufflation was done under vision. Other three trocars (12, 10, and 5 mm) were positioned in the left lateral flank, supraumbilical, and subxiphoid areas, respectively. Gastroepiploic dissection started at 5 cm from the pylorus up to the right crus. After the insertion of a 36-Fr boogie, an accurate stapling of the stomach was performed. The proximal side of the sleeve was reinforced with a non-absorbable suture. Titanium clips were placed leading to a complete haemostasis. The procedure lasted 45 min. The patient followed a "fast-track" protocol afterwards, with no changes in the perioperative workup compared to "standard anatomy" patients. He was discharged on day 2 postoperatively and no complication occured in the perioperative period. CONCLUSION: SIT is a rare condition leading to a mirror image that can be challenging for a laparoscopic surgeon. LSG is feasible and safe also for morbidly obese patients with SIT, not requiring any change in the surgical technique and perioperative management, as long as the surgeon is well beyond the learning curve.

Sleeve gastrectomy leads to easy management of hormone replacement therapy and good weight loss in patients treated for craniopharyngioma.

The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m2 (range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m2 (range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.

Metastases to the thyroid gland from renal cancer.

AIMS AND BACKGROUND: Metastases to the thyroid gland from renal cancer pose a challenge to physicians, due in part to the rarity of the phenomenon, the prolonged time interval between removal of the primary renal cancer and the appearance of metastases, the difficulty in diagnosis, and the uncertainty regarding long-term prognosis. We report our experience with diagnosis and management of patients affected by thyroid metastases from renal clear cell carcinoma. STUDY DESIGN: We report herein three clinical cases of thyroid metastases from renal clear cell carcinoma. We also present a review of the literature and examine common features of clinical presentation and management recommendations. RESULTS: Over the past 17 years, 918 patients underewent surgery for thyroid cancer in our institution. Histological examination demonstrated a thyroid secondary malignancy from kidney cancer in 3 cases. Two patients underwent total thyroidectomy, whereas in the third patient a palliative right lobectomy with homolateral latero-cervical lymphoadenectomy was performed. At a 5-year follow-up, only one patient survived and was disease-free. CONCLUSIONS: Thyroid metastases from renal clear cell carcinoma are a rare occurrence but should be taken into consideration in the differential diagnosis of a thyroid nodule. Preoperative diagnosis is often difficult. Nevertheless, an extensive diagnostic workup is recommended because the subsequent therapy must be tailored on the basis of the local extension of metastases. Surgical treatment of solitary thyroid metastases is recommended. However, patients with disseminated disease have a poor prognosis, and palliative care is the indicated recommendation. In these patients and in surgically untreatable patients, prolonged survival may be achieved by adjuvant medical therapy.

Tako-tsubo cardiomyopathy as initial presentation of pheocromocytoma. A clinical case.

INTRODUCTION: Tako-tsubo cardiomyopathy is a rapidly reversible form of acute heart failure triggered by stressful events that occur more frequently in postmenopausal women. A central role is supposed to be played by catecholamines and the association with pheocromocytoma is rare. CASE PRESENTATION: We describe a patient admitted for abdominal pain and suffering of hypertension pharmacologically treated. During hospitalization the patient presented cephalea and precordial pain with nausea and profuse sweating. ECG showed ST elevation and deep negative T wave. Blood tests were moderately elevated. Echo-cardiography reported a left ventricular apex akynesia and hyperkynesia of the base while coronarography was negative. As hypertension persisted the suspicion of pheocromocytoma arose. Urinary and blood catecholamines were mildly elevated and echography and Magnetic Resonance revealed a left adrenal gland mass. The diagnosis of pheocromocytoma was thus confirmed Left laparoscopic adrenalectomy was performed after adequate stabilization and preoperative pharmacological preparation by hydration, a-and f-blockers. Intraoperatively blood pressure was controlled by nitroprussiate, rapid half life beta-blockers (esmolol cloridrate). Post-operative course was uneventful and arterial pressure returned to normal as well as catecholamines values. Patient was discharged on the 5th post-operative day Five months afterwards the patient had normal arterial pressure without anti-hypertensive therapy and symptom free. CONCLUSION: The case confirmed that tako-tsubo cardiomyopathy could be the first manifestation of tumors secreting catecholamines and that pheocromocytoma should be considered in patients with hypertension and acute stress-induced cardiomiopathy without evidence of acute coronary disease and with negative coronarography.
